Embodiment 1

[0041] (Example 1) figure 1 and even Figure 7 Embodiment 1 of the yarn winding device (automatic winder) according to the present invention is shown. Such as figure 1 As shown, the yarn winding device 1 has a vertically long box-shaped main body frame 2 . On the left side of the main body frame 2, along the yarn traveling path of the yarn Y extending from below to above, a bobbin supporting section 3, an unwinding assisting device 4, a tension applying section 5, a tension sensor 6, and a yarn Y are disposed. A yarn splicing device 7, a slub catcher 8, a winding unit 9, and the like form a package P capable of winding the yarn Y of the yarn supplying bobbin B supported by the bobbin supporting unit 3. Among them, in addition to the tension device 10, the tension imparting unit 5 is provided with a fluff removing device 11 which is a characteristic part of the present invention.

[0042] The unwinding assisting device 4 suppresses an increase in unwinding tension due to a ...

Embodiment 2

[0067] (Example 2) Figure 8 (a) and (b) show a pair of pressing bodies 85 and 86 concerning Example 2 of this invention. Each of the pressing bodies 85, 86 has a circular plate-shaped portion when viewed from the opposing surface side (the side in contact with the yarn), and the plate-shaped portion of one of the pressing bodies 85 is a first plate. The member 87 and the plate-shaped portion of the other pressing body 86 serve as a second plate member 88 . In addition, pressing portions (pressing members) 89 , 90 are formed in annular shapes and positioned to face each other along the peripheral edges of the faces facing each other. Yarn contact portions 91 , 92 that come into contact with the yarn to press the yarn are formed on the opposing surface sides of the pressing portions 89 , 90 . Each of the yarn contact portions 91, 92 is constituted by a convex portion having an arc-shaped cross-sectional shape after cutting the pressing bodies 85, 86 in the radial direction. ...

Embodiment 3

[0069] (Example 3) Figure 9 (a) and (b) show a pair of pressing bodies 93 and 94 concerning Example 3 of this invention. In this third embodiment, one of the pair of pressing bodies 93, 94 has a pressing body 93 having the same structure as the pressing body 85 of the second embodiment, so corresponding parts are given the same reference numerals and descriptions thereof are omitted. The structure of one pressing body 94 is different from that of the second embodiment. That is, although the other pressing body 94 of this Example 3 has the pressing portion (second pressing member) 95 sandwiching the yarn traveling path, the yarn contact portion (second yarn contacting portion) formed on the pressing portion 95 Section) 96 is the plane along the path of yarn travel. Specifically, the end face of the pressing portion (second pressing member) 95 sandwiching the yarn traveling path on the side of the yarn contacting portion 96 is chamfered in an arc shape, and the area surrounde...

Abstract

A hairiness reducing device includes multiple pairs of press-contact members arranged along a yarn path of a yarn being wound on the winding unit. Each pair of the press-contact members is formed by a first press-contact member that includes a first yarn contacting portion and a second press-contact member that includes a second yarn contacting portion arranged with the yarn path interposed therebetween. At least one of a set of first press-contact members and a set of second press-contact members includes a moving mechanism for moving one of the sets relative to the other set. The yarn contacting portions retain the yarn by sandwiching the yarn. In each pair of the press-contact members, the first yarn contacting portion is a protrusion arcuate along the yarn path, while the second yarn contacting portion is either a flat surface along the yarn path or a protrusion arcuate along the yarn path.

Description

technical field [0001] The present invention relates to a hairiness removing device that removes hairiness that occurs on the surface of the yarn when the yarn is wound from a yarn supply bobbin to a winding section, and a yarn winding device provided with the hairiness removing device. Background technique [0002] Generally, when a yarn winding device such as an automatic winder is used to wind a yarn from a yarn supply bobbin to form a package, since the yarn drawn from the yarn supply bobbin is in contact with the The yarn guide part, etc. are in contact with each other, so hairiness will inevitably occur on the wound yarn. As a technique for controlling such hairiness, conventionally, for example, a hairiness suppressing device for an automatic winder as described in JP-A-2001-139231 and a device as described in JP-A-2002-348042 are conventionally known. Hairiness control device. [0003] Among them, the hairiness suppressing device described in Japanese Patent Laid-O...
