Abstract

An apparatus and method for tracking inventory for goods having a variety of styles and characteristics, and which have a variety of possible shipping destinations. The apparatus of the invention includes a multi-part label that is attachable to each of the goods and has a removable portion that can be detached from the original label and reapplied to a shipping carton for a collection of goods. The method of the invention includes utilizing information from indicia applied to each of the goods in conjunction with an inventory distribution system and shipping cartons to keep track of the location of all goods at any time between sorting the goods for shipping and packing the goods for shipment, without requiring any manual steps, such as scanning, during sorting and packing of the goods.

Claims

1. A system to track inventory of a plurality of items comprising:

a label on each item, each label containing indicia which includes identifying information regarding the item wherein the label includes a base portion affixed to the item and containing the identifying information for the item and a removable portion containing identifying information for the item;

an induction reader comprising a component configured to read and store the indicia and interpret the identifying information;

a conveyor having a conveying path on which the plurality of items are transported in a known order;

multiple loading lanes, each having a known position relative to the known order of the items on the conveyor;

an unloading device operatively associated with the conveyor configured to direct, from the conveyor into a respective selected one of the loading lanes each of the items being transported by the conveyor;

multiple shipping containers capable of containing a plurality of the items and having an external surface, each shipping container associated with a selected one of the loading lanes;

a control device operatively connected to the reader and the conveyor and configured to obtain the identifying information of each of the items being transported, correlate the location of each of the items being transported on the conveyor relative to a selected one of the shipping containers, operate the unloading device such that the items are directed from the conveyor into the lanes, and correlate the location and content in the lanes of the items transported thereto by the conveyor;

so that items for the same shipping destination are placed in the same lane to form a sequence of items having a last item, and, as the items in a lane are packed into a shipping container, so the removable portion of the label of the last packed item can be placed on the external surface of the shipping container to indicate the items packed in the shipping container.

2. The system of claim 1 wherein each of the items comprises a box in which goods are placed.

3. The system of claim 2 wherein the goods are at least one pair of shoes, each pair having a style and size.

4. The system of claim 3 wherein the indicia includes information regarding style and size of the at least one pair of shoes.

5. The system of claim 1 wherein the indicia, at least in part, comprises a bar code.

6. The system of claim 5 wherein the reader comprises a bar code scanner.

7. The system of claim 1 wherein the location of an item in the known order includes information regarding the contents of that item.

8. The system of claim 1 wherein each shipping container is arranged to contain a group of the items intended for the same shipping destination.

9. The system of claim 1 wherein the items are packed in a respective shipping container in the order received in the loading lane.

10. The system of claim 1 wherein the removable portion of the label is structured to be removed from the last item packed in the respective shipping container and applied to the exterior surface of that shipping container.

11. The system of claim 1 wherein each of the labels is applied around a corner of the respective item in a manner that an end of the removable portion of the label is positioned at or near the corner and can be gripped and separated from the remainder of the label.

12. The system of claim 1 wherein the reader is positioned upstream from the loading lanes.

13. The system of claim 1 further comprising a case label, one placed onto each of the shipping containers and bearing machine-readable shipping destination information, and a downstream reader placed downstream of the loading lanes in an orientation configured to read the case label and the respective removable portion of the label applied to the container.

14. The system of claim 13 wherein the control device includes a component configured to merge information from the case label and the removable portion of the label applied to the container into a record that can be electronically stored.

15. The system according to claim 1, wherein:

the control device is operatively connected to the reader, the conveyor and the unloading device and structured such that the items placed in the same lane to form a sequence of items are transferred in a predetermined order.

16. The system according to claim 15, wherein the control device and conveyor are structured such that the items being transported to the loading lanes are arranged in a predetermined order.

17. The system according to claim 15, wherein the control device, the conveyor, and the reader are structured such that the location relative to a selected one of the loading lanes of each item being transported by the conveyor is determined.

18. The system according to claim 15, wherein the control device and the reader are structured such that the identity of the items transferred to each of the loading lanes is determined.

19. The system according to claim 15, wherein the indicia of the label of the last item transferred to a selected loading lane, to thereby complete the assembly of the, sequence of items on that loading lane effectively identifies each of the items comprising the respective sequence of items.

20. The system according to claim 15, wherein each of the items of the plurality of items comprises a box containing goods.

21. The system according to claim 15, wherein each of the items of the plurality of items comprises a box containing a pair of shoes.

22. The system according to claim 21, wherein the indicia includes information related to the style of the pair of shoes.

23. The system according to claim 21, wherein the indicia includes information related to the size of the pair of shoes.

24. The system according to claim 21, wherein the control device and the conveyor are structured such that the items being transported by the conveyor to the loading lanes are arranged in a predetermined order related to the style and size of the pairs of shoes contained therein.

25. The system according to claim 15, wherein the indicia comprises, at least in part, a bar code.

26. The system according to claim 15, wherein the indicia includes the base portion of the label on each item having first indicia and the removable portion of the label on each item having second indicia wherein the first and second indicia comprise bar code that, at least in part, contains identical information.

27. The system according to claim 15, wherein the reader includes a bar code scanner.

28. The system according to claim 15, further comprising:

a plurality of case labels, each attached to a respective one of the multiple shipping containers and containing destination indicia;

the conveyor further including a downstream conveyor portion structured to transport the multiple shipping containers away from the multiple loading lanes; and

the reader further including a downstream component configured to read the destination indicia of the respective case labels of, and the indicia of the respective removable portions secured to, the multiple containers being transported by the downstream conveyor portion.

29. The system according to claim 28, wherein the control device is further structured to merge and store information obtained by the downstream component from corresponding ones of the destination and indicia of the respective removable portion secured to the respective shipping container.
