Description

[Detailed description of the invention] The present invention consists of a shuttle main body comprising a storage chamber for accommodating a coreless bundle of foil yarn, and a guide device for guiding the foil yarn released from the coreless bundle stored in the storage chamber. By providing this, it is possible to release the foil threads (weft threads) smoothly and neatly, and
Foil yarn can be used almost to the end, greatly improving the economic efficiency of foil yarn, and can also reduce the number of times a coreless bundle is refilled to the shuttlecock, contributing to improved weaving efficiency. Regarding shirts for use.

As shown in FIG. 5, the conventional foil yarn shirttle is constructed so that the foil yarn C, which is released from the coreless bundle housed in a storage chamber a, is pulled out to the outside through a yarn path d. A coreless bundle is usually formed in such a way that the foil yarn C is releasably wound into a cylindrical shape from the inside, and the foil yarn C is sequentially drawn outward from a pull-out hole e provided at the center of the surface. has been done.

In such a shirttle for foil yarn, when the foil yarn C is released, it is stretched between an arbitrary position on the inner surface of the coreless bundle and the pull-out hole e, and the foil yarn of the same length is pulled out. Considering this case, the tension of the stretched foil thread C becomes abnormally large in the area g near the extraction hole e compared to other areas,
Moreover, it will be abruptly lifted.

Therefore, the foil yarn C is often drawn out in a twisted state, and sometimes becomes twisted in a complicated manner into a lump or knot, which impairs the quality of the woven fabric.

In addition, when the yarn layer of the coreless bundle becomes thin, due to this phenomenon, the yarn layer part of the coreless bundle becomes distorted at the area g near the pull-out hole e, and the coreless bundle becomes thinner. It becomes unable to maintain its cylindrical shape and collapses, making it impossible to release the foil thread C thereafter.

As a result, a large amount of expensive foil yarn is wasted, which is completely uneconomical, and the number of times the coreless bundle is replenished increases accordingly, which causes a decrease in weaving efficiency.

The purpose of the present invention is to provide a shirttle for foil yarn that can solve these problems, and one embodiment thereof will be described below with reference to the drawings.

1 to 4, a shirt toll 1 for foil yarn according to the present invention comprises a shirt toll main body 2 and a guide tool 3. As shown in FIGS.

The shirttle main body 2 has a boat shape, and a storage chamber 7 for accommodating a coreless bundle 6 of the foil yarn 5 is recessed near one end of its upper surface. A yarn path 9 consisting of a concave groove extending linearly along the line is continuously provided.

In the thread path 9, a finger insertion hole 10 is recessed in front of the storage chamber 7, and in front of the finger insertion hole 10, a long groove 11 consisting of an elongated rectangular recess is recessed.

Further, a rectangular parallelepiped-shaped support stand 12 is installed in the long groove 11 so that it can be raised and lowered by pivoting one end of the support stand 12 to a position near the tip of the long groove 11 using a pin 13.

The coreless bundle 6 accommodated in the accommodation chamber 7 is made by winding the foil yarn 5 releasably from the inside into a cylindrical shape, and through the pull-out hole 15 provided through the yarn layer in the center of the surface of the coreless bundle 6. It is formed so that it can be pulled out sequentially toward the outside.

Note that 16 is a lid body that can close the storage chamber 7.

The guide tool 3 is a support rod 17 made of a relatively long straight steel wire.
An annular guide piece 19 is provided at the tip of the coreless booklet 6, through which the foil thread 5 to be released can pass through the pull-out hole 15 of the coreless booklet 6. A guide piece 19 is attached to the tip of the support rod 17 by winding a steel wire around a groove 19b provided around a circular ring 19a of ceramic or ceramic type.

The guide tool 3 is such that the base of the support rod 17 is embedded and fixed in the vicinity of the upper end of the end surface S so as to protrude from the other end end surface S of the support base 12 toward the accommodation chamber 7 side, It can be raised and lowered as the support stand 12 is raised and lowered.

Further, the guide tool 3 tilts the support base 12 and moves the long groove 11.
In the state in which the coreless bundle 6 is stored in the yarn path 9, the guide piece 19 is located at the center of the coreless bundle 6 housed in the storage chamber 7.

In addition, 20 in the figure is a knob for hooking the finger inserted into the finger insertion hole 10 when standing up the delivered support 12; The surface fasteners are attached to the lower surface and the bottom surface of the long groove 11, and the support base 12 can be fixed to the shirttle main body 2 by the surface adhesion of the double-sided fasteners 21 and 22.

Then, with the support stand 12 in an upright state, the foil thread 5 is inserted through the guide piece 19 at the tip of the guide tool 3, and the guide piece 19 is inserted into the pull-out hole 15.
While inserting it into the coreless end 6 through the support stand 12
When the cover body 16 is closed after tilting and storing it in the long groove 11, the guide piece 19 will be located at the center of the coreless bundle 6, as shown in FIGS. 3 and 4. At this time, due to surface adhesion between the hook and loop fastener 21 and the hook and loop fastener 22, the guide tool 3 is fixed to the shirt handle main body 2 in this state.

Therefore, while the foil yarn 5 is being pulled out, the foil yarn 5 released from the inside of the coreless bundle 6 is temporarily moved to the guide piece 19, that is, the coreless bundle 6
is pulled out toward the center, and then sequentially pulled out along the support rod 17.

In this way, the foil thread 5 to be released is always once wrapped in the coreless bundle 6.
, the tension of the foil threads 5 stretched between an arbitrary position on the inner surface of the coreless bundle 6 and the guide piece 19 is approximately constant, and the tension of the foil threads 5 is approximately constant. , it will be released quietly at a substantially uniform speed in any part of the inner surface.

Therefore, it is possible to avoid as much as possible the possibility that the foil threads 5 that are drawn out will be twisted, and the foil threads 5 can be straightened and released smoothly.

Furthermore, when the foil yarn 5 is released, no unreasonable force is applied to the coreless bundle 6, so even when the yarn layer of the coreless bundle 6 becomes thin,
The coreless bundle 6 can maintain its current cylindrical shape, making it possible to use up almost all of the foil yarn 5 to the end.

As mentioned above, the foil yarn shirttle of the present invention uses a guiding tool to gently release the foil yarn from the coreless bundle in order to pull it out to the approximate center of the coreless bundle. Therefore, the foil yarn (weft) can be released smoothly and neatly, improving the quality of the woven fabric, and the foil yarn can be used almost to the end, which improves the economic efficiency of the foil yarn. In addition to significantly improving the
It is possible to reduce the number of refills to the weaving machine and improve weaving efficiency and productivity.

In addition, in the foil yarn shirttle of the present invention, the guide tool 3 is as follows:
The guide piece 19 extends from the front position of the storage chamber 7 toward the storage chamber 7, and is fixed to the shuttlecock main body 2 so that the guide piece 19 formed at the tip thereof is located approximately at the center of the coreless bundle 6. Then, the shape, mounting position, and mounting means of the guide tool 3 can be arbitrarily selected.

In addition, the guide piece 19 can be of various shapes that can guide the foil yarn, such as a circular ring of the type described in the embodiment, and if a ring body is used, the thread can be inserted as appropriate. A small gap may be provided for this purpose.
