Robot Controller Adds Two Part-Handling Functions

摘要

Two new real-time functions addressing part removal and placement tasks have been added to the new R8 robot control from Wittmann Battenfeld, Torrington, Conn. Its new SoftTorque function compensates for varyingejector strokes and velocities by allowing the position of the robot and end-of-arm-tooling (EOAT) to vary. Normally, automation systems hold the EOAT to an exact position even though the partrremoval position can vary slightly with the ejector stroke on each cycle. With SoftTorque, the kick stroke of the Wittmann Battenfeld W8- series beam-mounted robot releases the brake and adopts a free state of movement while the ejectors to push the parts , onto the EOAT. The free state prevents stressing the robot and damage to the part surface.
