COATING DEVICE AND ASSOCIATED OPERATING METHOD

摘要

A coating device, e.g., for painting motor vehicle bodies, comprises a sprayer for applying a coating material by means of an application element and an internal color-changer valve assembly, said assembly having several color inlets for selecting coating materials of different colors. The internal color-changer valve assembly is integrated into the sprayer and is connected by its outlet to the application element, in order to feed the selected coating material to the application element. Further, an external color-changer valve assembly has several color inlets for selecting coating materials of different colors, said external color-changer assembly having a separate structure from the sprayer and being connected by its outlet to the application element, in order to feed the selected coating material to the application element. An operating method corresponds to the device.

主权项

1. A coating device, particularly for painting motor vehicle bodies, with
a) an atomizer (1) for applying a coating agent by means of an application element (2), and b) an internal colour-changer valve assembly (3) with several paint inlets (4-7) for selecting coating agents of different colours, where the internal colour-changer valve assembly (3) is structurally integrated into the atomizer (1) and connected to the application element (2) at the outlet end, to supply the application element (2) with the selected coating agent, characterised by c) an external colour-changer valve assembly (14) with several paint inlets (4-7) for selecting coating agents of different colours, where the external colour-changer valve assembly (14) is structurally separate from the atomizer (1) and connected to the application element (2) at the outlet end, to supply the application element (2) with the selected coating agent.
