Abstract

Nowadays, majority of industrial, commercial and domestic world used the automation technology to control, sense, regulate and instruct itself to accomplish the tasks. My aim is to create a sorting system based on colour for the use in industry. The sorting system is a system which sorts the object according to their colour. With the Programmable Logic Controller (PLC) as a main controller for the system, the object which is colouring box places on the conveyor automatically using the double acting cylinder A. Cylinder B acts as an actuator to block or prevent the box from passing through so that the colour sensor has enough time to determine the colour of object. The main part for the colour sensor is Light Dependent Resistor (LDR) which detects light intensity. The output voltage sensed by the LDR also decides which pilot lamp should activate according to colour determined. After completed colour sensor part, the conveyor will turn on and move the box. The sorting system completed once the optimal sensor sensed the object and sort box in place. In this project, there are four different colour objects used for demonstrating the sorting system. The result shown that the prototype of colour sorting system able to run in moderate motion. The prototype project can help to eliminate the human error in the sorting process. Besides that, automatic sorting system based on colour is created.
