Abstract (en)

A problem with the conventional art is that in setting a target for a doffing operation, an attempt to reduce burdens on a traveling controlling mechanism of a doffing device may reduce the operational efficiency of winding units. The present invention provides a winding state recognizing means 30b for recognizing the winding length of a package 7 in each of winding units 2 to be longer or shorter, a target setting means 30c for setting the winding unit on which a doffing operation is to be executed by giving top priority to those winding units 2 which have a winding length corresponding to a full package and giving the second priority to winding units 2 with near full packages, and an operation standby means 3Qd for causing a doffing device 3 to stand by without performing a doffing operation after the doffing device 3 reaches the winding unit 2 on which a doffing operation is to be executed and until the package 7 being formed in the winding unit 2 becomes full (Fig. 5A, 5B).
