  • the base plate 27 also rotates about a vertical axis, i.e., the worm gear 17, the output shaft 18 and the sprayer 21 attached thereto. around the Z axis.
  • the electric motor 22 thus drives the base plate 27 via the shaft 23, the angular gear 24, the shaft 25, and the bevel gear pair 26 and thereby swivels the spraying devices 21 about the Z axis.
  • the side machine shown schematically in FIGS. 2-4 is thus provided with four stationary explosion-proof electric motors 1, 7, 12 and 22, by means of which the spraying devices 21 can be displaced in the Z direction and in the X direction and also about the Z axis and are pivotable about the Y axis.
  • the gears 10, 14 and 24 are fixed to the carriage 6 and follow its movements.
  • the transmission of the forces or moments from the electric motors to the spray heads takes place exclusively by mechanical means, whereby the use of movable hoses or cables can be avoided.
  • the Y direction is the direction of movement of the motor vehicle, i.e. the direction of the conveyor belt on which the motor vehicle is arranged during processing.
  • An electric motor 30, which drives an angular gear 31, is arranged stationary on a frame 28.
  • the latter has two output shafts, namely a connecting shaft 33 which drives a further angular gear 34 and a vertically running threaded spindle 32.
  • the angular gear 34 also has a vertically running threaded spindle 35 as an output shaft.
  • the two angular gears 31, 34 are fixed at a horizontal distance on the frame 28.
  • the two threaded spindles each engage in a threaded nut 36 and 37, which in turn are fixedly arranged on a frame 38 of the roof machine, in such a way that by rotating the threaded spindles 32 and 35, the frame 38 vertically, i.e. can be moved up and down in the Z direction.
  • the frame 38 is thus driven by the stationary electric motor 30 via the angular gear 31, 34 and the threaded spindles 32 and 35 in the direction of the Z axis.
  • An electric motor 39 is attached to the frame 38, to which a gear 40 (FIG. 6) is coupled, which drives two chain wheels 41.
  • a gear 40 (FIG. 6) is coupled, which drives two chain wheels 41.
  • two further sprockets 43 are rotatably mounted on the frame 38 and two chains 42 are guided over the sprockets 41 and 43, with which a carriage 44 is connected.
