The disclosure relates to a coating method for coating a component with a coating agent, comprising the following steps: moving an application device over a component surface of the component to be coated, delivering a coating agent jet (9) from the application device to the component surface that is to be coated, defining switching points on the component surface for initiating a switching action, in particular for switching on or switching off a coating agent jet, and performing the switching action when one of the switching points is reached.

The disclosure provides the following steps: marking the switching points on the component surface by generating a switching marking on the component surface at the individual switching points, detecting the switching markings corresponding to the individual switching points during movement of the application device, and performing the switching actions when the switching markings are detected on the component surface.

The disclosure further includes a corresponding coating installation.

The invention relates to a process for spraying an emulsion of water insoluble composition, such as an emulsified resin, with a centrifugal atomizer. The centrifugal atomizer comprises a housing, a rotary disc provided in a recess of the housing. An emulsion of a water insoluble composition is supplied to a chamber or formed in the atomizer, the chamber being formed between a front face and a cone of the rotary disc. A mist of air and an aqueous liquid is sprayed in the recess of the housing. The mist flushes the atomizer and limits or avoid water insoluble composition build-up. The invention also relates a centrifugal atomizer system adapted to perform such process.

A shaping air ring for a rotary bell atomizer spray device includes a plurality of circumferentially spaced nozzles disposed in the shaping air ring, wherein each nozzle has a mix chamber, at least one inlet on an upstream end of the mix chamber, and an outlet at a downstream end of the mix chamber. First and second air flows are provided to the mix chamber through the at least one inlet and a combined air flow is discharged through the outlet. The combined air flow shapes the spray pattern of the liquid sprayed by the rotary bell atomizer spray device.

The present invention solves a problem of a trade-off between increases in paint discharge rate and maintenance of painting quality. A rotary atomizing electrostatic applicator includes a bell cup 10 whose back 10a is hit by atomization air SA-IN at an angle of 90 degrees or less; and first air holes 30 adapted to discharge the atomization air SA-IN directed at the back 10a of the bell cup, wherein the first air holes 30 are arranged at equal intervals on a circumference centered around a rotation axis of the bell cup 10, the first air holes 30 are oriented in a direction opposite to a rotation direction of the bell cup 10; and the atomization air SA-IN discharged through the first air holes 30 is twisted in the direction opposite to the rotation direction of the bell cup 10 at an angle of 50 degrees or more and less than 60 degrees.

An electrostatic coater capable of realizing high-level coating quality is provided. Shaping air SA, discharged from an air port, is directed radially outward. An elevation angle thereof preferably ranges from 10 to 20 degrees. Further, the shaping air SA is a flow in a state of being twisted in a direction opposite to the rotation direction R of a bell cup. The twisting angle about the axis O of the bell cup preferably ranges from 38 to 60 degrees. A liquid thread of paint extends radially outward from the outer peripheral edge of the bell cup, and the paint separated from the tip end thereof becomes a particle. It is preferable that the shaping air SA collides with the paint particle at a point P where the momentum of the paint particle is decreased of the paint particle is decreased.

The disclosure relates to a rotary atomizer for applying a spray jet of a coating agent (e.g. paint) to a component (e.g. motor vehicle body component). The disclosure provides that the construction dimensions of the rotary atomizer are coordinated in such a way that the air pressure at the outlet opening of the paint nozzle during operation is lower than the air pressure in the nozzle chamber of the bell cup and in the external rinsing channels in order to prevent a backflow of the coating agent from the outlet opening of the paint nozzle backwards in the direction of the nozzle chamber due to the pressure difference.

The disclosure relates to a bell cup for a rotary atomizer for painting components, having the following features: a hub for rotatably mounting the bell cup on the rotary atomizer, so that the bell cup is rotatable about an axis of rotation, an annular circumferential spraying edge for spraying the paint in the form of a spray jet, and a circumferential outer lateral surface which widens along the axis of rotation in the distal direction towards the spraying edge,
The disclosure provides that the outer lateral surface of the bell cup is divided into different sections, which are angled differently. Furthermore, the disclosure comprises a rotary atomizer with such a bell cup, a painting installation and a corresponding painting method.

A shaping air ring for a rotary bell atomizer spray device includes a plurality of circumferentially spaced nozzles disposed in the shaping air ring, wherein each nozzle has a mix chamber, at least one inlet on an upstream end of the mix chamber, and an outlet at a downstream end of the mix chamber. First and second air flows are provided to the mix chamber through the at least one inlet and a combined air flow is discharged through the outlet. The combined air flow shapes the spray pattern of the liquid sprayed by the rotary bell atomizer spray device.
