Problems solved by technology

However, when the cutter is provided separately, the cost increases accordingly
In addition, when the yarn is cut by a cutter as in Patent Document 1 when a defective splicing is detected, the yarn is sometimes irregularly disordered due to violent release of tension applied to the yarn or twisting of the yarn. verb: move
As a result, it becomes difficult to catch the yarn end, and the efficiency of the piecing operation decreases.

Embodiment Construction

[0036] Next, a spinning frame according to an embodiment of the present invention will be described with reference to the drawings. In addition, in the following description, "upstream" and "downstream" mean upstream and downstream in the traveling direction of the fiber bundle and the spun yarn at the time of yarn winding.

[0037] A fine spinning machine (spinning machine, yarn winding machine) includes a plurality of spinning units (yarn winding units) 2 arranged side by side, and a body control device (not shown) that collectively manages the plurality of spinning units 2 . Such as figure 1 As shown, each spinning unit 2 winds the yarn (spun yarn 10) supplied from the yarn supply unit 5 by the winding device 26 to form a package 50.

[0038] The spinning machine is equipped with a control unit ( Figure 4 symbol 80). The control unit 80 is configured as a computer equipped with hardware such as Central Processing Unit (CPU; central processing unit), Read Only Memory (R...

Abstract

A spinning unit (2) of a spinning machine includes a yarn supplying section (5), a winding device (26), a yarn joining device (23), and a joint monitoring device (25). The yarn supplying section (5) is adapted to supply a spun yarn (10). The winding device (26) is adapted to wind the spun yarn (10) into a package (50). The yarn joining device (23) has a cutter (100). The joint monitoring device (25) monitors the spun yarn (10). The spinning machine (the spinning unit 2) cuts the continuous spun yarn (10) by the cutter (100) of the yarn joining device (23) in accordance with a monitoring result of the joint monitoring device (25).

Description

technical field [0001] The present invention mainly relates to a yarn winding machine provided with a piecing device. Background technique [0002] Conventionally, there is known a yarn winding machine that winds a yarn around a bobbin to form a package. Such a yarn winding machine generally includes a yarn monitoring device for detecting yarn defects and a piecing device for piecing. Such a yarn winding machine is disclosed in JP 2013-067892 A (Patent Document 1). [0003] The yarn winding mechanism of Patent Document 1 comprises: a yarn supplying unit; a winding device for winding the yarn into a package; a package rotation speed detection unit for detecting the rotation speed of the package; The yarn is spliced ​​to form a splice; the splice monitoring device monitors the splice; and the judging unit judges whether the splice is normal. The judging section judges whether or not the yarn splicing formed by the piecing device is normal based on the running speed of the y...
