Description

Die vorliegende Erfindung betrifft ein Zylindermantelprofil nach dem Oberbegriff des Patentanspruches 1.The present invention relates to a cylinder jacket profile according to the preamble of Claim 1.

Ein derartiges Zylindermantelprofil ist bekannt aus der DE 42 07 119 C2, wobei ein Gegendruck- oder Bogenführungszylinder eine Oberflächenbeschichtung aufweist, die parallel zur Druckzylinderachse geschliffen ist. Das Zylindermantelprofil ist aus senkrecht zur Zylindermantelfläche angeordneten zylindrischen Erhebungen gebildet. Deren Zylinderlänge beträgt 20 bis 200 µm und deren Rasterfeinheit 400 bis 10000 Rasterpunkte/cm2. Dabei besitzt der Druckzylinder eine Oberflächenbeschichtung aus Chrom, in die das Zylindermantelprofil eingeätzt ist. Dieses besteht aus einzelnen statistisch gleichmäßig verteilten Erhebungen. Nachteilig dabei sind die hohe Oberflächenenergie von Chrom mit 78 mN/m wegen der damit verbundenen Verschmutzungsprobleme bzw. dem Verschmieren der frisch bedruckten Oberfläche sowie das aufwendige Herstellungsverfahren.Such a cylinder jacket profile is known from DE 42 07 119 C2, wherein a Counter-pressure or sheet guide cylinder has a surface coating that is ground parallel to the impression cylinder axis. The cylinder jacket profile is vertical cylindrical elevations arranged to the cylindrical surface. their Cylinder length is 20 to 200 µm and their screen fineness is 400 to 10,000 Dots / cm2. The printing cylinder has a surface coating Chrome into which the cylinder jacket profile is etched. This consists of individual statistical ones evenly distributed surveys. The disadvantage is the high Surface energy of chrome with 78 mN / m because of the associated Soiling problems or smearing of the freshly printed surface as well the complex manufacturing process.

Weiterhin ist es allgemein bei Druckzylindern bekannt, zur besseren Reinigbarkeit eine Antihaftbeschichtung beispielsweise aus Teflon oder Silikon mit einer typischen Schichtdicke von etwa 20 µm aufzubringen. Nachteilig dabei ist insbesondere die durch diese Schicht bedingte starke Veränderung der Oberflächenstruktur des Druckzylinders und die damit verbundene zunehmende Verschlechterung des Druckergebnisses. Weiterhin ist die Verschleißfestigkeit sowie die chemische Beständigkeit gegenüber den Reinigungs- und Druckchemikalien dieser Antihaftbeschichtungen gering. Auch können insbesondere derart beschichtete Druckzylinder beim Druckvorgang häufig den Bogen nur unzureichend halten.Furthermore, it is generally known in the case of printing cylinders, for better cleanability Non-stick coating, for example made of Teflon or silicone with a typical layer thickness of about 20 µm. The disadvantage of this is particularly that Layer-induced strong changes in the surface structure of the printing cylinder and the associated increasing deterioration in the printing result. Furthermore, the Wear resistance as well as the chemical resistance to the cleaning and Printing chemicals of these non-stick coatings are low. In particular, such coated printing cylinders often insufficiently the sheet during the printing process hold.

Allgemein bekannt sind verschiedene Technologien für Antihaftbeschichtungen mit sehr geringer Oberflächenenergie. Beispielsweise werden amorphe, diamantähnliche Kohlenstoffschichten mit CVD- oder PVD-Verfahren bei typischen Schichtdicken von 1 bis 10 µm abgeschieden. Dabei können verschleißbeständige Antihaft-Schichten mit geringer Oberflächenenergie bzw. ―spannung (typ. 20 ― 40 mN/m) zur Oberflächenveredlung von beispielsweise Werkzeugen realisiert werden.Various technologies for non-stick coatings with are very well known low surface energy. For example, amorphous, diamond-like Carbon layers with CVD or PVD processes with typical layer thicknesses of 1 deposited up to 10 µm. Wear-resistant non-stick layers can be used low surface energy or tension (typ. 20 - 40 mN / m) for Surface finishing of tools, for example, can be realized.

Die Colloid-Technologie ist eine neue Technologie zur Antihaft-Beschichtung von Oberflächen bei Schichtdicken von 100 nm bis 10 µm. Diese Technologie nutzt die Komplexbildung eines Polyelektrolyten mit Fluortensiden. Die nach außen exponierte Tensidschicht, die selbst etwa nur bis zu 1 nm stark ist, zeichnet sich durch extreme Glattheit und äußerst niedrige Oberflächenspannung aus (11 ― 16 mN/m).Colloid technology is a new technology for non-stick coating Surfaces with layer thicknesses from 100 nm to 10 µm. This technology uses the Complex formation of a polyelectrolyte with fluorosurfactants. The exposed to the outside Surfactant layer, which itself is only up to 1 nm thick, is characterized by extreme Smoothness and extremely low surface tension from (11 - 16 mN / m).

Mit anorganisch-organischen Hybridpolymeren können über den Einbau von funktionellen Gruppen beispielsweise von perfluorierten Silanverbindungen in das Silicatgrundgerüst Schichten mit antiadhäsiven Eigenschaften erzeugt werden, die nicht nur wasserabweisend (hydrophob), sondern auch öl- und fettabweisend (oleophob) sind und somit eine verbesserte Schutzwirkung besitzen. Die erzielten Oberflächeneigenschaften bewirken ein vermindertes Anhaften von Schmutzpartikeln und somit ein gutes Reinigungsverhalten.With inorganic-organic hybrid polymers, the incorporation of functional Groups of, for example, perfluorinated silane compounds in the silicate backbone Layers with anti-adhesive properties are created that are not only water-repellent (hydrophobic), but also oil and fat repellent (oleophobic) and therefore one have improved protection. The surface properties achieved have an effect reduced adhesion of dirt particles and thus good cleaning behavior.

In einem Sol-Gel-Prozess kann z.B. durch Tauchen oder Sprühen eine Beschichtung auf der Basis von anorganisch-organischen Nanokompositen mit niedriger freier Oberflächenenergie (ca. 19 mN/m) und hoher Kratz- und Abriebfestigkeit durch fluorierte organische Gruppen als Einfachreinigungsschicht hergestellt werden.In a sol-gel process, e.g. apply a coating by dipping or spraying the basis of inorganic-organic nanocomposites with low free surface energy (approx. 19 mN / m) and high scratch and abrasion resistance thanks to fluorinated organic Groups can be produced as a single cleaning layer.

Weiterhin ist es bekannt, durch photolithographische Verfahren Oberflächen zu realisieren, die periodische Strukturen mit Abmessungen im Bereich von 1 µm bis zu 100 nm aufweisen.Furthermore, it is known to realize surfaces by means of photolithographic processes, the periodic structures with dimensions in the range from 1 µm to 100 nm exhibit.

Auch durch den Einsatz eines Systems von plasmapolymeren Dünnschichten können besonders gute Reinigungseigenschaften von Oberflächen realisiert werden. Also by using a system of plasma polymer thin films particularly good cleaning properties of surfaces can be realized.

Weiterhin ist der sogenannte Lotus-Effekt für selbstreinigende Oberflächen und insbesondere aus der EP 0 772 524 B 1 eine selbstreinigende Oberfläche bekannt, die eine künstliche Oberflächenstruktur aus Erhebungen und Vertiefungen aufweist. Dabei liegt der Abstand zwischen den Erhebungen im Bereich von 5 bis 200 µm und mindestens die Erhebungen bestehen aus hydrophoben Polymeren oder haltbar hydrophobierten Materialien, wobei die Erhebungen nicht durch Wasser oder durch Wasser mit Detergenzien ablösbar sind.Furthermore, the so-called lotus effect for self-cleaning surfaces and in particular from EP 0 772 524 B1 a self-cleaning surface is known which a has artificial surface structure from elevations and depressions. Here lies the Distance between the surveys in the range of 5 to 200 microns and at least the surveys consist of hydrophobic polymers or durable hydrophobic materials, the elevations not being detachable by water or by water with detergents are.

Aufgabe der vorliegenden Erfindung ist, die derzeit bestehenden Probleme bei der Bogenführung im Schön- und Widerdruck zu verringern, insbesondere das Reinigungsverhalten eines Zylindermantelprofils zu verbessern.The object of the present invention is to solve the problems currently existing in the To reduce sheet guiding in perfecting, especially that To improve the cleaning behavior of a cylinder jacket profile.

Diese Aufgabe wird durch ein Zylindermantelprofil mit den Merkmalen gemäß Anspruch 1 gelöst.This object is achieved by a cylinder jacket profile with the features according to claim 1 solved.

Erfindungsgemäß wird die Zylinderoberfläche mit einer Oberflächenstruktur versehen. Dabei ist es unerheblich, ob die Struktur auf der Oberfläche des Zylinders selbst oder auf einer auf dem Zylinder aufgebrachten Schicht oder Mantelung erzeugt wird. Insbesondere kann der Zylinder mit einer strukturierten Oberfläche im Spritz-, Strahl- oder Abformverfahren ausgebildet werden. Zusätzlich wird auf der strukturierten Oberfläche eine Beschichtung mit einer dünnen und niederenergetischen Leichtreinigungsschichten so vorgesehen, dass die Oberflächenstruktur im Wesentlichen in ihrer Dimension nicht beeinflusst wird.According to the invention, the cylinder surface is provided with a surface structure. It is irrelevant whether the structure is on the surface of the cylinder itself or on a layer or jacket applied to the cylinder is produced. In particular can the cylinder with a structured surface in the spray, jet or Impression processes are formed. In addition, on the structured surface a coating with a thin and low-energy light cleaning layers like this provided that the surface structure is not essentially in its dimension being affected.

Vorteilhafter Weise kann vorgesehen sein, dass die Leichtreinigungsschicht auf eine strukturierte Chromschicht aufgebracht ist. Aufgrund der geringen Stärke kann die Leichtreinigungsschicht bereits nach wenigen Umdrehungen des Druckzylinders im Kontaktbereich in den Erhebungen abgerieben sein. Die Erzeugung des hohen Gegendrucks übernimmt dann die Chromschicht, während die Druckfarbe in den Vertiefungen des Mantelprofils infolge der Leichtreinigungsschicht kaum anhaftet bzw. einfach entfernbar ist. It can advantageously be provided that the light cleaning layer is applied to a structured chrome layer is applied. Due to the low thickness, the easy cleaning layer after just a few revolutions of the impression cylinder in the Contact area in the surveys must be rubbed off. The generation of the high Back pressure then takes over the chrome layer, while the printing ink in the Depressions of the cladding profile hardly adhere due to the easy cleaning layer or is easy to remove.

Gemäß einer bevorzugten Ausführungsform ist das Zylindermantelprofil mit kalottenförmigen Erhebungen und/oder Vertiefungen ausgebildet. Dadurch ist eine gute Reinigbarkeit der Oberfläche realisierbar, wobei auch ein ausreichend hoher Gegendruck beim Druckvorgang erzielt werden kann. Außerdem kann eine derart gestaltete kanten- und stufenfreie Oberfläche einfach gleichmäßig beschichtet werden. Alternativ können jedoch auch pyramidenähnliche, zylinderförmige, kegelstumpfförmige kalottenförmig oder unregelmäßig strukturierte Erhebungen auf der Oberfläche vorgesehen werden. Auch eine Mischung der verschiedenen Strukturformen kann erfindungsgemäß eingesetzt werden.According to a preferred embodiment, the cylinder jacket profile is included dome-shaped elevations and / or depressions. This is a good one Cleanability of the surface realizable, with a sufficiently high back pressure can be achieved in the printing process. In addition, such an edge and step-free surface simply coated evenly. Alternatively, however also pyramid-like, cylindrical, frustoconical dome-shaped or irregularly structured surveys are provided on the surface. Also one Mixtures of the various structural forms can be used according to the invention.

Die strukturierte Oberfläche mit den Merkmalen gemäß der Kombination der Patentansprüche 1 bis 3 kann erfindungsgemäß den Bogen ohne Verrutschen oder Verkratzen führen und wird dabei gleichzeitig nur geringfügig verschlissen. Die auf die verschleißhemmende Chrom-Beschichtung aufgetragene niederenergetische Beschichtung dient dazu, in den Bereichen, in denen der Bogen keinen direkten Kontakt zum Zylindermantelprofil hat, möglichst wenig bis keine Farbe anzunehmen. Wenn die Leichtreinigungsschicht nicht ausreichend verschleißbeständig ist, wird sie während der Verwendung in den Kontaktbereichen mit dem Papierbogen abgetragen. Dies ist jedoch unproblematisch, da die niederenergetische Leichtreinigungsschicht vorzugsweise ihre Wirkung nur zwischen den Auflagepunkten des Bogens entfalten soll.The structured surface with the characteristics according to the combination of the Claims 1 to 3 can according to the invention the sheet without slipping or Scratch and is only slightly worn out at the same time. The on the wear-resistant chrome coating applied low-energy coating is used in areas where the bow has no direct contact with the Cylinder jacket profile has to accept little or no color. If the light cleaning layer is not sufficiently wear-resistant, it will Use removed in the contact areas with the paper sheet. However, this is unproblematic, since the low-energy light cleaning layer prefers its Effect should only develop between the support points of the arch.

Bei einer Offset-Druckmaschine ist gemäß Fig. 1 ein Plattenzylinder 10 vorgesehen, auf welchen eine Druckplatte aufgespannt ist, die die aufzudruckende Information aufweist. Nachdem Druckfarbe auf den Plattenzylinder 10 aufgetragen ist, werden die zu druckenden Bereiche auf einen Gummituchzylinder 12 übertragen. In den Druckspalt zwischen dem Gummituchzylinder 12 und einem sogenannten Druckzylinder bzw. Gegendruckzylinder 14 wird dann ein Papierbogen oder eine Papierbahn 16 geführt. Das Profil der Druckzylinderoberfläche 14 weist einen Mehrschichtaufbau auf (Fig. 2a). Dabei ist zunächst eine Nickelschicht 18 als Grundschicht mit einer kalottenförmig gestalteten Oberfläche vorgesehen, die wiederum mit einer dünnen Chromschicht 20 belegt wird. Alternativ kann die Nickelschicht 18 auch mit einer ebenen Oberfläche realisiert sein, wobei lediglich die Chromschicht 20 kalottenförmig mit gleichmäßig verteilt angeordneten Erhebungen und Vertiefungen aufgebracht ist (nicht gezeigt). Typische Abstände zwischen den Erhebungen betragen etwa zwischen 20 und 100 µm, typische Dicken der Chromschicht 5 bis 10 µm. Der Kalottenstruktur aus Chrom 20 ist als Leichtreinigungsschicht 22 eine aufgeraute Mikrostruktur überlagert, deren Stärke bevorzugt zwischen 10 nm bis 2 µm liegt und die einen, an sich bekannten Lotos-Effekt aufweist, der zu einer bekannten selbstreinigenden Wirkung führt (Fig. 2a). Diese Schicht 22 kann beispielsweise als amorphe Kohlenstoffschicht, in der Colloidtechnik oder als Sol-Gel-Lack bereitgestellt werden. Ebenso ist es möglich, die Schicht durch Abscheidung aus der Gasphase beispielsweise durch Plasmapolymerisation, Plasma unterstützte chemische Abscheidung aus der Gasphase (PE-CVD) oder ähnliche Verfahren erzeugt werden.1, a plate cylinder 10 is provided on an offset printing press which a printing plate is stretched, which has the information to be printed. After printing ink is applied to the plate cylinder 10, the ones to be printed Transfer areas to a blanket cylinder 12. In the pressure gap between the Blanket cylinder 12 and a so-called impression cylinder or impression cylinder 14 then a sheet of paper or a paper web 16 is guided. The profile of the Printing cylinder surface 14 has a multilayer structure (FIG. 2a). It is first a nickel layer 18 as a base layer with a dome-shaped Surface provided, which in turn is covered with a thin chrome layer 20. Alternatively, the nickel layer 18 can also be realized with a flat surface, wherein only the chrome layer 20 is dome-shaped with evenly distributed arrangement Elevations and depressions is applied (not shown). Typical distances between the elevations are between 20 and 100 microns, typical thicknesses of the Chrome layer 5 to 10 µm. The chrome 20 dome structure is as Light cleaning layer 22 overlays a roughened microstructure, its strength is preferably between 10 nm and 2 μm and the one known lotus effect has, which leads to a known self-cleaning effect (Fig. 2a). This layer 22 can be used, for example, as an amorphous carbon layer, in colloid technology or as a sol-gel lacquer to be provided. It is also possible to remove the layer by deposition the gas phase, for example by plasma polymerization, plasma-assisted chemical Deposition from the gas phase (PE-CVD) or similar processes can be generated.

Alternativ kann die Leichtreinigungsschicht 22 auch als vollständig glatte Mikrostruktur mit einer freien Oberflächenenergie von 10 bis 50 mN/m ausgebildet sein. Die Stärke der Leichtreinigungsschicht 22 ist so gering gewählt, dass sie das entsprechend den jeweiligen Anforderungen an den Druckzylinder 14 optimierte Oberflächenprofil der Chromschicht 20 nicht nachteilig bzw. verfälschend verändert. Dabei ist das Vorsehen der Mikrostruktur 22 an den Erhöhungen der Kalottenstruktur 22 nicht zwingend erforderlich, da an diesen Stellen eine an sich glatte Gegendruckfläche gewünscht ist. Somit ist es ausreichend, wenn die Mikrostruktur bzw. Leichtreinigungsschicht 22 lediglich in den Vertiefungen des Zylindermantelprofils vorhanden ist, wo sie ihre selbstreinigende Wirkung ausübt.Alternatively, the light cleaning layer 22 can also be a completely smooth microstructure be designed with a free surface energy of 10 to 50 mN / m. The strength of the Light cleaning layer 22 is chosen so small that it corresponds to the respective Requirements for the printing cylinder 14 optimized surface profile of the chrome layer 20 not adversely or falsely changed. The microstructure 22 is provided on the elevations of the dome structure 22 is not absolutely necessary, since on these Make a smooth counter pressure surface is desired. It is therefore sufficient if the microstructure or light cleaning layer 22 only in the recesses of the Cylinder jacket profile is present where it exerts its self-cleaning effect.

Das Einbringen der Leichtreinigungsschicht 22 nur in die vertieften Bereiche wäre applikationstechnisch jedoch nur sehr aufwendig zu lösen. Deshalb wird die Leichtreinigungsschicht 22 vollflächig auf die Chrom-Kalottenstruktur 20 aufgebracht (Fig. 2a) und durch den bloßen Einsatz des Gegendruckzylinders 14 bereits nach einigen Umdrehungen durch den mechanischen Kontakt mit dem Papierbogen 16 abgetragen (Fig. 2b). Die Oberflächenstruktur des Mantelprofils wird dabei nicht oder so wenig geändert, dass keine nachteiligen Effekte beim nachfolgenden Druckvorgang eintreten.The introduction of the light cleaning layer 22 would only be in the recessed areas However, in terms of application technology, this is only very complex to solve. Therefore the Light cleaning layer 22 applied over the entire surface of the chrome dome structure 20 (Fig. 2a) and by the mere use of the impression cylinder 14 after some Revolutions removed by the mechanical contact with the paper sheet 16 (Fig. 2 B). The surface structure of the cladding profile is not changed or is changed so little, that there are no adverse effects in the subsequent printing process.

Im Ergebnis steht also bereits nach wenigen Umdrehungen des Gegendruckzylinders 14 eine Druckzylinderoberfläche bereit, die eine Kalottenstruktur mit der zusätzlichen Leichtreinigungs-Mikrostruktur 22 aufweist. Durch die Kalottenstruktur ist sichergestellt, dass zufällig, bzw. unerwünscht auf den Druckzylinder 14 aufgebrachte Farbpartikel in die Vertiefungen der Kalottenstruktur 20 verlaufen können und entsprechend bei der Ausübung des Gegendrucks auf den Papierbogen 16 nicht auf diesen übertragen werden, da lediglich die Erhöhungen der Kalottenstruktur aus Chrom 20 gegen den Papierbogen drücken. Durch die Oberflächengestaltung der Kalottenstruktur ist sichergestellt, dass die Druckfarbe infolge der Leichtreinigungsschicht 22 möglichst abgestoßen wird, und ein Anhaften der Farbe am Gegendruckzylinder 14 vermieden ist, und zugleich ein ausreichend hoher Gegendruck durch die verschleißfreie Oberfläche aus Chrom 20 bereitgestellt ist (Fig. 2b).The result is therefore after a few revolutions of the impression cylinder 14 a printing cylinder surface ready, a dome structure with the additional Easy cleaning microstructure 22 has. The dome structure ensures that randomly or undesirably applied to the printing cylinder 14 color particles in the Wells of the dome structure 20 can run and accordingly at Exercise of counter pressure on the paper sheet 16 can not be transferred to this, because only the elevations of the dome structure made of chrome 20 against the paper sheet to press. The surface design of the spherical structure ensures that the Ink is repelled as a result of the light cleaning layer 22, and a Adhesion of the color on the impression cylinder 14 is avoided, and at the same time Sufficiently high back pressure due to the wear-free surface made of chrome 20 is provided (Fig. 2b).

Die Erfindung wurde zwar in Verbindung mit einem Gegendruckzylinder beschrieben. Es ist jedoch klar, dass sie auch bei anderen papierführenden Zylindern eingesetzt werden kann. The invention has been described in connection with an impression cylinder. It However, it is clear that they are also used with other paper-carrying cylinders can.
