Abstract

The press has a press station, a filling device and a rotor (10) that is provided with an annular surface (36) radially outside a pitch circle for cavity holes of a cavity plate (12). The surface (36) extends horizontally and is concentric to an axis of rotation of the rotor. The surface is lowered opposite to a top side of the plate (12) around a preset measure which corresponds to thickness of pellets. A baffle plate (38) guides the pellets that are ejected from the holes to the surface (36). A redirecting section (42) guides the pellets from the surface outside to a discharge channel.

Description

Die Erfindung bezieht sich auf eine Rundläuferpresse nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a rotary press according to the preamble of patent claim 1.

Rundläuferpressen zur Herstellung von Tabletten und anderen Preßlingen sind seit langem bekannt. Sie weisen generell einen um eine vertikale Drehachse drehend antreibbaren Rotor auf, der eine Matrizenscheibe mit auf einem Teilkreis angeordneten Matrizenbohrungen aufweist sowie Unter- und Oberstempel und Führungen dafür. Zur Rundläuferpresse gehören ferner Steuerkurven für Ober- und Unterstempel sowie mindestens eine Preßstation mit oberer und unterer Druckrolle. Ferner ist eine derartige Rundläuferpresse mit einer Fülleinrichtung ausgestattet, die automatisch zu verpressendes Material in die Matrizenbohrungen einfüllt sowie einem Abstreifer, der von den Unterstempeln ausgestoßene Preßlinge von der Oberseite der Matrizenscheibe abstreift in einen Ablaufkanal hinein. Am Ende des Ablaufkanals befindet sich eine Abfülleinrichtung. Wahlweise können die Preßlinge auch zu einer Prüfstation gelenkt werden.Rotary presses for the production of tablets and other compacts have long been known. They generally have a rotatably driven about a vertical axis of rotation rotor having a die plate with arranged on a pitch circle die holes and lower and upper punches and guides for it. The rotary press also includes cams for upper and lower punches and at least one pressing station with upper and lower pressure roller. Furthermore, such a rotary press is equipped with a filling device which automatically fills material to be pressed in the die holes and a scraper, which strips the ejected from the lower punches pressed bricks from the top of the die plate into a drainage channel. At the end of the drainage channel is a filling device. Optionally, the compacts can also be directed to a testing station.

Das Abstreifen von Preßlingen im Betrieb einer derartigen Rundläuferpresse muß im bekannten Fall zwischen der - jeweils letzten - Preßstation und der Füllvorrichtung erfolgen. In der Füllvorrichtung wird die Wiederauffüllung der Matrizenbohrungen vorgenommen. Bei einer Doppel-Rundläuferpresse sind daher Abstreifer auf annähernd gegenüberliegenden Seiten vorgesehen. Daher ist entsprechender Platz für die Entfernung der Preßlinge vorzusehen, der mitunter nicht vorhanden ist.The stripping of compacts in the operation of such a rotary press must be done in the known case between the - last - pressing station and the filling device. In the filling device, the replenishment of the die holes is made. In a double rotary press therefore scrapers are provided on approximately opposite sides. Therefore, appropriate space for the removal of the compacts is provided, which is sometimes not available.

Der Erfindung liegt die Aufgabe zugrunde, eine Rundläuferpresse zu schaffen, in der die Preßlinge an einem gewünschten Ort am Umfang des Rotors entnommen werden können.The invention has for its object to provide a rotary press in which the compacts can be removed at a desired location on the circumference of the rotor.

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

Bei der erfindungsgemäßen Rundläuferpresse ist der Rotor radial außerhalb des Teilkreises für die Matrizenbohrungen mit einer Ringfläche versehen, die sich vorzugsweise horizontal erstreckt und die konzentrisch ist zur Drehachse des Rotors. Die Ringfläche ist gegenüber der Oberseite der Matrizenscheibe um ein vorgegebenes Maß abgesenkt. Erste Ablenkmittel lenken die aus den Matrizenbohrungen ausgestoßenen Preßlinge zur Ringfläche hin, und zweite Ablenkmittel lenken die Preßlinge von der Ringfläche nach außen zu einem Abführkanal.In the rotary press according to the invention, the rotor is provided radially outside the pitch circle for the die holes with an annular surface which preferably extends horizontally and which is concentric with the axis of rotation of the rotor. The annular surface is lowered relative to the top of the die plate by a predetermined amount. First deflection means deflect the compacts ejected from the die bores towards the annular surface, and second deflection means deflect the compacts outwardly from the annular surface to a discharge channel.

Sobald bei der erfindungsgemäßen Rundläuferpresse der Preßling auf die niedrigere Ringfläche gelenkt ist, kann sie sich unbehelligt durch eine Preßstation oder Füllvorrichtung bewegen und dann mit Hilfe des zweiten Abstreifmittels an einem gewünschten Ort nach außen geführt werden. Somit hat die erfindungsgemäße Rundläuferpresse den Vorteil, daß die Preßlinge an beliebigen Stellen unabhängig von ihren Prozeßeinrichtungen in Abläufe überführt werden können. Ein besonderer Antrieb ist hierfür nicht erforderlich.Once in the rotary press according to the invention, the compact is directed to the lower annular surface, it can move unmolested by a pressing station or filling device and then out with the help of the second stripping means at a desired location to the outside. Thus, the rotary press according to the invention has the advantage that the compacts can be converted at any point regardless of their process facilities in processes. A special drive is not required for this.

Die Erfindung ist insbesondere für Mehrfach-Rundläuferpressen von Vorteil, weil dadurch das Abführen der Preßlinge an nur einem Ort am Umfang des Rotors vorgenommen werden kann. Peripheriegeräte sind daher nur an einer Seite der Presse notwendig. Der Raumbedarf für die Aufstellung der erfindungsgemäßen Rundläuferpresse, für die Peripheriegeräte und möglicherweise einen Container bei der Anwendung eines Preßlingscontainers ist minimal.The invention is particularly advantageous for multiple rotary presses, because thereby the removal of the compacts can be made at only one location on the circumference of the rotor. Peripheral devices are therefore only necessary on one side of the press. The space required for the installation of the rotary press according to the invention, for the peripherals and possibly a container in the application of a compact container is minimal.

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

zeigt den Rotor nach Figur 1 in perspektivischer Darstellung ohne die Preß-stationen.
An embodiment of the invention will be explained in more detail with reference to drawings.
Fig. 1
shows the schematic plan view of the rotor of a double rotary press.
Fig. 2
shows the rotor of Figure 1 in perspective view without the pressing stations.

In den Figuren 1 und 2 ist ein Rotor 10 einer Doppel-Rundläuferpresse gezeigt, welche nur in Andeutungen wiedergegeben ist. Der Rotor ist um eine vertikale Achse (in Fig. 1 senkrecht zur Zeichenebene) mit Hilfe eines Drehantriebs drehend antreibbar. Zum Rotor 10 gehören Ober- und Unterstempel, die in Stempelführungen geführt sind. Beides ist ebenfalls nicht gezeichnet. Der Rotor weist eine Matrizenscheibe 12 auf, die auf einem Teilkreis 14 eine Reihe von Matrizenbohrungen aufweist. Die Matrizenbohrungen sind nicht gezeigt, sondern lediglich die Preßlinge, die im vorliegenden Ausführungsbeispiel rechteckig geformt sind. Dem Rotor 10 ist eine erste Füllvorrichtung 16 zugeordnet, mit deren Hilfe zu verpressendes Pulver in die Matrizenbohrungen eingefüllt wird. Der Rotor dreht sich im Ausführungsbeispiel entgegengesetzt der Uhrzeigerrichtung. In Drehrichtung sind dem Rotor 10 danach eine Vorpreßstation 18 und eine Hauptpreßstation 20 zugeordnet, von denen jeweils eine obere Druckrolle 22 bzw. 24 zu sehen ist. Die Druckrollen wirken bekanntlich mit den Preßstempeln zusammen, um das Material in den Matrizenbohrungen zu verpressen.A rotor 10 of a double rotary press is shown in FIGS. 1 and 2, which is reproduced only in intimations. The rotor can be driven in rotation about a vertical axis (in FIG. 1 perpendicular to the plane of the drawing) by means of a rotary drive. The rotor 10 includes upper and lower punches, which are guided in punch guides. Both are also not drawn. The rotor has a die plate 12, which has a number of die holes on a pitch circle 14. The Matrizenbohrungen are not shown, but only the compacts, which are rectangular in the present embodiment. The rotor 10 is associated with a first filling device 16, by means of which powder to be pressed is introduced into the die bores. The rotor rotates in the embodiment opposite to the clockwise direction. In the direction of rotation of the rotor 10 thereafter a Vorpreßstation 18 and a Hauptpreßstation 20 are assigned, of which in each case an upper pressure roller 22 and 24 can be seen. The pressure rollers are known to interact with the dies to press the material into the die bores.

Eine zweite Fülleinrichtung 26 liegt der ersten diametral gegenüber und ihr folgen in Drehrichtung eine zweite Vorpreßstation 28 und eine Hauptpreßstation 30, von welchen jeweils nur die obere Druckrolle 32 bzw. 34 zu erkennen ist.A second filling device 26 is the first diametrically opposite and follow it in the direction of rotation, a second Vorpreßstation 28 and a Hauptpreßstation 30, of which only the upper pressure roller 32 and 34 can be seen.

Radial außerhalb der Matrizenscheibe 12 ist eine Ringfläche 36 am Rotor 10 vorgesehen, die konzentrisch zur Drehachse verläuft und tiefer liegt als die Oberseite der Matrizenscheibe 12.Radially outside the die plate 12, an annular surface 36 is provided on the rotor 10 which is concentric with the axis of rotation and is lower than the top of the die plate 12th

Zwischen der zweiten Hauptpreßstation 30 und der ersten Füllvorrichtung 16 ist ein wenig oberhalb der Matrizenscheibe ein Umlenkblech 38 angeordnet. Es dient dazu, die von den Unterstempeln ausgestoßenen ersten Preßlinge 40 von der Oberseite der Matrizenplatte 12 zur Ringfläche 36 zu lenken. Dadurch bewegen sich die ersten Preßlinge 40 ungehindert durch die erste Füllvorrichtung 16 und die erste Vorpreßstation 18 und die erste Hauptpreßstation 20. Ein zweiter, kurz oberhalb der horizontalen Ringfläche 36 angeordneter Ablenkabschnitt 42 lenkt die ersten Preßlinge 40 von der Ringfläche 36 in einen ersten Auslaufkanal 44. In Drehrichtung kurz hinter dem zweiten Ablenkmittel ist ein dritter Ablenkabschnitt 46 in Form eines Abstreifers vorgesehen, der zweite Preßlinge 48 von der Oberseite der Matrizenscheibe 12 in einen zweiten Auslaufkanal 50 umlenkt, der parallel zum ersten Kanal 44 angeordnet ist.Between the second Hauptpreßstation 30 and the first filling device 16, a baffle 38 is disposed a little above the die plate. It serves to direct the first compacts 40 ejected from the lower punches from the upper side of the die plate 12 to the annular surface 36. As a result, the first compacts 40 move freely through the first filling device 16 and the first Vorpreßstation 18 and the first Hauptpreßstation 20. A second, located just above the horizontal annular surface 36 deflection section 42 directs the first compacts 40 from the annular surface 36 in a first outlet channel 44th In the direction of rotation shortly after the second deflecting means, a third deflecting section 46 in the form of a scraper is provided which deflects second compacts 48 from the upper side of the die plate 12 into a second outlet channel 50, which is arranged parallel to the first channel 44.

Wie zu erkennen, werden die ersten Preßlinge 40 in der ersten Preßstation 28, 30 erzeugt und hinter der Hauptpreßstation 30 ausgestoßen und dann auf die Ringfläche 36 gelenkt. Die zweiten Preßlinge 48 werden in der zweiten Preßstation 18, 20 erzeugt und die ausgestoßenen Preßlinge werden in üblicherweise vom Abstreifer 46 in den Auslaufkanal 50 gelenkt. Die Preßlinge 40 auf der Ringfläche 36 werden, wie beschrieben, in den Auslaufkanal 44 gelenkt. Durch die beschriebene Maßnahme ist es daher möglich, das Entfernen der Preßlinge 40, 48 am gleichen Ort am Umfang des Rotors 10 vorzunehmen.As can be seen, the first compacts 40 are produced in the first pressing station 28, 30 and ejected behind the Hauptpreßstation 30 and then directed to the annular surface 36. The second compacts 48 are produced in the second pressing station 18, 20 and the ejected compacts are usually directed by the scraper 46 in the outlet channel 50. The compacts 40 on the annular surface 36 are, as described, directed into the outlet channel 44. By the measure described, it is therefore possible to carry out the removal of the compacts 40, 48 at the same location on the circumference of the rotor 10.

Damit die Preßlinge nicht seitlich von der Ringfläche 36 abrutschen, hat diese einen erhabenen Rand 52.So that the compacts do not slip off the side of the annular surface 36, this has a raised edge 52nd

Es versteht sich, daß das beschriebene Prinzip nicht nur auf Doppel-Rundläuferpressen anwendbar ist, sondern auch auf Drei- oder Mehrfach-Rundläuferpressen.It is understood that the described principle is not only applicable to double rotary presses, but also to three or more rotary presses.
