Description
Die Erfindung bezieht sich auf eine Rundlaufpresse nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a rotary press according to the preamble of patent claim 1.
Bei einer Rundlaufpresse ist ein Rotor in einem Gestell um eine Hochachse drehbar gelagert und angetrieben. Der zumeist einteilige Rotorkörper enthält eine obere und eine untere Stempelaufnahme für Ober- und Unterstempel, welche in Bohrungen achsparallel geführt sind. Die Pressstempel wirken mit Bohrungen einer Matrizenscheibe zusammen, die entweder einteilig mit dem Rotorkörper geformt ist oder ein getrenntes Teil darstellt. Aus
Während der Umdrehung des Rotors werden die Pressstempel axial bewegt. Ein Großteil der Bewegungen wird von Steuerkurven bewerkstelligt. Zu diesem Zweck sind an Kurvenhaltern im Gestell Steuerkurvenelemente angebracht, welche mit der Oberseite und/oder der Unterseite des Kopfs der Pressstempel zusammenwirken. Lediglich im Bereich von Pressstationen mit oberer und unterer Druckrolle sind die Pressstempel nicht von Steuerkurven geführt.During the rotation of the rotor, the ram are moved axially. Much of the movement is done by cams. For this purpose, cam members are mounted on curve holders in the frame, which cooperate with the top and / or bottom of the head of the ram. Only in the area of pressing stations with upper and lower pressure rollers are the press punches not guided by control cams.
Aus Gründen des Verschleißes oder einer Änderung der Spezifikation ist erforderlich, die Führungskurvenelemente auszubauen und durch andere zu ersetzen. Hierfür ist im Stand der Technik erforderlich, Maschinenverkleidungsteile und die Fülleinrichtung aus dem Pressengestell zu entfernen und mehrere Stempel oder die Matrizenscheibe mit den Pressstempeln auszubauen. Außerdem ist in der Maschine befindliches Pulver abzusaugen. Der Montageaufwand ist daher erheblich. Außerdem ist während der Montagezeit der Betrieb der Rundlaufpresse naturgemäß unterbrochen. Der Austausch von Steuerkurvenelementen führt daher zu einer erheblichen Unterbrechung der Produktionszeit.For reasons of wear or a change in specification, it is necessary to remove the guide cam elements and replace them with others. For this purpose, the prior art requires machine trim parts and to remove the filling device from the press frame and to remove a plurality of punches or the die plate with the press dies. In addition, powder in the machine is to be sucked off. The installation effort is therefore significant. In addition, the operation of the rotary press is naturally interrupted during the assembly time. The replacement of cam elements therefore leads to a significant interruption of production time.

Der Erfindung liegt die Aufgabe zugrunde, eine Rundlaufpresse zu schaffen, bei der Steuerkurvenelemente ausgebaut werden können, ohne die Pressstempel vorher zu entfernen.The invention has for its object to provide a rotary press, can be removed in the control cams without removing the ram before.
Diese Aufgabe wird durch die Merkmale des Patentanspruchs 1 gelöst.This object is solved by the features of patent claim 1.
Bei der Erfindung ist mindestens ein in Laufrichtung der Pressstempel die Pressstempelköpfe radial innen und/oder ein radial außen führendes Steuerkurventeil vorgesehen. Erfindungsgemäß sind die Steuerkurventeile lösbar am Kurventräger befestigt und können - wenn gelöst - radial von den Stempelköpfen fort bewegt werden, und zwar soweit, dass sie parallel zur Rotorachse an den Stempelköpfen vorbei nach oben oder unten herausgenommen werden können. Es versteht sich, dass die Steuerkurventeile nur von der Seite von den Pressstempeln radial fort bewegt werden kann, an der sie an den Pressstempelköpfen anliegen.In the invention, at least one in the running direction of the ram, the press ram heads radially inside and / or a radially outside leading cam part is provided. According to the invention, the control cam parts are releasably attached to the cam carrier and can - if solved - are moved radially away from the punch heads, to the extent that they can be taken parallel to the rotor axis past the stamp heads up or down. It is understood that the control cam parts can only be moved radially away from the side of the press dies, against which they rest against the press die heads.
Bei gegenüberliegend an den Stempelköpfen angreifenden Steuerkurventeilen sind die Steuerkurvenabschnitte jeweils einem eigenen Steuerkurventeil zugeordnet. Beide Steuerkurventeile sind lösbar am Kurventräger befestigt. Beide Steuerkurventeile weisen einen Steuerkurvenabschnitt auf, die auf gegenüberliegenden Seiten an den Köpfen der Pressstempel angreifen. Die Anordnung der Steuerkurventeile relativ zum Kurventräger ist derart, dass die Steuerkurventeile nach dem Lösen vom Kurventräger zunächst radial auseinanderbewegbar und anschließend parallel zur Achse des Rotors bewegt werden können.In opposite to the punch heads attacking control cam parts, the cam sections are each assigned to a separate control curve part. Both cam parts are releasably attached to the cam carrier. Both cam parts have a cam portion which engage on opposite sides of the heads of the ram. The arrangement of the control cam parts relative to the cam carrier is such that the control cam parts after release from the cam carrier can first be moved radially apart and then moved parallel to the axis of the rotor.
Das Steuerkurvenelement bei der Erfindung ist zweigeteilt und die Einzelteile können getrennt entfernt werden, ohne dass hierfür die Pressstempel zuvor entnommen werden müssen. Die Pressstempel können daher in der Presse verbleiben. Der Wechsel der Steuerkurvenelemente kann bei der Erfindung schnell vonstatten gehen, wodurch geringere Stillstandszeiten bei einer Umrüstung nötig werden.The cam member in the invention is divided into two parts and the items can be removed separately, without the need for the press stamps must be removed beforehand. The press punches can therefore remain in the press. The change of the cam elements can go quickly in the invention, whereby less downtime during retrofitting are necessary.
Besonders vorteilhaft ist die Erfindung bei dem Einsatz von Rundlaufpressen, bei denen beabsichtigt ist, auch zu Reinigungszwecken Rotor und Pressstempel in der Presse zu belassen. Dies ist möglich, indem der Rotor von einem dichtenden Gehäuse umgeben ist, das einen relativ kleinen Pressraum innerhalb des Pressengehäuses bildet. Das Gehäuse ist so ausgeführt, dass die aus dem Rotor herausragenden oberen und unteren Enden der Pressstempel, die mit den Steuerkurven zusammenwirken, außerhalb des Pressraums liegen. Die Pressstempel sind ihrerseits dichtend in den Bohrungen der Stempelaufnahmen geführt.Particularly advantageous is the invention in the use of rotary presses, in which it is intended, also for cleaning rotor and ram to leave in the press. This is possible by surrounding the rotor with a sealing housing which forms a relatively small pressing space within the press housing. The housing is designed so that the protruding from the rotor upper and lower ends of the ram, which cooperate with the cams, outside the baling chamber lie. The press punches are themselves sealingly guided in the bores of the stamp holders.
In einer Ausgestaltung der Erfindung weisen die Steuerkurventeile radiale Flanschabschnitte auf, wobei der Flanschabschnitt des radial äußeren Steuerkurventeils den Flanschabschnitt des radial inneren Steuerkurventeils überdeckt. In einer weiteren Ausführungsform ist vorgesehen, dass die Flanschabschnitte gegeneinander gespannt sind, wenn sie mittels Schrauben am Kurventräger befestigt sind.In one embodiment of the invention, the control cam parts have radial flange sections, wherein the flange section of the radially outer control cam section covers the flange section of the radially inner control cam section. In a further embodiment it is provided that the flange portions are tensioned against each other when they are fastened by means of screws on the cam carrier.
Es sind verschiedene Anbringungsweisen der Steuerkurventeile am Kurventräger denkbar. Eine besteht nach einer Ausgestaltung der Erfindung darin, dass das radial innere Steuerkurventeil am Kurventräger befestigt ist und das radial äußere Steuerkurventeil am radial inneren Steuerkurventeil befestigt ist. Alternativ kann nach einer anderen Ausgestaltung der Erfindung vorgesehen sein, dass das innere Steuerkurventeil einen radial nach außen weisen Flanschabschnitt aufweist, der den äußeren Steuerkurventeil überdeckt.There are different ways of mounting the cam parts on the cam carrier conceivable. One according to an embodiment of the invention is that the radially inner cam part is attached to the cam carrier and the radially outer cam part is fixed to the radially inner cam part. Alternatively it can be provided according to another embodiment of the invention that the inner cam part has a radially outwardly pointing flange portion which covers the outer cam part.
