Description

Die Erfindung bezieht sich auf eine Vorrichtung nach dem Obebegriff vom Anspruch 1The invention relates to a device according to the general concept of claim 1

Moderne Tablettiermaschinen sind geeignet, Tabletten verschiedener Arten und Formen zu verpressen. Bei kreissymmetrischen Tabletten ist die Justierung der einzelnen Matrizen zu den Ober- und Unterstempeln nicht erforderlich. Wenn eine kreissymmetrische Tablette auf beiden Seiten beschriftet werden oder beidseitig Sollbruch-Kerben aufweisen soll, so ist die Justierung von Ober- und Unterstempeln zueinander wichtig. Dies erfolgt bisher mittels mit Nuten versehener Führungsbuchsen für die Ober- und Unterstempel. Die Justierung der Matrize mit kreissymmetrischer Bohrung zu den Stempeln ist nicht notwendig. Modern tableting machines are suitable for tablets different types and shapes. At circular symmetrical tablets is the adjustment of the individual matrices for the upper and lower punches not mandatory. If a circular symmetry Tablet to be labeled on both sides or should have predetermined breaking notches on both sides the adjustment of upper and lower punches to each other important. So far, this has been done by means of grooved Guide bushes for the upper and lower punches. Adjustment of the die with circular symmetry Drilling to the stamps is not necessary.

Wenn die Tablettenform nicht kreissymmetrisch ausgeführt ist, werden sogenannte Facon-Matrizen benötigt und die alleinige Justierung von Ober- und Unterstempeln zueinander ist nicht ausreichend. Facon-Matrizen sind am Außenumfang kreiszylindrische Matrizen, deren Formmulde nicht rotationssymmetrisch sondern asymmetrisch zur Matrizenachse ausgerichtet ist. Um asymmetrische Tabletten in Formmulden herstellen zu können, müssen die Ober- und Unterstempel zueinander und zur Formmulde der Facon-Matrize justiert sein.If the tablet shape is not circularly symmetrical so-called Facon matrices are required and the sole adjustment of upper and lower punches to each other is not enough. Facon matrices are circular cylindrical matrices on the outer circumference The mold trough is not rotationally symmetrical but asymmetrical is aligned with the die axis. To asymmetrical Manufacture tablets in mold cavities the upper and lower stamps must be in relation to each other and be adjusted to the mold cavity of the Facon matrix.

Bei den herkömmlichen Vorrichtungen zur Fixierung von Facon-Matrizen wird zunächst ein oberes Kurvensegment im Kurvenablauf für die Oberstempel demontiert. Danach wird der Oberstempel durch die obere Führungsbuchse des Rotors der Tablettiermaschine geführt. Anschliessend wird die Facon-Matrize mittels des Oberstempels in die Matrizenbohrung des Matrizentisches gedrückt. Der Oberstempel und die Facon-Matrize sind somit zueinander justiert. Während der Oberstempel die Facon-Matrize festhält, wird diese mittels der zugehörigen Matrizenhalter befestigt. Danach wird der Oberstempel zur Kontrolle wieder hoch- und heruntergefahren, wobei die Matrizenwand der Facon-Matrize nicht berührt werden sollte. Dabei wird kontrolliert, ob der Oberstempel und die Facon-Matrize noch richtig zueinander justiert sind. So kann sich die Facon-Matrize während der Befestigung mit den Matrizenhaltern tangential verschieben. In diesem Falle muß der gesamte Fixierungsvorgang wiederholt werden. Ähnliches gilt, wenn der Oberstempel zur Kontrolle während des erneuten Herunterfahrens des Oberstempels die Facon-Matrize berührt. Die Fixierung der Facon-Matrizen zu den Oberstempeln ist gleichbedeutend mit der Fixierung der Facon-Matrizen zu den Unterstempeln, da diese - bedingt durch die jeweiligen Führungsbuchsen und deren Nuten - zu den Oberstempeln ausgerichtet sind. Diese mühevolle und zeitaufwendige Fixierung der Facon-Matrizen zu den Oberstempeln ist gleichbedeutend mit Maschinenstillstandszeiten. Da jedoch moderne Tablettiermaschinen einen hohen Investitionswert haben, müssen kurze Stillstandszeiten erreicht werden.In the conventional devices for fixing Facon matrices initially become an upper curve segment disassembled in the curve for the upper stamp. After that the upper punch is through the upper guide bush the rotor of the tabletting machine. Subsequently the Facon die is made using the upper stamp pressed into the die hole of the die table. The upper stamp and the Facon die are thus mutually related adjusted. The Facon die during the upper stamp holds, this is done by means of the associated Die holder attached. Then the upper stamp to control up and down again, whereby do not touch the matrix wall of the Facon matrix should. It is checked whether the upper stamp and the Facon matrix is still correct to each other are adjusted. This is how the Facon matrix can be during the attachment with the die holders tangential move. In this case, the entire fixation process be repeated. The same applies if the upper stamp for checking during the renewed Shutting down the upper die, the Facon die touched. The fixation of the Facon matrices to the upper punches is synonymous with the fixation of the Facon matrices to the lower stamps, as these - conditionally through the respective guide bushings and their grooves - are aligned with the upper stamps. This arduous and time-consuming fixation of the Facon matrices to the Top stamping is synonymous with machine downtime. However, since modern tableting machines have a high investment value, short must Downtimes can be achieved.

Der Erfindung liegt daher die Aufgabe zugrunde, eine Vorrichtung zu schaffen, mit der die Facon-Matrizen zu den Oberstempeln in einfacher Weise fixierbar sind.The invention is therefore based on the object To create device with which the Facon matrices to the upper stamps can be fixed in a simple manner.

Die Lösung dieser Aufgabe ergibt sich aus den kennzeichnenden Merkmalen des Patentanspruches 1. Durch die Verwendung von Facon-Matrizen mit der Formmulde zugeordneten Zentrierflächen können diese mit einem Zentrierstück zu den Oberstempeln der Tablettiermaschine in einfacher Weise fixiert werden, wodurch sich die Maschinenstillstandszeiten beim Auswechseln der Facon-Matrizen stark verkürzen. Dabei sind die Zentrierstücke lösbar bzw. bewegbar, insbesondere axial oder vertikal verschiebbar gelagert, so daß auch runde Standardmatrizen anstelle der Facon-Matrizen verwendbar sind. Weitere vorteilhafte Ausgestaltungen der Erfindung ergeben sich aus den Unteransprüchen.The solution to this problem follows from the characteristic ones Features of claim 1. By the use of Facon matrices with the mold trough assigned centering surfaces can be marked with a Centering piece for the upper punches of the tableting machine be fixed in a simple manner, whereby the machine downtimes when changing shorten the Facon matrices. Here are the Centering pieces detachable or movable, in particular axially or vertically displaceable, so that also standard round matrices instead of Facon matrices are usable. Further advantageous configurations the invention emerge from the subclaims.
