Definitions

  • the invention is in the field of stranding technology for electrical or optical cables and wires and is to be used in the structural design of a drive device with which the rotational movement of a rotating stranding head of an SZ stranding machine is periodically reversed between at least three movement states which persist in sections, i.e. in several stages becomes.
  • a known drive device which meets this requirement and has proven itself in practice provides for the actual stranding tool and its drive wheels to be arranged on a common rotatable hollow shaft through which the stranded material is guided, and the drive wheels on the hollow shaft to be rotatably supported, while each drive wheel is assigned a magnetic coupling arranged on the hollow shaft, the rotor of which is firmly connected to the hollow shaft (DE-AS 25 16 150). It is assumed that the twisting movement of the stranding head takes on two different states alternately. Several such stranding heads can be arranged working in parallel, the speed and the speed by an electronic device Rotational movement change of the stranding heads can be controlled ("Wire Journal", 1978, pages 74 to 79).
  • the invention has for its object to provide a drive device that ensures a quick reversal of the rotary movement of the stranding head with little design effort even if the rotary movement between at least three continuous movement states changed becomes.
  • the one or two magnetic couplings of the stranding head is assigned a drive shaft rotating at alternating at least two speeds, or that the one or both magnetic couplings of the stranding head have at least two clutches arranged on different drive shafts rotating at a constant speed assigned.
  • the new drive device is particularly suitable for SZ stranding machines for stranding communication cables, since as a rule several stranding groups are produced in parallel operations and consequently at least two stranding heads are arranged in parallel.
  • each drive shaft In order to be able to reverse the stranding heads as individually as possible, it is advisable to equip each drive shaft with at least two couplings, one of which is assigned to a group of stranding heads and the other to another group of stranding heads. This creates a good prerequisite for the fact that, for the purpose of electrical decoupling of the stranding groups which are later to be juxtaposed in the stranding assembly, one or more stranding heads can be connected to the respective drive shafts individually or in a phase-shifted manner to the other stranding heads.
  • FIGS. 1 to 7 Exemplary embodiments of the new drive device are shown in FIGS. 1 to 7.
  • 1 shows the basic structure of an SZ stranding machine
  • FIG. 2 shows the known structure of a stranding head with drive device
  • FIGS. 3, 4, 5 and 7 show diagrams of the course of speeds and twists
  • FIG. 6 shows a special assignment of drive shafts and stranding heads.
  • stranding elements 5 for example two or four cores, are stranded into a stranding group 6, for example a pair or a star quad.
  • the rotational movement of the twisting heads 3 and 4 is synchronously at intervals changed, correspond approximately to the transit time of a longitudinal section of the stranding the second stranding nipple 2 of the first stranding nipple 1, which have the distance 1 0th
  • the stranding heads 3 and 4 can be designed, for example, according to FIG. 2.
  • the actual stranding tool in this case consists of the three deflection rollers 31, 32 and 33, between which the stranded material runs in an undulating manner. These deflection rollers are mounted on a hollow shaft 34 through which the stranded material passes. Part of the drive device of the stranding head is also located on the hollow shaft 34. This first consists of the two drive wheels 35 and 36, which are attached to flanges 37 and 38 and are rotatably supported on the hollow shaft 34 via bearings 39 and 40.
  • Each drive wheel is assigned a magnetic clutch, which consists of the stator 41 or 42, the rotor 43 or 44 and the armature disk 45 or 46.
  • the stators 41 'and 42 in which the windings of the magnetic coupling are arranged, are fastened on a common support body 47, into which a retaining pin 48 is screwed. This retaining pin is supported in a manner not shown on the housing of the stranding head.
  • the stators 41 and 42 are supported by bearings 49 on the support body 50, which is connected in the same way as the adjacent rotors 43 and 44 via a feather key 51 to the hollow shaft 34.
  • the armature disks 45 and 46 of the magnetic couplings are connected to diaphragm springs 52 and 53, which in turn are fastened to the flanges 37 and 38 of the drive wheels 35 and 36 by means of the screws 54.
  • the drive wheels 35 and 36 Run to the operation of the twisting head, the drive wheels 35 and 36, die.
  • Understand toothed belt 9 and 1 0 coupled with drive shafts, not shown, with alternating intervals in speed and / or direction of rotation.
  • the hollow shaft 34 is driven via the magnetic couplings with the required speed and / or direction of rotation.
  • FIG. 3 shows a specific speed program for a stranding head 3, six speed stages with four different movement states of different directions of rotation being provided within one stranding period.
  • the stranding head should successively assume the speeds - n 2 , - n 1 , + n 1 , + n 2 , + n 1 , - n 1 , - n 2 etc.
  • Each speed is kept as long ten until a longitudinal section of the stranded material has passed the length l o between the stranding nipples 1 and 2.
  • This speed program results in SZ twisting of the stranded material, as shown in FIG. 4.
  • the distance between the reversal points of the twist direction is therefore approximately three times as large as the distance between the stranding nipples 1 and 2 from one another.
  • a stranding head 3 according to a speed program according to FIG. 3 can be achieved with the aid of two drive shafts, which according to FIG. 5 have a trapezoidal speed curve with the speeds - n 1 and + n 2 b between - n 2 and + n 1 .
  • the stranding head is coupled to the drive shafts via corresponding couplings for time segments A and B, as shown in FIG. 5 by the strongly drawn line segments.
  • the embodiment according to FIG. 6 shows ten SZ stranding heads 3 arranged in parallel for the production of stranding groups 6, on the hollow shafts 34 of which two magnetic couplings 7 and 8 are arranged.
  • the stranding heads are assigned four drive shafts 13, 14, 15 and 16, which rotate at constant speeds + n 2e + n 1 , - n 1 and - n 2 .
  • Each drive shaft is equipped with two clutches 17 and 18 or 19 and 20 or 21 and 22 or 23 and 24.
  • the stranding heads 3 are divided into two groups, each group being assigned a clutch of a drive shaft.
  • the couplings are connected via the drive belts 9, 10, 11 and 12 to the two groups of stranding heads, wherein Two clutches of two different drive shafts are assigned to one magnetic coupling.
  • a speed program can be designed for the drive wheels of the magnetic clutches 7 and 8 of the drive device according to FIG. 6, as shown in FIG. 7. Accordingly, the two drive wheels of all stranding heads of one stranding head group and the two drive wheels of all stranding heads of the other stranding head group rotate at speeds, the course of which is indicated by n 9 to n 12 according to the assigned drive belts 9, 10, 11 and 12. The reversal of the speeds of the individual drive wheels is offset from one another by the value t o / 2.
  • drive devices with three or five different movement states can also be realized, the speeds of the drive wheels of the magnetic clutches being able to be assigned to one another within wide limits.
