I CAN MOVE ANY PARTS

Proposed systemThe pneumatic belt conveyor is equipment

and it is very useful for material handling in modern engineering industries.

It is operated by pneumatic system.

OBJECTIVE:In this project pneumatic belt conveyor using

to moving materials from one location to another.

NEED FOR AUTOMATION: Automation can be achieved through computers, hydraulics, pneumatics, robotics, etc., of these sources, pneumatics form an attractive medium for low cost automation.

The main advantages of all pneumatic systems are economy and simplicity.

Benefits of automation :To achieve mass productionTo reduce man power To increase the efficiency of the plant To reduce the work loadTo reduce the production costTo reduce the production timeTo reduce the material handling To achieve good product qualityLess maintenance

Literature survey

PNEUMATICS

The word ‘pneuma’ comes from Greek and means wind.

The word pneumatics is the study of air movement and its phenomena is derived from the word pneuma.

COMPRESSIBILITY OF AIR FOUND PRODUCT OF PRESSURE AND VOLUME OF PARTICULAR QUANTITY (Robot Boyle IEEE Member)

The compressibility of the air was first investigated by Robot Boyle in 1962.

This can be written as PV =C

(or) P1V1 =P2V2

Any gas can be used in pneumatic system but air is the mostly used system now a days.

PNEUMATIC POWER:Pneumatic systems use pressurized gases to

transmit and control power. pneumatic systems typically use air as the fluid medium because air is safe, low cost and readily available.

PNEUMATIC ROTOR It is used to drill rock and break up pavement, among

other applications.A pneumatic drill or jackhammer is a portable

percussive drill powered by compressed air.

CONNECTORS In our system there are two type of connectors used.

Hose connector reducer.

These types of connectors are made up of brass (or) aluminum (or) hardened pneumatic steel.

BELTA Belt is a looped strip of flexible material. It is used to mechanically link two or more rotating shafts.They may be used as a source of motion, to efficiently

transmit power, or to track relative movement.Belts are looped over pulleys.

HOSESHoses used in this pneumatic system are made up of

polyurethane. These hose can with stand at a maximum pressure level of

10 x 105N/m2 .

WORM GEAR A worm gear is type of mechanical gear.Worm gears are used when large gear reductions are needed. It is common for worm gears to have reductions of 20:1, and

even up to 300:1 or greater.

ADVANTAGES OF WORM GEARHighly accurate. Runs forward and backward. High overload capacity. Stable transmission with reduced vibration and noise.

THE ADVANTAGES OF PNEUMATICS:Pneumatic systems are simple and economical. Control of pneumatic systems is easier Idle time of the

machine is reduced.When compared with the ordinary conveyer it consumes

less time for transporting the job. It reduces the manual labor.Hence production rate is high.

THE DISADVANTAGES OF PNEUMATICS:

Pneumatic systems exhibit spongy characteristics due to compressibility of air.

Initial cost is highMay be a choice of air leakage

APPLICATIONS

In all small and medium scale industries.Material transportation from one to another.
