Design and Implementation of Automated Painting Line Using Programmable Logic Controller

Abstract

In the late sixties of the last century the American company general electric developed the programmable logic controllers (PLC) as an alternative to the complex relay control system in order to use it in its car production lines. These controllers showed very high efficiency in control systems and higher reliability in protecting the components being controlled. In addition to this, the latter improved characteristics made PLCs the most control system used in production Processes. The aim of this project is to illustrate the usage of PLC in automation of production lines and the utilization of its high capabilities to process input signals from several sensors. This is done by implementing a control system to paint the product through production line as an application in YARMOUK industry complex. Here several processes work in a sequential fashion, in this stage PLCs are used to maintain this sequence. Where a device was used by the Siemens company for logical controllers and was programmed by ladder programming language for the implementation of orders where this controller controls a set of motors in addition to an antenna system in a sequence which adds to the system efficiency, reliability and high production speed and these three interlocutors are considered one of the most important reasons that led to automation This production line in addition to the causes of health damage to which the worker is exposed during manual painting on a daily basis. This automation led to increase in quantity of products exceed 100% and reducing the number of worker to 30% and led to higher quality product.
