Palletizer for Rolled Roofing Case Study

MESH designed, manufactured, integrated and started-up a custom engineered gantry style rolled roofing palletizing cell with the following specifications.  The gantry was programmed to receive data from the customer’s system as to type of roll and pallet pattern.   After receiving data the gantry would pick up an empty pallet, place it on one of two output conveyors and proceed to pick up a rolled roofing product from the infeed conveyor.   After completion of the complete pallet, the system would convey the finished pallet out of the cell.   Two finished goods pallets could be stacked at any one time due to the dual outfeeds.
