Patent number: 11383258Abstract: A next generation painting robot with advanced fluid delivery system, enhanced kinematics and a service airlock compartment. The painting robot includes a fluid delivery system which places color changing valves and pumping hardware on the back side of the robot's mounting pedestal, where it can be serviced without a technician having to enter the spray booth. Additionally, the robot enables routine cleaning and maintenance to be performed without personnel entering the spray booth and without stopping the vehicle conveyor, due to simplified outer arm design, improved home positioning and an airlock booth adjacent to the robot pedestal. Service personnel can clean and service the applicator and other components on the outer arm from the airlock booth, while other robots continue painting parts moving on the conveyor, without allowing fume-laden vapors into the operator aisle.Type: GrantFiled: May 3, 2019Date of Patent: July 12, 2022Assignee: FANUC AMERICA CORPORATIONInventor: Scott J.

Patent number: 11161135Abstract: A next generation painting robot with advanced fluid delivery system, enhanced kinematics and a service airlock compartment. The painting robot includes a fluid delivery system which places color changing valves and pumping hardware on the back side of the robot's mounting pedestal, where it can be serviced without a technician having to enter the spray booth. The fluid delivery system also allows smaller and lighter robot arms, and is designed to minimize paint waste and wait time during color changes. The robot also features kinematics providing redundant inner arm rotation. The arm kinematics, along with the smaller arms, a paint supply line routed through the center of first and third arm joints, and optimized motor conductor routing, dramatically improve near reach flexibility. The improved near reach flexibility in turn allows a smaller spray booth than possible with previous robot architectures.Type: GrantFiled: May 3, 2019Date of Patent: November 2, 2021Assignee: FANUC AMERICA CORPORATIONInventors: Scott J. Clifford, Stan H. McClosky, David A. Carbery

Publication number: 20190337004Abstract: A next generation painting robot with advanced fluid delivery system, enhanced kinematics and a service airlock compartment. The painting robot includes a fluid delivery system which places color changing valves and pumping hardware on the back side of the robot's mounting pedestal, where it can be serviced without a technician having to enter the spray booth. The fluid delivery system also allows smaller and lighter robot arms, and is designed to minimize paint waste and wait time during color changes. This is accomplished by an arrangement of shut off valves and pumps, including a pump for paint and a high-efficiency pump for low viscosity solvent, operating in a sequence to push paint through a minimal-length supply line to the applicator, using almost all of this paint for painting the part, before returning to a cleaning stand and expelling the remaining paint and solvent in the supply line.Type: ApplicationFiled: May 3, 2019Publication date: November 7, 2019Inventors: Scott J.

Patent number: 7611069Abstract: An apparatus and method for forming and controlling a pattern for spraying surfaces with a fluid uses a rotary atomizer spray head having an air shaping ring with shaping air nozzles inclined in a direction of rotation of a bell cup to direct the air onto the cup surface near the cup edge. The air shape ring optimizes the shape air control to create a stable, focused pattern that minimizes robot speed while maintaining high transfer efficiency. Nozzles extending parallel to the axis of rotation of the bell cup can be provided. Selection of the shaping air flow rate produces broad, collapsed and tubular spraying patterns.Type: GrantFiled: August 9, 2005Date of Patent: November 3, 2009Assignee: Fanuc Robotics America, Inc.Inventors: Scott J.
