Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wire heald pulling-out method and pulling-out apparatus for pulling out the wire heald located at the end from a heald group composed of a large number of wire healds arranged in parallel.

[0002]

2. Description of the Related Art As an example of a conventional heald drawing device, there is Japanese Patent Publication No. 60-22097. The heald extraction device disclosed in this publication presses a suction nozzle with a magnet against the rod portion of the heald at the end of the heald group held by the horizontally extending upper and lower guide rails, and the magnetic force of the suction nozzle. And a suction force pulling the rod part away from the heald group, and transporting the endmost wire heald to a predetermined location.

[0003]

However, the above-described technique is a drawing device used for a flat heald having a flat plate-shaped rod portion, and is not a drawing device for a wire heald. That is, the flat heald A is integrally formed of SUS420 or the like having a spring property, and as shown in FIG. 41, has a flat elongated rod portion 1 having a rectangular cross section, and a mail 2 is formed in the center of this rod portion 1. Further, ring portions 3 are provided at both ends of the rod portion 1, and each ring portion 3 is provided with a guide hole 4 having a long hole shape. The flat heald A has a characteristic that it easily bends in the direction of the arrow, but has a characteristic that it is strong against twisting and difficult to deform, and even when the heald group is formed by the guide rails, it is always aligned regularly without being entangled. Therefore, the suction nozzle with a magnet can be pressed against the flat plate-shaped rod portion, and the healds can be appropriately pulled out sequentially from the front end of the heald group by the magnetic force and the suction force of the suction nozzle with a magnet.

On the other hand, the wire heald B is made of hard steel wire (60 carbon) or the like and has an elongated rod portion 5 as shown in FIG. 42, and a mail 6 is formed in the center of this rod portion 5. And the ring portions 7 are provided at both ends of the rod portion 5,
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, if the flat-held drawing device disclosed in Japanese Patent Publication No. 60-22097 is applied to the wire-held B, the wire-held B is utilized by utilizing the suction force or magnetic force of the suction nozzle with a magnet. To pull out the rod part, the rod part is too thin and it cannot be pulled out efficiently.

Further, Japanese Patent Application Laid-Open No. 64-77653 also discloses a wire-held drawing device, in which the separating protrusion is inserted into a predetermined position of the wire-held group to separate a plurality of wire-held bundles. By moving the protrusion, the wire heald B is conveyed to a predetermined place. However, even in such a drawing device, there is a concern that the easiness of entanglement of the wire heald B may be affected and an arbitrary wire heald B may not be drawn appropriately.

The present invention has been made to solve the above problems, and particularly provides a wire-held pulling-out method and a wire-held pulling-out apparatus for surely pulling out the endmost wire heald from a group of wire healds. The purpose is to do.

[0008]

A wire-held drawing method according to the present invention is a wire-held drawing method for drawing out an arbitrary wire-held in a state where a large number of wire-helds made of a magnetic material are arranged in parallel. After inserting the extraction pin provided at the tip of the magnetic head into the guide hole formed in the ring part on the side, magnetically attract the ring part of the end of the wire heald to the tip surface of the magnetic head, and then Is moved in the extending direction of the wire heald, and the endmost wire heald is hooked on the pull-out pin and pulled out.

In this drawing-out method, the drawing-out pin is inserted into the guide hole of the ring section by bringing the tip of the magnetic head close to the ring section of the endmost wire heald made of a magnetic material. Then, by passing an exciting current through a coil arranged around the magnetic head, the ring portion is magnetically attracted to the tip end surface of the magnetic head, and the ring portion is fixed to the magnetic head. Then, the wire head can be smoothly pulled out by moving the magnetic head in the extending direction of the wire heald while hooking the ring portion on the pull-out pin. Moreover, when the drawing of the wire heald is completed, the current to the coil arranged around the magnetic head is switched to, for example, a degaussing AC attenuation current, so that the ring portion is demagnetized by the magnetic head and the ring portion is demagnetized. Can be released from. The extending direction of the wire heald described above is, for example, a vertical direction when the wire heald groups are arranged in parallel in the horizontal direction, and a horizontal direction when the wire heald groups are arranged in the vertical direction. is there.

In this case, the outermost wire heald is pulled out, the ring portion of the outermost wire heald is displaced with respect to the ring portion of the next wire heald, and then the outermost wire heald is exposed toward the exposed one ring portion of the next wire. From the other side in the heald stacking direction, while pushing the rod part of the wire heald at the end between the push-back claws, press the next ring on the one side in the heald stacking direction. It is preferable to separate the ring portion on one side of the end from the ring portion on the next side. When such a method is adopted, it is possible to reduce the contact pressure between the outermost wire heald that is pulled out and the next wire heald, so it is possible to reduce the friction when the outermost wire heald is pulled out. The tendency of the wire heald to be pulled out can be reduced, and the wire heald can be pulled out more smoothly. Moreover, since the tension applied to the outermost wire heald can be reduced, the deformation of the outermost wire heald is eliminated and the life of the outermost wire heald is extended.

Also, pull out the outermost wire heald,
After displacing the ring portion of the endmost wire heald with respect to the ring portion of the next wire heald, move the push-back member from the outside toward the heald stacking direction toward the exposed ring portion on the other side of the next wire, It is preferable that the push-back member presses the next-side ring portion in the heald stacking direction to separate the end-most other-side ring portion from the next-side other-side ring portion.
When such a method is adopted, the outermost wire heald to be pulled out and the next wire heald can be separated over substantially the entire length by the cooperation with the push-back claw described above, and therefore the outermost wire heald is pulled out. Can be pulled out extremely smoothly.

Further, while the wire head is being pulled out by the magnetic head, a drop-out preventing portion is placed so as to cover the tip of the pull-out pin, and the ring portion is pulled out to the pull-out pin by engaging the pull-out pin and the drop-out preventing portion. After hanging and holding, it is preferable that the magnetic head and the drop-out preventing portion are simultaneously moved in the pull-out direction, and the pull-out preventing portion and the pull-out pin are disengaged after pulling out the endmost wire heald. When such a method is adopted, since the ring portion can be sandwiched between the magnetic head and the drop-out preventing portion, the ring portion does not come off from the pull-out pin during pulling out the wire heald.

Further, after the completion of drawing out the wire heald at the end, in the state where the ring portion of the wire heald is magnetically attracted to the magnetic head, an AC damping current for degaussing is caused to flow through a coil arranged around the magnetic head, It is preferable to demagnetize the ring portion magnetized by (1) to release the ring portion from the magnetic head. When such a method is adopted, the ring portion magnetized by the influence of the magnetic head during the drawing of the wire heald can be demagnetized by the magnetic head and released from the magnetic head. Therefore, since the magnetism remaining in the wire heald after being pulled out can be eliminated, it is possible to eliminate the phenomenon that the wire healds are close to each other in the weaving process in the automatic loom, and the reuse of the wire heald is not affected. .

In the wire-held drawing device according to the present invention, in a wire-held drawing device for drawing out any wire heald in a state in which a large number of wire healds made of a magnetic material are juxtaposed, the wire-held drawing device is formed on a ring portion at one end of the wire heald. A magnetic head made up of an iron core of an electromagnet, and a pull-out pin fixed to the tip of the magnetic head and inserted into the guide hole of the ring portion, extending in the pull-out direction of the wire heald. And a first drive means for holding the magnetic head via the moving base,
Second drive means is provided, which is fixed to the moving base and moves the magnetic head toward the ring portion and inserts the extraction pin into the guide hole of the ring portion.

In this drawing apparatus, the second driving means is used to bring the tip end surface of the magnetic head close to the end of the wire heald ring made of a magnetic material.
Insert the extraction pin into the guide hole of the ring. Then, by passing an exciting current through a coil arranged around the magnetic head, the ring portion is magnetically attracted to the tip end surface of the magnetic head, and the ring portion is fixed to the magnetic head. After that, by moving the moving base in the wire-held drawing-out direction by the first driving means, the wire-held can be smoothly drawn out in the wire-held extending direction while the ring portion is hooked on the drawing-out pin. Moreover, when the drawing of the wire heald is completed, the current to the coil arranged around the magnetic head is switched to, for example, a degaussing AC attenuation current, so that the ring portion is demagnetized by the magnetic head and the ring portion is demagnetized. Can be released from. In addition, the extending direction of the wire heald described above,
For example, it is the vertical direction when the wire heald groups are arranged in parallel in the horizontal direction, and is the horizontal direction when the wire heald groups are arranged in the vertical direction.

In this case, after facing the ring portion on one side of the outermost wire heald, pulling out the outermost wire heald, and shifting the ring portion of the outermost wire heald with respect to the ring portion of the next wire heald. , The push-back claw that moves in the heald stacking direction toward the exposed next-side ring part and pushes the next-side one-side ring part with the tip claw part and the push-back claw It is preferable to further include a drive unit for moving the push-back claw in the direction, and the claw portion of the push-back claw preferably pushes the next ring portion on one side after passing the rod portion of the endmost wire heald during movement. When such a configuration is adopted, it is possible to reduce the contact pressure between the outermost wire heald and the next wire heald that are pulled out, so that it is possible to reduce friction when the outermost wire heald is pulled out,
The tendency of the next wire heald to be taken out can be reduced, and the wire heald can be pulled out more smoothly. Moreover, since the tension applied to the outermost wire heald can be reduced, the deformation of the outermost wire heald is eliminated and the life of the outermost wire heald is extended.

Further, after facing the ring portion on the other side of the outermost wire heald, pulling out the outermost wire heald, and shifting the ring portion of the outermost wire heald with respect to the ring portion of the next wire heald. , The push-back member that moves in the heald stacking direction toward the exposed next-side ring part and pushes the next-side ring part at the tip end in the heald-stacking direction It is preferable to further include a driving unit for driving the driving unit. In the case of adopting such a configuration, the outermost wire heald to be pulled out and the next wire heald can be separated over substantially the entire length by the cooperation with the push-back claw described above, and thus the outermost wire heald is separated. Can be pulled out extremely smoothly.

Further, it is arranged in front of the drawing direction of the wire heald, facing the drawing pin and provided on the moving base, and engages with the drawing pin during the drawing of the wire heald, and draws the ring portion with respect to the drawing pin. It is preferable to further include a drop-out preventing portion for hanging and holding. When such a configuration is adopted, the ring portion can be sandwiched between the magnetic head and the drop-out preventing portion, and the ring portion does not come off from the pull-out pin during pulling out the wire heald.

In this case, it is preferable that the drop-out preventing portion is arranged on the moving base so as to be movable in the drawing direction of the wire heald so as to release the engagement with the drawing pin. By adopting such a configuration, after the outermost wire heald is completely separated from the wire heald group, the ring portion formed by the magnetic head and the drop-off preventing portion can be appropriately released.

BEST MODE FOR CARRYING OUT THE INVENTION Preferred embodiments of a wire-held drawing method and drawing apparatus according to the present invention will be described in detail below with reference to the drawings.

FIG. 1 is a perspective view showing a wire-held pulling-out device applied to a flat type double-stock wire-stocker stocker, and FIG. 2 shows one of the double-stocker stockers shown in FIG. FIG. As shown in FIGS. 1 and 2, the wire-held stocker 10 includes:
It has a housing 11 in which the wire healds B made of a magnetic material such as hard steel wire (60 carbon) are placed in the horizontal direction and stacked vertically. The housing 11 is formed to be elongated according to the elongated shape of the wire heald B, and
It is provided with a flat base 12, a frame body 13 which is erected and fixed on the base 12, and a heald outlet 9 which is horizontally elongated and cut out at the lower front end. This frame 13
Are located at both ends of the ring housing portion 14 for housing the ring portion 7 of the wire heald B, and these ring housing portions 1
And a rod accommodating portion 15 for accommodating the rod portion 5 of the wire-held B.

A rod-shaped floating rod 16 extending in the vertical direction is inserted into each ring accommodating portion 14, and the outer peripheral shape of each floating rod 16 is substantially matched with the inner peripheral shape of the ring portion 7, whereby the lowermost wire heald Each time B is pulled out, the ring portion 7 of the wire heald B can be naturally dropped along the floating rod 16, enabling stable stacking of the wire heald B. The floating rod 16 is lightweight, and its surface is mirror-finished so that the wire heald B is slippery, and is subjected to abrasion-resistant surface treatment so that the wire heald B does not easily get scratched. For example, there is a floating rod 16 in which the surface of metal or the like (stainless steel, aluminum, plastic, etc.) processed into a predetermined shape is hard chrome plated. The floating rod 16 is preferably made of a material that is hard to be magnetized.
This is because when the floating rod 16 is magnetized due to the influence of a magnetic head 91, which will be described later, disposed near the floating rod 16, the stacked ring portions 7 are magnetically attracted to the floating rod 16 and ring along the floating rod 16. This is because it is difficult for the portion 7 to fall naturally.

As another example of the material of the floating rod 16, ceramic, hard glass, aluminum vapor-deposited ceramic, plastic vapor-deposited ceramic, SUS304 vapor-deposited ceramic, and the like are preferable.

As shown in FIG. 3, the lower end surfaces 16a of the front and rear floating rods 16 are brought into contact with the heald receiving bottom surface 12a formed on the surface of the base 12, and the floating rod 16 is attached to the heald receiving bottom surface 12a by its own weight. It is pressed. That is, since the floating rod 16 is simply inserted into the ring accommodating portion 14 from above, the floating rod 16 is free in the vertical direction with respect to the base 12. Therefore, the floating rod 16
Can be moved in the vertical direction (the direction of the arrow) in the ring accommodating portion 14 of the housing 11.

As an effect of using the floating rod 16, the weight of the stacked wire healds B allows the wire healds B to be vertically aligned in the correct order, and at the same time, the state can be maintained at all times. The entanglement between the ring portions 7 of the wire heald B can be eliminated. Furthermore, since the ring portion 7 can be kept horizontal by the floating rod 16, the horizontal drawing of the wire heald B becomes extremely easy.

The floating rod 16 is simply in contact with the heald receiving bottom surface 12a of the base 12 due to its own weight. Therefore, when the wire heald B at the bottom is pulled out horizontally, the wire heald B
When the ring portion 7 of the floating rod 16 bites into a tapered ring retracting portion 16c (see FIG. 14) of the floating rod 16 described later, the lower end surface 16a of the floating rod 16
Can be easily pushed up. As a result, only the ring portion 7 being pulled out is pulled out while being sandwiched between the lower end surface 16a of the floating rod 16 and the heald housing bottom surface 12a. Therefore, the ring portion 7 of the wire heald B other than during the drawing operation maintains the state in which the floating rod 16 is still inserted, and only the wire heald B during the drawing is pulled forward while pushing the floating rod 16 upward. Become.

Further, as shown in FIG. 2, the ring accommodating portion 1
In order to accommodate the ring parts 7 in a stacked state,
A ring accommodating space 14a extending vertically is formed. The upper part of the ring accommodating space 14a is opened for inserting the floating rod 16, and one side of the ring accommodating space 14a is opened as a notch for inserting the rod part 5 of the wire heald B. . The ring accommodating space 14a is formed so as to surround the floating rod 16, so that the floating rod 16 is supported by the ring accommodating portion 14 via the ring portion 7 of the wire heald B, while the ring accommodating portion 14a is supported. It can be reliably accommodated in 14.

As shown in FIGS. 2 and 4, the housing 1
At the center of 1 is an elongated rod accommodating slit 1 for accommodating a rod portion 5.
7 is formed in the longitudinal direction. This rod accommodation slit 1
7 is provided on a straight line connecting the ring accommodation spaces 14a at both ends. That is, the rod accommodating slit 17 is formed in the entire length of the rod accommodating portion 15 and a part of the ring accommodating portion 14. At the lower end of the rod accommodating slit 17, the ring portion 7 of the lowermost wire heald B is attached to the bottom of the heald accommodating bottom 12.
Ring guide hole 1 for sure guide sliding along a
8 are formed.

The ring guide hole 18 is formed right above the heald housing bottom surface 12a so as to horizontally extend the lower end of the rod housing slit 17, and is slightly larger than the width of the ring portion 7. It has such a height that only the lowermost ring portion 7 can pass through. Since the ring guide hole 18 is formed over the entire length of the rod accommodating slit 17, the wide ring portion 7 does not get caught in the housing 11. Moreover, even when the used wire heald B in which the ring portion 7 is slightly twisted with respect to the rod portion 5 is pulled out in the horizontal direction, the wire heald B can be pulled out stably in the horizontal direction regardless of the twist of the ring portion 7. You can Further, when the lowermost wire heald B is pulled out, the ring portion 7 on the rear side of the lowermost wire heald B is prevented from cutting into the rod portions 5 stacked in the rod accommodating slit 17.

As shown in FIGS. 2 and 6, the housing 1
The first rod accommodating portion 15 is divided into two parts in the front and rear, and is composed of a first rod accommodating portion 15A and a second rod accommodating portion 15B. The first rod accommodating portion 15A and the second rod accommodating portion 15B
By fixing the rod accommodating portion 15 on the base 12 so as to separate the mail accommodating space portion 19 and the mail accommodating space portion 19 from each other.
Can be And this mail storage space 1
Even if mail 6 is piled up on 9, mail storage space 1
Since 9 has a large space, the degree of freedom for moving the mail 6 vertically and horizontally can be increased. Further, a heald escape recess 20 for expanding the lower portion of the mail accommodating space portion 19 is formed on the heald accommodating bottom surface 12a.
That is, the lower part of the mail 6 at the bottom is opened by the heald escape recess 20.

Therefore, as shown in FIG. 5, when the upper and lower mails 6 are entangled with each other and the wire heald B is turned upside down in the vicinity of the mail 6, as shown in FIG. When B is pulled out in the horizontal direction, as shown in FIG. 7, the ring portion 7 and the mail 6 which are being pulled out collide with each other, and the entanglement between the wire healds B is eliminated while escaping each other. In addition, the first rod accommodating portion 15A and the second rod accommodating portion 15B that form the mail accommodating space portion 19
By making the interval δ (see FIG. 2) between the second rod accommodating portion 15B and the ring guide hole 18 of the second rod accommodating portion 15B shorter than the length of the ring portion 7, the rearmost end of the ring portion 7 can accommodate the mail. The front end of the ring portion 7 (the connecting end of the ring portion 7 and the rod portion 5) can be drawn into the first rod accommodating portion 15A before it completely comes off in the region of the space portion 19. as a result,
In the mail accommodating space portion 19, it is possible to stably convey the ring portion 7 while keeping the ring portion 7 horizontal, and it is possible to reliably escape the mail 6 entangled in the wire heald B being pulled out.

As shown in FIG. 2, at the top of the frame body 13 of the housing 11, there is provided a heald refilling opening 21 extending in the horizontal direction. The heald refilling opening 21 allows the wire heald B to move horizontally. Held outlet 9 for pulling out
It is provided in a position different from. Therefore, in the refilling work of the wire heald B, the refilling work can be carried out from above the housing 11 by using the wire heald refilling magazine (not shown) or the like while utilizing the compressed air, the weight of the wire heald B or the like. Work becomes easy. Further, refilling work can be performed by looking into the opening 21 from above. Further, the upper part of the rod accommodating slit 17 provided in the rod accommodating portion 15 of the frame body 13 is widened in a funnel shape so that the wire heald B can easily enter the rod accommodating slit 17.

As shown in FIG. 8, an air outlet 22 for supplying compressed air from the outside into the ring accommodating space 14a is provided above the front and rear ring accommodating portions 14,
Each of the air outlets 22 blows compressed air from diagonally above toward the front and rear floating rods 16. Further, an air receiving concave portion 23 cut into an L-shaped cross section is formed on the upper portion of the floating rod 16,
The air receiving recess 23 is provided at a position facing the air outlet 22.

Therefore, the compressed air blown out from the air outlet 22 continues to push the air receiving concave portion 23 obliquely from above, so that a predetermined downward pressure can be continuously applied to the floating rod 16 and the wire heald B at the lowermost stage.
However, the floating rod 16 is appropriately prevented from jumping up when being pulled out while being sandwiched between the lower end surface 16a of the floating rod 16 and the heald housing bottom surface 12a. Further, since a downward airflow is generated in the ring accommodating space 14a and the airflow can keep pushing the ring portion 7 from above, the ring portion 7 is forced along the floating rod 16 every time the wire heald B is pulled out. Floating rod 16
It is possible to prevent the ring portion 7 from being caught and stopped.

Further, an air suction part 24 for forcibly discharging the air in the ring storage space 14a to the outside is provided in the lower part of the ring storage part 14 on the rear side. The lower ring portion 7 attached to the floating rod 16 is sucked rearward. The rearward suction by the air suction unit 24 is intended for several wires from below the stacked wire healds B, and the suction port 24a of the air suction unit 24 is expanded inward in a funnel shape. . Therefore, by using the air suction portion 24, the air in the ring housing space 14a can be continuously sucked, and several ring portions 7 from the bottom can be continuously pulled backward. Therefore, when the lowermost wire heald B is forcibly pulled out, the wire heald B being pulled out is less likely to be taken out together with the upper wire heald B, and the wire heald B can be pulled out reliably and smoothly.

Next, a pull-out device 90 for pulling out the magnetically-held wire healds B vertically stacked in the stocker 10 one by one from the lowermost stage will be described.

As shown in FIGS. 1 and 9 to 12, a wire-held pull-out device 90 according to the present invention includes a magnetic head 91 for pulling a heald, which is vertically movable and is made of an iron core which constitutes a part of an electromagnet. A pull-out pin 94 made of a non-magnetic material provided on the top of the magnetic head 91 and the magnetic head 91.
It has a rectilinear unit 92 as a first driving means for moving the head in the horizontal direction and a piston mechanism 93 as a second driving means for vertically moving the magnetic head 91.

As shown in FIG. 13, the magnetic head 91 is
In order to pull out the wire heald B at the lowermost stage, it faces the guide hole 8 formed in the front ring portion 7 at the lowermost stage and is arranged in front of the base 12 below the floating rod 16 at the front side. Further, a pull-out pin 94 made of a non-magnetic material is fixed to the tip (top end) of the magnetic head 91. The pull-out pin 94 is inserted into the guide hole 8 and is slightly smaller than the height H of the ring portion 7. Very low height K
have. Therefore, the wire heald B can be pulled out while hooking the pull-out pin 94 only on the lowermost ring portion 7.

Further, as shown in FIGS. 1 and 13, the front ring accommodating portion 14 is provided with a multiple withdrawal preventing portion J located in front of the front floating rod 16. A plate-like switch piece 95 that is rotatable is provided in the multiple-draw-out preventing portion J.
It is accommodated in a slit-shaped switch piece accommodating portion 96 formed at the lower front end of the ring accommodating portion 14. Further, the engaging portion 95a provided at the tip of the switch piece 95 is arranged so as to face the ring accommodating space 14a, and
It is positioned so as to face the ring portions 7 in the second or more stages from the bottom except the ring portion 7 in the lowermost stage.

This switch piece 95 is used for the ring accommodating portion 14
It is rotated about a rotating shaft 97 which is fixed to and is pressed against the regulating wall 96a of the switch piece accommodating portion 96 by a torsion coil spring 98. This torsion coil spring 98
Is wound around a support bar 99 fixed to the ring accommodating portion 14, and one end of the torsion coil spring 98 has a switch piece 95.
, And the other end is in contact with the ring accommodating portion 14. Therefore, the switch coil 95 can be constantly urged against the restriction wall 96a by the torsion coil spring 98. Further, a heald outlet 9 is formed between the lower end surface 95b of the switch piece 95 and the tip end surface 91a of the magnetic head 91. The heald outlet 9 is only the lowermost wire heald B hooked on the leader pin 94. However, it has a height dimension α that can barely pass through.

Therefore, while the lowermost ring portion 7 is magnetically attracted to the tip surface (adsorption surface) 91a of the magnetic head 91,
When the lowermost ring portion 7 is hooked by the pull-out pin 94 and the lowermost wire heald B is pulled out horizontally, the second or more lower wireheld B may be pulled out together due to friction. At this time, the other wire heald B taken out by the lowermost wire heald B collides with the engaging portion 95a of the switch piece 95 biased by the predetermined spring force of the torsion coil spring 98 and is pushed back. As a result, only the lowermost wire heald B is pulled out from the heald outlet 9. Further, when the extra wire heald B is taken out beyond the biasing force of the torsion coil spring 98, the extra wire heald B other than the lowermost stage is used.
Since the switch 5 is continuously pressed, the switch piece 95 continues to rotate as shown by the chain double-dashed line, and a predetermined detection means (for example, an optical sensor).
Thus, the rotation of the switch piece 95 is detected, and the forward movement of the magnetic head 91 by the straight advance unit 92 is stopped.

Incidentally, as shown in FIGS. 13 and 14, in order to properly insert the pull-out pin 94 into the guide hole 8 of the lowermost ring portion 7, the front floating rod 16 is inserted.
In the front part of the lower end surface 16a in the above, a notch portion 16b for inserting the pull-out pin 94 from below is provided. Further, a tapered ring lead-in portion 16c is formed at the rear portion of the lower end surface 16a of the floating rod 16,
The ring retracting portion 16c allows the front ring portion 7 being pulled out to move toward the lower end surface 16 of the front floating rod 16.
It can be easily pulled in between a and the bottom surface 12a of the heald housing. However, as the floating rod 16 on the rear side, the floating rod 16 without the notch 16b for the pull-out pin may be adopted.

As shown in FIGS. 1 and 9 to 12, the pull-out device 90 includes a rectilinear unit 9 as a first driving means for moving the above-described magnetic head 91 in the horizontal direction.
Two. This straight-moving unit 92 is a stocker 1
It is laid below 0 and is arranged adjacent to a support base 61 for supporting the base 12 of the housing 11. Further, the rectilinear unit 92 is housed in the main body 92A and is also housed in the main body 92A and a guide rail 92a laid in the extending direction of the wire heald B, a table 92b sliding along the guide rail 92a. It is composed of a drive mechanism 92c for moving the table 92b. In addition, the drive mechanism 92c includes the guide rail 9
Screw shaft 92cA extending along 2a, and screw shaft 92c
It includes a nut portion (not shown) that is screwed into A and is fixed to the table 92b, and a servo motor 92d that drives a screw shaft 92cA. Therefore, by driving this servo motor 92d, the guide rail 92
The table 92b can be moved back and forth along a.
In addition, since the stop position of the table 92b is electrically controlled by the control system, it is possible to sufficiently cope with various wire healds B. The straight traveling unit 92 may be a linear motor guide.

A lower portion 110c of the moving base 110 is fixed on the table 92b, and a supporting portion 91A of the magnetic head 91 is mounted on the upright portion 110a of the moving base 110. The supporting portion 91A is provided on the upright portion 110a. It slides up and down along the formed guide groove 111. A piston mechanism 93 as a second driving means is vertically installed and fixed to the lower portion 110c of the moving base 110.
The piston rod 93a of the
A. Therefore, the piston mechanism 93 moves forward and backward together with the moving base 110, and the magnetic head 9 moves.
1 can be moved up and down. Then, by projecting the piston rod 93a upward, the magnetic head 91 can be moved toward the ring portion 7, and the extraction pin 94 can be inserted into the guide hole 8 of the ring portion 7.

Further, as shown in FIGS. 1 and 15 to 17, the upper portion 110b of the moving base 110 is engaged with the pull-out pin 94 during the pulling-out of the wire heald B, and is at the lowest stage with respect to the pull-out pin 94. A fall prevention mechanism 112 for holding the hook of the ring portion 7 is arranged. The drop-out prevention mechanism 112 is disposed in front of the wire heald B in the drawing direction, facing the drawing pin 94 and provided on the upper portion 110b of the moving base 110, and engages with the drawing pin 94 during the drawing of the wire heald B. , A plate-shaped fall-out preventing portion 113 for holding the hook of the ring portion 7 with respect to the pull-out pin 94, a moving base portion 114 for holding the fall-out preventing portion 113 on the moving base 110, and the moving base portion 114 for the moving base 110. Linear guide 115 that slides and guides on the upper portion 110b of the moving base 110, a piston mechanism 116 that is fixed to the upper portion 110b of the moving base 110 to move the moving base 114 forward and backward, the moving base 114 and the moving base 11
Tension spring 11 hung between the upper part 110b
It consists of 7.

Further, the push portion 116 provided at the tip of the piston rod 116a in the piston mechanism 116.
aA and the engaging protrusion 114a provided on the moving base 114
And the push portion 1 of the piston rod 116a.
The spacing between 16aA and the engaging protrusion 114a of the moving base 114 is separated by β. Therefore, when the moving base 110 is moved by β, the piston mechanism 116 moves by β following the moving base 110, but the moving base 114 is
Since it is attached to the moving base 110 via the tension spring 117 and the linear guide 115, the moving base 11
It does not follow the movement of 0 and keeps its position. As a result of such movement, the push portion 116aA of the piston rod 116a and the engaging convex portion 114a of the moving base portion 114 come into contact with each other, and at the same time, the pull-out pin 94 of the magnetic head 91 moved by β by the movement base 110 and the movement thereof. The fall prevention portion 113, which is not affected by the movement of β of the base 110, is engaged. Therefore, the ring portion 7 can be sandwiched between the tip end surface 91a of the magnetic head 91 and the drop-out preventing portion 113, and the ring portion 7 does not come off from the pull-out pin 94 during the further pulling out of the wire heald B. Further, even if an unexpected situation occurs in the magnetic head 91 and the magnetic force is lost, the ring portion 7 will not come off from the pull-out pin 94.

In this state, the piston rod 116
By projecting a and moving the moving base 114 forward in the pull-out direction, the engagement between the drop-out preventing portion 113 and the pull-out pin 94 can be released. Also, the piston rod 1
By retracting 16a, the moving base portion 114 is retracted by the spring force of the tension spring 117, and the fall prevention portion 1
13 can be returned to its original position.

Further, the fall prevention mechanism 112 is provided with a positioning portion 120, and this positioning portion 120 is the lowermost wire heald B held by the floating rod 16.
When pulling out the pull-out pin 94,
It is used to keep the stop position of 3 always constant with respect to the pull-out pin 94. The positioning unit 120 is a movable base unit 1.
The stop pin 121 is attached to the shaft 14, and the amount of protrusion can be finely adjusted by a screw means, and the stopper rod 122 protruding from the front end of the base 12. Therefore, by urging the moving base 114 by the tension spring 117 and causing the stop pin 121 and the stopper rod 122 to collide with each other, the pull-out pin 94 and the drop-out preventing portion 113 are separated before the wire head B is pulled out by the magnetic head 91. The separation distance can always be kept constant.

Next, a method of drawing out the wire heald B will be described based on the configuration of the wire-held drawing-out device 90 described above.

First, as shown in FIG. 15, the moving base 1
Piston mechanism (second drive means) 93 fixed to 10
Is driven to cause the piston rod 93a to project upward by a predetermined amount, thereby raising the magnetic head 91. As a result, as shown in FIG. 13, the pull-out pin 94 is inserted into the guide hole 8 of the lowermost ring portion 7 and also inserted into the cutout portion 16b of the floating rod 16.
At this time, the coil 1 arranged around the magnetic head 91
The wire portion 30 is energized and the ring portion 7 is magnetically attracted to the tip surface 91a of the magnetic head 91, whereby the wire heald B is ready for extraction.

In this state, as shown in FIGS. 18 and 19, the servomotor 92d of the drive mechanism 92c is driven,
By rotating the screw shaft 92cA in a predetermined direction, the moving base 110 is advanced by β. As a result, the lowermost wire heald B is pulled out by β by the extraction pin 94, and at the same time, the lowermost ring part 7 is pulled out by the extraction pin 94.
It is hooked and held on the magnetic head 91 by the engagement of the drop prevention portion 113 with the drop prevention portion 113, and the drop of the wire heald B from the magnetic head 91 during pulling out is appropriately prevented. At this time, the push portion 116aA of the piston rod 116a comes into contact with the engaging convex portion 114a of the moving base portion 114 to prepare for the movement of the fall prevention portion 113.

After that, the drive mechanism 92c shown in FIG. 1 is operated to cooperate with the pull-out pin 94 and the drop-off preventing portion 113,
In addition, by the magnetic attraction force of the magnetic head 91, the moving base 110 is moved forward as shown in FIG. 20 while the lowermost ring portion 7 is hooked and held by the magnetic head 91. Then, as shown in FIG. 21, after the lowermost wire heald B is completely extracted from the stocker 10, the wire healds B shown in FIGS.
As shown in FIG. 11, the piston rod 116 a is projected, and the movable base 114 is advanced in the pull-out direction against the spring force of the tension spring 117, so that the drop-prevention portion 113 and the pull-out pin 9 a.
Release the engagement with 4. At this time, by switching the current to the coil 130 arranged around the magnetic head 91 to the demagnetizing AC attenuation current, the residual magnetism of the wire-held B magnetized by the magnetic head 91 at the time of magnetic attraction is eliminated and the magnetic head 91 is removed. Can release the ring portion 7 of the wire-held B.

Then, as shown in FIG. 24, the lowermost wire heald B is delivered to the standing block 141 of the heald delivery mechanism 140 which will be described later. Then, the piston mechanism 93
25 to lower the piston rod 93a,
As shown in FIG. 6, the moving base 110 is retracted along the guide rail 92a, so that the pull-out pin 94 of the magnetic head 91 is returned to just below the notch 16b of the floating rod 16.

FIG. 26 shows a wire-held B drawing device 131 according to another embodiment. The drawing device 131 has a straight-moving unit 132 composed of a rodless air cylinder. This straight unit 132
A sliding table 133 is disposed on the sliding table 133, and an air cylinder 134 is fixed on the sliding table 133, and the moving base 110 is moved back and forth by β by this air cylinder (see FIG. 27). In addition, a stopper rod 137 is provided on the sliding table 133, and the straight advance unit 13 is provided.
A stopper portion 135 for forcibly stopping the moving base 110 is provided at the front end of 2, and the stopper rod 137 and the stopper portion 135 are arranged to face each other.

Stop pins 136 having different lengths are attached to the stopper portion 135, and each stop pin 136 is attached.
And the stopper rod 137 collide,
The sliding table 133 can be stopped at any position. Since the stop portion 135 is configured as a revolver type that can be rotated and fixed at an arbitrary position, various stop pins for colliding with the stopper rod 137 can be obtained by rotating the stop portion 135 at appropriate times. 136 can be arbitrarily selected. As described above, by arbitrarily selecting the stop pins 136 having different lengths, in order to correspond to various wire healds B having different total lengths, the sliding table 1 by the rectilinear unit 132 is used.
The movement distance of 33 can be arbitrarily selected. Also,
It goes without saying that the number of selections of the moving distance of the sliding table 133 can be changed according to the number of the stop pins 136.

Here, as shown in FIG. 21, the stocker 1
A heald delivery mechanism 140 is disposed in front of 0, and the heald delivery mechanism 140 has a standing block 141 that rotates 90 degrees around a support shaft (not shown) located at the substantially center. At both ends of the standing block 141, the first and second magnetic heads 1 for fixing a heald, which constitute an electromagnet, are provided.
42, 143 are provided, and these magnetic heads 142, 1
43 is exposed toward the transport path of the wire heald B, and is separated by a distance corresponding to the entire length of the wire heald B. A degaussing head 144 is arranged between the first magnetic head 142 and the second magnetic head 143, and the degaussing head 144 is provided adjacent to the first magnetic head 142 on the heald carrying-in side.

Therefore, when the lowermost wire heald B is pulled out from the stocker 10 using the pull-out pin 94, the wire heald B is magnetically attracted to the first magnetic head 142 of the standing block 141 as shown in FIG. , A stable extraction of the wire-held B is achieved. At this time, a residual magnetism is generated in the wire heald B by the magnetic force of the first magnetic head 142, and therefore a degaussing AC current is passed through a coil (not shown) arranged around the degaussing head 144, so that the first magnetic head The wire-held B can be pulled out while eliminating the residual magnetism generated in the wire-held B by 142. Then, when the wire heald B is completely pulled out and both ring portions 7 of the wire heald B are arranged below the first and second magnetic heads 142 and 143, the pulling-out of the wire heald B is stopped.

Then, as shown in FIG. 22, the engagement between the drop-out preventing portion 113 and the pull-out pin 94 is released, and the coil 13 is released.
By switching the current to 0 to the demagnetizing AC damping current,
Demagnetizes the ring portion 7 magnetized by the magnetic head 91,
The ring portion 7 is released from the magnetic head 91. And
In the standing block 141, by energizing a coil (not shown) arranged around the second magnetic head 143, the ring portion 7 of the wire-held B is moved to the second magnetic head 14 by the energization.
3 is magnetically attracted to the standing block 141 at the same time.
The wire-held B at the bottom is delivered to. After that, the wire heald B delivered to the standing block 141 stands upright by rotating the standing block 141 by 90 degrees, and is sent to a threading mechanism (not shown) by a predetermined conveying means. At this time, the residual magnetism of the wire-held B can be removed by passing a degaussing AC attenuation current through the coils of the degaussing head 144, the first magnetic head 142, and the second magnetic head 143. By removing the residual magnetism in this way, it is possible to eliminate the phenomenon in which the wire healds B are close to each other in the weaving process in the automatic loom.

As shown in FIGS. 1, 8 and 28, the wire-held stocker 10 is provided with a wire-held separating mechanism 40 for further securely pulling out the wire-held B at the extreme end (in this case, the “lowermost stage”). The wire-held separating mechanism 40 is provided on the front side of the stocker 10 and has a push-up pawl 41 as a push-back pawl arranged below the front floating rod 16 as shown in FIGS. 29 and 30. The push-up claws 41 are formed in an L shape and form a pair on the left and right. Each push-up claw 41 extends in the horizontal direction and is inserted into the floating rod 16 on the front side to engage with the lowermost ring portion 7 held at that position, and the claw 42. The supporting portion 43 extends downward from the base end of the claw portion 42 for supporting.

By separating the tip portions (free end portions) of the left and right claws 42, 42 from each other, a gap 44 is formed between the claws 42, 42. This gap 44 is a rod part of the wire heald B. The diameter is slightly larger than the diameter of 5. Further, a taper surface 42a is formed at the tip of the claw portion 42 and is inclined obliquely downward toward the tip. When the push-up claw 41 moves up, the tip of the claw portion 42 is inserted into the claw engaging recess 45 formed in the lower end surface 16a of the floating rod 16 on the front side. A tapered surface 45a that matches the tapered surface 42a of the claw portion 42 is formed on the (see FIG. 14). In addition,
As shown in FIG. 28, when the push-up claw 41 descends, it is necessary to completely bury the claw portion 42 in the base 12. Therefore, a claw accommodating concave portion 54 is formed on the upper surface of the base 12 on the distal end side. . However, when the rear floating rod 16 is not moved up and down by the push-up pawl 41, the rear floating rod 16 does not necessarily need to be provided with the pawl engaging recess 45.

Further, as shown in FIG. 28, the wire-held separating mechanism 40 has a base portion 46 for vertically fixing the L-shaped push-up claws 41, and the base portion 46 is arranged below the base 12. ing. A concave portion 47 for seating a spring is formed on an upper surface 46 a of the base portion 46, and the concave portion 4 is formed on the base portion 46.
A pin insertion hole 48 is formed so as to vertically penetrate the base 46 so as to sandwich 7 (see FIG. 29). Also, the base 4
The upper surface 46a of 6 and the bottom surface 12b of the base 12 are recessed 47
It is connected via a compression spring 50 that is seated inside, and this compression spring 50 urges the base portion 46 away from the base 12.

Therefore, two pins 51 are projected downward on the bottom surface 12a of the base 12, the pins 51 are inserted into the pin insertion holes 48 of the base portion 46, and a snap ring or the like is formed at the lower end of the pin 51. By providing the stopper portion 51a, the base portion 46 can be moved up and down in the extending direction of the pin 51 under the elasticity of the spring 50. The base 46
A pair of upper and lower tongue pieces 52 that engage with an operating piece 64 to be described later are provided on the projection (see FIG. 28). The upper tongue piece 52 is pushed up by the tip of the operating piece 64, and the lower side tongue piece 52 is pushed down by the tip of the operating piece 64 when the base 46 is not smoothly lowered by the compression spring 50.

Here, as shown in FIG. 8, the base portion 46 is moved in the vertical direction (held stacking direction) by the driving means 60. The drive means 60 is provided on the base 12 of the housing 11.
An air cylinder 62 fixed to a support base 61 for supporting the air cylinder 62, a cylinder rod 63 that reciprocates vertically with a predetermined stroke with respect to the air cylinder 62, and is provided with a rotation stop, and a cylinder rod 63. And an operating piece 64 that is fixed to the tip of the tongue piece 52 of the base portion 46 and is engaged with the tongue piece 52 of the base portion 46. Therefore, the base portion 46 can be moved up and down by a predetermined amount according to the stroke amount of the cylinder rod 63. When the tip of the operating piece 64 is inserted between the tongue pieces 52, the operating piece 64 is inserted between the tongue pieces 52.
The stroke amount of the cylinder rod 63 is not the rising amount of the base portion 46 due to the play. However, by directly driving the push-up claw 41 with the air cylinder 62, it is not necessary to employ the base portion 46 or the operating piece 64, and it is also necessary to provide a play between the tongue pieces 52 and the tip of the operating piece 64. Disappear.

Next, the wire-held separation mechanism 40 described above.
The wire-held separation method according to the above will be described.

As shown in FIGS. 31 and 32, when pulling out the lowermost wire heald B, first, the pullout pin 94 is inserted into the cutout portion 16b of the front floating rod 16 and, at the same time, the lowermost wire heald B is pulled out.
The ring portion 7 is magnetically attracted to the magnetic head 91. At this time, since the claw portion 42 of the push-up claw 41 is completely buried in the claw housing recess 54, it does not interfere with the withdrawal of the ring portion 7. After that, pulling out the lowermost ring portion 7 slightly with the pull-out pin 94, and
The ring portion 7 in the lowermost stage with respect to the ring portion 7 in the second stage (next stage)
By shifting and exposing the ring portion 7 of the next stage,
Prepare for separation of the wire heald B at the bottom (see FIG. 30). At this time, the magnetic head 91 is moved horizontally until the pull-out pin 94 comes under the drop-out prevention portion 113 that has been waiting in front of the heald pull-out port 9, so that the drop-out prevention portion 113 and the magnetic head 91 cooperate with each other. This prevents the ring portion 7 of the wire heald B at the lowermost stage from coming off.

Then, as shown in FIGS. 33 and 34,
By driving the air cylinder 62 to raise the operating piece 64, the upper tongue piece 52 is pushed up by the tip of the operating piece 64, so that the base portion 4 is resisted against the spring force of the compression spring 50.
6 increases by a predetermined amount. At this time, as the push-up claw 41 rises, the rod portion 5 of the wire heald B at the lowermost stage is moved to the claw portion 4.
Since it passes through the gap 44 between the two, the wire heald B at the lowermost stage keeps its position without being affected by the lifting of the push-up claw 41. Then, the claw portion 42 is inserted into the claw engagement concave portion 45 of the front side floating rod 16 to combine the tapered surfaces 42a and 45a, and then pushes up the front side floating rod 16 from below.

Further, utilizing the upper surface 42b of the claw portion 42,
The exposed ring portion 7 of the next stage is pushed up from below. As a result, the stacked ring portion 7 inserted into the floating rod 16 and held at that position and the front floating rod 16 can be lifted at the same time. Only wire-held B of other wire-held B
Separated from Then, by the cooperation of the drop-out preventing portion 113 and the magnetic head 91, the lowermost wire heald B can be smoothly pulled out while the lowermost ring portion 7 is reliably hooked to the pullout pin 94. After the wire heald B at the lowermost stage is completely pulled out, the air cylinder 62 is driven to lower the operating piece 64, so that the base portion 46 is moved by the spring force of the compression spring 50.
Return to the position and prepare for the next drawing operation.

Next, as shown in FIGS. 35 and 36, the wire-held stocker 10 is provided with a wire-held separating mechanism 70 for further reliably pulling out the wire-held B at the extreme end (in this case, the "lowermost stage"). The wire-held separating mechanism 70 is provided on the rear side of the stocker 10 and has a push-up member 71 as a block-like push-back member that is disposed below the floating rod 16 on the rear side and extends in the vertical direction. The push-up member 71 is inserted from below into the rectangular opening 72 formed in the base 12 below the floating rod 16 on the rear side, and is erected on the base 73 arranged below the base 12. Has been. The block-shaped pushing-up member 71
May be formed in a claw shape or a hollow shape for weight reduction.

A recess 74 for seating a spring is formed on the upper surface 73a of the base 73, and a pin insertion hole 75 is formed in the base 73 so as to vertically penetrate the base 73 so as to sandwich the recess 74. Further, the upper surface 73a of the base portion 73 and the bottom surface 12b of the base 12 are connected via a compression spring 76 seated in the recess 74, and the compression spring 76 moves in a direction in which the base portion 73 is separated from the base 12. I am urging. Therefore, the two pins 7 are provided on the bottom surface 12a of the base 12.
7 is projected downward, this pin 77 is inserted into the pin insertion hole 75 of the base 73, and a stopper portion 77a made of a snap ring or the like is provided at the lower end of the pin 77, so that the elasticity of the spring 76 allows The base portion 7 extends in the extending direction of the pin 77.
3 can be moved up and down. The pin 77 is inserted into the pin insertion hole 75 without play.

Here, the base 73 is moved in the vertical direction (held stacking direction) by the driving means 80, and the driving means 80
Is arranged directly below the base portion 73. This drive means 80
Is an air cylinder 81 fixed to a part of a support base 61 for supporting the base 12 of the housing 11 via a bracket or the like, and a cylinder that reciprocates vertically with a predetermined stroke with respect to the air cylinder 81. Rod 8
2 is provided. The tip of this cylinder rod 82 is
The opening 8 formed in the support base 61 below the base 73
The bottom surface of the base portion 73 is faced by being inserted into the base portion 3 from below. Therefore, the cylinder rod 82 is projected from the opening 83, and the base portion 73 is pushed up by the tip of the cylinder rod 82, whereby the base portion 73 and the pushing-up member 71 are raised. Then, by lowering the cylinder rod 82 and burying the cylinder rod 82 in the opening 83, the base portion 73 and the pushing-up member 71 are lowered by the urging force of the spring 76. However, the air cylinder 81 is the base 1
2 and fix the lifting member 7 with this air cylinder 81.
By directly driving 1, it is not necessary to employ the base 73, the spring 76, or the like.

As shown in FIGS. 36 and 37, a ring lead-in portion 84 cut horizontally is formed at the rear portion of the lower end surface 16a of the rear floating rod 16.
The ring lead-in portion 84 has a cutting depth P slightly larger than the height H of one ring portion 7. Further, a projection 86 that projects in the axial direction is formed at the front portion of the lower end surface 16a of the rear floating rod 16, and the lower end surface 16a on the side of the projection 86 and the lower end surface 16a on the side of the ring retracting portion 84 are formed. Are connected via a tapered surface 85. In addition, only the lowermost ring portion 7 is connected to the ring retracting portion 8
In order to be surely inserted into the inside of the ring 4, the cutting depth P is formed to be smaller than the height 1.5H of 1.5 ring portions 7.

Next, the wire-held separation mechanism 70 described above.
The wire-held separation method according to the above will be described.

As shown in FIGS. 31 and 32, when pulling out the lowermost wire heald B, first, the pullout pin 94 is inserted into the notch 16b of the floating rod 16 on the front side, and at the same time, the lowermost wire heald B is pulled out.
The ring portion 7 on the front side is magnetically attracted to the magnetic head 91. At this time, since the claw portion 42 of the push-up claw 41 is completely buried in the claw housing recess 54, it does not interfere with the withdrawal of the front ring portion 7. After that, by pulling out the front ring portion 7 slightly with the pull-out pin 94, the lowermost ring portion 7 is displaced relative to the second (next stage) ring portion 7 from the bottom, and the rear ring portion of the next stage is moved. By exposing the portion 7, preparation for separating the wire heald B in the lowermost stage is completed. At this time, as shown in FIG. 38 and FIG. 39, the rear end of the rear ring portion 7 in the lowermost stage passes through the opening 72 of the base 12 and enters the ring retracting portion 84 of the rear floating rod 16. Since it is guided, the ring portion 7 does not collide with the floating rod 16 and the floating rod 16 does not float. The protrusion 86 of the floating rod 16 on the rear side is still located inside the ring portion 7 at the lowermost stage.

Then, as shown in FIG. 40, the air cylinder 81 is driven to push up the base portion 73 with the tip of the cylinder rod 82, so that the base portion 73 rises, and the push-up member 71 also moves backward. Ascends toward the ring portion 7 on the side. As a result, the rear floating rod 1
While simultaneously pushing up the ring portion 7 of the next stage inserted in 6 and held at that position and the lower end surface 16a on the ring retracting portion 84 side by the top surface as the tip end portion of the pushing-up member 71, Protrusion 86 inserted into the ring portion 7 of the
Can also be lifted. Therefore, when the protrusion 86 is separated from the base 12, the engagement between the lowermost ring portion 7 and the floating rod 16 on the rear side is completely released. Thereafter, by further advancing the pull-out pin 94, the lowermost wire heald B is smoothly pulled out without the rear floating rod 16 and the lowermost ring portion 7 colliding with each other. After completion of pulling out the wire heald B in this way, the cylinder rod 82 is lowered and the tip of the cylinder rod 82 is buried in the opening 83, whereby the base portion 73 and the pushing-up member 71 are lowered by the urging force of the spring 76.

Therefore, when the lowermost wire heald B is pulled out, the floating rod 16 on the rear side does not collide with the ring portion 7 on the lowermost stage.
The lower end surface 16a of the wire and the wire heald B are prevented from rubbing and wearing. Further, when the wire heald B is pulled out at an extremely high speed, the floating rod 16
Since it is possible to avoid repeated collisions between the wire-held B and the wire-held B, an excessive load is not applied to the wire-held B, the wire-held B is not deformed, and the life of the wire-held B itself can be extended.

The wire-held drawing device and drawing method according to the present invention are not limited to the above-described embodiments. For example, although not shown, a large number of ring portions 7 of the wire heald B are attached to a pair of upper and lower floating rods that are spring-biased with respect to a base extending in the vertical direction and extend horizontally, and are suspended in the vertical direction. The drawing device and the drawing method of the present invention can be applied to a heald group in which the wire healds B are stacked in the horizontal direction.

For example, the upper ring portion 7 of the wire heald B at the outermost end (in this case, the "frontmost end") is magnetically attracted to the magnetic head, and the magnetic head is slightly raised, so that the wire heald B at the frontmost end is removed. It is hooked on the drawer pin and rises slightly. As a result, the upper ring portion 7 of the second (second from the frontmost) wire heald B is
On the other hand, the upper ring portion 7 of the frontmost wire heald B is slightly displaced, and the next upper ring portion 7 is exposed. After that, the claw portion of the push-back claw as shown in FIG. 29 is moved in the horizontal direction (held stacking direction) from the outside toward the next ring portion 7.
