Description

  The present invention is a method for manufacturing a warp for a pattern, wherein at least one yarn is guided around a circumferential surface of a warping drum by a yarn guide device to generate one wound layer group, The present invention relates to a manufacturing method including a step in which a yarn guide device is moved in an axial direction relative to a warping drum at a predetermined angular position at least once per winding layer group in response to a control signal.

  Further, the present invention provides a warp drum, a control device, a rotary drive device that can move around the circumferential surface of the warp drum, and an axial drive device for the warp drum that depends on the control device signal In particular, the present invention relates to a partial warp for warp warp having at least one yarn guide device that is relatively movable in the axial direction and an angular position detection device connected to a control device.

Yarns that will later become pattern warps are guided around the circumference of the warping drum to produce the pattern warp. One technique is to guide each yarn individually around the warping drum.
As another method, there is a method in which a plurality of yarns are guided around the warping drum at the same time. In this case, the plurality of yarns are pulled out from the rotary creel. In order to achieve the required pattern warp length, the yarn must be guided around the warping drum in the form of many winding layers. When the warp drum has a circumferential length of 7 m, for example, if a warp length for a pattern of 700 m is required, 100 winding layers are required for each yarn.

By the way, the yarns cannot be stacked in the radial direction. This is because, when trying to place them in the radial direction, the individual wound layers of each yarn do not stay (cannot be maintained) as they were when they are wound, and are almost upright. This is because the side surface may slide down (collapse).
In such a state, a problem occurs when the pattern warp is later pulled out from the warping drum. In order to eliminate this problem, it is known to shift one or more yarns in the axial direction by a small section in the axial direction of the warping drum during each rotation of the yarn guide device. Thereby, a conical front surface (side surface) is generated at the end of the yarn layer formed on the peripheral surface of the warping drum. If this cone angle (cone tilt angle) is chosen sufficiently shallow (to a small angle), the individual wound layers will no longer slide down.

  By the way, if one yarn is guided around the warping drum to the number of winding layers necessary to obtain a desired warp length, for the next winding layer group, the yarn guide device is used as a new winding layer. The first winding layer of the group has to be returned again to the position of the base of the cone on the warping drum so that it is fed again onto the circumferential surface of the warping drum. For this reason, the yarn guide device must move (move) a relatively large section (distance) in the axial direction of the warping drum within a relatively short time.

By the way, it has been found that problems occur when the operating speed of the warping drum is high. In other words, when the operating speed of the warping drum is high, the yarn layer formed on the peripheral surface of the warping drum may no longer be properly wound, and in such a case, when rewinding, that is, from the warping drum. Problems sometimes arise when pulling out the yarn (see Patent Document 1).
German patent invention No. 10061490.

  An object of the present invention is to provide a pattern warp manufacturing method and a pattern warp partial warper capable of manufacturing a pattern warp at a high operating speed.

  The problem is that in the method of the type pointed out at the beginning, the angular interval between the predetermined angular position at which the yarn guide device is moved in the axial direction and the angular position at which the control signal is generated is warped by the yarn guide device. It is solved by configuring it to be selected depending on the speed of movement around the drum.

Problems that arise when the operating speed of the partial warp for warp warps is high, at least in part, are attributed to the fact that the axial drive of the yarn guide device has a constant inertia. In other words, some of the problems are attributed to the fact that the yarn guide device does not move immediately after receiving the control signal but moves after a certain reaction time.
By the way, when the time point at which the control signal is generated at high speed is advanced, that is, when the yarn guide device still has a certain angular interval with respect to the angular position where the movement should be originally started, that is, the angle If the control signal is already generated at the angular position on the near side with respect to the position, in this case, a configuration in consideration of the inertia of the yarn guide device can be realized. That is, at the time of high speed, the start position of the movement of the yarn guide device is earlier than that at the time of low speed (angular position). In this way, it is achieved that the movement of the yarn guide device can always be started at a predetermined angular position despite the inertia. In this case, the required angular position can be set with relatively high accuracy.

Preferably, said angular spacing is selected such that the time required for the yarn guide device to take account of inertia is constant regardless of speed. In other words, the angular interval is selected so that the time from the generation of the control signal to the start of the movement of the yarn guide device using the angular interval is constant regardless of the moving speed of the yarn guide device. It is to be done. The problem does not necessarily need to be “constant” in the mathematical sense (strict sense).
If the reaction time, that is, the time between the generation of the control signal and the start of the movement of the yarn guide device and the rotational speed of the yarn guide device are known, the angle interval is calculated by simple division from both values. With it, the angular position at which the control signal must be generated can be determined so that the yarn guide device moves at the required angular position.

  Preferably, the yarn guide device is configured to be driven by a stepping motor. The stepping motor makes it possible to obtain high accuracy when controlling the axial position of the yarn guide device. Depending on the inertia present in the stepping motor, the stepping motor responds to the generation of the control signal, but this inertia can be offset by the above-mentioned “early control signal generation”.

  Preferably, in order to move the yarn guide device, the lever is configured to swing around an axis extending parallel to the radial direction of the warping drum. That is, the stepping motor can be configured as a rotary motor, which contributes to simplifying the structure of the motor and keeping costs low. In that case, the yarn guide device may be disposed at the tip of the lever, for example. By the way, if the lever swings around an axis extending parallel to the radial direction of the warping drum, an appropriate axial movement of the yarn guide device occurs. In addition, the lever swing angle can be taken into account when the control signal is generated. That is, with the movement of the yarn guide device in the axial direction, displacement of the yarn guide device, for example, the eyelet (piglet) in the circumferential direction also occurs. Even if this movement in the circumferential direction is not excessively large, this movement in the circumferential direction may be important for the precise control of the yarn guide device. That is, when calculating the angular interval at which the control signal must be generated earlier, the control signal starts from the absolute position of the yarn guide device in the circumferential direction.

  Preferably, the yarn guide device is withdrawn from the group of winding layers in the direction of the first end of the warping drum at least once in at least one winding layer, and at least once in at least one winding layer. Is drawn from the wound layer group in the direction of the second end. Increasing the accuracy when controlling the movement of the yarn guide device in the axial direction then provides additional possibilities for moving the yarn guide device. In addition to the return movement of the thread guide device required to return a single thread from the radially outer end of the cone to the inner start of the cone, additional movement possibilities are obtained. For example, it is possible to facilitate insertion of the yarn into the dividing rod by movement in two directions opposite to each other in the axial direction at the start and end of the handle warp. The dividing rod has a capture device, but the speed of operation of this capture device is limited. However, due to the possibility of the additional movement of the yarn guide device, it is not necessary to rely solely on the performance of the catch device.

In so doing, preferably the yarn guide device is guided by a dividing rod in front of the catching device as it moves in the first end direction of the warping drum, and deviating behind the catching device as it moves in the second end direction. Guided by the rod and configured to operate the catching device in relation to the movement of the yarn guide device.
With such a configuration, it is possible to achieve a much higher operating speed than was possible in the past by the cooperation of the movement of the yarn guide device and the movement of the catching device. The movement of the yarn guide device is additionally started depending on the operating speed of the partial warp for the warp yarn, that is, the rotational speed of the yarn guide device, so that the capture device for the dividing rod can always be properly captured. Is certain.

  In this case, it is preferable that the yarn guide device is configured to be moved to the fixed end position in at least one movement outward from the wound layer group. This simplifies motion control for the yarn guide device.

  It is also advantageous if the speed of movement of the yarn guide device in the axial direction is substantially the same as the speed of movement of the yarn guide device around the circumferential surface of the warping drum. When the rotational speed is high, the yarn guide device moves in the axial direction correspondingly faster than when the rotational speed is low. Correspondingly, the movement of the yarn guide device in the axial direction is started and finished at the required angular position in the circumferential direction of the warp drum, irrespective of the rotational speed of the yarn guide device.

  In the partial warper for the handle warp of the type pointed out at the beginning, the subject has a speed calculating device for rotational motion of the yarn guide device, and this speed calculating device is connected to the signal generating device, This is solved by having a delay element having a variable delay in the signal generator.

  As described above, with this configuration, in consideration of the “inertia” of the axial drive device, the axial movement of the yarn guide device is actuated so that the movement of the yarn guide device starts at a predetermined angular position. These control signals can be generated in time. The delay device calculates the signal generation angle at which the control signal for movement of the yarn guide device is to be generated, depending on the starting angle, for example, passing the zero point. The signal generation angle can be changed depending on the rotational speed of the yarn guide device. That is, the delay can be made variable with respect to the value of the starting angle.

  Preferably, the speed calculation device is connected to an angle detection device and has a differentiating device. The angular position of the yarn guide device is continuously detected anyway, for example via an angle encoder, so that eventually speed information is also obtained. The rotational speed can be calculated relatively easily by differentiating the angular position over a predetermined time.

  Preferably, the yarn guide device has a stepping motor as an axial direction driving device. Using the stepping motor, the position of the yarn guide device in the axial direction can be adjusted relatively accurately.

  In this case, the stepping motor is preferably configured as a rotary motor, and the rotation axis thereof is arranged in parallel with the radial direction of the warping drum. A stepping motor, which is a rotary motor, can be easily controlled and is relatively inexpensive.

  Preferably, an electronic transmission device that can be switched between the rotary drive device and the axial drive device is arranged. This electronic transmission device can be realized by a control device, for example. In that case, for example, the control device controls the stepping motor so that the stepping motor executes a predetermined number of steps for every increment of the advance angle of the yarn guide device in the circumferential direction. If the rotational speed of the yarn guide device is high, these steps must be performed in a shorter time than if the rotational speed is low. This has the advantage that the axial movement of the yarn guide device always starts and ends at the same warp drum position in the circumferential direction irrespective of the rotational speed of the yarn guide device.

  Preferably, the yarn guide device is configured to be able to move spirally around the circumferential surface of the warping drum, and the yarn guide device is configured to be movable beyond the start and end of the spiral. Such an arrangement provides the advantages described above in connection with the method.

  In this case, the dividing rod is preferably arranged parallel to the axis of the warping drum and has one catching device at its end facing the yarn guide device, the yarn guide device protruding in front of the warping drum. It is possible to move to the front of the capturing device for the dividing rod and to the rear of the capturing device for the separating rod retracted from the front of the warping drum. In this case, it is possible to enhance the “capture certainty” in which the yarn guided by the yarn guide device is fed by the catching device onto or under the dividing rod. At the same time, the speed of guiding the yarn guide device around the circumferential surface of the warping drum can be further increased.

  The invention will now be described in conjunction with the drawings on the basis of preferred embodiments.

  1 includes a warping drum 1 as a yarn winding body, and is arranged on the peripheral surface of the warping drum 1 and is conveyed parallel to the axis of the warping drum 1. The warp partial warping machine shown in FIG. The conveying belt 2 extending in the direction is configured to be movable in the direction indicated by the arrow 3 in FIG. The conveyor belt 2 forms a conveyor surface device. Dividing rods 4, 5, 6 arranged parallel to the axis of warping drum 1 can also be referred to as “Leeds rod” or “cutting rod” depending on their functions. Further, another dividing rod can be arranged on the opposite side of the warping drum 1 that cannot be seen in FIG.

  The rotary creel 7 has a rotating body 8 that carries a large number of bobbins 9 and is driven (rotated) by a motor 10.

  A yarn guide 11 is provided at the front end of the warping drum 1, and the yarn 12 drawn out from the bobbin 9 is guided around the peripheral surface of the warping drum 1 using the yarn guide 11. It is configured to be able to. For this reason, the thread guide 11 has an eyelet (eyelet) 13 as a thread guide device, and the thread 12 is passed through the eyelet 13. These eyelets 13 are arranged at the tip of the lever 14 (FIGS. 2 and 3). The lever 14 is rotatable with respect to an arm 16 extending in the radial direction of the warping drum 1 by a servo motor (in this embodiment, for example, a “rotating stepping motor”) 15 as an axial drive device. It is configured. The motor 15 is controlled by the control device 17 so that the eyelet 13 can change its position to the direction indicated by the double-headed arrow 18 in FIG.

  The arm 16 is driven by the rotary creel 7 via a shaft 19. That is, the yarn guide 11 rotates in synchronization with the rotary creel 7.

  A yarn thickness measuring device 20 is disposed in the yarn supply path of the yarn 12. The yarn thickness measuring device 20 has a measuring unit 21, and the measuring unit 21 guides the yarn 12 on a circular path. At that time, the thickness of the yarn 12 can be detected by shadowing the detector 22 by the width dimension depending on the thickness. That is, the yarn thickness measuring device 20 detects the thickness once every time each yarn 12 rotates (refer to the rotation direction 23 in FIG. 2), and the detected thickness of the yarn 12 is sent to the control device 17. introduce.

  Sorting fingers 24, 25, and 26 serving as capturing devices are arranged at the positions of the end portions of the dividing rods 4, 5, and 6 facing the rotary creel 7. The sorting fingers 24 to 26 are arranged so that the yarn is located either on the radially outer side of the dividing rods 4, 5, 6 or on the radially inner side of the dividing rods 4, 5, 6 with respect to the warping drum 1. , Guide the yarn. The sorting fingers 24, 25 and 26 can be used to form a kreuz. The twill is generally required at the beginning and end of the warp so that the yarn can be individualized and the yarn cut on the other. In FIG. 1, three dividing rods 4, 5, 6 are shown. However, a larger number, for example, four dividing rods 4a, 4b, 5a, 5b may be provided as shown in FIG.

  FIG. 4 is a side view showing a schematic configuration of the partial warping machine. The same elements as those in FIG. 1 are denoted by the same reference numerals. However, in FIG. 4, four dividing rods 4a, 4b, 5a, and 5b are shown, and these dividing rods 4a, 4b, 5a, and 5b form a twill at the start and end of the warp. Useful. Each dividing rod 4a, 4b or 5a, 5b is provided with sorting fingers 24a, 24b or 25a, 25b, and these sorting fingers are in the direction indicated by the arrow 27 in both directions as shown for the sorting fingers 24a. It can swing.

  The conveyor belt 2 is wound around a belt pulley 28. In the state illustrated in FIG. 4, the yarn layer 29 has already been formed on the conveyor belt 2. That is, a large number of yarns having a corresponding number of winding layers have already been guided around the warping drum 1.

  When a space is secured again to wind a new yarn after winding one yarn or one yarn group, the yarn layer 29 drives the conveying belt 2 in the warping direction indicated by the arrow 30. It is moved by. The movement of the yarn layer 29 in the warping direction is performed during winding, preferably during winding at a constant speed. However, even when one wound layer group is completed and a new wound layer group is to be started again, the feeding operation in the warping direction can be performed.

  In FIG. 4, it can be visually recognized that the thread layer 29 has a conical front surface 31. A boundary 33 between the thread layer 29 and the wound layer group 32 just finished is indicated by a broken line in FIG. One wound layer group is formed from a large number of wound layers of one or more yarns that cause the required length of the pattern warp to be produced as a whole. The wound layer group 32 is delimited by a conical front face 31 on one side and a boundary 33 indicated by a broken line on the opposite side. When the wound layer group is finished, the front yarn (front side in the warping direction 30) moves from the lower position 34 to the upper position 35, and the rear yarn (rear side in the warping direction 30) It moves from the lower position 36 to the upper position 37. In this case, these yarns are guided by the yarn guide 11 and, more precisely, by the eyelet 13 of the lever 14. The movement of the yarns 12 a and 12 b during winding is caused by an appropriate swinging movement of the lever 14 (see the broken line in FIG. 4). The lever 14 is driven by a motor 15.

  By the way, if one wound layer group is finished, the front yarn must be moved from the upper position 35 to the position 36 below the rear yarn. This is done by a quick return movement of the lever 14. That is, the lever 14 swings from the position “a” at the end of the wound layer group to the position “b” at the start of the new wound layer group. Although only a single lever 14 is shown, it will be obvious to those skilled in the art that all levers perform this action. The lever 14 is controlled to feed the yarn onto the conveyor belt 2 in a state where the yarns are arranged in the warping direction 30.

  As described above, at least one twill is required at each of the start and end of the warp. The front and followers are possible, but will not be discussed in detail below. In order to be able to provide this twill, two dividing rod groups each having two dividing rods 4a, 4b and 5a, 5b are provided. When the juxtaposed yarns are described with serial numbers, the yarn G having an even reference number is fed above the dividing rod 4a, while all other yarns are wound directly into the yarn layer 29. . The yarn U having an odd number is fed in the other dividing rod 4 b above the dividing rod 4 b, and all the other yarns are wound up in the yarn layer 29. The same applies to the other two dividing rods 5a. That is, the even numbered yarn G is fed below the dividing rod 5a, while the odd numbered yarn is wound directly into the yarn layer 29, that is, stays above the dividing rod 5a. The odd numbered yarn U is fed by the dividing rod 5b below the dividing rod 5b, while the other yarns stay above it in the yarn layer 29. In order to be able to perform this yarn sorting, the sorting fingers 24a, 24b, 25a, 25b are moved.

  In addition, however, the lever 14 is swung more than necessary to produce one wound layer group. In order to feed one yarn above the dividing rod 4a or above the dividing rod 4b, the lever 14 swings to a position c, that is, outward from an area necessary for winding the winding layer group. Rocks. That is, the eyelet 13 leaves the spiral trajectory that has been guided around the warping drum 1 until then.

  Similarly, the lever 14 is moved to the position d outside the helix on the rotary creel 7 to guide the yarn 12b to the right side of the sorting fingers 25a, 25b, and naturally the sorting fingers 25a have an even number of arrangements. Only the yarn with the number G is guided along the side, and only the yarn U with the odd reference number is guided along the side with the sorting finger 25b.

  In FIG. 4, at least the position c of the lever 14 can be an end position that can be controlled by the motor 15. Such a configuration simplifies control. The motor 15 is simply moved to the end position in order to reach this position c.

  This is also basically valid for the position d. However, in many cases, in order to guide the yarn by the side of the conveyor belt 2, it is necessary to further swing the lever 14, that is, beyond the position d. This is a reasonable operation when the yarn is removed from the warping process. In that case, the yarn is wound around a core material not shown in detail, and this core material is arranged, for example, in the shaft of the warping drum 1 as known from US Pat.

  It is no longer necessary to rely solely on the motility of the sorting fingers 24a, 24b, 25a, 25b, and the guide of the yarns 12a, 12b before or after the sorting fingers can be controlled by the appropriate movement of the lever 14, so that The operating speed of the warping machine can be increased. That is, the yarn can be guided around the warping drum 1 at a higher speed than previously possible.

  In order to ensure that the yarn is always “trapped” in the individual dividing rods despite the high speed, the movement of the lever 14 is configured to match the rotational speed of the arm 16. This point will be described below with reference to FIGS. In these drawings, the same elements as those in FIGS. 1 to 4 are denoted by the same reference numerals.

The eyelet 13 is moved on the circular orbit 40. Assume that the eyelet 13 is moved by the lever 14 swinging at an angular position 41 shown in FIG. In order to be able to execute this swinging motion, the motor 15 constituted by a rotary stepping motor must be controlled by a control signal from the control device 42. However, the motor 15 has a certain inertia. That is, the motor can respond to this signal with a delay of a short delay time of 4 ms to 6 ms. Therefore, within this time, the eyelet 13 advances through a larger or smaller section depending on the rotational speed of the arm 16. Thus, if this speed is not taken into account, the eyelet 13 will already be in the angular position 43 when the lever 14 begins to move. At the same time, it is not feasible for one of the sorting fingers originally intended to be reached, for example one of the sorting fingers 24a, 24b, 25a, 25b, to be closely approached so that the yarn is properly above or below the dividing rod.
For this reason, the control start point is shifted to the angular position 44 before the angular position 41 so that the lever 14 starts moving when the lever 14 passes through the angular position 41.

  The rotation angle detection device provided for technically realizing this is a converter 45 that rotates integrally with the arm 16 and cooperates, and a predetermined number of pulses are supplied from the converter 45 for each angle increment. Sensor 46. The sensor 46 is connected to an angle encoder 47 as an angle detection device that calculates the actual angle α of the arm 16. The angle encoder 47 itself is connected to a speed calculation device 48, which calculates the angular velocity ω = dα / dt, that is, the angle α is differentiated with respect to time over a predetermined time, and the angular velocity is calculated. obtain.

  The reference angle setting unit 49 sets the reference angle α0. The reference angle α0 can be, for example, the upper vertex of the movement of the arm 16, that is, the angle at which the arm 16 faces vertically upward. Starting from this reference angle α0, an angular position at which the arm 16 must move originally is calculated, and this angular position is, for example, the 200 ° angular position.

  By the way, a delay device 50 is provided, which forms a difference (angle interval) between the reference angle α0 and the generation of a signal for driving the motor 15 at the speed ω. Therefore, the angular velocity ω is supplied to the delay device 50 as data. The larger the angular velocity ω, the faster the signal that drives the motor 15 needs to be generated. For example, when the winding speed is 1200 m / min, the start of the rotational motion is shifted to an angular position of a rotational angle of 194 ° so that the arm 16 can perform a rotational motion about its swing axis at a rotational angle of 200 °.

  The control device 51 shown in FIG. 6 can also be used as an “electronic transmission device”. The stepping motor 15 moves the lever 14 in relatively small angular increments, causing the lever 14 to swing about an axis aligned parallel to the radial direction of the warping drum 1. By the way, a predetermined number of steps of the stepping motor 15 can be assigned to the angle increment that the arm 16 advances when rotating. If the arm 16 rotates slowly, more time is provided for this number of steps than if the arm 16 rotates faster.

  If the movement of the lever 14 is based on the “early control signal generation”, that is, even when the rotational speed of the arm 16 is high, if the movement of the lever 14 is started at an appropriate position, the subsequent movement of the lever 14 will cause Regardless of speed, you can always do the same. That is, when the rotation speed is high, the lever 14 moves more quickly than when the rotation speed is low.

  The method for producing a warp for a pattern and a partial warp for a pattern warp according to the present invention can be used for producing a warp for a pattern and the like.
