  • Patent number: 9505020
    Abstract: The exemplary illustrations relate to an applicator for applying a coating to a component, for example for applying a sealing compound to an edge-raised seam on a rear side of a motor vehicle body component through a gap between two overlapping motor vehicle body components, with a nozzle for dispensing the coating means onto the rear side of the component and with an elongated curved nozzle carrier in order to position the nozzle on the rear side of the component to be coated, starting from the front side of the component to be coated. It is proposed that the nozzle carrier be curved a plurality of times such that the applicator can be guided through the gap.

  • Patent number: 8356571
    Abstract: An applicator is disclosed for applying a coating agent, such as a sealant, to a component, such as a flanged seam of a motor vehicle body component. The applicator includes a nozzle for delivering the coating agent on to the component and a carrier. The carrier may be guided by a multiple-axis robot in operation, with a joint located kinematically between the carrier and the nozzle, thereby permitting the nozzle to move to avoid contact with a component being coated.

  • Patent number: 8028651
    Abstract: A metering system for a coating installation for coating components such as vehicle body parts contains an applicator which applies the coating material supplied to it with a volumetric flow metered on-demand, a regulated first metering device which adjusts the pressure or the volumetric flow of the coating material to be applied by the applicator based on setpoints which are specified by automated installation controls, a transducer to generate a reading which matches the pressure or the volumetric flow of the coating material flowing to the applicator and a control device for regulating the metering device as a function of the specified setpoints and of the reading from the transducer. A second metering device is connected at the outlet of the regulated first metering device for the coating material flowing to the applicator which controls the pressure or volumetric flow of the said applied coating material for precision metering of the coating material applied as a function of the specified setpoints.
