Motoman Robots Handling

Two Motoman EPL300 robots with multi-function grippers palletize various size logs of packaged book signatures into specified patterns on two different sizes of pallets, and also handle pallets and place slip sheets between layers, as required.Bundles of Printed Documents

Robot palletizing system meets or exceeds project goals and objectives. Customer currently has multiple identical systems installed and more planned. For every product type, robot palletizing system meets or beats required cycle time. System palletizes logs and performs any necessary slip sheet and pallet handling in 25 seconds, which is 7 seconds (nearly 22 percent) faster than the required 32-second cycle time. Highly flexible robot solution palletizes signature lengths ranging from 20-32 inches into more than 30 different pallet pattern configurations (six times more patterns than the five initially required).

Fixtures/Tooling Details

Motoman Robotics provided custom end-of-arm tooling consisting of a pneumatically actuated paddle-style gripper with retractable pallet grabbers to handle individual empty pallets and vacuum cups to handle slip sheets. The paddle gripper is designed to handle one log at a time. Sensors indicate part presence, gripper open/ closed, pallet grippers retracted/extended, and vacuum switches.
