DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wire heald separation method and a wire heald separation device, and more particularly to a wire heald separation method used for separating a wire heald located at the forefront end from a large number of wire healds suspended on guide rails. The present invention relates to a wire-held separation device.

[0002]

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 pulling-out operation of the heald performed while suctioning the center of the heald by the nozzle block is 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. 25, the rod portion 1 has a flat and elongated rod portion 1 having a rectangular cross section, and a mail 2 is formed at the center of the rod portion 1. A guide hole 4 having a long hole shape is formed in each ring portion 3. 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) and has an elongated rod portion 5 as shown in FIG. 26, and a mail 6 is formed at the center of the rod portion 5. Ring portions 7 are provided at both ends of the rod portion 5, and each ring portion 7 is formed with a guide hole 8 having a long hole shape. 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.

In order to apply the flat-held separating apparatus disclosed in Japanese Patent Application Laid-Open No. 6-57596 to the wire-held B, the wire-held B is suspended from the guide rail 9 as shown in FIG. As a result, the wire healds B are entangled with each other because of their poor flexibility, and do not line up regularly like the flat healds. Therefore, when the wire heald group is sequentially separated from the foremost end, the wire heald B is made of a thin wire, the uncertainty of the stationary position of the wire heald B, and the like are troubled.
It was difficult to insert the separation claw in between, and it was difficult to insert it securely every time.

Japanese Patent Application Laid-Open No. 64-77653 also discloses a wire heald separation device, in which a separation protrusion is inserted into a predetermined portion of a wire heald group to produce a plurality of wire heald bundles. . However, even in such a wire-held separating apparatus, there is a possibility that the above-mentioned properties of the wire-held B are damaged and the wire-held device cannot 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.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-described problems.

As shown in FIGS. 1 and 6, an upper ring stopper 30 extending in the horizontal direction is provided directly below the magnetic head 12 of the heald drawer 11. The lower end of the magnetic head 12 is urged by a spring 36. Specifically, the upper ring portion stopper 30 has a pair of left and right locking claws 31, and a rod passage slit 32 for passing the rod portion 5 of the wire heald B is formed between the locking claws 31, The rod passage slit 32 extends linearly along the upper guide rail 9.

Further, as shown in FIG. 1 and FIG. 5, the upper ring portion stopper 30 has a support portion 33 for connecting the locking claw portion 31. The support 33 and the frame F
Between the slide table 3 and the mounting table 34 fixed to the
5 are connected. The projecting piece 37 provided at the upper end of the mounting base 34 and the support 33 of the upper ring stopper 30 are connected via a tension spring 36. Therefore, the locking claw 31 of the upper ring portion stopper 30 can be pressed against the lower end of the magnetic head 12 by the tension spring 36, and the locking claw 31 can be made to follow when the magnetic head 12 moves up and down.

Considering that the magnetic head 12 rotates about the support shaft 19, when the magnetic head 12 stops at the uppermost position, the lower end surface of the magnetic head 12 and the locking claw 31
Is preferably separated from the upper end surface. Therefore, the protruding piece 37 is provided with a stop portion 38 protruding toward the support portion 33, and the upper surface of the support portion 33 is brought into contact with the lower surface of the stop portion 38 when the upper ring portion stopper 30 is raised. The upper ring portion stopper 30 can be raised only to a certain extent. Therefore, as shown in FIG. 2, it is possible to separate the lower end surface of the magnetic head 12 from the upper end surface of the locking claw portion 31 by the distance α.
The contact between the magnetic head 12 and the locking claw portion 31 can be avoided at the time of rotation of the magnetic head 12, and the magnetic head 12 can be smoothly rotated. Also, as shown in FIG. 6, the locking claw 31 is formed with a round portion 31a protruding toward the wire heald group. Therefore, even if the next ring portion 7A slightly enters the locking claw portion 31, the next ring portion 7A slides on the round portion 31a and the rod passing slit 32

Above the upper guide rail 9, a plate-like heald lifting stopper 40 extending to the vicinity of the magnetic head 12 is provided.
Is arranged. As shown in FIG. 3, the front end 40a of the heald lifting stopper 40 is located immediately near the ring seating recess 13 and extends parallel to the surface of the magnetic head 12 in a straight line. That is, the heald lifting stopper 40 is extremely close to the magnetic head 12, extends horizontally along the upper guide rail 9, and is disposed immediately above the upper guide rail 9 as shown in FIG. ing.

Therefore, even when the magnetic head 12 is raised in a state where the two ring portions 7 are magnetically attracted to the magnetic head 12, the ring other than the foremost ring portion 7 accommodated in the ring seating recess 13 is used. The part 7 is a heald lifting stopper 40
And the extra ring portion 7 is not taken out. Thus, the heald lifting stopper 40
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 rising stopper 40 is located on the side surface 12 b of the magnetic head 12.
(See FIG. 4), the ring seat recess 13
The ring part 7 housed in the heald lifting stopper 40
The magnetic head 12 can be moved up without fail. In addition, the heald lifting stopper 4
0 is desirably a material that is not strongly magnetized by the magnetic head 12 (for example, SUS304).

As shown in FIG. 1, the above-mentioned wire-held separating apparatus 10 has a lower ring-part push-out member 10B for separating the lower ring part 7 of the frontmost wire-held B. The push-out member 10B is disposed between the heald guide portion 23 and the lower guide rail 9, and is exposed on the lowermost ring portion 7 of the foremost end exposed after the foremost wire heald B is pulled up by the magnetic head 12. A pair of left and right pushing claws 51 extending horizontally to push the upper end portion forward from the heald group side, a rod passage slit 52 formed between the pushing claws 51 and extending along the guide rail 9, It has a base 53 surrounding the guide rail 9 and supporting and connecting the pushing claws 51, and a driving means 54 as an air cylinder fixed to the frame F and moving the base 53 forward and backward.

The driving means 54 comprises two first and second driving means.
The driving means is constituted by a combination of the air cylinders 55 and 56. The slider portion 55a of the first air cylinder 55 is fixed to the base 53, and the slider portion 56a of the second air cylinder 56 is
The main body of the second air cylinder 56 is fixed to the frame F. The first air cylinder 55 is used when the push-out claw 51 pushes the lower ring portion 7 at the foremost end to separate the foremost wire heald B, and the second air cylinder 56 is used for the above-described upper 2
Synchronous with the air cylinder 29.

Also, below the lower guide rail 9,
A lower ring portion stopper 57 facing the lowermost ring portion 7 at the front end is disposed. The lower ring portion stopper 57 is fixed to the frame F, and engages with the lower end portion of the next lower ring portion 7A exposed when the frontmost wire heald B is lifted, thereby pushing the pushing claw 51. This is for restricting the movement of the next lower ring portion 7A when the vehicle moves forward. In other words, the lower ring portion 7 of the foremost wire heald B has the top portion 57 of the lower ring portion stopper 57 in a state before the foremost wire heald B is lifted.
a (see FIG. 7), and in a state after the foremost wire heald B has been lifted, the wire heald B is lifted high over the top 57a (see FIG. 11). Therefore, only the lower ring portion 7 of the lifted frontmost wire heald B can pass through the lower ring portion stopper 57. Then, after raising the magnetic head 12 and pulling out the foremost wire heald B upward, the upper end portion of the lowermost ring portion 7 of the foremost end can be pushed out by the pushing claw 51. The side ring portion stopper 57 can restrict the movement of the next lower ring portion 7A.

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

First, as shown in FIGS. 7 and 8, with a large number of wire healds B suspended from the guide rail 9, the ring seating concave portion 13 of the magnetic head 12 faces the uppermost ring portion 7 at the forefront end. Let it. Then, FIG. 9 and FIG.
As shown in FIG. 3, the heald group is urged in the direction of arrow P by compressed air or the like, so that the ring seat recess 1
The uppermost ring 7 at the front end is pressed against 3, and this ring 7 is seated on the magnetic head 12. At this time, the locking claw portion 31 is urged upward by the spring force of the tension spring 36 and is pressed against the lower end surface of the magnetic head 12. When the uppermost ring portion 7 at the forefront end is seated in the ring seating recess 13, the foremost wire heald B
Is slightly inserted into the rod passage slit 32 (see FIG. 6).

In this state, the magnetic attraction D
By passing the C current, the upper ring portion 7 at the forefront end is magnetically attracted to the ring seating recess 13. Then, FIG.
As shown in FIG. 12 and FIG. 12, the heald drawer 11 is raised in the direction of the arrow U by using the air cylinder 15 (see FIG. 1), so that the uppermost ring part 7 at the forefront end becomes the upper guide rail 9. It rises while being inserted in. Then, as shown in FIG. 2 and FIG.
Is exposed. At this time, even when the next ring portion 7A is lifted by being lifted, the next ring portion 7A is not raised by being blocked by the heald rising stopper 40.

When pulling up the frontmost wire-held wire B, as shown in FIG. 13, even if the mails 6 are entangled with each other, as shown in FIG.
14, the mail 6 and the rod 5 are entangled as shown in FIG. That is, mail 6
Is difficult to be elastically deformed, so that the entanglement between the mails 6 is difficult to be eliminated, whereas the rod portion 5 is easily elastically deformed. Will be resolved.

Here, as shown in FIGS. 2 and 12, when the magnetic head 12 stops at the uppermost position,
Is separated from the upper end surface of the locking claw portion 31 by a predetermined distance α. This means that the top surface 33a of the support portion 33 extending from the locking claw portion 31 while the magnetic head 12 is being lifted.
This is achieved by abutting the stop portion 38 with the spring force of the tension spring 36, thereby enabling the subsequent smooth rotation of the magnetic head 12.

Thereafter, as shown in FIGS. 15 and 16,
The first air cylinder 28 (see FIG. 1) is driven to advance the ring portion pusher 24 toward the magnetic head 12, so that the hook piece 25 is inserted into the guide rail insertion portion 12c between the magnetic heads 12, and The curved top 7a of the ring 7 at the front end is inserted between the claws 25a, 25b.
As a result, the magnetic head 12 serves as a lid, and the upper ring portion 7 at the forefront end is engaged with the hook piece 25 of the ring portion pusher 24.

By engaging a guide roller 73 fixed to the rear surface of the rear plate with a roller guide groove 74 formed in the vertical direction in the back plate 72, the heald separation finger 71 can slide in the vertical direction. And back plate 7
The tip of the rod 75 a of the air cylinder 75 as a driving means fixed to 2 is rotatably fixed to the surface of the heald separation finger 71. Therefore, by expanding and contracting the rod 75a, the heald separation finger 71 can be moved up and down along the extending direction of the roller guide groove 74.

The roller guide groove 74 is bent outward at the upper portion to achieve swing of the claw portion 71a. That is, the guide roller 73 is
When the heald separation finger 71 is pulled right below the rod 75a with the rod 75a in a state where the guide roller 73 moves along the bent portion 74a of the roller guide groove 74, the heald separation finger 71 shakes the The part 71a falls forward. At this time, as shown in FIG. 17, the claw portion 71a is inserted between the rod portion 5 of the frontmost wire heald B and the rod portion 5 of the next wire heald B.

By continuing to pull the heald separation finger 71 directly below the rod 75a, the guide roller 73 descends along the hanging part 74b of the roller guide groove 74, and the state where the claw part 71a is tilted forward is maintained. The heald separation finger 71 descends while moving. At this time, as shown by a two-dot chain line in FIG. 17, when the rod portions 5 are entangled with each other to form an X shape, the rod portions 5 are forcibly torn.
The frontmost wire heald B can be reliably separated over the entire length. In consideration of the next separating operation, the rod 75a is extended, the guide roller 73 is positioned at the uppermost end of the roller guide groove 74, and the claw portion 71a is returned to the original position.

Further, the wire-held separation device 10 may be provided with a guide rail steadying means (not shown) for preventing the upper guide rail 9 from swinging due to vibration or the like. The steadying means (not shown) is provided on the upper guide rail 9.

Is configured as When the upper guide rail 9 oscillates due to vibration or the like, the anti-sway means uses the upper guide rail 9 at the chuck portion.
Is used so as to be sandwiched from the side. In particular, when the magnetic head 12 is rotationally inserted into the upper guide rail 9, it is effective when the upper guide rail 9 is securely inserted into the guide rail insertion portion 12 c of the magnetic head 12. Further, when the upper guide rail 9 is inserted into the guide rail insertion portion 12c, it is also effective when the guide rail 9 is in contact with the magnetic head 12 so as not to wear them.

The above-mentioned wire-held separation device 10
Means a plurality of guide rails 9 (for example, 16 or 24)
Needless to say, it can also be applied to the case where they are juxtaposed.
For example, when the devices shown in FIG. 1 are arranged for each guide rail 9, these devices may be driven independently or may be synchronized. When synchronizing this device, the locking pin M shown in FIG. Each locking pin M is disposed immediately below the locking claw 31 just before the wire heald B at the forefront end (see FIG. 7). Each locking pin M is moved in the Y direction by using an air cylinder, a link mechanism, or the like (not shown), so that the tapered portion Ma of the locking pin M is formed.
Is in contact with the rod portion 5 of the wire heald B at the front end. As a result, the frontmost wire heald B is slightly retracted by the tapered portion Ma, and the advance of the wire heald B is regulated by the locking pin M. Therefore, the wire heald B at the forefront end, the movement of which is restricted by the locking pin M, does not sit in the ring seating recess 13 of the magnetic head 12 whether or not the magnetic head 12 is magnetized.

Therefore, at the portion corresponding to the group of healds that need to be separated among the group of healds suspended from the plurality of guide rails 9, the locking pin M is retracted, and the wire heald B is held by the locking pin M. By releasing the movement restriction, only the ring portion 7 of an arbitrary wire heald B can be seated in the ring seat recess 13 of the magnetic head 12, and the wire heald B is lifted and separated.

As described above, by utilizing the locking pin M, the drawer pusher 26, the roller 26a, and the hook 25 provided for the plurality of guide rails 9 are provided.
And the like can be moved together by one driving means 27. That is, the forward movement of the wire heald B can be restricted by the locking pin M, so that the ring part 7 of the wire heald B at the foremost end is the ring seat recess 1 of the magnetic head 12.
3, and the frontmost wire heald B is not raised by the magnetic head 12. Therefore, even if all the pushing members 10A are simultaneously driven, the magnetic head 12 causes the wire-held B
As long as is not raised, there is no influence of the pushing member 10A.

When a plurality of magnetic heads 12 are arranged corresponding to a plurality of guide rails 9, the support shaft 19 shown in FIG.
The plurality of magnetic heads 12 can be arranged on a single support shaft 19 by extending the through holes so that the magnetic heads 12 can be driven simultaneously.
