概要:

Drawing-in process on covering machines is so difficult and inefficient that its automation is especially hoped. However the automatic drawing-in system developed in order to improve drawing-in operation is not able to distinguish whether the core yarn is successfully drawn into the hollow spindle or not. So we developed a detecting system for fine Spandex, applying pressure variation in pipe flow caused by yarn behavior. Results obtained are as follows : (1) … Pressure variation can check the presence of Spandex when it runs through, a small air flow pipe. (2) This detecting system consists of a diaphragm type pressure sensor, a small pipe and a simple sequence program. (3) The system can detect Spandex yarns from 30D to 420D that are widely used and too thin to sense even by manual operation. And it is confirmed that the system has practical utility. (4) The system is installed on the automatic yarn drawing-in device. When the system distinguish the failure to draw Spandex into hollow spindles, the failed Spandex package is removed and drawing-in is again attempted with another package on the same spindle. In this way, yarn drawing-in is performed for all spindles on a covering machine continually and automatically. 続きを見る
