  • Publication number: 20250115019
    Abstract: A rotary press (10), in particular a rotary tablet press, includes a rotor (14) rotatable about an axis of rotation (12) and a cleaning device (16) for cleaning the rotary press (10). The cleaning device (16) includes at least one spray opening (18), in particular a plurality of spray openings (18), for spraying a cleaning agent (20). The cleaning device (16) is coupled to the rotor (14) and configured such that the spray opening (18) can be rotated about the axis of rotation (12) by rotating the rotor (14). A method for cleaning such a rotary press (10) is also described.

  • Publication number: 20230382072
    Abstract: A filling unit (10) for a rotary press (12) with a filling wheel (14), a dosing wheel (24), optionally a feed wheel (30) and a medium feed unit (36), wherein the blades (22, 28, 34) of the filling wheel (14), dosing wheel (24) and/or feed wheel (30) designed as an impeller wheel (20, 26, 32), are designed in such a way that a conveying surface (40) of the respective blades (22, 28, 34) can be varied in shape, and a method for providing an optimized rotary press is proposed.

  • Publication number: 20230382073
    Abstract: Disclosed is a filling unit (10) for a rotary press (12), comprising a filling wheel (14), a metering wheel (24), a feeding wheel (30) and a medium unit (36), wherein the filling unit (10) is designed in such a way that the feeding wheel (30) can be connected to and disconnected from a delivery path of the medium to be metered, in particular by having a pivoting device (33) perform a pivoting movement, in particular about an axis of rotation (42) of the metering wheel (24), which is in the form of an impeller (20, 26, 32). Also disclosed is a method for providing an optimized rotary press.

  • Patent number: 8266874
    Abstract: The invention relates to a weighing device for a packaging machine. Empty capsules that are still closed are removed from a capsule holder, weighed on a gravimetric scale, placed back into an empty capsule holder, and then taken apart. The device makes it possible to remove empty capsules and replace them at full machine speed, without a loss of any consequence in output. It is possible to use a gravimetric measurement method to carry out a tare weighing of the capsules. An additional weighing device for filled capsules is integrated into a capsule transport device to determine the net weight based on the tare weight and the weight of the full capsules. Such a combination of a gravimetric tare weighing and a gross weighing to statistically determine the net weight is particularly well-suited to an intermediate capsule filling device.
