Definitions

  • the invention relates to a method and a device for processing a cable, wherein the cable is rotated about the cable longitudinal axis to reduce the existing twist in the cable.
  • Such a cable drum then contains cable lengths of up to several thousand meters and can weigh up to about 80 kilograms.
  • the desired conductor length is pulled upside down by means of grippers and / or belt or roller drives from the non-rotating cable drum.
  • twisting occurs in the cable depending on the inner and outer diameter of the cable drum, or on the momentary cable Extraction diameter.
  • a 360 ° rotation occurs at 1.25 meters extended length, assuming the constant swirl propagation through the straightening section and the cable feed device.
  • twist in the cable is always built up when each end of the cable is held in place by means of grippers.
  • the cable can not freely untwist around the cable longitudinal axis. If only one end of a cable is held by means of a gripper, the twist in cable longitudinal axis can not build up at all or the cable can rotate arbitrarily around the longitudinal axis during the feed to length.
  • the twist in the cable is especially noticeable negative if the cable ends are provided with contacts which are not equipped in housing chambers in a 1: 1 order.
  • it is easy to create nodes that can only be released manually ( Fig. 1 ).
  • Desirable but is a cable tie after Fig. 2 Even contactless cables of greater length, which are bundled removed from the machine, tend to spin. As a result, tangled cables in the cable tie, which in turn must be unbundled manually.
  • a cable with strands as an electrical conductor has a certain number of individual wires and insulation. Depending on the conductor cross-section, for example, in the electronics area, 7 or 19 individual copper wires are stranded with a certain impact. ( Fig. 3 ). Depending on the direction of impact, a distinction is made between left-hand strike (S-blow) or right-hand blow (Z-blow). ( Fig. 4, 5 ).
  • the strand After stranding, the strand is provided by means of an extruder with insulation, which can be very different in hardness and thickness as needed.
  • the invention aims to remedy this situation.
  • the invention as characterized in claim 1 solves the problem of avoiding the disadvantages of the known device and to provide a method and to provide a device which counteracts the swirling in a cable.
  • Fig. 1 shows a consisting of several cables 1 cable bundle 2 caused by cable twist, aufyerder loop 3.
  • contacts 4 are arranged, with chambers 5 of connector housings 6 are equipped with the contacts 4.
  • Each cable 1 has been held at both ends of the cable 1.1 during its assembly (cut to length, stripping, put on the grommet, contact, etc.), so that, as shown above, built-up swirl could not arise and then causing the aufyerde loop 3 Has.
  • Fig. 2 shows the cable tie 2 with entdrillten cables 1 and without looping loop 3.
  • the cables 1 are after the Cut longitudinally about its longitudinal axis have been mechanically untwisted and thus can no longer form a loop 3 forming.
  • FIG. 3 to FIG. 7 show a stripped cable 1 with stranded strands 7 as an electrical conductor and their stranding.
  • FIG. 3 to FIG. 5 show a cable 1 with 7 strands 7th Fig. 6 and Fig. 7 show a cable 1 with 19 strands 7.
  • the type of strike (left turn or right turn) is symbolized by an arrow P1.
  • Fig. 8 shows a method for determining the twist in the cable 1.
  • the simplest way to determine the twist for example, as shown in Fig. 8 .
  • the cable 1 is manually removed from the grippers, for example a transfer unit 16, without the cable 1 being able to unscrew or untwist into its initial position.
  • the two ends of the cable 1.1 are brought together, wherein the cable 1 independently by its spin a plurality of forming loops 3 forms.
  • the twist direction is strongly dependent on the direction of impact of the individual wires.
  • the number of loops 3 (in Fig. 8 the cable 1 with a length of two meters has three loops) is a measure of the untwisting.
  • Fig. 8 are for untwisting the cable 1 a total of three revolutions in a clockwise direction (seen on the cable ends 1.1) necessary.
  • Fig. 14 shown Entdrillinheit 15 with two rotary grippers 20 leads each gripper 20.1 for unraveling the Kabls 1 according to Fig. 8 1 . 5 Clockwise revolutions (seen on cable ends 1.1).
  • the cable 1 is as a whole three times (twice 1.5 turns) in a clockwise direction (seen on the cable ends 1.1) rotated about its own longitudinal axis.
  • Fig. 9 shows a cable processing device 10.
  • the cable 1 makes in the removal of a barrel 11 excerpt turns clockwise or counterclockwise.
  • Drum cover 12 prevent swinging over the edge of the drum.
  • the cable passes via cable changer through the straightening distance to the cable feed device 13.
  • the leading end of the cable is held by a gripper of a loop depositor 14.
  • a transfer unit 16 takes over the leading and trailing cable ends from the loop pile 14 and transfers them to a de-twisting unit 15.
  • a cut-to-length cable 1 is held by the de-twisting unit 15 at the leading and trailing ends, the cable 1 having a loop 3 which raises before the uncoiling operation.
  • the de-twisting unit 15 may be placed in place of a transfer unit. After the Entdrillvorgang takes over the Transfer unit 16, the leading and trailing cable end of the unthreading unit 15 and leads the cable ends to the processing units 17, which assemble the cable ends. (Stripping, putting on grommets, attaching contacts, etc.). After the processing units 17, a bundle unit 18 is provided which takes over the prefabricated cables 1 from the transfer unit 16, wherein the bundle unit 18 forms a cable bundle 2 with the cables 1. Instead of the bundle unit 18, for example, an assembly unit for equipping plug housings 6 may be provided. With the untwisted cables 1, the cable bundle 2 has neither loops nor knots being raised.
  • FIG. 10 to FIG. 13 show the lengthening and untwisting of a cable 1.
  • the leading end of the cable 1 is taken from the loop pile 14.
  • the loop pile 14 leads, as in Fig. 11 shown, at the beginning of the cable feed with the leading end of the cable from a 180 ° pivoting movement.
  • the transfer unit 16 takes over both cable ends 1.1 of the cable 1.
  • the cable 1 is separated from the barrel-side cable and transported to the de-twisting unit 15, which eliminates the cable twist and thus the loop which is being raised with rotational movements about the cable longitudinal axis. ( FIGS. 12 and 13 ).
  • Fig. 14 shows the Entdrillinheit 15 with two motor-driven rotary grippers 20 for both ends 1.1 of the cable 1.
  • a motor 21 drives by means of toothed belt 22 Pulleys 24 of the rotary gripper 20, wherein the number of revolutions is monitored by a sensor 23.
  • a sensor 23 On a pulley 24, for example, a detectable by the sensor 23 metal mark is arranged.
  • the gripper 20.1 in the in Fig. 14 shown position in which the cable 1 can be readily supplied or further transported.
  • the position of the gripper 20.1 can also be determined after initialization by means of the encoder signals of the motor encoder 23a.
  • the gripper 20.1 are rotated before and after the Entdrillvorgang in the position shown, wherein the cable 1 can be fed or transported without additional movements. After taking over the cable ends 1.1 by the transfer unit 16, the gripper 20.1 are opened and the cable can be transported linearly. Experiments have shown that for unraveling the cable 1, the number of determined revolutions around the cable longitudinal axis sufficient ⁇ 1 ⁇ 2 turn.
  • the grippers 20.1 are pneumatically closed and opened. (Double-acting pneumatic device per gripper 20). A single-acting pneumatic device is also possible, in which the grippers 20.1 are pneumatically closed and opened by spring force.
  • the de-twisting unit 15 may be provided with only one rotary gripper 20, wherein twice the time is necessary for unthreading and the second cable end has to be clamped during this time. (In the example of the Fig. 8 the gripper of the single rotary gripper must make three turns counterclockwise). The same applies to linear machines with opposite cable ends, accordingly, only one Entdrillinheit with a rotary gripper is necessary here.
