Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a crack removing device for a hank machine that can remove cracks using a simple and rational mechanism.

[Prior art and its problems]

Usually, a skein ring for dyeing yarn is made as follows. First, a skein yarn bundle is made by winding many skeins in a circular shape using a hank machine, and then this skein yarn bundle is removed from cracks using a crack thread from a separately provided crack removal device. Filter.

By the way, various types of such crack removing devices have been known in the past.For example, Japanese Patent Publication No. 1983-3825 discloses a plurality of crack removing devices in which each bundle is loosely wound so as to divide the crack thread into a plurality of bundles. Discloses a device for forming individual filament loops, and also
Japanese Patent No. 55-34749 discloses a device for passing a starting end of a fluffy yarn into a loop of fluffy yarn scooped up into a ring through a skein yarn and tying it to a terminal end.

However, all conventional crack removal devices have complicated mechanisms and tend to be large in size, and are disadvantageous in terms of cost, failure, etc., and have problems in that they are difficult to maintain. However, the reality is that no suitable crack removing device has been proposed for the so-called S-shaped crack removing method, which involves winding the cracked thread in an ∞ shape, which is the object of the device of the present invention.

[Means for solving problems]

In order to solve the various problems of the prior art, the present invention has a simple mechanism, especially the S-shaped gap removal method.
Furthermore, the object is to provide a novel crack removing device that can be operated in a fully automatic manner, and this is achieved by the device shown below.

That is, the gap removing device 1 of the hank machine according to the present invention moves forward and backward, and has a needle portion 3 that enters the skein yarn bundle P and divides it into two when moving forward, and a needle portion 3 that protrudes to one side of the rear portion of the needle portion 3 and rotates the shaft. By selectively locking each bundle P ₁ (P ₂ ) that has been inverted approximately 180 degrees at the center and pushing it apart, a pipe insertion space S is created between it and the other bundle P ₂ (P ₁ ).
It is provided with a pushing arrow 2 consisting of a pushing piece part 4 that forms a. In addition, a suction pipe 5 is disposed on one side of the skein bundle P, and a yarn blowing pipe 6 is disposed on the other side for passing the cracked yarn H to the suction pipe 5 through the insertion space S.
is arranged so that crack removal can be performed by controlling the pusher arrow 2 and the respective pipes 5 and 6.

[Effect]

Next, the operation of the present invention will be explained.

In the gap removing device 1 according to the present invention, when the pushing arrow 2 moves forward, the needle portion 3 pierces the skein bundle P and divides it into two bundles _P1 and _P2 . Furthermore, since the pushing piece 4 locks on one bundle _P1 and pushes it apart,
A pipe insertion space S is formed between the other bundle _P2 . Therefore, the yarn blowing pipe 6 can pass the open yarn H to the suction pipe 5 through the space S.

On the other hand, while returning the thread blowing pipe 6, push piece part 4
If the pushing arrow 2 is moved backward until the locking of the bundle P ₁ is released, and the pusher 2 is advanced after reversing the pusher piece 4, the pusher piece 4 will be attached to the other bundle _P2 . Since the pipe is locked and pushed apart, a pipe insertion space S is formed in which the opening surface side is opposite to the initial one. Therefore, the yarn blowing pipe 6 can pass the gap yarn H to the suction pipe 5 through the space S, and as a result, S-shaped gap removal can be performed.

〔Example〕

Hereinafter, preferred embodiments of the present invention will be described in detail based on the drawings. Fig. 1 is a front view showing the main parts of the crack removal device according to the present invention, Fig. 2 is a perspective view of the vicinity of the tip of the suction pipe in the same device, and Figs. 3 A to F are crack removal performed by the same device. It is a front view showing a process one by one.

First, the structure of this device 1 will be explained. 1st
In the figure, 20 is a skein frame, and by winding the skeins of this skein frame 20, a skein bundle P having, for example, a hexagonal shape in side view is created. The present device 1 is placed above the skein bundle P.

In the device 1, reference numeral 11 denotes a base, which is vertically raised and lowered by an air cylinder (not shown) or the like. A pusher arrow 2 extends vertically downward from the bottom of the base 11. The push arrow 2 is rotatably supported on the base 11 and can be rotated 180 degrees by an air cylinder or the like. The pushing arrow 2 consists of a vertical needle part 3 and a pushing piece part 4 integrally attached to the upper part of the needle part 3.
The needle portion 3 has a pointed lower end and is located approximately at the center of the skein bundle P in the width direction. Further, the pusher piece 4 is formed of a plate material, is fixed along the axis of the needle part 3, and protrudes to one side. The pusher piece 4 has a bottom side 4d substantially horizontal,
Its length is selected to be at least larger than the divided width of the skein bundle P. Note that the needle portion 3 extends a predetermined length downward from the base 4d. Also,
By rotating the pushing arrow 2 by 180 degrees, the pushing piece 4 is reversed to a position substantially parallel to the width direction of the skein bundle P.

On the other hand, a suction pipe 5 is disposed on one side of the skein bundle P, and this suction pipe 5 has a fixed positional relationship with respect to the base 11. The suction pipe 5 is vertical and bent inward at the bottom. Further, as shown in FIG. 2, a cut groove 12 of a predetermined length is provided along the axial direction from the upper end of the suction port 13 at the lower end for easily and reliably cutting the wide yarn. This suction pipe 5 sucks air from the suction port 13 by supplying negative pressure.

Furthermore, on the other side of the skein bundle P, there is a thread blowing pipe 6.
Allocate. This pipe 6 has a semicircular shape as a whole,
The upper end is supported by one side of the L-shaped lever member 14.
The other end of the lever member 14 is rotatably supported by the base 11, and the intermediate portion of the lever member 14 is rotatably coupled to the link 15. Therefore, by displacing the link 15 using, for example, the air cylinder 16, it is possible to displace the air outlet 17 at the lower end of the thread blowing pipe 6 to the suction port 13 of the suction pipe 5 in a manner across the skein bundle P. can. Further, the yarn blowing pipe 6 has a supply hole 18 for supplying a wide yarn in the middle thereof. Note that the blowing pipe 6 has a blowing outlet 17 from its upper end.
Pressure air blows through.

In FIG. 1, reference numeral 19 denotes an L-shaped skein lifting hook provided as needed, as will be described later.The upper end of the hook is rotatably supported and can be displaced in a direction perpendicular to the winding direction of the skein bundle P. Can be done.

Next, with reference to FIG. 3, a case in which S-shaped cracks are removed using the slot removing device will be explained step by step.

Figure A shows the state immediately before crack removal.
In this state, when the base 11 is lowered, the needle part 3 sticks into the skein bundle P as shown in _FIG . Press down. A pipe insertion space S is thereby formed. Then, by moving the yarn blowing pipe 6 through the space S and bringing the blowing outlet 17 into contact with the suction port 13 of the suction pipe 5, the starting end of the wide yarn H is sucked into the suction port 13.

Next, as shown in _FIG . Flip (rotate 180 degrees). At this time, make sure that the needle part 3 does not come off from the skein bundle P.

Then, when the pushing arrow ₂ is lowered as shown in FIG. . Next, by displacing the thread blowing pipe 6 through the space S and bringing the blowing outlet 17 into contact with the suction port 13 of the suction pipe 5, the open yarn H coming out of the thread blowing pipe 6 is sucked into the suction port 13. On this occasion,
The open yarn H wound around the bundle P ₁ enters the cut groove 12 of the suction pipe 5 depending on its positional relationship, so if the cutter is positioned at point K as shown in FIG. When returning the pipe 6, the wide yarn coming out of the blowing pipe 6 can be surely identified and cut. In addition, in the same figure D, if the bundle P ₁ obstructs the movement of the thread blowing pipe 6, the hook ₁₉ shown in FIG.

Then, as shown in FIG.
Just return it to the initial position. Note that both the terminal end and the starting end of the wide yarn H are in a state where they are sucked into the suction pipe 5. Thereafter, when the starting and ending ends of the cracked thread are tied together using a knotter (not shown), the crack removal is completed.

Although the embodiments have been described in detail above, the present invention is not limited to these embodiments.
The shape of the pushing piece part, the needle part, and each pipe in the pushing arrow can be arbitrarily implemented. Other details such as configuration, shape, arrangement, quantity, etc. may be arbitrarily changed without departing from the spirit of the present invention.

〔Effect of the invention〕

As described above, the crack removing device of the hank machine according to the present invention implements the S-shaped crack removing method by using the pushing arrow consisting of the needle part and the pusher part, and therefore has the following effects. .

Full automation of the S-shaped hole removal method can be achieved. Therefore, it is possible to significantly improve the efficiency of the method, which conventionally required manual work.

In particular, since it is constructed using a push arrow that can be used for both left and right hands by reversing it, the mechanism can be simplified and the entire device can be made smaller and more compact. In addition, by simplifying the configuration, it is possible to reduce costs, facilitate maintenance, and reduce failures.
