Description
Die Erfindung betrifft eine Vorrichtung zum Temperieren von
Beschichtungsmedien nach dem Oberbegriff des Patentanspruchs
1.The invention relates to a device for tempering
Coating media according to the preamble of the
In Auftragswerken für Druckmaschinen beispielsweise in Lakkierwerken ist es bekannt die Viskosität des Beschichtungsmediums über Mittel zum Temperieren zu regulieren. Dies dient dazu, die Verarbeitungsfähigkeit der Beschichtungsmedien für verschiedene Arten von Medien und für verschiedene Verfahrensweisen zum Auftragen regulieren zu können. Damit wird der Arbeitsbereich eines solchen Auftragswerkes erweitert.In contract works for printing presses, for example in painting plants it is known the viscosity of the coating medium regulate by means of tempering. This serves to the processability of the coating media for different types of media and for different procedures to be able to regulate for application. With that the Work area of such a commissioned work expanded.
Aus der US 5520739 A ist beispielsweise eine Vorrichtung zum Beschichten einer Oberfläche in einem Druckprozeß bekannt. Darin wird beschrieben, daß aus einem einzigen Vorratsbehälter eine Beschichtungszusammensetzung für verschiedene Systeme zur Zufuhr der Beschichtungszusammensetzungen zu Druckprozessen bereitgestellt werden kann. Jede Einrichtung zur Zufuhr der Beschichtungszusammensetzung ist als Reaktorbehälter beschrieben, in dem die Temperatur und damit auch die Viskosität der Beschichtungszusammensetzung beeinflusst werden können. Dazu sind in dem Reaktorbehälter ein Wärmetauscher und eine Temperatursensorik sowie ein Viskosimeter zur Bestimmung der Viskosität der Beschichtungszusammensetzung vorgesehen.From US 5520739 A, for example, a device for Coating a surface in a printing process is known. It describes that from a single reservoir a coating composition for various systems for feeding the coating compositions to printing processes can be provided. Any facility for Feed of the coating composition is as a reactor vessel described in which the temperature and thus the Influences viscosity of the coating composition can be. For this purpose there is a heat exchanger in the reactor vessel and a temperature sensor system and a viscometer Determination of the viscosity of the coating composition intended.
Die beschriebene Vorrichtung hat den Nachteil, daß die Beschichtungszusammensetzung nur im Vorgriff zum eigentlichen Druckprozeß bzw. Beschichtungsprozeß beeinflusst werden kann. Auf dem Weg zwischen dem Reaktorbehälter und dem Druckprozeß können sich die physikalischen Bedingungen der Beschichtungszusammensetzung wieder ändern. The described device has the disadvantage that the coating composition only in anticipation of the actual one Printing process or coating process can be influenced. On the way between the reactor vessel and the printing process can change the physical conditions of the coating composition change again.
Ein weiterer Nachteil der beschriebenen Vorrichtung ist, daß nicht alle Verfahrensabläufe durch die Verfahrensabläufe der Temperierung erfasst werden. Es ist beispielsweise notwendig Abläufe für das Spülen bzw. Reinigen des Auftragwerkes und der darin enthaltenen die Beschichtungszusammensetzung transportierenden Elemente vorzusehen, um eine dauerhafte Verunreinigung durch aushärten der Beschichtungszusammensetzung zu vermeiden. Hierbei ist es vorteilhaft, die Temperatur des Reinigungsprozesses zu beeinflussen. Dies ist mit der beschriebenen Vorrichtung nicht möglich.Another disadvantage of the device described is that not all procedures by the procedures of Temperature control can be recorded. For example, it is necessary Processes for rinsing or cleaning the applicator and of the coating composition contained therein Elements to provide for permanent pollution by curing the coating composition avoid. It is advantageous to adjust the temperature of the To influence the cleaning process. This is with the one described Device not possible.
Aufgabe der Erfindung ist es daher die Temperierung eines Beschichtungsmediums nahe am Druckprozeß zu beeinflussen und andererseits Sorge zu tragen, daß Reinigungsprozesse ebenfalls durch Temperiermechanismen unterstützt werden können.The object of the invention is therefore the tempering of a To influence coating medium close to the printing process and on the other hand, to ensure that cleaning processes too can be supported by temperature control mechanisms.
Die Lösung dieser Aufgabe gestaltet sich nach dem Kennzeichen
der Anspruchs 1. Hierbei kommt vorteilhaft zur Geltung, daß
dem Auftragwerk ein das Beschichtungsmedium aufnehmender
temperierbarer Behälter zugeordnet ist. Diesem Behälter
können in besonders vorteilhafter Weise sowohl Beschichtungsmedium
als auch ein der Reinigung dienendes Spühlmedium
zugeführt werden. Durch die Zuführung des Spülmediums in den
Zwischenbehälter ist dieses ebenfalls auf eine für den Reinigungsprozeß
geeignete Temperatur einstellbar. Hierbei wird
der Zwischenbehälter in geeigneter Weise von den Behältern
zur Zufuhr des Beschichtungsmediums getrennt. Durch die
aufgezeigte Anordnung ist jederzeit sichergestellt, daß alle
mit dem Beschichtungsmedium in Berührung kommenden Elemente
angemessen gereinigt werden können.
Die Wirkung der verbesserten Reinigung ist auch in weiterer
vorteilhafter Anordnung mittels temperierter Elemente zur
Führung und Dosierung des Beschichtungsmediums erzielbar. The solution to this problem is designed according to the characterizing part of
The effect of the improved cleaning can also be achieved in a further advantageous arrangement by means of temperature-controlled elements for guiding and metering the coating medium.
Die Erfindung wird im Folgenden an Hand von zeichnerischen Darstellungen näher erläutert. Darin zeigen:
- Fig. 1
- ein Auftragswerk und

- a supply device with a temperature-controlled intermediate container in normal washing mode
In Figur 1 ist ein Auftragswerk beschrieben. Das Auftragswerk
beinhaltet einen Druckzylinder 1 zur Führung eines zu beschichtenden
Bogens, einen Formzylinder 2 zur Übertragung
einer Schicht des Beschichtungsmediums auf den zu bedruckenden
Bogen und ein Dosierwerk zu Erzeugung der Beschichtung.
Das Dosierwerk besteht im gezeigt Fall aus einer Auftragwalze,
die als Rasterwalze 3 ausgebildet ist und zum Transport
des Beschichtungsmediums gleichmäßig mit Näpfchen versehen
ist. An dieser Rasterwalze 3 ist ein Kammerrakel 4 angestellt,
dessen beide Rakel gemeinsam mit dem Körper des
Kammerrakels 4 einen Raum zum Zuführen des Beschichtungsmediums
bilden. Das Kammerrakel 4 wird mit seinen beiden Rakeln
gegen die Rasterwalze 3 angestellt und überträgt unter Zufuhr
des Beschichtungsmediums mittels einer Pumpe das Beschichtungsmedium
in die Vertiefungen der Rasterwalze 3. Das Beschichtungsmedium
wird beim Abwälzen der Rasterwalze 3 auf
der Oberfläche des Formzylinders 2 an eine dort befestigte
Druckform abgegeben. Die Druckform kann eine das gesamte
Sujet eines Druckbogens überstreichende einheitliche Fläche
sein, sie kann aber auch nur für Teile des Druckbogens vorgesehen
sein. A commissioned work is described in FIG. The commissioned work
includes a
Dem Kammerrakel 4 wird das Beschichtungsmedium mittels Förderleitungen
A zugeführt und mittels Förderleitungen B von
dort wieder abgeführt. Die Förderleitungen A und B sind mit
dem Mediumfördersystem, das Förder- und Saugpumpen beinhaltet,
verbunden.The coating medium is applied to the
In den Figuren 2 a, 2 b und 2 c ist ein System zur Temperierung
im Zusammenhang mit einem Zwischenbehälter 5 gezeigt.
Der Zwischenbehälter 5 ist derart angeordnet, daß er einerseits
mit Beschichtungsmedium aus einem Vorratsbehälter 6
versorgt werden kann. Mit dem Zwischenbehälter 5 sind auch
die Förderleitungen A und B verbunden. Andererseits kann der
Zwischenbehälter 5 auch mit einem ein Schmutzmedium beinhaltenden
Behälter 7 verbunden werden. Dadurch wird im Betrieb
bei Beschichtung das Beschichtungsmedium durch den Zwischenbehälter
5 geführt und dort auf eine bestimmte Temperatur
eingestellt. Dies kann durch Kühlung oder Heizung erfolgen.
Dazu sind Sensoren vorzusehen, die die Temperatur des Beschichtungsmediums
erfassen. Die Sensoren können an dem
Zwischenbehälter 5 oder an der Beschichtungseinrichtung
selbst angeordnet sein. Durch die Temperierung wird der
Verarbeitungsprozeß sichergestellt.In Figures 2a, 2b and 2c is a system for temperature control
shown in connection with an
Für die entsprechenden Verbindungen sind geeignete Leitungsund Ventilsysteme vorgesehen.Suitable line and Valve systems provided.
Beim Reinigen des gesamten Lack- bzw. Beschichtungsmediumsystemes
kann nun wiederum das Spülmittel durch den Zwischenbehälter
5 geführt werden. Je nach Art des zu verarbeitenden
Beschichtungsmediums kann nun eine unterschiedliche Temperatur
des Spülmediums eingestellt werden. Dadurch wird sowohl
die Zufuhr des Beschichtungsmediums in Form einer Nachdosierpumpe
8 als auch der gesamte Beschichtungsmedienkreislauf in
optimaler Weise und in kürzest möglicher Zeit gereinigt. Die
Nachdosierpumpe 8 kann sogar zum Umpumpen des Spülmittels
beim Reinigen dienen.When cleaning the entire paint or coating medium system
can now again the detergent through the
Auf die beschriebene Weise wird also der Zwischenbehälter 5
als Temperierbehälter in den Beschichtungsmedien- und den
Spülkreislauf eingebunden. Der Zwischenbehälter 5 ist ein
eigenständiges austauschbares Element und kann abhängig von
seiner Funktion zum Heizen oder Kühlen eingesetzt werden. Der
Vorteil eines Zwischenbehälters 5 besteht unter anderem
darin, daß er nicht als Durchlaufwärmetauscher fungiert.
Durchlaufwärmetauscher sind üblicherweise wegen der kurzen
Verweildauer des zu temperierenden Mediums mit großem Energieaufwand
zu betreiben und bieten nur mangelhafte bzw.
extrem erschwerte Reinigungsmöglichkeiten.The
Bei einer entsprechenden Dimensionierung kann der Zwischenbehälter
5 als Vorratsbehälter für einen Druckauftrag verwendet
werden. Dann wird die Verbindung zum Vorratsbehälter 6 nach
Füllung des Zwischenbehälters 5 unterbrochen und die Nachdosierpumpe
8 pumpt das Beschichtungsmedium lediglich im Umwälzbetrieb
zur Aufrechterhaltung der Konsistenz um. Dieses
Verfahren kann auch zum Beenden eines Druckauftrages verwendet
werden. Dann wird die Zufuhr von Beschichtungsmedium vom
Vorratsbehälter 6 zum Zwischenbehälter 5 rechtzeitig unterbrochen,
sodaß die verbleibende Menge an Beschichtungsmedium
im Zwischenbehälter 5 noch ausreicht, um den Druckauftrag
noch sicher zu beenden. Damit wird Aufwand für das Rückfördern
von Beschichtungsmedium in den Vorratsbehälter 6 und
Zeit beim Reinigen des System eingespart.With an appropriate dimensioning, the intermediate container can
5 used as a storage container for a print job
become. Then the connection to the
Zur Sicherstellung einer gleichmäßigen Verarbeitung unterschiedlichster
Beschichtungsmedien können an dem Auftragswerk
weiterhin unterschiedliche Temperiereinrichtungen vorgesehen.
Im Bereich des Kammerrakels 4 kann im Rakelkörper oder an
diesen angesetzt eine Wärmetauschereinrichtung beliebiger
bekannter Art eingesetzt werden. Damit läßt sich der Rakelkörper
inklusive der mit diesem verbundenen Rakel auf eine
bestimmte Temperatur einstellen, die wiederum auf das in dem
Kammerrakel 4 vorhandene Beschichtungsmedium übertragen wird.
Weiterhin kann die Rasterwalze 3 mit einer aus Farbwerken von
Rotationsdruckmaschinen bekannten Temperiereinrichtung versehen
sein. Dazu kann die Rasterwalze 3 mit einer Reihe von
Strömungskanälen durchzogen sein, die wechselseitig mit einer
Temperierflüssigkeit durchströmt werden.
Eine weiter Möglichkeit zur Temperierung besteht darin den
Formzylinder 2 mit einer wie von der Rasterwalze 3 her bekannten
Temperiereinrichtung zu versehen.
Alternativ kann zur Beschichtung mittels eines Kammerrakels
und einer Rasterwalze auch ein Walzenbeschichtungswerk vorgesehen
sein. Durch Anordnung von Temperiereinrichtungen an
beiden Walzen gegebenenfalls auch nur an einer der beiden
Walzen läßt sich die Temperatur des zu übertragenden Beschichtungsmediums
genauso einstellen.
Ausgeweitet werden kann das beschriebene System dadurch, daß
in Walzenlackierwerken bzw. Walzenbeschichtungseinheiten auch
eine eventuell vorzusehende Lackwanne vergleichbar mit dem
Kammerrakel oder der Lackzulauf an einem sogenannten Quetschwalzensystem,
zum Beispiel ein in einen Lackvorrat zwischen
den das Quetschwalzensystem bildenen beiden Walzen tauchendes
Lackschwert, temperierbar ist.To ensure uniform processing of a wide variety of coating media, different temperature control devices can also be provided on the application unit. In the area of the chambered
Another possibility for temperature control is to provide the
Alternatively, a roller coating unit can also be provided for coating by means of a chamber doctor blade and an anilox roller. The temperature of the coating medium to be transferred can be set in exactly the same way by arranging temperature control devices on both rollers, possibly also only on one of the two rollers.
The system described can be expanded by the fact that in roller coating units or roller coating units, a coating pan that may be provided is comparable to the chamber doctor blade or the coating supply on a so-called squeeze roller system, for example a lacquer sword immersed in a lacquer supply between the two rollers forming the squeeze roller system.
Weiterhin können Reinigungsflüssigkeiten, die auf die mit dem Beschichtungsmedium in Verbindung kommenden Oberflächen aufzutragen sind, ebenfalls temperiert, vorzugsweise erwärmt werden. Furthermore, cleaning fluids that are on the with Coating medium in contact with surfaces are to be applied, also tempered, preferably heated become.
