Abstract

The present disclosure provides a device for packaging drug portions, including a plurality of reservoir and dispensing stations, at least one conveyance and collecting apparatus, a packaging material feed, a packaging device, a folding and conveyance device included with the packaging device, a guide device including a receiving segment and a conveying segment, the conveying segment extending along the passage of the folding and conveyance device and guides drug portions into the tubular packaging material web, a first joining device arranged downstream of the folding and conveyance device, and a second joining device arranged downstream of the first joining device, which joins the tubular packaging material web at pre-specified intervals with respect to the direction of movement of the tubular packaging material, such that a continuous blister tube is created.

First claim

What is claimed is:

1. A device for packaging drug portions, the device comprising:
a plurality of reservoir and dispensing stations for dispensing individual drug portions;
at least one conveyance and collecting apparatus for receiving and transferring the drug portions dispensed by the reservoir and dispensing stations;
a packaging material feed for feeding a flexible and elongated packaging material web; and
a packaging device, comprising:
a folding and conveyance device, the folding and conveyance device having a packaging material receiving area including a passage, where the elongated packaging material web is fed into the passage and is molded into a tubular packaging material web, the shape of which is defined by the passage, the passage at least partially defining a packaging material overlap region;
a guide device including a receiving segment and a conveying segment, the conveying segment extending along the passage of the folding and conveyance device and guides drug portions into the tubular packaging material web;
a first joining device arranged downstream of the folding and conveyance device for seaming the tubular packaging material web at the packaging material overlap region in a direction of movement of the tubular packaging material web, wherein the first joining device comprises two joining elements, two drive belts and two drives, wherein each joining element is actuated by a corresponding drive belt and drive; and

a second joining device arranged downstream of the first joining device, which seams the tubular packaging material web at pre-specified intervals with respect to the direction of movement of the tubular packaging material web, such that a continuous blister tube is created, wherein the second joining device includes a drive device for moving the second joining device in, and opposite to, the direction of movement of the tubular packaging material web.

2. The device for packaging drug portions according to claim 1 , further comprising a cutting element disposed within a recess of a joining element of the second joining device, the cutting element configured to move into and out of the recess.

3. The device for packaging drug portions according to claim 2 , wherein the cutting device is operatively associated with the second joining device.

4. The device for packaging drug portions according to claim 1 , wherein the second joining device seams the tubular packaging material web by welding.

5. The device for packaging drug portions according to claim 1 , wherein the folding and conveyance device narrows conically at substantially a center of the folding and conveyance device.

6. The device for packaging drug portions according to claim 1 , wherein the folding and conveyance device includes a raised conical form.

7. The device for packaging drug portions according to 6 , wherein the raised conical form includes the passage therethrough.

8. The device for packaging drug portions according to claim 1 , wherein the first joining device is arranged on a receiving plate.

9. The device for packaging drug portions according to claim 1 , wherein the second joining device comprises two joining elements and two independently movable horizontal adjusting mechanisms.

10. The device for packaging drug portions according to claim 2 , wherein the cutting element includes a plurality of cutting teeth, and the blister tube and the cutting element are movable relative to each other to sever or perforate the blister tube.

11. A method of forming a blister tube containing drug portions with a packaging device, comprising:
molding an elongated packaging material into a tubular packaging material web by a folding and conveyance device having a packaging material receiving area including a passage, where the elongated packaging material web is fed into the passage and is molded into the tubular packaging material web, the shape of which is defined by the passage, the passage at least partially defining a packaging material overlap region;
guiding drug portions into the tubular packaging material web by a guide device that includes a receiving segment and a conveying segment, the conveying segment extending along the passage of the folding and conveyance device;
seaming the tubular packaging material web at the packaging material overlap region in a direction of movement of the tubular packaging material web by a first joining device arranged downstream of the folding and conveyance device, the first joining device comprising a first joining element actuated by a first drive belt and first drive, and a second joining element actuated by a second drive belt and second drive; and
seaming the tubular packaging material web at pre-specified intervals with respect to the direction of movement of the tubular packaging material web by a second joining device arranged downstream of the first joining device, such that a continuous blister tube is created.

12. The method of claim 11 , further comprising:
moving, by a drive device of the second joining device, the second joining device in, and opposite to, the direction of movement of the tubular packaging material web.

13. The method of claim 11 , further comprising:
severing, by a cutting device with a cutting element, the blister tube at pre-specified intervals with respect to the direction of movement of the tubular packaging material.

14. The method of claim 13 , further comprising:
moving the cutting element that includes a plurality of cutting teeth to sever or perforate the blister tube.

15. The method of claim 13 , further comprising:
operatively associating the cutting device with the second joining device.

16. The method of claim 13 , further comprising:
accommodating the cutting element in a joining element of the second joining device.

17. The method of claim 11 , further comprising:
seaming, by the second joining device, the tubular packaging material web by welding.
