Sistem Otomasi Loading/Unloading pada Proses Annealing Furnace Berbasis Plc

Abstract

In the process of handling in annealing furnace, loading and unloading system is a very important activity to help the process of moving the workpiece into annealing process. Thus this work is done repeatedly throughout the work day. Previously loading and unloading jobs are still done entirely by the workers manually, without any mechanical aids, more effective and lower operating costs. But behind those advantages, poorly designed manual work will pose a high risk of working injuries, especially injuries to the lower spine that can be fatal to the worker. Therefore, PLC as a controller helps an activity to be faster and easier. And this PLC is a digital computer device used to automate a machine or manage electro-mechanical processes in an industry. Then the system is auto loading with the help of cylinder and timer make the process of loading have spare time for 18 minutes for operator to do other work and will not standby continue. On the other hand the system of unloading and cooling is auto and assisted by cylinder can also directly to cooling process without taking and putting to cooling rack and can cut cooling time from 60 minutes to 8 minutes. And the auto system in unloading is more effective 86% than before.
