Embodiment Construction

[0038] use figure 1 A spinning machine 100 including a plurality of spinning units 1 according to an embodiment of the present invention will be described. In the spinning machine 100, a plurality of spinning units 1 for producing a spun yarn Y from a fiber bundle (hereinafter referred to as "sliver") F are arranged in parallel. The spinning machine 100 includes a piecing cart 11 , a driving device, a control device, and the like, which are not shown in the drawings.

[0039] In order to improve the quality of the spun yarn Y produced by the spinning machine 100, it is required that the spun yarn Y produced by one spinning unit 1 can stably ensure a certain quality. It is required that each spun yarn Y produced by each spinning unit 1 can uniformly ensure a certain quality.

[0040] Therefore, the spinning machine 100 confirms that the standard deviation of the yarn thickness of the spun yarn Y produced by one spinning unit 1 satisfies a predetermined standard. Then, the sp...

Abstract

The invention provides a spinning unit, wherein a drawing-off spinning unit (1) comprises a drawing-off device (5), a spinning device (6), a tension stabilizing device (8), a winding device (9) and a yarn defect detecting device (7).The drawing-off device (5) drafts a fibre bundle (F).The spinning device (6) produces spinnings (Y) from the fibre bundle (F) drafted by the drawing-off device (5).The tension stabilizing device (8) stabilizes the tension of the spinnings (Y) produced by the spinning device (6).The winding device (9) winds a package (91) of the spinnings (Y) fed from the tension stabilizing device (8).The yarn defect detecting device (7) can detect a yarn defect in the spinnings (Y).The yarn defect detecting device (7) is arranged between the spinning device (6) and the tension stabilizing device (8).

Description

technical field [0001] The present invention relates to the technology of spinning unit (SPINNING UNIT). More specifically, it relates to a technology of a spinning unit capable of detecting a yarn defect generated during spinning with high precision. Background technique [0002] A conventionally known spinning unit produces a spun yarn by twisting a drawn fiber bundle, and winds the spun yarn with a winding device to form a package. Such a spinning unit includes a yarn defect detection device capable of detecting a defective portion generated during spinning. The spinning unit adjusts the yarn quality by cutting and removing the defect detected by the yarn defect detection device (for example, Patent Document 1). [0003] However, the conventional spinning unit is equipped with a yarn delivery device that delivers the spun yarn produced, and the yarn defect detection device is disposed between the yarn delivery device and the winding device (for example, Patent Document ...
