Die oben gemachten Ausführungen zu der Vorrichtung und zu dem System gelten für das erfindungsgemäße Verfahren gleichermaßen.The statements made above about the device and the system apply equally to the method according to the invention.
Vorzugsweise werden die Rohlinge in die Einbuchtungen gedrückt. Dies erfolgt besonders bevorzugt und bewirkt, dass sich der Rohling hinreichend weit und schnell genug in die Einbuchtung einlegt und nicht zu weit aus dieser Heraussteht, was zu einer Beschädigung des Tablettenrohlings führen könnte. Das Drücken der Tablette erfolgt wie oben beschrieben beispielsweise mit einem Beschleunigungsrad.Preferably, the blanks are pressed into the recesses. This is particularly preferred and causes the blank sufficiently far and quickly enough in the indentation and not too far out of this protruding, which could lead to damage of the tablet blank. The pressing of the tablet is carried out as described above, for example with an accelerator.
Vorzugsweise werden die Rohlinge in dem Ausgangsbereich von einem Auswerfer aus den Einbuchtungen in die Matrize der Tablettenpresse gedrückt wird.Preferably, the blanks are pressed in the exit region of an ejector from the indentations in the mold of the tablet press.
Vorzugsweise wird die Drehung der Scheibe und der Matrizen synchronisiert. Dafür wird die Drehung der Scheibe besonders bevorzugt mechanisch von der Drehbewegung der Tablettenpresse abgeleitet.Preferably, the rotation of the disc and the dies is synchronized. For this purpose, the rotation of the disc is particularly preferably derived mechanically from the rotational movement of the tablet press.
Im Folgenden wird die Erfindung anhand der Figuren 1 bis 6 erläutert. Diese Erläuterungen sind lediglich beispielhaft und schränken den allgemeinen Erfindungsgedanken nicht ein. Die Erläuterungen gelten für alle Gegenstände der Erfindung gleichermaßen.The invention will be explained below with reference to FIGS. 1 to 6.

In Figur 1 ist das erfindungsgemäße System dargestellt. Dieses weist die erfindungsgemäße Vorrichtung 1 sowie eine nur teilweise dargestellte Tablettenpresse 4 auf. Über eine Rinne 15 werden Tablettenrohlinge 2, die in dem vorliegenden Fall im Wesentlichen zylindrisch sind, auf Stoß in Richtung der Scheibe 5 transportiert und dort vereinzelt. Um einen kontinuierlichen Strom von Tablettenrohlingen 2 zu erzielen und um sicherzustellen, dass diese mit einem gewissen Druck in Richtung der Scheibe 5 gefördert werden, weist die erfindungsgemäße Vorrichtung 1 ein Beschleunigungsmittel 14, in dem vorliegenden Fall eine angetriebene Scheibe auf, die die Rohlinge in Richtung der Scheibe 5 drückt. Die Scheibe 5 dreht sich im Uhrzeigersinn und weist an ihrem Umfang 6, wie insbesondere in Figur 4 deutlich zu erkennen ist, Einbuchtungen 7 auf. In diesen Einbuchtungen 7 werden die Tablettenrohlinge 2 einzeln aufgenommen und im Uhrzeigersinn zu der Tablettenpresse 4 transportiert, die eine Vielzahl von Matrices 3 aufweist und sich gegen den Uhrzeigersinn dreht. In diese Matrices 3 werden die Tablettenrohlinge eingelegt. Dafür weist die erfindungsgemäße Vorrichtung eine Vielzahl von Auswerfern 9 auf, die sich oberhalb der Einbuchtung befinden und die sich mit diesen synchron im Uhrzeigersinn drehen. Im Bereich der Matrices 3 drücken diese Auswerfer 9 die Tablettenrohlinge 2 aus den Einbuchtungen 7 nach unten, so dass sie in die Matrices 3 gedrückt werden und/oder in diese durch die Schwerkraft hineinfallen. Um zu verhindern, dass die Tablettenrohlinge 2 durch die Zentrifugalkraft aus den Einbuchtungen 7 herausgeschleudert werden, weist die erfindungsgemäße Vorrichtung eine äußere Rohlingsführung 8 auf, an die sich ein Drucksegment 13 anschließt. Dieses Drucksegment 13 ist drehbar um eine Drehachse 18 senkrecht zur Papierebene an der äußeren Rohlingsführung 8 gelagert und in Richtung der Scheibe 5 vorgespannt. Durch dieses variable Drucksegment 13 ist sichergestellt, dass die Tabletten, während der Übergabe von der Einbuchtung 7 in die Matrize 3, in die Einbuchtung 3 hineingedrückt ist und dadurch besonders gut mit der darunterliegenden Matrize 3 fluchtet.FIG. 1 shows the system according to the invention. This comprises the device 1 according to the invention and a tablet press 4 only partially shown. About a groove 15 tablet blanks 2, which are substantially cylindrical in the present case, transported in shock in the direction of the disc 5 and separated there. In order to obtain a continuous stream of tablet blanks 2 and to ensure that they are conveyed with a certain pressure in the direction of the disc 5, the device 1 according to the invention comprises an accelerating means 14, in the present case a driven disc, which moves the blanks in the direction the disc 5 presses. The disc 5 rotates clockwise and has recesses 7 on its circumference 6, as can be clearly seen in particular in FIG. In these recesses 7, the tablet blanks 2 are individually picked up and transported in a clockwise direction to the tablet press 4, which has a plurality of matrices 3 and rotates counterclockwise. In these matrices 3 are the Tablet blanks inserted. For this, the device according to the invention on a plurality of ejectors 9, which are located above the indentation and rotate synchronously with them in a clockwise direction. In the area of the matrices 3, these ejectors 9 push the tablet blanks 2 downwards from the indentations 7, so that they are pressed into the matrices 3 and / or fall into them by gravity. In order to prevent the tablet blanks 2 from being ejected out of the indentations 7 by the centrifugal force, the device according to the invention has an outer blank guide 8, to which a pressure segment 13 adjoins. This pressure segment 13 is rotatably mounted about an axis of rotation 18 perpendicular to the plane of the paper on the outer blank guide 8 and biased in the direction of the disc 5. By this variable pressure segment 13 ensures that the tablets, during the transfer of the indentation 7 in the die 3, is pressed into the recess 3 and thereby particularly well aligned with the underlying die 3.
In Figur 2 ist die erfindungsgemäße Vorrichtung noch einmal im Detail dargestellt. Wie bereits beschrieben, werden die Tablettenrohlinge (in dem vorliegenden Fall nicht dargestellt) von rechts nach links entlang einer Rinne gefördert und durch die Scheibe 14, die von oben durch einen Schlitz in die Rinne hineinragt, in Richtung der Scheibe 5 gefördert bzw. gedrückt. Die Scheibe 14 ist motorisch angetrieben und weist an ihrem Umfang eine Gummierung auf, die einen besonders guten Reibschluss zwischen den Tablettenrohlingen und der Scheibe 14 bewirkt und verhindert, dass die Rohlinge beschädigt werden. Die Scheibe 5 rotiert, wie durch den Pfeil dargestellt, im Uhrzeigersinn. Sobald eine Einbuchtung 7 an dem Eingangsbereich 10 vorbei rotiert, wird ein Rohling aufgrund des von der Scheibe 14 erzeugten Drucks in eine Einbuchtung hineingedrückt und von der Scheibe weiter transportiert. Um zu vermeiden, dass der Rohling beim Transport durch Auftreten der Zentrifugalkräfte wieder aus der Einbuchtung 7 herausgedrückt wird, weist die erfindungsgemäße Vorrichtung 1 eine äußere Rohlingsführung 8 auf, die an ihrem Ende in das bereits in Figur 1 beschriebene variable Drucksegment 13 mündet. Dieses Drucksegment 13 befindet sich im Ausgangsbereich 11 der erfindungsgemäßen Vorrichtung, in dem die Tablettenrohlinge 2 an die jeweilige Matrize 3 übergeben werden. Die so entleerte Einbuchtung 7 rotiert dann wieder in den Eingangsbereich 10 und wird erneut mit einem Tablettenrohling 2 bestückt. Figur 3 zeigt die Vorrichtung gemäß den Figuren 1 und 2 im Schnitt. Deutlich zu erkennen ist die Scheibe 5 mit den am Umfang angeordneten Einbuchtungen 7. Unterhalb der Scheibe 5 ist eine Verteilscheibe 10 angeordnet, die sich vom Eingangsbereich 10 bis kurz vor den Ausgangsbereich 11 erstreckt und verhindert, dass die Tablettenrohlinge nach unten aus der Scheibe 5 herausfallen. Im Ausgangsbereich ist diese Verteilscheibe 10 nicht vorhanden, damit der Tablettenrohling wie weiter unten beschrieben nach unten in die Matrize 3 gedrückt werden kann. Oberhalb jeder Einbuchtung 7 ist ein Auswerfer 9 angeordnet, der mit zwei flexiblen Metallstreifen 16 an einer Drehachse aufgehängt ist. Im Ausgangsbereich 11 ist ein ortsfester Aktuator, in dem vorliegenden Fall ein Kugellager, angeordnet, das den Auswerfer 9, sobald er an dem ortsfesten Kugellager 17 vorbei rotiert, nach unten drückt. Dadurch wird der Vorsprung an dem Auswerfer ebenfalls nach unten gedrückt und schiebt den Tablettenrohling aus der Einbuchtung 7 in Richtung der Matrize 3 und/oder in die Matrize 3 hinein. Sobald der Auswerfer 9 an dem Aktuator 17 vorbei rotiert ist, springt er aufgrund der Spannung der Aufhängung 16 in seine ursprüngliche Stellung zurück.In Figure 2, the inventive device is shown again in detail. As already described, the tablet blanks (not shown in the present case) are conveyed from right to left along a groove and conveyed in the direction of the disc 5 by the disc 14, which protrudes from above through a slot in the groove. The disc 14 is driven by a motor and has on its periphery a rubber coating, which causes a particularly good frictional engagement between the tablet blanks and the disc 14 and prevents the blanks are damaged. The disc 5 rotates, as shown by the arrow, in a clockwise direction. As soon as an indentation 7 rotates past the input region 10, a blank is pressed into a recess due to the pressure generated by the disc 14 and transported further by the disc. In order to avoid that the blank is pushed out of the recess 7 during transport by the occurrence of centrifugal forces, the device 1 according to the invention has an outer blank guide 8, which opens at its end into the variable pressure segment 13 already described in FIG. This pressure segment 13 is located in the exit region 11 of the device according to the invention, in which the tablet blanks 2 are transferred to the respective die 3. The thus emptied indentation 7 then rotates again into the input area 10 and is again equipped with a tablet blank 2. FIG. 3 shows the device according to FIGS. 1 and 2 in section. Clearly visible is the disc 5 with the recesses 7 arranged on the circumference. Disposed below the disc 5 is a distribution disc 10 which extends from the entry region 10 to just before the exit region 11 and prevents the tablet blanks from falling out of the disc 5 , In the exit region, this distribution disc 10 is not present, so that the tablet blank can be pressed down into the die 3 as described below. Above each indentation 7, an ejector 9 is arranged, which is suspended with two flexible metal strips 16 on a rotation axis. In the exit region 11 is a stationary actuator, in the present case, a ball bearing, arranged, which presses the ejector 9, as soon as it rotates past the stationary ball bearing 17 down. As a result, the projection on the ejector is also pressed down and pushes the tablet blank out of the indentation 7 in the direction of the die 3 and / or into the die 3. Once the ejector 9 is rotated past the actuator 17, it jumps back to its original position due to the tension of the suspension 16.
Figur 4 zeigt Details der Scheibe 5, die an ihrem Umfang 6 eine Vielzahl von Einbuchtungen 7 aufweist, in die die Tablettenrohlinge eingelegt werden können. Es ist deutlich zu erkennen, dass die Einbuchtungen 7 der Form der Rohlinge 2 angepasst sind, so dass diese so in der Einbuchtung anliegen, dass ihre Lage eindeutig festgelegt ist. Vorzugsweise liegt der Tablettenrohling am Fuß und zumindest an einer Seitenwand der Einbuchtung an. Die Einbuchtung 7 ist so gestaltet, dass nur ein Tablettenrohling darin Platz findet. Desweiteren ist zu erkennen, dass die Einbuchtungen 7, bezogen auf die durch den Fall dargestellte Rotationsrichtung, vor den Einbuchtungen jeweils einen Einlaufbereich 7'aufweisen. Dieser Einlaufbereich 7'erleichtert das Einführen der Tablettenrohlinge 2 in die Einbuchtungen 7.Figure 4 shows details of the disc 5, which has at its periphery 6 a plurality of indentations 7, in which the tablet blanks can be inserted. It can be clearly seen that the recesses 7 are adapted to the shape of the blanks 2, so that they rest in the indentation so that their position is clearly defined. Preferably, the tablet blank rests against the foot and at least on a side wall of the indentation. The indentation 7 is designed so that only a tablet blank can fit into it. Furthermore, it can be seen that the indentations 7, relative to the direction of rotation represented by the case, each have an inlet region 7 ' in front of the indentations. This inlet region 7 ' facilitates the insertion of the tablet blanks 2 into the indentations 7.
Figur 5 zeigt nochmals eine Darstellung der erfindungsgemäßen Vorrichtung 1. Diese Darstellung entspricht im Wesentlichen der Darstellung gemäß Figur 2, wobei in dem vorliegenden Fall noch die Auswerfer 9 oberhalb der Einbuchtungen 7 dargestellt sind. Es ist zu erkennen, dass jeder Einbuchtung 7 ein Auswerfer 9 zugeordnet ist. Desweiteren ist der Eingangsbereich 10 relativ zum Ausgangsbereich 11 dargestellt. Es ist zu erkennen, dass die Tablettenrohlinge 2 vom Eingangsbereich zum Ausgangsbereich im Wesentlichen eine Drehung um 270° durchführen. In dem vorliegenden Fall wird die Drehung der Scheibe im Uhrzeigersinn von einer Drehung der Matrices 4 gegen den Uhrzeigersinn von der Tablettenpresse abgeleitet. Es ist deshalb vorteilhaft, wenn die Anzahl der Einbuchtungen 7 am Umfang 6 der Scheibe 5 mit der Anzahl der Matrices in der Tablettenpresse, übereinstimmt.FIG. 5 again shows a representation of the device 1 according to the invention. This representation substantially corresponds to the representation according to FIG. 2, wherein in the present case the ejectors 9 are still shown above the indentations 7. It can be seen that each indentation 7 is an ejector 9 assigned. Furthermore, the input area 10 is shown relative to the output area 11. It can be seen that the tablet blanks 2 essentially make a rotation of 270 ° from the entrance area to the exit area. In the present case, the clockwise rotation of the disc is derived from a rotation of the matrices 4 counterclockwise from the tablet press. It is therefore advantageous if the number of indentations 7 on the circumference 6 of the disc 5 coincides with the number of matrices in the tablet press.
Figur 6 zeigt schematisch die Tablettenpresse 4. Diese weist eine Vielzahl von Matrices 3 auf, die in dem vorliegenden Fall gegen den Uhrzeigersinn rotieren und in die ein Tablettenrohling 2 eingeführt wird. Oberhalb und unterhalb jeder Matrize 3 ist je ein Stempel 15 vertikal verschiebbar angeordnet, der jeweils durch eine Kurve bzw. durch rotierende Räder in seiner Lage veränderbar ist. Durch eine Lageveränderung in Richtung des Tablettenrohlings wird dieser in die gewünschte Form gepresst. Sobald dies erfolgt ist, wird der obere Stempel wieder nach ober verfahren und gleichzeitig wirft der untere Stempel durch eine nach oben gerichtete Bewegung die fertiggestellte Tablette aus der Matrize 3 aus, die sodann aus der Tablettenpresse 4 entfernt wird, so dass der gesamte Vorgang von neuem beginnen kann. Die Bewegungsrichtung der Matrices bzw. der Stempel ist durch die beiden Pfeile in Figur 6 dargestellt. Die erfindungsgemäße Vorrichtung legt die Tablettenrohlinge 2 in die Matrices 3 ein. Figure 6 schematically shows the tablet press 4. This has a plurality of matrices 3, which rotate in the present case counterclockwise and into which a tablet blank 2 is introduced. Above and below each die 3 each a punch 15 is arranged vertically displaceable, which is variable in each case by a curve or by rotating wheels in position. By a change in position in the direction of the tablet blank this is pressed into the desired shape. Once this is done, the upper punch is moved back up and at the same time raises the lower punch by an upward movement of the completed tablet from the die 3, which is then removed from the tablet press 4, so that the whole process again can start. The direction of movement of the matrices or the stamp is represented by the two arrows in FIG. The device according to the invention places the tablet blanks 2 in the matrices 3.
