In each of the proposals described above, a fixed creel for setting up a plurality of bobbins wound with different kinds (different colors or different twists) of yarns is provided for each electronically controlled sample warper body.

[0017] Further, it is possible to omit the yarn changing step, to eliminate the time loss at the time of yarn changing, to simultaneously wind a plurality of yarns around the warping cylinder, and to further shorten the warping work time. An electronically controlled sample warping machine capable of simultaneously warping a plurality of pieces has already been developed and proposed [Patent No. 1,767,706 (US Pat. No. 4,972,562, EP 0375548).
0)].

In this electronically controlled sample warper capable of simultaneously warping a plurality of yarns, since a plurality of yarn introduction means are provided, it is impossible to cope with the conventional fixed creel. Therefore, in addition to the development of an electronically controlled sample warper capable of simultaneously warping a plurality of yarns, a rotary creel capable of warping a plurality of yarns simultaneously has been developed. The development of this rotary creel has enabled simultaneous warping of a plurality of yarns, and as a result, the shortening of aging has been realized.

The rotation of the rotary creel and the rotation of the plurality of yarn introduction means perform a synchronous operation. The mechanism of the synchronous operation will be described with reference to FIGS. FIG. 29 is a schematic installation diagram of an encoder of the electronically controlled sample warper main body, FIG. 30 is a schematic side sectional view of a conventional rotary creel, and FIG. 31 is a block diagram showing the operation principle of the conventional rotary creel.

In FIG. 29, a pulley 98 is linked with a pulley 99 shown in FIG. 25 by a timing belt, and an encoder 97 is attached to an extension of a shaft to which the pulley 98 is fixed.

In FIG. 30, the rotary creel F has two or three or more bobbins 126 wound with the same kind of yarn (the same color or twisted yarn) and / or different kinds of yarn (different color or different twisting yarn). Stand up. 300 is a rotary creel F
An encoder 301 for detecting the rotation of the motor, a motor with a speed reducer 301, a timing pulley 302 fixed to an output shaft 308 of a speed reducer, and a timing pulley 303 fixed to a spindle shaft 307 are linked by a timing belt 309. Reference numeral 304 denotes a tension adjuster for adjusting the tension of the yarn 22, and reference numeral 310 denotes a limit switch for detecting yarn breakage.

The rotary creel F can perform a synchronous operation with the yarn introduction member 6 'while constantly comparing the rotation signals of the encoder 97 and the encoder 300 on the rotary creel F. The position of the bobbin 126 set on the rotary creel F must be relatively the same as the position of the yarn introduction member 6 '.

In FIG. 31, the operation switch 312 has four switches of warping on, warping off, forward rotation inching, and feed rotation inching. Of these, the switch signals of warping on and warping off are sent to the electronically controlled sample warper W main body,
The switch signal of the forward rotation and the forward rotation is a signal for performing positioning between the yarn introduction member 6 ′ and the bobbin 126 around which the yarn 22 is wound around the yarn introduction member 6 ′. It is sent to the control unit 312.

In the synchronous operation control unit 312, the RUN signal (warping ON signal) and the JOG signal (jogging operation signal) sent from the electronic control sample warper W main body, the forward rotation inching signal described above, The feed inching signal is converted and sent to the synchronous operation card 314 as an ENB signal (synchronous operation enable signal), and FWD (forward rotation), REV (reverse rotation), JOG (jogging operation) signals and the like are transmitted to the inverter 313. .

The synchronous operation card 314 has an encoder 9 installed in the main body of the electronically controlled sample warper W.
7 and the encoder 30 installed on the rotary creel F
0 during the warping-on operation and the jogging operation, the rotation angles of the encoder 97 and the encoder 300 are constantly compared, and the yarn introduction member 6 ′ and the yarn 22
In order to keep the relative position of the bobbin 126 around which is wound, a signal is exchanged with the inverter 313.

The inverter 313 gives a rotation signal to the motor 301 with a reduction gear installed on the rotary creel F.
Note that commercially available products can be used for the inverter 313 and the synchronous operation card 314.

Further, after the first yarn row has been wound on the warping drum, the winding of the next yarn row is started so as to be positioned ahead of the first row of yarns, so that the warp drum is wound on the warping drum. Has also proposed an electronically controlled sample warper capable of aligning and winding, which can perform an aligning and warping in order from the lower layer of the yarn, and can be easily wound on a loom beam even if the warping length is long [Japanese Patent No. 2854789]. No. (USP 5,630,26
2, EP 0652310)]. These improved electronically controlled sample warpers have also been very well received.

As described above, the creels used in the electronically controlled sample warper can be classified into two types, namely, a fixed creel and a rotary creel.

The fixed creel has a plurality of bobbins wound with the same kind and / or different kinds of yarns (mainly different kinds of yarns), and can be warped one by one. Although there is an advantage that the warping operation of the warping can be performed, there is a disadvantage that the warping operation time is longer because one yarn is sequentially wound around the warper cylinder.

On the other hand, the rotary creel has a plurality of bobbins on which the same type and / or different types of yarns are wound. In the warping used, the operator first puts the yarn drawn from the rotary creel on a plurality of yarn guiding means, activates the yarn guiding means, and the rotation and the spindle shaft of the rotary creel synchronize. However, it is suitable for warping the repeated design of the yarn initially set on the yarn introduction means.

Therefore, as shown in FIG. 23, solid warping [for example, one color of red thread, FIG.
[For example, repetition of red 1 and white 1, repetition of one S twist and one Z twist, FIG. 23 (b)], 2 to 2 [for example, repetition of two red and two white, two S twists And two Z twists,
FIG. 23 (c)] can be used for warping of a very limited pattern such as 4 to 4 [for example, repeating 4 red and 4 white, repeating 4 S twists and 4 Z twists]. .

This rotary creel has the disadvantage that it is not possible to perform a pattern warping operation other than a limited pattern warping, but it is necessary to simultaneously wind a plurality of yarns around the warping cylinder. There is an advantage that the time is greatly reduced.

For example, in the case of warping warp yarns for weaving a striped woven fabric as shown in FIG. 22, there is a considerable amount of plain fabric, and plain warping using a rotary creel can be performed. Although advantageous from the point of time for aging, it is impossible to use a rotary creel because of the striped portion due to yarns of different colors, and a forced creel has to be used. When a fixed creel is used, the plain warping portion is wound around the warping cylinder one by one, so that it takes time to warp each time, so that the warping operation has to be performed inefficiently. Did not.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems of the prior art, and reduces a warping operation which requires a plain warping and a pattern warping by shortening the warping time. It is an object of the present invention to provide an electronically controlled sample warper capable of performing extremely efficiently.

[0035]

In order to solve the above-mentioned problems, an electronic control sample warper according to the present invention comprises a plurality of conveyors moving on a circumferential side of a warper cylinder toward an end of another side. A belt, a plurality of yarn guiding means rotatably provided on a side surface of the warping cylinder and winding the yarn around the warping cylinder via the conveyor belt, and yarns of different kinds and / or the same kind are wound; An electronically controlled sample warper, comprising: a rotary creel for setting up a plurality of bobbins; and winding the yarn around the warping cylinder, wherein the yarn guide is provided at one end of a base supporting the warping cylinder. A plurality of yarn selection guides provided corresponding to the means and rotatably projected to the yarn exchange position when supplying the yarn, and rotatably stored at the standby position when storing the yarn, and selecting the yarn of the rotary creel. A select guide device is provided.

When the warping operation is started, the simultaneous warping of two or more yarns or the warping of only one yarn can be freely controlled according to the preset pattern data. It is preferable that the selection and storage of the yarn can be selected by the yarn selection guide.

Needless to say, it is necessary to provide a thread selection guide for the total number of the rotary creels (the number of bobbins). In addition, it is preferable to use an endless conveyor belt as the plurality of conveyor belts that move on the circumferential side surface of the warping cylinder in the direction of the end of the other side surface.

In the case of simultaneous warping of two or more yarns, the rotation of the rotary creel and the rotation of the plurality of yarn guiding means perform a synchronous operation, and the yarn guiding means and the rotary creel correspond to each other. The yarn selection guide is configured to be able to deliver the yarn.

In the case of simultaneous warping of a plurality of yarns, it is necessary that the rotation of the yarn introduction means and the rotary creel rotate synchronously. Synchronous rotation can be employed in either an electrical or mechanical configuration. When the rotary creel does not rotate, the yarns on the rotary creel can be replaced one by one.

In the case where the simultaneous warping of two or more yarns or the warping of only one yarn is performed, the moving amount of the conveyor belt can be controlled in accordance with the number of warping yarns. . In other words, in the case of simultaneous warping of a plurality of belts, the amount of movement of the conveyor belt should be larger than in the case of single warping, and the warping density should be controlled to be substantially equal even if the number of warpings changes.

When warping one yarn, only one yarn guiding means is used, and the rotary creel is used in a stationary state.

During synchronous operation and when not rotating,
The yarns on the rotary creel can be selected by the yarn introduction means in order, and at the same time, the order can be freely selected as long as the yarns are not twisted.

It is preferable to provide a yarn retraction device at the tip of the rotary creel in order to accelerate the storage of the yarn of the rotary creel.

The warping method of the present invention is a method using an electronically controlled sample warper equipped with a rotary creel,

Can be performed. Preferably, the rotary creel further includes a tension adjuster, a yarn holding device, a yarn break detector, and a yarn pullback device.

The yarn pulling-back device can apply an appropriate tension necessary for the yarn being warped (the yarn to be supplied), and can quickly loosen the yarn generated at the time of yarn exchange on the creel side (bobbin side). It is preferable that the thread (the inactive thread) housed in the thread selection guide can be always pulled back to a tension force.

The first aspect of the yarn pulling-back device of the present invention is as follows.

Set the power and apply an appropriate tension to the yarn during warping of the yarn, but the take-up reel does not rotate.On the other hand, when the yarn becomes loose, the take-up reel rotates to move the yarn in the traveling direction. It is characterized in that the slack of the return yarn in the opposite direction can be quickly eliminated.

The urging mechanism may be a motor or a spring means. More preferably, the urging force on the yarn can be adjusted arbitrarily.

A second aspect of the yarn pulling-back device of the present invention is as follows.

Therefore, the guide plate 112, its related members, and their operations will be described with reference to FIGS.

The guide plate 112 has a pair of plate plates raised and closed and opened and closed by the guide plate driving device 146, and the guide plate 112 is at rest (closed and closed) as shown in FIGS. 13 and 14, and as shown in FIGS. 15 and 16. It is possible to take two states of the operating state (wake and open). By raising and opening the plate during operation, it is possible to effectively prevent a plurality of yarns supplied from the rotating bobbin 126 from becoming entangled.

The guide plate 112 only needs to act so that a plurality of yarns are not entangled.
As shown in FIG. 17, the guide plate 112 is constituted by a pair of plate plates, and other than the structure in which the plate plate is raised and closed and opened and closed, as shown in FIG. 17 and FIG. Guide plate 112

Accordingly, the plurality of yarns 22 wound on the plurality of bobbins 126 are respectively transferred to the yarn holding device 12.
During the warping operation, the plurality of bobbins 126 rotate in synchronization with the rotation of the yarn introduction means 6 while passing through the yarn return device 118 and the guide plate 112 while the spindle shaft 124 rotates. It is guided by the yarn means 6 and wound around the warper cylinder A. On the other hand, during the warping pause, the yarn 22 wound on the bobbin 126 passes through the yarn holding device 120, the yarn return device 118, and the guide plate 112,
The yarn is guided by the yarn selection guide device 27 and stored therein.

The yarn return device 118 serves to release the yarn 22 when the yarn 22 is relaxed and to eliminate the relaxed state. Any device that performs the return operation can be used, and FIG. 9 and FIG. The preferred embodiment has been described.

The yarn pulling-back device 118 shown in FIGS. 9 and 10 allows the yarn to be quickly pulled back by using an urging means such as a motor or a spring means capable of applying a predetermined urging force to the yarn. This is a new configuration, which will be described below.

The detailed structure of the yarn retraction device 118 is shown in FIGS. 9 and 10. The yarn retraction device 118 has a take-up reel 452 having a space 450 through which the yarn 22 travels. Reference numeral 454 denotes a base, in which a motor 456 is built. One end of the base 454 is a receiving recess 458 for receiving the take-up reel 452, and a motor shaft 460 of the motor 456 protrudes outward at the center of the receiving recess 458.

The take-up reel 452 is rotatably fitted to the motor shaft 460 through a shaft hole 462 formed at the center thereof. 462 is an electric wire cord connected to the motor 456. Reference numeral 464 denotes a guide rod, which is attached to the upper part of the space 450 and guides the running of the yarn 22. Reference numeral 466 denotes a reel cover for covering the take-up reel 452, the receiving recess 458 and the stud pin 468.

When the yarn 22 is warping, the motor 456 is reversely rotated by the tension of the yarn 22v, and the yarn 22 and the guide rod 464 are rotated by the yarn track 22 shown in FIG.
v and the guide rod position 464v.
When the yarn is loosened during storage of the yarn exchange or during pause, the yarn 22
When no or little tension is applied to the motor, the motor 456 rotates forward due to its rotational force, and the yarn 22 and the guide rod 464 are moved to the yarn orbit 22w and the guide rod position 464w shown in FIG. Then, the slack of the yarn is quickly eliminated.

The motor 456 may be any urging means capable of applying a predetermined urging force in the direction opposite to the yarn traveling direction. For example, a spring means may be used instead of the motor 456.

As the yarn pulling-back device 118, any device having a function of quickly resolving the yarn slack when the yarn becomes slack may be used, and other types of yarn pulling-back devices may be employed. Needless to say.

The yarn retraction device 118 shown in FIG.
Is a novel configuration that allows the yarn to be quickly pulled back using compressed air, and will be described below.

The yarn pulling-back device 118 is a guide tube 2 having an internal space 250 through which the yarn 22 passes.
52. A base body 254 is attached to the distal end of the guide tube 252 via a base holder 255. The base holder 255 supports the support plate 21.
6 fixed on.

The base body 254 has through holes 256 therein.
Are bored in the longitudinal direction, and the distal end of the above-described guide tube 252 is fitted into the base end of the through hole 256.

Reference numeral 258 denotes an air nozzle.
Is inserted and fitted into the through hole 256 from the opening at the tip end of the hole. The distal end of the air nozzle 258 is formed to have a small diameter, and an air blowing space 260 is provided between the outer peripheral surface of the distal end of the air nozzle 258 and the inner peripheral surface of the through hole 256.
Is inserted loosely into the central portion of the through hole 256 so as to be formed. The air blowing space 260 is configured to blow air into the internal space 250 in a direction opposite to the traveling direction of the yarn 22, that is, the air blowing space 261 is configured to open in a direction opposite to the traveling direction of the yarn 22. I have.

The base end of the air nozzle 258 is formed to have a large diameter, and is fitted to the front end of the through hole 256. A thread insertion hole 262 is provided inside the air nozzle 258.
Are perforated in the longitudinal direction, and the thread 22 can be inserted therethrough.

An air inlet 264 having an upper end opening into the air blowing space 262 and a lower end opening downward is formed in a lower portion of the air nozzle 258. An air pipe 266 is attached to the base body 254 by a joint 268 so as to communicate with the air inlet 264. The air pipe 266 is connected to a compressed air source 267 and is connected to the compressed air source 267 or the air pipe 266.
The compressed air is turned on / off (cut off) by turning on / off a solenoid valve 269 provided at an appropriate position. That is, when the solenoid valve 269 is on, the compressed air is introduced into the air inlet 264, and when the solenoid valve 269 is off, the compressed air is shut off.

Reference numeral 270 denotes a ceramic guide, and a through hole 272 for inserting a thread is formed in the center of the ceramic guide. The ceramic guide 270 functions to attach the base end of the guide tube 252 to the opening 274 of the base plate 216 a of the support plate 216. 276 is a ceramic ring attached to the opening at the tip of the air nozzle 258.

The solenoid valve 26 of the compressed air source 267
9 is turned on / off at the same timing as each of the select solenoids 29 of the select guides 27a to 27j. Therefore, the compressed air flows into the air blowing port 260 only when the yarn 22 is supplied and when the yarn 22 is stored. That is, at the time of supplying and storing the yarn 22, the yarn retraction device 118 is operated, and at the time of supplying the yarn 22 to the yarn introduction means 6, tension is applied to the yarn 22 so that the yarn 22 is fed.
Remove the thread from the bobbin 1
It is pulled back to the 26 side.

The solenoid valve 269 of the compressed air source 267 and the select solenoids 29 of the select guides 27a to 27j are NO. 1 select solenoid 29 and N
O. 1 solenoid valve 269, NO. No. 2 select solenoid 29 and NO. 2, the solenoid valve 269,
NO. 3 select solenoid 29 and NO. 3 solenoid valve 269, NO. 4 Select Solenoid 29
And NO. 4 solenoid valve 269, NO. No. 5 select solenoid 29 and NO. 5 solenoid valve 26
9 so as to operate correspondingly.

When the compressed air flows into the air blowing space 260, the compressed air is blown out in a direction opposite to the traveling direction of the yarn, and the air flow is opposite to the traveling direction of the yarn. Therefore, as shown in FIG. 19, the air flow in the suction direction opposite to the yarn traveling direction is completed also in the yarn insertion hole 262 of the air nozzle 258, and the action of pulling back the yarn 22 acts on the yarn.

As a result, the yarn 22 passing through the air nozzle 258 has an effect opposite to the traveling direction of the yarn. If the yarn 22 is loose, the yarn 22 is pulled back. Can act to apply tension. or,
Since the strength of this action is determined by the strength of the compressed air, a commercially available pressure reducing valve (regulator) not shown
Therefore, it is preferable that the source pressure of the compressed air can be adjusted.

In the yarn pulling-back device 118 shown in FIG. 19, an example in which the internal space 250 through which the yarn advances and passes is formed by the guide tube 250 and the base end portion of the base body 254 has been described. As long as a space through which the yarn travels and passes is formed, FIG.
It is needless to say that the yarn 22 can be similarly pulled back even if the guide tube 250 is omitted and only the internal space 250 at the base end portion of the base body 254 is used as shown in FIG. In FIG. 20, the same or similar members as those shown in FIG. 19 are denoted by the same reference numerals, and their operations are the same, so that the description thereof will not be repeated.

Further, the yarn pull-back device 118 shown in FIGS. 9, 10, 19 and 20 is used for the electronically controlled sample warper of the present invention shown in FIGS. 1 to 8 and the conventional electronic warper shown in FIGS. Of course, it is applicable to control sample warpers and other types of electronically controlled sample warpers.

In other words, the yarn returning device 118 can apply an appropriate tension necessary for the warping yarn (yarn to be supplied), and can quickly loosen the yarn generated at the time of yarn exchange on the creel side. It is preferable to be configured so that it can be pulled back to the bobbin (side of the bobbin) and can always apply a force for keeping the tension state to the thread (the inactive thread) stored in the thread selection guide.

It is further preferable that the application force to the yarn can be arbitrarily adjusted.

In the above description, a case has been described where the synchronous operation of the rotary creel F and the yarn introduction rod 6 is electrically performed by the encoders 97 and 300. However, the synchronous operation can be performed mechanically. An example in that case will be described with reference to FIGS.

In the mechanical synchronous operation system shown in FIGS. 7 and 8, the basic structure is the same as the electric synchronous operation system shown in FIGS. The drawings are denoted by the same reference numerals, and only the differences will be described.

In FIG. 7, reference numeral 350 denotes a sprocket wheel, which is provided coaxially with the counter pulley 49. 3
Reference numeral 52 denotes a synchro shaft, which is inserted through the lower portion of the base Y and protrudes in the direction of the rotary creel F. A sprocket wheel 354 is attached to the base end of the synchro shaft 352.
The sprocket wheel 350 and the sprocket wheel 350 are connected by a chain 356.

The tip of the synchro shaft 352 is attached to the lower surface of the base plate 130 of the rotary creel F by a stopper 35.
8,358. Reference numeral 360 denotes a clutch / brake unit provided at an appropriate position on the synchro shaft 352, a clutch unit for transmitting and interrupting rotation between the synchro shaft base end 352a and the synchro shaft tip 352b, and a clutch unit in a case where it becomes free The synchro-shaft is constituted by a brake unit for stopping the detour of the tip 352b. 362 is a timing pulley provided at the tip of the synchro shaft 352,
The timing belt 144 is connected to a timing pulley 142 provided on the spindle shaft 124.

With the above configuration, when the main motor 46 is started, the main transmission pulley 47, the sub transmission pulley 48, the counter pulley 49, the V belt 57, the pulley 4, the small gear 5,
The yarn introduction rod 6 is rotated through the rotational movement of the small gear 9, the small gear 10, and the small gear 7.

On the other hand, when a sprocket wheel 350 coaxially mounted on the counter pulley 49 rotates with the rotation of the counter pulley 49, the chain 35
6, sprocket wheel 354, synchro shaft 352,
The front holder 122 and the bobbin 126 are rotated via the rotational movement of the timing pulley 362, the timing belt 144, the timing pulley 142, and the spindle shaft 124, that is, the rotary creel F is rotated.

The rotation of the yarn guide rod 6 and the rotation of the rotary creel F are performed by the rotation of the main motor 46 via the counter pulley 49 and the sprocket wheel 354 mounted coaxially. Are performed in a state of mechanical synchronization.

That is, the drive unit (main motor 46, pulleys 47, 48, 49, etc.) of the yarn guiding rod 6 (yarning means) and the spindle shaft 124 of the rotary creel F have the same ratio via the synchro shaft 352. The rotation of the yarn guide rod 6 and the rotation of the rotary creel can be synchronized with each other.

The on / off control of the clutch means of the clutch / brake unit 360 provided at an appropriate position on the synchro shaft 352 controls the rotation of the synchro shaft base end 352a to the synchro shaft distal end 352.
b, that is, the on / off control of the synchronous rotation of both can be performed, and the synchro shaft tip 352 becomes free when the rotation transmission is further interrupted.
The delusion of b can be stopped by using the braking means.

In other words, when performing simultaneous warping by a plurality of rotary creels F, the synchro shaft base end 35
The synchronous operation of the yarn introduction rod 6 and the rotary creel F is performed while the 2a and the synchro shaft tip 352b are connected by the clutch means.

When performing single warping with the rotary creel F, the synchro shaft base end 352a and the synchro shaft tip 352b are separated by the clutch means so that the rotation of the former is not transmitted to the latter. In addition, the latter is brought into a state in which the latter is braked and stopped by a braking means in order to prevent the latter from being perturbed. As described above, by using the clutch brake unit 360, it is possible to easily perform switching between multiple simultaneous warping or single warping by the rotary creel F.

Whether the rotary creel F is used in a rotating state (simultaneous warping of a plurality of yarns) or in a stationary (stop) state (single warping) is determined in accordance with preset pattern data (thread order). The determination is automatically made, and the rotation or immobility (stop) of the rotary creel F is alternately used. This will be described in more detail with reference to FIG. FIG. 21 is a flowchart showing a procedure for selecting and using simultaneous warping or single warping by the rotary creel F.

The power of the electronically controlled sample warper W is turned on, the warping conditions are input from the program setting unit 78, and the pattern data to be warped is given to the controller 79. Next, when the start switch is turned on, the controller 79 is turned on.
In the selection control section in the table, a plurality of pieces are warped simultaneously (whether the rotating creel F is in a rotating state) or one piece is warped (the rotating creel F
Is set to be immobile or stopped).

When the simultaneous warping of a plurality of yarns is selected, a plurality of yarns are simultaneously wound around the warping drum A by a plurality of yarn introduction means of the rotary creel F, and the wound yarn 2 is wound.
When the number of windings of 2 is counted and reaches a predetermined number of patterns (or the number of plain patterns), creel selection is performed again.

When the single warping is selected, one yarn is wound around the warping cylinder A by one of the plurality of yarn introducing means of the rotary creel F, and the winding is performed. The creel selection is performed again when the number of windings of the attached yarn 22 is counted and reaches a predetermined number of patterns (or the number of plain patterns).

In this manner, the pattern warping (thread order) is set by alternately selecting multiple simultaneous warping and single warping.
When the required number of yarns is wound around the warping cylinder A, the pattern warping operation is completed.

When the simultaneous warping of two or more yarns or the warping of only one yarn is performed, the moving amount of the endless conveyor baltic 500 or the conventional conveyor belt 17 is reduced to the number of warping lines. Correspondingly controlled, that is, in the case of simultaneous warping of a plurality of belts, the warping density is substantially equal even if the number of warping belts is changed by increasing the moving amount of the conveyor belt as compared with the case of single warping. Controlled to be.

The operation of the above configuration will be described. FIG. 22 is an example of a warp design that can be warped with an electronically controlled sample warper equipped with a rotary creel F with a yarn changing function according to the present invention.
