Thin fingers carefully lift cardboard cartons
Article Type: New products From: Industrial Robot: An International Journal, Volume 39, Issue 1
SAS Automation has introduced a thin metal-fingered gripper that can lift tough-to-lift cartons such as plastic bins, slip-top cartons or even unsealed cartons (Figure 2). Other carton-lifting devices frequently employ vacuum cups which do not work well on these types of cartons. The SAS Automation design employs thin metal panels which slip down the sides of the carton or cartons to be lifted. A welded aluminum frame provides strength and rigidity while keeping the weight of the end-of-arm device low to maximize actual payload possible.
The carton gripper can lift up to 25 kg loads. The stationary metal fingers or bolster plates are coated with a fine abrasive surface to enhance lifting, while requiring only a narrow gap between cartons for access. The moving fingers or bolster plates are powered with self-guided pneumatic cylinders for in-line clamping pressure and coated with a bonded rubber surface.
The gripper can be designed for a specific carton size or for a range of sizes, depending on the application requirements. For slip-top cartons, the moving bolster plates include a rotating finger to secure the bottom for palletizing operations.
The pneumatic control valves are available in Discrete I/O, DeviceNet or Ethernet versions to match the controller protocol. For more information on the SAS Automation carton gripper, please visit: www.sasgripper.com
