Abstract

The invention relates to a control device ( 10 ) comprising a radiation source ( 17 ) which is embodied, in particular, as an X-ray source for irradiating a pharmaceutical product ( 1 ) embodied, in particular as a capsule, a detector ( 18 ) for detecting radiation after irradiating the pharmaceutical product ( 1 ), a tube or shaft-shaped supply device ( 15 ) which is preferably arranged vertically at least in the region of the beam path ( 16 ) of the radiation source ( 17 ) for feeding the pharmaceutical product ( 1 ) into the beam path ( 16 ) of the radiation source ( 17 ), and means ( 25 ) for positioning and releasing the pharmaceutical product ( 1 ) in the region of the radiation beam ( 16 ) of the radiation source ( 17 ). According to the invention, the tube or shaft-shaped supply device ( 15 ) has a cross-section in the region of the beam path ( 16 ) which is greater than the cross-section of the pharmaceutical product ( 1 ), and that during irradiation, respectively only one pharmaceutical product ( 1 ) is arranged in the region of the beam path ( 16 ) of the radiation source ( 17 ).

First claim

The invention claimed is:

1. A control device ( 10 ) comprising:
a radiation source ( 17 ) for irradiating a pharmaceutical product ( 1 ),
a detector ( 18 ) for detecting radiation after irradiating the pharmaceutical product ( 1 ),
a tube or shaft-shaped supply device ( 15 ) for feeding said pharmaceutical product ( 1 ) into a beam path ( 16 ) of the radiation source ( 17 ), and
a stopping flap ( 25 ) in the region of the radiation beam ( 16 ), the stopping flap ( 25 ) being pivotable or displaceable perpendicularly with respect to a direction of transportation of the pharmaceutical product ( 1 ) for positioning and releasing said pharmaceutical product ( 1 ) in the region of the beam path ( 16 ) of the radiation source ( 17 ) such that during irradiation, respectively only one pharmaceutical product ( 1 ) is arranged in the region of the beam path ( 16 ) of the radiation source ( 17 ),
wherein the tube or shaft-shaped supply device ( 15 ) has a cross-section in the region of the beam path ( 16 ) which is greater than a cross-section of said pharmaceutical product ( 1 ) and
wherein the stopping flap ( 25 ) is permeable to radiation of the radiation source ( 17 ).

2. The control device according to claim 1 characterized in that the stopping flap ( 25 ) forms a supporting surface for the pharmaceutical product ( 1 ) during irradiation.

3. The control device according to claim 2 , characterized in that the stopping flap ( 25 ) is arranged with an axis of rotation ( 26 ) thereof in a region of the supply device ( 15 ), forms a part of the supply device ( 15 ) in a release position thereof and in a stopping position thereof rests against an opposite wall of said supply device ( 15 ) or against the detector ( 18 ) with a side thereof facing away from the axis of rotation ( 26 ).

4. The control device according to claim 1 , characterized in that the supply device ( 15 ) has a rectangular cross-section at least in the region of the radiation beam ( 16 ) of the radiation source ( 17 ).

5. The control device according to claim 1 , characterized in that the radiation source ( 17 ) exposes the pharmaceutical product ( 1 ) to radiation at an oblique angle in relation to a longitudinal axis ( 30 ) thereof.

6. The control device according to claim 1 , characterized in that further stopping means ( 34 , 35 ), which are provided for blocking the pharmaceutical product ( 1 ) and interact with a good/bad removal device ( 40 ), are disposed downstream of the detector ( 18 ) of the supply device ( 15 ) in a direction of transportation of said product.

7. The control device according to claim 1 , characterized in that the pharmaceutical products ( 1 ) are fed into a region of the supply device ( 15 ) by means of a transport device embodied as a progressively rotated transport wheel ( 12 ), said transport wheel ( 12 ) having individual receptacles ( 13 ) for the pharmaceutical products ( 1 ).

8. The control device according to claim 1 , characterized in that a reference object for comparison with the pharmaceutical product ( 1 ) is arranged in a region of the detector ( 18 ).

9. The control device according to claim 1 wherein the radiation source ( 17 ) is an X-ray source.

10. The control device according to claim 1 wherein the pharmaceutical product ( 1 ) is a capsule.

11. The control device according to claim 1 wherein the tube or shaft-shaped supply device ( 15 ) is arranged vertically at least in the region of the beam path ( 16 ) of the radiation source ( 17 ).

12. The control device according to claim 1 , characterized in that a length of said stopping flap ( 25 ) is greater than a length of the pharmaceutical product ( 1 ).
