Die Erfindung betrifft außerdem eine Rundläuferpresse mit einem um eine vertikale Achse drehbaren Rotor, wobei der Rotor eine obere und eine untere Stempelführung für obere und untere Pressstempel und eine Matrizenscheibe zwischen den Stempelführungen aufweist, wobei die Pressstempel mit Aufnahmen der Matrizenscheibe zusammenwirken, ferner mit mindestens einer Füll- und Dosierstation sowie mit mindestens einer oberen Druckeinrichtung und mindestens einer unteren Druckeinrichtung, die im Betrieb mit den oberen Pressstempeln und mit den unteren Pressstempeln zusammenwirken. The invention also relates to a rotary press having a rotor rotatable about a vertical axis, the rotor having upper and lower punch guides for upper and lower rams and a die plate between the ram guides, the rams cooperating with receptacles of the die plate, and at least one Filling and dosing station and with at least one upper pressure device and at least one lower pressure device, which cooperate in operation with the upper press dies and with the lower press dies.
Eine derartige Rundläuferpresse ist beispielsweise bekannt aus DE 10 2007 057 791 B4. Sie umfasst obere und untere Druckeinrichtungen, wobei jeweils eine obere Druckeinrichtung und eine untere Druckeinrichtung gemeinsam eine Druckstation bilden. Es sind mehrere Druckstationen vorgesehen, beispielsweise eine Vordruckstation und eine Hauptdruckstation. Bei der bekannten Rundläuferpresse umfasst jede Druckeinrichtung eine Druckrolle, die mit den Stempelköpfen zusammenwirkt. Es ist bekannt, den Druckeinrichtungen Kraftmesseinrichtungen zuzuordnen. Auf Grundlage einer im Zuge des Pressvorgangs durchgeführten Kraftmessung können Rückschlüsse auf die Qualität der hergestellten Tabletten getroffen werden. Die Kjaftmesseinrichtungen sind dabei innerhalb der Such a rotary press is known for example from DE 10 2007 057 791 B4. It comprises upper and lower printing devices, wherein an upper printing device and a lower printing device together form a printing station. Several printing stations are provided, for example a pre-printing station and a main printing station. In the known rotary press each printing device comprises a pressure roller which cooperates with the punch heads. It is known to associate the pressure devices with force measuring devices.

BESTÄTIGUNGSKOPIE Druckeinrichtungen angeordnet und in der Betriebsstellung der Presse von außen nicht zugänglich. CONFIRMATION COPY Pressure devices arranged and not accessible from the outside in the operating position of the press.
Es kann erforderlich sein, die Kraftmesseinrichtungen beispielsweise für eine Wartung oder Reparatur zu entnehmen. Auch kann es erforderlich sein, eine vorhandene Kraftmesseinrichtung gegen eine andere Kraftmesseinrichtung auszutauschen, beispielsweise wenn sich der von der Kraftmesseinrichtung zu erfassende Presskraftbereich stark ändert. Dies ist zum Beispiel der Fall bei einem Wechsel zwischen einem Betriebszustand, bei dem Einschichttabletten verpresst werden zu einem Betriebszustand, bei dem Mehrschichttabletten verpresst werden. Ebenfalls erhebliche Presskraftunterschiede bestehen zwischen der Vordruckstation und der Hauptdruckstation. Soll beispielsweise eine bislang als Hauptdruckstation genutzte Druckstation in einem anderen Betriebsmodus als Vordruckstation genutzt werden, oder umgekehrt, kann ebenfalls ein Austausch der Kraftmesseinrichtung erforderlich werden. Bei Druckeinrichtungen bzw. Rundläuferpressen nach dem Stand der Technik ist hierzu eine aufwendige Demontage zumindest der Druckrolle der jeweiligen Druckeinrichtung oder sogar eine umfassende Demontage der gesamten Druckeinrichtung erforderlich. Aufgrund des hohen Gewichts der beteiligten Bauteile, insbesondere der Druckrollen, ist hiermit ein großer Kraftaufwand für die jeweilige Bedienperson verbunden. Außerdem ist dieses Vorgehen auch in zeitlicher Hinsicht von erheblichem Aufwand. It may be necessary to remove the force measuring devices, for example for maintenance or repair. It may also be necessary to replace an existing force measuring device with another force measuring device, for example if the pressing force range to be detected by the force measuring device changes greatly. This is the case, for example, when switching between an operating state in which monolayer tablets are compressed to an operating state in which multilayer tablets are compressed. Also considerable differences in press force exist between the pre-press station and the main printing station. If, for example, a print station previously used as a main printing station is to be used in a different operating mode as a pre-printing station, or vice versa, an exchange of the force measuring device may also be required. In printing devices or rotary presses according to the prior art, a costly disassembly of at least the pressure roller of the respective printing device or even a comprehensive disassembly of the entire printing device is required for this purpose. Due to the high weight of the components involved, in particular the pressure rollers, this is a great effort for each operator connected. Moreover, this procedure is also in terms of time of considerable effort.
Ausgehend von dem erläuterten Stand der Technik liegt der Erfindung die Aufgabe zugrunde, eine Wartung, Reparatur oder einen Austausch einer Kraftmesseinrichtung einer Druckeinrichtung in einfacher und kostensparender Weise zu ermöglichen. Die Erfindung löst diese Aufgabe durch die Ansprüche 1 und 7. Vorteilhafte Ausgestaltungen finden sich in den abhängigen Ansprüchen, der Beschreibung und den Figuren. Based on the explained prior art, the invention has the object to enable a maintenance, repair or replacement of a force measuring device of a printing device in a simple and cost-saving manner. The invention achieves this object by the claims 1 and 7. Advantageous embodiments can be found in the dependent claims, the description and the figures.
Die Erfindung löst die Aufgabe zum einen durch eine Druckeinrichtung für eine Presse, insbesondere für eine Rundläuferpresse, wobei die Druckeinrichtung dazu ausgebildet ist, im Betrieb der Presse mit mindestens einem Pressstempel der Presse zusammenzuwirken, so dass der mindestens eine Pressstempel in einer Aufnahme der Presse befindliches Material verpresst, wobei die Druckeinrichtung eine Kraftmesseinrichtung zur Messung der von dem mindestens einen Pressstempel auf die Druckeinrichtung ausgeübten Kraft umfasst, wobei zumindest ein Abschnitt der Druckeinrichtung zwischen einer geschlossenen Betriebsposition und einer geöffneten Wartungsposition bewegbar ist, und wobei die Kraftmesseinrichtung in der geöffneten Wartungsposition von außen zumindest teilweise zugänglich ist. The invention solves the problem on the one hand by a pressure device for a press, in particular for a rotary press, wherein the pressure device is adapted to cooperate during operation of the press with at least one ram of the press, so that the at least one ram located in a receptacle of the press The material presses, wherein the pressure device comprises a force measuring device for measuring the force exerted by the at least one press die on the printing device, wherein at least a portion of the printing device between a closed operating position and an open maintenance position is movable, and wherein the force measuring device in the open maintenance position from the outside at least partially accessible.
Bei der Presse kann es sich um eine Tablettenpresse, insbesondere eine Rundläufertablettenpresse handeln, wie sie an sich bekannt ist. Die erfindungsgemäße Druckeinrichtung kann insbesondere Teil einer Druckstation der Presse sein. Hierzu können mindestens eine obere Druckeinrichtung und mindestens eine untere Druckeinrichtung vorgesehen sein, die gemeinsam eine Vordruck- und/oder Hauptdruckstation der Presse bilden. Die Druckeinrichtung besitzt mindestens ein Druckelement, beispielsweise eine Druckrolle, die im Betrieb der Presse mit den Pressstempeln in Kontakt tritt und diese in Aufnahmen der Presse für das zu verpressende Material, beispielsweise Matrizenbohrungen, drückt. Das Material kann pulverförmig sein. Es wird in an sich bekannter Weise von den Pressstempeln zu einem Pressling, beispielsweise einer Tablette, verpresst. Die erfindungsgemäße Druckeinrichtung besitzt in ebenfalls an sich bekannter Weise eine Kraftmesseinrichtung. Mit ihr wird die im Betrieb zwischen der Druckeinrichtung, insbesondere einem Druckelement, wie einer Druckrolle, und dem bzw. den Press- stempeln wirkende Kraft gemessen. Daraus können Rückschlüsse auf die Qualität der hergestellten Presslinge getroffen werden. The press may be a tablet press, in particular a rotary tablet press, as known per se. The printing device according to the invention may in particular be part of a printing station of the press. For this purpose, at least one upper printing device and at least one lower printing device can be provided, which together form a pre-printing and / or main printing station of the press. The printing device has at least one pressure element, for example a pressure roller, which comes into contact with the press dies during operation of the press and presses these in recordings of the press for the material to be pressed, for example die bores. The material can be powdery. It is pressed in a conventional manner from the press dies to a compact, for example a tablet. The printing device according to the invention also has a force measuring device in a manner known per se. With her is the in operation between the printing device, in particular a pressure element, such as a pressure roller, and the or the press stamping acting force measured. From this it is possible to draw conclusions about the quality of the produced compacts.
Erfindungsgemäß besitzt die Druckeinrichtung einen Abschnitt, der aus einer geschlossenen Betriebsposition für den Betrieb der Presse in eine geöffnete Wartungsposition für eine Wartung oder dergleichen der Kraftmesseinrichtung bewegbar ist. In der geöffneten Wartungsposition ist die innerhalb der Druckeinrichtung angeordnete Kraftmesseinrichtung für eine Bedienperson zumindest teilweise, insbesondere vollständig, zugänglich. Es kann somit eine teilweise oder vollständige Entnahme der Kraftmesseinrichtung für eine Wartung, eine Reparatur oder einen Austausch gegen eine andere Kraftmesseinrichtung erfolgen. Eine Demontage der Druckeinrichtung, beispielsweise eines Druckelements, wie einer Druckrolle, ist nicht erforderlich. Vielmehr kann durch die Trennung der Druckeinrichtung im Bereich der Kraftmesseinrichtung diese in einfacher Weise zugänglich gemacht werden. Hierdurch werden eine Wartung, Reparatur oder Austausch der Kraftmesseinrichtung im Vergleich zum Stand der Technik sowohl in zeitlicher Hinsicht als auch hinsichtlich der von einer Bedienperson aufzubringenden Kraft erheblich vereinfacht. According to the invention, the printing device has a portion which is movable from a closed operating position for the operation of the press in an open maintenance position for maintenance or the like of the force measuring device. In the open maintenance position, the force measuring device arranged within the pressure device is at least partially accessible to an operator, in particular completely. It can thus be a partial or complete removal of the force measuring device for maintenance, repair or replacement with another force measuring device. Disassembly of the printing device, such as a printing element, such as a pressure roller, is not required. Rather, it can be made accessible in a simple manner by the separation of the printing device in the field of force measuring device. As a result, a maintenance, repair or replacement of the force measuring device compared to the prior art, both in terms of time and in terms of applied by an operator force is greatly simplified.
Es kann vorgesehen sein, dass der bewegbare Abschnitt bei seiner Bewegung zwischen der geöffneten und der geschlossenen Betriebsposition zu jeder Zeit mit dem fest angeordneten Abschnitt der Druckeinrichtung verbunden bleibt. Beispielsweise wenn der bewegbare Abschnitt kein Druckelement umfasst, insbesondere wenn der bewegbare Abschnitt keine Druckrolle umfasst, kann aber auch vorgesehen sein, dass der bewegbare Abschnitt in seiner geöffneten Wartungsposition von dem fest angeordneten Abschnitt losgelöst ist. Die Kraftmesseinrichtung kann beispielsweise eine sogenannte Kraftmessdose bzw. ein sogenanntes Druckstück und einen Kraftsensor umfassen, wobei die Kraftmessdose bzw. das Druckstück im Betrieb den auftretenden Kräften bzw. Drücken ausgesetzt ist und diese auf den Kraftsensor übertragen. Es kann bei einer Wartung, Reparatur oder einem Austausch ausreichend sein, wenn nur die Kraftmessdose bzw. das Druckstück entnommen wird. Ebenso kann es ausreichend sein, nur den Kraftsensor zu entnehmen. Es kann daher vorgesehen sein, dass nur der jeweils zu entnehmende Teil der Kraftmesseinrichtung in der geöffneten Wartungsposition von außen zugänglich ist. Selbstverständlich ist es auch denkbar, dass die gesamte Kraftmesseinrichtung entnommen wird. In diesem Fall ist in der geöffneten Wartungsposition des bewegbaren Abschnitts der Druckeinrichtung die gesamte Kraftmesseinrichtung von außen zugänglich. It can be provided that the movable portion remains connected during its movement between the open and the closed operating position at any time with the fixed portion of the printing device. For example, if the movable section does not comprise a pressure element, in particular if the movable section does not comprise a pressure roller, it may also be provided that the movable section is released from the fixed section in its open maintenance position. The force measuring device may include, for example, a so-called load cell or a so-called pressure piece and a force sensor, wherein the load cell or the pressure piece exposed in operation to the forces or pressures occurring is and these transferred to the force sensor. It may be sufficient for a maintenance, repair or replacement, if only the load cell or the pressure piece is removed. It may also be sufficient to remove only the force sensor. It can therefore be provided that only the respectively to be removed part of the force measuring device in the open maintenance position is accessible from the outside. Of course, it is also conceivable that the entire force measuring device is removed. In this case, in the open maintenance position of the movable portion of the printing device, the entire force measuring device is accessible from the outside.
Nach einer Ausgestaltung kann vorgesehen sein, dass die Kraftmesseinrichtung in der geschlossenen Betriebsposition des bewegbaren Abschnitts von außen im Wesentlichen nicht zugänglich ist. Weiterhin kann vorgesehen sein, dass die Kraftmesseinrichtung in einer Aufnahme der Druckeinrichtung angeordnet ist. Mit diesen Ausgestaltungen wird die Kraftmesseinrichtung im Betrieb der Presse optimal geschützt. According to one embodiment, provision may be made for the force-measuring device to be substantially inaccessible from the outside in the closed operating position of the movable section. Furthermore, it can be provided that the force measuring device is arranged in a receptacle of the printing device. With these embodiments, the force measuring device is optimally protected during operation of the press.
Gemäß einer besonders praxisgemäßen Ausgestaltung kann der bewegbare Abschnitt der Druckeinrichtung zwischen der geschlossenen Betriebsposition und der geöffneten Wartungsposition verschwenkbar sein, insbesondere mittels eines Schwenklagers. Beispielsweise kann der bewegbare Abschnitt um eine vertikale oder um eine gegenüber einer Drehachse eines Rotors der Presse geneigte Schwenkachse verschwenkbar sein. Die Druckeinrichtung kann beispielsweise eine obere und eine untere Hälfte bzw. Gehäusehälfte, aufweisen, wobei die Kraftmesseinrichtung zwischen den beiden Hälften aufgenommen wird. Es kann dann die obere oder untere Hälfte der Druckeinrichtung aus der mit der unteren bzw. oberen Hälfte verbundenen geschlossenen Betriebsposition von der unteren bzw. oberen Hälfte der Druckeinrichtung weg in die geöffnete Wartungsposition geschwenkt werden. Der Begriff Verschwenken umfasst dabei auch ein Verdrehen des bewegbaren Abschnitts der Druckeinrichtung gegenüber dem übrigen, fest angeordneten Abschnitt der Druckeinrichtung um eine gemeinsame Zentralachse oder eine innen liegende Drehachse. Alternativ ist es auch denkbar, dass der bewegbare Abschnitt der Druckeinrichtung zwischen der geschlossenen Betriebsposition und der geöffneten Wartungsposition translatorisch verschiebbar ist. According to a particularly practical embodiment, the movable portion of the printing device between the closed operating position and the open maintenance position be pivotable, in particular by means of a pivot bearing. For example, the movable section may be pivotable about a pivot axis that is vertical or inclined about an axis of rotation of a rotor of the press. The pressure device can have, for example, an upper and a lower half or housing half, wherein the force measuring device is received between the two halves. Then, the upper or lower half of the printing device can be pivoted from the closed or upper half associated closed operating position from the lower and upper half of the printing device away in the open maintenance position. The term pivoting also includes a twisting the movable portion of the printing device relative to the remaining, fixed portion of the printing device about a common central axis or an internal axis of rotation. Alternatively, it is also conceivable that the movable portion of the printing device between the closed operating position and the open maintenance position is translationally displaceable.
Nach einer weiteren Ausgestaltung kann die Druckeinrichtung eine Druckrolle umfassen, die im Betrieb der Presse mit dem mindestens einen Pressstempel zusammenwirkt, wobei die Druckrolle an dem bewegbaren Abschnitt der Druckeinrichtung gelagert ist. Das Druckelement der Druckeinrichtung, beispielsweise eine Druckrolle, kann beispielsweise an einer schwenkbaren oberen oder unteren Hälfte angeordnet sein. Gerade bei den üblicherweise sehr schweren Druckrollen bietet die Erfindung somit große Vorteile, da diese für einen Zugang zu der Kraftmesseinrichtung nicht demontiert werden müssen. Außerdem ist der Zugang zu der Kraftmesseinrichtung bei dieser Ausgestaltung besonders einfach möglich. Die Kraftmesseinrichtung kann beispielsweise in einem vertikal verlaufenden Druckrollenbolzen angeordnet sein, an dessen Außenseite die Druckrolle befestigt ist. Natürlich ist es auch möglich, dass die Druckrolle an dem nicht bewegbaren Abschnitt der Druckeinrichtung gelagert ist.
