Definitions

  • the present invention relates to a strand bundling device, by means of which a bundling strip can be placed in a bay shape on and around a linear strand, whereby the strand, in particular a cable harness or a cable harness structure with several branching individual strands ("cable harness"), is bundled.
  • the invention relates to a system which has such a strand bundling device or more such strand bundling devices.
  • Bundling a strand and applying a bundling strip around the strand to keep the strand bundled is difficult to automate in the prior art.
  • the assembly of additional elements on the strand and the assembly of the strand, for example in a motor vehicle bodyshell, is also a challenge for automation technology.
  • the prior art uses a wrapping tape to bundle strands or cable harnesses.
  • the additional elements are currently also attached to the strand with this wrapping tape. These additional elements are used when assembling the strand in the vehicle in order to attach it to/in the vehicle bodyshell.
  • the invention proposes a strand bundling device which has a strand bundling unit (A) or more such strand bundling units.
  • the strand bundling device in particular its strand bundling unit, is set up (i.e. designed and arranged) to lay a bundling strip, in particular bundling adhesive strip, in a bay shape on and around a linear strand and thereby bundle the strand or to combine the strand into a fixed bundle.
  • a system for bundling the strand is proposed, the system having one or more such strand bundling devices.
  • a method for bundling a strand using such a strand bundling device and/or using such a system is disclosed.
  • the strand can have a main strand and one or more secondary strands branching off from it, with one or more further secondary strands branching off from the secondary strands, etc.
  • the strand is in particular a wiring harness for a motor vehicle.
  • the strand can be formed from a large number of individual strands arranged in parallel; Here, a cable that is formed from several individual cables is understood to mean a strand.
  • the strand bundling device By means of the strand bundling device, in particular by means of its strand bundling unit, the strand is arranged parallel to a width direction (y) of the strand bundling unit and is moved relative to the strand bundling unit only along a straight bundling direction arranged parallel to a longitudinal direction (x) of the strand bundling unit through a bundling region of the strand bundling unit.
  • the strand enters the strand bundling unit along the bundling direction - in particular in the bundling direction.
  • the strand bundled by means of the bundling strip also emerges from the strand bundling unit along the bundling direction.
  • the strand In order to be bundled by means of the bundling strip, the strand enters the strand bundling unit in or against the bundling direction, but in any case parallel to it, and exits the strand bundling unit in or against the bundling direction, but in any case parallel to it - a movement of the Strand along its longitudinal direction is completely omitted.
  • the strand is moved relative to the strand bundling unit, for example by keeping the strand stationary and moving the strand bundling device towards or away from the stationary strand. Furthermore, it is conceivable that the strand is moved relative to the strand bundling unit by the strand bundling device being stationary and the strand being moved towards or from the stationary strand bundling device. Furthermore, the strand and the strand bundling device can both be moved and thereby moved towards or away from one another.
  • the strand bundling unit has a carrier device, for example a carrier plate, and a bundling strip dispenser, which is designed to provide the bundling strip in the bundling area.
  • the strand bundling unit includes a feeder device arranged on the carrier device and at least partially or partially in the bundling area.
  • the application device engages in the bundling area and is set up to take over the bundling strip from the bundling strip dispenser and place it in a bay shape around and on the strand by moving the strand along the bundling direction relative to the application device and thereby through the bundling area.
  • the bundling strip is the bundling adhesive strip (for example sections of an adhesive tape provided on a roll, etc.)
  • the bundling strip is preferably applied in such a way that one adhesive side of the bundling adhesive strip faces the strand, so that the adhesive sides of the protruding flags face each other and are glued together while moving the strand relative to the strand bundling device as part of the bundling process, that is to say automatically.
  • the strand bundling device In order to arrange the strand bundling device and the strand independently of each other again after bundling the strand or after the bay-shaped application of the bundling strip around and on the strand, so that the strand bundling device and the strand can be moved freely in space completely independently of one another, the strand bundling device is moved and/or the strand along the longitudinal direction (v) of the strand is not required.
  • This is advantageous in that it makes it possible to have a strand which has end elements at both ends (foot side of the width direction and tip side of the width direction of the strand bundling device) which prevent the strand bundling device from being removed from the strand along its longitudinal extension direction (v).
  • these end elements are in particular electrical coupling elements, such as plugs, sockets, etc., and/or branching or branching points at which another strand branches off from the bundled strand. Therefore, when the strand bundling device is used as intended, in particular in the method for bundling the strand by means of the strand bundling device and/or the system having the strand bundling device, provision is made according to the invention for moving the strand to bundle it and for subsequent independent movement along the strand bundling device the width direction (y), i.e. along the longitudinal direction (v) of the strand is completely omitted.
  • the strand bundling device includes in particular a cutting unit for cutting off the bundling strip or bundling adhesive strip.

  • the entry lock element and the counter-holder element are decoupled from one another by moving the entry lock element into its decoupling position, in which a first force and/or positive connection that can be mediated between the carrier device and the counter-holder element by means of the entry lock element is open.
  • a first force and/or positive connection that can be mediated between the carrier device and the counter-holder element by means of the entry lock element is open.
  • the counter-holder element and the carrier device are releasably and non-destructively reversibly fastened to one another by means of the exit lock element by adjusting the exit lock element into its coupling position, in which the exit lock element provides a different, second force and/or positive connection between the carrier device and the counter-holder element.

  • the counter-holder element advantageously guides the strand along the bundling direction, so that undesirable deflection of the strand is particularly reliably prevented.
  • a bundling strip remains stuck to the counter-holder element for a subsequent bundling process, so that the strand is brought into contact with the bundling strip particularly reliably.

  • the respective lock element has a corresponding connecting element of the connecting device.
  • the respective lock element has, for example, a first bayonet connecting element, a first threaded connecting element, a first magnetic connecting element and/or a first hook connecting element.
  • the carrier device or the counter-holder element - depending on whether the lock element is attached or fixed to the carrier device or on the counter-holder element - has an associated, corresponding connecting element of the connecting device, which means that the carrier device or the counter-holder element has, for example, a second bayonet connecting element second threaded connecting element, a second magnetic connecting element and/or a second hook connecting element.
  • the corresponding one of the first connecting elements and the corresponding corresponding one of the second connecting elements correspond to one another to form the connecting device.
  • the strand bundling unit has a movement support device attached to the carrier device, which is designed to push and/or pull the strand into the bundling area along the bundling direction.
  • the movement support device can, for example, have a movement support lever pivotably mounted on the carrier device or on the counter-holder element (if present), which can be driven by means of a pivot actuator in order to push or pull the strand along the bundling direction into the bundling area by means of the driven pivoting of the movement support lever.
