Spooling device, rope-making machine and use of a spooling device

Description

[0001] The present invention relates to a spooling device for stranded material, comprising a rotatably mounted receiving device for a spool, a knock-off bracket for removing the stranded material from the spool, wherein the knock-off bracket is rotatably mounted such that it rotates around the spool for removing the stranded material, and a frame on which the receiving device and the knock-off bracket are arranged, the frame comprising a first frame part and a second frame part. The invention further relates to a stranding machine with at least one spooling device and the use of a spooling device for a stranding machine.

[0002] Within the scope of the present invention, stranded materials include, for example, metallic strand-like materials, such as, in particular, wires or cables, which are stranded together to produce more complex cables. For stranding such materials, basket stranding machines are known, for example, which allow stranding with a reverse twist, in which the individual wire or cable strands in the produced cable exhibit virtually no torsional stress. Cables produced in this way are particularly suitable for applications in which the cables must be moved continuously. In basket stranding machines, spools containing the starting material are arranged in a large, rotatably mounted basket. This results in low processing speed, high energy consumption, and time-consuming spool replacement. Furthermore, adapting the machine to different quantities of cable strands to be processed is difficult or impossible.In these machines, the material is removed via the side surfaces of the machines.

[0003] Stranding machines or unwinding devices are also known in which cable strands are unwound from the ends of spools. Higher production speeds are possible with these machines, but the torsional stresses in the stranded material caused by this unwinding method can be problematic. The stranding machine disclosed in DE 10 2012 108 475 A1 attempts to solve this problem by synchronizing the unwinding arms rotating around the unwinding spools with the winding arm rotating around a winding spool. However, the disclosed machine cannot be adapted to different quantities of strands being processed, and it is unclear what production speed is possible with the stranding machine and what effort is required to exchange or rewind the unwinding spools.

[0004] From GB 2 119 420 A, a spooling device is also known in which stranded material is unwound from the end of a spool. A movable frame part of the spooling device makes it possible to maintain a substantially constant unwinding angle of the stranded material. The unwound stranded material can be stranded with another strand that is guided through the device along a rotational axis of the spool. The continuous movement of the spool during the unwinding process over the movable frame part leads to limitations in the spool's bearings. This limits the achievable unwinding speeds.

[0005] The object of the present invention is to eliminate the disadvantages known from the prior art.

[0006] The problem is solved by a spooling device, a stranding machine and the use of a spooling device with the features of the independent claims.

[0007] A spooling device for stranded material is proposed, comprising a rotatably mounted receiving device for a spool and a disengaging bar for removing the stranded material from the spool. The disengaging bar is rotatably mounted such that it rotates around the spool to remove the stranded material. The spooling device includes a frame on which the receiving device and the disengaging bar are arranged, the frame comprising at least a first frame part and a second frame part. The receiving device is arranged between the first and second frame parts, the first frame part and / or the second frame part being axially movable along the frame. According to the invention, it is proposed that the first frame part and the second frame part each have a bearing point for the receiving device.

[0008] Unlike a holding device supported on only one side of the frame, a holding device with two bearing points can be operated at higher speeds under stable conditions. Since the first and / or second frame section is axially movable, a spool can still be easily replaced. During a spool replacement, the holding device is temporarily supported on only one side, for example. The holding device can be removed from at least one of the bearing points by moving the first and / or second frame section. The bearing points are formed, for example, by rotary bearings for the holding device.

[0009] A relative movement between the first and second frame sections facilitates, in particular, the easy exchange of a spool being unwound on the unwinding device. Furthermore, the unwinding device can be adapted to spools of varying widths. Depending on the distance between the disengagement bracket and the receiving device, spools of different diameters can also be used in the unwinding device. The receiving device is designed, in particular, as a shaft onto which a spool can be mounted and with which the spool can be clamped to transmit torque. During the axial movement of a frame section, a relative movement also occurs between the receiving device and at least one of the frame sections. In this context, the axial direction is essentially parallel to the common axis of rotation of the receiving device and the disengagement bracket.

[0010] The disengagement arm includes, for example, a roller that serves to deflect the stranded material after it has been unwound from a spool. When the device is used as intended, the roller is positioned, for example, essentially centrally to the receiving device. In its intended use, the disengagement arm specifically encompasses the spool being unwound, with one part of the arm serving to deflect the stranded material. Another part of the disengagement arm may include a counterweight that prevents uneven centrifugal forces or imbalances in the disengagement arm. In common technical usage, the disengagement arm is also often referred to by the English term "flyer."

[0011] An advantageous embodiment of the unwinding device provides that the unwinding device has a passage for guiding stranded material through it, which is arranged concentrically to a common axis of rotation of the receiving device and the discharging arm, wherein the passage has several separate guide areas for the stranded material. The passage allows several of the unwinding devices according to the invention to be modularly assembled into a stranding machine. The unwinding devices can, for example, be arranged one after the other, with the stranded material unwound from one of the unwinding devices being guided through the passage of the subsequent unwinding device. Each strand of stranded material from one unwinding device is guided, for example, through a separate guide area of ​​the passage of one of the subsequent unwinding devices.By synchronizing the rotations of the guide sections and the discharge brackets or receiving devices of the individual unwinding units, a reverse rotation of the stranded material can also be achieved. The separate guide sections of the last unwinding unit in such a sequence can also fulfill the function of a stranding pulley.

[0012] It is conceivable that a cable core, for example made of a plastic rod, is guided through the center of the opening. Alternatively, pre-stranded cable sections can be guided through the opening. Depending on the number of unwinding devices used, cables with any number of conductors or strands can be produced. In particular, one of the guide sections can be located precisely in the center of the common axis of rotation. Further guide sections can be arranged concentrically around the axis of rotation with the same radius. It is also conceivable that guide sections are arranged at different radial distances from the axis of rotation. The guide sections can have different diameters. For example, a guide section located centrally on the axis of rotation can have a larger diameter than the guide sections that are spaced further away from the axis of rotation.

[0013] It is advantageous if the receiving device is hollow, with the passage passing through it. This allows the stranded material to be guided close to the axis of rotation of the receiving device and the discharge arm. On the one hand, this avoids unnecessary stress on the stranded material caused by additional deflections. On the other hand, a stranding machine with several spooling devices arranged in series, as described above, can be arranged in a space-saving manner, at least in terms of width. Furthermore, reversing the stranded material is easier when guided close to the axis of rotation. The stranded material, guided by the receiving device in the separate guide sections, is rotated around the axis of rotation of the spool at the speed of the spool itself.

[0014] It is advantageous if the receiving device is designed as a hollow shaft or at least includes a quill. Using a hollow shaft is a technically simple way to implement the hollow receiving device. The advantages of a hollow receiving device have already been described. Another possibility is the use of quills. A quill is a hollow shaft, usually designed to perform axial movement. The receiving device can, for example, have two opposing quills that are inserted into the two opposite openings of the coil to receive it. Thus, a pair of quills does not form a continuous shaft, but rather two opposing shaft sections. This can simplify coil replacement. However, the stability of the receiving device may be lower in this case than, for example, when using a hollow shaft.

[0015] Furthermore, it is advantageous if at least a subset of the guide areas is arranged radially spaced from the common axis of rotation. As already described, it is advantageous to guide the stranded material being fed through the unwinding device close to the axis of rotation. Guide areas arranged radially spaced from the axis of rotation can be used for stranding the material, similar to a stranding pulley. As already described, in particular, a guide area can be arranged directly on the axis of rotation. Different subsets of the guide areas can also be arranged at different distances from the common axis of rotation.

[0016] It is also advantageous if the maximum relative travel of the frame components is greater than or equal to the width of a spool suitable for the unwinding device. This allows for the easy replacement of a spool on the receiving device with another. To replace the spool, the frame components move apart, allowing the spool to be moved off the receiving device in at least one direction. Lighter spools can be replaced by an operator, while heavier spools can be placed on the unwinding device by a forklift, for example. After replacing the spool, the frame components can be moved back to their initial position, so that the receiving device is once again supported at two points.The relative travel distance of the frame components can consist of the travel distance of one of the frame components or of a combined travel distance of both frame components. It is conceivable that the first and / or the second frame component is moved by an operator of the dispensing device. However, it is also conceivable that the dispensing device has a drive for the first and / or the second frame component. The first and / or the second frame component is preferably arranged on a rail system that allows for low-friction axial movement of the first and / or second frame component.

[0017] It is advantageous if the holding device is axially fixed to the first or second frame part. A fixed bearing point is easier to design and provides increased stability to the holding device. When changing the spool, the spool can be removed from the free end of the holding device opposite the fixed bearing point. In particular, the holding device is fixed to the first frame part, with the second frame part being axially movable. Of course, the holding device can also be fixed to the second frame part, with the first frame part being axially movable.

[0018] Alternatively, it is also advantageous if the mounting device is designed to be movable relative to the frame. The movable mounting device can also facilitate easy coil replacement. To replace a coil, for example, the mounting device can be moved out of the coil opening. This was already mentioned in connection with the use of quills. In this case, at least one of the quills holding the coil is designed to be axially movable, so that it can be extended out of the coil opening to change the coil. Of course, both quills holding the coil can also be movable. Even when using a continuous shaft, changing the coil by moving the mounting device is possible. In this case, the shaft has no fixed bearing point and is completely extended out of the coil for a coil change.The first frame part and the second frame part, for example, are not axially movable, i.e., static.

[0019] It is advantageous if the disengagement lever is arranged on either the first or the second frame section. The position of the disengagement device is unaffected by which frame section the disengagement lever is located. If the disengagement lever and the receiving device are driven by a common drive, it may be advantageous for the disengagement lever to be arranged on the frame section in which the drive is also located. If the disengagement lever has its own drive, it may be advantageous for the disengagement lever to be positioned opposite a drive of the receiving device. For easier spool replacement, it may be advantageous for the disengagement lever to be arranged on the frame section that is axially movable.

[0020] It is also advantageous if the receiving device is connected to a first drive for rotating the receiving device. The receiving device can thus be driven by its own drive for the unwinding device. A coil to be unwound by the unwinding device is connected to the receiving device in a torque-transmitting manner and is also set in rotation by the rotation of the receiving device. An individual rotational speed of the receiving device can be set, for example, depending on the mass and winding condition of the coil being received. The drive can be designed, in particular, as an electric motor. The receiving device can be connected to the drive, for example, via a belt. It is conceivable to provide a transmission between the drive and the receiving device.

[0021] It is advantageous if the disengagement lever includes a braking device for controlled deceleration. The disengagement lever can, for example, be driven solely by the stranded material being pulled from the spool. In this case, the disengagement lever is not connected to a drive. The braking device still allows the disengagement lever to rotate at a well-defined speed and, for example, to be synchronized with other rotating components.

[0022] Furthermore, it is advantageous if the disengaging lever is connected to the first drive for rotating the disengaging lever during the unwinding operation of the unwinding device. The receiving device and the disengaging lever can thus be driven by a common drive. In particular, this ensures that the receiving device and the disengaging lever rotate at the same speed during the unwinding operation. The disengaging lever and the receiving device are connected, in particular, by a torque-transmitting gear element. This gear element can, for example, be detachably designed in the case of a movable first frame section and / or second frame section.

[0023] It is also advantageous if the disengaging lever is connected to a second drive for rotating the disengaging lever. This allows the rotation of the disengaging lever to occur completely independently of the rotation of the receiving element or the spool. A torque-transmitting connection between the receiving element and the disengaging lever is not necessary in this case. The rotation of the receiving element and the disengaging lever can be controlled independently of each other. In particular, the rotation of the disengaging lever of one unwinding device can be easily synchronized with the rotation of the disengaging lever of another unwinding device. The rotation of the disengaging lever can also be synchronized with the rotation of a stranding pulley or with the rotation of a disengaging lever of a winding device.

[0024] It is also advantageous if the disengagement bracket includes a guide for the stranded material, designed to guide the material to the passage. As already described, it is advantageous to guide the stranded material through the unwinding device close to the common axis of rotation of the disengagement bracket's receiving device. To guide the stranded material in the direction of the axis of rotation, the disengagement bracket has the described guide. For this purpose, the passage has an opening, particularly in the area of ​​the disengagement bracket's axis of rotation, through which the stranded material unwound from the unwinding device can enter one of the guide areas. The guide can, for example, be designed as a cavity in the disengagement bracket.

[0025] Furthermore, it is advantageous if at least a subset of the guide areas extends continuously through the entire passage and / or at least a subset of the guide areas are arranged section by section within the passage. Continuous design in this context means that the guide areas extend uninterrupted across the entire unwinding device. In other words, the guide areas have no connection to each other across the entire unwinding device. Alternatively, the passage can be designed as a continuous cavity with section by section featuring guide elements with the described guide areas. These guide elements can be designed similarly to stranding pulleys. The stranded material, or the various strands of stranded material, which are unwound, for example, from different unwinding devices of a stranding machine, run between the guide elements in the common cavity of the passage.The guide elements can be arranged, for example, at an entrance to the passage, at an exit of the passage, and / or at a bearing of the discharge arm. The bearing of the discharge arm is located, for example, where the stranded material pulled off the discharge arm enters the passage. In any case, the passage, or at least one guide area, must have at least one radial opening so that the stranded material unwound from the unwinding device can enter one of the guide areas.

[0026] The stranding machine according to the invention comprises at least one unwinding device and is characterized in that the at least one unwinding device is designed according to the preceding description. The described features of the unwinding device can be implemented individually or in any combination. By using the unwinding devices according to the invention, the stranding machine can be designed modularly, depending on how many strands of stranded material are to be stranded to form the desired product. Furthermore, as already described, stranding with a reverse twist of the stranded material is easy to implement. The stranding machine also includes, for example, a winding device for winding the stranded material. The stranding machine can also include, for example, a stranding nozzle. Stranded material includes, for example, all types of wires, strands, or cables made of metal.Stranded goods also include non-metallic stranded materials, such as nylon strands, from which ropes are made, for example.

[0027] It is also advantageous if the stranding machine has a stranding pulley and a third drive for rotating the pulley. The stranding pulley with its own drive enables the controlled stranding of multiple strands of material. For this purpose, the stranding pulley typically has several guide areas for the different strands. The third drive allows the rotational speed of the stranding pulley to be synchronized, for example, with the rotational speeds of the disengagement arms and / or the receiving devices of the upstream unwinding units. The stranding pulley simplifies the operation of the stranding machine and improves the quality of the stranding. The stranding pulley can, for example, be connected to the third drive by means of a belt.

[0028] It is advantageous if the stranding machine has at least two unwinding devices, the unwinding devices being oriented such that their axes of rotation lie on a common line. As already described, the stranding machine can thus be modularly adapted to the number of strands of material to be stranded. The strands of material from upstream unwinding devices are guided through the separate guide sections of the downstream unwinding devices. Further advantages include the reverse rotation of the material during stranding and the possibility of high operating speeds thanks to the unwinding devices. Naturally, the stranding machine can have any number of unwinding devices.However, the unwinding devices do not need to be permanently connected to each other, but can be easily rearranged or assigned to other stranding machines at later times.

[0029] It is also advantageous if the stranding machine has a control system designed to control the third drive in such a way that the rotational speed of the stranding pulley matches the rotational speed of the unwinding device's discharge arm, or the rotational speeds of the discharge arms of the various unwinding devices. The control system can, for example, be integrated into one of the unwinding devices. It is also conceivable that an external control system is connected to the unwinding devices and the third drive. In this case, the control system could, for example, be integrated into a computer system.

[0030] The invention also proposes the use of a spooling device for a stranding machine. The spooling device is designed according to the preceding description, whereby the described features can be implemented individually or in any combination. The stranding machine is also designed according to the preceding description, whereby the described features can likewise be implemented individually or in any combination. The use of the spooling devices according to the invention enables the production of stranded products at a high operating speed, with a modular design depending on requirements, and with the possibility of rewinding the stranded material during the stranding process.

[0031] In a process for stranding stranded material, the material is unwound from several sequentially arranged unwinding devices and stranded together. The material from upstream unwinding devices is guided through a passage of downstream unwinding devices. The rotational speeds of the disengaging arms of all unwinding devices are synchronized.

[0032] Upstream and downstream here refer to any point in the series of unwinding devices, except for the first unwinding device in the series. The method is particularly suitable for operating the stranding machine according to the invention. The features of the stranding machine and the unwinding device already described can also characterize the method according to the invention and can be implemented individually or in any combination.

[0033] In this method, the unwinding devices can, for example, be arranged coaxially in a row without any additional deflection of the stranded material. This is made possible in particular by the compact design of the unwinding machine according to the invention.

[0034] Further advantages of the invention are described in the following exemplary embodiments. These show: Figure 1 a schematic side view of a spooling device according to the invention in a spooling position, Figure 2 a schematic front view of the unwinding device according to the invention, Figure 3 a schematic side view of a further embodiment of the unwinding device according to the invention in a spool change position Figure 4 a schematic side view of a further embodiment of the unwinding device according to the invention in a spool change position, and Figure 5 a schematic side view of a stranding machine according to the invention.

[0035] In the following description of the figures, the same reference symbols are used for features that are identical and / or at least comparable in the various figures. The individual features, their design, and / or mode of action are usually only explained in detail upon their first mention. If individual features are not explained again in detail, their design and / or mode of action corresponds to the design and mode of action of the already described features with the same or identical effect.

[0036] Figure 1Figure 1 shows a schematic side view of a winding device 1 according to the invention for stranded material 2. A spool 3 is arranged on a rotatably mounted receiving device 4. For unwinding the stranded material 2 from the spool 3, the winding device 1 has a knock-off bracket 5, the knock-off bracket 5 being mounted such that it rotates around the spool 3 to unwind the stranded material 2. The winding device 1 comprises a frame 6 on which the receiving device 4 and the knock-off bracket 5 are arranged. The frame 6 in turn comprises a first frame part 7 and a second frame part 8. A passage 9 through the winding device 1 for guiding stranded material 2 is shown in dashed lines; this passage is arranged concentrically to a common axis of rotation 10 of the receiving device 4 and the knock-off bracket 5.

[0037] Passage 9 includes several separate guide areas 11 for stranded goods 2 (see Figure 2This example illustrates how stranded material 2 is guided from the spool 3 via the disengagement arm 5 to the passage 9. For this purpose, the disengagement arm 5 has a guide 12, also shown with dashed lines. The stranded material 2 is then guided out of the unwinding device 1 close to the common axis of rotation 10. To set the spool 3 into rotation, the unwinding device 1 includes a first drive 13 for rotating the receiving device 4. In this example, the receiving device 4 is connected to the first drive 13 via a belt 14. In this example, the disengagement arm 5 is driven solely by the stranded material 5 being pulled from the spool 3. For precise control of the rotation and, in particular, the speed, the disengagement arm 5 includes a braking device 15 in this case. Depending on the design of the disengagement arm 5, spools 3 with different diameters can be inserted into the unwinding device 1.In the present illustrations, a coil 3 with the maximum possible diameter is inserted into the unwinding device 1. Coils 3 with smaller diameters can, of course, also be used. Naturally, the unwinding device 1 can also be designed for larger coil diameters by modifying the design of the disengaging lever 5.

[0038] The guide areas 11 can, for example, be formed essentially continuously through the entire passage 9, preferably with an opening to guide the stranded material 2 unwound from the spool 3 into one of the guide areas 11. Alternatively, the guide areas 11 can be arranged only in sections within the passage 9. A subset of the guide areas 11 can, for example, be arranged at an inlet 26 of the passage 9, at an outlet 27 of the passage 9, and / or at a bearing 28 of the disengagement bracket 5. The stranded material 2 can, for example, run between these sections of the guide areas 11 in the common passage 9.

[0039] In this example, the receiving device 4 is arranged on the first frame part 7, and is in particular axially fixed to the first frame part 7. The knock-off bracket 5 is arranged on the second frame part 8. The receiving device 4 is arranged between the first frame part 7 and the second frame part 8, with the first frame part 7 and the second frame part 8 each having a bearing point 16 for the receiving device 4. The receiving device 4 is hollow and in particular designed as a hollow shaft. The passage 9 leads through the receiving device 4. One or both of the frame parts 7, 8 can be arranged as shown in Figure 3 The structure is designed to be axially movable along the frame 6.

[0040] Figure 2Figure 1 shows a schematic front view of the unwinding device 1 from Figure 1. The view of the passage 9 is shown enlarged. The separate guide areas 11 of the passage 9 are clearly shown. A larger guide area 11 is arranged precisely on the common axis of rotation 10 of the receiving device 4 and the discharge bracket 5. However, a subset of the guide areas 11 are also arranged at a distance from the common axis of rotation 10. In this case, guide areas 11 are arranged at different distances from the common axis of rotation 10. This allows, in principle, the stranding of stranded material 2 in different planes. The guide area 11 arranged on the axis of rotation 10 is, for example, for guiding a cable core 17 (see Figure 1). Figure 5 ), which consists, for example, of a pre-stranded cable or a stable plastic rod, is suitable.

[0041] During operation of the unwinding device 1, the guide sections 11, which are arranged at a distance from the axis of rotation 10, rotate about the common axis of rotation 10 at the speed of the receiving device 4 and / or the speed of the discharging arm 5. In this way, a reverse rotation of the stranded material 2 can be achieved. The guide sections 11, which are arranged at a distance from the axis of rotation 10, are particularly suitable for guiding strands of stranded material 2, which are unwound from unwinding devices 1 located upstream of the illustrated unwinding device 1, through the unwinding device 1 for subsequent stranding.

[0042] Figure 3Figure 1 shows a schematic side view of a further embodiment of the unwinding device 1 according to the invention. The unwinding device 1 is shown in a coil-changing position. The unwinding device 1 is open such that the coil 3 placed on the receiving device 4 can be easily removed and replaced with a new coil 3. In this example, the receiving device 4 is axially fixed to the first frame part 7. The second frame part 8 is designed to be axially movable along the frame 6. A maximum relative travel 18 of the frame parts 7, 8 is greater than or equal to the width 19 of the coil 3 arranged on the unwinding device 1. This allows the coil 3 to be pulled laterally off the receiving device 4. An empty coil 3 can thus be replaced, for example, by a full coil 3.

[0043] In this example, too, the receiving device 4 is designed as a hollow shaft. During the unwinding operation of the unwinding device 1, the receiving device 4 is supported in both the first frame part 7 and the second frame part 8, despite the mobility of the second frame part 8. In this case, the receiving device 4 can be removed from the bearing point 16 in the second frame part 8. During the unwinding operation, the receiving device 4 and the disengaging arm 5 can be connected to each other, for example, by positive locking elements, so that the disengaging arm 5 can also be driven by the first drive 13. A certain tolerance can be allowed here, so that coils 3 of different widths 19 can be inserted into the unwinding device 1.

[0044] Figure 4Figure 1 shows a schematic side view of another embodiment of the unwinding device 1 according to the invention, also in the coil-changing position. In this embodiment, the receiving device 4 comprises at least one quill 20. This allows the coil 3 to be changed in an even simpler manner. In the illustrated example, the coil 3 is held by another quill 20, which is not visible. In this embodiment, the knock-off lever 5 is connected to a second drive 21 for rotating the knock-off lever 5. Both the unwinding device 1 and the receiving device 4 comprise at least one quill 20. Figure 3 as well as the unwinding device 1 from Figure 4 can additionally the in Figures 1 and 2 The passage 9 shown has separate guide areas 11 for stranded material 2.

[0045] Figure 5Figure 1 shows a side view of a stranding machine 22 according to the invention, which comprises at least two unwinding devices 1. In the illustrated example, a cable core 17 is guided through the passages 9 of both unwinding devices 1. The stranding material 2 unwound from the unwinding devices 1 is guided in a separate guide area 11 within the passages 9. In this way, a stranding machine 22 can be modularly constructed for stranding a plurality of strands of stranding material 2 unwound by the unwinding devices 1. The stranding machine 22 comprises a stranding pulley 23, to which the strands of stranding material 2 are fed. Following the stranding pulley 23, the strands are stranded, for example, in a stranding nozzle (not shown).

[0046] The stranding pulley 23 is connected to a third drive 24, so that the stranding pulley 23 can be driven and controlled independently of the unwinding devices 1. However, to achieve reverse rotation of the stranded material 2, it is advantageous if the stranding pulley 23 runs synchronously with the receiving devices 4 and / or the discharging arms 5 of the unwinding devices 1. For this purpose, the stranding machine 22 has a control unit 25 which is connected to the drives 13, 21, 24 of the unwinding devices 1 and to the stranding pulley 23. The control unit 25 is configured to control the third drive 24 such that the rotational speed of the stranding pulley 23 corresponds to the rotational speeds of the discharging arms 5 of the unwinding devices 1. The first frame part 7 and / or the second frame part 8 of the frames 6 of the unwinding devices 1 can be designed to be axially movable, so that the coils 3 of the unwinding devices 1 can be changed in a simple manner.
