A new Windows-based robot controller that can also control up to 31 auxiliary devices is new from Harmo of Japan, represented here by AEC, Wood Dale, Ill., and Sterling, New Berlin, Wis. Harmo also introduced a new sprue picker. The HRS-400 i-Controller is designed initially for Harmo's HRX-I line of three-axis servo robots but also works with all Harmo downstream devices including its line of conveyors, box fi llers, dryers, hopper loaders, granulators, and mold-temperature controllers. It communicates through an RS435 port or wireless internet connection. The unit is programmed through a hand-held touchscreen pendant and allows users to build their own program screens. ]]Harmo also came out with the EX line of economical pneumatic sprue pickers. Programming and operation are through a redesigned hand-held HRS pushbutton pendant that uses a simple input/output signal from the press. It comes in two versions: Four stand-alone EXR models are suited to presses from 44 to 330 tons and handle payloads up to 2.2 lb. EXG models come mounted on the same beam as a three-axis robot and handle up to 1.1 lb. AEC: (630) 595-1060/www.aecinternet. com . Sterling: (414) 354-0970 . www.sterlco.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.
