AI Technical Summary

Problems solved by technology

However, due to the difference in the winding amount of the yarn in the package, the diameter of the package at the time of yarn cutting is different, and there is a problem that it is difficult to stabilize the positional relationship between the catching part and the yarn in the state where the yarn is released.

Embodiment Construction

[0021] Preferred embodiments of the yarn winding machine of the present invention will be described in detail below with reference to the drawings. In the description of the drawings, the same reference numerals are attached to the same or corresponding elements, and overlapping descriptions are omitted.

[0022] refer to figure 1 The overall structure of the automatic winding machine 1 including the winding unit (yarn winding machine) 10 of this embodiment will be described. "Upstream" and "downstream" in this specification mean upstream and downstream in the yarn running direction when the yarn is wound.

[0023] Such as figure 1 As shown, the automatic winding machine 1 is provided with a plurality of winding units 10 arranged in a row, an automatic doffing device 80 and a body setting device 90 .

[0024] Each winding unit 10 is configured to wind the yarn 20 unwound from the yarn supplying bobbin 21 while traversing to form a package 30 .

[0025] The automatic doffin...

Abstract

The invention provides a yarn winding machine. Wherein, the winding unit (10) releases the contact state between the package (30) and the contact roller (29) when the upper yarn catching part (26) starts to move from the catching area (R1) to the splicing area (R3). Therefore, even if the upper yarn catching member (26) catches the double thread in the middle part of the yarn (20), it can prevent the yarn (20) from being cut between the package (30) and the contact roller (29), It is possible to prevent the yarn end (30a) from being mixed into the package (30) as a broken yarn. Since the contact state between the package (30) and the contact roller (29) is not released when the upper yarn catching part (26) is located in the catching area (R1), the position of the upper yarn catching part (26) and the yarn end (30a) The relationship is stable, and the yarn end (30a) can be caught firmly.

Description

technical field [0001] The present invention relates to yarn winding machines. Background technique [0002] As a conventional yarn winding machine, there is, for example, the yarn winding machine described in JP-A-2003-261265. The yarn winding machine includes a touch roller that contacts a package on which the yarn is wound, and a catcher that sucks and catches the yarn from the package when the yarn is cut. In this conventional yarn winding machine, the package is rotated in the reverse winding direction when the yarn is cut, and the catching part is brought close to the package to catch the yarn. After the yarn connected to the package is caught by the catching part, the caught yarn is guided to the splicing part and joined to the yarn on the side of the yarn supplying bobbin. [0003] In the above-mentioned yarn winding machine, a phenomenon in which the catching part catches the middle part of the yarn (hereinafter referred to as "double thread") may occur. In the c...
