Title:
静止ドラムを備えた給糸装置からの糸解舒の停止を検出する方法
Document Type and Number:
Japanese Patent JP5469530
Kind Code:
B2
Abstract:
In order to detect the stop of the yarn unwinding from a yarn feeder (10) provided with a stationary drum and with a sensor (S3) generating a pulse per each yarn loop unwound from the drum (12), a treshold time interval (MWT, MWT') is continuosly computed, which corresponds to the maximum interval between two successive pulses, above which it should be regarded that an accidental stop of the yarn has occurred. The treshold time interval is updated in real time as a funcion of the yarn-drawing speed. Then the delay (DT, DT') from the last pulse is continuosly measured and compared with the updated treshold time interval (MWT, MWT'). The machine is stopped when the measured delay (DT, DT') overcomes the updated treshold interval (MWT, MWT').
