Abstract

A system and method are provided for automatically labeling an electronic price label (EPL) tag. A customer data file (CDF) includes a batch of records including a product description and corresponding record number. Labels are printed sequentially for the records contained in the CDF and are automatically applied to the EPL tags in a continuous process. The record number is printed on the tag in the form of a corresponding bar code, and the record number bar code and a serial number bar code also contained on the tag are automatically read. The CDF is updated for correlating the serial number with a respective record number. Optical scanners are provided for uncovering defects in visual displays of the tags, misapplied labels, and unreadable bar codes which are then rejected. A makeup batch of records is identified from the CDF to identify record numbers without corresponding serial numbers, with the makeup batch then being used to repeat the printing and applying steps for fully processing the first batch.

Claims

1. A method for labeling tags, each having a visual electronic display and a serial number (SN) in the form of an identification (ID) bar code comprising:

providing a customer data file (CDF) including a first batch of records each having a plurality of printing fields including product description and corresponding record number (RN);

printing sequentially on respective labels said printing fields for corresponding records, with said RN being printed in the form of an RN bar code;

applying said printed labels to respective tags;

reading both said tag SN and label RN from said ID bar code and RN bar code on said tags; and

recording in said CDF for said records said tag SN corresponding with said RN.

2. A method according to claim 1 further comprising rejecting said tags for defective displays, for misapplied printed labels, and for unreadable bar codes prior to said recording step.

3. A method according to claim 2 wherein:

said defective display tags are rejected prior to said applying step;

said misapplied label tags are rejected prior to said reading step; and

said unreadable bar code tags are rejected after said reading step.

4. A method according to claim 2 wherein said rejecting step comprises:

examining said tags for defective displays prior to said printing step, and rejecting defective display tags prior to applying said printed label thereto;

examining said printed label tags for misapplied printed labels, and rejecting misapplied printed label tags prior to said reading step; and

attempting to read both said ID bar code and said RN bar code on said applied label tags, and rejecting unreadable bar code tags.

5. A method according to claim 4 wherein said examining step optically views said tags.

6. A method according to claim 4 wherein said reading step optically reads said bar codes.

7. A method according to claim 2 further comprising:

identifying from said CDF after said first batch of records is first sequentially processed to completion through said recording step all records corresponding with said rejected tags in a makeup batch of records; and

repeating said printing and subsequent steps for said makeup batch of records corresponding with said rejected tags until said first batch is fully processed.

8. A method according to claim 7 further comprising transmitting from said CDF said printing fields sequentially for said entire first batch for said printing step prior to said CDF recording step for continuously processing said labels and tags.

9. A system for labeling tags each having a visual electronic display and a serial number (SN) in the form of an identification (ID) bar code comprising:

a programmable controller for containing a customer data file (CDF) including a first batch of records each having a plurality of printing fields including a product description and a corresponding record number (RN);

means operatively joined to said controller for sequentially printing on said labels said printing fields for corresponding records, with said RN being printed in the form of an RN bar code;

means for transporting said tags in sequence;

means for applying said printed labels to respective ones of said tags carried by said transporting means;

means for reading both said tag SN and said label RN from said ID bar code and said RN bar code on said applied label tags, said reading means being operatively joined to said controller to communicate thereto said tag SN and label RN; and

said controller being effective for recording in said CDF for said records said tag SN corresponding with said label RN.

10. A system according to claim 9 further comprising:

means for examining said tags for defective displays and misapplied labels; and

means for rejecting from said transporting means tags having defective displays, misapplied labels, and unreadable bar codes.

11. A system according to claim 10 wherein said rejecting means are effective to reject:

said defective display tags prior to transport to said label applying means;

said misapplied label tags prior to transport to said reading means; and

said unreadable bar code tags after transport past said reading means.

12. A system according to claim 10 wherein said examining means comprise:

a first optical image scanner disposed adjacent to said transporting means and upstream of said label applying means for optically examining said tag visual display; and

a second optical image scanner disposed adjacent to said transporting means and downstream of said label applying means for optically examining placement of said label on said tag.

13. A system according to claim 12 wherein said reading means comprise:

a first optical bar code scanner disposed adjacent to said transporting means for reading said RN bar code; and

a second optical bar code scanner disposed adjacent to said transporting means for reading said ID bar code.

14. A system according to claim 10 wherein said controller is further effective for:

identifying from said CDF after said first batch of records is first sequentially processed to completion through said recording step all records corresponding with said rejected tags in a makeup batch of records; and

transmitting sequentially said printing fields of said makeup batch to said printing means for printing and applying labels to additional tags for said makeup batch.

15. A system according to claim 14 wherein said controller is further effective for transmitting from said CDF to said printing means said printing fields sequentially for said entire first batch prior to recording in said CDF for continuously processing said labels and tags.
