Claims preview

1 . A coating booth for coating vehicle rims or other rotationally symmetric workpieces with coating material, wherein the coating booth comprises: a coating chamber having a booth floor, two oppositely positioned side walls, each having a workpiece passageway, two side walls oppositely positioned and adjoining the side walls with the workpiece passageways and a booth roof positioned opposite from the booth floor; a conveyor device for transporting the workpieces to be coated through the coating chamber, wherein the conveyor device is arranged beneath the booth floor and has a workpiece carrier which extends into the coating chamber of the coating booth through a conveyance slot in the booth floor; and an applicator system for spraying coating material within the coating booth as needed, wherein the applicator system comprises a first gun system for spraying coating material as needed onto a first area of the workpieces to be coated, a second gun system for spraying coating material as needed onto a second area of the workpieces to be coated, and a third gun system for spraying coating material as needed onto a third area of the workpieces to be coated, wherein the first gun system is assigned a first axis system for the positioning and/or aligning of the first gun system relative to the workpieces to be coated during a coating procedure, wherein the second gun system is assigned a second axis system for the positioning and/or aligning of the second gun system relative to the workpieces to be coated during a coating procedure, and wherein the third gun system is assigned a third axis system for the positioning and/or aligning of the third gun system relative to the workpieces to be coated during a coating procedure, wherein the first, second and third axis system are configured such that only the first gun system moves asynchronously to the traveling conveyor device whereas the second and third gun system move synchronously with the conveyor movement. 2 . The coating booth according to claim 1 , wherein the first gun system is designed to spray coating material as needed onto a visible area of the workpieces to be coated, wherein the second gun system is designed to spray coating material as needed onto a side region of the workpieces to be coated adjacent to the visible area, and wherein the third gun system is designed to spray coating material as needed onto a rear area of the workpieces to be coated opposite from the visible area. 3 . The coating booth according to claim 1 , wherein the first, second and third axis system are each designed as a system which travels along with the workpieces to be coated as the workpieces to be coated are transported through the coating chamber, wherein each axis system is movable relative to the coating chamber along the side walls adjoining the side walls with the workpiece passageways, wherein the axis systems are designed so as to move synchronously with a conveying speed of the conveying device.
