  • Some body parts can be effectively treated or painted in different orientations in space, so in different application situations, which for certain body parts differently executed systems are represented on the market, which are adapted to one or the other application position of the objects to be treated.
  • the bumpers can be mounted in a so-called installation position on the workpiece carrier. In this installation position, they are approximately aligned, as is the case with a bumper mounted on a vehicle, so that the front side of the bumper points largely in a horizontal direction perpendicular to the conveying direction. Bumpers in the installed position are arranged on the workpiece carrier in the vertical direction one above the other and usually such that their longitudinal extent between their two opposite side ends parallel to the conveying direction runs.
  • the bumpers can be mounted in a so-called sleeper position on the workpiece carrier, in which its front side is oriented upwards.
  • the bumpers are usually rotated relative to the mounting position about a vertical axis by 90 ° and extend perpendicular to the conveying direction. Bumpers in the sleeper position are usually arranged on the workpiece carrier in a horizontal plane one behind the other.

  • bumpers can often only be painted in one of the two application layers.
  • bumpers, or objects to be treated in general have to assume a position on a workpiece carrier during treatment phases before painting, which does not correspond to the application position required for the treatment unit.
  • the bumpers or other objects must be transferred before painting on another workpiece carrier and thereby brought into the required application position. This takes time and reduces accordingly the possible total turnover of the plant. Paint shops are off WO0183119 or GB2235421 known.
  • the objects are moved in a fixed conveying direction and the application robot or on a fixed rectilinear trajectory either only in parallel directions or only in directions perpendicular to each other.

  • the relative movement between the application robot and the objects to be treated can now be changed and given for bumpers, for example, depending on the application position in which they are conveyed through the treatment space.

  • the application robot is moved parallel to the conveying direction of the bumper.
  • the application robot can be moved perpendicular to the conveying direction of the bumper when the bumpers are conveyed through the treatment room in the sleeper position. This applies mutatis mutandis to other objects than bumpers.

  • objects in different orientations can be arranged on a single workpiece carrier. After, for example, bumpers have been painted in the installation position, the conveying direction can be changed relative to the application robot and bumpers can be painted in the sleeper position.
  • the robot trajectory has a curved course at least in regions.
  • a single existing rectilinear conveying path for the articles may suffice, since the desired and required change in the relative movement between the articles and the application robot can be achieved by a cornering of the application robot.

  • the application robot 44 and 46 must be parallel or perpendicular to the respective conveying direction 78th the bumper 14 can move. This is achieved by a corresponding assignment of the inlet and the outlet and the conveying path to be covered therebetween and additionally, if appropriate, by a point unit 68 which causes a rotation of the workpiece carrier 54, as described above.
  • the workpiece carrier 54 is preferably constructed so that it carries bumper 14 in the installed position only on the side facing the application robot when the workpiece carrier 54 and the application robot are moved parallel to each other.
  • a turntable or the like can also be provided in each case, so that the workpiece carrier 54 can ascend in an analogous manner from one rail track section to another.
  • the switch unit 68 can be dispensed with.
  • the first inlet 26 is connected via the conveying path 70 with the first outlet 30 and the second inlet 28 via the conveying path 74 with the second outlet 32, without a change in direction of the bumper 14 is possible while they are conveyed through the treatment space 16.
  • the bumpers 14 have to be conveyed via a specific inlet 26 or 28 into the treatment space 16.
  • the sidewalls can also be dispensed with and the air supply space 36 e.g. be supported with a frame structure.
  • the sidewalls can also be dispensed with and the air supply space 36 e.g. be supported with a frame structure.
