Definitions

  • the present invention relates to a device for stranding strand-like material, in particular a larger cross-section with a changing direction of lay (SZ), consisting of a rotor rotating with an alternating direction of rotation and / or speed with two mutually opposite drive chains running parallel to the rotor axis along an endless path and on the Drive chains attached and driven by these, along a predetermined distance determined by a pressure rail to the stranded material comprising and guiding collets and then releasing the stranded collet halves.
  • SZ changing direction of lay
  • Such a device makes it possible to strand also wires of larger cross-sections, such as are necessary for the transmission and distribution of electrical energy, to form a cable core according to the SZ stranding method previously only used for communication cable wires.
  • the individual cores are combined into a bundle or bundle, held by the collets of the device and stranded during the holding along a certain distance by rotating the rotor with changing direction and / or speed.
  • the release of the stranded cores at the end of this path or storage path takes place by means of return springs assigned to each collet half.
  • EP-A-0 431 244 discloses a stranding machine with a stranding rotor, which is already described in DE-C-27 42 662, for the continuous stranding of electrical cables and lines, which takes place in alternating direction.
  • the stranding rotor is designed as a structural unit in the stranding machine and is interchangeably mounted with respect to the drive.
  • US-A-1,865,362 describes an apparatus for compacting a stranded group of strands of wire cable.
  • This device has four carrier parts, each with an endless chain of interconnected pressing tools, opposing pressing tools together encompassing the stranded material and thereby compacting it.
  • Rolls assigned to each pressing tool run on an endless running rail which is fastened to the corresponding carrier part.
  • Guide rings provided on each support part serve for lateral guidance of the pressing tools.
  • Each carrier part is pressure-loaded by adjustable springs, so that the pressing tools are pressed against the material with an adjustable pressure force.
  • US-A-3,225,798 relates to the manufacture of abrasive wire cables for stone saws.
  • a rotating pulling head for stranding a plurality of wires is connected to a fixed take-off device with two endless chains and fastened to them Collet halves with V-shaped grooves.
  • the rollers of the endless chains run in a predetermined section on adjustable pressure rails.
  • the object of the invention is to ensure and ensure the safety of the lifting of the collets following the distance specified by the pressure rail, regardless of the respective production speed, that the synchronism of the collets along the predetermined endless path is ensured.
  • collet halves are positively guided along the endless path outside of the distance determined by the pressure rail in addition to attachment to the drive chains.
  • This positive guidance applies to all collet halves in the same way, so that the reliability of each return spring assigned to each of the individual collet halves is eliminated from the outset.
  • the positive guidance ensures synchronism of the collets, which is not adversely affected by higher rotational speeds of the rotor.
  • the positive guidance consists of a profile rail in which a support roller engages is particularly advantageous. A migration of this support roller along the positive guidance is impossible; the is released Support roller only within the distance determined by the pressure rail, ie while the collets are clamping or taking effect.
  • the collet halves each consist of an outer carriage part and an inner slide part that is movable relative to this and the support rollers act non-positively on the respective slide part.
  • the support roller leaves the positive guide, the pressure rail and pressure roller become effective, so that the slide part of each collet half, including the associated support roller, is moved by the pressure roller, which is pressure-loaded by the pressure rail, in the direction of the stranded material and, after reaching around the material, the transport along the predetermined route can be performed.
  • the pressure rail takes effect after the support roller is released from the profile rail and before it is re-engaged.
  • extension is dimensioned such that the carriage part is guided over its length by rollers rolling on the running rail until the pressure roller becomes effective. In this way, tilting or tilting of the collet half is prevented from the outset, especially in the transition area between positive guidance and the collet becoming effective, which is sensitive to faults.
  • four rollers arranged symmetrically to the running rail are attached to guide the carriage part.
  • collet halves are attached to at least two chain links of the respective drive chain.
  • a particularly advantageous solution is obtained if, for reasons of symmetry, three links of the drive chain are used for mounting.
  • it is advantageous if, for fastening the collet halves, there are additional outer plates which are fastened to the respective drive chain and which also serve for lateral stabilization of the collet halves suspended on the drive chains.
  • each collet half is assigned a pressure roller, which acts on the slide part of the respective collet half under pressure from the pressure rail.
  • FIG. 1 shows a device 1 for stranding strand-like material as part of an entire system.
  • This consists essentially of a rotor 4 rotatably mounted within blocks 2 and 3.
  • This rotor 4 is driven by a motor 5 with alternating direction of rotation, a drive at different speeds to achieve the stranding effect is also possible.
  • the halves of the collet chucking the good 15 are denoted by 6.
  • the collet halves 6 are driven by drive chains 7, to which they are also attached.
  • the collet halves 6, as shown at point 9 are brought together to form a collet 14 comprising the material 15.
  • the collet halves 6 move in the direction of the arrow simultaneously with the rotation of the rotor 4 in the circumferential direction.
  • the material to be stranded for example wires 10 of an electrical power cable, are drawn off from supplies not shown and fed to a stranding point 12 via so-called roller guide devices 11.
  • a subsequent tape winder 13 strapping is applied to the stranded bundle before it runs into the rotating device 1.
  • the stranded material 15 is guided in the stretched state and can then be wound onto supply spools, not shown.
  • the collet halves 6 are next to the attachment to the Drive chains 7 additionally guided through a positive guide, as shown in FIG. 2. It shows a positive guide for the collet halves 6 in the form of a U-shaped profile rail 16 adapted to the drive chain shape. This profile rail 16 ends in the region of a pressure rail 17 by means of which a pressure roller 18 assigned to each collet half 6 is moved in the direction of the arrow.
  • the pressure roller 18 guided along the pressure rail 17 is relieved again at the end of the pressure rail 17 by the shape thereof, the profile rail 16 takes up the collet half 6 again.
  • a running rail 19 is arranged below the pressure rail 17. It takes over the leadership in pairs opposite guide rollers 20 and 21 which are arranged on an outer carriage part 25 of each collet half 6 and which roll to ensure tilt-free synchronism when merging the pair of collet halves 6 on the running rail 19. In order to make the inlet and outlet of each collet half 6 uniform and tilt-free, this running rail 19 is extended beyond the length of the pressure rail 17.
  • the extension of the running rail 19 is selected such that at the beginning of the pressure exertion when the pressure roller 18 strikes the pressure rail 17, as shown, each collet half 6 is already securely supported on the running rail 19 via both pairs of guide rollers 20 and 21. This results in a smooth transition from the forced guidance to the pressure-sensitive guidance and vice versa, from the pressure-sensitive guidance back to the positive guidance.
  • the positive guidance can be realized by a profile rail 16 with a U-shaped cross section, as shown in FIG. 3.
  • a support roller 22 protrudes into the profile rail 16, which on a frictional connection with a slide part 24 Collet half 6 connected carrier 23 is reached.
  • the profile rail 16 is shown in dashed lines in FIG. 3, ie the profile rail is not effective at the moment because the pressure roller 18 is under the influence of the pressure rail 17, which means that the slide part 24 is pressed against the stranded material 15.
  • a second collet half 6 then overlaps the material 15 from the other side, so that the frictional connection between the material 15 and the stranding device 1 is established.
  • FIG. 3 also illustrates the connection of the outer carriage part 25 to the drive chain 7, an outer link 26 being used for vibration-proof and tilt-free fastening, which is advantageously fastened to three chain links by means of protruding bolts 27.
  • a bolt connection 28 is used to connect the outer plate 26 to the outer carriage part 25.
  • FIG. 4 shows a side view of a collet half constructed in accordance with the invention.
  • the pairs of rollers 20 and 21 are fastened to the outer carriage part 25 symmetrically to one another and on both sides of the running rail, not shown.
  • the outer plates 26 arranged on both sides of the respective drive chain are used, which are non-positively connected to the drive chain by means of continuous chain bolts 27 and to the outer carriage part by means of fastening bolts 28.
  • the non-positively connected to the slide part 24 carrier 23 carries at its upper end the support roller 22 which engages in the operating state in the profile rail serving as a positive guide.
