Carbon Composites Make Robot Arm Light

Touted as the industry's fastest case-packing robots, the KR 40 PA robots use arms made from a carbon-fiber composite.

The resulting mechanism has low inertial forces for fast accel/decel, and the overall center of gravity is relatively low. These four-axis devices are fully programmable and work at rates normally associated with camdriven mechanisms.

The ductile cast-iron base houses three of the unit's four motors. The work envelope accommodates homogenous and mixed palletizing as well as high-speed conveyor-tracking applications. A payload capacity of 40 kg and a reach of 2,091 mm support both 800 and 1,000-mm pallets.
