Definitions

  • the invention is in the field of stranding technology for electrical cables and wires and deals with the structural design of a stranding machine with a view to ensuring that the lay length is as uniform as possible in the stranded material, in particular in the area of the reversal points of the twist direction.
  • the quality of the SZ stranding essentially depends on the size of the distances of the those fixed points between which the stranding processes take place and the changeover times for changing the rotational movement of the rotating parts.
  • Short reversing times for SZ stranding of stranding elements can also be achieved if the stranding is not carried out with the help of concentrated or non-concentrated length memories, in which the resulting twisting of the stranded material results from the superposition of a first and at least a second twist, but with With the help of an oscillating stranding disk, which may be preceded by a compensating section (DE-OS 24 54 777).
  • the subsequent rope disk can automatically compensate for different lay lengths, which are caused by changing the direction of rotation of the stranding device to zero braked and then accelerated again to maximum speed (DE-OS 25 10 643, DE-AS 16 65 552, DE-OS 22 02 643, DE-OS 24 12 514).
  • the invention is based on a device for SZ stranding of stranding elements of electrical cables and wires to an SZ stranding unit, this device comprising one or more twisting devices arranged between a first and a last stranding point, rotating with a step-wise changing speed or direction of rotation, and one between the first and the last stranding point arranged, separated from the twisting device or integrated into this storage device for the stranding elements stranded at least a first time.
  • the invention has for its object to design such a device so that even if the storage device has a very large storage capacity of more than 50 m or more than 200 twist strands, a high quality of SZ stranding, ie short reversal points of the twist direction and uniform lay length also in the area of the reversal points is guaranteed.
  • the invention is based on the basic idea of separating the SZ stranding process of a stranding stage into a first stranding process of high stranding performance but lower stranding quality and a second stranding process of low stranding performance but high stranding quality.
  • a rope cable with one or two associated stranding nipples which can be driven by the SZ stranded stranding elements and is driven by an alternating direction of rotation immediately behind or before the last stranding point;
  • the free distance of the rope cable to the last stranding point or to the last part of the twisting device which non-positively grips and twists the outside of the twisting device is at least five times the resulting SZ lay length of the stranded material;
  • the speed of the rope pulley is equal to the difference between two successive speed levels of the rotating twist device and the direction of rotation of the rope rope can be changed in the same rhythm as the rotational movement of the twist device or with the same rhythm as the change from a speed reduction to a speed increase of the twist device or vice versa .
  • the actual stranding device which consists of the twisting devices and the storage device, is considered to be the pre-stranding device and the one with free one Spacing the rope rope referred to as re-stranding device.
  • the pre-stranding device then contains the main SZ store, the size of which is determined by the desired twist change distance in the stranded material.
  • This pre-stranding device can be constructed in a relatively simple manner with drives of moderate performance, with relatively long uns stranded sections at the swirl change points.
  • a single rope pulley alternately driven on the right and left, ensures precise formation of the swirl change points and constant lay lengths in the S and Z sections.
  • the rope cable is arranged at a free distance from the last stranding point or to the last part of the twisting device which non-positively grips and twists the stranding elements from the outside, the rope cable is preceded by an elongated storage device which at times has to absorb as much stranding strikes as is additionally generated by the stranding device should.
  • stranding brackets that fly around a buffer are used as the pre-stranding device, it is advisable to arrange the stranding device at the exit of the second stranding bracket and preferably to integrate it into this stranding bracket.
  • the rotational movement of the rope of the re-stranding device can be changed synchronously with the rotational movement of the stranding brackets.
  • the compensating distance upstream of the rope cable must be taken into account in the storage capacity of the entire stranding device.
  • the re-stranding device provided in the context of the invention can be used particularly advantageously if it is used in combination with a pre-stranding device as described in DE-ANM P 29 00 729.2 and in which a stretched storage unit in several parallel sections of storage is divided, which are interconnected via 180 ° deflection devices.
  • a stretched storage unit in several parallel sections of storage is divided, which are interconnected via 180 ° deflection devices.
  • SZ stranding device is arranged at the beginning and at the end of each storage section a rotating stranding head.
  • the post-stranding device can be integrated into such a pre-stranding device in such a way that the rope rope is integrated in the last stranding head, ie in the rotating stranding head arranged at the end of the last storage section.
  • the last partial storage section also acts as a compensation section for the rope cable.
  • FIGS. 1 to 5 Exemplary embodiments of an SZ stranding device designed according to the invention are shown in FIGS. 1 to 5.
  • FIG. 2 shows the re-stranding device equipped with a rope rope
  • FIG. 3 shows an SZ stranding device with a fixed accumulator and rotating stranding brackets as well as an integrated re-stranding device.
  • FIGS. 4 and 5 show an SZ stranding device designed as a folded linear memory with a downstream or integrated subsequent stranding device.
  • FIG. 1 shows a schematic representation of the SZ stranding of stranding elements 1 to form a stranding unit 5.
  • the stranding elements are first stranded by means of the main or pre-stranding device 2 to form strand 4.
  • the re-stranding or correction stranding device 3 which alone has the task of eliminating errors in the desired geometry of the stranding assembly 4 in the S and Z sections and at the swirl change points in between.
  • the SZ stranding device 2 is thus to be regarded as a pre-stranding device with which, for example, 99% of the necessary S and Z stranding strands are generated with moderate accuracy requirements.
  • the stranding device 3 works as a subsequent stranding device and generates the remaining percent of stranding strikes in the vicinity of the swirl change points and ensures a uniform distribution of the stranding strands.
  • the illustrated stranding principle can be easily realized in particular if the stranding elements 1 to be stranded are not plastically deformed, or only negligibly little, during the stranding process, as can be assumed in particular in the case of flexible electrical lines.
  • Fig. 2 shows the structural design of the re-stranding device 3.
  • This consists of the rope rope 7 rotating with changing direction of rotation and constant speed, which is assigned a stranding nipple 6 (rope rope nipple) on one side and the stranding nipple 8 on the other side.
  • the compensation section a is arranged in front of the stranding nipple 6, on which the twists exerted backwards by the rope rope 7 can be distributed.
  • This compensation section a should be able to accommodate at least as many lay lengths as are additionally generated by the roping device.
  • the direction of rotation of the rope rope 7 is always changed when the center of a swirl change point passes through the rope rope.
  • Their speed is adapted to the desired lay length of the strand 4 leaving the pre-stranding device.
  • the individual stranding elements 1 are combined after passing the rope rope 7 in the stranding nipple 8 to form the final SZ stranding unit 5 and precisely receive their final lay length s, which is given by the pull-off speed of the stranding assembly and the speed of the rope rope.
  • the length of the swirl change points is determined solely by the reversing speed of the rope rope 7 and by the distance between the rope nipple 8 and the next fixed point 10, which is formed here, for example, by a take-off disk.
  • the length of the rear compensation section or storage section a depends on the number of twist strings that have to be generated subsequently with the correction device. This length would be at least 1.5 m for a final SZ lay length of 0.3 m, and at least 0.5 m for a final SZ lay length of 0.1 m.
  • each S or Z section would contain 5000 twist strings.
  • + 50 stranding strands may be lost due to the relatively long reversing times of the twisting device.
  • These twist strings are made up in the re-stranding device 3, for which purpose a storage path a of approximately 2 to 10 m in length is required. The exact length is determined experimentally and depends on the length of the lay that is allowed within the storage distance a.
  • the storage path a and the rope rope 7 also have the effect of compensating for stranding irregularities which arise, for example, in the pre-stranding or main stranding device under the influence of torsion-resistant deflections.
  • FIG. 3 An exemplary embodiment of a complete pre-twisting and re-twisting device is shown in FIG. 3.
  • the stranding of the stranding elements 1 is carried out with the aid of stranding brackets 20 and 21, which fly around a fixed buffer 19 with a large storage capacity in a known manner (see DE-PS 16 65 536).
  • the subsequent stranding device from the rope nipple 6, the rope rope 7 and the stranding nipple 8 and the compensation section a, arranged.
  • the compensation distance a corresponds to the distance of the last deflecting roller 22 within the stranding bracket 21 to the cable nipple 6.
  • the exemplary embodiment shown in FIG. 4 is an SZ stranding machine, in which the subsequent stranding device shown in FIG. 2 is combined with a main stranding device, as described in DE-ANM P 29 00 729.2, and in which one of stretched memory is subdivided into a plurality of partial storage sections arranged in parallel in the levels a to d, the individual partial storage sections being connected to one another in succession by deflection devices.
  • the folded linear accumulator thus formed essentially consists of stranding heads 11, 12, 15 and 16 arranged between the two stranding points 10 and 17 as well as the deflection devices 14 and the straight-line guides 13.
  • the stranding heads are arranged in the vertical planes A and B.
  • the re-stranding device which in turn consists of the rope nipple 6, the rope rope 7 and the stranding nipple 8 and the stranding point 9, is arranged at a distance a behind the last stranding point (take-off disc) 17. Immediately behind it is an extruder 19 with which a plastic jacket is applied to the stranding unit 5.
  • the subsequent stranding device consisting of the rope nipple 6, rope rope 7 and stranding nipple 8 is integrated into the main stranding device, the stranding head 12 shown in FIG. 4 being replaced by the subsequent stranding device.
