Abstract: In many industrial applications, there is need of sorting. Sorting can be done by using many ways like sorting of object according to their dimensions, according to their colours, according to their weight, using machine vision (image processing), according to the material of an object etc. For example, in Thermal Power Station, electromagnetic sorting technique is used to sort ferromagnetic materials from coal. In this project, the development of a LCA system to sort objects according to their colour has been designed. PLC controls this LCA system. This project consists of two parts, first consisting of software, which contains ladder logic programming, which is used to program PLC that controls the whole process of the project systematically according to input data sequence. Second is the hardware part, which consists of conveyors, used to transport the objects, sensors used to sense the colour (i.e. colour sensors) of the objects, electronic system used to sort the objects and motors to drive the conveyor belt. The objects are being sorted according to their respective colour. The main conveyor is supported of two branches to load the distinguished object on to the respective one as separated by the electronic system and detected by the proximity sensors. PLC Based Automatic Object Sorting

Keywords: Programmable Logic Controller (PLC), LCA (Low Cost Automation), SCADA Supervisory Control and Data Acquisition

I. INTRODUCTION

This paper here aims in designing a real time application which helps in sorting the objects of any kind using PLC. This system helps in achieving effective communication between objects using multiple sensors to monitor parameters like height, weight, physical and chemical properties etc. The modules interfaced with the PLC for this system are, Photo sensor and Limit switch are used to detect any object, DVD Drives for placing the objects, Inductive sensor for detecting metal objects. A PLC is used to establish communication between sensors for measuring continuously the above real time process. This work introduces an Automatic system with a combination of PLC having high impact on Object sorting. In India, Steel Plant is one of the Navarathna Company which has largest units of manufacturing with its various stages.
