Definitions

  • the present disclosure relates to a device and a method for twisting individual lines, in particular for twisting individual lines in pairs to form a line bundle.
  • cable bundles are required that are obtained by twisting individual cables.
  • the individual cables are usually cut to a certain length before twisting, i.e. cut to length, and if necessary also assembled, i.e. provided with a contact part or the like.
  • the line pair consisting of the individual lines is clamped between a holding unit at one end of the line and a twisting unit at the other end of the line and twisted by rotating the twisting unit.
  • the resulting shortening of the line pair is compensated by a longitudinal displacement of the twisting unit.
  • a corresponding device is described, for example, in EP 1 032 095 A2 shown.
  • the individual lines are twisted, i.e. they twist around their own individual line axis.
  • the EP 0 917 746 A1 discloses a device which enables To twist pairs of cables without unduly twisting the individual cables.
  • the holding unit is replaced by untwisting units, which each individually grip the individual cables at one end of the cable (the trailing end).
  • a longitudinally movable guide device separates the two individual cables with a guide mandrel and moves in the direction of the untwisting units during the twisting process. This allows the lay length to be kept constant.
  • the EN 10 2017 109 791 A1 discloses a device with untwisting units that are aligned parallel to each other at the beginning of a twisting process and are pivoted inwards by a motor during the twisting process. The pivot angle is continuously increased by a control device during the twisting process.
  • Other relevant documents are: DE19631770A1 , DE102016109152B3 and WO2012/015057A2 .
  • the known device provides a guide mandrel that standardizes the individual cables and the lay length. Particularly with long cables, for example, which are longer than 5 meters, in particular longer than 7 meters and preferably in the range of 10 meters, the cables may have an undesirable tendency to oscillate during the twisting process, which can make the lays irregular, for example due to an uneven lay length.
  • a device for twisting individual cables around a twisting axis to form a cable bundle along an extension axis comprises individual twisting units, a twisting unit and a guide device.
  • the individual twisting units are spaced apart from one another. For example, the distance is variable.
  • the individual twisting units are configured to separately hold, for example grip, cable ends at one end of the individual cables.
  • Each individual twisting unit can be mounted so as to be rotatable about an associated pivot axis.
  • the twisting unit is configured to hold and twist cable ends at the other end of the individual cables.
  • a guide pin is attached to the guide device.
  • the guide pin is used to at least partially separate the individual cables during a twisting process that is carried out by the twisting unit, in a region in which there is a transition from an untwisted area of individual cables to a twisted area of a bundle of cables.
  • the guide pin has a thickening on one side, which is opposite its attachment to the guide device. The thickening has larger dimensions in a direction transverse to the direction of travel of the guide pin than in a large part of the guide pin.
  • the thickening is a limited area which, for example, occupies less than 25%, preferably less than 15% of the extension of the guide mandrel in the direction of travel.
  • the thickening can effectively reduce unwanted vibrations that can occur during the twisting process, particularly for longer cables in the range >5m, preferably >7m and especially around 10m in length. This results in a more even beat sequence and better quality of the twisted cable bundle.
  • the thickening is designed to limit an oscillating movement during the twisting process.
  • the guide pin has a substantially circular cross-section, at least in some areas.
  • the guide pin has a larger diameter in the area of the thickening than in the majority of the guide pin. This results in a particularly simple configuration.
  • the thickening is formed on the end of the guide pin opposite the attachment to the guide device.
  • the guide pin then ends with the thickening. This can further reduce undesirable effects of a guide pin that is too long.
  • the guide mandrel has a widening in the direction of attachment to the guide device, so that a guide area for the individual cables is formed between the widening and the thickening.
  • the guide area is preferably designed in such a way that the individual cables do not leave the guide area even in the event of a strong tendency to oscillate. This ensures that the individual cables are guided securely during the twisting process.
  • a method for twisting individual cables around a twisting axis to form a cable bundle along an extraction axis using the device described herein comprises separately holding line ends at one end of the individual lines by means of the individual rotating units, holding line ends at the other end of the individual lines by means of the twisting unit, rotating the twisting unit to perform a twisting process, and limiting a swinging movement during the twisting process by means of the thickening of the guide mandrel.

  • Fig.1 There is a first line end 15 of the single line 11 and a first line end 16 of the single line 12 on the same side.

  • the individual lines 11, 12 are twisted, which results in a projection plane, for example in the drawing plane of Fig.1 , points are formed at which the individual lines 11, 12 cross each other.
  • the cable bundle 10 runs along an extension axis A.
  • Twisted refers to a state in which the lines 11, 12 wrap around each other.

  • the individual twisting units 41, 42 ensure through their rotation that the individual cables do not twist in on themselves, ie around their respective cable axes v1, v2.
  • the guide device 35 moves at a controlled speed in the direction of the untwisting unit 40, whereby the controlled speed results from the rotational speed of the twisting unit 30 and the desired lay length a2.
  • the twisting unit 30 is also moved slightly towards the untwisting unit 40 in order to compensate for the shortening of the twisted cable bundle 10 caused by the twisting. This movement can be controlled by the tension force, for example.
  • the thickening 361 on the guide mandrel 360 reduces the vertical swinging of the cables 11, 12 and thus improves the quality of the twisting process.
  • Fig. 19 an intermediate position is shown which is taken after the start of the twisting process and before the completion of the twisting process.
  • Fig. 20 and Fig. 21 show a top view of the individual turning units 41, 42 shortly before the completion of the twisting process.
  • the guide pin 360 still has contact with the individual lines 11, 12.
  • the guide device 35 moves the guide pin 360 further so that it loses contact with the individual lines 11, 12, as in Fig. 21 shown.
  • the distance 45 between the individual twisting units 41, 42 was further reduced. The actual twisting process is complete. This is followed by a final twisting process in which the twisting unit 30 is again rotated in the twisting direction, with the first crossing point P1 being brought even closer to the conductor ends.
  • the twisting process and the subsequent The final twisting process is then completed and the twisted cable is released from the twisting unit 30 and the individual twisting units 41, 42 and placed, for example, in a cable tray 160 (see Fig.4 ) is dropped.
  • the twisting unit 30, which is no longer rotating can be moved further in the direction of the untwisting unit 40 in order to relax the twisted cable bundle. In this case, the angular position of the individual rotating units 41, 42 can be blocked by actuating the brake 53.
  • Fig. 22 shows the elements of the device 100 in a position in which the guide device 35 has continued its linear movement until the guide pin 360 has approximately reached the line ends.
  • a release cylinder (not shown) actuates the point 357, whereby the released spring force moves the guide pin 360 into the Fig. 23 shown position outside the extension axis A.
  • the guide device 35 can be moved to the starting position without the guide mandrel 360 interfering with this movement.
