Description

DETAILED DESCRIPTION OF THE INVENTION As shown in FIG.
A false twisting device that falsely twists the yarn by nipping the yarn is known.

In such a false twisting device, a large number of pairs of belts 1 and 2, ie, false twisting weights, are arranged side by side on a horizontal frame and are commonly driven by a running belt in the horizontal frame. Conventional belt 1, 2
The driving pulley 3 and driven pulley 4 were fixed on one support tube, and the support tube was fixed to the horizontal frame, so when thread cutting etc.
It is not possible to stop the running of only a specific false twisting weight, making threading work extremely dangerous, and when replacing the belt, the running belt must be stopped and all the belts of all weights stopped running. The drawback was that it could not be done. The present invention fixes the support tubes that support the drive pulley 3 and the driven pulley 4 to the horizontal frame so that they can rotate independently.
- It is possible to stop the running of belts 1 and 2 by separating only a specific weight from the running belt.

The present invention will be explained in detail below with reference to FIGS. 2 to 4.

The support tube 5a of the belt 1 is rotatably supported by the housing 11a, the support tube 5b of the belt 2 is fixed to the housing 11b, and the housings 11a, 11b are rotatably supported by a pin 20 on a plywood 19, and the plywood 19 to the horizontal frames 16a, 16b, each support tube 5a
, 5b are independently rotatably supported by the horizontal frames 16a, 16b.

A shaft 6 is rotatably supported by the support tubes 5a and 5b via bearings, and the drive pulley 3 is fixed to one end of the shaft 6, and the drive pulley 18 is fixed to the other end.

A large number of support tubes 5a, 5b are installed at equal pitches in the longitudinal direction of the horizontal frames 16a, 16b, forming a large number of false-twisted bells. The driving pulleys 18 of the weights come into contact and the belts 1 and 2 of each weight are commonly driven. The driven pulley 4 is rotatably supported by a shaft 9 that stands on a sliding piece 8 that is fitted in the long grooves 7 of the support tubes 5a, 5b so as to be movable in a direction perpendicular to the shaft 6.

Reference numeral 10 denotes a tension spring for the belts 1 and 2 that urges the revolving piece 8 in a direction away from the shaft 6.

A lever 14 fixed to the pin 13 is engaged with a pin 15 protruding from the sliding piece 8, and the support tube 5a is rotated by the shaft 6.
Rotating force is applied around the center to press the belt toe onto the belt 2.

The plywood 19 is attached to the horizontal frame 16a by bolts 21 (Fig. 4).
16b. 22 is the housing 11a, 11b
23 is a hole for inserting the bolt 21 drilled in the plywood 19, and 23 is a hole for inserting the housing 11a, 11b drilled in the plywood 19.
, 16b has a screw hole 25 for the bolt 21 and a support tube 5a,
A long hole 24 for insertion of 5b is provided.

FIG. 4 shows a guide pulley for the running belt 17. 2
6 is a spring that urges the housings 11a, 11b to pivot in a direction away from the plywood 19; 28 is a magnet fixed on the plywood 19; 29 is a housing 11a, 11
This is an iron piece fixed to b.

・During the false twisting work, the iron piece 29 is attracted and held by the magnet 28 against the bias of the spring 26, and the housings 11a, 11b and the support tubes 5a, 5b are made of plywood as shown by the solid lines in FIGS. 2 and 3. Keep it fixed at 19.

If the iron piece 29 is pulled away from the magnet 28, the spring 26
As a result, the housings 11a and 11b turn around the pin 20 in the direction away from the plywood 19, and the contact portion 2 of the housing
7 (Fig. 2) hits a part of the plywood 19, the housing is fixed and the belt support device is in the state indicated by the chain line in Figs. Separation belts 1 and 2 can be stopped independently.

Furthermore, if the plywood 19 is attached to and detached from the machine frames 16a and 16b in this state, the pulley 18 and the belt 17 do not come into contact with each other, and the operation can be performed very easily.

Note that the longest hole 24 needs to have a length that allows the drive pulley 18a at the silver wire position to easily pass through. As described above, in the present invention, since the support tubes 5a and 6b are fixed to the horizontal frames 16a and 16b so as to be able to rotate independently, it is possible to stop the running of the belts 1 and 2 only at a predetermined weight. The belt can be easily replaced and the belt can be easily inserted into the horizontal frame.

In addition, since the housing that supports the support tube is usually fixed to the plywood using a magnet, the support tube and belt can be positioned without vibrating in the direction of rotation of the housing, allowing stable temporary work to be performed, and the rotation of the housing. Sometimes, it can be easily turned by simply separating it from the iron piece, and the workability is also good.
