Abstract

A filling apparatus comprises a filling material reservoir and a filling chamber that is connected to the filling material reservoir with a filling opening configured to dispense filling material into cavities in the rotary press. A first rotatably driven stirrer blade wheel with one or more stirrer blades and a second rotatably driven stirrer blade wheel with one or more stirrer blades are arranged in the filling chamber. The first rotatably driven stirrer blade wheel has at least one of a different geometry, a different direction of rotation, or a different rotary speed, than the second rotatably driven stirrer blade wheel.

First claim

1 . A filling apparatus for filling cavities in a rotary press, the filling apparatus comprising:
a filling material reservoir; a filling chamber connected to the filling material reservoir and having a filling opening configured to allow filling material to pass through; a first rotatably driven stirrer blade wheel having at least one stirrer blade; and a second rotatably driven stirrer blade wheel having at least one stirrer blade; wherein the first rotatably driven stirrer blade wheel and the second rotatably driven stirrer blade wheel are disposed in the filling chamber, and wherein the at least one stirrer blade of the first rotatably driven stirrer blade wheel has at least one of a different geometry, a different direction of rotation, or a different rotary speed, than the at least one stirrer blade of the second rotatably driven stirrer blade wheel.

2 . The filling apparatus according to claim 1 , wherein the first rotatably driven stirrer blade wheel and the second rotatably driven stirrer blade wheel are disposed along a common rotary axis in the filling chamber.

3 . The filling apparatus according to claim 2 , wherein the first rotatably driven stirrer blade wheel and the second rotatably driven stirrer blade wheel are rotatably driven on concentric rotary shafts.

4 . The filling apparatus according to claim 1 , wherein the at least one stirrer blade of one of the first and second rotatably driven stirrer blade wheels comprises a flat bar.

5 . The filling apparatus according to claim 1 , wherein the at least one stirrer blade of one of the first and second rotatably driven stirrer blade wheels comprises a round bar.

6 . The filling apparatus according to claim 5 , wherein the at least one stirrer blade comprising the round bar is disposed in the filling chamber above the at least one stirrer blade comprising a flat bar.

7 . The filling apparatus according to claim 1 , wherein the at least one stirrer blade of the first and second rotatably driven stirrer blade wheel each lie in a same plane.

8 . The filling apparatus according to claim 1 , wherein the at least one stirrer blade of the first and second rotatably driven stirrer blade wheel each lie in different planes.

9 . The filling apparatus according to claim 1 , wherein the at least one stirrer blade of one of the first and second rotatably driven stirrer blade wheels has one or more offsets.

10 . The filling apparatus according to claim 1 , further comprising one or more additional rotatably driven stirrer blade wheels disposed in the filling chamber, the one or more additional rotatably driven stirrer blade wheels having at least one of a different geometry, a different direction of rotation, or a different rotary speed, than the first and second rotatably driven stirrer blade wheels.

11 . The filling apparatus according to claim 1 , further comprising at least one additional filling chamber.

12 . The filling apparatus according to claim 11 , further comprising at least one additional rotatable driven stirrer blade wheel disposed in the at least one additional filling chamber.

13 . The filling apparatus according to claim 1 , further comprising a control apparatus configured to control rotary speed and direction of rotation of the first and the second rotatably driven stirrer blade wheels.

14 . A rotary press comprising;
a rotor configured to be rotated by means of a rotary drive, the rotor comprising,
an upper punch guide for upper press punches,
a lower punch guide for lower press punches, and
a die plate disposed between the upper punch guide and the lower punch guide, the die plate having a plurality of cavities, wherein the upper press punches and the lower press punches are configured to interact with the plurality of cavities in the die plate,
a filling apparatus configured to house filling material and dispense the filling material into the plurality of cavities in the die plate; at least one upper pressing apparatus and at least one lower pressing apparatus configured to interact with the upper press punches and the lower press punches to press the filling material into the plurality of cavities in the die plate to form pellets; and an ejection apparatus configured to eject the pellets from the plurality of cavities.
