  • the rotation of the winding head takes place by means of a belt drive which is guided over the circumferential side of the winding head.
  • Such a mounting head is preferably used in a system for automated cable harness production, as described in particular in WO 2018/189102 A1, especially in a fixing station or distribution station of such a system, as emerged, for example, from WO 2018/189104 A1, and where a banding is to be attached around a bundle of cables.
  • the invention is based on the object of enabling a reliable, automated, in particular fully automatic wrapping of a line strand, especially a bundle of lines.

  • the winding head itself also has a ring segment with a central winding space.
  • the ring segment has a lateral insertion opening for the lateral (transverse to the transverse direction) insertion of the cable strand into the winding space.
  • the ring segment also has a circumferential side and is rotatable about the axis of rotation. Furthermore, the end winding has a plurality of pressing elements which can be displaced in the radial direction against the line strand so that they are pressed against it. These pressing elements are attached to the ring segment.

  • no two separate guide devices are required, namely the guide elements (rollers) arranged at the entrance of the insertion opening and the swivel jaws pivoting into the center of the winding space. Rather, all three guide rollers are located in the central area of the winding space and exert a centering force on the bundle of cables so that it is reliably held in a central position during the winding process.

  • This front Winkelbe rich is, for example, at least twice as large as the rear Winkelbe rich. For example, it is between 60 ° and 100 °.
  • this forms a continuous guide structure that begins at the insertion opening and tapers in an initial state.
  • the wire harness is automatically guided in the direction of the center when the wire harness is inserted into the winding space. Due to the resilient bearing tion of the rollers, an adaptation to different diameters of the cable loom is also given.

Overall, the three rollers span a kind of triangle in a plane perpendicular to the transverse direction and, when the cable loom is inserted, rest against the sem over a circumferential range of preferably at least 180 ° or in a range of 180 ° (e.g. 170 ° to 190 °) .

Especially with the preferred use of a toothed belt drive, a reliable, in particular offset-free engagement of the individual teeth between the belt and the Ringseg element is guaranteed. Because of the insertion opening and thus the non-circular configuration, an offset occurs between the teeth of the belt and those of the ring segment when the winding head rotates, which leads to a less than optimal engagement.
  • the angular range over which the respective section extends is smaller than an opening angle over which the insertion opening extends. This ensures that the adjacent section does not extend beyond the insertion opening, so that there is no risk of a mismatch in which the teeth do not interlock reliably.

  • tangential contact of the drive element is provided in order to rule out an offset as far as possible.
  • the adjacent section therefore runs at least approximately along a tangential line. This is achieved with the interventions over only a small angle range of, for example, up to 20 ° or up to 30 °. In this case, preferably only a few teeth, for example 3 to 8 teeth of the toothed belt, mesh with corresponding teeth of the ring segment.

This ensures a real cutting movement with successive severing of the tape by the cutting element.
  • the winding module itself is also fastened to a guide unit of the assembly head and can be moved in the longitudinal direction in order to perform an infeed movement. This makes it possible for the winding module, especially the winding head, to be able to be advanced in the longitudinal direction of the line strand.

  • the clip 54 is positioned by means of the clip module 70 at a desired position (angular position) on the circumferential side of the cable loom 12 and in held this position.
  • the clip module 70 has for this purpose a correspondingly formed, very narrow gripper 74. Its width in the transverse direction 6 is, for example, only in the range between 10 and 30 mm.
  • the winding modules 2 are arranged directly next to this very narrow clip module 70.
  • the two winding heads 10 are advanced in the longitudinal direction 4, so that they are guided over the line strand 12 and this rests in the respective winding space 28. Banding then takes place. By means of the banding, the two fastening legs of the clip 52 are wrapped together with the cable loom 12 and the clip 52 is thus attached to the cable loom 12. Then the gripper 74 releases the (now fixed) clip 52 and the clip module 70 and the winding modules 2 are returned to the starting position against the longitudinal direction 4. A new cycle begins.
