Coating device and corresponding coating process

A coating process for coating components with a coating agent, the coating process comprising the following steps:

• a) moving a first printhead with at least one nozzle and an associated printhead valve by means of a multi-axis coating robot over a surface of the component to be coated, and
• b) discharging a coating agent jet of a first coating agent through the nozzle of the first printhead onto the surface of the component to be coated,
• c) a color change with the following steps:
• switching coating agent delivery from said first printhead to a second printhead mounted on the same coating robot for subsequent delivery of a coating agent jet of a second coating agent through said second printhead,
• inserting the first or second printhead into a cleaning device,
• cleaning the first or second printhead in the cleaning device,
• collecting and disposing of the liquids applied in the cleaning device, and
• pre-filling with a new coating agent in the cleaning device.

• c) a color change with the following step:
• exchanging the first printhead by a second printhead for the subsequent delivery of a coating agent jet of a second coating agent through the second printhead onto the surface of the component to be coated, including depositing the first printhead from the coating robot in a deposit device and taking-up the second printhead by the coating robot, and
• d) bathing or at least partially immersing the deposited first or second printhead in a liquid bath in the deposit device in order to prevent the coating agent from drying in the deposited first or second printhead.
