1 is a perspective view of a conventional weiss guide assembly.

FIG. 2 is a cross-sectional view of the weft guide assembly of FIG. 1 as a horizontal plane passing through the gastric gland. FIG.

3 is an enlarged front view of a conventional guide member.

4 and 5 are enlarged front views corresponding to FIG. 3 of the first and second guide members constituting the weft guide assembly of the present invention.

The present invention relates to a weft guide member for guiding the gas injecting body and the weft yarn is arranged in a large number in the inlet direction in the fluid spray loom.

In fluid injection looms, weft yarns are placed in a high-speed air stream injected from the main nozzle and placed in the upper grain path in the inclined opening, so that the weft non-splitting path formed by the array of weft guide members arranged in multiples is engraved. do.

In addition, the air nozzle of the main nozzle alone is not able to blow the weft over the direct width at a sufficient speed. Therefore, a means for coordinating the flow from the auxiliary nozzle with the main classification is provided by installing an appropriate number of auxiliary nozzles for the body frame. It can also be done.

For example, as shown in FIG. 1, the main body has a body divided into a generally straight portion 1a and an arc-shaped curved portion 1b, and the free end of the straight portion 1a and the free end of the curved portion 1b are wefted therebetween. A plurality of first guide members 1 approaching each other leaving the escape opening 1c is arranged in the indentation direction (arrow D) to fix the body frame 3 as indicated by the sign 4, and at the same time, the curved portion between these first guide members 1 The second guide member 2 having 2a but not having the same portion as the straight portion 1a of the first guide member 1 is properly installed, and the bent portion 2a and the auxiliary nozzle 5 of the second guide member 2 are in the indentation direction D Thus forming a nearly circular weft. The auxiliary nozzle 5 has an air jet port 5a as shown in FIG. 2, and the auxiliary air jet 5b is ejected from the air jet port 5a to assist the weft of the weft by the main jet (not shown).

Classification 5b meanders in the weft non-lane 6 and encounters a guide member on the flow path.

FIG. 3 is a front view showing the state when classification 5b from the auxiliary nozzle 5 hits the first guide member 1, and the first guide member 1 of FIG. 3 is slightly different in shape from that shown in FIG. Had the same function.

In the conventional weft guide assembly, when the auxiliary nozzle 5 has, for example, two air outlets 5a, the classification 5b from the upper injection port 5a is relatively upward of the inner circumferential surface 1d of the curved portion 1b, which forms the majority of the weft non-spinner 6. When the class 5b encounters the inner circumferential surface 1d, a part thereof tends to rebound upward and flow toward the weft escape opening 1c along the upper inner circumferential surface as shown by the inner circumferential surface 1d.

For this reason, in the fluid injection type loom using such an auxiliary nozzle, the fault which the weft injects from the weft escape opening 1c inadvertently under the influence of the above-mentioned repellent air flow toward the gastric escape opening 1c at the time of gastric entrance is recognized. Therefore, the object of the present invention is to provide a weft guide assembly that can prevent the weft from exiting the weft by sufficiently repelling until the repellent air reaches the weft escape opening even when the classification from the auxiliary nozzle is rebounded upward and downward from the inner circumference. Is in.

Referring to the accompanying drawings, one embodiment of the weed guide assembly according to the present invention is as follows.

4 and 5 are views corresponding to FIG. 3 showing the front faces of the first guide member 1 'and the second guide member 2' constituting the weft guide assembly according to the present invention, respectively. And the second guide member 2 'are installed on the body frame in the manner shown in FIG. 1 as in the first guide member 1 and the second guide member 2 described above, and the auxiliary nozzle 5 is the same.

Therefore, the figure which shows the state which assembled these agent members 1 ', 2', and 5 can be abbreviate | omitted.

In FIG. 4, the first guide member 1 'has a main body branched into a straight portion 1a' and a curved portion 1b ', and the free end of the straight portion 1a' and the free end of the curved portion 1b 'have a split weft on both sides. It is approaching mutually, leaving opening 1c '.

The inner circumferential surface of the curved portion 1b ', which forms the weft non-orbital 6, is generally perpendicular to the upper end of the upper surface 7 and the inclined surface slightly upward toward the gastric escape opening 1c' and the rounded portion 8a at the inner end of the abnormal surface 7 At the bottom of lateral 8 and bilateral 8, it consists of a lower surface 9 which slopes slightly downward in a row past the rounded part 8b, of which surfaces 7, 8 and 9 are generally I am ordered by type.

The upper surface 7 is in a curved relationship "<" in a relatively large angle with respect to the weft escape opening 1c '.

On the other hand, the face 10 of the weft non-majority of the straight part 1a 'is connected to the outer end of 9 when it passes through the round part 8c. Since the lower surface 9 is inclined downward toward the other end, the path to the inlet of the weft escape opening 1c 'extends through the rounded portion 8b, the lower surface 9, the rounded portion 8c and the inner surface 10.

On the other hand, the second guide member 2 'has a curved portion 2a' having a shape substantially coincident with the curved portion 1b 'of the first guide member 1', and has a straight portion 1a 'of the first guide member 1'. Since the auxiliary nozzle 5 is provided, the free end of the curved part 2a 'and the free end of the auxiliary nozzle 5 are mutually approaching, leaving the above-mentioned weft escape opening 1c' between them.

Since the curved portions of the first and second guide members have substantially the same shape, the curved portion 2a 'of the second guide member 2' also has the above-described surfaces 7, 8a, 8b and 9.

However, lower surface 9 extends the outer end to the vicinity of the auxiliary nozzle and downwards therefrom. (Section) 2b.

The curved portions of the first guide member 1 'and the second guide member 2' shown in FIGS. 4 and 5, respectively, are as described above. The weft guide assembly according to the present invention, although curved upward, may employ a first guide member and a second guide member having a curved portion that generally form a circular weft non-mains as shown in FIG. 1 or 3. good.

The auxiliary nozzle 5 provided on the open side of the curved portion 2a 'of the second guide member 2' has the air inlet 5a exiting there from the air inlet 5b, as is apparent in FIG. 4 and FIG. From the furthest part, ie in the embodiment shown, is oriented generally towards the rounded part 8b.

In order to direct the air injection port 5a, the auxiliary nozzle 5 of FIG. 4 is thickly formed, and the surface 5c of the nozzle tip side defining the air injection port 5a is inclined downward toward the rounded part 8b.

In addition, in the auxiliary nozzle 5 of FIG. 5 showing the modification, 5d is inserted to be inserted at the tip of the nozzle, and 5c is inclined downward toward the rounded part 8b farthest from the weft escape opening 1c 'as shown. have.

These inclined surfaces 5c are suitable for directing the classification 5b in a predetermined direction.

The first guide member and the second guide member shown in Figs. 4 and 5 are in the position at the time of indentation.

Therefore, as can be seen in these figures, the part of the weft non-majority furthest from the weft tool outlet opening 1c ', that is, the rounded part 8b, is located near the phase path 6 at the time of inlet, so that the classification from the auxiliary nozzle 5 is weft. Works effectively on

In the wesa guide assembly of the present invention having the auxiliary nozzle 5 configured as described above, the classification 5b which is ejected from the air injection port 5a of the auxiliary nozzle 5 is the weft non-trajectory located farthest from the weft escape path 1c ', and points to the part 8b of 6. Therefore, even if Class 5b is repelled by attaching to or near part 8b, the repellents 5b 'and 5b "pass a long path until the weft escape opening 1c' is reached. You don't have enough power to make it.

As shown in FIGS. 4 and 5, the curved portions of the first guide member and the second guide member are generally In the formation, the repulsion of the repellent streams 5b 'and 5b "is performed more effectively, so that the weft of the weft is more effectively prevented.

Therefore, according to the present invention, even if the classification from the auxiliary nozzles rebounds upward and downward from the inner circumference, the weft guide assembly which can prevent the weft from retreating until the repellent air reaches the weft escape opening is It can be provided.
