SEWING MACHINE SENSING DEVICE DEVELOPMENT FOR SMART FACTORY
SEWING MACHINE SENSING DEVICE DEVELOPMENT FOR SMART FACTORY A. Device for checking and indicating the rest of under thread sewing yarn of sewing machine The sewing work can work in a situation where there is no under-thread by mistake. This leads to defective products and economic losses. To solve this problem, there is a need for a device for detecting the remaining amount of under-thread and transmitting it to an operator. Fig. 3 shows the sensing signal configuration for system design to detect the residual under-thread amount and the system configuration diagram to control it by linking it. The orange block shows the status of the warning lights, the PLC, the touch screen, and the main brake, while the blue block indicates each sensor and control signal for control. Each component of the test apparatus for the detection of the residual thread volume consists of the lower part of the sewing machine and the display part. Under-thread residual sensing device was designed and imple...
