Abstract
Exemplary coating devices and exemplary coating methods for coating components with a coating agent, e.g., for painting motor vehicle body components with a paint, are disclosed. An exemplary coating device comprises an application device that applies the coating agent. The application device may include a paint head that discharges the coating agent out of at least one coating agent nozzle.
Claims10
Coating device for coating components with a coating agent, comprising:
- an application device that applies the coating agent, wherein the application device includes a print head that discharges the coating agent from a plurality of coating agent nozzles included on the print head, and further wherein:
- the plurality of coating agent nozzles are arranged in at least four nozzle rows, and
- the coating agent nozzles are supplied with the coating agent by one or more supply lines;
- wherein outer coating agent nozzles in each of the one or more nozzle rows emit less coating agent than inner coating agent nozzles in each of the one or more nozzle rows wherein the print head achieves a trapezoidal layer thickness distribution, and
- the nozzle rows are arranged alternately in the print head rows with rows of large nozzle openings and with rows of small nozzle openings, the rows of large nozzle openings alternate with rows of small nozzle openings and the nozzle rows with large nozzle openings are offset with respect to each other and the small nozzle openings are not offset with respect to each other.
2 more elements
Coating device for coating components with a coating agent, comprising:
- an application device that applies the coating agent, wherein the application device includes a rotatable print head that discharges the coating agent from a plurality of larger coating agent nozzles and a plurality of smaller coating agent nozzles included on the print head, the rotatable print head including a perimeter and an axis of rotation and further wherein:
- the plurality of smaller coating agent nozzles are in one or more nozzle row, and
- the larger and smaller coating agent nozzles are supplied with the coating agent by one or more supply lines;
- wherein larger coating nozzles are arranged proximate the perimeter of the rotatable print head and the smaller nozzles arranged proximate the axis of rotation of the rotatable print head.
