Abstract

The invention relates to a method for weighing pharmaceutical containers (10) nested in a carrier (11), in which at least one of the nested containers (10) is weighed by means of a weighing device (1), wherein a relative movement between the at least one pharmaceutical container (10) and the carrier (11) is brought about in order to release the pharmaceutical containers (10) from the carrier (11) in order to increase the weighing accuracy.

First claim

What is claimed is:

1. A method for weighing pharmaceutical containers ( 10 ) nested in a carrier ( 11 ),
in which method at least one of the nested pharmaceutical containers ( 10 ) is weighed by a weighing device ( 1 ),
wherein a relative movement is brought about between the at least one pharmaceutical container ( 10 ) and the carrier ( 11 ) so as to release the at least one pharmaceutical container ( 10 ) from the carrier ( 11 ) in order to increase the weighing accuracy,
wherein the relative movement is brought about by an oscillation.

2. The method according to claim 1 , wherein the relative movement is brought about by a harmonic oscillation.

3. The method according to claim 1 , wherein the oscillation takes place in an x direction (x) and/or in a y direction (y) and/or in a z direction (z).

4. The method according to claim 1 , wherein the carrier ( 11 ) and/or the weighing device ( 1 ) executes the oscillation in the form of a movement.

5. The method according to claim 4 , wherein the movement of the carrier ( 11 ) and/or of the weighing device ( 1 ) is brought about by at least one servomotor ( 5 ) and/or by at least one vibration motor ( 6 ).

6. The method according to claim 1 , wherein the oscillation is introduced in the form of sound.

7. A method for weighing pharmaceutical containers ( 10 ) nested in a carrier ( 11 ),
in which method at least one of the nested pharmaceutical containers ( 10 ) is weighed by a weighing device ( 1 ),
wherein a relative movement is brought about between the at least one pharmaceutical container ( 10 ) and the carrier ( 11 ) so as to release the at least one pharmaceutical container ( 10 ) from the carrier ( 11 ) in order to increase the weighing accuracy,
wherein the relative movement is brought about by an air flow on the at least one pharmaceutical container ( 10 ).

8. A method for weighing pharmaceutical containers ( 10 ) nested in a carrier ( 11 ),
in which method at least one of the nested pharmaceutical containers ( 10 ) is weighed by a weighing device ( 1 ),
wherein a relative movement is brought about between the at least one pharmaceutical container ( 10 ) and the carrier ( 11 ) so as to release the at least one pharmaceutical container ( 10 ) from the carrier ( 11 ) in order to increase the weighing accuracy,
wherein the relative movement is brought about by electrostatic effects ( 9 ) on the at least one pharmaceutical container ( 10 ).

9. The method according to claim 1 , wherein the relative movement is brought about before weighing and/or during weighing.

10. The method according to claim 1 , wherein the at least one pharmaceutical container ( 10 ) is weighed by being lifted by the weighing device ( 1 ).

11. A processing machine ( 100 ) for processing the pharmaceutical containers ( 10 ), the processing machine ( 100 ) comprising a weighing apparatus ( 1 ), wherein the processing machine ( 100 ) is designed to execute the method according to claim 1 .

12. The method according to claim 5 , wherein the at least one servomotor ( 5 ) comprises an eccentric ( 51 ).

13. The method according to claim 6 , wherein the sound is introduced by at least one loudspeaker apparatus ( 7 ).

14. The method according to claim 7 , wherein the air flow is a pulsating air flow ( 80 ).

15. The method according to claim 7 , wherein the air flow is generated by at least one fan apparatus ( 8 ).

16. The method according to claim 7 , wherein the relative movement is brought about before weighing and/or during weighing.

17. The method according to claim 7 , wherein the at least one pharmaceutical container ( 10 ) is weighed by being lifted by the weighing device ( 1 ).

18. The method according to claim 8 , wherein the relative movement is brought about before weighing and/or during weighing.

19. The method according to claim 8 , wherein the at least one pharmaceutical container ( 10 ) is weighed by being lifted by the weighing device ( 1 ).
