DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and an apparatus for treating a yarn end treated yarn in a loom for treating the weft yarn after weft insertion by the yarn end treated yarn.

[0002]

2. Description of the Related Art Japanese Patent Publication No. 51-9061 discloses that a yarn end-treated yarn from each loom is conveyed by suction to one collecting place in a state of being connected to the loom. And transferring it to a collection box. In this technique, since the yarn end treated yarn from each loom is suctioned and conveyed in a state of being connected to the loom, the following problems occur. (1) At the merging point of the suction pipes, the yarn end treatment yarns from the respective looms are entangled, and yarn jams occur. (2) Since the yarn end treated yarn is entangled in the pipe, if the yarn end treated yarn pulling device of one of the looms breaks down, the yarn end treated yarn of the other loom will not be conveyed, and suction conveyance will not be possible. It is easy to be certain.

[0003]

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to solve the above-mentioned drawbacks of the prior art by making the yarn end-treated yarn a length that can be easily processed and discharging the yarn to a predetermined position by a suction airflow. It is.

[0004]

To achieve the above object, the present invention connects one end of a suction pipe to a common suction source, branches the other end of the suction pipe, and connects the other end to a suction port on each loom side. Guiding, after cutting the yarn end treated yarn attracted by the traction device provided in each loom between the traction device and the suction port, the yarn end treated yarn is put on the suction airflow from the suction port and discharged. I have.

[0005]

Embodiment 1 FIGS. 1 and 2 show a yarn end treated yarn discharging device 1 according to Embodiment 1. FIG. The yarn end treatment yarn discharging device 1 includes a suction source 3 common to a plurality of looms 2 and a cage 2 with a filter.
2, a suction pipe 4 that branches and is guided for each loom 2, a pulling device 6 that guides a yarn end treatment thread 5 provided in each loom 2, and a suction port of the pulling device 6 and the suction pipe 4. 7, and is assembled by a cutter 8 that cuts the yarn end treatment yarn 5.

[0006] The yarn end treatment yarn 5 holds the end of the inserted weft yarn, but is then cut off from the end of the woven fabric,
Discarded with the end of the weft thread. The traction device 6 is provided for each loom 2 to guide the yarn end processing yarn 5 by the guide roller 9 and, for example, a pair of winding rollers 10. Container 1
1 inside. The container 11 is provided with the suction port 7 on the floor surface.
And has a bottom plate 12 that can be opened and closed,
For example, a photoelectric type thread amount sensor 13 and a corresponding reflecting mirror 14 are provided as needed at a position at a predetermined height on the upper inner surface.

The openable and closable bottom plate 12 is assembled by a lever 15 supported by a fulcrum 16 on a frame of the loom 2 and the like, and an air cylinder 17 for driving the lever 15. The cutter 8 is attached to a frame or the like of the loom 2 between the traction device 6 and the container 11, and is driven by a solenoid 18 or the like. These movable parts are operated by the control device 19.

During weaving of the loom 2, the pulling device 6 pulls the yarn end treatment yarn 5 and guides it into the container 11. When a predetermined amount of the yarn end treatment yarn 5 has accumulated inside the container 11,
The yarn amount sensor 13 generates an operation command signal,
Send to 9. Therefore, the control device 19 first operates the cutter 8 to move the yarn end treated yarn 5 to the pulling device 6 and the suction port 7.
Then, the bottom portion of the container 11 is opened by driving the air cylinder 17 and retreating the bottom plate 12. At this time, the cut yarn end treated yarn 5 falls from the inside of the container 11 to the inside of the suction port 7 and is sucked in the direction of the suction source 3 by the suction airflow inside the suction pipe 4,
It is accommodated in a car with filter 22 immediately before the suction source 3. The predetermined amount of the yarn end treatment yarn 5 is set to a value that does not cause clogging inside the suction pipe 4.

[0009]

[Embodiment 2] The embodiment shown in FIG.
1 is installed, the bottom plate 12 is rotatably supported by a support shaft 20, and the bottom plate 12 is opened and closed by a cylinder 21. When a predetermined amount of the yarn end treatment yarn 5 has accumulated inside the container 11,
The yarn amount sensor 13 detects the state, operates the cutter 8, cuts the yarn end processing yarn 5, and then opens the bottom plate 12 by the cylinder 21. Thus, similarly to the above-described embodiment, the yarn end treated yarn 5 inside the container 11 is separated from the drawn yarn end treated yarn 5 and rides on the suction airflow of the suction pipe 4 so as to pass through the suction port 7. Is discharged.

[0010]

[Embodiment 3] FIG. 4 shows that an ejector nozzle 23 is provided between the traction device 6 and the suction port 7, and the cutter 8 is operated for each predetermined pick of each loom 2 so that the yarn end treatment yarn 5 is ejected. This is an example in which the liquid is guided to the suction port 7 while being twisted by the nozzle 23 and discharged. The ejector nozzle 23 takes in compressed air 25 from the outside into the suction pipe 24 and twists the inside yarn end treatment yarn 5 by vortex.

The cutter 8 faces the inside of the suction pipe 24. And the controller 26 of the cutter 8
The cutting operation of the cutter 8 is controlled by inputting a predetermined number of pick signals. The predetermined number of picks is set such that the hanging end yarn 5 does not become entangled with the yarn end processing yarn 5 from another loom inside the suction pipe 4. .

[0012]

[Other Embodiments] The discharge point of the yarn end treated yarn 5 is determined by the container 11
In addition to the above, when the yarn end treatment yarn 5 is fully accumulated in the container 11, the yarn end treatment yarn 5 may be set for a fixed time or every predetermined pick as in the third embodiment. Irrespective of the presence or absence of the container 11, the loom 2 may be set to operate irregularly so that the discharge points do not overlap each other. These settings are set inside the control device 19 or the controller 26.

[0013]

According to the present invention, since the yarn end-treated yarn is sucked and discharged in a state of being cut into a predetermined length by the suction airflow inside the suction tube, the yarn is entangled inside the suction tube. No large ball is formed, and the yarn end treated yarn can be reliably and automatically collected.
