Automation Control Design of An Storage Machine Based on Omron PLC System

Industrial control is usually choosing Programmable Logic Controller (PLC) as a system. An automotive manufacturing company that produces pistons as the main product has always made continuous improvements in the control process. This paper discusses one of our improvement that focuses on the storage system with the PLC controller. In this system, there is currently a line that can only accommodate the storage of a box in a cycle. That is not an effective process. The leg time on operator box's replacing can be avoided by storage more than a box in a cycle. The ineffectiveness also occurs on autoloading in this storage system because there is still a problem that the piston falls into an incorrect position. The problem comes from an electric motor on the piston placement to the container box. The authors made improvements in the control system design of a storage automation machine that aims to make the automation machine accommodate three boxes in a cycle and replace the motor in the autoloader process with a servo motor technology so that the piston falls into the correct position. The application of this design has the target to increase production efficiency by 2.5% of the total piston production in the storage automation machine.
