Construction of Robotic Coating System

Location: Red River Army Depot, Texarkana, TX
Client: NAVFAC Southeast

EMR was awarded a task order to design and build an automated vehicle coating application system for two vehicle types. The system had to be fully automated to convey the vehicle into the paint booth, apply a primer coat and then a finish coat of paint to a minimum of 80 percent of the vehicle surfaces, and then convey the painted vehicle to the drying oven. 

EMR demolished the existing floors in the paint booth, drying oven, and approaches on both ends to accommodate the installation of the underfloor vehicle conveyance system. The required reinforcement steel and edge steel, as designated in the structural drawings, was installed prior to the installation of the tracks. Electrical systems included a master control panel, robot control cabinets, conveyor control systems, hazardous location wiring systems located inside the paint booth, interface with the building’s 480-volt power system, fire alarm system, building exhaust systems, and automatic door control systems. The communications and instrumentation systems included both pneumatic and electrical components. These control systems interconnected the conveyance, coating delivery, robotic systems, and the existing building exhaust, fire control, automatic door systems, and the electrical and pneumatic systems. The two-inch pneumatic piping system included automatic air drying and instrument air systems supporting the robots’ operations and the delivery of the coating materials to the robots.
