Definitions

  • the present invention relates to an unwinding device for stranded goods with a rotatably mounted receiving device for a spool, a knock-off bracket for pulling the stranded goods off the spool, wherein the knock-off bracket is rotatably mounted in such a way that it circles the spool for pulling the stranded goods off, a frame on which the receiving device and the knock-off bracket are arranged, wherein the frame comprises a first frame part and a second frame part.
  • the invention also relates to a stranding machine with at least one unwinding device, the use of an unwinding device for a stranding machine and a method for stranding stranded goods.
  • stranded goods include, for example, metallic strand-like materials, such as wires or cables in particular, which are stranded together to produce more complex cables.
  • basket stranding machines are known, for example, which allow stranding with a reverse twist in which the individual wire or cable strands in the cable produced have virtually no torsional stress. Cables produced in this way are particularly suitable for applications in which the cables must be constantly moved.
  • spools with the starting material are arranged in a large, rotatably mounted basket. This means that the processing speed is low, energy consumption is high, and replacing the spools is complex.
  • adapting the machine to different quantities of cable strands to be processed is difficult or impossible. In these machines, the material is drawn off via the side surfaces of the machines.
  • the object of the present invention is to eliminate the disadvantages known from the prior art.
  • the object is in particular to create an unwinding device which can be used modularly for a stranding machine and in which a spool exchange is possible in a simple manner.
  • a winding device for stranded goods is proposed with a rotatably mounted receiving device for a spool and a knock-off bracket for pulling the stranded goods off the spool.
  • the knock-off bracket is rotatably mounted in such a way that it circles the spool for pulling the stranded goods off.
  • the winding device comprises a frame on which the receiving device and the knock-off bracket are arranged, wherein the frame comprises at least a first frame part and a second frame part.
  • the winding device has a passage for guiding stranded goods through the winding device, which passage is concentric to a common axis of rotation of the receiving device and of the knock-off bracket, wherein the passage has a plurality of separate guide regions for stranded material.
  • the passage allows a plurality of the unwinding devices according to the invention to be modularly assembled to form a stranding machine.
  • the unwinding devices can be arranged one behind the other, for example, wherein the stranded material unwound from one of the unwinding devices is guided through the passage of the subsequent unwinding device.
  • One strand of stranded material from one unwinding device is guided, for example, through a separate guide region of the passage of one of the subsequent unwinding devices.
  • the stranded material can also be rotated backwards.
  • the separate guide regions of the last unwinding device in such a sequence can also fulfill the function of a stranding disk.
  • one of the guide areas can be located exactly in the middle of the common axis of rotation.
  • Other guide areas can be arranged concentrically around the axis of rotation with the same radius.
  • guide areas are arranged at different radial distances from the axis of rotation.
  • the guide areas can have different diameters. For example, a guide area arranged centrally on the axis of rotation can have a larger diameter than the guide areas that are arranged at a distance from the axis of rotation.
  • the receiving device is arranged between the first frame part and the second frame part, wherein the first frame part and/or the second frame part are designed to be axially movable along the frame.
  • a relative movement between the first frame part and the second frame part enables, in particular, a simple exchange of a spool that is unwound on the unwinding device.
  • the unwinding device can be adapted to spools of different widths. Depending on the distance between the knock-off 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 placed and with which the spool can be clamped to transmit a torque.
  • a relative movement also takes place between the receiving device and at least one of the frame parts.
  • the axial direction in this context is a direction essentially parallel to the common axis of rotation of the receiving device of the knock-off bracket.
  • the knock-off bracket comprises, for example, a roller that serves to redirect the stranded material after it has been drawn off a spool.
  • the roller is arranged essentially in the middle of the receiving device.
  • the knock-off bracket particularly encompasses the spool to be unwound, with one part of the knock-off bracket serving to redirect the stranded material.
  • Another part of the knock-off bracket can comprise a counterweight that prevents uneven centrifugal forces or imbalances in the knock-off bracket.
  • the knock-off bracket is often referred to by the English term flyer.
  • the receiving device is hollow, with the passage leading through the receiving device. This allows the stranded goods close to the rotation axis of the receiving device and the knock-off bracket. On the one hand, this avoids unnecessary stress on the stranded goods caused by additional deflections.
  • a stranding machine with several unwinding devices arranged one behind the other, as already described above can be arranged in a space-saving manner, at least in terms of width. Reverse rotation of the stranded goods can also be achieved more easily by guiding them close to the rotation axis.

  • the spool can be removed from the free end of the receiving device opposite the fixed bearing point.
  • the receiving device is firmly connected to the first frame part, with the second frame part being designed to be axially movable.
  • the receiving device can also be firmly connected to the second frame part, with the first frame part being designed to be axially movable.
  • the holding device is designed to be movable relative to the frame.
  • the mobility of the holding device can also contribute to an easy exchange of the coil.
  • the holding device can, for example, be moved out of the opening of the coil.
  • at least one of the sleeves that hold the coil is designed to be axially movable so that it can be moved out of the opening of the coil to change the coil.

  • the stranding machine 22 has a control 25 which is connected to the drives 13, 21, 24 of the unwinding devices 1 and the stranding disk 23.
  • the control 25 is designed to control the third drive 24 in such a way that a speed of the stranding disk 23 matches the speeds of the knock-off brackets 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 spools 3 of the unwinding devices 1 can be changed in a simple manner.
