FIBER PROCESSING EQUIPMENT

Abstract

The design refers to the yarn handling device which avoids mixing low-quality yarn into the winding tube which is the finished product. The machine controller (5) of the twisting machine (1) generates, by calculating, information related to the remaining amount, which is information equal to 30, about the remaining amount of yarn (Y) in the yarn feed tube (Psl). When it is determined that the yarn (Y) in the winding tube (Pw) reaches the predetermined target winding amount, the machine controller (5) performs the finishing process so that the cutting blade of the automatic unwinding shaft (10) is controlled to cut the yarn Y and the winding mechanism (19) is controlled to finish the shaping of the winding tube (Pw). Then, the machine controller (5) performs the replacement process so that the automatic unwinding shaft (10) replaces the winding tube Pw with a new winding spool (Bw).When it is determined that the numerical value of the information related to the remaining amount is not greater than the predetermined value, the machine control unit (5) performs the shaping process to finish shaping, in the winding mechanism (19), the winding tube (Pw3s) (the shaping winding tube is forced to finish) has a smaller amount of yarn (Y) than the target winding amount.
