  • Inventory system with efficient operator handling of inventory items
    Patent number: 9475639
    Abstract: An inventory system can receive a receipt receptacle from a shipping vehicle. The receipt receptacle can be moved to a case shuttle without separating or sorting inventory items in the receipt receptacle.

  • INVENTORY SYSTEM WITH EFFICIENT OPERATOR HANDLING OF INVENTORY ITEMS
    Publication number: 20160145045
    Abstract: An inventory system can include multiple floors. The system can assign operations involving inventory items to a floor based on information about the floor, other floors, the operations, and/or the inventory items. In one example, the system may assign an order to be assembled on a floor based on the floor containing items for the order. Items may be moved to the floor from other floors to complete the order. In another example, a receipt receptacle received from a shipping vehicle can be moved to a rack without separating inventory items from the receipt vehicle. A mobile drive unit can move the rack to a floor based on information known about the inventory items matching criteria about the floor.
