Innovating Warehouse OperationsChapter 6Case Picking Systems Three categories of systems 1 – pick-face palletizing system Motorized pallet jack Operator may walk or ride Pallet Jack picking Pallet train Lift truck (forklift) picking Order picker trucks End of aisle AS/RS (rare) Robotic (expensive / rarely justified)
Innovating Warehouse OperationsChapter 6Case Picking Systems 2 – down-stream palletizing system Pick-to-conveyor (cases are placed on conveyors) Substantially higher productivity Pickers assigned to zones Less travel No palletizing as they pick Case sorting system (pick-to-belt) (sorted into orders) Pick-car; automated case dispensing; tier/layer picking Palletized at or near the shipping dock (manually, mechanically, robotically)
Innovating Warehouse OperationsChapter 6Case Picking Systems 3 – direct loading system Cases conveyed to outbound trailer Used when cases do not need palletizing Can be manual Mechanized Or Robotic
