Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a tuft processing apparatus for a fragment loom.

[Conventional technology]

JP-A-63-28950 discloses that a false twist device and a cutter are installed on the same bracket. When the false twist device and the cutter are mounted on the same bracket, the mechanical elements for the treatment of the tufts are unitized, so that the mounting, maintenance and inspection are facilitated.

[Problems of the prior art]

However, according to the above technique, the false twisting device and the cutter are separately mounted at different positions on the bracket, and the rotation transmission mechanisms from the main shaft of the driving source are also separately provided, so that the rotation transmission path is complicated. When either the cutter or the false twisting device is moved, it is necessary to move both rotation transmission mechanisms, and the workability at the time of adjustment is poor.

[Object of the invention]

Accordingly, it is an object of the present invention to integrate the false twisting device and the cutter, and to eliminate the disadvantages of the prior art with another configuration.

[Solution of the Invention]

To this end, the present invention is configured such that the rotary blade of the discarding ear cutter is directly attached to the rotary shaft of the false twisting device, and the rotary blade is disposed between the end of the woven fabric and the waste thread. Furthermore, a rotating shaft is constituted by a hollow rotor shaft of a motor for driving a false twisting device, a guide path for a waste thread can be formed inside the rotating shaft, and a cup-shaped holder attached to a stator side of the motor. The fixed blade may be attached to the portion of the yarn guide slit.

[Function of the invention]

The above-mentioned tassel treatment device is attached between the end of the woven fabric and the waste thread.

During weaving, the discarded yarn intersects with the tufts of the woven fabric, enters the inside of the yarn guide path of the rotating shaft, and is twisted while sandwiching the tufts by the rotating motion of the rotating shaft. On the other hand, the rotating blade of the discarded ear cutter is driven by the rotating shaft, and cuts the tuft between the end of the woven fabric and the discarded thread to separate it from the woven fabric.

As described above, since the rotation axis of the false twist device also serves as the rotation axis of the rotary discarding ear cutter, the structure is simple, the size can be reduced, and the relative positional relationship between them becomes constant. The false twisting operation of the waste thread is stabilized, and the cutting operation of the tuft is also ensured. In addition, their position adjustment can be performed while maintaining the relative positional relationship between the two.

〔Example〕

FIG. 1 and FIG. 2 show the configuration of the chamber ear processing device 1 of the present invention.

This in-the-ear processing device 1 is assembled by a false twist device 2 and a rotary shearing type disposable ear cutter 3.

The false twisting device 2 is attached to the one end of the woven fabric 5 near the tuft 6 on the traveling path of the throwing yarn 7, and is rotated by the rotation of the rotating shaft 4 so that the false twisting yarn 7 intersects with the tuft 6. Give twists. The rotating shaft 4 of this embodiment is directly driven by a dedicated motor 8. The motor 8 is assembled by a rotor 9 and a stator 10.
The rotating shaft 4 is constituted by a hollow rotor shaft, forms a yarn guide path 11 therein, and has a plurality of, e.g., Three thread guide holes 12 are formed.

Further, the rotary shearing type disposable ear cutter 3 includes a rotary blade 13 and a fixed blade 14. The fixed blade 14 is formed by a slit for guiding the tufts formed on the peripheral surface of the cup-shaped holder 15.
Attach to one edge inside 16 and hold
It is attached to the stator 10 of the motor 8 together with 15. The bracket 19 is also attached to the stator 10 by the set screw 27. In this mounted state, the rotating shaft 4 is
It faces inside from 15 central holes 17. In addition, rotary blade 13
Is configured as one or two or more, for example, four windmills that are in sliding contact with the fixed blade 14, and is attached to the rotary shaft 4 inside the holder 15 by a central boss 18 in a non-rotating state.

The plurality of discarded yarns 7 are guided by a yarn guide 20 attached to a bracket 19, pass through a yarn guide portion 11 inside the rotary shaft 4, pass through a yarn guide hole 12, and are wound around a guide roller 21. The direction is changed, and it can be drawn into a predetermined position and discharged. Here, the thread guide 20 is attached to the long hole 22 of the bracket 19 in a state where the position can be adjusted by an adjusting bolt / nut 23.

The tuft processing apparatus 1 is installed on a frame of a loom or the like so as to obtain a desired tuft length according to the weaving width. Thereafter, the position of the yarn guide 20 is adjusted so that the distance between the end of the woven fabric 5 and the waste yarn 7 is set to an appropriate distance at the pre-weaving position.

During weaving, the inserted weft yarn 24 intersects with the warp yarn 25 and at the same time intersects with several discarded yarns 7 at the end, and
Driven before weaving. On the other hand, the motor 8 rotates the rotary shaft 4 to twist the discarded yarn 7 at the yarn guide hole 12 at the rear end. In this way,
The waste thread 7 sandwiches and holds the end of the weft thread 24, that is, the portion of the tuft 6 of the woven fabric 5.

As the weaving progresses, the woven fabric 5 and the waste thread 7 move in the winding direction, so that the tuft 6 at the end of the woven fabric 5 is held inside the guide slit 16 while being held by the waste thread 7. Get in. At this time, the rotary blade 13 is driven by the rotary shaft 4 to apply a shearing force to the fixed blade 14 to cut the tuft 6 from the end of the woven fabric 5 at a predetermined length. As a result, the tuft 6 cut off from the end of the woven fabric 5 enters the inside of the yarn guide path 11 inside the rotary shaft 4 while being held by the waste thread 7, and is surely twisted by the waste thread 7. , Is guided by the guide roller 21 through the yarn guide hole 12, and is guided to a predetermined discharge position.

[Other embodiments]

In the above embodiment, the rotary discarding ear cutter 3 is composed of a rotary blade 13 and a fixed blade 14 for shearing operation. However, as shown in FIG. 3, the rotary discarding ear cutter 3 may be constituted only by a cup-shaped rotating blade 13, for example, and may be formed in a shape having an annular blade at an open end thereof. .

In this case, the rotary blade 13 cuts sequentially against the traveling direction of the tuft 6 held by the woven fabric 5 and the waste thread 7.

In the above embodiment, the rotary shaft 4 is directly driven by the dedicated motor 8. However, the rotation axis 4
May be configured to utilize the rotational force of the main shaft of the loom and guide it to the rotational shaft via a winding transmission means or the like.

〔The invention's effect〕

 According to the present invention, the following specific effects can be obtained.

Since the rotating shaft of the false twist device also serves as the rotating shaft of the rotary discarding ear cutter, the structure is simple, the whole device is small, and the handling thereof is easy.

In addition, the false twist device and the rotary discarding ear cutter are integrated by the rotating shaft, and their relative positional relationship is always constant. It can be performed while holding the position, and the position adjustment work can be simplified.

Furthermore, since the rotating shaft of the false twist device is driven by a dedicated motor, and the hollow rotor shaft is configured as a rotating shaft, the body of the false twist device is replaced with a motor,
The drive system for the rotating shaft can be simplified.
