An air guide 8'is fixedly installed between the guide and the air passage formed in the inner surface of the guide piece 8'A, and a yarn discharge slit extending from the inlet to the outlet is communicated from the lower end. Immediately before the outlet of the air guide 8 ', a reed 12' is disposed so as to be movable in a direction orthogonal to the direction of the outlet, and can be intermittently moved in the direction of the arrow by a gap 12'a between the reeds.
The gap 12'a between the reeds is sequentially moved to a position facing the outlet of the air guide 8 '.

A plurality of supply rods 1 are provided on the left side of the support disk.
3'is supported so as to be aligned in the moving direction of the reed 12 'and in a direction orthogonal to this moving direction, and a large number of healds 15' are suspended and suspended on each supply rod 13 '. . An air cylinder 17 'is arranged at a position facing the guide body 16' in the direction of the supply rod 13 '. Support 14
Is movable in the direction orthogonal to the supply rod 13 ', and one of the supply rods 13' supporting the heddle 15 'is arranged at a position facing the guide body 16'.

The heddle 1 of the supply rod 13 'in this facing position
The contact member 17'b is pressed against 5'by the projection of the drive rod 17'a of the air cylinder 17 '. As a result, the heddle 15 'is inserted into the guide portion of the guide body 16', and the leading heddle 15 'is pressed around the supporting discs 2', 3 ', 4'. The leading heald 15 'to be pressed is the holding recess 2'.
a, 3'a, 4'a is pushed into and is attracted by the magnet 6 on the bottom surface, and one heald 15 'is used for each supporting disc 2', 3 '.
It is adsorbed and held in an upright state over ‘4’.

The holding recesses 2'a, 3'a, 4'a are sequentially switched to six 60 ° divided positions by the 60 ° intermittent rotation of the drive shaft 1 '. An air cylinder 19 'is arranged diagonally upward on the front side of the inlet of the air guide 8', and an air nozzle 20 'is fixed to the tip of a drive rod 19'a thereof. A guide rail 21 is arranged parallel to the drive rod 19'a, and a slider 22 'is provided.

[Problems to be Solved by the Invention] Japanese Patent Publication No. 4-78739
The drawing device disclosed in Japanese Patent No. 1 has detailed the technique of passing the warp between the heddle holes and the reed wing by an air jet, but the example of the technique is an experimental one and is actually used as a practical machine. Has the following problems to be solved.

(1) In order to pass the warp through the heddle hole, it is necessary to align the heddle hole with the air ejection port of the air nozzle. The heddle is gripped by the turntables located above and below, but the position is not fixed near the air nozzle. If the heddle is new, there is no problem, but the heddle that has been repeatedly used is not straight, but there is a bent one, and the heddle hole and the air nozzle injection port do not match and threading error occurs.

(2) In order to pass the warp through the heddle, it is necessary to dispose the warp in the vicinity of the heddle hole. This product has an injection port and a thread hooking groove to stabilize the thread. However, the method of inserting the warp threads into the thread hooking groove one by one has not been solved. Although one yarn is separated from the yarn bundle by a leaching device (yarn separating device), spun yarn generally has fluffs, and the yarn bundle and the yarn to be separated are stuck together and cannot be reliably separated. Therefore, in the yarn hooking groove of the air nozzle. If you do not enter it, you will get a threading mistake.

In order to avoid the adverse effect of the fluff as much as possible, it is effective to apply a tension to the warp, but it is difficult to use the detachable gripping means. Therefore, the warp is generally fixed by the upper and lower gripping means and cut by a cutter in general. At the time of cutting, the elastic force of the warp may cause the yarn to vibrate and be disengaged from the yarn hooking groove.

(3) The threaded heddle is carried to the installation waiting position by the turning of the tongue table, and is further installed in the storage position of the heddle bar. Therefore, the warp is bent, and due to the tension, the heddle attached to the heddle bar is pulled back, which adversely affects the next threading.

The present invention has been made in view of the above problems of the prior art. For the purpose of the invention, Japanese Examined Patent Publication No. 4-78739 was studied at a test site and a theoretically possible technique was developed. The invention is to solve the problems one by one and complete a reliable practical machine.

[0017]

In order to achieve the above object, the present invention has a heddle beam of a heddle, which is mounted on a heddle support disk and sequentially indexed from a heddle storage magazine, and wound around a warp beam. In a drawing device adapted to insert warps one by one, and then insert them into a reed, and sequentially store the healds through which the warps have passed, a device for separating one warp Two warp yarns of the warp yarns are provided on both sides of the rotation shaft so as to be swingable and movable in the axial direction, and the warp yarns for swinging and restraining the guide pipes to release the restraint of the guide yarns. And a pair of first claws that can be opened and closed to move the released warp inward between the two guide tubes and a pair of openable and claws of the warp provided with driving means for expanding the gap between the warp and the open warp. Key-shaped claw that temporarily restricts the inner position and integrally with this A second pawl provided with a pivotable sickle-shaped pawl for moving the warp yarn further inward, a drive means for opening and closing the first pawl, and a drive means for pivoting the second pawl are provided, The present invention further comprises a warp separating device including a rotated feed screw member for further feeding the separated warp to the complete separating position.

Further, a drawing device for carrying the warps separated from the warp warp one by one to the front of the heddle hole of the heddle attached to the swivel support member and indexed by the air nozzle member, and passing the warp through the heddle hole by the jet air. In the above, the separated yarn is sucked by the nozzle head by suction while being held, and the cut end of the drawn yarn is held and air is jetted in synchronization with the air jet from the nozzle head to release the holding of the yarn end. The end holding means is provided.

In a drawing device in which warp yarns separated from warp warp yarns are respectively attached to a swivel support member and carried to the front of the heddle hole of a heddle indexed by an air nozzle member, and the warp yarns are passed through the heddle hole by jet air. The heddle indexed at the threading position is provided with a positioning claw that can advance and retreat prior to threading, for correcting the position of the heddle hole.

The warp yarns separated from the warp warp yarns are drawn out one by one by an advancing and retracting air nozzle member, and are carried to the front face of the heddle hole of the heddle attached to the support disk member and carried to the heddle hole and the reed by the jet air. In a drawing device for threading, a thread lifting member that is capable of lifting and laterally moving the lower side of a thread that is hooked by a nozzle head and that is arranged substantially parallel to a heddle storage bar and that aligns the lifted thread A cradle is included, and a yarn holding means for pulling the passed yarn in a direction perpendicular to the heddle storage bar is provided.

Further, a crab-shaped lever capable of turning is provided to pass the lower side of the pulled-out thread to the scoop-up thread lifting member.

[0022]

According to the first aspect of the present invention, the twill yarn is opened by turning the guide tube at a predetermined angle and one warp yarn is released from the restraint. Along with the closing operation of the first pawl, the guide tube moves forward to push the warp under restraint to form a gap with the open warp. In the meantime, the key-shaped pawl of the second pawl stops the inward movement so that the warp may vibrate when it is released so that the warp thread does not enter and the feed screw is not caught. First in this gap
The nail penetrates and pushes the warp inward on the slope inside the nail. At the same time, the second pawl turns to retract the key-shaped pawl and the sickle-shaped pawl invades to move the open warp further inward, hook it on the tip of the rotating feed screw and move it to the root to separate it. . The two types of claws move the open thread so that the separation is complete without being returned by the fluff.

According to a second aspect of the present invention, the warp drawn by the nozzle head is sucked by the suction nozzle, the cut warp end is held and stretched with a predetermined tension, and the warp on the front face of the heddle hole is slackened on the front face of the nozzle. Position it. Then, in synchronization with the ejection of the pressure air from the nozzle, the pressure air is ejected from the suction nozzle to forcibly separate the yarn end. Therefore, the movement of the warp yarns is not disturbed by the fluff or the like, and the yarns are smoothly threaded through the heddle holes.

According to the third aspect of the present invention, the positioning claw is positioned by sandwiching the heddle mounted on the support disk before the threading. For this reason, the position of the heddle hole which has been displaced due to the deformation is corrected, and the threading can be reliably performed.

According to the fourth and fifth aspects of the present invention, the warp picked up by the crab-shaped lever is further lifted by the thread lifting plate above the thread receiving base and moved laterally to form a thread line substantially perpendicular to the heddle storage bar. Therefore, when the threaded heddle is stored, it is stored in a stable state without being pulled back by the elastic force of the thread.

In parallel with the above operation, the heddle 20 is mounted on the support disk 303. That is, as shown in FIG. 3, the heald-opening claws 602 and 603 are advanced in the arrow direction, and the tip 6 of the claw 603 is moved.
03a penetrates between the first heald and the second heald at the forefront, and the first heald 20 extends between the claws 602 and 603 to widen the lower space. Next, an opening claw (not shown) swivels, and the upper part is opened at the same interval and becomes vertical. While the fixed side claw 606 and the moving side claw 607 that have been retracted simultaneously rotate and open, the moving side claw 607 enters and the shaft 60
It moves in four directions and holds one heald 20 with the fixed side claw 606. The magnet 3 in the notch 303a of the support disk 303 is moved to the support disk side with the upper and lower sides of the heddle being clamped.
After being sucked by 04, the grip claws are swung and retracted. In this way, the heddle is sequentially held in each notch 303a on the circumference, and one is indexed at the threading position.

The rotary actuator 704 of the heald positioning device 7 is actuated to move the rack shaft 702 as shown in FIG.
Is moved forward, and the pair of positioning claws 703 move the supporting disc 30
The position of the heddle hole 20a that is displaced due to deformation such as sandwiching the heddle 20 mounted on the head 3 is corrected. The swing arm 402 retracted rearward from the warp line fixed to the upper clamp 12a and the lower clamp 12b is swung forward as shown in FIG.
The warp yarn T1 separated and positioned on the tension yarn T1b is hooked by the nozzle head 404 and conveyed to the front surface of the heddle hole 20a of the heddle 20 of the notch 303a in which the support disk 303 is positioned.

When the swinging movement of the swing arm 402 starts, the cutter 31 acts to cut the warp yarn T1 of the tension line T1b. The cut warp T1 ends are suction nozzles 503, 50.
7 is sucked and held by the rotary actuator 33, and the rotary actuator 33 is actuated to rotate the curved ball claw 34 to receive the yarn. For this reason, the warp pulled by the swing arm does not sag and the predetermined tension is maintained. The yarn end of the warp yarn T1 fixed to the remaining clamp 12a after cutting is sucked into the suction nozzle 32.

Further, as the swing arm 402 advances, the claw-shaped lever 801 (FIG. 2) is swung by the operation of the actuator 803 to scoop up the lower side of the warp. When the actuator 806 is operated, the thread lifting plate 807 is
Is lifted and the scooped warp yarn T1 is further lifted. The yarn lifting plate 807 is moved laterally by the operation of the air actuator 808 and is positioned on the yarn receiving base 804.
Next, the air actuators 806 and 808 are operated to lower the yarn lifting plate 807 and move it to the original position. As a result, the warp yarn T1 is placed on the yarn receiving base 804 as shown in FIG.

When the crab-shaped lever 801 picks up the thread, the nozzle 403 of the nozzle head 404 of the swing arm 402
Also, pressure air is ejected from the suction nozzle 508, the ends sucked by the suction nozzles 502 and 507 are blown away, and the warp yarn T1 is sent into the heddle hole 20a.
Of the warp T1 passes through the air guide groove 25a of the reed 16 together with the pressure air to pass through the reed between the reeds of the reed 16, and the tip of the warp is sucked into the suction nozzle 28 through the air guide plate 27 so that the warp is passed through both the heddle and the reed. It

The hook 902 of the heddle storage device 9 (FIG. 3) standing by at the mounting standby position is swung by the link 905, and the heddle bar holes 20 above and below the heddle 20 after threading have been completed.
b is removed from the support disk 303 by hooking it, and the belt 903 is removed.
Is driven to position the heddle in front of a predetermined heddle storage bar 904 of the heddle storage device, and the link is operated to move the heddle 20 from the hook 902 and store it. The hook 902 retracts.
Along with this, the reed 16 is also moved by one reed wing, and the thread thus threaded is arranged as shown in FIG. Support disk notch 303a
The heddle attached to the helicopter is rotationally positioned by 1/6 of the support disk 303, and the warp thread is sequentially threaded to the heddle reed.

Since the present invention is constructed as described above, the present invention has the following effects. As for claim 1, it has not been sufficiently researched to separate one yarn from the warp warp with the drawing device of the prior art, and the separation could not be performed efficiently. Can be separated into

According to a second aspect of the present invention, when the warp yarn is pulled out by hooking it with the nozzle head of the second yarn moving device, the warp yarn and the yarn end in the middle of pulling out are surely sucked and grasped, so that the vibration due to the yarn elastic force during cutting is suppressed before the heddle hole. The necessary tension can be given to the warp threads, and the pressure air is jetted from the nozzle head at the same time as the pressure air is jetted from the suction nozzle to open the thread end without catching it, so the thread can be inserted into the heddle hole securely. Done.

In the third aspect, the heddle is deformed as the frequency of use increases. For this reason, the heddle hole is not necessarily located at the threading position while being held by the support disk.
Since this deviation is corrected by the positioning claw before the ejection of the pressure air, the nozzle and the heddle hole can be aligned with each other, and reliable threading without mistakes can be performed.

According to the fourth and fifth aspects, the warp thread placed on the thread receiving base provided with serrations so as not to slip by the thread lifting plate is substantially perpendicular to the heddle storage bar at the retracted position of the heald after threading. Therefore, stable storage can be performed without pulling back the storage heddle due to the thread tension.
