Without question, green was an important consideration in the design of Patagonia’s new distribution space in Reno. But so was flexible and efficient material handling. The automated materials handling systems are designed to sort mailing bags separately from cartons, and to sort product by the method of shipment. The design eliminated the manual handling and sortation of orders.
Receiving: When a shipment leaves a factory for Patagonia, the contract manufacturer forwards an e-mail or fax notification of the shipment. That information is entered into the retailer’s host system, which then creates bar coded labels in advance of the arrival of the shipment. When the shipment hits the receiving dock, cases are unloaded onto extendable conveyors and then palletized in the receiving area. Once the cartons have been palletized, the barcode labels are applied to the cases and scanned to marry the contents of the carton to the pallet. Pallets are now ready for putaway.
Putaway: Pallet loads are put away into very-narrow-aisle racking in the reserve storage area. Each storage location can hold up to three cases. Cases are randomly stored, based on available locations. The lift truck operator scans a bar code label on the case and on the rack to confirm the storage location in the warehouse management system (WMS). Shipments that were inspected by Patagonia at the factory are immediately available for order fulfillment in the WMS. A small sampling of product from shipments that weren’t inspected at the factory is sent to the quality assurance area. That inventory is locked – or unavailable– in the WMS until the sample passes inspection.
Picking: While many retailers pre-allocate inventory for crossdocking, Patagonia waits until inventory passes inspection and is received in the WMS to make allocation decisions across the retailer’s business divisions. Once inventory has been allocated, orders are released into the WMS. Order pickers receive pick labels that are applied to each unit picked. The units are placed on a takeaway conveyor. Full case orders are picked from the reserve storage area and are delivered directly to the shipping area by a lift truck. Individual items are picked from flow racks and static shelving in the pick area. Items picked in the flow rack area are placed on a belt conveyor. Items picked from the static shelving area are picked to a cart. Once the cart is full, the items from the cart are placed on a belt conveyor. In both instances, the items are delivered to a tilt tray sortation system. Prior to induction, an overhead scanner reads a barcode on a picking label. Once the item is inducted into the tilt tray sortation system, it is dropped to an assigned packing chute where all the items for that order will be packed. Although the units for an individual order may come from several picking areas, one packer will organize that order.
Pack and ship: Each packing station is served by three chutes. A packer scans a barcode for an order as well as a pick label that accompanies the items in the chute. Once all of the units for an order have been scanned, the packer scans a bar code label to end the order. At that point, the system prints a shipping label for the carton and if necessary a carton content label. Once the shipping labels have been applied to a shipping carton or mailing pouch, they are placed one a takeaway conveyor. After they are weighed on an inline scale, an overhead scanner reads a ship via barcode and a divert code on a shipping label. Once the system knows how the package is going to be shipped, a pop-up diverter on the shipping sorter sends it to another conveyor that will deliver it to the right shipping area for carton or parcel shipping.
Sustainable distribution at Patagonia
Patagonia incorporated energy efficient materials handling and recycled building materials into the design of a 171,000 square foot addition to its Reno distribution center.
