Embodiment Construction

[0038] Hereinafter, embodiments of the present invention will be described with reference to the drawings. In addition, "upstream" and "downstream" in this specification refer to upstream and downstream in the moving direction of the yarn at the time of yarn winding.

[0039] Such as figure 1 As shown, the automatic winder (yarn winding machine) 1 has: a plurality of yarn winding units 10 arranged side by side, a doffing device (winding tube supply device, bundle yarn winding device) 60, a machine control Device 90.

[0040] Each yarn winding unit 10 winds the yarn 20 unwound from the yarn supplying bobbin 21 on the winding bobbin supported by the cradle (winding bobbin supporting part) 23 while traversing (traversing). 22 to form a package 30.

[0041]The doffing device 60 moves to the position of the yarn winding unit 10 when the package 30 in each yarn winding unit 10 becomes fully wound, detaches the fully wound package 30, and supplies the package 30 not wound with th...

Abstract

A yarn winding unit includes a winding section that winds a yarn around a winding tube to form a package, and a control section that controls the winding section. The winding section includes a winding tube supporting section that supports the winding tube, a contact roller that rotates in contact with the winding tube or the package, and a traversing device that is arranged independently of the contact roller and that traverses the yarn that is to be wound around the winding tube. The control section controls the winding section such that the traversing speed of the traversing device is maintained equal to or below a predetermined speed when the winding of the yarn is started.

Description

technical field [0001] The present invention relates to a yarn winding unit that winds a yarn while traversing it to form a package. Background technique [0002] Conventionally, there is known a yarn winding machine in which a winding tube is rotatably supported by a cradle, and a yarn is wound while traversing the outer peripheral surface of the winding tube to form a package. Such a yarn winding machine has, for example, a configuration for traversing the yarn: a traverse guide that engages the yarn and traverses the yarn; and a traverse drive unit that drives the traverse guide. . [0003] Japanese Patent Application Laid-Open No. 2009-227412 discloses a structure in which a traverse drive unit is controlled to change the traverse width of the traverse device. Specifically, the yarn winding machine narrows the traverse width when accelerating the rotation speed (winding speed) of the package, and widens the traverse width (makes the The traverse width is a constant va...
