Embodiment Construction

[0030] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings. In addition, in each figure, the same reference numerals are assigned to the same or corresponding parts, and overlapping descriptions will be omitted.

[0031] Such as figure 1 As shown, the winding unit 1 winds the yarn Y from the yarn supplying bobbin B to the package P. The yarn supplying bobbin B is formed by the previous spinning frame, and is transported from the spinning frame in a state of being set on a pallet, for example. In addition, a plurality of winding units 1 are arranged side by side to constitute an automatic winder which is a textile machine.

[0032]In the winding unit 1, along the moving path of the yarn Y, that is, the yarn path is provided in the following order from the upstream side (here, the lower side): a bobbin supporting part (yarn feeding part) 2, a yarn unwinding auxiliary device 3, Pre-clearer 4, door-type tensione...

Abstract

The invention provides a yarn jointing device, a method of jointing yarn, a winding unit comprising the yarn jointing device, and a textile machine, wherein the yarn jointing device is capable of adjuating the length of a yarn end being dragged into an untwisting unit with high precision. The yarn jointing device has a first gripping unit (60A) which is used for taking a yarn end (YA) at one side, a first cutting unit which serves to cut off the yarn end (YA) at one side, a first untwisting unit which serves the yarn end (YA) at a cut off side, a first displacement unit which serves a first gripping position (69A) of the yarn end (YA) at one end to move, so as to adjust the length of a yarn end (YA) being dragged into an untwisting unit, a second gripping unit which is used for taking a yarn end at the other side, a second cutting unit which serves to cut off the yarn end at the other side, a second untwisting unit which serves the yarn end at the other side opposite to the cut off side, a second displacement unit which serves the second gripping position of the yarn end (YA) at the other end to move, so as to adjust the length of a yarn end at the other side opposite to the side being dragged into the untwisting unit, and a yarn jointing unit which is used for twisting the yarn end (YA) being untwisted and the yarn end at the other side.

Description

technical field [0001] The invention relates to a yarn joining device, a winding unit, a fiber machine and a yarn joining method. Background technique [0002] In a yarn splicing device mounted on a textile machine such as an automatic winder, it is important to adjust the untwisted length of the yarn end as an element for achieving appropriate yarn splicing regardless of the type of yarn. For example, Chinese Patent Application Publication No. 101165241 describes a technique for adjusting the length of the yarn end pulled into the untwisting section by using a guide member that bends the yarn. [0003] However, in the technology described in Chinese Patent Application Publication No. 101165241 specification, due to the tension of the yarn bent by the guide member, the length of the yarn end changes, so it may not be possible to adjust the pull-in to untwisting with high precision. The length of the yarn end of the section. Contents of the invention [0004] Therefore, a...
