Automated materials storage system and method
First Claim
1. A method of automatically addressing and handling goods in a high-rise storage system utilizing an electronically controlled storage and retrieval (S/R) machine, a central processing unit (CPU), a storage operator station and a storage aisle console, comprising the steps of:
- establishing in the CPU memory a part number file of all goods acceptable for storage;
establishing in the CPU memory a storage inventory file of all goods actually stored in the high-rise storage system;
establishing in the CPU memory a transaction file of all goods in transit to or from the high-rise storage system;
providing a plurality of transaction code numbers which can only be associated with a load of goods at the storage operator station;
examining the load of goods to be stored and entering a description of the goods into the CPU at the storage operator station;
verifying the descriptive information entered into the CPU by electronically comparing the descriptive information with the part number file of acceptable goods to determine if the description of the goods is found in the part number file;
electronically associating a transaction code number with the description of the load only if the description is found in the part number file and thereafter electronically storing the description in the transaction file at an address identifiable by the transaction code number;
physically associating the transaction code number with the load in a machine-readable form so as to eliminate further human interpretation of the goods to the CPU;
printing an identification label bearing the descriptive information and associating the printed label with the load of goods;
removing the labeled goods to a pick up station of the high-rise storage system;
reading the transaction code number into the aisle console so as to identify the description of the goods to the CPU without human interpretation thereof; and
transferring the goods to the S/R machine from the pickup station and storing the goods in a CPU-selected location.

Abstract
A system and method for automatically storing and retrieving loads of materials from a high-rise storage warehouse including providing for electronic identification of materials at a remote storage operator station and thereafter activating a CPU to (a) electronically verify the acceptability of the materials, (b) assign a transaction code to the data bit representation of the identification of the load, and (c) select an address in the high-rise storage warehouse for the load. The load is accompanied by the transaction code in machine-readable form and then moved to a pickup station adjacent the high-rise storage warehouse. Proper alignment of the load is then electronically verified and the transaction code is communicated to the CPU to identify which materials are on the pickup station. A storage-retrieval (S/R) machine is dispatched at the command of the CPU to move the load to its CPU-assigned address in the high-rise storage warehouse. In retrieving the goods, a request is entered at the storage operator station and the CPU scans all inventory to identify materials which will match the request. Then the CPU identifies the address in the high-rise storage warehouse of the requested materials and dispatches the S/R machine to retrieve the materials and place the load upon the pickup station.
As soon as a lift truck is available to remove the load, the CPU is asked for a move-ticket which is then printed in man-readable form by the CPU, the move-ticket identifying the pickup and deposit station where the load is located and such other information as may be desirable. When the load is taken from the pickup and deposit station, the load description is deleted from CPU memory automatically.

11. A method of automatically handling goods stored in high-rise storage utilizing a storage-retrieval (S/R) machine, a central processing unit (CPU), a storage operator station remote from the high-rise storage and a storage aisle console near a pickup station of the high-rise storage comprising the steps of:
-
compiling a part number file of acceptable inventory codes and electronically storing the file in the CPU memory; establishing a transaction file in the CPU memory for all goods in transit to or from the high-rise storage; compiling a storage inventory file in the CPU memory of all goods actually stored in the high-rise storage; inspecting goods to be stored and entering into the CPU at the storage operator station an identification code representing the identification of the goods; accompanying each identification code at the storage operator station with a transaction code; electronically comparing the idenntification code with the part number file of acceptable inventory codes and associating the transaction code with the identification code only when the CPU finds an inventory code which corresponds to the entered identification code; generating a label for the goods to be stored and associating the label with the goods, the label bearing the transaction code; placing the goods at a pickup station of the high-rise storage; communicating the transaction code of the goods through the storage aisle console to the CPU; automatically directing the S/R machine to remove the goods to the CPU-assigned address; entering the description of the goods from the transaction file into the storage inventory file after the goods are stored; requesting retrieval of the goods from storage by entering a descriptive code for the goods into the CPU at the storage operator station; electronically searching the inventory files until goods in storage matching the identification code of the requested goods is found; storing the identification code in the transaction file; directing an electronic command from the CPU to the S/R machine so as to transfer the S/R machine to the address of the goods corresponding to the identification code; retrieving the goods and depositing the goods at a pickup station; printing a label with information comprising at least part of the identification code for the retrieved goods and associating the label with the goods at the pickup station; and removing the goods from the pickup station.

12. A materials handling system comprising:
-
an array of bays facing onto an aisle, each bay adapted to receive a load of goods; a storage-retrieval (S/R) machine displaceable along the aisle adjacent the array of bays; a central processing unit (CPU) comprising a storage inventory file of all goods actually stored in the bays, a part number file of all goods acceptable for storage, and a transaction file of all goods in transit to or from the bay; a storage operator station for electronically processing all incoming or outgoing goods, said storage operator station comprising; a terminal electrically connected to the CPU for transmitting a description of the goods to the CPU so as to enable the CPU to verify the goods from the part number file and thereafter store said description in the transaction file at an address indentifiable by a transaction code number, said terminal also comprising means for electronically associating the transaction code number with the description of the goods; and means for physically associating the transaction code number in machine-readable form with the load of goods so as to thereafter eliminate the need for further manually programming the description of the goods into the CPU; at least one pickup and deposit station situated near the aisle so as to make the pickup and deposit station accessible by the S/R machine; and a storage aisle console electrically connected to the CPU and the S/R machine for directing the S/R machine in response to commands from the CPU so as to cause the S/R machine to remove the goods from the pickup and deposit station and thereafter store them in a selected bay only after the machine-readable transaction number has been entered into the storage aisle console so as to identify the description of the goods at the pickup and deposit station to the CPU. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20)
