Definitions

  • the invention relates to a method for bundling and bandaging a plurality of objects, e.g. Several electrical lines by means of a band made of weldable material, in particular by means of a plastic band to a wire harness. It also relates to a device for carrying out the method. Such a method and a device used for its implementation according to the preamble of claim 9 are known from EP-A-0 399 599.
  • the tensile stress is maintained until the bundle loop is welded in the area of the band joint by a high-frequency welding device.
  • the welding takes place there against the counter pressure of two counter electrodes pivoted like pliers into a counter holding position on the inside of the belt loop.
  • the electrode which had previously fixed the band joint against the counter-holding elements is withdrawn and the endless belt projecting beyond the weld connection joint is cut off.
  • This method has the disadvantage that the outer layer of the endless belt facing the electrode in any case during the welding joint area remains exposed to tensile stress during welding. If this tension were eliminated beforehand, the bundling of the objects would loosen before or at the start of the welding process. Furthermore, this method and the device used for its implementation have the disadvantage that a separating end of the endless belt generally remains beyond the weld joint, which protrudes radially outward when the bundle is used further, for example when robotic installation of such a bundled wiring harness.
  • EP-A-0 248 295 shows a method and a device for carrying out the method for automatically strapping an object with the aid of a plastic band.
  • the tape is not first fixed outside the overlap area, but in the overlap area at the location of the subsequent weld joint, although the knife cuts the tape before welding, but is not arranged on the welding device.
  • the first fixation must therefore first be released so that the band areas to be welded to one another can immediately overlap.
  • a bundling effect of the sling decreases.
  • objects to be bundled push radially outwards against the sling. This radial force creates a tensile stress in the band area arranged on the welding device.
  • the invention is based on the object of creating such a method which avoids the disadvantages mentioned and in particular is able to create dense bundles with simple means, beyond the bandage of which no separating ends of the bandage band interfere. At the same time stable and permanent weld connection in the weld joint area. This object is achieved by the combination of features of claim 1.
  • the method according to the invention has the advantage that the layers of the endless belt that are welded together in the welding joint area are absolutely free of tension, without thereby endangering the tight bundling of the objects to be bandaged.
  • the bandage band is previously fixed on both sides of the weld, not directly against the objects to be bundled, but indirectly against a counterholder which lies between the weld joint area of the endless belt and the objects to be bundled. It also takes over the heat shielding of the welding point from the objects to be bundled and during the welding process also the function of the transmission means of the bundling tensile force in a bypass area to the welding point.
  • the counter-holder can also be designed as a part remaining in the bundle after the welding. This enables particularly dense bundling with high bundling tensile force.
  • This dense bundling makes it possible, for example, to include resilient spreading elements in the bundle in the bundle area, which at least later temporarily fix the bundle, for example the cable harness, to the installation object by simply cutting open the bundle band (Automobile body) enable.
  • the bundle band Automobile body
  • the shape of the counter holder is the subject of claims 10-14.
  • the type of interaction of the fixing slide with the counter-holder is the subject of claim 15.
  • the cross-holder acts as a shaping means with respect to the objects to be bundled due to a circular segment-like channel shape.
  • the counter-holder can also have a different cross-sectional shape adapted to the respective installation location. This makes it possible to give the bundle a cross-sectional contour that deviates from a circular cross-sectional shape.
  • the counter-holder according to the invention has the advantage of also forming the welding anvil opposite the surface of the welding sonotrode for the immediate welding process.
  • the procedure is essentially described with reference to FIG. 1, which is limited to the most essential functional parts of the device for performing the procedure:
  • the procedure is used for bundling and bandaging several objects, in the exemplary embodiment electrical cables 1, the longitudinal axes or longitudinal extension of which are perpendicular to the plane of the drawing in FIG 1 runs. These lines, which are shown at a large distance from one another in FIG. 1, are to be bundled into a tight bundle in the manner of a cable harness.
  • the bundling takes place by means of a band 2 made of thermoplastic plastic, which can be pushed into and out of the bundling area in a motor-controlled manner from the side 3 in the feed or pulling direction 4.
  • the endless belt 2 is guided by the motor of the bundling device with its free end 5 to form a band loop by more than 360 ° around the lines 1 to be bundled.
  • the free end 5 of the band 2 is in a covering position by the endless band part 6.
  • the type of loop formation is fundamentally known, namely described in detail in the US reference mentioned at the beginning.
  • the belt 2 is fixed in a fixed manner outside the overlap region 7, which is identical to the endless belt part 6, on its side facing away from the free end 5, specifically by the fixing slide 8, which in the direction of arrow 9 is essentially radial to the bundling region is movable.
  • the band is fixed by the fixing slide 8 against the counter-holder 10, on the outside of which the band part adjoining the free end 5 of the band 2 bears.
  • the method step marked with c) in claim 1 takes place.
  • the band loop in FIGS. 1 and 5 which still has the inside diameter of the band guide ring 11, is drawn in to bundle the lines 1 (Fig. 6) and after completion of the closing under an adjustable tension, how the retraction in the downward direction of the arrow 4 is effective.
  • the endless belt 2 is moved in the area between the two fixing positions marked by the fixing slide 8 and the fixing slide 12 by means of the sonotrode 14, guided from the outside against the counter-holder 10, of an ultrasonic welding device with the covered, bundle-side belt area 15 welded.
  • the sonotrode 14 is guided in the direction of the arrow 16 against the bundle or against the counter-holder 10.
  • the endless belt 2 which had previously been held under the set tensile stress, is cut off in such a way that the welding of the separating end 17 of the belt loop to the inside bundle-side band region 15 takes place completely.
  • the strip 2 is cut off by the separating knife 18 molded onto the lower edge of the sonotrode 14.
  • the separating end 17 is automatically retracted into the detection area of the sonotrode 14 on the basis of the inherent elasticity that it is complete is welded to the bundle-side band region 15 without a laterally projecting end.
  • the welding of the separating end 17 or the weld joint is carried out with two completely tension-free band areas.
  • the counter-holder 10 is pulled out of the bundling area perpendicular to the plane of the drawing 2, namely in the direction of the arrow 20 (FIG. 8).
  • the bundling process is now complete.
  • the bundle is finished.
  • the initial fixation of the band according to feature b) of claim 1 can be controlled by reaching the target position of the free end 5 according to FIG. 1 and FIG. 5 or by reaching a supplied band target length which can be set on a step feed drive.
  • the second fixation by means of the fixing slide 12 according to feature d) of claim 1 can be controlled by reaching a desired tensile force acting downward in the direction of arrow 4 when the webbing is pulled shut (claim feature c)).
  • the device for carrying out the method contains a motor-driven guide device 21 which pushes the endless belt 2 drawn off from a storage side 22 in the feed direction 4 to the loop-forming belt guide ring 11 and can also be switched according to the two direction arrows 4 in the downward direction 4 in FIGS. 1 and 5 .
  • the band guide ring 11 consists of two semicircular ring segments 23, 24, the lower 24 of which is stationary, while the upper ring segment 23 can be swiveled up in the direction of arrow 26 by the motor drive 25 to open the ring.
  • the lines 1 are inserted into the bundling area.
  • the upper ring segment 23 is pivotable about the pivot axis 27 for its pivotability.
  • the counterholder is effective as a unitary part against the fixing slides 8, 12 as well as against the sonotrode 14 of the welding device. It is a bundling aid device in the manner of a channel of any cross-sectional shape open with its concave side 28 towards the bundle, with a longitudinal direction parallel to the longitudinal axis of the bundle running perpendicular to the image planes educated.
  • the channel shape in particular the configuration of its concave side 28, can be designed as desired, in particular in adaptation to the conditions on the installation object for the bundle or for the cable harness. Therefore, the design of the counter-holder 10 or its channel shape has a not insignificant meaning for the variable shaping of the bandaging area of the bundle in certain areas.
  • the counter-holder 10 has the shape of approximately a circular arc segment with a bending radius adapted to the bundle diameter. In cross-section it describes an arc of between approximately 90 ° and 130 °.

  • the fixing device formed by the pivoting part 29 for the initial fixing is pivotably mounted about an end distal to its bundle about an axis 41 parallel to the bundle longitudinal axis. This pivoting is carried out by the pivoting part 29 flanking pressure slide 42, 43, namely between the fixing point for the first fixation (Fig. 5, 6 and 7) and the starting position for the loop formation (Fig. 2, 4).
  • the separating knife 18 between the mouth 31 of the fixing device provided with the band channel 30 and the sonotrode 14 is integrally formed on the lower edge of the sonotrode 14 and projects beyond its welding surface in such a way that the separating cut takes place before the welding is carried out.
