Abstract

An automated receiving station is provided for inventorying stock items. The receiving station comprises a plurality of independently driven conveyor sections arranged sequentially for moving items along a predetermined path from a deposit end to a removal end while reading bar coded labels on the items and weighing the items. Further, identification labels are affixed to those items not otherwise having labels. More specifically, the independently driven conveyor sections include a receiving conveyor section for sequentially receiving items thereon, a scanner conveyor section along which items thereon may be scanned for identifying indicia, a weighting conveyor section for weighting any of the terms positioned thereon and a labeler conveyor section for affixing identifying indicia onto any one of the items. The receiving station also includes an accumulator conveyor section adjacent the labeler conveyor section for receiving items therefrom and a delivery conveyor section where items can be picked up by a transport system or device.

scanning means positioned adjacent one of said conveyor sections for scanning an item for indicia and reading said indicia to determine identification information for said item when said item is positioned on said one of said conveyor sections;

said scanning means being in communication with computing means for automatically entering said identification is information for said item for storage in said computing means when said scanning means has read said indicia on said item, said scanning means being in communication with said control means for signalling for movement of said one of said conveyor sections and a subsequent adjacent conveyor section after said identification information has been automatically entered into said computing means; and

data entry means in communication with said computing means for manually entering said identification information for said item for storage in said computing means when said scanning means has not read said indicia on said item, said data entry means also being in communication with said control means for signalling for movement of said one of said conveyor sections and a subsequent adjacent conveyor section after said identification information been manually entered into said computing means.

2. The automated receiving station of claim 1 further comprising a timer associated with said scanning means for allowing a preset time period during which to successfully scan said item for said indicia.

3. The automated receiving station of claim 2 further comprising an alarm in communication with said scanning means for signalling when said indicia were not successfully scanned on said item within said preset time period.

4. The automated receiving station of claim 1 further comprising a receiving conveyor section adjacent said deposit end for placement of said item onto said receiving station.

5. The automated receiving station of claim 4 further comprising placement means for sensing proper placement of said item on said receiving conveyor section at said deposit end of said receiving station.

6. The automated receiving station of claim 5 wherein said placement sensing means is in communication with said control means to prevent movement of said receiving conveyor section until said item is properly placed.

7. The automated receiving station of claim 5 wherein said item comprises an elongated cylindrical paper roll and said placement sensing means senses that said roll is upright and centrally positioned.

8. The automated receiving station of claim 1 further comprising means for producing relative movement between said item positioned on said one of said conveyor sections and said scanning means.

9. The automated receiving station of claim 1 wherein said item comprises an elongated cylindrical paper roll and including mean for moving said scanning means vertically up and down relative to said elongated cylindrical paper roll as it is rotated.

10. The automated receiving station of claim 1 further comprising weighing means for obtaining weight information for said item placed thereon, said weighing means being associated with a weighing conveyor section downstream of said one of said conveyor sections where said scanning means is positioned, said weighing means being in communication with said computing means for automatically entering said weight information for said item for storage in said computing means in conjunction with said identification information for said item, said weighing means being in communication with said control means for signalling for movement of said weighing conveyor section and a subsequent adjacent conveyor section after said weight information has been automatically entered into said computing means.

11. The automated receiving station of claim 10 wherein said computing means stores said identification information for a plurality of said items in a sequential stack and stores said weight information in conjunction with the oldest of said items on said stack not having weight information associated therewith.

12. The automated receiving station of claim 10 further comprising a scale sensor in communication with said weighing means to signal said weighing means when said item is properly positioned on said weighing conveyor section to obtain said weight information for said item.

13. The automated receiving station of claim 1 further comprising a label printer for printing coded indicia and a label applicator positioned adjacent a labeler conveyor section for affixing a label onto said item, said label applicator being in communication with said control means for signalling for movement of said labeler conveyor section and a subsequent adjacent conveyor section after said label has been affixed onto said item positioned on said labeler conveyor section.

14. The automated receiving station of claim 13 wherein said label printer is in communication with said control means so as to print a label when said item does not have said indicia thereon.

15. The automated receiving station of claim 1 including a plurality of accumulator conveyor sections downstream of said one of said conveyor sections adjacent said removal end to accumulate said items.

16. The automated receiving station of claim 15 including a delivery conveyor section downstream of said accumulator conveyor sections and adjacent said removal end for removal of said items from said station.

17. The automated receiving station of claim 1 further comprising a plurality of item sensing means for sensing when one of said conveyor sections has an item positioned thereon, one of said item sensing means being associated with each of said conveyor sections, and each of said item sensing means being in communication with said control means to prohibit an item moving onto any occupied one of said conveyor sections.

18. The automated receiving station of claim 10 wherein said computing means is in communication with an accounts receivable data base for comparing said weight information for each of said items with respective invoice information.

19. An automated receiving station for sequentially inventorying a plurality of stock items, said receiving station, comprising:

a receiving conveyor section for sequentially receiving items thereon, said receiving conveyor section having driving means for moving said items placed thereon, said items being moved by said driving means in a predetermined path;

a scanner conveyor section adjacent to said receiving conveyor section and movable in synchronization therewith, said scanner conveyor section having driving means for moving any of said items placed thereon in a predetermined path;

a weighing conveyor section adjacent to said scanner conveyor section and movable in synchronization therewith, said weighing conveyor section having driving means for moving any of said items placed thereon in a predetermined path;
