ABSTRACT

In piping related industries pipes are lifted and placed at desired places using

various techniques like lifting them using chains anchored at either open ends

or just by wrapping the chains around circumference of the pipes. But all

these techniques require extra manpower and consume lot of time also the

huge pipes are very difficult to balance there by requiring great skill to do the

job.

One way of over coming cons associated with this conventional working

method is to use vacuum based lifting techniques. In this technique a vacuum

suction pad is placed over the pipe to be lifted. This suction pad is connected

to a vacuum pump which then creates vacuum inside the pipe cavity which is

connected to the vacuum suction pad. Thus the pipe to be lifted gets attached

to the vacuum suction pad which can be lifted by a crane to get the pipe

lifted. The pipe thus lifted can be placed then at desired place just by letting

air inside the vacuum suction pad. This technique requires no extra human

power, the crane operated can place the suction pad over the pipe and lift and

put the same at desired place. Also this technique consumes less time.

iii

The project work includes building a scale down model of vacuum lift

machine which includes a robotic crane that can maneuver over a flat

surface. This crane has got a robotic arm to which a vacuum suction pad is

connected; to this suction pad a vacuum pipe is connected which at the end id

fixed to a vacuum pump. This vacuum pump is a centrifugal blower that

blows out air and thus creates vacuum. The entire project works on battery

power. All motors used in the project work are DC motors and are controlled

through a wired remote. In the project work small specimen of pipe is lifted

and placed using vacuum power and robotic crane device and thus working

principle is exhibited.The project model is crafted out using aluminum, steel,

MDF, DC motors, controller switches, cables, nut & bolts, screws, plastic

pipes etc.

INTRODUCTION

In various industries lifting and pulling of something happens every

second in million count across this globe.

Much time is wasted in lifting of material with hoist or cranes etc. If

this time is reduced to minimal then whole handling of equipment can be

made more efficient.

A vacuum lifting apparatus is disclosed for lifting large, heavy objects,

wherein the lifting surface of the object deviates somewhat from a planar

configuration as in the case of manufacturing deficiencies or where the object

is of a flexible nature. A frame has opposed surfaces with a generally

peripheral deformable closed-cell resilient gasket partially secured to one

surface of the frame along the inner peripheral portions of the gasket in an

endless arrangement which defines an open chamber with the frame. A

source of reduced atmospheric pressure such as a vacuum pump, selectively

communicates with the chamber through a valve, such that positioning the

gasket member against the object and drawing a vacuum in the chamber thus

creates an atmospheric grip between the frame and the object whereby the

object may be lifted by lifting the frame. If the lifting surface is inaccurate, or

when the object flexes and assumes a curbed configuration, the partial

attachment of the gasket thus permits the gasket to decompress and to flex in

accordance with the curvature of the object, thereby maintaining the vacuum

within the chamber.

In this project an attempt is made to lower down this handling time

material by a new concept called VACUUM LIFT.

Table:-1.1 Mechanical Lifting Equipment Summary

CONCEPT

Vacuum lift is nothing but as have suggest a technique that lifts and

places material with vacuum suction head is placed over a material to be lift

and vacuum pump stained due to vacuum created the material get stuck to

vacuum head which then can be lift by a conventional means like hoists, ram

and cranes etc.

The vacuum is created with the help of simple high speed blower type

pump. The project is carried out on a smaller / scale down version robot is

constructed which can be controlled using sensible controls that has a cam

and is made mobile using caterpillars. On this robot vacuum lift assembly is

mounted.

WHAT IS VACUUM LIFT?

In fact everything on Planet Earth is resisting a force of 1 atmosphere

(101.3 Kpa.) at sea level. This means that a force of 101.3 KN is acting on

an area of 1 square meter. This constant energy force provided by nature is

utilized by Kilner Vacuum lifting devices. The power of vacuum is

harnessed by using specially designed vacuum pads to grip the load.

Vacuum pads can be used individually or in multiples to suit the lifting

operation and can be built into special lifting frames called Vacuum Beams.

These beams are suspended from overhead lifting gear, hoists, fork lift trucks

or built into special purpose vacuum transfer machines.

Another type of vacuum lifting device uses vacuum to lift and grip the

article or load, eliminating the need for a conventional hoist. This equipment

was specially designed for manual handling applications and is called

'LIFTMATE'. See manual handling in our product area.

HISTORY

A vacuum tube lift device and a method for movement of a load by

means of a vacuum tube lift device FIFELD OF THE INVENTION THE

present invention relates to a vacuum tube lift device.

Background of the Invention and Prior Art:

Conventional vacuum tube lift devices have a flexible, vertically

disposed lifting tube, being suspended at its upper end and connected to a

vacuum source for regulating the pressure in the lifting tube. Some kind of

lifting attachment can be a book or a suction cup of the like which can be

coupled to a load which is to be lifted.

Further, the lifting tube is extendable and retractable, i.e. the lifting

tube can be compressed and extended in its longitudinal direction

(vertically). Accordingly, the lifting tube can be maneuvered by means of the

vacuum source so that the tube is compressed along is its point of suspension,

and the tube is extended when lowering the object. For this purpose the

lifting tube usually is constituted of a wire frame in the form of a helical

spring usually called a helical frame, and a cover of a substantially airtight,

flexible material enclosing the frame.

In one type of vacuum tube lift devices the lifting tube is provided with a

lifting attachment in the form of a suction foot, utilizing the vacuum in the

lifting tube for suctioning onto an object, which is to be lifted. Such a lifting

device has the advantage that an object, which is to be lifted, can be attached

to and released from, respectively, the lifting tube in a simple and reliable

way by means of regulating the pressure inside the lifting tube and the

suction foot.

Regardless of the selection of lifting attachment, however the above

described vacuum tube lift device has the disadvantage that it has a large

installation height in relation to the lifting height capacity the lifting tube can

be compressed to a smallest possible length. The length of the lifting tube in

a state of maximum compression length, and the desired effective lifting

height substantially make up the total instillation height of the lifting device.

The relatively large compressed length, usually amounting to approx .25-

30of the installation height implies that a lifting device of the type in

question cannot be used in many spaces having a ceiling height, which is too

low in relation to the desired lifting height capacity

There is another type of vacuum tube lift devices in which the lifting

tube instead is arranged horizontally and is connected to additional vertical

component in order to take care of the vertical lifting movement. This

additional component can be a wire being provided with a hook, or the like,

for coupling to a load. In a order to achieve the vertical movement, the wire

is arranged to travel over a pulley.

Such a device, however, has the disadvantage that it instead occupies a

large space in the horizontally plane, as the entire length of the lifting tube

has to be oriented horizontally. This limits the possibility to get the desired

working areas in the horizontal plane, since the long lifting tube will be an

obstacle in certain positions. The lifting device becomes ungainly and slower

and less flexible to work with.

Another disadvantage with such a device is that a lifting attachment in the

form of suction foot cannot be used without special arrangements. The safety

of vacuum tube lift devices is based upon the fact the vacuum level in the

suction foot is the same as in the lifting tube.

In this way, it is ensured that there is always a sufficient suction force

between the suction foot and the object, which is to be lifted.

In conventional vertical vacuum tube lift device, this is accomplished

by means of the suction foot being connected to the vacuum in the lifting

tube without any flow restriction between the lifting tube and the suction

foot. Therefore, the vacuum level will always be substantially same in both

the suction foot and the lifting tube.

In vacuum tube lift device having a horizontally arranged lifting tube,

the suction foot is connected to the wire and located at a relatively large

distance from the lifting tube, implying on one hand that relatively long

vacuum lines are required between the suction foot and the lifting tube and

on the other hand, that a time delay is created before the vacuum in the lifting

tube and the vacuum in the suction foot have assume the same level. In

certain cases, the vacuum level never assumes the same level, e.g. when

‘leaking’ goods are lifted. In that case, the flow restrictions between the

suction foot and the lifting tube being caused by the pressure drop of the

vacuum lines, results in vacuum level in the suction foot always being lower

than in the lifting tube. Since the air leaking reaches the suction foot before it

reaches the lifting tube via the vacuum lines. The result of forgoing can be

that suction force in the suction foot becomes too low in relation to the lifting

force so that suction foot come loose from the goods which are to be lifted.

In order to solve the problem with the vacuum level which is too low

in the suction foot the device can be provided with a valve arrangement, by

means of which vacuum level in the suction foot increase before it is

increased in the lifting tube and reduced in the suction foot, respectively.

This design however, is relatively complicated in comparison to a

conventional vertical vacuum tube lift device the reason for this is the long

vacuum lines which bring about the flow restrictions, said flow restrictions in

its turn delaying the vacuum level from assuming the same value in the entire

system.

CONSTRUCTION

In its simplest construction, two cater pillar base are made using

robotics parts such as grooved main wheel, plastic supporting wheels and

rubber caterpillar track. These caterpillar belts are powered by DC motor of

2V DC 2400 rpm mesh coupled with fixed reduction ratio gearbox (100: 1 )

for each caterpillar. The assembling this formed form base for the entire

project work. These caterpillars are together with studs 911 in length. The

body of caterpillar and other parts in this project are manufactured from 8

mm / 12 mm MDF sheet (medium density fiber cum hardwood plywood).

Hoisted on caterpillar base, two major parts can be identified

Vacuum pump

Robotic arm.

Fig 5.2:- constructional diagram of vaccum lifter

1. Vacuum Pump:

Let us see the construction of Vacuum pump in detail - The vacuum

pump consists of a high speed 4000 rpm @ 12 V DC motor coupled directly

with a simple blower, fan blade. The whole assembly in of high density

PVC. 3" end in further reduced to 0.5" and tube is fitted having length

approximately'. The other end of tube is fixed to the arm end with vacuum

suction head which is approximately 0.5" x 211 x 0.5" in size and whole

counter are made in such a way to fit profile of that of a 211 pipe. The-

vacuum pump motor is made run a 12V DC 5 amp, so as to work with full

fledge.

Fig 5.3:- Vacuum Pump

2. Robotic Arm:

It is constructed from MDF, Studs, motor, gear boxes, pulleys, Belts,

ropes, etc. In all arm made is moved through five directions, the first one is

vertical having total travel of about 8`which is managed using lead screw

arrangements. The second one is circular motion which enables arm to move

through using belt and pulley arrangement. The fifth motion is swing

motion that can be managed through with an arm mounted on motor

shaft directly. The motion to every mechanism is given using a reduction

gear box meshed with DC motor.

For controlling a robot a control panel is made that encorporates

various switch to make each motor on and off the switch used for this

operation are push on type button except the vacuum pump motor each

motor revolve in reversible direction i.e. clockwise and anticlockwise using

six pins toggle switch for supplying power to each rotor a power supply is

managed.

1) Joints and Links:

A joint of an industrial robot is similar to a joint in the human body. It

provides relative motion between two parts of the body. Each joint or axis as

it is sometimes called provides the robot with a so-called degree-of-freedom

(d.o.f.) of motion. In nearly all cases, only one degree-of-freedom is

associated with a joint. Robots are often classified according to the total

number of degree-of freedom they possess. Connected to each joint are two

links, an input link and an output link. Links are the rigid components of the

robot manipulator. The purpose of the joint is to provide controlled relative

movement between the input link and the output link.

Robots have mechanical joints that can be classified as;

a) Rotational joint (Type R. Joint):- This type provides rotational relative

motion, with the axis of rotation perpendicular to the axes of the input and

output links.

Fig 5.4:- Rotational joint

b) Revolving joint (type V joint):- V from the "V" in revolving. In this join

type, the axis of the input link is parallel to the axis of rotation of the joint,

and the axis of the output link is perpendicular to the axis qf rotation.

Fig 5.5:- Revolving joint

2)Body-and-Arm Configurations:

Given the five types of joints defined above, there are 5 x 5 x 5 = 125

different combinations of joints that can be used to design the body- and-

arm assembly for a three-degree-of-freedom robot manipulator. In addition,

there are design variations within the individual joint types (e.g., physical

size of the joint and range of motion). It is somewhat remarkable, therefore,

that there are only five basic configurations commonly available in

commercial industrial robots. These configurations are;

a) Jointed-Arm Robot :

This robot manipulator has the general configuration of a human arm.

the jointed arm consists of a vertical column that swivels about the base

using a T joint. At the top of the column is a shoulder joint (shown as an R

joint in our figure), whose output link connects to an elbow joint (another R

Joint).

Other part of robot is arm, which is constructed from MDF (medium density

fiber cum hardwood plywood), studs, motors, gearboxes, pulleys, belts,

ropes etc. In all the arm made is move through five degree or directions.

The first one is vertical having total travel of about 8' which is

managed by lead screw arrangement. The motor with reduction gearbox

(100 : 1) are attached vertically above column.

The second motor mounted on vertical column and through pulley and

belt arrangement moves the arm in circular motion. This motion enables to

arm move through 180°.

All and every motion on mechanism given by using a constant mesh

compound dear train gearbox with reduction ratio (100 : 1). It is for provide

accuracy and to increase torque and load bearing capacity by retarding speed

of motor. All motors are DC motors directly mesh with gearbox.

For controlling a robot a control panel is made that incorporated

various switches to make each motor .ON and OFF. The switches used for

this operations are 'Push on' type buttons except the vacuum pump motor.

Each motor are made to work in reversible direction i.e. clockwise and

anticlockwise using 'Fix pin toggle switch'. For supply is managed.

COMPONENTS

1) Motor :

The motors used in this project are permanent magnet type, DC

motor. They all are non regulated and are of two voltage type - 2V DC and

9V DC. Both types of motors are 2400 rpm motors at their relative

corresponding pick voltage value.

2) Pulley:

It is made up of 8 mm thick MDF sheet which is freely hinged on

vertical nut and bolt arrangement to supporting structure which move relative

to lead screw and nut arrangement.

3) MDF:

MDF is short form medium density fiber cum hardwood plywood.

Two types of MDF sheets are used one is 8 mm thick and other is 12 mm

thick. This is used for maximum body work. MDF sheet having high bearing

load capacity and also it is light in weight. It provides smooth finishing and

cut easily by cutting operations.

4) Studs:

Standard number stud is used having 5 mm diameter and 9" length

made up of steel.

5) Lead Screw:

Lead screw having 5 mm diameter and 6" length lead screw and

operated circular motion in vertical axis by use of motor.

6) Gear Box:

Gear box used are reduction .type with 100: 1 reduction ratio. Whereas

first and last gears are solo gears and all are duplex one.

Advantages and disadvantages of gear box:

The two main disadvantages are

You lose speed

You have added weight for the gearbox.

Advantages to using gear reduction

You bring the boot down to a manageable speed

The motor doesn't have to work as hard to spin the wheel which means

it won't draw as much current from your batteries.

Along those lines, the torque produced by the output is inversely

proportional to the amount of reduction in the gear box. Say what?

Basically, if you have a 4:1 gear box then the bot moves 1/4 as fast but

has 4 times the torque! So you can have a 120 pound = 533 N robot

with the right gearing that will push a 400 pound = 1776 N load across

the floor.

7) Cable:

All types of cables are made from FRC cable, ribbon wire and high

ampere rating cable for vacuum pump.

Fig 6.1:- Cable

8) Aluminum Sheet:

This is 3 mm thick aluminum sheet used generally in arms.

9) Power Supply :

This carries three types of voltage 3V, 6V and 12 V DC zand two types of

ampere rating 2 amps and 5 amps.

Fig 6.2:-Battery

10) Toggle :

Six pin toggle switch are used. By this each motors made to work in

reversible manner i.e. clockwise and antic1ockwise.

11) Push button :

Push to on button are used with toggle switch

made to get fixed over the object to be lift by making various combination of

toggle switches and moving arm with the help of push button.

Once the arm is over the material, the material to be lift the vacuum

pump made on as these objects lift. Again object is placed where derived by

moving arm to desired place. The object is place required position by turn off

vacuum pump. By used of caterpillar the object or robots are moved to

different location. This made it for multipurpose material handling

equipment. Thus entire project can exhibits in its working in fewer steps

only.

Fig 8.1: - Actual Working of vaccum lifter

Air Suction Lifter:

The present invention concerns a air suction lifter, more precisely a

lifter for moving packages by means of the suction created inside a chamber

by a source of vacuum. In greater detail, the invention concerns a suction

lifter specially designed to be used safely and reliably on non-rigid packaging

such as cloth or paper sacks and the like. The suction lifters known at present

consist of a single suction chamber which is generally cylindrical in shape,

with one open end, across. which a part of the surface of the package is

subject to suction and deformation.

Inside the suction chamber, parallel to the open base, there is a

perforated plate, or limiter. This structure bears against and retains the area of

the upper face, subject to suction and deformation, of the package or sack to

be moved i.e. lifted, transported or deposited.

To try to conserve the high value of the low pressure inside the suction

chamber after the grip on the package has been established and maintained,

the lower edge of the outside walls of the suction chamber are fitted with air-

tight elements e.g. seals. Once the vacuum has been established and an area

of the surface of the package has been gripped, the package is moved as

desired and later released by interruption of the suction.

The main drawback of the traditional lifting device as above illustrated

is the ineffective seal obtained between the edge of the suction chamber and

the package, especially if the package is a sack (which is so in the majority of

cases).

Actually, creases or folds on the upper surface of the sack, especially

in the area involved in the suction, are formed which can extend into the area

in contact with the aforementioned perforated plate and pass under the air-

tight seal means.

In this way the folds connect the suction chamber to the outside

atmosphere and drastically reduce the level of vacuum in the suction

chamber. Because of said reduction, the flow rate of air sucked from the

chamber has to be considerably increased to maintain the grip on the package

or sack in question. Despite this, the hold on the sack remains precarious and

it is often sufficient just to jolt the sack while it is suspended to alter

negatively the balance between the air entering the chamber and the sucked

air, thus causing the sack being lifted to fall. Further, because of the

difficulties described above, the equipment required to guarantee a sufficient

suction is so large that it can be moved only with great difficulty, thus

detracting from the flexibility required of similar devices.

Finally, because of the stated disadvantages, different sized suction chambers

are required depending on the kind of packages (sacks) to be moved.

There is then a necessity for a suction lifter which safely moves non rigid

packages, and in particular sacks of different sizes. Further, such lifter should

be operated by vacuum sources that are sufficiently small to be easily moved.

Accordingly, an object of the present invention is to solve the above

problems with the suction lifter which gives the maximum reliability in the

movement of non-rigid packages of various size and weight, and achieves a

high level of vacuum with a low suction flow rate.

Essentially, according to the invention a lifter of the suction, or

vacuum, type is provided, especially for the movement of products in non-

rigid packaging such as sacks or similar, characterized in that it comprises

two suction chambers, one of which, being smaller, is located inside the

second chamber, both chambers being open at the end which contacts the

package to be moved, and Being provided, on the edge of said side, with air-

tight seal means on said package to be moved.

ADVANTAGES

Less ground personnel required, reducing the risk of accidents.

Quicker pipe handling.

Less damage to the pipe, coating and bevel, as the only contact with

the pipe is the rubber pad-seal.

The lifting force is divided over the surface area of the suction-pad,

preventing point loading. This is especially important to prevent

damage to the inner concrete lining of some pipes.

An excavator can be fitted with a pipe-lifter for handling pipes and can

be converted back to digger and vice-versa, reducing the amount of

construction machinery required on site.

Pipes can now be stockpiled without spacers.

Handles almost any type of pipe, such as steel, PVC, and concrete.

DISADVANTAGES

Initial cost is more.

Requires a similar vaccum pad to the thing which is to be lift.

FUTURE SCOPE

This project can be improved of some fronts like the capacity of

suction pump and vacuum pump can be improved by using vane type blower

on centrifugal suction pump.

And additional suction pump can be mounted for handing, transferring

of liquid materials.

The robot can be made fully automated with predefine functionalities,

etc.

USES AND BENEFITS

Vacuum lifting equipments can be designed to LIFT, HOLD, TURN,

TILT or ROTATE.

Almost anything can be handled such as steel, glass, concrete, plastics,

wood, aluminum, pipes, refrigerators, aircraft sections, drums, cartons,

round shaped profiled objects can be handled.

Life in safety

Gain increased productivity

Prevent back injury

Automate production

Reduce operator fatigue

Eliminate product damage

Improve working conditions

Handle delicate, hot awkward items.

APPLICATIONS

This project can find its applications in various fields, as technique is simple

and workable. More over this technique reduces material handling time and

make tedious job easier in certain kind of material like pipe handling etc. The

probable industries where this project can be of very much use are as

follows: -

Pipe manufacturing

Pipe handling/ carrying

Glass manufacturing

Cylinder manufacturing

Manufacturing of any delicate items

General purpose manufacturing

Chemical plants

Warehouses

Logistics

Ship Building

Assembly of big parts such as Aircrafts and space ship

industries

Any manufacturing plants where isolation is required / foreign

interference is avoided.

CONCLUSION

The project work done displaced results as expected with its immense

capabilities it may be said that this type of device may prove to be popular

material handling devices.

In Indian subcontinent this device may also be popular and it makes the

whole procedure of material handling efficient and as Indian economy is

booming, this may give a kind of beverage to implementation of such kind of

efficient device.
