DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The outline of an embodiment of the present invention will be described with reference to FIGS. Traverse thread guide 1
Are arranged on the traverse rod 10, and take-up units 19 are provided at positions corresponding to the respective yarn guides 1. The traverse rod 10 is supported by a support member 13 disposed at an appropriate position, is connected to a drive unit 14 provided at the machine end, and reciprocates. When the traverse rod 10 reciprocates, the plurality of yarn guides 1 traverse simultaneously. The winding unit 19 includes the package 12, the friction roller 11, and the cradle arm 18, and the friction roller 11 is driven by a driving source (not shown).
Package 12 supported on cradle arm 18
Is driven to rotate by the friction roller 11, and the yarn Y is wound up.

The drive unit 14 is, for example, a cam box. Inside the drum, there is a grooved drum (not shown). By rotating the drum, a follower member (not shown) connected to the traverse rod 10 moves along the groove. The traverse rod 10 is restricted in vertical movement by the support member 13 described above.
The follower member includes the traverse rod 10 and the support member 1.
Reciprocate along 3.

The yarn guide 1 will be described with reference to FIGS. The yarn guide 1 is composed of a support part 2 which is a resin molded product and a ceramic yarn guide part 3. The yarn guide part 3 is embedded in the support part 2 and
It is integrally molded with. The support part 2 includes an arm 20 and a joint part 15. The arm 20 is a substantially Y-shaped member viewed from the side, and the center of the v-shaped member is a plate-like member for reinforcement.
, And a thread guide portion 3 is provided at the end. or,
The joint portion 15 is a U-shaped member having a width greater than that of the arm 20 and a part of a ring shape being cut, and has an inner diameter substantially equal to the diameter of the traverse rod 10 which is a circular pipe. The arm 20 is not limited to a Y-shaped member whose center is reinforced. The arm 20 may be any member as long as the yarn guide portion 3 is at an appropriate position with respect to the winding unit 19 and can withstand a traverse load. The shape does not matter.

The yarn guide 3 will be described with reference to FIGS. The yarn guide section 3 includes a yarn guide section 7 that guides the yarn Y, a base section 8 that supports the yarn guide section 7 at the distal end, and a flat section 21 that is supported at the tail end of the base section 8.
A step 7 is formed at a portion where the base 8 integrally formed of ceramic supports the flat portion 21. Then, a part of the base portion 8 and the step portion (first detachment resistance portion) 7 and the flat portion 2
1 is embedded in the arm 20 as the embedded portion 9 and is integrally formed with the support portion 2. The thread guide 7 is a convex member having a thickness of about 1 mm, and has an open upper end and a circular thread guide hole. The base 8 is a member slightly smaller in width than the arm 20, and the flat portion 21 is also a member having the same width as the base 8. The flat portion 21 is provided with a hole 6, and at the time of integral molding, the inside of the hole (second detachment resistance portion) 6 is filled with resin.

In the yarn guide 1 of the present embodiment, the shape of the yarn guide portion 3 is reduced to a function of only the yarn guide to reduce the size and weight, and to reduce the bonding area due to the reduction in size. The decrease in strength is compensated for by forming the yarn guide 3 integrally with the support 2. In addition, the step 7 provided in the embedding portion 9 becomes a resistance after the integral molding, and the resin flows into the hole 6 and solidifies. Therefore, the thread guide portion 3 is supported by the strong thread tension generated at the time of high-speed traverse. There is no separation from 2.

Further, in the present embodiment, from the viewpoint of bonding the yarn guide 1 to the traverse rod 10 made of carbon fiber, the material of the support 2 is made of ABS resin containing polyamide resin. I have.

The ABS resin was selected because it is lightweight and easy to mold, has good adhesion to carbon fibers, and can be used with a cyano-based instant adhesive, but the ABS resin alone has poor durability. I found that there was a problem. According to the durability test, the support portion 2 deteriorated in about one month, and a problem that the support portion 2 was broken near the yarn guide portion 3 occurred. For this reason, in order to improve the durability of the support part 2, it is decided to include a polyamide resin which does not have good adhesion to carbon fiber by itself but is excellent in wear resistance and durability.
As a result, the adhesiveness does not change much with the ABS resin alone,
It has become possible to produce a yarn guide 1 having excellent durability.

Finally, a method of attaching the traverse thread guide 1 of the present embodiment to the traverse rod 10 will be described below with reference to FIG. The traverse rod 10 is moved to the predetermined position by moving the drive unit 14 described above, and then the yarn guide 1 is set on the traverse rod 10 in accordance with the predetermined position, for example, so that the yarn guide 1 comes to the end of the package 12. I do. When, for example, a cyano-based instantaneous adhesive is dropped and injected into the end 16 from the adhesive dropping positions A and B vertically above the traverse rod 10,
The yarn guide 1 is instantaneously adhered to the traverse rod 10.

It is preferable that the gap between the traverse rod 10 and the joint surface 4 is as small as possible because the adhesive can be securely fixed with the adhesive, and the joint surface 4 has the same shape and the substantially same diameter as the traverse rod 10. Then, in a state where the yarn guide 1 having the yarn Y passed through the yarn guide portion 3 is set on the traverse rod 10, molding is performed so that both ends of the end portion 16 are located vertically above the center of the traverse rod 10. Then, the thread guide 1 can be temporarily fixed to the traverse rod 10, and the adhesive can be easily poured into the end 16 while visually confirming the position of the end 16, thereby improving workability. It is more preferable to perform

The effects that can be expected from the above embodiment will be described below. (1) In the yarn guide 1 of the present embodiment, the material of the support portion 2 that holds substantially the entirety of the yarn guide 1 is made of resin, and the yarn guide portion 3 is reduced in size and weight, and is integrally molded. Approximately 1/9 the weight of the thread guide without compromising the mounting strength of
A significant reduction in weight was achieved, contributing to a higher winding speed. Further, by devising the shape of the portion embedded in the support portion 2 of the yarn guide portion 3, the yarn guide portion 3 after integral molding does not come off.

(2) Not only does the winding speed increase with the weight reduction of the yarn guide 1, but also the collision noise generated when the traverse rod 10 is inverted is reduced. this is,
Since the inertial force generated when the traverse rod 10 is inverted is reduced as the weight including the traverse rod 10 and the yarn guide 1 is reduced, the inertial force is also reduced. 1
The deflection between the support members 13 of zero is also reduced. Due to this decrease, the gap between the traverse rod 10 and the support member 13 is also reduced, so that the strong collision between the traverse rod 10 and the support member 13 is also reduced, and the collision noise generated by the collision is also reduced.

The present invention may be embodied as follows. Since the drive unit 14 for reciprocating the traverse rod 10 is not directly related to the yarn guide 1 of the present invention,
Although the cam box is provided with a grooved drum, the invention is not limited to the grooved drum, and the traverse rod 10 may be reciprocated using a heart-shaped cam, and the traverse rod 10 may be reciprocated by another mechanism. Is also good.

[0022]

Since the present invention is configured as described above, it has the following effects.

According to the first aspect of the present invention, the weight of the thread guide is reduced by forming the support portion from resin,
The traverse speed can be increased, and the winding speed can be increased. Further, since the small-sized thread guide is integrally formed with the support, the attachment strength of the thread guide can be ensured even if the area for attaching the thread guide is small, so that the weight of the thread guide can be reduced.

According to the second aspect of the invention, the yarn guide is provided.
When attaching to the traverse rod, the thread guide
In addition, temporary fixing is possible, and bonding can be easily performed. Further
Does not come off after bonding .

According to the third aspect of the present invention, since the ABS resin is used, the adhesiveness to the traverse rod is good.
Furthermore, by making the ABS resin contain a polyamide resin,
The adhesiveness with the ABS resin does not change so much, and deterioration such as cracking is unlikely to occur, so that the durability of the yarn guide is improved.
