ROBOT OFFERS SYNCHRONIZED FREE MOTION DURING EJECTION

For applications requiring fully synchronized free motion of the robot during part ejection, Wittmann has introduced an optional Ejector PartTrack function to several of its top entry robots (W621 – W643) with CNC 6 and higher controls. Ejector PartTrack allows the robot to come down into the mold area, move forward, grip the molded part and then disengage the drive but keep the encoder signals live for position and speed until the signal is received to re-engage the drive.

The system can be configured to re-engage at any point in the ejector cycle, and to resume the robot’s motion at any speed.

Ejector PartTrack has the added safety benefit of preventing damage to the stationary mold half. The robot monitors this position and prevents the arm from contacting the mold.

The added flexibility of the robot is further enhanced by the Wittmann TeachBox graphical programming pendant, which allows simple set-up and operation, including changes on the fly of the robot Ejector PartTrack parameters.

MORE FLEXIBILITY IN EOAT DESIGN

SAS Automation’s DX robotic gripper platform uses a new D-shaped frame profile which offers up to 8 sides for mounting robotic components. In addition, two sides are at opposite 45 degree angles which allow even greater flexibility in mounting angles. The gripper platform is designed for heavy and bulky applications.

The DX platform also allows for back-to-back mounting of the D-shaped profiles (creating a configuration similar to the letters “db”).

All sides have X nut channels to accept SAS’s full line of gripper components.
