Design of Liquid Filling System Using Programmable Logic Controller

Abstract

Traditional methods of filling the different types of liquids into the bottles involve manual handling which consumes time, increases the production cost and lack the quality of the product due to human errors. This project is based on industrial automation and is a vast application used in many industries like milk industries, chemical, food, mineral water, and other industries. The work provides a lot of benefits like low power consumption, low operational cost, less maintenance, accuracy and many more. The filling of the bottles is controlled by using a controller known as programmable logic controller (PLC) which is also the heart of the entire system. A prototype has been designed to illustrate the project. For the conveyor system, a dc motor has been selected for better performance and ease of operation. A sensor has been used to detect the position of the bottle. In the project, less number of systems and components used hence, the overall cost has been reduced to an extent. Ladder logic has been used for the programming of the PLC, which is the most widely used language for the programming of the PLC.
