DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for preventing snare, which easily occurs in twisted yarns, particularly strong twisted yarns, and causes trouble during winding, aging, weaving and the like.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG.
For example, when the cheese C mounted in the lateral direction is wound around a cylindrical peg 32 of a reel 31 as a warp by a warper and fed as a weft of a high-speed automatic automatic loom, a cloth is applied to the cheese C. 33, a weight 34 is hung on the cloth to apply a required tension to the drawn yarn Y to prevent snare.

[0003] However, when replenishing cheese, it is necessary to carefully cover each piece of cheese with a cloth, which takes considerable time and effort, and the outer diameter of the cheese gradually decreases, so that the contact area between the cheese and the cloth changes. As a result, there is a problem that the snare S is easily generated when the warping machine or the loom suddenly stops.

As shown in FIG. 9, a tension device 36 provided with a disk-shaped washer 35 is widely used. However, when the running speed of the twisted yarn increases, the washer dances, so that a uniform tension is applied to the passing twisted yarn. It is difficult to install the device near the tip of the cheese C, and the position must be changed according to the size of the cheese.

[0005]

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a stirrup that can be installed in contact with a rewind end of a cheese or a cone (hereinafter simply referred to as cheese) and that constantly applies a uniform tension to a running twisted yarn. By completely preventing the snare,
It is still another object of the present invention to provide a twisted yarn snalling prevention device that can easily attach and detach cheese to be supplied and can quickly cope with cheeses of various sizes.

[0006]

In order to solve the above-mentioned problems, according to the present invention, a number of loops made of elastic filaments are arranged adjacent to the inner periphery of a ring member made of a ring-shaped cardboard and double-sided adhesive paper. Loops to overlap the loops
Thus, the ring-shaped cardboard was sandwiched between the double-sided adhesive paper and the double-sided adhesive paper, and these loops formed an annular ring which was pressed against the unwinding end of the twisted yarn unwound from the cheese.

The ring member is provided with a large number of round holes.
Preferably, keep the disengageable wear plate.

[0008]

[0009]

The running twisted yarn is constantly in contact with the elastic loop while rotating, so that a uniform required tension is always applied, and even if the running is suddenly stopped, the twisted yarn does not sag and snare is hardly generated.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS.

FIG. 1 and FIG. 2 show an example of an apparatus for preventing snare of a twisted yarn according to the present invention. As shown in the figure, the anti-snal device comprises an L-shaped support 2 having a base 3 attached to a creel 1 which stands substantially vertically, and an approximately true circle attached to a tip of the support 2. A ring member 4 having a circumference is provided. On the inner periphery of the ring member 4, a large number of loops 5 made of an elastic synthetic resin monofilament that comes into contact with the running twisted yarn Y are arranged.

A creel 1 is provided on a base 3 of the support 2.
The core 6 mounted on the peg 14 and supporting the wound tube B of the cheese C is slidably mounted. The core 6 has a regular polygonal shape which can be pressed into the bobbin tube B as described later.

The ring member 4 has an inner diameter larger than the outer diameter of the cheese C when the ring is full, and the through hole 8a of the ring support piece 8 is inserted into the support 2 and slid along the support 2. It can be fixed at an appropriate position on the support 2 by a set screw 10, and is detachable so that it can be easily replaced with another ring member having a different size. Instead of the set screw 10, a leaf spring is mounted in the through hole 8a, and is pressed against the support 2 to provide resistance to the slide of the support 2 so that the slide can be stopped at an arbitrary position and held at that position. Is also good.

The loop 5 is, for example, 500 m / min
In order not to damage the twisted yarn running at a high speed of about
A thick and smooth elastic nylon monofilament such as approximately 600 denier is used, and as shown in FIGS. 2 and 3, one of small holes 9 provided at equal pitches around the ring member 4. A plurality of parabolic loops 5 are fixed to the jumping small holes 9 with stoppers 11, and a number of parabolic loops 5 overlap with the adjacent loops 5. It is formed so that its inner diameter is slightly smaller than the outer diameter of the bobbin tube B. Therefore, the twisted yarn released from the cheese C comes into contact with the loop 5 to the end. The loop 5 can be made of a material such as its thickness and elasticity in accordance with the use, and can obtain required elasticity.

As shown in FIG. 3, the loop 5 is formed by turning the adjacent loop 5
2 overlap and the next loop 53
Are overlapped, and a part of each loop is sequentially formed so as to overlap the preceding loop such that the adjacent loop 54 overlaps the loop 53.

For this reason, when the twisted yarn Y released clockwise from the cheese C is engaged with the loop 51 at the contact point P, for example, the running force lifts the loop 51 to some extent. , Loop 53 and loop 5
4 are sequentially lifted, the restoring elastic force of the plurality of loops acts on the twisted yarn Y, and as the twisted yarn is released clockwise, the contact points P sequentially move clockwise, and the tension required for the twisted yarn, for example, a thin twisted yarn In this case, a tension of about 1 g to 3 g can be continuously and uniformly applied.

As described above, the loop 5 is formed so that each succeeding loop sequentially overlaps the preceding loop clockwise as viewed from the front front, and conversely, the twisted yarn is wound counterclockwise from the cheese C. The loops can be formed so that the loops sequentially overlap with each other in a counterclockwise direction in response to the release.

It is preferable that the ring member 4 is installed at substantially the same position as the end corner of the yarn layer of the cheese C or at a position as close as possible. This is for minimizing the distance between the contact point of the twisted yarn with the loop 5 and the point at which the twisted yarn separates from the cheese yarn layer, and to prevent the occurrence of snare during this time.

The ring member 4 slides on the support 2 in accordance with the size of the cheese, the type of twisted yarn, the rotational speed of a winding machine, a warper, a loom, or the like, that is, the running speed of the twisted yarn. The degree of contact can be appropriately adjusted.

Further, as the ring member 4 itself, a plurality of members having different sizes are prepared in accordance with the application, and the ring member 4 can be appropriately selected from them. Also, the loop 5 is formed by sequentially stacking a large number of monofilaments and fastening to the ring member as described above, and an appropriate shape such as continuously forming a similar loop from one monofilament can be appropriately selected. In addition, an elastic filament such as another synthetic resin material can be selected in addition to the nylon filament.

Next, as shown in FIG.
As shown in FIG. 4, a regular polygonal columnar core 6 for mounting a wound tube is attached via a bottom plate 13. The bobbin tube B is detachably supported by being pressed into the core 6. As described above, since the core 6 has a regular polygonal shape, the inscribed portion with the bobbin tube B is linear, the frictional resistance at the time of attachment and detachment is small, and the bobbin tube B has some deformation. Can also be easily press-fitted.

The core 6 is provided with a through hole 15 at the center, and is inserted into the peg 14 of the creel 1 and set screw 16
Fixed by The bottom plate 13 is provided with a long hole 17 for fixing the core, and the base 3 is also provided with the long hole 7. Therefore, the core 6 can be replaced according to the size of the cheese, and the mounting position can be changed as appropriate.

The core 6 has a shape other than a regular square,
The shape can be appropriately selected according to the application, such as a regular pentagon, a regular hexagon, or the like, and can also be formed into a pyramid-shaped regular polygonal cross section corresponding to a conical wound tube.

FIGS. 5, 6 and 7 show another embodiment according to the present invention. As shown, the ring member 19 is
It is formed of a ring-shaped thick paper 20 and a double-sided adhesive paper 22 having the same shape as the thick paper 20 provided with the release paper 21, and the loop 23 is sandwiched between the thick paper 20 and the double-sided adhesive paper 22.

The ring member 19 is peeled off from the release paper 21 and adhered to the round hole 25 formed in the flat support plate 24. The support plate 24 is formed in a size corresponding to the size of the creel, and is used by being attached to a bracket 26 of the creel.

The round holes 25 of the support plate 24 have substantially the same diameter as the inner diameter of the ring member 19, and are provided in large numbers at positions corresponding to the many cheeses to be mounted on the creel.

The ring member 19 can be easily detached from the support plate 24 as needed, and can be replaced.

In this embodiment, when a large number of cheeses are released and used at one time, for example, when attached to a creel such as a warping machine or a carpet loom, only one support plate is used, so that the advantage is very high efficiency. There is.

The apparatus for preventing snalling of a twisted yarn according to the present invention comprises a combination of a human silk thread such as acetate (trademark) and a polyester filament such as tetron (trademark).
It is particularly effective when used for so-called crepe cloths at regular time weaving of a so-called crepe cloth using a strong twisted yarn twisted to at least 00 t / m and having a hygroscopic property, a soft texture, a fine unevenness on the cloth surface and a beautiful luster. Can be completely prevented, and high productivity and high quality can be obtained.

The above-described apparatus for preventing snalling of twisted yarns is used for knitting machines, knitting machines, carpet looms, lace knitting machines, etc., such as knitting yarn machines, cheese winding machines, warping machines, high-speed automatic looms, etc. which handle strong twisted yarns. It is useful to attach it.

[0033]

According to the present invention, as described above, since a large number of elastic loops are annularly arranged on the inner periphery of the ring member, a uniform tension is always applied to the twisted yarn running in contact with the loop. And can be installed in contact with the cheese, so that even when the running of the twisted yarn is stopped, no snare or entanglement occurs. Further, a tension device using a washer which has been conventionally used can be omitted.

Further, the ring member is detachable from the support, so that it is possible to quickly cope with cheeses of various sizes.

Another advantage is that the operation of attaching and detaching the cheese to and from the peg can be performed quickly and reliably.
