Research and Improvement of the Electronic Control System for Garment Extraction Machines in the Industrial Sewing Sector

Abstract

The cutting process in clothing production is highly demanding, traditionally requiring significant skill and craftsmanship from workers. Historically, this step depended heavily on individual expertise, where manual precision greatly influenced the quality and consistency of garments. However, technological advancements, especially the introduction of industrial cutting machines, have substantially reduced reliance on manual labor. Nevertheless, certain older-generation machines equipped with microprocessor-controlled systems still exhibit significant drawbacks. Common issues include difficulties maintaining precise control of the X and Y axes and challenges in effectively managing the main spindle motor. Additionally, these outdated systems often fail to swiftly detect operational errors, leading to increased downtime and reduced efficiency. This article addresses these challenges by presenting research focused on improving the control system through the integration of the Mitsubishi FX3U–48MT PLC into the Durkopp Artler 743-121 extraction machine. Experimental results indicate that this upgraded control system significantly enhances machine performance, complemented by an intuitive HMI interface that simplifies monitoring and troubleshooting. Consequently, this modernization approach improves energy efficiency, boosts labor productivity, and has been successfully implemented in several garment factories in Vietnam.
