In our paper inspection conveyor beings with an introduction to material Inspection, it’s various applications. The sensors are used to measure the material dimensions and this signal is given to control Unit. The control unit gives the appropriate signal to the pneumatic cylinder. The pneumatic cylinder is used to collecting mechanism of the improper dimension materials. The inspection conveyor is very useful for material handling in modern engineering industries. The motor is used to drive the conveyor. The materials are transferred from one place to another place by using conveyor. In this top of the conveyor, sensors are used to measure the dimension. This system gives smooth operation and smooth movement of the belts to the jobs at required time. This is a very efficient instrument for checking the dimensions like length, breadth, height etc., to be used in modern engineering industries. The manual efforts can be completely avoided by using this modern equipment. It also reduces the inspection time and manual inspection errors. If the work piece is defective, the pneumatic cylinder placed next to the sensor will be actuated to remove the defective work piece.

WORKING PRINCIPLE:

The 12 volt power supply is used to drive the permanent magnet D.C motor. The two conveyor roller is fixed to the two ends of the frame stand with the help of end bearing (6202) with bearing cap. The conveyor roller shaft is coupled to the D.C. permanent magnet motor with the help of spur gear mechanism. This total arrangement is used to transfer the material from one place to another place with the help of conveyor. The limit sensor switch is vertically fixed on the limit sensor frame stand by means of rack and pinion arrangement. This sensor is used to measuring the abnormal height variation of the material. The rack and pinion is used to adjust the limit switch up and down motion. This arrangement is used to set the height of the material. The IR transmitter and IR receiver circuit is used to sense the minute height variation of the material. It is fixed to the frame stand with a suitable arrangement. This mechanism is also adjustable with the help of bolt and nut. The pneumatic cylinder is fixed to the frame stand by right angles to the limit sensor frame stand. This cylinder arrangement is used to remove the dimensionless material from the conveyor. The pneumatic cylinder is controlled by the flow control valve, single acting solenoid valve and control unit.
