Problems solved by technology

In other words, in order to increase the amount of yarn storage, it is necessary to make the yarn storage roller larger, resulting in a larger moment of inertia of the yarn storage roller
In this case, it is difficult to control the rotation of the roller with high sensitivity when ya

Embodiment Construction

[0027] Next, embodiments of the present invention will be described. This embodiment is an example in which the present invention is applied to an automatic winder having a plurality of winding units (yarn winding devices) that wind a yarn from a yarn supplying bobbin. The unwound yarn is formed into a winding package. The automatic winder has a structure in which a plurality of winding units forming one package are arranged along one direction. figure 1 It is a side view of a winding unit of the automatic winder.

[0028] Such as figure 1 As shown, each winding unit 1 has a bobbin supply device 2, a yarn feeding part 3, and a package winding part 4, and also has a unit control part 5 for controlling each part of the winding unit 1. In addition, the winding unit 1 holds the yarn supplying bobbin 8 supplied from the bobbin supplying device 2 by the yarn supplying section 3, and while unwound the spun yarn from the yarn supplying bobbin 8 by the package winding section 4, Wh...

Abstract

The invention provides a yarn accumulating device and yarn winding device provided with the same and aims to reduce a weight of a yarn accumulating roller and realize a quick rotational control of the yarn accumulating roller. A winding unit (2) includes a yarn supplying section (3), a package winding section (4), and a yarn accumulating device (22) arranged between the yarn supplying section (3) and the package winding section (4). The yarn accumulating device (22) includes a cylindrical yarn accumulating roller (40) around which a yarn (y) is wound by being rotated. The yarn accumulating roller (40) is formed of a resin material which is a non-metal material.

Description

technical field [0001] The present invention relates to a yarn accumulating device for accumulating a yarn, and a yarn winding device provided with the yarn accumulating device. Background technique [0002] International Publication No. 2011 / 040545 discloses an automatic winder (winder) that winds the yarn to form a package while removing yarn defects such as slubs of the yarn unwound from the yarn feeding bobbin. ). The automatic winder of Patent Document 1 includes various devices such as a yarn splicing device and a yarn accumulating device between the yarn supplying bobbin and the package winding section for winding the yarn. The yarn splicing device is used to splice the yarn on the package side and the yarn on the yarn feeding bobbin side when changing the yarn feeding bobbin, when removing yarn defects and cutting the yarn, or when the yarn is suddenly broken stand up. In addition, the yarn accumulating device has a rotating yarn accumulating roller (rotary accumu...
