DESIGN OF PLC CONTROLLED PNEUMATIC OPERATED BOX SEGREGATION SYSTEM

摘要

Pneumatic system and its control are commonly used in industrial automation and rationalisation. The automation, integrated control system and mechanism are becoming popular in every field and packaging industries are no exception. Micro computer based control mechanism, control sensor, measurement and mechanical drives, and pneumatic/hydraulic actuation system together forms highly flexible form of automated control in the field of mechatronics. In this work, the feasibility design of a Programmable Logic Controller (PLC) based box segregation system is aimed to segregate boxes of different sizes/heights moving on a flat bed conveyor. Proximity sensor is used to distinguish box sizes and sends signal to the PLC controller which in turn energizes solenoid controlled DC value to actuate pneumatic actuator system to segregate the boxes. The system developed is much of industrial importance and can be modified for different other applications too.
