Motoman Robots Handling and Palletizing

Motoman SP100X robot equipped with custom multi-function gripper palletizes cases of pickled food products into the appropriate stacking pattern on one of two pallet stations.Cases of Pickled Food Products

Robot picks smaller 8-38 lb cases individually, and palletizes them at a line rate of 10 per minute (600 per hour). Robot picks tall, narrow 20-lb cases two at a time and palletizes them at a rate of 20 per minute (1,200 per hour). Robot system reliably performs back-breaking palletizing job that people did not want to do. Employee turnover is reduced, employee satisfaction is increased, and injuries are significantly reduced. Palletizing robot enabled plant to increase production. As a result, unit cost decreased and company was able to hire more workers for processing line. System changeover is quick and easy; operator simply selects different robot program using robot teach pendant and the system is ready to run the next batch.

Fixtures/Tooling Details

Custom-designed multi-function gripper uses a single-zone vacuum gripper along with a pneumatically actuated mechanical side plate to securely grip and transfer the cases, regardless of their size or weight. The robot gripper picks the smaller, lighter cases that weigh 3.6-17.2 kg (8-38 lbs) each individually, and palletizes them at a line rate of 10 per minute (600 per hour). The robot palletizes the tall, narrow 9.1-kg (20-lb) cases that each contain two 4-liter/1-gallon jars two at a time. Design uses both vacuum and side plate grippers to ensure that the robot will never drop a case, preventing breakage of the jars of pickled food product inside the cases.
