In the applicant's patents described above, each is electronically controlled Example warping machine provided with a fixed warp beam on the body for holding a plurality of bobbins around the different types of yarn (Threads of different colors or differently twisted threads) each are cold.

The applicant also has an electronically controlled pattern warping machine winds and proposed that can simultaneously warp a plurality of yarns (Japanese Patent No. 1767706 (corresponding to U.S. Patent 4,972,562 and EP 0 375 480). This electronically controlled pattern warping machine avoids that Need for a yarn changing process so that the time lost in the yarn change to zero is pressed. Furthermore, since a plurality of yarns are on simultaneously a warping drum can be wound, the working time of warping also be reduced.

Since this electronically controlled pattern warping machine, which is also a A plurality of yarns can be warped with a plurality of yarn insertion devices can not be seen from a conventional fixed warp beam get supported. For this reason, a rotary skiving boom is together with the Development of the electronically controlled pattern warping machine that works simultaneously A plurality of yarns can be designed to simultaneously add more number of yarns. The development of this revolving warp beam made it possible light the simultaneous warping of a plurality of yarns and consequently reduces the Warping time.

The rotating warp beam is rotated in synchronism with the rotation of the plurality of yarn insertion devices. The synchronous operating mechanism used in the electronically controlled pattern warping machine is described below with reference to FIGS. 29-31. Fig. 29 is a diagram schematically showing how an encoder is attached to the conventional electronically controlled pattern warping machine, Fig. 30 is a schematic side cross-sectional view of the conventional rotary warping tree, and Fig. 31 is a block diagram showing the outline of the operation of the conventional rotating warping tree.

Referring to FIG. 29, a pulley 98 is connected to the in Fig. Belt 25 shown wheel 99 via a timing belt. An encoder 97 is attached to an extension of a shaft to which the pulley 98 is attached.

Referring to FIG. 30 holds a rotary creel F two or more coils 126 to the same type yarns (yarns of the same color or identically twisted yarns) and / or different types of yarns (yarns of different colors or various of the twisted yarns) respectively are wound. Reference numeral 300 denotes an encoder for detecting the rotation of the rotary warping arm F; 301 a motor with a reducer; and 303 a fixed to a rotary shaft 307 and operatively connected to a timing belt 309 contem bungsriemenrad.

This rotary warping arm F can be operated in synchronism with yarn insertion elements 6 ′, wherein rotation signals between the abovementioned encoder 97 and the encoder 300 on the rotating warping arm F are continuously compared. The position of the spools 126 to be held on the rotary warping beam F must match that of the threading guide elements 6 '.

Referring to FIG. 31, an operating switch assembly 311 is composed of four switches for "Schärung ON", "OFF Schärung", "fine movement in forward rotation," or "fine movement in reverse rotation". Among the signals from these four switches, the switching signals for "warping ON" and "warping OFF" are transmitted to the electronically controlled pattern warping machine W, while the switching signals for fine movement during forward rotation and fine movement during reverse rotation are transmitted to a synchronous operation control unit 312 around the yarn insertion elements 6 'and the coils 126 , on which the yarns 22 to be caught by the yarn insertion elements 6 ' are wound, to be coordinated with one another.

In the synchronous operation control unit 312 , a RUN signal ("arming ON" signal) and a JOG signal (jogging operating signal), which are transmitted from the electronically controlled pattern warping machine W, and the above-mentioned "fine motion on forward rotation" signal and the "fine motion on reverse rotation" signal converted to ENB signals (synchronous operation enable signal) to be transmitted to a synchronous operation card 314 . Further, FWD (forward rotation) REV (reverse rotation), JOG (jogging operation) signals, etc. are transmitted to an inverter 313 .

The synchronous operating card 314 is also connected to an encoder 97 installed in the electronically controlled pattern warping machine W and to the encoder 300 installed in the rotary warping tree F. In the "arming ON" and jogging mode, the angles of rotation of the two encoders 97 , 300 are continuously compared and signals are transmitted between the synchronous mode card 314 and the inverter 313 to determine the positional relationship between the yarn insertion element 6 'and the bobbins 126 , by which the Yarn insertion elements 6 'to be caught Gar ne 22 are kept constant.

The inverter 313 supplies the motor 301 with a reduction, which is arranged in the rotary warping arm F, a rotation signal. The inverter 313 and the synchronous operating card 314 can be implemented by commercially available solutions.

The applicant also has an electronically controlled pattern warping machine wraps, which can wrap in an aligned manner, being after a first Strips (column) of yarn has been wound on a warping drum, the next one Strip of yarn is wound up so that the beginning of the next yarn Strip is placed in front of the yarns of the first strip, creating a Arching with aligned winding becomes possible, in one order from the lower yarns on the warping drum, and winding yarn on a yarn tree or weaving beam, even if the warping length is longer (Japanese Patent No. 2854789 (corresponding to US Patent 5 630 262 and EP 0 652 310)). This improved version of the elek tronically controlled pattern warping machine has been very well received.  

Warping trees for use in electronically controlled pattern warping machines can be divided into two types: fixed warping beams and rotating warping beams, as described above.

The fixed warp beam has a plurality of coils around which the same Types of yarn and / or different types of yarn (mainly different Types of yarn) are wound, and can warp yarns one by one. There The fixed warp beam has the advantage of a warping operation for pattern warping (pattern warping). However, since the yarns are sequentially one around that others are wound around a warping drum, the fixed warp beam has the Disadvantage of requiring a long time for the warping operation.

The rotary warping arm, on the other hand, has a plurality of coils around which the same Chen types and / or different types of yarn are wound. At the archipelago using a combination of the electronically controlled Mu star warping machine, which can simultaneously warp a plurality of yarns, and the An operator first lays out the turnable tree from the turnable tree pulled yarns to a plurality of yarn introducers, which then to start a pattern from originally on the yarn introducer created threads with a synchronous operation of the twist in the threads Repeat guide devices with spindle shafts of the rotary warping boom. Consequently the rotating warp beam is suitable for warping repeated patterns.

As mentioned, the rotary skiving boom can be used for skiving very restricted patterns, e.g. B. a plain warp (e.g. only red yarn in Fig. 23 (a)), a 1: 1 warping (e.g. repetitions of a red yarn and a white yarn or an S-twisted yarn and a Z-twisted yarn in Fig. 23 (b)), a 2: 2 warping (e.g. repetitions of two red yarns and two white yarns or two S-twisted yarns and two. Z-twisted yarns in Fig. 23 (c)), 4: 4 warping (e.g. repetitions of four red yarns and four white yarns and repetitions of four S-twisted yarns and four Z-twisted yarns), etc., as in FIG. 23 illustrated.

Although this rotary warping boom has the disadvantage, except for limited pattern warping He has the advantage of not being able to sharpen patterns, the warping time because of the simultaneous winding of a plurality of yarns around a warp drum significantly reduce.

If e.g. For example, when vertical warping is used to weave a cross-striped textile, as shown in Fig. 22, it is advantageous in view of warping time to perform plain warp using a rotary warp because the pattern has a significant proportion contains simple sections. However, since the cross-striped textile contains stripes with yarns of different colors, the use of the rotary warping is impossible, so that inevitably a solid warping beam must be used. If a fixed warp beam is used, the yarns are wrapped one after the other around a warping drum, even in simple warping sections, so that the warping time is incurred for each yarn, making the warping operation inefficient accordingly, with no alternative.

If a simple yarn is being warmed, only one yarn introducer is required be used, the rotary warp beam used in the stationary state becomes.

During the synchronous operation or the stationary state of the turntable The yarns in the rotary warping tree can be used for the yarn introducer device (s) can be selected in an order, and the order can also be freely selected as long as the yarns are not tangled, as long as so no rope forms.

A yarn return is preferably at the front end of the rotary warping beam device for faster depositing of yarns in the rotary warp beam see.  

The invention further relates to a method for warping yarn un ter using an electronically controlled pattern warping machine with rotary warping, characterized by the warping of a simple yarn or simultaneous warping of a plurality of yarns previously set accordingly pattern data.

Description of the preferred embodiments

The invention is described below with reference to the various exemplary embodiments shown in FIGS. 1-21. However, it goes without saying that the invention is not limited to the illustrated exemplary embodiments and that a large number of modifications can be made without departing from the technical concept of the invention. In FIGS. 1-21 of the conven tional warper illustrated in Figs. 24-31 are to the elements referred to the same or similar elements having the same zugsziffern Be.

Referring to FIG. 1 has an ending modern electronically controlled Mu sterschärmaschine W substantially the same structure and performs similar operations as the illustrated conventional elec tronically controlled sample warper illustrated in FIGS. 24-31, with the exception of particular features and functions described later the invention.

In particular, the following applies: While the illustrated exemplary embodiment according to the invention differs from the conventional warping machine described above with regard to the structure of the rewinding device C, the arrangement of the shed forming rods 33 , 34 , 38 and the sectional shed forming rods 35 , 37 , the removal of the stopper plate S, etc. the basic structure and functions of the electronically controlled pattern warping machine W itself unchanged, so that no further detailed explanation is given. It should be noted that although a controller 79 shown in Fig. 1 is provided with a program setting unit similar to that shown in Fig. 24, the display of the program setting unit has been omitted from the illustration because of the complication when the program setting unit is included. Furthermore, the controller 79 of FIG. 1 differs from the conventional controller in that a warp beam selection control section for selecting a rotating state or a stationary (out-of-operation state) of the rotating warp beam F is included.

As illustrated, the invention electronically controlled Mu sterschärmaschine W to a plurality of yarn introduction means 6 rotatably mounted to a side surface of a warper drum A for winding yarns 22 around the warper drum A, and a plurality Garnauswahlführun gen 27 a- 27 j to an end portion of a base Y for holding the warping drum A are attached to the respective yarn insertion means 6 in such a manner that they are pivoted to a projecting yarn exchange position when yarns are exchanged, and are pivoted back to a standby position when yarns are deposited, in a manner corresponding to the conventional warping machine described above. The electronically controlled sample warper W j spends the yarns between the yarn introduction means 6 and the yarn selection guides 27 a- 27, pivoting about the yarns 22 according to a predetermined yarn courses follow to spend to the yarns 22 to wind on the warper drum A.

In Fig. 1, the electronically controlled sample warper W further to a Garnaustauscheinheit G, a side cover H, a viewing window J, and a motor section K.

As well shown in Figs. 1-3, in the electronically controlled pattern warping machine according to the invention is a rotary warping arm F for holding a plurality of spools 126 ( Fig. 11) to the different types of yarns and / or the same type of yarn (yarns of the same color or identically twisted yarns) are gewic Celtic, installed in a positional relationship to the plurality Garnauswahlfüh stanchions 27 a-27 j.

Yarns 22 are located in the rotary creel F are each guided in the yarn selection plurality a- 27 27 j in such a manner that the yarns 22 can be wound sequentially on the warper drum A in the rotary creel F as required.

In the electronically controlled pattern warping machine W according to the invention the rotary warping arm F must synchronize with the twists of the plurality of yarn Turn the insertion devices in order to groove the rotary warping arm F in the rotating state Zen. This synchronous operation can be suitably with an electrical System or a mechanical run. According to the Rotary warping arm F cannot be rotated and can instead be used in a stationary condition for winding a single yarn in a similar manner as in Skerries can be used using a fixed skewer.

Fig. 4 is a side view that generally shows an exemplary structure of the electronically controlled pattern warping machine according to an embodiment of the present invention that uses an electrical synchronous operation scheme. In particular, FIG. 4 shows that the electronically controlled pattern warping machine W has substantially the same structure and performs operations similar to that of the conventional electronically controlled pattern warping machine previously shown in FIGS. 24-28, with the exception of only part of the structure and of functions. Since a mechanism for the electrical synchronous operation can be carried out by a similar scheme as the conventional operating mechanism previously shown with Figs. 29-31, a description will be omitted again.

In particular, this particular embodiment of the structures of a front differs from the conventional sample warper with respect to the drum frame 13 and a rear drum frame 14, and in view of a modified structure combining a front drum 502 and a plurality of front drum arms 504, the drum extending from the circumferential surface of the front 502 to the outside , a modified structure of combination of a rear drum 506 and a rear drum arm 508 of the circumferential surface of the rear drum 506 protrudes outwardly with respect to modifications in a belt conveyor drive mechanism which will be described later, however, since so on, the basic structure and functions of the electronically controlled Mu sterschärmaschine by are not modified in the embodiment itself, no further detailed description is given.

It goes without saying that although individual elements, devices, etc. have been replaced by improved ones to increase the efficiency, the basic functions of the electronically controlled pattern warping machine according to this exemplary embodiment are based on the structure of the conventional electronic ones shown in FIGS . 24-28 controlled pattern warping machine are understandable, so that a variety of the conventional pattern warping machine improvements subsequently added are not specifically mentioned in this description.

As illustrated, the electronically controlled warping machine W according to the invention has one or a plurality of yarn insertion devices 6 which are / are rotatably mounted on a side surface of a warping drum A for winding yarns 22 around the warping drum A; and a plurality of conveyors 500 (16 in the illustrated embodiment) arranged in a substantially circular shape as viewed from the yarn introducer side, each of which is movable toward the end of the other side on the peripheral surface of the warping drum A, similar to in the conventional warping machine described above. The yarn introducer 6 winds the yarns 22 around the surfaces of the transport belts 500 for winding the yarns 22 along the circumference of the side surface of the warping drum A.

As shown in Fig. 4, the electronically controlled pattern warping machine W according to this embodiment uses endless transport belts as the transport belt 500 instead of the transport belt 17 used in the conventional warping machine 17 ( FIG. 26), both ends of which are cut and attached to the drive drum 21 .

With the use of the endless conveyor belts 500 , this exemplary embodiment uses a new mechanism for driving the endless conveyor belts 500 instead of a drive mechanism of the conventional warping machine constructed from the conveyor belts 17 and the drive drum 21 .

Each of the endless conveyor belts 500 is wound around a drive roller 514 , which is coaxially attached to a worm wheel 510 via a drive roller shaft, and extends between a pair of guide rollers 15 attached to both ends of a drum spoke 16 , both ends of which are at upper end portions a front drum arm 504 and a rear drum arm 508 are attached. By adjusting a tension roller 522 , the tension of the endless belt 500 can be changed.

On the inner surface of the rear drum arm 508 , a sprocket 528 and a worm 530 are arranged side by side and arranged via a worm shaft. The worm 530 meshes with the worm wheel 510 .

Furthermore, Fig. 4 shows that a servo motor 536 is mounted outside the warping drum A as a drive power source. A counter box 538 is arranged on a base Y. On a side surface of the meter box 538 , a meter belt 540 is arranged and on the other side surface of the meter box 538 a coaxial with the meter belt 540 rotatable drive wheel 542 is arranged. The metering belt wheel 540 is coupled via a timing belt 544 to a motor belt wheel 536 a of the servo motor 536 .

A center sprocket 546 is coupled to the drive sprocket 542 via a chain 548 . The center sprocket 546 is coaxially rotatable with a center gear 550 mounted on a hollow shaft 1 . A feed gear 552 is engaged with the center gear 550 . A feed sprocket 554 is rotatable coaxially with the feed sprocket 552 . The sprocket 554 and the aforementioned sprocket 528 are coupled via a chain 556 .

With the above gear mechanisms, the servo motor 536 , when operated, brings the drive roller 514 over the motor pulley 536 a, the timing belt 544 , the counter pulley 540 , the drive wheel 542 , the chain 548 , the center sprocket 546 , the center gear 550 , the Feed gear 552 , feed sprocket 554 , chain 556 , sprocket 528 , worm 530, and worm gear 510 for rotation.

Consequently, the endless transport belt 500 wound around the drive roller 514 is rotated.

Vertical shafts 560 corresponding to the number of drum spokes 16 are attached to the outer surface of the hollow shaft 1 . On the circumferential surface of the hollow shaft 1 , annular vertical holders 562 for holding the vertical shafts 560 are arranged. At an intermediate portion of each of the vertical shafts 560 , an annular plate 566 is introduced via a plate fitting 564 . At the upper end of each of the vertical shafts 560 , a carrier holding metal 570 is fastened via an end metal 568 . The drum spoke 16 is held on the top surface of the carrier holding metal 570 . An intermediate portion of the vertical shaft 516 may be coupled by a reinforcing belt (not shown) to further improve the reinforcing effect for the warping drum A.

As described above, the warping drum A can be generally reinforced using the vertical shafts 560 . The use of such a reinforcement structure can result in a considerably better reduction in weight of the warping drum A compared to a general reinforcement of the warping drum A using a cylindrical reinforcement drum.

As shown in FIGS. 4-6 and in FIGS. 11-16, the rotary warping arm F has a base body 129 , which is formed from a base plate 130 with castors 132 fastened to its bottom surface, and a front frame 134 a and a rear frame 134 b standing vertically at a front end and a rear end of the base plate 130 .

A spindle shaft 124 is rotatably mounted on the frame 134 a, 134 b via front and rear bearing seats 136 a, 136 b (pillow bearings). The front end of the spindle shaft 124 extends forward from the front frame 134 a. An encoder 300 similar to that previously shown in FIG. 30 is attached to the rear end of the spindle shaft 124 . The rotary warping arm F can carry out an operation synchronous with the fermentation guiding device 6 by constantly comparing a rotary signal from the coder 97 mentioned with a rotary signal from the encoder 300 on the rotary warping arm 11 , as is also the case in the case of those previously shown in FIGS. 31 shown conventional warping machine.

A timing pulley 142 is attached to a protruding portion of the spindle shaft 124 adjacent to the front bearing seat 136 (a). The timing pulley 142 is coupled via a timing belt 144 to a motor belt wheel 140 of a deceleration motor 138 (slowdown motor) attached to the base plate 130 , that the rotation of the deceleration motor 138 , when driven, via the motor pulley 140 , the timing belt 144 and the timing pulley 142 is transmitted to the spindle shaft 124 so that it rotates.

A spool holder 128 is attached to the projecting portion of the spindle shaft 124 , and a plurality of spools 126 (in the example shown 8) are attached to its front ends. The bobbins 126 are wound with different types and / or the same type of yarn 22 . Thus, in a warping operation, the rotation of the spindle shaft 124 enables the plurality of bobbins 126 to rotate in synchronization with the rotation of the yarn introducer 6 and to feed the yarns 22 at the same time. It should be noted that in a simple warping operation, the deceleration motor 138 is stopped in response to a command from the controller 79 , which also brings the rotary warping arm F to stop rotation and thus to a steady state.

A front holder 122 is attached to the front end of the spindle shaft 124 and has a plurality (in the example shown 8) of yarn retention elements (generally referred to as accumulators) 120 which are attached to its front ends.

Before each of the yarn retention elements 120 , a yarn return device 118 is arranged adjacent to this. A guide plate frame 114 is arranged in front of the yarn return device 118 via a guide plate arm 116 arranged on the front surface side of the front side holder 122 .

A guide plate 112 for collectively guiding the yarns 22 n is formed of a pair of rotatable plates and disposed in front of the front surface of the guide plate frame 114 with a guide plate drive unit 146 interposed therebetween. A yarn break sensor 121 is provided for detecting a yarn break. It should be noted that the guide plate 112 and the elements associated therewith are omitted in FIGS. 4-6, since these figures show the structure of the rotary warping arm F schematically. Therefore, the guide plate 112 and the elements associated therewith and their functions are described with reference to FIGS. 11-16.

The guide plate 112 is designed so that the pair of rotatable plates is raised and lowered, and opened and closed by the guide plate drive unit 146 , in an inoperative state (lowered and closed) as shown in FIGS. 13, 14 and an operating state (raised and opened). shown in FIGS. 15 to accept the 16th In operation, the rotatable plates are raised and opened to effectively prevent tangling of a plurality of yarns fed from the rotating spools 126 .

Since the guide plate 112 only has to prevent a tangle of a plurality of yarns, the guide plate 112 can of course be embodied by a single solid Plattenele element, as shown in FIGS . 17, 18, in contrast to one formed from a pair of rotatable plates Guide plate 112 as in the example shown in FIGS. 15, 16, the design of which is aimed at raising and lowering and opening and closing the rotatable plates. Alternatively, the guide plate 112 by a structure having a gene only peo guide plate 112 be embodied, which is designed for a vertical movement, so that the guide plate is lowered in an inoperative state 112 and raised into an operating state.

A control box 119 controls an operating state of the rotary warping arm F. While the control box 119 can be installed in any suitable position, the exemplary embodiment shown shows an installation of the control box 119 on the base plate 130 . A relay box 123 is fixed in a central portion of the front surface of the front holder. The control by the control box 119 for retaining the yarns 22 in the yarn retaining elements 120 is mediated by the relay box 123 .

Referring to FIG. 12, a plurality of slip rings 125 attached to a gersitzen between the La 136 a and 136 disposed portion b of the spindle shaft 124 introduced, through insulating materials 166 of nylon or the like. A carbon cloth brush 127 is adapted to receive the outer peripheral surfaces of the slip rings 125 to touch.

A carbon brush holder 168 for holding the carbon brush 127 is connected to the control box 119 via a wire 133 .

In a hollow portion 124 a of the spindle shaft 124, a pulling wire is inserted 131, wherein its one end 131a attached to a slip ring 125 and the other end is connected with the foregoing relay box 123rd In other words, the relay box 123 is electrically connected to the control box 119 , so that the yarn retention control can be switched by the control box 119 .

Accordingly, a plurality of yarns 22 wound around the plurality of bobbins 126 each pass through the yarn retention elements 120 , the yarn retrieval device 118 and the guide plate 112 . During the warping operation, the plurality of bobbins 126 are rotated together with the rotation of the spindle shaft 124 , while a synchronous state is maintained with the rotation of the yarn insertion devices 6 , so that the yarns 22 are guided through the yarn insertion devices 6 in order to be wound around the warping drum A. become. During a skew lock condition, the yarns 22 n wrapped around the bobbins 126 pass through the yarn retainer 120 , the yarn return device 118 and the guide plate 112 and are then passed through the yarn selection guide 127 and housed therein.

The yarn return device 118 has the effect of returning the yarn 22 when there is play to correct play of the yarn 22 . FIGS. 9 and 10 illustrate a preferred embodiment, in which any element can be used as Garnrückbringeinrichtung 118, as long as it is a rear-making effect.

The yarn return device 118 shown in FIGS . 9, 10 shows a novel structure which uses a pulling device to exert a predetermined tensile force on a yarn, such as a motor, a spring or the like, in order to quickly return the yarn. The yarn return device 118 is described in detail below.

The structure of the yarn return device 118 is shown in detail in FIGS . 9 and 10. The yarn return device 118 has a winding wheel 452 with a space 450 through which a yarn 22 passes. A motor 456 is housed in a base 454 . The base 454 has a recess 458 at one end for receiving the rewind wheel 452 . At a central portion of the recess 458 , a motor shaft 460 of the motor 456 projects outward.

The rewind wheel 452 is rotatably fitted on the motor shaft 460 through a shaft hole 462 formed through its center. A power supply cable 462 is connected to the motor 456 . In an upper portion of the space 450 , a guide rod 464 for guiding the running yarn 22 is arranged. With a predetermined distance from the recess 458 , a wheel cover 466 is arranged over a web pin 468 to cover the rewinding wheel 452 . In front of and behind the rewinding wheel 452 , guide elements 470 ( FIG. 10) are arranged. A guide pin 472 is used to guide the yarn when the yarn 22 is playing , as indicated by 22 w.

The motor 456 is w turned back by the tension of the yarn 22 along a trajectory 22, when the yarn is warped 22, so that the yarn 22 and the guide rod to take 464 the Garntrajektorie 22 v and a guide rod position 464 v, as shown in Fig. 10 shown. On the other hand, if the yarn 22 has play so that it is not tensioned at all or is only slightly tensioned, e.g. B. when changing the yarn 22 or outside the operation of the warping machine, the motor 456 rotates forward with its own torque to bring the yarn 22 and the guide rod 464 to a yarn trajectory 22 w and a guide rod position 464 w, as in FIG Fig. 10 shown, and the loose yarn 22 to tension quickly.

The motor 456 can be replaced by any pulling element which can build up a predetermined pulling force in the direction opposite to the yarn transport direction. For example, a spring can be used instead of the motor 456 .

It goes without saying that the yarn return device 118 can also be of another type, as long as it has the effect of quickly eliminating a play in the yarn, if any.

The yarn return device 118 shown in Fig. 19 shows a novel structure that uses compressed air to quickly return yarn as described below.

According to FIG. 19 118 has the Garnrückbringeinrichtung a guide tube 252 formed with an inner space therethrough for traversing a yarn 22,250. A base body 254 is attached to a front end portion of the guide tube 252 via a base holder 255 . The base holder 255 is held on a holding plate 216 .

The base body 254 is formed with a through hole 256 extending in the longitudinal direction, and a front end of the guide tube 252 is inserted into the front end of the through hole 256 .

From a front end opening of the through hole 256 , an air nozzle 258 is inserted and fitted into the through hole 256 . The air nozzle 258 has a tapered forward end which is loosely inserted into a center portion of the through hole 256, and a Lufteinblasraum 260 is formed, although in such a manner that between the outer circumferential surface of the front end of the air nozzle 258 and the in nenoberfläche of the through hole 256th The air injection space 260 is limited to allow air to be introduced into the interior space 250 in the direction opposite to the direction in which the yarn 22 is traveling, that is, it is constructed so that in the direction in which the yarn 22 runs in the opposite direction, an air outlet opening 261 is open.

The air nozzle 258 has a widening proximal end which is fitted in the front end of the through hole 256 . The air nozzle 258 is formed with a yarn through hole 262 extending in the longitudinal direction so that the yarn 22 can pass through.

The air nozzle 258 is formed in a lower section with an air inlet opening 264 which has an upper end opening to the air blowing space 262 and a lower end opening downwards. On the base body 254 , an air pipe 266 is attached via a connecting element 268 in order to communicate with the air inlet opening 264 . The air tube 266 is connected to a compressed air source 267 , so that compressed air can be introduced or stopped into the air tube 266 by opening or closing a solenoid valve 269 arranged at a suitable position of the compressed air source 267 or on the air tube 266 . In particular, the compressed air is introduced into the air inlet opening 264 when the solenoid valve 269 is opened, and the compressed air is stopped when the solenoid valve 269 is closed.

A ceramic guide 270 is formed with a through hole 272 extending through a central portion to allow a yarn to pass therethrough. The ceramic guide 270 serves to attach the proximal end of the guide tube 252 in an opening 274 a 216 a Proximalendplatte Hal teplatte 216th In an opening at the front end of the air nozzle 258 , a ceramic ring 276 is fitted.

The solenoid valves 269 associated with the compressed air source 267 are switched on and off with the same timing as the respective selection solenoids 29 associated with the selection guides 27 a- 27 j. Thus, the compressed air is introduced into the air inlet port 260 only when a yarn 22 is fed and when a yarn 22 is stored. In particular, the Garnrückbringeinrichtung 118 when a yarn 22 is supplied to apply a voltage to the yarn 22, the yarn 22 of the Garneinführeinrich tung 6 supply, and when a yarn is stored 22, the yarn 22 when it gets game serves to return the spool 126 when the yarn 22 is removed from the yarn introducer 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 27 a- 27 j are electrically connected so that a corresponding operative 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; the selection solenoid 29 No. 3 and the solenoid valve 269 No. 3; the No. 4 selection solenoid 29 and No. 4 solenoid valve 269 ; the selection solenoid 29 No. 5 and the solenoid valve 269 No. 5; etc.

When the compressed air flows into the air blowing space 260 , the compressed air is discharged in the direction opposite to the yarn direction, so that the air flows in the direction opposite to the yarn direction. This causes air flow within the yarn through hole 262 extending through the air nozzle 258 in a direction opposite to the yarn direction as shown in FIG. 19, thereby producing the effect of pushing the yarn 22 back.

As a result, a force is exerted in the direction opposite to the running direction of the direction of the guided through the air nozzle 258 yarn 22 to move back or to the yarn 22 when the game gen anzule to the yarn 22 a voltage when it is stretched. Since the magnitude of this force is determined by the level of the pressure of the compressed air, a commercially available reducing valve (regulating device) can preferably be used to adjust the outlet pressure of the compressed air.

In the yarn return device 118 shown in FIG. 19, the interior 250 through which a yarn runs is formed, for example, by the guide tube 250 and a proximal end section of the base body 254 . However, since the inner space 250 only has to let one yarn pass, the guide tube 250 can be left to use only the inner space 250 in the proximal end portion of the base body 254 as shown in FIG. 20, in which case the yarn 22 is of course the same Way can be brought back. It should be noted that identical or similar elements in FIG. 19 are designated with the same reference numerals in FIG. 20 and a repeated description is omitted because of the comparable effect.

It is clear to the person skilled in the art that the yarn return device 118 shown in FIGS . 9, 10, 19, 20 can be used in the electronically controlled pattern warping machine according to the invention shown in FIGS . 1-8, that shown in FIGS . 24-27 conventional electronically controlled pattern warping machine and any other type of electronically controlled pattern warping machine.

In essence, the yarn return device 118 is preferably designed to give a yarn in the warping process (fed yarn) the necessary and suitable tension, to quickly return a yarn play that may occur when changing yarn to the warping beam (bobbin) and to exert a force, to permanently tension a yarn housed in a yarn selection guide (yarn not in use).

It is further preferred that the force exerted on the yarn is adjustable. In the above embodiment, the synchronous operation of the rotary warping tree F with the yarn introducer 6 using the encoders 97 , 300 has been accomplished electrically. Alternatively, this synchronous operation can also be accomplished mechanically. An example of a mechanically accomplished synchronous operation is described below with reference to FIGS . 7 and 8:

The mechanical-synchronous operation shown in FIGS. 7 and 8 corresponds in terms of the basic structure to the electrically synchronous operation shown in FIGS . 4-6, so that identical or similar elements are designated by the same reference numerals and only the different aspects are described below become.

From Fig. 7 it follows that a sprocket 350 is arranged coaxially with a counter pulley 49 . A synchronizer shaft 352 runs below a base Y and extends toward the rotary skiving boom F. A sprocket 354 is attached to a proximal end of the synchronizer shaft 352 , and the sprocket 354 and sprocket 350 are coupled via a chain 356 .

The synchronous shaft 352 has a front end fastened to the base of the base plate 130 of the rotary warping arm F with fastening elements 358 . In a suitable position on the synchronous shaft 352 , a clutch brake unit 360 is arranged and constructed from a clutch section for transmitting and interrupting rotations between a synchronous shaft proximal end 352 a and a synchronous shaft front end 352 b and a brake section for stopping unnecessary movements of the synchronous shaft front end 352 b when it is released. A timing pulley 362 is disposed at the front end of the synchronous shaft 352 and is coupled to the timing pulley 142 attached to the spindle shaft 124 via the timing belts 144 .

In the above structure, when a main motor 46 is started, the twine introducer 6 is rotated by rotations of a main transmission pulley 74 , an auxiliary transmission pulley 48 , a counter pulley 49 , a V-belt 57 , a pulley 4 , a small number wheel 5 , a small number wheel 9 , a small gear 10 and a small gear 7 rotated.

On the other hand, coaxially mounted on the Zählerriemenrad 49 sprocket is rotated together with the Zählerriemenrad 49 350 a Vorderseitenhal ter 122 and a coil 126 are rotated, that is, the Drähschärbaum F is Dre relationships of the chain 356, the sprocket 354, the synchronous shaft 352, the Zeitge bungsriemenrades 262 , timing belt 144 , Zeitungsriemenra des 142 and spindle shaft 124 rotated.

The rotation of the yarn introducer 6 and the rotation of the rotary warping arm F are mechanically synchronized since they are rotated by the main motor 46 via the coaxially mounted counter pulley 49 and the sprocket 354 .

In other words, the components for driving the yarn insertion device 6 (including the main motor 46 , the belt wheels 47 , 48 , 49 etc.) and the spin delwelle 124 of the rotary warping beam F are coupled in the same ratio via the synchronous shaft 352 , so that the yarn insertion device 6 can be rotated synchronously with the rotary skiving boom F

352, the transmission and interruption of rotations between the Synchronwel lenproximalende a and the synchronous shaft front end 352 b, the syn-synchronous rotations ie of the two, one can on and off by turning on and off an attached in a suitable position of the synchronous shaft 352 associated coupling means of the clutch brake unit 360 , and unnecessary movements of the synchronous shaft front end 352 b when released as a result of the interruption of the transmission of the rotation can be braked using the brake portion of the clutch brake unit 360 .

If a plurality of yarns are warmed simultaneously with the rotary warping arm F, the synchronous shaft proximal end 352 a is connected via the coupling device to the synchronous shaft front end 352 b in order to enable synchronous operation of the yarn introducing device 6 and of the rotating warping arm F.

If, on the other hand, a single yarn is warmed with the rotary warping arm F, the synchronous shaft proximal end 352 a is decoupled from the synchronous shaft front end 352 b by the coupling device in order to prevent transmission of the rotation of the former to the latter, and the latter is stopped by the braking device to avoid unnecessary movements. In this way, the rotary warping arm F can be easily switched with the clutch brake unit 360 between the simultaneous multiple yarn warping and the single yarn warping.

Whether the rotating warp beam F is used in a rotating state (simultaneous multiple warping) or a stationary (out of service) state (single thread warping) is automatically determined according to previously set pattern data (thread sequence), and the rotating state and the stationary (out of operating state) of the rotating warping arm F are used alternately chosen. This process is described in more detail with reference to FIG. 21. Fig. 21 is a selective diagram of the rotary warping arm F between the Si multanfachfiachgarnschärschen and the single yarn warping flow chart.

The electronically controlled pattern warping machine W is turned on, and a warping state is input from the program setting unit 78 to supply the control 79 with pattern data with which the warping is performed. Then, a start switch is turned on to a warp selection control section in the controller 79 to select the simultaneous multiple yarn warping (bring the rotary warping arm F into the twist state) or the single yarn warping (bring the twist warping arm F into the stationary or non-operational state).

If the simultaneous multiple yarn warping is selected, a plurality of yarns are wound around the warping drum A at the same time by a plurality of yarn insertion devices of the rotary warping arm F. Yarn count 22 is counted and warp selection is performed again when the count reaches a predetermined number of pattern yarns (or a predetermined number of plain yarns).

If the individual yarn warping is selected, a single yarn is wound around the warping drum A from a plurality of yarn insertion devices of the rotary warping arm F. The yarn count 22 is counted and the warp selection is performed again when the count reaches a predetermined pattern yarn number (or a predetermined single yarn number).

In this way, the pattern warping is carried out according to the above pattern data (thread order) by alternately selecting the simul tan multiple yarn warping and single yarn warping. If necessary Number of yarns around the warping drum A becomes the pattern ration ended.

When the Simultanmehrfachgarnschärung with two or more yarns or the Einzelgarnschärung is performed with only one yarn, the above-mentioned he endless conveyor belt 500 or the conventional transport belts 17 controls ge with respect to a movement distance corresponding to the Schärgarnzahl. In particular, the movement distance of the conveyor belts 500 is increased in the simultaneous multiple yarn warping compared to the single yarn warping, in such a way that the warping density remains essentially the same, even if the number of warmed yarns varies.

The operations performed by the above structure are described below. Fig. 22 illustrates an example of a vertical Garndesigns that can be warped by the electronically controlled sample warper having the rotary creel F with the Garnwechselfunktion the invention according to.

The following is the procedure of warping the illustrated vertical yarn signs.

The vertical yarn design shown in Fig. 22 is produced by repeating a repetition pattern of 442 yarns ten times to achieve a warp width of 200 cm and a total number of yarns of 4,220. The clarification is started from the left end in FIG. 22 and ended at the right end in FIG. 22.

For the repetition pattern from FIG. 22, the rotary warping arm F can be operated in the following manner. For the leftmost area with a total of 200 yarns with repetitions of alternating two red yarns and two white yarns, eight yarns can be warmed at the same time, so that the rotating warp beam F is driven in a synchronous operating mode. In the following area of ten red yarns, the area of two white yarns and the area of ten red yarns, the yarns are one by one warmed so that the rotary warping arm F is released from the simultaneous operating mode in a predetermined position. Then in the next area a total of 200 yarns with repetitions of alternating two red yarns and two white yarns in turn eight yarns are simultaneously warmed so that the rotary warping arm F is driven in synchronous mode.

First, the warping design is entered into the controller 79 via a special program setting device or a PC, and then the warping conditions including warping width, total number of yarns to be warped and warping length are entered.

Next, four red yarns and four white yarns are prepared and applied to the spools 126 of the rotary warp beam F with predetermined numbers. Namely, a red yarn 22 a is applied to a spool 126 a (No. 1); a red yarn 22 b on a spool 126 b (No. 2); a white yarn 22 c on a spool 126 c (No. 3); a white yarn 22 d on a bobbin 126 d (No. 4); a red yarn 22 e on a bobbin 126 e (No. 5); a red yarn 22 f on a spool 126 f (No. 6); a 22 g white yarn on a bobbin 126 g (No. 7); and a white yarn for 22 hours on a bobbin 126 hours (No. 8). Then, each of the yarns is threaded through the yarn retainer 120 , the yarn break sensor 121, and the yarn return device 118 , which correspond thereto.

Then, the yarns are collectively attached to the yarn fixing member E provided on the back of the yarn selection guide 27 which is arranged in front of the base Y. Since the yarn fastening member E has a magnet, the fastening is easy.

• 1. The red yarn 22 a applied to the No. 1 spool 126 a of the rotary warping arm F is accommodated in a No. 1 yarn selection guide 27 a.

• 8. The white yarn 22 h applied to the No. 8 bobbin 126 h of the rotary warping arm F is accommodated in a No. 8 yarn selection guide 27 h.
• 9. When a start switch is turned on, it is determined from a command of the controller 79 whether the rotary warping arm F is to be put into a synchronous operating mode or a fixed operating mode (it is true in the pattern from FIG. 22 that the rotating warping arm F is set into the synchronous operating mode should). Then the yarn introducer starts rotating at a low speed.
• 10. If a no. 1 yarn introduction means 6 a a predetermined selection position is reached, the yarn selection guide pivots 27 a for supplying the no. 1 yarn introduction means 6a to the yarn 22 a (red yarn).
• 11. When a No. 2 yarn insertion device 6 b reaches a predetermined selection position, the yarn selection guide 27 b pivots to supply the No. 2 yarn insertion device 6 b with the yarn 22 b (red yarn).
