Abstract

A method for packaging discrete medicaments in pouches in a packaging device includes transporting the elongated web along a web trajectory, printing information on the elongated web related, feeding the discrete medicaments to the elongated web, 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.

First claim

The invention claimed is:

1. Method for packaging discrete medicaments in pouches in a packaging device,
wherein the packaging device is configured to form and fill the pouches in an elongated web to contain the medicaments,
wherein the packaging device comprises a web drive for transport of the elongated web in a transport direction over a web trajectory, and along the web trajectory in the transport direction a printing station and a filling station, wherein the printing station comprises a printer for printing information on the elongated web, and wherein the filling station is configured to feed the discrete medicaments to the elongated web,
wherein the method comprises the following steps:
transporting the elongated web along the web trajectory in the transport direction by means of the web drive whereby the elongated web passes the printing station and the filling station,
printing information on the elongated web by means of the printer, wherein the printed information on the elongated web is related to the discrete medicaments that are subsequently fed to the elongated web at the position of the printed information on the elongated web, and
feeding the discrete medicaments to the elongated web at the filling station at the position of the related printed information,
wherein a minimal order size of pouches is set, wherein for an order having a first amount of pouches to be filled with discrete medicaments that is lower than the minimal order size, for the pouches to be filled the information is printed that is related to the discrete medicaments that is subsequently fed to the elongated web at the position of the printed information on the elongated web, followed by a second amount of empty pouches in the elongated web, wherein the sum of the first amount and the second amount are equal to the minimal order size.

2. Method according to claim 1 , wherein the printer prints information on the empty pouches that is related to the empty status of the empty pouches.

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

4. The method according to claim 1 , and further comprising applying a separation perforation line in the elongated web between pouches to be formed, extending from a bottom edge over more than half of a distance between the bottom edge and a top edge of a pouch to be formed thereby forming foil bridges between the separation perforation line and the top edge.

5. The method according to claim 1 and further comprising forming a tear notch in the pouches to be formed.

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

7. The method according to claim 6 , 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.

8. The method according to claim 7 , wherein the foil comprises a printable plastic.

9. 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 .

10. Packaging device for packaging discrete medicaments in pouches, wherein the packaging device is configured to form and fill the pouches in an elongated web to contain the medicaments,
wherein the packaging device comprises a web drive for transport of the elongated web in a transport direction over a web trajectory, and along the web trajectory in the transport direction a printing station and a filling station, wherein the printing station comprises a printer for printing information on the elongated web, and wherein the filling station is configured to feed the discrete medicaments to the elongated web,
wherein the packaging device further comprises an electronic controller for controlling the packaging device, wherein the electronic controller comprises a processor and a non-transitory computer-readable medium holding instructions that, when executed by the processor, cause the packaging device to package discrete medicaments in pouches in accordance with the steps of the method according to claim 1 .

11. The packaging device according to claim 10 , and further comprising a sealing station for sealing the pouches in the elongated web.

12. The packaging device according to claim 11 , wherein the sealing station comprises two L-shaped heat seal stamps that are moveable or driven transverse to the elongated web and in a symmetric manner by means of a stamp drive to form a top heat seal and a back heat seal of one pouch, and to form a front heat seal of a following pouch.

13. The packaging device according to claim 10 , 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.

14. The packaging device according to claim 13 , wherein the perforation station comprises two perforation mechanisms that are moveable or driven transverse to the elongated web and in a symmetric manner by means of an anvil drive to form a separation perforation line and a tear notch between two pouches.

15. The packaging device according to claim 10 , wherein the electronic controller is programmed to respond to errors originating from a feeder device configured to supply a selection of discrete medicaments to the packaging device.

16. The packaging device according to claim 10 , further comprising comprises a transport monitoring device for monitoring the transport of the elongated web along the web trajectory for the inspecting the elongated web to determine whether there is a fault related to an alignment of the elongated web.

17. The packaging device according to claim 16 , wherein the transport monitoring device comprises an encoder.

18. The packaging device according to claim 10 , further comprising an inspection station along the web trajectory for inspecting the elongated web to determine whether there is a fault related to the elongated web, 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 ultrasonic inspection sensor.

19. The packaging device according to claim 18 , wherein the electronic controller is programmed to detect faults in the formed pouches by means of the inspection station.

20. The packaging device according to claim 19 , wherein a human operator that manually handles the pouches is visually warned that a human intervention is needed for disposing off the formed pouches in which faults were detected.

21. The packaging device according to claim 19 , wherein information of the fault is stored in the non-transitory computer-readable medium of the electronic controller and/or presented to a robotic operator to indicate which pouches are affected.
