Description

  The present invention relates to a winder that winds a plurality of yarns around a package in parallel, according to the upper conceptual part of claim 1.

  A winder of this type is known from WO 2006/092237 (WO 2006/092237 A1).

  This known winder is used for winding yarns produced in a melt spinning process. The yarns of the yarn group are wound around the package in parallel with each other. For this purpose, the winder has a plurality of winding points formed in the machine frame along a winding spindle that is cantilevered and held. The take-up spindle is used to receive the package for simultaneous take-up on the package. Since the winding of the yarn is performed by so-called traverse winding, each yarn is individually reciprocally guided by the traverse unit before being wound up on the package surface within the winding position. The supply and separation of the yarn group at the winding position is performed via a plurality of turning rollers rotatably supported, and these turning rollers are supported by a movable support. At this time, each turning roller forms one traverse plane together with the corresponding traversing unit, and the yarn is guided back and forth within the traverse plane. In such a state, the support is fixed to the machine frame of the winder in the operating position.

  In order to allow the yarn of the yarn group to pass through the winding position of the winder at the start of the process, the support having the turning roller is pulled out of the machine frame so that the turning roller can be threaded from the operating side. It is. At this time, the support is manually moved by the operator.

  However, during the production of synthetic yarns, it is desirable to wind up as many yarns as possible in a winder. It therefore requires a very long support which must be guided to the working path with a corresponding extrusion length. This makes the setting process difficult for an operator who, on the one hand, has to guide the support and on the other hand to thread the turning roller.

  Further, it is known that when the yarn is wound, strong and small vibrations are generated in the machine frame depending on the spindle rotational speed at each time. Therefore, the yarn is wound around the package at a constant winding speed and thus at a constant peripheral speed. In order to keep the peripheral speed of the package constant, the rotation speed of the winding spindle is adjusted according to the diameter of the package. These vibrations generated in the machine frame are generated particularly at a winding position corresponding to the protruding free end of the winding spindle. At this time, it has been found that such vibration also affects the support body of the turning roller and acts on all the support portions of the turning roller.

  The object of the present invention is therefore to improve a winder of this type and to hold the turning roller in the machine frame with as little vibration as possible.

  A further object of the invention is to improve such a winder in threading operability at the start of the process.

  Such a problem is solved according to the invention by a winder having the features of claim 1.

  Advantageous refinements of the invention are defined by the features and combinations of features of the dependent claims.

  The invention has the special advantage that the deflection rollers are supported on the machine frame independently of each other. For this purpose, a roller holder is arranged in correspondence with each of the diverting rollers, and the diverting rollers are supported on the roller holders. In the roller holder, adjacent turning rollers are held at a winding interval at an operating position and held at a threading interval at a threading position. At this time, the winding interval is larger than the threading interval. In this way, the roller support is guided so as to be movable independently of each other. At the same time, operability at the projecting end of the take-up spindle by the operator can be realized. Thus, all roller holders with turning rollers can be guided towards the projecting end of the take-up spindle in order to facilitate threading at the start of the process. Subsequently, the roller holder with the turning roller can be guided in the winding position in the operating position. The mutual influence of the deflecting rollers is minimized by the separately provided supports in the roller holder.

  In order to automate the yarn setting process at the winding site, the improvement of the invention is particularly preferred, in which at least one of the roller holders is associated with a linear drive, Sometimes adjacent roller holders are connected to each other by variable length coupling means. Accordingly, the roller holder has individual movability, but can be guided between the operating position and the threading position by the linear drive device.

  The linear drive is preferably connected to the winding control unit and is operable via a control panel. Thus, the setting process in the winder can be executed while being adjusted.

  In particular, the improvement of the invention is particularly advantageous in order to enable the setting and winding of thin threads at all winding points of the winder, in which the turning roller is at the winding point. And it is connected with the drive device so that it can be driven outside the winding point. By doing so, the turning roller can be driven at a predetermined peripheral speed already in the threading position. Thereby, particularly unacceptable fluctuations in the thread tension during threading can be avoided.

  In order to guarantee the driving of the deflecting roller at the winding position, the drive device can be configured in a wide variety of structures. According to one particularly advantageous alternative embodiment, the drive device comprises a belt drive device, which is connected to the turning roller by a shape connection or a friction connection and is separate. The drive device support is mounted on the machine frame in a stationary or movable manner.

  At this time, the belt driving device may have a driven toothed belt, and the driven toothed belt cooperates with each one of the plurality of toothed pulleys. Is connected to the turning roller in a non-rotatable manner.

  Another particularly advantageous variant of the belt drive comprises a driven magnet belt, which is not contacted with a plurality of magnet disks which are non-rotatably connected to the turning roller. Work together. At this time, the magnet belt advantageously extends over the entire length of the machine frame, so that continuous driving of the turning roller is ensured even during relative movement between the magnet disk and the magnet belt.

  If the drive support of the belt drive is held movably on the machine frame, the improvement of the present invention is preferably implemented, in which the winding control unit has a feed acting on the drive support. Coupled to the drive unit, the linear drive unit and the feed drive unit of the roller holder can be controlled synchronously. Thus, for example, the connection by means of a shape connection between the toothed disk and the toothed belt continues during the movement of the roller holder.

  However, basically, the driving device may be constituted by a plurality of electric motors respectively held by a roller holder and connected to a turning roller. At this time, it is possible to supply power to these electric motors via one energy chain.

  Alternatively, however, the electric motor may be connected to a plurality of filling stations at the working position of the turning roller and the threading position of the turning roller. At this time, the motor receives the necessary supply energy and control signal transmitted only in the operating position and the threading position.

  At this time, the transmission of the supply energy and the control signal is preferably performed in a non-contact manner. For this purpose, a variant of the invention is provided in which a plurality of transmission means for wireless energy transmission are provided between the motor and the filling station.

  In order to be able to generate as much torque as possible on the deflecting roller as much as possible during all stages of threading and operation, the improvement of the present invention is particularly advantageous, in which the motor includes Corresponding capacitors are arranged for energy storage. At this time, the capacitor functions as an energy storage device that guarantees energy supply to the motor outside the filling station.

  For further explanation of the invention, several embodiments of a winder according to the invention will be described in detail below with reference to the accompanying drawings.

It is a figure which shows schematically a part of front view of another embodiment of the winding machine by this invention. It is a figure which shows roughly a part of rear view of embodiment of FIG. FIG. 6 schematically shows part of a rear view of another embodiment of a winder according to the invention. FIG. 6 schematically shows part of a rear view of another embodiment of a winder according to the invention. It is a figure which shows schematically a part of front view of another embodiment of the winding machine by this invention. It is a figure which shows roughly a part of rear view of embodiment of FIG.

  1 and 2, a first embodiment of a winder according to the invention is shown in several directions. FIG. 1 shows a side view of the present embodiment, and FIG. 2 shows a front view. Embodiments of the winder according to the invention are shown in an activated state in FIGS. 1 and 2, respectively, in which a group of yarns of a plurality of yarns are simultaneously wound onto a package. In this respect, at the same time, the function of the winder can be clearly indicated by the running of the yarn.

  The following description of the present embodiment of FIGS. 1 and 2 applies to both drawings unless explicitly stated in one of these drawings.

  In this embodiment, the winder has a total of five winding points 1.1 to 1.5 formed along a winding spindle 10.1 protruding in a cantilever manner. This number of winding locations is an example. Thus, it has been customary to wind ten, twelve or more yarns side by side in parallel to one another on a package on a driven winding spindle.

  In the present embodiment, the take-up spindle 10.1 is held by a take-up revolver 11 that is rotatably supported, and the take-up revolver 11 is shifted to the second take-up spindle 10. 2 is supported. Two spindle driving devices 20.1, 20.2 are respectively arranged corresponding to the winding spindles 10.1, 10.2. The revolving movement of the winding revolver 11 that is rotatably supported in the machine frame 14 is performed by a revolver driving device 22. By means of the revolver drive device 22, the take-up revolver 11 can move with the take-up spindles 10.1, 10.2. Therefore, the winding spindles 10.1, 10.2 can be rotated alternately to the exchange area and the working area. Since a plurality of winding tubes 13 are arranged around the winding spindles 10.1 and 10.2, one package 12 is wound on the winding tube 13 at each winding location 1.1 to 1.5. It is possible to take.

  In the operating state shown in FIGS. 1 and 2, a total of five yarns 2 are simultaneously wound on five packages 12 on the winding spindle 10.1.

  The winding points 1.1 to 1.5 formed in the winding machine have turning rollers 3.1 to 3.5 in the run-in area, respectively, for separating and guiding yarns. The diverting rollers 3.1 to 3.5 cooperate with the traverse unit 4 in the respective winding points 1.1 to 1.5. The turning rollers 3.1 to 3.5 and the correspondingly arranged traverse unit 4 form a so-called traverse plane, and the yarn 2 is guided in a reciprocating manner within this plane, so that traversing occurs around the package. . For this purpose, the traverse unit 4 formed at the winding points 1.1 to 1.5 has traverse means, and the traverse means guides the yarn during the traverse stroke. At this time, as a traversing means, a yarn guide that reciprocates or a plurality of yarn guides that perform a translational movement may be used.

  The winding of the yarn around the package 12 is supported by a rotatable pressing roller 9, which extends over all winding points 1.1 to 1.5, 12 is in contact with the surroundings.

  In the upper region of the machine frame 14, turning rollers 3.1 to 3.5 are rotatably supported by a plurality of roller holders 5.1 to 5.5. The roller holders 5.1 to 5.5 include bearings 17 for the deflection rollers 3.1 to 3.5, which are not shown in detail here. Each roller holder 5.1 to 5.5 is configured to be movable, and is disposed on the roller support 6. The roller support 6 is in this case formed by a guide rod, which extends above the winding location to the machine frame 14 and parallel to the winding spindle 10.1.

  A roller holder 5.1 arranged corresponding to the bearing end of the winding spindle 10.1 is connected to the linear drive device 15.

  Between adjacent roller holders 5.1 and 5.2, between 5.2 and 5.3, between 5.3 and 5.4, and between 5.4 and 5.5, Each coupling means in the form of a telescopic rod 7 is arranged. The telescopic rod 7 couples the roller holders 5.1 to 5.5 to each other. At this time, the telescopic rod 7 is configured to have a variable length. With such a configuration, the roller holders 5.1 to 5.5 can be moved on the roller support 6 in the axial direction by the linear drive device 15. In the state shown in FIGS. 1 and 2, the roller holders 5.1 to 5.5 are respectively held at operating positions where the yarn 2 is wound around the package 12. At this time, the yarn 2 is guided in a state of being partially wound around the turning rollers 3.1 to 3.5.

  The linear drive device 15 is connected to the winding control unit 8 via a control line. The winding control unit 8 is connected in parallel to a control panel 18 on the front operation side of the winder and a drive electronic device 19. The drive electronic device 19 is connected to the spindle drive devices 20. 1, 20.2, the traverse drive device 21 of the traverse unit 4, and the revolver drive device 22. The operation and drive control of the drive devices 20.1, 20.2, 21 and 22 are performed via the winding control unit 8 schematically shown and the control panel 18 arranged correspondingly.

  In this embodiment shown in FIG. 1 and FIG. 2, a driven godet 23 is arranged corresponding to the winding points 1.1 to 1.5, and this godet 23 is located on the side of the winder. Since the yarn 2 is held, the yarn 2 is supplied to the turning rollers 3.1 to 3.5 at the winding points 1.1 to 1.5 without further widening by the substantially horizontally oriented yarn guide. Can do. The godet 23 is driven via a godet driving device 24 controlled by a godet control device 25.

  In the operating state of the winder shown in FIGS. 1 and 2, the yarn 2 is supplied as a single yarn group to the winding locations 1.1 to 1.5 via the godet 23, and the turning roller 3.1. Separated through ~ 3.5. Subsequently, each yarn 2 is separately wound into one of a plurality of packages 12 provided around the winding spindle 10.1 in the winding points 1.1 to 1.5.

  When the package reaches a predetermined final diameter, the spindle is replaced. At this time, the take-up spindle 10.1 is rotated to the replacement area, and the take-up spindle 10.2 is rotated to the operating area. At this time, since the yarn is automatically captured and taken up by the winding tube 13 existing around the winding spindle 10.2, the yarn is wound around the winding spindle 10.2 to form a new package.

  The winder shown in FIGS. 1 and 2 is particularly suitable for holding a number of winding points side by side. By separately supporting the deflection rollers 3.1 to 3.5 in the roller holders 5.1 to 5.5, the bearing portions of the deflection rollers 3.1 to 3.5 are provided separately. , Mutual vibrations do not affect each other. Furthermore, the roller holders 5.1 to 5.5 can be transferred to one threading position between the illustrated operating positions inside the machine frame 14. The threading positions of the roller holders 5.1 to 5.5 are indicated by broken lines in FIG.

  As is apparent from FIG. 1, first, the roller holder 5.1 arranged on the roller support 6 is moved to the protruding spindle free end of the take-up spindle 10.1 via the linear drive unit 15. . At this time, the telescopic rod 7 disposed between the roller holders 5.1 and 5.2 is also pressed together, so that the next roller holder 5.2 is entrained as this pressing motion proceeds. Therefore, as the pressing movement of the linear drive device 15 proceeds, all the roller holders 5.1 to 5.5 arranged on the roller support 6 are moved to the end stopper 16 at the free end of the take-up spindle 10.1. I can guide you. At the threading positions indicated by the broken lines of the roller holders 5.1 to 5.5, the turning rollers 3.1 to 3.5 have a threading interval between them, respectively. At this time, the threading interval is much smaller than the winding interval that occurs at the operating position of the roller holders 5.1 to 5.5 between the adjacent deflecting rollers 3.1 to 3.5. In this case, the winding interval is a pitch of the winding points 1.1 to 1.5. The threading interval of the deflecting rollers 3.1 to 3.5 at the threading position depends on the coupling means 7. Basically, other coupling means that can considerably reduce the distance between the deflection rollers 3.1 to 3.5 may be used.

  At the threading position indicated by the broken line in FIG. 1, the operator can easily hang the thread 2 on the turning rollers 3.1 to 3.5 at the start of the process. At this time, the linear drive device 15 can be operated by a simple key input on the control panel 18. Therefore, even if there are many winding parts, the operator can perform all the work processes quickly and easily.

  In the embodiment shown in FIGS. 1 and 2 of the winder according to the invention, a drive device is arranged correspondingly to the diverting rollers 3.1 to 3.5, and the diverting roller is activated by this driving device. Can also be driven. For this purpose, in FIG. 2, as an example of a plurality of electric motors 26, how this is arranged on the back surface of the roller holders 5.1 to 5.5 is indicated by broken lines. Drive control of these electric motors and energy supply to these electric motors can be performed via a flexible energy chain (energy supply line). Therefore, the deflection rollers 3.1 to 3.5 can be continuously driven both in the operating position and in the threading position. This is particularly advantageous when setting a small count yarn and winding it.

  Moreover, the driving device 27 shown in FIG. 2 may be implemented by other driving means. Thus, for example, FIGS. 3 and 4 show another embodiment of a winder according to the invention, which is configured differently from the embodiment of FIGS. 1 and 2 in FIGS. Only the device part is shown. For example, FIG. 3 shows a portion of the front view of the winder embodiment, and FIG. 4 schematically shows a portion of the rear view of the winder embodiment. Unless stated explicitly with respect to one of these drawings, the following description applies to both drawings.

  In the embodiment shown in FIG. 3 and FIG. 4, the deflecting rollers 3.1 to 3.5 and the roller holders 5.1 to 5.5 are configured in the same way as in the above embodiment, and the roller support 6 is movable in the axial direction by the linear drive device 15. A driving device 27 having a belt driving device 28 is formed on the back surface of the roller holders 5.1 to 5.5. In this embodiment, the belt driving device 28 is formed by one toothed belt 29 and two belt pulleys 30.1 and 30.2 that are spaced apart from each other. The belt pulley 30.2 is coupled to the motor 34 via the motor shaft 35. The belt pulleys 30.1 and 30.2 are rotatably supported on the driving device support 31. The driving device support 31 is held by the machine frame 14 on the guide rail 36 so as to be movable in the axial direction. On one side of the drive device support 31, a feed drive device 32 that can reciprocate the drive device support 31 between the operating position and the threading position in the machine frame 14 is provided.

  As is clear from FIG. 3 in particular, one toothed pulley 33 is rotatably held on the back of the roller holders 5.1 to 5.5, and each toothed pulley 33 is connected to each direction roller. It is relatively non-rotatably coupled to 3.1 to 3.5. Since the toothed pulley 33 is engaged with the toothed belt 29, transmission by shape connection is possible between the toothed belt 29 and the toothed pulley 33. Therefore, all the diverting rollers 3.1 to 3.5 can be uniformly driven via the belt driving device 28.

  At the start of the process, the turning rollers 3.1 to 3.5 and the drive device 27 are guided together to the threading position at the free end of the winding spindle. By doing so, the deflection rollers 3.1 to 3.5 can be continuously driven at the threading position. When the threading is finished, the linear drive device 15 and the feed drive device 32 are synchronously controlled, so that the roller holders 5.1 to 5.5 and the belt drive device 28 are guided to the operating position. By doing so, the continuous drive of the diverting roller continues to be maintained in all operating states of the winder.

  The driving device 27 for driving the deflecting rollers 3.1 to 3.5 shown in FIGS. 3 and 4 may be changed to transmit the rotational motion by the frictional connection instead of the transmission by the shape connection. Is possible. In this regard, FIG. 5 shows a part of a rear view of another embodiment of a winder according to the invention. Since the embodiment of FIG. 5 is substantially the same as the embodiment of FIGS. 3 and 4, only the differences will be described here.

  In the driving device 27 shown in FIG. 5, the belt driving device 28 is formed by a magnet belt 34. The magnet belt 34 includes a number of magnets having alternating polarities. The magnet belt 34 is guided by a belt pulley 30.1 and a belt pulley 30.2 (not shown here). A plurality of magnet disks 35 are arranged corresponding to the magnet belt 34 at short intervals, and these magnet disks 35 are rotatably held on the back surfaces of the roller holders 5.1 to 5.5. And coupled to the deflection rollers 3.1 to 3.5. Only the magnet disk 35 of the roller holder 5.5 is shown in FIG. In such a case, torque transmission is performed by a magnetic force formed between the magnet disk 35 and the magnet belt 34.

  In the embodiment shown in FIG. 5, the belt driving device 28 is held by a driving device support 31. Moreover, at this time, the driving device support 31 may be formed in a stationary manner in the machine frame and may extend over the entire length of the winding spindle. The non-contact coupling between the magnet disk 35 and the magnet belt 34 allows the relative movement of the roller holders 5.1 to 5.5 without interruption of the drive. The magnet belt therefore preferably extends over the area of the threading position and the operating position of the deflection rollers 3.1 to 3.5.

  In order to be able to generate as high a torque as possible in the diverting rollers 3.1 to 3.5, another embodiment of the drive device 27 is shown in FIG. The embodiment of FIG. 6 is substantially the same as the embodiment of FIG. 5, so reference is made to the above description, but for other points only the differences will be described here.

  In the embodiment shown in FIG. 6 of the drive device 27 of the deflection rollers 3.1 to 3.5, the magnet belt 34 acts on both sides in the diametrical direction of the magnet disk 35, and thus the generated torque increases. Thus, the magnet disk 35 is disposed between the belt pulleys 30.1 and 30.2.

  In the modification shown in FIGS. 1 and 2 of the winder according to the present invention, a selective driving device having a plurality of electric motors is provided. In the case of such a drive device, basically, the electric motor that drives the deflecting rollers 3.1 to 3.5 can also operate without an energy chain (energy supply line). In this regard, FIGS. 7 and 8 show how one possible embodiment of the drive device 27 can be used, for example in the winder shown in FIGS. 1 and 2. It is shown. A plurality of filling stations 37 disposed on the back surface of the roller holders 5.1 to 5.5 are disposed in correspondence with the electric motors 26 disposed on the roller holders 5.1 to 5.5. Each electric motor 26 is provided with a separate filling station 37 corresponding to each of the operating positions of the deflection rollers 3.1 to 3.5. These filling stations 37 are identically configured and have a transmitter 38 for transmitting supply energy and control signals to the motor 26. In this case, energy transfer can be performed by inductive coupling using an induction coil or optical coupling. And alternatively, the transmitter 38 may have an automatic connector that forms a connection between the filling station 37 and the motor 26 in the operating position.

  As is apparent from FIG. 8, a filling station group 40 is provided outside the winding portion of the protruding end of the machine frame 14, and the filling station group 40 changes the energy supply to the electric motor 26. Guaranteed at the threading positions of the direction rollers 3.1 to 3.5. By doing so, the diverting rollers 3.1 to 3.5 can be continuously driven by the correspondingly arranged electric motors 26 in the operating position and the threading position.

  In the embodiment shown in FIG. 7, the electric motor 26 is correspondingly arranged with a capacitor 39 that is directly connected to the electric motor 26 and forms an energy buffer. Thereby, even if there is no effect | action of the filling station 37, the energy supply to the electric motor 26 can be maintained for a short time. Accordingly, such energy supply enables continuous driving of the diverting rollers 3.1 to 3.5 during the transition from the threading position to the operating position. In such a state, one yarn is guided around each of the turning rollers 3.1 to 3.5.

  The winder according to the present invention is suitable for winding a large number of yarns at a large number of winding points with or without a driven turning roller. Furthermore, simple operability at the start of the process can be realized by the individual movability of the deflection roller.
