광센서를 이용한 로터리 보빈용 단채널 밑실 감지기 개발에 관한 연구

We develop a single-channel thread sensor for rotary bobbin by optical sensing and analyze the signal characteristics. A specially designed mount made of ABS(acrylonitrile-butadiene-styrene) resin encapsulating an optical sensor was fabricated by using a 3D printer and attached to the rotary bobbin system. Changes on sensing signals of different states of the thread in weaving operation was monitored and analyzed by a newly developed algorithm. The sensor effectively detects an unintentional thread cut and run-out during weaving. By using our sensor system, it is possible to stop the weaving machine promptly minimizing the loss of expensive fabrics.
