Embodiment Construction

[0027] Next, embodiments of the invention will be described. First, refer to figure 1 The overall structure of the automatic winder 1 of this embodiment will be described. However, in this specification, "upstream" and "downstream" mean upstream and downstream in the traveling direction of the yarn at the time of yarn winding. Such as figure 2 etc., in this embodiment, since the yarn 20 unwound from the yarn supplying bobbin 21 in the yarn supplying section 16 is wound up by the winding section 17, the side of the yarn supplying section 16 is upstream, and the yarn supplying section 16 side is upstream. The take part 17 side is downstream.

[0028] Such as figure 1 As shown, an automatic winder (yarn winding machine) 1 includes a plurality of winding units (winding units) 10 arranged in parallel, an automatic doffing device 8 (automatic doffing device), and a machine control device (machine control device). 90.

[0029] Each winding unit 10 can form a package 30 by wind...

Abstract

A cradle includes a cradle main body, a larger-diameter side bobbin holding section, and a rotation preventing section. The larger-diameter side bobbin holding section is rotatably mounted on the cradle main body and adapted to hold a winding bobbin around which a yarn is wound. The larger-diameter side bobbin holding section includes a base member (70) and a contact member. The base member (70) is rotatably mounted on the cradle main body. The contact member is detachably mounted to the base member (70) by at least a portion of the contact member being elastically deformed, and adapted to hold the winding bobbin by making contact with the winding bobbin. The rotation preventing section is adapted to present relative rotation of the contact member with respect to the base member (70).

Description

technical field [0001] The present invention relates to cradles for holding coiled tubes. Background technique [0002] Conventionally, there is known a yarn winding machine that forms a package by winding a yarn around a winding tube (winding bobbin) held by a cradle. As a structure for the cradle to hold the take-up tube, for example, a structure is known in which two bobbin holding parts contacting the inner wall surface of the take-up tube are provided, and the two ends of the take-up tube are clamped by the bobbin holding parts, and the This holds the coiled tube. Japanese Unexamined Patent Publication No. 2006-321615 (Patent Document 1) discloses a yarn winding machine including such a cradle. [0003] The yarn winding machine of Patent Document 1 includes a motor for driving the winding bobbin in the vicinity of one bobbin holding portion (bobbin holder). The bobbin holder is attached to the drive shaft of the motor so as to rotate integrally with the drive shaft. ...
