- the bottom flaps 2, 4 are rotated so far that their bottom can be blown off with compressed air.
- FIG. 2 is identical to that of FIG. 1, except that the outer bottom flaps 2 and 4, when adjusted to a minimum width of the floor longitudinal gaps 14, 16 adjacent thereto, are located higher than the surface 54 of FIG walkable bottom portion 18, wherein at least the lower sides 60 of the bottom flaps 2, 4 are arranged at its inner end higher than the surface 54 of the walkable bottom part 18, so that these wing bottoms 60 directed away from the compressed air 52 powder into the suction channels 26 and 28, respectively.
- Fig. 2 shows the bottom flaps 2 and 4 in solid lines in a horizontal orientation during the spray coating operation, and in dashed lines in an inclined position for cleaning the powder spray coating booth.
- dashed line in Fig. 2 drawn inclined position of the bottom flaps 2 and 4, an operator can see 26 and 28 in the lower corners of the suction channels and observe whether the suction ducts are cleaned clean.
- the bottom flaps 2 and 4 rotatable by 180 °, so that their Bottoms are turned up and then can also be blown off with compressed air for cleaning before a color change (powder change).
- the Pulversprühbe Anlagenbine 62 shown in Figs. 3, 4 and 5 is formed in its lower portion corresponding to FIGS. 1 and 2 or provided with a substructure according to FIGS. 1 or 2.
- Coating objects 64 are transportable longitudinally from the overhead conveyor 66 in the direction of travel 68, through the powder spray coating booth 62, and sprayed therein by powder guns 70 through automatic spray guns. Except for
- Spray coating booth may be located at their inputs and outputs 72 and 74, respectively, a freehand spray coating station 76 and 78, respectively.
- the bottom flaps 2 and 4 of the spray coating booth 62 are rotatable by a drive 80 in various rotational positions about an axis of rotation 10 and 12 running in the cabin longitudinal direction.
- the drive 80 may be an electric or pneumatic motor or hydraulic motor, preferably a cylinder with a plunger 82 that can be moved back and forth to rotate the respective bottom flap 2 and / or 4 in either direction.
- the bottom flaps 2 and 4 may also be provided on their upper side with compressed air outlets 50 for blowing compressed air into one or the other adjacent Bodenlijngspalte 14, 16, 20 and 22. Usually, however, compressed air outlets 50 on the accessible floor part 18 for cleaning also the surfaces of Bottom flaps 2 and 4.
- the compressed air can be supplied to the compressed air outlets 50 of the B ⁇ denklappen 2 and 4 preferably by a compressed air path 84 which extends axially to the axis of rotation 10 and 12 in the respective bottom flap 2 and 4 inside and inside the bottom flap transverse to the axis of rotation to the top of this bottom flap ,
- a compressed air path 84 which extends axially to the axis of rotation 10 and 12 in the respective bottom flap 2 and 4 inside and inside the bottom flap transverse to the axis of rotation to the top of this bottom flap
- the powder spray coating booth is located in its lower region, which may be formed as a substructure of the cabin, at least one, preferably at both longitudinal ends of a suction opening 92, 94, 96, 98 in the cabin floor via one of the suction channels 26 and 28. These suction are preferably adjacent to the end faces of the outer bottom flaps 2, 4 lying opposite this formed, as Fig. 8 shows schematically.
