Problems solved by technology

[0006] Depending on the deviation of the gate, there may be cases where the gate cannot be properly rotated by the first link
If the gate cannot be rotated properly in this way, there is a possibility that the jointing trolley stops abnormally.
In addition, if the gate cannot be properly rotated, there is a possibility that an unreasonable force is applied to the gate and / or the first connecting portion, which may cause deformation and / or damage.

Embodiment Construction

[0035] Next, a spinning frame (spinning machine, textile machine) according to an embodiment of the present invention will be described with reference to the drawings. figure 1 The illustrated spinning machine 1 includes a plurality of spinning units (winding units) 2 , piecing carts (working carts) 3 , power box 5 , blower box 80 , suction pipe 85 , and machine control device 90 which are arranged side by side.

[0036] The machine body control device 90 is a device that collectively manages the various components included in the spinning machine 1 , and includes a monitor 91 and input keys 92 . The operator can display the setting and status of a specific spinning unit 2 or all the spinning units 2 on the monitor 91 by performing appropriate operations using the input keys 92 .

[0037] The suction pipe 85 is provided below the spinning unit 2 in the machine height direction along the direction in which the spinning units 2 are juxtaposed. The suction pipe 85 is connected t...

Abstract

PROBLEM TO BE SOLVED: To provide a textile machine in which even when a shutter is displaced from a normal rotational position, the shutter can be appropriately rotated.SOLUTION: A main body portion 61 of a shutter 60 can be switched between a state of closing a supply hole 31 of a suction duct 85 and a state of opening the supply hole 31 by turning. An operated portion 62 is provided securely in the main body portion 61. An operating portion 24, when the shutter 60 is at a position displaced from the normal position by more than a predetermined rotation amount, contacts the operated portion 62 to rotate the shutter 60. A movable cylindrical portion 26 is provided separately and independently from the operated portion 24 and contacts the main body portion 61 of the shutter 60 disposed at the normal position to rotate the shutter 60. A bracket 29 holds the operating portion 24 at a position where the operating portion 24 does not contact the main body portion 61 and the operating portion 24 can contact the operated portion 62.

Description

technical field [0001] The present invention mainly relates to a structure for applying a negative pressure to the work cart in a textile machine equipped with the work cart. Background technique [0002] Textile machines such as spinning machines and automatic winders may employ a structure in which multiple yarn processing units are arranged in a row. Among such textile machines, there is known a work cart that travels to the position of a yarn processing unit to be processed and performs predetermined yarn processing on the unit. For example, Japanese Patent Application Laid-Open No. 2013-67900 discloses a piecing cart that travels to the position of a spinning unit to be processed and performs piecing work on the spinning unit. [0003] The piecing trolley described in JP 2013-67900 A is equipped with a first guide device and a second guide device in order to suck and catch the yarn during the yarn joining operation. This splicing cart includes a first connecting porti...
