Retrofit Design Control System of Bladder Turn Up Tire Assembly Machine Based on Programmable Logic Controller to Improve Machine Performance

Abstract

—The manufacturing production process is constantly being developed along with industrial automation and the industrial revolution 4.0. This paper discusses research conducted at a manufacturing company that makes tires for motorbikes. The process of making a tire includes the following processes, including mixing, topping, extruding, bead wire, tire assembly, spraying, gimlet, and tire curing. In the tire assembly process, there is a machine used in the assembling process for the manufacture of the outer tires. There are 2 types of machines used, namely STU (Spring Turn Up) and BTU (Bladder Turn Up). To improve the machine performance, a BTU (Bladder Turn Up) tire assembly machine was retrofit on the shaft former drive control system using a servo motor. After retrofit the control system based on Programmable Logic Controller (PLC) on the BTU (Bladder Turn Up) tire assembly machine, the green tire production capacity increases. Furthermore, the cycle time has decreased by making a one-loop system during the ply cord setting process. Also, there is no variation in spare parts on the shaft former drive motor to extend the machine lifetime.
