The present invention relates to an apparatus for stabilizing weft loading in a water jet loom.

In a water jet loom that uses pressurized water as the weft wetting fluid, there is a phenomenon that the water sprayed for weft weaving moves upward as it goes to the semi-finished yarn side. This phenomenon is presumed to cause an upward airflow in the wefting space in front of the body when the body in which a plurality of body wings are arranged in parallel with the upper and lower clasps performs a rocking motion.

The reason why the upward air flow occurs is that when the body retreats after the body stroke, the air on the cloth fell side is attracted by the body, and when the body continues to advance, the drawn air is closed by the body. It can be thought of as being pushed back and rising.

The rising movement phenomenon of the water sprayed as mentioned above is easy to generate | occur | produce at the time of a high speed operation, a water saving operation, etc. If such water is injected upwardly obliquely, the warp is damaged or the wefting becomes unstable by the upwardly sprayed water.

As a technique for preventing the upward movement phenomenon of the water injected as described above, there is a weft stabilization device described in Patent Document 1.

[Patent Document 1]

Japanese Patent Publication No. 2004-124318

The conventional weft stabilizing device includes an airflow suppressing member that protrudes toward the cloth pel outside the inclined opening and extends in the weft direction, and includes a clasp or a body above or below the body. It is provided in the upper or lower part of the body holding member held in a slay. As a result, the rise of the air in the wefting space in the inclined opening is suppressed by the airflow suppressing member, and the rising movement phenomenon of the injected water is suppressed.

However, in the conventional weft stabilization device, during wefting during the swinging of the body, the actual weft non-perforation line moves in the inclined movement direction, and the wefting is not stabilized. Cause.

As for the change of the actual weft non-woven line as described above, when the body is retracted (the main shaft angle is 0 ° to 180 °), the weft space becomes negative pressure, and the actual weft non-woven line moves to the body side. It can be considered that the weft insertion space is pressurized when the weft advances (the main shaft angle is 180 ° to 0 °), and the actual weft non-woven line moves to the cloth pel.

An object of the present invention is to stabilize the actual weft non-working line by suppressing fluctuations in air pressure in the wefting space.

The weaving stabilization device of the water-jet loom according to the present invention is provided with at least one of the upper side and the lower side of the body to protrude toward the cloth pel outside the inclined opening range and to extend in the wefting direction.

One weft stabilizing device according to the present invention forms a gap between at least one of the above and below the member and the body holding member to be held in the body or the slay.

In the other weft stabilizing device according to the present invention, at least one of the members above the upper part and the lower part forms a hole in a position on the body side.

In another weft stabilizing device according to the present invention, at least one of the members above and below the bottom forms a missing portion toward the cloth pel.

In the weft stabilization device, by forming at least one of a gap, a hole, and a missing portion, it is possible to suppress fluctuations in the air pressure in the weft space in the formed location, and the actual weft non-periphery line moves in the direction of movement of the warp yarn. Can be prevented. The details are as follows.

When the body is retracted, air outside the wefting space is put into the wefting space through a gap, a hole or a missing portion, so that the wefting space is prevented from negative pressure, and when the body is advanced, the air in the wefting space is By escaping from the wefting space to the outside through a gap, a hole or a missing part, pressurization of the wefting space is suppressed.

As a result, since fluctuations in the air pressure in the wefting space are suppressed, the occurrence of the raised airflow at the time of the original body stroke is suppressed, and the change in the airflow in the inclined movement direction is suppressed. As a result, the actual weft non-woven line is very stabilized, and the number of stops of the loom decreases.

The weft stabilization device may further include a vent opening that is opened to the rear side of the body and is connected to the upper gap or hole in series. By doing so, since the vent is opened to the rear of the body, air outside the inclined opening is actively and efficiently put into the wefting space when the body is retracted, and the actual weft non-woven line is more stabilized.

The length dimension of the inclination direction of at least one of the said upper part and the said lower part may differ according to the location in the weft insertion direction, and the magnitude | size of the said clearance gap or the said hole of at least one of the said upper part and the said lower part WHEREIN: The magnitude | size in the said inclination direction may differ according to the location to the weft insertion direction.

Instead of the above, the position in the inclined movement direction of the front end edge on the cloth pel side in the front end edge of at least one of the above and the bottom members may vary depending on the location in the weft insertion direction.

In any of the above cases, at least one of the upper member and the lower member may include a plurality of pieces disposed adjacent to the wefting direction.

By varying the position in the oblique movement direction of the front end edge of at least one of the members of the cloth in accordance with the location in the weft insertion direction, the missing portion at the location increases as the position becomes more body side. The larger the missing part is, the larger the amount of airflow passes, so that a small amount of upward airflow can be generated.

In actual weft weaving, as the weft yarn moves to the semi-finished side, the non-main power falls, and the weft yarn tends to move downward due to gravity. However, if the member is subjected to conditions such as the size of the missing portion or the gap or the hole due to the length dimension or position as described above, the member is raised by changing the condition according to the passing range of the weft yarn at the time of advancing the body. The airflow is generated a little, and the weft of the weft is suppressed downward, and the actual weft non-visiting line is further stabilized.

The change of the condition may, for example, shorten the length dimension of the member in the direction of inclination of movement, increase the missing portion with the position in the direction of inclination of the leading edge of the member as the body side, or This can be done by reducing the size of the gap or the hole, such as by increasing the location of the semi-finished yarn side and the rising airflow in the wefting space.

EXAMPLE

[Example of Water Spray Loom]

1 to 3, the water jet loom 10 is arranged in parallel to each of the plurality of heald frames 14 through a plurality of inclinations 12 released from the inclined beam not shown in the form of a sheet. The inclined 12 is moved up and down to form the inclined opening 18 by moving the heald frame 14 up and down in the form of one-to-one through the several heald 16 supported by the above.

The weft yarn (not shown) is located while the body 20 is located on the upstream side (the light frame 14 side) in the moving direction (that is, the front-rear direction) of the inclination 12 from the weft injector 22. , It is sprayed together with water pressurized from the weft injecting nozzle 22 and wefted into the weft enclosing space 24 (see FIG. 3) in the inclined opening 18.

The weft yarn which was wefted impinges on the cloth pel 26 by the body 20, and is woven into the woven fabric 28. As the woven fabric 28 is woven, the woven fabric 28 is wound around a cloth winding beam (not shown) through the plurality of guide rolls 30.

The body 20 supports the plurality of body wings 32 in parallel with the upper and lower clasps (ie, clasp portions) 34 and 36, and the plurality of body holding members in the lower clasp 36. 38 and a plurality of screw members 40 are attached to the upper end of the slay 42 in a relatively non-movable manner.

The slay 42 is attached to the rocking shaft 44 which extends the lower part thereof in the weft insertion direction so that it cannot move relatively. The swing shaft 44 swings around an axis line extending in the weft insertion direction in synchronization with the rotation of the main shaft of the loom 10. As a result, the body 20 is oscillated around the axis of the oscillation shaft 44 to perform a body stroke motion.

The water injected from the weft injector nozzle 22 is downstream by the front shield plate (i.e., the fixed cover 46) and the splash guide (i.e. the movable cover) 48 (i.e., downstream in the direction of movement of the inclination 12). Scattering from the sides and upwards is suppressed.

The front shield plate 46 extends above the one guide roll 30 in the weft direction (i.e., in the width direction and the left and right directions), and also the left and right loom frames (not shown) with respect to the left and right ends. Not attached).

The splash guide 48 extends in the weft direction in a state in which the inclined opening 18 and the guide roll 30 on one side cover the inclined 12 and the space above the woven fabric so as to be openable. have.

The splash guide 48 is rotatably supported by the support shaft 50 extending upward of the inclination 12 in the weft direction, and also in the moving direction of the inclination 12 (that is, in the inclined movement direction). The downstream end side of the front side is brought into contact with the front shield plate 46. For this reason, the splash guide 48 can open and close the upper space of the area | region before and behind the cloth pell 26 by rotating this at an angle around the axis line of the support shaft 50. As shown in FIG.

[First Embodiment of Weft Intake Stabilizer]

The weft stabilization device is a pair of airflow control members 52 attached to the upper clasp 34 and the lower body retaining member 38 at the bottom of the cloth pel from the lower side so as to suppress the fluctuation of the airflow in the inclined opening 18. And 54).

The two airflow suppressing members 52 and 54 are made of a plate member, and protrude from the upper clasp 34 and the lower body retaining member 38 toward the cloth pel 26 to the cloth pel 26, respectively. The outside of the inclined opening 18 extends continuously throughout the weft insertion direction.

The upper airflow suppressing member 52 has a Z-shaped longitudinal cross-sectional shape and a plurality of screws toward the cloth pel 26 of the upper clasp 34 so as to cover the upper space of the inclined 12 from above. It is attached by the member 56.

The lower airflow suppressing member 54 has a L-shaped longitudinal cross-sectional shape, and the plurality of airflow suppressing members 54 are arranged toward the cloth pel 26 of the lower body retaining member 38 so as to cover the space below the inclined 12 from below. It is attached by the screw member 58 of this.

A plurality of spacers 60 supported by the screw member 56 are disposed between the airflow suppressing member 52 and the clasp 34. For this reason, the weft stabilization device has a plurality of gaps 62 extending in the weft direction between the body and the attachment surface formed by bending the end of the airflow control member 52 and the attachment surface of the clasp 34. It is provided near (20).

Such a clearance 62 is a space which connects the upper and lower spaces of the airflow suppression member 52 successively, and permits the passage of air in the upper and lower spaces of the airflow suppression member 52. The plurality of gaps 62 adjacent to the weft insertion direction are partitioned from each other by the spacer 60 (see FIG. 2). In the example shown, the width dimensions of the gap 62 in the oblique moving direction are the same.

As described above, the airflow inhibiting members 52 and 54, which protrude toward the cloth pel 26 outside the inclined opening 18 and extend in the weft inlet direction, respectively, are provided with the clasp 34 and the body holding of the body 20, respectively. If provided in the member 38, the rise of the air in the inclined opening 18 is suppressed by the airflow suppressing members 52 and 54, and the rising movement phenomenon of the water injected from the weft injecting nozzle 22 is suppressed. do.

In addition, if the clearance 62 is provided between the clasp 34 and the airflow suppressing member 52, first, when the body 20 shown by the arrow 64 in FIG. 3 is retracted (the main shaft angle is in the range of 0 ° to 180 °) ), The air in the weft space 24 is pulled toward the body 20, so that the weft space 24 is in a negative pressure state. At this time, however, the air in the upper space of the body 20 flows like the arrow 66 and is inserted into the inclined opening 18, particularly the wefting space 24, through the gap 62. This suppresses the weft filling space 24 from being in a negative pressure state.

On the other hand, when advancing the body 20 (when the main axis angle is in the range of 180 ° to 0 °), the air in the wefting space 24 is pushed toward the cloth pel 26 by the body 20, and wefting The space 24 is in a pressurized state. However, at this time, since the air in the inclined opening 18, in particular, the wefting space 24 escapes through the gap 62 to the space above the body 20, the wefting space 24 becomes pressurized. Is suppressed.

As a result, since the fluctuations in the air pressure in the wefting space 24 are suppressed, while the occurrence of the rise airflow at the time of body stroke in the prior art is suppressed, the fluctuations in the air pressure in the inclined movement direction are suppressed, and as a result, the actual weft runaway The line is very stable, reducing the number of stops of the loom.

[Second embodiment of weft intake stabilization device]

In the weft stabilizing device shown in FIG. 4, the airflow suppressing member 52 is integrally and continuously provided with a restraining portion 70 having its original function and an upper end of the restraining portion 70. It includes a bent portion 72 folded back from the top to the back. The bending part 72 forms the vent 74 which opens to the back of the body 20, and connects through the clearance 62.

Similar to the weft stabilization device shown in FIG. 4, even when the vent hole 74 is opened to the rear of the body 20, the body 20 is retracted in the direction indicated by the arrow 64, and the direction opposite thereto. Upon advancing the body 20 into the furnace, the wefting spaces 24 respectively become a negative pressure state and a pressurized state in theory.

However, when the body 20 is retracted, air outside the inclined opening 18 is inserted into the wefting space 24 more actively and efficiently than the first embodiment by the air vent 72 opening behind the body 20. Lose. As a result, the weft filling space 24 is suppressed more reliably in the negative pressure state.

In addition, when the body 20 is advanced, the pressure in the weft space 24 is pushed by the vent hole 74 in which the air in the inclined opening 18, in particular, the weft space 24 opens to the rear of the body 20. The state can be suppressed and the rise airflow can be suppressed in the same manner as in the case where the gap 62 is not present. Thereby, since the upper part of the body 20 is not directly opened, generation | occurrence | production of the airflow by the clearance 62 is suppressed.

Moreover, since the bend part 72 is provided and the inflow efficiency of air rises, the clearance 62 can be made small. In addition, since the air gap in the inclined opening 18 becomes difficult to escape from the weft insertion space 24 by making the clearance 62 small, the omission of the air flow at the time of advancing the body 20 is suppressed to the minimum. .

As a result, in the second embodiment shown in Fig. 4, fluctuations in the air flow in the inclined movement direction are suppressed, and the actual weft non-woven line is very stabilized.

[Third embodiment of weft stabilization device]

In the weft stabilization device shown in FIG. 5, a plurality of spacers 60 are disposed between the attachment surface of the lower body holding member 38 and the attachment surface of the lower airflow suppressing member 54 folded and bent, A plurality of gaps 62 are formed on the lower side of the airflow suppressing member 54. The lower airflow suppressing member 54 may be attached to the body 20, specifically the clasp 36.

In the third embodiment, the gap 62 in which air outside the inclined opening 18 and in the inclined opening 18 is lowered at the time of advancing and retracting the body 20 in the direction of the arrow 76 and the opposite direction thereof, respectively. In the direction of arrow 78 and the opposite direction. As a result, the weft filling space 24 is suppressed from being in a pressurized state and a negative pressure state, and the actual weft auxiliary line is very stabilized.

[Fourth embodiment of weft intake stabilization device]

In the weft stabilization device shown in FIG. 6, a plurality of gaps 62 are formed in each of the upper and lower airflow suppressing members 52 and 54 in combination with the second and third embodiments. Also in the fourth embodiment, the negative pressure state and the pressurized state of the weft inlet space 24 are suppressed as in the first to third embodiments described above, and the actual weft non-woven line is very stabilized.

[Fifth Embodiment of Weft Intake Stabilization Device]

As an example in FIG. 7, instead of the gap 62 in the first to fourth embodiments, a plurality of holes 80 may be formed in at least one of the upper and lower airflow suppressing members 52 and 54.

For example, in the example shown in FIG. 7, instead of the gap 62 in the first embodiment, the plurality of holes 80 are located at a position close to the body 20 of the upper airflow control member 52. Forming. In this example, the cutout portion and the clasp 34 are formed when the cutoff portion is formed on the attachment side of the body 20 of the airflow suppression member 52 and the airflow suppression member 52 is attached to the clasp 34. The enclosed part of the wire was used as the hole 80. Thereby, it can be said that the hole 80 is formed in the airflow suppressing member 52 substantially. In the example shown in FIG. 7, the shape of each hole 80 is rectangular, but it can be set as suitable shapes, such as a long circle, an ellipse, and a circle.

In the case where the hole 80 is formed in the upper airflow suppressing member 52, the air vent 74 opened to the rear of the body 20 by the bent portion 72 in the third embodiment shown in FIG. You may be installing.

Also in the fifth embodiment, the same effects as in the first to fourth embodiments can be obtained.

In the example shown in FIG. 7, the spacer 60 was not provided. However, in any one of the first to fourth embodiments, in addition to the gap 62, the plurality of holes 80 in the fifth embodiment may be formed in at least one of the upper and lower airflow suppressing members 52 and 54. good.

Instead of forming the cut portions in the airflow suppressing members 52 and 54 as shown in FIG. 7, the holes 80 may be formed in the airflow suppressing members 52 and 54 themselves. In detail, the hole 80 is formed in the area | region on the body side rather than the intermediate position of the airflow suppressing members 52 and 54 in the diagonal direction.

[Sixth Embodiment of Weft Stabilization Device]

As shown in FIG. 8 as an example, also in any one of the above embodiments, the length dimension and the width of the gap 62 or the hole 80 in the inclined movement direction of the airflow suppressing members 52 and 54 above or below. The dimension may be a different value depending on the location in the weft direction.

In the embodiment shown in FIG. 8, each of the airflow suppressing members 52 and 54 has a plurality of pieces 82, 84, 86, and 88 (four in the example shown) arranged adjacent to the weft inlet direction. Include. Weft yarns are wefted from the left in FIG. 8.

The pieces 82 and 84 located on the yarn feeding side (that is, the weft inserting side) form a gap 62 between the pieces of airflow inhibiting members 82 and 84 by the spacer 60. However, the width dimension in the oblique moving direction of the space 62 formed by the piece 82 positioned at the steepest yarn side is larger than that formed by the piece 84. This is implemented by using spacers 60 of different length dimensions.

The pieces 86 and 88 located on the semi-swept side (that is, the anti-swept side = reach side) are provided with the clasp 34 at the upper side and the body holding member at the lower side without using the spacer 60. It is screwed directly to (38).

The length dimensions of the pieces 82, 84, and 86 in the inclined movement direction except for the piece 88 located on the most semi-reflective side are the same. However, the length dimension of the piece 88 in the oblique moving direction is smaller than that of the other pieces 82, 84 and 86. Moreover, the clearance 62 of the piece 84 of the semi-emergency yarn side is smaller than the clearance 62 of the piece 82 of the yarn feeding side.

Since the width dimension of the clearance 62 in the oblique movement direction and the length dimensions of the pieces 82, 84, 86 and 88 are the same as above, from the body 20 (or the body holding member 38) as the oblique movement direction The length dimension of the airflow control member varies depending on the location in the weft direction. In detail, the length dimension and the gap of the piece in the oblique movement direction become smaller as it goes from the yarn feeding side to the semi yarn feeding side.

In other words, the position of the leading edge at the front end side 26 before weaving the airflow inhibiting member varies depending on the location in the weft direction. Specifically, the position is located on the body side as it moves from the yarn feeding side to the semi-emitter side. For this reason, the missing part 90 is formed in the cloth | pel side of the airflow suppressing member of the semi-finished yarn side with respect to the airflow suppressing member of the yarn feeder side, and the missing part 90 becomes larger as for the airflow suppressing member of the semi-emergency yarn side.

When a parallel imaginary line is drawn in the direction in which the body is connected from the position where the distance L1 + L5 from the clasp 34 to the leading edge of the piece 82 where the leading edge of the airflow control member is farthest, The missing space between the virtual line and the position where the distance L2 + L6 from the other region, for example, the clasp 34, to the leading edge of the piece 82 is taken. In this case, the front end portion has a missing portion in the partial region on the cloth pel side of the front end edge of the piece 84 of the distance L2 + L6 whose distance is shorter than the distance L1 + L5.

In the example shown, the length dimensions L1, L2 and L3 of the pieces 82, 84 and 86 are 35 mm respectively, the length dimension L4 of the piece 88 is 25 mm and the width dimensions L5 and L6 of the gaps 62 and 62 respectively. 6mm and 3mm. For this reason, the pieces 82, 84, 86, and 88 protrude toward the cloth pel 26 on the steep side.

That is, in this embodiment, when the body 20 is moved forward and backward, it is divided into two areas in the respective weft passing ranges, and the boundary of such areas, that is, the main axis angle at which the swing direction of the body 20 is reversed is about 180 °. A gap 62 and a hole 80 are formed on the steep side of the boundary with the position as a boundary, and the gap 62 and the hole 80 are made larger as they face the steep side. With the boundary between them, the missing part 90 exists in the semi-finished side of the boundary, and the missing part 90 is made larger as it goes to the semi-finished side.

In the embodiment shown in FIG. 8, the front end of the weft yarn wefted from the yarn feeding side passes through the area of the left half formed by the pieces 82 and 84 at the time of retreat of the body 20 (the first half of the weft yarn). At the time of advancing the body 20 (the second half of wefting), it passes through the area of the right half formed by the pieces 86 and 88.

In general, when the front end of the weft yarn is in the region of the steep yarn side (i.e., the first half region) when the body 20 retreats, the non-weft of the weft yarn is large, but the non-weft of the weft yarn gradually decreases during weft insertion. As a result, when the front end of the weft is reciprocating the area on the side of the semi-finished yarn (i.e., the second half area), since the weft yarn's circumferential velocity decreases due to gravity in the latter half area, the weft position of the weft yarn tends to displace downward. Is in.

However, in the embodiment shown in FIG. 8, the air is inserted into the wefting space 24 from the gap 62, and the front end of the weft thread passes through the front half region by the pieces 82 and 84 on the steep yarn side. The negative pressure in the weft filling space 24 at the time is effectively suppressed. Thereby, as well as the non-ceiling force of the weft yarn is large, the movement to the body 20 side of the weft non-ferrous position is suppressed.

In addition, the fragments 86 and 88 of the latter half region, in which the weft leading edges collide when the body is advanced, do not have a gap 62, and the leading edge of the cloth pel 26 is larger than that of the fragments 82 and 84. It retracts from the cloth pel 26, and the missing part 90 is formed. For this reason, in the latter half region, the rising air in the wefting space 24 is slightly generated, and the weft yarn effectively suppresses the fall of its non-slip position by the rising air.

In the embodiment shown in FIG. 8, the movement toward the body 20 side of the weft non-weapon position is suppressed on the side of the weft yarn, while the rising airflow is controlled on the side of the weft yarn side, and the drop of the weft non-weapon position is suppressed. As a result, the actual weft auxiliary line becomes more stable.

In any of the above embodiments, when the gap 62 or the hole 80 is located at a large distance from the body 20, the air in the inclined opening 18 moves in the gap 62 or the hole 80 when the body is advanced. ), An upward airflow is generated in the weft inlet space 24, and as a result, the actual weft non-working line fluctuates up and down.

In particular, when the gap 62 or the hole 80 is present above the wefting space 24, the weft thread also rises due to the above airflow. For this reason, it is preferable to form the clearance 62 or the hole 80 as close to the body 20 as possible.

In the sixth embodiment, the gap 62 or the hole 80 is not formed, and only the length dimension of the airflow suppressing members 52 or 54 in the inclined movement direction is located in the weft direction. Other values may be used. In addition, the airflow suppressing members 52 or 54 of the upper or lower portions in the weft direction and the inclined movement direction have a length dimension, and the size of the gap 62, the hole 80, and the missing portion 90 is a weft weft. It can adjust according to the flow of air in a space, and the structure of loom (in detail, stroke of a body stroke, weaving width, weft insertion timing, loom rotation speed, etc.).

As mentioned above, the clearance 62 or the hole 80 which allows the movement of the air with respect to the weft filling space 24 may be formed in either of the upper and lower airflow control members 52 and 54, or may be formed in both. good. The size of the gap 62 may be adjustable by changing spacers having different thicknesses, and the size of the hole 80 is overlapped and fixed to the hole 80 so as to be movable with respect to the hole 80, for example. You may make it adjustable by doing this.

As shown in FIG. 8, the airflow suppression members 52 or 54 are formed by a single member, and the airflow suppression members 52 or 54 above or below the inclined movement direction are provided with a length dimension and a gap 62 or a hole 80. The width dimension may be formed into a shape that is different depending on the location in the weft direction. In addition, the airflow control member 52 or 54 may be integrally provided with the clasp 34 or 36 or the body holding member 38.

The present invention is not limited to the above embodiments, and various modifications can be made without departing from the spirit thereof.
