Embodiment Construction

[0038] Next, a spinning frame (yarn winding machine) according to an embodiment of the present invention will be described with reference to the drawings. In this specification, "upstream" and "downstream" mean upstream and downstream in the moving direction of the yarn during spinning.

[0039] figure 1 The illustrated spinning frame 1 serving as a yarn winding machine includes a plurality of winding units 2 , a piecing cart 3 , a doffing cart (doffer) 4 , a blower 93 , and a prime mover box 5 arranged in parallel.

[0040] The prime mover case 5 includes a body control device (control unit) 30 . The body control device 30 controls the plurality of winding units 2 . The body control device 30 includes a color liquid crystal monitor 31 and an input unit 32 . If the operator performs appropriate operations, the color liquid crystal monitor 31 displays information related to the operating status of each winding unit 2 and / or yarn quality. The input unit 32 includes a plurali...

Abstract

A yarn winding machine (1) includes a plurality of winding units (2) and a control section (30). Each of the plurality of winding units (2) winds a package (45). The control section (30) controls the plurality of the winding units (2). The control section performs a control to calculate a winding-end expected time of the package in each of the winding units. The control section performs a control to store a produced quantity indicating a quantity of the package of which winding has been completed, and when a difference between the produced quantity and an expected production quantity is equal to or less than a predetermined value, to determine whether or not to supply a new bobbin (48) to the winding units in accordance with the winding-end expected time.

Description

technical field [0001] The present invention relates to a yarn winding machine in which packages are individually wound by a plurality of winding units. Background technique [0002] Conventionally, a yarn winding machine including a doffing device for discharging a fully wound package or the like is known. Japanese Patent Application Publication No. 8-109527 (Patent Document 1), Japanese Patent Application Publication No. 63-92577 (Patent Document 2), and Japanese Patent Application Publication No. 2011-162351 (Patent Document 3) disclose a doffing yarn The yarn winding machine of the device. [0003] Patent Document 1 discloses control for efficiently operating a doffing device (doffing cart). In the yarn winding machine of Patent Document 1, the timing at which the package becomes full is predicted for each winding unit (spinning machine), and based on the predicted information, for example, the winding time immediately before the package is fully wound is determined. ...
