Embodiment Construction

[0045] Next, embodiments of the present invention will be described. figure 1 It is a schematic side view of the winder unit (yarn winding machine) 2 included in the automatic winder according to the embodiment of the present invention. In the automatic winder mechanism of this embodiment, a plurality of winder units 2 are arranged side by side. In addition, this automatic winder is provided with an unillustrated machine management device for collectively managing the above-mentioned winder unit 2 .

[0046] The winder unit 2 includes a control unit 25 . The control unit 25 is composed of hardware such as a CPU, ROM, and RAM (not shown), and software such as a control program stored in the RAM. In addition, each component of the winder unit 2 is controlled by cooperation of the aforementioned hardware and software. In addition, the control unit 25 may be provided in the organism management device.

[0047] Each control unit 25 is configured to be able to communicate with t...

Abstract

The invention provides a yarn winding machine and a yarn winding method. The yarn supply unit (7) supplies the yarn (20). The yarn storage unit (18) stores the yarn (20) supplied from the yarn supply unit (7). The winding unit (8) winds the yarn (20) stored in the yarn storage unit (18) to form a package (30). The upper limit sensor (36) detects whether the accumulated amount of the yarn (20) in the yarn accumulation part (18) is equal to or greater than a predetermined upper limit. The drum drive motor (19) adjusts the speed of the yarn (20) coming out of the yarn pool (18). The control unit (25) adjusts the speed of the yarn (20) by the drum drive motor (19) within a predetermined adjustment range, thereby performing pooled amount control for controlling the aforementioned pooled amount. Further, the control unit (25) performs adjustment width narrowing control for narrowing the adjustment width to a target value in parallel with the pooled amount control based on information detected by the upper limit sensor (36).

Description

technical field [0001] The present invention relates to a yarn winding machine provided with a yarn accumulating portion. Specifically, it relates to the control of the storage amount of the yarn storage unit. Background technique [0002] Japanese Patent Application Laid-Open No. 2012-197135 discloses a yarn winding machine having a configuration in which a yarn accumulating section (reservoir) is disposed between a yarn supplying section and a winding section. The yarn accumulating section is configured to temporarily store the yarn supplied from the yarn supplying section by winding it up. The winding section draws out and winds the yarn accumulated in the yarn accumulating section to form a package. In this way, by interposing the yarn accumulating section between the yarn supplying section and the winding section, the yarn can be continuously unwound at a desired unwinding yarn speed during winding of the yarn, and the yarn can be improved. Coiling productivity of wi...
