Automatic Pneumatic Power Based Object Sorting System by Using MITSUBISHI PLC

Abstract

This paper presents the Automatic Pneumatic Power Based Object Sorting System by Using MITSUBISHI PLC. PLC stands for Programmable Logic controllers. The purpose of the project is to provide low power object sorting with pneumatic pushing system. This project or idea is the basic need of almost every type of manufacturing and production unit today like Food/ Beverage, Metal, Mining, Power, Textile, Automobile, Chemical, Pharmacy, soft & hard drink manufacturing industries etc are the few examples where we see the automation today. The main objective of the project mainly follows two sequential steps. First step is to detect the size of the object by using IR detectors. IR detectors are placed at three different places in order to find out three different sizes of objects. In the second stage, the Pneumatic pusher will push the object. Here three pushers are used to push the objects, which will operate based on the size of the object. Whenever the object is detected then solenoid valve will be opened automatically and then the Pneumatic power will be released through valve to actuator named as pusher. Quantity of the objects in the field is sensed by the IR sensors and fed as inputs to the Q series PLC which in turn are sent to system through Ethernet for necessary processing steps. A PLC program will be developed based on the signals received from the input module of PLC and the signals to the field devices from output modules of PLC, which are interfaced with the PLC output modules.
