Abstract

A multicolor powder center is provided for supplying at least one powder spraying device with different types of coating powder as required. The multicolor powder center has at least one powder container for receiving coating powder and at least one pump unit comprising at least one powder pump, in particular a dense flow pump or a diluted flow 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 pump unit is paired with a docking unit, via which the suction side of the at least one powder pump can be fluidically connected to the interior of the 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:
a first powder container for accommodating coating powder;
at least one second powder container for accommodating coating powder;
a first pump unit having at least one powder pump, including 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; and
at least one second pump unit having at least one powder pump, including a dense phase powder pump or a 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 first pump unit is allocated a first docking unit via which a suction side of the at least one powder pump of the first pump unit can be fluidly connected to an interior of the first powder container or the at least one second powder container,
wherein the at least one second pump unit is allocated a second docking unit via which a suction side of the at least one powder pump of the at least one second pump unit can be fluidly connected to an interior of the first powder container or the at least one second powder container,
wherein the first pump unit and the at least one second pump unit 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; and/or
the suction side of the at least one powder pump of the first pump unit is fluidly connected or connectable to the interior of the first powder container and the suction side of the at least one powder pump of the at least one second pump unit is fluidly connected or connectable to the interior of the at least one second powder container, respectively.

2. The multicolor powder center according to claim 1 ,
wherein the first pump unit 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 least one horizontal direction; and/or
wherein the first powder container and the at least one second powder container are movable relative to each other and relative to the first pump unit and the at least one second pump unit in at least one horizontal direction.

3. The multicolor powder center according to claim 1 ,
wherein the at least one second powder container comprises a plurality of powder containers arranged arrayed together in a matrix, and wherein the at least one second pump unit is movable in a first horizontal direction and in a second horizontal direction orthogonal to the first horizontal direction relative to the powder containers 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 plurality of powder containers.

4. The multicolor powder center according to claim 1 ,
wherein the at least one second powder container comprises a plurality of powder containers arranged arrayed together in a matrix, and wherein the plurality of powder containers are movable in a first horizontal direction and in a second horizontal direction orthogonal to the first horizontal direction relative to the first pump unit or the at least one second 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 plurality of powder containers.

5. The multicolor powder center according to claim 1 ,
wherein the at least one second powder container comprises a plurality of powder containers arranged arrayed together in a matrix, and wherein the plurality of powder containers are movable in a first horizontal direction and the first pump unit or the at least one second 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 plurality of powder containers.
