Problems to be solved by the invention Therefore, the degree of completion of the knotting is uneven, and not only is it difficult for inexperienced workers to quickly complete the knotting work, but it is also easy to cause defective knotting. Furthermore, the efficiency of the thread winding operation is extremely poor, and when winding a large number of spools, a large amount of time is required, and the supply cannot be kept in time. Therefore, in order to wind a large amount of thread in a short period of time, it is necessary to have a plurality of turntable devices and to have a corresponding number of workers.

The end of the remaining thread A wound around the spool 1 and pulled out from the shuttle 2 is tied with the end of the supply thread B supplied from a creel stand (not shown). The thread B is wound around the spool by rotating the thread, and the shuttle 2 is mechanically sent to the shuttle set position, and when the thread winding is completed, the shuttle is removed and another shuttle is sent in, making continuous work possible. All processes are automated. The configuration of the device will be explained based on FIGS. 1 and 2. Below the shuttle set position, a conveyance path 5 is provided which is perpendicular to the shuttle set direction and passes directly below the shuttle set position. The conveyance path 5 is provided with free rollers 5a, 5a, . A spool 1 for winding thread is stored in a shuttle 2, and the shuttle 2 is further arranged vertically in a storage box 6. Place it on top so that it is hung. The storage box 6 is open at the top and bottom, and a rack gear 6a is attached to the center of the lower surface in the longitudinal direction and meshes with the pinion gear 5b. The pinion gear 5b is intermittently rotated by a motor 5c via a chain,
By this rotation, the storage box 5 can be moved one pitch at a time, corresponding to between the shuttles that are stored in alignment. A push-up member 7 that is raised and lowered by a cylinder 7a is provided below the conveyance path 5 directly below the shuttle set position, and the push-up member 7 has a bifurcated fork shape.
At each end there is an insertion groove 7 into which the shuttle 2 is inserted.

One clamping plate 4
a is free from rotation, and the other clamping plate 4'a can be applied with rotational force by a motor 10, rotating the clamping plate 4'a with the shuttle 2 clamped therebetween. Then, the spool 1 in the shuttle 2 can be rotated in the yarn winding direction. The rotating shaft 9c of the holding plate 4'a can move forward and backward in a state where rotation can be transmitted by a combination of a spline and a spline shaft. In addition, the shuttle 2 is in the shuttle set position, and the thread release portion 2a is
is fixed by the fixing mechanism 3, and the thread pulling part 2a
The remaining thread A wound on spool 1 from the tip of
is pulled outward with its end as a free end. The fixing mechanism 3 has a structure in which a fixing hook body 12, which is a fixing member, is engaged and disengaged by a cylinder 11, thereby fixing and releasing the thread pulling portion 2a of the shuttle. Incidentally, the shuttles 2 can be set one by one manually, instead of being set mechanically in succession as in this embodiment. Reference numeral 13 denotes an intermediate holding mechanism that holds the supplied yarn (warp yarn B) supplied from a creel stand (not shown) in the yarn feeding path. This combination prevents the thread from loosening during knotting. The intermediate holding mechanism 13 includes a presser plate 13c that is pressed against the surface of the fixed plate 13b by the cylinder 13a.
The tension mechanism 14 is configured to sandwich the supply yarn B between the fixed plate 13b and the fixed plate 13b, and the tension mechanism 14
is threaded in a V shape by the pulleys 14a, 14'a, 14''a, so that the pulley 14'a is suspended by the supply thread B, and the pulley 14'a is attached. The vertically movable slide member 14b pulls the supply yarn B downward only by its own weight to provide tension at all times, and the cylinder 14
The structure is such that a pulling force can be forcibly applied by pulling down the slide member 14b that is engaged with the pull-down plate 14d at c. Nodule position P
is equipped with a winding drum 16 that is horizontally rotated around a vertical axis of rotation by a motor 15. The winding drum 16
has a boat-shaped tip with a beak-shaped tip protruding in the horizontal direction perpendicular to the rotation axis, and a hook 17a of a hook 17, which will be described later, passes through the bottom of the boat to connect the front (pointed end of the winding drum 16). (The side is called the front and the opposite side is called the back)
An escape path is formed by an escape groove 16a that can protrude into. Further, the winding drum 16 can be rotated to either the left or right, and is always stopped in a fixed position facing the direction in which the hook 17 moves forward and backward. The shape of the winding drum 16 may be such that, as long as the hook 17 can pass through forward, a through hole may be provided in the winding drum 16 to provide an escape route instead of the escape groove 16a as described above. At the rear of the winding drum 16, a hook 17 is provided which moves horizontally forward and backward by a cylinder 18, and a hook 17a is formed upward at the tip of the hook 17. The hooking pawl 17a can pass forward of the winding drum 16 along the relief groove 16a of the winding drum 16 located on the advancing/retreating path. A winding rod 21 is provided in front of the winding drum 16 and is moved in a circular motion about the longitudinal axis of the winding drum 16 and back and forth in the longitudinal direction by a drive unit 20 equipped with a motor 19. The drive unit 20 is installed on a movable table 20a that slides in the front-rear direction of the winding drum 16, and the winding rod 21 rotates around the central axis of the rotary disc 20b. protrudes horizontally. The disc 20b is connected to a motor 19 via gears 19a, 19a, and the rotation of the motor 19 causes the wrapping rod 21 to rotate around the central axis of the rotating disc 20b. On the other hand, a small gear is coaxially fixed on the opposite side of the gear 19a to which the rotating disk 20b is attached, and rotates the cylindrical cam 20c in conjunction with the rotation of the gear 19a. A cam groove is formed on the outer periphery of the cylindrical cam 20c, and the cam groove of the cylindrical cam 20c, which rotates by gear drive, follows the cam follower 20d fixed to the base side and moves together with the movable base 20a. The entire unit 20 moves back and forth. Thereby, the winding rod 21 has a thread passing hole 2 provided at its tip through which the supply thread is inserted.
1a rotates around the longitudinal axis of the winding drum 16 and reciprocates between the side of the winding drum 16 and the front thereof. The supply yarn B pulled out from the tension mechanism 14 is inserted into the threading hole 21a, and its end is held by a supply yarn gripping mechanism 22 for gripping the supply yarn end located below the knotting position P. It is firmly held by. The supply yarn gripping mechanism 22 has a structure in which a pressing plate 22c is pressed against the inner side surface of the frame 22a through a cylinder 22b inside a cross-sectional frame 22a, and the supply yarn B is held by the pressing plate 22c. Attach the end to the frame 22
It is designed to be held by pressing it against a fixed plate that is one side of a. As a result, the supply yarn B, which is supported on both sides by the supply yarn gripping mechanism 22 and the intermediate holding mechanism 13, respectively, and which is inserted into the threading hole 21a between them, has an allowance in the length of the supply yarn in advance. By holding it and pulling it with the tension mechanism 14, it is possible to pull it out, and as the thread passing hole 21a rotates around the winding drum 16, the supplied yarn is pulled out and the thread is pulled out from the winding drum. 16. The supply yarn gripping mechanism 22 is movable between the lower side of the winding drum 16 and the front and lower side of the winding drum by means of cylinders 22d and 22e. At the rear of the winding drum 16, the hook 17 is provided so as to be movable forward and backward as described above.
When the winding drum 16 and the hook 17 are in the rearward state, a certain gap is created between the winding drum 16 and the hook 17, and a cylinder 23 provided above the gap allows for lifting and lowering. However, a chuck mechanism 24 that reciprocates between the upper and lower portions of the gap is provided. The chuck mechanism 24 is provided with a thread pinching portion at its tip consisting of clamping claws 24b, 24b which can be opened and closed by a cylinder 24a. The clamping claws 24b, 24b are in the lowest position so as to be able to grip the free end of the remaining thread A pulled out from the thread pulling section 2a of the shuttle 2 when the clamping claws 24b change from the open/closed state to the closed state. The remaining yarn B can be picked up and pulled upward by the chuck mechanism 24.
Also, on the side of the gap, a cylinder 25 rotates,

First, the shuttles 2, which are arranged and stored in the storage box 6, move intermittently on the conveyance path 5 and sequentially reach the position immediately below the shuttle set position. It is inserted and supported by the insertion grooves 7a, 7a of the rising push-up member 7 and sent to the shuttle set position. The shuttle 2 sent to the shuttle set position is moved to the fixing mechanism 3
The thread pulling part 2a is locked and fixed by the fixed hook 12, and then the clamping plates 4a, 4'a approach from both sides and are clamped by the clamping plates 4a, 4'a. The push-up member 7 now descends and leaves the shuttle. In this way, the shuttle 2 is correctly set at the set position, and the remaining yarn is pulled out from the yarn pulling section 2a. On the other hand, the supply yarn B is held by an intermediate holding mechanism 13 in the middle of the yarn feeding path, and held at the tip by a supply yarn gripping mechanism 22.

Wrap it in the state shown in Figure c. Next, pull the hook 17 from the rear.
is advanced, and the winding drum 16 around which the supply yarn B is wound
The hook 17a is caused to protrude forward of the winding drum 16 by passing through the relief groove 16a. At the same time, the winding rod 21 is moved back until the threading hole 21a at the tip is located near the side of the protruding hook 17a, and then turned once at that position to pull the supply yarn B through the hook 17. It is engaged with the hanging claw 17a (Fig. 7e). Next, when the winding rod 21 is further retreated and the hook 17 is pulled back, the supply yarn B wound around the winding drum 16 moves behind the winding drum 16 inside the relief groove 16a as shown in FIG. 7f. It is pulled out backwards in a loop. Therefore, the chuck mechanism 24 is passed through the loop from above using the cylinder 23 and inserted downward, and the end of the remaining thread A that has been pulled out from the shuttle 2 is pinched with the clamping claws 24b, and then moved upward again. By returning it, the remaining yarn A is picked up and passes upward through the loop. still,
When the chuck mechanism 24 passes downward through the loop of the supply yarn B pulled out to the rear of the winding drum 16, the chuck member 24 has clamping claws 24b, 24b.
By keeping it closed, you can pass through it smoothly. Furthermore, the cylinder 25 rotates the flip-up rod 25a to flip the loop portion upward and remove it from the hook 17a.Finally, the tension mechanism 14 pulls back the supply yarn B, as shown in Fig. 7i.
The knotting process is completed when a knotted part is formed as shown in FIG.
Through this procedure, it is possible to perform the semi-double knot knotting shown in FIGS. 8a and 8b.

る。以後上記工程を繰り返し連続的に行なう。 Although the above explanation has shown the procedure for tying a semi-double knot, the tying device of the present invention is also capable of tying a double knot by simply changing the operating process of the winding rod and the winding drum. The knotting procedure of the double knot method will be explained based on FIGS. 9a and 9b.
When winding the supply yarn B around the winding drum 16, in the semi-double knot method, the winding rod 21 is turned twice and the winding drum 16 is horizontally rotated once, whereas in the case of the double knot method, the winding rod is first rotated. 21 once, then rotate the winding drum 16 once.
The winding rod 21 and the winding drum 16 are then rotated once again in the same manner as described above to perform winding. The change of the knotting method is performed by motor 15.
This can be easily implemented by simply controlling the operation timing of the motor 19. Note that the subsequent steps are completely the same as those for the semi-double knot method, so they will be omitted. By this procedure, the double knot knotting shown in FIGS. 10a and 10b can be performed. When the knotting operation is completed as described above, the thread cutting heated blade 26 comes into contact with the excess yarn that has been pulled from the knotting section by the chuck mechanism 24 and the supply yarn gripping mechanism 22 near the knotting section, and At the same time, the holding claws 24b, 24b of the chuck member 24 are opened to release the remaining thread. This completes the knotting work, and then moves on to the thread winding work. To wind the thread, first, the intermediate holding mechanism 13 is released to enable feeding of the supply thread B, and the motor 10 is rotated to impart rotation to the clamping plate 4'a. The spool 1 in the spool 2 rotates and the supplied yarn is wound up. When a predetermined amount of yarn is wound, it is detected by a detection mechanism (not shown) and the motor 10 is stopped, and the supply yarn gripping mechanism 22 moves from below the knotting position to the front lower part of the winding drum 16, and the yarn is supplied at this position. Grasp thread B. Next, the thread cutter heating blade 27 comes into contact with the spool side of the supply yarn B held by the supply yarn gripping mechanism 22 to cut the supply yarn B. This completes the winding of the thread onto the spool 1, and when the thread winding work is completed, the push-up member 7 rises again and the insertion groove 7b,
7b to insert and support the shuttle 2, and hold the clamping plate 4.
When a and 4'a are separated from each other to the left and right and the fixing mechanism 3 is released, the push-up member 7 is lowered to store the shuttle 2 in its original position in the storage box 6, and the storage box 6 is moved one pitch. Next, the shuttle 2 in which the spool 1 to be wound is stored is placed directly below the set position. Thereafter, the above steps are repeated and performed continuously.

実行で余剰糸が切断され結節作業が終了する。 First, step S1 (hereinafter, step is simply S1,
Indicated by S2, S3, . . . ) The motor 5c for transporting the storage box rotates to move the storage box 6 one pitch, and the execution of S2 causes the cylinder 7a for lifting and lowering the push-up member to rise, and the push-up member 7 sends the shuttle 2 to the set position. Next, by executing S3, the cylinder 11 is actuated and the fixed hook body 12 is rotated, and the fixed hook body 12 is connected to the thread outlet portion 2 of the shuttle 2.
a is fixed. Then, S4 is executed, and the shuttle 2 is clamped by the clamping plates 4a and 4'a by the operation of the clamping plate clamping cylinders 8 and 9, and by the execution of S5, the cylinder 7a for raising and lowering the pushing up member is lowered, and the pushing up member is lowered. 7 and shuttle 2 separate.
Therefore, the process moves to S6, and by selecting the switch connected to the input terminal of the I/O circuit 31,
If ON, the process goes to YES, and the semi-double knot method is selected; if it is OFF, the process goes to NO, and the double knot knot method is selected. In the case of YES, by executing S7 and S8, the winding rod 21 is rotated twice around the longitudinal axis of the winding drum 16, and then the winding drum 16 is rotated once around the rotation axis to wind the supply yarn B. Wrap it around the body 16, and if NO, S9, S1
By executing steps 0, S11, and S12, the wrapping rod 21
is rotated once, then the winding drum 16 is horizontally rotated once, and then the winding rod 21 and the winding drum 16 are rotated once again in the same manner as described above to wind the supply yarn B around the winding drum 16. By executing S13, the cylinder for advancing and retracting the hook moves forward, causing the hook 17 to pass through the escape groove 16a of the winding drum 16 around which the supply yarn B is wound and project forward of the winding drum 16. Therefore, by executing S14, the winding rod actuating motor 19 is rotated, the winding rod 21 is rotated around the hook 17, and is moved back away from the winding drum 16 to engage the supply yarn with the hook 17a. By executing S15, the hook cylinder 18 is moved backward, and the supply yarn B is pulled out backward through the relief groove 16a in a loop shape. Next, when the winding rod actuating motor 19 is rotated by executing step S16, the winding rod 21 rotates while retreating away from the winding drum 16, but since there is no object to wind around the center of rotation of the thread passing hole 21a. , the execution of S16 is merely an operation of retracting the winding rod 21 away from the winding drum 16. Next, S17, S18, S19,
By executing S20, S21, and S22, first, the chuck opening/closing cylinder 24a is actuated to open the gripping claw 24.
b is closed, and the chuck lifting cylinder 23 is lowered to allow the drawn-out supply yarn B to pass through the loop, and the clamping claw 24b is lowered to below the drawn-out supply yarn, where the chuck opening/closing cylinder 2 is again opened.
4a to open the clamping claw 24b, and the clamping claw 2
The chuck lifting cylinder 23 is lowered with the chuck member 24b left open, and the gripping claw 24b reaches the position of the remaining yarn being pulled out from the spool. The operator picks up the remaining yarn A, raises the chuck lifting cylinder 23 all at once, and inserts the remaining yarn A into the loop of the supplied yarn B. Furthermore, by executing S23, the disengagement cylinder 25 is actuated, and the flip-up rod 25a releases the lock between the supply yarn and the hooking claw, and by executing S24, the tension applying cylinder 14c lowers the slide member 14b to release the yarn. The yarn is pulled, thereby tightening the stitches, and by executing S25, the excess yarn is cut and the knotting operation is completed.

a is released and the clamping claw 24b is opened, and S27
is executed and the cylinder 13 for operating the intermediate holding mechanism is
a is released. When both cylinders are released, it becomes possible to pay out the supply yarn B, and by executing S28, the motor 10 for rotating the clamping plate rotates to wind the supply yarn around the spool. After wrapping is completed, S2
By executing S9, the supply yarn gripping mechanism 22 grips the supply yarn B, and by executing S30, the thread cutting heating blade 27 comes into contact with the supply yarn, and the supply yarn is held between the supply yarn gripping mechanism 22 and the spool 2. cut.

Further, a mechanism for cutting excess yarn protruding from the knot is not necessarily necessary and can be omitted.
Furthermore, cylinders and motors are used to operate each member, but these are not limited to the embodiments, and they may be operated by mutually related cams, links, etc., rather than being used as independent drive means. You can also do it. Furthermore, the control means can also be implemented by attaching a detection mechanism to each operating member and combining it with a sequence circuit, without using a microcomputer. Further, it is sufficient that at least one of the clamping plates of the clamping and rotating mechanism can move toward and away from the other clamping plate and can rotate.
