The disclosure relates to a rinsing apparatus for connection to an application-agent main channel of an application-agent changeover unit and preferably for the continuous inflow of a rinsing agent into a flow of rinsing air, having a main line for transporting rinsing air and having a rinsing-agent line for transporting a rinsing agent. The rinsing apparatus is distinguished in particular in that the rinsing-agent line opens out into the main line by way of a mouth opening in order to generate a preferable y continuous flow of a rinsing-air/rinsing-agent mixture for introduction into the application-agent main channel. The disclosure also relates to a corresponding rinsing method.

The disclosure relates to a needle valve for controlling a fluid flow of a coating agent (H, SL) in a painting system, particularly for controlling a fluid flow of a two-component mixture consisting of two coating agent components (H, SL), particularly a two-component paint made from a master batch (SL) and a curing agent (H), comprising a valve seat () and a displaceable valve needle () with a needle stem and a valve head (), wherein the valve head () closes the valve seat () in a closed position of the valve needle (), while the valve head () opens the valve seat () in an opened position of the valve needle (). The disclosure provides a flexible membrane () which surrounds the valve needle () annularly and in a sealing manner upstream before the needle head ().

Needle valve

Valve

Various exemplary illustrations of a coating agent device are disclosed. In one example, a coating agent device may be a coating agent valve, e.g., for influencing the discharge of a coating agent. The coating agent device may include a plug-in or pluggable fastening base configured to facilitate a plug-in or pluggable mounting of the coating agent device. In some examples, the coating agent device may prevent relative rotation of the device relative to a mating component.

Coating agent device and coating device

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.

Fluid valve, in particular a return valve for a painting system

A coating system applicator component, e.g. a valve or bell cup, which may be used to be wetted and/or flown through at least in some sections by a coating agent, is provided. The applicator component includes a cylindrical holding part configured to releasably couple a mount of the coating system, as well as an applicator thread on the holding part. The applicator thread includes first and second applicator flank surfaces each obliquely oriented to a radial direction of the holding part, the first and second applicator flank surfaces being asymmetric about the radial direction of the holding part. The first and second applicator flank surfaces are configured to be parallel to and interface with first and second mount flank surfaces of a thread of the mount, respectively, upon a coaxial, threaded engagement between the holding part and the mount.

Coating system component comprising at least one holding part

A color changer system for a painting robot comprises a color changer. A plurality of color feed lines are included on an inlet side of the color changer. A common color line is included on an outlet side of the color changer, and is configured to forward paint selected by the color changer to an atomizer. A color bar comprises a plurality of docking points supplied by the color feed lines. A color extractor is configured to selectively dock onto one of the docking points of the color bar and, while docked to the color bar, extract paint from an associated color feed line and supply the extracted paint to the common color line.

A coating system component which may be used to be wetted and/or flown through at least in some sections by a coating agent. The component may include a fastening base and at least one holding part which is arranged on the fastening base for being fastened to or in a coating system device. The holding part may be an external thread having a special configuration in order to meet the special requirements of painting facilities, according to various exemplary illustrations. Furthermore, a corresponding coating system device may be provided, to which the coating system component can be fastened in a detachable manner.

Exemplary illustrations directed to a rotary piston pump, e.g., for metering a coating agent in a coating installation, as well as exemplary methods of using the same, are disclosed. An exemplary piston pump may comprise a plurality of pump units, each having one cylinder and one rotary piston which carries out a wobbling or tumbling movement in the cylinder.

A rotary atomizer is disclosed, comprising an atomizer bell and a shaft carrying the same. The rotary atomizer may further include a retainer between the atomizer bell and the shaft, said retainer preventing, e.g., by the action of a centrifugal force, the atomizer bell from detaching itself from the shaft.

Rotary atomizer comprising an atomizer bell and a retainer

An exemplary painting robot and corresponding operating methods for the same are disclosed. The robot may be configured to paint motor vehicle bodies on an outer surface and an inner surface with an atomizer that is guided by the painting robot. According to the exemplary illustrations, the painting robot is suitable for painting the outer surfaces and for painting the inner surfaces of the motor vehicle bodies.
