Abstract

A removal apparatus for removing pellets from a die plate of a rotary press comprises a housing and a first channel positioned on the housing and configured to receive pellets removed from the die plate. A guide element is arranged on the housing and positioned over the die plate. The guide element is configured to guide pellets produced in the rotary press from the die plate into the first channel. The guide element and the first channel are moveably mounted on the housing. A plurality of mechanical positioning elements are configured to be alternatively inserted into the housing and cooperate with the guide element and the first channel to movably position the guide element and the first channel relative to the housing. Each of the mechanical positioning elements defines a different position of one of the guide element and the first channel relative to the housing.

First claim

The invention claimed is:

1. A removal apparatus for removing pellets from a die plate of a rotary press, the removal apparatus comprising:
a housing;
a first channel positioned on the housing and configured to receive pellets removed from the die plate;
a guide element arranged on the housing and positioned over the die plate, the guide element configured to guide pellets produced in the rotary press from the die plate into the first channel, wherein the guide element and the first channel are moveably mounted on the housing; and
a plurality of mechanical positioning elements configured to be alternatively inserted into the housing and cooperate with the guide element and the first channel to movably position the guide element and the first channel relative to the housing, wherein each mechanical positioning element defines a different position of one of the guide element and the first channel relative to the housing.

2. The removal apparatus according to claim 1 , further comprising a second channel arranged on the housing.

3. The removal apparatus according to claim 2 , wherein the second channel is moveably mounted on the housing, and wherein the position of the second channel is defined by the plurality of mechanical positioning elements.

4. The removal apparatus according to claim 3 , wherein the pellets produced in the rotary press are guided into the second channel by the guide element, wherein the first channel is arranged upstream of the second channel.

5. The removal apparatus according to claim 4 , further comprising a discarding apparatus configured to guide discarded pellets into the first channel.

6. The removal apparatus according to claim 3 , the plurality of mechanical positioning elements comprise positioning pins configured to engage a corresponding pin receiver of the guide element and the first channel when the plurality of mechanical positioning elements are inserted in the housing.

7. A removal apparatus for removing pellets from a die plate of a rotary press, the removal apparatus comprising:
a housing;
a first channel positioned on the housing and configured to receive pellets removed from the die plate;
a second channel moveably mounted on the housing, wherein a position of the second channel is defined by a plurality of mechanical positioning elements;
a guide element arranged on the housing and positioned over the die plate, the guide element configured to guide pellets produced in the rotary press from the die plate into the first channel, wherein the guide element and the first channel are moveably mounted on the housing; and
the plurality of mechanical positioning elements configured to be alternatively inserted into the housing and cooperate with the guide element and the first channel movably position the guide element and the first channel relative to the housing, wherein each mechanical positioning element defines a different position of one of the guide element and the first channel relative to the housing,
wherein the guide element and the first channel comprise positioning pins configured to engage corresponding pin receivers of the mechanical positioning elements when inserted into the housing.

8. The removal apparatus according to claim 6 , further comprising insertion portions that lead into the corresponding pin receivers and that taper as they approach the corresponding pin receivers.

9. The removal apparatus according to claim 7 , wherein the mechanical positioning elements each comprise a guide support configured to be inserted into the housing and on which at least one of the positioning pins and the corresponding pin receivers are formed.

10. The removal apparatus according to claim 9 , wherein the guide element and the first channel are each arranged on a guide carriage that is moveably mounted on the housing.

11. The removal apparatus according to claim 10 , wherein one of the positioning pins and the corresponding pin receivers are formed on the guide carriages.

12. The removal apparatus according to claim 9 , wherein the mechanical positioning elements each comprise an identifier configured to enable each of the mechanical positioning elements to be clearly identified.

13. The removal apparatus according to claim 12 , characterized in that each of the identifiers comprises an RFID transponder than can be read by a reading apparatus of the rotary press.

14. A rotary press comprising:
a control apparatus;
a rotor, the rotor comprising,
an upper punch guide configured to guide upper press punches and a lower punch guide configured to guide lower press punches,
a die plate positioned between the upper and lower punch guides and comprising a plurality of openings, wherein the upper and lower press punches are configured to cooperate with the plurality of openings;

at least one filling station configured to load material to be pressed into the plurality of openings;
at least one pressing station configured to cooperate with the upper press punches and lower press punches during operation to press the material loaded into the plurality of openings into pellets; and
at least one ejection station configured to move the pellets from the plurality of openings onto the die plate, and at least one removal apparatus, the at least one removal apparatus comprising,
a housing,
a first channel positioned on the housing and configured to receive the pellets removed from the die plate,
a guide element arranged on the housing and positioned over the die plate, the guide element configured to guide the pellets produced in the rotary press from the die plate into the first channel, wherein the guide element and the first channel are moveably mounted on the housing, and
a plurality of mechanical positioning elements configured to be alternatively inserted into the housing and cooperate with the guide element and the first channel to movably position the guide element and the first channel relative to the housing, wherein each mechanical positioning element defines a different position of one of the guide element and the first channel relative to the housing.
