Problems solved by technology

Therefore, since the time required for the judgment process increases, the travel control to the travel target becomes difficult
Or, the cost of the control mechanism required to control the travel of the doffing device increases
On the other hand, if the travel control method of Patent Document 1 is not used, and the doffing device is controlled to travel to the full spindle only when a full spindle occurs, the efficiency of the doffing operation will be reduced.
And also incur low working efficiency of the winding unit

Embodiment Construction

[0034] Embodiments of the present invention will be described below with reference to the drawings.

[0035] Next, a winder 1 according to an embodiment of the present invention will be described with reference to FIG. 1 .

[0036] The winder 1 is a device that unwinds a yarn supplying bobbin 6 that is a package of raw material yarn to form a package 7 .

[0037] This winder 1 has a plurality of winding units 2 arranged side by side in one direction, a doffing device 3 freely movable along the row of winding units 2 , and an air supply unit 4 arranged at one end side of the row of winding units 2 . And the main body control part 5.

[0038] Here, the winding unit 2 refers to a unit (assembly of devices) for forming one package 7 on one winding drum 10 . The winder 1 can form packages 7 in parallel corresponding to the number of winding units 2 arranged in the winder 1 .

[0039] In addition, the doffing device 3 is a device that moves to any of the above-mentioned winding u...

Abstract

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.

Description

technical field [0001] The present invention relates to a textile machine with a doffing device, which has a plurality of winding units for winding a yarn to form a package on a winding drum, and stops at a working position provided in each of the above winding units to correspond to the The above-mentioned winding unit corresponding to the working position is a doffing device for performing doffing operations. Background technique [0002] Conventionally, a textile machine is known that includes a plurality of winding units arranged in a row, and a doffing device that travels along the row of the winding units and performs a doffing operation on the winding units. [0003] Patent Document 1 discloses a textile machine (winder) in which a full bobbin (winding unit when the package becomes full) is found, the doffing operation is efficiently performed by the doffer, and the movement of the doffer is controlled. method. [0004] Here, although the time when each winding unit...
