Abstract

Temperature control of the coating medium is performed to influence the processability of coating media in an applicator system. In order to operate without losing efficiency, devices acting directly from the inside or the outside for heat supply or dissipation are connected to the elements guiding the coating medium. The temperature of the coating medium is influenced by measuring the temperature within the coating medium and, if necessary, at the elements guiding the coating medium.

Description

Die Erfindung betrifft eine Vorrichtung zum Temperieren von Beschichtungsmedien nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a device for controlling the temperature of Coating media according to the preamble of the claim 1.

[Stand der Technik][State of the art]

In Auftragswerken für Druckmaschinen beispielsweise in Lackierwerken 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 commissioned works for printing presses, for example, in coating plants it is known the viscosity of the coating medium to regulate means of tempering. This serves in addition, the processability of the coating media for different types of media and for different procedures to regulate for application. This will be the Work area of such 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 known. It describes that from a single reservoir a coating composition for various systems for supplying the coating compositions to printing processes can be provided. Every facility for Feed of the coating composition is as a reactor vessel described in which the temperature and thus the Viscosity of the coating composition influenced can be. These are in the reactor vessel, a heat exchanger and a temperature sensor and a viscometer for 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 device described has the disadvantage that the coating composition only in anticipation of the actual 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 through the procedures of the Temperature control are recorded. It is necessary, for example Procedures for rinsing or cleaning the applicator and the coating-transporting composition contained therein Provide elements to a permanent pollution by curing the coating composition avoid. Here it is advantageous the temperature of To influence cleaning process. This is with the described Device not possible.

[Aufgabe der Erfindung]OBJECT OF THE INVENTION

Aufgabe der Erfindung ist es daher die Temperierung einer Beschichtungsmedium 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 temperature of a To influence coating medium close to the printing process and On the other hand, take care that cleaning processes also can be supported by tempering mechanisms.

Die Lösung dieser Aufgabe gestaltet sich nach dem Kennzeichen der Anspruchs 1. Hierbei kommt vorteilhaft zur Geltung, daß die Temperierung der Beschichtungszusammensetzung nicht mehr in einem vorgelagerten Behälter, sondern direkt am Ort der Verarbeitung erfolgt. Geeignete Stellen zur Temperierung sind ein Kammerrakel, eine mit dem Kammerrakel in Verbindung stehende Rasterwalze, eine gegebenenfalls mit dem der Rasterwalze oder mit einer vergleichbaren Auftragwalze verbundene Dosierwalze. Vorteilhaft ist es auch, wenn der die Lackschicht bzw. das Beschichtungsmedium übertragende Formzylinder als Vorrichtung zum Temperieren ausgebildet ist. In geeigneter Form kann innerhalb der jeweiligen Walze bzw. des Kammerrakels ein Wärmetauscher vorgesehen sein. In weiterhin geeigneter Form wird die Temperatur am jeweiligen des Beschichtungsmedium übertragenen Element erfasst.The solution of this task is based on the indicator Claim 1. Here is advantageous advantage that the temperature of the coating composition is no longer in an upstream container, but directly at the place of Processing takes place. Suitable locations for temperature control are a chambered scraper, one in connection with the chambered doctor blade standing anilox roller, one optionally with the anilox roller or associated with a comparable applicator roll Metering. It is also advantageous if the paint layer or the coating medium transmitting form cylinder is designed as a device for tempering. In suitable shape can within the respective roller or the Chamber doctor provided a heat exchanger. In continue proper shape, the temperature at each of the coating medium detected transmitted element.

[Beispiele][Examples]

Die Erfindung wird im Folgenden an Hand von zeichnerischen Darstellungen näher erläutert. Darin zeigen:

Fig. 1
ein Auftragswerk mit Temperiervorrichtungen
The invention will be explained in more detail below with reference to drawings. Show:
Fig. 1
a commissioned work with tempering devices

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 ist ein Kammerrakel 4 angestellt, dessen beide Rakel gemeinsam mit dem Körper des Kammerrakels 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.FIG. 1 describes a commissioned work. The commissioned work includes a printing cylinder 1 for guiding a to be coated Bogens, a form cylinder 2 for transmission a layer of the coating medium on the to be printed Sheet and a dosing to produce the coating. The metering unit consists in the case shown of a mandrel, which is designed as an anilox roller 3 and for transport the coating medium evenly provided with wells is. At this anilox roller a chamber doctor blade 4 is employed, its two squeegees together with the body of the chambered doctor blade form a space for supplying the coating medium. The Chamber doctor 4 is with its two doctor blades against the anilox roller 3 and transfers with supply of the coating medium by means of a pump, the coating medium in the indentations of the anilox roller 3. The coating medium is when rolling the anilox roller 3 on the surface of the Form cylinder 2 delivered to a printing plate attached there. The printing form can be the entire subject of a printed sheet but it can be too be provided only for parts of the sheet.

Zur Sicherstellung einer gleichmäßigen Verarbeitung unterschiedlichster Beschichtungsmedien sind an dem Auftragswerk unterschiedliche Temperiereinrichtungen vorgesehen.To ensure uniform processing of a wide variety of Coating media are on the commissioned work provided different tempering.

Im Bereich des Kammerrakels 4 kann im Rakelkörper oder an diesen angesetzt eine Wärmetauschereinrichtung A 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. Das Beschichtungsmedium nimmt dabei kontinuierlich die vorgewählte Temperatur ein. Dazu kann im Kammerrakel 4 ein Temperatursensor vorgesehen sein, der kontinuierlich die Temperatur des Kammerrakels 4 erfasst. Weiterhin kann im Kammerrakel 4 ein Temperatursensor vorgesehen sein, der kontinuierlich die Temperatur des Beschichtungsmediums erfasst. Bei einer Anordnung beider Sensoren ist ein permanenter Abgleich möglich. Eine Regelung stellt sicher, daß gegebenenfalls eine ausreichend große Temperaturdifferenz zwischen dem Rakelkörper und dem zugeförderten Beschichtungsmedium besteht, damit das Beschichtungsmedium bei der Verarbeitung die gewünschte auf Viskosität und Übertragungseigenschaften, sowie gegebenenfalls auch Trocknungseigenschaften abgestimmte Temperatur annimmt.In the area of the chamber doctor blade 4 can in Rakelkörper or on this set a heat exchanger device A arbitrary known type can be used. This can be the squeegee body including the squeegee connected to it set certain temperature, which in turn to that in the Chamber doctor 4 existing coating medium is transferred. The coating medium continuously takes the preselected Temperature. For this purpose, in the chambered doctor blade 4, a temperature sensor be provided, which continuously reduces the temperature of the chamber doctor blade 4 detected. Furthermore, in the chambered doctor blade 4, a temperature sensor may be provided which is continuous detects the temperature of the coating medium. At a Arrangement of both sensors is a permanent adjustment possible. A rule ensures that, if necessary, a sufficiently large temperature difference between the doctor body and the conveyed coating medium, so that the coating medium during processing the desired on viscosity and transmission properties, and optionally also drying properties matched temperature accepts.

Weiterhin kann die Rasterwalze 3 mit einer aus Farbwerken von Rotationsdruckmaschinen bekannten Temperiereinrichtung B versehen sein. Dazu kann die Rasterwalze 3 mit einer Reihe von Strömungskanälen durchzogen sein, die wechselseitig mit einer Temperierflüssigkeit durchströmt werden. Die Strömungskanäle sind dabei so angeordnet, das die Temperierflüssigkeit in einem Kanal in einer Richtung der Rasterwalze 3 strömt und im benachbarten Kanal in der Gegenrichtung zurückströmt. Dadurch kann die Temperierflüssigkeit von einer Seite der Rasterwalze 3 zugeführt und wieder abgeführt werden.Furthermore, the anilox roller 3 with one of inking of Rotary printing machines known tempering B be provided. For this purpose, the anilox roller 3 with a number be traversed by flow channels, the mutually with a tempering liquid to flow through. The flow channels are arranged so that the tempering flows in a channel in one direction of the anilox roller 3 and flows back in the opposite channel in the opposite channel. As a result, the bath liquid from one side of the Anilox roller 3 fed and discharged again.

Eine weiter Möglichkeit zur Temperierung besteht darin den Formzylinder 2 mit einer wie von der Rasterwalze 3 her bekannten Temperiereinrichtung C zu versehen. Dazu werden auch in dem Formzylinder 2 Strömungskanäle vorgesehen, die mit einem Temperiermedium durchströmbar sind.Another option for temperature control is the Form cylinder 2 with a known from the anilox roller 3 forth Tempering device C to provide. To do this too in the forme cylinder 2 flow channels provided with a temperature control medium can be flowed through.

Alternativ kann zur Beschichtung mittels eines Kammerrakels und einer Rasterwalze auch ein Walzenbeschichtungswerk vorgesehen sein. Dieses Walzen Beschichtungswerk besteht beispielsweise aus zwei Walzen von denen eine die Auftragwalze entsprechend der Rasterwalze 3 und die Zweite eine Dosierwalze an der Stelle des Kammerrakels 4 ist. Die Zuführung des Beschichtungsmediums erfolgt in einen Spalt zwischen beiden Walzen. 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.Alternatively, for coating by means of a chamber doctor blade and an anilox roller also provided a roller coating plant be. This roll coating unit is, for example from two rolls of which one the applicator roll according to the anilox roller 3 and the second a metering roller at the location of the chambered doctor blade 4 is. The feeder of the Coating medium takes place in a gap between the two Rollers. By arranging tempering devices on both Rolls possibly only on one of the two rollers can be the temperature of the coating medium to be transferred set the same way.

Mit den in diesem Zusammenhang beschriebenen Temperiereinrichtungen kann auf einer sogenannte externe Temperierung des Beschichtungsmediums im Transportsystem des Beschichtungsmediums verzichtet werden. Die Lackversorgungsgeräte können konventioneller Art sein. Mit der vorgesehenen Anordnung von Temperiereinrichtungen ist es ebenfalls selbstverständlich möglich eine Kombination mit externen Temperiergeräten vorzunehmen. Weiterhin können Reinigungsflüssigkeiten, die auf die mit dem Beschichtungsmedium in Verbindung kommenden Oberflächen aufzutragen sind, ebenfalls temperiert, vorzugsweise erwärmt werden.With the tempering described in this context can be due to a so-called external tempering of the Coating medium in the transport system of the coating medium be waived. The paint supply devices can be conventional. With the proposed arrangement of Temperature control equipment is also a matter of course possible to combine with external temperature control units. Furthermore, cleaning fluids that on the surfaces in contact with the coating medium be applied, also tempered, preferably to be heated.

Die Temperierung kann auch von außen durch Strahler oder Zufuhr eines gasförmigen Temperiermediums erfolgen. Dann kann die Temperierung auch den bereits dosierten dünnen Schichten des Beschichtungsmediums besonders effektiv zugeordnet werden.The tempering can also be done externally by spotlights or Supply of a gaseous tempering take place. Then can the temperature also the already metered thin layers the coating medium are assigned particularly effective.

Ein besonderen Vorteil der Temperierung der Kammerrakel 4 ist das sich die Rakelmesser durch schwankende Temperatur nicht verspannen können. Eine Verspannung bzw. Biegung der Rakel führt zu unterschiedlichen Dosierungen über die Rakelbreite, die damit vermieden wird.A particular advantage of the temperature of the chambered doctor blade 4 is The doctor blades are not affected by fluctuating temperature can tense. A tension or bending of the squeegee leads to different dosages over the doctor blade width, which is avoided.

In besonderer Weise sind mit der genannten Vorrichtung Verfahrenskombinationen zur Anwendung von verschiedenen Auftragsprozessen der der Lackiertechnik in Bogenoffsetdruckmaschinen oder reinen Beschichtungsmaschinen mit mehreren Auftragswerken möglich. Hierbei kann vorgesehen sein Dispersionslack auf Dispersionslack zu beschichten. Es kann vorgesehen sein Dispersionslack mit Goldlack zu kombinieren. Es kann vorgesehen sein einen Dispersionslack als Grundbeschichtung mit einem UV-Lack zu kombinieren. Schließlich kann vorgesehen sein zwei Schichten von UV-Lack aufzutragen. Im Fall von Dispersionslack dient die Temperierung zur Stabilisierung der Lackeigenschaften. Im Fall von UV-Lack dient die Temperierung, insbesondere durch Heizung, zur Verbesserung der Verlaufeigenschaften, d.h. der Verteilung des Lackes auf eine Oberfläche. Im Zusammenhang mit einem beispielsweise wässrigen Metallpigmentlack oder einer Metallpigmentdruckfarbe kann Kühlung vorgesehen werden, da dieser Lack bzw. diese Druckfarbe in bestimmten Temperaturbereichen eine optimale Konsistenz aufweist.In a special way are with the said device process combinations for the application of different order processes the painting technique in sheet-fed offset printing presses or pure coating machines with several Commissioned works possible. In this case, it is possible to provide a dispersion varnish to coat on dispersion varnish. It can be provided to combine its dispersion varnish with gold varnish. It may be provided a dispersion varnish as a primer coating to combine with a UV varnish. Finally, can be provided to apply two layers of UV varnish. in the In the case of dispersion varnish, the temperature serves for stabilization the paint properties. In the case of UV varnish serves the Temperature control, in particular by heating, to improve the running properties, i. the distribution of the paint on a surface. In connection with an example aqueous metal pigment paint or a metal pigment printing ink cooling can be provided, since this paint or this Printing ink in certain temperature ranges optimal Has consistency.

Ausgeweitet werden kann das beschriebene System dadurch, daß in Walzenlackierwerken bzw. Walzenbeschichtungseinheiten auch eine eventuell vorzusehende Lackwanne vergleichbar mit dem Kammerrakel 4 oder der Lackzulauf an einem sogenannten Quetschwalzensystem, zum Beispiel ein in einen Lackvorrat zwischen den das Quetschwalzensystem bildenen beiden Walzen tauchendes Lackschwert, temperierbar ist. The described system can be extended by the fact that in roll coating or roller coating units also a possibly envisaged paint tray comparable to the Chamber doctor blade 4 or the paint feed to a so-called Crimping system, for example, in a paint stock between the two rolls forming the nip roll system Diving paint sword, can be tempered.
