As a traditionally used electronically controlled sampling warper, a structure is known which is described, for example, in Japanese patents Nos. 1529104, 1529108 and 1529109, as shown in FIGS. 24 to 28. This known electronically controlled sampling weaver W has a hollow shaft 1 (FIG. 24). Driving and driven shafts 2, 3 project centrally from opposite ends of the hollow shaft 1. A small gear 5 fixed to a pulley 4 and a pulley 99 are mounted with play on the driving shaft 2, while a small gear 7, to which a wire introduction means 6 is fixed, is mounted with play on the driven shaft 3 at the distal end.

  The electronic controlled sampling warper

  ment above, which was developed by the present applicant, is recognized as being suitable -to an automatic warping of patterns or drawings by electronic control. In the patents proposed by the present applicant and described above, each electronically controlled sampling warper is provided with a fixed creel on the body to support a plurality of coils around which different types of wires (wires of different colors or wires with different twists) are

rolled up, respectively.

  The present Applicant has also developed and

  proposed an electro- controlled sampling warper

  which is suitable for simultaneously warping a

  plurality of wires (Japanese patent No. 1767706 (corres-

  according to U.S. Patent No. 4,972,562 and EP No. 0375480)).

  This electronically controlled sampling warper eliminates the need for a wire exchange operation and

  reduces the waste of time spent on wire exchange to zero.

  Furthermore, since a plurality of threads can be wound simultaneously on a warping drum, a

  warping time can also be reduced.

  In this electronically controlled sampling warper suitable for simultaneously warping a plurality of threads, since a plurality of thread introduction means is provided, a conventional fixed creel cannot support it. This is the reason why a rotary creel to simultaneously warp a plurality of threads has been developed, in conjunction with the development of the electronically controlled sampling warper suitable for simultaneously warping a plurality of threads. The development of this rotary creel allows a plurality of wires to be simultaneously warped, which allows

decrease a warping time.

  The rotary creel is rotated in synchronization with the rotation of the plurality of wire introduction means. A synchronized operating mechanism used in the electronically controlled sampling warper is described below with reference to Figures 29 to 31. Figure 29 is a diagram illustrating how an encoder is mounted in the conventional electronically controlled sampling warper , Figure 30 is a schematic side cross-sectional view of the conventional rotary creel, and Figure 31 is a block diagram illustrating the principles of

  operation of the classic rotary creel.

  Referring firstly to FIG. 29, a pulley 98 is associated with the pulley 99 illustrated in FIG. 25 by a synchronization belt. An encoder 97 is mounted on an extension of a shaft on which the pulley 98 is fixed. With reference then to FIG. 30, a rotary creel F supports two or more of two coils 126 around which the same types of wire (wires of the same color or wires with identical twist) and / or different types of wires (wires of different colors or wires with different twist) are wound, respectively. The reference numeral 300 designates an encoder for detecting the rotation of the rotary creel F; 301, a motor with a reduction gear; 302, a synchronization pulley fixed to an output shaft 308 of the reduction gear; and 303, a synchronization pulley fixed to a rotary shaft 307 and operatively connected to a synchronization belt 309. The reference numeral 304 designates a tension regulator for adjusting the tension of the threads 22; and 310, a limit switch for detecting

any possible wire breakage.

  This rotary creel F can operate in synchronization with the wire introduction members 6 ′ while rotation signals are continuously compared between the above-mentioned encoder 97 and the encoder 300 on the rotary creel F. The position of the coils 126 must be supported on the rotary creel F must substantially

  coincide with the wire introduction members 6 '.

  Referring next to Figure 31, an operation switch assembly 311 is made up of four switches for warping trigger, warping stop, slow motion in forward rotation, and slow motion in reverse rotation, respectively. . Among the signals from these four switches, switching signals for warping triggering and warping stop are transmitted to the electronically controlled sampling warper W, while switching signals for slow rotating motion forward and a slow backward movement are transmitted to a synchronized operating control unit 312 to position the wire feeders 6 'and the spools 126, on which the wires 22 are to be gripped by the feeders 6 'wire

  are wound, in correspondence of each other.

  In the synchronized operation control unit 312, a RUN signal (warping trigger signal) and a JOG signal (shaking operation signal), which are transmitted from the electronically controlled sampling warper W, and the aforesaid signals of slow movement in forward rotation and slow movement in reverse rotation are converted into signals ENB (signals authorizing synchronized operation) intended to be transmitted to a synchronized operation card 314. In addition, signals FWD (forward rotation), REV (reverse rotation), JOG (shake operation) etc. are transmitted to an inverter 313. The synchronized operating card 314 is also connected to an encoder 97 mounted in the electronically controlled sampling warper W and to the encoder 300 mounted in the rotary canter F. During a warping trip and a shaking operation, the angles of rotation of the two encoders 97, 300 are constantly compared, and signals are transferred between the synchronized operating card 314 and the inverter 313 in order to keep the positioning relationship between the introduction members constant of wire 6 'and the coils 126 around which the wires 22 to be gripped by the members

  wire introduction 6 'are wound.

  The inverter 313 transmits a rotation signal to the motor 301 with a reduction gear, located in the rotary creel F. The inverter 313 and the synchronized operating card 314 can be constituted by the devices

commercially available.

  The present Applicant has also proposed an electronically controlled sampling warper suitable for aligned winding, in which once a first column of threads has been wound on a warping drum, the next column of threads is wound so that the beginning ends of the threads of the next line are positioned in front of the threads of the first column, which makes it possible to produce a winding warp aligned in order from the lower threads on the warping drum, and to facilitate the winding of yarns on a weaving beam even if a warping length is greater (Japanese patent No. 2854789 (corresponding to US patent No. 5 630 262 and EP No. 0652310)). Similarly, this improved version of the electronically controlled sampling warper has

  was very favorably received.

  Canters intended for use in electronically controlled sampling warpers can be classified into two categories: fixed canters

  and rotary canters, as mentioned above.

  The fixed creel has a plurality of coils around which the same types of wire and / or different types of wire (mainly different types of wire) are wound, and is adapted to warp wires one by one. Consequently, the fixed creel has the advantage of allowing a warping operation for design warping. However, since the threads are wound one by one sequentially around a warping drum, the fixed creel has the drawback of requiring a long warping time. The rotary creel, on the other hand, has a plurality of coils around which the same types and / or different types of wires are wound. In warping using a combination of the electronically controlled sampling warper suitable for simultaneously warping a plurality of threads and the rotating creel, an operator first applies threads taken from the rotating creeper to a plurality of insertion means of wire which are then started to repeat a drawing of wires originally applied to the wire introduction means with a synchronized operation of the rotary wire introduction means and the spindle shafts of the rotating creel. Thus, the rotary creel is adapted to

hatch a repeated design.

  Note that the rotary creel is adapted to be used for warping extremely limited designs such as plain weave or canvas (for example, a single red wire in Figure 23 (a)), one-to-one (for example , repetitions of a red wire and a white wire, or an S-twist yarn and a Z-twist yarn in Figure 23 (b)), two-two (for example, two-wire repeats red and two white yarns, or two S-twisted yarns and two Z-twisted yarns in Figure 23 (c)), four-four (for example, repetitions of four red yarns and four white yarns, and repetitions of four S-twisted yarns and four Z-twisted yarns), etc., as shown in Figure 23. While this rotary creel has the disadvantage of being unable to perform a warping operation for drawings other than limited designs, it has the advantage of considerably reducing a warping time due to the simultaneous windings of a no plurality of wires

around a warping drum.

  For example, when the warping of vertical yarns is carried out to weave a cross-striped fabric, as shown in FIG. 22, it is advantageous, from the point of view of the warping time, to warp the fabric in using a rotary creel, because the design includes a considerable amount of plain part. However, since the cross-striped fabric comprises striped parts with threads of different colors, the use of the rotary creel is impossible, and a fixed creel must be used. When a fixed creel is used, threads are wound one by one around a warping drum even for the warping parts of the fabric, so that a warping time is required for each thread, and this results in an ineffective warping operation with no other possibility. The present invention has been carried out with regard to the problems inherent in the aforementioned prior art, and an object of the present invention is to provide an electronically controlled sampling warper which is adapted to perform an extremely effective warping operation comprising both a canvas warp and

  a design warping in a reduced warping time.

  To solve the above-mentioned problems, the present invention provides an electronically controlled sampling warper for winding yarns on a warping drum which comprises a plurality of conveyor belts adapted to move on the peripheral surface of the warping drum. towards the other lateral end, a plurality of thread introduction means each mounted in rotation on a lateral surface of the warping drum for winding a thread on the warping drum via an associated conveyor belt, a rotary creel for supporting a plurality of spools around which threads of different types and / or of the same type are wound, and a device for thread selection guides for selecting threads in the rotary creel, which comprises a plurality of thread selection guides, arranged in an end part of a base for supporting the warping drum in correspondence with the means of thread introduction, each thread selection guide being arranged to pivot in order to project to a thread exchange position when a thread is distributed and to pivot in order to retract to a position

waiting when a wire is housed.

  Preferably, when a warping operation is started, a simultaneous warping of multiple threads using two or more of two threads or a warping of single thread can be arbitrarily controlled according to predetermined design data, and the selection guides of wire allow to select the housing of the wires or supply with wires being in the rotary creel. Obviously, a number of thread selection guides equal to a total number of threads placed in the rotating creel (the number of coils) must be provided. For the plurality of conveyor belts adapted to move on the peripheral surface of the warping drum towards the other lateral end, conveyor belts without

  end are preferably used.

  The rotary creel is rotated in synchronization with the plurality of wire introduction means, and the wire selection guides corresponding to the rotary creel allow the wires to be passed through the wire introduction means when two or more of two

wires are warped simultaneously.

  For a simultaneous warping of a plurality of wires, the wire introduction means and the rotary creel must be rotated in synchronization. Synchronized operation can be implemented by an electrical or mechanical system. When the rotary creel is not rotated, wires in the rotary creel

can be exchanged one by one.

  A range of movement of the conveyor belts can be controlled according to the number of threads to be warped when two or more of two threads are warped

  simultaneously or when a single thread is warped.

  Particularly, when a plurality of threads are warped simultaneously, the extent of movement of the conveyor belts is increased, as compared to the warping of single thread, so that a warping density can be controlled so as to be substantially constant even if the number of threads to be warped varies. The present invention also provides a synchronized operating mechanism for an electronically controlled sampling warper for winding threads on a warping drum, said electronically controlled sampling warper comprising a plurality of thread introduction means each mounted in rotation on a lateral surface of the warping drum for winding a thread on the warping drum, and a rotary creel to support a plurality of coils around which threads of different types and / or of the same type are wound. The synchronized operating mechanism comprises a synchronization shaft disposed outside a path of the wire, and a clutch means fixed at an appropriate position of the synchronization shaft, a drive part of the wire introduction means being coupled to a spindle shaft of the rotary creel via the synchronization shaft so that an on / off control of a synchronized operation of the wire introduction means with the rotary creel

  is performed by on / off of the clutch means.

  When a single thread is warped, only one means of thread introduction can be used, with the creel

  rotary being used in the stationary state.

  During the synchronized operation or the stationary state of the rotating creel, wires in the rotating creel can be selected in an orderly fashion for the wire feeding means, and the order can also be freely selected provided that the wires do not undergo torsion, in other words that the wires are not

fashioned into a rope.

  Preferably, a rear wire traction device is placed adjacent to the anterior end of the rotary block to more quickly accommodate wires in the rotary block. The present invention also provides a method for warping yarns using an electronically controlled sampling warper having a rotating creel, comprising the step of warping a single yarn or simultaneously warping a plurality of yarns in

  function of predetermined drawing data.

  When a single thread is warped or when a plurality of threads are warped simultaneously, a warp density is controlled in correspondence with the number of threads to be warped, so that the warp density is substantially

  constant even if the number of threads to be warped varies.

  The present invention also provides a rotary creel comprising a base body, a spindle shaft arranged in rotation on the base body and projecting from the latter, and a plurality of coils fixed to the spindle shaft via coil supports. , wherein the spindle shaft is driven to simultaneously distribute and rotate a plurality of wires wound around the plurality of coils, or the spindle shaft is fixed to distribute a single wire and exchange a wire for distribution. Preferably, the rotary creel is also provided with a voltage regulator, a wire retaining member, a wire break detector, and a

  rear wire pulling device.

  Preferably, the rear wire traction device can be constructed so as to communicate an appropriate tension necessary for a wire being warped (distributed wire), quickly retracting a loosening wire backwards, which is possibly the case at the time of a wire exchange, towards the rotary creel (towards an associated reel), and communicate a force to a wire housed in a wire selection guide (an unused wire)

  to keep the wire taut at all times.

  According to a first aspect, the rear wire traction device according to the present invention comprises a base, a rewinder arranged in rotation on the base and provided with a space through which a wire passes, and a biasing means for urging the rewinder of so that it pivots in a predetermined direction, the biasing means being controlled so as to produce a biasing force which is less than a tension of a thread when a thread is being warped and which is greater than a tension of a thread when the thread is slackened, and the rewinder is used to communicate an appropriate tension to a thread when the thread is being warped without rotation, and to turn in reaction to a loosening thread to pull towards the back the wire in the opposite direction of a direction in which the wire

  scrolls to quickly remove the loosening of the thread.

  The biasing means can be a motor or an elastic means. Preferably, a biasing force on a wire is arbitrarily adjustable. According to a second aspect, the rear wire traction device according to the present invention comprises a basic body provided with an internal space through which a wire passes to pull the wire backwards by introducing compressed air into the space. internal in the direction opposite to the direction in which the wire is

distributed.

  Preferably, the rear wire traction device also comprises an air introduction means provided with an air inlet light via which air is introduced into the internal space in the direction to the opposite of the direction in which the thread travels, in which a rearward pulling force is imparted to the thread in the direction opposite of the direction in which the thread is distributed by introducing compressed air from the light air inlet to pull the wire

rearward.

  The present invention is described below with respect to several embodiments with reference to several embodiments with reference to Figures 1 to 21. However, it is obvious that the present invention is not limited to the illustrated embodiments, and that various modifications can be made without

  move away from the technical idea of the present invention.

  In FIGS. 1 to 21, members identical or similar to those of the warper of the prior art illustrated in FIGS. 24 to 31 are designated by the

same reference numbers.

  Referring firstly to FIG. 1, an electronically controlled sampling warper W according to the present invention has, in principle, a structure and operations similar to those of the electronically controlled sampling warper illustrated in the figures 24 to 31, except as regards the characteristics and typical operations of this

  invention, described later.

  In particular, while the illustrated embodiment of the present invention differs from the aforementioned prior art warper as regards the structure of the rewinder C, the positioning of the opening bars 33, 34, 38 and reduced opening bars, 37, removal of the stop plate S, etc., the basic structure and operations of the electronically controlled sampling warper W itself are

  unchanged, so their detailed description is not

  not repeated. Note that while a controller 79 illustrated in Figure 1 has a program focus unit similar to that illustrated in Figure 24, the illustration of the program focus unit program is omitted because it would affect the clarity of the figure. In addition, the controller 79 illustrated in Figure 1 differs from the conventional controller in that a creel selection control unit is included to select a rotational state or a stationary (inoperative) state for a rotating creel F. As shown , the electronically controlled sampling warper W of the present invention comprises a plurality of wire introduction means 6 rotatably mounted on a side surface of a warper drum A for winding son 22 around the drum warper A, and a plurality of yarn selection guides 27a to 27j, mounted at an end portion of a base Y for supporting the warping drum A, corresponding to the respective yarn introduction means 6 so as to be pivoted to protrude to a wire exchange position when wires are exchanged and pivoted to retract to a standby position when the wires are housed, of a similar to the warping device of the aforementioned prior art. The electronically controlled sampling warper W passes the threads between the thread introduction means 6 and the thread selection guides 27a to 27j to pivot the threads 22 in a predetermined order of threads for winding the threads 22 on the warping drum A. In FIG. 1, the electronically controlled sampling warping machine W also comprises a wire exchange unit G, a side cover H, an observation window J, and a section of motor K. As best represented in FIGS. 1 to 3, in the electronically controlled sampling warper of the present invention, a rotary creel F to support a plurality of coils 126 (FIG. 11) around which wires of different types and / or of the same type (yarns of the same color or identical twist yarns) are wound, is positioned relative to the plurality of guides

wire selection 27a to 27d.

  Wires 22 in the rotary creel F are accommodated in the plurality of wire selection guides 27a to 27j, respectively, so that the wires 22 in the rotary creel F can be wound sequentially on the

  warping drum A as required.

  In the electronically controlled sampling warper W of the present invention, the rotary creel F must be driven in synchronization with the rotations of the plurality of thread introduction means

  in order to use the rotary block F in the rotational state.

  This synchronized operation can be implemented in an appropriate manner by an electrical system and a mechanical system. Furthermore, in the present invention, the rotary creel F may not be rotated and used instead in the stationary state to warp a single yarn in a manner similar to warping using a fixed creel. FIG. 4 is a side view generally illustrating an example of the structure of the electronically controlled sampling warper according to an embodiment of the present invention which uses an electrically synchronized operating mode. With specific reference to FIG. 4, the electronically controlled sampling warper W has, in principle, a structure and operations similar to those of the conventional electronically controlled sampling warper illustrated previously in FIGS. 24 to 28, except for part of the structure and operations. Since a mechanism for electrically synchronized operation can be implemented in a similar manner to the conventional operating mechanism illustrated previously in Figures 29 to 31, its

description is not repeated.

  In particular, this specific embodiment differs from the conventional sampling warper - as regards the structures of a front drum frame 13 and a rear drum frame 14, due to a modified structural combination a front drum 502 and a plurality of front drum arms 504 projecting outward from the peripheral surface of the front drum 502, due to a modified structural combination of a rear drum 506 and d a rear drum arm 508 projecting outwardly from the peripheral surface of the rear drum 506, modifications to a belt conveyor drive mechanism, described later, etc. However, since the basic structure and operations of the electronically controlled sampling warper according to this embodiment are

  unchanged, their detailed description is not repeated.

  Obviously, while individual organs, devices etc. have been replaced by improved mechanisms to increase efficiency, that the basic functions of the electronically controlled sampling warper of this embodiment can be understood by referring to the structure of the electronically controlled sampling warper shown in Figures 24 to 28, various improvements subsequently added to the conventional sampling warper therefore not specifically mentioned in

this description.

  As shown, the electronically controlled weaving sampler W of the present invention comprises a single means or a plurality of thread introduction means 6 mounted in rotation on a lateral surface of a warping drum A for winding threads 22 around the warping drum A; and a plurality of conveyor belts 500 (16 in the illustrated embodiment) arranged in a substantially circular shape, when viewed from the side of the wire introducing means, each adapted to move on the peripheral surface of the drum. warper A towards the other lateral end, in a similar manner to that in the aforementioned conventional warper. The wire introduction means 6 wind the wires 22 around the surfaces of the conveyor belts 500 to wind the wires 22 along the circumference of the lateral surface of the warping drum A. As shown in FIG. 4, the warping machine electronically controlled sampling W of this embodiment uses endless conveyor belts as conveyor belts 500 in place of conveyor belts 17 (FIG. 26) used in the conventional warper, the two ends of which are cut and fixed

to the drive drum 21.

  Using the endless conveyor belts 500, this embodiment employs a new mechanism for driving the endless conveyor belts 500 in place of a drive mechanism consisting of the conveyor belts 17 and the drive drum 21 in

the classic warper.

  Each of the endless conveyor belts 500 is wound around a drive roller 514 mounted coaxially on a helical wheel 510 via a drive roller shaft and drawn between two guide rollers 15 forming a pair which are fixed at the two ends d drum radius 16, the two ends of which are fixed to upper end portions of a front drum arm 504 and a rear drum arm 508. By adjusting a tension roller 522, the tension of the belt

endless 500 can be changed.

  On the inner surface of the rear drum arm 508, a chain wheel 528 and a worm 530 are arranged side by side via a worm shaft. The worm screw 530 is arranged so as to mesh with the wheel

helical 510.

  Referring again to Figure 4, a servo motor 536 is installed outside the warping drum A to serve as a drive source. A counter-housing 538 is arranged on a base Y. A counter-pulley 540 is arranged on a lateral surface of the counter-housing 538, and a drive wheel 542 adapted to rotate coaxially with the counter-pulley 540 is arranged on the other side surface of the casing 538. The counter-pulley 540 is coupled to a motor pulley 536a of the servomotor 536 via

  a synchronization belt 544.

  A central pinion 546 is coupled to the drive wheel 542 via a chain 548. The central pinion 546 is adapted to rotate coaxially with a central gear 550 rotatably mounted on a hollow shaft 1. A feed gear 552 meshes with the central gear 550. A supply chain wheel 554 is adapted to rotate coaxially with the supply gear 552. The chain wheel 554 and the supply wheel

  chain 528 above are coupled via chain 556.

  With the transmission mechanism as described below

  above, the servomotor 536, when driven, causes the drive roller 514 to rotate via the pulley of

  536a engine, 544 timing belt, counter

  pulley 540, drive wheel 542, chain 548, center sprocket 546, central gear 550, feed gear 552, feed chain wheel 554, chain 556, chain wheel 528, the worm 530, and

the 510 helical wheel.

  Consequently, the endless conveyor belts 500, wound around the drive roller 514, are rotated. Vertical shafts 560 corresponding in number to the number of drum spokes 16 are arranged on the external surface of the hollow shaft 1. Annular vertical supports 562 are arranged on the peripheral surface of

  the hollow shaft 1 for supporting the vertical shafts 560.

  An annular plate 566 is mounted on an intermediate part of each of the vertical shafts 560 via a plate boss 564. A beam support metal member 570 is fixed to the upper end of each of the vertical shafts 560 via a end metal 568. The drum spoke 16 is supported on the upper surface of the beam support metal member 570. An intermediate part of the vertical shaft 560 can be coupled by a reinforcing belt (not shown ) to further increase a reinforcing effect for the warping drum A. As described above, the warping drum A can generally be reinforced by using the vertical shafts 560. The use of such a reinforcing structure can allow a reduction in the weight of the warping drum A much greater than a general reinforcement of the warping drum A by using a drum

cylindrical reinforcement.

  As shown in FIGS. 4 to 6 and FIGS. 11 to 16, the rotary canter F comprises a base body 129 which consists of a seat plate 130 comprising rollers 132 fixed on its lower surface, and a front chassis 134a and a rear frame 134b standing vertically at the front and rear ends of the

seat plate 130.

  Above the frames 134a, 134b, a spindle shaft 124 is rotatably mounted via front and rear cushion bearings 136a, 136b. The spindle shaft 124 has its front end projecting forward from the front frame 134a. An encoder 300 similar to that illustrated previously in FIG. 30 is mounted at the rear end of the spindle shaft 124. The rotary creel F is adapted to operation synchronized with the wire introduction means 6 by constantly comparing a rotation signal coming from the aforementioned encoder 97 with a rotation signal coming from the encoder 300 on the rotary canter F as in the case of the conventional warping machine illustrated previously on the

Figures 29 to 31.

  A synchronization pulley 142 is mounted to a projecting portion of the spindle shaft 124 near the front pillow block 136a. The synchronization pulley 142 is coupled to a motor pulley 140 of a retardation motor 138 mounted on the seat plate 130 via a synchronization belt 144, so that the rotation of the retardation motor 138, when it is driven, or transmitted to the spindle shaft 124 via the motor pulley 140, the synchronization belt 144 and the synchronization pulley 142, which causes a rotation of

the spindle shaft 124.

  A coil holder 128 is mounted to the protruding portion of the spindle shaft 124, and a plurality of coils 126 (eight in the illustrated embodiment) are attached to its anterior ends. The coils 126 are furnished with wires 22 of different types and / or of the same type. Thus, during a warping operation, the rotation of the spindle shaft 124 allows the plurality of coils 126 to rotate in synchronization with the rotation of the wire introduction means 6 and to distribute the wires 22 simultaneously. it will be noted that when a single warping operation is carried out, the deceleration motor 138 is stopped in response to an instruction from the controller 79, which also causes the rotary canter F to stop turning and therefore to become

steady state.

  A front support 122 is mounted at the anterior end of the spindle shaft 124 and comprises a plurality (eight in the example illustrated) of wire retaining members (generally called accumulators) 120

  attached to its anterior ends.

  In front of each of the wire retaining members 120, a rear wire traction device 118 is disposed adjacent. A guide plate frame 114 is positioned in front of the rear wire puller 118 via a guide plate arm 116 arranged on the side

  front surface area of the front support 122.

  A guide plate 112 for collectively guiding the wires 22n consists of a pair of rotating plates, and is positioned in front of the front surface of the guide plate frame 114 with a guide plate drive unit 146 disposed between. A wire break sensor 121 is provided to detect a wire break. It will be noted that the guide plate 112 and the associated members are omitted in FIGS. 4 to 6 since these figures are intended to illustrate schematically the structure of the rotating creel F. Consequently, the guide plate 112 and the associated members as well as their operation is described with reference to FIGS. 11 to 16. The guide plate 112 is designed so that the rotary pairing plates are raised and lowered as well as opened and closed by the guide plate drive unit 146 for adopt an inoperative state (lowered and closed) illustrated in Figures 13, 14 and an operating state (lifted and open) illustrated in Figures 15, 16. During operation, the rotary plates are lifted and opened to effectively prevent a plurality of wires distributed from

  rotating coils 126 to become tangled.

  Since the guide plate 112 only serves to prevent a plurality of wires from becoming tangled, the guide plate 112 can obviously be in the form of a single fixed plate member, as shown in the figures 17, 18, instead of the guide plate 112 consisting of a pair of rotary plates, as the example illustrated in FIGS. 15, 16, which is designed to lower and raise as well as open and close the rotary plates . Alternatively, the guide plate 112 may be constituted by a structure comprising a single guide plate 112 arranged for vertical movement so that the guide plate 112 is

  lowered to the inoperative state and lifted to the inoperative state.

  A control unit 119 controls an operating condition of the rotary creel F. While the control unit 119 can be installed in any suitable position, the illustrated embodiment indicates that the control unit 119 is installed on the plate seat 130. A relay box 123 is fixed in

  a central part of the front surface of the front support.

  The control of the control unit 119 for retaining the wires 22 in the retaining members 120 is relayed by the

relay box 123.

  Referring now to Figure 12, a plurality of rotary contacts 125 are mounted to a portion of the spindle shaft 124 positioned between the pillow bearings 136a, 136b via insulating materials 166 made of nylon or the like. A carbon 127 is arranged to contact external peripheral surfaces of the contacts

turning 125.

  A carbon holder 168 for supporting the coal 127 is connected to the control box 119 via a wire

metallic 133.

  An electric cable 131 is inserted into a hollow part 124a of the spindle shaft 124, with one end 131a of the cable being fixed to a rotary contact 125 and

  the other being connected to the above-mentioned relay box 123.

  In other words, the relay box 123 is electrically connected to the control box 119 so that the wire retention command can be relayed by the

control box 119.

  Therefore, the plurality of wires 22 wrapped around the plurality of coils 126, respectively, pass through the wire retainer 120, the device

  wire pull back 118 and guide plate 112.

  During a warping operation, the plurality of coils 126 rotate at the same time as the spindle shaft 124, while remaining synchronized with the rotation of the wire introduction means 6, so that the wires 22 are guided by the thread introduction means 6 to be wound around the warping drum A. During a state of disarming of the warping machine, the threads 22n wound around the spools 126 exceed the thread retaining member 120, the device wire pull back 118 and guide plate 112 and then are guided by

  the wire selection guide 27 and housed therein.

  The rear wire puller 118 has a

  pulling action towards the rear of the wire 22, when the latter

  this is released, to suppress a state of loosening of the wire 22. While any member can be used as a rear traction device for wire 118, provided that it has a rear traction action, FIGS. 9 and 10

  illustrate a preferred implementation.

  The rear wire traction device 118 illustrated in Figures 9, 10 has a new structure which uses a biasing means to impart a predetermined biasing force to a wire, such as a motor, elastic means or the like to pull quickly the wire backwards. Below, the traction device

  back of wire 118 is described in detail.

  The structure of the rear wire traction device 118 is illustrated in detail in FIGS. 9 and 10. The rear wire traction device 118 comprises a rewinder 452 comprising a space 450 through which a wire 22 passes. A motor 456 is housed in a base 454. The base 454 has a recess 458 at one end to receive the rewinder 452. At a central part of the recess 458, a motor shaft 460 of the motor 456 is

projects outward.

  The rewinder 452 is adjusted in rotation on the shaft

  motor 460 via a shaft hole 462 formed in its center.

  An electrical supply wire 462 is connected to the motor 456. A guide rod 464 is arranged in a part

  upper part of the space 450 for guiding the thread 22.

  A spool cover 466 is arranged at a predetermined space in the recess 458 via a bar 468 to cover the rewinder 452. Guide members 470 (FIG. 10) are arranged at the front and at the rear of the rewinder 452 A guide rod 472 is used, when the

  wire 22 is released as indicated in 22w, to guide the wire.

  The motor 456 is driven in rotation towards the rear by the tension of the wire 22 on a path 22v when the wire 22 is being warped, so that the wire 22 and the guide rod 464 adopt the wire path 22v and a guide rod position 464v illustrated in Figure 10, respectively. On the other hand, if the thread 22 is released so that it is not stretched at all or slightly stretched, for example, when the thread 22 is exchanged or while the warper is inoperative, the motor 456 turns to the front with its own rotational force to bring the wire 22 and the guide rod 464 to a wire path 22w and a position of the guide rod 464w illustrated in Figure 10, respectively, to quickly draw the wire

released 22.

  Motor 456 can be replaced by any biasing member which can impart a predetermined biasing force in the direction opposite to the direction of thread travel. For example, an organ

  elastic can be used in place of the 456 motor.

  It is obvious that the rear wire traction device 118 can be of any other type provided that it has the function of rapidly eliminating a

loosening of a wire, if it exists.

  The rear wire traction device 118 illustrated in FIG. 19 has a new structure which uses compressed air to allow rearward traction

  fast of a wire, as described below.

  With specific reference to FIG. 19, the rear wire traction device 118 comprises a guide tube 252 with an internal space 250 formed therein for the passage of a wire 22. A basic body 254 is adjusted on a part front end of the guide tube 252 via a base support 255. The base support

  255 is fixed on a support plate 216.

  The base body 254 has a through hole 256 extending therein in the longitudinal direction, and a front end of the guide tube 252 is inserted

  in the anterior end of the through hole 256.

  An air nozzle 258 is inserted from a front end opening of the through hole 256 and fitted into the through hole 256. The air nozzle 258 has a conical front end which is inserted with clearance in a central portion of the through hole 256 of such that an arcuate air space 260 is formed between the outer peripheral surface of the anterior end of the air nozzle 258 and the internal surface of the through hole 256. The arcuate air space 260 is defined by so as to allow the introduction of air into the internal space 250 in the direction opposite to the direction in which the wire 22 runs, that is to say is structured so that a discharge light d air is open in the opposite direction of the direction in which

the wire 22 scrolls.

  The air nozzle 258 has a diverging proximal end which fits into the anterior end of the through hole 256. The air nozzle 258 has a wire through hole 262 extending therein in the longitudinal direction, so that the wire 22 can pass through it. The air nozzle 258 is provided in its lower part with an air inlet light 264 which has an upper end open on the air space in

  arch 260 and a lower end open downwards.

  An air duct 266 is attached to the base body 254 with a gasket 268 to communicate with the air inlet lumen 264. The air duct 266 is connected to a source of compressed air 267, so that the compressed air is distributed in the air duct 266 or stopped by switching on or off a solenoid valve 269 arranged in an appropriate position on the compressed air source 267 or on the air duct 266. In particular , the compressed air is introduced into the air inlet light 264 when the solenoid valve 269 is energized, and the compressed air is

  stopped when the solenoid valve 269 is de-energized.

  A ceramic guide 270 has a through hole 272 extending in its central portion to allow a wire to pass through the guide. The ceramic guide 270 is used to mount the proximal end of the guide tube 252 in an opening 274 of a proximal end plate 216a of the support plate 216. A ceramic ring 276 is fitted in an opening to

  the front end of the air nozzle 258.

  The solenoid valves 269 associated with the compressed air source 267 are energized or de-energized in synchronization with the energizing or de-energizing of the respective selection solenoids 29 associated with the selection guides 27a to 27j. Therefore, the compressed air is distributed in the air inlet lumen 264 only when a wire 22 is distributed and when a wire 22 is stored. Specifically, the rear wire traction device 118 acts when a wire 22 is distributed to apply a tension on the wire 22 to distribute or pass the wire 22 to the wire introduction means 6, and acts when wire 22 is stored to exert rearward traction on wire 22, if it is released, towards the coil 126 when wire 22 is extracted from the means

  introduction of wire 6 for storage.

  The solenoid valves 269 associated with the compressed air source 267 and the respective selection solenoids 29 associated with the selection guides 27a to 27j are electrically connected so that a corresponding operating relationship is established between the solenoid

  selection 29 No. 1 and the solenoid valve 269 No. 1; the floor-

  selection no. 29 No. 2 and solenoid valve 269 No. 2; the selection solenoid 29 No. 3 and the solenoid valve 269

  No. 3; the selection solenoid 29 No. 4 and the electro-

  valve 269 No. 4; the selection solenoid 29 No. 5 and the solenoid valve 269 No. 5, etc. As the compressed air flows through the arcuate air space 260, the compressed air is discharged in the direction opposite to the direction in which the wire runs, so that the air flows into the

  direction opposite to the thread running direction.

  This causes an air flow to be created within the thread through hole 262 extending through the air nozzle 258 in an absorption direction opposite to the thread running direction, as shown in the figure 19, which produces a pulling action towards

the back of wire 22.

  Consequently, the wire 22 passing through the air nozzle 258 undergoes an action in the direction opposite to its direction of travel, a rearward traction being applied if the wire 22 is released, or a tension being applied to the wire 22 if it is stretched. Since the extent of this action is dictated by the level of the compressed air pressure, a commercially available reducing valve (regulator) is preferably used to adjust the original pressure of the compressed air. In the rear wire traction device 118 illustrated in FIG. 19, the internal space 250, through which a wire passes, is formed by the guide tube 250 and a proximal end portion of the base body 254, by example. However, since the internal space 250 is only required to allow a wire to pass through it, the guide tube 250 can be omitted to use only the internal space 250 in the proximal end portion of the body. base 254, as shown in FIG. 20, in which case the wire 22 can obviously be pulled backwards in a similar manner. It will be noted that in FIG. 20, members identical or similar to those illustrated in FIG. 19 are designated by the same reference numerals, and their

  description is not repeated since their actions are

* also similar.

  It will be apparent to those skilled in the art that the rear wire traction device 118 illustrated in Figures 9, 10, 19, 20 can be applied to the electronically controlled sampling warper of the present invention illustrated in the figures 1 to 8, the conventional electronically controlled sampling warper in FIGS. 24 to 27, and any other type of sampling warping machine

electronically controlled.

  In essence, the rear wire traction device 118 is preferably constructed so as to communicate an appropriate tension required to a wire being warped (distributed wire), quickly pulling back a wire which may have been relax during a wire exchange to the creel (the coil), and communicate a force to permanently maintain a wire housed in a guide

  wire selection (wire not used) in a tension state.

  More preferably, the force imparted to the wire can be adjustable. In the above embodiment, the synchronized operation of the rotary creel F with the wire introduction means 6 is carried out electrically using the encoders 97, 300. In a variant, this synchronized operation can also be obtained mechanically. An example of synchronized operation obtained mechanically is described below with reference to

Figures 7 and 8.

  The mechanical synchronized operation illustrated in FIGS. 7 and 8 is identical as regards the basic structure to the electrical synchronized operation illustrated in FIGS. 4 to 6, so that identical or similar members are designated by the same reference numbers, and only the different aspects are

described below.

  With specific reference to FIG. 7, a pinion 350 is arranged coaxially with a counter-pulley 49. A synchronization shaft 352 passes under a base Y and projects towards the rotary canter F. A pinion 354 is fixed at a proximal end of the synchronization shaft 352, and the pinion 354 and the pinion 350 are coupled via a

chain 356.

  The synchronization shaft 352 has an anterior end fixed to the underside of the base plate 130 of the rotary block F with linings 358. A clutch brake unit 360 is arranged in an appropriate position on the synchronization shaft 352, and consists of a clutch part for transmitting and interrupting rotations between a proximal end of synchronization shaft 352a and a front end of synchronization shaft 352b, and a brake part for stopping unnecessary movements of the anterior end of synchronization shaft 352b when it becomes free. A synchronization pulley 362 is disposed at the front end of the synchronization shaft 352, and is coupled to the synchronization pulley 142 mounted on the spindle shaft 124 via the

timing belt 144.

  With the structure described above, when a main motor 46 is started, the wire introduction means 6 l0 is rotated by rotations of a main transmission pulley 47, an auxiliary transmission pulley 48 , a counter-pulley 49, a V-belt 57, a pulley 4, a small gear 5, a small gear 9, a small gear 10, and a

small gear 7.

  On the other hand, while the pinion 350 mounted coaxially on the counter-pulley 49 is rotated with the counter-pulley 49, a front support 122 and a coil 126 are driven in rotation, that is to say that the rotary block F is driven in rotation via rotations of the chain 356, of the pinion 354, of the synchronization shaft 352, of the synchronization pulley 362, of the synchronization belt 144, of the pulley of

  synchronization 142, and the spindle shaft 124.

  The rotation of the wire introduction means 6 and the rotation of the rotary creel F are mechanically synchronized since the rotational drive is carried out by the main motor 46 via the counter-pulley 49

  mounted coaxially and the pinion 354.

  In other words, parts for driving the wire introduction means 6 (including the main motor 46, the pulleys 47, 48, 49, etc.) and the spindle shaft 124 of the rotary block F are coupled via the shaft synchronization 352 at the same ratio, so that the wire introduction means 6 can be rotated in synchronization with the rotary creel F. The transmission and interruption of rotations between the proximal end of synchronization shaft 352a and the front end of synchronization shaft 352b, that is to say the synchronous rotations of the two ends, can be started or stopped by activating or deactivating a means for clutching the brake unit d clutch 360 disposed in a suitable position on the synchronization shaft 352, and unnecessary movements of the front end of synchronization shaft 352b when it becomes free as a result of the interruption of the transmission d The rotation can be braked using the brake part of the brake unit

clutch 360.

  When a plurality of wires are warped simultaneously using rotary creel F, the proximal end of synchronization shaft 352a is connected with the anterior end of synchronization shaft 352b via the clutch means to allow synchronized operation wire introduction means 6 and the rotary creel F. On the other hand, when a single wire is warped using the rotary creel F, the proximal end of synchronization shaft 352a is disconnected from the anterior end synchronization shaft 352b by the clutch means to prevent the rotation of the end 352a from being transmitted to the end 352b, and the end 352b is stopped by the brake means to prevent it from having movements useless. In this way, the rotary creel F can be easily switched

  between the simultaneous warping of multiple wires and the

  single wire dissection using the brake unit

clutch 360.

  The use of the rotary creel F in the rotational state (simultaneous warping of multiple threads) or in the stationary state (inoperative) (single thread warping) is automatically determined according to predetermined design weave data (order son), and the state of rotation and the stationary (inoperative) state of the creel

  rotary F are selected alternately during use.

  This way of proceeding is described in more detail with reference to FIG. 21. FIG. 21 is a flow diagram illustrating the selective use of the rotary creel F between the simultaneous warping of multiple threads and

single wire warping.

  The electronically controlled sampling warper

  W is started, and a warping condition is entered from the program development unit 78 to communicate to the controller 79 design data for which warping is performed. Then, a start switch is turned on to cause a creel selection control unit in the controller 79 to select the simultaneous warping of multiple wires (rotary creel F in the state of rotation) or the wire warping single (rotary slider F in the state

stationary or inoperative).

  When the simultaneous warping of multiple yarns is selected, a plurality of yarns are wound simultaneously around the warping drum A by a plurality of thread introduction means of the rotating creel F. The number of wound yarns 22 is counted, and the selection of a creel is carried out again when the count reaches a predetermined number of drawing threads (or

  a predetermined number of canvas weave threads).

  When the single thread warping is selected, a single thread is wound around the warping drum A by a single thread introduction means within a plurality of thread introduction means of the rotary creel F. The number of wound threads 22 is counted, and the selection of a creel is carried out again when the count reaches a predetermined number of drawing threads (or a number

canvas threads).

  In this way, the design warping is performed according to the predetermined design data (thread order) by alternately selecting the simultaneous warping of multiple threads and the warping of single thread. When a required number of threads have been wound around the warping drum A, the drawing warping operation is completed. When the simultaneous warping of multiple yarns using two or more of two yarns or the single warp warping using only one yarn is carried out, the above-mentioned endless conveyor belts 500 or conventional conveyor belts 17 are controlled with respect to a range of displacement in correspondence of the number of threads to be warped. In particular, the range of movement of the conveyor belts 500 is increased for the simultaneous warping of multiple threads, in comparison with the warping of single thread, so that a warping density is substantially equal even if the number of

warped son varies.

  The operations permitted by the above structure are described below. FIG. 22 illustrates an example of a drawing of vertical wires which can be warped by the electronically controlled sampling warper comprising the rotary creel F provided with the wire exchange function according to the present invention. Below,

  a description is given of how to proceed

  the warping of the illustrated vertical thread design.

  The drawing of vertical threads illustrated in FIG. 22 is carried out by repeatedly warping 10 times' a repeating drawing consisting of 442 threads to obtain a

  200 cm warped width and a total of 4,220 threads.

  The warping begins at the left end of Figure 22,

  and ends at the right end of Figure 22.

  For the repetition of drawing as illustrated in FIG. 22, the rotary creel F can be actuated in the following manner. For the leftmost region consisting of a total of 200 threads comprising repetitions of two alternating red threads and two alternating white threads, eight threads can be warped simultaneously, so that the rotary creel F is drawn into an operating mode synchronized. In the next region of ten red threads, region of two white threads and region of ten red threads, the threads are warped one by one, so that the rotary creel F leaves the simultaneous operating mode at a predetermined position. Then, in the next region consisting of a total of 200 threads comprising repetitions of two alternating red threads and two alternating white threads, eight threads can again be warped simultaneously, so that the rotary creel F is located

  driven in synchronized operating mode.

  First, the chain drawing is entered into the controller 79 via a dedicated program development device or a personal computer, then warping conditions including warping width, the total number of threads to be warping, and a

warping length are entered.

  Then, four red wires and four white wires are prepared and mounted on the coils 126 of the rotary slab F having predetermined numbers. In particular, a red wire 22a is mounted on a spool 126a (No. 1); a red wire 22b on a spool 126b (No. 2); a white wire 22c on a spool 126c (No. 3); a white wire 22d on a spool 126d (No. 4); a red wire 22e on a spool 126e (No. 5); a red wire 22f on a spool 126f (No. 6); 22g white wire on 126g spool (No. 7); and a 22h white wire on a 126h spool (No. 8). Then, each of the wires is threaded into the wire retainer 120, the wire break sensor 121 and the rear traction device

118 corresponding to it.

  Next, the wires are collectively fixed on the wire fixing member E which is arranged on the rear side of the wire selection guide 27 disposed in front of the base Y. Since the wire fixing member E

  has a magnet, it can easily be attached.
