Definitions

  • the invention relates to an application device for applying a sealing profile on a body part serving to close a body opening, with a curling head for applying the sealing profile and gluing the sealing profile with the intermediary of an adhesive on a surface of the body component, wherein the curling head has a feed path through the sealing profile for advancing the sealing profile from a storage location to the surface of the body component.
  • Such sealing profiles are for example intended to produce a sealing connection between a body opening and the cover inserted in it.
  • a cover may be, for example, a door, a trunk lid or a sunroof element.
  • a vehicle door which, at the stage in which the sealing profile is applied to it, can also be referred to as a door assembly.
  • the sealing profile is conveyed by an endless roll by means of a conveyor and applied via a rolling head.
  • a feed path which regularly comprises a plurality of conveyor rollers and at least one pressure roller and which is responsible for the fact that the feed rate of the sealing profile is adapted to the speed at which the door assembly is moved along the application device.
  • the advance of the sealing profile onto the door assembly is regulated accordingly.
  • the door assembly itself is movably received in a movable mounting device, for example via an industrial robot, and is guided past the stationary rolling head, which in this case applies the sealing profile to the door assembly.
  • the door assembly may be held stationary and the other head may be moved along the door assembly.
  • a cutter of the roll head cuts through the weather strip to cut it off the endless roll.
  • the pressure roller that was last placed in the direction of feed is of the several conveyor rollers.
  • About the pressure roller takes place directly the transfer of the sealing profile to the door assembly in an application point, so that on the pressure roller a corresponding loading of the sealing profile on the surface of the door assembly takes place.
  • the cutting device is placed in front of the pressure roller, so that after the cutting profile has been cut to length via the cutting device, the sealing profile section still located between the cutting device and the application point of the pressure roller must be applied to the door assembly and only thereafter the joint area results, in which the two end portions of the sealing profile opposite one another largely gap-free.
  • the sealing profile to be applied next this means that it first has to be conveyed from the cutting device to the point of application along the feed path.
  • the control of the application device drives the conveyor rollers within the feed section for a certain period of time of a few to several seconds, so that the sealing profile is advanced to the point of application and then with the actual application on the Door assembly is started.
  • the length of time of this driving is essentially determined by the material properties of the sealing profile and empirical parameters which permit a statement as to how much slippage can be expected between the conveyor rollers and the sealing profile at a certain driving speed.
  • the variance of the initial position becomes a technical problem when more length of the sealing profile has been conveyed than required, ie the sealing end face has been placed beyond the point of application.
  • this case can lead to the handling robot moving the sealing profile laterally, that is to say in the Y direction, as the door assembly approaches the sealing profile or the application point.
  • the second end section is glued to the door assembly in the resulting abutting area with the correct Y coordinate, an offset between the two end sections in the Y direction results in this area. This, in turn, may cause the overlapping sealing end surfaces can not be sufficiently glued together and / or results in an insufficient seal in subsequent operation.
  • the application device regularly comprises a so-called shock detection sensor, the first End portion, or its sealing end face, the already applied-applied sealing profile can detect.
  • the person skilled in the art could consider DE 39 41 376 C2, which proposes an adjustable mechanical stop in an application head up to which the sealing profile is made from the actual application head and which forms the sealing profile into a curved one Contour forces, up to a defi ned position of the held end face.
  • a disadvantage here can be considered that the curved contour of the sealing profile after exiting the application head is more of an undefined contour whose curved course will be subjected to a large scatter. Proceeding from this, the object of the present invention is to provide an application device which is capable of ensuring, with very little scattering, advancement of the sealing profile within the application head up to the point of application.
  • an application device for applying a sealing profile on a body component serving to close a body opening, having a rolling head for applying the sealing profile and adhesively bonding the sealing profile.
  • an adhesive on a surface of the body component having a feed section passed through the sealing profile, for advancing the sealing profile from a storage location to the surface of the body component, and a contactless feed detection sensor system via which a predetermined feed position of the sealing element profile is detectable on the feed line.

  • the structural components of the advance detection sensor system can also be placed in places where they are not hindering, and with their non-contact sensors detect areas where a tactile sensor system would generally be a hindrance.
  • a non-contact advance detection sensor system also offers the possibility of a so-called pre-detection, so that the positioning accuracy of the sealing end face on the application point can be further increased. With the application device according to the invention, it is possible to reduce the variance of the initial position of the sealing profile to +/- 1 mm.
  • a magazine-mounted continuous roll may be designated by means of a storage location, from which the sealing profile is unrolled or conveyed continuously.

  • the use of an opto-electrical sensor can be adapted to different requirements and is available in various designs.
  • the use of an optoelectrical sensor as a light barrier or as a light sensor is favorable in view of the limited space available in and on the application head, since it only has to be ensured that the desired position of the application point lies in the region of the light path.
  • An advantageous embodiment of the invention provides that the Vorschuberkennungssensorik between a detection position in which the sealing profile is detectable on the feed path, and an inactive position in which the sealing profile on the feed section is not detectable detectable, is designed to be movable. In this way, it is finally advantageously possible despite the limited space in and on the application head, the Vorschuberken- ubenssensorik at the optimal location as close to the application point to place and at the same time to ensure that during the later application of the sealing profile it does not collide with the handling device which guides the door assembly.
