Device and methods for packaging medicaments with fault detection

1. A method for packaging discrete medicaments in pouches in a packaging device configured to form and fill the pouches in an elongated web,

the method comprising the following steps:

transporting the elongated web along a web trajectory,

printing information on the elongated web related to the discrete medicaments that are fed to the elongated web at the position of the printed information on the elongated web,

feeding the discrete medicaments to the elongated web at the position on the elongated web of the related printed information,

inspecting the elongated web to determine whether there is a fault related to the elongated web, and

in response to a fault being detected, printing a fault indication or a fault symbol on the elongated web, and forming an empty pouch at the position of the fault indication or fault symbol.

2. The method of claim 1 , wherein the fault is a faulty pouch, and the printing of the fault indication or a fault symbol on the elongated web is performed upstream from the detected faulty pouch.

3. The method of claim 1 , wherein the transporting of the elongated web along the web trajectory is done by means of a web drive.

4. The method of claim 1 , wherein the printing information on the elongated web is done by means of a printer at a print station.

5. The method of claim 1 , wherein the packaging device comprises a transport monitoring device for monitoring the transport of the elongated web along the web trajectory for the step of inspecting the elongated web to determine whether there is a fault related to an alignment of the elongated web.

6. The method of claim 1 , wherein the packaging device comprises an inspection station along the web trajectory for the step of inspecting the elongated web to determine whether there is a fault related to the elongated web.

7. The method of claim 6 , wherein the inspection station comprises one or more of an inspection camera, an inspection sensor, an inspection photo sensor, an inspection laser photo sensor, or an ultrasonic inspection sensor, and the inspecting comprises an inspection of the elongated web by said inspection camera, inspection sensor, inspection photo sensor, inspection laser photo sensor or an ultrasonic inspection sensor.

8. The method according to claim 1 , and further comprising applying a heat sealing in the elongated web to enclose the medicaments that have been fed to the elongated web.

9. The method of claim 8 , wherein the step of inspecting the elongated web to determine whether there is a fault related to the elongated web comprises sensing a faulty heat sealing.

10. The method of claim 1 , and further comprising applying a separation perforation line in the elongated web between pouches to be formed, and wherein the step of inspecting the elongated web to determine whether there is a fault related to the elongated web comprises detecting a faulty separation perforation line.

11. The method of claim 1 , and further comprising forming a tear notch, and wherein the step of inspecting the elongated web to determine whether there is a fault related to the elongated web comprises detecting a faulty tear notch.

12. The method of claim 1 , wherein the elongated web comprises a foil that forms a front side and a back side between which the medicaments are received.

13. The method of claim 12 , wherein the foil is folded back onto itself, whereby the front side continues into the back side via a fold that forms a bottom edge of the elongated web.

14. The method of claim 12 , wherein the foil comprises a printable plastic.

15. The method of claim 1 , wherein the step of printing a fault indication or a fault symbol on the elongated web comprises printing the fault indication or fault symbol on the elongated web upstream from the fault.

16. Computer program product having a non-transitory computer readable medium with instructions saved thereon that, when executed by a processor, cause a packaging device to perform the method according to claim 1 .

17. A packaging device for packaging discrete medicaments in pouches, the packaging device comprising:

a web drive for transport of the elongated web in a transport direction over a web trajectory,

a printing station for printing information on the elongated web, the information related to the discrete medicaments that are fed to the elongated web at the position of the printed information on the elongated web, and

a filling station configured to feed the discrete medicaments to the elongated web in pouches formed in the elongated web,

an inspection station for detecting a fault in the elongated web; and

a controller configured to instruct the printing station to print a fault indication on the elongated web in response to a fault being detected in the elongated web, and to instruct the packaging device to form an empty pouch at the position of the fault indication.

18. The packaging device of claim 17 , wherein the fault is one or more of: a faulty pouch, a faulty seal, a faulty separation perforation, a faulty tear notch and a misalignment of the elongated web with respect to one of the stations.

19. The packaging device of claim 17 , wherein the inspection station comprises one or more of an inspection camera, an inspection sensor, an inspection photo sensor, an inspection laser photo sensor, or an ultrasonic inspection sensor.

20. The packaging device of claim 17 , and further comprising a perforation station along the web trajectory to apply one or more separation perforation and/or tear lines in the elongated web.

21. The packaging device of claim 17 , and further comprising a sealing station for sealing the pouches in the elongated web.
