Abstract
Description
Die Erfindung betrifft einen Farbkasten für eine Druckmaschine, vorzugsweise einer Offsetdruckmaschine nach dem Oberbegriff des Hauptanspruches.The invention relates to an ink fountain for a printing press, preferably an offset printing press according to the preamble of the main claim.
Ein Farbkasten dieser Art ist aus dem DE 9 310 680.7 U1 bekannt. Im Farbkasten ist in Nähe des Farbduktors zur Bildung eines Farbeinlaufkeiles eine Trennwand angeordnet. Dem Farbeinlaufkeil wird Farbe zugeführt, die vor bzw. im Farbkasten direkt von gesonderten Temperiereinrichtungen temperiert wird. Nachteilig ist hierbei, daß ein hoher Teileaufwand erforderlich ist.A color box of this type is known from DE 9 310 680.7 U1. A partition is arranged in the ink fountain near the ink duct to form an ink wedge. Color is fed to the ink inlet wedge, which is tempered directly in front of or in the ink fountain by separate temperature control devices. The disadvantage here is that a high expenditure of parts is required.
Aus der DE 3 521 424 C1 ist beispielsweise eine Farbwalze für Druckmaschine bekannt, deren Inneres von Temperiermittel durchflossen ist.From DE 3 521 424 C1, for example, an inking roller for printing press is known, the interior of which is flowed through by temperature control agents.
Ausgehend von diesem Stand der Technik ist es Aufgabe der Erfindung, einen Farbkasten zu schaffen, der mit geringem Aufwand herstellbar ist und mit wenig Aufwand zu reinigen ist.Based on this prior art, it is an object of the invention to provide an ink fountain that can be produced with little effort and can be cleaned with little effort.
Erfindungsgemäß wird dies durch den kennzeichnenden Teil des Hauptanspruches gelöst, Weiterbildungen ergeben sich aus den Unteransprüchen. Die Erfindung beinhaltet weiterhin einen Farbkasten, der reaktionsschnell die Farbe auf eine vorgegebene Temperatur temperiert und gleichzeitig den Reinigungsaufwand bei anstehendem Farbwechsel spürbar reduziert. Durch die Anordnung von Temperiereinrichtungen im Boden des Farbkastens ergeben sich kurze Reaktionszeiten. Dabei ist es vorteilhaft, die Temperiereinrichtungen in den Farbkastenboden als Heiz/Kühlaggregate zu integrieren oder kommunizierende Kanäle anzuordnen, die von einem Temperiermittel durchströmt werden. Der Farbkastenboden selbst ist nach dem Umformprinzip des Strangpressens hergestellt. Dabei wird in bekannter Weise ein Materialblock, beispielsweise mit Hauptbestandteilen aus Stahl oder Aluminium, durch eine Matrize (ein mit entsprechenden Öffnungen versehenes Werkzeug) mittels Preßstempel gedrückt und auf diese Weise wird der Farbkastenboden aus einem Strang erzeugt. Der Farbkastenboden wird durch einen einzigen Umformvorgang in seinem Profil als ein Bauteil erzeugt. Der Strang muß anschließend lediglich auf die entsprechende Länge getrennt werden. Durch die Formänderung im Umformverfahren werden auch die Festigkeitseigenschaften des Materials erhöht. Der Farbkastenboden ist vorzugsweise zusätzlich mit einer oleophoben (farbabstoßenden) Beschichtung versehen. Es wurde gefunden, daß Aluminium bzw. Aluminiumverbindungen als Ausgangsmaterial für den Farbkastenboden besonders geeignet ist. Als zusätzliche Beschichtung auf dem Farbkastenboden eignen sich Eloxalschichten, die nach dem Prinzip der anodischen Oxydation erzeugt werden. In einer Weiterbildung eignen sich auch thermoplastische Beschichtungen, beispielsweise PTFE-Schichten. In einer weiteren Ausbildung ist dem Farbkastenboden eine Platte/Blech zugeordnet, die aus einem oleophoben Werkstoff besteht. Hier eignen sich ebenfalls Aluminium oder Aluminiumverbindungen. Vorzugsweise können die Platten/Bleche ein oder mehrere Druckplatten, beispielsweise gebrauchte Druckplatten, sein. Der stranggespreßte Farbkastenboden besitzt an seiner Farbkastenoberfläche eine sehr glatte Oberfläche (bedingt durch das Strangpreßverfahren und den entsprechenden Werkstoff). Durch Beschichtungen lassen sich sehr gute Reinigungsergebnisse erzielen. Bei Verwendung von Druckplatten läßt sich beim Farbwechsel die restliche Farbe mit der Druckplatte durch Herausnehmen aus dem Farbkasten entfernen. Anschließend müssen lediglich die Seitenteile des Farbkastens manuell gereinigt werden. Die Seitenwände können ebenfalls aus einem Werkstoff mit oleophiler Beschichtung, z.B. Aluminiumwerkstoffen, bestehen. Bei der Verwendung von Druckplatten ist es unerheblich welche Seite der Druckplatte mit der Farbe in Kontakt steht. Entscheidend ist, daß die Druckplatte plan auf dem Farbkastenboden bzw. der Farbkastenoberfläche aufliegt.According to the invention this is solved by the characterizing part of the main claim, further developments result from the subclaims. The invention also includes an ink fountain that quickly temperature-regulates the ink to a predetermined temperature and at the same time noticeably reduces the cleaning effort when the color changes. The arrangement of temperature control devices in the bottom of the ink fountain results in short reaction times. It is advantageous to integrate the temperature control devices into the ink fountain base as heating / cooling units or to arrange communicating channels through which a temperature control agent flows. The ink fountain base itself is manufactured according to the extrusion principle. In a known manner, a block of material, for example with main components made of steel or aluminum, is pressed through a die (a tool provided with corresponding openings) by means of a press ram, and in this way the floor of the ink fountain becomes one strand generated. The ink fountain base is created as a component by a single forming process in its profile. The strand then only has to be cut to the appropriate length. The change in shape in the forming process also increases the strength properties of the material. The ink fountain base is preferably additionally provided with an oleophobic (ink-repellent) coating. It has been found that aluminum or aluminum compounds is particularly suitable as a starting material for the ink fountain base. As an additional coating on the ink fountain base, anodized layers are suitable, which are created according to the principle of anodic oxidation. In a further development, thermoplastic coatings, for example PTFE layers, are also suitable. In a further embodiment, a plate / sheet is assigned to the ink fountain base, which consists of an oleophobic material. Aluminum or aluminum connections are also suitable here. The plates / sheets can preferably be one or more printing plates, for example used printing plates. The extruded ink fountain base has a very smooth surface on its ink fountain surface (due to the extrusion process and the corresponding material). Coatings can achieve very good cleaning results. When using printing plates, the remaining color can be removed with the printing plate by removing it from the ink fountain. Then only the side parts of the ink fountain have to be cleaned manually. The side walls can also consist of a material with an oleophilic coating, for example aluminum materials. When using printing plates, it is irrelevant which side of the printing plate is in contact with the ink. It is crucial that the printing plate lies flat on the ink fountain base or the ink fountain surface.
Der erfindungsgemäße Farbkasten eignet sich mit seiner Temperiereinrichtung besonders für den wasserlosen Offsetdruck (Trockenoffset). Dabei kann dieser Farbkasten allein oder in Kombination mit einer temperierten Farbkastenwalze zum Einsatz in einem Druckwerk kommen.With its temperature control device, the ink fountain according to the invention is particularly suitable for waterless offset printing (dry offset). This ink fountain can be used alone or in combination with a tempered ink fountain roller in a printing unit.

In einem Druckwerk einer Offsetdruckmaschine ist in bekannter Weise ein Farbwerk angeordnet. Das Farbwerk besitzt einen Farbkasten 1, dem eine Farbkastenwalze 2 zugeordnet ist. Der Farbkastenwalze 2 ist eine Farbheberwalze 6 benachbart. Der Farbkasten 1 ist an die Farbkastenwalze 2 anschwenkbar und besitzt eine Vielzahl von eine Dosiereinrichtung 5 bildenden Farbdosierelementen. Die Dosiereinrichtung 5 wirkt zentrisch auf die Farbkastenwalze 2. Auf die Farbsteuerung soll hier nicht weiter eingegangen werden. Der Farbkasten 1 besitzt einen Farbkastenboden 3 sowie Seitenwände 4. Vorzugsweise parallel zur Farbkastenwalze 2 verlaufen im Farbkastenboden 3 Temperiereinrichtungen 7, 8. Die Temperiereinrichtungen 7, 8 sind beispielsweise als Kanäle ausgebildet, die von dem Temperiermedium durchströmt werden oder die Kanäle nehmen Heiz-/Kühlelemente auf. Werden die Temperiereinrichtungen 7, 8 von einem Temperiermedium durchströmt, so ist der der Farbkastenwalze benachbarte Kanal der Temperiereinrichtung 7 als Vorlaufstang für das Medium ausgeführt. Der der Farbkastenwalze 2 abgewandte Kanal der Temperiereinrichtung 8 dient dann als Rücklaufstang. Je nach Temperieranforderung können auch mehrere Kanäle der Temperiereinrichtung 7 der Farbkastenwalze 2 zugewandt und ebenfalls mehrere Kanäle der Temperiereinrichtung 8 der Farbkastenwalze 2 abgewandt angeordnet sein. Die Temperiereinrichtungen 7, 8, sind nahe der Farbkastenoberfläche 9 innerhalb des Farbkastenbodens 3 angeordnet. Der Farbkasten 1 mit Farbkastenboden 3 (einschließlich Farbkastenoberfläche 9) sowie den Kanälen der Temperiereinrichtungen 7, 8 ist einteilig als ein Strangpreßprofil hergestellt. Bei Verwendung eines Farbkastens aus einem stranggepreßten Aluminiumwerkstoff ist die Farbkastenoberfläche 9 bereits oleophob. Bei Verwendung eines Eisenwerkstoffes wird die Farbkastenoberfläche 9 mit einem Aluminiumwerkstoff als anodische Oxydationsschicht 10 beschichtet. Die anodische Oxydationsschicht 10 kann zusätzlich auch auf eine aus einem Aluminiumwerkstoff bestehende Farbkastenoberfläche 9 aufgebracht werden. Der Einsatz einer vorzugsweise gebrauchten Druckplatte, eingelegt auf die Farbkastenoberfläche 9, stellt eine Weiterbildung dar. Ebenso kann die Farbkastenoberfläche 9 eine zusätzliche Beschichtung aus einem termoplastischen Kunststoff, z.B. eine PTFE-Beschichtung (Polytetrafluorethylen) besitzen.An inking unit is arranged in a known manner in a printing unit of an offset printing press. The inking unit has an
Die Wirkungsweise ist wie folgt:
Der Farbkasten 1 ist mit einer Offsetfarbe 12 gefüllt. Die Temperiereinrichtungen 7, 8 werden von einem Temperiermittel durchströmt, welches die Temperatur der Farbe je nach Anforderung erhöht oder reduziert. Der Wärme- oder Kälteeintrag des Temperiermittels wird über den Farbkastenboden 3, die Farbkastenoberfläche 9 in die Farbe 12 übertragen. Bei Verwendung von Heiz-/Kühlelementen erfolgt der Wärme- bzw. Kälteeintrag in die Farbe 12 analog. Nach Beendigung des Druckvorganges bzw. beim Farbwechsel wird die Farbe 12 manuell mittels Spachtel aus dem Farbkasten 1, einschließlich den Farbkastenseitenwänden 4 entfernt. Bei Verwendung einer Platte 11 wird diese einfach vom Farbkastenboden 3 herausgenommen. Noch anhaftende Farbe läßt sich außerhalb des Farbkastens 1 entfernen und die gereinigte Platte 11 kann wieder in den Farbkasten eingelegt werden. Bei Verwendung von oleophobem Material als Farbkastenboden 3, Farbkastenoberfläche 9, Seitenwänden 4 und/oder anodische Oxydationsschichten 10 lassen sich die Reinigungszeiten spürbar reduzieren.The mode of action is as follows:
