The disclosure concerns a coating device and a corresponding coating process for coating components, in particular motor vehicle body components, with a coating agent (e.g. paint), with a coating robot with a first printhead which is mounted on the coating robot. The disclosure provides that the first printhead is exchangeably mounted on the coating robot and can be exchanged for a second printhead during a color change. Another variant of the disclosure, on the other hand, provides for a second printhead to be mounted on the coating robot in addition to the first printhead, the two printheads each applying a specific coating agent in order to enable a color change without changing the printhead.

Coating device and corresponding coating process

The disclosure relates to an application device for the application of an application medium onto a component, preferably for application of a paint onto a motor vehicle body component, comprising: at least one print head for application of the application medium preferably in series and for mounting on an application robot, and at least two nozzle rows which can be moved by the application robot, wherein the at least two nozzle rows comprise a first nozzle row with several nozzles for the output of application medium jets and at least one further nozzle row with several nozzles for the output of application medium jets. The application device is characterised in particular in that at least one nozzle row of the at least two nozzle rows is movable for the purpose of position adjustment of the nozzles of the first nozzle row and the nozzles of the at least one further nozzle row.

Print head with a displacing mechanism for a nozzle row

The disclosure relates to a painting installation for painting components with a paint, in particular for painting motor vehicle body components, with a paint booth and an application device, in particular a print head, arranged in the paint booth, for applying the paint to the component located inside the paint booth, the application device operating essentially without overspray, so that the paint applied by the application device essentially completely on the component to be coated without overspray deposits. The disclosure provides that no paint separation is arranged below the first paint booth.

Coating installation and corresponding coating method

The disclosure concerns a coating device for coating components with a coating agent, in particular for painting motor vehicle body components, with a printhead, a multi-axis coating robot and with a robot control which controls the coating robot. The disclosure additionally provides for a separate printhead control which controls the printhead valve of the printhead.

Coating device for coating components

Coating device with printhead storage

Applying a coating medium may include: emission of a coating medium jet from an application device and positioning the application device relative to the component with a particular application distance between the application device and the component, so that the coating medium jet impacts on the component and coats the component. The application distance (d) can be smaller than the disintegration distance of the coating medium jet, so that the coating medium jet impacts with its continuous region on the component.

Application method and application system

The disclosure concerns a coating method and a corresponding coating device for coating components with a nozzle applicator with several nozzles, in particular for painting motor vehicle body components. The disclosure provides that the nozzle applicator is flexibly controlled during the coating method.

Coating method and corresponding coating device

The disclosure concerns an applicator, in particular a printhead, for applying a coating agent, in particular a paint, to a component, in particular to a motor vehicle body component or an attachment for a motor vehicle body component, having a plurality of nozzles for applying the coating agent in the form of a coating agent jet, and a plurality of coating agent valves for controlling the release of the coating agent through the individual nozzles, and having a plurality of electrically controllable actuators for controlling the coating agent valves. The disclosure provides that a control circuit for electrically controlling the actuators is integrated in the applicator.

Applicator comprising an integrated control circuit

The disclosure concerns an applicator (e.g. print head) for applying a coating agent (e.g. paint) to a component (e.g. motor vehicle body component), having a nozzle chamber with a plurality of nozzles for dispensing the coating agent in the form of continuous jets or droplets, the coating agent flowing during operation through the nozzle chamber to the nozzles so that the nozzle chamber is filled with the coating agent during operation. The print head further comprises a plurality of slidable valve needles associated with the individual nozzles and selectively opening or closing the respective nozzle depending on the position of the valve needles. Furthermore, the print head according to the disclosure contains an actuator chamber for receiving actuators for displacing the valve needles. In addition, the applicator according to the disclosure has a sealing element which fluidically separates the actuator chamber from the nozzle chamber in order to avoid contamination of the actuator chamber with the coating agent in the nozzle chamber. The disclosure provides that the sealing element is designed such that the individual valve needles can be displaced independently of one another without a displacement of one of the valve needles impairing the opening and closing of the nozzles at the adjacent valve needle.

Applicator comprising a sealing membrane

The disclosure concerns an applicator (e.g. printhead) for applying a coating agent (e.g. paint) to a component (e.g. motor vehicle body component), having at least one nozzle row with a plurality of nozzles for dispensing the coating agent in the form of a jet in each case, the nozzles being arranged along the nozzle row and in a common nozzle plane, and having a plurality of actuators for controlled release or closure of the nozzles. The disclosure provides that the individual actuators each have an outer dimension along the nozzle row which is greater than a nozzle distance along the nozzle row.

Applicator with a small nozzle distance

The disclosure relates to a perforated plate for an application apparatus for the application of a fluid onto a component, preferably a motor vehicle bodywork and/or an add-on part therefor. The perforated plate comprises at least three through-holes for the passage of the fluid, wherein the through-holes are assigned to a row of nozzles with a central region and two edge regions, wherein the at least one outermost through-hole in at least one edge region has at least one reference opening diameter that is smaller than at least one reference opening diameter of at least one through-hole in the central region.
