Description

DETAILED DESCRIPTION OF THE INVENTION Object of the Invention (Field of Industrial Application) The present invention relates to a weft processing method in a shuttleless loom such as a fluid jet loom, a rapier loom, or a gripper loom.

(Prior technology) In general, the incidence of weft insertion errors in shuttleless looms aiming for higher speeds, especially fluid jet looms, is higher than in shuttled looms, but the loom is stopped to handle the weft insertion errors. This goes against the goal of increasing productivity, which is the reason for the high-speed design of looms. However, once a weft insertion error occurs, the machine must be stopped and the weft insertion error must be dealt with in order to maintain the quality of the woven fabric. The loom is stopped based on the weft insertion error detection signal from the weft detection device, but in order to prevent damage to various parts of the high-speed loom, the loom is stopped after the loom has inertia operated for one rotation or more, so weft insertion is not possible. Mistaken weft threads (hereinafter referred to as "mistake threads") are beaten before the machine stops and are woven into the woven fabric. Therefore, it is necessary to reverse the machine to release the warp from holding the misplaced thread and remove the misplaced thread, but conventionally, this misplaced thread removal work has been done manually. However, since the mis-threads are inserted into the fabric like normal weft threads,
Even if the warp threads are brought to the maximum open state, the state in which the misplaced threads are held by the warp threads is not sufficiently released. Therefore, removing the misplaced threads becomes very complicated, and the loom stops for a long time, which impedes productivity improvement.

An example of a weft processing device that attempts to solve these problems is disclosed in Japanese Patent Laid-Open No. 58-220856.

This weft processing device is movably supported by a guide rail installed in the weaving width direction, and the weft separation fingers of the processing device are moved from outside the warp shedding into the warp shedding at an appropriate position within the weaving width. Mistaken yarns are separated from the woven fabric and delivered to a weft gripping mechanism inserted into the warp opening. The gripping mechanism is moved from inside the warp opening to outside the warp opening, and a part of the missed thread is pulled out outside the warp opening, and the remaining missed thread is pulled upward from inside the warp opening by a weft pulling mechanism consisting of a pair of rollers. It is about to be removed.

(Problems to be Solved by the Invention) However, in this method for handling misplaced yarns using the conventional device, some of the misplaced yarns may reach the suction pipe disposed on the opposite side of the weft inserting side of the fabric due to fragmentation. In the case where the weft yarn is separated from the woven fabric by the weft separating finger, the same misplaced yarn is removed from the woven fabric by suction pipe from inside the warp opening.
A method of removing the mis-shredded yarn using only suction force from inside the warp opening, where it easily comes into contact with the warp, lacks reliability. In addition, as for the misplaced yarn remaining in the woven fabric, it is separated near the end on the weft insertion side and pulled out from the warp opening at that position, so only the misplaced yarn near the take-out position is removed. Since it is loosened and other parts are not loosened sufficiently, it is difficult to pull out the entire misplaced thread outside the warp opening, and there is a problem that the misplaced thread may break. Further, a pair of mis-yarn gripping members forming a weft-yarn grasping mechanism for grasping mis-yarn separated from the woven fabric are both inserted into the warp opening, but such members other than the weft separation fingers are Inserting the warp threads into the opening or pulling them out from the opening increases the rate of damage to the warp threads, which is undesirable as it may cause warp thread breakage.

Further, the fingers reciprocate in a substantially elliptical orbit, and the erroneous threads separated from the woven fabric by the fingers are transferred between the pair of erroneous thread gripping members in the warp opening where there is limited space. , It is difficult to set the gripping timing for the same thread.

Structure of the Invention (Means for Solving the Problems) In order to solve the above-mentioned problems, in the present invention, in a loom that is stopped based on a loom stop signal, the warp threads are formed in an open state and the loom is stopped immediately before the loom stops. The woven state of the weft threads woven into the woven fabric is released, and the weft thread processing device, which is normally retracted to one of both ends of the fabric, is moved in the weave width direction and stopped at a predetermined position within the weave width. At the same stop position, the weft separating member of the weft processing device enters the warp opening from outside the warp opening to separate the weft from the woven fabric, and this weft separation operation is performed at multiple positions within the woven width, and the final weft In the separating operation position, the weft separating member is moved from inside the warp opening to outside the warp opening, a part of the separated weft is pulled out from inside the warp opening to outside the warp opening, and the remaining weft inside the warp opening is removed by the weft pulling means. The warp threads are removed by pulling them out of the warp opening.

(Function) In other words, when a weft insertion error occurs and the erroneous thread is woven into the woven fabric, an open state is created for the warp threads and the woven state of the erroneous thread woven into the woven fabric is released. In this step, the weft processing device, which is in the retracted position on one of the cloth ends, is moved into the weaving width, and the weft separation member is moved from the woven cloth side toward the reed side, and enters into the warp shedding from outside the warp shedding. On this occasion,
A weft separation member sweeps the fabric front, and the missed yarn is separated from the woven fabric by the separation member. This separation operation is performed at a plurality of positions within the weaving width to separate most of the misplaced yarns from the woven fabric. Then, the final weft separation operation is performed at the center of the weaving width, and at this position, the weft separation member is moved from inside the warp opening to outside the warp opening while engaging and holding the separated missed yarn, and a part of the missed yarn is removed. Pull it out of the warp opening. Then, a part of the missed yarn pulled out of the warp shedding is gripped by a weft gripping mechanism provided in the weft processing device, and from this state, the weft processing device is caused to travel toward the retracted position. As a result, all the misplaced yarns within the warp shedding are pulled out to the outside of the warp shedding and removed.
Therefore, when such weft processing is performed, the only member inserted into the warp opening is the weft separation member, so that the chance of warp threads being damaged is extremely reduced. In addition, since the missed yarn separated from the woven fabric is pulled out outside the warp shedding and is held outside the warp opening, it is easier to transfer the missed yarn compared to a method in which the missed yarn is held inside the warp shedding where space is limited. And the timing of gripping can be set very easily. Therefore, removal of misplaced threads is reliably performed.

(Example) Hereinafter, an example in which the present invention is embodied in a fluid jet loom will be described based on the drawings.

Reference numeral 1 denotes a main nozzle attached to one end of the slay 2, and the weft yarns Y guided to the main nozzle 1 via a length measuring mechanism and storage mechanism (not shown) are weft yarns arranged in parallel on the slay 2. The weft is injected from the main nozzle 1 into the weft guide path S formed by the guide member 3. The weft Y inserted into the weft guide path S is passed through a plurality of auxiliary nozzles 4 arranged at predetermined intervals along a large number of weft guide members 3.
The flight is assisted by the auxiliary jet fluid from the.

A predetermined number of weft guide members 3 and auxiliary nozzles 4 are attached to a plurality of blocks 5 (six in the illustrated example), and the auxiliary nozzles 4 of each block 5 connect fluid passages 5a provided inside them. It is connected to a fluid supply source (not shown) through the fluid supply source. Then, in synchronization with the flight timing of the weft yarn Y ejected from the main nozzle 1, the auxiliary nozzle 4 on the side of the nozzle 1 sequentially injects it toward the anti-weft insertion side in units of 5 blocks, and the tip of the weft yarn Y is It is designed to be pulled sequentially from the main nozzle 1 side to the anti-main nozzle side in a relay manner.

When the weft yarn Y ejected from the main nozzle 1 is inserted normally and reaches the end of the woven fabric W on the side opposite to the main nozzle, the weft yarn 2 moves along the arrow P in FIG.
While moving forward in the direction, the guide hole 3 of the weft guide member 3
The weft yarn escapes from a through the slit 3b, and the same weft yarn is driven into the front W1 of the woven fabric W by the reed 6 on the slay 2 and woven into the woven fabric W, and the fabric end of the woven fabric W on the main nozzle side It is cut by a cutter (not shown) provided nearby. Then, the subsequent weaving operation is continued. If a weft insertion error occurs in which the weft yarn Y does not reach the fabric edge on the side opposite to the main nozzle, a weft detection device (not shown) provided on the weft guide member 3 located near the fabric edge will be detected. )
detects a weft insertion error, and the machine is stopped based on a weft insertion error detection signal from the detection device. The weft detection device is composed of light emitting and receiving elements arranged opposite to each other across the slit 3b of the weft guide member 3, and emits a weft insertion error detection signal when the weft does not pass through the slit 3b during beating. .

After the weft insertion error detection signal (also a machine stop signal) is issued, the machine rotates approximately one and a half times due to inertia and then stops. That is, when a weft insertion error occurs, the weft insertion error detection signal is issued while the reed 6 moves forward in the direction of arrow P from the most retracted position shown by the solid line in FIG. After the reed is struck, the reed 6 once returns to the most retracted position, moves forward again, and stops just before the reed is struck. At this time, the miss thread Y1 is woven as shown in FIG. During this inertia operation, the error thread Y1
Subsequent weft insertion is performed and the weft is ejected from the main nozzle 1, but the ejected weft is prevented from being inserted by a weft insertion prevention mechanism (not shown) provided near the main nozzle 1. ing.

At this retracted position A, a planar wedge-shaped engagement projection 11A is fixed to the front surface of the guide rail 9, and another engagement projection 11B is fixed to the front surface of the other end of the guide rail 9. A suction pipe 12 is provided inside one of the support frames 7 and extends below the weft processing device 10.

As shown in FIGS. 2 and 3, the weft processing device 10 is suspended and supported by a guide roller 14 and a drive roller 15 provided inside the upper wall of the frame 13 so as to be able to run on a guide rail 9. A plurality of guide rollers 1 provided in

7a is meshed with a bevel gear 18 fixed to one end of the shaft 15a of the drive roller 15. Therefore,
By rotating the drive motor 17 in the forward and reverse directions, the weft processing device 10 is moved left and right along the guide rail 9.

Front side of guide rail 9 (right side in Figure 3)
A shaft 20 is rotatably supported by a support bracket 19 attached and suspended from the inside of the upper wall of the frame 13. In FIG. A timing pulley 22 is fixedly attached. A drive motor 23 capable of forward and reverse rotation is provided near the gear 21 on the inside of the side wall of the frame 13, and its drive gear 23a is meshed with the gear 21.

An arm 24 is rotatably suspended from a shaft 20 between both support pieces 19a of the support bracket 19, and a shaft 25 is rotatably supported at its lower end. The rotation range of the arm 24 is restricted by a pair of restriction rods 44 and 45 protruding from the right side wall of the frame 13. In FIG. 2, a timing pulley 26 is fixed to the left end of the shaft 25, and a timing belt 27 is hung between the pulley 26 and the timing pulley 22. A weft separation arm 28 is fixed to the inside of the timing pulley 26 between the timing pulley 26 and the arm 24, and a brake lining 29 is fixed to the side surface of the arm 28 on the timing pulley 26 side. , axis 25
It is possible to rotate relative to the And axis 25
The arm 24 and the brake lining 29 are pressed against each other by a spring 31 interposed between the arm 24 and a nut 30 screwed onto the right end of the brake lining. A weft separation member 33 is attached to the tip of the weft separation arm 28 via a leaf spring 32. A limit switch 34 for stopping the drive motor 23 is provided on the side surface of the arm 24 in the vicinity of the base end of the weft separation arm 28, and a control piece 28a protruding from the base end of the weft separation arm 28 normally operates the limit switch 34. It is designed so that it comes into contact with the ON state. Further, a limit switch 35 for reversing the drive motor 23 is provided on the side surface of the base end of the arm 24.

Furthermore, both support pieces 19a of the support bracket 19
A pair of limit switches 46 and 47 are provided between them, and are turned on and off by a control piece 24a protruding from the base end of the arm 24 in the opposite direction.

A weft grip lever 37 is rotatably supported on a support shaft 36 protruding from the left side wall of the frame 13 in the vicinity of the guide rail 9, and a tension spring 38 is interposed between the upper end of the weft grip lever 37 and the frame 13.
Therefore, in FIG. 3, it is always urged to rotate counterclockwise. A gripping portion 37a is formed at the lower end of the weft gripping lever 37, and the frame 1
It can come into contact with a receiving part 39 formed at the lower end of the left side wall of No. 3. Note that 13a on the right side wall of the frame 13 is a hole through which the wedge-shaped engagement protrusion 11A passes when the weft processing device 10 is in and out of the retracted position A, and when the weft processing device 10 is in the retracted position A, the gripping portion 37a and receiving part 39
The weft gripping lever 37 is rotated by the engaging protrusion 11A in the direction in which the weft gripping lever 37 is moved away from the weft gripping lever 37. Similarly, a hole (not shown) for passing another engagement protrusion 11B is formed in the left side wall of the frame 13. That is, when the weft processing device 10 moves toward the main nozzle and the engaging protrusion 11B passes through the hole (not shown), the weft grip lever 37 is rotated against the tension spring 38, and the A limit switch 48 for reversing the drive motor 17 provided in the drive motor 17 is turned on.
Also, a shaft 40 protruding from the right side wall of the frame 13
A latch lever 41 is rotatably supported while being inserted between the arm 24 and the timing belt 27, and its latch portion 41a can be hooked to the upper end of the weft gripping lever 37. At the same time, a hanging piece 4 hanging from the center of the lever 41
The lower end of 1b can come into contact with the weft separation arm 28. Further, the upper edge of the locking lever 41 comes into contact with the limit switch 35 so that it can be turned on.

A pair of proximity switches 42 and 43 are vertically disposed on the right side wall of the frame 13 in close proximity to the guide rail 9. The upper proximity switch 42 corresponds to the magnets M1, M2, M3, and M4 fixed to the front surface of the guide rail 9 as shown in FIG. 1, and the proximity switch 43 corresponds to the magnet M. When the proximity switches 42 and 43 are activated, the drive motor 17 is stopped and the drive motor 2
3 is now driven.

In this embodiment, the proximity switch 42 is activated only when the weft processing device 10 is running leftward along the guide rail 9, that is, when the drive motor 17 is rotating forward, and the weft processing device 10 is moving rightward. The proximity switch 43 is operated only when the vehicle is traveling, that is, when the drive motor 17 is rotating in reverse.

Further, when the proximity switch 43 is operated, both limit switches 46 and 47 are put in an inoperative state, and the drive motor 23 is controlled by both switches 46 and 47.
is becoming unstoppable.

In this embodiment, when a weft insertion error occurs, the error thread processing is automatically performed based on the error thread processing program. Therefore, the operation of mis-thread processing when a weft-insertion error occurs will be explained next.

When a weft insertion error occurs, as described above, the erroneous yarn Y1 is woven as shown in FIG. Weft insertion of the ejected weft yarn is prevented.

After the loom has stopped, the loom is automatically reversed about one and a half times, and the reed 6 is stopped at the most retracted position shown by the solid line in FIG. As the machine reverses, the warp threads T1 and T2 move in the directions of the arrows in FIG. 4, and when the machine stops reversing, they reach the maximum opening state shown in FIG. 5. Therefore, the gripping state of the misplaced thread Y1 by the warp threads T1 and T2, that is, the weaving state is released.

After the machine is reversed, the drive motor 17 is driven in forward rotation,
The weft processing device 10 in the state shown in FIG.
It runs toward the main nozzle 1 side from the retreat position A shown in FIG. When the proximity switch 42 faces the magnet M1, the driving of the drive motor 17 is stopped, and the weft processing device 10 stops running at the position shown by the chain line in FIG. At the same time as the weft processing device 10 stops, the drive motor 23 is rotated forward. Along with this, the shaft 20 is rotated in the direction of arrow Q in FIG. 3, and this rotation causes the timing belt 27 to rotate.
is transmitted to the shaft 25 through the shaft 20, and the shaft 25 is rotated in the same direction as the shaft 20. In this case, since the weft separation arm 28 fixed to the timing pulley 26 is pressed against the arm 24 via the brake lining 29, frictional torque exists between the arm 24 and the weft separation arm 28, and both There is no relative rotation between them. Therefore, the arm 24 and the weft separation arm 28 rotate in a clockwise direction about the shaft 20 from the state shown in FIG. 3 as a unit. As the arm 24 and the weft separation arm 28 rotate, the tip of the weft separation member 33 slides on the woven fabric W and moves toward the woven fabric W1 side. Then, as shown in FIG. 6, when the tip of the weft separating member 33 reaches the woven fabric W1, the tip of the weft separating member 33 engages with the missed yarn Y1, and the missed yarn near the stopped weft yarn processing device 10. is separated from the woven fabric W by a weft separating member 33 that enters into the warp opening from outside the warp opening. In this case, since there is a temple device (not shown) just above the fabric edge near the woven fabric, the separating operation of the weft separation member 33 is performed somewhat inside the fabric edge, and a small portion of the tip of the miss thread Y1 is removed. In some cases, it is not separated from the fabric. When the arm 24 further rotates, the miss yarn Y1 is engaged and held by the weft separation member 33 and is separated from the fabric as shown in FIG. 8, and the arm 24 is moved to the regulating rod as shown in FIG. 45 and at the same time the control piece 24a
As a result, the limit switch 46 is turned on, the drive motor 23 is reversely rotated, the arm 24 returns to the state shown in FIG. 3, and its rotation is restricted by the restriction rod 44. At the same time, the limit switch 47 is turned on by the control piece 24a, the drive motor 23 is stopped, and the drive motor 17 is rotated forward.
The weft processing device 10 runs on the guide rail 19 toward the main nozzle, and performs the weft separation operation again at the positions of the magnets M2 to M4.

Thereafter, the weft processing device 10 reaches the position of the engaging protrusion 11B on the main nozzle 1 side, as shown in FIG.
8 is turned on, the drive motor 17 is reversed, and the weft processing device 10 moves toward the retracted position A side. When the magnet M and the proximity switch 43 face each other, the drive motor 17 is stopped and the weft processing device 10 is stopped at the position shown in FIG. The weft separation operation shown in the figure is performed. At this time, since the limit switch 46 is in an inactive state, the drive motor 23 is not stopped by the limit switch 46. Therefore, as shown in FIG. 7, the arm 24 comes into contact with the regulating rod 45, and the rotation of the arm 24 is prevented, but the rotational force of the shaft 25 by the drive motor 23 is transferred between the arm 24 and the weft separation arm 28. The shaft 25 rotates relative to the arm 24 by overcoming the frictional torque. As a result, the weft separation member 33
is rotated from the position shown by the solid line in FIG. 7 to the position shown by the chain line, and a part of the missed yarn Y1 held by the separating member 33 is pulled out to the outside of the warp shedding.
As shown in FIG. 9, the weft separation member 33 is disposed on the side of the gripping part 37a and the receiving part 39, which are in a separated state. At the same time, the weft separating arm 28 comes into contact with the hanging piece 41b of the latch lever 41, the latch lever 41 is pushed upward, and the latch part 41a is disengaged from the upper end of the weft gripping lever 37. Therefore, the weft gripping lever 41 is rotated counterclockwise around the support shaft 36, the gripping part 37a and the receiving part 39 are joined, and a part of the missed yarn Y1 pulled out of the warp opening is removed. It is held between the two. Further, by pushing up the latch lever 41, the limit switch 35 is turned on, and the drive motor 23 is rotated in the reverse direction.

As the drive motor 23 reverses, the weft separation arm 28 and the arm 24 are integrally rotated counterclockwise about the shaft 20. In this case, the hanging piece 41b of the latch lever 41 and the weft separation arm 2
Even if the engagement with the weft gripping lever 8 is released, the hook portion 41a is in contact with the tip of the weft gripping lever 37, and there is no fear that the weft gripping lever 37 will fall.
When the arm 24 comes into contact with the regulating rod 44 and the rotation of the arm 24 is prevented, the weft separation arm 28
is rotated counterclockwise relative to the arm 24 about a shaft 25. Then, the control piece 28a turns on the limit switch 34, thereby stopping the drive motor 23, the drive motor 17 is reversed, and the weft processing device 10 runs along the guide rail 9 in the direction of the retracted position A. . In this case, since the missed yarn Y1 is held by the processing device 10 at the center of the weaving width, the weft processing device 1
As the thread 0 moves toward the retracted position A, the miss yarn Y1 is pulled out from inside the warp opening to outside the warp opening,
When the weft processing device 10 reaches the retracted position A, most of the missed yarn Y1 is pulled out to the outside of the warp shedding. When the weft processing device 10 reaches the retracted position A, the gripping portion 37a of the weft gripping lever 37 and the receiving portion 39 are disengaged from each other due to the action of the engaging protrusion 11A, and the erroneous yarn Y1 is released, and the suction pipe 12 is activated, and this released miss thread Y
1 is removed by suction through the same pipe 12.

When the weft processing device 10 returns to the retracted position A and the erroneous yarn Y1 is suctioned and removed, the loom is automatically reversed by a predetermined amount and stopped at the rotation position most suitable for restarting, and the loom operation is resumed. It will be restarted.

As described above, in this embodiment, during normal operation of the loom, the weft processing device 10, which is at the retracted position A, is caused to reciprocate on the guide rail 9 when a weft insertion error occurs, and during this movement, the weft thread processing device 10 is moved back and forth on the guide rail 9 at a plurality of predetermined positions. The processing device 10 is stopped, the processing device 10 is operated to separate the misplaced yarn Y1 from the woven fabric W, and at the final stop position, a part of the misplaced yarn Y1 is pulled out from inside the warp opening to outside the warp opening and grasped. Since the yarn is returned to the retracted position A in this state, the trouble associated with the conventional work of manually separating the erroneous yarn from the woven fabric is eliminated, and the erroneous yarn can be automatically disposed of. Therefore, the weft processing method of this embodiment can cope with the recent trend towards automation of weaving machines. Further, it is possible to shorten the stop time of a high-speed loom for the purpose of improving productivity, and it is possible to cope with the trend toward higher speeds of looms.

Furthermore, since the weft separating member 33 is the only member that separates the warp threads and enters the warp thread opening from outside the warp opening, the rate of damage to the warp threads is significantly reduced compared to the weft processing method described in the prior art.
Furthermore, the weft gripping mechanism (the weft gripping lever 37 and the receiving part 39) is set and arranged outside the warp opening, and the misplaced yarn is delivered from the weft separation member 33 outside the warp opening. Compared to a method in which the weft is transferred from the weft separation member and held, there is more space for installing the weft gripping member, and the timing of weft transfer can be easily set.

The present invention is not limited to the above embodiments,
For example, as shown in FIG. 16, a drive motor 49 having a drive roller 49a is provided in place of the receiving portion 39 in the embodiment, a driven roller 50 is provided at the lower end of the weft gripping lever 37, and further, By arranging a suction pipe 51 directly above the joining position of both rollers 49a, 50, a part of the missed yarn pulled out of the warp opening is removed from both rollers 49a, 50.
50, the drive motor 49 may be driven to pull out the remaining misplaced threads in the warp opening, and the suction pipe 51 may be used to suction and remove them.

In addition, although the present invention was embodied in the process of mis-thread processing in the above-mentioned embodiments, it is not limited to mis-thread processing, but can also be applied to weaving during inertial operation when the machine is stopped due to warp cutting during weaving, or when the machine is artificially stopped. It is also possible to implement the present invention in the case where the weft yarns that have been removed are removed in order to prevent the formation of weaving steps.

Effects of the Invention As detailed above, the weft processing method of the present invention separates misplaced threads from the woven fabric and removes them from inside the warp opening without performing complicated manual work and without damaging the warp threads. This provides an excellent effect in that the removal process can be performed reliably outside the warp shedding.
