Abstract

A system, method, and software are for moving inventory items to an unloading station in response to a fulfillment order. An input device is used to enter identification information about the inventory items. At a loading station, the inventory items are received and loaded into holders. The holders are then moved to storage area. A controller is configured for creating and storing a first association between the entered identification information and each of the holders in which each of the inventory items is placed. A selector and transporter are responsive to the fulfillment order and the first association, and are configured to select a holder which holds the inventory items corresponding to the fulfillment order, and configured to transport the holder from the storage area to the unloading station.

Claims

1. A fulfillment system, comprising:

an input device for entering identification information about a plurality of inventory items;

a plurality of holders, each dimensioned for receipt and holding of one of the inventory items;

at least one loading station configured for placing each of the inventory items into one of the holders;

a controller configured for creating and storing a first association between each of the entered identification information and each of the holders in which each of the inventory items is placed, wherein the first association uniquely associates each of the entered identification information with a unique identifier of each holder;

a selector and transporter, responsive to a fulfillment order and the first association, configured to select at least one of the holders holding the inventory items which correspond to the fulfillment order, and transport the at least one of the holders to at least one unloading station; and

a machine readable identifying means comprising holder information which, in combination with the entered identification information on the inventory item, enables selection of the inventory item.

2. The fulfillment system of claim 1, wherein the controller is configured to create and store a second association, between the entered identification information of each of the inventory items and one or more of the storage areas.

3. The fulfillment system of claim 1, wherein:

the controller is configured to create and store a second association between the identification information and at least one storage area;

the controller uses the first and second associations to determine whether a requested fulfillment item is located in a particular storage area of the at least one storage area; and

the controller instructs the selector and transporter to select the holder from the storage area and transport the holder to an unloading station.

4. The fulfillment system of claim 3, wherein:

the controller is configured to create and store a second association, between the entered identification information of each of the inventory items and one or more of storage areas; and

the inventory items are retrievable from one or more of the storage areas based upon the second associations.

5. The fulfillment system of claim 1, wherein the selector and transporter:

move unsorted inventory items on a first transport of the selector and transporter,

move sorted inventory items to a second transport of the selector and transporter in a specific sequence, using clamps and a clamp driving mechanism to convey the inventory items, and

wherein feeding, sorting, and unloading operations are performed separately and simultaneously with three separate batches of inventory items associated with three separate routes.

6. The fulfillment system of claim 5, wherein the clamps are oriented upside down for loading, right side up for sorting, then upside down again for unloading.

7. The fulfillment system of claim 5, wherein the clamps are initially spaced at a distance from one another, and then subsequently abutting one another during transport of the mail pieces.

20. The fulfillment system of claim 1, wherein:

the inventory items are mail pieces;

after the mail pieces have left a sorter, the controller isolates the mail pieces to anywhere within postal processes using a unique identifier and one of;

re-directs a particular mail piece to a new destination;

stops delivery of the particular mail piece; and

guarantees the delivery of the particular mail piece at a certain time on a certain day, before or after the mail piece is inducted into the postal processes.

8. A software product for directing movement of inventory items to at least one unloading station in response to a fulfillment order, the software product comprising a computer readable medium having codes therein for execution by a processor, so that when executed the codes provide for steps comprising:

entering identification information associated with a plurality of the inventory items;

receiving and holding each of the inventory items in one of a plurality of holders;

creating and storing a first association between the entered identification information of each of the inventory items and each of said holders in which each of said inventory items is placed;

storing at least one of the plurality of holders in at least one storage area; and

selecting and transporting the inventory items held by said holders, in order to move said holders from the at least one storage area to the unloading station, based at least partly upon the first association and the fulfillment order.

9. The software product of claim 8, wherein the selecting and transporting is enabled by identifying both holder information in combination with the entered identification information on the inventory item and the first association uniquely associates each of the entered identification information with a unique identifier of each of the holder.

10. The software product of claim 8, wherein when executed the codes provide for steps comprising:

feeding, sorting, and unloading operations performed separately and simultaneously with three separate batches of inventory items associated with three separate routes,

singulating the plurality of the inventory items and then capturing them by the holder which is a clamp,

opening the clamp to release the inventory items at the unloading station by using a jaw opener,

wherein clamps are oriented upside down for loading, right side up for sorting, then upside down again for unloading as they are transported, and the clamps are initially spaced at a distance from one another, and then subsequently abutting one another during transport of the mail pieces.

11. A method of sorting mail in a sorting system, comprising:

singulating mail pieces and then capturing them by a clamp;

feeding clamped mail pieces into a queue before starting a sorting step; and

processing the mail pieces from three or more different routes simultaneously, comprising;

a first route in a feeding operation;

a second route in a sorting operation; and

a third route in an unload and traying operation

wherein for all transporting, sorting, and unloading operations, the system handles and manipulates the clamp, not the mail pieces.

12. The method of claim 11, further comprising recycling empty clamps back to the feeder.

13. The method of claim 11, further comprising:

moving unsorted mail pieces on a first transport,

moving sorted mail pieces to a second transport in a specific sequence, using the clamps and a clamp driving means to convey the mail pieces; and

performing the feeding, sorting, and unloading operations separately and simultaneously with three separate batches of mail associated with three separate routes.

14. The method of claim 11, wherein the clamps are oriented upside down for loading, right side up for sorting, then upside down again for unloading.

15. The method of claim 14, wherein the clamps are initially spaced at a distance from one another, and then subsequently abutting one another during transport of the mail pieces.

16. The method of claim 11, further comprising:

entering identification information associated with each of the mail pieces;

creating and storing a first association between the entered identification information of each of the mail pieces and each clamp holding the mail pieces;

storing the clamped mail pieces in at least one storage area; and

selecting and transporting the clamped mail pieces, in order to move the clamped mail pieces from the at least one storage area to an unloading station, based at least partly upon the first association and a fulfillment order.

17. The method of claim 16, wherein the first association uniquely associates each of the entered identification information with each of the clamps.

18. The method of claim 16, wherein each clamp includes a unique identifier which, in combination with the entered identification information on the mail pieces, enables selection and movement of clamped mail pieces.

19. The method of claim 16, further comprising creating and storing a second association, between the entered identification information of each of the mail pieces and one or more of the storage areas, wherein clamped mail pieces are retrieved from one or more of the storage areas, based at least partly upon the second association.
