BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wire heald separating method and a wire heald separating apparatus, and a wire heald used for separating a wire heald located at a front end from a heald group composed of a large number of wire healds arranged in a horizontal direction. The present invention relates to a separation method and a wire-held separation device.

2. Description of the Related Art Japanese Patent Application Laid-Open No. 6-57596 is an example of a conventional heald separation apparatus. The heald separation device disclosed in this publication inserts a separation claw between the frontmost heald and the next heald in a group of healds suspended via vertically extending upper and lower guide rails, The foremost heald is separated so as to be slightly separated from the other healds. By appropriately performing such separation, the work of drawing out the heald, which is performed while suctioning the center of the heald with the nozzle block, can be efficiently achieved.

[0003]

However, the above-described technique is a heald separation device used for flat healds, and is not a wire heald separation device. That is, the flat heald A is made of SUS420 having spring properties.
As shown in FIG. 20, it has a flat elongated rod portion 1 having a rectangular cross section, a mail 2 is formed at the center of the rod portion 1, and ring portions are provided at both ends of the rod portion 1. 3 are provided, and each ring portion 3 is formed with a guide hole 4 having a long hole shape. The flat heald A easily bends in the direction of the arrow, but has a characteristic that it is strong against twisting and is hardly deformed. Even when the heald group is suspended by the guide rail, the flat heald A is always regularly aligned without being entangled. Therefore, even if the separation claw is inserted between the healds, the healds can be appropriately separated in order from the front end of the heald group.

On the other hand, the wire heald B is made of hard steel wire (60 carbon), has an elongated rod portion 5 as shown in FIG. 21, and a mail 6 is formed in the center of the rod portion 5. Ring portions 7 are provided at both ends of the rod portion 5, and a guide hole 8 having a long hole shape is formed in each ring portion 7. The wire heald B has such characteristics as being extremely lightweight, easy to handle, and inexpensive. However, the wire heald B has a disadvantage that it is extremely pliable, easily entangled with each other due to the pliability, and easily deformed.

Therefore, when the flat-held separating device disclosed in the above-mentioned Japanese Patent Laid-Open No. 6-57596 is applied to the wire heald B, the wire heald B is suspended on the guide rail 9 as shown in FIG. The wire heald B is not aligned regularly like the flat heald group because the wire heald B suffers from its flexibility and is entangled with each other. Therefore, when the wire heald group is sequentially separated from the front end, even if the separation claw is simply inserted between the wire healds B, the wire heald group is not necessarily separated from the end in order, and the wire healds B are entangled with each other and the front and back are reversed. There is a possibility that the heald will be separated in the state where it has become empty.

Further, Japanese Patent Laid-Open No. 64-77653 also discloses a heald separating device, and this heald separating device inserts a separating protrusion into a predetermined position of a wire heald group to create a plurality of wire heald bundles. . However, even in such a heald separating device, there is a possibility that the entanglement of the wire healds B may damage and the wires may not be properly separated.

Further, the heald separation device disclosed in Japanese Utility Model Publication No. 4-49189 is a technique for wire healds, but the separation claw is engaged with the rod portion of the most advanced wire heald, and the most advanced heald separation device is used. Since the wire heald is separated, there is a possibility that the wire heald cannot be properly separated as described above.

The present invention has been made to solve the above problems, and in particular, provides a wire heald separating device and a wire heald separating method for surely separating the frontmost wire heald from the group of wire healds. The purpose is to

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of a wire-held separating apparatus and a wire-held separating method according to the present invention will be described below in detail with reference to the drawings.

FIG. 1 is a perspective view showing a wire-held separating device according to the present invention. The wire-held separating device 10 shown in the figure includes a large number of wire-helds B (hereinafter also referred to as “held group”) suspended from a horizontally extending guide rail 9 as shown in FIG. The frontmost wire healds B can be separated one by one, and in this case, the heald group is always urged forward by compressed air, a rotating brush, or the like (not shown). The wire-held separating device 10 includes a heald-drawing member 11 that is arranged in front of the upper ring portion 7 of the front-most wire-held B so as to face it.

As shown in FIG. 1, the heald extraction member 11 has a pair of left and right magnetic heads 12 branched so as to sandwich the upper guide rail 9. The magnetic head 12 is made of an iron core and has a guide rail insertion portion 12c extending in the vertical direction at the center. A ring seating recess 13 for securely seating the upper ring portion 7 is formed at the lower end of the magnetic head 12, and an exciting coil portion 14 is arranged at the upper end of the magnetic head 12. As shown in FIGS. 2 to 4, the ring seating recess 13 is
The ring portion 7 is cut out to have substantially the same shape as the ring portion 7 and is arranged so as to sandwich the upper guide rail 9 inserted into the guide rail insertion portion 12c. And the upper guide rail 9
Is inserted into the guide rail insertion portion 12c through a gap δ that does not allow the ring portion 7 to be sandwiched.

Further, at the lower end of the magnetic head 12, there is formed a claw-shaped hooking portion 12a which projects inward, and the lower end of the ring seating recess 13 is narrowed inward by this hooking portion 12a. The wire heald B can be suspended at this portion. Therefore, when the magnetic head 12 is brought close to the frontmost ring portion 7, this ring portion 7 is magnetically attracted to the ring seating recess 13 and the ring seating recess 13
The upper ring portion 7 can be reliably accommodated inside. In addition, since the ring portion 7 can be suspended from the neck by the hook portion 12a, it is possible to appropriately prevent the ring portion 7 from sliding down from the ring seating concave portion 13 due to vibration or the like.

As shown in FIG. 1, the heald pull-out member 11 is moved in a predetermined direction by the driving means 15 constituted by a combination of air cylinders. The drive means 15 is composed of a combination of an air cylinder 15a for horizontal driving fixed to the frame F and air cylinders 15b, 15c for vertical driving. By using these air cylinders 15a to 15c. The heald extraction member 11 can be moved up and down in the vertical direction, and at the same time, moved back and forth along the guide rail 9 in the front-back direction.

As shown in FIGS. 1 and 2, in the front end portion of the heald group suspended on the guide rail 9, between the upper guide rail 9 and the lower guide rail 9,
A pair of upper and lower heald guide portions 16 and 17 are arranged, and the upper heald guide portion 16 is a flat plate extending horizontally along the guide rail 9. A slit-shaped rod guide rail 18 extending linearly along the upper guide rail 9 is formed in the heald guide portion 16, and the rod guide rail 18 is located directly below the upper guide rail 9. There is.

The lower heald guide portion 17 is a flat plate extending horizontally along the guide rail 9.
The heald guide portion 17 has a slit-shaped rod portion guide rail 19 that linearly extends along the lower guide rail 9.
Is formed, and the rod portion guide rail 19 is located directly above the lower guide rail 9. Therefore, since the upper and lower portions of the rod portion 5 can be guided and slid along the rod portion guide rails 18 and 19, the upper and lower portions of the wire heald B are sandwiched between the rod portion guide rails 18 and 19, and the wire heald B is fixed. It can be sent reliably.

Further, between the upper heald guide portion 16 and the magnetic head 12, a pair of push-back claws 20 as a heald pusher are provided on the left and right, and each push-back claw 20 is parallel to the heald guide portion 16. While extending, it is formed in an L shape and has a claw portion 20a at its tip. Each claw portion 20a is
It faces the upper ring portion 7 of the frontmost wire heald B and is located in front of the magnetic head 12. Claw part 2
A slit 21 for passing the rod portion is formed between 0a, and this slit 21 is located directly above the rod guide rail 18 and is formed slightly larger than the rod portion 5 to prevent passage of the rod portion 5. It is possible.

The push-back claw 20 is moved back and forth in the horizontal direction by the driving means 24 composed of an air cylinder fixed to the frame F. Therefore, by moving the push-back pawl 20 toward the heald group and passing the rod portion 5 through the slit 21, the pawl portion 20a does not collide with the frontmost rod portion 5 and only the next ring portion 7 is provided. It is possible to cause a collision, and the claw portion 20a can reliably push the next ring portion 7.

Above the upper guide rail 9, a plate-shaped heald lift stopper 22 extending near the magnetic head 12 is provided.
Is arranged. As shown in FIG. 3, the front end 22a of the heald lift stopper 22 is located in the immediate vicinity of the ring seating recess 13 and extends linearly in parallel to the surface of the magnetic head 12. That is, the heald lifting stopper 22 is extremely close to the magnetic head 12, and extends horizontally along the upper guide rail 9 as shown in FIG. 2 and is arranged immediately above the upper guide rail 9. ing.

Therefore, even when the magnetic head 12 is lifted while the two ring portions 7 are magnetically attracted to the magnetic head 12, the rings other than the frontmost ring portion 7 housed in the ring seating recess 13 are accommodated. Part 7 is a heald lift stopper 22
And the extra ring portion 7 is not taken out. In this way, the heald lift stopper 22
Achieves a function like a scraped-off plate to prevent the next ring portion 7A from being pulled out. In addition, by making the depth of the ring seating concave portion 13 slightly larger than the thickness of the ring portion 7 in the extending direction of the upper guide rail 9,
The heald rise stopper 22 is provided on the side surface 12b of the magnetic head 12.
(See FIG. 4), the ring seat recess 13
The ring portion 7 housed inside the heald lifting stopper 22
The magnetic head 12 can be moved up without fail.

As shown in FIG. 1, the wire-held separating device 10 described above includes a block-shaped push-back member 30 as a heald pusher for separating the lower ring portion 7 of the frontmost wire heald B. The push-back member 30 faces the lower ring portion 7 at the front end and is arranged below the lower guide rail 9. Then, the push-back member 30 is moved back and forth in the horizontal direction by the driving means 31 composed of an air cylinder fixed to the frame F. Therefore, after pulling up the wire heald B at the foremost end and shifting the ring portion 7 of the wire heald B at the foremost end with respect to the ring portion 7A of the next wire heald B, the exposed lower ring portion 7A for the next wire is held. Push back member 30
The horizontal lower part of the push-back member 30 can push back the next lower ring portion 7A.

Further, the wire-held separating mechanism 10 is provided with a guide rail steady rest means 60 for preventing the upper guide rail 9 from swinging due to vibration or the like. The steady rest 60 includes a pair of left and right arms 61 that sandwich the upper guide rail 9 from both sides, a claw-shaped chuck portion 62 provided at the tip of each arm 61, and each arm 6.
And a drive unit 63 including an air cylinder mechanism for driving 1 to the side, and is configured as an air chuck. When the upper guide rail 9 is vibrating due to vibration or the like, the steadying means 60 is used by sandwiching the upper guide rail 9 from the side by the chuck portion 62.

Particularly, when the magnetic head 12 is lowered from the upper side toward the upper guide rail 9, it is effective in surely inserting the upper guide rail 9 into the guide rail insertion portion 12c of the magnetic head 12. Further, it is also effective in preventing the guide rail 9 from colliding with the magnetic head 12 when the upper guide rail 9 is inserted into the guide rail insertion portion 12c.

Next, the operation of the wire-held separation device 10 will be described based on the above-mentioned configuration.

First, as shown in FIG. 5, the magnetic head 12
Position the heald withdrawal member 11 in a location such that has a slight clearance with the heald lift stopper 22. After that, by pressing the heald group in the direction of arrow P with compressed air or the like, the ring seat recess 13 of the magnetic head 12 is pressed.
Press the frontmost ring portion 7 against. Then, by supplying a magnetic attraction DC current to the coil portion 14, the ring seating recess 13 is magnetically attracted to the frontmost ring portion 7. Thereafter, as shown in FIG. 6, the heald extraction member 11 is raised in the direction of the arrow U by using the air cylinder 15b, so that the ring portion 7 at the foremost end is guided to the upper guide rail 9a.
Rises while being inserted into. Then, as shown in FIG. 2, the next ring portion 7A is exposed. At this time, even if the next-order ring portion 7A is lifted up, the second-order ring portion 7A is not moved up by being blocked by the heald lifting stopper 22.

When pulling up the wire heald B at the foremost end, even if the mails 6 are intertwined with each other as shown in FIG. 7, by pulling up the wire heald B at the foremost end, as shown in FIG. 6 and the rod part 5 become entangled. Since the mail 6 is not easily elastically deformed, the entanglement between the mails 6 is difficult to eliminate, while the rod portion 5 is easily elastically deformed, so that the entanglement between the mail 6 and the rod portion 5 is separated from each other. It is resolved with a little force.

As shown in FIG. 9, after the wire head B at the foremost end is pulled up by the magnetic head 12 and the ring portion 7 of the foremost wire heald B is displaced with respect to the ring portion 7A of the next wire heald B. , Air cylinder 2
4 is driven. As a result, the push-back claw 20 moves in the horizontal direction toward the exposed next upper ring portion 7A, and while the push-back claw 20 is moving, the rod portion 5 of the wire-held B at the front end is moved to the claw portion 20a. While passing through the slit 21 between, the claw portion 20a presses the next upper ring portion 7A and pushes the next ring portion 7A back along the guide rails 9, whereby the uppermost ring portion at the front end is pressed. Separate 7 and the remaining heald group.

Further, using the air cylinder 31, the push-back member 30 is moved toward the exposed next lower ring portion 7A. As a result, after the ring portion 7A of the frontmost wire heald B is displaced with respect to the ring portion 7A of the next wire heald B, the exposed lower ring portion 7A of the next lower layer is moved to the tip of the push-back member 30. By pushing back with, the ring portion 7A on the lower side of the front end can be separated from the heald group. In this state, whether or not the frontmost wire heald B has been reliably separated is detected by the band-shaped laser light.

For example, the rod portion 5 of the wire heald B at the foremost end
At the upper portion (reference numeral 71), a lower portion (reference numeral 72) of the rod portion 5 of the frontmost wire heald B, and a lower position (reference numeral 7) of the lower ring portion 7 of the frontmost wire heald B.
3), the frontmost wire-held B and the next wire-held B
It is suitable to irradiate the position (reference numeral 74) between and with the band-shaped laser light. This band-shaped laser light extends in a direction perpendicular to the paper surface of FIG. 9 and is used in combination with a detection unit (not shown) for detecting an abnormality by being blocked. Therefore, at positions 71 and 72, it is detected whether or not the frontmost wire heald B is separated, and at position 74, it is detected whether or not the wire healds B are entangled with each other, and at the position 73. , It is detected whether or not the frontmost wire heald B is pulled up at the time of separation. Note that FIG.
The entanglement between the wire healds B as shown in (4) is often eliminated by blowing compressed air to the portion of the mail 6.

Thereafter, as shown in FIG. 10, the magnetic head 12 is retracted in the direction of arrow V while the frontmost ring portion 7 is attracted to the magnetic head 12. During this retreat, in a region Q between the push-back claw 20 and a ring abutment bar 23, which will be described later, the current flowing through the coil portion 14 is switched to the demagnetizing AC attenuation current, and the ring seating recess 13 and the ring portion 7 are separated. The residual magnetism generated in the ring portion 7 is completely removed while weakening the magnetic coupling force. As a result, the ring portion 7 at the front end is
Due to the vibration transmitted from the respective drive sources of the threading device (not shown) to the magnetic head 12, the ring seat recess 13 is detached,
Due to its own weight, it falls on the upper guide rail 9 in the area Q. In this way, by retracting the magnetic head 12 by a predetermined distance, as shown in FIG. 8, the mail 6 and the rod portion 5 are
Even when and are intertwined with each other, the wire heald B is pulled so as to be separated from each other, the entanglement between the mail 6 and the rod portion 5 is easily canceled, and the wire heald B at the foremost end is removed.
Separation is achieved.

A ring abutment bar 23 is arranged on the retracted side of the magnetic head 12, and the ring abutment bar 23 is opposed to the ring seating recess 13. In this case, since the tip of the ring abutment bar 23 can abut against the ring portion 7 in the ring seating recess 13 while the magnetic head 12 is retracting, the ring portion 7 can be forcibly separated from the magnetic head 12. Therefore, the ring portion 7 can be surely dropped in the area Q.

Then, the push-back claw 20 is retracted by the air cylinder 24 and the push-back member 30 is retracted by the air cylinder 30, thereby releasing the pressed state of the wire heald B and at the same time dropping it into the area Q. The wire heald B at the front end is pushed by the end portion 20b of the claw portion 20a. As a result, the wire heald B moves below the ring abutment bar 23. Further, the air cylinder 15c is used to raise the magnetic head 12 in the direction of the arrow W, and the magnetic head 12 is moved to a position where the lower end of the magnetic head 12 exceeds the ring portion 7 at the foremost end. Thereafter, the air cylinder 15a is used to horizontally move the magnetic head 12 in the direction of arrow X, and then the air cylinder 15c is used to lower the magnetic head 12 in the direction of arrow Y and the air cylinder 15b is used. Then, the magnetic head 12 is further lowered in the direction of arrow Z. As a result, the magnetic head 12 returns to the position shown in FIG. 5, and the next heald separation preparation is completed.

When the magnetic head 12 is lowered using the air cylinders 15b and 15c, the upper guide rail 9 may be shaken by vibration or the like. Therefore, in order to reliably insert the upper guide rail 9 into the guide rail insertion portion 12c of the magnetic head 12, the upper guide rail 9 is laterally sandwiched by the chuck portion 62 of the steady rest 60 to guide the upper guide rail 9. After positioning the rail 9, the magnetic head 12 is lowered.

Next, another embodiment of the wire-held separation device according to the present invention will be described. FIG. 11 is a perspective view showing another embodiment of the wire-held separation device 40 according to the present invention. The wire-held separation device 40 has substantially the same configuration as the wire-held separation device 10 shown in FIG. Alternatively, the same components are designated by the same reference numerals, and the description thereof will be omitted.

As shown in FIG. 11, the wire-held separating device 40 has a heald extracting member 41 having a structure different from that of the above-mentioned heald extracting member 11. Specifically, the heald extraction member 41 includes a ring retaining member 43 that rotates around a rotation shaft 42 that is bridged between the magnetic heads 12. This ring retaining member 43
Has a rotating arm 43a whose base end is fixed to the rotating shaft 42. The rotating arm 43a extends downward and has a hooking pin 43b at its tip. The heald extraction member 41 has a driving means 44 for driving the rotating shaft 42. The driving means 44 is a rotary solenoid or an air type rotary actuator and is fixed to the base of the magnetic head 12. ing.

Therefore, as shown in FIG. 12, the uppermost ring portion 7 at the front end is pulled upward by the magnetic head 12, and then the driving means 44 is driven as shown in FIG.
By rotating the rotating arm 43 a via the rotating shaft 42, the hooking pin 4 is inserted into the ring portion 7 of the wire heald B.
Insert 3b. As a result, it is possible to prevent the ring portion 7 from falling by sandwiching the uppermost ring portion 7 at the front end with the ring seating recess 13 and the rotating arm 43a. Furthermore, when moving the wire heald B at the foremost end,
Even if the upper ring portion 7 is about to fall off the ring seating recessed portion 13, the ring portion 7 does not drop off from the magnetic head 12 because the ring portion 7 is caught by the hooking pin 43b.

Then, the ring portion 7 at the front end is attracted to the magnetic head 12, and is sandwiched between the magnetic head 12 and the ring retaining member 43, while the magnetic head 12 is being held.
Retreat. During this retreat, as shown in FIG. 14, after the rotating arm 43a is flipped up in the area Q, the current flowing through the coil portion 14 is switched to the demagnetizing AC attenuation current. As a result, while the magnetic coupling force between the ring seating recess 13 and the ring portion 7 is weakened, the residual magnetism generated in the ring portion 7 is removed. In this case, the frontmost ring portion 7 is
It will fall naturally due to vibration or the ring abutment bar 23
And falls from the ring seating recess 13 at the position of the area Q due to the weight of the wire heald B. Then, the wire heald B at the foremost end dropped into the area Q is pushed by the end 20b of the claw portion 20a to move the wire heald B to below the ring abutment bar 23.

In this way, by retracting the magnetic head 12 by a predetermined distance, the wire heald B is pulled so as to be separated from each other even when the mail 6 and the rod portion 5 are intertwined with each other as shown in FIG. The entanglement between the mail 6 and the rod portion 5 is easily eliminated, and the wire heald B at the front end is separated.

The present invention is not limited to the above embodiment. As shown in FIGS. 1 and 15, the wire-held separation device 10 includes auxiliary separation mechanisms 80 and 90 described later.
