Abstract

An automated process for manufacturing smart labels having a radio frequency identification transponder (RFID) transponder. The inventive method accurately and reliably inserts RFID transponders into labels on onto tags 70 in one pass on a label press 100 equipped with an in-line insertion station 120. The transponders may be provided in continuous supply reel and singulated as needed to form discrete terms transponders or single transponders may be provided in the hopper. The label is delaminated and the transponders are individually applied directly to the adhesive side of the labels in the machine direction of the moving web. The label liner is then relaminated back onto the label face stock sandwiching the RFID transponder between the liner and the label stock.

Claims

1. A method for manufacturing RFID labels comprising the steps of:

obtaining a roll of media on an unwind station of an insertion press, said press comprising the unwind station, an insertion station, a die cutting station, and a rewind station;

threading the media through at least some of the stations of the press;

transporting the media to the insertion station;

joining an RFID transponder to a second side of the media at the inseration station;

transporting the media and RFID transponder to the die cutting station;

die cutting the media at the die cutting station;

transporting the die cut media to a rewind station;

rewinding or fan folding the media at the rewind station.

2. The method of claim 1 further comprising the steps of:

transporting the media to a print station before the insertion station; and

printing the media at the print station.

3. The method of claim 1 further comprising the step of verifying the RFID transponder at least once prior to rewinding or fan folding the media.

4. The method of claim 1 wherein the media a label stock comprising a label face sheet having adhesive on the second side and a release liner further comprising the steps of:

transporting the label stock to a delamination station prior to transporting the media to the insertion station;

separating the label face stock and adhesive from the release liner at the delamination station;

transporting the label face sheet and RFID transponder to a relamination station prior to the die cutting station; and

relaminating the release liner to the label face sheet.

5. The method of claim 4 further comprising the steps of:

transporting the media to a print station before the insertion station; and

printing the media at the print station.

6. The method of claim 4 further comprising the step of verifying the RFID transponder at least once prior to rewinding or fan folding the media.

7. The method of claim 4 further comprising the step of:

applying an adhesive patch to the RFID transponder or the release liner prior to relaminating the release liner and the label face sheet.

8. The method of claim 1 wherein the media comprises tag stock further comprising the step of applying an adhesive patch to the RFID tag or the second side of the tag stock before joining the RFID transponder to the media.

9. The method of claim 8 further comprising the steps of:

transporting the media to a print station before the insertion station; and

printing the media at the print station.

10. The method of claim 8 further comprising the step of verifying the RFID transponder at least once prior to rewinding or fan folding the media.

11. The method of claim 8 further comprising the steps of:

unwinding an overlaminate media; and

applying the overlaminate media to the tag and RFID transponder prior to transporting the media to the die cutting station.

12. The method of claim 1 wherein the RFID transponders are carried on a first reel of RFID transponders further comprising the step of:

splicing a second reel of RFID transponders to the first reel of RFID transponders without bringing the press offline.

13. The method of claim 1 further comprising the steps of:

maintaining the media web in registration with the RFID transponder web.

14. The method of claim 4 further comprising the steps of maintaining the label face sheet in registration with the RFID transponder web and the release liner.

15. The method of claim 1 further comprising the step of:

sensing the location of the RFID transponder before die cutting the media.

16. A insertion press for automatically joining RFID transponders to a media web comprising:

an unwind station;

a delamination station;

an insertion station,

a relamination station;

a die cutting station,

a rewind station; and

at least one verifier.

17. The insertion press of claim 16 further comprising at least one print station.

18. The insertion press of claim 16 wherein the insertion station comprises:

an RFID transponder feed unit to supply single RFID transponders at a determined rate to a vacuum cylinder;

the vacuum cylinder having a plurality of apertures in a suction area and a non-stick area; and

a soft impression roller positioned beneath the vacuum cylinder to sandwich a media web between the vacuum cylinder and the soft impression roller.

19. The insertion press of claim 16 wherein the RFID transponder supply comprises a spindle supported at least one end, said spindle supports a reel of RFID transponders,

a channel roller feed to transport a transponder web;

and

a RFID sensor.

20. The insertion press of claim 18 wherein the insertion station further comprises an adhesive applicator.
