Description

The present invention relates to a method for winding a plurality of yarns around a plurality of bobbins as described in the superordinate concept part of claim 1 and to an apparatus according to the superordinate concept part of claim 9 for carrying out this method. .

  A recent trend is to produce synthetic fiber yarns by spinning multiple yarns from one polymer melt in parallel in one spinning section and then winding them around multiple bobbins. Accordingly, it is known to spin 10, 12, 16, or more yarns in parallel and simultaneously wind them onto multiple bobbins. In this case, the yarn is wound in a winder. In this winder, a plurality of bobbins are held by one bobbin spindle and wound. Such a winder requires a correspondingly long bobbin spindle when the bobbin width is large and the number of yarns is large. Accordingly, a new concept has been developed in which a plurality of yarns are simultaneously wound on a bobbin by two bobbin spindles arranged in parallel with each other. A method and apparatus of this type are known from WO 03/068648.

  In the known method and the known apparatus, a plurality of yarns are simultaneously wound around a plurality of bobbins on two bobbin spindles arranged side by side. For this purpose, each of the plurality of bobbin spindles is driven by one spindle driving device. Each bobbin spindle is associated with one of two pressure rollers, and each of these pressure rollers is held movably in the radial direction with respect to the bobbin spindle via one oscillator. During the operation of winding the plurality of yarns around the plurality of bobbins, the pressure roller contacts the outer peripheral surfaces of the plurality of bobbins. In this case, the position of both the pressure roller and the bobbin spindle can be changed as the bobbin diameter increases. A further degree of freedom is obtained by the fact that the pressure-bonding roller held movably is additionally configured to be able to travel toward the bobbin spindle in the radial direction by one carriage. In addition, considering that a plurality of yarns are wound around a plurality of bobbins at a constant winding speed, it is necessary to drive the plurality of bobbins at the same peripheral speed as possible by the bobbin spindle. However, the large degree of freedom necessarily results in the bobbins of the two bobbin spindles having different bobbin structures.

  According to German Offenlegungsschrift 4018095, the rotational speed of the bobbin spindle is controlled in such a way that the peripheral speed is controlled to obtain a constant value in relation to the rotational speed of the pressure roller. Methods for winding a plurality of yarns on a bobbin spindle are known. However, in this manner, controlling the gradually increasing bobbin peripheral speed at each bobbin spindle will inevitably result in different adjustments and windings based on the variety of degrees of freedom of movement. . Thus, the known methods and known devices according to the prior art have the disadvantage that bobbins having different bobbin structures are formed on each bobbin spindle. Therefore, based on the deviation of the peripheral speeds of the plurality of bobbins, a yarn tension that must be changed directly during the winding operation is generated.

  The object of the present invention is to improve the method and the device of the type mentioned at the outset so that a substantially uniform bobbin can be wound on two bobbin spindles simultaneously with a plurality of yarns.

  Another object of the present invention is to make a plurality of yarns of a yarn group to be wound to have the same yarn tension as much as possible by winding.

This problem has been solved according to the invention by a method having the features of claim 1 and an apparatus having the features of claim 9 .

  Advantageous embodiments of the invention are defined by the features described in the dependent claims and combinations thereof.

  In particular, according to the present invention, the change in the driving rotational speed of the bobbin spindle during the bobbin winding operation is controlled by the common adjustment circuit. As a result, the drive rotation speed of the plurality of bobbin spindles is changed synchronously. The bobbin spindle drive is controlled simultaneously. For this purpose, first the rotational speed of one of the pressure rollers is detected. The controller rotates the driving speed of the bobbin spindles together or together so that the detected rotational speed of the pressure roller is maintained substantially constant in relation to the rotational speed measured by the pressure roller each time. (Kollektive) can be changed. This automatically shifts the second pressure roller not connected to the adjustment circuit to the same state as the pressure roller not monitored by the sensor.

  The device according to the invention for carrying out the method according to the invention has one speed sensor on one pressure roller, correspondingly arranged for detecting the rotational speed of this pressure roller. The rotation speed sensor is connected to the spindle driving device of the bobbin spindle by a control device with one control circuit. Thereby, the sensor signals are used to control the two spindle drives in an advantageous manner.

  In order to be able to drive the two bobbin spindles at the same rotational speed as possible and thus at the same peripheral speed of the bobbin, according to an advantageous embodiment of the invention, the bobbin spindles are driven synchronously, Be controlled. For this purpose, the spindle drive is advantageously formed by two synchronous motors and a controller, in which case the controller is connected to the controller. This embodiment is particularly characterized by the flexibility of the arrangement of a plurality of pressure rollers and bobbin spindles. Therefore, the pressure roller and the bobbin spindle can be arranged side by side in a pair, or arranged one above the other. By detecting changes in the rotational speed of one pair of spindles and pressure rollers arranged in a paired fashion, the synchronous drive of the bobbin spindle can simultaneously perform control adjustments in the undetected pair. .

  When a thread is wound around the outer peripheral surface of the bobbin and installed, a slip may occur between the outer peripheral surface of the bobbin and the outer peripheral surface of the pressure roller. In order to avoid such slip occurrence in the two pressure rollers, according to an embodiment of the present invention, the pressure rollers are mechanically or electrically connected to each other so that the two pressure rollers rotate at the same rotational speed. ing. For the connection, the pressure rollers are connected to each other by means of transmission. In order to adapt the number of rotations of the two pressure rollers, the transmission means may be configured mechanically or electrically.

  In this case, the pressure roller is additionally driven in the opposite direction of rotation by an external drive, which is particularly advantageous when exchanging bobbins. However, in an advantageous manner, an external drive device for the pressure roller is suitable for creating a predetermined load ratio between the driven bobbin and the pressure roller. Therefore, the external driving device of the pressure roller is designed such that a component that always advances or a component that brakes acts on the outer peripheral surface of the bobbin. By setting the load ratio, the yarn tension of the wound yarn can be influenced in an advantageous manner. This is because the occurrence of a predetermined slip between the pressure roller and the bobbin can be adjusted.

  Since the external driving device of the pressure roller is suitable for driving the bobbin spindle by friction, the bobbin driving device for directly driving the bobbin spindle can be omitted.

  In addition, as the bobbin diameter increases, a superimposed displacement movement between the bobbin spindle and the pressure roller is performed. Such displacement movements can be carried out individually or in a collective manner, in which case basically no contact is lost between the pressure roller and the outer peripheral surface of the bobbin. Controllability to maintain contact is obtained in an advantageous manner according to an embodiment of the invention by each bobbin spindle being driven by an asynchronous motor. The asynchronous motor is driven in the same frequency range based on the load ratio defined by the external drive device for the pressure roller. Thereby, by aligning the operating state of the asynchronous motor, a defective position that causes an incorrect contact between the pressure roller and the bobbin spindle is detected. In response, a control signal is generated that implements the correction of the displacement motion.

  The displacement movement can be carried out in a simple manner so that a plurality of pressure rollers are commonly guided by a movable holder during the winding operation. This causes a similar adjustment of the pressure roller at the two windings.

  However, it is also possible to guide the pressure rollers so as to move towards the bobbin in the radial direction independently of each other. In this case, the pressure roller is held in an advantageous manner by a movable rocker. This rocking body is held in a machine casing or in a movable holder so as to be able to turn independently of each other.

  However, it is also possible in principle for a plurality of pressure rollers to be held stationary and for the displacement movement to be carried out exclusively by the bobbin spindle. For this purpose, each bobbin spindle is preferably guided synchronously by two movable spindle supports.

  However, it is also possible for the displacement movement between the pressure roller and the bobbin spindle to increase the bobbin by the movement of the pressure roller and by the movement of the bobbin spindle. In addition, by using a movable bobbin support configured as a bobbin revolver, a second bobbin spindle is provided in each winding section so that the two bobbin spindles can be moved alternately to the winding area and the exchange area. The bobbin spindle can be held.

  In the following, the method according to the invention will be described in detail with the aid of the device according to the invention according to several illustrated embodiments.

FIG. 1 shows a front view of a first embodiment of a device according to the invention for carrying out the method according to the invention,
Figure 2 is a schematic view from the back,
3, 4 and 5 are schematic views of another embodiment of the apparatus according to the invention for carrying out the method according to the invention.

  1 and 2 show a first embodiment of the device according to the invention for carrying out the method according to the invention. In this case, FIG. 1 shows a front view, and FIG. 2 shows a view of the embodiment from the back.

  The configuration of the illustrated embodiment will be described first with reference to FIG.

  The device of the invention according to the illustrated embodiment has two windings 29.1 and 29.2. These winding portions are formed side by side in one machine frame 12. In this case, the winding portions 29.1 and 29.2 are configured to be mirror-symmetric with respect to a central left-right symmetry plane. The right winding 29.1 consists of a spindle support 10.1 that is rotatably supported in the machine frame 12. The spindle support 10.1 holds a first protruding bobbin spindle 7.1 and a second protruding bobbin spindle 11.1 which is arranged 180 ° away from this. In this case, the first bobbin spindle 7.1 is in the operating position for winding one or more yarns. The second bobbin spindle 11.1 is in an exchange position for exchanging the full bobbin with an empty bobbin winding.

  A second spindle support 10.2 arranged in the same plane or a shifted plane is provided in the machine frame 12 in the second winding part 29.2 in a mirror image symmetry with respect to the spindle support 10.1. Is retained. The spindle support 10.2 supports the protruding bobbin spindles 7.2 and 11.2. In the operating state shown, the bobbin spindle 7.2 is in the operating position and the bobbin spindle 11.1 is in the replacement position.

  In front of each spindle support 10.1 and 10.2, one pressure roller 6.1 and 6.2 is arranged in the yarn path, respectively. In this case, in order to wind the yarn 1.1 around the bobbin 9.1, the pressure roller 6.1 cooperates with the bobbin spindle 7.1 in the winding part 29.1. During winding of the yarn 1.1, the pressure roller 6.1 presses against the outer peripheral surface of the bobbin 9.1 to be wound.

  Correspondingly, in the winding part 29.1, the pressure roller 6.2 moves the bobbin spindle in the operating position (in the illustrated embodiment in order to wind the second thread 1.2 onto the bobbin 9.2). Cooperate with 7.2). Also in this case, the pressure roller 6.2 is pressure-bonded to the outer peripheral surface of the bobbin 9.2 to be wound.

  The pressure rollers 6.1 and 6.2 are rotatably supported on the holder 3. The holder 13 supports a traverse device (traverse device) 4 disposed in front of the pressure rollers 6.1 and 6.2. The traversing device 4 is arranged in a central plane between the winding sections 29, 1 and 29.2, and one traversing apparatus 5.1 and 5 for each winding section 29.1 and 29.2. .2 and these traversing devices 5.1 and 5.2 cause the supplied yarns 1.1 and 1.2 to reciprocate within the traversing stroke. The traversing device 4 can be constituted by a reversible grooved drum (Kehrgewindewelle), for example. This reversible grooved drum has one or more grooves on its outer peripheral surface for guiding the traverse yarn guides 5.1 and 5.2.

  A thread guide support 3 is provided on the upper side of the holder 13, and the thread guide support 3 supports the thread guides 2.1 and 2.2. In this case, the yarn guide 2.1 is arranged corresponding to the winding part 29.1, and the yarn guide 2.2 is arranged corresponding to the winding part 29.2.

  The holder 13 is configured to be movable in the vertical direction by a carriage 15 and carriage guides 14.1, 14.2. In this case, the carriage 15 is held in the carriage guides 14.1 and 14.2 by the two force generators 16.1 and 16.2, and the pressure rollers 6.1 and 62. Are respectively applied to the bobbins 9.1 and 9.2 during the winding operation of the yarns 1.1 and 1.2 with a predetermined crimping force.

  In the embodiment shown in FIG. 1, one thread 1.1 and 1.2 is wound on bobbins 9.1 and 9.2, respectively, at winding sections 29.1 and 29.2. However, basically such a device is provided for winding a plurality of yarns around a plurality of bobbins simultaneously. For this purpose, a plurality of bobbin winding tubes 8.1 and 8.2 fitted on the bobbin spindles 7.1 and 7.2 are held one after the other. In this case, eight, ten or more bobbin windings can be held simultaneously by the bobbin spindle 7.1 and the bobbin spindle 7.2. In this case, since the bobbin spindle, the pressure roller, and the traversing device have correspondingly projected lengths, a plurality of yarns can be simultaneously wound in parallel with each other.

  However, for the method according to the present invention, it is important whether one thread (as shown) or a plurality of threads are wound on the bobbin in the winding sections 29.1 and 29.2, respectively. Absent.

  In order to further explain the first embodiment, the bobbin spindle 71. And 7.2 drive stations are described below with reference to FIG. For the sake of clarity, FIG. 2 shows schematically a rear view of only the device parts of the windings 29.1 and 29.2 necessary for carrying out the method according to the invention. .

  A bobbin spindle 7.2 is connected to the spindle drive 23.2 via the spindle end 22.2 in the winding part 29.2. A controller 24.2 is arranged corresponding to the spindle driving device 23.2, and this control device 24.2 is connected to the host control device 21. In this case, the bobbin 9.2 taken up by the bobbin spindle 7.2 is indicated by a broken line. On the outer peripheral surface of the bobbin 9.2, a pressure roller 6.2 supported so as to be freely rotatable is in contact, and this pressure roller is also indicated by a broken line. The pressure roller 6.2 has a roller end 18.2. A rotation speed sensor 20 is arranged corresponding to the roller end 18.2, and the rotation speed of the pressure roller 6.2 is detected by the rotation speed sensor 20. The rotation speed sensor 29 is connected to the control device 21.

In another winding part 29.1, the bobbin spindle 7.1 is connected to the spindle drive 23.1 at the spindle end 22.1. The spindle drive 23.1 is associated with a controller 24.1, which is likewise connected to the controller 21. A bobbin 9.1 which is formed on the outer peripheral surface of the bobbin spindle 7.1 and is also indicated by a broken line is in contact with the second pressure roller 6.1. In this case, the pressure roller 6.1 of the second winding part 29.1 has one roller end 18.1 that is connected to the other winding part 29 . 2 is connected to the pressure roller 6.2. In this embodiment, since the transmission means 19 is mechanically constituted by a belt or a chain, the two winding sections and the two pressure rollers 6.1 and 6.2 rotate at the same rotational speed.

  Next, it will be described in more detail with reference to FIGS. In order to wind the yarn 1.1 at the winding part 29.1, the bobbin spindle 7.1 is driven in the clockwise direction (FIG. 1) by the spindle drive 23.1. The pressure roller 6.1 is in contact with the outer peripheral surface of the bobbin 9.1 to be wound, and is driven in the reverse direction through friction.

  In the winding part 29.2, the bobbin spindle 7.2 is driven counterclockwise (FIG. 1) by the spindle driving device 23.2 in order to wind the yarn 1.2 around the bobbin 9.2. . In this case, the pressure roller 6.2 rotates clockwise on the outer peripheral surface of the bobbin 9.2 at a rotation speed corresponding to the pressure roller 6.1. Transmission of rotation between the pressure rollers 6.1 and 6.2 is performed by the transmission means 19. Since the two windings 29.1 and 29.2 are wound synchronously, similarly shaped bobbins 9.1 and 9.2 are formed in each of the bobbin spindles 7.1 and 7.2, respectively. The

  In order to maintain a constant winding speed of the yarns 1.1 and 1.2, the rotational speed of the pressure roller 6.2 is continuously detected by the rotational speed sensor 20 and supplied to the control device 21. In the control device 21, the target rotational speed of the pressure roller 6.2 is stored. As soon as an unacceptable deviation between the detected actual rotational speed of the pressure roller 6.2 and the stored target rotational speed of the pressure roller 6.2 is detected, a control signal is transmitted to the controller 24. .1 and 24.2. The controllers 24.1 and 24.2 change the drive rotation speed of the spindle drive devices 23.1 and 23.2 so that the actual rotation speed changed for the pressure roller 6.2 is obtained. This adjusts the constant peripheral speed of the bobbins 9.1 and 9.2 during the entire winding operation of the yarns 1.1 and 1.2. In this case, the spindle drives 23.1 and 23.2 are formed in an advantageous manner by asynchronous motors. Since the rotational speed feedback of the asynchronous motor takes place in an advantageous manner by multiplex switching, the control device only needs one input.

  During the winding of the yarns 1.1 and 1.2, the necessary displacement movement based on the increase of the bobbins 9.1 and 9.2 is also movable in this embodiment by the holding 13 held movable. Can also be implemented with bobbin spindles 7.1 and 7.2 held in Due to the rigid arrangement of the pressure rollers 6.1 and 6.2 in the holder 13, the bobbins 9.1 and 9.2 are increased synchronously by the movement of the carriage 15.

  Since the rotational drives of the bobbin supports 10.1 and 10.2, not shown, are preferably driven synchronously in order to carry out the displacement movement, for example, two spindle supports 10, 1 and 10.2 are connected to each other by transmission means and actuated by a rotary drive.

  FIG. 3 schematically shows another embodiment for controlling the bobbin spindle of two windings according to the method according to the invention. The embodiment shown in FIG. 3 is configured almost the same as the embodiment shown in FIGS. 1 and 2, and therefore only the differences will be described below. In the winding part 29.1, the bobbin spindle 7.1 and the pressure roller 6.1 cooperate to wind up the bobbin 9.1. The pressure roller 6.1 is supported so as to be freely rotatable. In this case, the rotation speed sensor 20 is arranged corresponding to the roller end 18.1. The rotation speed sensor 20 is connected to the spindle drive devices 23.1 and 23.1 by a control device 21 leading to the adjustment circuit. For this purpose, a controller 24 is arranged corresponding to the spindle drive devices 23.1 and 23.2. The spindle driving devices 23.1 and 23.2 are each formed by a synchronous motor. The controller 24 is connected to the control device 21.

  In the second winding part 29.2, the bobbin spindle 7.2 and the pressure roller 6.2 cooperate.

  In this embodiment, the two pressure rollers 6.1 and 6.2 are located on the outer periphery of the bobbins 9.1 and 9.2 to be wound. Bobbins 9.1 and 9.2 are driven by bobbin spindles 7.1 and 7.2, respectively, and by spindle drives 23.1 and 23.1 connected thereto. As a result, the rotational speeds of the pressure-bonding rollers 6.1 and 6.2 are adjusted to the respective bobbins 9.1 and 92. It is defined by the peripheral speed. The rotational speed of the pressure roller 6.1 is detected by the rotational speed sensor 20 and supplied to the control device 21. In the control device 21, the actual value is compared with the target value. When an unacceptable difference between the actual value and the target value occurs, a control signal is formed in the control device 21 and this control signal is supplied to the controller 24. By means of the controller 24, the spindle drives 23.1 and 23.2 are driven with the changed driving speed. The change in the driving rotational speed is performed synchronously in the two winding sections 29.1 and 29.2. In this case, the change in the peripheral speed and consequently the rotational speed of the pressure roller 6.1 in the spinning section 29.1. A change is produced and signaled via the rotational speed sensor of the control device 21. Unlike the previous embodiment, the two pressure rollers 6.1 and 6.2 of the adjacent winding sections 29.1, 29.2 are freely rotatable independently of each other. This provides a high degree of freedom with respect to the arrangement of the structural groups of the two windings, and these structural groups are not limited to horizontal arrangements.

  FIGS. 4 and 5 schematically show another embodiment of the device according to the invention for carrying out the method according to the invention, in which case the two embodiments are shown in FIG. It is almost the same as the example. Hereinafter, only points different from the embodiment of FIG. 1 will be described.

  In the embodiment shown in FIG. 4, the pressure rollers 6.1 and 6.2 of the two winding portions 29.1 and 29.2 are driven by the external driving device 25. In this case, the external drive device 25 is formed by a belt transmission device 26 and an electric motor 28, and a controller 27 is disposed corresponding to the electric motor 28. The controller 27 is connected to the control device 21. By means of the external drive device 25, the pressure rollers 6.1 and 6.2 are driven in opposite directions to each other in the rotational direction necessary for winding.

  The driving of the bobbin spindles 7.1 and 7.2 and the adjustment of the driving rotational speed of the bobbin spindle are performed in the same manner as in the embodiment shown in FIG. Therefore, for this, reference is made to the description of the embodiment shown in FIG. 2, in which case the windings 29.1 and 29.2 are exchanged for monitoring their rotational speed.

  The external drive device 25 adjusts the load ratio between the drive of the drive rollers 6.1 and 6.2 and the drive of the bobbin spindles 7.1 and 7.2. As a result, the pressure rollers 6.1 and 6.2 apply a driving action and a braking action to the outer peripheral surfaces of the bobbins 9.1 and 9.2. The load ratio is given by the control device 21. When the displacement movement of the bobbin spindle or the pressure roller is performed in a superimposed manner, the actual load ratio is additionally adjusted in the control device 21 in order to avoid an erroneous contact operation. For this purpose, the operating state, in particular the drive frequency of the spindle drive 23.1, 23.1, is supplied to the control device 21 via the controllers 24.1, 24.2. For this purpose, the spindle drives 23.1 and 23.2 are configured as asynchronous motors. When the two winding parts 29.1, 29.2 are wound with the adjustment, there is no significant difference in the operating state of the spindle driving devices 23.1, 23.2. If one drive has a different drive frequency than the other drive, correction of the displacement movement is carried out, so that in some cases an incorrect contact state is formed again.

  The embodiment shown in FIG. 5 is almost the same as the embodiment shown in FIG. In this case, the pressure rollers 6.1 and 6.2 are driven by the external driving device 25. In this case, the external drive device 25 is formed by two electric motors 28.1, 28.2 and a controller 27 arranged corresponding to these electric motors. As a result, the pressure-bonding rollers 6.1 and 6.2 can be electrically connected to the external driving device 25.

  The method and apparatus according to the present invention is not limited to the individual equipment arrangement shown in FIG. Basically, in particular, a plurality of pressure rollers are held movably in the radial direction with respect to the bobbin spindle by vibration at a plurality of winding portions. The holding of the bobbin spindle and the pressure roller is only important for carrying out the displacement movement mainly. Regardless of the displacement movement, however, the peripheral speed of the bobbin is always adjusted so that a plurality of yarns are wound with the same winding speed and thus with a substantially constant yarn tension.
