Multi Height Automatic Filling Station using Programmable Logic Controller

Abstract

Programmable Logic Controllers (PLCs) are used in places where automatic control of the machineries is required. In the industries they are useful to run various tasks without human intervention. One of the advantage is it can work in the harsh environment of the factory floors and have greater immunity to noise and vibrations. However, to use a PLC to control the whole process, it needs to be programmed according to the requirement of the process to be controlled. In many industries such as in beverage industries, bottles are required to be filled-up with a pre-determined amount of liquid. Traditional methods of bottle filling involved placing bottles onto a conveyor and filling only one bottle at a time. This method is time consuming and expensive. The system sequence of operation is designed by ladder diagram and the plc programming software. Sensor plays its vital part as an input signal transmitter for the plc in the system. In this project photoelectric sensor used to detect the presence and the volume of the bottle that move along the conveyor belt. The input signal that has been sent from the sensor to the plc has being made as a reference to filled up the bottle. The entire system is more flexible and time saving.
