Problems solved by technology

However, in the case where the traverse detectors are provided at the left and right ends of the package center, the yarn cannot be detected when the traverse width is changed, so adjustments must be made according to changes in the traverse width. Problems with the position of the traverse detection unit

Embodiment Construction

[0041] Next, embodiments of the invention will be described with reference to the drawings.

[0042] use Figure 1 to Figure 6 The yarn winding device 100 according to the first embodiment of the present invention will be described.

[0043] like figure 1 As shown, the yarn winding device 100 of this embodiment is a yarn winding device that winds the yarn Y of the yarn supply bobbin 81 while being traversed (reciprocating) by the traverse device 12. Yarn layers are formed on tube 82 and package 83 is formed. The moving direction of the yarn Y is the direction from the yarn supply bobbin 81 toward the package 83 . Although figure 1 One yarn winding device 100 is shown, but an automatic winder is configured by arranging a plurality of such yarn winding devices 100 in a row.

[0044] In this specification, the winding bobbin 82 and the package 83 are collectively referred to as the winding bobbin B. That is, the winding bobbin B on which the yarn layer is not formed is the ...

Abstract

A yarn winding device (100) includes a winding section (200) for winding a package (83); a traverse guide (17), driven independent from drive of the package (83), for traversing a yarn Y to be wound into the package (83); and a traverse detection section (70), arranged at a central part of a traverse width of the traverse guide (17), for detecting presence or absence of the yarn Y.

Description

technical field [0001] The present invention relates to the technology of a yarn winding device for winding yarn into a package. More specifically, it relates to a technique for detecting a defect in traverse of a yarn winding device. Background technique [0002] In the yarn winding device, there is a problem that a defective package with poor shape and unwinding property is formed due to poor traverse of the yarn. A conventional yarn winding device is provided with a traverse detection unit that detects a yarn traverse defect. For example, in a drum traverse type yarn winding device, a traverse detection unit is provided only at one of the left and right ends relative to the center portion of the package (for example, refer to JP-A-63-17773). [0003] The traversing defect in the drum traversing type yarn winding device is basically one of the following situations: (1) The yarn is not traversed to both ends of the drum but only traversed in the center of the drum. (2) I...
