Abstract

The invention relates to a device for tabletting a powdered, liquid, pasty, encapsulated or granular active ingredient composition, having a magazine which has a plurality of active ingredient containers each with an individually controllable dosing device and a nozzle for the active ingredient outlet, wherein the magazine is adjustable between a plurality of setting positions relative to at least one die chamber, wherein in each of the setting positions at least one of the nozzles faces an opening of the die chamber. A corresponding method is further described.

Claims (29)

1. A device for tabletting a powdery, liquid, pasty, encapsulated or granular active substance composition, with a magazine comprising a plurality of active substance containers each with an individually controllable dosing device and a nozzle for the active substance outlet, wherein the magazine is adjustable between a plurality of setting positions relative to at least one die chamber, wherein in each of the setting positions at least one of the nozzles faces an opening of the die chamber, wherein the magazine is a spherical magazine, and wherein the active ingredient containers extend in the radial direction of the spherical magazine and open with their respective nozzle into a spherical surface of the spherical magazine.

2. The device of claim 1 , wherein the at least one die chamber is received in a base plate having a concave recess in which the spherical magazine is received.

3. The device of claim 2 , wherein the at least one die chamber is disposed at a deepest point of the recess.

4. The device of claim 2 , wherein the spherical magazine is adjustable relative to the base plate about at least one axis extending parallel to the base plate.

5. The device according to claim 1 , in which the spherical magazine has, in its center, a cavity in which an actuating element is freely movably accommodated, the actuating element having an actuator which is adjustable between a confirmation position and a release position.

6. The device of claim 5 , wherein either the actuating element is spherical in shape and is positively received in the cavity, or wherein the actuating element is a rotatably mounted cam with its center of gravity located outside the axis of rotation, wherein the actuator is a cam projection.

7. The device of claim 5 , wherein the actuating member has a passage extending through its center in which is disposed a solenoid coil having a coil core movable along the coil axis.

8. The device of claim 7 , wherein the passageway is positioned with respect to the center of gravity of the actuating member such that the passageway is vertically oriented regardless of the orientation of the magazine.

9. The device according to claim 1 , wherein the spherical magazine comprises a linearly adjustable plunger facing the opening of the die chamber in one of the setting positions or in a further setting position of the spherical magazine relative to the die chamber.

10. The device of claim 9 , wherein the plunger has a die at a free end thereof, with the plunger in an extended position projecting into the die chamber through the opening, and with the plunger in a release position out of engagement with the die chamber.

11. The device according to claim 1 , wherein at least one of the active ingredient containers comprises processing means for an active ingredient.

12. The device of claim 11 , wherein the processing means is or comprises a heating element for heating and/or a cooling element for cooling an active ingredient.

13. The device according to claim 1 , in which the magazine has, in addition to the plurality of active substance containers, at least one carrier material container with an individually controllable dosing device and a nozzle for the carrier material outlet, wherein in a further setting position of the magazine the nozzle of the carrier material container faces an opening of the die chamber and/or a base plate of the device, which has the die of a tablet package.

14. The device of claim 13 , wherein the die comprises a plurality of the die chambers.

15. A method for tableting an active ingredient with a device according to claim 1 , comprising:

a. Prescribing an active ingredient composition to be tableted;

b. Adjusting the magazine relative to the die chamber until the magazine assumes a position in which the active substance container of the magazine faces the die chamber with its nozzle, in which an active substance of the active substance composition is stored;

c. dosing a dose of the first active ingredient predetermined by the active ingredient composition into the die chamber; and

d. optionally repeating steps b. and c. for each additional active ingredient of the active ingredient composition if the active ingredient composition comprises more than one active ingredient.

16. The method of claim 15 , further comprising:

e. Moving the magazine relative to the die chamber until the magazine assumes a position in which a binder reservoir of the magazine faces the die chamber with its nozzle, in which a binder is stored;

f. Dosing a dose of the binder predetermined by the active ingredient composition into the die chamber.

17. The method of claim 15 , further comprising:

g. moving the magazine relative to the die chamber, until the magazine assumes a position in which a linearly adjustable plunger of the magazine, which has a die at a free end, faces an opening of the die chamber;

h. displacing the plunger from a release position, in which the plunger with its die is out of engagement with the die chamber, into an extended position, in which the plunger with its die projects into the die chamber via the opening, the at least one active substance metered into the die chamber and, if appropriate, a binder being compressed.

18. The method of claim 15 , further comprising:

i. displacing the magazine relative to the die chamber until the magazine assumes a position in which a carrier material container of the magazine, in which a carrier material is stored, faces with its nozzle the die chamber and/or a base plate having the die of a tablet package; and

j. Metering the carrier material into the die chamber and/or the die of the base plate.

19. The method of claim 18 , wherein dispensing the carrier material into the die chamber comprises forming an active ingredient capsule and/or dispensing the carrier material into the die of the base plate comprises forming a tablet package.
