Description

Automated Sewing System for Clothing and Control Method of Sewing System Equipment Therefor The present invention relates to a garment sewing automation system and a method for controlling sewing system equipment. Sewing is a field that has evolved over a very long period of human history and is an essential process for manufacturing a wide range of products, from basic clothing to bags. Traditionally classified as a handicraft, this sewing process is difficult to automate due to its complex and intricate nature. While recent advancements in automation technology have led to attempts to partially automate fabric processing, including sewing, the industry remains labor-intensive as much of the work still requires human intervention. The automation of the sewing process is a critical task for reducing reliance on human labor and improving productivity. Particularly in light of the global issue of workforce reduction due to an aging population, there is a growing technological need to enhance efficiency in mass production and maintain consistent product quality through the automation of sewing processes. FIG. 1 is an equipment layout diagram of a sewing automation system according to one embodiment of the present invention. Figure 2 is a hardware configuration diagram of the sewing automation system of Figure 1. Figure 3 is a schematic diagram showing the operating range or process area of each device of the sewing automation system of Figure 1. Figure 4 is an exploded perspective view of the sewing jig of Figure 1. FIG. 5 is a perspective view of the end effector of the jig handling unit of FIG. 1. FIGS. 6 to 9 are perspective views illustrating the process of transferring or disassembling a sewing jig using an end effector of a jig handling unit. FIG. 10 is a perspective view of the fabric transfer unit of FIG. 1. FIG. 11 is a perspective view of the turn unit of FIG. 1. FIG. 12 is a perspective view showing the process of feeding fabric into a sewing unit using the turn unit and the feeding assist unit of FIG. 11. FIGS. 13 and FIGS. 14 are perspective views illustrating the sewing process using the turn unit and sewing unit of FIG. 11, respectively. FIG. 15 is a flowchart illustrating a control method for sewing automation system equipment according to one embodiment of the present invention. FIGS. 16 to 19 are schematic diagrams showing the process steps using the sewing automation system of FIG. 1 in sequence.
