At least one of the pivoting arms is held, in a removal position, in alignment with the winding spindle of the winding machine for the removal of the bobbin. The pivoting shaft is oriented horizontally, and the pivoting arms are guidable in a vertically oriented guidance plane.

Description

  The present invention relates to an apparatus for removing a bobbin in a winder described as a superordinate concept of claim 1.

  In the production of synthetic yarns, the yarns are usually melt-spun and then wound on individual bobbins by a winder. In order to achieve a continuous material flow, it is advantageous to have two take-up spindles arranged in a movable holding body and held in a cantilevered manner alternately in the take-up area and the exchange area A winder is used. The yarn melted by this winder is continuously wound on the bobbin without interruption of the process. For further automation, it is known to arrange correspondingly on the winder a device for receiving the bobbin from the winder after production and for example removing the bobbin supplied to the bobbin transport device. Such a device is known from DE 4421916 A1.

  In this known device, a plurality of swivel arms spaced from each other are held on a swivel shaft. In this case, a first swivel arm for receiving the bobbin and a second swivel arm for supplying the winding tube are preferably used. The swivel arm is held in a horizontal plane and is moved from the removal position to the delivery position by a vertically oriented swivel axis. The swivel arm is in this case arranged in the form of a rotating cross on the swivel axis.

  In the case of the known device, the swivel arm protrudes significantly beyond the side area of the winder during rotation in relation to the number of bobbins and thus in relation to the overhang length of the swivel arm. However, when producing melt-spun yarns, it is common to produce a large number of yarns by arranging a large number of winders in a row. Therefore, the known apparatus requires a larger space between the adjacent winders, and the required space of the entire equipment increases.

  The object of the invention is therefore to improve a bobbin removal device of the type mentioned at the outset so that the bobbin removal takes place approximately in the machine width region of the winder.

  Another object of the present invention is to provide an apparatus for removing a bobbin of the type described at the outset, which can be highly automated when the bobbin is taken out and the winding tube is supplied.

  The object of the present invention has been solved according to the invention by a device having the features of claim 1.

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

  An advantage of the present invention is that the bobbin produced on the winder can be removed and carried out at any time and at any time interval. The advantage of the device used for placement is thus maintained for bobbin removal. More particularly, the space obtained above is utilized to remove and transport a plurality of bobbins from the winder in the narrowest space. For this purpose, the swivel arm is guided by a horizontally oriented swivel axis in a vertically oriented guide plane. Therefore, the swivel arm requires only a required space that does not greatly exceed the width of the bobbin. The device is therefore particularly suitable for unloading bobbins on a number of winders forming the machine longitudinal side. The spacing between adjacent winders is determined solely by the machine width of the winder.

  After receiving the wound bobbin from the winder, the released winding spindle is usually equipped with a winding tube for a new start of the winding process, which is a particularly advantageous configuration according to the invention. Accordingly, the swivel arms are offset from each other in one guide plane and held on the swivel shaft, and the swivel arms can be alternately brought to the removal position. This achieves a short interruption time. This is because the removal of the bobbin is performed on one side of the swivel arm, and the supply of a new winding tube is performed on the second swivel arm. In this case, the angle between the swivel arms is set so that there is no problem in removing the bobbin from one swivel arm, carrying out the bobbin, and installing the winding tube for the second swivel arm.

  An angle between swivel arms having a size in the region of 90 ° has proven to be advantageous in that the bobbin removal and the winding tube supply can be carried out with minimal space.

  High flexibility between the removal of the bobbin and the supply of the winding tube is possible in the device according to the invention if the swivel arm is configured to be pivotable clockwise and / or counterclockwise on the pivot axis. In particular, it is advantageous if the reciprocating movement of the swivel arm is used so that the energy supply of the auxiliary device arranged corresponding to the swivel arm can be carried out in a simple manner with a cable guide.

  For this purpose, the swivel shaft is preferably rotatably supported on a stationary holding body and connected to a rotary drive. Since the holding end of the swivel arm is fixedly coupled to the swivel shaft, the swivel arm can be swung directly via the rotary drive device.

  In order to ensure that the bobbin removed from the winder is quickly and reliably unloaded, a bobbin transport device is provided, and the bobbin transport device has at least one bobbin receiving station per winder. ing. Accordingly, at least one of the swivel arms can be guided from the removal position to the delivery position of the bobbin receiving station.

  When using a transportable transport device, it is advantageous if a further configuration of the invention is used. In this configuration, the bobbin receiving station is arranged facing the winder, and the swivel arm can swivel between the removal position and the delivery position at a swivel angle in the region of 180 °. In this case, in order to convey the bobbin, a conveyance path oriented parallel to one side in the machine longitudinal direction can be used.

  However, the bobbin receiving station can also be configured on the floor in front of the winding machine. The swivel arm held so as to be pivotable between the removal position and the delivery position has a clamp mechanism for fixing the bobbin. Thereby, the bobbin can be guided from the removal position to the delivery position by a simple turning of 90 °.

  When manufacturing synthetic yarn, the bobbin may have insufficient size due to yarn breakage during winding or may have insufficient yarn quality due to process guidance defects . In these cases, it is advantageous for the bobbin conveying device to have a plurality of bobbin receiving stations per winder, and that the bobbin receiving station forms a plurality of delivery positions in the swivel area of the swivel arm. As a result, classification can be performed when the bobbin is already removed. Thus, the defective bobbin can be separately removed and transported to one of the delivery positions.

  For receiving the bobbin guided by the swivel arm, the bobbin receiving station is composed of a movably guided bobbin mandrel which is aligned and held with respect to the swivel arm at the delivery position, or a bobbin chute or a transport belt which travels and moves Can be configured.

  For complete automation, the swivel arm is associated with a tube delivery station for the tube supply device. The winding tube delivery station preferably has one guide tube, which is held in axial alignment with at least one pivot arm at the filling position.

  For feeding the winding tube to the swivel arm waiting in the filling position, it is advantageous, according to another configuration of the invention, that the winding tube supply device is configured above the winding spindle and before the winder. . As a result, the winding tube is transferred from the guide tube to the swivel arm only by gravity. Additional guiding means are not necessary.

  However, it is also possible for the winding tube delivery station to be configured on the floor and in front of the winder. In this case, the swivel arm held in the filling position has a clamping mechanism for fixing one or more winding tubes.

  In order to deliver the bobbin or the wound tube held by the swivel arm, the swivel arm has a push-off mechanism, and the push-off mechanism holds the bobbin and / or the wind tube movably along the swivel arm in the axial direction. Is particularly advantageous. As a result, the bobbin is uniformly pushed away from the swivel arm at the transfer position of the swivel arm and directly delivered to the bobbin receiving station. Similarly, the winding tube or tubes held on the swivel arm are continuously moved and supplied to the receiving position of the standby winding spindle.

  It is particularly advantageous that the pushing / separating mechanism comprises a pushing member and a linear drive device. In this case, the push member is guided along the swivel arm, and the linear drive device is arranged in the axial extension of the swivel arm. Thereby, the space required by the swivel movement of the swivel arm can be exploited to receive additional devices. Furthermore, in this case, it is possible to compensate the weight of the swing arm on the swing axis.

  The apparatus according to the invention is particularly suitable for removing full tube bobbins that occur regularly in a continuous winder and delivering them to a bobbin conveying device. In this case, the number of bobbins wound up by the winding spindle is irrelevant. The device of the invention is therefore also suitable for receiving only one bobbin per take-up spindle or for receiving multiple bobbins per take-up spindle.

  Hereinafter, the present invention will be described in detail based on some embodiments shown in the accompanying drawings.

  1 and 2 show a first embodiment of the device according to the invention as seen from different directions. The embodiment is shown in side view in FIG. 1 and in plan view in FIG. As far as this is concerned, the following description relating to one drawing applies to both drawings.

  The device according to the invention comprises a plurality of pivot arms 4.1 and 4.2, which pivot arms 4.1 and 4.2 each have one holding end 8 and one free mating end 9. And have. The pivot arms 4.1 and 4.2 are connected to the pivot shaft 5 at the holding end 8. The swivel shaft 5 is horizontally oriented and is rotatably supported by the holding body 6. In this embodiment, the pivot shaft 5 is supported in a cantilever manner. In this case, the swivel arms 4.1 and 4.2 are fixedly coupled to the swivel shaft 5 at the free end of the swivel shaft 5. At the opposite end, the swivel shaft 5 is connected to a rotary drive device 7, by which the swivel shaft 5 rotates in the clockwise and counterclockwise directions with the swivel arms 4.1 and 4.2. Can be made. In this case, the swivel arms 4.1 and 4.2 move in a vertically oriented guide plane. In FIG. 1, the guide plane is shown in the figure plane. In FIG. 2, the guide plane is shown in the section of the swivel arm 4.1.

  A winder 1 is arranged on the sides of the swivel arms 4.1 and 4.2. The winder 1 has a plurality of winding spindles 2.1 and 2.2 held by a movable spindle holder 25. The spindle holder 25 is movably supported on the machine frame 26, so that the winding spindles 2.1 and 2.2 are alternately wound into a winding area for winding the bobbin and an exchange area for removing the finished bobbin 3. Guided. Such winders are generally known and are described, for example, in EP 374536 B1. Insofar as the details of the configuration and function of the winder are not described in the description of the present application, reference is made to the incorporated EP 374536B1.

  The swivel arms 4.1 and 4.2 are held in front of the winder so that the take-up spindle 2.1 guided to the exchange area is aligned and facing one swivel arm 4.1 in the removal position. ing. By rotating the swivel shaft 5, one swivel arm 4.1 or swivel arm 4.2 is selectively positioned immediately before the take-up spindle 2.1 in the removal position.

  A winding tube supply device 17 is disposed above the pivot shaft 5. The winding tube supply device 17 has one winding tube delivery station 18 per winder. This winding tube delivery station 18 has a guide tube 19 with an opening facing downwards in this embodiment. The guide tube 19 is disposed in the guide plane. In this case, the swivel arm 4.1 or 4.2 can be positioned directly below the guide tube 19 in the filling position. In this case, the pivot arms 4.1 and 4.2 are preferably held concentrically in the opening formed by the guide tube 19. The guide tube 19 is connected to the winding tube magazine 20 in the upper region. The winding tube magazine 20 holds a large number of winding tubes 27. The winding tube magazine 20 has a guide member 21 capable of guiding each one of the winding tubes 27 into the guide tube 19.

  A bobbin transport device 10 is configured on the side of the turning shaft 5 opposite to the winder 1. The bobbin conveying apparatus 10 has a bobbin receiving station 11, and a bobbin carriage 13 is positioned in the bobbin receiving station 11. The bobbin carriage 13 has a bobbin mandrel 12 that is disposed corresponding to the guide path between the swing arms 4.1 and 4.2 at the free end. The swivel arm 4.1 is guided to the delivery position by the rotation of the swivel shaft 5. At this delivery position, the swivel arm 4.1 and the bobbin mandrel 12 are substantially aligned in the axial direction and face each other.

  3 and 4 in addition to FIG. 1 are used to describe the function of the apparatus of the present invention. 3 and 4 show an embodiment of the device according to the invention in a modified operating position. In this case, FIG. 1 shows a state in which the bobbin starts to be removed, FIG. 3 shows a state in which the bobbin is delivered to the bobbin conveying device, and FIG. 4 shows a state in which a new winding tube is provided on an empty winding spindle. It is shown.

  In the case of the winding machine shown in FIG. 1, the winding spindle 2.1 is in the exchange position together with the bobbin 3 that has finished winding. The winding spindle 2.2 is in a winding position where the two supplied yarns are wound around the bobbin in parallel with each other. The winding spindle 2.1 in the winding area of the winding machine is not driven and is waiting for a bobbin exchange. For this purpose, the swivel shaft 5 guides and holds the swivel arm 4.1 directly facing the take-up spindle 2.1 in the take-out position. Subsequently, the bobbin 3 is pushed away from the take-up spindle 2.1 via a push-off device in the take-up spindle 2.1 and guided onto the swivel arm 4.1. This state is indicated by a broken line in FIG. After the bobbin 3 is held by the swivel arm 4.1, the rotation drive device 7 of the swivel shaft 5 is actuated to rotate in the clockwise direction, and the swivel arm 4.1 is brought out of the take-out position. The rotary drive 7 is operated until the swivel arm 4.1 reaches the opposite delivery position and faces the bobbin mandrel 12 of the bobbin receiving station 11. At that time, the swivel arm 4.1 moves corresponding to a rotation angle of about 180 °. The swivel arms 4.1 and 4.2 are fixed to each other and form an angle α in the region of 90 ° between them. As a result, simultaneously with the rotation of the swivel shaft 5, the swivel arm 4.2 is shifted 90 ° and swiveled in the clockwise direction.

  FIG. 3 shows a state after a rotation angle of 180 ° in the turning shaft 5. The swivel arm 4.1 is locked facing the bobbin mandrel 12 at the delivery position. In this state, the swivel arm 4.2 is held immediately below the winding tube delivery station in the filling position. Two winding tubes 27 are sequentially held on the swing arm 4.2 via the guide tube 19. The second winding tube 27 is guided from the winding tube magazine 20 into the guide tube 19 by the guide member 21. Within the guide tube 19, the winding tube 27 falls by its gravity directly onto the exiting opening of the guide tube 19 onto the waiting swivel arm 4.2.

  At the same time, the bobbin 3 in the swing arm 4.1 is delivered to the waiting bobbin mandrel 12. After the bobbin 3 is delivered to the bobbin mandrel 12, the rotation driving device of the turning shaft 5 is actuated again, and the turning shaft 5 rotates about 90 ° counterclockwise. In this case, the swivel arm 4.2 is brought together with the winding tube 27 from the filling position to the receiving position.

  In the receiving position, the pivot arm 4.2 is axially aligned with the take-up spindle 2.1 as shown in FIG. The winding tube 27 can now be transferred from the swivel arm 4.2 to the winding spindle 2.1. Thereby, the bobbin replacement in the winder 1 is completed. The swivel arms 4.1 and 4.2 are brought into a starting state as shown in FIG. 1 by rotating the swivel shaft 5 by the operation of the rotary drive device 7. The bobbin in the bobbin mandrel 12 is carried out by the bobbin carriage 13.

  In the embodiment shown in FIGS. 1 to 4, the guide planes of the swivel arms 4.1 and 4.2 are oriented vertically, so that even in the case of a large number of bobbins, the bobbins can be mounted in the narrowest space. It can be brought from the winder to the bobbin conveying device. In this case, the swivel arm needs to have dimensions corresponding to the bobbin width. The configurations of the winding tube supply device 17 and the bobbin transport device 10 arranged corresponding to the swivel arm are exemplary. In principle, a system capable of supplying a wound tube or receiving a bobbin is suitable. Thus, for example, the bobbin mandrel 12 can be guided and positioned by a suspension path or other transport means.

  5 and 6 show another embodiment of the device according to the invention in a schematic side view in multiple operating states. The following description applies to both FIG. 5 and FIG. 6 unless otherwise noted for either FIG. 5 or FIG.

  The embodiment shown in FIGS. 5 and 6 is substantially the same as the embodiment of FIG. Therefore, only the differences will be explained below, and the others should be referred to the above description.

  In the device shown in FIGS. 5 and 6, the pivot arms 4.1 and 4.2 are held on the pivot shaft 5 while being shifted from each other by an angle α. The swivel arms 4.1 and 4.2 are driven in the clockwise direction and the counterclockwise direction by rotating the swivel shaft 5. The pivot shaft 5 is connected to a rotary drive device (not shown) and is supported on the holding body in a cantilever manner or on both sides.

  The swivel arms 4.1 and 4.2 each have a pushing mechanism 22. The pushing / separating mechanism 22 is formed by a pushing member 23 and a linear drive device 24. The push member 23 is guided as a ring, for example, on the peripheral surface of each of the swivel arms 4.1 or 4.2. A linear drive 24, for example a pneumatic cylinder, is arranged in the axial extension of each swivel arm 4.1 or 4.2, the linear drive 24 being substantially in the guide plane with respect to the swivel axis 5 with respect to the swivel arm 4. .1 on the opposite side. This arrangement has the particular advantage that a symmetrical arrangement with respect to the pivot axis 5 is obtained and the weight is compensated for the pivot axis 5. Therefore, the rotational moment required to operate the pivot 5 is limited to the load provided by the bobbin. The linear drive devices 24 of the swivel arms 4.1 and 4.2 are arranged with respect to each other such that the respective pushing members 23 of the swivel arms 4.1 and 4.2 can be actuated individually and independently of each other.

  A winder 1 is arranged on one side of the swivel arms 4.1 and 4.2. The winder 1 has a spindle holder 25 movably held on a frame wall 28. The spindle holder 25 holds two take-up spindles 2.1 and 2.2 held in a cantilever manner, and each take-up spindle 2.1 and 2.2 holds and winds one bobbin. For this purpose, the take-up spindles 2.1, 2.2 are alternately brought into the take-up area and the exchange area by the spindle holder 25. In the state shown in FIG. 5, the winding spindle 2.1 is held in the exchange position together with the bobbin 3.

  On the opposite side of the winder 1, two swivel arms 4.1 and 4.2 are associated with two bobbin receiving stations 11.1 and 11.2 of the bobbin transport device. The first bobbin receiving station 11.1 has a bobbin chute 15 for receiving a bobbin pushed away from the swivel arm 4.1. The bobbin chute 15 is held laterally with respect to the swivel arms 4.1 and 4.2. The second bobbin receiving station 11.2 is configured on the floor immediately before the winder 1. In this case, the bobbin receiving station 11.2 is formed by a container 29 which receives the released bobbin from one pivot arm 4.1 or 4.2. The bobbin receiving station 11.2 is provided, for example, for receiving defective bobbins that do not have sufficient bobbin diameter or do not have sufficient yarn quality. In this case, the container 29 can be guided manually or automatically by a conveyor belt.

  On the upper side of the swivel arms 4.1 and 4.2 in the guide plane, a winding tube supply device 17 is configured. In this embodiment, only the guide tube 19 for supplying the winding tube is shown.

  Since the functions of the embodiment shown in FIGS. 5 and 6 are almost the same as those of the previous embodiment, only the differences will be described and the rest will be left to the previous description.

  FIG. 5 shows a state in which the swivel arm 4.1 is positioned immediately before the winding spindle 21 in the receiving position. After delivering the bobbin 3 from the take-up spindle 2.1, the pivoting arm 5 is actuated to pivot the pivot arms 4.1 and 4.2 in the clockwise direction. Depending on the quality of the bobbin, the swivel arm is swiveled by a rotation angle of 180 ° or 270 °. In the case of a defect-free bobbin, the swivel arm 4.1 is brought to the delivery position reached after 180 °. Then, the push-off mechanism 22 in the swing arm 4.1 is actuated so that the bobbin 3.1 is pushed away beyond the free end of the swing arm 4.1 and automatically guided onto the bobbin chute 15. This state is shown in FIG. At the same time, the winding tube 27 is supplied to the swivel arm 4.2 held in the filling position.

  If the bobbin 3 removed from the winding spindle 2.1 is defective, the pivot shaft 5 is pivoted clockwise by a pivot angle of 270 ° in order to move the pivot arms 4.1 and 4.2. . Alternatively, the swivel arm 4.1 can be positioned in a decisive delivery position for the bobbin receiving station 11.2 by 90 ° in the counterclockwise direction of the swivel axis 5. After reaching the delivery position, the bobbin is delivered to the bobbin receiving station 11.2 and eventually the bobbin 3 is guided to the container 29. This state is not shown.

  The installation of the new winding tube 27 on the empty winding spindle 2.1 takes place in the same way as in the previous embodiment, so that the pivot arm 4.2 is brought from the filling position to the receiving position. In order to push away the winding tube 27, the push-off mechanism 22 in the turning arm 4.2 is operated.

  The embodiment shown in FIGS. 5 and 6 is particularly suitable for performing bobbin quality screening. Thus, all bobbins with sufficient A quality can be fed directly to the bobbin chute where they can be received and packaged directly. In contrast, so-called B-quality bobbins are sent to the container 29 and excluded.

  FIG. 7 shows a schematic side view of another embodiment of the device according to the invention. Since this embodiment is almost the same as the embodiment shown in FIGS. 5 and 6, only the differences will be described below, and the other descriptions should be referred to the previous description.

  In the embodiment shown in FIG. 7, the swivel arms 4.1 and 4.2 are held together on the swivel shaft 5 and are actively moved by the rotary drive device in the clockwise and counterclockwise directions. Can be made. A clamp mechanism 14 is arranged corresponding to the pivot arm 4.1, and the clamp mechanism 14 has a plurality of clamp bodies distributed on the outer periphery of the pivot arm 4.1. These clamping bodies are operable to grip a bobbin held on the circumferential surface of the swivel arm 4.1 by a compressed air piston guided inside the clamping body. For this purpose, the compressed air connection 31 is arranged corresponding to the swivel arm 41. On the other hand, the turning arm 4.2 has a push-off mechanism 22, which is formed by a push member 23 and a linear drive device 24. The swivel arms 4.1 and 4.2 have a winding tube supply device 17 on the upper side in the guide plane and a bobbin conveying device 10 on the floor. In this case, the bobbin receiving station 11 of the bobbin conveying device 10 is formed by a conveying belt 16, and the conveying belt 16 has a plurality of protruding bobbin mandrels 12. The bobbin mandrel 12 projects vertically upwards and is axially aligned at the bobbin receiving station 11 with the swivel arm 4.2 held in the delivery position.

  In the embodiment shown in FIG. 7, after one bobbin has been delivered from the take-up spindle 2.1 to the swivel arm 4.1, the swivel shaft 5 turns counterclockwise and the swivel arm 4.1 turns 90 °. Is pivoted until it is turned and brought to the delivery position. During this time, the clamping mechanism 14 of the swing arm 4.1 is operated, so that the bobbin 3 is held immovably by the swing arm 4.1. When the swivel arm 4.1 reaches the upper delivery position of the bobbin mandrel 12, the clamping mechanism 14 is released and the bobbin 3 slides along the swivel arm 4.1 and automatically centers through the bobbin mandrel 12. Then, it falls onto the conveyor belt 16. The bobbin 3 is discharged by the conveyor belt 16. At the same time, the winding spindle 2.2 is equipped with a winding tube 27 with a second swivel arm 4.2. For this purpose, the push-off mechanism 22 in the swivel arm 4.2 is operated, so that the winding tube 27 is scraped off from the swivel arm 4.2 in a uniform motion and guided to the take-up spindle 2.1. After the winding tube 27 is held on the winding spindle 2.1, the swivel arms 4.1 and 4.2 are swung clockwise by 90 °, so that the swivel arm 4.2 is in the filling position and the swivel arm 4 .1 is locked in the receiving position. In this case, the swivel arm 4.2 is equipped with a new winding tube 27 directly after reaching the filling position.

  In the previously described embodiment, each bobbin removal device is shown with two pivot arms. Basically, in the present invention, the number of swivel arms that can swivel about the swivel axis 5 is not limited to two. Three or four pivot arms can also be used to perform bobbin removal and winding tube installation. Furthermore, there is a possibility that the swivel arms are arranged on vertical guide planes oriented parallel to each other so that the swivel arms are also displaced in the axial direction and held on the swivel axis. Thus, two different positions of the take-up spindle can be used to push the bobbin away from the take-up spindle and to insert the winding tube into the take-up spindle. This is particularly advantageous if the winding spindle moves on one swivel circle during the normal winding process and is stopped only for bobbin replacement. In this case, the take-up spindle stop time can be divided into two small time zone segments. Similarly, the device of the present invention is not limited to having a take-up spindle oriented horizontally to receive a bobbin. Thus, a vertically oriented winding spindle is also possible. In this case, the swivel arm is advantageously guided under the take-up spindle so that the bobbin does not have to be released. The reason is that the full bobbin automatically moves onto the swivel arm. It is further noted that the device according to the invention is connected to a control device, which recognizes the individual operating states via sensors and thus performs a swivel movement of the swivel arm. However, the device of the present invention can also be manually operated to perform bobbin removal.
