A new system of two servo robots mounted on a single traverse beam is aimed at two-shot molding or partshandling tasks inside and outside of the mold. The system was introduced by the Japanese parent of Yushin America Inc., Cranston, R.I., at the recent Platex show in Osaka. Its new RA II-a-150-DW (Double-Wing) is designed for presses from 220 to 550 tons and features two three-axis robots, each with 11-lb payload capacity and pneumatic wrist fl ip. A sprue picker with each robot provides a total of eight axes of motion. Users can program both robots to move in and out of the mold simultaneously, or one robot can retrieve a part from the mold and hand it off to the second robot for transport outside the molding area. The robots have traverse strokes of 1400 or 1500 mm, vertical stroke of 850 mm, and strip stroke of 508 or 578 mm. Both robots are programmed from a single controller with new software that prevents collision and displays information on both robots on one screen. Tel: (401) 463-1800 . www.yushin.com

Editor PickIf Two Arms Are Better Than One, Are Four Better Than Two?
Robots with two main arms have proven useful in applications ranging from stack molds to IML to insert molding and performing a variety of post-mold operations. The concept has evolved to the point that a single robot chassis can have two kick assemblies with one or two arms apiece.
