The disclosure relates to a bell plate for a rotary atomizer for applying a coating agent (e.g. paint) to a component (e.g. motor vehicle body component). The bell plate according to the disclosure comprises a metallic base body and a transponder which can be read out wirelessly and is integrated in the bell plate. The disclosure provides that the transponder is arranged on the front side in the base body or is embedded in the outer outer circumferential surface of the bell plate, which facilitates the read-out of the transponder. Furthermore, the disclosure comprises a suitably adapted atomizer cleaning device having an antenna for reading out the transponder in the bell plate. Finally, the disclosure also comprises a correspondingly adapted operating method.

Bell plate, atomizer-type cleaning device, and associated operating method

The disclosure relates to a collecting device for collecting fluid media (e.g. rinsing agent, paint residues), which are produced when rinsing an atomizer (e.g. rotary atomizer) in a painting plant. The collecting device according to the disclosure comprises a collecting container with an insertion opening at the top of the collecting container for inserting the atomizer into the collecting container. Furthermore, the collecting device according to the disclosure comprises a lateral container wall which externally delimits the collecting container and is substantially impermeable to paint in order to prevent paint from escaping from the collecting container. The disclosure provides that the lateral container wall of the collecting container is at least partially air-permeable so that moist air can escape from the interior of the collecting container to the outside.

Collection apparatus for rinsing media of an atomizer

The disclosure relates to an applicator (RZ), in particular a rotary atomizer, for the application of a coating agent, in particular a two-component paint, comprising a first coating agent connection (SL) for feeding a first coating agent, in particular a basic resin of a two-component paint, a first coating agent strand (L-L), which extends in the applicator (RZ) from the first coating agent connection (SL) and carries the first coating agent, and a first valve (SLV), which is arranged in the first coating agent strand (L-L) and controls the flow of the first coating agent, wherein the first valve (SLV) can be controlled by a first control signal. It is proposed that a first pressure-relief valve (SLV), which is actuated by its own medium, is arranged in the first coating agent strand (L-L) and, to avoid a problem being caused by excessive pressure, opens automatically when the pressure upstream of the first pressure-relief valve (SLV) exceeds a certain maximum pressure.

Applicator, in particular rotary atomiser

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

The disclosure relates to a coating agent valve () for controlling a flow of fluid of a coating agent mixture consisting of two coating agent components (H, SL), in particular a two-component paint consisting of a master batch (SL) and a hardener (H). The coating agent valve according to the disclosure () comprises a valve seat, a displaceable valve head (), a valve drive () for displacing the valve head () and a displaceable valve needle () which connects the valve drive () to the valve head () and moves the valve head () in correspondence with the valve drive (). The disclosure provides for an automatic reduction in pressure in order to avoid excess-pressure damage upstream from the coating agent valve ().

Coating agent 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

A cleaning device for cleaning an atomizer, in particular a rotary atomizer, is provided. The cleaning device includes a wet cleaning station having at least one cleaning nozzle for the wet cleaning of the atomizer with a cleaning fluid. The atomizer is introduced into the wet cleaning station in an introduction direction. The cleaning nozzle has a rotatable cleaning trunk for dispensing the cleaning fluid. The cleaning device, in some embodiments, also includes a dry cleaning station. A corresponding operating method is also provided.

Cleaning device and associated operating method

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 painting-installation cleaning system is provided for cleaning at least one component of a painting installation, in particular at least one component of a painting robot or of a handling robot, characterized by at least one dry-ice nozzle for producing a dry-ice jet which cleans the component.

Dry-ice cleaning in a painting installation

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.
