Abstract
Description
Die Erfindung betrifft ein Verfahren und eine Vorrichtung zum Betrieb einer Temperiereinrichtung im Farbwerk oder Feuchtwerk einer Offsetdruckmaschine.The invention relates to a method and a device for operating a Temperature control device in the inking unit or dampening unit of an offset printing machine.
Offsetrotationsdruckmaschinen für Nass- und Trockenoffsetdruck werden in der
Konfiguration von Bogen- und Rollendruckmaschinen ausgeführt. In beiden
Maschinenformen sind Farbwerke zum Auftrag von Druckfarbe vorgesehen. Zur
Beeinflussung des Druckprozesses werden diese Farbwerke mit einer so
genannten Farbwerktemperierung versehen. Die Farbwerktemperierung erlaubt
es, die in dem Farbwerk verarbeitete Druckfarbe während des Druckprozesses
nach Bedarf aufzuheizen oder abzukühlen.
Bekannt sind auch Temperiereinrichtungen für Lackumlaufsysteme oder
Lackwerktemperierung in Beschichtungseinrichtungen von
Veredelungsmaschinen oder für die so genannte Inlinelackierung in Verbindung
mit Offset- und Flexodruckmaschinen. Auch hier können die Druckmaschinen in
Form von Bogen- oder Rollendruckmaschinen ausgeführt sein.
Temperiereinrichtungen sind auch für Feuchtwerke an Offsetdruckmaschinen
bekannt geworden.Offset rotary printing machines for wet and dry offset printing are configured in the configuration of sheet and web printing machines. In both machine forms, inking units are provided for the application of printing ink. In order to influence the printing process, these inking units are provided with a so-called inking unit temperature control. The inking unit temperature control allows the printing ink processed in the inking unit to be heated or cooled as required during the printing process.
Temperature control devices for coating circulation systems or coating unit temperature control in coating devices of finishing machines or for the so-called inline coating in connection with offset and flexographic printing machines are also known. Here, too, the printing machines can be designed in the form of sheet-fed or web-fed printing machines.
Temperature control devices have also become known for dampening units on offset printing machines.
Die Temperiereinrichtungen werden häufig nach dem Wärmetauscherprinzip ausgeführt. Dabei wird vorzugsweise durch das Innere einer der Walzen des Farbwerkes oder der Beschichtungseinrichtung ein so genanntes Temperiermedium geleitet. Als Temperiermedium wird ein Flüssigkeitsmedium in einem offenen oder geschlossenen Temperierkreislauf eingesetzt. Das Temperiermedium kann zum heizen oder zum kühlen oder zum heizen und kühlen eingesetzt werden. Das Temperiermedium wird über ein Kälteaggregat beispielsweise mittels eines Wärmetauschers gekühlt bzw. über ein Heizelement oder einen Wärmetauscher beheizt. Die Temperatursteuerung und Temperatursensorik in der jeweiligen Druckmaschine oder in der Beschichtungseinrichtung erfolgt durch Temperaturanpassung des Mediums oder die Menge des Durchflusses.The temperature control devices are often based on the heat exchanger principle executed. It is preferably through the interior of one of the rollers Inking unit or the coating device a so-called Temperature control medium. A liquid medium is used as the temperature control medium used in an open or closed temperature control circuit. The Temperature control medium can be used for heating or cooling or for heating and be used cool. The temperature control medium is via a cooling unit cooled, for example by means of a heat exchanger or via a Heated element or a heat exchanger. The temperature control and Temperature sensors in the respective printing press or in the Coating is done by adjusting the temperature of the medium or the amount of flow.
Das Temperiermedium besteht aus einer Mischung von Wasser und Zusätzen zum Schutz des Temperiersystemes in der Druckmaschine. Die Zusätze dienen vor allem dem Rostschutz. Es werden aber auch andersartige Zusätze verwendet.The temperature control medium consists of a mixture of water and additives to protect the temperature control system in the printing press. The additives serve especially the rust protection. But there are also other types of additives used.
Das Temperiermedium wird in der Regel nach längerem Gebrauch durch die Vorgabe von festen Wechselintervallen, d.h. abhängig von der Einsatzzeit, ausgetauscht. Möglich ist es aber auch, nach Stillsetzung der Druckmaschine und Öffnung des Temperiersystems, mittels manueller Kontrolle des pH-Wertes oder eines speziell gewonnenen Leitwertes den Zustand des Temperiermediums zu ermitteln und dieses z.B. bei Unterschreitung eines minimalen Wertes an Korrosionsschutzmittel aufzufrischen oder auszutauschen.The temperature control medium is usually replaced by the Specification of fixed change intervals, i.e. depending on the operating time, replaced. However, it is also possible after the printing machine has been shut down and opening of the temperature control system by means of manual control of the pH value or a specially obtained guide value the state of the To determine the temperature control medium and this e.g. when falling below one minimum value of corrosion protection agent or exchange.
Wichtig ist, dass es bei nicht eingehaltenen Wechselintervallen bzw. nicht durchgeführtem Austausch des Temperiermediums oder bei Nichtbeachtung der Minimalwerte insbesondere durch Korrosion zu erheblichen Maschinenschäden kommen kann. Bei nachlassender Wirkung des Korrosionsschutzes werden häufig Dichtringe leck oder es können gefährdete Stellen korrodieren, wodurch es ebenfalls zu Leckagen kommt. Dabei kann das Temperiermedium im Bereich der Maschinengetriebe in das Schmieröl des Maschinenantriebes gelangen und so dessen Funktion mindern oder sogar ganz außer Kraft setzen.It is important that the change intervals are not met or not carried out exchange of the temperature control medium or in case of non-observance the minimum values, particularly due to corrosion Machine damage can occur. If the effect of the Corrosion protection will often leak sealing rings or it can endanger Correct spots, which also leads to leakages. It can Temperature control medium in the area of the machine gear in the lubricating oil of the Machine drive and thus reduce its function or even override entirely.
Aufgabe der Erfindung ist es daher eine Vorrichtung und ein Verfahren zu schaffen, das in Druckmaschinen mit Temperiereinrichtungen Schäden durch austretendes Temperiermedium sicher verhindert.The object of the invention is therefore a device and a method create damage in printing machines with temperature control devices escaping tempering medium reliably prevented.
Die Aufgabe wird nach den Merkmalen der Ansprüche 1 und 4 gelöst. The object is achieved according to the features of claims 1 and 4.
Im Temperierkreislauf wird maschinenseitig und/oder aggregateseitig ein Detektor bzw. Sensor, beispielsweise eine pH-Wert-Sonde und/oder eine Leitwertsonde in Abhängigkeit des eingesetzten Temperiermediums eingesetzt. Der Detektor bzw. Sensor erfasst die Zusammensetzung des Temperiermediums und berücksichtigt dabei dessen Inhaltsbestandteile. Dies betrifft alle Substanzen in Form etwa von Schutzmittel, z.B. Korrosionsschutzmittel, und auch Wasser im Rahmen von deren jeweils bestimmten Mischungsverhältnissen.In the temperature control circuit, the machine side and / or the unit side Detector or sensor, for example a pH value probe and / or a Conductivity probe used depending on the temperature control medium used. The detector or sensor detects the composition of the Tempering medium and takes into account its content components. This affects all substances in the form of protective agents, e.g. Anticorrosive, and also water as part of their respective certain mixing ratios.
Der Sensor misst ständig oder zyklisch den Istwert im Temperiermedium und vergleicht über eine Steuerung den eingegebenen erforderlichen Sollwert. Der Sollwert ist in der Maschinensteuerung abspeicherbar und kann von Herstellerseite vorgegeben sein. Der Sollwert kann aber auch betriebsbedingt vorgegeben und vom Bedienpersonal eingegeben und abgespeichert werden, z.B. je nach lokaler Wasserqualität. Bei Unterschreitung des Sollwertes erfolgt eine entsprechende Fehlermeldung. Die erforderliche Steuerung kann z. B. im Maschinenleitstand oder auch im Temperiergerät installiert werden. Eine akustisch oder optische Anzeige der Fehlermeldung kann zusätzlich erfolgen. Gleichzeitig wird der Wert protokolliert oder über Datenaustausch an das Servicezentrum oder den Maschinenhersteller weitergegeben.The sensor continuously or cyclically measures the actual value in the temperature control medium and compares the required setpoint entered via a controller. The The setpoint can be saved in the machine control and can be from Manufacturer's side. The setpoint can also be operational specified and entered and saved by the operating personnel, e.g. depending on the local water quality. If the value falls below the setpoint a corresponding error message. The required control can e.g. B. in Machine control center or installed in the temperature control unit. A The error message can also be displayed acoustically or optically. At the same time the value is logged or via data exchange to the Service center or passed on to the machine manufacturer.
Je nach Art der Fehlermeldung kann bei der nächsten zyklischen Wartung das
Temperiermedium dann ausgetauscht oder durch Zugabe von Schutzmittel
wieder aufgefrischt werden. Außerdem kann zusätzlich über einen
Drucksensor, z.B. einen Druckschalter, das Temperiersystem hinsichtlich
Dichtigkeit bzw. Füllstand geprüft und damit das Temperiersystem auf
Leckagen des Temperiermedienkreislaufes überwacht werden. Auf diese Weise
wird vor allem ein unkontrollierter Austritt von Temperiermedium innerhalb der
Druckmaschine erkannt.
So kann die Qualität des Temperiermediums, insbesondere im Hinblick auf die
Qualität des Schutzes gegen Rost, Bakterien, Kalk usw., aktiv überwacht
werden. Depending on the type of error message, the temperature control medium can then be replaced during the next cyclical maintenance or refreshed by adding protective agent. In addition, the temperature control system can also be checked for leaks or fill level via a pressure sensor, for example a pressure switch, and the temperature control system can thus be monitored for leaks in the temperature control medium circuit. In this way, above all, an uncontrolled escape of temperature control medium within the printing press is recognized.
In this way, the quality of the temperature control medium, particularly with regard to the quality of protection against rust, bacteria, lime, etc., can be actively monitored.
Der Aufwand der hierzu eingesetzten Komponenten ist im Hinblick auf den Umfang der diesbezüglich möglichen Maschinenschäden relativ gering. Ein Schaden an der Druckmaschine infolge des Eindringens von Temperiermedium in den Ölkreislauf der Druckmaschine kann auf diese Weise gänzlich verhindert oder doch wenigstens frühzeitig erkannt werden.The effort of the components used for this is with regard to the The scope of possible machine damage is relatively small. On Damage to the printing press due to the penetration of the temperature control medium in the oil circuit of the printing press can be completely prevented in this way or at least be recognized early.
Bei größeren Druckanlagen kann Schutzmittel z.B. über Dosierpumpen mit Vorratsbehälter je nach dem Messwert des Sensors auch aktiv zudosiert werden. Durch die Protokollierung der Messwerte ist bei Maschinenschäden eine aktuelle Bestandsaufnahme über den Wartungszustand für den Maschinenhersteller möglich. Dies kann Einfluss auf Garantiefragen haben. Einfache Servicearbeiten an den Temperiereinrichtungen werden nun über ein Diagnosesystem, auch ein Ferndiagnosesystem, möglich. Feste und zeitlich terminierte und damit auch teure Wechselintervalle können entfallen. Es ist auch eine Trendanzeige bzgl. Hinweisen zur vorbeugenden Wartung möglich. Zusätzlich kann bei offenen Systemen mittels eines so genannten Trübungssensors die bakterielle Verschmutzung des Mediums erfasst werden.With larger printing systems, protective agents e.g. via dosing pumps with Storage containers are also actively metered in depending on the measured value of the sensor become. By logging the measured values is in case of machine damage a current inventory of the maintenance status for the Machine manufacturer possible. This can affect warranty issues. Simple service work on the temperature control devices are now carried out via a Diagnostic system, also a remote diagnostic system, possible. Fixed and timed Scheduled and therefore expensive change intervals can be omitted. It is A trend display with information on preventive maintenance is also possible. In addition, open systems can use a so-called Turbidity sensor the bacterial contamination of the medium can be detected.
Das Temperiermedium wird aktiv bezüglich der noch vorhandenen Korrosionsschutzwirkung und der aufgelaufenen betrieblichen Verschmutzung überwacht. Feste Wechselintervalle sind ökologisch wenig sinnvoll, da nicht der tatsächliche Gebrauchszustand des Temperiermediums erfasst wird.The temperature control medium becomes active with regard to the still existing Corrosion protection effect and accumulated operational pollution supervised. Fixed change intervals are not ecologically sensible, because not the actual condition of use of the temperature control medium is recorded.
Vorteilhaft an der Erfindung ist, dass eine bedarfsgerechte Wartung mittels Ferndiagnose oder über Datentransfer möglich wird. Der Zustand des Temperiersystems kann jederzeit durch Anzeige am Leitstand überwacht werden. Die Dokumentation des Istzustandes des Temperiermittels, auch in Bezug auf die geforderte Wartung der Druckmaschine kann bei der Analyse von Schadensfällen und Beurteilung von Garantieansprüchen verwendet werden. Für die Erhaltung des Maschinenzustandes ist eine vorsorgende Wartung möglich. The advantage of the invention is that maintenance is tailored to the needs Remote diagnosis or data transfer is possible. The state of the Temperature control systems can be monitored at any time by display on the control center become. Documentation of the actual condition of the temperature control agent, also in With regard to the required maintenance of the printing press, the analysis of Damage cases and assessment of warranty claims can be used. Preventive maintenance is required to maintain the machine condition possible.
Es sind keine manuellen Kontrollarbeiten mehr notwendig. Die Auffrischung des
Schutzmittels bzw. von einem oder mehreren der notwendigen Zusätze, ist
auch automatisiert möglich.
Die Ausgabe von Warnmeldung bei Abweichung von den einzuhaltenden
Grenzwerten der Zusammensetzung des Temperiermediums hilft Folgeschäden
zu vermeiden bzw. erheblich zu reduzieren. Hierzu gehören auch einfachere
Fälle wie z.B. eine Maschinensperrung, deren Entriegelung nur durch Service
möglich ist.
Die Verfügbarkeit der Druckmaschine wird erhöht, da auf die beschriebene
Weise eine betriebssichere Systemüberwachung geschaffen wurde.Manual control work is no longer necessary. The refreshment of the protective agent or one or more of the necessary additives can also be automated.
The output of warning messages in the event of a deviation from the limit values to be observed for the composition of the temperature control medium helps to avoid or significantly reduce consequential damage. This also includes simpler cases such as a machine lock, which can only be unlocked by service.
The availability of the printing press is increased because reliable system monitoring was created in the manner described.
