Abstract
Description
Die Erfindung betrifft einen Formzylinder in einer Offsetdruckmaschine für eine löschbare Direktbebilderung mit einem auf einen Zylinderkörper aufziehbaren Zylindermantel mit hydrophiler bzw. hydrophilierbarer Oberfläche.The invention relates to a forme cylinder in an offset printing machine for an erasable direct imaging with a cylinder jacket with a hydrophilic or hydrophilizable surface that can be pulled onto a cylinder body.
Aus der DE-PS 36 36 129 ist ein gattungsgemäßer Formzylinder bekannt. Diese Art eines Formzylinders weist einen Zylindermantel mit einer druckenden Oberfläche auf, die wärmeisolierende Eigenschaften und einen hydrophilen Charakter besitzt. Dem Formzylinder ist eine Bildinformations-Übertragungseinheit innerhalb der Druckmaschine zugeordnet, über die die Bildinformation in Form von farbannehmenden Flächenelementen auf die Oberfläche der Druckform übertragen wird. Die Bildinformation ist löschbar und der Formzylinder innerhalb der Druckmaschine für eine Bildänderung erneut umschreibbar. Die Feuchtmittelversorgung des Formzylinders wird in der im Offsetdruck üblichen Weise mittels zusätzlicher Feuchtauftragswalzen bzw. Feuchtreiber vorgenommmen.A generic forme cylinder is known from DE-PS 36 36 129. This type of forme cylinder has a cylinder jacket with a printing surface that has heat-insulating properties and a hydrophilic character. An image information transmission unit within the printing press is assigned to the forme cylinder, via which the image information is transferred to the surface of the printing form in the form of ink-accepting surface elements. The image information can be deleted and the form cylinder within the printing press can be rewritten for an image change. The fountain solution is supplied to the forme cylinder in the manner customary in offset printing by means of additional dampening rollers or dampers.
In der US-PS 4 967 663 wird die Anwendung einer ungravierten Dosierwalze aus poröser Keramik vorgeschlagen, bei der die Poren der Keramik die Funktion haben, die Farbflüssigkeit anstatt von Farbnäpfchen aufzunehmen. Die Herstellung eines porösen keramischen Zylinders ist Stand der Technik und auch am Beispiel einer Dosierwalze in der US-PS 4 967 663 im einzelnen beschrieben. Porengröße und Anzahl der Poren wird durch den Zusatz organischer Füllstoffe zur Keramikmasse eingestellt. Die organischen Füllstoffe verbrennen beim Brennen der Keramik, zurück bleibt ein poröser Keramikkörper. Geeignete organische Füllstoffe sind z. B. gemahlene Walnußschalen, Holzpulver, Strohpulver, Fischöl, etc.US Pat. No. 4,967,663 proposes the use of an unengraved dosing roller made of porous ceramic, in which the pores of the ceramic have the function of taking up the ink liquid instead of ink cups. The production of a porous ceramic cylinder is state of the art and also described in detail using the example of a metering roller in US Pat. No. 4,967,663. Pore size and number of pores is set by adding organic fillers to the ceramic mass. The organic fillers burn when the ceramic is fired, leaving a porous ceramic body. Suitable organic fillers are e.g. B. ground walnut shells, wood powder, straw powder, fish oil, etc.
In der DE-PS 38 40 137 ist eine andere Möglichkeit zur Herstellung eines porösen keramischen Skeletts offenbart. Ein Kunststoffschaum, z. B. Polyurethanschaum wird in eine Keramiksuspension getaucht. Beim Brennen der Keramik brennt der Kunststoffschaum heraus, zurück bleibt eine sogenannte Schaumkeramik. Auf diese Weise lassen sich Porendurchmesser zwischen 3 und 100 µm, sowie eine Porosität zwischen 2 und 90 % einstellen.Another possibility for producing a porous ceramic skeleton is disclosed in DE-PS 38 40 137. A plastic foam, e.g. B. Polyurethane foam is immersed in a ceramic suspension. When the ceramic is fired, the plastic foam burns out, leaving a so-called foam ceramic. In this way, pore diameters between 3 and 100 µm and a porosity between 2 and 90% can be set.
Aufgabe der Erfindung ist es, einen porösen Keramikzylinder so auszubilden, daß er als direktbebilderbarer und löschbarer, d. h. wiederverwendbarer Formzylinder einsetzbar ist und zu dem ohne zusätzliche Feuchtauftragswalzen und Feuchtreiber Feuchtmittel zur Oberfläche des Formzylinders zuführbar ist.The object of the invention is to form a porous ceramic cylinder so that it can be directly imaged and erased, ie. H. Reusable forme cylinder can be used and to which dampening solution can be fed to the surface of the forme cylinder without additional dampening rollers and dampers.
Die Lösung dieser Aufgabe gelingt erfindungsgemäß durch einen Formzylinder der eingangs genannten Art, bei welchem der Zylindermantel eine Mehrzahl von Poren aufweist, die im wesentlichen gleicher Größe und gleichmäßig verteilt sind. Die Porengröße und die Anzahl` der Poren ist herstellungsmäßig einstellbar. Die bevorzugte Porösität liegt zwischen 20 und 45 %. Eine vorteilhafte Maßnahme besteht darin, den Durchmesser der Poren in der Weise zu variieren, daß er von der Innenseite des Zylindermantels zur Außenseite desselben hin abnimmt und sich in der Größenordnung von 3 bis 100 µm bewegt. Die Poren des keramischen Zylindermantels kommunizieren miteinander. Durch den Walzenkörper ist Feuchtmittel in der Weise führbar, daß das Feuchtmittel durch die Poren des Zylindermantels an die Oberfläche desselben gelangen kann. Die Feuchtmittelführung durch den Zylinderkern geschieht in an sich bekannter Weise, wie sie bei der Kühlung von Feucht- oder Farbreibern angewendet wird. Zwischen Zylindermantel und Zylinderkern ist ein Feuchtmittelraum vorgesehen, in den Feuchtmittelzuführ- bzw. Ablaufleitungen münden.This object is achieved according to the invention by a forme cylinder of the type mentioned in the introduction, in which the cylinder jacket has a plurality of pores which are essentially of the same size and are uniformly distributed. The pore size and the number of pores can be adjusted in terms of production. The preferred porosity is between 20 and 45%. An advantageous measure consists in varying the diameter of the pores in such a way that it decreases from the inside of the cylinder jacket to the outside of the cylinder jacket and is of the order of 3 to 100 μm. The pores of the ceramic cylinder jacket communicate with each other. Fountain solution can be guided through the roller body in such a way that the fountain solution can reach the surface thereof through the pores of the cylinder jacket. The dampening solution is guided through the cylinder core in a manner known per se, as is used in the cooling of dampening or ink rubbers. A dampening solution chamber is provided between the cylinder jacket and the cylinder core, into which dampening solution supply or discharge lines open.
Geeignete poröse Keramiken für die der Erfindung zugrundeliegende Anwendung sind z. B. Aluminiumoxid (Al₂O₃), Zirkonoxid (ZrO₃), Cordierit (Al-Mg-Silikat), Steatit (Mg-Silikat) oder Siliciumcarbid (SiC).Suitable porous ceramics for the application on which the invention is based are e.g. B. aluminum oxide (Al₂O₃), zirconium oxide (ZrO₃), cordierite (Al-Mg silicate), steatite (Mg silicate) or silicon carbide (SiC).
Materialien aus denen poröse Formzylinder hergestellt werden können sind neben Keramik auch Glas oder Metalle bzw. Metallegierungen. Die pulvermetallurgische Herstellung von Filtern aus Sintermetall, auch in Form von Rohren, ist Stand der Technik, ebenso, wie die gezielte Einstellung unterschiedlicher Porengrößen und Porenverteilungen. Als Werkstoffe kommen insbesondere Bronzen und Crom-Nickel-Legierungen zum Einsatz.In addition to ceramics, materials from which porous forme cylinders can be produced are glass or metals or metal alloys. The powder metallurgical production of filters made of sintered metal, also in the form of tubes, is state of the art, as is the targeted setting of different pore sizes and pore distributions. In particular, bronzes and chromium-nickel alloys are used as materials.

It has a hydrophilic character and has uniformly distributed pores 5 of essentially the same size which are open towards the surface 4.
Fig. 3 zeigt nochmals den Formzylinder 1 im Schnitt. Zwischen dem Zylindermantel 3 und dem Zylinderkern 2 ist im Druckbereich der Oberfläche 4 des Zylindermantels 3 ein an den Stirnseiten durch den Zylinderkörper 2 und im Umfang durch den Zylindermantel 3 begrenzter ein Feuchtmittelraum 6 vorgesehen. Ober Feuchtmittelzuführ- bzw. Abführleitungen durch den Walzenkern 2 ist Feuchtmittel dem Feuchtmittelraum zuführbar und gelangt durch die miteinander kommunizierenden Poren 5 des keramischen Zylindermantels 3 an die Oberfläche 4 desselben.3 again shows the
Der grundsätzliche Aufbau und die Wirkungsweise der Feuchtmittelzufuhr eines Zylinders ist im Zusammenhang mit gekühlten Feucht- bzw. Farbreibern an sich bekannt und bedürfen daher im vorliegenden Zusammenhang keiner eingehenden Erläuterung mehr.The basic structure and the mode of action of the dampening solution supply of a cylinder are known per se in connection with cooled dampening or ink rubbers and therefore do not require any detailed explanation in the present context.
Ein solch endloser aus poröser Keramik hergestellter Zylindermantel 3 kann z. B. über Thermotransfer-, Ink-jet- oder ähnlichen Verfahren direkt mittels einer Bildinformations-Übertragsungseinheit innerhalb der Druckmaschine bildmäßig beschrieben werden. Die Feuchtung der Oberfläche 4 des Zylindermantels 3 erfolgt direkt aus dem Inneren des porösen keramischen Formzylinders 1.

B. via thermal transfer, ink-jet or similar methods directly by means of an image information transmission unit within the printing machine. The surface 4 of the cylinder jacket 3 is dampened directly from the interior of the porous
An den Stellen, an denen auf der Oberfläche 4 des keramischen Zylindermantels 3 bildmäßig aufgebrachtes, farbannehmendes Material sitzt, sind die Poren 5 verstopft, das Feuchtmittel kann nicht bis an die Oberfläche 4 gelangen, so daß in gewünschter Weise farbführende und wasserführende Bereiche auf der Oberfläche 4 des Zylindermantels 3 entstehen. Zur wiederholten Verwendung des Formzylinders 1 muß die Bebilderung entfernt werden. Dies kann z. B. durch Niederdruckplasmabehandlung, Abbrennen mit einer Knallgasflamme oder mechanisches Abschleifen erfolgen. Bei einem weiteren Löschverfahren, daß sich die Porösität des Formzylinders 1 zu Nutze macht, werden vom inneren des porösen Zylinders 1 heißer Wasserdampf oder andere heiße Gase zugeführt, die die Bebilderung von der Druckformoberfläche 4 abheben bzw. absprengen. Vorteilhaft bei diesem Löschverfahren ist, daß der Angriff zur Entfernung der Bebilderung direkt an der kritischen Stelle, d. h. an den Stellen, an denen das bildmäßig aufgebrachte Material sitzt, erfolgt und nicht erst einige Atomlagen bildmäßig aufgebrachtes Material erweicht werden müssen, bevor die entscheidende Schwächung der Adhäsion zwischen oleophilem Material und Druckformoberfläche 4 erfolgen kann.At the points where there is an image-accepting, ink-accepting material on the surface 4 of the ceramic cylinder jacket 3, the pores 5 are clogged, the dampening solution cannot get to the surface 4, so that ink-carrying and water-carrying areas on the surface are desired 4 of the cylinder jacket 3 arise.
