Each side is capable of loading all panels from one complete cab. An ABB inverted track-mounted robot plays the water jet on the panels to cut them. A computerized control system contains programmed cutting patterns that direct the robot's movements for each type of panel. This is more economical and speedier than using punch tools that would have to be changed to cut a different panel type. In between placing the panels, self-diagnostic equipment ensures that the robot will be in the correct position for the next cut.
Water drains through an outlet on the bottom of the self-contained cutting box.
Semiautomatic equipment removes scrap metal, and an extractor fan mounted on the ceiling provides ventilation. In addition to providing greater flexibility than standard punching or milling tools, the ABB robotic water jet also reduces inventory cost at the Oskarshamn plant by enabling Scania to stock only three rear and eight side panels to meet customer demand. The Type 475 high-flow solenoid valves being introduced to the U.S. market by Burkert Contromatic USA in Irvine, Calif., offer original equipment manufacturers a service life 50 percent longer than conventional plunger valves, according to the company. Netherlands-based Campina uses the valves in dairy processing, while the German firm Hoechst uses it to process chemicals. This design allows the electromagnetic components to be completely isolated from the fluid.
