Description

  The present invention has two spindle supports arranged in parallel, and these spindle supports are supported in a cantilevered manner so as to be rotatably supported. The winding device according to claim 1, wherein one winding spindle for winding is disposed.

  An apparatus of this type is known from WO 03/06864.

  In this known device, a plurality of yarns are simultaneously wound on a bobbin by two winding spindles arranged in parallel. For this purpose, each take-up spindle is cantilevered on a spindle support and is arranged rotatably. In this case, the winding spindle is driven in the reverse rotation direction by a spindle driving device arranged corresponding to the winding spindle. A yarn supply unit and a traverse member are disposed between the winding spindles. The plurality of yarns are wound around the bobbin in the reverse rotation direction by the plurality of winding spindles, respectively. In order to receive the bobbin, a winding tube is fitted over the winding spindle and tightened. A winding tube of this type has a catch slit at one end region, and the catch slit allows the yarn to be caught at the start of winding and to start winding. When winding a plurality of yarns, a so-called spare yarn is first installed in the area of the catch slit, and this spare yarn is used to tie a yarn end to a yarn start end of another bobbin in a subsequent work process. Used for. In order to form bobbins having the same winding direction in the two winding spindles, it is necessary to hold a plurality of winding tubes on the two winding spindles in different directions. Is wound around the bobbin on the side facing the bearing end of the winding spindle, and the other winding spindle is wound on the bobbin on the side facing the free end of the winding spindle. This adjusts the deviation between the bobbins of the two winding spindles, so that different yarn feeds can be performed. In particular, when the traversing yarn guide arranged corresponding to the winding spindle uses a traversing member that is simultaneously driven by one driving means, different traversing strokes are formed based on the displacement of the bobbin with respect to each winding spindle. Problem occurs. This requires the provision of additional thread guides and auxiliary devices in order to form identically shaped bobbins on the two winding spindles.

  Accordingly, an object of the present invention is to improve a winding device of the type described at the beginning so that a bobbin having the same winding direction can be wound in a simple form in a guide element arranged in a mirror-like manner. Is to do.

  According to the invention, this problem has been solved by a winding device having the features described in claim 1.

  Advantageous embodiments of the invention are obtained by the features described in the dependent claims and combinations of these features.

  The present invention is based on the fact that the bobbin is held asymmetrically on the winding tube on the basis of the fact that the preliminary yarn is held on one end face, that is, the axial direction between the center of the bobbin and the center of the winding tube. This is based on the fact that the alignment of the preliminary yarn with respect to the winding spindle defines the position of the bobbin on the winding spindle. The winding device according to the invention departs from the idea that the winding loads are the same in the two winding spindles. For this purpose, the bearing end of the take-up spindle is provided with one abutment surface for the end of the winding tube, and this abutment surface is formed by two stopper surfaces adjacent to each other. Is arranged. Since a predetermined distance is maintained between these two stopper surfaces, the winding tube is relatively held by the winding spindle at different axial positions. In this case, it is not important whether the winding device has only one winding section or a plurality of winding sections in each winding spindle. In the case where a plurality of winding portions are formed, the plurality of winding tubes are fitted in a single column shape in succession to the winding spindle, so that the contact surfaces at the bearing end portions of the winding spindle are respectively Defines the relative position of the winding tube on the winding spindle.

In order to maintain the same yarn supply in the yarn supply section, in particular the traversing member, according to an embodiment of the invention, in an advantageous manner, the spacing between the stopper faces is 2 when the same winding tube is used. The bobbin ends of the bobbins wound on the winding tubes of the two winding spindles face each other , that is, the bobbin ends of one winding spindle and the bobbin ends of the other winding spindle face each other. Designed as such. This provides a mirror-symmetric arrangement of the plurality of bobbins on the two spindle supports, so that a common supply surface for the plurality of threads is formed at the center of the bobbin.

  In this case, the abutment surface at the bearing end of the winding spindle can be formed in an advantageous manner by two stopper means, which are configured differently in the two winding spindles, or It is fixed. The stopper means may be a separate ring element or an integrally formed spindle flange.

  According to a particularly advantageous embodiment of the invention, the stop surface is formed directly by the bearing end of the take-up spindle, in which case the spindle supports are held on the machine frame by being offset from one another by the distance of the stop surface. Has been. This makes it possible to use a winding spindle and a spindle support that are identically constructed. The relative position of the winding tube with respect to the yarn supply unit is defined by the displacement of the spindle support in the machine frame.

  In order to be able to wind up a plurality of yarns as continuously as possible, the spindle support is formed by two bobbin revolvers that are rotatably supported, each of which has two windings. Supports the spindle. The winding spindle arranged corresponding to one of the two bobbin revolvers has a contact surface on one of the one stopper surfaces.

  In the winding device according to the invention, the spindle driving device is formed by a friction roller arranged corresponding to the spindle support or formed by a directly driven winding spindle arranged correspondingly with the electric motor. Yes.

  In a directly driven take-up spindle, the yarns are arranged in an advantageous manner by means of a pressure roller that abuts the outer peripheral surface of the bobbin. Such a type of pressure roller is used to adjust the spindle drive at the same time, in which case the two pressure rollers are connected to each other by means of transmission so that they rotate in the opposite direction at a constant rotational speed. According to an advantageous embodiment of the winding device of the invention, an adjustment is possible in which only the rotational speed of one of the two pressure rollers is sensed.

  In order to adjust the yarn tension when winding a plurality of yarns around the bobbin, the pressure roller is advantageously driven by an external drive device.

  In order to carry out a displacement movement during the bobbin increase when winding a plurality of yarns, the pressure roller is advantageously connected to the holder in an advantageous manner, the holder being movable by a carriage and a carriage guide. The pressure roller is displaced in the radial direction relative to the take-up spindle by the holder. This type of displacement movement can also be carried out advantageously in a friction-driven winding spindle. In this case, a friction roller is arranged in the holder instead of the pressure roller.

  A traversing member can be used by a yarn guide formed between two winding spindles. By this traverse member, the supplied yarn is reciprocated before being wound around the bobbin. Accordingly, a plurality of yarns can be traversed in the winding portions facing each other with only one traverse drive device. However, it is also possible to provide two separate traversing members that are driven by two separate drive devices.

  The winding device according to the present invention will be described in detail with reference to several embodiments shown in the drawings.

Has been. In this case, the winding portions 29.1 and 29.2 are arranged in a mirror-like manner with respect to the central left-right symmetric 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 has a first take-up spindle 7.1 and a second take-up spindle 11.1 which is arranged 180 ° offset from it, protruding from the spindle support. Is retained. In the illustrated embodiment, the first winding spindle 7.1 is in a working position for winding a plurality of yarns. The second winding spindle 11.1 is in an exchange position for exchanging the full bobbin with an empty winding tube.

  A second spindle support 10.2 arranged in the same plane is held in the machine frame 12 in the second winding 29.2, mirror-symmetrically with respect to the spindle support 10.1. Yes. The spindle support 10.2 has winding spindles 7.2 and 11.2 protruding from the spindle support 10.2. In the working state shown, the winding spindle 7.2 is in the working position and the winding spindle 11.2 is in the exchange position.

  The spindle supports 10.2 and 10.2 are configured as bobbin revolvers (rotating turrets for bobbins) in this embodiment. The bobbin revolver is rotatably supported and held in the machine frame 12. The two bobbin revolvers 10.1, 10.2 can be driven in opposite rotational directions. The rotary drive device 30 is connected to the central control device 21. Each spindle spindle 7.1, 7.2, 11.1, 11.2 held on the bobbin supports 10.1 and 10.2 has a corresponding spindle drive. FIG. 2 shows the spindle drives 23.2 and 31.2 of the winding spindles 7.2, 11.2 of the winding part 29.2. The spindle driving devices 23.1, 23.2, 31.1 and 31.2 of the winding spindles of the two winding sections 29.1, 29.2 are connected to the central control device 21 (FIG. 3). ).

  In front of the spindle supports 10.1, 10.2, one pressure roller 6.1, 6.2 is provided in the yarn path. In this case, in the winding portion 29.1, the pressure roller 6.1 cooperates with the winding spindle 7.1 so that the plurality of yarns 1.1 are wound around one bobbin 9, respectively. Yes. During winding of the yarn 1.1, the pressure roller 6.1 comes into contact with the outer peripheral surface of the bobbin 9 to be wound.

  Correspondingly, in the winding part 29.2, the pressure roller 6.2 cooperates with the winding spindle present in the working position (in this case 7.2), so that the second thread group is thread 1.2. Is wound on a bobbin. Also in this case, the pressure roller 6.2 comes into contact with the outer peripheral surface of the bobbin 9 to be wound.

  The pressure rollers 6.1 and 6.2 are rotatably supported by the holder 13 and are firmly connected to each other by the holder 13. The holder 13 supports the traverse member 4 disposed in front of the pressure rollers 6.1 and 6.2. The traversing member 4 is arranged in the center plane of the yarn supply between the winding sections 29.1 and 29.2, and a plurality of traversing thread guides 5. These traverse yarn guides cause the supplied yarns 1.1 and 1.2 to reciprocate within the traverse stroke. The traverse member 4 is formed of, for example, a drum with a reversible groove, and this reversible grooved drum has one or more grooves for guiding the traverse yarn guides 5.1 and 5.2 on the outer peripheral surface. is doing.

  A thread guide support 3 is provided on the upper side of the holder 13, and the thread guide support 3 supports two groups of top thread guides 2.1 and 2.2. The top yarn guides 2.1 and 2.2 form a yarn supply section between the winding spindles 7.1 and 7.2. In this case, a group of yarn guides 2.1 is arranged corresponding to the winding part 29.1, and a group of yarn guides 2.2 is arranged corresponding to the winding part 29.2.

  The holder 13 is held by the machine frame 12 so as 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 force sensor 32, and the crimping rotors 6.1 and 6.2 are respectively in a predetermined contact force and the yarn groups 1.1 and 1 .2 abuts each bobbin 9.1, 9.2 during the winding operation of a plurality of yarns. The force sensor 32 is formed by two load-reducing cylinder units 16.1, 16.2, by means of these load-reducing cylinder units, the two pressure rollers 6.1, 6.2 as well as the total weight of the holder and additional A component attached to the holder 13 such as a traverse member 4 is supported. The load reducing cylinder units 16.1, 16.2 acting on the carriage 15 on both sides of the apparatus are connected to the control device 21, and the control device 21 supports the load reducing cylinder units 16.1, 16.2. Can be controlled. Thereby, during winding of a plurality of yarns, the contact force acting between the pressure rollers 6.1, 6.2 and the bobbin 9 is defined by a part of the total weight. As shown in FIGS. 2 and 3, a contact surface 17 is formed on the bearing end of each of the winding spindles 7.1, 11.1 and 7.2 and 11.2. The winding tube end portion of the winding tube 8 contacts the contact surface 17. A contact surface 17.2 is formed by a spindle flange 33.2 on the winding spindles 7.2 and 11.2 of the winding part 29.1. In this case, the contact surface 17.2 tightens the first stopper surface 34.2. In the second winding part 29.1, contact surfaces 17.1 are formed by spindle flanges 33.1 at the bearing ends of the winding spindles 7.1 and 11.1. Since the spindle flange 33.1 is similarly constructed, the abutment surface 17.1 forms a second stopper surface 34.1. Between the stopper surfaces 34.1 and 34.2, an interval indicated by symbol A in FIG. 3 is formed. As a result, the winding tube 8 is held at different relative positions on the winding spindles 7.1, 11.1 and 7.2, 11.2.

  Also in the winding part 29.1 with the winding spindle 7.1 or 11.1 driven in the clockwise direction, also with the winding spindle 7.2 or 11.2 driven in the counterclockwise direction. Also in the take-up part 29.2, in order to form the bobbin 9 having the same take-up direction, in the take-up spindles 7.1 and 11.1, the take-up tube 8 has a free holding area having one catch slit 35 each. Aligned and tightened to be directed toward the end of the spindle. On the other hand, the winding tube 8 in the winding spindles 7.2 and 11.2 is fitted with the gripping region facing the bearing end.

  In the bobbin 9 taken up by the take-up spindle 11.1, the spare thread 36 installed on the outer peripheral surface of the winding tube 8 at the start of the take-up process is directed to the free spindle end. Located on the side. On the other hand, in the take-up spindle 7.2 in the second take-up part, the spare yarn 36 is wound on the side of the bobbin 9 facing the bearing end. Thereby, in the two winding portions 29.1 and 29.2, bobbins having the same winding direction are formed regardless of the reverse winding directions.

  As shown in FIG. 3, the distance A between the stopper surfaces 34.1 and 34.2 is based on the fact that the bobbin 9 is wound around the winding tube 8 asymmetrically. Designed so that bobbin displacement between 1 and 29.2 is fully compensated. As a result, the bobbins 9 of the two winding portions 29.1 and 29.2 face each other mirror-symmetrically, so that the yarn supply portions of the yarns 1.1 and 1.2 are similarly configured. Therefore, the top yarn guides 2.1 and 2.2 are guided by the traverse member in a mirror symmetry.

  In the embodiment shown in FIGS. 1 to 3, the four yarns of the yarn groups 1.1 and 1.2 are wound around one bobbin 9 at the winding portions 29.1 and 29.2. Basically, the number of yarns wound at the same time is only shown as an example, so that one or more yarns can be wound for each winding part 29.1 and 29.2. In practice, however, this type of winding device is used exclusively for winding a plurality of yarns.

  In order to start the winding process at the winding spindles 7.1 and 7.2, the pressure rollers 6.1 and 6.2 are moved in the lower position by the carriage 15 and the load reducing cylinder units 16.1 and 16.2. Guided. When the yarns 1.1 and 1.2 of the yarn group are caught in the winding tube 8 and the spare yarn 36 is wound, the winding motion is started. During winding of the bobbin 9, the load reducing cylinder units 16.1 and 16.2 are adjusted and controlled so that a predetermined contact force acts on the bobbin 9. This abutment force is kept constant during the winding of the yarn on the winding spindles 7.1 and 7.2 in an advantageous manner. For this purpose, for example, the load reducing pressure in the load reducing cylinder units 16.1 and 16.2 is adjusted to a predetermined value, sensed and controlled via the control device 21. With this type of pressure adjustment, the displacement movement of the carriage 15 is also controlled in an advantageous manner.

  During the winding of a plurality of yarns of the yarn groups 1.1, 1.2, the required displacement movement based on the increase of the bobbins 9.1 and 9.2 is basically kept movable in this embodiment. 15 and also by take-up spindles 7.1 and 7.2 held movably. By the press rollers 6.1 and 6.2 being fixedly arranged on the holder 13, the bobbin 9 is increased synchronously by the movement of the carriage 15.

  The rotary drive 30 of the spindle supports 10.1 and 10.2 is preferably driven stepwise or continuously in order to carry out the displacement movement. In this case, the two spindle supports 10.1 and 10.2 are connected to each other by transmission means.

  In order to explain the driving idea of the embodiment of the winding device according to the invention, two possible examples will be described below with reference to FIGS. For the sake of clarity, only the portions of the windings 29.1 and 29.2 necessary for driving are shown schematically from the rear in FIGS.

  In the driving concept shown in FIG. 4, the winding spindle 7.1 is connected to the spindle drive 23.1 via the spindle end 22.1 in the winding part 29.1. A controller 24.1 is arranged corresponding to the spindle driving device 23.1, and this controller 24.1 is connected to the host control device 21. In this case, the bobbin 9 taken up by the take-up spindle 7.1 is indicated by a broken line. On the outer peripheral surface of the bobbin 9, a pressure roller 6.1 supported so as to be freely rotatable is applied, and this pressure roller 6.1 is similarly indicated by a broken line. The pressure roller 6.1 has a roller end 18.1. A rotation speed sensor 20 is arranged in correspondence with the roller end 18.1, and the rotation speed sensor 20 can detect the rotation speed of the pressure roller 6.1. The rotation speed sensor 20 is connected to the control device 21.

  In the second winding part 29.1, the winding spindle 7.2 is connected to the spindle drive 23.2 by a spindle end 22.2. A controller 24.2 is arranged correspondingly to the spindle drive 23.2, which is likewise connected to the controller 21. A bobbin 9, similarly indicated by a broken line, formed on the outer peripheral surface of the winding spindle 7.2 is in contact with the second pressure roller 6.2. Similarly, the pressure roller 6.2 of the second winding portion 29.2 is rotatably held. In this case, the pressure roller 6.2 is connected to the pressure roller 6.1 of the first winding portion 29.1 via the transmission means 19 at the roller end 18.2. In this embodiment, since the transmission means 19 is mechanically constituted by a belt or a chain, the two pressure rollers 6.1 and 6.2 of the two winding portions rotate at the same rotational speed. In order to wind up the plurality of yarns 1.1 at the winding part 29.1, the winding spindle 7.1 is driven in the clockwise direction by the spindle drive 23.1. The pressure roller 6.1 is in contact with the outer peripheral surface of the bobbin 9 to be wound, and is driven in the reverse rotation direction via friction.

  In order to wind the yarn 1.2 around the bobbin 9, the winding spindle 7.2 is driven in the clockwise direction by the spindle drive 23.2 in the winding part 29.2. In this case, the pressure roller 6.2 rotates on the outer peripheral surface of the bobbin 9 in the clockwise direction at a rotation speed corresponding to the pressure roller 6.1. Transmission of rotational force between the pressure rollers 6.1 and 6.2 is performed by the transmission means 19. Since the two winding parts 29.1 and 29.2 are wound synchronously, the bobbin 9 is similarly configured in each winding bobbin 7.1 and 7.2.

  In order to obtain a constant winding speed of the yarns 1.1 and 1.2, the rotational speed of the pressure roller 6.1 is continuously detected by the rotational speed sensor 20 and sent to the control device 21. The control device 21 stores a target rotational speed of the pressure roller 6.1. If an unacceptable difference is detected between the detected actual rotational speed of the pressure roller 6.1 and the stored target rotational speed of the pressure roller 6.1, a control signal is generated and the controller 24. 1 and 24.2. The controllers 24.1 and 24.2 change the drive speed of the spindle drives 23.1 and 23.2 so that the actual speed changed in the pressure roller 6.1 is obtained in the desired manner. This adjusts the constant peripheral speed of the bobbin 9 during the entire winding operation of the intentions 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.

  The embodiment shown in FIG. 5 is substantially 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 the motors 28.1 and 28.2 and the controller 27 to which it belongs. As a result, the electrical connecting portions of the pressure rollers 6.1 and 6.2 are combined with the external driving device 25.

  However, it is also possible to couple the pressure rollers 6.1 and 6.2 to the transmission means and drive them with only one electric motor.

  For the embodiment shown in FIG. 4, the take-up spindles 7.1 and 7.2 are driven by spindle drives 23.1 and 23.2, respectively. In this case, the spindle driving devices 23.1 and 23.2 may be configured as asynchronous motors or synchronous motors. A controller 24 is arranged corresponding to each of the spindle driving devices 23.1 and 23.2. The controller 24 is connected to the control device 21 and forms an adjustment circuit together with the rotational speed sensor 20 to keep the peripheral speed of the bobbin 9 constant.

  6 and 7 show schematic views of another embodiment of the winding device according to the invention as seen from different directions. 6 is a front view, and FIG. 7 is a schematic plan view of winding spindles arranged side by side of the winding apparatus. The following description applies to both drawings, unless otherwise noted.

The embodiment shown in FIGS. 6 and 7 has two windings 29.1 and 29.2, which are arranged side by side in the machine frame 12. FIG. In this case, the winding portions 29.1 and 29.2 are arranged side by side mirror-symmetrically. In the winding part 29.1, a first winding spindle 7.1 projects in a cantilevered manner and is rotatably held by a stationary spindle support 10.1. The spindle support 10.1 is fixed to the machine frame 12. In the second winding section within 29.2 adjacent in the horizontal direction, that the second spindle support 10.2 is fixed similarly to the machine frame 12. A second take-up spindle 7.2 is cantilevered and supported rotatably on the spindle support 10.2. Each winding spindle 7.1 and 7.2 has a winding tube 8 for receiving a bobbin 9.

As shown in FIG. 7, a contact surface 17.1 is formed on the bearing end of the winding spindle 7.1, and a contact surface 17.2 is formed on the winding spindle 7.2. Yes. These contact surfaces 17. 1 and 17.2 are located on two adjacent stopper faces 34.1, 34.2 which are spaced from one another. The abutment surfaces 17.1 and 17.2 are formed directly by the bearing ends of the take-up spindles 7.1 and 7.2. For this purpose, the spindle support 10.1 protrudes from the machine frame 12 slightly larger than the spindle support 10.2. Thereby, the difference in length protruding from the machine frame 12 between the spindle support 10.1 and the spindle support 10.2 defines the distance A between the stopper surface 34.1 and the stopper surface 34.2. . The distance A between the stopper surfaces 34.1 and 34.2 is designed so that the bobbin ends of the two bobbins 9 formed on the two wound tubes 8 are in positions facing each other. In this case, the spare yarn 36 in the winding tube 8 is wound around the free end of the winding spindle 7.1 and wound around the bearing end of the winding spindle 7.2.

  As shown in FIG. 6, one friction roller 37.1 and 37.2 is assigned (corresponding arrangement) to the winding spindles 7.1 and 7.2, respectively. Since these friction rollers 37.1, 37.2 are driven, the winding spindles 7.1 and 7.2 or the bobbin 9 are driven by friction to wind the yarns 1.1 and 1.2. The Friction rollers 37.1 and 37.2 are attached to holder 13. The holder 13 is guided by the machine frame 12 through the carriage 15 and carriage guides 14.1 and 14.2 so that the height can be adjusted. Load reducing cylinder units 16.1 and 16.2 act on the carriage 15. On the one hand, the necessary contact force between the friction rollers 37.1 and 37.3 and the bobbin 9 is provided. On the other hand, the displacement movement of the friction rollers 37.1 and 37.2 relative to the take-up spindles 7.1 and 7.2 necessary during the increase of the bobbin 9 is carried out. In this case, the friction for adjusting the carriage 15 is substantially the same as that of the embodiment shown in FIGS.

  Top thread guides 2.1 and 2.2 are arranged on the upper side of the holder 13 in order to be able to feed the thread between the bobbin spindles 7.1 and 7.2. A traverse member 4 is arranged between the top yarn guides 2.1 and 2.2 and the friction rollers 37.1 and 37.2. The traverse yarn guides 5.1 and 5.2 enter the yarn path, and the traverse yarn guides 5.1 and 5.2 allow the yarns 1.1 and 1.2 to move within the traverse stroke. It can be reciprocated.

  In the embodiment of the winding device according to the invention shown in FIGS. 6 and 7, one thread is wound on one bobbin in each winding spindle 7.1 and 7.2. However, this type of winding device can also be configured to wind a plurality of yarns on one winding spindle. In contrast to the embodiment shown in FIGS. 1 to 3, the embodiment shown in FIGS. 6 and 7 relates to a partially automatic winding device. In this case, after the fully wound bobbin is obtained, the winding process is interrupted for bobbin replacement. Only after the completed bobbin is replaced with an empty winding tube will a new winding process begin. Also in this case, bobbins having the same winding direction are formed in the two winding portions.

  The winding device according to the invention is particularly suitable for winding freshly spun yarn. In this case, the yarn is drawn from the spinning device or the processing device. By shifting and tightening the winding tube, it is possible to supply a plurality of yarns to the two winding portions in a common yarn path plane, so that there is an advantage that no additional displacement movement is necessary. Yes. Further, the yarn guide means in the winding device, for example, the top yarn guide and the traverse member, can be configured identically in the two winding portions.

  The winding device according to the present invention is not limited to the arrangement of the individual devices shown in FIGS. Basically, the pressure roller can be held movably in the radial direction with respect to the winding spindle by vibrations, especially in the winding section. The holding of the winding spindle and the pressure roller is mainly necessary only for carrying out the displacement movement. Similarly, in order to traverse a plurality of yarns before winding them around a bobbin, a separate traverse member may be provided at each winding portion.
