Die Erfindung betrifft eine Presse insbesondere eine Rundläuferpresse, umfassend ein Pressengehäuse, in dem mehrere Betriebskomponenten der Presse angeordnet sind, weiter umfassend Leistungskomponenten, die die Betriebskomponenten zum Betrieb mit elektrischer Energie versorgen und umfassend Steuerungskomponenten, die mit den Betriebskomponenten Steuer- und/oder Messsignale und mit den Leistungskomponenten Steuersignale austauschen, gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a press, in particular a rotary press, comprising a press housing in which a plurality of operating components of the press are arranged, further comprising power components that supply the operating components for operation with electrical energy and comprising control components that control and / or measuring signals with the operating components and with the power components exchange control signals, according to the preamble of claim 1.

Eine Rundläuferpresse ist beispielsweise bekannt aus DE 10 2007 034 359 B3 . Die Steuerungs- und Leistungskomponenten zur Steuerung der Betriebskomponenten, beispielsweise eines Drehantriebs des Rotors der Presse, und zur Versorgung der Betriebskomponenten mit elektrischer Energie sind bei der bekannten Presse in einem Schaltschrank angeordnet. Der Schaltschrank ist in einem Pressengehäuse integriert. Es ist auch bekannt, derartige Schaltschränke außerhalb des Pressengehäuses anzuordnen. Der Schaltschrank ist dann über verschiedene Steuer- und Leistungsleitungen mit der Presse verbunden. Bekannte Pressen weisen konzeptionell bedingt eine fest vorgegebene Anordnung des Schaltschrankes auf. Der Betreiber einer Presse muss sich bei der Auswahl der Presse mit der jeweils konzeptbedingten Anordnung des Schaltschrankes abfinden. Befindet sich der Schaltschrank innerhalb des Pressengehäuses oder ist er an diesem befestigt, ist konzeptionell keine von dem Pressengehäuse getrennte Anordnung des Schaltschrankes möglich. Befindet sich der Schaltschrank bei der Presse dagegen konzeptionell getrennt von und außerhalb des Pressengehäuses, ist konzeptionell bedingt keine Anordnung innerhalb des oder an dem Pressengehäuse möglich. Darüber hinaus muss bei extern angeordneten Schaltschränken eine Vielzahl von Verbindungsleitungen für die Verbindung der Betriebskomponenten mit den Steuerungs- und Leistungskomponenten durch den Produktionsraum geführt werden, was oftmals unerwünscht ist.For example, a rotary press is known DE 10 2007 034 359 B3 , The control and power components for controlling the operating components, such as a rotary drive of the rotor of the press, and for supplying the operating components with electrical energy are arranged in the known press in a control cabinet. The control cabinet is integrated in a press housing. It is also known to arrange such cabinets outside of the press housing. The control cabinet is then connected to the press via various control and power cables. Known presses have conceptually a fixed predetermined arrangement of the cabinet. The operator of a press must accept the selection of the press with the concept-related arrangement of the control cabinet. If the control cabinet is located inside the press housing or is attached to it, conceptually no arrangement of the control cabinet separate from the press housing is possible. Conversely, if the control cabinet of the press is conceptually separate from and outside the press housing, no arrangement within or on the press housing is conceptually possible. In addition, in externally arranged cabinets, a plurality of connecting lines for the connection of the operating components with the control and power components must be passed through the production room, which is often undesirable.

Aus DE 20 2005 011 876 U1 ist eine Presse, insbesondere Rundläuferpresse bekannt geworden, bei der außerhalb des Pressengehäuses ein Schaltschrank mit einem Maschinenrechner angeordnet ist. Getrennt zum Schaltschrank ist ein Bedienpult vorgesehen, das einen Bedienrechner enthält. Sowohl Bedienpult als auch Schaltschrank sind über drahtlose Kommunikation mit Komponenten im Pressengehäuse verbunden. Außerdem ist zwischen dem Schaltschrank und dem Pressengehäuse ein Kabel vorgesehen. Der Schaltschrank enthält neben Leistungskomponenten auch Steuerungskomponenten, und Steuersignale werden über die drahtlose Kommunikation vom Schaltschrank zum Pressengehäuse und umgekehrt übertragen.Out DE 20 2005 011 876 U1 is a press, in particular rotary press has become known in the outside of the press housing, a cabinet is arranged with a machine computer. Separately to the control cabinet, a control panel is provided which contains a control computer. Both the control panel and the control cabinet are connected to components in the press housing via wireless communication. In addition, a cable is provided between the cabinet and the press housing. In addition to power components, the control cabinet also contains control components, and control signals are transmitted via wireless communication from the control cabinet to the press housing and vice versa.

Aus EP 1 602 474 A1 ist bekannt geworden, einen Schaltschrank für eine Tablettenpresse unmittelbar an dem Gehäuse der Tablettenpresse anzubringen. Der Schaltschrank enthält Leistungseinheiten sowie eine Steuerschaltung für Komponenten der Presse.Out EP 1 602 474 A1 It has become known to attach a cabinet for a tablet press directly to the housing of the tablet press. The control cabinet contains power units as well as a control circuit for components of the press.

Aus CN 201 653 291 U ist bekannt geworden, Steuerungskomponenten für eine Rundläuferpresse in einem Steuerungsschaltschrank anzuordnen. Die Kommunikation zwischen Leistungs- und Steuerungskomponenten mit der Presse findet über eine einzige Leitungsverbindung statt.Out CN 201 653 291 U It has become known to arrange control components for a rotary press in a control cabinet. The communication between power and control components with the press takes place over a single line connection.

Ausgehend von dem erläuterten Stand der Technik liegt der Erfindung die Aufgabe zugrunde, eine Presse der eingangs genannten Art bereitzustellen, bei der die Flexibilität hinsichtlich der Anordnung des Schaltschrankes erhöht und die Anzahl der durch den Produktionsraum zu führenden Leitungen reduziert ist.Based on the explained prior art, the present invention seeks to provide a press of the type mentioned, in which increases the flexibility in terms of the arrangement of the cabinet and the number of leading through the production room lines is reduced.

Die Erfindung löst diese Aufgabe durch den Gegenstand des kennzeichnenden Teils des Anspruchs 1.The invention solves this problem by the subject of the characterizing part of claim 1.

Vorteilhafte Ausgestaltungen finden sich in den abhängigen Ansprüchen, der Beschreibung und den Figuren.Advantageous embodiments can be found in the dependent claims, the description and the figures.

Für eine Presse der eingangs genannten Art löst die Erfindung die Aufgabe dadurch, dass die Leistungskomponenten getrennt von den Steuerungskomponenten in einem eigenständigen Leistungsgehäuse angeordnet sind, welches wahlweise von außen an oder in dem Pressengehäuse oder außerhalb des Pressengehäuses und getrennt von diesem angeordnet werden kann. Die Steuerungskomponenten sind in oder an dem Pressengehöuse in einem Steuerungsschaltschrank angeordnet.For a press of the type mentioned above, the invention solves the problem in that the power components are arranged separately from the control components in a separate power housing, which can be optionally arranged from the outside or in the press housing or outside of the press housing and separately. The control components are arranged in or on the press frame in a control cabinet.

Bei den Betriebskomponenten der Presse, die insbesondere eine Rundläuferpresse, beispielsweise eine Rundläufertablettenpresse, sein kann, kann es sich um Pressstempel, Füllstationen, Dosierstationen, Druckstationen, Auswerferstationen oder Messeinrichtungen, beispielsweise Kraftmesseinrichtungen, optische Messeinrichtungen, Temperaturmesseinrichtungen, etc., handeln. Sofern es sich bei der Presse um eine Rundläuferpresse handelt, kann es sich bei den Betriebskomponenten auch um einen Rotor der Rundläuferpresse handeln, der üblicherweise eine Matrizenscheibe und Ober- und Unterstempelführungen umfasst. Bei der Betriebskomponente kann es sich auch um einen Drehantrieb für den Rotor handeln.The operating components of the press, which may be in particular a rotary press, for example a rotary tablet press, can be press dies, filling stations, metering stations, printing stations, ejection stations or measuring devices, for example force measuring devices, optical measuring devices, temperature measuring devices, etc. If the press is a rotary press, the operating components may also be a rotor of the rotary press, which usually comprises a die plate and top and bottom punch guides. The operating component may also be a rotary drive for the rotor.

Die Leistungskomponenten sind insbesondere Komponenten aus dem Bereich der Leistungselektronik. Es handelt sich um Versorgungskomponenten. Sie versorgen die Betriebskomponenten, beispielsweise den Drehantrieb eines Rotors, mit elek trischer Energie für den Produktionsbetrieb. Beispiele für Leistungskomponenten sind Netzgeräte, Frequenzumrichter, Transformatoren etc.The power components are in particular components in the field of power electronics. These are supply components. They supply the operating components, such as the rotary drive of a rotor, with elek energy for the production plant. Examples of power components are power supplies, frequency converters, transformers, etc.

Die Steuerungskomponenten steuern die Betriebskomponenten im Produktionsbetrieb der Presse an. Bei den Steuerungskomponenten kann es sich insbesondere um die Maschinensteuerung der Presse oder eine Sicherheitssteuereinrichtung der Presse handeln. Auch kann es sich um einen Steuer- oder Messcomputer (PC) handeln. Die Steuerungskomponenten können von den Betriebskomponenten auch Messsignale oder ähnliches erhalten. Steuersignale umfassen in diesem Zusammenhang also auch Messsignale. Es kann somit eine bidirektionale Signalübertragung erfolgen. Auf Grundlage solcher Messsignale kann in an sich bekannter Weise eine Steuerung und/oder Regelung der Betriebskomponenten der Presse durch die Steuerungskomponenten erfolgen.The control components control the operating components in the production operation of the press. The control components can in particular be the machine control of the press or a safety control device of the press. It can also be a control or measuring computer (PC). The control components can also receive measurement signals or the like from the operating components. Control signals therefore also include measurement signals in this context. It can thus be a bidirectional signal transmission. On the basis of such measurement signals, control and / or regulation of the operating components of the press by the control components can be carried out in a manner known per se.

Hinsichtlich der zwischen den Steuerungskomponenten und den Betriebskomponenten ausgetauschten Signale, bei denen es sich wie erläutert um Mess- und Steuersignale handeln kann, sind lange Leitungswege unerwünscht. Zum einen leidet darunter die Signalqualität. Zum anderen müssen die Leitungen zum Übertragen der Mess- und Steuersignale im Gegensatz zu den Leitungen für die Leistungsversorgung häufig vieladrig sein. Es ist unerwünscht, wenn diese aufwendig gestalteten Leitungen außerhalb des Pressengehäuses durch den die Presse aufnehmenden Produktionsraum geführt werden. Außerdem stellt bei solchen Leitungen für Steuerungssignale jede Trennstelle, beispielsweise beim Eintritt in bzw. Austritt aus einem Gehäuse, ein Risiko für die Signalübertragung dar. Solche Trennstellen werden erfindungsgemäß weitestgehend vermieden, indem die Steuerungskomponenten nahe an den Betriebskomponenten angeordnet werden können.With regard to the signals exchanged between the control components and the operating components, which may be measuring and control signals as explained, long conduction paths are undesirable. On the one hand suffers the signal quality. On the other hand, the lines for transmitting the measurement and control signals, in contrast to the lines for the power supply often have to be multi-core. It is undesirable if these elaborately designed lines outside the press housing are guided by the production space receiving the press. In addition, in such lines for control signals each separation point, for example, when entering or leaving a housing, a risk for the signal transmission. Such separation points are inventively largely avoided by the control components can be placed close to the operating components.

Erfindungsgemäß ist erkannt worden, dass die Leistungskomponenten im Gegensatz zu den Steuerungskomponenten problemlos über längere Leitungswege mit den Betriebskomponenten verbunden werden können, ohne dass die Leistungsversorgung hierdurch leidet. Auf dieser Grundlage ist erfindungsgemäß eine räumliche Trennung der Steuerungskomponenten von den Leistungskomponenten vorgesehen. Durch die separate Anordnung der Leistungskomponenten in einem Leistungsgehäuse besteht für den Betreiber der Presse eine hohe Flexibilität hinsichtlich der Anordnung des Leistungsgehäuses. So kann der Betreiber der Presse die Anordnung dieses Leistungsgehäuses auch noch nach einer bereits erfolgten Inbetriebnahme der Presse in flexibler Weise wieder ändern, falls dies beispielsweise aufgrund geänderter räumlicher oder produktionstechnischer Bedingungen gewünscht sein sollte. Die Verbindungsleitungen des Leistungsgehäuses zur Verbindung der Leistungskomponenten mit den Betriebskomponenten zum einen und zur Verbindung der Leistungskomponenten mit den Steuerungskomponenten, insbesondere wenn diese im Pressengehäuse angeordnet sind, zum anderen und gegebenenfalls vorgesehene Verbindungsmittel zwischen dem Leistungsgehäuse und dem Pressengehäuse sind derart ausgeführt, dass ein flexibler und wahlweiser Wechsel zwischen der Anordnung des Leistungsgehäuses von außen an oder in dem Pressengehäuse einerseits und außerhalb des Pressengehäuses und getrennt von diesem andererseits möglich ist.According to the invention it has been recognized that the power components in contrast to the control components easily over longer cable paths with the Operating components can be connected without the power supply suffers. On this basis, a spatial separation of the control components from the power components is provided according to the invention. The separate arrangement of the power components in a power housing for the operator of the press has a high flexibility in terms of the arrangement of the power housing. Thus, the operator of the press can change the arrangement of this power housing even after a successful commissioning of the press in a flexible manner, if this should be desired, for example, due to changed spatial or production-technical conditions. The connection lines of the power housing for connecting the power components with the operating components on the one hand and for connecting the power components with the control components, especially if they are arranged in the press housing, and on the other and optionally provided connecting means between the power housing and the press housing are designed such that a flexible and optional change between the arrangement of the power housing from the outside or in the press housing on the one hand and outside of the press housing and on the other hand is possible separately.

Ein Käufer einer bestimmten Presse kann daher frei festlegen, ob das Leistungsgehäuse mit den Leistungskomponenten intern angeordnet sein soll, also innerhalb des Pressengehäuses oder an letzterem, oder ob das Leistungsgehäuse extern angeordnet werden soll, also außerhalb des Pressengehäuses und separat von letzterem. Es ist insbesondere auch eine nachträgliche Änderung zwischen einer internen und einer externen Anordnung des Leistungsgehäuses möglich. Da die Steuerungskomponenten von den Leistungskomponenten räumlich getrennt sind, bleiben die Signalwege zwischen den Steuerungskomponenten und den Betriebskomponenten unabhängig von der Anordnung und Konfiguration des Leistungsgehäuses immer gleich. Dadurch wird eine gleichbleibend hohe Signalqualität der Steuerungssignale, insbesondere der Messsignale, erreicht, da jederzeit definierte Leitungslängen für sämtliche Signalleitungen der Steuerungskomponenten zur Verfügung stehen. Außerdem werden die insbesondere hinsichtlich der Steuerungssignale problematischen Trennstellen vermieden. Die Betriebssicherheit wird erhöht und eine Wartung und Auffindbarkeit von Fehlern vereinfacht. Die Steuerungskomponenten sind in einem Steuerungsschaltschrank in oder an dem Pressengehäuse angeordnet. Es müssen dann nur noch jene Steuerungsleitungen aus dem Pressengehäuse heraus geführt werden, die Steuersignale zu den Leistungskomponenten übertragen, wenn sich letztere in einem außerhalb des Pressengehäuses und getrennt von diesem angeordneten Leistungsgehäuse befinden.A purchaser of a particular press can therefore freely determine whether the power housing is to be internally located with the power components, ie within the press housing or the latter, or whether the power housing is to be located externally, ie outside the press housing and separately from the latter. In particular, a subsequent change between an internal and an external arrangement of the power housing is possible. Because the control components are physically separate from the power components, the signal paths between the control components and the operating components always remain the same, regardless of the power box arrangement and configuration. This will be a consistently high Signal quality of the control signals, in particular the measurement signals, achieved because any time defined line lengths for all signal lines of the control components are available. In addition, the problematic separation points in particular with regard to the control signals are avoided. Operational reliability is increased and maintenance and fault finding easier. The control components are arranged in a control cabinet in or on the press housing. Then, only those control lines need to be led out of the press housing which transmit control signals to the power components when the latter are located in a power housing located outside the press housing and separate therefrom.

Nach einer weiteren Ausgestaltung kann das Leistungsgehäuse einen Leistungsschaltschrank umfassen, in dem die Leistungskomponenten angeordnet sind. Beispielsweise kann der Leistungsschaltschrank in dem Leistungsgehäuse angeordnet sein. Eine solche Ausgestaltung eignet sich besonders gut für eine externe Anordnung der Leistungskomponenten an einem von dem Pressengehäuse entfernten Ort. Dazu kann der Leistungsschaltschrank über eine in das Pressengehäuse geführte Leitungsverbindung mit den Betriebskomponenten und mit den im Pressengehäuse angeordneten Steuerungskomponenten verbindbar sein bzw. verbunden sein. Es kann auch eine Kühleinrichtung zur Kühlung der Leistungskomponenten vorgesehen sein. Diese kann beispielsweise in einem Zwischenraum zwischen dem Leistungsgehäuse und einem darin angeordneten Schaltschrank vorgesehen sein. Selbstverständlich ist es auch möglich, dass das erfindungsgemäße Leistungsgehäuse selbst einen Leistungsschaltschrank bildet.According to a further embodiment, the power housing may comprise a power switching cabinet, in which the power components are arranged. For example, the power switch cabinet may be arranged in the power housing. Such a configuration is particularly well suited for an external arrangement of the power components at a location remote from the press housing. For this purpose, the power switching cabinet can be connectable or connected via a line connection guided into the press housing with the operating components and with the control components arranged in the press housing. It can also be provided a cooling device for cooling the power components. This can be provided for example in a space between the power housing and a control cabinet arranged therein. Of course, it is also possible that the power housing according to the invention itself forms a power switching cabinet.

Nach einer weiteren besonders praxisgemäßen Ausgestaltung kann eine Verbindung, beispielsweise eine Flanschverbindung, vorgesehen sein zur Befestigung des Leistungsgehäuses von außen an oder in dem Pressengehäuse.According to another particularly practical embodiment, a connection, for example a flange connection, be provided for fastening the power housing from the outside or in the press housing.

Wie erläutert, kann es sich bei der Presse um eine Rundläuferpresse handeln. Die Rundläuferpresse kann einen im Regelfall um eine vertikale Achse drehbaren Rotor mit einer oberen und einer unteren Stempelführung und mit einer Matrizenscheibe zwischen den Stempelführungen umfassen. Weiterhin kann sie eine Vielzahl von oberen und unteren Pressstempeln umfassen, wobei die Presstempel mit Matrizenbohrungen der Matrizenscheibe zusammenwirken. Ferner kann die Rundläuferpresse mindestens eine Füllstation und mindestens eine Dosierstation umfassen, in denen zu verpressendes Material in die Matrizenbohrungen gefüllt und dosiert wird. Schließlich kann die Rundläuferpresse mindestens eine Druckstation umfassen, in der das in die Matrizenbohrungen gefüllte und dosierte Material durch die oberen und unteren Pressstempel zu Presslingen verpresst wird.As explained, the press may be a rotary press.

Zur Steuerung dieser Betriebskomponenten sind Steuerungskomponenten vorgesehen, insbesondere in Form einer Maschinensteuerung. In dem gezeigten Beispiel sind die Steuerungskomponenten in einem innerhalb des Pressengehäuses 12 angeordneten Steuerungsschaltschrank 14 untergebracht. Die Steuerungskomponenten erhalten auch Messsignale von den Messeinrichtungen. Unter anderem auf dieser Grundlage steuern die Steuerungskomponenten die Betriebskomponenten und auch nachfolgend noch genannte Leistungskomponenten der Presse im Betrieb an. Auf Grundlage der Messsignale erfolgt in dem dargestellten Beispiel auch eine Regelung der Betriebskomponenten durch die Steuerungskomponenten.To control these operating components control components are provided, in particular in the form of a machine control. In the example shown, the control components are accommodated in a control cabinet 14 arranged inside the press housing 12. The control components also receive measurement signals from the measuring devices. Among other things, on this basis, the control components control the operating components and also the below-mentioned performance components of the press during operation. On the basis of the measurement signals, a control of the operating components by the control components takes place in the illustrated example.

Räumlich getrennt von den in dem Steuerungsschaltschrank 14 angeordneten Steuerungskomponenten sind in einem Leistungsgehäuse 16 Leistungskomponenten zur elektrischen Versorgung der Betriebskomponenten der Presse angeordnet. In dem gezeigten Beispiel befinden sich die Leistungskomponenten in einem Leistungsschaltschrank 18, der innerhalb des Leistungsgehäuses 16 angeordnet ist. In einem Zwischenraum zwischen dem Leistungsgehäuse 16 und dem Leistungsschaltschrank 18 kann eine Kühleinrichtung zur Kühlung des Leistungsschaltschranks 18 und insbesondere der darin befindlichen Leistungskomponenten vorgesehen sein. In dem in Fig. 1 gezeigten Beispiel ist das Leistungsgehäuse 16 mit dem darin befindlichen Leistungsschaltschrank 18 und den wiederum darin befindlichen Leistungskomponenten von außen an einer Außenwand des Pressengehäuses 12 befestigt. Die Befestigung erfolgt in dem gezeigten Beispiel durch eine nicht näher dargestellte Flanschverbindung.Spatially separated from the control components arranged in the control cabinet 14 16 power components for the electrical supply of the operating components of the press are arranged in a power housing. In the example shown, the power components are located in a power switching cabinet 18 which is disposed within the power enclosure 16. In a space between the power housing 16 and the power cabinet 18 may be provided a cooling device for cooling the power cabinet 18 and in particular the power components located therein. In the in Fig. 1 In the example shown, the power housing 16, with the power switching cabinet 18 located therein and the power components in turn, is fastened from the outside to an outer wall of the press housing 12. The attachment is made in the example shown by a flange connection, not shown.

In Fig. 2 ist die Presse aus Fig. 1 in einer zweiten Aggregationsvariante dargestellt. Die Ausbildung des Pressengehäuses 12 einschließlich der darin angeordneten Betriebskomponenten und des Steuerungsschaltschranks 14 sowie seiner Anordnung ist identisch zu der in Fig. 1 gezeigten Aggregationsvariante. Im Unterschied zu Fig. 1 ist bei der zweiten Aggregationsvariante nach Fig. 2 allerdings das Leistungsgehäuse 16 mit dem Leistungsschaltschrank 18 außerhalb des Pressengehäuses 12 und räumlich getrennt von diesem angeordnet. Zu erkennen ist in Fig. 2, dass das Leistungsgehäuse 16 über Standbeine 20 getrennt von dem Pressengehäuse 12 aufgestellt ist. Es ist eine Leitungsverbindung 22, im Regelfall eine Vielzahl von Verbindungskabeln umfassend, vorgesehen, die einerseits mit dem Leistungsgehäuse 16 bzw. dem Leistungsschaltschrank 18 und den darin angeordneten Leistungskomponenten verbunden ist. Andererseits ist die Leitungsverbindung 22 in das Pressengehäuse 12 geführt und in nicht näher dargestellter Weise sind Verbindungskabel der Leitungsverbindung 22 mit den Betriebskomponenten und andere Verbindungskabel mit den Steuerungskomponenten der Presse verbunden. Die Ausgestaltung des Leistungsgehäuses 16 und des Leistungsschaltschranks 18, insbesondere ihre Basis und ihre Befestigungsmittel, einschließlich der Leitungsverbindung 22 ist dabei derart, dass in flexibler Weise und auch noch nachträglich nach einer Inbetriebnahme der Presse ein Wechsel zwischen den in Fig. 1 und Fig. 2 gezeigten Anordnungen des Leistungsgehäuses 16 mit den Leistungskomponenten möglich ist. Die Steuerungskomponenten bleiben aufgrund der von den Leistungskomponenten separaten Anordnung dabei jederzeit in ihrer festen Position innerhalb des Steuerungsschaltschranks 14. Das gleiche gilt für sensible Signalverarbeitungsleitungen zwischen den Steuerungskomponenten und den Betriebskomponenten, die Steuer- und/oder Messsignale führen.In Fig. 2 the press is out Fig. 1 presented in a second aggregation variant. The formation of the press housing 12 including the operating components and the control cabinet 14 arranged therein as well as its arrangement is identical to that in FIG Fig. 1 shown aggregation variant.
