Description

Detailed Description of the Invention Technical Field The present invention provides a method in which a large number of weft guide portions (Δ) having weft guide holes are arranged in parallel in the weft insertion direction, and a guide passage for the weft to be inserted by a fluid is formed in the weft guide hole. The IJ fluid jets (A=I-type looms) are related to the yarn inserting guide yam 1 in the I-type loom.

PRIOR ART Conventionally, as shown in FIGS. 1 to 4, for example, the inserting blade part of the inserting guide device has been used as a guide device. l Monoka has been adopted. The spinning guide section I L shown in Figures 1 and 2
L An elastic piece 1C is integrally formed with synthetic resin to prevent the phenomenon that the weft yarn jumps out from the guide hole 'la through the exit opening 11) during insertion of 1 m. Shitachi no guru. However, this elastic Li-I CLL
Due to the need for the weft to escape smoothly when reeding (411))
It is necessary to form the weft thread guide part + IV piece, but in the case of integrally forming means, the weft guide part +
41 is extremely difficult to form integrally.

The weft guide member 2 shown in FIG. 3 is composed of a kite body 2a made of synthetic resin and an elastic piece 2b made of metal.

The elastic piece 2b is formed separately and then attached to the kite main body 2a, but its attachment is troublesome and tends to result in variations in quality.

The weft guide member 3 shown in FIGS. 1(a) and (1+) is formed in a T-shape so that the peripheral wall of the weft guide hole 3a converges toward the side opposite to the weft insertion side. This tapered peripheral wall has the function of rectifying the fluid flow that causes the weft to fly.
This can stabilize the flight of the weft threads. Following,
It is desirable that the circumferential wall of the guide hole 3a be formed so as to have less air resistance.

However, with synthetic resin that is easy to load, the weft force is 11 parts 4A.
3, the air resistance on the peripheral wall of the guide hole 3a can be reduced, but contact friction between the warp threads and the synthetic resin guide member 3 can cause severe wear and damage to the guide member 3. , poor durability.

Therefore, if the weft guide member 3 is formed of a metal material such as nofluminium in consideration of this point, the processing of A is 5!
It has the disadvantage of being ugly.

Purpose The present invention has been made in consideration of the above-mentioned problems, and its purpose is to warp the parts of the weft thread guide member related to the warp threads and the weft threads in an appropriate shape, such as 4Δv'1, respectively. It is an object of the present invention to provide a cotton inserting guide device for a fluid injection type loom, which is capable of stabilizing weft inserting, improving durability, and improving ease of manufacture.

Structure In order to achieve the above-mentioned object, in the present invention, a yarn guide member is constituted by a forming body forming a weft guide hole and a pair of supports supporting the forming body, and as described above in the IC0 embodiment, An embodiment embodying the present invention will be described with reference to FIGS. 5 to 7.
The weft guide parts 6 arranged in parallel include a weft guide hole forming body 7 made of synthetic resin and a pair made of Luminous 11 that holds the forming body 7 from the reed side and front side, that is, from the front and rear of the Ilk machine. 1M mating protrusions 7i1 and 71+ are formed in the vertical direction at the rear and front ends of the guide hole forming body 7, respectively. The fitting protrusions 7a and 7b fit into the fitting holes 8a and 9a provided at the inner ends of both supports 8.9, which are provided in a shifted position J5. In this state, the base block 10 is folded onto the sleigh 4 (4) The base ends of both supports 8 and 9 are pressed by the screw 12 screwed into the front of the base block 10 in the f410a. Based on this, the length of the L1 lug 10 and the length of the L1 culm 1 are pressed and supported by a press-fitting body 11 that extends to the right. Guide hole forming body 7
One end is formed into a thin piece (hereinafter referred to as elastic piece 7C), and is spaced apart from the tip of the support 8 on the reed side, and the tip is spaced at an appropriate distance from the other end of the guide hole forming body 7. is forming. Therefore, the weft inserted by the weft fluid flies in the weft guide hole 7d formed by the guide hole forming body 7, and during this flight, the Depending on the presence of the weft or the same inner hole 7 d h + et al.
Between the tips of 9, jl''J straw 1j) 1 appearance n i 3 does not fly out and the current 9! is prevented J1.

This kind of (14-piece weft guide part) tAG smell (
If it is easy to manufacture the guide forming body 7, the bullet ↑'L
J''17G is the weft thread guide hole 7 (1 to 61 yarn 11 (required for 1 out) - 111 (with appropriate spacing from the tip of the side support 8). In the conventional forming means of integrally forming the same bullet 1 rehearsal 7C and both supports 8., this interval formation is effective. In case of I-C, since the guide hole forming body 7 and the support body ε3 are formed separately, the above-mentioned interval formation is extremely easy.Furthermore, when forming the elastic piece 7G which requires elastic force, Synthetic resins are much easier to process than metals, and are superior to metals even in terms of elasticity (JLj).

On the other hand, both supports 8.9 are made of metal,
This is due to the frequent contact between the weft guide member 6 and the warp threads T due to the reed movement of the slay 4.
This is effective in preventing wear and tear.

In the weft guide member 6 of this embodiment, the portion in contact with the warp T is formed by a metal support 8.9,
The peripheral wall of the weft guide hole 7d that guides the flight of the weft yarn is separately formed by a guide hole forming body 7 made of synthetic resin to improve the a3 wear resistance in the contact relationship with the C1 warp. In addition, it is possible to stabilize the weft insertion state of the weft yarns, and furthermore, it is possible to facilitate manufacturing.

In addition, this embodiment employs a four-part structure in which the guide hole forming body 7 is held between the pair of supports 8 and 9 from the front and back of the guide hole forming body 7, Assembling is extremely easy. In addition, since these three parts (Δ) are assembled by mechanical pressure clamping, it is possible to replace the guide hole forming body 7 depending on the type of yarn, for example. That is, when the weft is a silk thread, a guide hole forming body is used in which an appropriate interval is provided between the tip of the elastic piece 7C and the other end of the guide hole forming body 7, and when the weft is a thick thread, a guide hole forming body is used. It is possible to use a guide hole forming body with this spacing of O.

d5, the present invention is not limited to the embodiments described above, and the embodiments shown in FIGS. 8 to 11 are also possible.

In the weft guide part '19 in this embodiment, the weft guide hole forming body 14 is connected to a pair of supports 15 and 16 from both sides.
It is held between base blocks 10 and 1.
In 0a (b), both supports 1='j (4V15.16's proximal end is pressed and clamped by a pair of front and rear press members 17 and 18 by the pushing action of the screw 12. zu“
In other words, V-shaped locks 1♂117a, 18a formed in the vertical direction are formed in the inner surfaces of the Ryogawa joints 17 and 18 in multiple steps in the longitudinal direction of the Ryogawa joints 17 and 18. , the proximal joint edges of both supports 15 and 16 - the front and rear edges formed in a UV shape are press-fitted into the locks 1M17a and 18a, and J3 is pressed, and due to this press-fitting action. Both supporting holes 15 and 16 hold the guide hole forming body 14 in pressure contact with each other from both sides.

According to this embodiment, the same effects as in the previous embodiment can be obtained, and the interval between the weft guide members 19 can be changed as appropriate, so that appropriate warp handling can be performed according to the warp density. be. 1. Also, the weft guide member may be constructed using a weft guide hole forming body that does not have an elastic piece for preventing the weft from flying out, and in this case, the forming body may be made of metal.b TIJfi'r : It is. Alternatively, the supports 8, 9 and 15.16 may be molded from synthetic resin, but in this case it is preferable to use synthetic resin containing deflon, which has high sliding properties and high abrasion resistance.
