Storage and retrieval system case unit detection
First Claim
1. An automated storage and retrieval system for cases in a case storage room, the automated storage and retrieval system comprising:
- a storage structure with storage racks configured to support case units;
a controller, where each case unit has a predetermined storage position in which a case unit is seated on the storage racks and the controller is configured to determine the predetermined storage position;
a picking aisle configured to provide access to the case units within the storage structure; and
an automated case mapper configured to traverse the picking aisle, the automated case mapper being configured to identify a seated position of at least one case unit within the storage structure;
wherein the controller is further configured tocompare an identified seated position of the at least one case unit received from the case mapper with the predetermined storage position of the at least one case unit and identify a variance between the identified seated position and the predetermined storage position of the at least one case unit, andgenerate a command with information for case unit position correction based on a variance type, where the controller is configured to generate different case unit position correction commands corresponding to different variance types.

Abstract
An automated storage and retrieval system including a storage structure with storage racks having a seating surface configured to support case units where a position of each case unit is non-deterministic for each storage location on the storage racks, each case unit has a predetermined storage position and a controller is configured to determine the predetermined storage position, a picking aisle configured to provide access to the case units within the storage structure, and a seismic disturbance restorative system including seismic disturbance motions sensors disposed on the storage racks, a seismic disturbance control module in communication with the seismic disturbance sensors and configured to identify a seismic disturbance, and an automated case mapper configured to traverse the picking aisle, the automated case mapper being in communication with and initialized by the seismic disturbance control module to identify a seated position of at least one case unit within the storage structure.

12. A warehouse automated storage and retrieval system for transport and storage of cases of wares in a ware case storage room, the warehouse automated storage and retrieval system comprising:
-
a storage structure with an array of storage locations distributed on at least one storage shelf having a seating surface configured to support ware case units where a position of each ware case unit is non-deterministic for each storage location on the at least one storage shelf; a controller, where each ware case unit has a predetermined storage position in which a ware case unit is seated on the at least one storage shelf and the controller is configured to determine the predetermined storage position, where the controller is configured to generate different ware case unit position correction commands corresponding to different variance types; and a disturbance restorative system including at least one disturbance detection sensor disposed on the at least one storage shelf, a disturbance control module in communication with the at least one disturbance detection sensor and configured to identify a disturbance, and wherein the disturbance restorative system is configured so that the disturbance restorative system initializes a case mapper of the disturbance restorative system in response to the disturbance control module, wherein an automated guided vehicle within the storage structure traverses the storage structure relative to the at least one storage shelf to identify a ware case unit seated position type of at least one ware case unit within the storage structure from different ware case unit seated position types. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24)

25. A method for automated storage and retrieval of cases in a case storage room within an automated storage and retrieval system, the method comprising:
-
providing a storage structure with storage racks configured to support case units; determining, with a controller, a predetermined storage position for each case unit, where each case unit is seated on the storage racks in the respective predetermined storage position; providing a picking aisle configured to provide access to the case units within the storage structure; traversing, with an automated case mapper, the picking aisle, and identifying a seated position of at least one case unit within the storage structure; comparing, with the controller, an identified seated position of the at least one case unit received from the case mapper with the predetermined storage position of the at least one case unit and identifying a variance between the identified seated position and the predetermined storage position of the at least one case unit; and generating, with the controller, a command with information for case unit position correction based on a variance type, where the controller is configured to generate different case unit position correction commands corresponding to different variance types. - View Dependent Claims (26, 27, 28, 29, 30, 31, 32, 33, 34, 35)
