  The above electronically controlled sample weaver, which has been developed by the present applicant, is recognized as being suitable for automatic warping of patterns or patterns by electronic control.

  In the patents proposed by the present applicant and described above, each electronically controlled sampling warping machine has a creel fixed on the body to support a plurality of coils around which different types of son (son of different colors or son twisted) are wound, respectively.

  The present Applicant has also developed and proposed an electronically controlled sampling loom which is adapted to simultaneously weave a plurality of yarns (Japanese Patent No. 1767706 (corresponding to U.S. Patent No. 4,972,562 and EP No. 0375480)) . This electronically controlled sampling warping machine eliminates the need for a wire exchange operation and reduces the time lost to wire exchange to zero. In addition, since a plurality of yarns can be wound simultaneously on a warping drum, a warping operation time can also be reduced.

  In this electronically controlled sampling warping machine adapted to simultaneously weave a plurality of wires, since a plurality of wire introduction means is provided, a conventional fixed creel can not support it. This is the reason why a rotary creel for simultaneously forming a plurality of yarns has been developed in conjunction with the development of the electronically controlled sampling warping machine adapted to simultaneously weave a plurality of yarns. The development of this rotary creel allows a plurality of yarns to be simultaneously hemmed, thereby reducing a warping time.

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

  Referring first to Figure 29, a pulley 98 is associated with the pulley 99 shown in Figure 25 by a timing belt. An encoder 97 is mounted on an extension of a shaft on which the pulley 98 is attached.

  Referring next to FIG. 30, a rotary creel F supports two or more coils 126 around which the same types of yarns (yarns of the same color or yarns with identical twist) and / or different types of yarns (yarns of different colors or wires with different twist) are wound, respectively. Reference numeral 300 designates an encoder for detecting the rotation of rotary drum F; 301, a motor with a gearbox; 302, a synchronizing pulley fixed to an output shaft 308 of the gearbox; and 303, a timing pulley attached to a rotary shaft 307 and operably connected to a timing belt 309. The numeral 304 designates a voltage regulator for adjusting the voltage of the wires 22; and 310, a limit switch for detecting any breakage of wire.

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

  Referring next to FIG. 31, an operating switch assembly 311 is comprised of four switches for warping tripping, warping stop, slow forward rotation, and slow reverse rotation, respectively. . Among the signals from these four switches, switching signals for a warping and a warping warp are transmitted to the electronically controlled sampling beamweaver W, while switching signals for slow rotational movement are provided. forward and a slow rearward rotational movement are transmitted to a synchronized operation control unit 312 for positioning the wire introduction members 6 'and the coils 126, on which the wires 22 are to be gripped by the insertion members of wire 6 'are wound, in correspondence of each other.

  In the synchronized operation control unit 312, a signal RUN (warping trigger signal) and a signal JOG (shake operation signal), which are transmitted from the electronically controlled sampling weaver W, and the aforesaid slow forward rotation and slow rearward rotational movement signals are converted into ENB signals (signals allowing synchronized operation) for transmission to a synchronized operation board 314. In addition, FWD signals (forward rotation), REV (reverse rotation), JOG (shake operation) etc. are transmitted to an inverter 313.

  The synchronized operation card 314 is also connected to an encoder 97 mounted in the electronically controlled sampling warping machine W and to the encoder 300 mounted in the rotary drum F. During a warping trigger and a shaking operation, the angles of rotation of the two encoders 97, 300 are continuously compared, and signals are transferred between the synchronized operation board 314 and the inverter 313 in order to keep the positioning relation between the wire introduction members 6 'and the coils constant. 126 around which the son 22 to be grasped by the wire introduction members 6 'are wound.

  The inverter 313 transmits a rotation signal to the motor 301 with a reducer, located in the rotary creel F. The inverter 313 and the synchronized operation card 314 may be constituted by the commercially available devices.

  The present applicant has also proposed an electronically controlled sampling loom suitable for an aligned winding, wherein once a first column of yarns has been wound on a warping drum, the next column of yarns is wound so that the beginning ends of the yarns of the next line are positioned in front of the yarns of the first column, which allows for a winding warping aligned in order from the lower yarns on the warping drum, and to facilitate the winding of threads on a weaving beam even though a warping length is greater (Japanese Patent No. 2854789 (corresponding to US Patent No. 5,630,262 and EP No. 0652310)). In the same way, this improved version of the electronically controlled sampling warping machine was very favorably received.

  The creels for use in electronically controlled sampling jigs can be classified into two categories: fixed and rotary, as mentioned above.

  The fixed creel has a plurality of coils around which the same types of yarns and / or different types of yarns (mainly different types of yarns) are wound, and is adapted to weave yarns one by one. Therefore, the fixed creel has the advantage of allowing a warping operation for drawing warping. However, since the yarns are wound one by one sequentially around a warping drum, the fixed creel has the disadvantage of requiring a long warping time.

  The rotary creel, on the other hand, comprises a plurality of coils around which the same types and / or different types of son are wound. In warping using a combination of the electronically controlled sampling warping machine adapted to simultaneously weave a plurality of yarns and the rotary creel, an operator first applies yarns taken from the rotary creel to a plurality of introduction means. threads which are then started to repeat a pattern of yarns originally applied to the yarn introduction means with synchronized operation of the rotating yarn introduction means and the rotary creel pin shafts. Thus, the rotary creel is adapted to form a repeated drawing.

  It will be appreciated that the rotary creel is adapted to be used for forming extremely limited designs such as plain weave or canvas (e.g., a single red wire in FIG. 23 (a)), a-one (e.g. , repetitions of one red and one white wire, or one S-twist wire and one Z-twist wire in Fig. 23 (b), two-two (for example, two-wire repetitions) red and two white wires, or two S-twist wires and two Z-twist wires in Figure 23 (c)), four-four (for example, four red wire and four white wire repetitions, and repetitions of four S-twist wires and four Z-twist wires), etc., as shown in FIG. 23.

  While this rotary creel has the disadvantage of being unable to perform a warping operation for drawings other than limited drawings, it has the advantage of considerably reducing a warping time due to the simultaneous windings of a plurality of threads around a warping drum.

  For example, when warping vertical yarns is performed to weave a cross-striped fabric, as shown in FIG. 22, it is advantageous, from the viewpoint of warping time, to perform a warp yarn by using a rotating creel, because the drawing includes a considerable amount of plain part. However, since the cross-striped fabric comprises striped portions with differently colored yarns, the use of the rotary creel is impossible, and a fixed creel must be used. When a stationary creel is employed, threads are wound one by one around a warping drum even for the warp parts, so that warping time is required for each yarn, and this results in an ineffective warping operation without any other possibility.

  The present invention has been realized 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 warping machine which is adapted to perform an extremely effective warping operation comprising both warping and drawing warping in a reduced warping time.

  To solve the above-mentioned problems, the present invention provides an electronically controlled sampling warp 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. to the other lateral end, a plurality of wire insertion means each rotatably mounted on a side surface of the warping drum for winding a wire on the warping drum via an associated conveyor belt, a rotary creel for supporting a plurality of coils around which wires of different types and / or type are wound, and a wire selection guide device for selecting wires in the rotary creel, which has a plurality of wire selection guides arranged in an end portion of a base for supporting the warping drum in correspondence of the means for introduction of wire, each wire selection guide being rotatably arranged to protrude to a wire exchange position when a wire is dispensed and pivoted to retract to a standby position when wire is housed.

  Preferably, when a warping operation is started, simultaneous warping of multiple yarns using two or more yarns or a single yarn warping can be arbitrarily controlled according to predetermined drawing data, and the selection guides of wire allow to select the housing of the son or supply son in the rotary creel.

  Of course, a number of wire selection guides equal to a total number of wires placed in the rotary 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 to the other lateral end, endless conveyor belts are preferably used.

  The rotary creel is rotated in synchronism with the plurality of wire insertion means, and the wire selection guides corresponding to the rotary creel permit the wires to be passed through the wire introduction means when two or more two sons are woven simultaneously.

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

  An extent of movement of the conveyor belts may be controlled in correspondence of the number of threads to be woven when two or more threads are being woven simultaneously or when a single thread is being woven. Particularly, when a plurality of yarns are woven simultaneously, the extent of travel of the conveyor belts is increased, as compared with the single yarn warping, so that a warping density can be controlled to be substantially constant even though the number of threads to be varied varies.

  The present invention also provides a synchronized operating mechanism for an electronically controlled sampling warping machine for winding yarns on a warping drum, said electronically controlled sampling warping machine having a plurality of thread insertion means each rotatably mounted. on a side surface of the warping drum for winding a yarn on the warping drum, and a rotary creel for supporting a plurality of coils around which yarns of different types and / or of the same type are wound. The synchronized operating mechanism comprises a synchronizing shaft disposed outside a path of the wire, and a clutch means attached to a suitable position of the synchronizing shaft, a driving portion of the wire introduction means being coupled to a spindle shaft of the rotary creel via the synchronizing shaft so that on / off control of a synchronized operation of the yarn introduction means with the rotary creel is performed by turning the d 'clutch.

  When a single yarn is hatched, only one yarn introduction means may be employed, with the rotary creel being used in the stationary state.

  During the synchronized operation or the stationary state of the rotary creel, threads in the rotary creel may be neatly selected for the yarn introduction means, and the order may also be selected freely provided that the yarns do not suffer. torsion, that is to say that the son are not shaped into a rope.

  Preferably, a rear wire pulling device is placed adjacent to the front end of the rotary creel to accommodate more quickly wires in the rotary creel.

  The present invention also provides a method of forming yarns using an electronically controlled sampling warping machine having a rotary creel, comprising the step of forming a single yarn or simultaneously forming a plurality of yarns according to predetermined pattern data. .

  When a single yarn is hatched or when a plurality of yarns are woven simultaneously, a warping density is controlled in correspondence with the number of yarns to be woven, so that the warping density is substantially constant even if the number of yarns is son to vary.

  The present invention also provides a rotatable creel comprising a base body, a spindle shaft rotatably arranged on the base body and projecting therefrom, and a plurality of spools attached to the spindle shaft via spool supports. wherein the spindle shaft is driven to simultaneously distribute and rotate a plurality of yarns wound around the plurality of spools, or the spindle shaft is fixed to dispense a single yarn and exchange a yarn to be dispensed. Preferably, the rotary creel is also provided with a tension regulator, a yarn retainer, a yarn break detector, and a yarn pull back device.

  Preferably, the back yarn pulling device can be constructed to communicate a proper tension required for a yarn being dispensed, rapidly retract a loosening yarn, which is eventually the case at the time of a wire exchange, towards the rotary creel (towards an associated coil), and to communicate a force to a wire housed in a wire selection guide (an unused wire) to keep the wire permanently 20. In a first aspect, the rear wire pulling 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 soliciting the rewinder so that it pivots in a predetermined direction, the biasing means being controlled to produce a biasing force which is less than a tension of a thread when a it is being processed and is greater than a thread tension when the thread is released, and the rewinder is used to communicate a suitable tension to a thread when the thread is being formed without rotation, and rotating in response to a loosening yarn for pulling the yarn back in the opposite direction of a direction in which the yarn is running in order to quickly suppress loosening of the yarn.

  The biasing means may be a motor or an elastic means. Preferably, a biasing force on a wire is arbitrarily adjustable.

  In a second aspect, the rear yarn pulling device according to the present invention comprises a base body having an internal space through which a thread passes to pull back the yarn by introducing compressed air into the yarn. internal space in the direction opposite the direction in which the wire is distributed. Preferably, the rear wire pulling device also includes

  an air introducing means having an air inlet lumen via which air is introduced into the internal space in the direction opposite to the direction in which the thread is traveling, wherein a backward pulling force is imparted to the yarn in the direction opposite to the direction in which the yarn is dispensed by introducing compressed air from the air inlet lumen to pull the yarn to the yarn. 'back.

  The present invention is described below with respect to several embodiments with reference to several embodiments with reference to FIGS. 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 departing from the technical idea of the present invention. In Figures 1 to 21, members identical or similar to those of the warper of the prior art illustrated in Figures 24 to 31 are designated by the same reference numerals.

  Referring first to FIG. 1, an electronically controlled sampling warping machine W according to the present invention has, in principle, a structure and operations similar to those of the electronically controlled sampling warping machine illustrated in FIGS. 24 to 31, except for the features and typical operations of the present invention, described later.

  In particular, while the illustrated embodiment of the present invention differs from the warper of the aforementioned prior art with respect to the structure of the rewinder C, the positioning of the opening bars 33, 34, 38 and reduced opening bars 35, 37, removal of the stop plate S, etc., the basic structure and operations of the electronically controlled sampling weaver W themselves are unchanged, so that their description detailed is not repeated. Note that while a controller 79 shown in Fig. 1 has a program debug unit similar to that shown in Fig. 24, the illustration of the program debugging unit is omitted because it would damage the clarity of the figure. Further, 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 rotary creel F. As shown the electronically controlled sampling loom W of the present invention comprises a plurality of wire insertion means 6 rotatably mounted on a side surface of a warping drum A for winding wires 22 around the drum of warper A, and a plurality of wire selection guides 27a-27j, mounted at an end portion of a Y base for supporting the warping drum A, corresponding to the respective wire introduction means 6 so as to 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, similar to the warping machine of the aforementioned prior art. The electronically controlled sampling warp W passes the wires between the wire introduction means 6 and the wire selection guides 27a to 27j to pivot the wires 22 in a predetermined wire order to wind the wires. 22 in the warping drum A. In FIG. 1, the electronically controlled sampling warping machine W also comprises a wire exchange unit G, a lateral cover H, an observation window J, and a section of FIG. motor K. As best shown in FIGS. 1 to 3, in the electronically controlled sampling warping machine of the present invention, a rotating creel F for supporting a plurality of coils 126 (FIG. 11) around which wires of different types and / or of the same type (son of the same color or son with identical twist) are wound, is positioned relative to the plurality of wire selection guides 27a to 27j.

This synchronized operation can be implemented appropriately by an electrical system and a mechanical system. In addition, in the present invention, the rotary creel F may not be rotated and used instead in the stationary state to weave a single yarn in a manner similar to warping using a fixed creel.

  Fig. 4 is a side view generally illustrating an exemplary structure of the electronically controlled sampling warping machine 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 warping machine W has, in principle, a structure and operations similar to those of the conventional electronically controlled sampling warping machine 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 manner similar to the conventional operating mechanism previously illustrated in Figures 29-31, its description is not repeated.

  In particular, this specific embodiment differs from the conventional sampling weaver in terms of the structures of a front drum frame 13 and a rear drum frame 14, due to a modified structural combination of a front drum 502 and a plurality of front drum arms 504 projecting outwardly from the peripheral surface of the front drum 502, due to a modified structural combination of a rear drum 506 and a rear drum arm 508 projecting outwardly from the peripheral surface of the rear drum 506, modifications in a belt conveyor drive mechanism, described later, etc. However, since the basic structure and operations of the electronically controlled sampling warping machine according to this embodiment are unchanged, their detailed description is not repeated.

  It is obvious, while individual organs, devices etc. have been replaced by improved mechanisms to increase efficiency, that the basic functions of the electronically controlled sampling warping machine of this embodiment can be understood by reference to the structure of the electronically controlled sampling hemmerizer As illustrated in Figs. 24-28, various improvements subsequently added to the conventional sampling weaver are therefore not specifically mentioned in the present description.

  As shown, the electronically controlled sampling warping machine W of the present invention comprises a single means or a plurality of wire insertion means 6 rotatably mounted on a side surface of a warping drum A for winding wires. 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 yarn introduction means, each being adapted to move on the peripheral surface of the drum of the invention. warper A 'to the other side end, in a manner similar to that in the aforementioned conventional warping machine. The yarn introduction means 6 wind the yarns 22 around the surfaces of the conveyor belts 500 to wind the yarns 22 along the circumference of the side surface of the warping drum A. As shown in FIG. electronically controlled sampling method W of this embodiment uses endless conveyor belts as conveyor belts 500 in place of the conveyor belts 17 (Fig. 26) used in the conventional warper whose two ends are cut and attached to the drum. training 21.

  By 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 conveyor belt. classic warper.

  Each of the endless conveyor belts 500 is wrapped around a drive roller 514 mounted coaxially on a helical wheel 510 via a drive roller shaft and drawn between two pair guide rollers which are attached to both ends of the drive rollers. a drum radius 16 whose two ends are attached to upper end portions of a front drum arm 504 and a rear drum arm 508. By adjusting a tension roller 522, the belt tension Endless 500 can be modified.

  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 530 is arranged to mesh with the helical wheel 510.

  Referring back to FIG. 4, a servomotor 536 is installed outside the warping drum A to serve as a driving source. A counter-housing 538 is disposed on a base Y. A counter-pulley 540 is arranged on a side surface of the counter-housing 538, and a drive wheel 542 adapted to rotate coaxially with the counter-pulley 540 is arranged on the Another side surface of the counter 538. The counter-pulley 540 is coupled to a motor pulley 536a of the servomotor 536 via a timing belt 544.

  A center gear 546 is coupled to the drive wheel 542 via a chain 548. The center gear 546 is adapted to rotate coaxially with a center gear 550 rotatably mounted on a hollow shaft 1. A feed gear 552 engages with the central gear 550. A power chain wheel 554 is adapted to coaxially rotate with the feed gear 552. The chain wheel 554 and the aforementioned chain wheel 528 are coupled via a chain 556.

  With the transmission mechanism as described above, the servomotor 536, when driven, causes the drive roller 514 to rotate through the motor pulley 536a, the timing belt 544, the counter-pulley 540, the drive wheel 542, the chain 548, the center gear 546, the center gear 550, the feed gear 552, the feed chain wheel 554, the chain 556, the chain wheel 528, the drive wheel worm 530, and the helical wheel 510.

  Therefore, the endless conveyor belts 500, wrapped around the drive roller 514, are rotated.

  Vertical shafts 560 corresponding in number to the number of drum spokes 16 are disposed on the outer surface of the hollow shaft 1. Annular vertical supports 562 are arranged on the peripheral surface of the hollow shaft 1 to support the vertical shafts 560 An annular plate 566 is mounted on an intermediate portion of each of the vertical shafts 560 via a plate boss 564. A beam carrier metal member 570 is attached to the upper end of each of the vertical shafts 560 via an organ. The drum radius 16 is supported on the upper surface of the beam support metal member 570. An intermediate portion of the vertical shaft 560 may be coupled by a reinforcing belt (not shown). shown) to further increase a reinforcing effect for the warping drum A. As described above, the warping drum A can generally be reinforced using the green shafts. 560. The use of such a reinforcing structure may 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 cylindrical reinforcing drum.

  As shown in Figures 4 to 6 and Figures 11 to 16, the rotary creel F comprises a base body 129 which consists of a base plate 130 having wheels 132 fixed on its lower surface, and a front frame 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 by front and rear bearing bearings 136a, 136b. The spindle shaft 124 has its forward end protruding forwardly 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 spindle F is adapted to operate in synchronization with the thread introduction means 6 by continuously comparing a rotation signal from the aforementioned encoder 97 with a rotation signal from the encoder 300 on the rotatable creel F as in the case of the conventional warper illustrated previously in FIGS. 29 to 31.

  A timing pulley 142 is mounted at a projecting portion of the spindle shaft 124 near the front bearing bearing 136a. The synchronizing pulley 142 is coupled to a motor pulley 140 of a retarding motor 138 mounted on the seat plate 130 via a timing belt 144, so that the rotation of the retarding motor 138, when driven, is transmitted to the spindle shaft 124 via the motor pulley 140, the timing belt 144 and the timing pulley 142, which causes rotation of the spindle shaft 124.

  A coil carrier 128 is mounted at the projecting portion of the spindle shaft 124, and a plurality of coils 126 (eight in the illustrated embodiment) are attached at its forward ends. The coils 126 are lined 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 insertion means 6 and simultaneously distribute the wires 22. note that when a single warping operation is performed, the deceleration motor 138 is stopped in response to an instruction from the controller 79, which also causes the spinning creel F to stop turning and thus to become stationary state.

  A front support 122 is mounted at the forward end of the spindle shaft 124 and has a plurality (eight in the illustrated example) of wire retainers (commonly called accumulators) 120 attached to its forward ends.

  In front of each of the wire retainers 120, a rear wire puller 118 is disposed adjacent. A guide plate frame 114 is positioned in front of the rear wire pulling device 118 via a guide plate arm 116 arranged on the front surface side 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 therebetween. 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 rotary creel F. Consequently, the guide plate 112 and the associated members as well as their operation are described with reference to FIGS. 11 to 16.

  The guide plate 112 is designed so that the paired rotary plates are raised and lowered and opened and closed by the guide plate drive unit 146 to adopt an inoperative state (lowered and closed) illustrated on the Figs. 13, 14 and an operating state (raised and opened) illustrated in Figs. 15, 16. During operation, the rotary plates are raised and opened to effectively prevent a plurality of wires distributed from the rotating coils 126 from becoming entangled.

  Since the guide plate 112 serves only to prevent a plurality of wires from becoming entangled, the guide plate 112 may of course be in the form of a single fixed plate member, as shown in FIGS. 17, 18, instead of the guide plate 112 consisting of a pair of rotating plates, such as the example shown in Figs. 15, 16, which is adapted to lower and lift as well as to 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 raised to the operating state.

  A control box 119 controls an operating condition of the rotary creel F. While the control box 119 can be installed in any suitable position, the illustrated embodiment indicates that the control box 119 is installed on the plate Seating 130. A relay housing 123 is fixed in a central portion of the front surface of the front support. Control of the control box 119 to retain the wires 22 in the retaining members 120 is relayed by the relay housing 123.

  Referring now to Figure 12, a plurality of rotating 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 coal 127 is arranged to contact outer peripheral surfaces of the rotating contacts 125.

  A coal support 168 for supporting the coal 127 is connected to the control box 119 via a wire 133.

  An electrical cable 131 is inserted into a hollow portion 124a of the spindle shaft 124, with one end 131a of the cable being attached to a rotating contact 125 and the other being connected to the relay housing 123 above.

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

  Therefore, the plurality of wires 22 wound around the plurality of coils 126, respectively, pass through the wire retainer 120, the back wire puller 118 and the guide plate 112. During an operation of the plurality of coils 126 rotate at the same time as the spindle shaft 124, while remaining synchronized with the rotation of the wire insertion means 6, so that the wires 22 are guided by the feed introduction means. wire 6 to be wrapped around the warping drum A. During a power-down state of the warper, the wires 22n wound around the coils 126 protrude from the wire retainer 120, the wire pull back device 118 and the guide plate 112, then are guided by the wire selection guide 27 and housed therein.

  The rear wire pulling device 118 has a pulling action towards the rear of the wire 22, when the latter is released, to suppress a state of looseness of the wire 22. While any member can be used as a device rear traction of wire 118, provided that it has a rear traction action, Figures 9 and 10 illustrate a preferred embodiment.

  The rear wire pulling device 118 illustrated in Figs. 9, 10 has a new structure which uses biasing means to impart a predetermined biasing force to a wire, such as a motor, resilient means, or the like, for rapid pulling. the wire backwards. Below, the rear wire pulling device 118 is described in detail.

  The structure of the rear wire pulling device 118 is illustrated in detail in FIGS. 9 and 10. The rear wire pulling device 118 includes a rewinder 452 including a gap 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 for receiving the rewinder 452. At a central portion of the recess 458, a motor shaft 460 of the motor 456 projects outwardly. .

  The rewinder 452 is rotatably fitted to the motor shaft 460 via a shaft hole 462 formed at its center. An electrical supply wire 462 is connected to the motor 456. A guide rod 464 is arranged in an upper portion of the space 450 to guide the traveling wire 22. A coil cover 466 is arranged at a predetermined space of the 458 via a bar 468 to cover the rewinder 452. Guiding members 470 (Figure 10) are arranged at the front and rear of the rewinder 452. A guide rod 472 serves, when the wire 22 is released. as shown in 22w, to guide the wire.

  The motor 456 is rotated backward by the tension of the thread 22 on a path 22v as the thread 22 is being formed, so that the thread 22 and the guide rod 464 adopt the thread path. 22v and a guide pin position 464v shown in Fig. 10, respectively. On the other hand, if the wire 22 is released so that it is not stretched at all or tense, for example, when the wire 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 guide pin position 464w shown in Fig. 10, respectively, to rapidly stretch the loose wire. 22.

  The motor 456 may be replaced by any desiccant that can communicate a predetermined biasing force in the direction opposite to the wire running direction. For example, an elastic member may be used in place of the motor 456.

  It is obvious that the rear wire pulling device 118 may be of any other type provided that its function is to quickly eliminate loosening of a wire, if it exists.

  The rear wire pulling device 118 shown in Fig. 19 has a new structure that uses compressed air to allow fast backward pulling of a wire, as described below.

  Referring specifically to Figure 19, the rear wire pulling device 118 includes a guide tube 252 with an internal space 250 formed therein for the passage of a wire 22. A base body 254 is fitted to a portion the 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 an anterior end of the guide tube 252 is inserted into the anterior end of the through hole 256.

  An air nozzle 258 is inserted from an anterior end opening of the through hole 256 and fitted into the through hole 256. The air nozzle 258 has a tapered front end that is slidably inserted into a central portion of the through hole 256 of whereby an arcuate air space 260 is formed between the outer peripheral surface of the anterior end of the air nozzle 258 and the inner surface of the through hole 256. The arcuate air space 260 is defined from in order to allow the introduction of air into the inner space 250 in the direction opposite to the direction in which the wire 22 is traveling, i.e. is structured so that a discharge light of The air is open in the direction opposite to the direction in which the wire 22 is traveling.

  The air nozzle 258 has a diverging proximal end which is fitted into the anterior end of the through hole 256. The air nozzle 258 is provided with a wire through hole 262 extending therein in the longitudinal direction from way that the wire 22 can cross it.

  The air nozzle 258 is provided in its lower part with an air inlet port 264 which has an upper end open to the arcuate air space 260 and a lower end open downwardly. 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 dispensed into the air duct 266 or stopped by turning on or off a solenoid valve 269 disposed at an appropriate position on the compressed air source 267 or the air duct 266. In particular , the compressed air is introduced into the air inlet lumen 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 is provided with a through hole 272 extending at its central portion to allow a wire to pass through the guide. The ceramic guide 270 serves to mount the proximal end of the guide tube 252 into an opening 274 of a proximal end plate 216a of the support plate 216. A ceramic ring 276 is fitted into an opening in the opening. 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-27j. Therefore, the compressed air is dispensed into the air inlet port 264 only when a wire 22 is dispensed and when a wire 22 is stored. Specifically, the rear wire pulling device 118 acts when a wire 22 is dispensed to apply tension on the wire 22 to dispense or feed the wire 22 to the wire introduction means 6, and act when wire 22 is stored to pull back on the wire 22, if released, to the spool 126 when the wire 22 is removed from the wire introduction means 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-27j are electrically connected so that a corresponding operating relationship is established between the selection solenoid 29 No. 1 and the solenoid valve 269 No. 1; selection solenoid 29 No. 2 and solenoid valve 269 No. 2; selection solenoid 29 No. 3 and solenoid valve 269 No. 3; selection solenoid 29 No. 4 and solenoid valve 269 No. 4; selection solenoid 29 No. 5 and solenoid valve 269 No. 5, etc. As the compressed air flows into the arcuate air space 260, the compressed air is discharged in the direction opposite to the direction in which the wire is traveling, so that air flows in the opposite direction of the wire running direction. This causes an air flow to be created within the wire through hole 262 extending through the air nozzle 258 in an absorption direction away from the wire running direction as shown in FIG. FIG. 19, which produces a traction action toward the rear of the wire 22.

  As a result, the wire 22 passing through the air nozzle 258 is acted upon in the direction opposite to its direction of travel, a backward pull being applied if the wire 22 is released, or a voltage being applied to it. the wire 22 if it is stretched. Since the magnitude of this action is dictated by the level of the pressure of the compressed air, a commercially available reducing valve (regulator) is preferably used to adjust the original pressure of the compressed air.

  In the rear wire pulling device 118 illustrated in Fig. 19, the inner 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 inner space 250 is only required to allow a wire to pass therethrough, the guide tube 250 may be omitted to use only the inner space 250 in the proximal end portion of the body of the body. base 254, as shown in FIG. 20, in which case the wire 22 can of course be pulled back in a similar manner. Note that in Figure 20, members identical or similar to those shown in Figure 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 pulling device 118 illustrated in FIGS. 9, 10, 19, 20 may be applied to the electronically controlled sampling warping machine of the present invention illustrated in FIGS. 1 to 8, the conventionally electronically controlled sampling warping machine in FIGS. 24 to 27, and any other type of electronically controlled sampling warping machine.

  Essentially, the rear wire pulling device 118 is preferably constructed to communicate a proper required tension to a wire being fed (distributed wire), quickly pulling back a wire which could have been loosen during a wire exchange to the creel (coil), and communicate a force to permanently maintain a wire housed in a wire selection guide (wire not used) in a voltage 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 insertion means 6 is performed electrically using the coders 97, 300. Alternatively, this synchronized operation can also be obtained mechanically. An example of a mechanically obtained synchronized operation is described below with reference to FIGS. 7 and 8.

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

  Referring specifically to Figure 7, a pinion 350 is arranged coaxially with a counter-pulley 49. A synchronizing shaft 352 passes under a base Y and projects toward the rotary creel F. A pinion 354 is attached to a proximal end of the synchronizing shaft 352, and the pinion 354 and the pinion 350 are coupled via a chain 356.

  The synchronizing shaft 352 has an anterior end attached to the bottom of the seat plate 130 of the rotary creel F with gaskets 358. A clutch brake unit 360 is disposed at a suitable position on the synchronizing shaft. 352, and is comprised of a clutch portion for transmitting and stopping rotations between a synchronous shaft proximal end 352a and an anterior sync shaft end 352b, and a brake portion for stopping unnecessary movements of the anterior end of synchronization shaft 352b when it becomes free. A timing pulley 362 is disposed at the forward end of the timing shaft 352, and is coupled to the timing 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 insertion means 6 is rotated via 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 coaxially mounted on the counterpouled 49 is rotated with the counter-pulley 49, a front support 122 and a coil 126 are rotated, that is to say that the creel rotary F is rotated through rotations of chain 356, pinion 354, timing shaft 352, timing pulley 362, timing belt 144, timing pulley 142, and spindle shaft 124.

  The rotation of the wire insertion means 6 and the rotation of the rotary creel F are mechanically synchronized since the rotary drive is performed by the main motor 46 via the counter-pulley 49 mounted coaxially and the pinion 354.

  In other words, parts for driving the wire insertion means 6 (including the main motor 46, the pulleys 47, 48, 49, etc.) and the spindle shaft 124 of the rotary creel F are coupled via the shaft synchronization 352 at the same ratio, so that the wire insertion means 6 can be rotated in synchronization with the rotary creel F. The transmission and interruption of rotations between the proximal end of synchronizing shaft 352a and the synchronous shaft front end 352b, i.e. the synchronous rotations of the two ends, can be triggered or stopped by turning on or off a clutch means of the brake unit. clutch 360 disposed at a suitable position on the synchronizing shaft 352, and unnecessary movements of the synchronous shaft front end 352b when it becomes free as a consequence of the interruption of the transmission of the synchronization shaft 352b. This rotation can be braked by using the brake portion of the clutch brake unit 360.

  When a plurality of yarns are woven simultaneously using the rotary creel F, the synchronous shaft proximal end 352a is connected with the synchronous shaft anterior end 352b via the clutch means to enable synchronized operation. wire introduction means 6 and rotary creel F. On the other hand, when a single wire is hatched using the rotary creel F, the proximal end of synchronizing shaft 352a is disconnected from the front end. synchronizing shaft 352b by the clutch means to prevent rotation of the end 352a being transmitted to the end 352b, and the end 352b is stopped by the brake means to prevent movement thereof useless. In this way, the rotary creel F can be easily switched between the simultaneous yarning of multiple yarns and the single yarn packing using the clutch brake unit 360.

  The use of rotary creel F in the state of rotation (simultaneous warping of multiple yarns) or in the stationary state (inoperative) (single yarn warping) is determined automatically according to predetermined drawing weave data (order of wires), and the state of rotation and the stationary (inoperative) state of the rotary creel F are alternately selected for use. This procedure is described in more detail with reference to Fig. 21. Fig. 21 is a flowchart illustrating the selective use of the rotary creel F between the simultaneous warping of multiple yarns and the single yarn warping.

  The electronically controlled sampling warping machine W is turned on, and a warping condition is entered from the program tuning unit 78 to communicate to the controller 79 pattern 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 simultaneous warping of multiple yarns (rotational creel F in rotational state) or warping of yarn. single (rotary creel F stationary or inoperative).

  When 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 rotary creel F. The number of coiled yarns 22 is counted, and selecting a creel is performed again when the count reaches a predetermined number of drawing threads (or a predetermined number of canvas weave threads).

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

  In this way, the pattern warping is performed according to the predetermined pattern data (yarn order) by alternately selecting the simultaneous warping of multiple yarns and the single yarn warping. When a requisite number of yarns have been wrapped around the warping drum A, the drawing warping operation is completed.

  When simultaneous warping of multiple yarns using two or more yarns or single yarn warping using a single yarn is performed, the aforementioned 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 woven. In particular, the extent of movement of the conveyor belts 500 is increased for the simultaneous warping of multiple yarns, as compared to the single yarn warping, so that a warping density is substantially equal even if the number of yarns ourdis 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 woven by the electronically controlled sampling loom having the rotary creel F having the yarn exchange function according to the present invention. Below, a description is given of how to proceed with the warping of the illustrated vertical wire pattern.

  The vertical wire pattern shown in Fig. 22 is made by repetitively patterning 10 times a pattern repeat of 442 threads to obtain a width of 200 cm 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 shown in Fig. 22, the rotary creel F can be operated in the following manner. For the leftmost region consisting of a total of 200 threads comprising repetitions of two red threads and two alternating white threads, eight threads can be threaded simultaneously, so that the rotary creel F is driven into an operating mode. synchronized. In the next region of ten red threads, a region of two white threads and a region of ten red threads, the threads are woven one by one, so that the spinning creel F leaves the simultaneous operating mode at a predetermined position. Then, in the following region consisting of a total of 200 threads comprising repetitions of two red and two alternating white threads, eight threads can again be warped simultaneously, so that the spinning creel F is driven into the synchronized operation.

  First, the chain design is entered into the controller 79 via a dedicated program debugging device or personal computer, and then warping conditions including a warp width, the total number of threads to be wired. , and a warping length are entered.

  Then, four red and four white threads are prepared and mounted on the reels 126 of the rotary creel F having predetermined numbers. In particular, a red wire 22a is mounted on a coil 126a (No. 1); a red wire 22b on a coil 126b (No. 2); a white wire 22c on a coil 126c (No. 3); a white wire 22d on a coil 126d (No. 4); a red wire 22e on a coil 126e (No. 5); a red wire 22f on a coil 126f (No. 6); a white wire 22g on a 126g coil (No. 7); and a white wire 22h on a coil 126h (No. 8). Then, each of the threads is threaded into the thread retainer 120, the thread break sensor 121 and the corresponding back thread puller 118.

  Then, the wires are collectively attached to the wire attachment member E which is disposed on the rear side of the wire selection guide 27 disposed in front of the base Y. Since the wire attachment member E comprises a magnet it can easily be fixed.

  (1) The red wire 22a mounted on the reel 126a No. 1 of the rotary creel F is housed in a wire selection guide 27a No. 1.

  (2) The red wire 22b mounted on the bobbin 126b No. 2 of the rotary creel F is housed in a wire selection guide 27b No. 2.

  (3) The white wire 22c mounted on the bobbin 126c No. 3 of the rotary creel F is housed in a wire selection guide 27c No. 3.

  (4) The white wire 22d mounted on the bobbin 126d No. 4 of the rotary creel F is housed in a wire selection guide 27d No. 4.

  (5) The red wire 22e mounted on the choke roll 126e No. 5 is housed in a wire selection guide 27e No. 5.

  (6) The red wire 22f mounted on the reel 126f No. 6 of the rotary creel F is housed in a wire selection guide 27f No. 6.

  (7) The white wire 22g mounted on the bobbin 126g No. 7 of the rotary creel F is housed in a wire selection guide 27g No. 7.

  (8) The white wire 22h mounted on the reel 126h No. 8 of the rotary creel F is housed in a wire selection guide 27h No. 8.

  (9) When a start switch is turned on, it is determined from an instruction of the controller 79 whether the rotary creel F is to be set in a synchronized operation mode or a fixed operating mode (with the drawing of Figure 22, it is determined that the rotary creel F must be set in the synchronized operation mode). Then, the wire introduction means begins to rotate at a low speed.

  (10) When a wire introduction means 6a No. 1 reaches a predetermined selection position, the wire selection guide 27a No. 1 pivots to provide the wire introduction means 6a No. 1 with the wire 22a (red wire).

  (11) When a wire introduction means 6b No. 2 reaches the predetermined selection position, the wire selection guide 27b No. 2 pivots to provide the wire introduction means 6b No. 2 with the wire 22b. (Red string).
