Detailed Description of the Invention

[0001]

[Industrial application] In the production of synthetic fibers, when winding a spun yarn, when the yarn is cut or a device malfunctions, the yarn is automatically cut and the suction port is used. A yarn breakage processing device is used that sucks and prevents the yarn from advancing in the subsequent process. The present invention relates to a yarn converging device used for collecting yarns and guiding them to a suction port in this yarn breakage processing device.

2. Description of the Related Art Conventionally, a yarn converging device 1 shown in FIG. 3 has been used. This device 1 is provided with a plurality of arms 2, 2 having a substantially V-shaped tip on both sides of a yarn Y, ... Then, the yarns, ... Are sandwiched and collected, and then moved backward and guided to the suction port 3.

This device 1 requires two arms 2, 2 and performs two operations of moving them to the center and rearward, so that the mechanism is complicated and the cost is high.

A yarn converging device 4 shown in FIG. 4 is also used. The device 4 is provided with an arm 5 having a substantially V-shaped tip on one side of the yarns Y, ... And moving the arm 5 to the other side to collect the yarns Y ,. It leads to.

In this device 4, although the mechanism is simple, since the yarns Y, ... Are largely bent and are not so close to the suction port 6, a large suction force is required and the reliability of the operation is unsatisfactory. There is.

[0006]

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to realize a yarn converging device which is simpler, lower in cost, and more reliable in operation.

[0007]

SUMMARY OF THE INVENTION The present invention is a straight line in the left-right direction.
In parallel with each other, having a vertical rotary shaft positioned behind the yarn that advances in the vertical direction and a groove having a V-shaped cut in the circumferential direction and attached to the rotary shaft. The yarn converging device is composed of a movable guide member that rotates and collects the yarns at one location and guides the yarns to the suction port.

Further, according to the present invention, in the above-mentioned apparatus, a fixed guide member is provided which surrounds the juxtaposed yarns and has a concave portion for guiding the yarns gathered by the movable guide member to the suction port so as to concentrate them on the suction port. The yarn converging device having the above is included.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The following will specifically describe one embodiment of the present invention with reference to the drawings showing a part of a yarn cutting device.

In this yarn converging device 10, the yarns Y,
Are parallel to each other in a straight line in the left-right direction and are vertically advanced from the upper side to the lower side. Behind this yarn Y, ...
A vertical rotary shaft 11 is provided, and the lower part of the rotary shaft 11 is connected to a rotary actuator 12. Two movable guide members 13, 13 are attached to the rotary shaft 11 at upper and lower two positions with a space therebetween. The movable guide member 13 has a groove 14 that is cut in the circumferential direction and has a substantially V-shaped inner portion, and is always positioned (represented by a solid line) substantially behind the yarns Y, ... When (indicated by phantom lines)
The yarns Y, ... Are gathered at one location on the inner side of the groove 14.

The suction port 15 is provided at the rear of the yarns Y, ... At an intermediate height position between the movable guide members 13, 13, and the tip end thereof is at a position where the gathered yarns Y ,. Is set.

Fixed guide members 16 and 16 are provided above and below the movable guide members 13 and 13, respectively.
The fixed guide members 16, 16 have a substantially rectangular peripheral edge, surround the perimeters of the yarns Y, ... Which are arranged side by side, and guide the gathered yarns Y ,. Have.

The cutting device 1 is provided below the suction port 15.
8 are provided. This cutting device 18 has a fixed blade 19
And the movable blade 20, and by rotating the movable blade 20 with the rotary actuator 21, the gathered yarns Y, ... Can be cut.

Since the yarn converging device 10 has the above-mentioned structure, it operates as follows.

When a yarn cutting or a device failure occurs in a winding machine or the like equipped with the device 10, a sensor detects it, and the yarn breakage processing device including the yarn converging device 10 operates. To do. That is, first, the rotary actuator 12 operates to move the movable guide members 13, 13
Rotates, the yarns Y, ... Are gathered and guided to the tip of the suction port 15. Immediately after this, the rotary actuator 21 operates, the movable blade 20 rotates, and the lower part of the suction port 15 of the gathered yarns Y, ... Is cut. The suction port 15 also operates simultaneously with the start of the operation of the yarn breaker, and suction is started from the front end. Therefore, the cut yarns Y, ... Go into the suction port 15 and do not proceed to the previous process.

Although two movable guide members are provided in the above embodiment, only one movable guide member may be provided depending on the usage conditions. Further, the fixed guide member may be provided in two pieces, or may be provided in only one piece or in no piece.

[0017]

As described above, since the yarn converging device of the present invention can collect the yarns and guide them to the suction port by simply rotating the movable guide member, the structure is extremely simple and low. It will be a cost. Also, you can guide the yarn until it hits the suction port without bending it greatly,
The operation is reliable.

Furthermore, if a fixed guide member is provided,
Even if some yarns become loose due to cutting, etc., they can be reliably inserted into the groove of the movable guide member and guided to the suction port.
The certainty of operation is further improved.
