    APPARATUS OF AN AIR JET WORKING MACHINE FOR APPLYING A VOLTAGE ON A FRAME WIRE
    BASIS OF THE INVENTION
    The present invention relates to an apparatus of an air jet type loom for applying tension to a weft yarn, wherein the end of an inserted weft yarn is guided and held in a tube capturing weft yarn by a stream of air directed from a drawing nozzle.
    In an air-jet type loom, a tensioning apparatus is used on the weft yarn, which grasps the end of an inserted weft yarn and the tension of the weft yarn is kept intact by packing. in the absence of relaxation. Japanese Patent Application Publication H4-308252 discloses a weft drawing apparatus including a drawing nozzle and a blowing device which are arranged at the end of a comb of the loom. . The drawing nozzle has a weft guide duct and the blower withdraws the weft yarn from the weft guide duct of the drawing nozzle. The weft wire drawing apparatus is mounted at the end of the comb and has a passageway which extends to an extension portion of a weft carrying conduit carrying a wire. frame.
    The drawing nozzle includes the weft guide duct and a blast nozzle which produces a flow of air in the weft guide duct. The blowing device is disposed on the rear wall of the passage duct at a location adjacent to the entrance of the weft guide duct and blows a stream of air towards the edge of a woven fabric. from the back of the weft guide duct, thereby to apply an appropriate tension on the remaining end of the weft yarn. When a weft yarn is inserted into a warp shed, the remaining end of the weft yarn is blown into the weft guide duct by the flow of air from the drawing nozzle. When the flap of the loom moves backward after tamping, the activation of the drawing nozzle is stopped and the blower is activated. The blower blows a stream of air to blow out the remaining end of the weft yarn from the weft guide duct.
    In the weft-drawing apparatus disclosed in the above-mentioned publication having a structure in which the drawing nozzle and the blowing device are arranged on a block-shaped member and in which the passage duct is disposed on the extension of the weft transport duct at the end of the comb, the air flow in the blowing device is blown into an open space, so that the air tends to spread. Such air diffusion reduces the force exerted on the remaining end of the weft yarn and may give rise to a risk of failure in extracting the remaining end of the weft yarn in the weft yarn guide duct of the drawing nozzle.
    In addition, the weft drawing apparatus disclosed in the above mentioned publication, which is mounted on the comb at the end of the latter can not be applied to what is called a comb. of the "non-cut" type which makes it possible to adjust the weaving width of the loom without having to cut the comb having the weft conveyor. In other words, the loom equipped with the weft stretching machine has a so-called cutter comb which uses a comb for each different weaving width of the loom and the block-shaped element can be mounted at the end of the comb.
    The present invention relates to providing an apparatus in an air jet type loom for applying tension to a weft yarn, which allows the end of a yarn to be pulled out quickly. inserted weft, captured in a weft capture tube, from the weft capture tube after compaction by the comb.

    DETAILED DESCRIPTION OF THE EMBODIMENTS
    First embodiment
    Hereinafter there is described a first embodiment of an apparatus of an air jet type loom for applying tension to a weft yarn according to the present invention with reference to FIGS. FIG. 1 shows the bottom portion of the air jet type loom in which the Y1 end of a weft yarn Y is inserted. A wing 1 is attached to a link of the wing IA (FIG. as can be seen in Figure 4) which is in turn fixed to a locking shaft (which is not shown in the drawing) to be able to oscillate in concert. A comb 2 is attached to the wing 1 and includes a number of teeth 2A. Each tooth 2A has a recess and the recesses of the teeth 2A of the comb 2 which are juxtaposed in the weft insertion direction of the air jet type loom co-operate to form a guide passage 4 for the wire. weft, which is open on a pick line. The loom is configured to adjust the width of the fabric without having to cut the comb 2. A device acting as a templet 7 is arranged in such a manner that it extends over a selvedge 6 and over it. adjacent side of the fabric 5.
    The weft yarn Y is cut at a location adjacent to its front end by a blade 8 which is disposed between the fabric 5 and the selvedge 6 when the front end of the weft yarn Y is passed in front of the device 7 serving as the templet and is located between the fabric 5 and the edge 6. Several secondary nozzles 9 to facilitate the flight of the weft thread through a crowd and a weft feeler 10 to detect the arrival of an inserted weft thread at the feeler 10 of the weft thread are fixed to the leaf 1. The weft threader 17 is disposed between the fabric 5 and the edge 6. The reference numerals 11, 12 denote the warp thread and the edge thread, respectively.
    An apparatus 13 for applying a tension on the weft yarn is disposed on the flapper 1 at a downstream location with respect to the edge 6. The apparatus 13 for applying a tension on the weft yarn includes a nozzle stretching 14 which is arranged on the front side of the comb 2 or on the fabric winding side with respect to the comb 2, a weft capture tube 15 which is arranged on the rear side of the comb 2 or on the unwinding side of the warp yarn with respect to the comb 2, and a weft extraction nozzle 16.
    As shown in FIG. 4, the drawing nozzle 14 has an injection hole 14A which faces the weft guide 4 and is attached to the leaf 1 at its base 19 by a bolt 18 inserted through the base 19 and in a slot T of the wing 1 and a nut 20. When the nut 20 is loosened, the drawing nozzle 14 can move in the direction of the weaving width of the loom to adjust its position mounting. An air supply tube 21 is connected to the lower end of the drawing nozzle 14 for supplying air from an air source (not shown in the drawing) via a switching valve. (which is not represented in the drawing). The switching valve is actuated to allow the drawing nozzle 14 to direct a flow of air from the injection hole 14A for a predetermined period of time between the moment immediately preceding the completion of the insertion of the weft yarn and the moment corresponding to the compaction of the comb so as to guide the end Y1 of the weft yarn Y in the weft capture tube 15.
    Referring to FIGS. 2 to 5, an L-shaped support 22 serving as a support member is arranged on the rear surface of the comb 2. A horizontal portion 23 of the L-shaped support 22 is permanently mounted on the upper surface of the leaf 1 by means of bolts 24. A vertical portion 25 of the L-shaped support 22 is arranged to extend parallel to the comb 2. When the bolts 24 are loosened, the support 22 can move in the weaving width direction of the loom to adjust the mounting position of the support 22. The vertical portion 25 does not necessarily extend parallel to the comb 2, but may be inclined with respect to the comb 2.
    As shown in FIG. 5, the weft capture tube 15 is attached to the vertical portion 25 of the support 22 by means of a metal connector 26. The weft capture tube 15 has a configuration wherein the short cylinder 27 is disposed substantially at the weft guide guide passage 4 of the comb 2. The short cylinder 27 has at its end an inlet port 15A which is open on the rear side of the comb 2. The inlet 15A of the short cylinder 27 faces the injection hole 14A of the drawing nozzle 14, from which a flow of air is directed. The end of the long cylinder 28 extends in the weaving width direction of the air jet type loom and is open.
    A pair of opening pins 29 is mounted on the vertical portion 25 of the carrier 22 at mutually overlapping locations and through the inlet port 15A of the weft capture tube 15 (as can be seen in FIGS. Figures 2 to 4). The pair of opening pins 29 extends towards the rear surface of the comb 2 and is inserted between two adjacent teeth 2A to thereby open the teeth 2A by separating them reciprocally to obtain a free space between them. The inlet 15A of the weft capture tube 15 is open on the space between the two adjacent teeth 2A opened by reciprocal spacing via the opening pins 29.
    A weft extraction nozzle 16 is mounted on the vertical portion 25 of the support 22 via a metal connector 30 at a location upstream of the short cylinder 27 of the weft capture tube 15 when viewed in the insertion direction of the weft thread. The weft extraction nozzle 16 has an injection hole 16A which is open on the space between the two adjacent teeth 2A. The mounting position of the weft extraction nozzle 16 is set at a position which corresponds to the height of the Y1 end of a weft yarn extending between the selvedge 6 and the capture tube weft yarn 15 during compaction by the comb 2. The gap between the two adjacent teeth 2A which faces the injection hole 16A of the weft extraction nozzle 16 does not is not influenced by the opening of the teeth by the opening pins 29. The rear end of the weft extraction nozzle 16 is connected via the metal connector 31 to an air supply tube 32. The air supply tube 32 is connected via a switching valve (not shown in the drawings) to a source of air. The switching valve is set to be activated for a predetermined period of time after a packing operation so that the weft extracting nozzle 16 directs a flow of air from the injection hole 16A. up to the end Y1 of the weft yarn Y after the compaction. Since the weft capture tube 15 and the weft extraction nozzle 16 are attached to the leaf 1 via the common support 22, the weft capture tube 15 and the weft extraction tube 16 weft yarn 16 can move together, which facilitates adjustment of the weaving width of the loom.
    Hereinafter will be described the operation of the apparatus 13 for applying a voltage on the weft yarn. Referring to Figure 1, the drawing nozzle 14 is activated to direct a flow of air from the injection hole 14A before the completion of weft insertion. The air directed from the drawing nozzle 14 flows through the weft guide 4 and through the open space through the cover pins 29 between the two adjacent teeth 2A and enters the weft capture tube 15 through the inlet 15A, as indicated by the arrow shown in Figure 1.
    When the insertion of the weft yarn has come to an end, the end Y1 of the weft yarn Y which has reached the location where the drawing nozzle 14 is located is guided in the inlet port 15A of the tube for capturing weft thread 15 by the flow of air directed from the injection hole 14A of the drawing nozzle 14. The end Y1 of the weft yarn Y is held firmly by forming a curve between the short cylinder 27 and the long cylinder 28 of the weft capture tube 15.
    After completion of the weft insertion, the Y1 end of the inserted weft yarn Y is held firmly in the weft capture tube 15 by the flow of air directed from the injection hole 14A of the drawing nozzle 14, so that the Y weft yarn is packed, while being under tension. When the leaf 1 begins to move back after the settlement, the drawing nozzle 14 terminates the air injection and simultaneously the weft extraction nozzle 16 starts to direct the air. Since the flow of air directed from the injection hole 16A of the weft extraction nozzle 16 passes through the space between the two adjacent teeth 2A, the direction of flow of the air passing through the space between the two adjacent teeth 2A is straightened and the air flows in a laminar state having a strong directionality. Thus, the flow of air directed from the injection hole 16A of the weft extraction nozzle 16 acts on the weft Y yarn appropriately regardless of the variation in the height of the yarn. Y weft extending between the weft capture tube 15 and the selvedge 6, so that the Y1 end of the weft yarn Y is extracted from the weft capture tube 15 in a successful manner .
    In the first embodiment, the flow of air directed from the injection hole 16A of the weft extraction nozzle 16 and passing through the space between the two adjacent teeth 2A in a laminar state and with a strong directionality can be accurately blown against the yarn end Y1 Y extending between the selvedge 6 and the weft capture tube 15. In addition, the structure by which the extraction nozzle weft yarn 16 is disposed on the rear side of the comb 2 allows to direct a flow of air just after the activation of the compaction of the comb, so that the weft yarn can be extracted from the weft capture tube 15 promptly and safely.
    In addition, the provision of the weft extraction nozzle 16 behind the comb 2 does not require a large space for the assembly of the weft extraction nozzle 16. Therefore, the wire capture tube weft 15 may be disposed at a location adjacent the support 22 on which the weft capture tube 15 is mounted and accordingly the length between the fabric 5 and the drawing nozzle 14 can be shortened Thus, it is possible to shorten the length between the selvedge 6 and the Y1 end of the weft yarn extending between the selvedge 6 and the weft capture tube 15, in such a way as to prevent wastage. Weighing yarn Y. Since the injection hole 14A of the drawing nozzle 14 directly faces the Y1 end of the weft yarn Y and since the inlet port 15A of the capture tube of weft yarn 15 is arranged in the space provided between the two adjacent teeth 2, 1 The Y1 end of the weft yarn Y is guided in a successful manner in the weft capture tube 15.
    Second embodiment
    Hereinafter, a second embodiment according to the present invention will be described with reference to Figs. 6A and 6B. In the drawings and in the following description of the second embodiment, the same reference numerals are used for elements or for common components in the first and second embodiments, and the detailed description of said elements or said elements will be omitted. components. The second embodiment differs from the first embodiment with respect to the mounting structure of the weft extraction nozzle 16. Specifically, a mounting plate 33 is used which has a rectangular configuration to make as a support member in addition to the L-shaped support 22 on which the weft capture tube 15 is mounted. The mounting plate 33 has a U-shaped holding portion 33A obtained therefrom. bending a portion of the mounting plate 33. The mounting plate 33 is attached to the upper frame 2B of the comb 2 with a bolt 34 at a location adjacent to the vertical portion 27 of the bracket 22, the U-shaped holding portion 33A of the mounting plate 33 being mounted to cover a portion of the top frame 2B of the comb 2.
    The weft extraction nozzle 16 is mounted on the mounting plate 33 at one of its ends at a location where the injection hole 16A of the weft extraction nozzle 16 faces the end. Y1 of the weft yarn Y extending between the selvedge 6 and the weft capture tube 15. The weft extraction nozzle 16 is fixed to the mounting plate 33 via the metal connector 31. The operation the weft capture tube 15 and the lead tube of the weft extraction nozzle 16 are substantially identical to those of the first embodiment and therefore their description will be omitted. Since the weft capture tube 15 and the weft extraction tube 16 are mounted on the leaf 1 via two independent members, specifically the support 22 and the mounting plate 33, respectively, the positions the weft capture tube 15 and the weft extraction nozzle 16 are interchangeable by adjustment according to the weaving conditions.
    The second embodiment which uses the mounting plate 33 having a simple configuration is advantageous because the weft extraction nozzle 16 can be mounted easily and also because the yarn end Y1 of the weft yarn Y is extracted from the weft capture tube 15 in a successful manner, as was the case in the first embodiment. An air jet type loom may have an element that prevents vibration of a tooth 2A at the location corresponding to the weft feeler 10. By forming a mounting hole through the element In question, the element can be used as a mounting plate, in the same way as the mounting plate 33, on which the weft extraction nozzle 16 can be mounted.
    Third embodiment
    Hereinafter, a third embodiment will be described in accordance with the present invention with reference to Fig. 7. In the drawings and in the following description of the third embodiment, the same reference numerals are used for common elements. and for common components in the first and third embodiments, and the description of said elements or said components will be omitted. In the third embodiment, the apparatus 13 for applying tension to the weft yarn is used in an air-jet type loom which has a tuck edge selector 35.
    The tuck edge forming device 35 is a known structure which includes a device body 36 having a tuck-in needle (not shown) which is disposed adjacent to the side of the fabric which is adjacent to the drawing nozzle 14. The tuck edge forming device 35 further includes a suction pipe 37 which is disposed between the device body 36 and the drawing nozzle 14 on the outside of the fabric 5. The suction pipe 37 has a suction hole 37A which is open on the weft guide channel 4. The drawing nozzle 14 and the weft capture tube 15 of the apparatus 13 for applying a voltage on the weft thread have the same structure as that of their equivalents of the first embodiment. The drawing nozzle 14 is disposed on the front side of the weft guide passage 4. The weft capture tube 15 is arranged on the rear side of the comb 2 in face-to-face connection with the nozzle drawing 14.
    The weft extraction nozzle 16 has the same structure as that of its equivalent of the second embodiment and is mounted on the mounting plate 33 disposed on the rear side of the comb 2 between the warp threads 11 and the weft capture tube 15. The injection hole 16A of the weft extraction nozzle 16 faces the suction hole 37A of the suction pipe 37 through the space between the two teeth 2A of the comb 2. A feeler of weft yarn 17 is arranged on the front side of the comb 2 between the drawing nozzle 14 and the suction pipe 37.
    When the air jet type loom is put into operation, the end Y1 of an inserted weft yarn Y is drawn into the weft capture tube 15 via a flow of air directed to from the drawing nozzle 14 and the weft yarn Y is packed while being under tension. When the leaf 1 is withdrawn, the injection of a stream of air from the drawing nozzle 14 stops and simultaneously, a flow of air is directed from the extraction nozzle of weft yarn 16 for extracting the Y1 end of the weft yarn from the weft capture tube 15. The Y1 end of the weft yarn Y is blown down towards the suction pipe 37 by a flow of air directed by the weft extraction nozzle 16 and is then drawn into the suction pipe 37 through its suction hole 37A via suction air created in the pipe of suction 37. In the suction pipe tube 37, the air flow force directed by the weft extraction nozzle 16 is added to the suction force of the air created in the suction pipe 37, this addition resulting in that we obtain an intense suction force, which allows to firmly hold the end Y1 of the wire of Y frame.
    In the third embodiment in which the weft extraction nozzle 16 is arranged facing the suction pipe 37, the flow of air directed by the weft extraction nozzle 16 facilitates the blowing the Y1 end of the weft yarn Y into the suction hole 37A of the suction pipe 37. The flow of air directed by the weft extraction nozzle 16 facilitates the increase of the weft yarn. air suction force in the suction pipe 37, which improves the state of the end Y1 Y weft yarn which is held firmly during the formation of the selvedge selvedge.
    The present invention is not limited to the embodiments described above. It can be implemented in various alternative embodiments, as illustrated by way of example below.
