Die Erfindung betrifft einen Farbkasten für eine Offsetdruckmaschine nach dem Oberbegriff des Hauptanspruches.The invention relates to an ink fountain for an offset printing machine 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. The color box is in A partition is arranged near the ink duct to form an ink inlet wedge. Color is supplied to the ink inlet wedge, which is directly in front of or in the ink fountain Temperature control devices is tempered. The disadvantage here is that a high amount 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 a printing press is known, whose interior is flowed through by temperature control agents.
Gemäß US-A 4,492,486 ist ein Farbkasten für den Siebdruck bekannt, der aus einem einteiligen Strangpreßprofil gebildet ist. Der Farbkasten soll von der verwendeten Farbflüssigkeit gut reinigbar sein.According to US-A 4,492,486 a color box for screen printing is known, which consists of a one-piece Extruded profile is formed. The ink fountain should be of the paint liquid used be easy to clean.
Nach US-A 5,036,762 ist ein temperierbarer Farbkasten bekannt, der einen mehrteiligen Aufbau aufweist. Der eigentliche Farbkasten ist in einem Isoliergehäuse aufgenommen. Zwischen dem Farbkasten und dem Isoliergehäuse sind Temperiereinrichtungen angeordnet.According to US-A 5,036,762, a temperature-controllable ink fountain is known, which has a multi-part Has structure. The actual ink fountain is housed in an insulating housing. There are temperature control devices between the ink fountain and the insulating housing arranged.
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.Starting from this prior art, it is an object of the invention to provide an ink fountain to create that can be produced with little effort and clean with little effort is.
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 Oxidation 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 Werkstoffbesteht. 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 oleophober 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 training results from the subclaims. The invention further includes a color box that quickly reacts the color to a given temperature tempered and at the same time the cleaning effort noticeable when the color changes reduced. By arranging temperature control devices in the bottom of the ink fountain there are short reaction times. It is advantageous to use the temperature control devices in to integrate the ink fountain floor as heating / cooling units or communicating channels to arrange, which are flowed through by a temperature control. The ink fountain floor itself is manufactured using the extrusion principle. It is known in A block of material, for example with main components made of steel or aluminum, through a die (a tool provided with corresponding openings) by means of Press stamp pressed and in this way the ink fountain base is made from one strand generated. The ink fountain base is made by a single forming process in its profile generated as a component. The strand then only needs to be of the appropriate length be separated. The change in shape in the forming process also increases the strength properties of the material increased. The ink fountain base is preferably additional provided with an oleophobic (color-repellent) coating. It was found, that aluminum or aluminum compounds as the starting material for the ink fountain floor is particularly suitable. Suitable as an additional coating on the ink fountain base there are anodized layers that are produced on the principle of anodic oxidation. In Thermoplastic coatings are also suitable for further development, for example PTFE layers. In a further training, the plate bottom is a plate / sheet assigned, which consists of an oleophobic material. Aluminum is also suitable here or aluminum connections. The plates / sheets can preferably be one or several printing plates, for example used printing plates. The extruded Ink fountain floor has a very smooth surface on its ink fountain surface (conditionally through the extrusion process and the corresponding material). Through coatings very good cleaning results can be achieved. When using pressure plates the remaining color can be removed with the printing plate when changing the color remove from the ink fountain. Then only the side parts of the Ink box can be cleaned manually. The side walls can also be made of one material with oleophobic coating, e.g. Aluminum materials. When using From printing plates it is irrelevant which side of the printing plate with the color is in contact. It is crucial that the printing plate is level on the ink fountain floor or the ink fountain surface.
