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 pair of individual cables is clamped between a holding unit at one end of the cable and a twisting unit at the other end of the cable and twisted by rotating the twisting unit.
  • the resulting shortening of the pair of cables 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 that makes it possible 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.
  • the JP2010123294A discloses a twisting machine with rotating elements as a single rotating unit and as a twisting unit. The document does not disclose that the single rotating units, to which the ends of the individual wires are connected, can be rotated or moved relative to each other.
  • a device for twisting individual lines about a twisting axis to form a line bundle along an extension axis comprises individual twisting units, a twisting unit and a distance adjustment device.
  • the individual twisting units are spaced apart from one another at a variable distance.
  • the individual twisting units are configured to separately hold, for example grip, line ends at one end of the individual lines.
  • Each individual twisting unit is mounted so as to be rotatable about an associated pivot axis.
  • Each pivot axis runs essentially perpendicular to the extension axis of the line bundle.
  • the twisting unit is configured to hold and twist line ends at the other end of the individual lines.
  • the distance adjustment device is configured to adjust the variable distance.
  • the adjustability of the variable distance means that impermissible bend angles of the individual cables at the untwisted cable end can be avoided, particularly at the end of the twisting process, which means that the untwisted area can be shortened further. This results in an improved yield of the twisted cable bundle.
  • the individual rotary units are mechanically coupled in such a way that the swivel angle between the individual rotary units is essentially always formed uniformly by the individual rotary units.
  • an adjustable, movable stop can be provided for a stop on at least A stop element provided for one of the individual rotary units can be provided, wherein the movable stop for limiting the swivel angle is specified in such a way that contact between elements of the individual rotary units, in particular between gripper tips of individual twist grippers of the individual rotary units, is avoided or prevented at a given distance between the individual rotary units.
  • the movable stop can also be moved in such a way that the individual rotary units assume a parallel position to one another.
  • a separate swivel drive is provided for each individual rotary unit.
  • the swivel drives are configured in such a way that together they enable a controlled specification of the swivel angle resulting between the individual rotary units.
  • the swivel angle is assumed to be appropriate and uniform, i.e. essentially the same on both sides, for the respective angle at which the individual cables run out of the individual twisting units in the direction of the twisting unit, so that the twisted cable bundle has an even lay.
  • the distance between the individual twisting units can be changed during the twisting process, which can make the lay even more even. It is also possible to further reduce the distance in order to carry out a final twisting process after the actual twisting process.
  • a control device for program-controlled and/or user-controlled specification of the variable distance.
  • the control device is configured, for example, to further reduce the variable distance of the individual turning units for carrying out the final twisting process.
  • a method for twisting individual wires about a twisting axis into a wire bundle along a pull-out axis, using the device described herein.
  • the method comprises separately holding wire ends at one end of the individual wires by means of the individual rotating units, holding wire ends at the other end of the individual wires by means of the twisting unit, rotating the twisting unit to perform a twisting process, and adjusting the variable distance by means of the distance adjusting device.
  • the method comprises, before holding the line ends separately, bringing the individual rotating units into a predetermined distance from one another, pivoting the individual rotating units into a parallel position, and taking over the line ends on the individual rotating units.
  • adjusting the variable distance during the twisting operation includes decreasing the variable distance. In embodiments, decreasing the variable distance is continued after completion of the twisting operation to perform a final twisting operation.

  • twisting process and the subsequent final twisting process are 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.
  • 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 performs its linear Movement has continued until the guide pin 360 has approximately reached the cable ends.
  • a release cylinder (not shown) actuates the point 357, whereby the released spring force causes the guide pin 360 to move 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.
