PLC Tabanlı Uygulamalar: Mill Makinelerinde Oluşacak İş Kazalarının PLC Kullanılarak Önlenmesi

Abstract

In recent years, the use of automation systems has been increasing, and the basis of these automation systems is generally Programmable Logic Controller (PLC) based application. PLC is used for automation in the industry where there are many advanced machines and devices. In industrial automation systems, it is also used Supervisory Control and Data Acquisition (SCADA), Human - Machine Interface (HMI) systems to ensure safe, quality, and fast production by minimizing human errors and intervention. Because of these systems used in the industries, the automation software developed enables 24/7 production with high quality and low cost. Large-scale companies prefer to use automation systems in order to minimize worker labor and error, prevent work accidents, reduce costs, and make high quality and fast production. PLCs are widely used in packaging systems, especially in the food, chemical, tire, automotive industries, as well as in cement plants, ventilation and cooling facilities, and textile factories. These systems, which are widely used in industries, are preferred due to simple programming structure, ease of setup, use and assembly, durable operation in difficult working environments, low failure, low maintenance cost, and low energy consumption. This article presents the usage and application areas of PLC based automation systems. In addition, a case study is presented that Mill machines, commonly found in truck tire manufacturing factories, are secured using PLC and HMI. Input and output cards have been added to these machines to provide security automatically. As a result of the case study, the production is made faster and with higher quality, and employees are provided with a safer environment. In addition, thanks to the developed HMI interface, Mill machines are able to control and monitor malfunctions and safety situations without the need for additional maintenance personnel.
