Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a foil thread separation and delivery device.

Foil thread a with patterns and pictures used for special textiles
As shown in Figure 3, there is paper on both ends (the part indicated by the dotted line)
After the foil yarn parallel piece A is finely cut leaving a . .

A large number of foil threads a, which are closely arranged in parallel on such a thread holding table C, are woven by pinching the ends of the foil threads one by one between the thumb and forefinger and pulling them out one by one as shown in Figure 4. ,
It is very tedious and difficult manual work to pick a large number of closely paralleled foil threads a one by one from the thread holding table C according to their order, so it is often necessary to pick two or three threads at the same time or to pick them in order. There was an important problem in weaving that the pieces were picked in the opposite direction, resulting in incorrect weaving of the order. In order to solve this problem, a "foil thread separating device" (Showa 5th Patent No. 109087) filed by the present patent applicant has already been proposed.

Such a device is based on the assumption that the foil threads A are lined up in the order in which the parallel foil thread pieces A have the selvedge paper b attached, and the parallel box thread pieces A with the selvedge paper b still attached are It is supported by being sandwiched between the belts on the upper running side of the feeding means, which are double endless belts, and is fed at a very slow speed by the rotation of the inorganic belt. A cutting device consisting of circular rotary blades arranged above and below is used to cut the foil yarn a one by one according to its order at the edge of the edge paper b of the foil yarn parallel piece A, and then cut the foil yarn one by one in order. arranged at a position through which the foil thread portion near the edge paper portion of the parallel piece A passes, and whose peripheral speed is greater than the feeding speed of the foil thread parallel piece A by the feeding means;
This is a device in which the cut-off foil threads a are sequentially held by a holding roller feeding device, and the distance between the foil threads is widened, and the foil threads are sent out. With such a device, the foil yarn a of the foil yarn parallel piece A to be cut and separated is made of paper or plastic film, and its length is extremely large compared to its thickness and width. They tend to bend or twist in the length direction due to temperature, humidity) and handling.

Therefore, when trying to cut and separate the foil threads using such a device, if the foil threads a are deformed such as bending or twisting, when the foil thread parallel pieces A are fed into the cut ends of the upper and lower circular rotary blades, the foil threads a may be cut apart from the cut ends. A situation occurs in which the foil yarn parallel piece A hits the peripheral part of the circular rotary blade and is not fed into the cut.
As the foil yarn a is fed, a breakage accident occurs in which it overlaps with the succeeding foil yarn a and breaks together, and when cutting, the edge paper b
Since the foil yarn a that is cut off from the foil can freely exhibit its bending and twisting, the cutting machine part of the foil yarn a bounces up and down or left and right at the same time as it is cut, so that it can hold the foil yarn after being cut. Accidents such as the roller feeding device not being able to pinch the foil threads, or the foil yarns being turned upside down, or two foil yarns being pinched at the same time, may occur. For this reason, there were cases in which it was not possible to separate the foil threads one by one from the foil thread parallel pieces in order and to widen the spacing between the foil threads and send them out. Therefore, even if the foil yarn to be cut and separated has deformation such as bending or twisting, the foil yarn can be separated one by one from the parallel pieces of foil yarn, and the foil yarn can be easily picked up during the weaving process. It is an object of the present invention to provide a foil thread separating and sending device which can send out foil threads with a greatly increased interval between them.

Next, this invention will be explained based on one embodiment shown in the drawings. There is a feeding means in which a plurality of double-width endless bands 11 and 12 run side by side at appropriate intervals, and the feeding means runs between the overlapping bands on the upper running side of the double endless bands 11 and 12. , parallel pieces of foil thread 9 with edge paper 10 attached to one side,
The parallel pieces are supported by being sandwiched so that the longitudinal direction of the foil yarn is perpendicular to the running direction of the endless bands 11 and 12, and fed in the lateral direction at a constant speed by the running of the endless bands 11 and 12. This is what I did.

On the side from which the parallel pieces of foil yarn 9 are sent by this feeding means, a rotating driving ball 3 and a rotating driven shaft 4 are arranged in the upper and lower directions counterclockwise from a direction perpendicular to the feeding direction of the parallel pieces of foil yarn when viewed from above the device. The circular rotary blades 1 and 2 are oriented and installed in a direction slightly shifted from the direction of the rotary drive shaft 3 and the rotary driven ball 4, respectively, at positions where the edges of the edge paper portions of the foil thread parallel pieces pass. The cylindrical edges of the circular rotary blades 1 and 2 are partially overlapped in the axial direction.

In addition, the position where the foil thread part near the edge paper part of the parallel piece of foil passes through the rotary drive shaft 3 and the rotary dependent key 4 has an outer diameter larger than the outer diameter of the circular rotary blades 1 and 2. Circular brush-like rotors 5 and 6 are provided, respectively. Furthermore, the rotation drive shaft 3
Feeding nipping rollers 7 and 8 are provided at positions opposite to the circular rotary blades 1 and 2 via the brush-like rotors 5 and 6 on the rotary driven shaft 4 and the rotary driven shaft 4, respectively.

The rotation of the rotary drive shaft 3 is controlled so that the peripheral speed of the feeding rollers 7 and 8 is greater than the feeding speed of the parallel pieces of foil yarn by the feeding means. One or both of the aforementioned holding rollers 7 and 8 for feeding are made of an elastic material, and both loafs 7 and 8 are pressed together to form a pressure-bonded holding portion between the rollers. Further, two sets of nipping rollers 7.8 are provided at appropriate intervals. Reference numeral 13 indicates a light emitting device installed outside the nipping rollers 7 and 8, and 4 indicates a light receiving element installed opposite to the light emitting device 13. When the cut foil thread is sent out between the two and reaches the light emitting device 13, , the light between the light-receiving element 14 is blocked, and as a result, a photoelectric switch mechanism operates to block the signal and stop the entire device. When the foil thread blocking the light between 13 and the light receiving element 14 is removed, the photoelectric switch mechanism is activated, and the mechanism that stops the entire device based on the signal is released, and the entire device is activated again.

According to such a device, when the endless bands 11 and 12 run to send parallel pieces of foil yarn 9 with one edge paper attached in a direction perpendicular to the length direction of the foil yarn, Before the upper and lower circular rotary blades 1 and 2 cut the parallel pieces of foil yarn 9, the bristles of the brush-like rotors 5 and 6 rub against both the front and back sides of the portion of the foil yarn 9 near the edge paper 10'. At the same time, he became fond of the foil thread 9.

As a result, the parallel pieces are fed without being pinched at the edge of the edge paper 10, that is, the part without deformation such as bending or twisting. The cutting is carried out accurately and smoothly, and the upper and lower circular rotary blades 1 and 2 cut the foil threads 9 one by one in order at the edges of the parallel pieces of selvedge paper 10. Even when the upper and lower circular rotary blades 1 and 2 cut the foil thread 9 and the foil thread 9 is separated from the selvedge paper 10 and becomes free, the hair-like portions of the brush-like rotors 5 and 6 are cut as they are. Since the key thread 9 is held in between,
The cut ends of the foil threads are prevented from floating (jumping up and down or left and right) and are transferred one by one in order. The foil threads 9' separated from the parallel pieces are held by the brush-shaped rotors 5, 6 as they are, and are moved to the feed-out nipping roller 7 as the brush-shaped rotors 5, 6 rotate. , 8 is fed into the crimping and holding parts.

Since the holding rollers 7 and 8 for feeding are oriented in a direction slightly counterclockwise from the direction perpendicular to the feeding direction of the foil yarn parallel pieces when viewed from above the device, the cut end of the cut foil yarn 9' is The parts are Takumochi loaf 7, 8 to Ogitoki roller 7, 8
The foil threads 9 are sent out in a long protruding state in the direction crossing the direction of , and since the peripheral speed of the supported rollers 7 and 8 is higher than the feeding speed of the foil thread parallel pieces, the foil threads 9 that are sent out sequentially are The intervals are widened and spread out in a fan shape.

The foil thread 9' cut in this way is passed to the holding roller 7,
8, and is fed out while being held between the holding rollers 7 and 8.
When the cutting side part that protrudes long in the direction intersecting the direction of the holding rollers 7 and 8 enters between the light emitter 13 and the light receiving element 14, a photoelectric switch mechanism is activated and the entire device is stopped by the signal. is activated and the entire device stops operating.

When weaving, when the foil thread existing between the light emitter 13 and the light receiving element 14 is pulled out, the photoelectric switch mechanism is activated, and the mechanism that stops the entire device is released by the signal, and the entire device operates in the same manner as described above. be. As described above, according to the foil yarn separating and sending device of the present invention, even if the foil yarn to be cut and separated has deformation such as bending or twisting, the foil yarn is separated from the parallel pieces of foil yarn one by one in order. Then, the cut side portion of the foil yarn becomes a long protruding fan shape and is fed out with the mutual interval widened.

As described above, the foil yarn separating and feeding device of the present invention makes it extremely easy to pick up a single thread of foil yarn during weaving work of foil yarn for special textiles, even when the foil yarn has deformations such as bends and twists. At the same time, it has the effect of being able to accurately pick according to the order.
