摘要： The invention relates to a rotary tablet press comprising: a rotatingly drivable rotor, having a die plate comprising die holes and assigned to the die holes upper and lower punches, rotating synchronously with the die plate, whose axial movement is controlled by upper and lower control cams, having at least one filling station comprising at least one filling device for filling the die holes with material to be pressed, having at least one compression station disposed downstream of the filling station in the rotational direction of the rotor, comprising at least one pressing device which presses the upper and/or lower punches into the die holes when passing through the compression station in order to press the filled material in the die holes, and having at least one ejector station, disposed downstream of the compression station in the rotational direction of the rotor, comprising an ejector device for ejecting the pressed tablets in the die holes, characterized in that at least one vibration generator is provided in the circumferential direction of the upper and lower punches between the filling station and the ejector station that at least temporarily vibrates the upper and/or lower punches at least at the compression station and/or at the filling station and/or at least at an upper control cam and/or at least at a lower control cam.

摘要： A method and system for feeding a lubricating or releasing agent from a dosing station to one or more pressing tools arranged in a pressing chamber of a tablet press. The tablet press is configured with a feed pipe for feeding the lubricating or release agent from the dosing station to the one or more pressing tools of a pressing chamber of the tablet press and the feed pipe is configured with a shut-off valve disposed in-line with the feed pip for controlling the flow of the lubricating or release agent to the pressing chamber. The method comprises the steps of: producing a negative pressure with respect to the surroundings of the pressing chamber of the tablet press, measuring a pressure in one of the feed pipe and the pressing chamber, and issuing a signal indicative of the measured pressure and issuing an enable signal to open a valve in response to the pressure signal.

摘要： A filling apparatus comprises a filling material reservoir and a filling chamber that is connected to the filling material reservoir with a filling opening configured to dispense filling material into cavities in the rotary press. A first rotatably driven stirrer blade wheel with one or more stirrer blades and a second rotatably driven stirrer blade wheel with one or more stirrer blades are arranged in the filling chamber. The first rotatably driven stirrer blade wheel has at least one of a different geometry, a different direction of rotation, or a different rotary speed, than the second rotatably driven stirrer blade wheel.
