AI Technical Summary

Problems solved by technology

However, the length of the fiber bundle attached to the spun yarn is not controlled
Therefore, depending on the length of the fiber bundle portion of the spun yarn end, it may not be possible to easily pull out the yarn end from the package wound by the winding device.

Embodiment Construction

[0027] Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. In addition, in this specification, "upstream" and "downstream" mean upstream and downstream in the yarn moving direction during spinning. In addition, in image 3 In , arrows indicated by dotted lines indicate signal lines.

[0028] figure 1 The illustrated spinning machine 1 includes a plurality of spinning units 2 arranged in parallel. This spinning machine 1 includes a piecing cart 3 , a blower box 80 , and a power box 5 . In the following description, the yarn passage side of the spun yarn 10 may be referred to as the near side of the spinning machine 1 with respect to the yarn joining cart 3, and the opposite side may be referred to as the rear side. An operator's passage extending along the direction in which the spinning units 2 are arranged is provided on the near side of the spinning machine 1 .

[0029] Such as figure 1 As shown, each spinning...

Abstract

A pneumatic spinning device includes a nozzle block (134) including a whirling airflow generating nozzle (127) adapted to inject spinning compressed air into a spinning chamber (126) to generate the whirling airflow in the spinning chamber (126), a flow pipe (200) adapted to enable flow of the spinning compressed air to be supplied to the whirling airflow generating nozzle (127), and a spinning switching valve (203) provided to the flow pipe (200) and adapted to permit or shut the flow of the spinning compressed air that flows through the flow pipe (200). A volume inside a first flow pipe (201) is set such that a length of a fiber bundle (10e) at a yarn end of the spun yarn (10) cut by the shut of the flow of the spinning compressed air is a first length.

Description

technical field [0001] The invention relates to an air spinning device, a spinning unit, a spinning machine and an air spinning method. Background technique [0002] Conventionally, a spinning unit described in JP 2006-144136 A is known as a technique in this field. The spinning device included in this spinning unit produces a spun yarn by injecting compressed air into a spinning chamber to generate a whirling airflow and twisting a fiber bundle introduced into the spinning chamber by the whirling airflow. The spun yarn spun by the spinning device is wound into a package by a winding device disposed downstream. A yarn clearer for detecting yarn defects of the spun yarn is arranged between the spinning device and the winding device. [0003] When the yarn defect is detected by the yarn clearer, the spinning device stops spraying compressed air into the spinning chamber to stop the twisting of the fiber bundle. The winding device winds the spun yarn in a state where the twi...
