Description

Die Erfindung betrifft ein Druckmaschinenschmiersystem nach dem Oberbegriff von Anspruch 1 und ein Schmierstoffbereitstellungsverfahren nach dem Oberbegriff von Anspruch 21.The invention relates to a printing machine lubrication system according to the preamble of claim 1 and a lubricant supply method according to the preamble of claim 21.

Das Druckmaschinenschmiersystem dient als solches der Versorgung und der Rückführung von Schmieröl und ggf. Fett zu verschiedensten Schmierstellen innerhalb einer Druckmaschine. Ein zugehöriges Schmierstoffbereitstellungsverfahren dient der Sicherstellung einer hinreichenden Systemschmierung.As such, the printing machine lubrication system serves to supply and return lubricating oil and possibly grease to various lubrication points within a printing press. An associated lubricant supply method serves to ensure adequate system lubrication.

Bei den genannten Schmierstellen eines Druckmaschinenschmiersystems handelt es sich insbesondere um Gleit- und Wälzlagerstellen, um Zahnrad-, und Kettentriebe, sowie Gelenk-, Führungs- und Steuerkurveneinrichtungen. Diese Schmierstellen lassen sich zum Teil nur bedingt hermetisch abschließen, so dass im Rahmen des Betriebs der Druckmaschine Teile des Schmieröls entweichen, oder durch zudringende Medien, insbesondere Stäube, Farben und wässrige Medien verunreinigt werden können. Um die Schmierstoffversorgung an sich, sowie um eine ausreichende Qualität des Schmieröls sicherzustellen, wird dieses üblicherweise in der Druckmaschine und druckmaschinenbezogene Ölkreisläufe ggf. mit Ölwanne, und / oder in Verbindung mit einem separaten Sammelbehältnis, in einem relativ großen Vorratsvolumen bereitgehalten und im Rahmen des Betriebs der Druckmaschine gefiltert und in hinreichend kurzen Intervallen gewechselt.The aforementioned lubrication points of a printing machine lubrication system are, in particular, sliding and rolling bearing points, toothed wheel and chain drives, as well as joint, guide and control cam devices. Some of these lubrication points can only be hermetically sealed to a certain extent so that parts of the lubricating oil can escape during the operation of the printing press or can be contaminated by media to be penetrated, in particular dusts, paints and aqueous media. To ensure the supply of lubricant in itself, as well as to ensure a sufficient quality of the lubricating oil, this is usually held in the printing press and press related oil circuits possibly with oil pan, and / or in conjunction with a separate collection container, in a relatively large reservoir volume and within the operation the printing machine filtered and changed in sufficiently short intervals.

Aus DE 38 43 498 ist ein Zentralschmiersystem für Rotationsdruckmaschinen bekannt bei welchem das Schmieröl in einem zentralen Sammelbehälter zusammengeführt wird. Das aufgefangene Schmieröl wird derart aufgefangen, dass sich etwaig darin enthaltenes Wasser absetzen kann. Bei Auftreten von Wasser in dem Schmieröl wird ein Warnsignal erzeugt und die Maschine angehalten.Out DE 38 43 498 is a centralized lubrication system for rotary printing presses in which the lubricating oil is brought together in a central collecting container. The collected lubricating oil is collected so that any water contained therein can settle. When water appears in the lubricating oil, a warning signal is generated and the machine is stopped.

Aus der US 5;471,927 ist eine temperaturgesteuerte Druckmaschine bekannt. Die Druckmaschine enthält ein Kühlsystem für das Schmieröl. In dem Kühlsystem sind Anordnungen von Wärmetauschern zur Wärmeabführung aus dem Schmieröl vorgesehen. Die Aufheizung des Schmieröles wird in Verbindung mit dem Maschinenbetrieb ständig gemessen und davon abhängig gesteuert.From US 5,471,927 a temperature controlled printing machine is known. The printing press contains a cooling system for the lubricating oil. In the cooling system, arrangements of heat exchangers for removing heat from the lubricating oil are provided. The heating of the lubricating oil is constantly measured in connection with the machine operation and controlled by it.

Aus der US 6,260,664 B1 ist eine Anpassung eines Schmiersystems für eine Druckmaschine bekannt. Das Schmiersystem weist eine Vielzahl von Ventilen auf, die der gesteuerten Verteilung des Schmiermittels in der Druckmaschine dienen. Die Ventile sind als Magnetventile ausgeführt.From the US 6,260,664 B1 an adaptation of a lubrication system for a printing machine is known. The lubrication system includes a plurality of valves for controlling the distribution of the lubricant in the printing press. The valves are designed as solenoid valves.

Der Erfindung liegt die Aufgabe zugrunde, Lösungen zu schaffen durch welche ein sicherer und verschleißarmer Betrieb einer Rotationsdruckmaschine in einer unter betriebswirtschaftlichen und ökologischen Gesichtspunkten vorteilhaften Weise sichergestellt werden kann.The invention has for its object to provide solutions by which a safe and low-wear operation of a rotary printing machine can be ensured in an advantageous manner from a business and ecological point of view.

Diese Aufgabe wird erfindungsgemäß gelöst mit den Merkmalen einer Vorrichtung nach Anspruch 1 und den Merkmalen eines Verfahrens nach Anspruch 21.This object is achieved with the features of a device according to claim 1 and the features of a method according to claim 21.

Die Erfindung stellt sich also in einem Druckmaschinenschmiersystem dar, das der Versorgung und der Rückführung eines viskosen Schmierstoffes, insbesondere von Schmieröl und ggf. Fett von, bzw. zu mehreren Schmierstellen innerhalb einer Druckmaschine dient, mit einem Zubringungsabschnitt, zur Zubringung des Schmierstoffes zu den Schmierstellen, einem Rückführungsabschnitt zur Rückführung des Schmierstoffes und einem Fördersystem, zur Förderung des Schmierstoffes aus dem Rückführungsabschnitt in den Zubringungsabschnitt, wobei eine Sensoreinrichtung vorgesehen ist, zur Generierung hinsichtlich des Ölzustandes indikativer elektrischer Signale und eine elektronische Rechnereinrichtung vorgesehen ist, die derart ausgebildet ist, dass diese jene hinsichtlich des Ölzustandes indikativen Signale mit weiteren Maschinenbetriebsdaten verknüpft auswertet, wobei auf Grundlage dieser Auswertung ein Auswertungsergebnis generiert wird, das Aufschluss über das momentane Schmierleistungsvermögen oder den Verschleißzustand des Schmierstoffes gibt.Thus, the invention is in a printing machine lubrication system, which serves the supply and the return of a viscous lubricant, in particular lubricating oil and possibly grease from, or to multiple lubrication points within a printing press, with a Zubringungsabschnitt, for feeding the lubricant to the lubrication points a recirculation section for returning the lubricant and a delivery system for delivering the lubricant from the return section to the delivery section, wherein sensor means are provided for generating oil indicative electrical signals and an electronic computer means adapted to receive them those concerning the oil condition evaluates indicative signals associated with other machine operating data, based on this evaluation an evaluation result is generated, which provides information about the current lubricating performance or the state of wear of the lubricant.

Dadurch wird es auf vorteilhafte Weise möglich, festzustellen, inwieweit das in dem Schmierkreislauf befindliche Schmieröl den für eine zuverlässige Schmierung der entsprechenden Schmierstellen maßgeblichen Anforderungen entspricht. Insbesondere wird es hierdurch möglich, die Dauer der Schmierstoffwechselintervalle auf den tatsächlichen Schmierstoffverschleißzustand abzustimmen und hierdurch einen Sicherheitsgewinn zu erreichen. Der sensorisch ermittelte Schmierstoffverschleißzustand kann mit weiteren Informationen, insbesondere Maschinenbetriebsinformationen verknüpft werden, um das Schmiervermögen und die potentielle Restlaufzeit des Schmierstoffes präzise abzuschätzen.This makes it possible in an advantageous manner to determine the extent to which the lubricating oil in the lubrication circuit corresponds to the relevant requirements for a reliable lubrication of the corresponding lubrication points requirements. In particular, this makes it possible to match the duration of the lubricant change intervals to the actual lubricant wear condition and thereby achieve a safety gain. The sensor-determined lubricant wear condition can be combined with further information, in particular machine operating information be linked to accurately estimate the lubricity and the potential residual life of the lubricant.

Gemäß einer besonders bevorzugten Ausführungsform der Erfindung ist die Sensoreinrichtung derart ausgebildet, dass durch diese mechanische Eigenschaften wie z.B. die Viskosität und Dichte des Schmierstoffes erfasst werden. Die Sensoreinrichtung kann weiterhin derart ausgebildet sein, dass durch diese auch elektrische Eigenschaften (Dielektrizität, Permitivität) des Schmierstoffes erfasst werden.According to a particularly preferred embodiment of the invention, the sensor device is designed such that by these mechanical properties such. the viscosity and density of the lubricant are recorded. The sensor device can furthermore be designed in such a way that it also detects electrical properties (dielectricity, permittivity) of the lubricant.

In einer weitergehenden Sensorausführung oder -ausstattung können über spektroskopische Anaiyseverfahren auch chemische Veränderungen des Schmierstoffes erfasst werden. Beispielsweise können reaktive Veränderungen des Schmierstoffes (z.B. Sulfation, Nitration, Oxidation), der Abbau von Additiven oder das Befüllen mit ungeeigneten Schmierstoffen, der pH-Wert und der Wassergehalt erfasst werden. Weitere Sensorgestaltungen ermöglichen Rückschlüsse auf die Versäuerung des Schmierstoffes oder gestatten über reversible Austauschvorgänge an Oberflächen und Gerüstsubstanzen (z.B. Zeolithe) Aussagen über Veränderungen von Inhaltsstoffen oder den Wassergehalt des Schmierstoffes.In a more extensive sensor design or equipment, chemical changes in the lubricant can also be detected by spectroscopic analysis methods. For example, reactive changes in the lubricant (e.g., sulfation, nitration, oxidation), degradation of additives, or filling with unsuitable lubricants, pH, and water content can be detected. Other sensor designs allow conclusions to be drawn about the acidification of the lubricant or, via reversible exchanges on surfaces and builders (for example zeolites), statements about changes in ingredients or the water content of the lubricant.

Vorzugsweise wird auch die Temperatur von Lagerstellen und des Schmierstoffes ggf. an verschiedenen Messstellen jeweils erfasst. Bei Temperaturüberschreitung können zusätzliche Kühlsysteme aktiviert werden. Weiterhin ist es möglich, die Sensoreinrichtung so auszubilden, dass durch diese die Präsenz von Partikeln, der Öldurchsatz sowie der Öldruck erfasst wird. Die Sensoreinrichtung kann mehrere Sensoren zur Erfassung unterschiedlicher Stoffeigenschaften aufweisen. Diese Sensoren können zu einer Sensorbaugruppe zusammengefasst sein, oder örtlich verteilt jeweils an jenen Stellen der Druckmaschine montiert sein die eine besonders vorteilhafte Erhebung des Messsignals und Funktion der Sensoren ermöglichen.Preferably, the temperature of bearings and the lubricant is optionally detected at different measuring points, respectively. If the temperature is exceeded, additional cooling systems can be activated. Furthermore, it is possible to design the sensor device such that it detects the presence of particles, the oil throughput and the oil pressure. The sensor device can have a plurality of sensors for detecting different material properties. These sensors can be combined to form a sensor module, or be mounted locally distributed in each case at those points of the printing press that allow a particularly advantageous collection of the measurement signal and function of the sensors.

Die so gewonnenen Ölzustaridsinformationen werden gemäß einer besonders bevorzugten Ausführungsform der Erfindung einem Leitstandsrechner zur Verfügung gestellt und dort zumindest temporär abgespeichert. Die Ölzustandsinformationen können einem Betriebsdatenerfassungssystem zur Verfügung gestellt werden, sodass anhand dieser Ölzustandsinformationen eine Planung der weiteren Maschinenbetriebszeit sowie des Schmierstoffwechsels und damit verbunden eine Koordination der Schmierstoffbeschaffung erfolgen kann.According to a particularly preferred embodiment of the invention, the oil starvation information obtained in this way is made available to a central computer and stored there at least temporarily. The oil condition information can be made available to an operating data acquisition system, so that on the basis of this oil state information, a planning of the further machine operating time and the lubricant change and, associated therewith, a coordination of the lubricant procurement can take place.

Es ist möglich, die im Bereich des Leitstandsrechners abgelegten Ölzustandsinformationen auch zu einem externen Diagnosesystem weiterzuleiten oder zumindest diesem Diagnosesystem zum Zugriff zur Verfügung zu stellen. Anhand dieser Ölzustandsinformationen kann dann ein Wartungs- und Materialbereitstellungsplan für die Wartung und Pflege der entsprechenden Druckmaschine oder Druckmaschinenfamilie abgestimmt werden.It is also possible to forward the oil state information stored in the area of the control computer to an external diagnostic system or at least make it available to this diagnostic system for access. On the basis of this oil condition information, a maintenance and material preparation plan for the maintenance and care of the corresponding printing machine or printing press family can then be coordinated.

Es ist möglich, anhand der über die erfindungsgemäß vorgesehenen Sensoren gewonnenen Ölzustandsinformationen eine elektronische Feinabstimmung der Maschineneinstellung herbeizuführen. So ist es möglich, in Abhängigkeit vom Ölzustand den Ölversorgungsdruck an bestimmten Schmierstellen zu erhöhen bzw. abzusenken. Es ist möglich, insbesondere das Rückführsystem in Unterabschnitte zu gliedern, sodass über dieses Untersystem Ölströme mit hohem Verschleißgrad, hoher Verschmutzungsgefahr (z.B. Wassereintrag über die Farbwerkstemperierung), oder hoher Verschmutzungswahrscheinlichkeit von Ölströmen mit geringerem Verschleißgrad zumindest weitgehend getrennt werden.It is possible, based on the oil state information obtained via the sensors provided according to the invention, to bring about an electronic fine-tuning of the machine setting. It is thus possible, depending on the oil condition, to increase or lower the oil supply pressure at certain lubrication points. In particular, it is possible to subdivide the recycle system into subsections so that oil streams with high degree of wear, high risk of contamination (for example introduction of water via the inking unit tempering) or high probability of contamination of oil streams with lower degree of wear are at least largely separated via this subsystem.

Die Umwälzung der derart separat abgegriffenen Ölströme kann dann so erfolgen, dass die weitgehend hochrein zurückgeführten Ölströme für die Wiederversorgung von Lagerstellen vorgesehen sind, bei welchen besonders hohe Anforderungen an die R einheit oder anderweitigen Eigenschaften des Öls bestehen. Insbesondere ist es möglich, Ölrückströme von Wälzlagerzonen separat von Ölströmen aus Getriebezonen zu führen.The circulation of the thus separately tapped oil streams can then be made so that the largely high-purity recirculated oil streams are provided for the re-supply of bearings where particularly high demands on the R unit or other properties of the oil. In particular, it is possible to guide oil return flows of rolling bearing zones separately from oil flows from gear zones.

Es ist möglich, das Schmierstoffsystem so aufzuteilen, dass eine Nachfüllung von Schmierstoff primär in einen Reinölwannenbereich erfolgt und eine Nachfüllung der hinsichtlich der Reinheitserfordernisse weniger anspruchsvollen Maschinenbereiche durch allmählichen Abzug von Schmierstoff aus dem Reinölwannenbereich erfolgt. Es ist möglich, das Schmiersystem so auszubilden, dass eine allmähliche Durchführung des Schmierstoffes aus den Reinbereichen in die verschmutzungsrelevanteren Bereiche und eine finale Abführung des Schmieröls aus diesen Frachtölbereichen erfolgt. Es ist damit insbesondere möglich, einen kontinuierlichen Schmierstoffaustausch abzuwickeln.It is possible to divide the lubricant system so that replenishment of lubricant is primarily to a clean oil pan area and refilling of less demanding machine areas in terms of cleanliness requirements by gradually removing lubricant from the clean oil pan area he follows. It is possible to design the lubrication system in such a way that a gradual passage of the lubricant from the clean areas into the polluting areas and a final discharge of the lubricating oil from these cargo areas. It is thus possible in particular to handle a continuous lubricant exchange.

Gemäß einer besonders bevorzugten Ausführungsform der Erfindung ist es möglich, das Schmieröl in Abhängigkeit von dem erfassten Zustand durch Zugabe von Additiven nachzubessern. Die Zugabe der Additive kann in Abhängigkeit von den Schmierstoffinformationen dosiert werden.According to a particularly preferred embodiment of the invention, it is possible to improve the lubricating oil as a function of the detected state by adding additives. The addition of the additives can be metered depending on the lubricant information.

Das erfindungsgemäße Schmierölsystem eignet sich für Rotationsdruckmaschinen in Form von Bogendruckmaschinen sowie auch Rollendruckmaschinen sowie auch insbesondere für Veredelungs- und anderweitige Papierweiterverarbeitungsmaschinen. Es eignet sich auch zur Koordination des Schmierstoffaustauschs bei einem Maschinenverbund.The lubricating oil system according to the invention is suitable for rotary printing presses in the form of sheet-fed printing presses as well as web-fed printing presses as well as, in particular, for finishing and other paper finishing machines. It is also suitable for coordinating the lubricant exchange in a machine network.

Durch das erfindungsgemäße Konzept wird es möglich, den Ölzustand der Ölumlaufschmierung in der Maschine insgesamt oder insbesondere auch in einzelnen Aggregaten zu erfassen und hierbei insbesondere physikalische und chemische Ölkennparameter durch Einsatz entsprechender Sensoren zu gewinnen. Auf Grundlage des erfindungsgemäßen Konzeptes wird es möglich, die Betriebsdauer des verwendeten Schmiermittels zu maximieren und hierdurch erhebliche Ersparnisse zu erzielen. Gegebenenfalls sind auf Grundlage der Ölanalyse Begrenzungen der Maschinenleistung (z.B. Bogenleistung (B/h), oder die zulässige maximale Geschwindigkeit) zur Schadensvermeidung vorsorglich zu begrenzen.The concept according to the invention makes it possible to detect the oil condition of the oil circulating lubrication in the machine as a whole or, in particular, also in individual units, and in particular to obtain physical and chemical oil characteristic parameters by using appropriate sensors. On the basis of the concept according to the invention, it becomes possible to maximize the service life of the lubricant used and thereby achieve considerable savings. Where appropriate, limits on machine performance (e.g., sheet capacity (B / h), or allowable maximum speed) for avoidance of damage shall be limited as a precaution based on oil analysis.

Die für das erfindungsgemäße Schmierstoffmanagement vorgesehenen Ölzustandssensoren können insbesondere im Ölkreislauf, z.B. in der Ölwanne oder im Rohrsystem angeordnet sein.The oil condition sensors provided for the lubricant management according to the invention can be arranged in particular in the oil circuit, for example in the oil sump or in the pipe system.

Die erfindungsgemäße Sensorik ermittelt vorzugsweise folgende Kenndaten:

  • Mechanische Eigenschaften (z.B. Kompressibilität, Dichte, Viskosität / Viskositätsänderung,
  • optische, insbesondere spektrale Eigenschaften des Schmierstoffes (z.B. zur Ermittlung chemischer Veränderungen des Schmierstoffes sowie der Erfassung des Fremdmedieneintrags),
  • Änderung der elektrischen Eigenschaften (Leitfähigkeit, Dielektrizität, Magnetismus),
  • Temperatur, und gegebenenfalls auch den
  • Füllstand des Ölvorratssystems.
The sensor system according to the invention preferably determines the following characteristic data:
  • Mechanical properties (eg compressibility, density, viscosity / viscosity change,
  • optical, in particular spectral properties of the lubricant (eg for the determination of chemical changes of the lubricant as well as the detection of the foreign media entry),
  • Change of electrical properties (conductivity, dielectric, magnetism),
  • Temperature, and possibly also the
  • Level of the oil reservoir system.

Die Ausgangssignale der Sensorik oder der entsprechenden Sensorfamilie werden vorzugsweise in der Maschinensteuerung und im Bereich der Leitstandserfassung verarbeitet und können hierbei in visuelle und akustische Signale umgewandelt werden, die als solche den Ölzustand beschreiben und gegebenenfalls daraus abgeleitete Wechselintervalle anzeigen. Es ist möglich, Zustände zu erfassen die als abschaltrelevant einzustufen sind, so dass die Maschine zur Schadensvermeidung stillgesetzt werden kann. Die Stillsetzung kann nach einem Abbremskonzept erfolgen das auf eine möglichst geringe mechanische Belastung des aufgrund mangelnder Schmierleistung funktionsbeeinträchtigten oder anderweitig störungsrelevanten Systemabschnitts abzielt. Zusätzlich ist es auch möglich, in die hinsichtlich des Ölzustands erfindungsgemäß erhobenen Informationen zur Betriebsüberwachung der Maschine einzusetzen.The output signals of the sensor system or of the corresponding sensor family are preferably processed in the machine control and in the area of the control station detection and can hereby be converted into visual and acoustic signals which as such describe the oil condition and optionally indicate change intervals derived therefrom. It is possible to record states that are to be classified as relevant for shutdown, so that the machine can be shut down to avoid damage. The shutdown can be carried out according to a braking concept which aims at the lowest possible mechanical load of the function impaired due to lack of lubrication performance or otherwise interference relevant system section. In addition, it is also possible to use in the information regarding the operation of the machine in accordance with the invention with regard to the oil condition.

Es ist möglich, an ausgewählten Zonen der jeweiligen Druckmaschine Sensoren einzusetzen anhand welcher akustische Effekte, sowie mechanische Vibrationseffekte ermittelt werden können. Diese Informationen können ebenfalls in die Ermittlung des Verschleißzustandes des Schmierstoffes Eingang finden.It is possible to use sensors at selected zones of the respective printing press on the basis of which acoustic effects and mechanical vibration effects can be determined. This information can also be used to determine the state of wear of the lubricant.

Durch das erfindungsgemäße Konzept ergeben sich wirtschaftliche Vorteile für den Maschinenbetreiber, da diesem eine optimale Ausnutzung des Schmierstoffpotentiales ermöglicht wird und die relativ großen Ölmengen erst in erheblich längeren Zeitabständen gewechselt werden können. Weiterhin können anhand des erfindungsgemäßen Sensorkonzeptes Schadensfälle rasch erkannt werden. Insbesondere kann über das erfindungsgemäße System vorzugsweise auch festgestellt werden, ob über die Farbwerke der Druckwerke Verunreinigungen und Fremdstoffe in den Schmierölkreislauf gelangen. Das erfindungsgemäße Sensorsystem kann derart an die Maschinensteuerung angebunden sein, dass durch dieses eine automatische Notabschaltung, oder Notbetriebseinleitung und -steuerung ermöglicht wird.The inventive concept results in economic advantages for the machine operator, since this optimal utilization of the lubricant potential is made possible and the relatively large quantities of oil can be changed only at significantly longer intervals. Furthermore, damage events can be detected quickly on the basis of the sensor concept according to the invention. In particular, it can also preferably be determined via the system according to the invention whether impurities and foreign substances enter the lubricating oil circuit via the inking units of the printing units. The sensor system according to the invention can be connected to the machine control such that an automatic emergency shutdown, or emergency operation initiation and control is made possible by this.

Anhand der erfindungsgemäß erhobenen Ölzustandsinformaüonen wird es möglich, Serviceintervalle zeitlich vorteilhaft einzuplanen und insbesondere die Wartungsintervalle auf den tatsächlichen Maschinenbetrieb abzustimmen. Über das erfindungsgemäße Konzept wird eine Ferndiagnose (intern, extern) der Druckmaschine möglich. Weiterhin wird es möglich, die Ölzustandsinformationen zu dokumentieren und den Maschinenbetrieb auch hinsichtlich des Ölzustandes zu protokollieren. Durch das erfindungsgemäße Konzept ergibt sich insgesamt eine verbesserte Ökologie des Druckmaschinenbetriebs und eine bessere Verfügbarkeit der Maschine.Based on the inventively obtained Ölzustandsinformaüonen it becomes possible to schedule service intervals advantageous in time and in particular to tune the maintenance intervals to the actual machine operation. By means of the concept according to the invention, a remote diagnosis (internal, external) of the printing machine becomes possible. Furthermore, it becomes possible to document the oil condition information and to log the machine operation also with regard to the oil condition. The inventive concept results overall in an improved ecology of printing press operation and better availability of the machine.

Es ist möglich, mehrere Druckwerke oder auch Druckmaschinen signaltechnisch und gegebenenfalls auch hinsichtlich des Ölsystems zu vernetzen. Die Ist-Zustände können in Betriebsdatenerfassungssysteme, in Analysesysteme und in Auftragsbearbeitungssysteme weitergeleitet werden und damit eine Optimierung der Servicezeit für ganze Maschinenparksysteme ermöglichen. Grundsätzlich ergibt sich auf Grundlage des erfindungsgemäßen Ansatzes gegenüber der Ermittlung von Wartungsaufträgen lediglich auf Grundlage von Betriebsstundenzählem eine höhere Flexibilität bei der Abstimmung der Ölwechseltermine. Hierdurch ergeben sich ökologische und ökonomische Vorteile insbesondere auf Grundlage einer verbesserten Resourcenschonung .It is possible to network several printing units or printing press signaling technology and possibly also with regard to the oil system. The actual statuses can be forwarded to production data acquisition systems, to analysis systems and to order processing systems, thus enabling an optimization of the service time for entire machine park systems. Basically, on the basis of the approach according to the invention compared to the determination of maintenance orders based solely on operating hours counter results in a higher flexibility in the vote of the oil change dates. This results in ecological and economic advantages, in particular based on an improved resource conservation.

Die Maschinenbetriebsdaten können in ein Ferndiagnosesystem eingebracht werden, sodass eine Maschinenüberwachung auch von einem Spezialdienstleister oder insbesondere von dem Maschinenhersteller und dessen Serviceteam möglich wird.The machine operating data can be incorporated into a remote diagnostic system, so that machine monitoring by a specialist service provider or in particular by the machine manufacturer and his service team is possible.

Anhand der ermittelten Betriebszustände kann auch eine Dokumentation erfolgen, die unter Umständen bei Gewährleistansprüchen Aufschluss über Schadensursachen geben kann. Die erfindungsgemäß zur Erfassung des tatsächlichen Ölzustandes vorgesehenen Sensoren können als E intauch- oder insbesondere auch als Durchflusssensoren ausgebildet sein. Es ist möglich, die Trübung des Öles und die Präsenz etwaiger Partikel auf Grundlage optischer Messsysteme zu ermitteln.On the basis of the determined operating conditions, a documentation can also be provided, which under certain circumstances can provide information on causes of damage in case of warranty claims. The sensors provided according to the invention for detecting the actual oil condition may be embodied as flow sensors or, in particular, also as flow sensors. It is possible to determine the turbidity of the oil and the presence of any particles based on optical measuring systems.

Über die erfindungsgemäßen Sensoren können mechanische Eigenschaften des Schmierstoffes, insbesondere die Viskosität desselben sowie auch elektrische, chemische und optische Flüssigkeitseigenschaften, wie z.B. die Leitfähigkeit bzw. der Metallgehalt ermittelt werden. Durch Überwachung der Maschinenakustik wird es ebenfalls möglich, eine Geräuschanalyse vorzunehmen und hiermit zusätzliche Rückschlüsse auf den Ölzustand, insbesondere das Ausbildungspotential für eine ausreichende tribologische Trennschicht zu ziehen. Als optische Eigenschaften können insbesondere die Trübung und die Partikelzahl je Volumeneinheit ermittelt werden.Mechanical properties of the lubricant, in particular the viscosity thereof, as well as electrical, chemical and optical fluid properties, such as e.g. the conductivity or the metal content are determined. By monitoring the machine acoustics, it is also possible to make a noise analysis and hereby draw additional conclusions about the oil condition, in particular the training potential for a sufficient tribological separation layer. In particular, the turbidity and the particle number per unit volume can be determined as optical properties.

Die erfindungsgemäß vorgeschlagenen Maßnahmen machen es möglich, die Belastung von Schmierölen und Fetten in der Druckmaschine derart zu validieren, dass von fixen Ölwechselintervallen auf individuelle und dem tatsächlichen Gebrauchszustand des Öles (Fettes) Rechnung tragende Ölwechseltermine übergegangen werden kann. Durch das erfindungsgemäße Konzept können eventuell hervortretende Engpässe oder kritische Betriebszustände frühzeitig erkannt und damit vermieden werden.The inventively proposed measures make it possible to validate the burden of lubricating oils and fats in the printing press such that from fixed oil change intervals on individual and the actual use of the oil (fat) bill bearing oil change dates can be transferred. The concept according to the invention allows any emerging bottlenecks or critical operating states to be recognized early and thus avoided.

Gemäß einem besonderen Aspekt der Erfindung wird einerseits der Ölzustand überwacht und andererseits werden maschinenspezifische Daten, z.B. Auftragsdaten, genutzt, um die Belastungshistorie sowie den aktuellen Belastungszustand der Maschine automatisch durch programmgesteuerte elektronische Datenverarbeitung zu ermitteln und Belastungskollektive aufzusummieren bis entsprechende Grenzwerte erreicht sind. Dies ermöglicht eine besonders effektive Fernwartung und Fernüberwachung, es unterstützt auch die Planarbeit von Serviceintervallen und weitere für den Maschinenbetrieb maßgebliche Hintergrundarbeiten. Besonders der spezielle Zustand und Nutzungshistorie der einzelnen Komponenten, z.B. Zwischentrockner-, Laufleistung und vieles mehr können in erfindungsgemäß besonders vorteilhafter Weise in die Ermittlung der spezifischen Belastung eingearbeitet werden, z.B. durch Temperaturerfassung. Somit kann man von starren Wechselzeiten abkommen und zu individuell der tatsächlichen Belastung angepassten Wechselintervallen (Ökologie) gelangen. Die Erkennung von z.B. Wasser im Schmiermittel (z.B. von der Farbwalzentemperierung) oder von Spänen (z.B. durch Bauteilschäden oder mangelhafte Reinigung bei Inbetriebnahme) ist hier nur ein beispielhafter Ausschnitt der Möglichkeiten.According to a particular aspect of the invention, on the one hand, the oil condition is monitored and, on the other hand, machine-specific data, eg order data, are used to automatically determine the load history and the current load status of the machine by program-controlled electronic data processing to determine and sum up load collectives until appropriate limits are reached. This enables particularly effective remote maintenance and monitoring, it also supports the planning of service intervals and other background work relevant to machine operation. In particular, the special condition and usage history of the individual components, eg intermediate dryer, mileage and much more can be incorporated in accordance with the invention particularly advantageously in the determination of the specific load, for example by temperature detection. Thus, one can get away from rigid change times and arrive at individually adapted to the actual load change intervals (ecology). The detection of, for example, water in the lubricant (eg from the ink roller tempering) or chips (eg due to component damage or inadequate cleaning during commissioning) is just one example of the possibilities.

Die Visualisierung von Ölbelastungszuständen sowie die Planung von Wechselzeiten sowie die Fernüberwachung von Druckanlagen wird durch das erfindungsgemäße Konzept möglich. Über die erfindungsgemäße Technologie sind auch die Ölbremsen der Antriebe überwachbar (insbesondere bei Großformat usw.). Bei Großanlagen, z.B. Zeitungsrotationsdruckmaschinen kann in der Vorausschau der zukünftigen Auftragsstruktur bereits besser abgeschätzt werden, wann entsprechende Ölwechselintervalle vorgezogen und durch bestimmte Betriebszustände (Absenkung von Temperatur und Laufgeschwindigkeit, Teilmengenzwischenaustausch, Nachfüllung) Anlagen kosten- und verschleißoptimiert und verzögert gewartet werden können.The visualization of oil stress conditions and the planning of change times and the remote monitoring of printing systems is possible by the inventive concept. About the technology of the invention, the oil brakes of the drives are monitored (especially in large format, etc.). In large plants, e.g. Newspaper rotary presses can already be better estimated in the forecast of the future order structure when appropriate oil change intervals are brought forward and because of certain operating conditions (lowering of temperature and running speed, partial quantity interchange, refilling) systems can be maintained cost and wear optimized and delayed.

Es ist möglich, die Sensoren so zu gestalten, dass über diese auch spektroskopische Eigenschaften des Schmierstoffes erfasst werden können. Die spektroskopische Analyse des Schmierstoffes kann auf ausgewählte, relevante Spektralbereiche oder Wellenlängenbereiche beschränkt werden. Es ist möglich, dem Schmierstoff Substanzen beizumengen deren Präsenz über die Sensoren erfasst werden kann. Über die Sensoren kann damit insbesondere geprüft werden, ob zulässige Schmierstoffe Anwendung finden.It is possible to design the sensors in such a way that they can also detect spectroscopic properties of the lubricant. The spectroscopic analysis of the lubricant can be restricted to selected, relevant spectral ranges or wavelength ranges. It is possible to add to the lubricant substances whose presence can be detected via the sensors. In particular, it can be checked via the sensors whether permissible lubricants are used.

Über Ferndiagnoselogistik kann automatisch die entsprechende Ölmenge und Ölart logistisch zur Verfügung gestellt, und die Wartung vorgeplant werden. Über die Übermittlung des Lastkollektives kann auch eine Schadensverfolgung vorgenommen werden (z.B. zur Überprüfung von Gewährleistungsansprüchen).Remote diagnostics logistics can automatically provide the appropriate oil quantity and type of oil logistically, and pre-arrange maintenance. The transmission of the load collective can also be used to track damage (for example, to check warranty claims).

Durch das erfindungsgemäße Konzept wird eine an die aktive Maschinenbelastung angepasste zentrale Verbrauchsschmierung ermöglicht, z.B. Fettverbrauchsschmierung am Ausleger und Ölzentralschmierung mit gleitenden und der tatsächlichen Maschinenbelastung angepassten Wechselintervallen. Insbesondere lässt sich der Temperatureinfluss mittels Stapeltemperatursensor an der Auslage erfassen und in die Fettdosierung einrechnen. Auf Grundlage des erfindungsgemäßen Konzeptes wird es möglich, die Schmierstoffzufuhr zu verschiedenen Systemabschnitten auf Grundlage einer sensorgestützten Modell- oder Approximationsrechnung individuell abzustimmen und Überdosierungen zu vermeiden. Zudem können die Nachspeisezeitpunkte optimiert festgelegt werden.The concept according to the invention enables a central consumption lubrication adapted to the active machine load, e.g. Grease lubrication on the boom and oil central lubrication with sliding and the actual machine load adapted replacement intervals. In particular, the temperature influence can be detected by means of stack temperature sensor on the display and included in the fat dosage. On the basis of the concept according to the invention, it becomes possible to tailor the lubricant supply to different system sections on the basis of a sensor-based model or approximation calculation and to avoid overdoses. In addition, the make-up times can be set optimized.

Hinsichtlich eines Verfahrens zur Abwicklung der Schmierstoffversorgung wird die eingangs angegebene Aufgabe erfindungsgemäß auch gelöst durch ein Verfahren Schmierstoffversorgungsverfahren gemäß Patentanspruch 24. Vorteilhafte Ausgestaltungen dieses Verfahrens sind Gegenstand der Unteransprüche.With regard to a method for processing the lubricant supply, the object specified above is also achieved by a method lubricant supply method according to claim 24. Advantageous embodiments of this method are the subject of the dependent claims.

In Figur 2 ist ein Schmiersystem für eine Druckmaschine dargestellt, das mehrere Druckwerke DW1 ... DW6 umfasst. Die Druckmaschine umfasst weiterhin einen Anleger A1 und einen Ausleger A2. Die Lagerstellen der in den jeweiligen Druckwerken DW1 ... DW6 vorgesehenen Druck-, Gummi-, und Plattenzylinder sowie gegebenenfalls anderweitige abgedichtete Lagerstellen werden über einen ersten Schmierkreis SK1 mit Schmieröl versorgt, das aus einem Behälter B1 abgezogen wird:In FIG. 2 a lubrication system for a printing press is shown, which comprises several printing units DW1 ... DW6. The printing machine further comprises a feeder A1 and a boom A2. The bearings of the provided in the respective printing units DW1 ... DW6 pressure, rubber, and plate cylinder and possibly other sealed bearings are supplied via a first lubrication circuit SK1 with lubricating oil, which is withdrawn from a container B1:

Die Versorgung der übrigen Lagerstellen der Druckwerke DW1 ... DW6 erfolgt über einen zweiten Schmierkreis SK2, dessen Schmieröl aus einem zweiten Behälter B2 bezogen wird. Die Versorgung des Anlegers A1 und des Auslegers A2 erfolgt schließlich über einen dritten Schmierkreis SK3, dessen Schmierstoff aus einem Behälter B3 bezogen wird. Die Umwälzung des Schmierstoffes durch den jeweiligen Schmierkreis SK1, SK2, SK3 bzw. die Zuführung zu dem jeweiligen Maschinenabschnitt erfolgt unter Einbindung von Schmiermittelpumpen P1, P2 sowie P3' und P3".The supply of the other bearings of the printing units DW1 ... DW6 via a second lubricating circuit SK2, the lubricating oil from a second container B2 is obtained. The supply of the feeder A1 and the arm A2 finally takes place via a third lubrication circuit SK3, whose lubricant is obtained from a container B3. The circulation of the lubricant through the respective lubrication circuit SK1, SK2, SK3 or the supply to the respective machine section takes place with the involvement of lubricant pumps P1, P2 and P3 'and P3 ".

In die jeweiligen Schmierkreise SK1, SK2, SK3 sind Sensoren Z1 ... Z12 eingebunden, über welche verschiedene, jeweils hinsichtlich des Verschleißzustandes des Schmieröls indikative Informationen erhoben werden können. Die über die Sensoren Z1 ... Z12 erhobenen informationen werden der Auswertungsschaltung 2 zugeführt und durch diese vorverarbeitet.In the respective lubrication circuits SK1, SK2, SK3 sensors Z1 ... Z12 are integrated, via which various, each indicative of the wear condition of the lubricating oil information can be collected. The information collected via the sensors Z1... Z12 is fed to the evaluation circuit 2 and preprocessed by it.

Über die Auswertungsschaltung 2 können die Sensorsignale so aufbereitet werden, dass diese vom zentralen Maschinenleitstand 3 aus abgefragt und weiterverarbeitet werden können. Das hier gezeigte Druckmaschinenschmiersystem kann so betrieben werden, dass im Falle störungsbedingt in dem jeweiligen Schmierkreis SK1, SK2, SK3 auftretender Ölbelastungen über die Sensoren Z5 bis Z12 eine Umleitung bzw. Ableitung des Öls in ein Restölbehältnis B4 veranlasst werden kann.About the evaluation circuit 2, the sensor signals can be processed so that they can be queried from the central machine control station 3 and further processed.

Der Behälter B2 wiederum kann durch den Behälter B1 nachgefüllt werden. Hierdurch wird es möglich, in den einzelnen Systemabschnitten des Druckmaschinenschmiersystems jeweils hinreichend hohe Ölqualitäten sicherzustellen und eine Rückführung von Verunreinigungen aus verschmutzungsintensiveren Systemabschnitten in sensiblere Systemabschnitte zu vermeiden.By not shown here valve and bridging pipe facilities, it is possible to automatically derive oil from the container B3 into the container B4 on reaching certain oil conditions and make a refill from the container B2. The container B2 in turn can be refilled by the container B1. This makes it possible to ensure in the individual system sections of the printing machine lubrication system respectively sufficiently high oil qualities and to avoid a return of impurities from more polluting system sections in more sensitive system sections.

In die einzelnen Schmierkreise SK1, SK2, SK3 können Filtereinrichtungen eingebunden sein, durch welche zusätzlich etwaige in diese Schmierkreise gelangende Verunreinigungen abgefangen werden können. Der Druck vor dem jeweiligen Filter und ggf. der hierbei erfolgende Volumendurchsatz, kann als Information über den Filterzustand und Schmutzanfall in dem Systemabschnitt interpretiert werden. Das hier gezeigte Druckmaschinenschmiersystem kann auch so ausgeführt sein, dass dieses nur zwei, oder anderweitig geteilte Ölqualitätsabschnitte aufweist. Es kann auch so ausgebildet sein, dass dieses weitere Ölqualitätsabschnitte umfasst.In the individual lubrication circuits SK1, SK2, SK3 filter devices can be integrated, by which any possible entering into these lubrication impurities can be intercepted. The pressure in front of the respective filter and, if appropriate, the volume throughput that takes place in this case, can be interpreted as information about the filter condition and accumulation of dirt in the system section.

  • Ambient temperature / humidity, cold start of the machine and the like,
  • Job data, such as order size, job structure, etc.
  • Condition of the filter systems (filter quality).

Anhand der vorgenannten erhobenen und elektronisch, datentechnisch und automatisch verarbeiteten Maschinenbetriebsdaten und der ermittelten Verschleißzustände des Schmierstoffes kann der tatsächliche Verschleißzustand der Druckmaschine oder zumindest der Betriebsmittel präziser beschrieben werden. Hierdurch ergibt sich als Vorteil, dass keine festen Wechselintervalle für Öle (Fette, Schmiermittel) bestehen, sondern die Maschine nach Gebrauchszustand/Verschleiß des Öles/Fettes gewartet wird. Hierdurch wird eine frühzeitige Schadenserkennung bzw. Schadensverhinderung möglich. Durch Detektierung von Wasser (z.B. Farbwerkstemperierung) bzw. Späne, Gleitlager, Verzahnung oder dergleichen.Based on the aforementioned collected and electronically, data technology and automatically processed machine operating data and the determined wear conditions of the lubricant, the actual state of wear of the printing press or at least the resources can be described more precisely. hereby results in the advantage that there are no fixed change intervals for oils (greases, lubricants), but the machine is maintained after use condition / wear of the oil / fat. As a result, early damage detection or damage prevention is possible. By detection of water (eg inking temperature control) or chips, plain bearings, teeth or the like.

Bei Auftreten von Störinformationen kann eine Absetzung einer visuellen (Leitstand) akustischen Warnmeldung und - je nach ermitteltem, oder aufgrund der Signale erwartetem Schädigungsgrad - eine Einleitung eines automatischen Maschinenstopps erfolgen. Weiterhin kann eine frühzeitige Planung von Wechsel/Serviceintervallen, z.B. mehrere Maschinen gleichzeitig über einen Wartungseinsatz erfolgen und hierdurch eine Ressourcenverschwendung durch frühzeitigen Ölwechsel vermieden werden.If interference information occurs, a visual (control room) acoustic warning message can be issued and an automatic machine stop can be initiated, depending on the degree of damage determined or due to the signals due to the signals. Furthermore, early planning of change / service intervals, e.g. several machines simultaneously via a maintenance operation and thereby a resource waste by early oil changes are avoided.

Die Einbindung von maschinenreievanten Daten kann über den Leitstand bzw. Netzwerke, erfolgen. Als Ermittlungsgrundlagen für die Maschinenbelastung können Daten insbesondere die Maschinengeschwindigkeit, Daten des Bogenzählers, Trocknerlaufzeiten (z.B. UV-Zwischentrockner) herangezogen werden. Aus diesen Daten kann die Belastung der Druckwerke modelliert werden. Die ergänzende Ermittlung der Druckwerksbelastung kann weiterhin auch durch Temperaturmessungen, insbesondere direkte Öltemperaturmessung erfolgen.The integration of machine-relevant data can be done via the control center or networks. As a basis for determining the machine load data can be used in particular the machine speed, data of the sheet counter, dryer run times (for example, UV intermediate dryer). From this data, the load of the printing units can be modeled. The additional determination of the printing unit load can also be done by temperature measurements, in particular direct oil temperature measurement.

Es ist möglich, das Temperaturprofil der Umgebung in der die Maschine gelaufen ist, die Farbbelegung, und eingesetzte Farbwerke (Druckwerke), d.h. drucktechnisch vorliegende Werte die für den Belastungszustand der Maschine relevant sind, z.B. hohe Farbdichte, Nass- oder Trockenoffset, Temperatur der Farbwerktemperierung, Farbwerkseinstellungen usw., aufzuzeichnen und einem Berechnungsmodel zur Ermittlung der Maschinenbelastung zugrundezulegen.It is possible to know the temperature profile of the environment in which the machine has run, the color assignment, and inking units (printing units) used, i. typographical values relevant to the load condition of the machine, e.g. high color density, wet or dry offset, temperature of the inking unit temperature control, inking unit settings, etc., and to use a calculation model to determine the machine load.

Die hinsichtlich des Ölzustandes erfassten Informationen und die Informationen über den Maschinenbetrieb an sich, können zur wechselseitigen Verifikation und Erhöhung der Aussagekraft der Qualitätsermittlung des Schmierstoffes herangezogen werden. Die Öl-Sensorinformationen können sowohl als Grundlagen, als auch Kontroll- und Korrekturfaktoren für ein ermitteltes Belastungsprofil fungieren.The information acquired with regard to the oil condition and the information about the machine operation per se, can be used for mutual verification and increasing the significance of the quality determination of the lubricant become. The oil sensor information can serve as a basis as well as control and correction factors for a determined load profile.

Es können je nach Maschinengröße ein oder mehrere Sensoren eingesetzt werden, z.B. im Öltank oder vor oder nach dem Filter. Dadurch kann auch die Qualität der Ölfilterung bzw. des Filters festgestellt und dessen Ausfall oder Wechsel definiert werden.Depending on the size of the machine, one or more sensors may be used, e.g. in the oil tank or before or after the filter. As a result, the quality of the oil filtering or the filter can be determined and its failure or change can be defined.

Bei größeren Maschinen kann eine Absicherung pro Druckwerk sinnvoll sein, um eine individuelle Erfassung vorzunehmen. Über Schnittstellen ist vorzugsweise eine Maschinenüberwachung zentral, z.B. über den Vertriebspartner oder im Werk selbst (zentraler Service) möglich und im Schadensfall eine Belegung des Ist-/Sollzustandes über längere Zeiträume durchführbar, z.B. über Datenspeicherung. Sinnvoll kann die zusätzliche Überwachung des Öldrucks im Kreislauf als vorgegebene Minimalgröße sein (Sicherheitsschaltung).In the case of larger machines, a safeguard per printing unit can be useful in order to carry out an individual acquisition. Through interfaces, machine monitoring is preferably central, e.g. via the distribution partner or in the factory itself (central service) possible and in case of damage an assignment of the actual / nominal state over longer periods of time feasible, e.g. about data storage. It makes sense to have the additional monitoring of the oil pressure in the circuit as a predetermined minimum size (safety circuit).

Vorzugsweise sind Verknüpfungen der Maschinensteuerung, dem Leitstand bzw. der Schnittstelle und zentralen Schmierstoffüberwachung vorgesehen. Die Erfindung richtet sich nicht nur auf die Verwendung eines Ölzustandssensors an sich sondern insbesondere auch auf dessen intelligente Einbindung in das Kontrollsystem einer Druckmaschine zur Überwachung und auch zur besseren Nutzung der eingesetzten Schmierstoffe, insbesondere des Umlauföles bei Bogen- und Rollenmaschinen und deren Servicevernetzung. Die erfindungsgemäßen Sensoren können auch für die Temperaturerfassung, z.B. insbesondere für eine Ölvortemperierung genutzt werden. Die zulässigen, oder optimalen Laufgeschwindigkeiten während der Vorheizphase können anhand der Ölzustandsinformationen begrenzt, bzw. ermittelt werden. Anhand der durch die erfindungsgemäßen Sensoren generierten Informationen kann eine Freigabesperrung bestimmter Maschinengeschwindigkeiten bei kritischen Ölzuständen erfolgen, z.B. um bei nicht mehr guten Ölverhältnissen Restauflagen noch abzudrucken.Preferably, links of the machine control, the control station or the interface and central lubricant monitoring are provided. The invention is directed not only to the use of an oil condition sensor per se but also in particular to its intelligent integration into the control system of a printing press for monitoring and also for better use of the lubricants used, in particular the circulating oil in sheetfed and web presses and their service networking. The sensors of the invention may also be used for temperature sensing, e.g. be used in particular for an oil preheating. The allowable or optimal run speeds during the preheat phase may be limited or determined based on the oil condition information. On the basis of the information generated by the sensors according to the invention, a release lock of certain machine speeds can take place at critical oil conditions, e.g. in order to print remaining copies if the oil conditions are no longer good.

Durch Istwerterfassung des Ölzustandes (Sensor) und rechnerische Verarbeitung und der weiteren Belastungsdaten der Maschine, bzw. auch drucktechnischer Daten, die in ein Belastungskollektiv der Maschine umgerechnet werden (wie z.B. bei Wälzlagerberechnungen) kann in vorteilhafter Weise die Zeit bis zum nächsten Ölwechselintervall vorausschauend berechnet bzw. prognostiziert und ggf. visuell am Leitstand graphisch anschaulich angezeigt werden, d.h. wie lange kann noch gedruckt werden bis zum nächsten Wechselintervall. Es ist möglich, das Datenverarbeitungssystem so zu gestalten, dass bei der Festlegung der Maschinenbetriebsparameter für einen bevorstehenden Druckauftrag Angaben errechnet werden, die als solche die Güte der gewählten Prozessparameter beispielsweise hinsichtlich des Ölverbrauchs, sowie der anderweitigen Maschinenbelastung anzeigen und ggf. alternative und wirtschaftlichere Konfigurationsmöglichkeiten aufzeigen und vorschlagen.By actual value acquisition of the oil condition (sensor) and computational processing and the further load data of the machine, or also pressure-technical data, which are converted into a load collective of the machine (such as in rolling bearing calculations) can advantageously calculated the time to the next oil change interval predictive and predictive and visually displayed visually graphically graphically, ie how long can be printed until the next change interval. It is possible to design the data processing system so that when determining the machine operating parameters for an upcoming print job information is calculated, indicating as such the quality of the selected process parameters, for example in terms of oil consumption, and the other machine load and possibly alternative and more economical configuration options and suggest.

Diese Prognose kann beispielsweise durch Verringerung der Maschinengeschwindigkeit oder Abschaltung von Zwischentrocknern oder vom Bediener beeinflusst werden, d.h. reduziert man die Geschwindigkeit kann gegebenenfalls länger gedruckt werde bis zum nächsten Intervall.This prognosis can be influenced, for example, by reducing the machine speed or switching off intermediate dryers or by the operator, i. if you reduce the speed, you can print longer if necessary until the next interval.

Durch Displayeinrichtungen kann der Zustand der Druckmaschine oder des gesamten Maschinenparks graphisch besonders anschaulich visualisiert werden und Warnmeldungen erzeugt werden.By means of display devices, the state of the printing press or of the entire machine park can be graphically visualized in a particularly vivid manner and warning messages can be generated.

Die Überwachung der Filterelemente kann durch die Ölzustandssensorik erfolgen und so kann frühzeitig deren Verschmutzungstrend als des Mediums bzw. der Filter virtuell signalisiert werden bzw. für Wartungszwecke an die Maschinenzentrale oder sogar per Datentransfer an das Werk gemeldet werden (Früherkennung von Maschinenschäden, oder Serviceplanung).The monitoring of the filter elements can be done by the oil condition sensor and so early pollution trend as the medium or the filter can be virtually signaled or reported for maintenance purposes to the machine center or even by data transfer to the factory (early detection of machine damage, or service planning).

Es können auch Hydrobremsen (Ölhydraulikbremsen, z.B. Hydrobremsen aus dem Bereich des Antriebszugs der maschine in die Ölüberwachung eingebunden sein (Ölhydraulik).Hydro brakes (oil hydraulic brakes, for example hydraulic brakes from the area of the drive train of the machine can also be integrated in the oil monitoring (oil hydraulics).
