MR HONDA helliphelliphellip A MAN AND HIS DREAM

He dreamed of providing people everywhere in the world an economical means of transportation He thought of better ways of making piston rings and found a company amp began production Then his company started producing small motorcycles including one built in 1949 called D-type dream

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 6

Then he thought of making high capacity motorcycles and taking them to racing So his company made bigger and faster machines two- four- five- and six-cylinder race bikes and participated in the Isle of Man TT race (125 cc motorcycle class)

He wanted to share his new motorcycles with the world and therefore he opened American Honda Motor Co in Los Angeles Also Honda began manufacturing motorcycles at its Suzuka factory in 1960 Honda launched its first sports car the S500 in Japan and entered Formula-1 in 1964

In 1989 Soichiro Honda became the first Asian to be inducted into US Automotive Hall of Fame In 1990 Honda wins its fifth consecutive 1st ranking in the JD Power Consumer Satisfaction Index In 1993 founder Soichiro Honda passed away He dreamed of changing the way people looked at motorcycles and gave us machines that were powerful amp fun to ride SOICHIRO HONDArsquoS dreams changed the world of motorcycling

8 Introduction to Maintenance Department

Introduction The maintenance department is one of the most important departments of the organization where the organization has its own production Maintenance department of Honda Motorcycle and Scooter India Private Limited (HMSI) is a responsible for all the breakdowns which occur in the machines or where there is any production loss so when to overcome the problem of production loss maintenance team has to work efficiently so that there is no mistake committed by them by which production loss occurs

Some important definitions used by maintenance

Maintenance Action necessary for retaining or restoring an equipment machine or system to the specified operable condition to achieve its maximum useful life It includes planned and preventive maintenance

Planned Maintenance Preventive maintenance carried out according to a fixed plan is called planned maintenance

Preventive Maintenance Systematic inspection detection correction and prevention of incipient failures before they become actual or major failures is called as preventive maintenance

Breakdown Maintenance Repair or replacements performed after a machine has failed to return to its functional state following a malfunction or shutdown is called as breakdown maintenance

Predictive Maintenance Type of preventive maintenance performed continuously or at interval according to the requirement to diagnose and

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 36

monitor a condition or system also called condition based maintenance is called as predictive maintenance

Mean Time To Repair (MTTR) Basic measure of maintainability of repairable items it represents the average mean time required to repair a failed component or device is defined as mean time to repair

Mean Time Between Failures (MTBF) Basic measure of the reliability of repairable items it represents the average number of a life units during which all parts of a device or system perform within their specified limits under specified conditions are called as mean time between failures

Down Time Period during which an equipment or machine is not functional or cannot work It may be due to technical failures mechanical adjustments maintenance or non availability of inputs such as materials labor and power etc is called as down time

Frame Maintenance In this department there are three sections

1 Press Section

2 Weld Section

3 Paint Section

PRESS SECTION Press section has mainly four machines

Komatsu Pressndash3

AIDA Press -1

CNC bending machine

Hind Press

These presses are mechanical presses and on this press mudguard fuel tank nose and body cover of the scooters like activa aviator dio shine twister unicorn and twister Process like blanking coining and bending of pipes is done

Blanking is cutting up a large sheer of stock into smaller pieces suitable for next operation

Coining is the process of removal of extra material or to make work piece up to the limit All these mechanical presses are of 500 ton and there only one hydraulic press and this press are used to repair the dyes

CNC pipe bending machines are used to bend the pipes which later used in the manufacturing of the frame

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 38

WELDING SECTION In welding section there are six types of welding machines used in manufacturing of frames and body covers

1 Gantry System Gantry system is a system in which gantry crane is used for transporting the frame and welding is done by the robots and welding is finished by the robots the gantry crane picks up the frame and body covers and puts them on the conveyer or the hanger which goes to the weld body storage On gantry system seam welding is done on the body covers and on the frames with the help of the welding robots This system is fully automatic and there is no involvement of human being it picks up the frame and body covers from the location defined to it then does all the processing on it and then passes it to the conveyer

2 MIG Welding Metal inert gas welding in this inert gas argon is used and argon acts as a shielding gas 1-5 oxygen is used This type of welding uses consumable wire electrode during the welding process that is fed from the wire spool MIG welding has some advantages over the other welding techniques It provides a uniform weld it provides a slag free weld beam and needs little clean up

3 Spot Welding Spot welding is a process in which contacting metal surface are joined by the heat obtained from resistance to electric flow and this type of welding is done on the body covers of the scooter

4 Seam Welding It is a process that welds at a surface of overlapped parts along a length of a joint Weld made by overlapping nuggets this type of welding is done on the fuel tanks and mudguards of scooter

5 Portable Spot Welding It is a portable gun which can be taken to specified range where other spot welding machine faces difficulty in welding This type of the welding is done on body covers of scooters

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 39

6 Fine Boring Fine boring is done on the frame where handle has to fit after fine boring handle is attached to it

When various operation of the welding on the different components of the scooter that is frame mudguard body covers and fuel tank is over then this welded body parts are loaded on to a conveyer hanger which takes these body parts to the weld body storage and in the weld body storage and in weld body storage there are three sections one for model 1 one for model 2 and the last for model 3 When welded body is loaded on to a conveyor then the person who loads these bodies on to the hanger select in which model hanger has to go and the selection is done with a selector switch present Up to 300 hangers can be stored in the storage area that means around 600 frames and 600 body covers can be stored in the weld storage area From storage area hangers move to the unloading area and from unloading area these body covers and frames are loaded on to a Carrier which takes them to the paint section Unloading of the frames and body covers depends on the requirement of the assembly line and which model they are making according to their requirement unloading of model frames and body covers is done Unloading of the model is again done by the selector switch that is when there is requirement of model 1 the person who unloads the frame presses model switch and from storage model 1 moves to the unloading area Similarly when there is requirement of model 2 then operator presses model 2 switch and same goes for the model 3 when the requirement is of model 3 the operator presses the model 3 switch and then from storage model 3 moves to unloading bay

1 Sanding Zone

2 Under Coat

3 Top Coat

Loading In this process frames and body covers are mounted on the carrier of the conveyor line There are two lines for the paint that is paint A line and paint B line both the lines are very much important because in A line loading of frames and front body left right cover and rear body covers are loaded and on B line mudguard and front cowl is loaded and after loading of these parts then the carrier moves to the pretreatment zone

Pre-Treatment In pre-treatment degreasing and dust cleaning is done In pre-treatment bodies have to undergo two operations first wasting with the soft water by this process degreasing is done and all the dust particles are removed from the frames and body covers In general first we get hard water is converted to soft water by ion exchange mechanism

Secondly on bodies and frames phosphate cleaning is done by this method any dust particle or any grease particle left on the frames and body cover is removed

Electro-Deposition In electro deposition carrier which carries frame and body covers turn down into the electro deposition chamber and in electro deposition chamber is filled with the base paint or primer When carrier turns down it strikes high voltage wire and it gets negatively charged and become cathode and paint in the chamber becomes anode then a uniform thin film of base paint is deposited on

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 42

the body covers and frames of the scooter This process is repeated twice and after that it is passed to ED oven

ED Oven In electro deposition oven base coat done on the frame and body covers is heated to 150 degree temperature and this base coat is dried here and after that is passed to paint booth

Paint Booth Paint booth has three sections first one is sanding zone second primary coat or under coat and third is top coat

In sanding zone sanding of the frames and body covers is done and after that it is sent to under coat zone in under coat zone single coat of the paint is done on frames and body covers and in this zone coat of paint is done with the help of robots and after that frames and body covers then sent to top coat zone here in this zone second coat of the paint is done and this second coat of paint is done with the operator and after that these frames and body covers are sent to top coat oven

Top Coat Oven In top coat oven these frames and body covers are heated up to 170 degree temperature and dried and then allowed to cool naturally to room temperature and from there it is sent to the inspection zone

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 43

Inspection Zone In inspection zone body covers and frames have to pass infra-red zone Here IR testing machine checks for irregularities in the paint done and after that these body covers and frames are manually checked by hand for any errors in the paint jobs Parts which pass these tests get the OK mark and move to unloading area

Unloading In this area unloading of frames and body covers takes place Frames and body covers having OK mark are loaded to the paint body store and body covers and frames not having OK mark on them are sent to the repair work station and there they fix the problems which frames and body covers have They are then unloaded and then loaded on to the hanger and the parts go to the paint body storage In storage final or finished body covers and frames are stored which from storage area moves to the final assembly line

9 ProjectProject Definition

To study the various parts of the carrier being used in the paint shop and its problem analysis

Project Introduction

Carrier is defined as a thing which supports or holds up a part during its movement It is used to carry parts to the paint shop where various processes can be performed Carrier forms the basis of the Paint Shop because the movement of the parts from one point to another in the paint shop takes place only due to carrier The parts are loaded on the carrier with the help of a jig and then the motion takes place

Paint shop carrier is the most important moving part in the paint process Most problems and the breakdowns in the paint shop occur due to the carrier only It causes loss to the net production Bends or breaks due to load of body part applied on carrier causes distortions which ultimately results in the breakdown

Carrier is a part of the conveyer system being used in the paint shop The other components of the conveyer system are the prime mover drive (works as the input motion source for chain) chain and chain track carrier carrier turn (for turning the carrier) carrier

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 45

revolution (for revolving the carrier) stopper (it temporarily stops the carrier on line) carrier locks auto feeder cylinders and drop lifters which support the motion of carrier

Part Description Of Carrier

Rail

Rail can be of two types ie pre rail and power rail Pre rail is used to drive trolley of the carrier Power rail is used to drive the conveyer system

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 46

Gear Box

Gear Box acts as a Speed Reducer It consists of a worm and worm-wheel arrangement which turns the axis of rotation by 90deg and reduces the speed of the parts The gear box is coupled with the small sprocket Gear transmits power to small sprocket which helps for carrier turn this is also called as reduction gear The relation between the torque and diameter of worm shaft is given by

T (Kg-m) = π16dsup3τ

where τ is the twisting moment

Velocity Ratio = 160

Tensile Strength of Material = 60 Kgmmsup2

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 47

Trolley

There are two trolleys present in a carrier namely Front and the Rear Trolley Front Trolley stops the carrier at a specified position by the actuation of stopper while Rear Trolley stops the next carrier by engaging with the Front trolley of next carrier Trolley Wheel contains ball bearings The outer race serves as a wheel A grease fitting is installed as a greasing port Guide Roller is installed to reduce friction against free rail Pivoting Dog is lifted by the own weight The chain pusher engages to the Pivoting dog for transport To stop the carrier the stopper (installed on the line) pushes down the Pivoting Dog to release the engagement with the pusher

Swivel Pipe

Swivel pipe is used to drive carrier during carrier revolution Swivel pipe is connected to the shaft of worm gear thus it also gets its power from the gear box

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 48

Big Sprocket

It comes in contact with the chain of the carrier turn and is responsible for rotation of the carrier It is mounted on the spindle on which the pan cover is fixed Four carrier dogs are attached to it which control the rotation of the carrier Big sprocket is attached to the spindle shaft plate

Small Sprocket

It is attached to the shaft connected to gear box It comes in contact with the chain of carrier revolution and is responsible for the revolution of the carrier

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 49

Tension Spring

Spring is used to lock turning plate thus stopping carrier revolution It happens when there is no load on the spring But when the load is applied turning plate opens and hence carrier revolution occurs

Insulator Collar

It provides insulation to the carrier in ED process so that there is no current in the frame To avoid the flow of current in the rail of the conveyer system and to avoid damage to the whole system insulator collars are provided

Post

It is mounted on the pan cover and holds the jig by locking it at its position Post mainly has three parts post cover post spacer and post spacer

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 50

Coupling

Bush Coupling transfers the motion from small sprocket shaft to input shaft To avoid overloading at the gear box bush coupling is provided

Guide Pin Arm

It locks the turning of the Big Sprocket by elongating the spring connected to it It has three contact points one is the spring one touches the guide pin of the carrier turn and third is for the engagement and disengagement of big sprocket

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 51

ED Collector

ED collector is used to collect current during ED process and transmits it through the cables to the body parts

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 52

End Striker amp Turn Striker

Problem Analysis Of Carrier

Frame Hole NG

During the motion of the carrier when it is suddenly stopped by the stopper vibrations are produced in it and the pin inserted in the hole of the frame enlarges the size of the hole thereby causing the problem of frame hole NG

To reduce this problem an anti back-up system is applied to reduce the vibrations The NG frame hole is repaired by welding a bush at the site of the hole which is a newly developed Kaizen

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 64

Problems Caused By Loading

Improper loading of the frame body on the carrier damages the insulator collar because an unbalanced force acts upon it and insulator collars being the non-metallic parts are severely affected

R is the resultant vector

This is a production problem which causes the bending of jigs unbalancing of the carrier thereby causing improper motion at the carrier turns and revolutions and also resulting in the body parts falling in the oven

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 65

Gear Box Failure

Gear box of the carrier also fails some time due to overloading or improper coupling

Bending of Striker

Overloading at CTs and CRs causes the bending of the strikers which result in altered motion of the carrier

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 66

Breaking of Post

The post of the carrier can be broken due to variable and unbalanced load acting on the carrier The stresses are developed in the post which leads to its breaking Moreover hammering of the nut for the proper locking can also cause the breaking of nut

Overloading

Overloading is the state when the load on a part of the carrier is higher than its tolerance value Its causes are

If any object interrupts the motion of chain chain is not able to move forward properly causing overloading of chain

Improper position of the jig may lead to unbalancing of the carrier and overload may occur

Guide pin may not properly interact with the arm which may lead to non-alignment

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 67

Chain of the carrier turn may not be in proper position leading to overload at CT

Breaking of any of the carrier dogs will lead to improper revolution of the carrier

Other Problems

Cable breaks -gt Current does not reach to body part

ED COLLECTER burns out -gt It would not collect current

Threading of endndashplate striker wear out -gt Striker would not hit limit switch

Bush between coupling is cut

Bearing sometimes disrupts system

Swivel pipe bends -gt Carrier wouldnrsquot be leveled

Insulator sometimes fails to stop current

End plate threading wears

Spindle shaft bends -gt Carrier wouldnrsquot be leveled

Striker and arm also bends

Conclusion

From my project of one month here in HMSI I came to know that how

work goes on in the organization As far as my project of study

maintenance and breakdown analysis of carrier is concerned I came to

know the importance of carrier in paint shop and the production

problems caused by the carrier in the industry The carrier being used in

the paint shop is the best possible system for proper painting of parts

By knowing the various specifications problems related to it can be

solved

The Human Being is born as a free and unique individual with the capacity to think reason and create ---- and the ability to dream Respect for the individual calls on Honda to nurture and promote these characteristics in our company by respecting individual differences and trusting each other as equal partners

Respect for the Individual recognizes the following core concepts

Initiative Initiative means not to be bound by preconceived ideas but think creatively and act on your own initiative and judgment while understanding that you must take responsibility for the results of those actions

Equality Equality means to recognize and respect individual differences in one another and treat each other fairly Our company is committed to this principle and creating equal opportunities for each individual An individualrsquos race sex age religion national origin educational background social or economic status have no bearing on the individualrsquos opportunities

Trust The relationship among associates at Honda should be based on mutual trust Trust is created by recognizing each other as individuals helping out where others are deficient accepting help

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 27

8 Introduction to Maintenance Department

Introduction The maintenance department is one of the most important departments of the organization where the organization has its own production Maintenance department of Honda Motorcycle and Scooter India Private Limited (HMSI) is a responsible for all the breakdowns which occur in the machines or where there is any production loss so when to overcome the problem of production loss maintenance team has to work efficiently so that there is no mistake committed by them by which production loss occurs

Some important definitions used by maintenance

Maintenance Action necessary for retaining or restoring an equipment machine or system to the specified operable condition to achieve its maximum useful life It includes planned and preventive maintenance

Planned Maintenance Preventive maintenance carried out according to a fixed plan is called planned maintenance

Preventive Maintenance Systematic inspection detection correction and prevention of incipient failures before they become actual or major failures is called as preventive maintenance

Breakdown Maintenance Repair or replacements performed after a machine has failed to return to its functional state following a malfunction or shutdown is called as breakdown maintenance

Predictive Maintenance Type of preventive maintenance performed continuously or at interval according to the requirement to diagnose and

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 36

monitor a condition or system also called condition based maintenance is called as predictive maintenance

Mean Time To Repair (MTTR) Basic measure of maintainability of repairable items it represents the average mean time required to repair a failed component or device is defined as mean time to repair

Mean Time Between Failures (MTBF) Basic measure of the reliability of repairable items it represents the average number of a life units during which all parts of a device or system perform within their specified limits under specified conditions are called as mean time between failures

Down Time Period during which an equipment or machine is not functional or cannot work It may be due to technical failures mechanical adjustments maintenance or non availability of inputs such as materials labor and power etc is called as down time

Frame Maintenance In this department there are three sections

PRESS SECTION Press section has mainly four machines

Komatsu Pressndash3

AIDA Press -1

CNC bending machine

Hind Press

These presses are mechanical presses and on this press mudguard fuel tank nose and body cover of the scooters like activa aviator dio shine twister unicorn and twister Process like blanking coining and bending of pipes is done

Blanking is cutting up a large sheer of stock into smaller pieces suitable for next operation

Coining is the process of removal of extra material or to make work piece up to the limit All these mechanical presses are of 500 ton and there only one hydraulic press and this press are used to repair the dyes

CNC pipe bending machines are used to bend the pipes which later used in the manufacturing of the frame

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 38

WELDING SECTION In welding section there are six types of welding machines used in manufacturing of frames and body covers

1 Gantry System Gantry system is a system in which gantry crane is used for transporting the frame and welding is done by the robots and welding is finished by the robots the gantry crane picks up the frame and body covers and puts them on the conveyer or the hanger which goes to the weld body storage On gantry system seam welding is done on the body covers and on the frames with the help of the welding robots This system is fully automatic and there is no involvement of human being it picks up the frame and body covers from the location defined to it then does all the processing on it and then passes it to the conveyer

2 MIG Welding Metal inert gas welding in this inert gas argon is used and argon acts as a shielding gas 1-5 oxygen is used This type of welding uses consumable wire electrode during the welding process that is fed from the wire spool MIG welding has some advantages over the other welding techniques It provides a uniform weld it provides a slag free weld beam and needs little clean up

3 Spot Welding Spot welding is a process in which contacting metal surface are joined by the heat obtained from resistance to electric flow and this type of welding is done on the body covers of the scooter

4 Seam Welding It is a process that welds at a surface of overlapped parts along a length of a joint Weld made by overlapping nuggets this type of welding is done on the fuel tanks and mudguards of scooter

5 Portable Spot Welding It is a portable gun which can be taken to specified range where other spot welding machine faces difficulty in welding This type of the welding is done on body covers of scooters

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 39

6 Fine Boring Fine boring is done on the frame where handle has to fit after fine boring handle is attached to it

When various operation of the welding on the different components of the scooter that is frame mudguard body covers and fuel tank is over then this welded body parts are loaded on to a conveyer hanger which takes these body parts to the weld body storage and in the weld body storage and in weld body storage there are three sections one for model 1 one for model 2 and the last for model 3 When welded body is loaded on to a conveyor then the person who loads these bodies on to the hanger select in which model hanger has to go and the selection is done with a selector switch present Up to 300 hangers can be stored in the storage area that means around 600 frames and 600 body covers can be stored in the weld storage area From storage area hangers move to the unloading area and from unloading area these body covers and frames are loaded on to a Carrier which takes them to the paint section Unloading of the frames and body covers depends on the requirement of the assembly line and which model they are making according to their requirement unloading of model frames and body covers is done Unloading of the model is again done by the selector switch that is when there is requirement of model 1 the person who unloads the frame presses model switch and from storage model 1 moves to the unloading area Similarly when there is requirement of model 2 then operator presses model 2 switch and same goes for the model 3 when the requirement is of model 3 the operator presses the model 3 switch and then from storage model 3 moves to unloading bay

PAINT SECTION Paint section is very important section In this section different treatments are done on the body covers and frames and it is a step by step process done as follows

Loading

Pre-Treatment

Electro-Deposition

ED Oven

Booth

Top Coat Oven

Inspection Zone

Unloading

PAINT PROCESS FLOW

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 41

1 Sanding Zone

2 Under Coat

3 Top Coat

Loading In this process frames and body covers are mounted on the carrier of the conveyor line There are two lines for the paint that is paint A line and paint B line both the lines are very much important because in A line loading of frames and front body left right cover and rear body covers are loaded and on B line mudguard and front cowl is loaded and after loading of these parts then the carrier moves to the pretreatment zone

Pre-Treatment In pre-treatment degreasing and dust cleaning is done In pre-treatment bodies have to undergo two operations first wasting with the soft water by this process degreasing is done and all the dust particles are removed from the frames and body covers In general first we get hard water is converted to soft water by ion exchange mechanism

Secondly on bodies and frames phosphate cleaning is done by this method any dust particle or any grease particle left on the frames and body cover is removed

Electro-Deposition In electro deposition carrier which carries frame and body covers turn down into the electro deposition chamber and in electro deposition chamber is filled with the base paint or primer When carrier turns down it strikes high voltage wire and it gets negatively charged and become cathode and paint in the chamber becomes anode then a uniform thin film of base paint is deposited on

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 42

the body covers and frames of the scooter This process is repeated twice and after that it is passed to ED oven

ED Oven In electro deposition oven base coat done on the frame and body covers is heated to 150 degree temperature and this base coat is dried here and after that is passed to paint booth

Paint Booth Paint booth has three sections first one is sanding zone second primary coat or under coat and third is top coat

In sanding zone sanding of the frames and body covers is done and after that it is sent to under coat zone in under coat zone single coat of the paint is done on frames and body covers and in this zone coat of paint is done with the help of robots and after that frames and body covers then sent to top coat zone here in this zone second coat of the paint is done and this second coat of paint is done with the operator and after that these frames and body covers are sent to top coat oven

Top Coat Oven In top coat oven these frames and body covers are heated up to 170 degree temperature and dried and then allowed to cool naturally to room temperature and from there it is sent to the inspection zone

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 43

Inspection Zone In inspection zone body covers and frames have to pass infra-red zone Here IR testing machine checks for irregularities in the paint done and after that these body covers and frames are manually checked by hand for any errors in the paint jobs Parts which pass these tests get the OK mark and move to unloading area

Unloading In this area unloading of frames and body covers takes place Frames and body covers having OK mark are loaded to the paint body store and body covers and frames not having OK mark on them are sent to the repair work station and there they fix the problems which frames and body covers have They are then unloaded and then loaded on to the hanger and the parts go to the paint body storage In storage final or finished body covers and frames are stored which from storage area moves to the final assembly line

9 ProjectProject Definition

To study the various parts of the carrier being used in the paint shop and its problem analysis

Project Introduction

Carrier is defined as a thing which supports or holds up a part during its movement It is used to carry parts to the paint shop where various processes can be performed Carrier forms the basis of the Paint Shop because the movement of the parts from one point to another in the paint shop takes place only due to carrier The parts are loaded on the carrier with the help of a jig and then the motion takes place

Paint shop carrier is the most important moving part in the paint process Most problems and the breakdowns in the paint shop occur due to the carrier only It causes loss to the net production Bends or breaks due to load of body part applied on carrier causes distortions which ultimately results in the breakdown

Carrier is a part of the conveyer system being used in the paint shop The other components of the conveyer system are the prime mover drive (works as the input motion source for chain) chain and chain track carrier carrier turn (for turning the carrier) carrier

Problem Analysis Of Carrier

Frame Hole NG

During the motion of the carrier when it is suddenly stopped by the stopper vibrations are produced in it and the pin inserted in the hole of the frame enlarges the size of the hole thereby causing the problem of frame hole NG

To reduce this problem an anti back-up system is applied to reduce the vibrations The NG frame hole is repaired by welding a bush at the site of the hole which is a newly developed Kaizen

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 64

Problems Caused By Loading

Improper loading of the frame body on the carrier damages the insulator collar because an unbalanced force acts upon it and insulator collars being the non-metallic parts are severely affected

R is the resultant vector

This is a production problem which causes the bending of jigs unbalancing of the carrier thereby causing improper motion at the carrier turns and revolutions and also resulting in the body parts falling in the oven

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 65

Gear Box Failure

Gear box of the carrier also fails some time due to overloading or improper coupling

Bending of Striker

Overloading at CTs and CRs causes the bending of the strikers which result in altered motion of the carrier

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 66

Breaking of Post

The post of the carrier can be broken due to variable and unbalanced load acting on the carrier The stresses are developed in the post which leads to its breaking Moreover hammering of the nut for the proper locking can also cause the breaking of nut

Overloading

Overloading is the state when the load on a part of the carrier is higher than its tolerance value Its causes are

If any object interrupts the motion of chain chain is not able to move forward properly causing overloading of chain

Improper position of the jig may lead to unbalancing of the carrier and overload may occur

Guide pin may not properly interact with the arm which may lead to non-alignment

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 67

Chain of the carrier turn may not be in proper position leading to overload at CT

Breaking of any of the carrier dogs will lead to improper revolution of the carrier

Other Problems

Cable breaks -gt Current does not reach to body part

ED COLLECTER burns out -gt It would not collect current

Threading of endndashplate striker wear out -gt Striker would not hit limit switch

Bush between coupling is cut

Bearing sometimes disrupts system

Swivel pipe bends -gt Carrier wouldnrsquot be leveled

Insulator sometimes fails to stop current

End plate threading wears

Spindle shaft bends -gt Carrier wouldnrsquot be leveled

Striker and arm also bends

MR HONDA helliphelliphellip A MAN AND HIS DREAM

He dreamed of providing people everywhere in the world an economical means of transportation He thought of better ways of making piston rings and found a company amp began production Then his company started producing small motorcycles including one built in 1949 called D-type dream

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 6

Then he thought of making high capacity motorcycles and taking them to racing So his company made bigger and faster machines two- four- five- and six-cylinder race bikes and participated in the Isle of Man TT race (125 cc motorcycle class)

He wanted to share his new motorcycles with the world and therefore he opened American Honda Motor Co in Los Angeles Also Honda began manufacturing motorcycles at its Suzuka factory in 1960 Honda launched its first sports car the S500 in Japan and entered Formula-1 in 1964

In 1989 Soichiro Honda became the first Asian to be inducted into US Automotive Hall of Fame In 1990 Honda wins its fifth consecutive 1st ranking in the JD Power Consumer Satisfaction Index In 1993 founder Soichiro Honda passed away He dreamed of changing the way people looked at motorcycles and gave us machines that were powerful amp fun to ride SOICHIRO HONDArsquoS dreams changed the world of motorcycling

8 Introduction to Maintenance Department

Introduction The maintenance department is one of the most important departments of the organization where the organization has its own production Maintenance department of Honda Motorcycle and Scooter India Private Limited (HMSI) is a responsible for all the breakdowns which occur in the machines or where there is any production loss so when to overcome the problem of production loss maintenance team has to work efficiently so that there is no mistake committed by them by which production loss occurs

Some important definitions used by maintenance

Maintenance Action necessary for retaining or restoring an equipment machine or system to the specified operable condition to achieve its maximum useful life It includes planned and preventive maintenance

Planned Maintenance Preventive maintenance carried out according to a fixed plan is called planned maintenance

Preventive Maintenance Systematic inspection detection correction and prevention of incipient failures before they become actual or major failures is called as preventive maintenance

Breakdown Maintenance Repair or replacements performed after a machine has failed to return to its functional state following a malfunction or shutdown is called as breakdown maintenance

Predictive Maintenance Type of preventive maintenance performed continuously or at interval according to the requirement to diagnose and

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 36

monitor a condition or system also called condition based maintenance is called as predictive maintenance

Mean Time To Repair (MTTR) Basic measure of maintainability of repairable items it represents the average mean time required to repair a failed component or device is defined as mean time to repair

Mean Time Between Failures (MTBF) Basic measure of the reliability of repairable items it represents the average number of a life units during which all parts of a device or system perform within their specified limits under specified conditions are called as mean time between failures

Down Time Period during which an equipment or machine is not functional or cannot work It may be due to technical failures mechanical adjustments maintenance or non availability of inputs such as materials labor and power etc is called as down time

Frame Maintenance In this department there are three sections

1 Press Section

2 Weld Section

3 Paint Section

PRESS SECTION Press section has mainly four machines

Komatsu Pressndash3

AIDA Press -1

CNC bending machine

Hind Press

These presses are mechanical presses and on this press mudguard fuel tank nose and body cover of the scooters like activa aviator dio shine twister unicorn and twister Process like blanking coining and bending of pipes is done

Blanking is cutting up a large sheer of stock into smaller pieces suitable for next operation

Coining is the process of removal of extra material or to make work piece up to the limit All these mechanical presses are of 500 ton and there only one hydraulic press and this press are used to repair the dyes

CNC pipe bending machines are used to bend the pipes which later used in the manufacturing of the frame

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 38

WELDING SECTION In welding section there are six types of welding machines used in manufacturing of frames and body covers

1 Gantry System Gantry system is a system in which gantry crane is used for transporting the frame and welding is done by the robots and welding is finished by the robots the gantry crane picks up the frame and body covers and puts them on the conveyer or the hanger which goes to the weld body storage On gantry system seam welding is done on the body covers and on the frames with the help of the welding robots This system is fully automatic and there is no involvement of human being it picks up the frame and body covers from the location defined to it then does all the processing on it and then passes it to the conveyer

2 MIG Welding Metal inert gas welding in this inert gas argon is used and argon acts as a shielding gas 1-5 oxygen is used This type of welding uses consumable wire electrode during the welding process that is fed from the wire spool MIG welding has some advantages over the other welding techniques It provides a uniform weld it provides a slag free weld beam and needs little clean up

3 Spot Welding Spot welding is a process in which contacting metal surface are joined by the heat obtained from resistance to electric flow and this type of welding is done on the body covers of the scooter

4 Seam Welding It is a process that welds at a surface of overlapped parts along a length of a joint Weld made by overlapping nuggets this type of welding is done on the fuel tanks and mudguards of scooter

5 Portable Spot Welding It is a portable gun which can be taken to specified range where other spot welding machine faces difficulty in welding This type of the welding is done on body covers of scooters

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 39

6 Fine Boring Fine boring is done on the frame where handle has to fit after fine boring handle is attached to it

When various operation of the welding on the different components of the scooter that is frame mudguard body covers and fuel tank is over then this welded body parts are loaded on to a conveyer hanger which takes these body parts to the weld body storage and in the weld body storage and in weld body storage there are three sections one for model 1 one for model 2 and the last for model 3 When welded body is loaded on to a conveyor then the person who loads these bodies on to the hanger select in which model hanger has to go and the selection is done with a selector switch present Up to 300 hangers can be stored in the storage area that means around 600 frames and 600 body covers can be stored in the weld storage area From storage area hangers move to the unloading area and from unloading area these body covers and frames are loaded on to a Carrier which takes them to the paint section Unloading of the frames and body covers depends on the requirement of the assembly line and which model they are making according to their requirement unloading of model frames and body covers is done Unloading of the model is again done by the selector switch that is when there is requirement of model 1 the person who unloads the frame presses model switch and from storage model 1 moves to the unloading area Similarly when there is requirement of model 2 then operator presses model 2 switch and same goes for the model 3 when the requirement is of model 3 the operator presses the model 3 switch and then from storage model 3 moves to unloading bay

3 Top Coat

Loading In this process frames and body covers are mounted on the carrier of the conveyor line There are two lines for the paint that is paint A line and paint B line both the lines are very much important because in A line loading of frames and front body left right cover and rear body covers are loaded and on B line mudguard and front cowl is loaded and after loading of these parts then the carrier moves to the pretreatment zone

Pre-Treatment In pre-treatment degreasing and dust cleaning is done In pre-treatment bodies have to undergo two operations first wasting with the soft water by this process degreasing is done and all the dust particles are removed from the frames and body covers In general first we get hard water is converted to soft water by ion exchange mechanism

Secondly on bodies and frames phosphate cleaning is done by this method any dust particle or any grease particle left on the frames and body cover is removed

Electro-Deposition In electro deposition carrier which carries frame and body covers turn down into the electro deposition chamber and in electro deposition chamber is filled with the base paint or primer When carrier turns down it strikes high voltage wire and it gets negatively charged and become cathode and paint in the chamber becomes anode then a uniform thin film of base paint is deposited on

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 42

the body covers and frames of the scooter This process is repeated twice and after that it is passed to ED oven

ED Oven In electro deposition oven base coat done on the frame and body covers is heated to 150 degree temperature and this base coat is dried here and after that is passed to paint booth

Paint Booth Paint booth has three sections first one is sanding zone second primary coat or under coat and third is top coat

In sanding zone sanding of the frames and body covers is done and after that it is sent to under coat zone in under coat zone single coat of the paint is done on frames and body covers and in this zone coat of paint is done with the help of robots and after that frames and body covers then sent to top coat zone here in this zone second coat of the paint is done and this second coat of paint is done with the operator and after that these frames and body covers are sent to top coat oven

Top Coat Oven In top coat oven these frames and body covers are heated up to 170 degree temperature and dried and then allowed to cool naturally to room temperature and from there it is sent to the inspection zone

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 43

Inspection Zone In inspection zone body covers and frames have to pass infra-red zone Here IR testing machine checks for irregularities in the paint done and after that these body covers and frames are manually checked by hand for any errors in the paint jobs Parts which pass these tests get the OK mark and move to unloading area

Unloading In this area unloading of frames and body covers takes place Frames and body covers having OK mark are loaded to the paint body store and body covers and frames not having OK mark on them are sent to the repair work station and there they fix the problems which frames and body covers have They are then unloaded and then loaded on to the hanger and the parts go to the paint body storage In storage final or finished body covers and frames are stored which from storage area moves to the final assembly line

9 ProjectProject Definition

To study the various parts of the carrier being used in the paint shop and its problem analysis

Project Introduction

Carrier is defined as a thing which supports or holds up a part during its movement It is used to carry parts to the paint shop where various processes can be performed Carrier forms the basis of the Paint Shop because the movement of the parts from one point to another in the paint shop takes place only due to carrier The parts are loaded on the carrier with the help of a jig and then the motion takes place

Paint shop carrier is the most important moving part in the paint process Most problems and the breakdowns in the paint shop occur due to the carrier only It causes loss to the net production Bends or breaks due to load of body part applied on carrier causes distortions which ultimately results in the breakdown

Carrier is a part of the conveyer system being used in the paint shop The other components of the conveyer system are the prime mover drive (works as the input motion source for chain) chain and chain track carrier carrier turn (for turning the carrier) carrier

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 45

revolution (for revolving the carrier) stopper (it temporarily stops the carrier on line) carrier locks auto feeder cylinders and drop lifters which support the motion of carrier

Part Description Of Carrier

Rail

Rail can be of two types ie pre rail and power rail Pre rail is used to drive trolley of the carrier Power rail is used to drive the conveyer system

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 46

Gear Box

Gear Box acts as a Speed Reducer It consists of a worm and worm-wheel arrangement which turns the axis of rotation by 90deg and reduces the speed of the parts The gear box is coupled with the small sprocket Gear transmits power to small sprocket which helps for carrier turn this is also called as reduction gear The relation between the torque and diameter of worm shaft is given by

T (Kg-m) = π16dsup3τ

where τ is the twisting moment

Velocity Ratio = 160

Tensile Strength of Material = 60 Kgmmsup2

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 47

Trolley

There are two trolleys present in a carrier namely Front and the Rear Trolley Front Trolley stops the carrier at a specified position by the actuation of stopper while Rear Trolley stops the next carrier by engaging with the Front trolley of next carrier Trolley Wheel contains ball bearings The outer race serves as a wheel A grease fitting is installed as a greasing port Guide Roller is installed to reduce friction against free rail Pivoting Dog is lifted by the own weight The chain pusher engages to the Pivoting dog for transport To stop the carrier the stopper (installed on the line) pushes down the Pivoting Dog to release the engagement with the pusher

Swivel Pipe

Swivel pipe is used to drive carrier during carrier revolution Swivel pipe is connected to the shaft of worm gear thus it also gets its power from the gear box

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 48

Big Sprocket

Problem Analysis Of Carrier

Frame Hole NG

During the motion of the carrier when it is suddenly stopped by the stopper vibrations are produced in it and the pin inserted in the hole of the frame enlarges the size of the hole thereby causing the problem of frame hole NG

To reduce this problem an anti back-up system is applied to reduce the vibrations The NG frame hole is repaired by welding a bush at the site of the hole which is a newly developed Kaizen

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 64

Problems Caused By Loading

Improper loading of the frame body on the carrier damages the insulator collar because an unbalanced force acts upon it and insulator collars being the non-metallic parts are severely affected

R is the resultant vector

This is a production problem which causes the bending of jigs unbalancing of the carrier thereby causing improper motion at the carrier turns and revolutions and also resulting in the body parts falling in the oven

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 65

Gear Box Failure

Gear box of the carrier also fails some time due to overloading or improper coupling

Bending of Striker

Overloading at CTs and CRs causes the bending of the strikers which result in altered motion of the carrier

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 66

Breaking of Post

The post of the carrier can be broken due to variable and unbalanced load acting on the carrier The stresses are developed in the post which leads to its breaking Moreover hammering of the nut for the proper locking can also cause the breaking of nut

Overloading

Overloading is the state when the load on a part of the carrier is higher than its tolerance value Its causes are

If any object interrupts the motion of chain chain is not able to move forward properly causing overloading of chain

Improper position of the jig may lead to unbalancing of the carrier and overload may occur

Guide pin may not properly interact with the arm which may lead to non-alignment

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 67

Chain of the carrier turn may not be in proper position leading to overload at CT

Breaking of any of the carrier dogs will lead to improper revolution of the carrier

Other Problems

Cable breaks -gt Current does not reach to body part

ED COLLECTER burns out -gt It would not collect current

Threading of endndashplate striker wear out -gt Striker would not hit limit switch

Bush between coupling is cut

Bearing sometimes disrupts system

Swivel pipe bends -gt Carrier wouldnrsquot be leveled

Insulator sometimes fails to stop current

End plate threading wears

Spindle shaft bends -gt Carrier wouldnrsquot be leveled

Striker and arm also bends

Conclusion

From my project of one month here in HMSI I came to know that how

work goes on in the organization As far as my project of study

maintenance and breakdown analysis of carrier is concerned I came to

know the importance of carrier in paint shop and the production

problems caused by the carrier in the industry The carrier being used in

the paint shop is the best possible system for proper painting of parts

By knowing the various specifications problems related to it can be

solved

8 Introduction to Maintenance Department

Introduction The maintenance department is one of the most important departments of the organization where the organization has its own production Maintenance department of Honda Motorcycle and Scooter India Private Limited (HMSI) is a responsible for all the breakdowns which occur in the machines or where there is any production loss so when to overcome the problem of production loss maintenance team has to work efficiently so that there is no mistake committed by them by which production loss occurs

Some important definitions used by maintenance

Maintenance Action necessary for retaining or restoring an equipment machine or system to the specified operable condition to achieve its maximum useful life It includes planned and preventive maintenance

Planned Maintenance Preventive maintenance carried out according to a fixed plan is called planned maintenance

Preventive Maintenance Systematic inspection detection correction and prevention of incipient failures before they become actual or major failures is called as preventive maintenance

Breakdown Maintenance Repair or replacements performed after a machine has failed to return to its functional state following a malfunction or shutdown is called as breakdown maintenance

Predictive Maintenance Type of preventive maintenance performed continuously or at interval according to the requirement to diagnose and

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 36

monitor a condition or system also called condition based maintenance is called as predictive maintenance

Mean Time To Repair (MTTR) Basic measure of maintainability of repairable items it represents the average mean time required to repair a failed component or device is defined as mean time to repair

Mean Time Between Failures (MTBF) Basic measure of the reliability of repairable items it represents the average number of a life units during which all parts of a device or system perform within their specified limits under specified conditions are called as mean time between failures

Down Time Period during which an equipment or machine is not functional or cannot work It may be due to technical failures mechanical adjustments maintenance or non availability of inputs such as materials labor and power etc is called as down time

Frame Maintenance In this department there are three sections

1 Press Section

2 Weld Section

Engine Maintenance Frame Maintenance

3 Paint Section

PRESS SECTION Press section has mainly four machines

Komatsu Pressndash3

AIDA Press -1

CNC bending machine

Hind Press

These presses are mechanical presses and on this press mudguard fuel tank nose and body cover of the scooters like activa aviator dio shine twister unicorn and twister Process like blanking coining and bending of pipes is done

Blanking is cutting up a large sheer of stock into smaller pieces suitable for next operation

Coining is the process of removal of extra material or to make work piece up to the limit All these mechanical presses are of 500 ton and there only one hydraulic press and this press are used to repair the dyes

CNC pipe bending machines are used to bend the pipes which later used in the manufacturing of the frame

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 38

WELDING SECTION In welding section there are six types of welding machines used in manufacturing of frames and body covers

1 Gantry System Gantry system is a system in which gantry crane is used for transporting the frame and welding is done by the robots and welding is finished by the robots the gantry crane picks up the frame and body covers and puts them on the conveyer or the hanger which goes to the weld body storage On gantry system seam welding is done on the body covers and on the frames with the help of the welding robots This system is fully automatic and there is no involvement of human being it picks up the frame and body covers from the location defined to it then does all the processing on it and then passes it to the conveyer

2 MIG Welding Metal inert gas welding in this inert gas argon is used and argon acts as a shielding gas 1-5 oxygen is used This type of welding uses consumable wire electrode during the welding process that is fed from the wire spool MIG welding has some advantages over the other welding techniques It provides a uniform weld it provides a slag free weld beam and needs little clean up

3 Spot Welding Spot welding is a process in which contacting metal surface are joined by the heat obtained from resistance to electric flow and this type of welding is done on the body covers of the scooter

4 Seam Welding It is a process that welds at a surface of overlapped parts along a length of a joint Weld made by overlapping nuggets this type of welding is done on the fuel tanks and mudguards of scooter

5 Portable Spot Welding It is a portable gun which can be taken to specified range where other spot welding machine faces difficulty in welding This type of the welding is done on body covers of scooters

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 39

6 Fine Boring Fine boring is done on the frame where handle has to fit after fine boring handle is attached to it

When various operation of the welding on the different components of the scooter that is frame mudguard body covers and fuel tank is over then this welded body parts are loaded on to a conveyer hanger which takes these body parts to the weld body storage and in the weld body storage and in weld body storage there are three sections one for model 1 one for model 2 and the last for model 3 When welded body is loaded on to a conveyor then the person who loads these bodies on to the hanger select in which model hanger has to go and the selection is done with a selector switch present Up to 300 hangers can be stored in the storage area that means around 600 frames and 600 body covers can be stored in the weld storage area From storage area hangers move to the unloading area and from unloading area these body covers and frames are loaded on to a Carrier which takes them to the paint section Unloading of the frames and body covers depends on the requirement of the assembly line and which model they are making according to their requirement unloading of model frames and body covers is done Unloading of the model is again done by the selector switch that is when there is requirement of model 1 the person who unloads the frame presses model switch and from storage model 1 moves to the unloading area Similarly when there is requirement of model 2 then operator presses model 2 switch and same goes for the model 3 when the requirement is of model 3 the operator presses the model 3 switch and then from storage model 3 moves to unloading bay

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 41

1 Sanding Zone

2 Under Coat

3 Top Coat

Loading In this process frames and body covers are mounted on the carrier of the conveyor line There are two lines for the paint that is paint A line and paint B line both the lines are very much important because in A line loading of frames and front body left right cover and rear body covers are loaded and on B line mudguard and front cowl is loaded and after loading of these parts then the carrier moves to the pretreatment zone

Pre-Treatment In pre-treatment degreasing and dust cleaning is done In pre-treatment bodies have to undergo two operations first wasting with the soft water by this process degreasing is done and all the dust particles are removed from the frames and body covers In general first we get hard water is converted to soft water by ion exchange mechanism

Secondly on bodies and frames phosphate cleaning is done by this method any dust particle or any grease particle left on the frames and body cover is removed

Electro-Deposition In electro deposition carrier which carries frame and body covers turn down into the electro deposition chamber and in electro deposition chamber is filled with the base paint or primer When carrier turns down it strikes high voltage wire and it gets negatively charged and become cathode and paint in the chamber becomes anode then a uniform thin film of base paint is deposited on

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 42

the body covers and frames of the scooter This process is repeated twice and after that it is passed to ED oven

ED Oven In electro deposition oven base coat done on the frame and body covers is heated to 150 degree temperature and this base coat is dried here and after that is passed to paint booth

Paint Booth Paint booth has three sections first one is sanding zone second primary coat or under coat and third is top coat

In sanding zone sanding of the frames and body covers is done and after that it is sent to under coat zone in under coat zone single coat of the paint is done on frames and body covers and in this zone coat of paint is done with the help of robots and after that frames and body covers then sent to top coat zone here in this zone second coat of the paint is done and this second coat of paint is done with the operator and after that these frames and body covers are sent to top coat oven

Top Coat Oven In top coat oven these frames and body covers are heated up to 170 degree temperature and dried and then allowed to cool naturally to room temperature and from there it is sent to the inspection zone

Inspection Zone In inspection zone body covers and frames have to pass infra-red zone Here IR testing machine checks for irregularities in the paint done and after that these body covers and frames are manually checked by hand for any errors in the paint jobs Parts which pass these tests get the OK mark and move to unloading area

Unloading In this area unloading of frames and body covers takes place Frames and body covers having OK mark are loaded to the paint body store and body covers and frames not having OK mark on them are sent to the repair work station and there they fix the problems which frames and body covers have They are then unloaded and then loaded on to the hanger and the parts go to the paint body storage In storage final or finished body covers and frames are stored which from storage area moves to the final assembly line

9 ProjectProject Definition

To study the various parts of the carrier being used in the paint shop and its problem analysis

Project Introduction

Carrier is defined as a thing which supports or holds up a part during its movement It is used to carry parts to the paint shop where various processes can be performed Carrier forms the basis of the Paint Shop because the movement of the parts from one point to another in the paint shop takes place only due to carrier The parts are loaded on the carrier with the help of a jig and then the motion takes place

Paint shop carrier is the most important moving part in the paint process Most problems and the breakdowns in the paint shop occur due to the carrier only It causes loss to the net production Bends or breaks due to load of body part applied on carrier causes distortions which ultimately results in the breakdown

Carrier is a part of the conveyer system being used in the paint shop The other components of the conveyer system are the prime mover drive (works as the input motion source for chain) chain and chain track carrier carrier turn (for turning the carrier) carrier

revolution (for revolving the carrier) stopper (it temporarily stops the carrier on line) carrier locks auto feeder cylinders and drop lifters which support the motion of carrier

Part Description Of Carrier

Rail

Rail can be of two types ie pre rail and power rail Pre rail is used to drive trolley of the carrier Power rail is used to drive the conveyer system

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 46

Gear Box

Gear Box acts as a Speed Reducer It consists of a worm and worm-wheel arrangement which turns the axis of rotation by 90deg and reduces the speed of the parts The gear box is coupled with the small sprocket Gear transmits power to small sprocket which helps for carrier turn this is also called as reduction gear The relation between the torque and diameter of worm shaft is given by

T (Kg-m) = π16dsup3τ

where τ is the twisting moment

Velocity Ratio = 160

Tensile Strength of Material = 60 Kgmmsup2

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 47

Trolley

There are two trolleys present in a carrier namely Front and the Rear Trolley Front Trolley stops the carrier at a specified position by the actuation of stopper while Rear Trolley stops the next carrier by engaging with the Front trolley of next carrier Trolley Wheel contains ball bearings The outer race serves as a wheel A grease fitting is installed as a greasing port Guide Roller is installed to reduce friction against free rail Pivoting Dog is lifted by the own weight The chain pusher engages to the Pivoting dog for transport To stop the carrier the stopper (installed on the line) pushes down the Pivoting Dog to release the engagement with the pusher

Swivel Pipe

Swivel pipe is used to drive carrier during carrier revolution Swivel pipe is connected to the shaft of worm gear thus it also gets its power from the gear box

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 48

Big Sprocket

It comes in contact with the chain of the carrier turn and is responsible for rotation of the carrier It is mounted on the spindle on which the pan cover is fixed Four carrier dogs are attached to it which control the rotation of the carrier Big sprocket is attached to the spindle shaft plate

Small Sprocket

It is attached to the shaft connected to gear box It comes in contact with the chain of carrier revolution and is responsible for the revolution of the carrier

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 49

Tension Spring

Spring is used to lock turning plate thus stopping carrier revolution It happens when there is no load on the spring But when the load is applied turning plate opens and hence carrier revolution occurs

Insulator Collar

It provides insulation to the carrier in ED process so that there is no current in the frame To avoid the flow of current in the rail of the conveyer system and to avoid damage to the whole system insulator collars are provided

Post

It is mounted on the pan cover and holds the jig by locking it at its position Post mainly has three parts post cover post spacer and post spacer

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 50

Coupling

Bush Coupling transfers the motion from small sprocket shaft to input shaft To avoid overloading at the gear box bush coupling is provided

Guide Pin Arm

It locks the turning of the Big Sprocket by elongating the spring connected to it It has three contact points one is the spring one touches the guide pin of the carrier turn and third is for the engagement and disengagement of big sprocket

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 51

ED Collector

ED collector is used to collect current during ED process and transmits it through the cables to the body parts

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 52

End Striker amp Turn Striker

They are used to control the turning and revolution of the carrier respectively While end striker controls the revolution of the carrier turn striker controls the rotation of the carrier

Pan Cover

Problem Analysis Of Carrier

Frame Hole NG

During the motion of the carrier when it is suddenly stopped by the stopper vibrations are produced in it and the pin inserted in the hole of the frame enlarges the size of the hole thereby causing the problem of frame hole NG

To reduce this problem an anti back-up system is applied to reduce the vibrations The NG frame hole is repaired by welding a bush at the site of the hole which is a newly developed Kaizen

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 64

Problems Caused By Loading

Improper loading of the frame body on the carrier damages the insulator collar because an unbalanced force acts upon it and insulator collars being the non-metallic parts are severely affected

R is the resultant vector

This is a production problem which causes the bending of jigs unbalancing of the carrier thereby causing improper motion at the carrier turns and revolutions and also resulting in the body parts falling in the oven

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 65

Gear Box Failure

Gear box of the carrier also fails some time due to overloading or improper coupling

Bending of Striker

Overloading at CTs and CRs causes the bending of the strikers which result in altered motion of the carrier

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 66

Breaking of Post

The post of the carrier can be broken due to variable and unbalanced load acting on the carrier The stresses are developed in the post which leads to its breaking Moreover hammering of the nut for the proper locking can also cause the breaking of nut

Overloading

Overloading is the state when the load on a part of the carrier is higher than its tolerance value Its causes are

If any object interrupts the motion of chain chain is not able to move forward properly causing overloading of chain

Improper position of the jig may lead to unbalancing of the carrier and overload may occur

Guide pin may not properly interact with the arm which may lead to non-alignment

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 67

Chain of the carrier turn may not be in proper position leading to overload at CT

Breaking of any of the carrier dogs will lead to improper revolution of the carrier

Other Problems

Cable breaks -gt Current does not reach to body part

ED COLLECTER burns out -gt It would not collect current

Threading of endndashplate striker wear out -gt Striker would not hit limit switch

Bush between coupling is cut

Bearing sometimes disrupts system

Swivel pipe bends -gt Carrier wouldnrsquot be leveled

Insulator sometimes fails to stop current

End plate threading wears

Spindle shaft bends -gt Carrier wouldnrsquot be leveled

Striker and arm also bends

11 HONDA HISTORY

FOUNDER - SOICHIRO HONDA ESTABLISHED AT - HAMAMATSU (JAPAN) ON 24 TH SEP 1948

MR HONDA helliphelliphellip A MAN AND HIS DREAM

He dreamed of providing people everywhere in the world an economical means of transportation He thought of better ways of making piston rings and found a company amp began production Then his company started producing small motorcycles including one built in 1949 called D-type dream

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 6

Then he thought of making high capacity motorcycles and taking them to racing So his company made bigger and faster machines two- four- five- and six-cylinder race bikes and participated in the Isle of Man TT race (125 cc motorcycle class)

He wanted to share his new motorcycles with the world and therefore he opened American Honda Motor Co in Los Angeles Also Honda began manufacturing motorcycles at its Suzuka factory in 1960 Honda launched its first sports car the S500 in Japan and entered Formula-1 in 1964

In 1989 Soichiro Honda became the first Asian to be inducted into US Automotive Hall of Fame In 1990 Honda wins its fifth consecutive 1st ranking in the JD Power Consumer Satisfaction Index In 1993 founder Soichiro Honda passed away He dreamed of changing the way people looked at motorcycles and gave us machines that were powerful amp fun to ride SOICHIRO HONDArsquoS dreams changed the world of motorcycling

8 Introduction to Maintenance Department

Introduction The maintenance department is one of the most important departments of the organization where the organization has its own production Maintenance department of Honda Motorcycle and Scooter India Private Limited (HMSI) is a responsible for all the breakdowns which occur in the machines or where there is any production loss so when to overcome the problem of production loss maintenance team has to work efficiently so that there is no mistake committed by them by which production loss occurs

Some important definitions used by maintenance

Maintenance Action necessary for retaining or restoring an equipment machine or system to the specified operable condition to achieve its maximum useful life It includes planned and preventive maintenance

Planned Maintenance Preventive maintenance carried out according to a fixed plan is called planned maintenance

Preventive Maintenance Systematic inspection detection correction and prevention of incipient failures before they become actual or major failures is called as preventive maintenance

Breakdown Maintenance Repair or replacements performed after a machine has failed to return to its functional state following a malfunction or shutdown is called as breakdown maintenance

Predictive Maintenance Type of preventive maintenance performed continuously or at interval according to the requirement to diagnose and

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 36

monitor a condition or system also called condition based maintenance is called as predictive maintenance

Mean Time To Repair (MTTR) Basic measure of maintainability of repairable items it represents the average mean time required to repair a failed component or device is defined as mean time to repair

Mean Time Between Failures (MTBF) Basic measure of the reliability of repairable items it represents the average number of a life units during which all parts of a device or system perform within their specified limits under specified conditions are called as mean time between failures

Down Time Period during which an equipment or machine is not functional or cannot work It may be due to technical failures mechanical adjustments maintenance or non availability of inputs such as materials labor and power etc is called as down time

Frame Maintenance In this department there are three sections

1 Press Section

2 Weld Section

3 Paint Section

PRESS SECTION Press section has mainly four machines

Komatsu Pressndash3

AIDA Press -1

CNC bending machine

Hind Press

These presses are mechanical presses and on this press mudguard fuel tank nose and body cover of the scooters like activa aviator dio shine twister unicorn and twister Process like blanking coining and bending of pipes is done

Blanking is cutting up a large sheer of stock into smaller pieces suitable for next operation

Coining is the process of removal of extra material or to make work piece up to the limit All these mechanical presses are of 500 ton and there only one hydraulic press and this press are used to repair the dyes

CNC pipe bending machines are used to bend the pipes which later used in the manufacturing of the frame

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 38

WELDING SECTION In welding section there are six types of welding machines used in manufacturing of frames and body covers

1 Gantry System Gantry system is a system in which gantry crane is used for transporting the frame and welding is done by the robots and welding is finished by the robots the gantry crane picks up the frame and body covers and puts them on the conveyer or the hanger which goes to the weld body storage On gantry system seam welding is done on the body covers and on the frames with the help of the welding robots This system is fully automatic and there is no involvement of human being it picks up the frame and body covers from the location defined to it then does all the processing on it and then passes it to the conveyer

2 MIG Welding Metal inert gas welding in this inert gas argon is used and argon acts as a shielding gas 1-5 oxygen is used This type of welding uses consumable wire electrode during the welding process that is fed from the wire spool MIG welding has some advantages over the other welding techniques It provides a uniform weld it provides a slag free weld beam and needs little clean up

3 Spot Welding Spot welding is a process in which contacting metal surface are joined by the heat obtained from resistance to electric flow and this type of welding is done on the body covers of the scooter

4 Seam Welding It is a process that welds at a surface of overlapped parts along a length of a joint Weld made by overlapping nuggets this type of welding is done on the fuel tanks and mudguards of scooter

5 Portable Spot Welding It is a portable gun which can be taken to specified range where other spot welding machine faces difficulty in welding This type of the welding is done on body covers of scooters

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 39

6 Fine Boring Fine boring is done on the frame where handle has to fit after fine boring handle is attached to it

When various operation of the welding on the different components of the scooter that is frame mudguard body covers and fuel tank is over then this welded body parts are loaded on to a conveyer hanger which takes these body parts to the weld body storage and in the weld body storage and in weld body storage there are three sections one for model 1 one for model 2 and the last for model 3 When welded body is loaded on to a conveyor then the person who loads these bodies on to the hanger select in which model hanger has to go and the selection is done with a selector switch present Up to 300 hangers can be stored in the storage area that means around 600 frames and 600 body covers can be stored in the weld storage area From storage area hangers move to the unloading area and from unloading area these body covers and frames are loaded on to a Carrier which takes them to the paint section Unloading of the frames and body covers depends on the requirement of the assembly line and which model they are making according to their requirement unloading of model frames and body covers is done Unloading of the model is again done by the selector switch that is when there is requirement of model 1 the person who unloads the frame presses model switch and from storage model 1 moves to the unloading area Similarly when there is requirement of model 2 then operator presses model 2 switch and same goes for the model 3 when the requirement is of model 3 the operator presses the model 3 switch and then from storage model 3 moves to unloading bay

PAINT SECTION Paint section is very important section In this section different treatments are done on the body covers and frames and it is a step by step process done as follows

Loading

Pre-Treatment

Electro-Deposition

ED Oven

Booth

Top Coat Oven

Inspection Zone

Unloading

PAINT PROCESS FLOW

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 41

1 Sanding Zone

2 Under Coat

3 Top Coat

Loading In this process frames and body covers are mounted on the carrier of the conveyor line There are two lines for the paint that is paint A line and paint B line both the lines are very much important because in A line loading of frames and front body left right cover and rear body covers are loaded and on B line mudguard and front cowl is loaded and after loading of these parts then the carrier moves to the pretreatment zone

Pre-Treatment In pre-treatment degreasing and dust cleaning is done In pre-treatment bodies have to undergo two operations first wasting with the soft water by this process degreasing is done and all the dust particles are removed from the frames and body covers In general first we get hard water is converted to soft water by ion exchange mechanism

Secondly on bodies and frames phosphate cleaning is done by this method any dust particle or any grease particle left on the frames and body cover is removed

Electro-Deposition In electro deposition carrier which carries frame and body covers turn down into the electro deposition chamber and in electro deposition chamber is filled with the base paint or primer When carrier turns down it strikes high voltage wire and it gets negatively charged and become cathode and paint in the chamber becomes anode then a uniform thin film of base paint is deposited on

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 42

the body covers and frames of the scooter This process is repeated twice and after that it is passed to ED oven

ED Oven In electro deposition oven base coat done on the frame and body covers is heated to 150 degree temperature and this base coat is dried here and after that is passed to paint booth

Paint Booth Paint booth has three sections first one is sanding zone second primary coat or under coat and third is top coat

In sanding zone sanding of the frames and body covers is done and after that it is sent to under coat zone in under coat zone single coat of the paint is done on frames and body covers and in this zone coat of paint is done with the help of robots and after that frames and body covers then sent to top coat zone here in this zone second coat of the paint is done and this second coat of paint is done with the operator and after that these frames and body covers are sent to top coat oven

Top Coat Oven In top coat oven these frames and body covers are heated up to 170 degree temperature and dried and then allowed to cool naturally to room temperature and from there it is sent to the inspection zone

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 43

Inspection Zone In inspection zone body covers and frames have to pass infra-red zone Here IR testing machine checks for irregularities in the paint done and after that these body covers and frames are manually checked by hand for any errors in the paint jobs Parts which pass these tests get the OK mark and move to unloading area

Unloading In this area unloading of frames and body covers takes place Frames and body covers having OK mark are loaded to the paint body store and body covers and frames not having OK mark on them are sent to the repair work station and there they fix the problems which frames and body covers have They are then unloaded and then loaded on to the hanger and the parts go to the paint body storage In storage final or finished body covers and frames are stored which from storage area moves to the final assembly line

9 ProjectProject Definition

To study the various parts of the carrier being used in the paint shop and its problem analysis

Project Introduction

Carrier is defined as a thing which supports or holds up a part during its movement It is used to carry parts to the paint shop where various processes can be performed Carrier forms the basis of the Paint Shop because the movement of the parts from one point to another in the paint shop takes place only due to carrier The parts are loaded on the carrier with the help of a jig and then the motion takes place

Paint shop carrier is the most important moving part in the paint process Most problems and the breakdowns in the paint shop occur due to the carrier only It causes loss to the net production Bends or breaks due to load of body part applied on carrier causes distortions which ultimately results in the breakdown

Carrier is a part of the conveyer system being used in the paint shop The other components of the conveyer system are the prime mover drive (works as the input motion source for chain) chain and chain track carrier carrier turn (for turning the carrier) carrier

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 45

revolution (for revolving the carrier) stopper (it temporarily stops the carrier on line) carrier locks auto feeder cylinders and drop lifters which support the motion of carrier

Part Description Of Carrier

Rail

Rail can be of two types ie pre rail and power rail Pre rail is used to drive trolley of the carrier Power rail is used to drive the conveyer system

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 46

Gear Box

Gear Box acts as a Speed Reducer It consists of a worm and worm-wheel arrangement which turns the axis of rotation by 90deg and reduces the speed of the parts The gear box is coupled with the small sprocket Gear transmits power to small sprocket which helps for carrier turn this is also called as reduction gear The relation between the torque and diameter of worm shaft is given by

T (Kg-m) = π16dsup3τ

where τ is the twisting moment

Problem Analysis Of Carrier

Frame Hole NG

During the motion of the carrier when it is suddenly stopped by the stopper vibrations are produced in it and the pin inserted in the hole of the frame enlarges the size of the hole thereby causing the problem of frame hole NG

To reduce this problem an anti back-up system is applied to reduce the vibrations The NG frame hole is repaired by welding a bush at the site of the hole which is a newly developed Kaizen

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 64

Problems Caused By Loading

Improper loading of the frame body on the carrier damages the insulator collar because an unbalanced force acts upon it and insulator collars being the non-metallic parts are severely affected

R is the resultant vector

This is a production problem which causes the bending of jigs unbalancing of the carrier thereby causing improper motion at the carrier turns and revolutions and also resulting in the body parts falling in the oven

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 65

Gear Box Failure

Gear box of the carrier also fails some time due to overloading or improper coupling

Bending of Striker

Overloading at CTs and CRs causes the bending of the strikers which result in altered motion of the carrier

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 66

Breaking of Post

The post of the carrier can be broken due to variable and unbalanced load acting on the carrier The stresses are developed in the post which leads to its breaking Moreover hammering of the nut for the proper locking can also cause the breaking of nut

Overloading

Overloading is the state when the load on a part of the carrier is higher than its tolerance value Its causes are

If any object interrupts the motion of chain chain is not able to move forward properly causing overloading of chain

Improper position of the jig may lead to unbalancing of the carrier and overload may occur

Guide pin may not properly interact with the arm which may lead to non-alignment

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 67

Chain of the carrier turn may not be in proper position leading to overload at CT

Breaking of any of the carrier dogs will lead to improper revolution of the carrier

Other Problems

Cable breaks -gt Current does not reach to body part

ED COLLECTER burns out -gt It would not collect current

Threading of endndashplate striker wear out -gt Striker would not hit limit switch

Bush between coupling is cut

Bearing sometimes disrupts system

Swivel pipe bends -gt Carrier wouldnrsquot be leveled

Insulator sometimes fails to stop current

End plate threading wears

Spindle shaft bends -gt Carrier wouldnrsquot be leveled

Striker and arm also bends

FOUNDER - SOICHIRO HONDA ESTABLISHED AT - HAMAMATSU (JAPAN) ON 24 TH SEP 1948

MR HONDA helliphelliphellip A MAN AND HIS DREAM

He dreamed of providing people everywhere in the world an economical means of transportation He thought of better ways of making piston rings and found a company amp began production Then his company started producing small motorcycles including one built in 1949 called D-type dream

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 6

Then he thought of making high capacity motorcycles and taking them to racing So his company made bigger and faster machines two- four- five- and six-cylinder race bikes and participated in the Isle of Man TT race (125 cc motorcycle class)

He wanted to share his new motorcycles with the world and therefore he opened American Honda Motor Co in Los Angeles Also Honda began manufacturing motorcycles at its Suzuka factory in 1960 Honda launched its first sports car the S500 in Japan and entered Formula-1 in 1964

In 1989 Soichiro Honda became the first Asian to be inducted into US Automotive Hall of Fame In 1990 Honda wins its fifth consecutive 1st ranking in the JD Power Consumer Satisfaction Index In 1993 founder Soichiro Honda passed away He dreamed of changing the way people looked at motorcycles and gave us machines that were powerful amp fun to ride SOICHIRO HONDArsquoS dreams changed the world of motorcycling

8 Introduction to Maintenance Department

Introduction The maintenance department is one of the most important departments of the organization where the organization has its own production Maintenance department of Honda Motorcycle and Scooter India Private Limited (HMSI) is a responsible for all the breakdowns which occur in the machines or where there is any production loss so when to overcome the problem of production loss maintenance team has to work efficiently so that there is no mistake committed by them by which production loss occurs

Some important definitions used by maintenance

Maintenance Action necessary for retaining or restoring an equipment machine or system to the specified operable condition to achieve its maximum useful life It includes planned and preventive maintenance

Planned Maintenance Preventive maintenance carried out according to a fixed plan is called planned maintenance

Preventive Maintenance Systematic inspection detection correction and prevention of incipient failures before they become actual or major failures is called as preventive maintenance

Breakdown Maintenance Repair or replacements performed after a machine has failed to return to its functional state following a malfunction or shutdown is called as breakdown maintenance

Predictive Maintenance Type of preventive maintenance performed continuously or at interval according to the requirement to diagnose and

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 36

monitor a condition or system also called condition based maintenance is called as predictive maintenance

Mean Time To Repair (MTTR) Basic measure of maintainability of repairable items it represents the average mean time required to repair a failed component or device is defined as mean time to repair

Mean Time Between Failures (MTBF) Basic measure of the reliability of repairable items it represents the average number of a life units during which all parts of a device or system perform within their specified limits under specified conditions are called as mean time between failures

Down Time Period during which an equipment or machine is not functional or cannot work It may be due to technical failures mechanical adjustments maintenance or non availability of inputs such as materials labor and power etc is called as down time

Frame Maintenance In this department there are three sections

1 Press Section

2 Weld Section

3 Paint Section

PRESS SECTION Press section has mainly four machines

Komatsu Pressndash3

AIDA Press -1

CNC bending machine

Hind Press

These presses are mechanical presses and on this press mudguard fuel tank nose and body cover of the scooters like activa aviator dio shine twister unicorn and twister Process like blanking coining and bending of pipes is done

Blanking is cutting up a large sheer of stock into smaller pieces suitable for next operation

Coining is the process of removal of extra material or to make work piece up to the limit All these mechanical presses are of 500 ton and there only one hydraulic press and this press are used to repair the dyes

CNC pipe bending machines are used to bend the pipes which later used in the manufacturing of the frame

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 38

WELDING SECTION In welding section there are six types of welding machines used in manufacturing of frames and body covers

1 Gantry System Gantry system is a system in which gantry crane is used for transporting the frame and welding is done by the robots and welding is finished by the robots the gantry crane picks up the frame and body covers and puts them on the conveyer or the hanger which goes to the weld body storage On gantry system seam welding is done on the body covers and on the frames with the help of the welding robots This system is fully automatic and there is no involvement of human being it picks up the frame and body covers from the location defined to it then does all the processing on it and then passes it to the conveyer

2 MIG Welding Metal inert gas welding in this inert gas argon is used and argon acts as a shielding gas 1-5 oxygen is used This type of welding uses consumable wire electrode during the welding process that is fed from the wire spool MIG welding has some advantages over the other welding techniques It provides a uniform weld it provides a slag free weld beam and needs little clean up

3 Spot Welding Spot welding is a process in which contacting metal surface are joined by the heat obtained from resistance to electric flow and this type of welding is done on the body covers of the scooter

4 Seam Welding It is a process that welds at a surface of overlapped parts along a length of a joint Weld made by overlapping nuggets this type of welding is done on the fuel tanks and mudguards of scooter

5 Portable Spot Welding It is a portable gun which can be taken to specified range where other spot welding machine faces difficulty in welding This type of the welding is done on body covers of scooters

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 39

6 Fine Boring Fine boring is done on the frame where handle has to fit after fine boring handle is attached to it

When various operation of the welding on the different components of the scooter that is frame mudguard body covers and fuel tank is over then this welded body parts are loaded on to a conveyer hanger which takes these body parts to the weld body storage and in the weld body storage and in weld body storage there are three sections one for model 1 one for model 2 and the last for model 3 When welded body is loaded on to a conveyor then the person who loads these bodies on to the hanger select in which model hanger has to go and the selection is done with a selector switch present Up to 300 hangers can be stored in the storage area that means around 600 frames and 600 body covers can be stored in the weld storage area From storage area hangers move to the unloading area and from unloading area these body covers and frames are loaded on to a Carrier which takes them to the paint section Unloading of the frames and body covers depends on the requirement of the assembly line and which model they are making according to their requirement unloading of model frames and body covers is done Unloading of the model is again done by the selector switch that is when there is requirement of model 1 the person who unloads the frame presses model switch and from storage model 1 moves to the unloading area Similarly when there is requirement of model 2 then operator presses model 2 switch and same goes for the model 3 when the requirement is of model 3 the operator presses the model 3 switch and then from storage model 3 moves to unloading bay

1 Sanding Zone

2 Under Coat

3 Top Coat

Loading In this process frames and body covers are mounted on the carrier of the conveyor line There are two lines for the paint that is paint A line and paint B line both the lines are very much important because in A line loading of frames and front body left right cover and rear body covers are loaded and on B line mudguard and front cowl is loaded and after loading of these parts then the carrier moves to the pretreatment zone

Pre-Treatment In pre-treatment degreasing and dust cleaning is done In pre-treatment bodies have to undergo two operations first wasting with the soft water by this process degreasing is done and all the dust particles are removed from the frames and body covers In general first we get hard water is converted to soft water by ion exchange mechanism

Secondly on bodies and frames phosphate cleaning is done by this method any dust particle or any grease particle left on the frames and body cover is removed

Electro-Deposition In electro deposition carrier which carries frame and body covers turn down into the electro deposition chamber and in electro deposition chamber is filled with the base paint or primer When carrier turns down it strikes high voltage wire and it gets negatively charged and become cathode and paint in the chamber becomes anode then a uniform thin film of base paint is deposited on

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 42

the body covers and frames of the scooter This process is repeated twice and after that it is passed to ED oven

ED Oven In electro deposition oven base coat done on the frame and body covers is heated to 150 degree temperature and this base coat is dried here and after that is passed to paint booth

Paint Booth Paint booth has three sections first one is sanding zone second primary coat or under coat and third is top coat

In sanding zone sanding of the frames and body covers is done and after that it is sent to under coat zone in under coat zone single coat of the paint is done on frames and body covers and in this zone coat of paint is done with the help of robots and after that frames and body covers then sent to top coat zone here in this zone second coat of the paint is done and this second coat of paint is done with the operator and after that these frames and body covers are sent to top coat oven

Top Coat Oven In top coat oven these frames and body covers are heated up to 170 degree temperature and dried and then allowed to cool naturally to room temperature and from there it is sent to the inspection zone

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 43

Inspection Zone In inspection zone body covers and frames have to pass infra-red zone Here IR testing machine checks for irregularities in the paint done and after that these body covers and frames are manually checked by hand for any errors in the paint jobs Parts which pass these tests get the OK mark and move to unloading area

Unloading In this area unloading of frames and body covers takes place Frames and body covers having OK mark are loaded to the paint body store and body covers and frames not having OK mark on them are sent to the repair work station and there they fix the problems which frames and body covers have They are then unloaded and then loaded on to the hanger and the parts go to the paint body storage In storage final or finished body covers and frames are stored which from storage area moves to the final assembly line

9 ProjectProject Definition

To study the various parts of the carrier being used in the paint shop and its problem analysis

Project Introduction

Carrier is defined as a thing which supports or holds up a part during its movement It is used to carry parts to the paint shop where various processes can be performed Carrier forms the basis of the Paint Shop because the movement of the parts from one point to another in the paint shop takes place only due to carrier The parts are loaded on the carrier with the help of a jig and then the motion takes place

Paint shop carrier is the most important moving part in the paint process Most problems and the breakdowns in the paint shop occur due to the carrier only It causes loss to the net production Bends or breaks due to load of body part applied on carrier causes distortions which ultimately results in the breakdown

Carrier is a part of the conveyer system being used in the paint shop The other components of the conveyer system are the prime mover drive (works as the input motion source for chain) chain and chain track carrier carrier turn (for turning the carrier) carrier

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 45

revolution (for revolving the carrier) stopper (it temporarily stops the carrier on line) carrier locks auto feeder cylinders and drop lifters which support the motion of carrier

Part Description Of Carrier

Rail

Rail can be of two types ie pre rail and power rail Pre rail is used to drive trolley of the carrier Power rail is used to drive the conveyer system

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 46

Gear Box

Gear Box acts as a Speed Reducer It consists of a worm and worm-wheel arrangement which turns the axis of rotation by 90deg and reduces the speed of the parts The gear box is coupled with the small sprocket Gear transmits power to small sprocket which helps for carrier turn this is also called as reduction gear The relation between the torque and diameter of worm shaft is given by

T (Kg-m) = π16dsup3τ

where τ is the twisting moment

Velocity Ratio = 160

Tensile Strength of Material = 60 Kgmmsup2

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 47

Trolley

There are two trolleys present in a carrier namely Front and the Rear Trolley Front Trolley stops the carrier at a specified position by the actuation of stopper while Rear Trolley stops the next carrier by engaging with the Front trolley of next carrier Trolley Wheel contains ball bearings The outer race serves as a wheel A grease fitting is installed as a greasing port Guide Roller is installed to reduce friction against free rail Pivoting Dog is lifted by the own weight The chain pusher engages to the Pivoting dog for transport To stop the carrier the stopper (installed on the line) pushes down the Pivoting Dog to release the engagement with the pusher

Swivel Pipe

Swivel pipe is used to drive carrier during carrier revolution Swivel pipe is connected to the shaft of worm gear thus it also gets its power from the gear box

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 48

Problem Analysis Of Carrier

Frame Hole NG

During the motion of the carrier when it is suddenly stopped by the stopper vibrations are produced in it and the pin inserted in the hole of the frame enlarges the size of the hole thereby causing the problem of frame hole NG

To reduce this problem an anti back-up system is applied to reduce the vibrations The NG frame hole is repaired by welding a bush at the site of the hole which is a newly developed Kaizen

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 64

Problems Caused By Loading

Improper loading of the frame body on the carrier damages the insulator collar because an unbalanced force acts upon it and insulator collars being the non-metallic parts are severely affected

R is the resultant vector

This is a production problem which causes the bending of jigs unbalancing of the carrier thereby causing improper motion at the carrier turns and revolutions and also resulting in the body parts falling in the oven

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 65

Gear Box Failure

Gear box of the carrier also fails some time due to overloading or improper coupling

Bending of Striker

Overloading at CTs and CRs causes the bending of the strikers which result in altered motion of the carrier

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 66

Breaking of Post

The post of the carrier can be broken due to variable and unbalanced load acting on the carrier The stresses are developed in the post which leads to its breaking Moreover hammering of the nut for the proper locking can also cause the breaking of nut

Overloading

Overloading is the state when the load on a part of the carrier is higher than its tolerance value Its causes are

If any object interrupts the motion of chain chain is not able to move forward properly causing overloading of chain

Improper position of the jig may lead to unbalancing of the carrier and overload may occur

Guide pin may not properly interact with the arm which may lead to non-alignment

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 67

Chain of the carrier turn may not be in proper position leading to overload at CT

Breaking of any of the carrier dogs will lead to improper revolution of the carrier

Other Problems

Cable breaks -gt Current does not reach to body part

ED COLLECTER burns out -gt It would not collect current

Threading of endndashplate striker wear out -gt Striker would not hit limit switch

Bush between coupling is cut

Bearing sometimes disrupts system

Swivel pipe bends -gt Carrier wouldnrsquot be leveled

Insulator sometimes fails to stop current

End plate threading wears

Spindle shaft bends -gt Carrier wouldnrsquot be leveled

Striker and arm also bends

8 Introduction to Maintenance Department

Introduction The maintenance department is one of the most important departments of the organization where the organization has its own production Maintenance department of Honda Motorcycle and Scooter India Private Limited (HMSI) is a responsible for all the breakdowns which occur in the machines or where there is any production loss so when to overcome the problem of production loss maintenance team has to work efficiently so that there is no mistake committed by them by which production loss occurs

Some important definitions used by maintenance

Maintenance Action necessary for retaining or restoring an equipment machine or system to the specified operable condition to achieve its maximum useful life It includes planned and preventive maintenance

Planned Maintenance Preventive maintenance carried out according to a fixed plan is called planned maintenance

Preventive Maintenance Systematic inspection detection correction and prevention of incipient failures before they become actual or major failures is called as preventive maintenance

Breakdown Maintenance Repair or replacements performed after a machine has failed to return to its functional state following a malfunction or shutdown is called as breakdown maintenance

Predictive Maintenance Type of preventive maintenance performed continuously or at interval according to the requirement to diagnose and

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 36

monitor a condition or system also called condition based maintenance is called as predictive maintenance

Mean Time To Repair (MTTR) Basic measure of maintainability of repairable items it represents the average mean time required to repair a failed component or device is defined as mean time to repair

Mean Time Between Failures (MTBF) Basic measure of the reliability of repairable items it represents the average number of a life units during which all parts of a device or system perform within their specified limits under specified conditions are called as mean time between failures

Down Time Period during which an equipment or machine is not functional or cannot work It may be due to technical failures mechanical adjustments maintenance or non availability of inputs such as materials labor and power etc is called as down time

Frame Maintenance In this department there are three sections

1 Press Section

2 Weld Section

3 Paint Section

PRESS SECTION Press section has mainly four machines

Komatsu Pressndash3

AIDA Press -1

CNC bending machine

Hind Press

These presses are mechanical presses and on this press mudguard fuel tank nose and body cover of the scooters like activa aviator dio shine twister unicorn and twister Process like blanking coining and bending of pipes is done

Blanking is cutting up a large sheer of stock into smaller pieces suitable for next operation

Coining is the process of removal of extra material or to make work piece up to the limit All these mechanical presses are of 500 ton and there only one hydraulic press and this press are used to repair the dyes

CNC pipe bending machines are used to bend the pipes which later used in the manufacturing of the frame

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 38

WELDING SECTION In welding section there are six types of welding machines used in manufacturing of frames and body covers

1 Gantry System Gantry system is a system in which gantry crane is used for transporting the frame and welding is done by the robots and welding is finished by the robots the gantry crane picks up the frame and body covers and puts them on the conveyer or the hanger which goes to the weld body storage On gantry system seam welding is done on the body covers and on the frames with the help of the welding robots This system is fully automatic and there is no involvement of human being it picks up the frame and body covers from the location defined to it then does all the processing on it and then passes it to the conveyer

2 MIG Welding Metal inert gas welding in this inert gas argon is used and argon acts as a shielding gas 1-5 oxygen is used This type of welding uses consumable wire electrode during the welding process that is fed from the wire spool MIG welding has some advantages over the other welding techniques It provides a uniform weld it provides a slag free weld beam and needs little clean up

3 Spot Welding Spot welding is a process in which contacting metal surface are joined by the heat obtained from resistance to electric flow and this type of welding is done on the body covers of the scooter

4 Seam Welding It is a process that welds at a surface of overlapped parts along a length of a joint Weld made by overlapping nuggets this type of welding is done on the fuel tanks and mudguards of scooter

5 Portable Spot Welding It is a portable gun which can be taken to specified range where other spot welding machine faces difficulty in welding This type of the welding is done on body covers of scooters

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 39

6 Fine Boring Fine boring is done on the frame where handle has to fit after fine boring handle is attached to it

When various operation of the welding on the different components of the scooter that is frame mudguard body covers and fuel tank is over then this welded body parts are loaded on to a conveyer hanger which takes these body parts to the weld body storage and in the weld body storage and in weld body storage there are three sections one for model 1 one for model 2 and the last for model 3 When welded body is loaded on to a conveyor then the person who loads these bodies on to the hanger select in which model hanger has to go and the selection is done with a selector switch present Up to 300 hangers can be stored in the storage area that means around 600 frames and 600 body covers can be stored in the weld storage area From storage area hangers move to the unloading area and from unloading area these body covers and frames are loaded on to a Carrier which takes them to the paint section Unloading of the frames and body covers depends on the requirement of the assembly line and which model they are making according to their requirement unloading of model frames and body covers is done Unloading of the model is again done by the selector switch that is when there is requirement of model 1 the person who unloads the frame presses model switch and from storage model 1 moves to the unloading area Similarly when there is requirement of model 2 then operator presses model 2 switch and same goes for the model 3 when the requirement is of model 3 the operator presses the model 3 switch and then from storage model 3 moves to unloading bay

3 Top Coat

Loading In this process frames and body covers are mounted on the carrier of the conveyor line There are two lines for the paint that is paint A line and paint B line both the lines are very much important because in A line loading of frames and front body left right cover and rear body covers are loaded and on B line mudguard and front cowl is loaded and after loading of these parts then the carrier moves to the pretreatment zone

Pre-Treatment In pre-treatment degreasing and dust cleaning is done In pre-treatment bodies have to undergo two operations first wasting with the soft water by this process degreasing is done and all the dust particles are removed from the frames and body covers In general first we get hard water is converted to soft water by ion exchange mechanism

Secondly on bodies and frames phosphate cleaning is done by this method any dust particle or any grease particle left on the frames and body cover is removed

Electro-Deposition In electro deposition carrier which carries frame and body covers turn down into the electro deposition chamber and in electro deposition chamber is filled with the base paint or primer When carrier turns down it strikes high voltage wire and it gets negatively charged and become cathode and paint in the chamber becomes anode then a uniform thin film of base paint is deposited on

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 42

the body covers and frames of the scooter This process is repeated twice and after that it is passed to ED oven

ED Oven In electro deposition oven base coat done on the frame and body covers is heated to 150 degree temperature and this base coat is dried here and after that is passed to paint booth

Paint Booth Paint booth has three sections first one is sanding zone second primary coat or under coat and third is top coat

In sanding zone sanding of the frames and body covers is done and after that it is sent to under coat zone in under coat zone single coat of the paint is done on frames and body covers and in this zone coat of paint is done with the help of robots and after that frames and body covers then sent to top coat zone here in this zone second coat of the paint is done and this second coat of paint is done with the operator and after that these frames and body covers are sent to top coat oven

Top Coat Oven In top coat oven these frames and body covers are heated up to 170 degree temperature and dried and then allowed to cool naturally to room temperature and from there it is sent to the inspection zone

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 43

Inspection Zone In inspection zone body covers and frames have to pass infra-red zone Here IR testing machine checks for irregularities in the paint done and after that these body covers and frames are manually checked by hand for any errors in the paint jobs Parts which pass these tests get the OK mark and move to unloading area

Unloading In this area unloading of frames and body covers takes place Frames and body covers having OK mark are loaded to the paint body store and body covers and frames not having OK mark on them are sent to the repair work station and there they fix the problems which frames and body covers have They are then unloaded and then loaded on to the hanger and the parts go to the paint body storage In storage final or finished body covers and frames are stored which from storage area moves to the final assembly line

9 ProjectProject Definition

To study the various parts of the carrier being used in the paint shop and its problem analysis

Project Introduction

Carrier is defined as a thing which supports or holds up a part during its movement It is used to carry parts to the paint shop where various processes can be performed Carrier forms the basis of the Paint Shop because the movement of the parts from one point to another in the paint shop takes place only due to carrier The parts are loaded on the carrier with the help of a jig and then the motion takes place

Paint shop carrier is the most important moving part in the paint process Most problems and the breakdowns in the paint shop occur due to the carrier only It causes loss to the net production Bends or breaks due to load of body part applied on carrier causes distortions which ultimately results in the breakdown

Carrier is a part of the conveyer system being used in the paint shop The other components of the conveyer system are the prime mover drive (works as the input motion source for chain) chain and chain track carrier carrier turn (for turning the carrier) carrier

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 45

revolution (for revolving the carrier) stopper (it temporarily stops the carrier on line) carrier locks auto feeder cylinders and drop lifters which support the motion of carrier

Part Description Of Carrier

Rail

Rail can be of two types ie pre rail and power rail Pre rail is used to drive trolley of the carrier Power rail is used to drive the conveyer system

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 46

Gear Box

Gear Box acts as a Speed Reducer It consists of a worm and worm-wheel arrangement which turns the axis of rotation by 90deg and reduces the speed of the parts The gear box is coupled with the small sprocket Gear transmits power to small sprocket which helps for carrier turn this is also called as reduction gear The relation between the torque and diameter of worm shaft is given by

T (Kg-m) = π16dsup3τ

where τ is the twisting moment

Velocity Ratio = 160

Tensile Strength of Material = 60 Kgmmsup2

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 47

Trolley

There are two trolleys present in a carrier namely Front and the Rear Trolley Front Trolley stops the carrier at a specified position by the actuation of stopper while Rear Trolley stops the next carrier by engaging with the Front trolley of next carrier Trolley Wheel contains ball bearings The outer race serves as a wheel A grease fitting is installed as a greasing port Guide Roller is installed to reduce friction against free rail Pivoting Dog is lifted by the own weight The chain pusher engages to the Pivoting dog for transport To stop the carrier the stopper (installed on the line) pushes down the Pivoting Dog to release the engagement with the pusher

Problem Analysis Of Carrier

Frame Hole NG

During the motion of the carrier when it is suddenly stopped by the stopper vibrations are produced in it and the pin inserted in the hole of the frame enlarges the size of the hole thereby causing the problem of frame hole NG

To reduce this problem an anti back-up system is applied to reduce the vibrations The NG frame hole is repaired by welding a bush at the site of the hole which is a newly developed Kaizen

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 64

Problems Caused By Loading

Improper loading of the frame body on the carrier damages the insulator collar because an unbalanced force acts upon it and insulator collars being the non-metallic parts are severely affected

R is the resultant vector

This is a production problem which causes the bending of jigs unbalancing of the carrier thereby causing improper motion at the carrier turns and revolutions and also resulting in the body parts falling in the oven

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 65

Gear Box Failure

Gear box of the carrier also fails some time due to overloading or improper coupling

Bending of Striker

Overloading at CTs and CRs causes the bending of the strikers which result in altered motion of the carrier

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 66

Breaking of Post

The post of the carrier can be broken due to variable and unbalanced load acting on the carrier The stresses are developed in the post which leads to its breaking Moreover hammering of the nut for the proper locking can also cause the breaking of nut

Overloading

Overloading is the state when the load on a part of the carrier is higher than its tolerance value Its causes are

If any object interrupts the motion of chain chain is not able to move forward properly causing overloading of chain

Improper position of the jig may lead to unbalancing of the carrier and overload may occur

Guide pin may not properly interact with the arm which may lead to non-alignment

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 67

Chain of the carrier turn may not be in proper position leading to overload at CT

Breaking of any of the carrier dogs will lead to improper revolution of the carrier

Other Problems

Cable breaks -gt Current does not reach to body part

ED COLLECTER burns out -gt It would not collect current

Threading of endndashplate striker wear out -gt Striker would not hit limit switch

Bush between coupling is cut

Bearing sometimes disrupts system

Swivel pipe bends -gt Carrier wouldnrsquot be leveled

Insulator sometimes fails to stop current

End plate threading wears

Spindle shaft bends -gt Carrier wouldnrsquot be leveled

Striker and arm also bends

Conclusion

From my project of one month here in HMSI I came to know that how

work goes on in the organization As far as my project of study

maintenance and breakdown analysis of carrier is concerned I came to

know the importance of carrier in paint shop and the production

problems caused by the carrier in the industry The carrier being used in

the paint shop is the best possible system for proper painting of parts

By knowing the various specifications problems related to it can be

solved

8 Introduction to Maintenance Department

Introduction The maintenance department is one of the most important departments of the organization where the organization has its own production Maintenance department of Honda Motorcycle and Scooter India Private Limited (HMSI) is a responsible for all the breakdowns which occur in the machines or where there is any production loss so when to overcome the problem of production loss maintenance team has to work efficiently so that there is no mistake committed by them by which production loss occurs

Some important definitions used by maintenance

Maintenance Action necessary for retaining or restoring an equipment machine or system to the specified operable condition to achieve its maximum useful life It includes planned and preventive maintenance

Planned Maintenance Preventive maintenance carried out according to a fixed plan is called planned maintenance

Preventive Maintenance Systematic inspection detection correction and prevention of incipient failures before they become actual or major failures is called as preventive maintenance

Breakdown Maintenance Repair or replacements performed after a machine has failed to return to its functional state following a malfunction or shutdown is called as breakdown maintenance

Predictive Maintenance Type of preventive maintenance performed continuously or at interval according to the requirement to diagnose and

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 36

monitor a condition or system also called condition based maintenance is called as predictive maintenance

Mean Time To Repair (MTTR) Basic measure of maintainability of repairable items it represents the average mean time required to repair a failed component or device is defined as mean time to repair

Mean Time Between Failures (MTBF) Basic measure of the reliability of repairable items it represents the average number of a life units during which all parts of a device or system perform within their specified limits under specified conditions are called as mean time between failures

Down Time Period during which an equipment or machine is not functional or cannot work It may be due to technical failures mechanical adjustments maintenance or non availability of inputs such as materials labor and power etc is called as down time

Frame Maintenance In this department there are three sections

1 Press Section

2 Weld Section

Engine Maintenance Frame Maintenance

3 Paint Section

PRESS SECTION Press section has mainly four machines

Komatsu Pressndash3

AIDA Press -1

CNC bending machine

Hind Press

These presses are mechanical presses and on this press mudguard fuel tank nose and body cover of the scooters like activa aviator dio shine twister unicorn and twister Process like blanking coining and bending of pipes is done

Blanking is cutting up a large sheer of stock into smaller pieces suitable for next operation

Coining is the process of removal of extra material or to make work piece up to the limit All these mechanical presses are of 500 ton and there only one hydraulic press and this press are used to repair the dyes

CNC pipe bending machines are used to bend the pipes which later used in the manufacturing of the frame

WELDING SECTION In welding section there are six types of welding machines used in manufacturing of frames and body covers

1 Gantry System Gantry system is a system in which gantry crane is used for transporting the frame and welding is done by the robots and welding is finished by the robots the gantry crane picks up the frame and body covers and puts them on the conveyer or the hanger which goes to the weld body storage On gantry system seam welding is done on the body covers and on the frames with the help of the welding robots This system is fully automatic and there is no involvement of human being it picks up the frame and body covers from the location defined to it then does all the processing on it and then passes it to the conveyer

2 MIG Welding Metal inert gas welding in this inert gas argon is used and argon acts as a shielding gas 1-5 oxygen is used This type of welding uses consumable wire electrode during the welding process that is fed from the wire spool MIG welding has some advantages over the other welding techniques It provides a uniform weld it provides a slag free weld beam and needs little clean up

3 Spot Welding Spot welding is a process in which contacting metal surface are joined by the heat obtained from resistance to electric flow and this type of welding is done on the body covers of the scooter

4 Seam Welding It is a process that welds at a surface of overlapped parts along a length of a joint Weld made by overlapping nuggets this type of welding is done on the fuel tanks and mudguards of scooter

5 Portable Spot Welding It is a portable gun which can be taken to specified range where other spot welding machine faces difficulty in welding This type of the welding is done on body covers of scooters

6 Fine Boring Fine boring is done on the frame where handle has to fit after fine boring handle is attached to it

When various operation of the welding on the different components of the scooter that is frame mudguard body covers and fuel tank is over then this welded body parts are loaded on to a conveyer hanger which takes these body parts to the weld body storage and in the weld body storage and in weld body storage there are three sections one for model 1 one for model 2 and the last for model 3 When welded body is loaded on to a conveyor then the person who loads these bodies on to the hanger select in which model hanger has to go and the selection is done with a selector switch present Up to 300 hangers can be stored in the storage area that means around 600 frames and 600 body covers can be stored in the weld storage area From storage area hangers move to the unloading area and from unloading area these body covers and frames are loaded on to a Carrier which takes them to the paint section Unloading of the frames and body covers depends on the requirement of the assembly line and which model they are making according to their requirement unloading of model frames and body covers is done Unloading of the model is again done by the selector switch that is when there is requirement of model 1 the person who unloads the frame presses model switch and from storage model 1 moves to the unloading area Similarly when there is requirement of model 2 then operator presses model 2 switch and same goes for the model 3 when the requirement is of model 3 the operator presses the model 3 switch and then from storage model 3 moves to unloading bay

PAINT SECTION Paint section is very important section In this section different treatments are done on the body covers and frames and it is a step by step process done as follows

Loading

Pre-Treatment

Electro-Deposition

ED Oven

Booth

Top Coat Oven

Inspection Zone

Unloading

PAINT PROCESS FLOW

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 41

1 Sanding Zone

2 Under Coat

3 Top Coat

Loading In this process frames and body covers are mounted on the carrier of the conveyor line There are two lines for the paint that is paint A line and paint B line both the lines are very much important because in A line loading of frames and front body left right cover and rear body covers are loaded and on B line mudguard and front cowl is loaded and after loading of these parts then the carrier moves to the pretreatment zone

Pre-Treatment In pre-treatment degreasing and dust cleaning is done In pre-treatment bodies have to undergo two operations first wasting with the soft water by this process degreasing is done and all the dust particles are removed from the frames and body covers In general first we get hard water is converted to soft water by ion exchange mechanism

Secondly on bodies and frames phosphate cleaning is done by this method any dust particle or any grease particle left on the frames and body cover is removed

Electro-Deposition In electro deposition carrier which carries frame and body covers turn down into the electro deposition chamber and in electro deposition chamber is filled with the base paint or primer When carrier turns down it strikes high voltage wire and it gets negatively charged and become cathode and paint in the chamber becomes anode then a uniform thin film of base paint is deposited on

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 42

the body covers and frames of the scooter This process is repeated twice and after that it is passed to ED oven

ED Oven In electro deposition oven base coat done on the frame and body covers is heated to 150 degree temperature and this base coat is dried here and after that is passed to paint booth

Paint Booth Paint booth has three sections first one is sanding zone second primary coat or under coat and third is top coat

In sanding zone sanding of the frames and body covers is done and after that it is sent to under coat zone in under coat zone single coat of the paint is done on frames and body covers and in this zone coat of paint is done with the help of robots and after that frames and body covers then sent to top coat zone here in this zone second coat of the paint is done and this second coat of paint is done with the operator and after that these frames and body covers are sent to top coat oven

Top Coat Oven In top coat oven these frames and body covers are heated up to 170 degree temperature and dried and then allowed to cool naturally to room temperature and from there it is sent to the inspection zone

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 43

Inspection Zone In inspection zone body covers and frames have to pass infra-red zone Here IR testing machine checks for irregularities in the paint done and after that these body covers and frames are manually checked by hand for any errors in the paint jobs Parts which pass these tests get the OK mark and move to unloading area

Unloading In this area unloading of frames and body covers takes place Frames and body covers having OK mark are loaded to the paint body store and body covers and frames not having OK mark on them are sent to the repair work station and there they fix the problems which frames and body covers have They are then unloaded and then loaded on to the hanger and the parts go to the paint body storage In storage final or finished body covers and frames are stored which from storage area moves to the final assembly line

9 ProjectProject Definition

To study the various parts of the carrier being used in the paint shop and its problem analysis

Project Introduction

Carrier is defined as a thing which supports or holds up a part during its movement It is used to carry parts to the paint shop where various processes can be performed Carrier forms the basis of the Paint Shop because the movement of the parts from one point to another in the paint shop takes place only due to carrier The parts are loaded on the carrier with the help of a jig and then the motion takes place

Paint shop carrier is the most important moving part in the paint process Most problems and the breakdowns in the paint shop occur due to the carrier only It causes loss to the net production Bends or breaks due to load of body part applied on carrier causes distortions which ultimately results in the breakdown

Carrier is a part of the conveyer system being used in the paint shop The other components of the conveyer system are the prime mover drive (works as the input motion source for chain) chain and chain track carrier carrier turn (for turning the carrier) carrier

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 45

revolution (for revolving the carrier) stopper (it temporarily stops the carrier on line) carrier locks auto feeder cylinders and drop lifters which support the motion of carrier

Part Description Of Carrier

Rail

Rail can be of two types ie pre rail and power rail Pre rail is used to drive trolley of the carrier Power rail is used to drive the conveyer system

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 46

Gear Box

Gear Box acts as a Speed Reducer It consists of a worm and worm-wheel arrangement which turns the axis of rotation by 90deg and reduces the speed of the parts The gear box is coupled with the small sprocket Gear transmits power to small sprocket which helps for carrier turn this is also called as reduction gear The relation between the torque and diameter of worm shaft is given by

T (Kg-m) = π16dsup3τ

where τ is the twisting moment

Velocity Ratio = 160

Tensile Strength of Material = 60 Kgmmsup2

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 47

Trolley

There are two trolleys present in a carrier namely Front and the Rear Trolley Front Trolley stops the carrier at a specified position by the actuation of stopper while Rear Trolley stops the next carrier by engaging with the Front trolley of next carrier Trolley Wheel contains ball bearings The outer race serves as a wheel A grease fitting is installed as a greasing port Guide Roller is installed to reduce friction against free rail Pivoting Dog is lifted by the own weight The chain pusher engages to the Pivoting dog for transport To stop the carrier the stopper (installed on the line) pushes down the Pivoting Dog to release the engagement with the pusher

Swivel Pipe

Swivel pipe is used to drive carrier during carrier revolution Swivel pipe is connected to the shaft of worm gear thus it also gets its power from the gear box

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 48

Problem Analysis Of Carrier

Frame Hole NG

During the motion of the carrier when it is suddenly stopped by the stopper vibrations are produced in it and the pin inserted in the hole of the frame enlarges the size of the hole thereby causing the problem of frame hole NG

To reduce this problem an anti back-up system is applied to reduce the vibrations The NG frame hole is repaired by welding a bush at the site of the hole which is a newly developed Kaizen

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 64

Problems Caused By Loading

Improper loading of the frame body on the carrier damages the insulator collar because an unbalanced force acts upon it and insulator collars being the non-metallic parts are severely affected

R is the resultant vector

This is a production problem which causes the bending of jigs unbalancing of the carrier thereby causing improper motion at the carrier turns and revolutions and also resulting in the body parts falling in the oven

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 65

Gear Box Failure

Gear box of the carrier also fails some time due to overloading or improper coupling

Bending of Striker

Overloading at CTs and CRs causes the bending of the strikers which result in altered motion of the carrier

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 66

Breaking of Post

The post of the carrier can be broken due to variable and unbalanced load acting on the carrier The stresses are developed in the post which leads to its breaking Moreover hammering of the nut for the proper locking can also cause the breaking of nut

Overloading

Overloading is the state when the load on a part of the carrier is higher than its tolerance value Its causes are

If any object interrupts the motion of chain chain is not able to move forward properly causing overloading of chain

Improper position of the jig may lead to unbalancing of the carrier and overload may occur

Guide pin may not properly interact with the arm which may lead to non-alignment

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 67

Chain of the carrier turn may not be in proper position leading to overload at CT

Breaking of any of the carrier dogs will lead to improper revolution of the carrier

Other Problems

Cable breaks -gt Current does not reach to body part

ED COLLECTER burns out -gt It would not collect current

Threading of endndashplate striker wear out -gt Striker would not hit limit switch

Bush between coupling is cut

Bearing sometimes disrupts system

Swivel pipe bends -gt Carrier wouldnrsquot be leveled

Insulator sometimes fails to stop current

End plate threading wears

Spindle shaft bends -gt Carrier wouldnrsquot be leveled

Striker and arm also bends

Conclusion

From my project of one month here in HMSI I came to know that how

work goes on in the organization As far as my project of study

maintenance and breakdown analysis of carrier is concerned I came to

know the importance of carrier in paint shop and the production

problems caused by the carrier in the industry The carrier being used in

the paint shop is the best possible system for proper painting of parts

By knowing the various specifications problems related to it can be

solved

8 Introduction to Maintenance Department

Introduction The maintenance department is one of the most important departments of the organization where the organization has its own production Maintenance department of Honda Motorcycle and Scooter India Private Limited (HMSI) is a responsible for all the breakdowns which occur in the machines or where there is any production loss so when to overcome the problem of production loss maintenance team has to work efficiently so that there is no mistake committed by them by which production loss occurs

Some important definitions used by maintenance

Maintenance Action necessary for retaining or restoring an equipment machine or system to the specified operable condition to achieve its maximum useful life It includes planned and preventive maintenance

Planned Maintenance Preventive maintenance carried out according to a fixed plan is called planned maintenance

Preventive Maintenance Systematic inspection detection correction and prevention of incipient failures before they become actual or major failures is called as preventive maintenance

Breakdown Maintenance Repair or replacements performed after a machine has failed to return to its functional state following a malfunction or shutdown is called as breakdown maintenance

Predictive Maintenance Type of preventive maintenance performed continuously or at interval according to the requirement to diagnose and

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 36

monitor a condition or system also called condition based maintenance is called as predictive maintenance

Mean Time To Repair (MTTR) Basic measure of maintainability of repairable items it represents the average mean time required to repair a failed component or device is defined as mean time to repair

Mean Time Between Failures (MTBF) Basic measure of the reliability of repairable items it represents the average number of a life units during which all parts of a device or system perform within their specified limits under specified conditions are called as mean time between failures

Down Time Period during which an equipment or machine is not functional or cannot work It may be due to technical failures mechanical adjustments maintenance or non availability of inputs such as materials labor and power etc is called as down time

Frame Maintenance In this department there are three sections

1 Press Section

2 Weld Section

3 Paint Section

PRESS SECTION Press section has mainly four machines

Komatsu Pressndash3

AIDA Press -1

CNC bending machine

Hind Press

These presses are mechanical presses and on this press mudguard fuel tank nose and body cover of the scooters like activa aviator dio shine twister unicorn and twister Process like blanking coining and bending of pipes is done

Blanking is cutting up a large sheer of stock into smaller pieces suitable for next operation

Coining is the process of removal of extra material or to make work piece up to the limit All these mechanical presses are of 500 ton and there only one hydraulic press and this press are used to repair the dyes

CNC pipe bending machines are used to bend the pipes which later used in the manufacturing of the frame

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 38

WELDING SECTION In welding section there are six types of welding machines used in manufacturing of frames and body covers

1 Gantry System Gantry system is a system in which gantry crane is used for transporting the frame and welding is done by the robots and welding is finished by the robots the gantry crane picks up the frame and body covers and puts them on the conveyer or the hanger which goes to the weld body storage On gantry system seam welding is done on the body covers and on the frames with the help of the welding robots This system is fully automatic and there is no involvement of human being it picks up the frame and body covers from the location defined to it then does all the processing on it and then passes it to the conveyer

2 MIG Welding Metal inert gas welding in this inert gas argon is used and argon acts as a shielding gas 1-5 oxygen is used This type of welding uses consumable wire electrode during the welding process that is fed from the wire spool MIG welding has some advantages over the other welding techniques It provides a uniform weld it provides a slag free weld beam and needs little clean up

3 Spot Welding Spot welding is a process in which contacting metal surface are joined by the heat obtained from resistance to electric flow and this type of welding is done on the body covers of the scooter

4 Seam Welding It is a process that welds at a surface of overlapped parts along a length of a joint Weld made by overlapping nuggets this type of welding is done on the fuel tanks and mudguards of scooter

5 Portable Spot Welding It is a portable gun which can be taken to specified range where other spot welding machine faces difficulty in welding This type of the welding is done on body covers of scooters

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 39

6 Fine Boring Fine boring is done on the frame where handle has to fit after fine boring handle is attached to it

When various operation of the welding on the different components of the scooter that is frame mudguard body covers and fuel tank is over then this welded body parts are loaded on to a conveyer hanger which takes these body parts to the weld body storage and in the weld body storage and in weld body storage there are three sections one for model 1 one for model 2 and the last for model 3 When welded body is loaded on to a conveyor then the person who loads these bodies on to the hanger select in which model hanger has to go and the selection is done with a selector switch present Up to 300 hangers can be stored in the storage area that means around 600 frames and 600 body covers can be stored in the weld storage area From storage area hangers move to the unloading area and from unloading area these body covers and frames are loaded on to a Carrier which takes them to the paint section Unloading of the frames and body covers depends on the requirement of the assembly line and which model they are making according to their requirement unloading of model frames and body covers is done Unloading of the model is again done by the selector switch that is when there is requirement of model 1 the person who unloads the frame presses model switch and from storage model 1 moves to the unloading area Similarly when there is requirement of model 2 then operator presses model 2 switch and same goes for the model 3 when the requirement is of model 3 the operator presses the model 3 switch and then from storage model 3 moves to unloading bay

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 41

1 Sanding Zone

2 Under Coat

3 Top Coat

Loading In this process frames and body covers are mounted on the carrier of the conveyor line There are two lines for the paint that is paint A line and paint B line both the lines are very much important because in A line loading of frames and front body left right cover and rear body covers are loaded and on B line mudguard and front cowl is loaded and after loading of these parts then the carrier moves to the pretreatment zone

Pre-Treatment In pre-treatment degreasing and dust cleaning is done In pre-treatment bodies have to undergo two operations first wasting with the soft water by this process degreasing is done and all the dust particles are removed from the frames and body covers In general first we get hard water is converted to soft water by ion exchange mechanism

Secondly on bodies and frames phosphate cleaning is done by this method any dust particle or any grease particle left on the frames and body cover is removed

Electro-Deposition In electro deposition carrier which carries frame and body covers turn down into the electro deposition chamber and in electro deposition chamber is filled with the base paint or primer When carrier turns down it strikes high voltage wire and it gets negatively charged and become cathode and paint in the chamber becomes anode then a uniform thin film of base paint is deposited on

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 42

the body covers and frames of the scooter This process is repeated twice and after that it is passed to ED oven

ED Oven In electro deposition oven base coat done on the frame and body covers is heated to 150 degree temperature and this base coat is dried here and after that is passed to paint booth

Paint Booth Paint booth has three sections first one is sanding zone second primary coat or under coat and third is top coat

In sanding zone sanding of the frames and body covers is done and after that it is sent to under coat zone in under coat zone single coat of the paint is done on frames and body covers and in this zone coat of paint is done with the help of robots and after that frames and body covers then sent to top coat zone here in this zone second coat of the paint is done and this second coat of paint is done with the operator and after that these frames and body covers are sent to top coat oven

Top Coat Oven In top coat oven these frames and body covers are heated up to 170 degree temperature and dried and then allowed to cool naturally to room temperature and from there it is sent to the inspection zone

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 43

Inspection Zone In inspection zone body covers and frames have to pass infra-red zone Here IR testing machine checks for irregularities in the paint done and after that these body covers and frames are manually checked by hand for any errors in the paint jobs Parts which pass these tests get the OK mark and move to unloading area

Unloading In this area unloading of frames and body covers takes place Frames and body covers having OK mark are loaded to the paint body store and body covers and frames not having OK mark on them are sent to the repair work station and there they fix the problems which frames and body covers have They are then unloaded and then loaded on to the hanger and the parts go to the paint body storage In storage final or finished body covers and frames are stored which from storage area moves to the final assembly line

9 ProjectProject Definition

To study the various parts of the carrier being used in the paint shop and its problem analysis

Project Introduction

Carrier is defined as a thing which supports or holds up a part during its movement It is used to carry parts to the paint shop where various processes can be performed Carrier forms the basis of the Paint Shop because the movement of the parts from one point to another in the paint shop takes place only due to carrier The parts are loaded on the carrier with the help of a jig and then the motion takes place

Paint shop carrier is the most important moving part in the paint process Most problems and the breakdowns in the paint shop occur due to the carrier only It causes loss to the net production Bends or breaks due to load of body part applied on carrier causes distortions which ultimately results in the breakdown

Carrier is a part of the conveyer system being used in the paint shop The other components of the conveyer system are the prime mover drive (works as the input motion source for chain) chain and chain track carrier carrier turn (for turning the carrier) carrier

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 45

revolution (for revolving the carrier) stopper (it temporarily stops the carrier on line) carrier locks auto feeder cylinders and drop lifters which support the motion of carrier

Part Description Of Carrier

Rail

Problem Analysis Of Carrier

Frame Hole NG

During the motion of the carrier when it is suddenly stopped by the stopper vibrations are produced in it and the pin inserted in the hole of the frame enlarges the size of the hole thereby causing the problem of frame hole NG

To reduce this problem an anti back-up system is applied to reduce the vibrations The NG frame hole is repaired by welding a bush at the site of the hole which is a newly developed Kaizen

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 64

Problems Caused By Loading

Improper loading of the frame body on the carrier damages the insulator collar because an unbalanced force acts upon it and insulator collars being the non-metallic parts are severely affected

R is the resultant vector

This is a production problem which causes the bending of jigs unbalancing of the carrier thereby causing improper motion at the carrier turns and revolutions and also resulting in the body parts falling in the oven

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 65

Gear Box Failure

Gear box of the carrier also fails some time due to overloading or improper coupling

Bending of Striker

Overloading at CTs and CRs causes the bending of the strikers which result in altered motion of the carrier

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 66

Breaking of Post

The post of the carrier can be broken due to variable and unbalanced load acting on the carrier The stresses are developed in the post which leads to its breaking Moreover hammering of the nut for the proper locking can also cause the breaking of nut

Overloading

Overloading is the state when the load on a part of the carrier is higher than its tolerance value Its causes are

If any object interrupts the motion of chain chain is not able to move forward properly causing overloading of chain

Improper position of the jig may lead to unbalancing of the carrier and overload may occur

Guide pin may not properly interact with the arm which may lead to non-alignment

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 67

Chain of the carrier turn may not be in proper position leading to overload at CT

Breaking of any of the carrier dogs will lead to improper revolution of the carrier

Other Problems

Cable breaks -gt Current does not reach to body part

ED COLLECTER burns out -gt It would not collect current

Threading of endndashplate striker wear out -gt Striker would not hit limit switch

Bush between coupling is cut

Bearing sometimes disrupts system

Swivel pipe bends -gt Carrier wouldnrsquot be leveled

Insulator sometimes fails to stop current

End plate threading wears

Spindle shaft bends -gt Carrier wouldnrsquot be leveled

Striker and arm also bends

8 Introduction to Maintenance Department

Introduction The maintenance department is one of the most important departments of the organization where the organization has its own production Maintenance department of Honda Motorcycle and Scooter India Private Limited (HMSI) is a responsible for all the breakdowns which occur in the machines or where there is any production loss so when to overcome the problem of production loss maintenance team has to work efficiently so that there is no mistake committed by them by which production loss occurs

Some important definitions used by maintenance

Maintenance Action necessary for retaining or restoring an equipment machine or system to the specified operable condition to achieve its maximum useful life It includes planned and preventive maintenance

Planned Maintenance Preventive maintenance carried out according to a fixed plan is called planned maintenance

Preventive Maintenance Systematic inspection detection correction and prevention of incipient failures before they become actual or major failures is called as preventive maintenance

Breakdown Maintenance Repair or replacements performed after a machine has failed to return to its functional state following a malfunction or shutdown is called as breakdown maintenance

Predictive Maintenance Type of preventive maintenance performed continuously or at interval according to the requirement to diagnose and

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 36

monitor a condition or system also called condition based maintenance is called as predictive maintenance

Mean Time To Repair (MTTR) Basic measure of maintainability of repairable items it represents the average mean time required to repair a failed component or device is defined as mean time to repair

Mean Time Between Failures (MTBF) Basic measure of the reliability of repairable items it represents the average number of a life units during which all parts of a device or system perform within their specified limits under specified conditions are called as mean time between failures

Down Time Period during which an equipment or machine is not functional or cannot work It may be due to technical failures mechanical adjustments maintenance or non availability of inputs such as materials labor and power etc is called as down time

Frame Maintenance In this department there are three sections

1 Press Section

2 Weld Section

3 Paint Section

PRESS SECTION Press section has mainly four machines

Komatsu Pressndash3

AIDA Press -1

CNC bending machine

Hind Press

These presses are mechanical presses and on this press mudguard fuel tank nose and body cover of the scooters like activa aviator dio shine twister unicorn and twister Process like blanking coining and bending of pipes is done

Blanking is cutting up a large sheer of stock into smaller pieces suitable for next operation

Coining is the process of removal of extra material or to make work piece up to the limit All these mechanical presses are of 500 ton and there only one hydraulic press and this press are used to repair the dyes

CNC pipe bending machines are used to bend the pipes which later used in the manufacturing of the frame

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 38

WELDING SECTION In welding section there are six types of welding machines used in manufacturing of frames and body covers

1 Gantry System Gantry system is a system in which gantry crane is used for transporting the frame and welding is done by the robots and welding is finished by the robots the gantry crane picks up the frame and body covers and puts them on the conveyer or the hanger which goes to the weld body storage On gantry system seam welding is done on the body covers and on the frames with the help of the welding robots This system is fully automatic and there is no involvement of human being it picks up the frame and body covers from the location defined to it then does all the processing on it and then passes it to the conveyer

2 MIG Welding Metal inert gas welding in this inert gas argon is used and argon acts as a shielding gas 1-5 oxygen is used This type of welding uses consumable wire electrode during the welding process that is fed from the wire spool MIG welding has some advantages over the other welding techniques It provides a uniform weld it provides a slag free weld beam and needs little clean up

3 Spot Welding Spot welding is a process in which contacting metal surface are joined by the heat obtained from resistance to electric flow and this type of welding is done on the body covers of the scooter

4 Seam Welding It is a process that welds at a surface of overlapped parts along a length of a joint Weld made by overlapping nuggets this type of welding is done on the fuel tanks and mudguards of scooter

5 Portable Spot Welding It is a portable gun which can be taken to specified range where other spot welding machine faces difficulty in welding This type of the welding is done on body covers of scooters

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 39

6 Fine Boring Fine boring is done on the frame where handle has to fit after fine boring handle is attached to it

When various operation of the welding on the different components of the scooter that is frame mudguard body covers and fuel tank is over then this welded body parts are loaded on to a conveyer hanger which takes these body parts to the weld body storage and in the weld body storage and in weld body storage there are three sections one for model 1 one for model 2 and the last for model 3 When welded body is loaded on to a conveyor then the person who loads these bodies on to the hanger select in which model hanger has to go and the selection is done with a selector switch present Up to 300 hangers can be stored in the storage area that means around 600 frames and 600 body covers can be stored in the weld storage area From storage area hangers move to the unloading area and from unloading area these body covers and frames are loaded on to a Carrier which takes them to the paint section Unloading of the frames and body covers depends on the requirement of the assembly line and which model they are making according to their requirement unloading of model frames and body covers is done Unloading of the model is again done by the selector switch that is when there is requirement of model 1 the person who unloads the frame presses model switch and from storage model 1 moves to the unloading area Similarly when there is requirement of model 2 then operator presses model 2 switch and same goes for the model 3 when the requirement is of model 3 the operator presses the model 3 switch and then from storage model 3 moves to unloading bay

3 Top Coat

Loading In this process frames and body covers are mounted on the carrier of the conveyor line There are two lines for the paint that is paint A line and paint B line both the lines are very much important because in A line loading of frames and front body left right cover and rear body covers are loaded and on B line mudguard and front cowl is loaded and after loading of these parts then the carrier moves to the pretreatment zone

Pre-Treatment In pre-treatment degreasing and dust cleaning is done In pre-treatment bodies have to undergo two operations first wasting with the soft water by this process degreasing is done and all the dust particles are removed from the frames and body covers In general first we get hard water is converted to soft water by ion exchange mechanism

Secondly on bodies and frames phosphate cleaning is done by this method any dust particle or any grease particle left on the frames and body cover is removed

Electro-Deposition In electro deposition carrier which carries frame and body covers turn down into the electro deposition chamber and in electro deposition chamber is filled with the base paint or primer When carrier turns down it strikes high voltage wire and it gets negatively charged and become cathode and paint in the chamber becomes anode then a uniform thin film of base paint is deposited on

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 42

the body covers and frames of the scooter This process is repeated twice and after that it is passed to ED oven

ED Oven In electro deposition oven base coat done on the frame and body covers is heated to 150 degree temperature and this base coat is dried here and after that is passed to paint booth

Paint Booth Paint booth has three sections first one is sanding zone second primary coat or under coat and third is top coat

In sanding zone sanding of the frames and body covers is done and after that it is sent to under coat zone in under coat zone single coat of the paint is done on frames and body covers and in this zone coat of paint is done with the help of robots and after that frames and body covers then sent to top coat zone here in this zone second coat of the paint is done and this second coat of paint is done with the operator and after that these frames and body covers are sent to top coat oven

Top Coat Oven In top coat oven these frames and body covers are heated up to 170 degree temperature and dried and then allowed to cool naturally to room temperature and from there it is sent to the inspection zone

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 43

Inspection Zone In inspection zone body covers and frames have to pass infra-red zone Here IR testing machine checks for irregularities in the paint done and after that these body covers and frames are manually checked by hand for any errors in the paint jobs Parts which pass these tests get the OK mark and move to unloading area

Unloading In this area unloading of frames and body covers takes place Frames and body covers having OK mark are loaded to the paint body store and body covers and frames not having OK mark on them are sent to the repair work station and there they fix the problems which frames and body covers have They are then unloaded and then loaded on to the hanger and the parts go to the paint body storage In storage final or finished body covers and frames are stored which from storage area moves to the final assembly line

9 ProjectProject Definition

To study the various parts of the carrier being used in the paint shop and its problem analysis

Project Introduction

Carrier is defined as a thing which supports or holds up a part during its movement It is used to carry parts to the paint shop where various processes can be performed Carrier forms the basis of the Paint Shop because the movement of the parts from one point to another in the paint shop takes place only due to carrier The parts are loaded on the carrier with the help of a jig and then the motion takes place

Paint shop carrier is the most important moving part in the paint process Most problems and the breakdowns in the paint shop occur due to the carrier only It causes loss to the net production Bends or breaks due to load of body part applied on carrier causes distortions which ultimately results in the breakdown

Carrier is a part of the conveyer system being used in the paint shop The other components of the conveyer system are the prime mover drive (works as the input motion source for chain) chain and chain track carrier carrier turn (for turning the carrier) carrier

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 45

revolution (for revolving the carrier) stopper (it temporarily stops the carrier on line) carrier locks auto feeder cylinders and drop lifters which support the motion of carrier

Part Description Of Carrier

Rail

Rail can be of two types ie pre rail and power rail Pre rail is used to drive trolley of the carrier Power rail is used to drive the conveyer system

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 46

Gear Box

Gear Box acts as a Speed Reducer It consists of a worm and worm-wheel arrangement which turns the axis of rotation by 90deg and reduces the speed of the parts The gear box is coupled with the small sprocket Gear transmits power to small sprocket which helps for carrier turn this is also called as reduction gear The relation between the torque and diameter of worm shaft is given by

T (Kg-m) = π16dsup3τ

where τ is the twisting moment

Velocity Ratio = 160

Tensile Strength of Material = 60 Kgmmsup2

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 47

Trolley

There are two trolleys present in a carrier namely Front and the Rear Trolley Front Trolley stops the carrier at a specified position by the actuation of stopper while Rear Trolley stops the next carrier by engaging with the Front trolley of next carrier Trolley Wheel contains ball bearings The outer race serves as a wheel A grease fitting is installed as a greasing port Guide Roller is installed to reduce friction against free rail Pivoting Dog is lifted by the own weight The chain pusher engages to the Pivoting dog for transport To stop the carrier the stopper (installed on the line) pushes down the Pivoting Dog to release the engagement with the pusher

Swivel Pipe

Swivel pipe is used to drive carrier during carrier revolution Swivel pipe is connected to the shaft of worm gear thus it also gets its power from the gear box

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 48

Big Sprocket

Problem Analysis Of Carrier

Frame Hole NG

During the motion of the carrier when it is suddenly stopped by the stopper vibrations are produced in it and the pin inserted in the hole of the frame enlarges the size of the hole thereby causing the problem of frame hole NG

To reduce this problem an anti back-up system is applied to reduce the vibrations The NG frame hole is repaired by welding a bush at the site of the hole which is a newly developed Kaizen

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 64

Problems Caused By Loading

Improper loading of the frame body on the carrier damages the insulator collar because an unbalanced force acts upon it and insulator collars being the non-metallic parts are severely affected

R is the resultant vector

This is a production problem which causes the bending of jigs unbalancing of the carrier thereby causing improper motion at the carrier turns and revolutions and also resulting in the body parts falling in the oven

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 65

Gear Box Failure

Gear box of the carrier also fails some time due to overloading or improper coupling

Bending of Striker

Overloading at CTs and CRs causes the bending of the strikers which result in altered motion of the carrier

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 66

Breaking of Post

The post of the carrier can be broken due to variable and unbalanced load acting on the carrier The stresses are developed in the post which leads to its breaking Moreover hammering of the nut for the proper locking can also cause the breaking of nut

Overloading

Overloading is the state when the load on a part of the carrier is higher than its tolerance value Its causes are

If any object interrupts the motion of chain chain is not able to move forward properly causing overloading of chain

Improper position of the jig may lead to unbalancing of the carrier and overload may occur

Guide pin may not properly interact with the arm which may lead to non-alignment

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 67

Chain of the carrier turn may not be in proper position leading to overload at CT

Breaking of any of the carrier dogs will lead to improper revolution of the carrier

Other Problems

Cable breaks -gt Current does not reach to body part

ED COLLECTER burns out -gt It would not collect current

Threading of endndashplate striker wear out -gt Striker would not hit limit switch

Bush between coupling is cut

Bearing sometimes disrupts system

Swivel pipe bends -gt Carrier wouldnrsquot be leveled

Insulator sometimes fails to stop current

End plate threading wears

Spindle shaft bends -gt Carrier wouldnrsquot be leveled

Striker and arm also bends

8 Introduction to Maintenance Department

Introduction The maintenance department is one of the most important departments of the organization where the organization has its own production Maintenance department of Honda Motorcycle and Scooter India Private Limited (HMSI) is a responsible for all the breakdowns which occur in the machines or where there is any production loss so when to overcome the problem of production loss maintenance team has to work efficiently so that there is no mistake committed by them by which production loss occurs

Some important definitions used by maintenance

Maintenance Action necessary for retaining or restoring an equipment machine or system to the specified operable condition to achieve its maximum useful life It includes planned and preventive maintenance

Planned Maintenance Preventive maintenance carried out according to a fixed plan is called planned maintenance

Preventive Maintenance Systematic inspection detection correction and prevention of incipient failures before they become actual or major failures is called as preventive maintenance

Breakdown Maintenance Repair or replacements performed after a machine has failed to return to its functional state following a malfunction or shutdown is called as breakdown maintenance

Predictive Maintenance Type of preventive maintenance performed continuously or at interval according to the requirement to diagnose and

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 36

monitor a condition or system also called condition based maintenance is called as predictive maintenance

Mean Time To Repair (MTTR) Basic measure of maintainability of repairable items it represents the average mean time required to repair a failed component or device is defined as mean time to repair

Mean Time Between Failures (MTBF) Basic measure of the reliability of repairable items it represents the average number of a life units during which all parts of a device or system perform within their specified limits under specified conditions are called as mean time between failures

Down Time Period during which an equipment or machine is not functional or cannot work It may be due to technical failures mechanical adjustments maintenance or non availability of inputs such as materials labor and power etc is called as down time

Frame Maintenance In this department there are three sections

1 Press Section

2 Weld Section

Engine Maintenance Frame Maintenance

3 Paint Section

PRESS SECTION Press section has mainly four machines

Komatsu Pressndash3

AIDA Press -1

CNC bending machine

Hind Press

These presses are mechanical presses and on this press mudguard fuel tank nose and body cover of the scooters like activa aviator dio shine twister unicorn and twister Process like blanking coining and bending of pipes is done

Blanking is cutting up a large sheer of stock into smaller pieces suitable for next operation

Coining is the process of removal of extra material or to make work piece up to the limit All these mechanical presses are of 500 ton and there only one hydraulic press and this press are used to repair the dyes

CNC pipe bending machines are used to bend the pipes which later used in the manufacturing of the frame

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 38

WELDING SECTION In welding section there are six types of welding machines used in manufacturing of frames and body covers

1 Gantry System Gantry system is a system in which gantry crane is used for transporting the frame and welding is done by the robots and welding is finished by the robots the gantry crane picks up the frame and body covers and puts them on the conveyer or the hanger which goes to the weld body storage On gantry system seam welding is done on the body covers and on the frames with the help of the welding robots This system is fully automatic and there is no involvement of human being it picks up the frame and body covers from the location defined to it then does all the processing on it and then passes it to the conveyer

2 MIG Welding Metal inert gas welding in this inert gas argon is used and argon acts as a shielding gas 1-5 oxygen is used This type of welding uses consumable wire electrode during the welding process that is fed from the wire spool MIG welding has some advantages over the other welding techniques It provides a uniform weld it provides a slag free weld beam and needs little clean up

3 Spot Welding Spot welding is a process in which contacting metal surface are joined by the heat obtained from resistance to electric flow and this type of welding is done on the body covers of the scooter

4 Seam Welding It is a process that welds at a surface of overlapped parts along a length of a joint Weld made by overlapping nuggets this type of welding is done on the fuel tanks and mudguards of scooter

5 Portable Spot Welding It is a portable gun which can be taken to specified range where other spot welding machine faces difficulty in welding This type of the welding is done on body covers of scooters

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 39

6 Fine Boring Fine boring is done on the frame where handle has to fit after fine boring handle is attached to it

When various operation of the welding on the different components of the scooter that is frame mudguard body covers and fuel tank is over then this welded body parts are loaded on to a conveyer hanger which takes these body parts to the weld body storage and in the weld body storage and in weld body storage there are three sections one for model 1 one for model 2 and the last for model 3 When welded body is loaded on to a conveyor then the person who loads these bodies on to the hanger select in which model hanger has to go and the selection is done with a selector switch present Up to 300 hangers can be stored in the storage area that means around 600 frames and 600 body covers can be stored in the weld storage area From storage area hangers move to the unloading area and from unloading area these body covers and frames are loaded on to a Carrier which takes them to the paint section Unloading of the frames and body covers depends on the requirement of the assembly line and which model they are making according to their requirement unloading of model frames and body covers is done Unloading of the model is again done by the selector switch that is when there is requirement of model 1 the person who unloads the frame presses model switch and from storage model 1 moves to the unloading area Similarly when there is requirement of model 2 then operator presses model 2 switch and same goes for the model 3 when the requirement is of model 3 the operator presses the model 3 switch and then from storage model 3 moves to unloading bay

3 Top Coat

Loading In this process frames and body covers are mounted on the carrier of the conveyor line There are two lines for the paint that is paint A line and paint B line both the lines are very much important because in A line loading of frames and front body left right cover and rear body covers are loaded and on B line mudguard and front cowl is loaded and after loading of these parts then the carrier moves to the pretreatment zone

Pre-Treatment In pre-treatment degreasing and dust cleaning is done In pre-treatment bodies have to undergo two operations first wasting with the soft water by this process degreasing is done and all the dust particles are removed from the frames and body covers In general first we get hard water is converted to soft water by ion exchange mechanism

Secondly on bodies and frames phosphate cleaning is done by this method any dust particle or any grease particle left on the frames and body cover is removed

Electro-Deposition In electro deposition carrier which carries frame and body covers turn down into the electro deposition chamber and in electro deposition chamber is filled with the base paint or primer When carrier turns down it strikes high voltage wire and it gets negatively charged and become cathode and paint in the chamber becomes anode then a uniform thin film of base paint is deposited on

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 42

the body covers and frames of the scooter This process is repeated twice and after that it is passed to ED oven

ED Oven In electro deposition oven base coat done on the frame and body covers is heated to 150 degree temperature and this base coat is dried here and after that is passed to paint booth

Paint Booth Paint booth has three sections first one is sanding zone second primary coat or under coat and third is top coat

In sanding zone sanding of the frames and body covers is done and after that it is sent to under coat zone in under coat zone single coat of the paint is done on frames and body covers and in this zone coat of paint is done with the help of robots and after that frames and body covers then sent to top coat zone here in this zone second coat of the paint is done and this second coat of paint is done with the operator and after that these frames and body covers are sent to top coat oven

Top Coat Oven In top coat oven these frames and body covers are heated up to 170 degree temperature and dried and then allowed to cool naturally to room temperature and from there it is sent to the inspection zone

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 43

Inspection Zone In inspection zone body covers and frames have to pass infra-red zone Here IR testing machine checks for irregularities in the paint done and after that these body covers and frames are manually checked by hand for any errors in the paint jobs Parts which pass these tests get the OK mark and move to unloading area

Unloading In this area unloading of frames and body covers takes place Frames and body covers having OK mark are loaded to the paint body store and body covers and frames not having OK mark on them are sent to the repair work station and there they fix the problems which frames and body covers have They are then unloaded and then loaded on to the hanger and the parts go to the paint body storage In storage final or finished body covers and frames are stored which from storage area moves to the final assembly line

9 ProjectProject Definition

To study the various parts of the carrier being used in the paint shop and its problem analysis

Project Introduction

Carrier is defined as a thing which supports or holds up a part during its movement It is used to carry parts to the paint shop where various processes can be performed Carrier forms the basis of the Paint Shop because the movement of the parts from one point to another in the paint shop takes place only due to carrier The parts are loaded on the carrier with the help of a jig and then the motion takes place

Paint shop carrier is the most important moving part in the paint process Most problems and the breakdowns in the paint shop occur due to the carrier only It causes loss to the net production Bends or breaks due to load of body part applied on carrier causes distortions which ultimately results in the breakdown

Carrier is a part of the conveyer system being used in the paint shop The other components of the conveyer system are the prime mover drive (works as the input motion source for chain) chain and chain track carrier carrier turn (for turning the carrier) carrier

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 45

revolution (for revolving the carrier) stopper (it temporarily stops the carrier on line) carrier locks auto feeder cylinders and drop lifters which support the motion of carrier

Part Description Of Carrier

Rail

Rail can be of two types ie pre rail and power rail Pre rail is used to drive trolley of the carrier Power rail is used to drive the conveyer system

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 46

Gear Box

Gear Box acts as a Speed Reducer It consists of a worm and worm-wheel arrangement which turns the axis of rotation by 90deg and reduces the speed of the parts The gear box is coupled with the small sprocket Gear transmits power to small sprocket which helps for carrier turn this is also called as reduction gear The relation between the torque and diameter of worm shaft is given by

T (Kg-m) = π16dsup3τ

where τ is the twisting moment

Problem Analysis Of Carrier

Frame Hole NG

During the motion of the carrier when it is suddenly stopped by the stopper vibrations are produced in it and the pin inserted in the hole of the frame enlarges the size of the hole thereby causing the problem of frame hole NG

To reduce this problem an anti back-up system is applied to reduce the vibrations The NG frame hole is repaired by welding a bush at the site of the hole which is a newly developed Kaizen

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 64

Problems Caused By Loading

Improper loading of the frame body on the carrier damages the insulator collar because an unbalanced force acts upon it and insulator collars being the non-metallic parts are severely affected

R is the resultant vector

This is a production problem which causes the bending of jigs unbalancing of the carrier thereby causing improper motion at the carrier turns and revolutions and also resulting in the body parts falling in the oven

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 65

Gear Box Failure

Gear box of the carrier also fails some time due to overloading or improper coupling

Bending of Striker

Overloading at CTs and CRs causes the bending of the strikers which result in altered motion of the carrier

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 66

Breaking of Post

The post of the carrier can be broken due to variable and unbalanced load acting on the carrier The stresses are developed in the post which leads to its breaking Moreover hammering of the nut for the proper locking can also cause the breaking of nut

Overloading

Overloading is the state when the load on a part of the carrier is higher than its tolerance value Its causes are

If any object interrupts the motion of chain chain is not able to move forward properly causing overloading of chain

Improper position of the jig may lead to unbalancing of the carrier and overload may occur

Guide pin may not properly interact with the arm which may lead to non-alignment

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 67

Chain of the carrier turn may not be in proper position leading to overload at CT

Breaking of any of the carrier dogs will lead to improper revolution of the carrier

Other Problems

Cable breaks -gt Current does not reach to body part

ED COLLECTER burns out -gt It would not collect current

Threading of endndashplate striker wear out -gt Striker would not hit limit switch

Bush between coupling is cut

Bearing sometimes disrupts system

Swivel pipe bends -gt Carrier wouldnrsquot be leveled

Insulator sometimes fails to stop current

End plate threading wears

Spindle shaft bends -gt Carrier wouldnrsquot be leveled

Striker and arm also bends

Conclusion

From my project of one month here in HMSI I came to know that how

work goes on in the organization As far as my project of study

maintenance and breakdown analysis of carrier is concerned I came to

know the importance of carrier in paint shop and the production

problems caused by the carrier in the industry The carrier being used in

the paint shop is the best possible system for proper painting of parts

By knowing the various specifications problems related to it can be

solved

8 Introduction to Maintenance Department

Introduction The maintenance department is one of the most important departments of the organization where the organization has its own production Maintenance department of Honda Motorcycle and Scooter India Private Limited (HMSI) is a responsible for all the breakdowns which occur in the machines or where there is any production loss so when to overcome the problem of production loss maintenance team has to work efficiently so that there is no mistake committed by them by which production loss occurs

Some important definitions used by maintenance

Maintenance Action necessary for retaining or restoring an equipment machine or system to the specified operable condition to achieve its maximum useful life It includes planned and preventive maintenance

Planned Maintenance Preventive maintenance carried out according to a fixed plan is called planned maintenance

Preventive Maintenance Systematic inspection detection correction and prevention of incipient failures before they become actual or major failures is called as preventive maintenance

Breakdown Maintenance Repair or replacements performed after a machine has failed to return to its functional state following a malfunction or shutdown is called as breakdown maintenance

Predictive Maintenance Type of preventive maintenance performed continuously or at interval according to the requirement to diagnose and

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 36

monitor a condition or system also called condition based maintenance is called as predictive maintenance

Mean Time To Repair (MTTR) Basic measure of maintainability of repairable items it represents the average mean time required to repair a failed component or device is defined as mean time to repair

Mean Time Between Failures (MTBF) Basic measure of the reliability of repairable items it represents the average number of a life units during which all parts of a device or system perform within their specified limits under specified conditions are called as mean time between failures

Down Time Period during which an equipment or machine is not functional or cannot work It may be due to technical failures mechanical adjustments maintenance or non availability of inputs such as materials labor and power etc is called as down time

Frame Maintenance In this department there are three sections

1 Press Section

2 Weld Section

3 Paint Section

PRESS SECTION Press section has mainly four machines

Komatsu Pressndash3

AIDA Press -1

CNC bending machine

Hind Press

These presses are mechanical presses and on this press mudguard fuel tank nose and body cover of the scooters like activa aviator dio shine twister unicorn and twister Process like blanking coining and bending of pipes is done

Blanking is cutting up a large sheer of stock into smaller pieces suitable for next operation

Coining is the process of removal of extra material or to make work piece up to the limit All these mechanical presses are of 500 ton and there only one hydraulic press and this press are used to repair the dyes

CNC pipe bending machines are used to bend the pipes which later used in the manufacturing of the frame

WELDING SECTION In welding section there are six types of welding machines used in manufacturing of frames and body covers

1 Gantry System Gantry system is a system in which gantry crane is used for transporting the frame and welding is done by the robots and welding is finished by the robots the gantry crane picks up the frame and body covers and puts them on the conveyer or the hanger which goes to the weld body storage On gantry system seam welding is done on the body covers and on the frames with the help of the welding robots This system is fully automatic and there is no involvement of human being it picks up the frame and body covers from the location defined to it then does all the processing on it and then passes it to the conveyer

2 MIG Welding Metal inert gas welding in this inert gas argon is used and argon acts as a shielding gas 1-5 oxygen is used This type of welding uses consumable wire electrode during the welding process that is fed from the wire spool MIG welding has some advantages over the other welding techniques It provides a uniform weld it provides a slag free weld beam and needs little clean up

3 Spot Welding Spot welding is a process in which contacting metal surface are joined by the heat obtained from resistance to electric flow and this type of welding is done on the body covers of the scooter

4 Seam Welding It is a process that welds at a surface of overlapped parts along a length of a joint Weld made by overlapping nuggets this type of welding is done on the fuel tanks and mudguards of scooter

5 Portable Spot Welding It is a portable gun which can be taken to specified range where other spot welding machine faces difficulty in welding This type of the welding is done on body covers of scooters

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 39

6 Fine Boring Fine boring is done on the frame where handle has to fit after fine boring handle is attached to it

When various operation of the welding on the different components of the scooter that is frame mudguard body covers and fuel tank is over then this welded body parts are loaded on to a conveyer hanger which takes these body parts to the weld body storage and in the weld body storage and in weld body storage there are three sections one for model 1 one for model 2 and the last for model 3 When welded body is loaded on to a conveyor then the person who loads these bodies on to the hanger select in which model hanger has to go and the selection is done with a selector switch present Up to 300 hangers can be stored in the storage area that means around 600 frames and 600 body covers can be stored in the weld storage area From storage area hangers move to the unloading area and from unloading area these body covers and frames are loaded on to a Carrier which takes them to the paint section Unloading of the frames and body covers depends on the requirement of the assembly line and which model they are making according to their requirement unloading of model frames and body covers is done Unloading of the model is again done by the selector switch that is when there is requirement of model 1 the person who unloads the frame presses model switch and from storage model 1 moves to the unloading area Similarly when there is requirement of model 2 then operator presses model 2 switch and same goes for the model 3 when the requirement is of model 3 the operator presses the model 3 switch and then from storage model 3 moves to unloading bay

PAINT SECTION Paint section is very important section In this section different treatments are done on the body covers and frames and it is a step by step process done as follows

Loading

Pre-Treatment

Electro-Deposition

ED Oven

Booth

Top Coat Oven

Inspection Zone

Unloading

PAINT PROCESS FLOW

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 41

1 Sanding Zone

2 Under Coat

3 Top Coat

Loading In this process frames and body covers are mounted on the carrier of the conveyor line There are two lines for the paint that is paint A line and paint B line both the lines are very much important because in A line loading of frames and front body left right cover and rear body covers are loaded and on B line mudguard and front cowl is loaded and after loading of these parts then the carrier moves to the pretreatment zone

Pre-Treatment In pre-treatment degreasing and dust cleaning is done In pre-treatment bodies have to undergo two operations first wasting with the soft water by this process degreasing is done and all the dust particles are removed from the frames and body covers In general first we get hard water is converted to soft water by ion exchange mechanism

Secondly on bodies and frames phosphate cleaning is done by this method any dust particle or any grease particle left on the frames and body cover is removed

Electro-Deposition In electro deposition carrier which carries frame and body covers turn down into the electro deposition chamber and in electro deposition chamber is filled with the base paint or primer When carrier turns down it strikes high voltage wire and it gets negatively charged and become cathode and paint in the chamber becomes anode then a uniform thin film of base paint is deposited on

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 42

the body covers and frames of the scooter This process is repeated twice and after that it is passed to ED oven

ED Oven In electro deposition oven base coat done on the frame and body covers is heated to 150 degree temperature and this base coat is dried here and after that is passed to paint booth

Paint Booth Paint booth has three sections first one is sanding zone second primary coat or under coat and third is top coat

In sanding zone sanding of the frames and body covers is done and after that it is sent to under coat zone in under coat zone single coat of the paint is done on frames and body covers and in this zone coat of paint is done with the help of robots and after that frames and body covers then sent to top coat zone here in this zone second coat of the paint is done and this second coat of paint is done with the operator and after that these frames and body covers are sent to top coat oven

Top Coat Oven In top coat oven these frames and body covers are heated up to 170 degree temperature and dried and then allowed to cool naturally to room temperature and from there it is sent to the inspection zone

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 43

Inspection Zone In inspection zone body covers and frames have to pass infra-red zone Here IR testing machine checks for irregularities in the paint done and after that these body covers and frames are manually checked by hand for any errors in the paint jobs Parts which pass these tests get the OK mark and move to unloading area

Unloading In this area unloading of frames and body covers takes place Frames and body covers having OK mark are loaded to the paint body store and body covers and frames not having OK mark on them are sent to the repair work station and there they fix the problems which frames and body covers have They are then unloaded and then loaded on to the hanger and the parts go to the paint body storage In storage final or finished body covers and frames are stored which from storage area moves to the final assembly line

9 ProjectProject Definition

To study the various parts of the carrier being used in the paint shop and its problem analysis

Project Introduction

Carrier is defined as a thing which supports or holds up a part during its movement It is used to carry parts to the paint shop where various processes can be performed Carrier forms the basis of the Paint Shop because the movement of the parts from one point to another in the paint shop takes place only due to carrier The parts are loaded on the carrier with the help of a jig and then the motion takes place

Paint shop carrier is the most important moving part in the paint process Most problems and the breakdowns in the paint shop occur due to the carrier only It causes loss to the net production Bends or breaks due to load of body part applied on carrier causes distortions which ultimately results in the breakdown

Carrier is a part of the conveyer system being used in the paint shop The other components of the conveyer system are the prime mover drive (works as the input motion source for chain) chain and chain track carrier carrier turn (for turning the carrier) carrier

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 45

revolution (for revolving the carrier) stopper (it temporarily stops the carrier on line) carrier locks auto feeder cylinders and drop lifters which support the motion of carrier

Part Description Of Carrier

Rail

Rail can be of two types ie pre rail and power rail Pre rail is used to drive trolley of the carrier Power rail is used to drive the conveyer system

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 46

Gear Box

Gear Box acts as a Speed Reducer It consists of a worm and worm-wheel arrangement which turns the axis of rotation by 90deg and reduces the speed of the parts The gear box is coupled with the small sprocket Gear transmits power to small sprocket which helps for carrier turn this is also called as reduction gear The relation between the torque and diameter of worm shaft is given by

T (Kg-m) = π16dsup3τ

where τ is the twisting moment

Velocity Ratio = 160

Tensile Strength of Material = 60 Kgmmsup2

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 47

Trolley

There are two trolleys present in a carrier namely Front and the Rear Trolley Front Trolley stops the carrier at a specified position by the actuation of stopper while Rear Trolley stops the next carrier by engaging with the Front trolley of next carrier Trolley Wheel contains ball bearings The outer race serves as a wheel A grease fitting is installed as a greasing port Guide Roller is installed to reduce friction against free rail Pivoting Dog is lifted by the own weight The chain pusher engages to the Pivoting dog for transport To stop the carrier the stopper (installed on the line) pushes down the Pivoting Dog to release the engagement with the pusher

Swivel Pipe

Swivel pipe is used to drive carrier during carrier revolution Swivel pipe is connected to the shaft of worm gear thus it also gets its power from the gear box

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 48

Problem Analysis Of Carrier

Frame Hole NG

During the motion of the carrier when it is suddenly stopped by the stopper vibrations are produced in it and the pin inserted in the hole of the frame enlarges the size of the hole thereby causing the problem of frame hole NG

To reduce this problem an anti back-up system is applied to reduce the vibrations The NG frame hole is repaired by welding a bush at the site of the hole which is a newly developed Kaizen

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 64

Problems Caused By Loading

Improper loading of the frame body on the carrier damages the insulator collar because an unbalanced force acts upon it and insulator collars being the non-metallic parts are severely affected

R is the resultant vector

This is a production problem which causes the bending of jigs unbalancing of the carrier thereby causing improper motion at the carrier turns and revolutions and also resulting in the body parts falling in the oven

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 65

Gear Box Failure

Gear box of the carrier also fails some time due to overloading or improper coupling

Bending of Striker

Overloading at CTs and CRs causes the bending of the strikers which result in altered motion of the carrier

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 66

Breaking of Post

The post of the carrier can be broken due to variable and unbalanced load acting on the carrier The stresses are developed in the post which leads to its breaking Moreover hammering of the nut for the proper locking can also cause the breaking of nut

Overloading

Overloading is the state when the load on a part of the carrier is higher than its tolerance value Its causes are

If any object interrupts the motion of chain chain is not able to move forward properly causing overloading of chain

Improper position of the jig may lead to unbalancing of the carrier and overload may occur

Guide pin may not properly interact with the arm which may lead to non-alignment

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 67

Chain of the carrier turn may not be in proper position leading to overload at CT

Breaking of any of the carrier dogs will lead to improper revolution of the carrier

Other Problems

Cable breaks -gt Current does not reach to body part

ED COLLECTER burns out -gt It would not collect current

Threading of endndashplate striker wear out -gt Striker would not hit limit switch

Bush between coupling is cut

Bearing sometimes disrupts system

Swivel pipe bends -gt Carrier wouldnrsquot be leveled

Insulator sometimes fails to stop current

End plate threading wears

Spindle shaft bends -gt Carrier wouldnrsquot be leveled

Striker and arm also bends

Conclusion

From my project of one month here in HMSI I came to know that how

work goes on in the organization As far as my project of study

maintenance and breakdown analysis of carrier is concerned I came to

know the importance of carrier in paint shop and the production

problems caused by the carrier in the industry The carrier being used in

the paint shop is the best possible system for proper painting of parts

By knowing the various specifications problems related to it can be

solved

8 Introduction to Maintenance Department

Introduction The maintenance department is one of the most important departments of the organization where the organization has its own production Maintenance department of Honda Motorcycle and Scooter India Private Limited (HMSI) is a responsible for all the breakdowns which occur in the machines or where there is any production loss so when to overcome the problem of production loss maintenance team has to work efficiently so that there is no mistake committed by them by which production loss occurs

Some important definitions used by maintenance

Maintenance Action necessary for retaining or restoring an equipment machine or system to the specified operable condition to achieve its maximum useful life It includes planned and preventive maintenance

Planned Maintenance Preventive maintenance carried out according to a fixed plan is called planned maintenance

Preventive Maintenance Systematic inspection detection correction and prevention of incipient failures before they become actual or major failures is called as preventive maintenance

Breakdown Maintenance Repair or replacements performed after a machine has failed to return to its functional state following a malfunction or shutdown is called as breakdown maintenance

Predictive Maintenance Type of preventive maintenance performed continuously or at interval according to the requirement to diagnose and

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 36

monitor a condition or system also called condition based maintenance is called as predictive maintenance

Mean Time To Repair (MTTR) Basic measure of maintainability of repairable items it represents the average mean time required to repair a failed component or device is defined as mean time to repair

Mean Time Between Failures (MTBF) Basic measure of the reliability of repairable items it represents the average number of a life units during which all parts of a device or system perform within their specified limits under specified conditions are called as mean time between failures

Down Time Period during which an equipment or machine is not functional or cannot work It may be due to technical failures mechanical adjustments maintenance or non availability of inputs such as materials labor and power etc is called as down time

Frame Maintenance In this department there are three sections

1 Press Section

2 Weld Section

Engine Maintenance Frame Maintenance

3 Paint Section

PRESS SECTION Press section has mainly four machines

Komatsu Pressndash3

AIDA Press -1

CNC bending machine

Hind Press

These presses are mechanical presses and on this press mudguard fuel tank nose and body cover of the scooters like activa aviator dio shine twister unicorn and twister Process like blanking coining and bending of pipes is done

Blanking is cutting up a large sheer of stock into smaller pieces suitable for next operation

Coining is the process of removal of extra material or to make work piece up to the limit All these mechanical presses are of 500 ton and there only one hydraulic press and this press are used to repair the dyes

CNC pipe bending machines are used to bend the pipes which later used in the manufacturing of the frame

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 38

WELDING SECTION In welding section there are six types of welding machines used in manufacturing of frames and body covers

1 Gantry System Gantry system is a system in which gantry crane is used for transporting the frame and welding is done by the robots and welding is finished by the robots the gantry crane picks up the frame and body covers and puts them on the conveyer or the hanger which goes to the weld body storage On gantry system seam welding is done on the body covers and on the frames with the help of the welding robots This system is fully automatic and there is no involvement of human being it picks up the frame and body covers from the location defined to it then does all the processing on it and then passes it to the conveyer

2 MIG Welding Metal inert gas welding in this inert gas argon is used and argon acts as a shielding gas 1-5 oxygen is used This type of welding uses consumable wire electrode during the welding process that is fed from the wire spool MIG welding has some advantages over the other welding techniques It provides a uniform weld it provides a slag free weld beam and needs little clean up

3 Spot Welding Spot welding is a process in which contacting metal surface are joined by the heat obtained from resistance to electric flow and this type of welding is done on the body covers of the scooter

4 Seam Welding It is a process that welds at a surface of overlapped parts along a length of a joint Weld made by overlapping nuggets this type of welding is done on the fuel tanks and mudguards of scooter

5 Portable Spot Welding It is a portable gun which can be taken to specified range where other spot welding machine faces difficulty in welding This type of the welding is done on body covers of scooters

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 39

6 Fine Boring Fine boring is done on the frame where handle has to fit after fine boring handle is attached to it

When various operation of the welding on the different components of the scooter that is frame mudguard body covers and fuel tank is over then this welded body parts are loaded on to a conveyer hanger which takes these body parts to the weld body storage and in the weld body storage and in weld body storage there are three sections one for model 1 one for model 2 and the last for model 3 When welded body is loaded on to a conveyor then the person who loads these bodies on to the hanger select in which model hanger has to go and the selection is done with a selector switch present Up to 300 hangers can be stored in the storage area that means around 600 frames and 600 body covers can be stored in the weld storage area From storage area hangers move to the unloading area and from unloading area these body covers and frames are loaded on to a Carrier which takes them to the paint section Unloading of the frames and body covers depends on the requirement of the assembly line and which model they are making according to their requirement unloading of model frames and body covers is done Unloading of the model is again done by the selector switch that is when there is requirement of model 1 the person who unloads the frame presses model switch and from storage model 1 moves to the unloading area Similarly when there is requirement of model 2 then operator presses model 2 switch and same goes for the model 3 when the requirement is of model 3 the operator presses the model 3 switch and then from storage model 3 moves to unloading bay

PAINT SECTION Paint section is very important section In this section different treatments are done on the body covers and frames and it is a step by step process done as follows

Loading

Pre-Treatment

Electro-Deposition

ED Oven

Booth

Top Coat Oven

Inspection Zone

Unloading

PAINT PROCESS FLOW

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 41

1 Sanding Zone

2 Under Coat

3 Top Coat

Loading In this process frames and body covers are mounted on the carrier of the conveyor line There are two lines for the paint that is paint A line and paint B line both the lines are very much important because in A line loading of frames and front body left right cover and rear body covers are loaded and on B line mudguard and front cowl is loaded and after loading of these parts then the carrier moves to the pretreatment zone

Pre-Treatment In pre-treatment degreasing and dust cleaning is done In pre-treatment bodies have to undergo two operations first wasting with the soft water by this process degreasing is done and all the dust particles are removed from the frames and body covers In general first we get hard water is converted to soft water by ion exchange mechanism

Secondly on bodies and frames phosphate cleaning is done by this method any dust particle or any grease particle left on the frames and body cover is removed

Electro-Deposition In electro deposition carrier which carries frame and body covers turn down into the electro deposition chamber and in electro deposition chamber is filled with the base paint or primer When carrier turns down it strikes high voltage wire and it gets negatively charged and become cathode and paint in the chamber becomes anode then a uniform thin film of base paint is deposited on

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 42

the body covers and frames of the scooter This process is repeated twice and after that it is passed to ED oven

ED Oven In electro deposition oven base coat done on the frame and body covers is heated to 150 degree temperature and this base coat is dried here and after that is passed to paint booth

Paint Booth Paint booth has three sections first one is sanding zone second primary coat or under coat and third is top coat

In sanding zone sanding of the frames and body covers is done and after that it is sent to under coat zone in under coat zone single coat of the paint is done on frames and body covers and in this zone coat of paint is done with the help of robots and after that frames and body covers then sent to top coat zone here in this zone second coat of the paint is done and this second coat of paint is done with the operator and after that these frames and body covers are sent to top coat oven

Top Coat Oven In top coat oven these frames and body covers are heated up to 170 degree temperature and dried and then allowed to cool naturally to room temperature and from there it is sent to the inspection zone

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 43

Inspection Zone In inspection zone body covers and frames have to pass infra-red zone Here IR testing machine checks for irregularities in the paint done and after that these body covers and frames are manually checked by hand for any errors in the paint jobs Parts which pass these tests get the OK mark and move to unloading area

Unloading In this area unloading of frames and body covers takes place Frames and body covers having OK mark are loaded to the paint body store and body covers and frames not having OK mark on them are sent to the repair work station and there they fix the problems which frames and body covers have They are then unloaded and then loaded on to the hanger and the parts go to the paint body storage In storage final or finished body covers and frames are stored which from storage area moves to the final assembly line

9 ProjectProject Definition

To study the various parts of the carrier being used in the paint shop and its problem analysis

Project Introduction

Carrier is defined as a thing which supports or holds up a part during its movement It is used to carry parts to the paint shop where various processes can be performed Carrier forms the basis of the Paint Shop because the movement of the parts from one point to another in the paint shop takes place only due to carrier The parts are loaded on the carrier with the help of a jig and then the motion takes place

Paint shop carrier is the most important moving part in the paint process Most problems and the breakdowns in the paint shop occur due to the carrier only It causes loss to the net production Bends or breaks due to load of body part applied on carrier causes distortions which ultimately results in the breakdown

Carrier is a part of the conveyer system being used in the paint shop The other components of the conveyer system are the prime mover drive (works as the input motion source for chain) chain and chain track carrier carrier turn (for turning the carrier) carrier

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 45

revolution (for revolving the carrier) stopper (it temporarily stops the carrier on line) carrier locks auto feeder cylinders and drop lifters which support the motion of carrier

Part Description Of Carrier

Rail

Rail can be of two types ie pre rail and power rail Pre rail is used to drive trolley of the carrier Power rail is used to drive the conveyer system

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 46

Gear Box

Gear Box acts as a Speed Reducer It consists of a worm and worm-wheel arrangement which turns the axis of rotation by 90deg and reduces the speed of the parts The gear box is coupled with the small sprocket Gear transmits power to small sprocket which helps for carrier turn this is also called as reduction gear The relation between the torque and diameter of worm shaft is given by

T (Kg-m) = π16dsup3τ

where τ is the twisting moment

Velocity Ratio = 160

Tensile Strength of Material = 60 Kgmmsup2

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 47

Trolley

Problem Analysis Of Carrier

Frame Hole NG

During the motion of the carrier when it is suddenly stopped by the stopper vibrations are produced in it and the pin inserted in the hole of the frame enlarges the size of the hole thereby causing the problem of frame hole NG

To reduce this problem an anti back-up system is applied to reduce the vibrations The NG frame hole is repaired by welding a bush at the site of the hole which is a newly developed Kaizen

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 64

Problems Caused By Loading

Improper loading of the frame body on the carrier damages the insulator collar because an unbalanced force acts upon it and insulator collars being the non-metallic parts are severely affected

R is the resultant vector

This is a production problem which causes the bending of jigs unbalancing of the carrier thereby causing improper motion at the carrier turns and revolutions and also resulting in the body parts falling in the oven

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 65

Gear Box Failure

Gear box of the carrier also fails some time due to overloading or improper coupling

Bending of Striker

Overloading at CTs and CRs causes the bending of the strikers which result in altered motion of the carrier

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 66

Breaking of Post

The post of the carrier can be broken due to variable and unbalanced load acting on the carrier The stresses are developed in the post which leads to its breaking Moreover hammering of the nut for the proper locking can also cause the breaking of nut

Overloading

Overloading is the state when the load on a part of the carrier is higher than its tolerance value Its causes are

If any object interrupts the motion of chain chain is not able to move forward properly causing overloading of chain

Improper position of the jig may lead to unbalancing of the carrier and overload may occur

Guide pin may not properly interact with the arm which may lead to non-alignment

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 67

Chain of the carrier turn may not be in proper position leading to overload at CT

Breaking of any of the carrier dogs will lead to improper revolution of the carrier

Other Problems

Cable breaks -gt Current does not reach to body part

ED COLLECTER burns out -gt It would not collect current

Threading of endndashplate striker wear out -gt Striker would not hit limit switch

Bush between coupling is cut

Bearing sometimes disrupts system

Swivel pipe bends -gt Carrier wouldnrsquot be leveled

Insulator sometimes fails to stop current

End plate threading wears

Spindle shaft bends -gt Carrier wouldnrsquot be leveled

Striker and arm also bends

8 Introduction to Maintenance Department

Introduction The maintenance department is one of the most important departments of the organization where the organization has its own production Maintenance department of Honda Motorcycle and Scooter India Private Limited (HMSI) is a responsible for all the breakdowns which occur in the machines or where there is any production loss so when to overcome the problem of production loss maintenance team has to work efficiently so that there is no mistake committed by them by which production loss occurs

Some important definitions used by maintenance

Maintenance Action necessary for retaining or restoring an equipment machine or system to the specified operable condition to achieve its maximum useful life It includes planned and preventive maintenance

Planned Maintenance Preventive maintenance carried out according to a fixed plan is called planned maintenance

Preventive Maintenance Systematic inspection detection correction and prevention of incipient failures before they become actual or major failures is called as preventive maintenance

Breakdown Maintenance Repair or replacements performed after a machine has failed to return to its functional state following a malfunction or shutdown is called as breakdown maintenance

Predictive Maintenance Type of preventive maintenance performed continuously or at interval according to the requirement to diagnose and

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 36

monitor a condition or system also called condition based maintenance is called as predictive maintenance

Mean Time To Repair (MTTR) Basic measure of maintainability of repairable items it represents the average mean time required to repair a failed component or device is defined as mean time to repair

Mean Time Between Failures (MTBF) Basic measure of the reliability of repairable items it represents the average number of a life units during which all parts of a device or system perform within their specified limits under specified conditions are called as mean time between failures

Down Time Period during which an equipment or machine is not functional or cannot work It may be due to technical failures mechanical adjustments maintenance or non availability of inputs such as materials labor and power etc is called as down time

Frame Maintenance In this department there are three sections

1 Press Section

2 Weld Section

3 Paint Section

PRESS SECTION Press section has mainly four machines

Komatsu Pressndash3

AIDA Press -1

CNC bending machine

Hind Press

These presses are mechanical presses and on this press mudguard fuel tank nose and body cover of the scooters like activa aviator dio shine twister unicorn and twister Process like blanking coining and bending of pipes is done

Blanking is cutting up a large sheer of stock into smaller pieces suitable for next operation

Coining is the process of removal of extra material or to make work piece up to the limit All these mechanical presses are of 500 ton and there only one hydraulic press and this press are used to repair the dyes

CNC pipe bending machines are used to bend the pipes which later used in the manufacturing of the frame

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 38

WELDING SECTION In welding section there are six types of welding machines used in manufacturing of frames and body covers

1 Gantry System Gantry system is a system in which gantry crane is used for transporting the frame and welding is done by the robots and welding is finished by the robots the gantry crane picks up the frame and body covers and puts them on the conveyer or the hanger which goes to the weld body storage On gantry system seam welding is done on the body covers and on the frames with the help of the welding robots This system is fully automatic and there is no involvement of human being it picks up the frame and body covers from the location defined to it then does all the processing on it and then passes it to the conveyer

2 MIG Welding Metal inert gas welding in this inert gas argon is used and argon acts as a shielding gas 1-5 oxygen is used This type of welding uses consumable wire electrode during the welding process that is fed from the wire spool MIG welding has some advantages over the other welding techniques It provides a uniform weld it provides a slag free weld beam and needs little clean up

3 Spot Welding Spot welding is a process in which contacting metal surface are joined by the heat obtained from resistance to electric flow and this type of welding is done on the body covers of the scooter

4 Seam Welding It is a process that welds at a surface of overlapped parts along a length of a joint Weld made by overlapping nuggets this type of welding is done on the fuel tanks and mudguards of scooter

5 Portable Spot Welding It is a portable gun which can be taken to specified range where other spot welding machine faces difficulty in welding This type of the welding is done on body covers of scooters

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 39

6 Fine Boring Fine boring is done on the frame where handle has to fit after fine boring handle is attached to it

When various operation of the welding on the different components of the scooter that is frame mudguard body covers and fuel tank is over then this welded body parts are loaded on to a conveyer hanger which takes these body parts to the weld body storage and in the weld body storage and in weld body storage there are three sections one for model 1 one for model 2 and the last for model 3 When welded body is loaded on to a conveyor then the person who loads these bodies on to the hanger select in which model hanger has to go and the selection is done with a selector switch present Up to 300 hangers can be stored in the storage area that means around 600 frames and 600 body covers can be stored in the weld storage area From storage area hangers move to the unloading area and from unloading area these body covers and frames are loaded on to a Carrier which takes them to the paint section Unloading of the frames and body covers depends on the requirement of the assembly line and which model they are making according to their requirement unloading of model frames and body covers is done Unloading of the model is again done by the selector switch that is when there is requirement of model 1 the person who unloads the frame presses model switch and from storage model 1 moves to the unloading area Similarly when there is requirement of model 2 then operator presses model 2 switch and same goes for the model 3 when the requirement is of model 3 the operator presses the model 3 switch and then from storage model 3 moves to unloading bay

1 Sanding Zone

2 Under Coat

3 Top Coat

Loading In this process frames and body covers are mounted on the carrier of the conveyor line There are two lines for the paint that is paint A line and paint B line both the lines are very much important because in A line loading of frames and front body left right cover and rear body covers are loaded and on B line mudguard and front cowl is loaded and after loading of these parts then the carrier moves to the pretreatment zone

Pre-Treatment In pre-treatment degreasing and dust cleaning is done In pre-treatment bodies have to undergo two operations first wasting with the soft water by this process degreasing is done and all the dust particles are removed from the frames and body covers In general first we get hard water is converted to soft water by ion exchange mechanism

Secondly on bodies and frames phosphate cleaning is done by this method any dust particle or any grease particle left on the frames and body cover is removed

Electro-Deposition In electro deposition carrier which carries frame and body covers turn down into the electro deposition chamber and in electro deposition chamber is filled with the base paint or primer When carrier turns down it strikes high voltage wire and it gets negatively charged and become cathode and paint in the chamber becomes anode then a uniform thin film of base paint is deposited on

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 42

the body covers and frames of the scooter This process is repeated twice and after that it is passed to ED oven

ED Oven In electro deposition oven base coat done on the frame and body covers is heated to 150 degree temperature and this base coat is dried here and after that is passed to paint booth

Paint Booth Paint booth has three sections first one is sanding zone second primary coat or under coat and third is top coat

In sanding zone sanding of the frames and body covers is done and after that it is sent to under coat zone in under coat zone single coat of the paint is done on frames and body covers and in this zone coat of paint is done with the help of robots and after that frames and body covers then sent to top coat zone here in this zone second coat of the paint is done and this second coat of paint is done with the operator and after that these frames and body covers are sent to top coat oven

Top Coat Oven In top coat oven these frames and body covers are heated up to 170 degree temperature and dried and then allowed to cool naturally to room temperature and from there it is sent to the inspection zone

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 43

Inspection Zone In inspection zone body covers and frames have to pass infra-red zone Here IR testing machine checks for irregularities in the paint done and after that these body covers and frames are manually checked by hand for any errors in the paint jobs Parts which pass these tests get the OK mark and move to unloading area

Unloading In this area unloading of frames and body covers takes place Frames and body covers having OK mark are loaded to the paint body store and body covers and frames not having OK mark on them are sent to the repair work station and there they fix the problems which frames and body covers have They are then unloaded and then loaded on to the hanger and the parts go to the paint body storage In storage final or finished body covers and frames are stored which from storage area moves to the final assembly line

9 ProjectProject Definition

To study the various parts of the carrier being used in the paint shop and its problem analysis

Project Introduction

Carrier is defined as a thing which supports or holds up a part during its movement It is used to carry parts to the paint shop where various processes can be performed Carrier forms the basis of the Paint Shop because the movement of the parts from one point to another in the paint shop takes place only due to carrier The parts are loaded on the carrier with the help of a jig and then the motion takes place

Paint shop carrier is the most important moving part in the paint process Most problems and the breakdowns in the paint shop occur due to the carrier only It causes loss to the net production Bends or breaks due to load of body part applied on carrier causes distortions which ultimately results in the breakdown

Carrier is a part of the conveyer system being used in the paint shop The other components of the conveyer system are the prime mover drive (works as the input motion source for chain) chain and chain track carrier carrier turn (for turning the carrier) carrier

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 45

revolution (for revolving the carrier) stopper (it temporarily stops the carrier on line) carrier locks auto feeder cylinders and drop lifters which support the motion of carrier

Part Description Of Carrier

Rail

Rail can be of two types ie pre rail and power rail Pre rail is used to drive trolley of the carrier Power rail is used to drive the conveyer system

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 46

Gear Box

Gear Box acts as a Speed Reducer It consists of a worm and worm-wheel arrangement which turns the axis of rotation by 90deg and reduces the speed of the parts The gear box is coupled with the small sprocket Gear transmits power to small sprocket which helps for carrier turn this is also called as reduction gear The relation between the torque and diameter of worm shaft is given by

T (Kg-m) = π16dsup3τ

where τ is the twisting moment

Velocity Ratio = 160

Tensile Strength of Material = 60 Kgmmsup2

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 47

Trolley

There are two trolleys present in a carrier namely Front and the Rear Trolley Front Trolley stops the carrier at a specified position by the actuation of stopper while Rear Trolley stops the next carrier by engaging with the Front trolley of next carrier Trolley Wheel contains ball bearings The outer race serves as a wheel A grease fitting is installed as a greasing port Guide Roller is installed to reduce friction against free rail Pivoting Dog is lifted by the own weight The chain pusher engages to the Pivoting dog for transport To stop the carrier the stopper (installed on the line) pushes down the Pivoting Dog to release the engagement with the pusher

Swivel Pipe

Swivel pipe is used to drive carrier during carrier revolution Swivel pipe is connected to the shaft of worm gear thus it also gets its power from the gear box

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 48

Problem Analysis Of Carrier

Frame Hole NG

During the motion of the carrier when it is suddenly stopped by the stopper vibrations are produced in it and the pin inserted in the hole of the frame enlarges the size of the hole thereby causing the problem of frame hole NG

To reduce this problem an anti back-up system is applied to reduce the vibrations The NG frame hole is repaired by welding a bush at the site of the hole which is a newly developed Kaizen

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 64

Problems Caused By Loading

Improper loading of the frame body on the carrier damages the insulator collar because an unbalanced force acts upon it and insulator collars being the non-metallic parts are severely affected

R is the resultant vector

This is a production problem which causes the bending of jigs unbalancing of the carrier thereby causing improper motion at the carrier turns and revolutions and also resulting in the body parts falling in the oven

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 65

Gear Box Failure

Gear box of the carrier also fails some time due to overloading or improper coupling

Bending of Striker

Overloading at CTs and CRs causes the bending of the strikers which result in altered motion of the carrier

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 66

Breaking of Post

The post of the carrier can be broken due to variable and unbalanced load acting on the carrier The stresses are developed in the post which leads to its breaking Moreover hammering of the nut for the proper locking can also cause the breaking of nut

Overloading

Overloading is the state when the load on a part of the carrier is higher than its tolerance value Its causes are

If any object interrupts the motion of chain chain is not able to move forward properly causing overloading of chain

Improper position of the jig may lead to unbalancing of the carrier and overload may occur

Guide pin may not properly interact with the arm which may lead to non-alignment

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 67

Chain of the carrier turn may not be in proper position leading to overload at CT

Breaking of any of the carrier dogs will lead to improper revolution of the carrier

Other Problems

Cable breaks -gt Current does not reach to body part

ED COLLECTER burns out -gt It would not collect current

Threading of endndashplate striker wear out -gt Striker would not hit limit switch

Bush between coupling is cut

Bearing sometimes disrupts system

Swivel pipe bends -gt Carrier wouldnrsquot be leveled

Insulator sometimes fails to stop current

End plate threading wears

Spindle shaft bends -gt Carrier wouldnrsquot be leveled

Striker and arm also bends

8 Introduction to Maintenance Department

Introduction The maintenance department is one of the most important departments of the organization where the organization has its own production Maintenance department of Honda Motorcycle and Scooter India Private Limited (HMSI) is a responsible for all the breakdowns which occur in the machines or where there is any production loss so when to overcome the problem of production loss maintenance team has to work efficiently so that there is no mistake committed by them by which production loss occurs

Some important definitions used by maintenance

Maintenance Action necessary for retaining or restoring an equipment machine or system to the specified operable condition to achieve its maximum useful life It includes planned and preventive maintenance

Planned Maintenance Preventive maintenance carried out according to a fixed plan is called planned maintenance

Preventive Maintenance Systematic inspection detection correction and prevention of incipient failures before they become actual or major failures is called as preventive maintenance

Breakdown Maintenance Repair or replacements performed after a machine has failed to return to its functional state following a malfunction or shutdown is called as breakdown maintenance

Predictive Maintenance Type of preventive maintenance performed continuously or at interval according to the requirement to diagnose and

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 36

monitor a condition or system also called condition based maintenance is called as predictive maintenance

Mean Time To Repair (MTTR) Basic measure of maintainability of repairable items it represents the average mean time required to repair a failed component or device is defined as mean time to repair

Mean Time Between Failures (MTBF) Basic measure of the reliability of repairable items it represents the average number of a life units during which all parts of a device or system perform within their specified limits under specified conditions are called as mean time between failures

Down Time Period during which an equipment or machine is not functional or cannot work It may be due to technical failures mechanical adjustments maintenance or non availability of inputs such as materials labor and power etc is called as down time

Frame Maintenance In this department there are three sections

1 Press Section

2 Weld Section

3 Paint Section

PRESS SECTION Press section has mainly four machines

Komatsu Pressndash3

AIDA Press -1

CNC bending machine

Hind Press

These presses are mechanical presses and on this press mudguard fuel tank nose and body cover of the scooters like activa aviator dio shine twister unicorn and twister Process like blanking coining and bending of pipes is done

Blanking is cutting up a large sheer of stock into smaller pieces suitable for next operation

Coining is the process of removal of extra material or to make work piece up to the limit All these mechanical presses are of 500 ton and there only one hydraulic press and this press are used to repair the dyes

CNC pipe bending machines are used to bend the pipes which later used in the manufacturing of the frame

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 38

WELDING SECTION In welding section there are six types of welding machines used in manufacturing of frames and body covers

1 Gantry System Gantry system is a system in which gantry crane is used for transporting the frame and welding is done by the robots and welding is finished by the robots the gantry crane picks up the frame and body covers and puts them on the conveyer or the hanger which goes to the weld body storage On gantry system seam welding is done on the body covers and on the frames with the help of the welding robots This system is fully automatic and there is no involvement of human being it picks up the frame and body covers from the location defined to it then does all the processing on it and then passes it to the conveyer

2 MIG Welding Metal inert gas welding in this inert gas argon is used and argon acts as a shielding gas 1-5 oxygen is used This type of welding uses consumable wire electrode during the welding process that is fed from the wire spool MIG welding has some advantages over the other welding techniques It provides a uniform weld it provides a slag free weld beam and needs little clean up

3 Spot Welding Spot welding is a process in which contacting metal surface are joined by the heat obtained from resistance to electric flow and this type of welding is done on the body covers of the scooter

4 Seam Welding It is a process that welds at a surface of overlapped parts along a length of a joint Weld made by overlapping nuggets this type of welding is done on the fuel tanks and mudguards of scooter

5 Portable Spot Welding It is a portable gun which can be taken to specified range where other spot welding machine faces difficulty in welding This type of the welding is done on body covers of scooters

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 39

6 Fine Boring Fine boring is done on the frame where handle has to fit after fine boring handle is attached to it

When various operation of the welding on the different components of the scooter that is frame mudguard body covers and fuel tank is over then this welded body parts are loaded on to a conveyer hanger which takes these body parts to the weld body storage and in the weld body storage and in weld body storage there are three sections one for model 1 one for model 2 and the last for model 3 When welded body is loaded on to a conveyor then the person who loads these bodies on to the hanger select in which model hanger has to go and the selection is done with a selector switch present Up to 300 hangers can be stored in the storage area that means around 600 frames and 600 body covers can be stored in the weld storage area From storage area hangers move to the unloading area and from unloading area these body covers and frames are loaded on to a Carrier which takes them to the paint section Unloading of the frames and body covers depends on the requirement of the assembly line and which model they are making according to their requirement unloading of model frames and body covers is done Unloading of the model is again done by the selector switch that is when there is requirement of model 1 the person who unloads the frame presses model switch and from storage model 1 moves to the unloading area Similarly when there is requirement of model 2 then operator presses model 2 switch and same goes for the model 3 when the requirement is of model 3 the operator presses the model 3 switch and then from storage model 3 moves to unloading bay

Loading In this process frames and body covers are mounted on the carrier of the conveyor line There are two lines for the paint that is paint A line and paint B line both the lines are very much important because in A line loading of frames and front body left right cover and rear body covers are loaded and on B line mudguard and front cowl is loaded and after loading of these parts then the carrier moves to the pretreatment zone

Pre-Treatment In pre-treatment degreasing and dust cleaning is done In pre-treatment bodies have to undergo two operations first wasting with the soft water by this process degreasing is done and all the dust particles are removed from the frames and body covers In general first we get hard water is converted to soft water by ion exchange mechanism

Secondly on bodies and frames phosphate cleaning is done by this method any dust particle or any grease particle left on the frames and body cover is removed

Electro-Deposition In electro deposition carrier which carries frame and body covers turn down into the electro deposition chamber and in electro deposition chamber is filled with the base paint or primer When carrier turns down it strikes high voltage wire and it gets negatively charged and become cathode and paint in the chamber becomes anode then a uniform thin film of base paint is deposited on

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 42

the body covers and frames of the scooter This process is repeated twice and after that it is passed to ED oven

ED Oven In electro deposition oven base coat done on the frame and body covers is heated to 150 degree temperature and this base coat is dried here and after that is passed to paint booth

Paint Booth Paint booth has three sections first one is sanding zone second primary coat or under coat and third is top coat

In sanding zone sanding of the frames and body covers is done and after that it is sent to under coat zone in under coat zone single coat of the paint is done on frames and body covers and in this zone coat of paint is done with the help of robots and after that frames and body covers then sent to top coat zone here in this zone second coat of the paint is done and this second coat of paint is done with the operator and after that these frames and body covers are sent to top coat oven

Top Coat Oven In top coat oven these frames and body covers are heated up to 170 degree temperature and dried and then allowed to cool naturally to room temperature and from there it is sent to the inspection zone

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 43

Inspection Zone In inspection zone body covers and frames have to pass infra-red zone Here IR testing machine checks for irregularities in the paint done and after that these body covers and frames are manually checked by hand for any errors in the paint jobs Parts which pass these tests get the OK mark and move to unloading area

Unloading In this area unloading of frames and body covers takes place Frames and body covers having OK mark are loaded to the paint body store and body covers and frames not having OK mark on them are sent to the repair work station and there they fix the problems which frames and body covers have They are then unloaded and then loaded on to the hanger and the parts go to the paint body storage In storage final or finished body covers and frames are stored which from storage area moves to the final assembly line

9 ProjectProject Definition

To study the various parts of the carrier being used in the paint shop and its problem analysis

Project Introduction

Carrier is defined as a thing which supports or holds up a part during its movement It is used to carry parts to the paint shop where various processes can be performed Carrier forms the basis of the Paint Shop because the movement of the parts from one point to another in the paint shop takes place only due to carrier The parts are loaded on the carrier with the help of a jig and then the motion takes place

Paint shop carrier is the most important moving part in the paint process Most problems and the breakdowns in the paint shop occur due to the carrier only It causes loss to the net production Bends or breaks due to load of body part applied on carrier causes distortions which ultimately results in the breakdown

Carrier is a part of the conveyer system being used in the paint shop The other components of the conveyer system are the prime mover drive (works as the input motion source for chain) chain and chain track carrier carrier turn (for turning the carrier) carrier

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 45

revolution (for revolving the carrier) stopper (it temporarily stops the carrier on line) carrier locks auto feeder cylinders and drop lifters which support the motion of carrier

Part Description Of Carrier

Rail

Rail can be of two types ie pre rail and power rail Pre rail is used to drive trolley of the carrier Power rail is used to drive the conveyer system

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 46

Gear Box

Gear Box acts as a Speed Reducer It consists of a worm and worm-wheel arrangement which turns the axis of rotation by 90deg and reduces the speed of the parts The gear box is coupled with the small sprocket Gear transmits power to small sprocket which helps for carrier turn this is also called as reduction gear The relation between the torque and diameter of worm shaft is given by

T (Kg-m) = π16dsup3τ

where τ is the twisting moment

Velocity Ratio = 160

Tensile Strength of Material = 60 Kgmmsup2

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 47

Trolley

There are two trolleys present in a carrier namely Front and the Rear Trolley Front Trolley stops the carrier at a specified position by the actuation of stopper while Rear Trolley stops the next carrier by engaging with the Front trolley of next carrier Trolley Wheel contains ball bearings The outer race serves as a wheel A grease fitting is installed as a greasing port Guide Roller is installed to reduce friction against free rail Pivoting Dog is lifted by the own weight The chain pusher engages to the Pivoting dog for transport To stop the carrier the stopper (installed on the line) pushes down the Pivoting Dog to release the engagement with the pusher

Swivel Pipe

Swivel pipe is used to drive carrier during carrier revolution Swivel pipe is connected to the shaft of worm gear thus it also gets its power from the gear box

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 48

Big Sprocket

It comes in contact with the chain of the carrier turn and is responsible for rotation of the carrier It is mounted on the spindle on which the pan cover is fixed Four carrier dogs are attached to it which control the rotation of the carrier Big sprocket is attached to the spindle shaft plate

Small Sprocket

It is attached to the shaft connected to gear box It comes in contact with the chain of carrier revolution and is responsible for the revolution of the carrier

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 49

Tension Spring

Spring is used to lock turning plate thus stopping carrier revolution It happens when there is no load on the spring But when the load is applied turning plate opens and hence carrier revolution occurs

Insulator Collar

It provides insulation to the carrier in ED process so that there is no current in the frame To avoid the flow of current in the rail of the conveyer system and to avoid damage to the whole system insulator collars are provided

Post

It is mounted on the pan cover and holds the jig by locking it at its position Post mainly has three parts post cover post spacer and post spacer

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 50

Coupling

Bush Coupling transfers the motion from small sprocket shaft to input shaft To avoid overloading at the gear box bush coupling is provided

Guide Pin Arm

It locks the turning of the Big Sprocket by elongating the spring connected to it It has three contact points one is the spring one touches the guide pin of the carrier turn and third is for the engagement and disengagement of big sprocket

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 51

ED Collector

ED collector is used to collect current during ED process and transmits it through the cables to the body parts

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 52

End Striker amp Turn Striker

They are used to control the turning and revolution of the carrier respectively While end striker controls the revolution of the carrier turn striker controls the rotation of the carrier

Problem Analysis Of Carrier

Frame Hole NG

During the motion of the carrier when it is suddenly stopped by the stopper vibrations are produced in it and the pin inserted in the hole of the frame enlarges the size of the hole thereby causing the problem of frame hole NG

To reduce this problem an anti back-up system is applied to reduce the vibrations The NG frame hole is repaired by welding a bush at the site of the hole which is a newly developed Kaizen

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 64

Problems Caused By Loading

Improper loading of the frame body on the carrier damages the insulator collar because an unbalanced force acts upon it and insulator collars being the non-metallic parts are severely affected

R is the resultant vector

This is a production problem which causes the bending of jigs unbalancing of the carrier thereby causing improper motion at the carrier turns and revolutions and also resulting in the body parts falling in the oven

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 65

Gear Box Failure

Gear box of the carrier also fails some time due to overloading or improper coupling

Bending of Striker

Overloading at CTs and CRs causes the bending of the strikers which result in altered motion of the carrier

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 66

Breaking of Post

The post of the carrier can be broken due to variable and unbalanced load acting on the carrier The stresses are developed in the post which leads to its breaking Moreover hammering of the nut for the proper locking can also cause the breaking of nut

Overloading

Overloading is the state when the load on a part of the carrier is higher than its tolerance value Its causes are

If any object interrupts the motion of chain chain is not able to move forward properly causing overloading of chain

Improper position of the jig may lead to unbalancing of the carrier and overload may occur

Guide pin may not properly interact with the arm which may lead to non-alignment

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 67

Chain of the carrier turn may not be in proper position leading to overload at CT

Breaking of any of the carrier dogs will lead to improper revolution of the carrier

Other Problems

Cable breaks -gt Current does not reach to body part

ED COLLECTER burns out -gt It would not collect current

Threading of endndashplate striker wear out -gt Striker would not hit limit switch

Bush between coupling is cut

Bearing sometimes disrupts system

Swivel pipe bends -gt Carrier wouldnrsquot be leveled

Insulator sometimes fails to stop current

End plate threading wears

Spindle shaft bends -gt Carrier wouldnrsquot be leveled

Striker and arm also bends

8 Introduction to Maintenance Department

Introduction The maintenance department is one of the most important departments of the organization where the organization has its own production Maintenance department of Honda Motorcycle and Scooter India Private Limited (HMSI) is a responsible for all the breakdowns which occur in the machines or where there is any production loss so when to overcome the problem of production loss maintenance team has to work efficiently so that there is no mistake committed by them by which production loss occurs

Some important definitions used by maintenance

Maintenance Action necessary for retaining or restoring an equipment machine or system to the specified operable condition to achieve its maximum useful life It includes planned and preventive maintenance

Planned Maintenance Preventive maintenance carried out according to a fixed plan is called planned maintenance

Preventive Maintenance Systematic inspection detection correction and prevention of incipient failures before they become actual or major failures is called as preventive maintenance

Breakdown Maintenance Repair or replacements performed after a machine has failed to return to its functional state following a malfunction or shutdown is called as breakdown maintenance

Predictive Maintenance Type of preventive maintenance performed continuously or at interval according to the requirement to diagnose and

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 36

monitor a condition or system also called condition based maintenance is called as predictive maintenance

Mean Time To Repair (MTTR) Basic measure of maintainability of repairable items it represents the average mean time required to repair a failed component or device is defined as mean time to repair

Mean Time Between Failures (MTBF) Basic measure of the reliability of repairable items it represents the average number of a life units during which all parts of a device or system perform within their specified limits under specified conditions are called as mean time between failures

Down Time Period during which an equipment or machine is not functional or cannot work It may be due to technical failures mechanical adjustments maintenance or non availability of inputs such as materials labor and power etc is called as down time

Frame Maintenance In this department there are three sections

1 Press Section

2 Weld Section

Engine Maintenance Frame Maintenance

3 Paint Section

PRESS SECTION Press section has mainly four machines

Komatsu Pressndash3

AIDA Press -1

CNC bending machine

Hind Press

These presses are mechanical presses and on this press mudguard fuel tank nose and body cover of the scooters like activa aviator dio shine twister unicorn and twister Process like blanking coining and bending of pipes is done

Blanking is cutting up a large sheer of stock into smaller pieces suitable for next operation

Coining is the process of removal of extra material or to make work piece up to the limit All these mechanical presses are of 500 ton and there only one hydraulic press and this press are used to repair the dyes

CNC pipe bending machines are used to bend the pipes which later used in the manufacturing of the frame

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 38

WELDING SECTION In welding section there are six types of welding machines used in manufacturing of frames and body covers

1 Gantry System Gantry system is a system in which gantry crane is used for transporting the frame and welding is done by the robots and welding is finished by the robots the gantry crane picks up the frame and body covers and puts them on the conveyer or the hanger which goes to the weld body storage On gantry system seam welding is done on the body covers and on the frames with the help of the welding robots This system is fully automatic and there is no involvement of human being it picks up the frame and body covers from the location defined to it then does all the processing on it and then passes it to the conveyer

2 MIG Welding Metal inert gas welding in this inert gas argon is used and argon acts as a shielding gas 1-5 oxygen is used This type of welding uses consumable wire electrode during the welding process that is fed from the wire spool MIG welding has some advantages over the other welding techniques It provides a uniform weld it provides a slag free weld beam and needs little clean up

3 Spot Welding Spot welding is a process in which contacting metal surface are joined by the heat obtained from resistance to electric flow and this type of welding is done on the body covers of the scooter

4 Seam Welding It is a process that welds at a surface of overlapped parts along a length of a joint Weld made by overlapping nuggets this type of welding is done on the fuel tanks and mudguards of scooter

5 Portable Spot Welding It is a portable gun which can be taken to specified range where other spot welding machine faces difficulty in welding This type of the welding is done on body covers of scooters

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 39

6 Fine Boring Fine boring is done on the frame where handle has to fit after fine boring handle is attached to it

When various operation of the welding on the different components of the scooter that is frame mudguard body covers and fuel tank is over then this welded body parts are loaded on to a conveyer hanger which takes these body parts to the weld body storage and in the weld body storage and in weld body storage there are three sections one for model 1 one for model 2 and the last for model 3 When welded body is loaded on to a conveyor then the person who loads these bodies on to the hanger select in which model hanger has to go and the selection is done with a selector switch present Up to 300 hangers can be stored in the storage area that means around 600 frames and 600 body covers can be stored in the weld storage area From storage area hangers move to the unloading area and from unloading area these body covers and frames are loaded on to a Carrier which takes them to the paint section Unloading of the frames and body covers depends on the requirement of the assembly line and which model they are making according to their requirement unloading of model frames and body covers is done Unloading of the model is again done by the selector switch that is when there is requirement of model 1 the person who unloads the frame presses model switch and from storage model 1 moves to the unloading area Similarly when there is requirement of model 2 then operator presses model 2 switch and same goes for the model 3 when the requirement is of model 3 the operator presses the model 3 switch and then from storage model 3 moves to unloading bay

1 Sanding Zone

2 Under Coat

3 Top Coat

Loading In this process frames and body covers are mounted on the carrier of the conveyor line There are two lines for the paint that is paint A line and paint B line both the lines are very much important because in A line loading of frames and front body left right cover and rear body covers are loaded and on B line mudguard and front cowl is loaded and after loading of these parts then the carrier moves to the pretreatment zone

Pre-Treatment In pre-treatment degreasing and dust cleaning is done In pre-treatment bodies have to undergo two operations first wasting with the soft water by this process degreasing is done and all the dust particles are removed from the frames and body covers In general first we get hard water is converted to soft water by ion exchange mechanism

Secondly on bodies and frames phosphate cleaning is done by this method any dust particle or any grease particle left on the frames and body cover is removed

Electro-Deposition In electro deposition carrier which carries frame and body covers turn down into the electro deposition chamber and in electro deposition chamber is filled with the base paint or primer When carrier turns down it strikes high voltage wire and it gets negatively charged and become cathode and paint in the chamber becomes anode then a uniform thin film of base paint is deposited on

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 42

the body covers and frames of the scooter This process is repeated twice and after that it is passed to ED oven

ED Oven In electro deposition oven base coat done on the frame and body covers is heated to 150 degree temperature and this base coat is dried here and after that is passed to paint booth

Paint Booth Paint booth has three sections first one is sanding zone second primary coat or under coat and third is top coat

In sanding zone sanding of the frames and body covers is done and after that it is sent to under coat zone in under coat zone single coat of the paint is done on frames and body covers and in this zone coat of paint is done with the help of robots and after that frames and body covers then sent to top coat zone here in this zone second coat of the paint is done and this second coat of paint is done with the operator and after that these frames and body covers are sent to top coat oven

Top Coat Oven In top coat oven these frames and body covers are heated up to 170 degree temperature and dried and then allowed to cool naturally to room temperature and from there it is sent to the inspection zone

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 43

Inspection Zone In inspection zone body covers and frames have to pass infra-red zone Here IR testing machine checks for irregularities in the paint done and after that these body covers and frames are manually checked by hand for any errors in the paint jobs Parts which pass these tests get the OK mark and move to unloading area

Unloading In this area unloading of frames and body covers takes place Frames and body covers having OK mark are loaded to the paint body store and body covers and frames not having OK mark on them are sent to the repair work station and there they fix the problems which frames and body covers have They are then unloaded and then loaded on to the hanger and the parts go to the paint body storage In storage final or finished body covers and frames are stored which from storage area moves to the final assembly line

To study the various parts of the carrier being used in the paint shop and its problem analysis

Project Introduction

Carrier is defined as a thing which supports or holds up a part during its movement It is used to carry parts to the paint shop where various processes can be performed Carrier forms the basis of the Paint Shop because the movement of the parts from one point to another in the paint shop takes place only due to carrier The parts are loaded on the carrier with the help of a jig and then the motion takes place

Paint shop carrier is the most important moving part in the paint process Most problems and the breakdowns in the paint shop occur due to the carrier only It causes loss to the net production Bends or breaks due to load of body part applied on carrier causes distortions which ultimately results in the breakdown

Carrier is a part of the conveyer system being used in the paint shop The other components of the conveyer system are the prime mover drive (works as the input motion source for chain) chain and chain track carrier carrier turn (for turning the carrier) carrier

revolution (for revolving the carrier) stopper (it temporarily stops the carrier on line) carrier locks auto feeder cylinders and drop lifters which support the motion of carrier

Part Description Of Carrier

Rail

Rail can be of two types ie pre rail and power rail Pre rail is used to drive trolley of the carrier Power rail is used to drive the conveyer system

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 46

Gear Box

Gear Box acts as a Speed Reducer It consists of a worm and worm-wheel arrangement which turns the axis of rotation by 90deg and reduces the speed of the parts The gear box is coupled with the small sprocket Gear transmits power to small sprocket which helps for carrier turn this is also called as reduction gear The relation between the torque and diameter of worm shaft is given by

T (Kg-m) = π16dsup3τ

where τ is the twisting moment

Velocity Ratio = 160

Tensile Strength of Material = 60 Kgmmsup2

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 47

Trolley

There are two trolleys present in a carrier namely Front and the Rear Trolley Front Trolley stops the carrier at a specified position by the actuation of stopper while Rear Trolley stops the next carrier by engaging with the Front trolley of next carrier Trolley Wheel contains ball bearings The outer race serves as a wheel A grease fitting is installed as a greasing port Guide Roller is installed to reduce friction against free rail Pivoting Dog is lifted by the own weight The chain pusher engages to the Pivoting dog for transport To stop the carrier the stopper (installed on the line) pushes down the Pivoting Dog to release the engagement with the pusher

Swivel Pipe

Swivel pipe is used to drive carrier during carrier revolution Swivel pipe is connected to the shaft of worm gear thus it also gets its power from the gear box

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 48

Big Sprocket

It comes in contact with the chain of the carrier turn and is responsible for rotation of the carrier It is mounted on the spindle on which the pan cover is fixed Four carrier dogs are attached to it which control the rotation of the carrier Big sprocket is attached to the spindle shaft plate

Small Sprocket

It is attached to the shaft connected to gear box It comes in contact with the chain of carrier revolution and is responsible for the revolution of the carrier

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 49

Tension Spring

Spring is used to lock turning plate thus stopping carrier revolution It happens when there is no load on the spring But when the load is applied turning plate opens and hence carrier revolution occurs

Insulator Collar

It provides insulation to the carrier in ED process so that there is no current in the frame To avoid the flow of current in the rail of the conveyer system and to avoid damage to the whole system insulator collars are provided

Post

It is mounted on the pan cover and holds the jig by locking it at its position Post mainly has three parts post cover post spacer and post spacer

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 50

Coupling

Bush Coupling transfers the motion from small sprocket shaft to input shaft To avoid overloading at the gear box bush coupling is provided

Guide Pin Arm

It locks the turning of the Big Sprocket by elongating the spring connected to it It has three contact points one is the spring one touches the guide pin of the carrier turn and third is for the engagement and disengagement of big sprocket

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 51

ED Collector

ED collector is used to collect current during ED process and transmits it through the cables to the body parts

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 52

End Striker amp Turn Striker

They are used to control the turning and revolution of the carrier respectively While end striker controls the revolution of the carrier turn striker controls the rotation of the carrier

Problem Analysis Of Carrier

Frame Hole NG

During the motion of the carrier when it is suddenly stopped by the stopper vibrations are produced in it and the pin inserted in the hole of the frame enlarges the size of the hole thereby causing the problem of frame hole NG

To reduce this problem an anti back-up system is applied to reduce the vibrations The NG frame hole is repaired by welding a bush at the site of the hole which is a newly developed Kaizen

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 64

Problems Caused By Loading

Improper loading of the frame body on the carrier damages the insulator collar because an unbalanced force acts upon it and insulator collars being the non-metallic parts are severely affected

R is the resultant vector

This is a production problem which causes the bending of jigs unbalancing of the carrier thereby causing improper motion at the carrier turns and revolutions and also resulting in the body parts falling in the oven

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 65

Gear Box Failure

Gear box of the carrier also fails some time due to overloading or improper coupling

Bending of Striker

Overloading at CTs and CRs causes the bending of the strikers which result in altered motion of the carrier

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 66

Breaking of Post

The post of the carrier can be broken due to variable and unbalanced load acting on the carrier The stresses are developed in the post which leads to its breaking Moreover hammering of the nut for the proper locking can also cause the breaking of nut

Overloading

Overloading is the state when the load on a part of the carrier is higher than its tolerance value Its causes are

If any object interrupts the motion of chain chain is not able to move forward properly causing overloading of chain

Improper position of the jig may lead to unbalancing of the carrier and overload may occur

Guide pin may not properly interact with the arm which may lead to non-alignment

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 67

Chain of the carrier turn may not be in proper position leading to overload at CT

Breaking of any of the carrier dogs will lead to improper revolution of the carrier

Other Problems

Cable breaks -gt Current does not reach to body part

ED COLLECTER burns out -gt It would not collect current

Threading of endndashplate striker wear out -gt Striker would not hit limit switch

Bush between coupling is cut

Bearing sometimes disrupts system

Swivel pipe bends -gt Carrier wouldnrsquot be leveled

Insulator sometimes fails to stop current

End plate threading wears

Spindle shaft bends -gt Carrier wouldnrsquot be leveled

Striker and arm also bends

8 Introduction to Maintenance Department

Introduction The maintenance department is one of the most important departments of the organization where the organization has its own production Maintenance department of Honda Motorcycle and Scooter India Private Limited (HMSI) is a responsible for all the breakdowns which occur in the machines or where there is any production loss so when to overcome the problem of production loss maintenance team has to work efficiently so that there is no mistake committed by them by which production loss occurs

Some important definitions used by maintenance

Maintenance Action necessary for retaining or restoring an equipment machine or system to the specified operable condition to achieve its maximum useful life It includes planned and preventive maintenance

Planned Maintenance Preventive maintenance carried out according to a fixed plan is called planned maintenance

Preventive Maintenance Systematic inspection detection correction and prevention of incipient failures before they become actual or major failures is called as preventive maintenance

Breakdown Maintenance Repair or replacements performed after a machine has failed to return to its functional state following a malfunction or shutdown is called as breakdown maintenance

Predictive Maintenance Type of preventive maintenance performed continuously or at interval according to the requirement to diagnose and

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 36

monitor a condition or system also called condition based maintenance is called as predictive maintenance

Mean Time To Repair (MTTR) Basic measure of maintainability of repairable items it represents the average mean time required to repair a failed component or device is defined as mean time to repair

Mean Time Between Failures (MTBF) Basic measure of the reliability of repairable items it represents the average number of a life units during which all parts of a device or system perform within their specified limits under specified conditions are called as mean time between failures

Down Time Period during which an equipment or machine is not functional or cannot work It may be due to technical failures mechanical adjustments maintenance or non availability of inputs such as materials labor and power etc is called as down time

Frame Maintenance In this department there are three sections

1 Press Section

2 Weld Section

Engine Maintenance Frame Maintenance

3 Paint Section

PRESS SECTION Press section has mainly four machines

Komatsu Pressndash3

AIDA Press -1

CNC bending machine

Hind Press

These presses are mechanical presses and on this press mudguard fuel tank nose and body cover of the scooters like activa aviator dio shine twister unicorn and twister Process like blanking coining and bending of pipes is done

Blanking is cutting up a large sheer of stock into smaller pieces suitable for next operation

Coining is the process of removal of extra material or to make work piece up to the limit All these mechanical presses are of 500 ton and there only one hydraulic press and this press are used to repair the dyes

CNC pipe bending machines are used to bend the pipes which later used in the manufacturing of the frame

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 38

WELDING SECTION In welding section there are six types of welding machines used in manufacturing of frames and body covers

1 Gantry System Gantry system is a system in which gantry crane is used for transporting the frame and welding is done by the robots and welding is finished by the robots the gantry crane picks up the frame and body covers and puts them on the conveyer or the hanger which goes to the weld body storage On gantry system seam welding is done on the body covers and on the frames with the help of the welding robots This system is fully automatic and there is no involvement of human being it picks up the frame and body covers from the location defined to it then does all the processing on it and then passes it to the conveyer

2 MIG Welding Metal inert gas welding in this inert gas argon is used and argon acts as a shielding gas 1-5 oxygen is used This type of welding uses consumable wire electrode during the welding process that is fed from the wire spool MIG welding has some advantages over the other welding techniques It provides a uniform weld it provides a slag free weld beam and needs little clean up

3 Spot Welding Spot welding is a process in which contacting metal surface are joined by the heat obtained from resistance to electric flow and this type of welding is done on the body covers of the scooter

4 Seam Welding It is a process that welds at a surface of overlapped parts along a length of a joint Weld made by overlapping nuggets this type of welding is done on the fuel tanks and mudguards of scooter

5 Portable Spot Welding It is a portable gun which can be taken to specified range where other spot welding machine faces difficulty in welding This type of the welding is done on body covers of scooters

PAINT PROCESS FLOW

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 41

1 Sanding Zone

2 Under Coat

3 Top Coat

Loading In this process frames and body covers are mounted on the carrier of the conveyor line There are two lines for the paint that is paint A line and paint B line both the lines are very much important because in A line loading of frames and front body left right cover and rear body covers are loaded and on B line mudguard and front cowl is loaded and after loading of these parts then the carrier moves to the pretreatment zone

Pre-Treatment In pre-treatment degreasing and dust cleaning is done In pre-treatment bodies have to undergo two operations first wasting with the soft water by this process degreasing is done and all the dust particles are removed from the frames and body covers In general first we get hard water is converted to soft water by ion exchange mechanism

Secondly on bodies and frames phosphate cleaning is done by this method any dust particle or any grease particle left on the frames and body cover is removed

Electro-Deposition In electro deposition carrier which carries frame and body covers turn down into the electro deposition chamber and in electro deposition chamber is filled with the base paint or primer When carrier turns down it strikes high voltage wire and it gets negatively charged and become cathode and paint in the chamber becomes anode then a uniform thin film of base paint is deposited on

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 42

the body covers and frames of the scooter This process is repeated twice and after that it is passed to ED oven

ED Oven In electro deposition oven base coat done on the frame and body covers is heated to 150 degree temperature and this base coat is dried here and after that is passed to paint booth

Paint Booth Paint booth has three sections first one is sanding zone second primary coat or under coat and third is top coat

In sanding zone sanding of the frames and body covers is done and after that it is sent to under coat zone in under coat zone single coat of the paint is done on frames and body covers and in this zone coat of paint is done with the help of robots and after that frames and body covers then sent to top coat zone here in this zone second coat of the paint is done and this second coat of paint is done with the operator and after that these frames and body covers are sent to top coat oven

Top Coat Oven In top coat oven these frames and body covers are heated up to 170 degree temperature and dried and then allowed to cool naturally to room temperature and from there it is sent to the inspection zone

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 43

Inspection Zone In inspection zone body covers and frames have to pass infra-red zone Here IR testing machine checks for irregularities in the paint done and after that these body covers and frames are manually checked by hand for any errors in the paint jobs Parts which pass these tests get the OK mark and move to unloading area

Unloading In this area unloading of frames and body covers takes place Frames and body covers having OK mark are loaded to the paint body store and body covers and frames not having OK mark on them are sent to the repair work station and there they fix the problems which frames and body covers have They are then unloaded and then loaded on to the hanger and the parts go to the paint body storage In storage final or finished body covers and frames are stored which from storage area moves to the final assembly line

9 ProjectProject Definition

To study the various parts of the carrier being used in the paint shop and its problem analysis

Project Introduction

Carrier is defined as a thing which supports or holds up a part during its movement It is used to carry parts to the paint shop where various processes can be performed Carrier forms the basis of the Paint Shop because the movement of the parts from one point to another in the paint shop takes place only due to carrier The parts are loaded on the carrier with the help of a jig and then the motion takes place

Paint shop carrier is the most important moving part in the paint process Most problems and the breakdowns in the paint shop occur due to the carrier only It causes loss to the net production Bends or breaks due to load of body part applied on carrier causes distortions which ultimately results in the breakdown

Carrier is a part of the conveyer system being used in the paint shop The other components of the conveyer system are the prime mover drive (works as the input motion source for chain) chain and chain track carrier carrier turn (for turning the carrier) carrier

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 45

revolution (for revolving the carrier) stopper (it temporarily stops the carrier on line) carrier locks auto feeder cylinders and drop lifters which support the motion of carrier

Part Description Of Carrier

Rail

Rail can be of two types ie pre rail and power rail Pre rail is used to drive trolley of the carrier Power rail is used to drive the conveyer system

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 46

Gear Box

Gear Box acts as a Speed Reducer It consists of a worm and worm-wheel arrangement which turns the axis of rotation by 90deg and reduces the speed of the parts The gear box is coupled with the small sprocket Gear transmits power to small sprocket which helps for carrier turn this is also called as reduction gear The relation between the torque and diameter of worm shaft is given by

T (Kg-m) = π16dsup3τ

where τ is the twisting moment

Velocity Ratio = 160

Tensile Strength of Material = 60 Kgmmsup2

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 47

Trolley

There are two trolleys present in a carrier namely Front and the Rear Trolley Front Trolley stops the carrier at a specified position by the actuation of stopper while Rear Trolley stops the next carrier by engaging with the Front trolley of next carrier Trolley Wheel contains ball bearings The outer race serves as a wheel A grease fitting is installed as a greasing port Guide Roller is installed to reduce friction against free rail Pivoting Dog is lifted by the own weight The chain pusher engages to the Pivoting dog for transport To stop the carrier the stopper (installed on the line) pushes down the Pivoting Dog to release the engagement with the pusher

Swivel Pipe

Swivel pipe is used to drive carrier during carrier revolution Swivel pipe is connected to the shaft of worm gear thus it also gets its power from the gear box

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 48

Big Sprocket

It comes in contact with the chain of the carrier turn and is responsible for rotation of the carrier It is mounted on the spindle on which the pan cover is fixed Four carrier dogs are attached to it which control the rotation of the carrier Big sprocket is attached to the spindle shaft plate

Small Sprocket

It is attached to the shaft connected to gear box It comes in contact with the chain of carrier revolution and is responsible for the revolution of the carrier

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 49

Tension Spring

Spring is used to lock turning plate thus stopping carrier revolution It happens when there is no load on the spring But when the load is applied turning plate opens and hence carrier revolution occurs

Insulator Collar

It provides insulation to the carrier in ED process so that there is no current in the frame To avoid the flow of current in the rail of the conveyer system and to avoid damage to the whole system insulator collars are provided

Post

It is mounted on the pan cover and holds the jig by locking it at its position Post mainly has three parts post cover post spacer and post spacer

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 50

Coupling

Problem Analysis Of Carrier

Frame Hole NG

During the motion of the carrier when it is suddenly stopped by the stopper vibrations are produced in it and the pin inserted in the hole of the frame enlarges the size of the hole thereby causing the problem of frame hole NG

To reduce this problem an anti back-up system is applied to reduce the vibrations The NG frame hole is repaired by welding a bush at the site of the hole which is a newly developed Kaizen

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 64

Problems Caused By Loading

Improper loading of the frame body on the carrier damages the insulator collar because an unbalanced force acts upon it and insulator collars being the non-metallic parts are severely affected

R is the resultant vector

This is a production problem which causes the bending of jigs unbalancing of the carrier thereby causing improper motion at the carrier turns and revolutions and also resulting in the body parts falling in the oven

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 65

Gear Box Failure

Gear box of the carrier also fails some time due to overloading or improper coupling

Bending of Striker

Overloading at CTs and CRs causes the bending of the strikers which result in altered motion of the carrier

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 66

Breaking of Post

The post of the carrier can be broken due to variable and unbalanced load acting on the carrier The stresses are developed in the post which leads to its breaking Moreover hammering of the nut for the proper locking can also cause the breaking of nut

Overloading

Overloading is the state when the load on a part of the carrier is higher than its tolerance value Its causes are

If any object interrupts the motion of chain chain is not able to move forward properly causing overloading of chain

Improper position of the jig may lead to unbalancing of the carrier and overload may occur

Guide pin may not properly interact with the arm which may lead to non-alignment

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 67

Chain of the carrier turn may not be in proper position leading to overload at CT

Breaking of any of the carrier dogs will lead to improper revolution of the carrier

Other Problems

Cable breaks -gt Current does not reach to body part

ED COLLECTER burns out -gt It would not collect current

Threading of endndashplate striker wear out -gt Striker would not hit limit switch

Bush between coupling is cut

Bearing sometimes disrupts system

Swivel pipe bends -gt Carrier wouldnrsquot be leveled

Insulator sometimes fails to stop current

End plate threading wears

Spindle shaft bends -gt Carrier wouldnrsquot be leveled

Striker and arm also bends

PRESS SECTION Press section has mainly four machines

Komatsu Pressndash3

AIDA Press -1

CNC bending machine

Hind Press

These presses are mechanical presses and on this press mudguard fuel tank nose and body cover of the scooters like activa aviator dio shine twister unicorn and twister Process like blanking coining and bending of pipes is done

Blanking is cutting up a large sheer of stock into smaller pieces suitable for next operation

Coining is the process of removal of extra material or to make work piece up to the limit All these mechanical presses are of 500 ton and there only one hydraulic press and this press are used to repair the dyes

CNC pipe bending machines are used to bend the pipes which later used in the manufacturing of the frame

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 38

WELDING SECTION In welding section there are six types of welding machines used in manufacturing of frames and body covers

1 Gantry System Gantry system is a system in which gantry crane is used for transporting the frame and welding is done by the robots and welding is finished by the robots the gantry crane picks up the frame and body covers and puts them on the conveyer or the hanger which goes to the weld body storage On gantry system seam welding is done on the body covers and on the frames with the help of the welding robots This system is fully automatic and there is no involvement of human being it picks up the frame and body covers from the location defined to it then does all the processing on it and then passes it to the conveyer

2 MIG Welding Metal inert gas welding in this inert gas argon is used and argon acts as a shielding gas 1-5 oxygen is used This type of welding uses consumable wire electrode during the welding process that is fed from the wire spool MIG welding has some advantages over the other welding techniques It provides a uniform weld it provides a slag free weld beam and needs little clean up

3 Spot Welding Spot welding is a process in which contacting metal surface are joined by the heat obtained from resistance to electric flow and this type of welding is done on the body covers of the scooter

4 Seam Welding It is a process that welds at a surface of overlapped parts along a length of a joint Weld made by overlapping nuggets this type of welding is done on the fuel tanks and mudguards of scooter

5 Portable Spot Welding It is a portable gun which can be taken to specified range where other spot welding machine faces difficulty in welding This type of the welding is done on body covers of scooters

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 39

6 Fine Boring Fine boring is done on the frame where handle has to fit after fine boring handle is attached to it

When various operation of the welding on the different components of the scooter that is frame mudguard body covers and fuel tank is over then this welded body parts are loaded on to a conveyer hanger which takes these body parts to the weld body storage and in the weld body storage and in weld body storage there are three sections one for model 1 one for model 2 and the last for model 3 When welded body is loaded on to a conveyor then the person who loads these bodies on to the hanger select in which model hanger has to go and the selection is done with a selector switch present Up to 300 hangers can be stored in the storage area that means around 600 frames and 600 body covers can be stored in the weld storage area From storage area hangers move to the unloading area and from unloading area these body covers and frames are loaded on to a Carrier which takes them to the paint section Unloading of the frames and body covers depends on the requirement of the assembly line and which model they are making according to their requirement unloading of model frames and body covers is done Unloading of the model is again done by the selector switch that is when there is requirement of model 1 the person who unloads the frame presses model switch and from storage model 1 moves to the unloading area Similarly when there is requirement of model 2 then operator presses model 2 switch and same goes for the model 3 when the requirement is of model 3 the operator presses the model 3 switch and then from storage model 3 moves to unloading bay

Top Coat Oven

Inspection Zone

Unloading

PAINT PROCESS FLOW

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 41

1 Sanding Zone

2 Under Coat

3 Top Coat

Loading In this process frames and body covers are mounted on the carrier of the conveyor line There are two lines for the paint that is paint A line and paint B line both the lines are very much important because in A line loading of frames and front body left right cover and rear body covers are loaded and on B line mudguard and front cowl is loaded and after loading of these parts then the carrier moves to the pretreatment zone

Pre-Treatment In pre-treatment degreasing and dust cleaning is done In pre-treatment bodies have to undergo two operations first wasting with the soft water by this process degreasing is done and all the dust particles are removed from the frames and body covers In general first we get hard water is converted to soft water by ion exchange mechanism

Secondly on bodies and frames phosphate cleaning is done by this method any dust particle or any grease particle left on the frames and body cover is removed

Electro-Deposition In electro deposition carrier which carries frame and body covers turn down into the electro deposition chamber and in electro deposition chamber is filled with the base paint or primer When carrier turns down it strikes high voltage wire and it gets negatively charged and become cathode and paint in the chamber becomes anode then a uniform thin film of base paint is deposited on

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 42

the body covers and frames of the scooter This process is repeated twice and after that it is passed to ED oven

ED Oven In electro deposition oven base coat done on the frame and body covers is heated to 150 degree temperature and this base coat is dried here and after that is passed to paint booth

Paint Booth Paint booth has three sections first one is sanding zone second primary coat or under coat and third is top coat

In sanding zone sanding of the frames and body covers is done and after that it is sent to under coat zone in under coat zone single coat of the paint is done on frames and body covers and in this zone coat of paint is done with the help of robots and after that frames and body covers then sent to top coat zone here in this zone second coat of the paint is done and this second coat of paint is done with the operator and after that these frames and body covers are sent to top coat oven

Top Coat Oven In top coat oven these frames and body covers are heated up to 170 degree temperature and dried and then allowed to cool naturally to room temperature and from there it is sent to the inspection zone

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 43

Inspection Zone In inspection zone body covers and frames have to pass infra-red zone Here IR testing machine checks for irregularities in the paint done and after that these body covers and frames are manually checked by hand for any errors in the paint jobs Parts which pass these tests get the OK mark and move to unloading area

Unloading In this area unloading of frames and body covers takes place Frames and body covers having OK mark are loaded to the paint body store and body covers and frames not having OK mark on them are sent to the repair work station and there they fix the problems which frames and body covers have They are then unloaded and then loaded on to the hanger and the parts go to the paint body storage In storage final or finished body covers and frames are stored which from storage area moves to the final assembly line

9 ProjectProject Definition

To study the various parts of the carrier being used in the paint shop and its problem analysis

Project Introduction

Carrier is defined as a thing which supports or holds up a part during its movement It is used to carry parts to the paint shop where various processes can be performed Carrier forms the basis of the Paint Shop because the movement of the parts from one point to another in the paint shop takes place only due to carrier The parts are loaded on the carrier with the help of a jig and then the motion takes place

Paint shop carrier is the most important moving part in the paint process Most problems and the breakdowns in the paint shop occur due to the carrier only It causes loss to the net production Bends or breaks due to load of body part applied on carrier causes distortions which ultimately results in the breakdown

Carrier is a part of the conveyer system being used in the paint shop The other components of the conveyer system are the prime mover drive (works as the input motion source for chain) chain and chain track carrier carrier turn (for turning the carrier) carrier

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 45

revolution (for revolving the carrier) stopper (it temporarily stops the carrier on line) carrier locks auto feeder cylinders and drop lifters which support the motion of carrier

Part Description Of Carrier

Rail

Rail can be of two types ie pre rail and power rail Pre rail is used to drive trolley of the carrier Power rail is used to drive the conveyer system

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 46

Gear Box

Gear Box acts as a Speed Reducer It consists of a worm and worm-wheel arrangement which turns the axis of rotation by 90deg and reduces the speed of the parts The gear box is coupled with the small sprocket Gear transmits power to small sprocket which helps for carrier turn this is also called as reduction gear The relation between the torque and diameter of worm shaft is given by

T (Kg-m) = π16dsup3τ

where τ is the twisting moment

Velocity Ratio = 160

Tensile Strength of Material = 60 Kgmmsup2

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 47

Trolley

Problem Analysis Of Carrier

Frame Hole NG

During the motion of the carrier when it is suddenly stopped by the stopper vibrations are produced in it and the pin inserted in the hole of the frame enlarges the size of the hole thereby causing the problem of frame hole NG

To reduce this problem an anti back-up system is applied to reduce the vibrations The NG frame hole is repaired by welding a bush at the site of the hole which is a newly developed Kaizen

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 64

Problems Caused By Loading

Improper loading of the frame body on the carrier damages the insulator collar because an unbalanced force acts upon it and insulator collars being the non-metallic parts are severely affected

R is the resultant vector

This is a production problem which causes the bending of jigs unbalancing of the carrier thereby causing improper motion at the carrier turns and revolutions and also resulting in the body parts falling in the oven

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 65

Gear Box Failure

Gear box of the carrier also fails some time due to overloading or improper coupling

Bending of Striker

Overloading at CTs and CRs causes the bending of the strikers which result in altered motion of the carrier

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 66

Breaking of Post

The post of the carrier can be broken due to variable and unbalanced load acting on the carrier The stresses are developed in the post which leads to its breaking Moreover hammering of the nut for the proper locking can also cause the breaking of nut

Overloading

Overloading is the state when the load on a part of the carrier is higher than its tolerance value Its causes are

If any object interrupts the motion of chain chain is not able to move forward properly causing overloading of chain

Improper position of the jig may lead to unbalancing of the carrier and overload may occur

Guide pin may not properly interact with the arm which may lead to non-alignment

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 67

Chain of the carrier turn may not be in proper position leading to overload at CT

Breaking of any of the carrier dogs will lead to improper revolution of the carrier

Other Problems

Cable breaks -gt Current does not reach to body part

ED COLLECTER burns out -gt It would not collect current

Threading of endndashplate striker wear out -gt Striker would not hit limit switch

Bush between coupling is cut

Bearing sometimes disrupts system

Swivel pipe bends -gt Carrier wouldnrsquot be leveled

Insulator sometimes fails to stop current

End plate threading wears

Spindle shaft bends -gt Carrier wouldnrsquot be leveled

Striker and arm also bends

8 Introduction to Maintenance Department

Introduction The maintenance department is one of the most important departments of the organization where the organization has its own production Maintenance department of Honda Motorcycle and Scooter India Private Limited (HMSI) is a responsible for all the breakdowns which occur in the machines or where there is any production loss so when to overcome the problem of production loss maintenance team has to work efficiently so that there is no mistake committed by them by which production loss occurs

Some important definitions used by maintenance

Maintenance Action necessary for retaining or restoring an equipment machine or system to the specified operable condition to achieve its maximum useful life It includes planned and preventive maintenance

Planned Maintenance Preventive maintenance carried out according to a fixed plan is called planned maintenance

Preventive Maintenance Systematic inspection detection correction and prevention of incipient failures before they become actual or major failures is called as preventive maintenance

Breakdown Maintenance Repair or replacements performed after a machine has failed to return to its functional state following a malfunction or shutdown is called as breakdown maintenance

Predictive Maintenance Type of preventive maintenance performed continuously or at interval according to the requirement to diagnose and

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 36

monitor a condition or system also called condition based maintenance is called as predictive maintenance

Mean Time To Repair (MTTR) Basic measure of maintainability of repairable items it represents the average mean time required to repair a failed component or device is defined as mean time to repair

Mean Time Between Failures (MTBF) Basic measure of the reliability of repairable items it represents the average number of a life units during which all parts of a device or system perform within their specified limits under specified conditions are called as mean time between failures

Down Time Period during which an equipment or machine is not functional or cannot work It may be due to technical failures mechanical adjustments maintenance or non availability of inputs such as materials labor and power etc is called as down time

Frame Maintenance In this department there are three sections

1 Press Section

2 Weld Section

3 Paint Section

PRESS SECTION Press section has mainly four machines

Komatsu Pressndash3

AIDA Press -1

CNC bending machine

Hind Press

These presses are mechanical presses and on this press mudguard fuel tank nose and body cover of the scooters like activa aviator dio shine twister unicorn and twister Process like blanking coining and bending of pipes is done

Blanking is cutting up a large sheer of stock into smaller pieces suitable for next operation

Coining is the process of removal of extra material or to make work piece up to the limit All these mechanical presses are of 500 ton and there only one hydraulic press and this press are used to repair the dyes

CNC pipe bending machines are used to bend the pipes which later used in the manufacturing of the frame

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 38

WELDING SECTION In welding section there are six types of welding machines used in manufacturing of frames and body covers

1 Gantry System Gantry system is a system in which gantry crane is used for transporting the frame and welding is done by the robots and welding is finished by the robots the gantry crane picks up the frame and body covers and puts them on the conveyer or the hanger which goes to the weld body storage On gantry system seam welding is done on the body covers and on the frames with the help of the welding robots This system is fully automatic and there is no involvement of human being it picks up the frame and body covers from the location defined to it then does all the processing on it and then passes it to the conveyer

2 MIG Welding Metal inert gas welding in this inert gas argon is used and argon acts as a shielding gas 1-5 oxygen is used This type of welding uses consumable wire electrode during the welding process that is fed from the wire spool MIG welding has some advantages over the other welding techniques It provides a uniform weld it provides a slag free weld beam and needs little clean up

3 Spot Welding Spot welding is a process in which contacting metal surface are joined by the heat obtained from resistance to electric flow and this type of welding is done on the body covers of the scooter

4 Seam Welding It is a process that welds at a surface of overlapped parts along a length of a joint Weld made by overlapping nuggets this type of welding is done on the fuel tanks and mudguards of scooter

5 Portable Spot Welding It is a portable gun which can be taken to specified range where other spot welding machine faces difficulty in welding This type of the welding is done on body covers of scooters

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 39

6 Fine Boring Fine boring is done on the frame where handle has to fit after fine boring handle is attached to it

When various operation of the welding on the different components of the scooter that is frame mudguard body covers and fuel tank is over then this welded body parts are loaded on to a conveyer hanger which takes these body parts to the weld body storage and in the weld body storage and in weld body storage there are three sections one for model 1 one for model 2 and the last for model 3 When welded body is loaded on to a conveyor then the person who loads these bodies on to the hanger select in which model hanger has to go and the selection is done with a selector switch present Up to 300 hangers can be stored in the storage area that means around 600 frames and 600 body covers can be stored in the weld storage area From storage area hangers move to the unloading area and from unloading area these body covers and frames are loaded on to a Carrier which takes them to the paint section Unloading of the frames and body covers depends on the requirement of the assembly line and which model they are making according to their requirement unloading of model frames and body covers is done Unloading of the model is again done by the selector switch that is when there is requirement of model 1 the person who unloads the frame presses model switch and from storage model 1 moves to the unloading area Similarly when there is requirement of model 2 then operator presses model 2 switch and same goes for the model 3 when the requirement is of model 3 the operator presses the model 3 switch and then from storage model 3 moves to unloading bay

Top Coat Oven

Inspection Zone

Unloading

PAINT PROCESS FLOW

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 41

1 Sanding Zone

2 Under Coat

3 Top Coat

Loading In this process frames and body covers are mounted on the carrier of the conveyor line There are two lines for the paint that is paint A line and paint B line both the lines are very much important because in A line loading of frames and front body left right cover and rear body covers are loaded and on B line mudguard and front cowl is loaded and after loading of these parts then the carrier moves to the pretreatment zone

Pre-Treatment In pre-treatment degreasing and dust cleaning is done In pre-treatment bodies have to undergo two operations first wasting with the soft water by this process degreasing is done and all the dust particles are removed from the frames and body covers In general first we get hard water is converted to soft water by ion exchange mechanism

Secondly on bodies and frames phosphate cleaning is done by this method any dust particle or any grease particle left on the frames and body cover is removed

Electro-Deposition In electro deposition carrier which carries frame and body covers turn down into the electro deposition chamber and in electro deposition chamber is filled with the base paint or primer When carrier turns down it strikes high voltage wire and it gets negatively charged and become cathode and paint in the chamber becomes anode then a uniform thin film of base paint is deposited on

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 42

the body covers and frames of the scooter This process is repeated twice and after that it is passed to ED oven

ED Oven In electro deposition oven base coat done on the frame and body covers is heated to 150 degree temperature and this base coat is dried here and after that is passed to paint booth

Paint Booth Paint booth has three sections first one is sanding zone second primary coat or under coat and third is top coat

In sanding zone sanding of the frames and body covers is done and after that it is sent to under coat zone in under coat zone single coat of the paint is done on frames and body covers and in this zone coat of paint is done with the help of robots and after that frames and body covers then sent to top coat zone here in this zone second coat of the paint is done and this second coat of paint is done with the operator and after that these frames and body covers are sent to top coat oven

Top Coat Oven In top coat oven these frames and body covers are heated up to 170 degree temperature and dried and then allowed to cool naturally to room temperature and from there it is sent to the inspection zone

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 43

Inspection Zone In inspection zone body covers and frames have to pass infra-red zone Here IR testing machine checks for irregularities in the paint done and after that these body covers and frames are manually checked by hand for any errors in the paint jobs Parts which pass these tests get the OK mark and move to unloading area

Unloading In this area unloading of frames and body covers takes place Frames and body covers having OK mark are loaded to the paint body store and body covers and frames not having OK mark on them are sent to the repair work station and there they fix the problems which frames and body covers have They are then unloaded and then loaded on to the hanger and the parts go to the paint body storage In storage final or finished body covers and frames are stored which from storage area moves to the final assembly line

9 ProjectProject Definition

To study the various parts of the carrier being used in the paint shop and its problem analysis

Project Introduction

Carrier is defined as a thing which supports or holds up a part during its movement It is used to carry parts to the paint shop where various processes can be performed Carrier forms the basis of the Paint Shop because the movement of the parts from one point to another in the paint shop takes place only due to carrier The parts are loaded on the carrier with the help of a jig and then the motion takes place

Paint shop carrier is the most important moving part in the paint process Most problems and the breakdowns in the paint shop occur due to the carrier only It causes loss to the net production Bends or breaks due to load of body part applied on carrier causes distortions which ultimately results in the breakdown

Carrier is a part of the conveyer system being used in the paint shop The other components of the conveyer system are the prime mover drive (works as the input motion source for chain) chain and chain track carrier carrier turn (for turning the carrier) carrier

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 45

revolution (for revolving the carrier) stopper (it temporarily stops the carrier on line) carrier locks auto feeder cylinders and drop lifters which support the motion of carrier

Part Description Of Carrier

Rail

Rail can be of two types ie pre rail and power rail Pre rail is used to drive trolley of the carrier Power rail is used to drive the conveyer system

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 46

Gear Box

Gear Box acts as a Speed Reducer It consists of a worm and worm-wheel arrangement which turns the axis of rotation by 90deg and reduces the speed of the parts The gear box is coupled with the small sprocket Gear transmits power to small sprocket which helps for carrier turn this is also called as reduction gear The relation between the torque and diameter of worm shaft is given by

T (Kg-m) = π16dsup3τ

where τ is the twisting moment

Problem Analysis Of Carrier

Frame Hole NG

During the motion of the carrier when it is suddenly stopped by the stopper vibrations are produced in it and the pin inserted in the hole of the frame enlarges the size of the hole thereby causing the problem of frame hole NG

To reduce this problem an anti back-up system is applied to reduce the vibrations The NG frame hole is repaired by welding a bush at the site of the hole which is a newly developed Kaizen

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 64

Problems Caused By Loading

Improper loading of the frame body on the carrier damages the insulator collar because an unbalanced force acts upon it and insulator collars being the non-metallic parts are severely affected

R is the resultant vector

This is a production problem which causes the bending of jigs unbalancing of the carrier thereby causing improper motion at the carrier turns and revolutions and also resulting in the body parts falling in the oven

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 65

Gear Box Failure

Gear box of the carrier also fails some time due to overloading or improper coupling

Bending of Striker

Overloading at CTs and CRs causes the bending of the strikers which result in altered motion of the carrier

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 66

Breaking of Post

The post of the carrier can be broken due to variable and unbalanced load acting on the carrier The stresses are developed in the post which leads to its breaking Moreover hammering of the nut for the proper locking can also cause the breaking of nut

Overloading

Overloading is the state when the load on a part of the carrier is higher than its tolerance value Its causes are

If any object interrupts the motion of chain chain is not able to move forward properly causing overloading of chain

Improper position of the jig may lead to unbalancing of the carrier and overload may occur

Guide pin may not properly interact with the arm which may lead to non-alignment

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 67

Chain of the carrier turn may not be in proper position leading to overload at CT

Breaking of any of the carrier dogs will lead to improper revolution of the carrier

Other Problems

Cable breaks -gt Current does not reach to body part

ED COLLECTER burns out -gt It would not collect current

Threading of endndashplate striker wear out -gt Striker would not hit limit switch

Bush between coupling is cut

Bearing sometimes disrupts system

Swivel pipe bends -gt Carrier wouldnrsquot be leveled

Insulator sometimes fails to stop current

End plate threading wears

Spindle shaft bends -gt Carrier wouldnrsquot be leveled

Striker and arm also bends

8 Introduction to Maintenance Department

Introduction The maintenance department is one of the most important departments of the organization where the organization has its own production Maintenance department of Honda Motorcycle and Scooter India Private Limited (HMSI) is a responsible for all the breakdowns which occur in the machines or where there is any production loss so when to overcome the problem of production loss maintenance team has to work efficiently so that there is no mistake committed by them by which production loss occurs

Some important definitions used by maintenance

Maintenance Action necessary for retaining or restoring an equipment machine or system to the specified operable condition to achieve its maximum useful life It includes planned and preventive maintenance

Planned Maintenance Preventive maintenance carried out according to a fixed plan is called planned maintenance

Preventive Maintenance Systematic inspection detection correction and prevention of incipient failures before they become actual or major failures is called as preventive maintenance

Breakdown Maintenance Repair or replacements performed after a machine has failed to return to its functional state following a malfunction or shutdown is called as breakdown maintenance

Predictive Maintenance Type of preventive maintenance performed continuously or at interval according to the requirement to diagnose and

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 36

monitor a condition or system also called condition based maintenance is called as predictive maintenance

Mean Time To Repair (MTTR) Basic measure of maintainability of repairable items it represents the average mean time required to repair a failed component or device is defined as mean time to repair

Mean Time Between Failures (MTBF) Basic measure of the reliability of repairable items it represents the average number of a life units during which all parts of a device or system perform within their specified limits under specified conditions are called as mean time between failures

Down Time Period during which an equipment or machine is not functional or cannot work It may be due to technical failures mechanical adjustments maintenance or non availability of inputs such as materials labor and power etc is called as down time

Frame Maintenance In this department there are three sections

1 Press Section

2 Weld Section

Engine Maintenance Frame Maintenance

3 Paint Section

PRESS SECTION Press section has mainly four machines

Komatsu Pressndash3

AIDA Press -1

CNC bending machine

Hind Press

These presses are mechanical presses and on this press mudguard fuel tank nose and body cover of the scooters like activa aviator dio shine twister unicorn and twister Process like blanking coining and bending of pipes is done

Blanking is cutting up a large sheer of stock into smaller pieces suitable for next operation

Coining is the process of removal of extra material or to make work piece up to the limit All these mechanical presses are of 500 ton and there only one hydraulic press and this press are used to repair the dyes

CNC pipe bending machines are used to bend the pipes which later used in the manufacturing of the frame

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 38

WELDING SECTION In welding section there are six types of welding machines used in manufacturing of frames and body covers

1 Gantry System Gantry system is a system in which gantry crane is used for transporting the frame and welding is done by the robots and welding is finished by the robots the gantry crane picks up the frame and body covers and puts them on the conveyer or the hanger which goes to the weld body storage On gantry system seam welding is done on the body covers and on the frames with the help of the welding robots This system is fully automatic and there is no involvement of human being it picks up the frame and body covers from the location defined to it then does all the processing on it and then passes it to the conveyer

2 MIG Welding Metal inert gas welding in this inert gas argon is used and argon acts as a shielding gas 1-5 oxygen is used This type of welding uses consumable wire electrode during the welding process that is fed from the wire spool MIG welding has some advantages over the other welding techniques It provides a uniform weld it provides a slag free weld beam and needs little clean up

3 Spot Welding Spot welding is a process in which contacting metal surface are joined by the heat obtained from resistance to electric flow and this type of welding is done on the body covers of the scooter

4 Seam Welding It is a process that welds at a surface of overlapped parts along a length of a joint Weld made by overlapping nuggets this type of welding is done on the fuel tanks and mudguards of scooter

5 Portable Spot Welding It is a portable gun which can be taken to specified range where other spot welding machine faces difficulty in welding This type of the welding is done on body covers of scooters

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 39

6 Fine Boring Fine boring is done on the frame where handle has to fit after fine boring handle is attached to it

When various operation of the welding on the different components of the scooter that is frame mudguard body covers and fuel tank is over then this welded body parts are loaded on to a conveyer hanger which takes these body parts to the weld body storage and in the weld body storage and in weld body storage there are three sections one for model 1 one for model 2 and the last for model 3 When welded body is loaded on to a conveyor then the person who loads these bodies on to the hanger select in which model hanger has to go and the selection is done with a selector switch present Up to 300 hangers can be stored in the storage area that means around 600 frames and 600 body covers can be stored in the weld storage area From storage area hangers move to the unloading area and from unloading area these body covers and frames are loaded on to a Carrier which takes them to the paint section Unloading of the frames and body covers depends on the requirement of the assembly line and which model they are making according to their requirement unloading of model frames and body covers is done Unloading of the model is again done by the selector switch that is when there is requirement of model 1 the person who unloads the frame presses model switch and from storage model 1 moves to the unloading area Similarly when there is requirement of model 2 then operator presses model 2 switch and same goes for the model 3 when the requirement is of model 3 the operator presses the model 3 switch and then from storage model 3 moves to unloading bay

PAINT SECTION Paint section is very important section In this section different treatments are done on the body covers and frames and it is a step by step process done as follows

Loading

Pre-Treatment

Electro-Deposition

ED Oven

Booth

Top Coat Oven

Inspection Zone

Unloading

PAINT PROCESS FLOW

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 41

1 Sanding Zone

2 Under Coat

3 Top Coat

Loading In this process frames and body covers are mounted on the carrier of the conveyor line There are two lines for the paint that is paint A line and paint B line both the lines are very much important because in A line loading of frames and front body left right cover and rear body covers are loaded and on B line mudguard and front cowl is loaded and after loading of these parts then the carrier moves to the pretreatment zone

Pre-Treatment In pre-treatment degreasing and dust cleaning is done In pre-treatment bodies have to undergo two operations first wasting with the soft water by this process degreasing is done and all the dust particles are removed from the frames and body covers In general first we get hard water is converted to soft water by ion exchange mechanism

Secondly on bodies and frames phosphate cleaning is done by this method any dust particle or any grease particle left on the frames and body cover is removed

Electro-Deposition In electro deposition carrier which carries frame and body covers turn down into the electro deposition chamber and in electro deposition chamber is filled with the base paint or primer When carrier turns down it strikes high voltage wire and it gets negatively charged and become cathode and paint in the chamber becomes anode then a uniform thin film of base paint is deposited on

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 42

the body covers and frames of the scooter This process is repeated twice and after that it is passed to ED oven

ED Oven In electro deposition oven base coat done on the frame and body covers is heated to 150 degree temperature and this base coat is dried here and after that is passed to paint booth

Paint Booth Paint booth has three sections first one is sanding zone second primary coat or under coat and third is top coat

In sanding zone sanding of the frames and body covers is done and after that it is sent to under coat zone in under coat zone single coat of the paint is done on frames and body covers and in this zone coat of paint is done with the help of robots and after that frames and body covers then sent to top coat zone here in this zone second coat of the paint is done and this second coat of paint is done with the operator and after that these frames and body covers are sent to top coat oven

Top Coat Oven In top coat oven these frames and body covers are heated up to 170 degree temperature and dried and then allowed to cool naturally to room temperature and from there it is sent to the inspection zone

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 43

Inspection Zone In inspection zone body covers and frames have to pass infra-red zone Here IR testing machine checks for irregularities in the paint done and after that these body covers and frames are manually checked by hand for any errors in the paint jobs Parts which pass these tests get the OK mark and move to unloading area

Unloading In this area unloading of frames and body covers takes place Frames and body covers having OK mark are loaded to the paint body store and body covers and frames not having OK mark on them are sent to the repair work station and there they fix the problems which frames and body covers have They are then unloaded and then loaded on to the hanger and the parts go to the paint body storage In storage final or finished body covers and frames are stored which from storage area moves to the final assembly line

9 ProjectProject Definition

To study the various parts of the carrier being used in the paint shop and its problem analysis

Project Introduction

Carrier is defined as a thing which supports or holds up a part during its movement It is used to carry parts to the paint shop where various processes can be performed Carrier forms the basis of the Paint Shop because the movement of the parts from one point to another in the paint shop takes place only due to carrier The parts are loaded on the carrier with the help of a jig and then the motion takes place

Paint shop carrier is the most important moving part in the paint process Most problems and the breakdowns in the paint shop occur due to the carrier only It causes loss to the net production Bends or breaks due to load of body part applied on carrier causes distortions which ultimately results in the breakdown

Carrier is a part of the conveyer system being used in the paint shop The other components of the conveyer system are the prime mover drive (works as the input motion source for chain) chain and chain track carrier carrier turn (for turning the carrier) carrier

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 45

revolution (for revolving the carrier) stopper (it temporarily stops the carrier on line) carrier locks auto feeder cylinders and drop lifters which support the motion of carrier

Part Description Of Carrier

Rail

Rail can be of two types ie pre rail and power rail Pre rail is used to drive trolley of the carrier Power rail is used to drive the conveyer system

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 46

Gear Box

Gear Box acts as a Speed Reducer It consists of a worm and worm-wheel arrangement which turns the axis of rotation by 90deg and reduces the speed of the parts The gear box is coupled with the small sprocket Gear transmits power to small sprocket which helps for carrier turn this is also called as reduction gear The relation between the torque and diameter of worm shaft is given by

T (Kg-m) = π16dsup3τ

where τ is the twisting moment

Velocity Ratio = 160

Tensile Strength of Material = 60 Kgmmsup2

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 47

Trolley

Problem Analysis Of Carrier

Frame Hole NG

During the motion of the carrier when it is suddenly stopped by the stopper vibrations are produced in it and the pin inserted in the hole of the frame enlarges the size of the hole thereby causing the problem of frame hole NG

To reduce this problem an anti back-up system is applied to reduce the vibrations The NG frame hole is repaired by welding a bush at the site of the hole which is a newly developed Kaizen

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 64

Problems Caused By Loading

Improper loading of the frame body on the carrier damages the insulator collar because an unbalanced force acts upon it and insulator collars being the non-metallic parts are severely affected

R is the resultant vector

This is a production problem which causes the bending of jigs unbalancing of the carrier thereby causing improper motion at the carrier turns and revolutions and also resulting in the body parts falling in the oven

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 65

Gear Box Failure

Gear box of the carrier also fails some time due to overloading or improper coupling

Bending of Striker

Overloading at CTs and CRs causes the bending of the strikers which result in altered motion of the carrier

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 66

Breaking of Post

The post of the carrier can be broken due to variable and unbalanced load acting on the carrier The stresses are developed in the post which leads to its breaking Moreover hammering of the nut for the proper locking can also cause the breaking of nut

Overloading

Overloading is the state when the load on a part of the carrier is higher than its tolerance value Its causes are

If any object interrupts the motion of chain chain is not able to move forward properly causing overloading of chain

Improper position of the jig may lead to unbalancing of the carrier and overload may occur

Guide pin may not properly interact with the arm which may lead to non-alignment

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 67

Chain of the carrier turn may not be in proper position leading to overload at CT

Breaking of any of the carrier dogs will lead to improper revolution of the carrier

Other Problems

Cable breaks -gt Current does not reach to body part

ED COLLECTER burns out -gt It would not collect current

Threading of endndashplate striker wear out -gt Striker would not hit limit switch

Bush between coupling is cut

Bearing sometimes disrupts system

Swivel pipe bends -gt Carrier wouldnrsquot be leveled

Insulator sometimes fails to stop current

End plate threading wears

Spindle shaft bends -gt Carrier wouldnrsquot be leveled

Striker and arm also bends

8 Introduction to Maintenance Department

Introduction The maintenance department is one of the most important departments of the organization where the organization has its own production Maintenance department of Honda Motorcycle and Scooter India Private Limited (HMSI) is a responsible for all the breakdowns which occur in the machines or where there is any production loss so when to overcome the problem of production loss maintenance team has to work efficiently so that there is no mistake committed by them by which production loss occurs

Some important definitions used by maintenance

Maintenance Action necessary for retaining or restoring an equipment machine or system to the specified operable condition to achieve its maximum useful life It includes planned and preventive maintenance

Planned Maintenance Preventive maintenance carried out according to a fixed plan is called planned maintenance

Preventive Maintenance Systematic inspection detection correction and prevention of incipient failures before they become actual or major failures is called as preventive maintenance

Breakdown Maintenance Repair or replacements performed after a machine has failed to return to its functional state following a malfunction or shutdown is called as breakdown maintenance

Predictive Maintenance Type of preventive maintenance performed continuously or at interval according to the requirement to diagnose and

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 36

monitor a condition or system also called condition based maintenance is called as predictive maintenance

Mean Time To Repair (MTTR) Basic measure of maintainability of repairable items it represents the average mean time required to repair a failed component or device is defined as mean time to repair

Mean Time Between Failures (MTBF) Basic measure of the reliability of repairable items it represents the average number of a life units during which all parts of a device or system perform within their specified limits under specified conditions are called as mean time between failures

Down Time Period during which an equipment or machine is not functional or cannot work It may be due to technical failures mechanical adjustments maintenance or non availability of inputs such as materials labor and power etc is called as down time

Frame Maintenance In this department there are three sections

1 Press Section

2 Weld Section

Engine Maintenance Frame Maintenance

3 Paint Section

PRESS SECTION Press section has mainly four machines

Komatsu Pressndash3

AIDA Press -1

CNC bending machine

Hind Press

These presses are mechanical presses and on this press mudguard fuel tank nose and body cover of the scooters like activa aviator dio shine twister unicorn and twister Process like blanking coining and bending of pipes is done

Blanking is cutting up a large sheer of stock into smaller pieces suitable for next operation

Coining is the process of removal of extra material or to make work piece up to the limit All these mechanical presses are of 500 ton and there only one hydraulic press and this press are used to repair the dyes

CNC pipe bending machines are used to bend the pipes which later used in the manufacturing of the frame

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 38

WELDING SECTION In welding section there are six types of welding machines used in manufacturing of frames and body covers

1 Gantry System Gantry system is a system in which gantry crane is used for transporting the frame and welding is done by the robots and welding is finished by the robots the gantry crane picks up the frame and body covers and puts them on the conveyer or the hanger which goes to the weld body storage On gantry system seam welding is done on the body covers and on the frames with the help of the welding robots This system is fully automatic and there is no involvement of human being it picks up the frame and body covers from the location defined to it then does all the processing on it and then passes it to the conveyer

2 MIG Welding Metal inert gas welding in this inert gas argon is used and argon acts as a shielding gas 1-5 oxygen is used This type of welding uses consumable wire electrode during the welding process that is fed from the wire spool MIG welding has some advantages over the other welding techniques It provides a uniform weld it provides a slag free weld beam and needs little clean up

3 Spot Welding Spot welding is a process in which contacting metal surface are joined by the heat obtained from resistance to electric flow and this type of welding is done on the body covers of the scooter

4 Seam Welding It is a process that welds at a surface of overlapped parts along a length of a joint Weld made by overlapping nuggets this type of welding is done on the fuel tanks and mudguards of scooter

5 Portable Spot Welding It is a portable gun which can be taken to specified range where other spot welding machine faces difficulty in welding This type of the welding is done on body covers of scooters

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 39

6 Fine Boring Fine boring is done on the frame where handle has to fit after fine boring handle is attached to it

When various operation of the welding on the different components of the scooter that is frame mudguard body covers and fuel tank is over then this welded body parts are loaded on to a conveyer hanger which takes these body parts to the weld body storage and in the weld body storage and in weld body storage there are three sections one for model 1 one for model 2 and the last for model 3 When welded body is loaded on to a conveyor then the person who loads these bodies on to the hanger select in which model hanger has to go and the selection is done with a selector switch present Up to 300 hangers can be stored in the storage area that means around 600 frames and 600 body covers can be stored in the weld storage area From storage area hangers move to the unloading area and from unloading area these body covers and frames are loaded on to a Carrier which takes them to the paint section Unloading of the frames and body covers depends on the requirement of the assembly line and which model they are making according to their requirement unloading of model frames and body covers is done Unloading of the model is again done by the selector switch that is when there is requirement of model 1 the person who unloads the frame presses model switch and from storage model 1 moves to the unloading area Similarly when there is requirement of model 2 then operator presses model 2 switch and same goes for the model 3 when the requirement is of model 3 the operator presses the model 3 switch and then from storage model 3 moves to unloading bay

PAINT SECTION Paint section is very important section In this section different treatments are done on the body covers and frames and it is a step by step process done as follows

Loading

Pre-Treatment

Electro-Deposition

ED Oven

Booth

Top Coat Oven

Inspection Zone

Unloading

PAINT PROCESS FLOW

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 41

1 Sanding Zone

2 Under Coat

3 Top Coat

Loading In this process frames and body covers are mounted on the carrier of the conveyor line There are two lines for the paint that is paint A line and paint B line both the lines are very much important because in A line loading of frames and front body left right cover and rear body covers are loaded and on B line mudguard and front cowl is loaded and after loading of these parts then the carrier moves to the pretreatment zone

Pre-Treatment In pre-treatment degreasing and dust cleaning is done In pre-treatment bodies have to undergo two operations first wasting with the soft water by this process degreasing is done and all the dust particles are removed from the frames and body covers In general first we get hard water is converted to soft water by ion exchange mechanism

Secondly on bodies and frames phosphate cleaning is done by this method any dust particle or any grease particle left on the frames and body cover is removed

Electro-Deposition In electro deposition carrier which carries frame and body covers turn down into the electro deposition chamber and in electro deposition chamber is filled with the base paint or primer When carrier turns down it strikes high voltage wire and it gets negatively charged and become cathode and paint in the chamber becomes anode then a uniform thin film of base paint is deposited on

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 42

the body covers and frames of the scooter This process is repeated twice and after that it is passed to ED oven

ED Oven In electro deposition oven base coat done on the frame and body covers is heated to 150 degree temperature and this base coat is dried here and after that is passed to paint booth

Paint Booth Paint booth has three sections first one is sanding zone second primary coat or under coat and third is top coat

In sanding zone sanding of the frames and body covers is done and after that it is sent to under coat zone in under coat zone single coat of the paint is done on frames and body covers and in this zone coat of paint is done with the help of robots and after that frames and body covers then sent to top coat zone here in this zone second coat of the paint is done and this second coat of paint is done with the operator and after that these frames and body covers are sent to top coat oven

Top Coat Oven In top coat oven these frames and body covers are heated up to 170 degree temperature and dried and then allowed to cool naturally to room temperature and from there it is sent to the inspection zone

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 43

Inspection Zone In inspection zone body covers and frames have to pass infra-red zone Here IR testing machine checks for irregularities in the paint done and after that these body covers and frames are manually checked by hand for any errors in the paint jobs Parts which pass these tests get the OK mark and move to unloading area

Unloading In this area unloading of frames and body covers takes place Frames and body covers having OK mark are loaded to the paint body store and body covers and frames not having OK mark on them are sent to the repair work station and there they fix the problems which frames and body covers have They are then unloaded and then loaded on to the hanger and the parts go to the paint body storage In storage final or finished body covers and frames are stored which from storage area moves to the final assembly line

9 ProjectProject Definition

To study the various parts of the carrier being used in the paint shop and its problem analysis

Project Introduction

Carrier is defined as a thing which supports or holds up a part during its movement It is used to carry parts to the paint shop where various processes can be performed Carrier forms the basis of the Paint Shop because the movement of the parts from one point to another in the paint shop takes place only due to carrier The parts are loaded on the carrier with the help of a jig and then the motion takes place

Paint shop carrier is the most important moving part in the paint process Most problems and the breakdowns in the paint shop occur due to the carrier only It causes loss to the net production Bends or breaks due to load of body part applied on carrier causes distortions which ultimately results in the breakdown

Carrier is a part of the conveyer system being used in the paint shop The other components of the conveyer system are the prime mover drive (works as the input motion source for chain) chain and chain track carrier carrier turn (for turning the carrier) carrier

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 45

revolution (for revolving the carrier) stopper (it temporarily stops the carrier on line) carrier locks auto feeder cylinders and drop lifters which support the motion of carrier

Part Description Of Carrier

Rail

Rail can be of two types ie pre rail and power rail Pre rail is used to drive trolley of the carrier Power rail is used to drive the conveyer system

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 46

Gear Box

Gear Box acts as a Speed Reducer It consists of a worm and worm-wheel arrangement which turns the axis of rotation by 90deg and reduces the speed of the parts The gear box is coupled with the small sprocket Gear transmits power to small sprocket which helps for carrier turn this is also called as reduction gear The relation between the torque and diameter of worm shaft is given by

T (Kg-m) = π16dsup3τ

where τ is the twisting moment

Velocity Ratio = 160

Tensile Strength of Material = 60 Kgmmsup2

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 47

Trolley

Problem Analysis Of Carrier

Frame Hole NG

During the motion of the carrier when it is suddenly stopped by the stopper vibrations are produced in it and the pin inserted in the hole of the frame enlarges the size of the hole thereby causing the problem of frame hole NG

To reduce this problem an anti back-up system is applied to reduce the vibrations The NG frame hole is repaired by welding a bush at the site of the hole which is a newly developed Kaizen

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 64

Problems Caused By Loading

Improper loading of the frame body on the carrier damages the insulator collar because an unbalanced force acts upon it and insulator collars being the non-metallic parts are severely affected

R is the resultant vector

This is a production problem which causes the bending of jigs unbalancing of the carrier thereby causing improper motion at the carrier turns and revolutions and also resulting in the body parts falling in the oven

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 65

Gear Box Failure

Gear box of the carrier also fails some time due to overloading or improper coupling

Bending of Striker

Overloading at CTs and CRs causes the bending of the strikers which result in altered motion of the carrier

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 66

Breaking of Post

The post of the carrier can be broken due to variable and unbalanced load acting on the carrier The stresses are developed in the post which leads to its breaking Moreover hammering of the nut for the proper locking can also cause the breaking of nut

Overloading

Overloading is the state when the load on a part of the carrier is higher than its tolerance value Its causes are

If any object interrupts the motion of chain chain is not able to move forward properly causing overloading of chain

Improper position of the jig may lead to unbalancing of the carrier and overload may occur

Guide pin may not properly interact with the arm which may lead to non-alignment

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 67

Chain of the carrier turn may not be in proper position leading to overload at CT

Breaking of any of the carrier dogs will lead to improper revolution of the carrier

Other Problems

Cable breaks -gt Current does not reach to body part

ED COLLECTER burns out -gt It would not collect current

Threading of endndashplate striker wear out -gt Striker would not hit limit switch

Bush between coupling is cut

Bearing sometimes disrupts system

Swivel pipe bends -gt Carrier wouldnrsquot be leveled

Insulator sometimes fails to stop current

End plate threading wears

Spindle shaft bends -gt Carrier wouldnrsquot be leveled

Striker and arm also bends

8 Introduction to Maintenance Department

Introduction The maintenance department is one of the most important departments of the organization where the organization has its own production Maintenance department of Honda Motorcycle and Scooter India Private Limited (HMSI) is a responsible for all the breakdowns which occur in the machines or where there is any production loss so when to overcome the problem of production loss maintenance team has to work efficiently so that there is no mistake committed by them by which production loss occurs

Some important definitions used by maintenance

Maintenance Action necessary for retaining or restoring an equipment machine or system to the specified operable condition to achieve its maximum useful life It includes planned and preventive maintenance

Planned Maintenance Preventive maintenance carried out according to a fixed plan is called planned maintenance

Preventive Maintenance Systematic inspection detection correction and prevention of incipient failures before they become actual or major failures is called as preventive maintenance

Breakdown Maintenance Repair or replacements performed after a machine has failed to return to its functional state following a malfunction or shutdown is called as breakdown maintenance

Predictive Maintenance Type of preventive maintenance performed continuously or at interval according to the requirement to diagnose and

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 36

monitor a condition or system also called condition based maintenance is called as predictive maintenance

Mean Time To Repair (MTTR) Basic measure of maintainability of repairable items it represents the average mean time required to repair a failed component or device is defined as mean time to repair

Mean Time Between Failures (MTBF) Basic measure of the reliability of repairable items it represents the average number of a life units during which all parts of a device or system perform within their specified limits under specified conditions are called as mean time between failures

Down Time Period during which an equipment or machine is not functional or cannot work It may be due to technical failures mechanical adjustments maintenance or non availability of inputs such as materials labor and power etc is called as down time

Frame Maintenance In this department there are three sections

1 Press Section

2 Weld Section

Engine Maintenance Frame Maintenance

3 Paint Section

PRESS SECTION Press section has mainly four machines

Komatsu Pressndash3

AIDA Press -1

CNC bending machine

Hind Press

These presses are mechanical presses and on this press mudguard fuel tank nose and body cover of the scooters like activa aviator dio shine twister unicorn and twister Process like blanking coining and bending of pipes is done

Blanking is cutting up a large sheer of stock into smaller pieces suitable for next operation

Coining is the process of removal of extra material or to make work piece up to the limit All these mechanical presses are of 500 ton and there only one hydraulic press and this press are used to repair the dyes

CNC pipe bending machines are used to bend the pipes which later used in the manufacturing of the frame

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 38

WELDING SECTION In welding section there are six types of welding machines used in manufacturing of frames and body covers

1 Gantry System Gantry system is a system in which gantry crane is used for transporting the frame and welding is done by the robots and welding is finished by the robots the gantry crane picks up the frame and body covers and puts them on the conveyer or the hanger which goes to the weld body storage On gantry system seam welding is done on the body covers and on the frames with the help of the welding robots This system is fully automatic and there is no involvement of human being it picks up the frame and body covers from the location defined to it then does all the processing on it and then passes it to the conveyer

2 MIG Welding Metal inert gas welding in this inert gas argon is used and argon acts as a shielding gas 1-5 oxygen is used This type of welding uses consumable wire electrode during the welding process that is fed from the wire spool MIG welding has some advantages over the other welding techniques It provides a uniform weld it provides a slag free weld beam and needs little clean up

3 Spot Welding Spot welding is a process in which contacting metal surface are joined by the heat obtained from resistance to electric flow and this type of welding is done on the body covers of the scooter

4 Seam Welding It is a process that welds at a surface of overlapped parts along a length of a joint Weld made by overlapping nuggets this type of welding is done on the fuel tanks and mudguards of scooter

5 Portable Spot Welding It is a portable gun which can be taken to specified range where other spot welding machine faces difficulty in welding This type of the welding is done on body covers of scooters

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 39

6 Fine Boring Fine boring is done on the frame where handle has to fit after fine boring handle is attached to it

When various operation of the welding on the different components of the scooter that is frame mudguard body covers and fuel tank is over then this welded body parts are loaded on to a conveyer hanger which takes these body parts to the weld body storage and in the weld body storage and in weld body storage there are three sections one for model 1 one for model 2 and the last for model 3 When welded body is loaded on to a conveyor then the person who loads these bodies on to the hanger select in which model hanger has to go and the selection is done with a selector switch present Up to 300 hangers can be stored in the storage area that means around 600 frames and 600 body covers can be stored in the weld storage area From storage area hangers move to the unloading area and from unloading area these body covers and frames are loaded on to a Carrier which takes them to the paint section Unloading of the frames and body covers depends on the requirement of the assembly line and which model they are making according to their requirement unloading of model frames and body covers is done Unloading of the model is again done by the selector switch that is when there is requirement of model 1 the person who unloads the frame presses model switch and from storage model 1 moves to the unloading area Similarly when there is requirement of model 2 then operator presses model 2 switch and same goes for the model 3 when the requirement is of model 3 the operator presses the model 3 switch and then from storage model 3 moves to unloading bay

PAINT PROCESS FLOW

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 41

1 Sanding Zone

2 Under Coat

3 Top Coat

Loading In this process frames and body covers are mounted on the carrier of the conveyor line There are two lines for the paint that is paint A line and paint B line both the lines are very much important because in A line loading of frames and front body left right cover and rear body covers are loaded and on B line mudguard and front cowl is loaded and after loading of these parts then the carrier moves to the pretreatment zone

Pre-Treatment In pre-treatment degreasing and dust cleaning is done In pre-treatment bodies have to undergo two operations first wasting with the soft water by this process degreasing is done and all the dust particles are removed from the frames and body covers In general first we get hard water is converted to soft water by ion exchange mechanism

Secondly on bodies and frames phosphate cleaning is done by this method any dust particle or any grease particle left on the frames and body cover is removed

Electro-Deposition In electro deposition carrier which carries frame and body covers turn down into the electro deposition chamber and in electro deposition chamber is filled with the base paint or primer When carrier turns down it strikes high voltage wire and it gets negatively charged and become cathode and paint in the chamber becomes anode then a uniform thin film of base paint is deposited on

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 42

the body covers and frames of the scooter This process is repeated twice and after that it is passed to ED oven

ED Oven In electro deposition oven base coat done on the frame and body covers is heated to 150 degree temperature and this base coat is dried here and after that is passed to paint booth

Paint Booth Paint booth has three sections first one is sanding zone second primary coat or under coat and third is top coat

In sanding zone sanding of the frames and body covers is done and after that it is sent to under coat zone in under coat zone single coat of the paint is done on frames and body covers and in this zone coat of paint is done with the help of robots and after that frames and body covers then sent to top coat zone here in this zone second coat of the paint is done and this second coat of paint is done with the operator and after that these frames and body covers are sent to top coat oven

Top Coat Oven In top coat oven these frames and body covers are heated up to 170 degree temperature and dried and then allowed to cool naturally to room temperature and from there it is sent to the inspection zone

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 43

Inspection Zone In inspection zone body covers and frames have to pass infra-red zone Here IR testing machine checks for irregularities in the paint done and after that these body covers and frames are manually checked by hand for any errors in the paint jobs Parts which pass these tests get the OK mark and move to unloading area

Unloading In this area unloading of frames and body covers takes place Frames and body covers having OK mark are loaded to the paint body store and body covers and frames not having OK mark on them are sent to the repair work station and there they fix the problems which frames and body covers have They are then unloaded and then loaded on to the hanger and the parts go to the paint body storage In storage final or finished body covers and frames are stored which from storage area moves to the final assembly line

9 ProjectProject Definition

To study the various parts of the carrier being used in the paint shop and its problem analysis

Project Introduction

Carrier is defined as a thing which supports or holds up a part during its movement It is used to carry parts to the paint shop where various processes can be performed Carrier forms the basis of the Paint Shop because the movement of the parts from one point to another in the paint shop takes place only due to carrier The parts are loaded on the carrier with the help of a jig and then the motion takes place

Paint shop carrier is the most important moving part in the paint process Most problems and the breakdowns in the paint shop occur due to the carrier only It causes loss to the net production Bends or breaks due to load of body part applied on carrier causes distortions which ultimately results in the breakdown

Carrier is a part of the conveyer system being used in the paint shop The other components of the conveyer system are the prime mover drive (works as the input motion source for chain) chain and chain track carrier carrier turn (for turning the carrier) carrier

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 45

revolution (for revolving the carrier) stopper (it temporarily stops the carrier on line) carrier locks auto feeder cylinders and drop lifters which support the motion of carrier

Part Description Of Carrier

Rail

Problem Analysis Of Carrier

Frame Hole NG

During the motion of the carrier when it is suddenly stopped by the stopper vibrations are produced in it and the pin inserted in the hole of the frame enlarges the size of the hole thereby causing the problem of frame hole NG

To reduce this problem an anti back-up system is applied to reduce the vibrations The NG frame hole is repaired by welding a bush at the site of the hole which is a newly developed Kaizen

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 64

Problems Caused By Loading

Improper loading of the frame body on the carrier damages the insulator collar because an unbalanced force acts upon it and insulator collars being the non-metallic parts are severely affected

R is the resultant vector

This is a production problem which causes the bending of jigs unbalancing of the carrier thereby causing improper motion at the carrier turns and revolutions and also resulting in the body parts falling in the oven

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 65

Gear Box Failure

Gear box of the carrier also fails some time due to overloading or improper coupling

Bending of Striker

Overloading at CTs and CRs causes the bending of the strikers which result in altered motion of the carrier

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 66

Breaking of Post

The post of the carrier can be broken due to variable and unbalanced load acting on the carrier The stresses are developed in the post which leads to its breaking Moreover hammering of the nut for the proper locking can also cause the breaking of nut

Overloading

Overloading is the state when the load on a part of the carrier is higher than its tolerance value Its causes are

If any object interrupts the motion of chain chain is not able to move forward properly causing overloading of chain

Improper position of the jig may lead to unbalancing of the carrier and overload may occur

Guide pin may not properly interact with the arm which may lead to non-alignment

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 67

Chain of the carrier turn may not be in proper position leading to overload at CT

Breaking of any of the carrier dogs will lead to improper revolution of the carrier

Other Problems

Cable breaks -gt Current does not reach to body part

ED COLLECTER burns out -gt It would not collect current

Threading of endndashplate striker wear out -gt Striker would not hit limit switch

Bush between coupling is cut

Bearing sometimes disrupts system

Swivel pipe bends -gt Carrier wouldnrsquot be leveled

Insulator sometimes fails to stop current

End plate threading wears

Spindle shaft bends -gt Carrier wouldnrsquot be leveled

Striker and arm also bends

8 Introduction to Maintenance Department

Introduction The maintenance department is one of the most important departments of the organization where the organization has its own production Maintenance department of Honda Motorcycle and Scooter India Private Limited (HMSI) is a responsible for all the breakdowns which occur in the machines or where there is any production loss so when to overcome the problem of production loss maintenance team has to work efficiently so that there is no mistake committed by them by which production loss occurs

Some important definitions used by maintenance

Maintenance Action necessary for retaining or restoring an equipment machine or system to the specified operable condition to achieve its maximum useful life It includes planned and preventive maintenance

Planned Maintenance Preventive maintenance carried out according to a fixed plan is called planned maintenance

Preventive Maintenance Systematic inspection detection correction and prevention of incipient failures before they become actual or major failures is called as preventive maintenance

Breakdown Maintenance Repair or replacements performed after a machine has failed to return to its functional state following a malfunction or shutdown is called as breakdown maintenance

Predictive Maintenance Type of preventive maintenance performed continuously or at interval according to the requirement to diagnose and

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 36

monitor a condition or system also called condition based maintenance is called as predictive maintenance

Mean Time To Repair (MTTR) Basic measure of maintainability of repairable items it represents the average mean time required to repair a failed component or device is defined as mean time to repair

Mean Time Between Failures (MTBF) Basic measure of the reliability of repairable items it represents the average number of a life units during which all parts of a device or system perform within their specified limits under specified conditions are called as mean time between failures

Down Time Period during which an equipment or machine is not functional or cannot work It may be due to technical failures mechanical adjustments maintenance or non availability of inputs such as materials labor and power etc is called as down time

Frame Maintenance In this department there are three sections

1 Press Section

2 Weld Section

Engine Maintenance Frame Maintenance

3 Paint Section

PRESS SECTION Press section has mainly four machines

Komatsu Pressndash3

AIDA Press -1

CNC bending machine

Hind Press

These presses are mechanical presses and on this press mudguard fuel tank nose and body cover of the scooters like activa aviator dio shine twister unicorn and twister Process like blanking coining and bending of pipes is done

Blanking is cutting up a large sheer of stock into smaller pieces suitable for next operation

Coining is the process of removal of extra material or to make work piece up to the limit All these mechanical presses are of 500 ton and there only one hydraulic press and this press are used to repair the dyes

CNC pipe bending machines are used to bend the pipes which later used in the manufacturing of the frame

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 38

WELDING SECTION In welding section there are six types of welding machines used in manufacturing of frames and body covers

1 Gantry System Gantry system is a system in which gantry crane is used for transporting the frame and welding is done by the robots and welding is finished by the robots the gantry crane picks up the frame and body covers and puts them on the conveyer or the hanger which goes to the weld body storage On gantry system seam welding is done on the body covers and on the frames with the help of the welding robots This system is fully automatic and there is no involvement of human being it picks up the frame and body covers from the location defined to it then does all the processing on it and then passes it to the conveyer

2 MIG Welding Metal inert gas welding in this inert gas argon is used and argon acts as a shielding gas 1-5 oxygen is used This type of welding uses consumable wire electrode during the welding process that is fed from the wire spool MIG welding has some advantages over the other welding techniques It provides a uniform weld it provides a slag free weld beam and needs little clean up

3 Spot Welding Spot welding is a process in which contacting metal surface are joined by the heat obtained from resistance to electric flow and this type of welding is done on the body covers of the scooter

4 Seam Welding It is a process that welds at a surface of overlapped parts along a length of a joint Weld made by overlapping nuggets this type of welding is done on the fuel tanks and mudguards of scooter

5 Portable Spot Welding It is a portable gun which can be taken to specified range where other spot welding machine faces difficulty in welding This type of the welding is done on body covers of scooters

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 39

6 Fine Boring Fine boring is done on the frame where handle has to fit after fine boring handle is attached to it

When various operation of the welding on the different components of the scooter that is frame mudguard body covers and fuel tank is over then this welded body parts are loaded on to a conveyer hanger which takes these body parts to the weld body storage and in the weld body storage and in weld body storage there are three sections one for model 1 one for model 2 and the last for model 3 When welded body is loaded on to a conveyor then the person who loads these bodies on to the hanger select in which model hanger has to go and the selection is done with a selector switch present Up to 300 hangers can be stored in the storage area that means around 600 frames and 600 body covers can be stored in the weld storage area From storage area hangers move to the unloading area and from unloading area these body covers and frames are loaded on to a Carrier which takes them to the paint section Unloading of the frames and body covers depends on the requirement of the assembly line and which model they are making according to their requirement unloading of model frames and body covers is done Unloading of the model is again done by the selector switch that is when there is requirement of model 1 the person who unloads the frame presses model switch and from storage model 1 moves to the unloading area Similarly when there is requirement of model 2 then operator presses model 2 switch and same goes for the model 3 when the requirement is of model 3 the operator presses the model 3 switch and then from storage model 3 moves to unloading bay

PAINT PROCESS FLOW

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 41

1 Sanding Zone

2 Under Coat

3 Top Coat

Loading In this process frames and body covers are mounted on the carrier of the conveyor line There are two lines for the paint that is paint A line and paint B line both the lines are very much important because in A line loading of frames and front body left right cover and rear body covers are loaded and on B line mudguard and front cowl is loaded and after loading of these parts then the carrier moves to the pretreatment zone

Pre-Treatment In pre-treatment degreasing and dust cleaning is done In pre-treatment bodies have to undergo two operations first wasting with the soft water by this process degreasing is done and all the dust particles are removed from the frames and body covers In general first we get hard water is converted to soft water by ion exchange mechanism

Secondly on bodies and frames phosphate cleaning is done by this method any dust particle or any grease particle left on the frames and body cover is removed

Electro-Deposition In electro deposition carrier which carries frame and body covers turn down into the electro deposition chamber and in electro deposition chamber is filled with the base paint or primer When carrier turns down it strikes high voltage wire and it gets negatively charged and become cathode and paint in the chamber becomes anode then a uniform thin film of base paint is deposited on

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 42

the body covers and frames of the scooter This process is repeated twice and after that it is passed to ED oven

ED Oven In electro deposition oven base coat done on the frame and body covers is heated to 150 degree temperature and this base coat is dried here and after that is passed to paint booth

Paint Booth Paint booth has three sections first one is sanding zone second primary coat or under coat and third is top coat

In sanding zone sanding of the frames and body covers is done and after that it is sent to under coat zone in under coat zone single coat of the paint is done on frames and body covers and in this zone coat of paint is done with the help of robots and after that frames and body covers then sent to top coat zone here in this zone second coat of the paint is done and this second coat of paint is done with the operator and after that these frames and body covers are sent to top coat oven

Top Coat Oven In top coat oven these frames and body covers are heated up to 170 degree temperature and dried and then allowed to cool naturally to room temperature and from there it is sent to the inspection zone

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 43

Inspection Zone In inspection zone body covers and frames have to pass infra-red zone Here IR testing machine checks for irregularities in the paint done and after that these body covers and frames are manually checked by hand for any errors in the paint jobs Parts which pass these tests get the OK mark and move to unloading area

Unloading In this area unloading of frames and body covers takes place Frames and body covers having OK mark are loaded to the paint body store and body covers and frames not having OK mark on them are sent to the repair work station and there they fix the problems which frames and body covers have They are then unloaded and then loaded on to the hanger and the parts go to the paint body storage In storage final or finished body covers and frames are stored which from storage area moves to the final assembly line

9 ProjectProject Definition

To study the various parts of the carrier being used in the paint shop and its problem analysis

Project Introduction

Carrier is defined as a thing which supports or holds up a part during its movement It is used to carry parts to the paint shop where various processes can be performed Carrier forms the basis of the Paint Shop because the movement of the parts from one point to another in the paint shop takes place only due to carrier The parts are loaded on the carrier with the help of a jig and then the motion takes place

Paint shop carrier is the most important moving part in the paint process Most problems and the breakdowns in the paint shop occur due to the carrier only It causes loss to the net production Bends or breaks due to load of body part applied on carrier causes distortions which ultimately results in the breakdown

Carrier is a part of the conveyer system being used in the paint shop The other components of the conveyer system are the prime mover drive (works as the input motion source for chain) chain and chain track carrier carrier turn (for turning the carrier) carrier

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 45

revolution (for revolving the carrier) stopper (it temporarily stops the carrier on line) carrier locks auto feeder cylinders and drop lifters which support the motion of carrier

Part Description Of Carrier

Rail

Problem Analysis Of Carrier

Frame Hole NG

During the motion of the carrier when it is suddenly stopped by the stopper vibrations are produced in it and the pin inserted in the hole of the frame enlarges the size of the hole thereby causing the problem of frame hole NG

To reduce this problem an anti back-up system is applied to reduce the vibrations The NG frame hole is repaired by welding a bush at the site of the hole which is a newly developed Kaizen

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 64

Problems Caused By Loading

Improper loading of the frame body on the carrier damages the insulator collar because an unbalanced force acts upon it and insulator collars being the non-metallic parts are severely affected

R is the resultant vector

This is a production problem which causes the bending of jigs unbalancing of the carrier thereby causing improper motion at the carrier turns and revolutions and also resulting in the body parts falling in the oven

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 65

Gear Box Failure

Gear box of the carrier also fails some time due to overloading or improper coupling

Bending of Striker

Overloading at CTs and CRs causes the bending of the strikers which result in altered motion of the carrier

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 66

Breaking of Post

The post of the carrier can be broken due to variable and unbalanced load acting on the carrier The stresses are developed in the post which leads to its breaking Moreover hammering of the nut for the proper locking can also cause the breaking of nut

Overloading

Overloading is the state when the load on a part of the carrier is higher than its tolerance value Its causes are

If any object interrupts the motion of chain chain is not able to move forward properly causing overloading of chain

Improper position of the jig may lead to unbalancing of the carrier and overload may occur

Guide pin may not properly interact with the arm which may lead to non-alignment

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 67

Chain of the carrier turn may not be in proper position leading to overload at CT

Breaking of any of the carrier dogs will lead to improper revolution of the carrier

Other Problems

Cable breaks -gt Current does not reach to body part

ED COLLECTER burns out -gt It would not collect current

Threading of endndashplate striker wear out -gt Striker would not hit limit switch

Bush between coupling is cut

Bearing sometimes disrupts system

Swivel pipe bends -gt Carrier wouldnrsquot be leveled

Insulator sometimes fails to stop current

End plate threading wears

Spindle shaft bends -gt Carrier wouldnrsquot be leveled

Striker and arm also bends

Conclusion

From my project of one month here in HMSI I came to know that how

work goes on in the organization As far as my project of study

maintenance and breakdown analysis of carrier is concerned I came to

know the importance of carrier in paint shop and the production

problems caused by the carrier in the industry The carrier being used in

the paint shop is the best possible system for proper painting of parts

By knowing the various specifications problems related to it can be

solved

8 Introduction to Maintenance Department

Introduction The maintenance department is one of the most important departments of the organization where the organization has its own production Maintenance department of Honda Motorcycle and Scooter India Private Limited (HMSI) is a responsible for all the breakdowns which occur in the machines or where there is any production loss so when to overcome the problem of production loss maintenance team has to work efficiently so that there is no mistake committed by them by which production loss occurs

Some important definitions used by maintenance

Maintenance Action necessary for retaining or restoring an equipment machine or system to the specified operable condition to achieve its maximum useful life It includes planned and preventive maintenance

Planned Maintenance Preventive maintenance carried out according to a fixed plan is called planned maintenance

Preventive Maintenance Systematic inspection detection correction and prevention of incipient failures before they become actual or major failures is called as preventive maintenance

Breakdown Maintenance Repair or replacements performed after a machine has failed to return to its functional state following a malfunction or shutdown is called as breakdown maintenance

Predictive Maintenance Type of preventive maintenance performed continuously or at interval according to the requirement to diagnose and

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 36

monitor a condition or system also called condition based maintenance is called as predictive maintenance

Mean Time To Repair (MTTR) Basic measure of maintainability of repairable items it represents the average mean time required to repair a failed component or device is defined as mean time to repair

Mean Time Between Failures (MTBF) Basic measure of the reliability of repairable items it represents the average number of a life units during which all parts of a device or system perform within their specified limits under specified conditions are called as mean time between failures

Down Time Period during which an equipment or machine is not functional or cannot work It may be due to technical failures mechanical adjustments maintenance or non availability of inputs such as materials labor and power etc is called as down time

Frame Maintenance In this department there are three sections

1 Press Section

2 Weld Section

3 Paint Section

PRESS SECTION Press section has mainly four machines

Komatsu Pressndash3

AIDA Press -1

CNC bending machine

Hind Press

These presses are mechanical presses and on this press mudguard fuel tank nose and body cover of the scooters like activa aviator dio shine twister unicorn and twister Process like blanking coining and bending of pipes is done

Blanking is cutting up a large sheer of stock into smaller pieces suitable for next operation

Coining is the process of removal of extra material or to make work piece up to the limit All these mechanical presses are of 500 ton and there only one hydraulic press and this press are used to repair the dyes

CNC pipe bending machines are used to bend the pipes which later used in the manufacturing of the frame

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 38

WELDING SECTION In welding section there are six types of welding machines used in manufacturing of frames and body covers

1 Gantry System Gantry system is a system in which gantry crane is used for transporting the frame and welding is done by the robots and welding is finished by the robots the gantry crane picks up the frame and body covers and puts them on the conveyer or the hanger which goes to the weld body storage On gantry system seam welding is done on the body covers and on the frames with the help of the welding robots This system is fully automatic and there is no involvement of human being it picks up the frame and body covers from the location defined to it then does all the processing on it and then passes it to the conveyer

2 MIG Welding Metal inert gas welding in this inert gas argon is used and argon acts as a shielding gas 1-5 oxygen is used This type of welding uses consumable wire electrode during the welding process that is fed from the wire spool MIG welding has some advantages over the other welding techniques It provides a uniform weld it provides a slag free weld beam and needs little clean up

3 Spot Welding Spot welding is a process in which contacting metal surface are joined by the heat obtained from resistance to electric flow and this type of welding is done on the body covers of the scooter

4 Seam Welding It is a process that welds at a surface of overlapped parts along a length of a joint Weld made by overlapping nuggets this type of welding is done on the fuel tanks and mudguards of scooter

5 Portable Spot Welding It is a portable gun which can be taken to specified range where other spot welding machine faces difficulty in welding This type of the welding is done on body covers of scooters

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 39

6 Fine Boring Fine boring is done on the frame where handle has to fit after fine boring handle is attached to it

When various operation of the welding on the different components of the scooter that is frame mudguard body covers and fuel tank is over then this welded body parts are loaded on to a conveyer hanger which takes these body parts to the weld body storage and in the weld body storage and in weld body storage there are three sections one for model 1 one for model 2 and the last for model 3 When welded body is loaded on to a conveyor then the person who loads these bodies on to the hanger select in which model hanger has to go and the selection is done with a selector switch present Up to 300 hangers can be stored in the storage area that means around 600 frames and 600 body covers can be stored in the weld storage area From storage area hangers move to the unloading area and from unloading area these body covers and frames are loaded on to a Carrier which takes them to the paint section Unloading of the frames and body covers depends on the requirement of the assembly line and which model they are making according to their requirement unloading of model frames and body covers is done Unloading of the model is again done by the selector switch that is when there is requirement of model 1 the person who unloads the frame presses model switch and from storage model 1 moves to the unloading area Similarly when there is requirement of model 2 then operator presses model 2 switch and same goes for the model 3 when the requirement is of model 3 the operator presses the model 3 switch and then from storage model 3 moves to unloading bay

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 41

1 Sanding Zone

2 Under Coat

3 Top Coat

Loading In this process frames and body covers are mounted on the carrier of the conveyor line There are two lines for the paint that is paint A line and paint B line both the lines are very much important because in A line loading of frames and front body left right cover and rear body covers are loaded and on B line mudguard and front cowl is loaded and after loading of these parts then the carrier moves to the pretreatment zone

Pre-Treatment In pre-treatment degreasing and dust cleaning is done In pre-treatment bodies have to undergo two operations first wasting with the soft water by this process degreasing is done and all the dust particles are removed from the frames and body covers In general first we get hard water is converted to soft water by ion exchange mechanism

Secondly on bodies and frames phosphate cleaning is done by this method any dust particle or any grease particle left on the frames and body cover is removed

Electro-Deposition In electro deposition carrier which carries frame and body covers turn down into the electro deposition chamber and in electro deposition chamber is filled with the base paint or primer When carrier turns down it strikes high voltage wire and it gets negatively charged and become cathode and paint in the chamber becomes anode then a uniform thin film of base paint is deposited on

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 42

the body covers and frames of the scooter This process is repeated twice and after that it is passed to ED oven

ED Oven In electro deposition oven base coat done on the frame and body covers is heated to 150 degree temperature and this base coat is dried here and after that is passed to paint booth

Paint Booth Paint booth has three sections first one is sanding zone second primary coat or under coat and third is top coat

In sanding zone sanding of the frames and body covers is done and after that it is sent to under coat zone in under coat zone single coat of the paint is done on frames and body covers and in this zone coat of paint is done with the help of robots and after that frames and body covers then sent to top coat zone here in this zone second coat of the paint is done and this second coat of paint is done with the operator and after that these frames and body covers are sent to top coat oven

Top Coat Oven In top coat oven these frames and body covers are heated up to 170 degree temperature and dried and then allowed to cool naturally to room temperature and from there it is sent to the inspection zone

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 43

Inspection Zone In inspection zone body covers and frames have to pass infra-red zone Here IR testing machine checks for irregularities in the paint done and after that these body covers and frames are manually checked by hand for any errors in the paint jobs Parts which pass these tests get the OK mark and move to unloading area

Unloading In this area unloading of frames and body covers takes place Frames and body covers having OK mark are loaded to the paint body store and body covers and frames not having OK mark on them are sent to the repair work station and there they fix the problems which frames and body covers have They are then unloaded and then loaded on to the hanger and the parts go to the paint body storage In storage final or finished body covers and frames are stored which from storage area moves to the final assembly line

9 ProjectProject Definition

To study the various parts of the carrier being used in the paint shop and its problem analysis

Project Introduction

Carrier is defined as a thing which supports or holds up a part during its movement It is used to carry parts to the paint shop where various processes can be performed Carrier forms the basis of the Paint Shop because the movement of the parts from one point to another in the paint shop takes place only due to carrier The parts are loaded on the carrier with the help of a jig and then the motion takes place

Paint shop carrier is the most important moving part in the paint process Most problems and the breakdowns in the paint shop occur due to the carrier only It causes loss to the net production Bends or breaks due to load of body part applied on carrier causes distortions which ultimately results in the breakdown

Carrier is a part of the conveyer system being used in the paint shop The other components of the conveyer system are the prime mover drive (works as the input motion source for chain) chain and chain track carrier carrier turn (for turning the carrier) carrier

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 45

revolution (for revolving the carrier) stopper (it temporarily stops the carrier on line) carrier locks auto feeder cylinders and drop lifters which support the motion of carrier

Part Description Of Carrier

Rail

Rail can be of two types ie pre rail and power rail Pre rail is used to drive trolley of the carrier Power rail is used to drive the conveyer system

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 46

Gear Box

Gear Box acts as a Speed Reducer It consists of a worm and worm-wheel arrangement which turns the axis of rotation by 90deg and reduces the speed of the parts The gear box is coupled with the small sprocket Gear transmits power to small sprocket which helps for carrier turn this is also called as reduction gear The relation between the torque and diameter of worm shaft is given by

T (Kg-m) = π16dsup3τ

where τ is the twisting moment

Velocity Ratio = 160

Tensile Strength of Material = 60 Kgmmsup2

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 47

Trolley

Problem Analysis Of Carrier

Frame Hole NG

During the motion of the carrier when it is suddenly stopped by the stopper vibrations are produced in it and the pin inserted in the hole of the frame enlarges the size of the hole thereby causing the problem of frame hole NG

To reduce this problem an anti back-up system is applied to reduce the vibrations The NG frame hole is repaired by welding a bush at the site of the hole which is a newly developed Kaizen

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 64

Problems Caused By Loading

Improper loading of the frame body on the carrier damages the insulator collar because an unbalanced force acts upon it and insulator collars being the non-metallic parts are severely affected

R is the resultant vector

This is a production problem which causes the bending of jigs unbalancing of the carrier thereby causing improper motion at the carrier turns and revolutions and also resulting in the body parts falling in the oven

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 65

Gear Box Failure

Gear box of the carrier also fails some time due to overloading or improper coupling

Bending of Striker

Overloading at CTs and CRs causes the bending of the strikers which result in altered motion of the carrier

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 66

Breaking of Post

The post of the carrier can be broken due to variable and unbalanced load acting on the carrier The stresses are developed in the post which leads to its breaking Moreover hammering of the nut for the proper locking can also cause the breaking of nut

Overloading

Overloading is the state when the load on a part of the carrier is higher than its tolerance value Its causes are

If any object interrupts the motion of chain chain is not able to move forward properly causing overloading of chain

Improper position of the jig may lead to unbalancing of the carrier and overload may occur

Guide pin may not properly interact with the arm which may lead to non-alignment

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 67

Chain of the carrier turn may not be in proper position leading to overload at CT

Breaking of any of the carrier dogs will lead to improper revolution of the carrier

Other Problems

Cable breaks -gt Current does not reach to body part

ED COLLECTER burns out -gt It would not collect current

Threading of endndashplate striker wear out -gt Striker would not hit limit switch

Bush between coupling is cut

Bearing sometimes disrupts system

Swivel pipe bends -gt Carrier wouldnrsquot be leveled

Insulator sometimes fails to stop current

End plate threading wears

Spindle shaft bends -gt Carrier wouldnrsquot be leveled

Striker and arm also bends

Conclusion

From my project of one month here in HMSI I came to know that how

work goes on in the organization As far as my project of study

maintenance and breakdown analysis of carrier is concerned I came to

know the importance of carrier in paint shop and the production

problems caused by the carrier in the industry The carrier being used in

the paint shop is the best possible system for proper painting of parts

By knowing the various specifications problems related to it can be

solved

8 Introduction to Maintenance Department

Introduction The maintenance department is one of the most important departments of the organization where the organization has its own production Maintenance department of Honda Motorcycle and Scooter India Private Limited (HMSI) is a responsible for all the breakdowns which occur in the machines or where there is any production loss so when to overcome the problem of production loss maintenance team has to work efficiently so that there is no mistake committed by them by which production loss occurs

Some important definitions used by maintenance

Maintenance Action necessary for retaining or restoring an equipment machine or system to the specified operable condition to achieve its maximum useful life It includes planned and preventive maintenance

Planned Maintenance Preventive maintenance carried out according to a fixed plan is called planned maintenance

Preventive Maintenance Systematic inspection detection correction and prevention of incipient failures before they become actual or major failures is called as preventive maintenance

Breakdown Maintenance Repair or replacements performed after a machine has failed to return to its functional state following a malfunction or shutdown is called as breakdown maintenance

Predictive Maintenance Type of preventive maintenance performed continuously or at interval according to the requirement to diagnose and

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 36

monitor a condition or system also called condition based maintenance is called as predictive maintenance

Mean Time To Repair (MTTR) Basic measure of maintainability of repairable items it represents the average mean time required to repair a failed component or device is defined as mean time to repair

Mean Time Between Failures (MTBF) Basic measure of the reliability of repairable items it represents the average number of a life units during which all parts of a device or system perform within their specified limits under specified conditions are called as mean time between failures

Down Time Period during which an equipment or machine is not functional or cannot work It may be due to technical failures mechanical adjustments maintenance or non availability of inputs such as materials labor and power etc is called as down time

Frame Maintenance In this department there are three sections

1 Press Section

2 Weld Section

Engine Maintenance Frame Maintenance

3 Paint Section

PRESS SECTION Press section has mainly four machines

Komatsu Pressndash3

AIDA Press -1

CNC bending machine

Hind Press

These presses are mechanical presses and on this press mudguard fuel tank nose and body cover of the scooters like activa aviator dio shine twister unicorn and twister Process like blanking coining and bending of pipes is done

Blanking is cutting up a large sheer of stock into smaller pieces suitable for next operation

Coining is the process of removal of extra material or to make work piece up to the limit All these mechanical presses are of 500 ton and there only one hydraulic press and this press are used to repair the dyes

CNC pipe bending machines are used to bend the pipes which later used in the manufacturing of the frame

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 38

WELDING SECTION In welding section there are six types of welding machines used in manufacturing of frames and body covers

1 Gantry System Gantry system is a system in which gantry crane is used for transporting the frame and welding is done by the robots and welding is finished by the robots the gantry crane picks up the frame and body covers and puts them on the conveyer or the hanger which goes to the weld body storage On gantry system seam welding is done on the body covers and on the frames with the help of the welding robots This system is fully automatic and there is no involvement of human being it picks up the frame and body covers from the location defined to it then does all the processing on it and then passes it to the conveyer

2 MIG Welding Metal inert gas welding in this inert gas argon is used and argon acts as a shielding gas 1-5 oxygen is used This type of welding uses consumable wire electrode during the welding process that is fed from the wire spool MIG welding has some advantages over the other welding techniques It provides a uniform weld it provides a slag free weld beam and needs little clean up

3 Spot Welding Spot welding is a process in which contacting metal surface are joined by the heat obtained from resistance to electric flow and this type of welding is done on the body covers of the scooter

4 Seam Welding It is a process that welds at a surface of overlapped parts along a length of a joint Weld made by overlapping nuggets this type of welding is done on the fuel tanks and mudguards of scooter

5 Portable Spot Welding It is a portable gun which can be taken to specified range where other spot welding machine faces difficulty in welding This type of the welding is done on body covers of scooters

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 39

6 Fine Boring Fine boring is done on the frame where handle has to fit after fine boring handle is attached to it

When various operation of the welding on the different components of the scooter that is frame mudguard body covers and fuel tank is over then this welded body parts are loaded on to a conveyer hanger which takes these body parts to the weld body storage and in the weld body storage and in weld body storage there are three sections one for model 1 one for model 2 and the last for model 3 When welded body is loaded on to a conveyor then the person who loads these bodies on to the hanger select in which model hanger has to go and the selection is done with a selector switch present Up to 300 hangers can be stored in the storage area that means around 600 frames and 600 body covers can be stored in the weld storage area From storage area hangers move to the unloading area and from unloading area these body covers and frames are loaded on to a Carrier which takes them to the paint section Unloading of the frames and body covers depends on the requirement of the assembly line and which model they are making according to their requirement unloading of model frames and body covers is done Unloading of the model is again done by the selector switch that is when there is requirement of model 1 the person who unloads the frame presses model switch and from storage model 1 moves to the unloading area Similarly when there is requirement of model 2 then operator presses model 2 switch and same goes for the model 3 when the requirement is of model 3 the operator presses the model 3 switch and then from storage model 3 moves to unloading bay

PAINT SECTION Paint section is very important section In this section different treatments are done on the body covers and frames and it is a step by step process done as follows

Loading

Pre-Treatment

Electro-Deposition

ED Oven

Booth

Top Coat Oven

Inspection Zone

Unloading

PAINT PROCESS FLOW

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 41

1 Sanding Zone

2 Under Coat

3 Top Coat

Loading In this process frames and body covers are mounted on the carrier of the conveyor line There are two lines for the paint that is paint A line and paint B line both the lines are very much important because in A line loading of frames and front body left right cover and rear body covers are loaded and on B line mudguard and front cowl is loaded and after loading of these parts then the carrier moves to the pretreatment zone

Pre-Treatment In pre-treatment degreasing and dust cleaning is done In pre-treatment bodies have to undergo two operations first wasting with the soft water by this process degreasing is done and all the dust particles are removed from the frames and body covers In general first we get hard water is converted to soft water by ion exchange mechanism

Secondly on bodies and frames phosphate cleaning is done by this method any dust particle or any grease particle left on the frames and body cover is removed

Electro-Deposition In electro deposition carrier which carries frame and body covers turn down into the electro deposition chamber and in electro deposition chamber is filled with the base paint or primer When carrier turns down it strikes high voltage wire and it gets negatively charged and become cathode and paint in the chamber becomes anode then a uniform thin film of base paint is deposited on

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 42

the body covers and frames of the scooter This process is repeated twice and after that it is passed to ED oven

ED Oven In electro deposition oven base coat done on the frame and body covers is heated to 150 degree temperature and this base coat is dried here and after that is passed to paint booth

Paint Booth Paint booth has three sections first one is sanding zone second primary coat or under coat and third is top coat

In sanding zone sanding of the frames and body covers is done and after that it is sent to under coat zone in under coat zone single coat of the paint is done on frames and body covers and in this zone coat of paint is done with the help of robots and after that frames and body covers then sent to top coat zone here in this zone second coat of the paint is done and this second coat of paint is done with the operator and after that these frames and body covers are sent to top coat oven

Top Coat Oven In top coat oven these frames and body covers are heated up to 170 degree temperature and dried and then allowed to cool naturally to room temperature and from there it is sent to the inspection zone

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 43

Inspection Zone In inspection zone body covers and frames have to pass infra-red zone Here IR testing machine checks for irregularities in the paint done and after that these body covers and frames are manually checked by hand for any errors in the paint jobs Parts which pass these tests get the OK mark and move to unloading area

Unloading In this area unloading of frames and body covers takes place Frames and body covers having OK mark are loaded to the paint body store and body covers and frames not having OK mark on them are sent to the repair work station and there they fix the problems which frames and body covers have They are then unloaded and then loaded on to the hanger and the parts go to the paint body storage In storage final or finished body covers and frames are stored which from storage area moves to the final assembly line

9 ProjectProject Definition

To study the various parts of the carrier being used in the paint shop and its problem analysis

Project Introduction

Carrier is defined as a thing which supports or holds up a part during its movement It is used to carry parts to the paint shop where various processes can be performed Carrier forms the basis of the Paint Shop because the movement of the parts from one point to another in the paint shop takes place only due to carrier The parts are loaded on the carrier with the help of a jig and then the motion takes place

Paint shop carrier is the most important moving part in the paint process Most problems and the breakdowns in the paint shop occur due to the carrier only It causes loss to the net production Bends or breaks due to load of body part applied on carrier causes distortions which ultimately results in the breakdown

Carrier is a part of the conveyer system being used in the paint shop The other components of the conveyer system are the prime mover drive (works as the input motion source for chain) chain and chain track carrier carrier turn (for turning the carrier) carrier

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 45

revolution (for revolving the carrier) stopper (it temporarily stops the carrier on line) carrier locks auto feeder cylinders and drop lifters which support the motion of carrier

Part Description Of Carrier

Rail

Rail can be of two types ie pre rail and power rail Pre rail is used to drive trolley of the carrier Power rail is used to drive the conveyer system

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 46

Gear Box

Gear Box acts as a Speed Reducer It consists of a worm and worm-wheel arrangement which turns the axis of rotation by 90deg and reduces the speed of the parts The gear box is coupled with the small sprocket Gear transmits power to small sprocket which helps for carrier turn this is also called as reduction gear The relation between the torque and diameter of worm shaft is given by

T (Kg-m) = π16dsup3τ

where τ is the twisting moment

Velocity Ratio = 160

Tensile Strength of Material = 60 Kgmmsup2

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 47

Trolley

Problem Analysis Of Carrier

Frame Hole NG

During the motion of the carrier when it is suddenly stopped by the stopper vibrations are produced in it and the pin inserted in the hole of the frame enlarges the size of the hole thereby causing the problem of frame hole NG

To reduce this problem an anti back-up system is applied to reduce the vibrations The NG frame hole is repaired by welding a bush at the site of the hole which is a newly developed Kaizen

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 64

Problems Caused By Loading

Improper loading of the frame body on the carrier damages the insulator collar because an unbalanced force acts upon it and insulator collars being the non-metallic parts are severely affected

R is the resultant vector

This is a production problem which causes the bending of jigs unbalancing of the carrier thereby causing improper motion at the carrier turns and revolutions and also resulting in the body parts falling in the oven

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 65

Gear Box Failure

Gear box of the carrier also fails some time due to overloading or improper coupling

Bending of Striker

Overloading at CTs and CRs causes the bending of the strikers which result in altered motion of the carrier

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 66

Breaking of Post

The post of the carrier can be broken due to variable and unbalanced load acting on the carrier The stresses are developed in the post which leads to its breaking Moreover hammering of the nut for the proper locking can also cause the breaking of nut

Overloading

Overloading is the state when the load on a part of the carrier is higher than its tolerance value Its causes are

If any object interrupts the motion of chain chain is not able to move forward properly causing overloading of chain

Improper position of the jig may lead to unbalancing of the carrier and overload may occur

Guide pin may not properly interact with the arm which may lead to non-alignment

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 67

Chain of the carrier turn may not be in proper position leading to overload at CT

Breaking of any of the carrier dogs will lead to improper revolution of the carrier

Other Problems

Cable breaks -gt Current does not reach to body part

ED COLLECTER burns out -gt It would not collect current

Threading of endndashplate striker wear out -gt Striker would not hit limit switch

Bush between coupling is cut

Bearing sometimes disrupts system

Swivel pipe bends -gt Carrier wouldnrsquot be leveled

Insulator sometimes fails to stop current

End plate threading wears

Spindle shaft bends -gt Carrier wouldnrsquot be leveled

Striker and arm also bends

8 Introduction to Maintenance Department

Introduction The maintenance department is one of the most important departments of the organization where the organization has its own production Maintenance department of Honda Motorcycle and Scooter India Private Limited (HMSI) is a responsible for all the breakdowns which occur in the machines or where there is any production loss so when to overcome the problem of production loss maintenance team has to work efficiently so that there is no mistake committed by them by which production loss occurs

Some important definitions used by maintenance

Maintenance Action necessary for retaining or restoring an equipment machine or system to the specified operable condition to achieve its maximum useful life It includes planned and preventive maintenance

Planned Maintenance Preventive maintenance carried out according to a fixed plan is called planned maintenance

Preventive Maintenance Systematic inspection detection correction and prevention of incipient failures before they become actual or major failures is called as preventive maintenance

Breakdown Maintenance Repair or replacements performed after a machine has failed to return to its functional state following a malfunction or shutdown is called as breakdown maintenance

Predictive Maintenance Type of preventive maintenance performed continuously or at interval according to the requirement to diagnose and

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 36

monitor a condition or system also called condition based maintenance is called as predictive maintenance

Mean Time To Repair (MTTR) Basic measure of maintainability of repairable items it represents the average mean time required to repair a failed component or device is defined as mean time to repair

Mean Time Between Failures (MTBF) Basic measure of the reliability of repairable items it represents the average number of a life units during which all parts of a device or system perform within their specified limits under specified conditions are called as mean time between failures

Down Time Period during which an equipment or machine is not functional or cannot work It may be due to technical failures mechanical adjustments maintenance or non availability of inputs such as materials labor and power etc is called as down time

Frame Maintenance In this department there are three sections

1 Press Section

2 Weld Section

Engine Maintenance Frame Maintenance

3 Paint Section

PRESS SECTION Press section has mainly four machines

Komatsu Pressndash3

AIDA Press -1

CNC bending machine

Hind Press

These presses are mechanical presses and on this press mudguard fuel tank nose and body cover of the scooters like activa aviator dio shine twister unicorn and twister Process like blanking coining and bending of pipes is done

Blanking is cutting up a large sheer of stock into smaller pieces suitable for next operation

Coining is the process of removal of extra material or to make work piece up to the limit All these mechanical presses are of 500 ton and there only one hydraulic press and this press are used to repair the dyes

CNC pipe bending machines are used to bend the pipes which later used in the manufacturing of the frame

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 38

WELDING SECTION In welding section there are six types of welding machines used in manufacturing of frames and body covers

1 Gantry System Gantry system is a system in which gantry crane is used for transporting the frame and welding is done by the robots and welding is finished by the robots the gantry crane picks up the frame and body covers and puts them on the conveyer or the hanger which goes to the weld body storage On gantry system seam welding is done on the body covers and on the frames with the help of the welding robots This system is fully automatic and there is no involvement of human being it picks up the frame and body covers from the location defined to it then does all the processing on it and then passes it to the conveyer

2 MIG Welding Metal inert gas welding in this inert gas argon is used and argon acts as a shielding gas 1-5 oxygen is used This type of welding uses consumable wire electrode during the welding process that is fed from the wire spool MIG welding has some advantages over the other welding techniques It provides a uniform weld it provides a slag free weld beam and needs little clean up

3 Spot Welding Spot welding is a process in which contacting metal surface are joined by the heat obtained from resistance to electric flow and this type of welding is done on the body covers of the scooter

4 Seam Welding It is a process that welds at a surface of overlapped parts along a length of a joint Weld made by overlapping nuggets this type of welding is done on the fuel tanks and mudguards of scooter

5 Portable Spot Welding It is a portable gun which can be taken to specified range where other spot welding machine faces difficulty in welding This type of the welding is done on body covers of scooters

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 39

6 Fine Boring Fine boring is done on the frame where handle has to fit after fine boring handle is attached to it

When various operation of the welding on the different components of the scooter that is frame mudguard body covers and fuel tank is over then this welded body parts are loaded on to a conveyer hanger which takes these body parts to the weld body storage and in the weld body storage and in weld body storage there are three sections one for model 1 one for model 2 and the last for model 3 When welded body is loaded on to a conveyor then the person who loads these bodies on to the hanger select in which model hanger has to go and the selection is done with a selector switch present Up to 300 hangers can be stored in the storage area that means around 600 frames and 600 body covers can be stored in the weld storage area From storage area hangers move to the unloading area and from unloading area these body covers and frames are loaded on to a Carrier which takes them to the paint section Unloading of the frames and body covers depends on the requirement of the assembly line and which model they are making according to their requirement unloading of model frames and body covers is done Unloading of the model is again done by the selector switch that is when there is requirement of model 1 the person who unloads the frame presses model switch and from storage model 1 moves to the unloading area Similarly when there is requirement of model 2 then operator presses model 2 switch and same goes for the model 3 when the requirement is of model 3 the operator presses the model 3 switch and then from storage model 3 moves to unloading bay

PAINT SECTION Paint section is very important section In this section different treatments are done on the body covers and frames and it is a step by step process done as follows

Loading

Pre-Treatment

Electro-Deposition

ED Oven

Booth

Top Coat Oven

Inspection Zone

Unloading

PAINT PROCESS FLOW

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 41

1 Sanding Zone

2 Under Coat

3 Top Coat

Loading In this process frames and body covers are mounted on the carrier of the conveyor line There are two lines for the paint that is paint A line and paint B line both the lines are very much important because in A line loading of frames and front body left right cover and rear body covers are loaded and on B line mudguard and front cowl is loaded and after loading of these parts then the carrier moves to the pretreatment zone

Pre-Treatment In pre-treatment degreasing and dust cleaning is done In pre-treatment bodies have to undergo two operations first wasting with the soft water by this process degreasing is done and all the dust particles are removed from the frames and body covers In general first we get hard water is converted to soft water by ion exchange mechanism

Secondly on bodies and frames phosphate cleaning is done by this method any dust particle or any grease particle left on the frames and body cover is removed

Electro-Deposition In electro deposition carrier which carries frame and body covers turn down into the electro deposition chamber and in electro deposition chamber is filled with the base paint or primer When carrier turns down it strikes high voltage wire and it gets negatively charged and become cathode and paint in the chamber becomes anode then a uniform thin film of base paint is deposited on

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 42

the body covers and frames of the scooter This process is repeated twice and after that it is passed to ED oven

ED Oven In electro deposition oven base coat done on the frame and body covers is heated to 150 degree temperature and this base coat is dried here and after that is passed to paint booth

Paint Booth Paint booth has three sections first one is sanding zone second primary coat or under coat and third is top coat

In sanding zone sanding of the frames and body covers is done and after that it is sent to under coat zone in under coat zone single coat of the paint is done on frames and body covers and in this zone coat of paint is done with the help of robots and after that frames and body covers then sent to top coat zone here in this zone second coat of the paint is done and this second coat of paint is done with the operator and after that these frames and body covers are sent to top coat oven

Top Coat Oven In top coat oven these frames and body covers are heated up to 170 degree temperature and dried and then allowed to cool naturally to room temperature and from there it is sent to the inspection zone

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 43

Inspection Zone In inspection zone body covers and frames have to pass infra-red zone Here IR testing machine checks for irregularities in the paint done and after that these body covers and frames are manually checked by hand for any errors in the paint jobs Parts which pass these tests get the OK mark and move to unloading area

Unloading In this area unloading of frames and body covers takes place Frames and body covers having OK mark are loaded to the paint body store and body covers and frames not having OK mark on them are sent to the repair work station and there they fix the problems which frames and body covers have They are then unloaded and then loaded on to the hanger and the parts go to the paint body storage In storage final or finished body covers and frames are stored which from storage area moves to the final assembly line

9 ProjectProject Definition

To study the various parts of the carrier being used in the paint shop and its problem analysis

Project Introduction

Carrier is defined as a thing which supports or holds up a part during its movement It is used to carry parts to the paint shop where various processes can be performed Carrier forms the basis of the Paint Shop because the movement of the parts from one point to another in the paint shop takes place only due to carrier The parts are loaded on the carrier with the help of a jig and then the motion takes place

Paint shop carrier is the most important moving part in the paint process Most problems and the breakdowns in the paint shop occur due to the carrier only It causes loss to the net production Bends or breaks due to load of body part applied on carrier causes distortions which ultimately results in the breakdown

Carrier is a part of the conveyer system being used in the paint shop The other components of the conveyer system are the prime mover drive (works as the input motion source for chain) chain and chain track carrier carrier turn (for turning the carrier) carrier

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 45

revolution (for revolving the carrier) stopper (it temporarily stops the carrier on line) carrier locks auto feeder cylinders and drop lifters which support the motion of carrier

Part Description Of Carrier

Rail

Problem Analysis Of Carrier

Frame Hole NG

During the motion of the carrier when it is suddenly stopped by the stopper vibrations are produced in it and the pin inserted in the hole of the frame enlarges the size of the hole thereby causing the problem of frame hole NG

To reduce this problem an anti back-up system is applied to reduce the vibrations The NG frame hole is repaired by welding a bush at the site of the hole which is a newly developed Kaizen

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 64

Problems Caused By Loading

Improper loading of the frame body on the carrier damages the insulator collar because an unbalanced force acts upon it and insulator collars being the non-metallic parts are severely affected

R is the resultant vector

This is a production problem which causes the bending of jigs unbalancing of the carrier thereby causing improper motion at the carrier turns and revolutions and also resulting in the body parts falling in the oven

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 65

Gear Box Failure

Gear box of the carrier also fails some time due to overloading or improper coupling

Bending of Striker

Overloading at CTs and CRs causes the bending of the strikers which result in altered motion of the carrier

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 66

Breaking of Post

The post of the carrier can be broken due to variable and unbalanced load acting on the carrier The stresses are developed in the post which leads to its breaking Moreover hammering of the nut for the proper locking can also cause the breaking of nut

Overloading

Overloading is the state when the load on a part of the carrier is higher than its tolerance value Its causes are

If any object interrupts the motion of chain chain is not able to move forward properly causing overloading of chain

Improper position of the jig may lead to unbalancing of the carrier and overload may occur

Guide pin may not properly interact with the arm which may lead to non-alignment

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 67

Chain of the carrier turn may not be in proper position leading to overload at CT

Breaking of any of the carrier dogs will lead to improper revolution of the carrier

Other Problems

Cable breaks -gt Current does not reach to body part

ED COLLECTER burns out -gt It would not collect current

Threading of endndashplate striker wear out -gt Striker would not hit limit switch

Bush between coupling is cut

Bearing sometimes disrupts system

Swivel pipe bends -gt Carrier wouldnrsquot be leveled

Insulator sometimes fails to stop current

End plate threading wears

Spindle shaft bends -gt Carrier wouldnrsquot be leveled

Striker and arm also bends

8 Introduction to Maintenance Department

Introduction The maintenance department is one of the most important departments of the organization where the organization has its own production Maintenance department of Honda Motorcycle and Scooter India Private Limited (HMSI) is a responsible for all the breakdowns which occur in the machines or where there is any production loss so when to overcome the problem of production loss maintenance team has to work efficiently so that there is no mistake committed by them by which production loss occurs

Some important definitions used by maintenance

Maintenance Action necessary for retaining or restoring an equipment machine or system to the specified operable condition to achieve its maximum useful life It includes planned and preventive maintenance

Planned Maintenance Preventive maintenance carried out according to a fixed plan is called planned maintenance

Preventive Maintenance Systematic inspection detection correction and prevention of incipient failures before they become actual or major failures is called as preventive maintenance

Breakdown Maintenance Repair or replacements performed after a machine has failed to return to its functional state following a malfunction or shutdown is called as breakdown maintenance

Predictive Maintenance Type of preventive maintenance performed continuously or at interval according to the requirement to diagnose and

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 36

monitor a condition or system also called condition based maintenance is called as predictive maintenance

Mean Time To Repair (MTTR) Basic measure of maintainability of repairable items it represents the average mean time required to repair a failed component or device is defined as mean time to repair

Mean Time Between Failures (MTBF) Basic measure of the reliability of repairable items it represents the average number of a life units during which all parts of a device or system perform within their specified limits under specified conditions are called as mean time between failures

Down Time Period during which an equipment or machine is not functional or cannot work It may be due to technical failures mechanical adjustments maintenance or non availability of inputs such as materials labor and power etc is called as down time

Frame Maintenance In this department there are three sections

1 Press Section

2 Weld Section

3 Paint Section

PRESS SECTION Press section has mainly four machines

Komatsu Pressndash3

AIDA Press -1

CNC bending machine

Hind Press

These presses are mechanical presses and on this press mudguard fuel tank nose and body cover of the scooters like activa aviator dio shine twister unicorn and twister Process like blanking coining and bending of pipes is done

Blanking is cutting up a large sheer of stock into smaller pieces suitable for next operation

Coining is the process of removal of extra material or to make work piece up to the limit All these mechanical presses are of 500 ton and there only one hydraulic press and this press are used to repair the dyes

CNC pipe bending machines are used to bend the pipes which later used in the manufacturing of the frame

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 38

WELDING SECTION In welding section there are six types of welding machines used in manufacturing of frames and body covers

1 Gantry System Gantry system is a system in which gantry crane is used for transporting the frame and welding is done by the robots and welding is finished by the robots the gantry crane picks up the frame and body covers and puts them on the conveyer or the hanger which goes to the weld body storage On gantry system seam welding is done on the body covers and on the frames with the help of the welding robots This system is fully automatic and there is no involvement of human being it picks up the frame and body covers from the location defined to it then does all the processing on it and then passes it to the conveyer

2 MIG Welding Metal inert gas welding in this inert gas argon is used and argon acts as a shielding gas 1-5 oxygen is used This type of welding uses consumable wire electrode during the welding process that is fed from the wire spool MIG welding has some advantages over the other welding techniques It provides a uniform weld it provides a slag free weld beam and needs little clean up

3 Spot Welding Spot welding is a process in which contacting metal surface are joined by the heat obtained from resistance to electric flow and this type of welding is done on the body covers of the scooter

4 Seam Welding It is a process that welds at a surface of overlapped parts along a length of a joint Weld made by overlapping nuggets this type of welding is done on the fuel tanks and mudguards of scooter

5 Portable Spot Welding It is a portable gun which can be taken to specified range where other spot welding machine faces difficulty in welding This type of the welding is done on body covers of scooters

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 39

6 Fine Boring Fine boring is done on the frame where handle has to fit after fine boring handle is attached to it

When various operation of the welding on the different components of the scooter that is frame mudguard body covers and fuel tank is over then this welded body parts are loaded on to a conveyer hanger which takes these body parts to the weld body storage and in the weld body storage and in weld body storage there are three sections one for model 1 one for model 2 and the last for model 3 When welded body is loaded on to a conveyor then the person who loads these bodies on to the hanger select in which model hanger has to go and the selection is done with a selector switch present Up to 300 hangers can be stored in the storage area that means around 600 frames and 600 body covers can be stored in the weld storage area From storage area hangers move to the unloading area and from unloading area these body covers and frames are loaded on to a Carrier which takes them to the paint section Unloading of the frames and body covers depends on the requirement of the assembly line and which model they are making according to their requirement unloading of model frames and body covers is done Unloading of the model is again done by the selector switch that is when there is requirement of model 1 the person who unloads the frame presses model switch and from storage model 1 moves to the unloading area Similarly when there is requirement of model 2 then operator presses model 2 switch and same goes for the model 3 when the requirement is of model 3 the operator presses the model 3 switch and then from storage model 3 moves to unloading bay

Top Coat Oven

Inspection Zone

Unloading

PAINT PROCESS FLOW

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 41

1 Sanding Zone

2 Under Coat

3 Top Coat

Loading In this process frames and body covers are mounted on the carrier of the conveyor line There are two lines for the paint that is paint A line and paint B line both the lines are very much important because in A line loading of frames and front body left right cover and rear body covers are loaded and on B line mudguard and front cowl is loaded and after loading of these parts then the carrier moves to the pretreatment zone

Pre-Treatment In pre-treatment degreasing and dust cleaning is done In pre-treatment bodies have to undergo two operations first wasting with the soft water by this process degreasing is done and all the dust particles are removed from the frames and body covers In general first we get hard water is converted to soft water by ion exchange mechanism

Secondly on bodies and frames phosphate cleaning is done by this method any dust particle or any grease particle left on the frames and body cover is removed

Electro-Deposition In electro deposition carrier which carries frame and body covers turn down into the electro deposition chamber and in electro deposition chamber is filled with the base paint or primer When carrier turns down it strikes high voltage wire and it gets negatively charged and become cathode and paint in the chamber becomes anode then a uniform thin film of base paint is deposited on

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 42

the body covers and frames of the scooter This process is repeated twice and after that it is passed to ED oven

ED Oven In electro deposition oven base coat done on the frame and body covers is heated to 150 degree temperature and this base coat is dried here and after that is passed to paint booth

Paint Booth Paint booth has three sections first one is sanding zone second primary coat or under coat and third is top coat

In sanding zone sanding of the frames and body covers is done and after that it is sent to under coat zone in under coat zone single coat of the paint is done on frames and body covers and in this zone coat of paint is done with the help of robots and after that frames and body covers then sent to top coat zone here in this zone second coat of the paint is done and this second coat of paint is done with the operator and after that these frames and body covers are sent to top coat oven

Top Coat Oven In top coat oven these frames and body covers are heated up to 170 degree temperature and dried and then allowed to cool naturally to room temperature and from there it is sent to the inspection zone

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 43

Inspection Zone In inspection zone body covers and frames have to pass infra-red zone Here IR testing machine checks for irregularities in the paint done and after that these body covers and frames are manually checked by hand for any errors in the paint jobs Parts which pass these tests get the OK mark and move to unloading area

Unloading In this area unloading of frames and body covers takes place Frames and body covers having OK mark are loaded to the paint body store and body covers and frames not having OK mark on them are sent to the repair work station and there they fix the problems which frames and body covers have They are then unloaded and then loaded on to the hanger and the parts go to the paint body storage In storage final or finished body covers and frames are stored which from storage area moves to the final assembly line

9 ProjectProject Definition

To study the various parts of the carrier being used in the paint shop and its problem analysis

Project Introduction

Carrier is defined as a thing which supports or holds up a part during its movement It is used to carry parts to the paint shop where various processes can be performed Carrier forms the basis of the Paint Shop because the movement of the parts from one point to another in the paint shop takes place only due to carrier The parts are loaded on the carrier with the help of a jig and then the motion takes place

Paint shop carrier is the most important moving part in the paint process Most problems and the breakdowns in the paint shop occur due to the carrier only It causes loss to the net production Bends or breaks due to load of body part applied on carrier causes distortions which ultimately results in the breakdown

Carrier is a part of the conveyer system being used in the paint shop The other components of the conveyer system are the prime mover drive (works as the input motion source for chain) chain and chain track carrier carrier turn (for turning the carrier) carrier

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 45

revolution (for revolving the carrier) stopper (it temporarily stops the carrier on line) carrier locks auto feeder cylinders and drop lifters which support the motion of carrier

Part Description Of Carrier

Rail

Rail can be of two types ie pre rail and power rail Pre rail is used to drive trolley of the carrier Power rail is used to drive the conveyer system

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 46

Gear Box

Gear Box acts as a Speed Reducer It consists of a worm and worm-wheel arrangement which turns the axis of rotation by 90deg and reduces the speed of the parts The gear box is coupled with the small sprocket Gear transmits power to small sprocket which helps for carrier turn this is also called as reduction gear The relation between the torque and diameter of worm shaft is given by

T (Kg-m) = π16dsup3τ

where τ is the twisting moment

Velocity Ratio = 160

Tensile Strength of Material = 60 Kgmmsup2

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 47

Trolley

Problem Analysis Of Carrier

Frame Hole NG

During the motion of the carrier when it is suddenly stopped by the stopper vibrations are produced in it and the pin inserted in the hole of the frame enlarges the size of the hole thereby causing the problem of frame hole NG

To reduce this problem an anti back-up system is applied to reduce the vibrations The NG frame hole is repaired by welding a bush at the site of the hole which is a newly developed Kaizen

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 64

Problems Caused By Loading

Improper loading of the frame body on the carrier damages the insulator collar because an unbalanced force acts upon it and insulator collars being the non-metallic parts are severely affected

R is the resultant vector

This is a production problem which causes the bending of jigs unbalancing of the carrier thereby causing improper motion at the carrier turns and revolutions and also resulting in the body parts falling in the oven

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 65

Gear Box Failure

Gear box of the carrier also fails some time due to overloading or improper coupling

Bending of Striker

Overloading at CTs and CRs causes the bending of the strikers which result in altered motion of the carrier

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 66

Breaking of Post

The post of the carrier can be broken due to variable and unbalanced load acting on the carrier The stresses are developed in the post which leads to its breaking Moreover hammering of the nut for the proper locking can also cause the breaking of nut

Overloading

Overloading is the state when the load on a part of the carrier is higher than its tolerance value Its causes are

If any object interrupts the motion of chain chain is not able to move forward properly causing overloading of chain

Improper position of the jig may lead to unbalancing of the carrier and overload may occur

Guide pin may not properly interact with the arm which may lead to non-alignment

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 67

Chain of the carrier turn may not be in proper position leading to overload at CT

Breaking of any of the carrier dogs will lead to improper revolution of the carrier

Other Problems

Cable breaks -gt Current does not reach to body part

ED COLLECTER burns out -gt It would not collect current

Threading of endndashplate striker wear out -gt Striker would not hit limit switch

Bush between coupling is cut

Bearing sometimes disrupts system

Swivel pipe bends -gt Carrier wouldnrsquot be leveled

Insulator sometimes fails to stop current

End plate threading wears

Spindle shaft bends -gt Carrier wouldnrsquot be leveled

Striker and arm also bends

8 Introduction to Maintenance Department

Introduction The maintenance department is one of the most important departments of the organization where the organization has its own production Maintenance department of Honda Motorcycle and Scooter India Private Limited (HMSI) is a responsible for all the breakdowns which occur in the machines or where there is any production loss so when to overcome the problem of production loss maintenance team has to work efficiently so that there is no mistake committed by them by which production loss occurs

Some important definitions used by maintenance

Maintenance Action necessary for retaining or restoring an equipment machine or system to the specified operable condition to achieve its maximum useful life It includes planned and preventive maintenance

Planned Maintenance Preventive maintenance carried out according to a fixed plan is called planned maintenance

Preventive Maintenance Systematic inspection detection correction and prevention of incipient failures before they become actual or major failures is called as preventive maintenance

Breakdown Maintenance Repair or replacements performed after a machine has failed to return to its functional state following a malfunction or shutdown is called as breakdown maintenance

Predictive Maintenance Type of preventive maintenance performed continuously or at interval according to the requirement to diagnose and

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 36

monitor a condition or system also called condition based maintenance is called as predictive maintenance

Mean Time To Repair (MTTR) Basic measure of maintainability of repairable items it represents the average mean time required to repair a failed component or device is defined as mean time to repair

Mean Time Between Failures (MTBF) Basic measure of the reliability of repairable items it represents the average number of a life units during which all parts of a device or system perform within their specified limits under specified conditions are called as mean time between failures

Down Time Period during which an equipment or machine is not functional or cannot work It may be due to technical failures mechanical adjustments maintenance or non availability of inputs such as materials labor and power etc is called as down time

Frame Maintenance In this department there are three sections

3 Paint Section

PRESS SECTION Press section has mainly four machines

Komatsu Pressndash3

AIDA Press -1

CNC bending machine

Hind Press

These presses are mechanical presses and on this press mudguard fuel tank nose and body cover of the scooters like activa aviator dio shine twister unicorn and twister Process like blanking coining and bending of pipes is done

Blanking is cutting up a large sheer of stock into smaller pieces suitable for next operation

Coining is the process of removal of extra material or to make work piece up to the limit All these mechanical presses are of 500 ton and there only one hydraulic press and this press are used to repair the dyes

CNC pipe bending machines are used to bend the pipes which later used in the manufacturing of the frame

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 38

WELDING SECTION In welding section there are six types of welding machines used in manufacturing of frames and body covers

1 Gantry System Gantry system is a system in which gantry crane is used for transporting the frame and welding is done by the robots and welding is finished by the robots the gantry crane picks up the frame and body covers and puts them on the conveyer or the hanger which goes to the weld body storage On gantry system seam welding is done on the body covers and on the frames with the help of the welding robots This system is fully automatic and there is no involvement of human being it picks up the frame and body covers from the location defined to it then does all the processing on it and then passes it to the conveyer

2 MIG Welding Metal inert gas welding in this inert gas argon is used and argon acts as a shielding gas 1-5 oxygen is used This type of welding uses consumable wire electrode during the welding process that is fed from the wire spool MIG welding has some advantages over the other welding techniques It provides a uniform weld it provides a slag free weld beam and needs little clean up

3 Spot Welding Spot welding is a process in which contacting metal surface are joined by the heat obtained from resistance to electric flow and this type of welding is done on the body covers of the scooter

4 Seam Welding It is a process that welds at a surface of overlapped parts along a length of a joint Weld made by overlapping nuggets this type of welding is done on the fuel tanks and mudguards of scooter

5 Portable Spot Welding It is a portable gun which can be taken to specified range where other spot welding machine faces difficulty in welding This type of the welding is done on body covers of scooters

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 39

6 Fine Boring Fine boring is done on the frame where handle has to fit after fine boring handle is attached to it

When various operation of the welding on the different components of the scooter that is frame mudguard body covers and fuel tank is over then this welded body parts are loaded on to a conveyer hanger which takes these body parts to the weld body storage and in the weld body storage and in weld body storage there are three sections one for model 1 one for model 2 and the last for model 3 When welded body is loaded on to a conveyor then the person who loads these bodies on to the hanger select in which model hanger has to go and the selection is done with a selector switch present Up to 300 hangers can be stored in the storage area that means around 600 frames and 600 body covers can be stored in the weld storage area From storage area hangers move to the unloading area and from unloading area these body covers and frames are loaded on to a Carrier which takes them to the paint section Unloading of the frames and body covers depends on the requirement of the assembly line and which model they are making according to their requirement unloading of model frames and body covers is done Unloading of the model is again done by the selector switch that is when there is requirement of model 1 the person who unloads the frame presses model switch and from storage model 1 moves to the unloading area Similarly when there is requirement of model 2 then operator presses model 2 switch and same goes for the model 3 when the requirement is of model 3 the operator presses the model 3 switch and then from storage model 3 moves to unloading bay

PAINT SECTION Paint section is very important section In this section different treatments are done on the body covers and frames and it is a step by step process done as follows

Loading

Pre-Treatment

Electro-Deposition

ED Oven

Booth

Top Coat Oven

Inspection Zone

Unloading

PAINT PROCESS FLOW

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 41

1 Sanding Zone

2 Under Coat

3 Top Coat

Loading In this process frames and body covers are mounted on the carrier of the conveyor line There are two lines for the paint that is paint A line and paint B line both the lines are very much important because in A line loading of frames and front body left right cover and rear body covers are loaded and on B line mudguard and front cowl is loaded and after loading of these parts then the carrier moves to the pretreatment zone

Pre-Treatment In pre-treatment degreasing and dust cleaning is done In pre-treatment bodies have to undergo two operations first wasting with the soft water by this process degreasing is done and all the dust particles are removed from the frames and body covers In general first we get hard water is converted to soft water by ion exchange mechanism

Secondly on bodies and frames phosphate cleaning is done by this method any dust particle or any grease particle left on the frames and body cover is removed

Electro-Deposition In electro deposition carrier which carries frame and body covers turn down into the electro deposition chamber and in electro deposition chamber is filled with the base paint or primer When carrier turns down it strikes high voltage wire and it gets negatively charged and become cathode and paint in the chamber becomes anode then a uniform thin film of base paint is deposited on

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 42

the body covers and frames of the scooter This process is repeated twice and after that it is passed to ED oven

ED Oven In electro deposition oven base coat done on the frame and body covers is heated to 150 degree temperature and this base coat is dried here and after that is passed to paint booth

Paint Booth Paint booth has three sections first one is sanding zone second primary coat or under coat and third is top coat

In sanding zone sanding of the frames and body covers is done and after that it is sent to under coat zone in under coat zone single coat of the paint is done on frames and body covers and in this zone coat of paint is done with the help of robots and after that frames and body covers then sent to top coat zone here in this zone second coat of the paint is done and this second coat of paint is done with the operator and after that these frames and body covers are sent to top coat oven

Top Coat Oven In top coat oven these frames and body covers are heated up to 170 degree temperature and dried and then allowed to cool naturally to room temperature and from there it is sent to the inspection zone

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 43

Inspection Zone In inspection zone body covers and frames have to pass infra-red zone Here IR testing machine checks for irregularities in the paint done and after that these body covers and frames are manually checked by hand for any errors in the paint jobs Parts which pass these tests get the OK mark and move to unloading area

Unloading In this area unloading of frames and body covers takes place Frames and body covers having OK mark are loaded to the paint body store and body covers and frames not having OK mark on them are sent to the repair work station and there they fix the problems which frames and body covers have They are then unloaded and then loaded on to the hanger and the parts go to the paint body storage In storage final or finished body covers and frames are stored which from storage area moves to the final assembly line

9 ProjectProject Definition

To study the various parts of the carrier being used in the paint shop and its problem analysis

Project Introduction

Carrier is defined as a thing which supports or holds up a part during its movement It is used to carry parts to the paint shop where various processes can be performed Carrier forms the basis of the Paint Shop because the movement of the parts from one point to another in the paint shop takes place only due to carrier The parts are loaded on the carrier with the help of a jig and then the motion takes place

Paint shop carrier is the most important moving part in the paint process Most problems and the breakdowns in the paint shop occur due to the carrier only It causes loss to the net production Bends or breaks due to load of body part applied on carrier causes distortions which ultimately results in the breakdown

Carrier is a part of the conveyer system being used in the paint shop The other components of the conveyer system are the prime mover drive (works as the input motion source for chain) chain and chain track carrier carrier turn (for turning the carrier) carrier

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 45

revolution (for revolving the carrier) stopper (it temporarily stops the carrier on line) carrier locks auto feeder cylinders and drop lifters which support the motion of carrier

Part Description Of Carrier

Rail

Problem Analysis Of Carrier

Frame Hole NG

During the motion of the carrier when it is suddenly stopped by the stopper vibrations are produced in it and the pin inserted in the hole of the frame enlarges the size of the hole thereby causing the problem of frame hole NG

To reduce this problem an anti back-up system is applied to reduce the vibrations The NG frame hole is repaired by welding a bush at the site of the hole which is a newly developed Kaizen

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 64

Problems Caused By Loading

Improper loading of the frame body on the carrier damages the insulator collar because an unbalanced force acts upon it and insulator collars being the non-metallic parts are severely affected

R is the resultant vector

This is a production problem which causes the bending of jigs unbalancing of the carrier thereby causing improper motion at the carrier turns and revolutions and also resulting in the body parts falling in the oven

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 65

Gear Box Failure

Gear box of the carrier also fails some time due to overloading or improper coupling

Bending of Striker

Overloading at CTs and CRs causes the bending of the strikers which result in altered motion of the carrier

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 66

Breaking of Post

The post of the carrier can be broken due to variable and unbalanced load acting on the carrier The stresses are developed in the post which leads to its breaking Moreover hammering of the nut for the proper locking can also cause the breaking of nut

Overloading

Overloading is the state when the load on a part of the carrier is higher than its tolerance value Its causes are

If any object interrupts the motion of chain chain is not able to move forward properly causing overloading of chain

Improper position of the jig may lead to unbalancing of the carrier and overload may occur

Guide pin may not properly interact with the arm which may lead to non-alignment

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 67

Chain of the carrier turn may not be in proper position leading to overload at CT

Breaking of any of the carrier dogs will lead to improper revolution of the carrier

Other Problems

Cable breaks -gt Current does not reach to body part

ED COLLECTER burns out -gt It would not collect current

Threading of endndashplate striker wear out -gt Striker would not hit limit switch

Bush between coupling is cut

Bearing sometimes disrupts system

Swivel pipe bends -gt Carrier wouldnrsquot be leveled

Insulator sometimes fails to stop current

End plate threading wears

Spindle shaft bends -gt Carrier wouldnrsquot be leveled

Striker and arm also bends

WELDING SECTION In welding section there are six types of welding machines used in manufacturing of frames and body covers

1 Gantry System Gantry system is a system in which gantry crane is used for transporting the frame and welding is done by the robots and welding is finished by the robots the gantry crane picks up the frame and body covers and puts them on the conveyer or the hanger which goes to the weld body storage On gantry system seam welding is done on the body covers and on the frames with the help of the welding robots This system is fully automatic and there is no involvement of human being it picks up the frame and body covers from the location defined to it then does all the processing on it and then passes it to the conveyer

2 MIG Welding Metal inert gas welding in this inert gas argon is used and argon acts as a shielding gas 1-5 oxygen is used This type of welding uses consumable wire electrode during the welding process that is fed from the wire spool MIG welding has some advantages over the other welding techniques It provides a uniform weld it provides a slag free weld beam and needs little clean up

3 Spot Welding Spot welding is a process in which contacting metal surface are joined by the heat obtained from resistance to electric flow and this type of welding is done on the body covers of the scooter

4 Seam Welding It is a process that welds at a surface of overlapped parts along a length of a joint Weld made by overlapping nuggets this type of welding is done on the fuel tanks and mudguards of scooter

5 Portable Spot Welding It is a portable gun which can be taken to specified range where other spot welding machine faces difficulty in welding This type of the welding is done on body covers of scooters

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 39

6 Fine Boring Fine boring is done on the frame where handle has to fit after fine boring handle is attached to it

When various operation of the welding on the different components of the scooter that is frame mudguard body covers and fuel tank is over then this welded body parts are loaded on to a conveyer hanger which takes these body parts to the weld body storage and in the weld body storage and in weld body storage there are three sections one for model 1 one for model 2 and the last for model 3 When welded body is loaded on to a conveyor then the person who loads these bodies on to the hanger select in which model hanger has to go and the selection is done with a selector switch present Up to 300 hangers can be stored in the storage area that means around 600 frames and 600 body covers can be stored in the weld storage area From storage area hangers move to the unloading area and from unloading area these body covers and frames are loaded on to a Carrier which takes them to the paint section Unloading of the frames and body covers depends on the requirement of the assembly line and which model they are making according to their requirement unloading of model frames and body covers is done Unloading of the model is again done by the selector switch that is when there is requirement of model 1 the person who unloads the frame presses model switch and from storage model 1 moves to the unloading area Similarly when there is requirement of model 2 then operator presses model 2 switch and same goes for the model 3 when the requirement is of model 3 the operator presses the model 3 switch and then from storage model 3 moves to unloading bay

PAINT SECTION Paint section is very important section In this section different treatments are done on the body covers and frames and it is a step by step process done as follows

Loading

Pre-Treatment

Electro-Deposition

ED Oven

Booth

Top Coat Oven

Inspection Zone

Unloading

PAINT PROCESS FLOW

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 41

1 Sanding Zone

2 Under Coat

3 Top Coat

Loading In this process frames and body covers are mounted on the carrier of the conveyor line There are two lines for the paint that is paint A line and paint B line both the lines are very much important because in A line loading of frames and front body left right cover and rear body covers are loaded and on B line mudguard and front cowl is loaded and after loading of these parts then the carrier moves to the pretreatment zone

Pre-Treatment In pre-treatment degreasing and dust cleaning is done In pre-treatment bodies have to undergo two operations first wasting with the soft water by this process degreasing is done and all the dust particles are removed from the frames and body covers In general first we get hard water is converted to soft water by ion exchange mechanism

Secondly on bodies and frames phosphate cleaning is done by this method any dust particle or any grease particle left on the frames and body cover is removed

Electro-Deposition In electro deposition carrier which carries frame and body covers turn down into the electro deposition chamber and in electro deposition chamber is filled with the base paint or primer When carrier turns down it strikes high voltage wire and it gets negatively charged and become cathode and paint in the chamber becomes anode then a uniform thin film of base paint is deposited on

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 42

the body covers and frames of the scooter This process is repeated twice and after that it is passed to ED oven

ED Oven In electro deposition oven base coat done on the frame and body covers is heated to 150 degree temperature and this base coat is dried here and after that is passed to paint booth

Paint Booth Paint booth has three sections first one is sanding zone second primary coat or under coat and third is top coat

In sanding zone sanding of the frames and body covers is done and after that it is sent to under coat zone in under coat zone single coat of the paint is done on frames and body covers and in this zone coat of paint is done with the help of robots and after that frames and body covers then sent to top coat zone here in this zone second coat of the paint is done and this second coat of paint is done with the operator and after that these frames and body covers are sent to top coat oven

Top Coat Oven In top coat oven these frames and body covers are heated up to 170 degree temperature and dried and then allowed to cool naturally to room temperature and from there it is sent to the inspection zone

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 43

Inspection Zone In inspection zone body covers and frames have to pass infra-red zone Here IR testing machine checks for irregularities in the paint done and after that these body covers and frames are manually checked by hand for any errors in the paint jobs Parts which pass these tests get the OK mark and move to unloading area

Unloading In this area unloading of frames and body covers takes place Frames and body covers having OK mark are loaded to the paint body store and body covers and frames not having OK mark on them are sent to the repair work station and there they fix the problems which frames and body covers have They are then unloaded and then loaded on to the hanger and the parts go to the paint body storage In storage final or finished body covers and frames are stored which from storage area moves to the final assembly line

9 ProjectProject Definition

To study the various parts of the carrier being used in the paint shop and its problem analysis

Project Introduction

Carrier is defined as a thing which supports or holds up a part during its movement It is used to carry parts to the paint shop where various processes can be performed Carrier forms the basis of the Paint Shop because the movement of the parts from one point to another in the paint shop takes place only due to carrier The parts are loaded on the carrier with the help of a jig and then the motion takes place

Paint shop carrier is the most important moving part in the paint process Most problems and the breakdowns in the paint shop occur due to the carrier only It causes loss to the net production Bends or breaks due to load of body part applied on carrier causes distortions which ultimately results in the breakdown

Carrier is a part of the conveyer system being used in the paint shop The other components of the conveyer system are the prime mover drive (works as the input motion source for chain) chain and chain track carrier carrier turn (for turning the carrier) carrier

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 45

revolution (for revolving the carrier) stopper (it temporarily stops the carrier on line) carrier locks auto feeder cylinders and drop lifters which support the motion of carrier

Part Description Of Carrier

Rail

Rail can be of two types ie pre rail and power rail Pre rail is used to drive trolley of the carrier Power rail is used to drive the conveyer system

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 46

Gear Box

Gear Box acts as a Speed Reducer It consists of a worm and worm-wheel arrangement which turns the axis of rotation by 90deg and reduces the speed of the parts The gear box is coupled with the small sprocket Gear transmits power to small sprocket which helps for carrier turn this is also called as reduction gear The relation between the torque and diameter of worm shaft is given by

T (Kg-m) = π16dsup3τ

where τ is the twisting moment

Velocity Ratio = 160

Tensile Strength of Material = 60 Kgmmsup2

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 47

Trolley

Problem Analysis Of Carrier

Frame Hole NG

During the motion of the carrier when it is suddenly stopped by the stopper vibrations are produced in it and the pin inserted in the hole of the frame enlarges the size of the hole thereby causing the problem of frame hole NG

To reduce this problem an anti back-up system is applied to reduce the vibrations The NG frame hole is repaired by welding a bush at the site of the hole which is a newly developed Kaizen

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 64

Problems Caused By Loading

Improper loading of the frame body on the carrier damages the insulator collar because an unbalanced force acts upon it and insulator collars being the non-metallic parts are severely affected

R is the resultant vector

This is a production problem which causes the bending of jigs unbalancing of the carrier thereby causing improper motion at the carrier turns and revolutions and also resulting in the body parts falling in the oven

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 65

Gear Box Failure

Gear box of the carrier also fails some time due to overloading or improper coupling

Bending of Striker

Overloading at CTs and CRs causes the bending of the strikers which result in altered motion of the carrier

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 66

Breaking of Post

The post of the carrier can be broken due to variable and unbalanced load acting on the carrier The stresses are developed in the post which leads to its breaking Moreover hammering of the nut for the proper locking can also cause the breaking of nut

Overloading

Overloading is the state when the load on a part of the carrier is higher than its tolerance value Its causes are

If any object interrupts the motion of chain chain is not able to move forward properly causing overloading of chain

Improper position of the jig may lead to unbalancing of the carrier and overload may occur

Guide pin may not properly interact with the arm which may lead to non-alignment

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 67

Chain of the carrier turn may not be in proper position leading to overload at CT

Breaking of any of the carrier dogs will lead to improper revolution of the carrier

Other Problems

Cable breaks -gt Current does not reach to body part

ED COLLECTER burns out -gt It would not collect current

Threading of endndashplate striker wear out -gt Striker would not hit limit switch

Bush between coupling is cut

Bearing sometimes disrupts system

Swivel pipe bends -gt Carrier wouldnrsquot be leveled

Insulator sometimes fails to stop current

End plate threading wears

Spindle shaft bends -gt Carrier wouldnrsquot be leveled

Striker and arm also bends

8 Introduction to Maintenance Department

Introduction The maintenance department is one of the most important departments of the organization where the organization has its own production Maintenance department of Honda Motorcycle and Scooter India Private Limited (HMSI) is a responsible for all the breakdowns which occur in the machines or where there is any production loss so when to overcome the problem of production loss maintenance team has to work efficiently so that there is no mistake committed by them by which production loss occurs

Some important definitions used by maintenance

Maintenance Action necessary for retaining or restoring an equipment machine or system to the specified operable condition to achieve its maximum useful life It includes planned and preventive maintenance

Planned Maintenance Preventive maintenance carried out according to a fixed plan is called planned maintenance

Preventive Maintenance Systematic inspection detection correction and prevention of incipient failures before they become actual or major failures is called as preventive maintenance

Breakdown Maintenance Repair or replacements performed after a machine has failed to return to its functional state following a malfunction or shutdown is called as breakdown maintenance

Predictive Maintenance Type of preventive maintenance performed continuously or at interval according to the requirement to diagnose and

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 36

monitor a condition or system also called condition based maintenance is called as predictive maintenance

Mean Time To Repair (MTTR) Basic measure of maintainability of repairable items it represents the average mean time required to repair a failed component or device is defined as mean time to repair

Mean Time Between Failures (MTBF) Basic measure of the reliability of repairable items it represents the average number of a life units during which all parts of a device or system perform within their specified limits under specified conditions are called as mean time between failures

Down Time Period during which an equipment or machine is not functional or cannot work It may be due to technical failures mechanical adjustments maintenance or non availability of inputs such as materials labor and power etc is called as down time

Frame Maintenance In this department there are three sections

1 Press Section

2 Weld Section

Engine Maintenance Frame Maintenance

3 Paint Section

PRESS SECTION Press section has mainly four machines

Komatsu Pressndash3

AIDA Press -1

CNC bending machine

Hind Press

These presses are mechanical presses and on this press mudguard fuel tank nose and body cover of the scooters like activa aviator dio shine twister unicorn and twister Process like blanking coining and bending of pipes is done

Blanking is cutting up a large sheer of stock into smaller pieces suitable for next operation

Coining is the process of removal of extra material or to make work piece up to the limit All these mechanical presses are of 500 ton and there only one hydraulic press and this press are used to repair the dyes

CNC pipe bending machines are used to bend the pipes which later used in the manufacturing of the frame

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 38

WELDING SECTION In welding section there are six types of welding machines used in manufacturing of frames and body covers

1 Gantry System Gantry system is a system in which gantry crane is used for transporting the frame and welding is done by the robots and welding is finished by the robots the gantry crane picks up the frame and body covers and puts them on the conveyer or the hanger which goes to the weld body storage On gantry system seam welding is done on the body covers and on the frames with the help of the welding robots This system is fully automatic and there is no involvement of human being it picks up the frame and body covers from the location defined to it then does all the processing on it and then passes it to the conveyer

2 MIG Welding Metal inert gas welding in this inert gas argon is used and argon acts as a shielding gas 1-5 oxygen is used This type of welding uses consumable wire electrode during the welding process that is fed from the wire spool MIG welding has some advantages over the other welding techniques It provides a uniform weld it provides a slag free weld beam and needs little clean up

3 Spot Welding Spot welding is a process in which contacting metal surface are joined by the heat obtained from resistance to electric flow and this type of welding is done on the body covers of the scooter

4 Seam Welding It is a process that welds at a surface of overlapped parts along a length of a joint Weld made by overlapping nuggets this type of welding is done on the fuel tanks and mudguards of scooter

5 Portable Spot Welding It is a portable gun which can be taken to specified range where other spot welding machine faces difficulty in welding This type of the welding is done on body covers of scooters

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 39

6 Fine Boring Fine boring is done on the frame where handle has to fit after fine boring handle is attached to it

When various operation of the welding on the different components of the scooter that is frame mudguard body covers and fuel tank is over then this welded body parts are loaded on to a conveyer hanger which takes these body parts to the weld body storage and in the weld body storage and in weld body storage there are three sections one for model 1 one for model 2 and the last for model 3 When welded body is loaded on to a conveyor then the person who loads these bodies on to the hanger select in which model hanger has to go and the selection is done with a selector switch present Up to 300 hangers can be stored in the storage area that means around 600 frames and 600 body covers can be stored in the weld storage area From storage area hangers move to the unloading area and from unloading area these body covers and frames are loaded on to a Carrier which takes them to the paint section Unloading of the frames and body covers depends on the requirement of the assembly line and which model they are making according to their requirement unloading of model frames and body covers is done Unloading of the model is again done by the selector switch that is when there is requirement of model 1 the person who unloads the frame presses model switch and from storage model 1 moves to the unloading area Similarly when there is requirement of model 2 then operator presses model 2 switch and same goes for the model 3 when the requirement is of model 3 the operator presses the model 3 switch and then from storage model 3 moves to unloading bay

Loading In this process frames and body covers are mounted on the carrier of the conveyor line There are two lines for the paint that is paint A line and paint B line both the lines are very much important because in A line loading of frames and front body left right cover and rear body covers are loaded and on B line mudguard and front cowl is loaded and after loading of these parts then the carrier moves to the pretreatment zone

Pre-Treatment In pre-treatment degreasing and dust cleaning is done In pre-treatment bodies have to undergo two operations first wasting with the soft water by this process degreasing is done and all the dust particles are removed from the frames and body covers In general first we get hard water is converted to soft water by ion exchange mechanism

Secondly on bodies and frames phosphate cleaning is done by this method any dust particle or any grease particle left on the frames and body cover is removed

Electro-Deposition In electro deposition carrier which carries frame and body covers turn down into the electro deposition chamber and in electro deposition chamber is filled with the base paint or primer When carrier turns down it strikes high voltage wire and it gets negatively charged and become cathode and paint in the chamber becomes anode then a uniform thin film of base paint is deposited on

the body covers and frames of the scooter This process is repeated twice and after that it is passed to ED oven

ED Oven In electro deposition oven base coat done on the frame and body covers is heated to 150 degree temperature and this base coat is dried here and after that is passed to paint booth

Paint Booth Paint booth has three sections first one is sanding zone second primary coat or under coat and third is top coat

In sanding zone sanding of the frames and body covers is done and after that it is sent to under coat zone in under coat zone single coat of the paint is done on frames and body covers and in this zone coat of paint is done with the help of robots and after that frames and body covers then sent to top coat zone here in this zone second coat of the paint is done and this second coat of paint is done with the operator and after that these frames and body covers are sent to top coat oven

Top Coat Oven In top coat oven these frames and body covers are heated up to 170 degree temperature and dried and then allowed to cool naturally to room temperature and from there it is sent to the inspection zone

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 43

Inspection Zone In inspection zone body covers and frames have to pass infra-red zone Here IR testing machine checks for irregularities in the paint done and after that these body covers and frames are manually checked by hand for any errors in the paint jobs Parts which pass these tests get the OK mark and move to unloading area

Unloading In this area unloading of frames and body covers takes place Frames and body covers having OK mark are loaded to the paint body store and body covers and frames not having OK mark on them are sent to the repair work station and there they fix the problems which frames and body covers have They are then unloaded and then loaded on to the hanger and the parts go to the paint body storage In storage final or finished body covers and frames are stored which from storage area moves to the final assembly line

9 ProjectProject Definition

To study the various parts of the carrier being used in the paint shop and its problem analysis

Project Introduction

Carrier is defined as a thing which supports or holds up a part during its movement It is used to carry parts to the paint shop where various processes can be performed Carrier forms the basis of the Paint Shop because the movement of the parts from one point to another in the paint shop takes place only due to carrier The parts are loaded on the carrier with the help of a jig and then the motion takes place

Paint shop carrier is the most important moving part in the paint process Most problems and the breakdowns in the paint shop occur due to the carrier only It causes loss to the net production Bends or breaks due to load of body part applied on carrier causes distortions which ultimately results in the breakdown

Carrier is a part of the conveyer system being used in the paint shop The other components of the conveyer system are the prime mover drive (works as the input motion source for chain) chain and chain track carrier carrier turn (for turning the carrier) carrier

Problem Analysis Of Carrier

Frame Hole NG

During the motion of the carrier when it is suddenly stopped by the stopper vibrations are produced in it and the pin inserted in the hole of the frame enlarges the size of the hole thereby causing the problem of frame hole NG

To reduce this problem an anti back-up system is applied to reduce the vibrations The NG frame hole is repaired by welding a bush at the site of the hole which is a newly developed Kaizen

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 64

Problems Caused By Loading

Improper loading of the frame body on the carrier damages the insulator collar because an unbalanced force acts upon it and insulator collars being the non-metallic parts are severely affected

R is the resultant vector

This is a production problem which causes the bending of jigs unbalancing of the carrier thereby causing improper motion at the carrier turns and revolutions and also resulting in the body parts falling in the oven

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 65

Gear Box Failure

Gear box of the carrier also fails some time due to overloading or improper coupling

Bending of Striker

Overloading at CTs and CRs causes the bending of the strikers which result in altered motion of the carrier

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 66

Breaking of Post

The post of the carrier can be broken due to variable and unbalanced load acting on the carrier The stresses are developed in the post which leads to its breaking Moreover hammering of the nut for the proper locking can also cause the breaking of nut

Overloading

Overloading is the state when the load on a part of the carrier is higher than its tolerance value Its causes are

If any object interrupts the motion of chain chain is not able to move forward properly causing overloading of chain

Improper position of the jig may lead to unbalancing of the carrier and overload may occur

Guide pin may not properly interact with the arm which may lead to non-alignment

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 67

Chain of the carrier turn may not be in proper position leading to overload at CT

Breaking of any of the carrier dogs will lead to improper revolution of the carrier

Other Problems

Cable breaks -gt Current does not reach to body part

ED COLLECTER burns out -gt It would not collect current

Threading of endndashplate striker wear out -gt Striker would not hit limit switch

Bush between coupling is cut

Bearing sometimes disrupts system

Swivel pipe bends -gt Carrier wouldnrsquot be leveled

Insulator sometimes fails to stop current

End plate threading wears

Spindle shaft bends -gt Carrier wouldnrsquot be leveled

Striker and arm also bends

8 Introduction to Maintenance Department

Introduction The maintenance department is one of the most important departments of the organization where the organization has its own production Maintenance department of Honda Motorcycle and Scooter India Private Limited (HMSI) is a responsible for all the breakdowns which occur in the machines or where there is any production loss so when to overcome the problem of production loss maintenance team has to work efficiently so that there is no mistake committed by them by which production loss occurs

Some important definitions used by maintenance

Maintenance Action necessary for retaining or restoring an equipment machine or system to the specified operable condition to achieve its maximum useful life It includes planned and preventive maintenance

Planned Maintenance Preventive maintenance carried out according to a fixed plan is called planned maintenance

Preventive Maintenance Systematic inspection detection correction and prevention of incipient failures before they become actual or major failures is called as preventive maintenance

Breakdown Maintenance Repair or replacements performed after a machine has failed to return to its functional state following a malfunction or shutdown is called as breakdown maintenance

Predictive Maintenance Type of preventive maintenance performed continuously or at interval according to the requirement to diagnose and

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 36

monitor a condition or system also called condition based maintenance is called as predictive maintenance

Mean Time To Repair (MTTR) Basic measure of maintainability of repairable items it represents the average mean time required to repair a failed component or device is defined as mean time to repair

Mean Time Between Failures (MTBF) Basic measure of the reliability of repairable items it represents the average number of a life units during which all parts of a device or system perform within their specified limits under specified conditions are called as mean time between failures

Down Time Period during which an equipment or machine is not functional or cannot work It may be due to technical failures mechanical adjustments maintenance or non availability of inputs such as materials labor and power etc is called as down time

Frame Maintenance In this department there are three sections

1 Press Section

2 Weld Section

3 Paint Section

PRESS SECTION Press section has mainly four machines

Komatsu Pressndash3

AIDA Press -1

CNC bending machine

Hind Press

These presses are mechanical presses and on this press mudguard fuel tank nose and body cover of the scooters like activa aviator dio shine twister unicorn and twister Process like blanking coining and bending of pipes is done

Blanking is cutting up a large sheer of stock into smaller pieces suitable for next operation

Coining is the process of removal of extra material or to make work piece up to the limit All these mechanical presses are of 500 ton and there only one hydraulic press and this press are used to repair the dyes

CNC pipe bending machines are used to bend the pipes which later used in the manufacturing of the frame

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 38

WELDING SECTION In welding section there are six types of welding machines used in manufacturing of frames and body covers

1 Gantry System Gantry system is a system in which gantry crane is used for transporting the frame and welding is done by the robots and welding is finished by the robots the gantry crane picks up the frame and body covers and puts them on the conveyer or the hanger which goes to the weld body storage On gantry system seam welding is done on the body covers and on the frames with the help of the welding robots This system is fully automatic and there is no involvement of human being it picks up the frame and body covers from the location defined to it then does all the processing on it and then passes it to the conveyer

2 MIG Welding Metal inert gas welding in this inert gas argon is used and argon acts as a shielding gas 1-5 oxygen is used This type of welding uses consumable wire electrode during the welding process that is fed from the wire spool MIG welding has some advantages over the other welding techniques It provides a uniform weld it provides a slag free weld beam and needs little clean up

3 Spot Welding Spot welding is a process in which contacting metal surface are joined by the heat obtained from resistance to electric flow and this type of welding is done on the body covers of the scooter

4 Seam Welding It is a process that welds at a surface of overlapped parts along a length of a joint Weld made by overlapping nuggets this type of welding is done on the fuel tanks and mudguards of scooter

5 Portable Spot Welding It is a portable gun which can be taken to specified range where other spot welding machine faces difficulty in welding This type of the welding is done on body covers of scooters

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 39

6 Fine Boring Fine boring is done on the frame where handle has to fit after fine boring handle is attached to it

When various operation of the welding on the different components of the scooter that is frame mudguard body covers and fuel tank is over then this welded body parts are loaded on to a conveyer hanger which takes these body parts to the weld body storage and in the weld body storage and in weld body storage there are three sections one for model 1 one for model 2 and the last for model 3 When welded body is loaded on to a conveyor then the person who loads these bodies on to the hanger select in which model hanger has to go and the selection is done with a selector switch present Up to 300 hangers can be stored in the storage area that means around 600 frames and 600 body covers can be stored in the weld storage area From storage area hangers move to the unloading area and from unloading area these body covers and frames are loaded on to a Carrier which takes them to the paint section Unloading of the frames and body covers depends on the requirement of the assembly line and which model they are making according to their requirement unloading of model frames and body covers is done Unloading of the model is again done by the selector switch that is when there is requirement of model 1 the person who unloads the frame presses model switch and from storage model 1 moves to the unloading area Similarly when there is requirement of model 2 then operator presses model 2 switch and same goes for the model 3 when the requirement is of model 3 the operator presses the model 3 switch and then from storage model 3 moves to unloading bay

Problem Analysis Of Carrier

Frame Hole NG

During the motion of the carrier when it is suddenly stopped by the stopper vibrations are produced in it and the pin inserted in the hole of the frame enlarges the size of the hole thereby causing the problem of frame hole NG

To reduce this problem an anti back-up system is applied to reduce the vibrations The NG frame hole is repaired by welding a bush at the site of the hole which is a newly developed Kaizen

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 64

Problems Caused By Loading

Improper loading of the frame body on the carrier damages the insulator collar because an unbalanced force acts upon it and insulator collars being the non-metallic parts are severely affected

R is the resultant vector

This is a production problem which causes the bending of jigs unbalancing of the carrier thereby causing improper motion at the carrier turns and revolutions and also resulting in the body parts falling in the oven

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 65

Gear Box Failure

Gear box of the carrier also fails some time due to overloading or improper coupling

Bending of Striker

Overloading at CTs and CRs causes the bending of the strikers which result in altered motion of the carrier

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 66

Breaking of Post

The post of the carrier can be broken due to variable and unbalanced load acting on the carrier The stresses are developed in the post which leads to its breaking Moreover hammering of the nut for the proper locking can also cause the breaking of nut

Overloading

Overloading is the state when the load on a part of the carrier is higher than its tolerance value Its causes are

If any object interrupts the motion of chain chain is not able to move forward properly causing overloading of chain

Improper position of the jig may lead to unbalancing of the carrier and overload may occur

Guide pin may not properly interact with the arm which may lead to non-alignment

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 67

Chain of the carrier turn may not be in proper position leading to overload at CT

Breaking of any of the carrier dogs will lead to improper revolution of the carrier

Other Problems

Cable breaks -gt Current does not reach to body part

ED COLLECTER burns out -gt It would not collect current

Threading of endndashplate striker wear out -gt Striker would not hit limit switch

Bush between coupling is cut

Bearing sometimes disrupts system

Swivel pipe bends -gt Carrier wouldnrsquot be leveled

Insulator sometimes fails to stop current

End plate threading wears

Spindle shaft bends -gt Carrier wouldnrsquot be leveled

Striker and arm also bends

8 Introduction to Maintenance Department

Introduction The maintenance department is one of the most important departments of the organization where the organization has its own production Maintenance department of Honda Motorcycle and Scooter India Private Limited (HMSI) is a responsible for all the breakdowns which occur in the machines or where there is any production loss so when to overcome the problem of production loss maintenance team has to work efficiently so that there is no mistake committed by them by which production loss occurs

Some important definitions used by maintenance

Maintenance Action necessary for retaining or restoring an equipment machine or system to the specified operable condition to achieve its maximum useful life It includes planned and preventive maintenance

Planned Maintenance Preventive maintenance carried out according to a fixed plan is called planned maintenance

Preventive Maintenance Systematic inspection detection correction and prevention of incipient failures before they become actual or major failures is called as preventive maintenance

Breakdown Maintenance Repair or replacements performed after a machine has failed to return to its functional state following a malfunction or shutdown is called as breakdown maintenance

Predictive Maintenance Type of preventive maintenance performed continuously or at interval according to the requirement to diagnose and

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 36

monitor a condition or system also called condition based maintenance is called as predictive maintenance

Mean Time To Repair (MTTR) Basic measure of maintainability of repairable items it represents the average mean time required to repair a failed component or device is defined as mean time to repair

Mean Time Between Failures (MTBF) Basic measure of the reliability of repairable items it represents the average number of a life units during which all parts of a device or system perform within their specified limits under specified conditions are called as mean time between failures

Down Time Period during which an equipment or machine is not functional or cannot work It may be due to technical failures mechanical adjustments maintenance or non availability of inputs such as materials labor and power etc is called as down time

Frame Maintenance In this department there are three sections

1 Press Section

2 Weld Section

Engine Maintenance Frame Maintenance

3 Paint Section

PRESS SECTION Press section has mainly four machines

Komatsu Pressndash3

AIDA Press -1

CNC bending machine

Hind Press

These presses are mechanical presses and on this press mudguard fuel tank nose and body cover of the scooters like activa aviator dio shine twister unicorn and twister Process like blanking coining and bending of pipes is done

Blanking is cutting up a large sheer of stock into smaller pieces suitable for next operation

Coining is the process of removal of extra material or to make work piece up to the limit All these mechanical presses are of 500 ton and there only one hydraulic press and this press are used to repair the dyes

CNC pipe bending machines are used to bend the pipes which later used in the manufacturing of the frame

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 38

WELDING SECTION In welding section there are six types of welding machines used in manufacturing of frames and body covers

1 Gantry System Gantry system is a system in which gantry crane is used for transporting the frame and welding is done by the robots and welding is finished by the robots the gantry crane picks up the frame and body covers and puts them on the conveyer or the hanger which goes to the weld body storage On gantry system seam welding is done on the body covers and on the frames with the help of the welding robots This system is fully automatic and there is no involvement of human being it picks up the frame and body covers from the location defined to it then does all the processing on it and then passes it to the conveyer

2 MIG Welding Metal inert gas welding in this inert gas argon is used and argon acts as a shielding gas 1-5 oxygen is used This type of welding uses consumable wire electrode during the welding process that is fed from the wire spool MIG welding has some advantages over the other welding techniques It provides a uniform weld it provides a slag free weld beam and needs little clean up

3 Spot Welding Spot welding is a process in which contacting metal surface are joined by the heat obtained from resistance to electric flow and this type of welding is done on the body covers of the scooter

4 Seam Welding It is a process that welds at a surface of overlapped parts along a length of a joint Weld made by overlapping nuggets this type of welding is done on the fuel tanks and mudguards of scooter

5 Portable Spot Welding It is a portable gun which can be taken to specified range where other spot welding machine faces difficulty in welding This type of the welding is done on body covers of scooters

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 39

6 Fine Boring Fine boring is done on the frame where handle has to fit after fine boring handle is attached to it

When various operation of the welding on the different components of the scooter that is frame mudguard body covers and fuel tank is over then this welded body parts are loaded on to a conveyer hanger which takes these body parts to the weld body storage and in the weld body storage and in weld body storage there are three sections one for model 1 one for model 2 and the last for model 3 When welded body is loaded on to a conveyor then the person who loads these bodies on to the hanger select in which model hanger has to go and the selection is done with a selector switch present Up to 300 hangers can be stored in the storage area that means around 600 frames and 600 body covers can be stored in the weld storage area From storage area hangers move to the unloading area and from unloading area these body covers and frames are loaded on to a Carrier which takes them to the paint section Unloading of the frames and body covers depends on the requirement of the assembly line and which model they are making according to their requirement unloading of model frames and body covers is done Unloading of the model is again done by the selector switch that is when there is requirement of model 1 the person who unloads the frame presses model switch and from storage model 1 moves to the unloading area Similarly when there is requirement of model 2 then operator presses model 2 switch and same goes for the model 3 when the requirement is of model 3 the operator presses the model 3 switch and then from storage model 3 moves to unloading bay

PAINT SECTION Paint section is very important section In this section different treatments are done on the body covers and frames and it is a step by step process done as follows

Loading

Pre-Treatment

Electro-Deposition

ED Oven

Booth

Top Coat Oven

Inspection Zone

Unloading

PAINT PROCESS FLOW

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 41

1 Sanding Zone

2 Under Coat

3 Top Coat

Loading In this process frames and body covers are mounted on the carrier of the conveyor line There are two lines for the paint that is paint A line and paint B line both the lines are very much important because in A line loading of frames and front body left right cover and rear body covers are loaded and on B line mudguard and front cowl is loaded and after loading of these parts then the carrier moves to the pretreatment zone

Pre-Treatment In pre-treatment degreasing and dust cleaning is done In pre-treatment bodies have to undergo two operations first wasting with the soft water by this process degreasing is done and all the dust particles are removed from the frames and body covers In general first we get hard water is converted to soft water by ion exchange mechanism

Secondly on bodies and frames phosphate cleaning is done by this method any dust particle or any grease particle left on the frames and body cover is removed

Electro-Deposition In electro deposition carrier which carries frame and body covers turn down into the electro deposition chamber and in electro deposition chamber is filled with the base paint or primer When carrier turns down it strikes high voltage wire and it gets negatively charged and become cathode and paint in the chamber becomes anode then a uniform thin film of base paint is deposited on

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 42

the body covers and frames of the scooter This process is repeated twice and after that it is passed to ED oven

ED Oven In electro deposition oven base coat done on the frame and body covers is heated to 150 degree temperature and this base coat is dried here and after that is passed to paint booth

Paint Booth Paint booth has three sections first one is sanding zone second primary coat or under coat and third is top coat

In sanding zone sanding of the frames and body covers is done and after that it is sent to under coat zone in under coat zone single coat of the paint is done on frames and body covers and in this zone coat of paint is done with the help of robots and after that frames and body covers then sent to top coat zone here in this zone second coat of the paint is done and this second coat of paint is done with the operator and after that these frames and body covers are sent to top coat oven

Top Coat Oven In top coat oven these frames and body covers are heated up to 170 degree temperature and dried and then allowed to cool naturally to room temperature and from there it is sent to the inspection zone

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 43

Inspection Zone In inspection zone body covers and frames have to pass infra-red zone Here IR testing machine checks for irregularities in the paint done and after that these body covers and frames are manually checked by hand for any errors in the paint jobs Parts which pass these tests get the OK mark and move to unloading area

Unloading In this area unloading of frames and body covers takes place Frames and body covers having OK mark are loaded to the paint body store and body covers and frames not having OK mark on them are sent to the repair work station and there they fix the problems which frames and body covers have They are then unloaded and then loaded on to the hanger and the parts go to the paint body storage In storage final or finished body covers and frames are stored which from storage area moves to the final assembly line

9 ProjectProject Definition

To study the various parts of the carrier being used in the paint shop and its problem analysis

Project Introduction

Carrier is defined as a thing which supports or holds up a part during its movement It is used to carry parts to the paint shop where various processes can be performed Carrier forms the basis of the Paint Shop because the movement of the parts from one point to another in the paint shop takes place only due to carrier The parts are loaded on the carrier with the help of a jig and then the motion takes place

Paint shop carrier is the most important moving part in the paint process Most problems and the breakdowns in the paint shop occur due to the carrier only It causes loss to the net production Bends or breaks due to load of body part applied on carrier causes distortions which ultimately results in the breakdown

Carrier is a part of the conveyer system being used in the paint shop The other components of the conveyer system are the prime mover drive (works as the input motion source for chain) chain and chain track carrier carrier turn (for turning the carrier) carrier

Problem Analysis Of Carrier

Frame Hole NG

During the motion of the carrier when it is suddenly stopped by the stopper vibrations are produced in it and the pin inserted in the hole of the frame enlarges the size of the hole thereby causing the problem of frame hole NG

To reduce this problem an anti back-up system is applied to reduce the vibrations The NG frame hole is repaired by welding a bush at the site of the hole which is a newly developed Kaizen

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 64

Problems Caused By Loading

Improper loading of the frame body on the carrier damages the insulator collar because an unbalanced force acts upon it and insulator collars being the non-metallic parts are severely affected

R is the resultant vector

This is a production problem which causes the bending of jigs unbalancing of the carrier thereby causing improper motion at the carrier turns and revolutions and also resulting in the body parts falling in the oven

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 65

Gear Box Failure

Gear box of the carrier also fails some time due to overloading or improper coupling

Bending of Striker

Overloading at CTs and CRs causes the bending of the strikers which result in altered motion of the carrier

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 66

Breaking of Post

The post of the carrier can be broken due to variable and unbalanced load acting on the carrier The stresses are developed in the post which leads to its breaking Moreover hammering of the nut for the proper locking can also cause the breaking of nut

Overloading

Overloading is the state when the load on a part of the carrier is higher than its tolerance value Its causes are

If any object interrupts the motion of chain chain is not able to move forward properly causing overloading of chain

Improper position of the jig may lead to unbalancing of the carrier and overload may occur

Guide pin may not properly interact with the arm which may lead to non-alignment

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 67

Chain of the carrier turn may not be in proper position leading to overload at CT

Breaking of any of the carrier dogs will lead to improper revolution of the carrier

Other Problems

Cable breaks -gt Current does not reach to body part

ED COLLECTER burns out -gt It would not collect current

Threading of endndashplate striker wear out -gt Striker would not hit limit switch

Bush between coupling is cut

Bearing sometimes disrupts system

Swivel pipe bends -gt Carrier wouldnrsquot be leveled

Insulator sometimes fails to stop current

End plate threading wears

Spindle shaft bends -gt Carrier wouldnrsquot be leveled

Striker and arm also bends

8 Introduction to Maintenance Department

Introduction The maintenance department is one of the most important departments of the organization where the organization has its own production Maintenance department of Honda Motorcycle and Scooter India Private Limited (HMSI) is a responsible for all the breakdowns which occur in the machines or where there is any production loss so when to overcome the problem of production loss maintenance team has to work efficiently so that there is no mistake committed by them by which production loss occurs

Some important definitions used by maintenance

Maintenance Action necessary for retaining or restoring an equipment machine or system to the specified operable condition to achieve its maximum useful life It includes planned and preventive maintenance

Planned Maintenance Preventive maintenance carried out according to a fixed plan is called planned maintenance

Preventive Maintenance Systematic inspection detection correction and prevention of incipient failures before they become actual or major failures is called as preventive maintenance

Breakdown Maintenance Repair or replacements performed after a machine has failed to return to its functional state following a malfunction or shutdown is called as breakdown maintenance

Predictive Maintenance Type of preventive maintenance performed continuously or at interval according to the requirement to diagnose and

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 36

monitor a condition or system also called condition based maintenance is called as predictive maintenance

Mean Time To Repair (MTTR) Basic measure of maintainability of repairable items it represents the average mean time required to repair a failed component or device is defined as mean time to repair

Mean Time Between Failures (MTBF) Basic measure of the reliability of repairable items it represents the average number of a life units during which all parts of a device or system perform within their specified limits under specified conditions are called as mean time between failures

Down Time Period during which an equipment or machine is not functional or cannot work It may be due to technical failures mechanical adjustments maintenance or non availability of inputs such as materials labor and power etc is called as down time

Frame Maintenance In this department there are three sections

1 Press Section

2 Weld Section

Engine Maintenance Frame Maintenance

3 Paint Section

PRESS SECTION Press section has mainly four machines

Komatsu Pressndash3

AIDA Press -1

CNC bending machine

Hind Press

These presses are mechanical presses and on this press mudguard fuel tank nose and body cover of the scooters like activa aviator dio shine twister unicorn and twister Process like blanking coining and bending of pipes is done

Blanking is cutting up a large sheer of stock into smaller pieces suitable for next operation

Coining is the process of removal of extra material or to make work piece up to the limit All these mechanical presses are of 500 ton and there only one hydraulic press and this press are used to repair the dyes

CNC pipe bending machines are used to bend the pipes which later used in the manufacturing of the frame

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 38

WELDING SECTION In welding section there are six types of welding machines used in manufacturing of frames and body covers

1 Gantry System Gantry system is a system in which gantry crane is used for transporting the frame and welding is done by the robots and welding is finished by the robots the gantry crane picks up the frame and body covers and puts them on the conveyer or the hanger which goes to the weld body storage On gantry system seam welding is done on the body covers and on the frames with the help of the welding robots This system is fully automatic and there is no involvement of human being it picks up the frame and body covers from the location defined to it then does all the processing on it and then passes it to the conveyer

2 MIG Welding Metal inert gas welding in this inert gas argon is used and argon acts as a shielding gas 1-5 oxygen is used This type of welding uses consumable wire electrode during the welding process that is fed from the wire spool MIG welding has some advantages over the other welding techniques It provides a uniform weld it provides a slag free weld beam and needs little clean up

3 Spot Welding Spot welding is a process in which contacting metal surface are joined by the heat obtained from resistance to electric flow and this type of welding is done on the body covers of the scooter

4 Seam Welding It is a process that welds at a surface of overlapped parts along a length of a joint Weld made by overlapping nuggets this type of welding is done on the fuel tanks and mudguards of scooter

5 Portable Spot Welding It is a portable gun which can be taken to specified range where other spot welding machine faces difficulty in welding This type of the welding is done on body covers of scooters

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 39

6 Fine Boring Fine boring is done on the frame where handle has to fit after fine boring handle is attached to it

When various operation of the welding on the different components of the scooter that is frame mudguard body covers and fuel tank is over then this welded body parts are loaded on to a conveyer hanger which takes these body parts to the weld body storage and in the weld body storage and in weld body storage there are three sections one for model 1 one for model 2 and the last for model 3 When welded body is loaded on to a conveyor then the person who loads these bodies on to the hanger select in which model hanger has to go and the selection is done with a selector switch present Up to 300 hangers can be stored in the storage area that means around 600 frames and 600 body covers can be stored in the weld storage area From storage area hangers move to the unloading area and from unloading area these body covers and frames are loaded on to a Carrier which takes them to the paint section Unloading of the frames and body covers depends on the requirement of the assembly line and which model they are making according to their requirement unloading of model frames and body covers is done Unloading of the model is again done by the selector switch that is when there is requirement of model 1 the person who unloads the frame presses model switch and from storage model 1 moves to the unloading area Similarly when there is requirement of model 2 then operator presses model 2 switch and same goes for the model 3 when the requirement is of model 3 the operator presses the model 3 switch and then from storage model 3 moves to unloading bay

PAINT SECTION Paint section is very important section In this section different treatments are done on the body covers and frames and it is a step by step process done as follows

Loading

Pre-Treatment

Electro-Deposition

ED Oven

Booth

Top Coat Oven

Inspection Zone

Unloading

PAINT PROCESS FLOW

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 41

1 Sanding Zone

2 Under Coat

3 Top Coat

Loading In this process frames and body covers are mounted on the carrier of the conveyor line There are two lines for the paint that is paint A line and paint B line both the lines are very much important because in A line loading of frames and front body left right cover and rear body covers are loaded and on B line mudguard and front cowl is loaded and after loading of these parts then the carrier moves to the pretreatment zone

Pre-Treatment In pre-treatment degreasing and dust cleaning is done In pre-treatment bodies have to undergo two operations first wasting with the soft water by this process degreasing is done and all the dust particles are removed from the frames and body covers In general first we get hard water is converted to soft water by ion exchange mechanism

Secondly on bodies and frames phosphate cleaning is done by this method any dust particle or any grease particle left on the frames and body cover is removed

Electro-Deposition In electro deposition carrier which carries frame and body covers turn down into the electro deposition chamber and in electro deposition chamber is filled with the base paint or primer When carrier turns down it strikes high voltage wire and it gets negatively charged and become cathode and paint in the chamber becomes anode then a uniform thin film of base paint is deposited on

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 42

the body covers and frames of the scooter This process is repeated twice and after that it is passed to ED oven

ED Oven In electro deposition oven base coat done on the frame and body covers is heated to 150 degree temperature and this base coat is dried here and after that is passed to paint booth

Paint Booth Paint booth has three sections first one is sanding zone second primary coat or under coat and third is top coat

In sanding zone sanding of the frames and body covers is done and after that it is sent to under coat zone in under coat zone single coat of the paint is done on frames and body covers and in this zone coat of paint is done with the help of robots and after that frames and body covers then sent to top coat zone here in this zone second coat of the paint is done and this second coat of paint is done with the operator and after that these frames and body covers are sent to top coat oven

Top Coat Oven In top coat oven these frames and body covers are heated up to 170 degree temperature and dried and then allowed to cool naturally to room temperature and from there it is sent to the inspection zone

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 43

Inspection Zone In inspection zone body covers and frames have to pass infra-red zone Here IR testing machine checks for irregularities in the paint done and after that these body covers and frames are manually checked by hand for any errors in the paint jobs Parts which pass these tests get the OK mark and move to unloading area

Unloading In this area unloading of frames and body covers takes place Frames and body covers having OK mark are loaded to the paint body store and body covers and frames not having OK mark on them are sent to the repair work station and there they fix the problems which frames and body covers have They are then unloaded and then loaded on to the hanger and the parts go to the paint body storage In storage final or finished body covers and frames are stored which from storage area moves to the final assembly line

9 ProjectProject Definition

To study the various parts of the carrier being used in the paint shop and its problem analysis

Project Introduction

Carrier is defined as a thing which supports or holds up a part during its movement It is used to carry parts to the paint shop where various processes can be performed Carrier forms the basis of the Paint Shop because the movement of the parts from one point to another in the paint shop takes place only due to carrier The parts are loaded on the carrier with the help of a jig and then the motion takes place

Paint shop carrier is the most important moving part in the paint process Most problems and the breakdowns in the paint shop occur due to the carrier only It causes loss to the net production Bends or breaks due to load of body part applied on carrier causes distortions which ultimately results in the breakdown

Carrier is a part of the conveyer system being used in the paint shop The other components of the conveyer system are the prime mover drive (works as the input motion source for chain) chain and chain track carrier carrier turn (for turning the carrier) carrier

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 45

revolution (for revolving the carrier) stopper (it temporarily stops the carrier on line) carrier locks auto feeder cylinders and drop lifters which support the motion of carrier

Part Description Of Carrier

Rail

Rail can be of two types ie pre rail and power rail Pre rail is used to drive trolley of the carrier Power rail is used to drive the conveyer system

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 46

Gear Box

Gear Box acts as a Speed Reducer It consists of a worm and worm-wheel arrangement which turns the axis of rotation by 90deg and reduces the speed of the parts The gear box is coupled with the small sprocket Gear transmits power to small sprocket which helps for carrier turn this is also called as reduction gear The relation between the torque and diameter of worm shaft is given by

T (Kg-m) = π16dsup3τ

where τ is the twisting moment

Velocity Ratio = 160

Tensile Strength of Material = 60 Kgmmsup2

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 47

Trolley

Problem Analysis Of Carrier

Frame Hole NG

During the motion of the carrier when it is suddenly stopped by the stopper vibrations are produced in it and the pin inserted in the hole of the frame enlarges the size of the hole thereby causing the problem of frame hole NG

To reduce this problem an anti back-up system is applied to reduce the vibrations The NG frame hole is repaired by welding a bush at the site of the hole which is a newly developed Kaizen

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 64

Problems Caused By Loading

Improper loading of the frame body on the carrier damages the insulator collar because an unbalanced force acts upon it and insulator collars being the non-metallic parts are severely affected

R is the resultant vector

This is a production problem which causes the bending of jigs unbalancing of the carrier thereby causing improper motion at the carrier turns and revolutions and also resulting in the body parts falling in the oven

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 65

Gear Box Failure

Gear box of the carrier also fails some time due to overloading or improper coupling

Bending of Striker

Overloading at CTs and CRs causes the bending of the strikers which result in altered motion of the carrier

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 66

Breaking of Post

The post of the carrier can be broken due to variable and unbalanced load acting on the carrier The stresses are developed in the post which leads to its breaking Moreover hammering of the nut for the proper locking can also cause the breaking of nut

Overloading

Overloading is the state when the load on a part of the carrier is higher than its tolerance value Its causes are

If any object interrupts the motion of chain chain is not able to move forward properly causing overloading of chain

Improper position of the jig may lead to unbalancing of the carrier and overload may occur

Guide pin may not properly interact with the arm which may lead to non-alignment

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 67

Chain of the carrier turn may not be in proper position leading to overload at CT

Breaking of any of the carrier dogs will lead to improper revolution of the carrier

Other Problems

Cable breaks -gt Current does not reach to body part

ED COLLECTER burns out -gt It would not collect current

Threading of endndashplate striker wear out -gt Striker would not hit limit switch

Bush between coupling is cut

Bearing sometimes disrupts system

Swivel pipe bends -gt Carrier wouldnrsquot be leveled

Insulator sometimes fails to stop current

End plate threading wears

Spindle shaft bends -gt Carrier wouldnrsquot be leveled

Striker and arm also bends

8 Introduction to Maintenance Department

Introduction The maintenance department is one of the most important departments of the organization where the organization has its own production Maintenance department of Honda Motorcycle and Scooter India Private Limited (HMSI) is a responsible for all the breakdowns which occur in the machines or where there is any production loss so when to overcome the problem of production loss maintenance team has to work efficiently so that there is no mistake committed by them by which production loss occurs

Some important definitions used by maintenance

Maintenance Action necessary for retaining or restoring an equipment machine or system to the specified operable condition to achieve its maximum useful life It includes planned and preventive maintenance

Planned Maintenance Preventive maintenance carried out according to a fixed plan is called planned maintenance

Preventive Maintenance Systematic inspection detection correction and prevention of incipient failures before they become actual or major failures is called as preventive maintenance

Breakdown Maintenance Repair or replacements performed after a machine has failed to return to its functional state following a malfunction or shutdown is called as breakdown maintenance

Predictive Maintenance Type of preventive maintenance performed continuously or at interval according to the requirement to diagnose and

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 36

monitor a condition or system also called condition based maintenance is called as predictive maintenance

Mean Time To Repair (MTTR) Basic measure of maintainability of repairable items it represents the average mean time required to repair a failed component or device is defined as mean time to repair

Mean Time Between Failures (MTBF) Basic measure of the reliability of repairable items it represents the average number of a life units during which all parts of a device or system perform within their specified limits under specified conditions are called as mean time between failures

Down Time Period during which an equipment or machine is not functional or cannot work It may be due to technical failures mechanical adjustments maintenance or non availability of inputs such as materials labor and power etc is called as down time

Frame Maintenance In this department there are three sections

1 Press Section

2 Weld Section

Engine Maintenance Frame Maintenance

3 Paint Section

PRESS SECTION Press section has mainly four machines

Komatsu Pressndash3

AIDA Press -1

CNC bending machine

Hind Press

These presses are mechanical presses and on this press mudguard fuel tank nose and body cover of the scooters like activa aviator dio shine twister unicorn and twister Process like blanking coining and bending of pipes is done

Blanking is cutting up a large sheer of stock into smaller pieces suitable for next operation

Coining is the process of removal of extra material or to make work piece up to the limit All these mechanical presses are of 500 ton and there only one hydraulic press and this press are used to repair the dyes

CNC pipe bending machines are used to bend the pipes which later used in the manufacturing of the frame

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 38

WELDING SECTION In welding section there are six types of welding machines used in manufacturing of frames and body covers

1 Gantry System Gantry system is a system in which gantry crane is used for transporting the frame and welding is done by the robots and welding is finished by the robots the gantry crane picks up the frame and body covers and puts them on the conveyer or the hanger which goes to the weld body storage On gantry system seam welding is done on the body covers and on the frames with the help of the welding robots This system is fully automatic and there is no involvement of human being it picks up the frame and body covers from the location defined to it then does all the processing on it and then passes it to the conveyer

2 MIG Welding Metal inert gas welding in this inert gas argon is used and argon acts as a shielding gas 1-5 oxygen is used This type of welding uses consumable wire electrode during the welding process that is fed from the wire spool MIG welding has some advantages over the other welding techniques It provides a uniform weld it provides a slag free weld beam and needs little clean up

3 Spot Welding Spot welding is a process in which contacting metal surface are joined by the heat obtained from resistance to electric flow and this type of welding is done on the body covers of the scooter

4 Seam Welding It is a process that welds at a surface of overlapped parts along a length of a joint Weld made by overlapping nuggets this type of welding is done on the fuel tanks and mudguards of scooter

5 Portable Spot Welding It is a portable gun which can be taken to specified range where other spot welding machine faces difficulty in welding This type of the welding is done on body covers of scooters

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 39

6 Fine Boring Fine boring is done on the frame where handle has to fit after fine boring handle is attached to it

When various operation of the welding on the different components of the scooter that is frame mudguard body covers and fuel tank is over then this welded body parts are loaded on to a conveyer hanger which takes these body parts to the weld body storage and in the weld body storage and in weld body storage there are three sections one for model 1 one for model 2 and the last for model 3 When welded body is loaded on to a conveyor then the person who loads these bodies on to the hanger select in which model hanger has to go and the selection is done with a selector switch present Up to 300 hangers can be stored in the storage area that means around 600 frames and 600 body covers can be stored in the weld storage area From storage area hangers move to the unloading area and from unloading area these body covers and frames are loaded on to a Carrier which takes them to the paint section Unloading of the frames and body covers depends on the requirement of the assembly line and which model they are making according to their requirement unloading of model frames and body covers is done Unloading of the model is again done by the selector switch that is when there is requirement of model 1 the person who unloads the frame presses model switch and from storage model 1 moves to the unloading area Similarly when there is requirement of model 2 then operator presses model 2 switch and same goes for the model 3 when the requirement is of model 3 the operator presses the model 3 switch and then from storage model 3 moves to unloading bay

PAINT SECTION Paint section is very important section In this section different treatments are done on the body covers and frames and it is a step by step process done as follows

Loading

Pre-Treatment

Electro-Deposition

ED Oven

Booth

Top Coat Oven

Inspection Zone

Unloading

PAINT PROCESS FLOW

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 41

1 Sanding Zone

2 Under Coat

3 Top Coat

Loading In this process frames and body covers are mounted on the carrier of the conveyor line There are two lines for the paint that is paint A line and paint B line both the lines are very much important because in A line loading of frames and front body left right cover and rear body covers are loaded and on B line mudguard and front cowl is loaded and after loading of these parts then the carrier moves to the pretreatment zone

Pre-Treatment In pre-treatment degreasing and dust cleaning is done In pre-treatment bodies have to undergo two operations first wasting with the soft water by this process degreasing is done and all the dust particles are removed from the frames and body covers In general first we get hard water is converted to soft water by ion exchange mechanism

Secondly on bodies and frames phosphate cleaning is done by this method any dust particle or any grease particle left on the frames and body cover is removed

Electro-Deposition In electro deposition carrier which carries frame and body covers turn down into the electro deposition chamber and in electro deposition chamber is filled with the base paint or primer When carrier turns down it strikes high voltage wire and it gets negatively charged and become cathode and paint in the chamber becomes anode then a uniform thin film of base paint is deposited on

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 42

the body covers and frames of the scooter This process is repeated twice and after that it is passed to ED oven

ED Oven In electro deposition oven base coat done on the frame and body covers is heated to 150 degree temperature and this base coat is dried here and after that is passed to paint booth

Paint Booth Paint booth has three sections first one is sanding zone second primary coat or under coat and third is top coat

In sanding zone sanding of the frames and body covers is done and after that it is sent to under coat zone in under coat zone single coat of the paint is done on frames and body covers and in this zone coat of paint is done with the help of robots and after that frames and body covers then sent to top coat zone here in this zone second coat of the paint is done and this second coat of paint is done with the operator and after that these frames and body covers are sent to top coat oven

Top Coat Oven In top coat oven these frames and body covers are heated up to 170 degree temperature and dried and then allowed to cool naturally to room temperature and from there it is sent to the inspection zone

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 43

Inspection Zone In inspection zone body covers and frames have to pass infra-red zone Here IR testing machine checks for irregularities in the paint done and after that these body covers and frames are manually checked by hand for any errors in the paint jobs Parts which pass these tests get the OK mark and move to unloading area

Unloading In this area unloading of frames and body covers takes place Frames and body covers having OK mark are loaded to the paint body store and body covers and frames not having OK mark on them are sent to the repair work station and there they fix the problems which frames and body covers have They are then unloaded and then loaded on to the hanger and the parts go to the paint body storage In storage final or finished body covers and frames are stored which from storage area moves to the final assembly line

9 ProjectProject Definition

To study the various parts of the carrier being used in the paint shop and its problem analysis

Project Introduction

Carrier is defined as a thing which supports or holds up a part during its movement It is used to carry parts to the paint shop where various processes can be performed Carrier forms the basis of the Paint Shop because the movement of the parts from one point to another in the paint shop takes place only due to carrier The parts are loaded on the carrier with the help of a jig and then the motion takes place

Paint shop carrier is the most important moving part in the paint process Most problems and the breakdowns in the paint shop occur due to the carrier only It causes loss to the net production Bends or breaks due to load of body part applied on carrier causes distortions which ultimately results in the breakdown

Carrier is a part of the conveyer system being used in the paint shop The other components of the conveyer system are the prime mover drive (works as the input motion source for chain) chain and chain track carrier carrier turn (for turning the carrier) carrier

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 45

revolution (for revolving the carrier) stopper (it temporarily stops the carrier on line) carrier locks auto feeder cylinders and drop lifters which support the motion of carrier

Part Description Of Carrier

Rail

Rail can be of two types ie pre rail and power rail Pre rail is used to drive trolley of the carrier Power rail is used to drive the conveyer system

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 46

Gear Box

Gear Box acts as a Speed Reducer It consists of a worm and worm-wheel arrangement which turns the axis of rotation by 90deg and reduces the speed of the parts The gear box is coupled with the small sprocket Gear transmits power to small sprocket which helps for carrier turn this is also called as reduction gear The relation between the torque and diameter of worm shaft is given by

T (Kg-m) = π16dsup3τ

where τ is the twisting moment

Velocity Ratio = 160

Tensile Strength of Material = 60 Kgmmsup2

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 47

Trolley

There are two trolleys present in a carrier namely Front and the Rear Trolley Front Trolley stops the carrier at a specified position by the actuation of stopper while Rear Trolley stops the next carrier by engaging with the Front trolley of next carrier Trolley Wheel contains ball bearings The outer race serves as a wheel A grease fitting is installed as a greasing port Guide Roller is installed to reduce friction against free rail Pivoting Dog is lifted by the own weight The chain pusher engages to the Pivoting dog for transport To stop the carrier the stopper (installed on the line) pushes down the Pivoting Dog to release the engagement with the pusher

Problem Analysis Of Carrier

Frame Hole NG

During the motion of the carrier when it is suddenly stopped by the stopper vibrations are produced in it and the pin inserted in the hole of the frame enlarges the size of the hole thereby causing the problem of frame hole NG

To reduce this problem an anti back-up system is applied to reduce the vibrations The NG frame hole is repaired by welding a bush at the site of the hole which is a newly developed Kaizen

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 64

Problems Caused By Loading

Improper loading of the frame body on the carrier damages the insulator collar because an unbalanced force acts upon it and insulator collars being the non-metallic parts are severely affected

R is the resultant vector

This is a production problem which causes the bending of jigs unbalancing of the carrier thereby causing improper motion at the carrier turns and revolutions and also resulting in the body parts falling in the oven

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 65

Gear Box Failure

Gear box of the carrier also fails some time due to overloading or improper coupling

Bending of Striker

Overloading at CTs and CRs causes the bending of the strikers which result in altered motion of the carrier

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 66

Breaking of Post

The post of the carrier can be broken due to variable and unbalanced load acting on the carrier The stresses are developed in the post which leads to its breaking Moreover hammering of the nut for the proper locking can also cause the breaking of nut

Overloading

Overloading is the state when the load on a part of the carrier is higher than its tolerance value Its causes are

If any object interrupts the motion of chain chain is not able to move forward properly causing overloading of chain

Improper position of the jig may lead to unbalancing of the carrier and overload may occur

Guide pin may not properly interact with the arm which may lead to non-alignment

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 67

Chain of the carrier turn may not be in proper position leading to overload at CT

Breaking of any of the carrier dogs will lead to improper revolution of the carrier

Other Problems

Cable breaks -gt Current does not reach to body part

ED COLLECTER burns out -gt It would not collect current

Threading of endndashplate striker wear out -gt Striker would not hit limit switch

Bush between coupling is cut

Bearing sometimes disrupts system

Swivel pipe bends -gt Carrier wouldnrsquot be leveled

Insulator sometimes fails to stop current

End plate threading wears

Spindle shaft bends -gt Carrier wouldnrsquot be leveled

Striker and arm also bends

8 Introduction to Maintenance Department

Introduction The maintenance department is one of the most important departments of the organization where the organization has its own production Maintenance department of Honda Motorcycle and Scooter India Private Limited (HMSI) is a responsible for all the breakdowns which occur in the machines or where there is any production loss so when to overcome the problem of production loss maintenance team has to work efficiently so that there is no mistake committed by them by which production loss occurs

Some important definitions used by maintenance

Maintenance Action necessary for retaining or restoring an equipment machine or system to the specified operable condition to achieve its maximum useful life It includes planned and preventive maintenance

Planned Maintenance Preventive maintenance carried out according to a fixed plan is called planned maintenance

Preventive Maintenance Systematic inspection detection correction and prevention of incipient failures before they become actual or major failures is called as preventive maintenance

Breakdown Maintenance Repair or replacements performed after a machine has failed to return to its functional state following a malfunction or shutdown is called as breakdown maintenance

Predictive Maintenance Type of preventive maintenance performed continuously or at interval according to the requirement to diagnose and

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 36

monitor a condition or system also called condition based maintenance is called as predictive maintenance

Mean Time To Repair (MTTR) Basic measure of maintainability of repairable items it represents the average mean time required to repair a failed component or device is defined as mean time to repair

Mean Time Between Failures (MTBF) Basic measure of the reliability of repairable items it represents the average number of a life units during which all parts of a device or system perform within their specified limits under specified conditions are called as mean time between failures

Down Time Period during which an equipment or machine is not functional or cannot work It may be due to technical failures mechanical adjustments maintenance or non availability of inputs such as materials labor and power etc is called as down time

Frame Maintenance In this department there are three sections

1 Press Section

2 Weld Section

3 Paint Section

PRESS SECTION Press section has mainly four machines

Komatsu Pressndash3

AIDA Press -1

CNC bending machine

Hind Press

These presses are mechanical presses and on this press mudguard fuel tank nose and body cover of the scooters like activa aviator dio shine twister unicorn and twister Process like blanking coining and bending of pipes is done

Blanking is cutting up a large sheer of stock into smaller pieces suitable for next operation

Coining is the process of removal of extra material or to make work piece up to the limit All these mechanical presses are of 500 ton and there only one hydraulic press and this press are used to repair the dyes

CNC pipe bending machines are used to bend the pipes which later used in the manufacturing of the frame

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 38

WELDING SECTION In welding section there are six types of welding machines used in manufacturing of frames and body covers

1 Gantry System Gantry system is a system in which gantry crane is used for transporting the frame and welding is done by the robots and welding is finished by the robots the gantry crane picks up the frame and body covers and puts them on the conveyer or the hanger which goes to the weld body storage On gantry system seam welding is done on the body covers and on the frames with the help of the welding robots This system is fully automatic and there is no involvement of human being it picks up the frame and body covers from the location defined to it then does all the processing on it and then passes it to the conveyer

2 MIG Welding Metal inert gas welding in this inert gas argon is used and argon acts as a shielding gas 1-5 oxygen is used This type of welding uses consumable wire electrode during the welding process that is fed from the wire spool MIG welding has some advantages over the other welding techniques It provides a uniform weld it provides a slag free weld beam and needs little clean up

3 Spot Welding Spot welding is a process in which contacting metal surface are joined by the heat obtained from resistance to electric flow and this type of welding is done on the body covers of the scooter

4 Seam Welding It is a process that welds at a surface of overlapped parts along a length of a joint Weld made by overlapping nuggets this type of welding is done on the fuel tanks and mudguards of scooter

5 Portable Spot Welding It is a portable gun which can be taken to specified range where other spot welding machine faces difficulty in welding This type of the welding is done on body covers of scooters

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 39

6 Fine Boring Fine boring is done on the frame where handle has to fit after fine boring handle is attached to it

When various operation of the welding on the different components of the scooter that is frame mudguard body covers and fuel tank is over then this welded body parts are loaded on to a conveyer hanger which takes these body parts to the weld body storage and in the weld body storage and in weld body storage there are three sections one for model 1 one for model 2 and the last for model 3 When welded body is loaded on to a conveyor then the person who loads these bodies on to the hanger select in which model hanger has to go and the selection is done with a selector switch present Up to 300 hangers can be stored in the storage area that means around 600 frames and 600 body covers can be stored in the weld storage area From storage area hangers move to the unloading area and from unloading area these body covers and frames are loaded on to a Carrier which takes them to the paint section Unloading of the frames and body covers depends on the requirement of the assembly line and which model they are making according to their requirement unloading of model frames and body covers is done Unloading of the model is again done by the selector switch that is when there is requirement of model 1 the person who unloads the frame presses model switch and from storage model 1 moves to the unloading area Similarly when there is requirement of model 2 then operator presses model 2 switch and same goes for the model 3 when the requirement is of model 3 the operator presses the model 3 switch and then from storage model 3 moves to unloading bay

PAINT SECTION Paint section is very important section In this section different treatments are done on the body covers and frames and it is a step by step process done as follows

Loading

Pre-Treatment

Electro-Deposition

ED Oven

Booth

Top Coat Oven

Inspection Zone

Unloading

PAINT PROCESS FLOW

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 41

1 Sanding Zone

2 Under Coat

3 Top Coat

Loading In this process frames and body covers are mounted on the carrier of the conveyor line There are two lines for the paint that is paint A line and paint B line both the lines are very much important because in A line loading of frames and front body left right cover and rear body covers are loaded and on B line mudguard and front cowl is loaded and after loading of these parts then the carrier moves to the pretreatment zone

Pre-Treatment In pre-treatment degreasing and dust cleaning is done In pre-treatment bodies have to undergo two operations first wasting with the soft water by this process degreasing is done and all the dust particles are removed from the frames and body covers In general first we get hard water is converted to soft water by ion exchange mechanism

Secondly on bodies and frames phosphate cleaning is done by this method any dust particle or any grease particle left on the frames and body cover is removed

Electro-Deposition In electro deposition carrier which carries frame and body covers turn down into the electro deposition chamber and in electro deposition chamber is filled with the base paint or primer When carrier turns down it strikes high voltage wire and it gets negatively charged and become cathode and paint in the chamber becomes anode then a uniform thin film of base paint is deposited on

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 42

the body covers and frames of the scooter This process is repeated twice and after that it is passed to ED oven

ED Oven In electro deposition oven base coat done on the frame and body covers is heated to 150 degree temperature and this base coat is dried here and after that is passed to paint booth

Paint Booth Paint booth has three sections first one is sanding zone second primary coat or under coat and third is top coat

In sanding zone sanding of the frames and body covers is done and after that it is sent to under coat zone in under coat zone single coat of the paint is done on frames and body covers and in this zone coat of paint is done with the help of robots and after that frames and body covers then sent to top coat zone here in this zone second coat of the paint is done and this second coat of paint is done with the operator and after that these frames and body covers are sent to top coat oven

Top Coat Oven In top coat oven these frames and body covers are heated up to 170 degree temperature and dried and then allowed to cool naturally to room temperature and from there it is sent to the inspection zone

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 43

Inspection Zone In inspection zone body covers and frames have to pass infra-red zone Here IR testing machine checks for irregularities in the paint done and after that these body covers and frames are manually checked by hand for any errors in the paint jobs Parts which pass these tests get the OK mark and move to unloading area

Unloading In this area unloading of frames and body covers takes place Frames and body covers having OK mark are loaded to the paint body store and body covers and frames not having OK mark on them are sent to the repair work station and there they fix the problems which frames and body covers have They are then unloaded and then loaded on to the hanger and the parts go to the paint body storage In storage final or finished body covers and frames are stored which from storage area moves to the final assembly line

9 ProjectProject Definition

To study the various parts of the carrier being used in the paint shop and its problem analysis

Project Introduction

Carrier is defined as a thing which supports or holds up a part during its movement It is used to carry parts to the paint shop where various processes can be performed Carrier forms the basis of the Paint Shop because the movement of the parts from one point to another in the paint shop takes place only due to carrier The parts are loaded on the carrier with the help of a jig and then the motion takes place

Paint shop carrier is the most important moving part in the paint process Most problems and the breakdowns in the paint shop occur due to the carrier only It causes loss to the net production Bends or breaks due to load of body part applied on carrier causes distortions which ultimately results in the breakdown

Carrier is a part of the conveyer system being used in the paint shop The other components of the conveyer system are the prime mover drive (works as the input motion source for chain) chain and chain track carrier carrier turn (for turning the carrier) carrier

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 45

revolution (for revolving the carrier) stopper (it temporarily stops the carrier on line) carrier locks auto feeder cylinders and drop lifters which support the motion of carrier

Part Description Of Carrier

Rail

Rail can be of two types ie pre rail and power rail Pre rail is used to drive trolley of the carrier Power rail is used to drive the conveyer system

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 46

Gear Box

Gear Box acts as a Speed Reducer It consists of a worm and worm-wheel arrangement which turns the axis of rotation by 90deg and reduces the speed of the parts The gear box is coupled with the small sprocket Gear transmits power to small sprocket which helps for carrier turn this is also called as reduction gear The relation between the torque and diameter of worm shaft is given by

T (Kg-m) = π16dsup3τ

where τ is the twisting moment

Velocity Ratio = 160

Tensile Strength of Material = 60 Kgmmsup2

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 47

Trolley

Problem Analysis Of Carrier

Frame Hole NG

During the motion of the carrier when it is suddenly stopped by the stopper vibrations are produced in it and the pin inserted in the hole of the frame enlarges the size of the hole thereby causing the problem of frame hole NG

To reduce this problem an anti back-up system is applied to reduce the vibrations The NG frame hole is repaired by welding a bush at the site of the hole which is a newly developed Kaizen

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 64

Problems Caused By Loading

Improper loading of the frame body on the carrier damages the insulator collar because an unbalanced force acts upon it and insulator collars being the non-metallic parts are severely affected

R is the resultant vector

This is a production problem which causes the bending of jigs unbalancing of the carrier thereby causing improper motion at the carrier turns and revolutions and also resulting in the body parts falling in the oven

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 65

Gear Box Failure

Gear box of the carrier also fails some time due to overloading or improper coupling

Bending of Striker

Overloading at CTs and CRs causes the bending of the strikers which result in altered motion of the carrier

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 66

Breaking of Post

The post of the carrier can be broken due to variable and unbalanced load acting on the carrier The stresses are developed in the post which leads to its breaking Moreover hammering of the nut for the proper locking can also cause the breaking of nut

Overloading

Overloading is the state when the load on a part of the carrier is higher than its tolerance value Its causes are

If any object interrupts the motion of chain chain is not able to move forward properly causing overloading of chain

Improper position of the jig may lead to unbalancing of the carrier and overload may occur

Guide pin may not properly interact with the arm which may lead to non-alignment

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 67

Chain of the carrier turn may not be in proper position leading to overload at CT

Breaking of any of the carrier dogs will lead to improper revolution of the carrier

Other Problems

Cable breaks -gt Current does not reach to body part

ED COLLECTER burns out -gt It would not collect current

Threading of endndashplate striker wear out -gt Striker would not hit limit switch

Bush between coupling is cut

Bearing sometimes disrupts system

Swivel pipe bends -gt Carrier wouldnrsquot be leveled

Insulator sometimes fails to stop current

End plate threading wears

Spindle shaft bends -gt Carrier wouldnrsquot be leveled

Striker and arm also bends

the body covers and frames of the scooter This process is repeated twice and after that it is passed to ED oven

ED Oven In electro deposition oven base coat done on the frame and body covers is heated to 150 degree temperature and this base coat is dried here and after that is passed to paint booth

Paint Booth Paint booth has three sections first one is sanding zone second primary coat or under coat and third is top coat

In sanding zone sanding of the frames and body covers is done and after that it is sent to under coat zone in under coat zone single coat of the paint is done on frames and body covers and in this zone coat of paint is done with the help of robots and after that frames and body covers then sent to top coat zone here in this zone second coat of the paint is done and this second coat of paint is done with the operator and after that these frames and body covers are sent to top coat oven

Top Coat Oven In top coat oven these frames and body covers are heated up to 170 degree temperature and dried and then allowed to cool naturally to room temperature and from there it is sent to the inspection zone

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 43

Inspection Zone In inspection zone body covers and frames have to pass infra-red zone Here IR testing machine checks for irregularities in the paint done and after that these body covers and frames are manually checked by hand for any errors in the paint jobs Parts which pass these tests get the OK mark and move to unloading area

Unloading In this area unloading of frames and body covers takes place Frames and body covers having OK mark are loaded to the paint body store and body covers and frames not having OK mark on them are sent to the repair work station and there they fix the problems which frames and body covers have They are then unloaded and then loaded on to the hanger and the parts go to the paint body storage In storage final or finished body covers and frames are stored which from storage area moves to the final assembly line

Problem Analysis Of Carrier

Frame Hole NG

During the motion of the carrier when it is suddenly stopped by the stopper vibrations are produced in it and the pin inserted in the hole of the frame enlarges the size of the hole thereby causing the problem of frame hole NG

To reduce this problem an anti back-up system is applied to reduce the vibrations The NG frame hole is repaired by welding a bush at the site of the hole which is a newly developed Kaizen

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 64

Problems Caused By Loading

Improper loading of the frame body on the carrier damages the insulator collar because an unbalanced force acts upon it and insulator collars being the non-metallic parts are severely affected

R is the resultant vector

This is a production problem which causes the bending of jigs unbalancing of the carrier thereby causing improper motion at the carrier turns and revolutions and also resulting in the body parts falling in the oven

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 65

Gear Box Failure

Gear box of the carrier also fails some time due to overloading or improper coupling

Bending of Striker

Overloading at CTs and CRs causes the bending of the strikers which result in altered motion of the carrier

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 66

Breaking of Post

The post of the carrier can be broken due to variable and unbalanced load acting on the carrier The stresses are developed in the post which leads to its breaking Moreover hammering of the nut for the proper locking can also cause the breaking of nut

Overloading

Overloading is the state when the load on a part of the carrier is higher than its tolerance value Its causes are

If any object interrupts the motion of chain chain is not able to move forward properly causing overloading of chain

Improper position of the jig may lead to unbalancing of the carrier and overload may occur

Guide pin may not properly interact with the arm which may lead to non-alignment

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 67

Chain of the carrier turn may not be in proper position leading to overload at CT

Breaking of any of the carrier dogs will lead to improper revolution of the carrier

Other Problems

Cable breaks -gt Current does not reach to body part

ED COLLECTER burns out -gt It would not collect current

Threading of endndashplate striker wear out -gt Striker would not hit limit switch

Bush between coupling is cut

Bearing sometimes disrupts system

Swivel pipe bends -gt Carrier wouldnrsquot be leveled

Insulator sometimes fails to stop current

End plate threading wears

Spindle shaft bends -gt Carrier wouldnrsquot be leveled

Striker and arm also bends

PRESS SECTION Press section has mainly four machines

Komatsu Pressndash3

AIDA Press -1

CNC bending machine

Hind Press

These presses are mechanical presses and on this press mudguard fuel tank nose and body cover of the scooters like activa aviator dio shine twister unicorn and twister Process like blanking coining and bending of pipes is done

Blanking is cutting up a large sheer of stock into smaller pieces suitable for next operation

Coining is the process of removal of extra material or to make work piece up to the limit All these mechanical presses are of 500 ton and there only one hydraulic press and this press are used to repair the dyes

CNC pipe bending machines are used to bend the pipes which later used in the manufacturing of the frame

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 38

WELDING SECTION In welding section there are six types of welding machines used in manufacturing of frames and body covers

1 Gantry System Gantry system is a system in which gantry crane is used for transporting the frame and welding is done by the robots and welding is finished by the robots the gantry crane picks up the frame and body covers and puts them on the conveyer or the hanger which goes to the weld body storage On gantry system seam welding is done on the body covers and on the frames with the help of the welding robots This system is fully automatic and there is no involvement of human being it picks up the frame and body covers from the location defined to it then does all the processing on it and then passes it to the conveyer

2 MIG Welding Metal inert gas welding in this inert gas argon is used and argon acts as a shielding gas 1-5 oxygen is used This type of welding uses consumable wire electrode during the welding process that is fed from the wire spool MIG welding has some advantages over the other welding techniques It provides a uniform weld it provides a slag free weld beam and needs little clean up

3 Spot Welding Spot welding is a process in which contacting metal surface are joined by the heat obtained from resistance to electric flow and this type of welding is done on the body covers of the scooter

4 Seam Welding It is a process that welds at a surface of overlapped parts along a length of a joint Weld made by overlapping nuggets this type of welding is done on the fuel tanks and mudguards of scooter

5 Portable Spot Welding It is a portable gun which can be taken to specified range where other spot welding machine faces difficulty in welding This type of the welding is done on body covers of scooters

Problem Analysis Of Carrier

Frame Hole NG

During the motion of the carrier when it is suddenly stopped by the stopper vibrations are produced in it and the pin inserted in the hole of the frame enlarges the size of the hole thereby causing the problem of frame hole NG

To reduce this problem an anti back-up system is applied to reduce the vibrations The NG frame hole is repaired by welding a bush at the site of the hole which is a newly developed Kaizen

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 64

Problems Caused By Loading

Improper loading of the frame body on the carrier damages the insulator collar because an unbalanced force acts upon it and insulator collars being the non-metallic parts are severely affected

R is the resultant vector

This is a production problem which causes the bending of jigs unbalancing of the carrier thereby causing improper motion at the carrier turns and revolutions and also resulting in the body parts falling in the oven

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 65

Gear Box Failure

Gear box of the carrier also fails some time due to overloading or improper coupling

Bending of Striker

Overloading at CTs and CRs causes the bending of the strikers which result in altered motion of the carrier

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 66

Breaking of Post

The post of the carrier can be broken due to variable and unbalanced load acting on the carrier The stresses are developed in the post which leads to its breaking Moreover hammering of the nut for the proper locking can also cause the breaking of nut

Overloading

Overloading is the state when the load on a part of the carrier is higher than its tolerance value Its causes are

If any object interrupts the motion of chain chain is not able to move forward properly causing overloading of chain

Improper position of the jig may lead to unbalancing of the carrier and overload may occur

Guide pin may not properly interact with the arm which may lead to non-alignment

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 67

Chain of the carrier turn may not be in proper position leading to overload at CT

Breaking of any of the carrier dogs will lead to improper revolution of the carrier

Other Problems

Cable breaks -gt Current does not reach to body part

ED COLLECTER burns out -gt It would not collect current

Threading of endndashplate striker wear out -gt Striker would not hit limit switch

Bush between coupling is cut

Bearing sometimes disrupts system

Swivel pipe bends -gt Carrier wouldnrsquot be leveled

Insulator sometimes fails to stop current

End plate threading wears

Spindle shaft bends -gt Carrier wouldnrsquot be leveled

Striker and arm also bends

3 Paint Section

PRESS SECTION Press section has mainly four machines

Komatsu Pressndash3

AIDA Press -1

CNC bending machine

Hind Press

These presses are mechanical presses and on this press mudguard fuel tank nose and body cover of the scooters like activa aviator dio shine twister unicorn and twister Process like blanking coining and bending of pipes is done

Blanking is cutting up a large sheer of stock into smaller pieces suitable for next operation

Coining is the process of removal of extra material or to make work piece up to the limit All these mechanical presses are of 500 ton and there only one hydraulic press and this press are used to repair the dyes

CNC pipe bending machines are used to bend the pipes which later used in the manufacturing of the frame

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 38

WELDING SECTION In welding section there are six types of welding machines used in manufacturing of frames and body covers

1 Gantry System Gantry system is a system in which gantry crane is used for transporting the frame and welding is done by the robots and welding is finished by the robots the gantry crane picks up the frame and body covers and puts them on the conveyer or the hanger which goes to the weld body storage On gantry system seam welding is done on the body covers and on the frames with the help of the welding robots This system is fully automatic and there is no involvement of human being it picks up the frame and body covers from the location defined to it then does all the processing on it and then passes it to the conveyer

2 MIG Welding Metal inert gas welding in this inert gas argon is used and argon acts as a shielding gas 1-5 oxygen is used This type of welding uses consumable wire electrode during the welding process that is fed from the wire spool MIG welding has some advantages over the other welding techniques It provides a uniform weld it provides a slag free weld beam and needs little clean up

3 Spot Welding Spot welding is a process in which contacting metal surface are joined by the heat obtained from resistance to electric flow and this type of welding is done on the body covers of the scooter

4 Seam Welding It is a process that welds at a surface of overlapped parts along a length of a joint Weld made by overlapping nuggets this type of welding is done on the fuel tanks and mudguards of scooter

5 Portable Spot Welding It is a portable gun which can be taken to specified range where other spot welding machine faces difficulty in welding This type of the welding is done on body covers of scooters

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 39

6 Fine Boring Fine boring is done on the frame where handle has to fit after fine boring handle is attached to it

When various operation of the welding on the different components of the scooter that is frame mudguard body covers and fuel tank is over then this welded body parts are loaded on to a conveyer hanger which takes these body parts to the weld body storage and in the weld body storage and in weld body storage there are three sections one for model 1 one for model 2 and the last for model 3 When welded body is loaded on to a conveyor then the person who loads these bodies on to the hanger select in which model hanger has to go and the selection is done with a selector switch present Up to 300 hangers can be stored in the storage area that means around 600 frames and 600 body covers can be stored in the weld storage area From storage area hangers move to the unloading area and from unloading area these body covers and frames are loaded on to a Carrier which takes them to the paint section Unloading of the frames and body covers depends on the requirement of the assembly line and which model they are making according to their requirement unloading of model frames and body covers is done Unloading of the model is again done by the selector switch that is when there is requirement of model 1 the person who unloads the frame presses model switch and from storage model 1 moves to the unloading area Similarly when there is requirement of model 2 then operator presses model 2 switch and same goes for the model 3 when the requirement is of model 3 the operator presses the model 3 switch and then from storage model 3 moves to unloading bay

PAINT SECTION Paint section is very important section In this section different treatments are done on the body covers and frames and it is a step by step process done as follows

Loading

Pre-Treatment

Electro-Deposition

ED Oven

Booth

Top Coat Oven

Inspection Zone

Unloading

PAINT PROCESS FLOW

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 41

1 Sanding Zone

2 Under Coat

3 Top Coat

Loading In this process frames and body covers are mounted on the carrier of the conveyor line There are two lines for the paint that is paint A line and paint B line both the lines are very much important because in A line loading of frames and front body left right cover and rear body covers are loaded and on B line mudguard and front cowl is loaded and after loading of these parts then the carrier moves to the pretreatment zone

Pre-Treatment In pre-treatment degreasing and dust cleaning is done In pre-treatment bodies have to undergo two operations first wasting with the soft water by this process degreasing is done and all the dust particles are removed from the frames and body covers In general first we get hard water is converted to soft water by ion exchange mechanism

Secondly on bodies and frames phosphate cleaning is done by this method any dust particle or any grease particle left on the frames and body cover is removed

Electro-Deposition In electro deposition carrier which carries frame and body covers turn down into the electro deposition chamber and in electro deposition chamber is filled with the base paint or primer When carrier turns down it strikes high voltage wire and it gets negatively charged and become cathode and paint in the chamber becomes anode then a uniform thin film of base paint is deposited on

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 42

the body covers and frames of the scooter This process is repeated twice and after that it is passed to ED oven

ED Oven In electro deposition oven base coat done on the frame and body covers is heated to 150 degree temperature and this base coat is dried here and after that is passed to paint booth

Paint Booth Paint booth has three sections first one is sanding zone second primary coat or under coat and third is top coat

In sanding zone sanding of the frames and body covers is done and after that it is sent to under coat zone in under coat zone single coat of the paint is done on frames and body covers and in this zone coat of paint is done with the help of robots and after that frames and body covers then sent to top coat zone here in this zone second coat of the paint is done and this second coat of paint is done with the operator and after that these frames and body covers are sent to top coat oven

Top Coat Oven In top coat oven these frames and body covers are heated up to 170 degree temperature and dried and then allowed to cool naturally to room temperature and from there it is sent to the inspection zone

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 43

Inspection Zone In inspection zone body covers and frames have to pass infra-red zone Here IR testing machine checks for irregularities in the paint done and after that these body covers and frames are manually checked by hand for any errors in the paint jobs Parts which pass these tests get the OK mark and move to unloading area

Unloading In this area unloading of frames and body covers takes place Frames and body covers having OK mark are loaded to the paint body store and body covers and frames not having OK mark on them are sent to the repair work station and there they fix the problems which frames and body covers have They are then unloaded and then loaded on to the hanger and the parts go to the paint body storage In storage final or finished body covers and frames are stored which from storage area moves to the final assembly line

9 ProjectProject Definition

To study the various parts of the carrier being used in the paint shop and its problem analysis

Project Introduction

Carrier is defined as a thing which supports or holds up a part during its movement It is used to carry parts to the paint shop where various processes can be performed Carrier forms the basis of the Paint Shop because the movement of the parts from one point to another in the paint shop takes place only due to carrier The parts are loaded on the carrier with the help of a jig and then the motion takes place

Paint shop carrier is the most important moving part in the paint process Most problems and the breakdowns in the paint shop occur due to the carrier only It causes loss to the net production Bends or breaks due to load of body part applied on carrier causes distortions which ultimately results in the breakdown

Carrier is a part of the conveyer system being used in the paint shop The other components of the conveyer system are the prime mover drive (works as the input motion source for chain) chain and chain track carrier carrier turn (for turning the carrier) carrier

Problem Analysis Of Carrier

Frame Hole NG

During the motion of the carrier when it is suddenly stopped by the stopper vibrations are produced in it and the pin inserted in the hole of the frame enlarges the size of the hole thereby causing the problem of frame hole NG

To reduce this problem an anti back-up system is applied to reduce the vibrations The NG frame hole is repaired by welding a bush at the site of the hole which is a newly developed Kaizen

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 64

Problems Caused By Loading

Improper loading of the frame body on the carrier damages the insulator collar because an unbalanced force acts upon it and insulator collars being the non-metallic parts are severely affected

R is the resultant vector

This is a production problem which causes the bending of jigs unbalancing of the carrier thereby causing improper motion at the carrier turns and revolutions and also resulting in the body parts falling in the oven

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 65

Gear Box Failure

Gear box of the carrier also fails some time due to overloading or improper coupling

Bending of Striker

Overloading at CTs and CRs causes the bending of the strikers which result in altered motion of the carrier

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 66

Breaking of Post

The post of the carrier can be broken due to variable and unbalanced load acting on the carrier The stresses are developed in the post which leads to its breaking Moreover hammering of the nut for the proper locking can also cause the breaking of nut

Overloading

Overloading is the state when the load on a part of the carrier is higher than its tolerance value Its causes are

If any object interrupts the motion of chain chain is not able to move forward properly causing overloading of chain

Improper position of the jig may lead to unbalancing of the carrier and overload may occur

Guide pin may not properly interact with the arm which may lead to non-alignment

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 67

Chain of the carrier turn may not be in proper position leading to overload at CT

Breaking of any of the carrier dogs will lead to improper revolution of the carrier

Other Problems

Cable breaks -gt Current does not reach to body part

ED COLLECTER burns out -gt It would not collect current

Threading of endndashplate striker wear out -gt Striker would not hit limit switch

Bush between coupling is cut

Bearing sometimes disrupts system

Swivel pipe bends -gt Carrier wouldnrsquot be leveled

Insulator sometimes fails to stop current

End plate threading wears

Spindle shaft bends -gt Carrier wouldnrsquot be leveled

Striker and arm also bends

WELDING SECTION In welding section there are six types of welding machines used in manufacturing of frames and body covers

1 Gantry System Gantry system is a system in which gantry crane is used for transporting the frame and welding is done by the robots and welding is finished by the robots the gantry crane picks up the frame and body covers and puts them on the conveyer or the hanger which goes to the weld body storage On gantry system seam welding is done on the body covers and on the frames with the help of the welding robots This system is fully automatic and there is no involvement of human being it picks up the frame and body covers from the location defined to it then does all the processing on it and then passes it to the conveyer

2 MIG Welding Metal inert gas welding in this inert gas argon is used and argon acts as a shielding gas 1-5 oxygen is used This type of welding uses consumable wire electrode during the welding process that is fed from the wire spool MIG welding has some advantages over the other welding techniques It provides a uniform weld it provides a slag free weld beam and needs little clean up

3 Spot Welding Spot welding is a process in which contacting metal surface are joined by the heat obtained from resistance to electric flow and this type of welding is done on the body covers of the scooter

4 Seam Welding It is a process that welds at a surface of overlapped parts along a length of a joint Weld made by overlapping nuggets this type of welding is done on the fuel tanks and mudguards of scooter

5 Portable Spot Welding It is a portable gun which can be taken to specified range where other spot welding machine faces difficulty in welding This type of the welding is done on body covers of scooters

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 39

6 Fine Boring Fine boring is done on the frame where handle has to fit after fine boring handle is attached to it

When various operation of the welding on the different components of the scooter that is frame mudguard body covers and fuel tank is over then this welded body parts are loaded on to a conveyer hanger which takes these body parts to the weld body storage and in the weld body storage and in weld body storage there are three sections one for model 1 one for model 2 and the last for model 3 When welded body is loaded on to a conveyor then the person who loads these bodies on to the hanger select in which model hanger has to go and the selection is done with a selector switch present Up to 300 hangers can be stored in the storage area that means around 600 frames and 600 body covers can be stored in the weld storage area From storage area hangers move to the unloading area and from unloading area these body covers and frames are loaded on to a Carrier which takes them to the paint section Unloading of the frames and body covers depends on the requirement of the assembly line and which model they are making according to their requirement unloading of model frames and body covers is done Unloading of the model is again done by the selector switch that is when there is requirement of model 1 the person who unloads the frame presses model switch and from storage model 1 moves to the unloading area Similarly when there is requirement of model 2 then operator presses model 2 switch and same goes for the model 3 when the requirement is of model 3 the operator presses the model 3 switch and then from storage model 3 moves to unloading bay

PAINT SECTION Paint section is very important section In this section different treatments are done on the body covers and frames and it is a step by step process done as follows

Loading

Pre-Treatment

Electro-Deposition

ED Oven

Booth

Top Coat Oven

Inspection Zone

Unloading

PAINT PROCESS FLOW

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 41

1 Sanding Zone

2 Under Coat

3 Top Coat

Loading In this process frames and body covers are mounted on the carrier of the conveyor line There are two lines for the paint that is paint A line and paint B line both the lines are very much important because in A line loading of frames and front body left right cover and rear body covers are loaded and on B line mudguard and front cowl is loaded and after loading of these parts then the carrier moves to the pretreatment zone

Pre-Treatment In pre-treatment degreasing and dust cleaning is done In pre-treatment bodies have to undergo two operations first wasting with the soft water by this process degreasing is done and all the dust particles are removed from the frames and body covers In general first we get hard water is converted to soft water by ion exchange mechanism

Secondly on bodies and frames phosphate cleaning is done by this method any dust particle or any grease particle left on the frames and body cover is removed

Electro-Deposition In electro deposition carrier which carries frame and body covers turn down into the electro deposition chamber and in electro deposition chamber is filled with the base paint or primer When carrier turns down it strikes high voltage wire and it gets negatively charged and become cathode and paint in the chamber becomes anode then a uniform thin film of base paint is deposited on

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 42

the body covers and frames of the scooter This process is repeated twice and after that it is passed to ED oven

ED Oven In electro deposition oven base coat done on the frame and body covers is heated to 150 degree temperature and this base coat is dried here and after that is passed to paint booth

Paint Booth Paint booth has three sections first one is sanding zone second primary coat or under coat and third is top coat

In sanding zone sanding of the frames and body covers is done and after that it is sent to under coat zone in under coat zone single coat of the paint is done on frames and body covers and in this zone coat of paint is done with the help of robots and after that frames and body covers then sent to top coat zone here in this zone second coat of the paint is done and this second coat of paint is done with the operator and after that these frames and body covers are sent to top coat oven

Top Coat Oven In top coat oven these frames and body covers are heated up to 170 degree temperature and dried and then allowed to cool naturally to room temperature and from there it is sent to the inspection zone

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 43

Inspection Zone In inspection zone body covers and frames have to pass infra-red zone Here IR testing machine checks for irregularities in the paint done and after that these body covers and frames are manually checked by hand for any errors in the paint jobs Parts which pass these tests get the OK mark and move to unloading area

Unloading In this area unloading of frames and body covers takes place Frames and body covers having OK mark are loaded to the paint body store and body covers and frames not having OK mark on them are sent to the repair work station and there they fix the problems which frames and body covers have They are then unloaded and then loaded on to the hanger and the parts go to the paint body storage In storage final or finished body covers and frames are stored which from storage area moves to the final assembly line

9 ProjectProject Definition

To study the various parts of the carrier being used in the paint shop and its problem analysis

Project Introduction

Carrier is defined as a thing which supports or holds up a part during its movement It is used to carry parts to the paint shop where various processes can be performed Carrier forms the basis of the Paint Shop because the movement of the parts from one point to another in the paint shop takes place only due to carrier The parts are loaded on the carrier with the help of a jig and then the motion takes place

Paint shop carrier is the most important moving part in the paint process Most problems and the breakdowns in the paint shop occur due to the carrier only It causes loss to the net production Bends or breaks due to load of body part applied on carrier causes distortions which ultimately results in the breakdown

Carrier is a part of the conveyer system being used in the paint shop The other components of the conveyer system are the prime mover drive (works as the input motion source for chain) chain and chain track carrier carrier turn (for turning the carrier) carrier

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 45

revolution (for revolving the carrier) stopper (it temporarily stops the carrier on line) carrier locks auto feeder cylinders and drop lifters which support the motion of carrier

Part Description Of Carrier

Rail

Rail can be of two types ie pre rail and power rail Pre rail is used to drive trolley of the carrier Power rail is used to drive the conveyer system

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 46

Gear Box

Gear Box acts as a Speed Reducer It consists of a worm and worm-wheel arrangement which turns the axis of rotation by 90deg and reduces the speed of the parts The gear box is coupled with the small sprocket Gear transmits power to small sprocket which helps for carrier turn this is also called as reduction gear The relation between the torque and diameter of worm shaft is given by

T (Kg-m) = π16dsup3τ

where τ is the twisting moment

Velocity Ratio = 160

Tensile Strength of Material = 60 Kgmmsup2

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 47

Trolley

There are two trolleys present in a carrier namely Front and the Rear Trolley Front Trolley stops the carrier at a specified position by the actuation of stopper while Rear Trolley stops the next carrier by engaging with the Front trolley of next carrier Trolley Wheel contains ball bearings The outer race serves as a wheel A grease fitting is installed as a greasing port Guide Roller is installed to reduce friction against free rail Pivoting Dog is lifted by the own weight The chain pusher engages to the Pivoting dog for transport To stop the carrier the stopper (installed on the line) pushes down the Pivoting Dog to release the engagement with the pusher

Swivel Pipe

Swivel pipe is used to drive carrier during carrier revolution Swivel pipe is connected to the shaft of worm gear thus it also gets its power from the gear box

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 48

Big Sprocket

It comes in contact with the chain of the carrier turn and is responsible for rotation of the carrier It is mounted on the spindle on which the pan cover is fixed Four carrier dogs are attached to it which control the rotation of the carrier Big sprocket is attached to the spindle shaft plate

Small Sprocket

It is attached to the shaft connected to gear box It comes in contact with the chain of carrier revolution and is responsible for the revolution of the carrier

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 49

Tension Spring

Spring is used to lock turning plate thus stopping carrier revolution It happens when there is no load on the spring But when the load is applied turning plate opens and hence carrier revolution occurs

Insulator Collar

It provides insulation to the carrier in ED process so that there is no current in the frame To avoid the flow of current in the rail of the conveyer system and to avoid damage to the whole system insulator collars are provided

Post

It is mounted on the pan cover and holds the jig by locking it at its position Post mainly has three parts post cover post spacer and post spacer

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 50

Coupling

Bush Coupling transfers the motion from small sprocket shaft to input shaft To avoid overloading at the gear box bush coupling is provided

Guide Pin Arm

It locks the turning of the Big Sprocket by elongating the spring connected to it It has three contact points one is the spring one touches the guide pin of the carrier turn and third is for the engagement and disengagement of big sprocket

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 51

ED Collector

ED collector is used to collect current during ED process and transmits it through the cables to the body parts

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 52

End Striker amp Turn Striker

They are used to control the turning and revolution of the carrier respectively While end striker controls the revolution of the carrier turn striker controls the rotation of the carrier

1 Sanding Zone

2 Under Coat

3 Top Coat

Loading In this process frames and body covers are mounted on the carrier of the conveyor line There are two lines for the paint that is paint A line and paint B line both the lines are very much important because in A line loading of frames and front body left right cover and rear body covers are loaded and on B line mudguard and front cowl is loaded and after loading of these parts then the carrier moves to the pretreatment zone

Pre-Treatment In pre-treatment degreasing and dust cleaning is done In pre-treatment bodies have to undergo two operations first wasting with the soft water by this process degreasing is done and all the dust particles are removed from the frames and body covers In general first we get hard water is converted to soft water by ion exchange mechanism

Secondly on bodies and frames phosphate cleaning is done by this method any dust particle or any grease particle left on the frames and body cover is removed

Electro-Deposition In electro deposition carrier which carries frame and body covers turn down into the electro deposition chamber and in electro deposition chamber is filled with the base paint or primer When carrier turns down it strikes high voltage wire and it gets negatively charged and become cathode and paint in the chamber becomes anode then a uniform thin film of base paint is deposited on

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 42

the body covers and frames of the scooter This process is repeated twice and after that it is passed to ED oven

ED Oven In electro deposition oven base coat done on the frame and body covers is heated to 150 degree temperature and this base coat is dried here and after that is passed to paint booth

Paint Booth Paint booth has three sections first one is sanding zone second primary coat or under coat and third is top coat

In sanding zone sanding of the frames and body covers is done and after that it is sent to under coat zone in under coat zone single coat of the paint is done on frames and body covers and in this zone coat of paint is done with the help of robots and after that frames and body covers then sent to top coat zone here in this zone second coat of the paint is done and this second coat of paint is done with the operator and after that these frames and body covers are sent to top coat oven

Top Coat Oven In top coat oven these frames and body covers are heated up to 170 degree temperature and dried and then allowed to cool naturally to room temperature and from there it is sent to the inspection zone

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 43

Inspection Zone In inspection zone body covers and frames have to pass infra-red zone Here IR testing machine checks for irregularities in the paint done and after that these body covers and frames are manually checked by hand for any errors in the paint jobs Parts which pass these tests get the OK mark and move to unloading area

Unloading In this area unloading of frames and body covers takes place Frames and body covers having OK mark are loaded to the paint body store and body covers and frames not having OK mark on them are sent to the repair work station and there they fix the problems which frames and body covers have They are then unloaded and then loaded on to the hanger and the parts go to the paint body storage In storage final or finished body covers and frames are stored which from storage area moves to the final assembly line

Problem Analysis Of Carrier

Frame Hole NG

During the motion of the carrier when it is suddenly stopped by the stopper vibrations are produced in it and the pin inserted in the hole of the frame enlarges the size of the hole thereby causing the problem of frame hole NG

To reduce this problem an anti back-up system is applied to reduce the vibrations The NG frame hole is repaired by welding a bush at the site of the hole which is a newly developed Kaizen

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 64

Problems Caused By Loading

Improper loading of the frame body on the carrier damages the insulator collar because an unbalanced force acts upon it and insulator collars being the non-metallic parts are severely affected

R is the resultant vector

This is a production problem which causes the bending of jigs unbalancing of the carrier thereby causing improper motion at the carrier turns and revolutions and also resulting in the body parts falling in the oven

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 65

Gear Box Failure

Gear box of the carrier also fails some time due to overloading or improper coupling

Bending of Striker

Overloading at CTs and CRs causes the bending of the strikers which result in altered motion of the carrier

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 66

Breaking of Post

The post of the carrier can be broken due to variable and unbalanced load acting on the carrier The stresses are developed in the post which leads to its breaking Moreover hammering of the nut for the proper locking can also cause the breaking of nut

Overloading

Overloading is the state when the load on a part of the carrier is higher than its tolerance value Its causes are

If any object interrupts the motion of chain chain is not able to move forward properly causing overloading of chain

Improper position of the jig may lead to unbalancing of the carrier and overload may occur

Guide pin may not properly interact with the arm which may lead to non-alignment

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 67

Chain of the carrier turn may not be in proper position leading to overload at CT

Breaking of any of the carrier dogs will lead to improper revolution of the carrier

Other Problems

Cable breaks -gt Current does not reach to body part

ED COLLECTER burns out -gt It would not collect current

Threading of endndashplate striker wear out -gt Striker would not hit limit switch

Bush between coupling is cut

Bearing sometimes disrupts system

Swivel pipe bends -gt Carrier wouldnrsquot be leveled

Insulator sometimes fails to stop current

End plate threading wears

Spindle shaft bends -gt Carrier wouldnrsquot be leveled

Striker and arm also bends

Problem Analysis Of Carrier

Frame Hole NG

During the motion of the carrier when it is suddenly stopped by the stopper vibrations are produced in it and the pin inserted in the hole of the frame enlarges the size of the hole thereby causing the problem of frame hole NG

To reduce this problem an anti back-up system is applied to reduce the vibrations The NG frame hole is repaired by welding a bush at the site of the hole which is a newly developed Kaizen

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 64

Problems Caused By Loading

Improper loading of the frame body on the carrier damages the insulator collar because an unbalanced force acts upon it and insulator collars being the non-metallic parts are severely affected

R is the resultant vector

This is a production problem which causes the bending of jigs unbalancing of the carrier thereby causing improper motion at the carrier turns and revolutions and also resulting in the body parts falling in the oven

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 65

Gear Box Failure

Gear box of the carrier also fails some time due to overloading or improper coupling

Bending of Striker

Overloading at CTs and CRs causes the bending of the strikers which result in altered motion of the carrier

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 66

Breaking of Post

The post of the carrier can be broken due to variable and unbalanced load acting on the carrier The stresses are developed in the post which leads to its breaking Moreover hammering of the nut for the proper locking can also cause the breaking of nut

Overloading

Overloading is the state when the load on a part of the carrier is higher than its tolerance value Its causes are

If any object interrupts the motion of chain chain is not able to move forward properly causing overloading of chain

Improper position of the jig may lead to unbalancing of the carrier and overload may occur

Guide pin may not properly interact with the arm which may lead to non-alignment

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 67

Chain of the carrier turn may not be in proper position leading to overload at CT

Breaking of any of the carrier dogs will lead to improper revolution of the carrier

Other Problems

Cable breaks -gt Current does not reach to body part

ED COLLECTER burns out -gt It would not collect current

Threading of endndashplate striker wear out -gt Striker would not hit limit switch

Bush between coupling is cut

Bearing sometimes disrupts system

Swivel pipe bends -gt Carrier wouldnrsquot be leveled

Insulator sometimes fails to stop current

End plate threading wears

Spindle shaft bends -gt Carrier wouldnrsquot be leveled

Striker and arm also bends

Loading In this process frames and body covers are mounted on the carrier of the conveyor line There are two lines for the paint that is paint A line and paint B line both the lines are very much important because in A line loading of frames and front body left right cover and rear body covers are loaded and on B line mudguard and front cowl is loaded and after loading of these parts then the carrier moves to the pretreatment zone

Pre-Treatment In pre-treatment degreasing and dust cleaning is done In pre-treatment bodies have to undergo two operations first wasting with the soft water by this process degreasing is done and all the dust particles are removed from the frames and body covers In general first we get hard water is converted to soft water by ion exchange mechanism

Secondly on bodies and frames phosphate cleaning is done by this method any dust particle or any grease particle left on the frames and body cover is removed

Electro-Deposition In electro deposition carrier which carries frame and body covers turn down into the electro deposition chamber and in electro deposition chamber is filled with the base paint or primer When carrier turns down it strikes high voltage wire and it gets negatively charged and become cathode and paint in the chamber becomes anode then a uniform thin film of base paint is deposited on

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 42

the body covers and frames of the scooter This process is repeated twice and after that it is passed to ED oven

ED Oven In electro deposition oven base coat done on the frame and body covers is heated to 150 degree temperature and this base coat is dried here and after that is passed to paint booth

Paint Booth Paint booth has three sections first one is sanding zone second primary coat or under coat and third is top coat

In sanding zone sanding of the frames and body covers is done and after that it is sent to under coat zone in under coat zone single coat of the paint is done on frames and body covers and in this zone coat of paint is done with the help of robots and after that frames and body covers then sent to top coat zone here in this zone second coat of the paint is done and this second coat of paint is done with the operator and after that these frames and body covers are sent to top coat oven

Top Coat Oven In top coat oven these frames and body covers are heated up to 170 degree temperature and dried and then allowed to cool naturally to room temperature and from there it is sent to the inspection zone

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 43

Inspection Zone In inspection zone body covers and frames have to pass infra-red zone Here IR testing machine checks for irregularities in the paint done and after that these body covers and frames are manually checked by hand for any errors in the paint jobs Parts which pass these tests get the OK mark and move to unloading area

Unloading In this area unloading of frames and body covers takes place Frames and body covers having OK mark are loaded to the paint body store and body covers and frames not having OK mark on them are sent to the repair work station and there they fix the problems which frames and body covers have They are then unloaded and then loaded on to the hanger and the parts go to the paint body storage In storage final or finished body covers and frames are stored which from storage area moves to the final assembly line

9 ProjectProject Definition

To study the various parts of the carrier being used in the paint shop and its problem analysis

Project Introduction

Carrier is defined as a thing which supports or holds up a part during its movement It is used to carry parts to the paint shop where various processes can be performed Carrier forms the basis of the Paint Shop because the movement of the parts from one point to another in the paint shop takes place only due to carrier The parts are loaded on the carrier with the help of a jig and then the motion takes place

Paint shop carrier is the most important moving part in the paint process Most problems and the breakdowns in the paint shop occur due to the carrier only It causes loss to the net production Bends or breaks due to load of body part applied on carrier causes distortions which ultimately results in the breakdown

Carrier is a part of the conveyer system being used in the paint shop The other components of the conveyer system are the prime mover drive (works as the input motion source for chain) chain and chain track carrier carrier turn (for turning the carrier) carrier

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 45

revolution (for revolving the carrier) stopper (it temporarily stops the carrier on line) carrier locks auto feeder cylinders and drop lifters which support the motion of carrier

Part Description Of Carrier

Rail

Rail can be of two types ie pre rail and power rail Pre rail is used to drive trolley of the carrier Power rail is used to drive the conveyer system

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 46

Gear Box

Gear Box acts as a Speed Reducer It consists of a worm and worm-wheel arrangement which turns the axis of rotation by 90deg and reduces the speed of the parts The gear box is coupled with the small sprocket Gear transmits power to small sprocket which helps for carrier turn this is also called as reduction gear The relation between the torque and diameter of worm shaft is given by

T (Kg-m) = π16dsup3τ

where τ is the twisting moment

Velocity Ratio = 160

Tensile Strength of Material = 60 Kgmmsup2

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 47

Trolley

There are two trolleys present in a carrier namely Front and the Rear Trolley Front Trolley stops the carrier at a specified position by the actuation of stopper while Rear Trolley stops the next carrier by engaging with the Front trolley of next carrier Trolley Wheel contains ball bearings The outer race serves as a wheel A grease fitting is installed as a greasing port Guide Roller is installed to reduce friction against free rail Pivoting Dog is lifted by the own weight The chain pusher engages to the Pivoting dog for transport To stop the carrier the stopper (installed on the line) pushes down the Pivoting Dog to release the engagement with the pusher

Swivel Pipe

Swivel pipe is used to drive carrier during carrier revolution Swivel pipe is connected to the shaft of worm gear thus it also gets its power from the gear box

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 48

Big Sprocket

Small Sprocket

It is attached to the shaft connected to gear box It comes in contact with the chain of carrier revolution and is responsible for the revolution of the carrier

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 49

Tension Spring

Spring is used to lock turning plate thus stopping carrier revolution It happens when there is no load on the spring But when the load is applied turning plate opens and hence carrier revolution occurs

Insulator Collar

It provides insulation to the carrier in ED process so that there is no current in the frame To avoid the flow of current in the rail of the conveyer system and to avoid damage to the whole system insulator collars are provided

Post

It is mounted on the pan cover and holds the jig by locking it at its position Post mainly has three parts post cover post spacer and post spacer

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 50

Coupling

Bush Coupling transfers the motion from small sprocket shaft to input shaft To avoid overloading at the gear box bush coupling is provided

Guide Pin Arm

It locks the turning of the Big Sprocket by elongating the spring connected to it It has three contact points one is the spring one touches the guide pin of the carrier turn and third is for the engagement and disengagement of big sprocket

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 51

ED Collector

ED collector is used to collect current during ED process and transmits it through the cables to the body parts

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 52

End Striker amp Turn Striker

They are used to control the turning and revolution of the carrier respectively While end striker controls the revolution of the carrier turn striker controls the rotation of the carrier

Problems Caused By Loading

Improper loading of the frame body on the carrier damages the insulator collar because an unbalanced force acts upon it and insulator collars being the non-metallic parts are severely affected

R is the resultant vector

This is a production problem which causes the bending of jigs unbalancing of the carrier thereby causing improper motion at the carrier turns and revolutions and also resulting in the body parts falling in the oven

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 65

Gear Box Failure

Gear box of the carrier also fails some time due to overloading or improper coupling

Bending of Striker

Overloading at CTs and CRs causes the bending of the strikers which result in altered motion of the carrier

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 66

Breaking of Post

The post of the carrier can be broken due to variable and unbalanced load acting on the carrier The stresses are developed in the post which leads to its breaking Moreover hammering of the nut for the proper locking can also cause the breaking of nut

Overloading

Overloading is the state when the load on a part of the carrier is higher than its tolerance value Its causes are

If any object interrupts the motion of chain chain is not able to move forward properly causing overloading of chain

Improper position of the jig may lead to unbalancing of the carrier and overload may occur

Guide pin may not properly interact with the arm which may lead to non-alignment

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 67

Chain of the carrier turn may not be in proper position leading to overload at CT

Breaking of any of the carrier dogs will lead to improper revolution of the carrier

Bush between coupling is cut

Bearing sometimes disrupts system

Swivel pipe bends -gt Carrier wouldnrsquot be leveled

Insulator sometimes fails to stop current

End plate threading wears

Spindle shaft bends -gt Carrier wouldnrsquot be leveled

Striker and arm also bends

9 ProjectProject Definition

To study the various parts of the carrier being used in the paint shop and its problem analysis

Project Introduction

Carrier is defined as a thing which supports or holds up a part during its movement It is used to carry parts to the paint shop where various processes can be performed Carrier forms the basis of the Paint Shop because the movement of the parts from one point to another in the paint shop takes place only due to carrier The parts are loaded on the carrier with the help of a jig and then the motion takes place

Paint shop carrier is the most important moving part in the paint process Most problems and the breakdowns in the paint shop occur due to the carrier only It causes loss to the net production Bends or breaks due to load of body part applied on carrier causes distortions which ultimately results in the breakdown

Carrier is a part of the conveyer system being used in the paint shop The other components of the conveyer system are the prime mover drive (works as the input motion source for chain) chain and chain track carrier carrier turn (for turning the carrier) carrier

Problem Analysis Of Carrier

Frame Hole NG

During the motion of the carrier when it is suddenly stopped by the stopper vibrations are produced in it and the pin inserted in the hole of the frame enlarges the size of the hole thereby causing the problem of frame hole NG

To reduce this problem an anti back-up system is applied to reduce the vibrations The NG frame hole is repaired by welding a bush at the site of the hole which is a newly developed Kaizen

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 64

Problems Caused By Loading

Improper loading of the frame body on the carrier damages the insulator collar because an unbalanced force acts upon it and insulator collars being the non-metallic parts are severely affected

R is the resultant vector

This is a production problem which causes the bending of jigs unbalancing of the carrier thereby causing improper motion at the carrier turns and revolutions and also resulting in the body parts falling in the oven

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 65

Gear Box Failure

Gear box of the carrier also fails some time due to overloading or improper coupling

Bending of Striker

Overloading at CTs and CRs causes the bending of the strikers which result in altered motion of the carrier

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 66

Breaking of Post

The post of the carrier can be broken due to variable and unbalanced load acting on the carrier The stresses are developed in the post which leads to its breaking Moreover hammering of the nut for the proper locking can also cause the breaking of nut

Overloading

Overloading is the state when the load on a part of the carrier is higher than its tolerance value Its causes are

If any object interrupts the motion of chain chain is not able to move forward properly causing overloading of chain

Improper position of the jig may lead to unbalancing of the carrier and overload may occur

Guide pin may not properly interact with the arm which may lead to non-alignment

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 67

Chain of the carrier turn may not be in proper position leading to overload at CT

Breaking of any of the carrier dogs will lead to improper revolution of the carrier

Other Problems

Cable breaks -gt Current does not reach to body part

ED COLLECTER burns out -gt It would not collect current

Threading of endndashplate striker wear out -gt Striker would not hit limit switch

Bush between coupling is cut

Bearing sometimes disrupts system

Swivel pipe bends -gt Carrier wouldnrsquot be leveled

Insulator sometimes fails to stop current

End plate threading wears

Spindle shaft bends -gt Carrier wouldnrsquot be leveled

Striker and arm also bends

Problem Analysis Of Carrier

Frame Hole NG

During the motion of the carrier when it is suddenly stopped by the stopper vibrations are produced in it and the pin inserted in the hole of the frame enlarges the size of the hole thereby causing the problem of frame hole NG

To reduce this problem an anti back-up system is applied to reduce the vibrations The NG frame hole is repaired by welding a bush at the site of the hole which is a newly developed Kaizen

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 64

Problems Caused By Loading

Improper loading of the frame body on the carrier damages the insulator collar because an unbalanced force acts upon it and insulator collars being the non-metallic parts are severely affected

R is the resultant vector

This is a production problem which causes the bending of jigs unbalancing of the carrier thereby causing improper motion at the carrier turns and revolutions and also resulting in the body parts falling in the oven

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 65

Gear Box Failure

Gear box of the carrier also fails some time due to overloading or improper coupling

Bending of Striker

Overloading at CTs and CRs causes the bending of the strikers which result in altered motion of the carrier

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 66

Breaking of Post

The post of the carrier can be broken due to variable and unbalanced load acting on the carrier The stresses are developed in the post which leads to its breaking Moreover hammering of the nut for the proper locking can also cause the breaking of nut

Overloading

Overloading is the state when the load on a part of the carrier is higher than its tolerance value Its causes are

If any object interrupts the motion of chain chain is not able to move forward properly causing overloading of chain

Improper position of the jig may lead to unbalancing of the carrier and overload may occur

Guide pin may not properly interact with the arm which may lead to non-alignment

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 67

Chain of the carrier turn may not be in proper position leading to overload at CT

Breaking of any of the carrier dogs will lead to improper revolution of the carrier

Other Problems

Cable breaks -gt Current does not reach to body part

ED COLLECTER burns out -gt It would not collect current

Threading of endndashplate striker wear out -gt Striker would not hit limit switch

Bush between coupling is cut

Bearing sometimes disrupts system

Swivel pipe bends -gt Carrier wouldnrsquot be leveled

Insulator sometimes fails to stop current

End plate threading wears

Spindle shaft bends -gt Carrier wouldnrsquot be leveled

Striker and arm also bends

9 ProjectProject Definition

To study the various parts of the carrier being used in the paint shop and its problem analysis

Project Introduction

Carrier is defined as a thing which supports or holds up a part during its movement It is used to carry parts to the paint shop where various processes can be performed Carrier forms the basis of the Paint Shop because the movement of the parts from one point to another in the paint shop takes place only due to carrier The parts are loaded on the carrier with the help of a jig and then the motion takes place

Paint shop carrier is the most important moving part in the paint process Most problems and the breakdowns in the paint shop occur due to the carrier only It causes loss to the net production Bends or breaks due to load of body part applied on carrier causes distortions which ultimately results in the breakdown

Carrier is a part of the conveyer system being used in the paint shop The other components of the conveyer system are the prime mover drive (works as the input motion source for chain) chain and chain track carrier carrier turn (for turning the carrier) carrier

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 45

revolution (for revolving the carrier) stopper (it temporarily stops the carrier on line) carrier locks auto feeder cylinders and drop lifters which support the motion of carrier

Part Description Of Carrier

Problems Caused By Loading

Improper loading of the frame body on the carrier damages the insulator collar because an unbalanced force acts upon it and insulator collars being the non-metallic parts are severely affected

R is the resultant vector

This is a production problem which causes the bending of jigs unbalancing of the carrier thereby causing improper motion at the carrier turns and revolutions and also resulting in the body parts falling in the oven

Gear Box Failure

Gear box of the carrier also fails some time due to overloading or improper coupling

Bending of Striker

Overloading at CTs and CRs causes the bending of the strikers which result in altered motion of the carrier

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 66

Breaking of Post

The post of the carrier can be broken due to variable and unbalanced load acting on the carrier The stresses are developed in the post which leads to its breaking Moreover hammering of the nut for the proper locking can also cause the breaking of nut

Overloading

Overloading is the state when the load on a part of the carrier is higher than its tolerance value Its causes are

If any object interrupts the motion of chain chain is not able to move forward properly causing overloading of chain

Improper position of the jig may lead to unbalancing of the carrier and overload may occur

Guide pin may not properly interact with the arm which may lead to non-alignment

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 67

Chain of the carrier turn may not be in proper position leading to overload at CT

Breaking of any of the carrier dogs will lead to improper revolution of the carrier

Other Problems

Cable breaks -gt Current does not reach to body part

ED COLLECTER burns out -gt It would not collect current

Threading of endndashplate striker wear out -gt Striker would not hit limit switch

Bush between coupling is cut

Bearing sometimes disrupts system

Swivel pipe bends -gt Carrier wouldnrsquot be leveled

Insulator sometimes fails to stop current

End plate threading wears

Problem Analysis Of Carrier

Frame Hole NG

During the motion of the carrier when it is suddenly stopped by the stopper vibrations are produced in it and the pin inserted in the hole of the frame enlarges the size of the hole thereby causing the problem of frame hole NG

To reduce this problem an anti back-up system is applied to reduce the vibrations The NG frame hole is repaired by welding a bush at the site of the hole which is a newly developed Kaizen

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 64

Problems Caused By Loading

Improper loading of the frame body on the carrier damages the insulator collar because an unbalanced force acts upon it and insulator collars being the non-metallic parts are severely affected

R is the resultant vector

This is a production problem which causes the bending of jigs unbalancing of the carrier thereby causing improper motion at the carrier turns and revolutions and also resulting in the body parts falling in the oven

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 65

Gear Box Failure

Gear box of the carrier also fails some time due to overloading or improper coupling

Bending of Striker

Overloading at CTs and CRs causes the bending of the strikers which result in altered motion of the carrier

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 66

Breaking of Post

The post of the carrier can be broken due to variable and unbalanced load acting on the carrier The stresses are developed in the post which leads to its breaking Moreover hammering of the nut for the proper locking can also cause the breaking of nut

Overloading

Overloading is the state when the load on a part of the carrier is higher than its tolerance value Its causes are

If any object interrupts the motion of chain chain is not able to move forward properly causing overloading of chain

Improper position of the jig may lead to unbalancing of the carrier and overload may occur

Guide pin may not properly interact with the arm which may lead to non-alignment

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 67

Chain of the carrier turn may not be in proper position leading to overload at CT

Breaking of any of the carrier dogs will lead to improper revolution of the carrier

Other Problems

Cable breaks -gt Current does not reach to body part

ED COLLECTER burns out -gt It would not collect current

Threading of endndashplate striker wear out -gt Striker would not hit limit switch

Bush between coupling is cut

Bearing sometimes disrupts system

Swivel pipe bends -gt Carrier wouldnrsquot be leveled

Insulator sometimes fails to stop current

End plate threading wears

Spindle shaft bends -gt Carrier wouldnrsquot be leveled

Striker and arm also bends

Problem Analysis Of Carrier

Frame Hole NG

During the motion of the carrier when it is suddenly stopped by the stopper vibrations are produced in it and the pin inserted in the hole of the frame enlarges the size of the hole thereby causing the problem of frame hole NG

To reduce this problem an anti back-up system is applied to reduce the vibrations The NG frame hole is repaired by welding a bush at the site of the hole which is a newly developed Kaizen

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 64

Problems Caused By Loading

Improper loading of the frame body on the carrier damages the insulator collar because an unbalanced force acts upon it and insulator collars being the non-metallic parts are severely affected

R is the resultant vector

This is a production problem which causes the bending of jigs unbalancing of the carrier thereby causing improper motion at the carrier turns and revolutions and also resulting in the body parts falling in the oven

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 65

Gear Box Failure

Gear box of the carrier also fails some time due to overloading or improper coupling

Bending of Striker

Overloading at CTs and CRs causes the bending of the strikers which result in altered motion of the carrier

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 66

Breaking of Post

The post of the carrier can be broken due to variable and unbalanced load acting on the carrier The stresses are developed in the post which leads to its breaking Moreover hammering of the nut for the proper locking can also cause the breaking of nut

Overloading

Overloading is the state when the load on a part of the carrier is higher than its tolerance value Its causes are

If any object interrupts the motion of chain chain is not able to move forward properly causing overloading of chain

Improper position of the jig may lead to unbalancing of the carrier and overload may occur

Guide pin may not properly interact with the arm which may lead to non-alignment

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 67

Chain of the carrier turn may not be in proper position leading to overload at CT

Breaking of any of the carrier dogs will lead to improper revolution of the carrier

Other Problems

Cable breaks -gt Current does not reach to body part

ED COLLECTER burns out -gt It would not collect current

Threading of endndashplate striker wear out -gt Striker would not hit limit switch

Bush between coupling is cut

Bearing sometimes disrupts system

Swivel pipe bends -gt Carrier wouldnrsquot be leveled

Insulator sometimes fails to stop current

End plate threading wears

Spindle shaft bends -gt Carrier wouldnrsquot be leveled

Striker and arm also bends

Problem Analysis Of Carrier

Frame Hole NG

During the motion of the carrier when it is suddenly stopped by the stopper vibrations are produced in it and the pin inserted in the hole of the frame enlarges the size of the hole thereby causing the problem of frame hole NG

To reduce this problem an anti back-up system is applied to reduce the vibrations The NG frame hole is repaired by welding a bush at the site of the hole which is a newly developed Kaizen

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 64

Problems Caused By Loading

Improper loading of the frame body on the carrier damages the insulator collar because an unbalanced force acts upon it and insulator collars being the non-metallic parts are severely affected

R is the resultant vector

This is a production problem which causes the bending of jigs unbalancing of the carrier thereby causing improper motion at the carrier turns and revolutions and also resulting in the body parts falling in the oven

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 65

Gear Box Failure

Gear box of the carrier also fails some time due to overloading or improper coupling

Bending of Striker

Overloading at CTs and CRs causes the bending of the strikers which result in altered motion of the carrier

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 66

Breaking of Post

The post of the carrier can be broken due to variable and unbalanced load acting on the carrier The stresses are developed in the post which leads to its breaking Moreover hammering of the nut for the proper locking can also cause the breaking of nut

Overloading

Overloading is the state when the load on a part of the carrier is higher than its tolerance value Its causes are

If any object interrupts the motion of chain chain is not able to move forward properly causing overloading of chain

Improper position of the jig may lead to unbalancing of the carrier and overload may occur

Guide pin may not properly interact with the arm which may lead to non-alignment

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 67

Chain of the carrier turn may not be in proper position leading to overload at CT

Breaking of any of the carrier dogs will lead to improper revolution of the carrier

Other Problems

Cable breaks -gt Current does not reach to body part

ED COLLECTER burns out -gt It would not collect current

Threading of endndashplate striker wear out -gt Striker would not hit limit switch

Bush between coupling is cut

Bearing sometimes disrupts system

Swivel pipe bends -gt Carrier wouldnrsquot be leveled

Insulator sometimes fails to stop current

End plate threading wears

Spindle shaft bends -gt Carrier wouldnrsquot be leveled

Striker and arm also bends

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 64

Problems Caused By Loading

Improper loading of the frame body on the carrier damages the insulator collar because an unbalanced force acts upon it and insulator collars being the non-metallic parts are severely affected

R is the resultant vector

This is a production problem which causes the bending of jigs unbalancing of the carrier thereby causing improper motion at the carrier turns and revolutions and also resulting in the body parts falling in the oven

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 65

Gear Box Failure

Gear box of the carrier also fails some time due to overloading or improper coupling

Bending of Striker

Overloading at CTs and CRs causes the bending of the strikers which result in altered motion of the carrier

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 66

Breaking of Post

The post of the carrier can be broken due to variable and unbalanced load acting on the carrier The stresses are developed in the post which leads to its breaking Moreover hammering of the nut for the proper locking can also cause the breaking of nut

Overloading

Overloading is the state when the load on a part of the carrier is higher than its tolerance value Its causes are

If any object interrupts the motion of chain chain is not able to move forward properly causing overloading of chain

Improper position of the jig may lead to unbalancing of the carrier and overload may occur

Guide pin may not properly interact with the arm which may lead to non-alignment

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 67

Chain of the carrier turn may not be in proper position leading to overload at CT

Breaking of any of the carrier dogs will lead to improper revolution of the carrier

Other Problems

Cable breaks -gt Current does not reach to body part

ED COLLECTER burns out -gt It would not collect current

Threading of endndashplate striker wear out -gt Striker would not hit limit switch

Bush between coupling is cut

Bearing sometimes disrupts system

Swivel pipe bends -gt Carrier wouldnrsquot be leveled

Insulator sometimes fails to stop current

End plate threading wears

Spindle shaft bends -gt Carrier wouldnrsquot be leveled

Striker and arm also bends

Problem Analysis Of Carrier

Frame Hole NG

During the motion of the carrier when it is suddenly stopped by the stopper vibrations are produced in it and the pin inserted in the hole of the frame enlarges the size of the hole thereby causing the problem of frame hole NG

To reduce this problem an anti back-up system is applied to reduce the vibrations The NG frame hole is repaired by welding a bush at the site of the hole which is a newly developed Kaizen

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 64

Problems Caused By Loading

Improper loading of the frame body on the carrier damages the insulator collar because an unbalanced force acts upon it and insulator collars being the non-metallic parts are severely affected

R is the resultant vector

This is a production problem which causes the bending of jigs unbalancing of the carrier thereby causing improper motion at the carrier turns and revolutions and also resulting in the body parts falling in the oven

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 65

Gear Box Failure

Gear box of the carrier also fails some time due to overloading or improper coupling

Bending of Striker

Overloading at CTs and CRs causes the bending of the strikers which result in altered motion of the carrier

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 66

Breaking of Post

The post of the carrier can be broken due to variable and unbalanced load acting on the carrier The stresses are developed in the post which leads to its breaking Moreover hammering of the nut for the proper locking can also cause the breaking of nut

Overloading

Overloading is the state when the load on a part of the carrier is higher than its tolerance value Its causes are

If any object interrupts the motion of chain chain is not able to move forward properly causing overloading of chain

Improper position of the jig may lead to unbalancing of the carrier and overload may occur

Guide pin may not properly interact with the arm which may lead to non-alignment

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 67

Chain of the carrier turn may not be in proper position leading to overload at CT

Breaking of any of the carrier dogs will lead to improper revolution of the carrier

Other Problems

Cable breaks -gt Current does not reach to body part

ED COLLECTER burns out -gt It would not collect current

Threading of endndashplate striker wear out -gt Striker would not hit limit switch

Bush between coupling is cut

Bearing sometimes disrupts system

Swivel pipe bends -gt Carrier wouldnrsquot be leveled

Insulator sometimes fails to stop current

End plate threading wears

Spindle shaft bends -gt Carrier wouldnrsquot be leveled

Striker and arm also bends

Problem Analysis Of Carrier

Frame Hole NG

During the motion of the carrier when it is suddenly stopped by the stopper vibrations are produced in it and the pin inserted in the hole of the frame enlarges the size of the hole thereby causing the problem of frame hole NG

To reduce this problem an anti back-up system is applied to reduce the vibrations The NG frame hole is repaired by welding a bush at the site of the hole which is a newly developed Kaizen

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 64

Problems Caused By Loading

Improper loading of the frame body on the carrier damages the insulator collar because an unbalanced force acts upon it and insulator collars being the non-metallic parts are severely affected

R is the resultant vector

This is a production problem which causes the bending of jigs unbalancing of the carrier thereby causing improper motion at the carrier turns and revolutions and also resulting in the body parts falling in the oven

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 65

Gear Box Failure

Gear box of the carrier also fails some time due to overloading or improper coupling

Bending of Striker

Overloading at CTs and CRs causes the bending of the strikers which result in altered motion of the carrier

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 66

Breaking of Post

The post of the carrier can be broken due to variable and unbalanced load acting on the carrier The stresses are developed in the post which leads to its breaking Moreover hammering of the nut for the proper locking can also cause the breaking of nut

Overloading

Overloading is the state when the load on a part of the carrier is higher than its tolerance value Its causes are

If any object interrupts the motion of chain chain is not able to move forward properly causing overloading of chain

Improper position of the jig may lead to unbalancing of the carrier and overload may occur

Guide pin may not properly interact with the arm which may lead to non-alignment

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 67

Chain of the carrier turn may not be in proper position leading to overload at CT

Breaking of any of the carrier dogs will lead to improper revolution of the carrier

Other Problems

Cable breaks -gt Current does not reach to body part

ED COLLECTER burns out -gt It would not collect current

Threading of endndashplate striker wear out -gt Striker would not hit limit switch

Bush between coupling is cut

Bearing sometimes disrupts system

Swivel pipe bends -gt Carrier wouldnrsquot be leveled

Insulator sometimes fails to stop current

End plate threading wears

Spindle shaft bends -gt Carrier wouldnrsquot be leveled

Striker and arm also bends

Problem Analysis Of Carrier

Frame Hole NG

During the motion of the carrier when it is suddenly stopped by the stopper vibrations are produced in it and the pin inserted in the hole of the frame enlarges the size of the hole thereby causing the problem of frame hole NG

To reduce this problem an anti back-up system is applied to reduce the vibrations The NG frame hole is repaired by welding a bush at the site of the hole which is a newly developed Kaizen

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 64

Problems Caused By Loading

Improper loading of the frame body on the carrier damages the insulator collar because an unbalanced force acts upon it and insulator collars being the non-metallic parts are severely affected

R is the resultant vector

This is a production problem which causes the bending of jigs unbalancing of the carrier thereby causing improper motion at the carrier turns and revolutions and also resulting in the body parts falling in the oven

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 65

Gear Box Failure

Gear box of the carrier also fails some time due to overloading or improper coupling

Bending of Striker

Overloading at CTs and CRs causes the bending of the strikers which result in altered motion of the carrier

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 66

Breaking of Post

The post of the carrier can be broken due to variable and unbalanced load acting on the carrier The stresses are developed in the post which leads to its breaking Moreover hammering of the nut for the proper locking can also cause the breaking of nut

Overloading

Overloading is the state when the load on a part of the carrier is higher than its tolerance value Its causes are

If any object interrupts the motion of chain chain is not able to move forward properly causing overloading of chain

Improper position of the jig may lead to unbalancing of the carrier and overload may occur

Guide pin may not properly interact with the arm which may lead to non-alignment

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 67

Chain of the carrier turn may not be in proper position leading to overload at CT

Breaking of any of the carrier dogs will lead to improper revolution of the carrier

Other Problems

Cable breaks -gt Current does not reach to body part

ED COLLECTER burns out -gt It would not collect current

Threading of endndashplate striker wear out -gt Striker would not hit limit switch

Bush between coupling is cut

Bearing sometimes disrupts system

Swivel pipe bends -gt Carrier wouldnrsquot be leveled

Insulator sometimes fails to stop current

End plate threading wears

Spindle shaft bends -gt Carrier wouldnrsquot be leveled

Striker and arm also bends

Problem Analysis Of Carrier

Frame Hole NG

During the motion of the carrier when it is suddenly stopped by the stopper vibrations are produced in it and the pin inserted in the hole of the frame enlarges the size of the hole thereby causing the problem of frame hole NG

To reduce this problem an anti back-up system is applied to reduce the vibrations The NG frame hole is repaired by welding a bush at the site of the hole which is a newly developed Kaizen

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 64

Problems Caused By Loading

Improper loading of the frame body on the carrier damages the insulator collar because an unbalanced force acts upon it and insulator collars being the non-metallic parts are severely affected

R is the resultant vector

This is a production problem which causes the bending of jigs unbalancing of the carrier thereby causing improper motion at the carrier turns and revolutions and also resulting in the body parts falling in the oven

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 65

Gear Box Failure

Gear box of the carrier also fails some time due to overloading or improper coupling

Bending of Striker

Overloading at CTs and CRs causes the bending of the strikers which result in altered motion of the carrier

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 66

Breaking of Post

The post of the carrier can be broken due to variable and unbalanced load acting on the carrier The stresses are developed in the post which leads to its breaking Moreover hammering of the nut for the proper locking can also cause the breaking of nut

Overloading

Overloading is the state when the load on a part of the carrier is higher than its tolerance value Its causes are

If any object interrupts the motion of chain chain is not able to move forward properly causing overloading of chain

Improper position of the jig may lead to unbalancing of the carrier and overload may occur

Guide pin may not properly interact with the arm which may lead to non-alignment

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 67

Chain of the carrier turn may not be in proper position leading to overload at CT

Breaking of any of the carrier dogs will lead to improper revolution of the carrier

Other Problems

Cable breaks -gt Current does not reach to body part

ED COLLECTER burns out -gt It would not collect current

Threading of endndashplate striker wear out -gt Striker would not hit limit switch

Bush between coupling is cut

Bearing sometimes disrupts system

Swivel pipe bends -gt Carrier wouldnrsquot be leveled

Insulator sometimes fails to stop current

End plate threading wears

Spindle shaft bends -gt Carrier wouldnrsquot be leveled

Striker and arm also bends

NATIONAL INSTITUTE OF TECHNOLOGY KURUKSHETRA Page 68

Conclusion

From my project of one month here in HMSI I came to know that how

work goes on in the organization As far as my project of study

maintenance and breakdown analysis of carrier is concerned I came to

know the importance of carrier in paint shop and the production

problems caused by the carrier in the industry The carrier being used in

the paint shop is the best possible system for proper painting of parts

By knowing the various specifications problems related to it can be

solved
