In this fluid spray weaving machine, in which the weaving of the weft yarn is made by the fluid injected through the injection nozzle, such as a water jet weaving machine or the air jet weaving machine, this invention sprays the weft yarn remaining longer than necessary from the nozzle after the filling is completed. This invention relates to a weft reverse drawing device for a fluid spray loom which allows only the required length to remain at the distal end of the injection nozzle to be drawn back toward the nozzle to achieve a more ideal weaving.

In general, the intrusion in the apparatus in which the infiltration of the weft yarn such as a water jet loom or an air jet loom is made by the fluid injected through the injection nozzle generally proceeds as follows.

That is, when the wish is completed by the force of the fluid (water, air) sprayed from the spray nozzle, the body is fully charged and transfers the weft thread just before (weft and weft interlocking part). At the same time, the light and weft yarns interweave and the fabric is woven, the body is moved forward by the advancing of the body, and the woven weft yarns are cut by a cutter for the next uptake.

At this time, the weft cut by the cutter is a long obstacle from the end of the injection nozzle when viewed from the position of the injection nozzle and the cutter is a major obstacle to the supply of the next weft.

In particular, when there are two injection nozzles, the normal weft cannot be supplied due to the entanglement between the cut wefts.

Therefore, in the related art, a device which prevents entanglement and prevents entanglement has been used.

That is, as shown in FIG. 6, the weft station outlet 104 is installed between the weft wave strip 100 and the injection nozzle 102, and a curved space 106 is also formed on the inner surface of the reverse outlet 104, and the space The upper part 106 is formed by forming an air injection pipe 108, the front of the space portion 106 is to install a hooking network 112 through which a plurality of exhaust holes 110 are opened.

Therefore, when the weft yarn 114 is cut by the cutter after the inlet is completed between the inclined openings through the injection nozzle 102, the end of the cut weft yarn protrudes from the injection nozzle 102 and does not remain. 108, the weft yarn 114, which protrudes to the distal end portion of the injection nozzle 102, into the space portion 106, because it is sucked into the space portion 106 of the weft area outlet 104 by the blowing force of the air separated from the air. It is to be drawn back toward the injection nozzle 102 by the length of the suction weft, so that only the weft 114 of the appropriate length is left at the distal end of the injection nozzle 102 so that the ideal inlet proceeds.

However, the draw station drawer of this configuration was to cause the following problems.

That is, the weft 114 is formed by the injection force of the air injected from the air injection pipe 108 configured at the upper end of the reverse outlet 104 to allow the cut weft to be sucked into the space 106 of the weft zone outlet 104. It is to be sucked into the space portion 106 of the back-out outlet 104.

Therefore, since the injection amount of the air injected from the air injection pipe 108 is larger than the exhaust amount exhausted through the catching network 112, the air in the space 106 causes the vortex phenomenon, so that the weft yarns are entangled with each other. do.

In addition, because the back drawing length to the weft is not uniform even in the small change of the injection air injected from the air injection pipe 108, the weft remaining from the end of the injection nozzle 102 is left too long or vice versa too much. Due to the withdrawal, there was a problem that the weft comes out of the spray nozzle.

In addition, since the air injected from the air injector 108 is exhausted to the interior of the factory without any measures, the temperature and humidity of the room and the radiation agent, solid powder, etc. attached to the wefts of the surrounding devices accumulate, causing frequent failures. In addition, there were problems such as having to clean as much as that.

This paper proposes to correct the above-mentioned drawbacks. In the loom for supplying the weft yarn by using the injection of the fluid, such as a water jet loom or the air jet loom, the weft cut after the completion of the inlet is always appropriate from the tip of the injection nozzle. Only the length remains so that the ideal position is achieved.

In order to achieve the above object, the present invention is provided with a weft station outlet between the weft wave district and the injection nozzle, but by means of suctioning air by means of suction to draw back the weft yarn at the weft station outlet, the weft yarn is configured to be sucked into the reverse outlet. .

At this time, as the suction method of the weft, the suction pipe is formed by connecting the suction hose to one side of the weft-seat outlet so that the air is sucked through the suction pipe, and the suction pipe is inserted into the insertion hole by being configured to be connected to the insertion hole configured on one side of the suction pipe. Allow the inlet air to be sucked into the suction tube.

The suction hole is installed by inserting a plurality of through-hole guides, the guide is configured to adjust the installation position according to the weft and length to be drawn out.

Therefore, when the weft yarn entered between the inclined openings is cut for the cutting machine after the weaving is completed, the weft yarn is sucked by the suction force of the air sucked into the guide port, so that the weft yarn long exposed to the distal end of the injection nozzle is drawn back out. Since the weft of the appropriate length is left on the tip portion is to ensure the ideal indentation.

Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is an exploded perspective view of the weft-seat outlet 2, in which the suction pipe 6 is projected on one side of the main body 4, and a hollow portion 8 formed in the suction pipe 6 passes through the main body 4. The suction hole 10 penetrating the main body 4 is formed on one side of the suction pipe body 6.

Guide grooves 12 are formed at the left and right sides of the suction hole 10, and the guide yarns 14 are fitted into the guide grooves 12.

The shaft bar 18 of the adjusting knob 16 is inserted into the side of the main body 4 so as to penetrate laterally, and the shaft bar 18 penetrates through the hollow part 8 and is located at the hollow part 8. On the shaft 18 is fixed to the adjustment disk 20, which allows to adjust the suction amount of air by screwing with a bolt (22).

Guide holes 24 are inserted into the suction holes 10 formed through the main body 4 at one side of the suction pipe 6, and a plurality of through holes 26 are formed at the lower end of the guide holes 24. On the upper side, the locking piece 28 is bent.

One side of the suction hole 10 formed in the main body 4 is installed by drilling a screw hole 30, and the guide bolt on the upper end of the wrench bolt 32 by screwing the wrench bolt 32 to the screw hole 30 The locking piece 28 of 24 is settled so that the position of the guide opening 24 can be adjusted by adjustment of the wrench bolt 32.

The lower end of the main body 4 is configured to form an air conveyance path by the concave inlet portion 34 while fixing the tight plate (36) composed of the concave inlet portion 34 with the bolt 38.

Reference numeral 40 is a fixed piece, 42 is a gripper, 44 is a spray nozzle, 46 is a weft yarn, 48 is a warp yarn, 50 is a body, and 52 is a cutter.

In this manner, the present invention constructed as shown in FIG. 4 is installed between the injection nozzle 44 and the gripper 42 formed on one side of the loom of the loom as shown in FIG. It is the same as in the prior art that only the weft thread 46 of the appropriate length is left from the tip of the nozzle 44 so that the next indentation is made more ideal. However, the weft area outlet 2 of the present invention retracts the weft thread 46. Not only does the weft 46 entangle in the reverse outlet 2 in the process, but the length of the reverse draw is always constant, and the length of the reverse weft is adjusted arbitrarily, in which case the suction pipe (6) On the suction hose (not shown) is used to connect.

In the above state, the weft yarn 46 is completed through the injection nozzle 44 between the openings of the inclined 48, and then the body 50 is advanced so that the weft yarn 46, which is inflated, is moved forward to the direct position.

At this time, the weft thread 46 is a state that is drawn out for a long time immediately before the front end of the injection nozzle 44 fixed to one side of the loom, the weft yarn is cut by the cutter 52 in this state.

The weft thread 46 cut by the cutter 52 as above does not remain at the distal end of the injection nozzle 44 and is guided in which the weft thread is inserted into the suction hole 10 as shown in FIG. 5 by the suction force of air. Since the end surface of the weft yarn 44, which is long exposed to the distal end portion of the injection nozzle 44, is drawn back toward the injection nozzle 44, and thus is positioned to be adsorbed to the bottom surface of the injection nozzle 44, thus the Since the tip is exposed for a long time, it is possible to prevent entanglement of the weft caused by the weft.

As the means for retracting the weft 46 in the above, it is composed of an air suction type instead of an air injection type, so that the weft yarn 46 is entangled by the vortex of air as in the prior art, or the length of the weft yarn which does not become constant in the reverse drawing There will be no.

If you want to adjust the reverse draw length of the weft in use, as shown in Figure 3 by rotating the wrench bolt 32 screwed to one side screw hole 30 of the suction hole 10 of the main body 4 wrench wrench bolt By adjusting the height of (32), it is possible to adjust the length of the reverse drawing of the weft.

In other words, when the height of the wrench bolt 32 is rotated to adjust the height, the guide hole 24 inserted into the suction hole 10 by the engaging piece 28 of the guide hole 24 in contact with the upper end of the wrench bolt 32 is fixed. The height of is increased by that much, so the length of the back weft is shortened by that amount.

Contrary to the above, when the reverse draw length of the weft thread 46 is to be adjusted for a long time, the wrench bolt 32 is rotated so that the wrench bolt 32 is screwed into the screw hole 30 to protrude from the main body 4. When the length of the wrench bolt 32 is shortened, the guide hole 24 is deeply inserted into the suction hole 10, and thus, the reverse drawing length of the weft thread is longer.

At this time, the adjustment disc 20 located in the hollow portion 10 is configured to be rotatable by the handle 16 and can adjust the amount of air sucked into the suction hole 20 by the rotation of the adjustment disc 20. .

Therefore, the present invention connects the suction hose to the suction pipe body 6 protruding on one side of the main body 4 so that the air is sucked through the suction pipe body 6 so that the air in the room is sucked as shown in FIG. As it is sucked into and exhausted through the hollow portion 8 of the suction pipe 6, it prevents the weft of the weft due to the vortex phenomenon as in the prior art, and since the uniform suction is always made, the length of the reversed weft is constant, Since it is a suction type instead of a spray type, there is an effect such that a great problem is not caused even in adjusting the temperature and humidity of the indoor room.
