Abstract

Vorrichtung zur Führung von Unterstempeln über den Unterstempelkopf in einer einen Rotor aufweisenden Rundläuferpresse im Bereich einer Befüllvorrichtung, wobei eine Füllkurve zwischen einer in Produktionsrichtung gesehen vorangehenden Auswerferkurve und einer höhenverstellbaren Dosierkurve angeordnet und so ausgebildet ist, daß die Köpfe der mit dem Rotor umlaufenden Unterstempeln vom Niveau am Ende der Auswerferkurve auf ein tiefer liegendes Übergangsniveau der Dosierkurve abgesenkt werden, wobei ein pressenfestes erstes Füllkurvenelement mit einem sich an die Auswerferkurve anschließenden ersten Führungskurvenabschnitt versehen ist, an dem allein die Unterstempelköpfe auf der der Rotorachse zugekehrten Seite im Anschluß an die Auswerferkurve geführt sind, ein verstellbares zweites Füllkurvenelement vorgesehen ist, mit einem zweiten Füllkurvenabschnitt, an dem die Unterstempelköpfe allein auf der der Rotorachse abgekehrten Seite geführt sind, bevor sie auf die Dosierkurve treffen, das zweite Füllkurvenelement zwecks Verstellung der Fülltiefe entlang einer vorgegebenen Verstellsteigung sowohl vertikal als auch in Umfangsrichtung des Rotors verstellbar ist und erstes und zweites Füllkurvenelement dritte schraubenlinienförmige Füllkurvenabschnitte aufweisen, die zwischen dem ersten und dem zweiten Füllkurvenabschnitt und sich teilweise gegenüber liegen und die Unterstempelköpfe über eine bestimmte Strecke gemeinsam führen, wobei die Steigung der dritten Füllkurvenabschnitte der Verstellsteigung entspricht.

Figure imgaf001
Device for guiding Unterstempeln on the lower punch head in a rotor having rotary press in the region of a filling device, wherein a filling curve between a seen in the production direction preceding Auswerferkurve and a height-adjustable Dosierkurve arranged and designed so that the heads of the rotating with the rotor lower punches from the level at the end of the Auswerferkurve be lowered to a lower lying transition level of the metering, wherein a press-tight first Füllkurvenelement is provided with a subsequent to the Auswerferkurve first guide curve section on which only the lower punch heads are guided on the rotor axis side facing the ejector, an adjustable second Füllkurvenelement is provided, with a second Füllkurvenabschnitt where the Unterstempelköpfe are guided alone on the side facing away from the rotor axis before moving to the Dosi erkurve, the second Füllkurvenelement for the purpose of adjusting the filling depth along a predetermined Verstellsteigung both vertical and in the circumferential direction of the rotor is adjustable and first and second Füllkurvenelement have third helical Füllkurvenabschnitte lying between the first and second Füllkurvenabschnitt and partially opposite and Unterstempelköpfe lead over a certain distance together, the slope of the third Füllkurvenabschnitte the Verstellsteigung corresponds.
