OG exemplary drawing
 
1. 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 metered into die holes (16) of a die plate (18) of the rotary press (12);
wherein the filling wheel (14) is configured as an impeller (20) and is configured to deliver the medium to be metered via a rotating movement by its vanes (22);
a metering wheel (24) configured to meter a quantity of medium to be metered into the respective die holes (16) of the die plate (18), wherein the metering wheel (24) is configured as an impeller (26) and is configured to meter the quantity of the medium to be metered and to remove excess medium by scraping over the die holes (16) of the die plate (18) with its vanes (28) via a rotating movement;
a feeding wheel (30) configured to feed the medium to be metered to the filling wheel (14),
wherein the feeding wheel (30) is configured as an impeller (32) and is configured to deliver the medium to be supplied to the filling wheel (14) via a rotating movement by its vanes (34);
at least one medium supply unit (36) which is designed to supply the medium to the filling wheel (14) and/or the feeding wheel (30),
wherein the vanes (22, 28, 34) of the filling wheel (14), the metering wheel (24) and/or the feeding wheel (30) each have a delivery surface (40) with which each of the impellers (20, 26, 32) delivers the medium,
wherein the filling unit (10) is configured in such a manner that the feeding wheel (30) is configured to connect and disconnect from a delivery path of the medium to be metered by movement created by a device.
