MAN using the latest Dürr painting technology for its cabs Dürr’s scope of delivery starts with pre-cleaning. Two robots of the type EcoRS 210 remove the dust and dirt particles from the bodies using blade brushes prior to painting. The tried-and-tested brushes from the passenger car segment can adapt very flexibly to the contours of the body, and are being used for the first time for truck cabs in the Munich plant. © Durr

ürr is installing its innovative EcoDry X dry separation system in truck manufacturer MAN’s new paint shop for truck cabs in Munich now for the first time in Germany. EcoDry X is a semiautomatic system based on cardboard filter technology. Dürr’s scope of delivery includes complete system configuration, conveyor technology, pre-cleaning, sealing, and painting stations as well as the associated application technology complete with paint and PVC delivery. “With this concept, we are supplying a highly efficient system where the customers benefit from our consistent components,” says Dürr Global Customer Director for Trucks, Andrea Klein, explaining the reasons behind the company’s selection as the system supplier.
Four EcoRS 30 robots are used in the PVC line. They apply roof and underbody seams and seal welded seams inside the body. This prevents water and moisture getting into the cab. The robots are equipped with the flexible applicator EcoGun 3D, which can apply the material at three different application angles of 0, 45, and 90 degrees. Up to three nozzles for different seam thicknesses are Integrated application 1 integrated in the Dürr technology for sealing applicator in the 3D and paint application, Figure 1: EcoDry X – the intentionally simple and robust paint overspray separation system. version. identical robot “The standardized platforms for preEcoGun 3D is suitable cleaning and sealing as for all fields of application in seam sealing,” says Andrea Klein, describing well as the standardized controller technology not only reduce the variety the benefits of the applicator. “This means that it is not necessary to of spare parts, but also simplify all future maintenance tasks. Needing stock spare parts for multiple models”. just one service technician for all applications means top efficiency both The scope of delivery also includes a line for sealing the door sill. for MAN as the plant operator and for Dürr as the technology supplier. The quality standards at this station are particularly high, since “Having the same operating software for all applications also significantly incorrectly executed seams are visible when the door is opened. Suitable reduces the training costs for the plant operators,” adds Andrea Klein, fine seam nozzles are therefore used for applying these visible seams. explaining the benefits of the concept.
