SEWING MACHINE SENSING DEVICE DEVELOPMENT FOR SMART FACTORY<\/strong> <\/a><\/h2>\n\n\n\n

<\/strong>A. Device for checking and indicating the rest of underthread 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. 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.<\/p>\n\n\n\n

 Software algorithms were designed to implement\nthe logic sequence so that if the under-thread is insufficient, the operation\nstops immediately.<\/p>\n\n\n\n

\u00a0The configuration of under-thread residual sensing and display system. 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 implemented as primary and secondary sensing parts. https:\/\/vssewingmachine.in\/merit-tailoring-machine-price-list-in-chennai\/ <\/a>The primary sensing uses a cylinder (CXSM630) for the bobbin and a SMAT-8M sensor for the FESTO position transmitter.[9] The system is implemented so that the remaining amount of the bottom thread can be calculated by the data that the cylinder pin advances and senses the distance gap.<\/p>\n\n\n\n

 Secondary detection shows the sensing\nprinciple to detect and warn the bobbin rotation state while reducing the\ndefect caused by the bobbin not rotating when the bobbin is tangled or\ndefective. To check the bobbin rotation status, the Omron NPN type photo sensor\n(E3Z-LL61) checks the rotation of the bobbin with four pairs of black and white\nstickers at 45 degrees on the bobbin.<\/p>\n\n\n\n

 B. Stitch control device and sewing thread\ninformation detection system concept configuration In order to make smart\nfactory of sewing factory, it is necessary to prevent worker\u2019s mistakes and to\nrecord and confirm the current work. The position where the residual\nunder-thread detection device and the stitch automatic control device are to be\nattached in the sewing machine being used in the sewing factory. In order to\nautomatically adjust the stitches, the information about the fabric currently\nbeing worked on is entered in advance, so that the number of stitches can be\nautomatically adjusted.<\/p>\n\n\n\n

 Detailed data and method of monitoring system\nat the upper left part of the figure are explained below. C. Information flow\nof the sewing machine detected from sensors for smart sewing process the flow\nof information obtained from the parts(under-thread residual detection device,\nautomatic stitch control device, monitoring system) developed for the sewing process\nsmartization. The collected information is displayed in the monitoring system,\nand it is transmitted to the POP system, the PDM system and the final\ncustomer-linked system, so that the sewing process can be made smart.[10-11]<\/p>\n\n\n\n

 It is a study to apply smart factory to the\ntextile industry in this research and development. A study on the smartization\nof sewing process among several textile streams was conducted.[12-13] In order\nto make the sewing machine smart, we applied the same sewing machine which is\nused in the present industrial field and modified the sewing machine. First,\nthe residual amount of the under-thread was detected to reduce the worker\u2019s\nmistake and product defect. Secondly, in the sewing industry where workers are\naging, it is possible to control the automatic stitch number according to the\nproduct type. Next, monitoring of the overall sewing process requires further\nwork on the presser foot pressure control, tension control, POP(point of\nproduction) system and all monitoring data interlocks.<\/p>\n","protected":false},"excerpt":{"rendered":"
