Patent number: 9375746Abstract: Paint booths for applying paint to an object, as well as methods for degrading coating operations associated with a paint booth, are disclosed. Paint booth may generally include one or more robot rails positioned parallel to the path of the conveyor, and one or more robots positioned on at least one of the rails. Robots may be configured to simultaneously apply a first paint layer to the interior and exterior surfaces of the object. Paint booths may further include one or more additional robots positioned on at least one of the rails and configured to simultaneously apply a second paint layer to the interior and exterior surfaces of the object.Type: GrantFiled: June 4, 2009Date of Patent: June 28, 2016Assignee: Durr Systems GmbHInventors: Robert Heldt, Jan Grigoleit, Vassilios Sougioltzis, Thomas A.

Patent number: 9126217Abstract: An ink jet is disclosed that may be placed in a bell plate of a rotary atomizer and, when thus placed, forms an annular gap between the ink jet and a distribution disc recess of the bell plate. An exemplary illustration has a common rinsing agent channel running in the ink jet for conducting a rinsing agent for rinsing the bell plate, a first rinsing agent outlet that is supplied with rinsing agent by the common rinsing agent channel and directed forward in a substantially axial direction toward a distribution disc of the bell plate, and a second rinsing agent outlet that is supplied with rinsing agent by the common rinsing agent channel. In the installed state, an exemplary second rinsing agent outlet may empty into the annular gap between the distribution disc recess and the ink jet in order to clean the annular gap with the rising agent.Type: GrantFiled: August 2, 2010Date of Patent: September 8, 2015Assignee: Durr Systems GmbHInventors: Hans-Jürgen Nolte, Robert Heldt

Patent number: 8590813Abstract: A rotary atomizer applies particulate paints with good color matching by reducing paint droplet size deviation and then optimizing the other paint spraying parameters. Paint droplet size parameters are reduced by using a bell cup having reduced flow deviations, including an overflow surface having a generally constant angle between a deflector and an atomizing edge.Type: GrantFiled: March 7, 2012Date of Patent: November 26, 2013Assignee: Dürr Systems, Inc.Inventors: Kurt Vetter, Rolf Schneider, Andreas Fischer, Robert Heldt

Publication number: 20080023571Abstract: A paint delivery and application apparatus, wherein the apparatus includes a source of paint, a paint applicator, a supply line interconnecting the source of paint and the applicator and at least one pig in the supply line, wherein the paint pushes the pig from adjacent the source of paint to the paint applicator and a source of purging solvent delivering a small volume of purging solvent to the supply line when the pig is adjacent the source of paint adjacent to and upstream of the pig acting as a lubricant, reducing chattering and skipping of the pig and extending the life of the pig. Where the apparatus includes two pigs, purging solvent is delivered between the pigs adjacent the applicator, the pigs are delivered to adjacent the source of paint and a small volume of solvent is then delivered from between the pigs upstream of the pigs.Type: ApplicationFiled: January 10, 2005Publication date: January 31, 2008Inventors: Robert Heldt, Rainer Melcher, Manfred Michelfelder, Robert Brady

Publication number: 20070082143Abstract: A coating means supply device, in particular for a paint facility, having a coating means meter that meters coating means to be applied to application equipment. The coating means supply device includes a coating means reservoir for holding the coating means and for supplying the coating means meter with the coating means. During application of coating material to equipment, the coating means reservoir is at ground potential and is located upstream from the coating means meter, which is at high-voltage potential. The reservoir is connected via an insulating path to the coating means meter. The coating means meter is at ground potential when the coating means reservoir supplies coating means to the coating means meter. Before the coating means meter is returned to a high-voltage potential for continued application of coating material, the insulating path is emptied to again insulate the coating means meter from the coating means reservoir.Type: ApplicationFiled: October 6, 2006Publication date: April 12, 2007Applicant: Durr Systems, Inc.Inventors: Michael Baumann, Frank Herre, Herbert Martin, Rainer Melcher, Manfred Michelfelder, Bernhard Seiz, Richard Ostin, Robert Heldt

Publication number: 20060086407Abstract: The disclosed apparatus includes a supply line (22) between a source of liquid paint (64) and an applicator (62) having at least two pigs (20A and 20B) and a source of liquid solvent (60) which delivers solvent (60) between the two pigs (20A and 20B) and the pigs (20A and 20B) are driven by paint (80) from adjacent the paint source (64) to the applicator (62). The apparatus further includes a second source of liquid solvent (60) which delivers solvent (60) between the pigs (20A and 20B) adjacent the applicator (62) and the pigs (20A and 20B) are returned through the supply line (22), thereby flushing the supply line (22). In the disclosed embodiment, the source of liquid paint (64) is a piston dosing device (70) which receives paint (80) from a color changer or the like and delivers a predetermined volume of paint (80) to the applicator (62). The delivery line (22) preferably includes a friction resistant inner layer, an intermediate dielectric layer and a protective outer layer.Type: ApplicationFiled: May 6, 2003Publication date: April 27, 2006Inventors: Frank Herre, Rainer Melcher, Herbert Martin, Michael Baumann, Richard Ostin, Robert Heldt, Manfred Michelfelder, Joachim Hering

Publication number: 20050173018Abstract: A paint delivery and application system including a color changer (20), at least two paint cannisters (34, 36) and a paint applicator (30), a first pair of supply lines (38, 42) connected between the color changer (20) and the paint cannisters (34, 36) and a second pair of supply lines connecting the paint cannisters and the paint applicator (30), wherein the paint cannisters operate in tandem permitting delivery of a first paint to one of the paint cannisters while a second paint cannister is electrically isolated from the color changer (20) and is delivering paint to the applicator (30). In one disclosed embodiment, the delivery line from the paint cannisters to the applicator includes two pigs and solvent is delivered between the pigs, such that this system is self purging.Type: ApplicationFiled: May 6, 2003Publication date: August 11, 2005Inventors: Frank Herre, Rainer Melcher, Herbert Martin, Michael Baumann, Manfred Michelfelder, Richard Ostin, Robert Heldt, Joachim Hering, Hans Nolte
