Abstract

Inventory management of work-in-process (WIP) inventory within a processing facility is accomplished with a staged holding area in concert with control systems. Receiving of material into the staging area is tracked by scanning mechanisms such as Radio Frequency ID (RFID) or bar coding methods. Aggregation of material is recorded by cart sizing factors into the automatic control system. Carts are stored temporarily in locations arranged in a pre-determined grid fashion. The grid location information for a cart is made known to the automatic control system for reference or reporting to production supervisors. Down-stream processing can request staged inventory material from staging operators via overhead message boards or computer screens. Requests may be by particular types of material or by specific cart grid location. Manual entry or manual release of material is also accommodated including manual corrections of staged materials. Release of entire cart contents to down-stream processing is converted to actual material counts

Claims

1. A system for managing staged material in a processing facility, the system scanning material entering and exiting the system, comprising:

an inventory database containing data structures to record the material entering and exiting a staging area of the processing facility and to record location assignment data of the material; and

a staging area controller which accesses the inventory database for tracking and managing the material entering and exiting the staging area of the processing facility,

wherein a substantially accurate inventory of staged material is maintained by the system.

2. The system according to claim 1, wherein the staging area contains a storage area which is a bulk-grid storage area.

3. The system according to claim 1, further comprising:

a material system controller which manages overall processing facility inventory;

a sorter discharge sensor for scanning and sorting the material entering the staging area;

a scanning device for scanning the material exiting the staging area; and

a network connecting the material system controller, the staging area controller, the sorter discharge sensor and the scanning device to enable communication therebetween.

4. The system of claim 3, wherein:

the sorter discharge sensor comprises one of a bar code reader and a Radio Frequency Identification reader; and

the scanning device for scanning the material exiting the staging area comprises one of a bar code reader and a Radio Frequency Identification reader.

5. The system of claim 1, further comprising:

at least one message board for displaying material requests;

a display and entry pad for entering updates to the inventory database; and

a manual receipt station for receiving the material manually into the staging area.

6. The system of claim 5, further comprising a manual dispatch station for releasing the material manually from the staging area.

7. The system of claim 1, wherein the staging area controller further manages storing of the staged material in a storage area associated with the staged area.

8. The system of claim 1, further comprising at least one hand-held scanner for scanning the material into and from the staging area.

9. The system of claim 1, further comprising at least one conveyor for discharging and inducting the material to and from the staging area, respectively.

10. The system of claim 1, further comprising a timer for monitoring the timing of the induction of the material from the staging area.

11. The system of claim 1, wherein the inventory database contains data structures reflecting material type and at least one of count and quantities of the material and location area via a bulk-grid layout structure.

12. A method for managing material entering and exiting a staging area in a processing facility and for storing the material in a storage area, the method comprising the steps of:

sorting the material by material ID as it enters the staging area;

recording the material entering and exiting the staging area in a database via the material ID;

recording location assignment data of the material in the staging area in the database; and

tracking and managing the material entering and exiting the staging area by accessing the recorded information in the database.

13. The method of claim 12, further comprising:

loading the material into at least one container;

incrementing a container counter in the database to reflect a count of the material in the container;

displaying a grid location in a storage location associated with the staging area, the grid location being displayed by a staging area controller accessing the database which contains data reflecting storage availability;

moving the at least one container to the grid location in the storage location; and

incrementing the container inventory in the database based on the moving step.

14. The method of claim 13, further comprising checking whether the container is full by comparing the container count to a limit.

15. The method for managing staged material of claim 13, further comprising the steps of:

receiving the at least one container moved to the staging area;

scanning the at least one container to record the arrival of the material into the staging area in the database.

16. The method for managing staged material of claim 13, further comprising the steps of:

displaying operational demands on a message board display which requests the material;

entering the material into automation equipment;

scanning the material entered into the automation equipment which records the exiting of the material from the staging area;

decrementing a current container counter in the database to reflect the amount of the material in the the at least one container;

checking whether the current container counter has reached a limit;

decrementing container inventory in the database to reflect a current count of the the at least one container.

17. The method for managing staged material of claim 13, further comprising the steps of:

selecting the material to be moved to an operation based on a material request on a message board;

displaying grid locations of the selected material in the storage area;

removing the at least one container from a specified grid location in the storage area which holds the selected material; and

scanning the at least one container to record the exiting of the container from the staging area.

18. The method according to claim 13, further comprising the step of requesting a report that includes information on container counts, material counts, and containers by location.

21. The method for managing staged material of claim 18, further comprising the step of performing a reconcile function when no containers of a type are in the bulk-grid storage location, the reconcile function resetting the container inventory in the database.

19. A method for managing material entering and exiting a staging area in a processing facility wherein the staged material is stored in a bulk-grid storage location, the method comprising the steps of:

displaying an operational demand on a message board display;

entering the, material onto an automation equipment conveyor;

scanning the material entered onto the automation equipment conveyor;

decrementing a current container counter in a database to reflect the count of the material in a container;

checking whether the current container counter has reached a limit;

decrementing a container inventory in the database to reflect the count of containers if the limit has been reached.

20. The method for managing staged material of claim 19, further comprising the steps of:

selecting the material to be moved to an operation based on material request on the message board;

displaying grid locations of selected the material in the bulk-storage location;

removing the container from a grid location in the bulk-storage location;

scanning a container which records in the database the exiting of the material from the staging area.
