Abstract

A multicolor powder center is disclosed for supplying at least one powder spraying device with different types of coating powder as required. The multicolor powder center has a first powder container for receiving a first type of coating powder, at least one second powder container for receiving a second type of coating powder, and at least one pump unit comprising at least one powder pump. The pressure side of the at least one powder pump is fluidically connected or can be fluidically connected to the powder inlet of a powder spraying device. The at least one pump unit and/or the powder container can be moved relative to each other such that the suction side of the at least one powder pump is fluidically connected or can be fluidically connected either to the interior of the first powder container or the interior of the at least one second powder container as required.

First claim

The invention claimed is:

1. A multicolor powder center for supplying at least one powder spraying device with different types of coating powder as required, wherein the multicolor powder center comprises the following:
a first powder container for accommodating a first type of coating powder;
at least one second powder container for accommodating a second type of coating powder; and
at least one pump unit having at least one powder pump comprising a dense phase powder pump or thin stream powder pump, a pressure side of which is fluidly connected or connectable to a powder inlet of a powder spraying device;
wherein the at least one pump unit and/or the first powder container and the at least one second powder container are movable relative to each other such that a suction side of the at least one powder pump is fluidly connected or connectable to either an interior of the first powder container or an interior of the at least one second powder container; and
wherein the at least one pump unit is allocated a first vertical guide unit for vertical moving of the at least one pump unit or parts thereof.

2. The multicolor powder center according to claim 1 ,
wherein a cleaning station is further provided for cleaning the at least one pump unit, and/or a line system leading from the at least one pump unit to at least one powder spraying device, and/or at least one powder spraying device including when changing from the first type of coating powder to the second type of coating powder.

3. The multicolor powder center according to claim 2 ,
wherein the at least one pump unit is movable relative to the cleaning station such that the at least one pump unit can be cleaned in or at the cleaning station flushed with cleaning compressed air; or
wherein the cleaning station is movable relative to the at least one pump unit such that the pump unit can be cleaned in or at the cleaning station and flushed with cleaning compressed air.

4. The multicolor powder center according to claim 2 ,
wherein the first powder container and the at least one second powder container and the cleaning station are linearly and adjacently arranged.

5. The multicolor powder center according to claim 2 ,
wherein the at least one pump unit and/or the cleaning station is allocated a drive for moving the at least one pump unit relative to the cleaning station such that the at least one pump unit can be cleaned in or at the cleaning station flushed with cleaning compressed air.

6. The multicolor powder center according to claim 1 ,
wherein the at least one pump unit is allocated a carriage or slide assembly, by means of which the at least one pump unit can be movably guided in a horizontal plane and above the first powder container and the at least one second powder container as well as relative thereto.

7. The multicolor powder center according to claim 1 ,
wherein the at least one pump unit comprises a docking unit via which the suction side of the at least one powder pump can be fluidly connected to the interior of one of the first powder container and the at least one second powder container.

8. The multicolor powder center according to claim 7 ,
wherein the docking unit is allocated a second vertical guide unit, by means of which the docking unit is vertically movable relative to the at least one powder pump of the at least one pump unit and the first powder container and the at least one second powder container.

9. The multicolor powder center according to claim 1 ,
wherein the first powder container and/or the at least one second powder container is allocated a linear drive, for moving the first powder container and/or the at least one second powder container relative to the at least one pump unit.

10. The multicolor powder center according to claim 1 ,
wherein the first powder container and/or the at least one second powder container are each able to be moved relative to the at least one pump unit independently of one another.

11. The multicolor powder center according to claim 1 ,
wherein at least one powder pump of the at least one pump unit is independently operable, and is arranged in the at least one pump unit such that in a state during which the at least one pump unit is coupled to the first powder container and/or the at least one second powder container or a cleaning station, the at least one powder pump is connected on the suction side to the interior of the first powder container and/or the at least one second powder container or the cleaning station.

12. The multicolor powder center according to claim 1 ,
wherein the at least one pump unit comprises a first and at least one second pump unit, each comprising at least one powder pump that comprises a dense phase powder pump, wherein the first and second pump units are movable relative to the first powder container and the at least one second powder container independently of one another such that:
the suction side of the at least one powder pump of the first pump unit and the suction side of the at least one powder pump of the at least one second pump unit are fluidly connected or connectable to either the interior of the first powder container or the interior of the at least one second powder container.

13. The multicolor powder center according to claim 12 ,
wherein the first and the at least one second pump unit are movable relative to each other and relative to the first powder container and the at least one second powder container in at least one horizontal direction; and/or
wherein the first and the at least one second powder container are movable relative to each other and relative to the first and the at least one second pump unit in at least one horizontal direction.

14. The multicolor powder center according to claim 1 ,
wherein the first and second powder containers are arranged arrayed together in a matrix, and wherein the at least one pump unit is movable in a first horizontal direction and in a second horizontal direction orthogonal to the first horizontal direction relative to the first powder container and the at least one second powder container such that the suction side of the at least one powder pump is fluidly connected or connectable to the interior of one powder container of the first powder container and the at least one second powder container.

15. The multicolor powder center according to claim 1 ,
wherein the first powder container and the at least one second powder container are arranged arrayed together in a matrix, and wherein the first powder container and the at least one second powder container are movable in a first horizontal direction and in a second horizontal direction orthogonal to the first horizontal direction relative to the at least one pump unit such that the suction side of the at least one powder pump is fluidly connected or connectable to the interior of one powder container of the first powder container and the at least one second powder container.

16. The multicolor powder center according to claim 1 ,
wherein the first powder container and the at least one second powder container are arranged arrayed together in a matrix, and wherein the first powder container and the at least one second powder container are movable in a first horizontal direction and the at least one pump unit is movable in a second horizontal direction orthogonal to the first horizontal direction such that the suction side of the at least one powder pump is fluidly connected or connectable to the interior of one powder container of the first powder container and the at least one second powder container.
