Embodiment Construction

[0027] 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.

[0028] Such as figure 1 As shown, the spinning machine 1 has a plurality of spinning units 2 , a yarn joining trolley 3 , a blowing box 4 and a prime mover box 5 . A plurality of spinning units 2 are arranged in a row. Each spinning unit 2 produces a spun yarn Y and winds it into a package P. The yarn joining cart 3 performs a yarn joining operation in the spinning unit 2 in which the spun yarn Y is cut. An air supply source and the like for generating suction flow, swirl flow, and the like in each part of the spinning unit 2 are accommodated in the blow box 4 . A prime mover and the like for supplying power to each part of the spinning unit 2 are housed in the prime mover case 5 .

Abstract

A spinning unit includes a drafting device and a spinning device that supply a spun yarn, a winding device that winds the spun yarn to form a package, and a yarn pooling device that pools the spun yarn between a yarn supplying device and the winding device. The yarn pooling device includes a yarn pooling roller (51) around which the spun yarn is wound, and a first regulating portion (72). The first regulating portion (72) is arranged facing a base end section (52a) on a winding start side of a yarn pooling section (52) where the spun yarn is wound around the yarn pooling roller (51), and regulates a movement of an end of the spun yarn that sways about on the base end section (52a) side when a breakage of the spun yarn occurs on the spinning device side, such that the swaying end of the spun yarn is prevented from moving to a tip end section (52b) of the yarn pooling section (52) before the spun yarn is orderly unwound from the tip end section (52b) side.

Description

technical field [0001] The present invention relates to a spinning unit that generates spun yarn and winds the spun yarn into a package, and a spinning machine having a plurality of such spinning units. Background technique [0002] The currently known spinning unit has: a yarn feeding device that supplies the spun yarn; a winding device that winds the spun yarn on a package; A yarn accumulating device for accumulating a spun yarn by winding a yarn around a yarn accumulating roller (for example, refer to JP-A-2010-174421). [0003] In the above-mentioned spinning unit, when the spun yarn is cut, if the yarn end of the spun yarn moves to a part other than the predetermined one in the yarn accumulating roller, it may affect the subsequent spinning. The smooth movement of the unit gets in the way. Contents of the invention [0004] An object of the present invention is to provide a spinning unit capable of controlling the movement of the yarn end of the spun yarn when the s...
