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 varying ejector 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 part-removal 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.
Wittmann Battenfeld also introduced the PartTrack function that allows the robot to pick or place parts on a moving conveyor. The system uses an incremental encoder that transfers the arbitrary speed of the conveyor belt to the robot control (a camera or sensor gives a start signal). The PartTrack function allows the robot to follow an object and adjust automatically to changing velocity.
