Painting device
The invention relates to a painting system which comprises a painting device ( 121 ) in the painting chamber ( 103 ), said painting device comprising a casing ( 113 ) that surrounds the workpiece support ( 107 ) such that paint droplets that are not deposited onto the workpieces are dripped onto the casing to a large extent and can thus be reused.
1. Coating facility ( 101 ) comprising a painting chamber ( 103 ) that is placed in a painting device ( 105 ), wherein the painting device ( 105 ) comprises a painting robot ( 119 ) and a workpiece holder ( 107 ) holding at least one workpiece ( 111 ) wherein the painting device ( 105 ) comprises a movable casing ( 113 ) and the workpiece holder ( 107 ) comprises a frame ( 109 ) and a workpiece mount ( 111 ), wherein the casing ( 113 ) is placed during the painting process between the frame ( 109 ) and the workpiece mount ( 111 ), characterized in that
the casing ( 113 ) is configured to move in the painting chamber ( 103 ) at least in the vertical direction in such a manner that the casing ( 113 ) is placed in at least a first raised position and a second lower position, so that
while the casing ( 113 ) is placed in the first position the workpiece holder ( 107 ) is placed in the painting chamber ( 103 ), and
once the workpiece holder ( 107 ) has been placed in the painting chamber ( 103 ), the casing ( 113 ) is lowered from the first position and placed in the second position, so that the casing ( 113 ) is put over the essential components of the workpiece holder ( 107 ) and placed between the frame ( 109 ) and the workpiece mount ( 111 ) in such a manner that the casing ( 113 ) encloses the workpiece mount ( 111 ), and
the casing ( 113 ) is removed from the second position after the painting process in such a manner that the casing ( 113 ) releases the workpiece holder ( 107 ) and is moved back to the first position.
2. Coating facility according to claim 1 , characterized in that the painting device ( 105 ) includes a gas inlet arrangement ( 115 ) so that during the painting process, a gas flow flowing through the inside of the casing ( 113 ) is applied to the workpieces.
3. Coating facility according to claim 2 , characterized in that the casing ( 113 ) has a tapering, allowing the flow rate of the gas flow to be increased and the paint droplets generated through the painting process to be carried along.
4. Coating facility according to claim 1 , characterized in that the painting device ( 105 ) comprises a catch vessel ( 117 ) in such a way that the paint collecting on the casing ( 113 ) and dripping from the casing ( 113 ) runs into the catch vessel ( 117 ) and be fed to a recovery system.
5. Coating facility according to claim 2 , characterized in that in the coating facility, a supply of solvents is provided in such a way that a solvent is added to the gas introduced in the inside of the casing through the gas inlet arrangement that prevents the paint from drying on the walls of the casing and/or in the catch vessel.
6. Coating facility according to claim 1 , characterized in that the painting robot is connected to a paint nozzle with a movable arm.
7. Coating facility according to claim 6 , characterized in that the casing comprises a plurality of slits, wherein the paint nozzle is movable by the painting robot through at least one of the slits.
