Motoman Robot Handling and Case Packing

Six-axis Motoman HP165 robot packs bundles of shipping envelopes into cases or gaylords (shown above) and adds tier sheets between layers, as required.Bundles of Shipping Envelopes

System fully automates case and gaylord packing operations and meets or exceeds all project goals and objectives. System achieves cycle time of 9.0-9.5 seconds for gaylords, with complete gaylord fill of 25-count bundles in 11.74 minutes (14.9% faster than 13.8 minute requirement), and 50-count bundles in 6.5 minutes (47.1% faster than requirement). System achieves cycle time of 9.0 seconds to pick and place a stack of eight bundles. Overall case packing rate is 5 cases per minute.

Fixtures/Tooling Details

Motoman Robotics provided one set of custom end-of-arm tooling for case packing and one set for gaylord packing. Manual changeover is required. Case packer: single-zone mechanical paddle gripper handles eight 25-ct bundles at a time. Pneumatic paddles compress stacks to facilitate case loading. Gaylord packer: vacuum gripper handles 12 (25- or 50-ct) bundles at a time in a 4 x 3 matrix. Layers are opposed 180° to avoid stack-up. Same gripper also handles tier sheets between layers, as required.
