Abstract

Verfahren zur Versuchspressung von Tabletten mit einer Rundläufer-Tablettiermaschine, mit einem drehend angetriebenen Rotor (10), der eine Reihe von Ober- und Unterstempeln, eine Matrizenscheibe (12) mit Matrizen (14), mit denen die Stempel zusammenwirken, ein Steuerkurvensystem für die Stempel und eine Füllanordnung (26) zur kontinuierlichen Befüllung der Matrizen (14) bei drehendem Rotor (10) aufweist, ferner mit mindestens einer Druckstation, an der das in den Matrizen (14) befindliche Material zu einer Tablette gepreßt wird und einer mehrere Meßstellen aufweisenden Meßvorrichtung, von welcher mindestens die von den Stempeln ausgeübte Preßkraft und die Drehzahl des Rotors (10) gemessen wird, mit den folgenden Verfahrensschritten:Method for test-pressing tablets with a rotary tableting machine, comprising a rotatably driven rotor (10) having a series of upper and lower punches, a die plate (12) with dies (14) with which the punches interact, a control cam system for the A punch and a filling assembly (26) for continuously filling the dies (14) with rotating rotor (10), further comprising at least one printing station at which the material in the dies (14) is pressed into a tablet and having a plurality of measuring points Measuring device, of which at least the pressing force exerted by the punches and the rotational speed of the rotor (10) is measured, with the following method steps:

ein für eine Einzelpressung ausgewähltes Stempelpaar wird automatisch auf eine Füllposition gefahren
bei zumindest teilweise entfernter Füllanordnung und stillstehendem Rotor wird eine Matrize (14) oder eine beschränkte Anzahl von Matrizen (14) mit Material befüllt
der Rotor (10) wird anschließend in Drehung versetzt und so beschleunigt, daß er in der Druckstation die gewünschte Produktionsgeschwindigkeit hat
nach einer Umdrehung wird der Rotor (10) in der Füllposition angehalten und
während der Umdrehung des Rotors (10) werden Signale oder Signalverläufe der Meßstellen aufgezeichnet und in einen Rechner zur Anzeige und Auswertung gegeben.

Figure imgaf001
a stamp pair selected for a single press is automatically moved to a filling position
With at least partially removed filling arrangement and stationary rotor, a die (14) or a limited number of dies (14) is filled with material
the rotor (10) is then rotated and accelerated so that it has the desired production speed in the printing station
after one revolution, the rotor (10) is stopped in the filling position and
during the rotation of the rotor (10) signals or waveforms of the measuring points are recorded and placed in a computer for display and evaluation.
