Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a yarn length adjusting device that can easily, easily, and accurately adjust the length of a yarn to shorten it in a short period of time. In particular, the present invention relates to a thread length adjustment device that can shorten the thread length of heddle threads used in pattern looms while the threads are suspended.

[Prior Art] Conventionally, 3,000 to 15,000 heddle threads (threading threads, batto threads) used in pattern looms are suspended to allow the warp threads to rise and fall to form pattern weaving. In addition, adjacent threads are tied to horse thread so that they are at a constant height to form a heddle. At the initial stage, the heights of these nodules are aligned at the same height, but over time, the nodules may elongate due to changes in temperature and humidity, or due to tension. Because the heddle threads relax and stretch, the height of the knotted part of the heddle thread is 1.
Each thread is different, with the knots of each thread forming large undulating heights. With such long and short patterned heddles, it becomes difficult to achieve accurate patterned weaving.

In such a case, it was usual to redo the knotting work of the heddle thread and horse thread.

In addition, threads (threads, strings, ropes, rubber cords, etc.) have traditionally been used in common structures and devices to suspend objects and components, or to tension them and maintain their positions. Although it is very commonly used as a component, even in such cases, the length of the thread is often elongated and the original purpose is no longer achieved, as in the case of the heddle thread of the pattern loom mentioned above. Even in such cases, it was usual to adjust the length of the thread to a shorter length by re-tying the knot.

[Problem to be solved by the invention] However, such re-tying work is time-consuming and labor-intensive, and in particular, re-tying work of re-tying thousands of heddle threads with horse threads is a waste of a great deal of labor and time. It was something that required

It is also possible to simply shorten the elongated heddle thread by providing a knot, but even if such a knot is provided, the formed knot will catch on the adjacent heddle thread and the pattern weaving command will not be transmitted accurately. The problem with such knots is that over time, the knots tend to come loose due to tension and become elongated again.

In view of the shortcomings of the prior art, an object of the present invention is to provide a thread length adjustment device that can easily, easily, and accurately adjust the length of a thread to shorten it in a short period of time. The object of the present invention is to provide a thread length adjustment device that can shorten the thread length while maintaining the thread in its used state.

In particular, the present invention enables the length of the heddle thread used in a pattern loom to be shortened simply, easily, in a short period of time, and with high accuracy while the heddle thread is suspended from the pattern loom. It is an object of the present invention to provide a thread length adjusting device that does not stretch and has excellent durability.

[Means for Solving the Problems] That is, the present invention has the following configuration in order to achieve the above object.

That is, the yarn length adjusting device of the present invention includes a pin for winding the yarn to adjust the yarn length to a shorter length, and a cylindrical covering member having a vertically openable and closable split for covering the pin and the yarn. It is characterized by the following.

(Function) The present invention provides a thread length adjustment device that can shorten the thread length while the thread is in use. In particular, it is a device that can adjust the length of the heddle thread used in a pattern loom while it is suspended from the pattern loom.

Note that the principle of the thread length adjusting device of the present invention can be applied to any linear or elongated thread regardless of its thickness or structure. In other words, the principle of the yarn length adjusting device of the present invention can be applied to strings (including rubber cords), ropes, tapes, etc. in addition to yarns to shorten their lengths.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The yarn length adjusting device of the present invention will be described below with reference to the drawings, using an example in which the yarn length adjusting device of the present invention is used for heddle yarns.

FIG. 1 is a side sectional view showing an example in which the thread length adjusting device of the present invention is used for heddle threads.

In this example, after the heddle thread 1 is wound around the pin 2 several times, the pin 2 is twisted one to several times, and the heddle thread 1 is twisted through the pin 2 to form the locking part 4. , the heddle thread 1, the locking part 4 and the pin 2 are enclosed in the tubular covering member 5 at the same time by opening the split 6 portion of the tubular covering member 5. This cylindrical covering member 5 preferably has an outer shape with tapers 7 at both ends, thereby preventing it from being caught by the adjacent heddle threads 1. Furthermore, the outer surface of the cylindrical covering member 5 has a low coefficient of friction.
For example, it is preferable to use a material coated or composited with silicone resin, fluorine resin, or the like. The cylindrical covering member 5 only needs to have a shape and condition that firmly grips the pin 2, and preferably has an internal structure in which the pin 2 and the locking portion 4 do not fall out from the cylindrical covering member 5. . For example, both ends of the cylindrical covering member 5 are connected to the heddle thread 1.
It can be said that a structure that is narrow enough to pass only through is a preferable structure.

The above-mentioned cylindrical covering member 5 has a split 6 in the longitudinal direction, and the heddle thread 1 and the pin 2 are opened by opening the split 6.
and the entire locking part 4 is wrapped around and gripped at once. Therefore, it is preferable that the cylindrical covering member 5 is made of a flexible material. In particular, a resin having rubber elasticity is preferable because it has high elasticity.

As such resin, resins commonly used for molded bodies can be used, such as polyamide resins, polyolefin resins, vinyl chloride resins,
Polyester resins, synthetic rubber, polyurethane resins, and mixed resins thereof can be used.

This cylindrical covering member 5 has a structure having an internal cavity as shown in FIG. 2, for example, in which the pin 2 and the locking portion 4 can be accommodated. Figure 2C shows a tube-shaped one made of rubber elastic material.
It may be made of such a flexible material.
However, in the case of such flexible rubber, it is preferable to take measures to reduce the friction with the adjacent heddle threads 1 on the surface.

The outer surfaces of both ends of the cylindrical covering member 5 are as shown in FIG. 2A.
And B, which preferably has a taper 7, does not have problems such as catching with the adjacent heddle threads 1. The angle of the taper 7 is not particularly limited and may be any angle as long as the adjacent heddle threads 1 are not caught.

The length of the heddle thread 1 is adjusted by winding the pin 2, and the length of the heddle thread 1 is adjusted mainly by the amount of winding. Therefore, it is convenient to use the thinner pins 2 for fine adjustment, and the thicker the pins 2, the more convenient to use them for larger adjustments.

In general, it is easy to use pins 2 that are 1/2 to 1/1 the thickness of the thread to be adjusted (the same applies to strings and ropes). In the case of heddle thread 1, pins 2 having a thickness of about 0.5 to 5 mm can be preferably used. Also, pin 2
The length of the cylindrical covering member 5 may be determined according to the length of the cylindrical covering member 5 to be used; in short, it must be shorter than the cylindrical covering member 5 and have a length that does not interfere with the thread length adjustment work. That's fine.

The shape of the pin 2 used in the present invention may be straight, but there are mechanisms 8 for locking the heddle thread 1 at both ends.
It is preferable that the

As the heddle thread locking mechanism 8 of the pin 2, for example, one having a shape as shown in FIG. 3 can be used. Type A has an end shaped like a key, nail head, ring, spiral, wave, etc. Pin 2 has one of the shapes of A throughout the pin 2. It is.

The method of locking the heddle thread 1 with the locking mechanism 8 is as shown in FIG. It is only necessary to introduce the heddle thread 1 into the locking mechanism 8, and the thread can be fastened very simply and easily.
This method has the advantage that the yarn length can be adjusted extremely quickly. It is also possible to lock the yarn using a combination of such a locking method and a method of twisting and locking the yarn.

It is also preferable to provide the above-described shape of the pin 2 at the center of the pin 2, since this makes it difficult to unwind the wound portion.

The material of the pin 2 may be general synthetic resin, metal, ceramic, glass, or natural plants (wood, wood, etc.).
It may be made of any material (such as bamboo), but it is easier to use metal because it is strong and durable.

The twist locking method shown in FIG. 1 is simple, but there is a risk that it will come undone if the cylindrical covering member 5 comes off. This method is very safe because even if the cylindrical covering member 5 comes off, it is securely locked by the locking mechanism.

To adjust the thread length, as shown in Figure 1, after winding the desired length of heddle thread 1 around pin 2, in the case of a straight pin, leave pin 1 twisted. After covering the cylindrical covering member 5 or, in the case of the pin 2 having the locking mechanism 8 shown in FIG. This is achieved by covering with a through-cylindrical covering member 5. In this method, after winding the thread 1, twisting it and locking it once,
If the pin 2 is passed through the locking mechanism 8, it may be possible to lock the pin 2 more firmly.

(Effects of the invention) The present invention allows the length of the thread to be shortened simply, easily, in a short time, and with high accuracy.
According to the present invention, it is possible to adjust the yarn to be adjusted while maintaining it in a used state.

In particular, the present invention is extremely useful for adjusting the thread length of heddle threads used in pattern looms to a shorter length. In other words, the thread length can be adjusted short while the heddle thread is suspended on the pattern loom, and
It can be adjusted accurately in a short period of time, does not re-stretch, is highly durable, does not catch adjacent heddle threads, and can accurately transmit pattern weaving commands.
