Filling unit for a rotary press and a method for providing an optimized rotary press

A filling unit (10) for a rotary press (12), the filling unit (10) comprising:

• a filling wheel (14) configured to fill a medium to be dosed into die bores (16) of a die disk (18) of the rotary press (12);
• wherein the filling wheel (14) is an impeller wheel (20) configured to convey the medium to be dosed by a rotating movement of blades (22);
• a dosing wheel (24) configured to dose a quantity of medium to be dosed into the respective die bores (16) of the die disk (18), wherein the dosing wheel (24) is an impeller wheel (26) configured to dose the amount of medium to be dosed by sweeping over the die bores (16) of the die disk (18) with rotating movement of blades (28);
• at least one medium feed unit (36) configured to feed the medium to the filling wheel (14),
• wherein the blades (22, 28) of the filling wheel (14) and/or dosing wheel (24) each have a conveying surface (40) with which the respective impeller wheel (20, 26) conveys the medium,
• wherein the blades (22, 28) of the filling wheel (14) and dosing wheel (24) are configured such that the conveying surface (40) of the respective blades (22, 28) can be varied in shape,
• wherein the blades (22, 28) of the filling wheel (14) and/or dosing wheel (24) have a triangular or an at least partially rounded cross-section,
• wherein the shape of the conveying surface (40) is variable by a rotation of the blades (22, 28) and without disassembly and/or replacement of the blades (22, 28) of the filling wheel (14) and/or dosing wheel (24) about a respective extension axis (38),
• or by a variable inclination of the blades (22, 28) and without disassembly and/or replacement of the blades (22, 28) of the filling wheel (14) and/or dosing wheel (24) with respect to a radial direction (45) extending from an axis of rotation (42) of the respective impeller wheel (20, 26),
• or by a variable curvature of the blades (22, 28) and without disassembly and/or replacement of the blades (22, 28) of the filling wheel (14) and/or dosing wheel (24).
