Abstract

The method involves pressing of the upper stamp stands on the pressing part and lifts with it during the stamping process and the scrapper (36) laterally catches the scrapping part, while the upper stamp still lifts on the pressing. The rotor (10) with the die plate has an upper and lower stamp. An independent claim is also included for the rotary press.

Description

Die Erfindung bezieht sich auf ein Verfahren nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a method according to the preamble of patent claim 1.

Es ist bekannt, zur Herstellung von Tabletten und ähnlichen Preßlingen Rundläuferpressen zu verwenden. Diese weisen einen um eine vertikale Achse drehbar gelagerten und angetriebenen Rotor auf, wobei der Rotor eine Matrizenscheibe und Stempelführungen für Ober- und Unterstempel aufweist. Diese Ober- und Unterstempel werden von geeigneten Steuerkurven geführt und in mindestens einer Preßstation sind eine obere und eine untere Preßrolle oder Druckrolle angeordnet, mit deren Hilfe die Preßstempel das in den Matrizen befindliche zu komprimierende Material verpressen.It is known to use for the production of tablets and similar compacts rotary presses. These have a rotatably mounted about a vertical axis and driven rotor, wherein the rotor has a die plate and punch guides for upper and lower punch. These upper and lower punches are guided by suitable cams and in at least one pressing station, an upper and a lower pressure roller or pressure roller are arranged, with the help of which the press ram compress the located in the matrices to be compressed material.

Manche zu verpressenden Materialien neigen dazu, nach dem Preßvorgang an der Preßfläche der Oberstempel anzuhaften, wenn der Oberstempel seinen Rückhub beginnt. Dieser Effekt führt dazu, dass die Oberfläche des Preßlings nicht die gewünschte Qualität hat und zudem den nächsten Preßvorgang ungünstig beeinflußt. Aus EP 0 448 190 B1 oder DE 88 16 064 U1 ist bekannt geworden, die Stempel drehbar in den Stempelführungen zu lagern und während des Rückhubs nach einem Preßvorgang in Drehung zu versetzen. Mit Hilfe der Drehung der Stempel wird der Anhafteffekt weitgehend unterbunden. Aus DE 100 24 340 C2 ist bekannt, einen Stempeleinsatz drehbar im Stempelschaft zu lagern, wobei der Einsatz einen Ansatz aufweist, der zwischen zwei axial beabstandeten Anschlägen schraubenlinienförmig geführt wird. Eine Feder spannt den Einsatz vom Stempelschaft fort nach unten.Some materials to be pressed tend to adhere to the pressing surface of the upper punches after the pressing operation when the upper punch starts its return stroke. This effect causes the surface of the compact does not have the desired quality and also affects the next pressing unfavorable. Out EP 0 448 190 B1 or DE 88 16 064 U1 It has become known to support the stamp rotatably in the punch guides and to set during the return stroke after a pressing operation in rotation. With the help of the rotation of the stamp the adhesion effect is largely prevented. Out DE 100 24 340 C2 It is known to rotatably support a punch insert in the punch shaft, wherein the insert has a lug which is guided helically between two axially spaced stops. A spring tensions the insert away from the punch shaft.

Während des Rückhubs der Oberstempel findet eine Entlastung statt, bei der sich der Oberstempel normalerweise innerhalb der Matrize befindet .Ist der Preßling unrund, beispielsweise quadratisch, kommt eine Drehung der Preßstempel bzw. der Einsätze nicht in Betracht.During the return stroke of the upper punch takes place a relief in which the upper punch is usually located within the die. If the compact out of round, such as square, a rotation of the ram or inserts is out of the question.

Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren zum Betrieb einer Rundläuferpresse anzugeben, bei dem ein Entfernen der Preßlinge ohne Anhaften von Material des Preßlings unabhängig von der Querschnittsform der Matrizen möglich ist.The invention has for its object to provide a method for operating a rotary press, in which removal of the compacts without adhesion of material of the compact is independent of the cross-sectional shape of the dies possible.

Diese Aufgabe wird durch die Merkmale des Patentanspruchs 1 gelöst.This object is solved by the features of patent claim 1.

Bei dem Verfahren nach der Erfindung ruht der Oberstempel mit seinem Eigengewicht nach wie vor auf dem Preßling, wenn dieser mit Hilfe des Unterstempels aus der Matrize ausgestoßen wird. Sobald der Preßling unmittelbar oberhalb der Oberkante der Matrize ist, kann er von einem Abstreifer abgestreift werden, wobei während dieses Vorgangs zumindest noch vorübergehend der Oberstempel weiterhin auf dem Preßling aufsteht. Es versteht sich, dass der Oberstempel von einem Kurvenabschnitt der oberen Steuerkurve erfaßt werden muß, bevor der Abstreifer den Preßling vollständig zwischen den Stempeln fortgeschoben hat, da anderenfalls der Oberstempel mit seiner Preßfläche mit dem Abstreifer in Eingriff treten würde, was naturgemäß vermieden werden muß.In the method according to the invention, the upper punch still rests with its own weight on the compact when it is ejected from the die with the aid of the lower punch. Once the compact is just above the upper edge of the die, it can be stripped by a scraper, during which process, at least temporarily, the upper punch still stands up on the compact. It is understood that the upper punch must be detected by a curve portion of the upper cam before the scraper has pushed the compact completely between the punches, otherwise the upper punch with its pressing surface would engage with the scraper, which must be avoided by nature.

Eine Rundläuferpresse nach der Erfindung sieht Steuerkurven vor, wobei in Drehrichtung des Rotors hinter der Preßstation die Oberstempel in der Höhe nicht geführt sind, wodurch die Oberstempel in diesem Bereich durch Eigengewichte nach unten "vorgespannt" sind. Sie können daher weiterhin auf dem Preßling aufstehen und diesen mit ihrem Gewicht belasten. Das Abschieben des Preßlings zwischen den Preßflächen der Stempel erfolgt über eine gewisse Strecke, mindestens z.B. 0,5 mm, bevor der Oberstempel dann abgehoben wird.A rotary press according to the invention provides control cams, wherein in the direction of rotation of the rotor behind the pressing station, the upper punches are not guided in height, whereby the upper punches in this area are "biased" by own weights down. You can therefore continue to get up on the compact and weight it. The pushing off of the compact between the pressing surfaces of the stamp takes place over a certain distance, at least for example 0.5 mm, before the upper punch is then lifted off.

Aus den obigen Gründen versteht sich, dass der Abstreifer eine Dicke hat, die kleiner ist als die Dicke des Preßlings. Vorzugsweise greift der Abstreifer etwa mittig zwischen den Preßflächen am Preßling an, um diesen abzustreifen.For the above reasons, it is understood that the scraper has a thickness which is smaller than the thickness of the compact. Preferably, the scraper engages approximately centrally between the pressing surfaces on the compact in order to strip it.

Während des Abstreifens ist es nach einer Ausgestaltung der Erfindung vorteilhaft, wenn ein Kurvenabschnitt der unteren Führungskurve für die Unterstempel horizontal verläuft, wodurch der Preßling nicht weiter angehoben wird als minimal oberhalb der Oberseite der Matrizenplatte.During stripping, it is advantageous according to an embodiment of the invention, when a curve portion of the lower guide curve for the lower punch is horizontal, whereby the compact is not raised further than minimally above the top of the die plate.

Das erfindungsgemäße Verfahren und die erfindungsgemäße Rundläuferpresse weisen folgende Vorteile auf: Durch das Abstreifen mit der Auflast durch den Oberstempel wird ein Anhaften von Preßlingsmaterial an den Preßflächen der Stempel verhindert. Dadurch wird eine kontinuierliche Produktion gewährleistet. Reinigungsprozesse an den Stempelpreßflächen entfallen. Die mechanischen Vorkehrungen an der Rundläuferpresse zur Durchführung des erfindungsgemäßen Verfahrens sind denkbar einfach. Insgesamt können problematische Produktmischungen in Rundläuferpressen verpreßt werden, was bislang nicht möglich war.The inventive method and the rotary press according to the invention have the following advantages: By stripping with the ballast by the upper punch adhesion of Preßlingsmaterial is prevented at the pressing surfaces of the stamp. This ensures continuous production. Cleaning processes at the Stempelpreßflächen omitted. The mechanical precautions on the rotary press for carrying out the method according to the invention are very simple. Overall, problematic product mixtures can be pressed in rotary presses, which was previously not possible.

Ein Ausführungsbeispiel der Erfindung wird nachfolgend anhand von Zeichnungen näher erläutert.

In Fig. 1 ist ein Rotor 10 einer Rundläuferpresse angedeutet, bei dem auf einem Teilkreis Matrizen 12 in einer Matrizenscheibe angeordnet sind, zur Aufnahme von zu verpressendem Material. Das Einfüllen des zu verpressenden Materials erfolgt in einer Fülleinrichtung 14, die im Einzelnen nicht weiter beschrieben werden soll. Mit Hilfe der Befülleinrichtung ist es möglich, eine Sorte oder mehrere Schichten von Material in die Matrizen einzufüllen. Dem Rotor 10 sind Ober- und Unterstempel zugeordnet, die in Figur 1 nicht gezeigt sind. Sie werden von geeigneten Steuerkurven während des Umlaufs des Rotors 10, der von einer geeigneten Antriebsvorrichtung um eine vertikale Achse drehend angetrieben ist, in ihrer Höhenlage gesteuert. In einer ersten Preßstation 16 sind zwei Druckrollen übereinander angeordnet, von denen eine bei 18 dargestellt ist. Die Druckrollen drücken Unter- und Oberstempel in die Matrizen 12 hinein, um das Material zu verpressen. Eine zweite Preßstation 20 weist ebenfalls zwei übereinander liegende Druckrollen auf, von denen eine bei 22 zu erkennen ist. In der Preßstation 20 erfolgt die fertige Verpressung des Materials in den Matrizen 12. Ein derartiger Aufbau bzw. eine derartige Funktion einer Rundläuferpresse ist allgemein bekannt.In Fig. 1, a rotor 10 of a rotary press is indicated in which are arranged on a pitch circle matrices 12 in a die plate, for receiving material to be pressed. The filling of the material to be pressed takes place in a filling device 14, which will not be described in detail further. With the help of the filling device, it is possible to fill one or more layers of material in the matrices. The rotor 10 are associated with upper and lower punches, which are not shown in Figure 1. They are controlled by suitable cams during the rotation of the rotor 10, which is driven by a suitable drive device rotating about a vertical axis, in its altitude. In a first pressing station 16 two pressure rollers are arranged one above the other, one of which is shown at 18. The pressure rollers press lower and upper punches into the dies 12 to press the material. A second press station 20 also has two superimposed pressure rollers, one of which can be seen at 22. In the pressing station 20, the finished pressing of the material takes place in the matrices 12. Such a structure or such a function of a rotary press is generally known.

In Figur 2 ist der beschriebene Ablauf schematisch in Abwicklung dargestellt. Die Darstellung erfolgt anhand eines Stempelpaars mit einem Oberstempel 24 und einem Unterstempel 26. Die Matrizen 12 sind schraffiert angedeutet. Die Steuerkurve für die Oberstempel 24 ist sehr schematisch bei 26a gezeigt. Die Steuerkurve für die Unterstempel 26 ist sehr schematisch bei 28 gezeigt. In der Füllposition sind Ober- und Unterstempel 24, 26 in einer am weitesten voneinander entfernten Position, wobei der Unterstempel 26 seine Befüllposition eingenommen hat. Zu verpressendes Material 30 ist punktiert angedeutet. Bei der weiteren Drehung des Rotors wird zunächst der Oberstempel 24 abgesenkt (2b). In der ersten Preßstation 16 erfolgt mit Hilfe der Druckrollen eine Verpressung des Materials zu einem Vorpreßling. In der folgenden Preßstation 20 erfolgt eine Verformung des Materials zum fertigen Preßling 32. Hinter der zweiten Preßstation 20 wird der Unterstempel 26 durch die Steuerkurve angehoben, wodurch der Preßling 32 aus der Matrize 12 ausgestoßen wird. Man erkennt, dass die obere Steuerkurve 26 hinter der zweiten Preßstation 20 eine Lücke hat. Beim Hochfahren des Unterstempels bleibt der Oberstempel 24 auf dem Preßling 32 stehen und wird mit angehoben. Der Unterstempel 26 gelangt zu einem Steuerkurvenabschnitt 34, der horizontal verläuft, wodurch der Preßling 32 nur minimal oberhalb der Oberseite der Matrize 12 angehoben bleibt. Hierbei nähert sich der Preßling 32 dem stationären Abstreifer 36, der den Preßling 32 zwischen den einander gegenüberliegenden Preßflächen von Ober- und Unterstempel herausschiebt. Die Dicke des Abstreiferblechs 36 ist geringer als die Dicke des Preßlings 32 und der Abstreifer greift annähernd mittig am Preßling an. Nachdem der Abstreifer 36 den Preßling 32 um eine gewisse Strecke zwischen den Preßflächen von Ober- und Unterstempel herausgeschoben hat, wird der Oberstempel 24 von einem Steuerkurvenabschnitt 38 erfaßt und angehoben, wodurch der Abstreifer 36 den Preßling endgültig auf die Oberseite der Matrizenscheibe schiebt, von wo er dann in einen Ablaufkanal 40 (Figur 1) gelangt.In Figure 2, the procedure described is shown schematically in settlement. The representation is based on a stamp pair with an upper punch 24 and a lower punch 26. The matrices 12 are indicated by hatching. The cam for the upper punches 24 is shown very schematically at 26a. The control cam for the lower punches 26 is shown very schematically at 28. In the filling position are upper and lower punches 24, 26 in a most distant position, the lower punch 26 has taken its Befüllposition. To be pressed material 30 is indicated by dots. Upon further rotation of the rotor, the upper punch 24 is first lowered (2b). In the first pressing station 16 takes place by means of the pressure rollers a compression of the material to a preform. In the following pressing station 20, a deformation of the material to the finished Compact 32. Behind the second pressing station 20, the lower punch 26 is lifted by the control cam, whereby the compact 32 is ejected from the die 12. It can be seen that the upper control cam 26 has a gap behind the second pressing station 20. When booting the lower punch the upper punch 24 remains standing on the compact 32 and is raised with. The lower punch 26 reaches a cam portion 34, which extends horizontally, whereby the compact 32 only minimally raised above the top of the die 12. Here, the compact 32 approaches the stationary scraper 36, which pushes the compact 32 between the opposing pressing surfaces of the upper and lower punches. The thickness of the Abstreiferblechs 36 is less than the thickness of the compact 32 and the scraper attacks approximately centrally on the compact. After the wiper 36 has pushed out the compact 32 by a certain distance between the pressing surfaces of upper and lower punch, the upper punch 24 is detected by a cam portion 38 and raised, whereby the wiper 36 pushes the compact finally on the top of the die plate, from where He then enters a drain channel 40 (Figure 1).
