Abstract
Description
Die Erfindung betrifft einen Unterstempel für eine Tablettiermaschine, der einen Unterstempelschaft aufweist, auf dem mindestens ein Unterstempeleinsatz angeordnet ist.The invention relates to a lower punch for a tableting machine, which has a Unterstempelschaft on which at least one lower punch insert is arranged.
Derartige Teile eines Tabtettierwericzeugs darstellende Unterstempel sind bekannt und werden in Tablettiermaschinen zur Herstellung von Tabletten verwendet. Der Unterstempeleinsatz des Unterstempels wirkt hierbei mit einer Matrize zusammen, die ortsfest an der Tablettiermaschine angeordnet, ist. Bei der Tablettenherstellung, insbesondere bei der Herstellung von Pellets, mittels eines derartigen Tablettierwerkzeugs, tritt bei Unterstempeleinsätzen mit kleinen Durchmessern oder mit filigranen Formen das Problem auf, daß das bei der Produktion der Tabletten am Unterstempelschaft auftretende Drehmoment von den vorgenannten bekannten Unterstempeleinsätzen nicht mehr auf die Matrize übertragen werden kann, ohne daß die Unterstempeleinsätze hierbei brechen. Aus diesem Grund ist bei den bekannten Unterstempein eine Paßfeder vorgesehen, die in einer Unterstempelführung der Tablettiermaschine geführt wird und derart ein Verdrehen des Unterstempels und das damit einhergehende Drehmoment und/oder eine Biegebelastung des Unterstempels unterbindet. Eine Solche Tablettiermaschine ist vom Dokument DE 94 16 227 U bekannt.Such parts of a Tabtettierwericzeugs performing lower punches are known and are used in tabletting machines for the production of tablets. The lower punch insert of the lower punch acts in this case with a die which is fixedly arranged on the tableting machine. In the production of tablets, in particular in the production of pellets, by means of a Such Tablettierwerkzeugs occurs at Unterstempeleinsätzen with small diameters or with filigree shapes, the problem that the torque occurring in the production of the tablets on the lower punch shaft can no longer be transferred to the die of the aforementioned known Unterstempeleinsätzen without the Unterstempeleinsätze break here. For this reason, a feather key is provided in the known Unterstempein, which is guided in a lower punch guide of the tabletting and thus prevents twisting of the lower punch and the associated torque and / or bending load of the lower punch. Such a tabletting machine is known from document DE 94 16 227 U.
Eine Vielzahl von Tablettiermaschinen, insbesondere von im asiatischen Raum gebräuchlichen Tablettiermaschinen, weisen aber keine derartige Unterstempelführung auf, so daß es bei derartigen Maschinen in nachteiliger Art und Weise zur Zeit nicht möglich ist, empfindliche Unterstempeleinsätze oder Unterstempeleinsätze mit filigranen Formen und/oder geringem Durchmesser zu verwenden.However, a large number of tabletting machines, in particular tabletting machines customary in Asia, have no such bottom punch guide, so that it is currently not possible in such machines in a disadvantageous manner to provide delicate bottom punch inserts or bottom punch inserts with filigree shapes and / or small diameters use.
Es ist daher Aufgabe der vorliegenden Erfindung, einen Unterstempel der eingangs genannten Art derart weiterzubilden, daß auch bei einer Tablettiermaschine ohne Unterstempelführung Unterstempeleinsätze mit geringem Durchmesser und/oder mit einer filigranen Form verwendbar sind.It is therefore an object of the present invention to develop a lower punch of the type mentioned in such a way that even with a tableting without Unterstempelführung lower punch inserts with a small diameter and / or with a filigree shape can be used.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß der Unterstempelschaft eine außermittig angeordnete und in axialer Richtung verlaufende Führungsbohrung aufweist, in die ein Führungsstift eintaucht, der in einer mit dem Unterstempel zusammenwirkenden Matrize lagefixiert angeordnet ist, so daß der Führungsstift den sich auf- und abbewegenden Unterstempel während dieser Hubbewegung führt.This object is achieved in that the lower punch has an eccentrically arranged and extending in the axial direction of the guide bore, in which a guide pin is immersed, which is arranged fixed in position in a cooperating with the lower die die, so that the guide pin up and down moving lower punch during this stroke movement leads.
Durch die erfindungsgemäßen Maßnahmen wird in vorteilhafter Art und Weise ein Unterstempel für eine Tablettiermaschine, insbesondere eine Tablettierpresse, geschaffen, der in vorteilhafter Art und Weise auch in Tablettiermaschinen und insbesondere Tablettierpressen einsetzbar ist, die keine eigene Unterstempelführung aufweisen. Die erfindungsgemäßen Maßnahmen besitzen den Vorteil, daß die gesamte erfindungsgemäße Unterstempelführung, nämlich die im Inneren des Unterstempelschaftes angeordnete Führungsbohrung und der mit ihr zusammenwirkende Führungsstift, in radialer Richtung im wesentlichen vollständig im Inneren des Unterstempels angeordnet ist, so daß zur Aufnahme des erfindungsgemäßen Unterstempels in bekannte, keine eigene Unterstempelführung aufweisende Tablettiermaschinen keinerlei Umbaumaßnahmen erforderlich sind. Dies besitzt den Vorteil, daß in vorteilhafter Art und Weise auch bereits existierende, bekannte Tablettiermaschinen mit dem erfindungsgemäßen Unterstempel ausgerüstet werden können. Die erfindungsgemäße Ausführung des Unterstempels erlaubt es somit, auch bei derartigen bekannten Tablettiermaschinen ohne eigene Unterstempelführung nun Tablettierwerkzeuge, die empfindliche Einsätze aufweisen, zu verwenden.The inventive measures a lower punch for a tableting machine, in particular a tableting press, created in an advantageous manner, in an advantageous manner in tableting machines and in particular tabletting presses can be used which do not have their own lower punch guide. The measures according to the invention have the advantage that the entire invention Unterstempelführung, namely arranged in the interior of the lower punch shaft guide bore and cooperating with it guide pin, is disposed substantially completely in the interior of the lower punch in the radial direction, so that for receiving the lower punch according to the invention in known , no own Unterstempelführung having tableting machines no conversion measures are required. This has the advantage that in an advantageous manner also existing, known tableting machines can be equipped with the lower die according to the invention. The embodiment of the lower punch according to the invention thus makes it possible, even in such known tabletting without own Unterstempelführung now Tablettierwerkzeuge having sensitive inserts to use.
Eine vorteilhafte Weiterbildung der Erfindung sieht vor, daß in den Unterstempelschaft eine den mindestens einen Unterstempeleinsatz tragende Einsatzhalterung, insbesondere eine Unterstempellochplatte, eingesetzt ist, und daß diese Einsatzhalterung eine Durchtrittsöffnung für den den Unterstempelschaft führenden Führungsstift aufweist, welche im eingesetzten Zustand mit der Führungsbohrung des Unterstempelschafts fluchtet. Eine derartige Maßnahme besitzt den Vorteil, daß in den erfindungsgemäßen Unterstempeischaft des Unterstempels unterschiedliche Unterstempeleinsätze eingesetzt werden können, indem einfach die die Unterstempeleinsätze tragende Einsatzhalterung ausgetauscht wird.An advantageous development of the invention provides that in the lower ram a the at least one Unterstempeleinsatz bearing insert holder, in particular a Unterstempellochplatte is inserted, and that this insert holder has a passage opening for the leading punch shaft guide pin, which in the inserted state with the guide bore of the lower punch shaft flees. Such a measure has the advantage that in the Unterstempeischaft invention of the lower punch different Unterstempeleinsätze can be used by simply the supporting the Unterstempeleinsätze insert bracket is replaced.
Weitere vorteilhafte Weiterbildungen der Erfindung sind Gegenstand der Unteransprüche.Further advantageous developments of the invention are the subject of the dependent claims.
Weitere Einzelheiten und Vorteile der Erfindung sind dem Ausführungsbeispiel zu entnehmen, das im folgenden anhand der Figuren beschrieben wird. Es zeigen:
- Figur 1
- ein Ausführungsbeispiel des Unterstempels zusammen mit einer Matrize und einem Oberstempel, und
Figur 2- eine vergrößerte Darstellung des Unterstempels und der Matrize der Figur 1, teilweise im Schnitt.
- FIG. 1
- an embodiment of the lower punch together with a die and an upper punch, and
- FIG. 2
- an enlarged view of the lower punch and the die of Figure 1, partially in section.
In Figur 1 ist nun ein an und für sich bekanntes und daher nur auszugweise beschriebenes Tabtettierwerkzeug 1 dargestellt, welches sich in bekannter Art und Weise in einen Oberstempel 2, einen Unterstempel 3 und eine Matrize 4 gliedert. Die Matrize 4 ist wiederum in an und für sich bekannter Art und Weise fest in einer nicht gezeigten, das Tablettierwerkzeug 1 verwendenden Tablettiermaschine befestigt, während sich der Oberstempel 2 und der Unterstempel 3 während des Herstellvorgangs von Tabletten, Pellets oder ähnlicher Komprimate auf- und abbewegen. Hierzu ist vorgesehen, daß der Unterstempel 3 und der Oberstempel 2 in entsprechenden Führungen der Tablettiermaschine angeordnet sind, wobei der Oberstempel 2 im hier gezeigten Fall eine Paßfeder 2' aufweist, die mit der Oberstempelführung der Tablettiermaschine zusammenwirkt und verhindert, daß beim Herstellungsvorgang ein Drehmoment und/oder eine Biegebelastung auftreten können, welche dazu führen würden, daß der oder die Oberstempeleinsätze 2a des Oberstempels 2, von denen in der Figur 1 nur ein einziger gezeigt ist, beschädigt würden.In FIG. 1, a tabtaking tool 1 which is known per se and therefore only described in detail is shown, which is divided in a known manner into an
Da - wie bereits eingangs erwähnt - eine Vielzahl von Tablettiermaschinen keine ein Verdrehen des Unterstempels 3 verhindemde eigene Unterstempelführung aufweisen, war es bisher bei derartigen Maschinen nicht möglich, Unterstempel 3 mit ein oder mehreren Unterstempeleinsätzen 6, von denen in den Figuren 1 und 2 wiederum nur ein einziger gezeigt ist, zu verwenden. Um es jedoch auch bei derartigen Tablettiermaschinen zu ermöglichen, Unterstempel 3 mit empfindlichen Unterstempeleinsätzen 6 zu verwenden, ist bei dem beschriebenen Ausführungsbeispiel des Unterstempels 3 vorgesehen, daß im Unterstempelschaft 10 des Unterstempels 3 des Tablettierwerkzeugs 1 eine exzentrisch angeordnete und in axialer Richtung A des Unterstempels 3 verlaufende Führungsbohrung 11 vorgesehen ist, in die ein Führungsstift 12 eintaucht, der - wie insbesondere aus Figur 2 ersichtlich ist - in der Matrize 4 fixiert ist. Der Unterstempelschaft 10 des Unterstempels 3 wird somit bei einer Auf- und Abbewegung durch den in der Matrize 4 fixierten Führungsstift 12 geführt, so daß ein "Ausnicken" des die Unterstempeleinsätze 6 tragenden Unterstempelschafts 10, welches zu einer unerwünschten Biegebelastung der Unterstempeleinsätze 6 führen würde, verhindert oder ihm zumindest entgegengewirkt wird. Die exzentrische, also außermittige Anordnung der Führungsbohrung 11 bewirkt im Zusammenwirken mit dem an der Matrize 4 fixierten Führungsstift 12, daß - da die Matrize 4 ihrerseits fest mit der Tablettiermaschine verbunden ist - der Unterstempelschaft 10 sich bei der Auf- und Abbewegung nicht verdrehen kann, also keine Drehbewegung um seine Achse ausführen kann, so daß das Auftreten einer Drehmomentbelastung, hervorgerufen durch eine Verdrehung um die Achse des Unterstempelschafts 10, an den Unterstempeleinsätzen 6 verhindert wird.Since - as already mentioned - a variety of tabletting machines have no twisting the
Wie am besten aus Figur 2 ersichtlich ist, ist bei dem beschriebenen Ausführungsbeispiel des Unterstempels 3 vorgesehen, daß die in Bohrungen 4b der Matrize 4 eintauchenden Unterstempeleinsätze 6 nicht unmittelbar am Unterstempelschaft 10 angeordnet sind, sondern auf einer - hier als Unterstempellochplatte 7 ausgebildeten - Einsatzhalterung 8 angeordnet sind, die ihrerseits am Unterstempelschaft 10 befestigt ist. Hierbei ist vorgesehen, daß der Unterstempelschaft 10 eine Aufnahmebohrung 10a aufweist, in die ein Führungseinsatz 7a der Unterstempellochplatte 7 eingreift, welcher durch geeignete Mittel im Unterstempelschaft 10 fixiert ist.As best seen in Figure 2, it is provided in the described embodiment of the
Die Unterstempellochplatte 7 weist hierbei eine Durchtrittsöffnung 14 für den Führungsstift 12 auf, welche fluchtend zu der eine Entlüftungsöffnung 18 aufweisenden Führungsbohrung 11 des Unterstempelschafts 10 angeordnet ist, so daß der Führungsstift 12 durch die Durchtrittsöffnung 14 in die Führungsbohrung 11 des Unterstempelschafts 10 einschiebbar ist.The Unterstempellochplatte 7 in this case has a passage opening 14 for the
Der Vollständigkeit halber soll noch erwähnt werden, daß bevorzugt wird, daß der Führungsstift 12 in der Matrize 4 in einer Aufnahmebohrung 16 aufgenommen gelagert ist und mittels eines Arretierelements 17 in der Matrize 4 lagefixiert ist. Es ist aber auch grundsätzlich möglich, daß der Führungsstift 12 als ein integraler Bestandteil der Matrize 4 ausgebildet ist, wobei aber die erstgenannte Ausbildungsmöglichkeit bevorzugt wird, da hierdurch in einfacher Art und Weise ein Austauschen des Führungsstifts 12, z. b. bei einem Defekt, ermöglicht wird und außerdem auch bekannte, bereits vorhandene Matrizen leicht nachgerüstet werden können, indem in sie die Aufnahmebohrung 16 eingebracht wird.For completeness, it should be mentioned that it is preferred that the
Zusammenfassend ist festzuhalten, daß es die beschriebenen Maßnahmen in vorteilhafter Art und Weise ermöglichen, auch bei bereits vorhandenen Tablettiermaschinen, die über keine eigene Unterstempelführung verfügen, nunmehr Unterstempel mit empfindlichen Unterstempeleinsätzen zu verwenden, was in nachteiliger Art und Weise bis jetzt nicht möglich war. Da die gesamten technischen Maßnahmen innerhalb des Unterstempelschafts 10 angeordnet sind, ist es in vorteilhafter Art und Weise nicht erforderlich, daß bei den bekannten Tablettiermaschinen Umrüstungsmaßnahmen im Bereich ihrer Unterstempelführungen durchgeführt werden müssen.In summary, it should be noted that allow the described measures in an advantageous manner, even with existing tableting machines that have no own Unterstempelführung now use lower punch with sensitive lower punch inserts, which was not possible in a disadvantageous manner until now. Since the entire technical measures are arranged within the lower punch shaft 10, it is advantageously not necessary that in the known tabletting equipment retrofitting measures in the area of their lower punch guides must be performed.
