System for delivery
First Claim
1. A method of operating a storage system, the system including a plurality of operational stations connected by a conveyor network for conveying containers between the operational stations, a first operational station comprising a storage structure having a multiplicity of container racks for holding storage containers, means for rotating the container racks about a continuous track, and means for inserting containers into and for retrieving containers from the storage structure, a second operational station comprising a work center having a work area for selectively adding materials to, withdrawing materials from or working materials within said containers, the method comprising the steps of:
- establishing a container list indicative of a plurality of containers expected to be required by the work center;
periodically updating the container list;
designating a number of containers desired in the work center;
extracting the desired number of containers from the storage structure while the container racks are in continuous motion about the track, the containers selected for extraction each being listed on the container list and chosen dependent in part on the expected efficiency of extraction from the storage structure;
delivering the selected containers to the work center; and
periodically repeating the designation, extraction and delivery steps.

Abstract
An integrated warehousing system for storing and retrieving goods as well as preparing the goods for their ultimate disposition is disclosed. The warehousing system includes numerous modular components that may be added to or subtracted from the system to accommodate a particular warehousing need. Inventoried goods placed in containers are stored on a rotational storage carousel. A plurality of work stations, each having an associated temporary storage queues are integrated with the carousel to facilitate high volume handling operations. Containers, delivered from the storage carousel, are brought to the temporary queue where they are held until an operator is prepared to work with the goods stored therein. The container is then delivered to a work area, where the operator performs the desired task. The containers, may then be delivered either to another appropriate work station or back to the storage carousel.

3. A method of operating a storage system, the system including a plurality of operational stations connected by a conveyor network for conveying containers between the operational stations, a first operational station comprising a storage structure having a multiplicity of container racks for holding the containers, means for rotating the container racks about a continuous track, and means for inserting containers into and for retrieving containers from the storage structure, a second operational station comprising a work center having a work area for selectively adding goods to, withdrawing goods from or working goods within said containers, and a vertical storage queue for holding a plurality of containers in a region adjacent the work area, each said container having at least one compartment therein and an identifying indicia thereon, the method comprising the steps of:
-
placing goods to be stored into the container compartments without arranging the goods according to ownership or kind, only one type of goods being placed in each compartment; recording the identity of the goods placed in each said container compartment and maintaining an inventory record of the contents of each container; inserting the loaded containers onto container racks of the storage structure while the container racks are in continuous motion about the track; receiving an order for a particular good stored within a warehousing system and checking the inventory record to identify a selected one of said containers that carries an ordered good; automatically extracting the selected container from the storage structure while the container racks are in continuous motion about the track and delivering the selected container to the work center. - View Dependent Claims (4, 5, 6)

7. A method of storing, retrieving and distributing inventoried materials within a system having a master controller, a storage structure with a multiplicity of racks or shelves for holding containers that carry the inventoried materials, the storage structure having means for rotating the container racks about a continuous track, the containers each having an identifying indicia associated therewith, and a plurality of work centers for selectively adding materials to, withdrawing materials from or working materials within the containers, each said work center including a work center controller for coordinating activities of its associated work center, the method comprising the steps of:
-
placing materials into said containers; establishing an inventory record indicating an identity and quantity of the specific materials placed in each said container; randomly loading the containers onto the storage structure while the container racks are in continuous motion and recording the rack where each loaded container is positioned on the storage structure; inputting orders for various materials into a master controller and checking the inventory record to determine whether each ordered material is within the system'"'"'s inventory; identifying an associated container for each ordered material within the system'"'"'s inventory, each associated container holding the associated ordered material; arranging the orders into a plurality of batches, each said batch including a plurality of orders; sending a batch of orders to a particular work center controller together with the identities of the associated containers for the materials ordered in the batch; and delivering the containers associated with the batch to the work center to which the batch was sent, wherein each said work center controller is responsible for requesting the containers associated with the materials ordered in the batch as needed by its associated work center. - View Dependent Claims (8)

9. A method of storing, retrieving and distributing inventoried goods comprising the steps of:
-
loading material goods into containers having identifying indicia; automatically placing the loaded containers onto a rotating storage carousel while the storage carousel remains in continuous motion; inputting a plurality of orders for various inventoried goods into a control means that selects containers carrying the ordered goods; automatically extracting at least some of the selected containers from the storage carousel while the storage carousel remains in continuous motion and delivering the extracted containers to a work station; automatically placing the received containers received by said work station in a randomly accessible temporary storage queue; selectively automatically moving containers from said temporary storage queue to a work area; picking desired goods from the containers while they are disposed in the work area; placing the picked goods into an article receiving means disposed on a rotational consolidation queue, wherein each said article receiving means is associated with a particular order; automatically presenting said article receiving means; whereby movements of the consolidation queue are automatically coordinated with the delivery of containers to the work area such that the article receiving means are automatically presented when a container carrying goods requested in an order appears in the work area. - View Dependent Claims (10, 11)
