Abstract: An RFID enabled system and method for tracking, directing, verifying, and validating item level order picking functions within order fulfilment and warehouse facilities having different SKUs sharing an inventory tote. RFID tags are coupled to each inventory item to be read by one or more RFID reader(s) in the facility. The system and method verify that a required item is picked and transferred correctly by the picker. The system provides feedback to the picker without requiring additional verification steps and preferably without any visual inspection by the picker. The picker may be guided to the required item and later directed to a location to place the retrieved item. The verification system may be adapted for use in a material handling system to monitor and direct material handling functions based on relative positions of RFID tags on individual items relative to RFID readers positioned throughout the facility.

Abstract: A multiple temperature automated storage system includes a rack with multiple levels of shelves defining item storage positions, an aisle at each level, and a plurality of shuttles adapted to operate in the aisles for storing items to and retrieving items from the storage positions. A thermally insulated enclosure encloses some of the levels of the rack to define a low temperature zone with the remaining levels of the rack defining a higher temperature zone. A method of storing items at two different temperatures in a common automated storage system includes having a first portion of the automated storage system enclosed in a thermally insulated enclosure and a second portion of the automated storage system outside of the thermally insulated enclosure. A lift is provided in the second portion for supplying items to and retrieving items from both of the first and second portions, without entering the first portion.

Abstract: A material handling system and method of arranging articles, includes storing articles in an automated storage and retrieval system having a rack system with multiple levels, some of the multiple levels defining storage shelves and an aisle between storage shelves at the level. Articles are stored to and retrieved from the storage shelve at opposite sides of an aisle with a plurality of shuttles, each at the aisle at one of the levels. Elevation of an article is changed to one of the levels with a first of a plurality of article lifts supported by the rack system for storage by one of the shuttles. Elevation of an article that is retrieved by one of said shuttles at one of the levels is changed with the first of a plurality of article lifts. Articles are retrieved from the first of the article lifts in a first sequence of articles with a sequencer. The sequencer includes at least a second of the article lifts, a third of the article lifts, and a conveying surface supported by the rack system.

Abstract: A method and system for fulfilling orders includes establishing a queue of orders that are available to be filled, each order in the queue containing at least one unique item type. An order from the order queue is selected and opened as a first order. Another order from the order queue is selected and opened as a second order. Inventory containers each having a unique item type for at least one of the orders are delivered and an operator picks the unique item type from the inventory container. The orders are assembled at order assembly locations that are a particular distance from the operator. The orders are selected and/or the assembly locations assigned in a manner that improves order fulfillment productivity, such as by reducing order fulfillment time, reducing operator travel distance, and the like.
