Abstract
A rotor for a rotary press comprising a die plate having die bores and upper punches and lower punches assigned in pairs to the die bores, circulating synchronously with the die plate An upper punch receiver is configured to axially guide the upper punches and a lower punch receiver is configured to axially guide the lower punches. An upper control cam is configured to control the axial movement of the upper punches passing through the upper control cam and a lower control cam is configured to control the axial movement of the lower punches passing through the lower control cam.
Claims14
A rotor for a rotary press comprising:
- a die plate having die bores and upper punches and lower punches assigned in pairs to the die bores, the upper and lower punches configured to circulate synchronously with the die plate;
- an upper punch receiver configured to guide the upper punches;
- a lower punch receiver configured to guide the lower punches;
- an upper control cam configured to control axial movement of the upper punches passing through the upper control cam;
- a lower control cam configured to control axial movement of the lower punches passing through the lower control cam;
- at least one upper contact part in contact with at least a portion of the upper punches passing through;
- at least one lower contact part in contact with at least a portion of the lower punches passing through;
- at least one upper adjusting element configured to adjust a position of the at least one upper contact part by altering a distance from the upper punches passing through, wherein the at least one upper contact part is always pressed with a substantially constant force onto the upper punches passing through;
- and
- at least one lower adjusting element configured to adjust a position of the at least one lower contact part by altering a distance from the lower punches passing through, wherein the at least one lower contact part is always pressed with a substantially constant force against the lower punches passing through.

A rotary press comprising:
- a rotor, the rotor further comprising a die plate having die bores, upper punches and lower punches assigned in pairs to the die bores, wherein the upper and lower punches configured to circulate synchronously with the die plate;
- a drive configured to rotationally drive the rotor;
- an upper punch receiver configured to guide the upper punches;
- a lower punch receiver configured to guide the lower punches;
- an upper control cam configured to control axial movement of the upper punches passing through the upper control cam;
- a lower control cam configured to control axial movement of the lower punches passing through the lower control cam;
- at least one upper contact part in contact with at least a portion of the upper punches passing through;
- at least one lower contact part in contact with at least a portion of the lower punches passing through;
- at least one upper adjusting element configured to adjust a position of the at least one upper contact part by altering a distance from the upper punches passing through, wherein the at least one upper contact part is always pressed with a substantially constant force onto the upper punches passing through;
- at least one lower adjusting element configured to adjust a position of the at least one lower contact part by altering a distance from the lower punches passing through, wherein the at least one lower contact part is always pressed with a substantially constant force against the lower punches passing through;
- at least one filling station, the at least one filling station comprising at least one filling device for filling the die bores with material to be compressed;
- at least one pressing station located downstream of the at least one filling station and comprising at least one pressing device which presses the upper punches and lower punches into the die bores when passing through the at least one pressing station;
- and
- at least one ejection station located downstream of the pressing station in a rotational direction of the rotor and comprising an ejection device for ejecting tablets pressed into the die bores.
