  • Publication number: 20170282477
    Abstract: A rotary press comprises a rotor that can be rotated by a rotary drive. The rotor has an upper punch guide for upper press punches and a lower punch guide for lower press punches and a die plate arranged between the punch guides. The upper and lower press punches are configured interact with cavities of the die plate. A filling device loads filling material into cavities of the die plate and at least one measuring device coupled to the filling device for monitoring the availability of the filling material in the filling device. The rotary press further includes at least one upper pressing device and at least one lower pressing device that are configured to interact with the upper press punches and the lower press punches to press the filling material in the cavities of the die plate into a pellet. An ejection device is configured to eject the pellets. wherein at least one measuring device is arranged on or in the filling device for monitoring the availability of the filling material in the filling device.

  • Patent number: 8162650
    Abstract: A filling apparatus for a rotary tablet press, which itself being arranged stationarily is associated to a circulating die plate of a rotor of the tablet press, with a filling chamber, which features an upper inlet opening for powder-shaped compression material and a filling opening aligned with die bores of the die plate, and with a conveying means in the filling chamber driven by a drive motor, wherein the filling chamber is circular, one single disc-shaped filling wheel is rotatably mounted around a vertical axis in the filling chamber, which has plural wings on the perimeter, spaced apart in the perimeter direction, which sweep over the filling opening upon rotation of the filling wheel, and the inlet opening is arranged in a distance above the filling wheel, preferably approximately centered with the axis of the filling wheel.

  • Patent number: 7740468
    Abstract: A rotary press with a stand, a rotor rotatably mounted around a vertical axis in the stand and being driven, which has an upper and a lower compression punch accommodation for upper and lower punches which co-operate with bores of a die plate of the rotor, and upper and lower control cam elements which can be detachably fastened on a cam carrier of the stand and which guide heads of the compression punches by means of control cams during the rotation of the rotor, characterized in that at least one control cam element, guiding the compression punch heads radially outside or radially inside, can be detachably fastened on the carrier and can be moved radially away from the punch heads when the fastening means is detached, so far that by-passing the punch heads, it can be taken out parallel to the axis of the rotor, towards the upside or towards the bottom side, respectively.
