  • Patent number: 10302215
    Abstract: Exemplary illustrations of a fluid valve, e.g., a return valve for returning residual paint, rinsing agent, and compressed air from a paint line when changing color in a painting system, are disclosed. An exemplary fluid valve may be adjusted between an open position, in which the fluid valve is at least partially open, e.g., for rinsing a paint line with a rinsing agent and for pressurizing the paint line with a new color for the color change, and a closed position, in which the fluid valve is closed, e.g., for applying the new color after the color change. An exemplary fluid valve may switch to the closed position, upon actuation by the medium thereof, e.g., medium flowing through or present in the valve. In another example, a fluid valve may close depending on the fluid present at the input side.

  • Patent number: 10232400
    Abstract: A perforated plate is provided for an application device for the application of a coating agent, in particular a paint, a sealant, a glue or a separating agent, to a component, in particular to a motor vehicle body component. The perforated plate contains at least one through-hole for passing the coating agent through and a hole exit opening on the side of the perforated plate that is located downstream with a wetting surface that can be wetted during operation by the coating agent. The through-hole, to reduce the wetting tendency, transitions into a protruding pipe stub or has a structure that reduces the wetting tendency and/or improves the flushability, e.g., a microstructuring or a nanostructuring.

  • Patent number: 10046361
    Abstract: A component is conveyed in a conveyor direction through a painting installation by conveyor. The component surface of the component to be painted is subdivided into surface painting modules which lie one behind the other in the conveyor direction. The individual painting modules of the component surface are painted one after the other using a multi-axis painting robot that has an atomizer. The painting robot guides the atomizer, within each one painting module, along a painting path and across the component surface of the painting module. The painting path has at least one path section running transverse to the component edge. Within the painting module, the painting path can comprise at least one path section that runs substantially parallel to the component edge.
