  • Publication number: 20250041881
    Abstract: 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.

  • Patent number: 12201998
    Abstract: 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.

  • Publication number: 20240408629
    Abstract: 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.

  • Patent number: 12090500
    Abstract: The disclosure relates to a program-controlled coating robot for coating components. A robot path is preset and application parameters observed by the applicator are also preset based on real coating operation during movement along the robot path. There is a virtual determination of a coating result for the predetermined robot path and the predetermined application parameters. The disclosure provides steps for virtual determination of the coating result including generating real spray pattern data and/or reading out real spray pattern data from a database as a function of the predetermined robot path and/or the predetermined application parameters, the read-out real spray pattern data reproducing a spray pattern which the applicator generates during a real coating operation with the predetermined application parameters and/or on the predetermined robot path, and determining the coating result taking into account the real spray pattern data read out from the database or the generated spray pattern data.
