If Two Arms Are Better Than One, Are Four Better Than Two?

摘要

For many years, Cartesian-style robots have been the primary design for injection molding machines' take-out robots. They normally were comprised of three linear axes: a strip stroke, a lifting stroke, and conveying stroke. The mold would open and the lifting stroke would position a gripping device to secure the molded parts in the mold. The strip stroke would move back, removing the molded parts and then the lifting stroke would retract, allowing the mold to close and continue the cycle. The conveying stroke then moved the parts, carried by the lifting and strip stroke axes, to an area where they could be discharged.
