Embodiment Construction

[0024] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings. In addition, in each figure, the same or equivalent parts are given the same reference numerals, and repeated descriptions are omitted.

[0025] [Structure of winding unit] such as figure 1 As shown, the winding unit 1 winds the yarn Y from the yarn supply bobbin B to the package P. The yarn supply bobbin B is formed by the spinning frame in the previous process, and is transported from the spinning frame in a state of being placed on a tray, for example. In addition, an automatic winder as a textile machine is constructed by arranging a plurality of winding units 1 in parallel.

[0026] The winding unit 1 is provided with a bobbin support part (yarn feeding part) 2, a yarn unwinding auxiliary device 3, a pre-clearer 4, and a tension in order from the upstream side (here, the lower side) along the traveling path of the yarn Y. The application device 5, th...

Abstract

The splicing nozzle structure (100) of the present invention is provided with a twisting nozzle (110) formed with a splicing chamber (113) for splicing by the action of compressed air, and a housing part (121) formed with accommodating the twisting nozzle (110). The twisting nozzle support body (120). The splicing nozzle structure (100) has a splicing chamber (113) for passing from the twisting nozzle support (120) to the twisting nozzle (110) through the twisting nozzle support (120) and the twisting nozzle (110). ) provides an air flow path (151) for compressed air. The twisting nozzle (110) is attached to the twisting nozzle support (120) via an O-ring (130) surrounding the air flow path (151).

Description

Technical field [0001] The invention relates to a twisting nozzle, a splicing nozzle structure, a splicing device, a winding unit and a fiber machine. Background technique [0002] As a conventional jointing nozzle structure, we know, for example, Japanese Patent Laid-Open No. 59-228029 and Japanese Patent Laid-Open No. 2010-30707: a twisting nozzle with a piecing chamber formed by the action of compressed air. And the structure of the twisting nozzle support body that forms the accommodating portion of the twisting nozzle. [0003] Among them, in the splicing nozzle structure as described above, the attachment of the twisting nozzle to the twisting nozzle support is usually achieved by bonding using an adhesive. However, when the twisting nozzle is attached to the twisting nozzle support by bonding in this way, there is a concern that the work, labor, and quality of the attachment may be uneven. In addition, in this case, for example, when the twisting nozzle is maintained or da...
