  • 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.
  • stranded materials include, for example, metallic strand-like materials, such as wires or cables, which are stranded together to produce more complex cables.
  • basket stranding machines are known, which allow stranding with a reverse twist, resulting in the individual wire or cable strands in the manufactured cable exhibiting virtually no torsional stress. Cables manufactured in this way are particularly suitable for applications where the cables must be moved continuously.
  • spools containing the starting material are arranged in a large, rotatably mounted basket. This results in low processing speeds, high energy consumption, and complex spool replacement.
  • adapting the machine to different quantities of cable strands to be processed is difficult or impossible. In these machines, the material is drawn off over the side surfaces of the machine.
  • Stranding machines or unwinding devices are also known in which cable strands are pulled off 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 pose a problem.
  • the [unclear text] DE 10 2012 108 475 A1 The disclosed stranding machine attempts to solve this problem by synchronizing the unwinding arms rotating around the unwinding spools with the winding arm rotating around a winding spool.
  • the disclosed machine cannot be adapted to different quantities of strands of stranded material 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.

  • a movable frame section 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 section leads to limitations in the spool's bearing arrangement. This limits the achievable unwinding speeds.
  • the object of the present invention is to eliminate the disadvantages known from the prior art.
  • a spooling device for stranded material 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.

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.
  • 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.

  • a relative movement also occurs between the receiving device and at least one of the frame components.
  • the axial direction is essentially parallel to the common axis of rotation of the receiving device for the striker.
  • the disengagement arm includes, for example, a roller that serves to deflect the stranded material after it has been unwound from a spool.
  • the roller When the device is used as intended, the roller is positioned, for example, essentially centrally to the receiving device.
  • 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.
  • the disengagement arm is also often referred to by the English term "flyer.”
  • 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 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.
  • 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. Stranded material guided by the receiving device in the separate guide areas is rotated around the axis of rotation of the spool, in particular at the speed of the spool.
  • the receiving device is designed as a hollow shaft or at least includes a quill.
  • a hollow shaft is a technically simple way to implement the hollow receiving device.

This allows for the simple 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 returned to their initial position, so that the receiving device is once again supported at two points.
