Description
Diese Erfindung bezieht sich auf ein Verfahren zum Herstellen van Kunststoff zylindern, wie im Oberbegriff des Hauptanspruchs beschrieben. Das Patent bezieht sich auch auf den durch dieses Verfahren erhaltenen Zylinder.This invention relates to a method for producing plastic cylinders as described in the preamble of the main claim. The patent also relates to the cylinder obtained by this method.
Es sind viele Verfahren zum Erzeugen von Kunststoffdruckzylindern vorgeschlagen worden, jedoch sind solche bekannten Verfahren extrem kompliziert und schwierig umzusetzen, insbesondere in bezug auf das Beschichten des zugrundeliegenden Kunststoffzylinders mit Metall, wie sich z.B. aus dem US-Patent 4 503 769 im Namen von Andersen Dennis ergibt. Zusätzlich sind durch herkömmliche Verfahren erzeugte Zylinder von geringer Zuverlässigkeit oder in der Tat unzuverlässig.Many methods have been proposed for producing plastic printing cylinders, but such known methods are extremely complicated and difficult to implement, particularly with regard to coating the underlying plastic cylinder with metal, as is evident, for example, from US Patent 4,503,769 in the name of Andersen Dennis. In addition, cylinders produced by conventional methods are of low reliability or indeed unreliable.
Wie wohlbekannt ist, sind die gegenwärtig verwendeten Zylinder guter Zuverlässigkeit solche von einer Stahlkonstruktion, und selten aus Aluminium, und so entstehen verschiedene Probleme einschließlich derjenigen mit ihrem Gewicht und mit ihrem Erfordernis für ein dynamisches Auswuchten. Weitere Nachteile sind dem Fachmann auf dem Gebiet wohlbekannt.As is well known, the cylinders currently used with good reliability are those of steel construction, and rarely of aluminum, and so various problems arise, including those related to their weight and their need for dynamic balancing. Other disadvantages are well known to those skilled in the art.
NL-A-8 302 811 beschreibt einen Druckzylinder oder Zylinder zum Drucken, der einen Kernzylinder, eine Lage aus flexiblem Material um einem solchen Zylinder, eine um die Lage angeordnete Schale aufweist und eine Anzahl von Klischees oder Druckformen (Druckgießformen) trägt.NL-A-8 302 811 describes a printing cylinder or cylinder for printing comprising a core cylinder, a layer of flexible material around such cylinder, a shell arranged around the layer and carrying a number of clichés or printing forms (die casting molds).
Der Kernzylinder hat Drehzapfen, an denen Lager und ein Antriebszahnrad montiert sind. Alle diese Teile sind aus nicht defomierbarem Material hergestellt, wie Metall oder synthetischem Material.The core cylinder has pivot pins on which bearings and a drive gear are mounted. All these parts are made of non-deformable material, such as metal or synthetic material.
Die Lage um den Kern ist aus leicht flexiblem Material gemacht, wie einem schaumähnlichen Material, z.B. Polyurethanschaum mit offenen Zellen; die Lage ist mit dem Kern mittels eines Klebstoffs verbunden.The layer around the core is made of slightly flexible material, such as a foam-like material, e.g. open cell polyurethane foam; the layer is bonded to the core by means of an adhesive.
Die Schale um die Lage ist aus nicht deformierbarem Material wie einem Metall oder synthetischem Material hergestellt. Sie trägt die aus gummielastischem Material oder Photopolymermaterial gemachten Druckformen, wobei die Druckformen an der Schale mittels eines zweiseitigen Klebebandes verbunden sind. Die Schale ist mit der synthetischen Schaumlage nicht verbunden, sondern ist darum herum unter einem leichten Kontaktdruck dicht angeordnet und wird mittels Reibungskräften, die während der Verwendung des Druckzylinders entstehen, an ihrem Platz gehalten.The shell around the layer is made of non-deformable material such as a metal or synthetic material. It supports the printing forms made of rubber-elastic material or photopolymer material, the printing forms being connected to the shell by means of a two-sided adhesive tape. The shell is not connected to the synthetic foam layer, but is tightly arranged around it under a light contact pressure and is held in place by means of frictional forces that arise during use of the printing cylinder.
Die vorbekannte Lösung hat viele Nachteile. Insbesondere hat sie eine Anzahl von Teilen (Kern, Lage, Schale), die voneinander in einer sehr gut definierten Weise getrennt sind, und dies kann während der Verwendung des Zylinders gefährliche Relativbewegungen zwischen den Teilen verursachen, die der Druckqualität abträglich sind.The previously known solution has many disadvantages. In particular, it has a number of parts (core, layer, shell) that are separated from each other in a very well-defined way and this can cause dangerous relative movements between the parts during use of the cylinder, which are detrimental to the print quality.
Es ist eine Aufgabe der vorliegenden Erfindung, ein Verfahren zum Herstellen von Zylindern zum Drucken im allgemeinen und insbesondere für Tiefdruck und Flexodruck zu schaffen, das unter Verwendung einer geeigneten Vorrichtung sehr einfach durchzuführen ist.It is an object of the present invention to provide a method for producing cylinders for printing in general and in particular for gravure printing and flexographic printing, which is very easy to carry out using a suitable device.
Eine weitere Aufgabe ist es, ein Verfahren des zuvor erwähnten Typs zu schaffen, das es ermöglicht, Kunststoffdruckzylinder zu erzeugen, die eine maximale Zuverlässigkeit und ein niedriges Gewicht haben, so daß sie leicht gehandhabt und gelagert werden können.A further object is to provide a process of the type mentioned above which makes it possible to produce plastic printing cylinders which have maximum reliability and low weight so that they can be easily handled and stored.
Eine weitere Aufgabe ist es, ein Verfahren zu schaffen, das die Produktion eines Kunststoffdruckzylinders ermöglicht, dessen Durchmesser während seiner Produktion nach Wunsch variiert werden kann, ohne daß dabei besondere Schwierigkeiten auftreten.A further task is to create a process that enables the production of a plastic printing cylinder whose Diameter can be varied as desired during production without causing any particular difficulties.
Diese und weitere Ziele der Erfindung, die einem Fachmann auf dem Gebiet aus der folgenden Beschreibung klar werden, werden durch ein Verfahren erreicht, wie es im kennzeichnenden Teil des Hauptanspruchs ausgeführt ist.These and other objects of the invention, which will become clear to a person skilled in the art from the following description, are achieved by a method as set out in the characterizing part of the main claim.
Die Stufen des erfindungsgemäßen Verfahrens ergeben sich aus dem folgenden Beispiel.The steps of the process according to the invention are shown in the following example.
Eine Glasfaserware oder ein mit Epoxydharz imprägniertes Garn wird um einen perfekt zylindrischen Stahldorn mit einer geschliffenen, feingeschliffenen und chromplatierten Oberfläche gewunden, bis eine Dicke zwischen 1,5 und 2 mm erreicht ist. Die Struktur wird dann auf herkömmliche Weise bei einer Temperatur zwischen 80ºC und 120ºC polymerisiert.A fiberglass fabric or yarn impregnated with epoxy resin is wound around a perfectly cylindrical steel mandrel with a ground, honed and chrome-plated surface until a thickness of between 1.5 and 2 mm is reached. The structure is then polymerized in the conventional way at a temperature of between 80ºC and 120ºC.
Das resultierende Rohr wird dann auf dem Zentralschaft einer Gießform montiert, die aus einem Zylinder besteht, in dem der Schaft zentral angeordnet ist, und die eine perfekt geschliffene und feingeschliffene innere Oberfläche hat. Die Giesform wird dicht geschlossen, und eine Quantität an Polyurethan wird eingeführt, so daß das endgültige expandierte Produkt eine Dichte von 0,480 kg/dm³ hat, wobei das Polyurethan durch Mischen von Isocyanat und Polyol in stöchiometrischem Verhältnis in einer Mischmaschine zubereitet wird.The resulting tube is then mounted on the central shaft of a mold consisting of a cylinder in which the shaft is centrally located and which has a perfectly ground and polished internal surface. The mold is tightly closed and a quantity of polyurethane is introduced so that the final expanded product has a density of 0.480 kg/dm3, the polyurethane being prepared by mixing isocyanate and polyol in stoichiometric ratio in a mixer.
Sowohl die Komponenten als auch die Form werden bei 20 bis 35ºC temperaturgeregelt und vorzugsweise bei 30ºC.Both the components and the mold are temperature controlled at 20 to 35ºC, and preferably at 30ºC.
Beim Entfernen der aus dem Rohr und der expandierten Beschichtung bestehenden Struktur aus der Form ist die Oberfläche dieser Beschichtung infolge der Wirkung der inneren Oberfläche der Form perfekt glatt. Die Struktur wird auf perfekte Zylindrizität überprüft und kann geschliffen werden, falls erforderlich, bis sie von korrekter Geometrie ist.When the structure consisting of the tube and the expanded coating is removed from the mold, the surface of this coating is perfectly smooth due to the action of the inner surface of the mold. The structure is brought to perfect cylindricity checked and can be ground if necessary until it is of correct geometry.
Die erhaltene Struktur kann durch Auftragen eines auf Silber oder Nickel basierenden Anstrichs durch Sprühen oder Streichen auf eine Dicke von 200 uc elektrisch leitend gemacht werden. Dann wird in einem Galvanisiertank Kupfer mit einer Dicke aufgetragen, die ausreicht, um das erforderliche Gravieren der Zylinderoberfläche zu ermöglichen, wobei diese Dicke vorzugsweise 500 uc beträgt.The structure obtained can be made electrically conductive by applying a silver or nickel based paint by spraying or brushing to a thickness of 200 uc. Copper is then deposited in a plating tank to a thickness sufficient to allow the required engraving of the cylinder surface, this thickness preferably being 500 uc.
Die Dicke der expandierten Polyurethanschicht kann gemäß den Erfordernissen variiert werden, ohne die Abmessungen des inneren Rohrs zu ändern, um es zu ermöglichen, daß Zylinder von variablem äußeren Durchmesser auf demselben standardisierten Halteschaft montiert werden können.The thickness of the expanded polyurethane layer can be varied according to requirements without changing the dimensions of the inner tube, to enable cylinders of variable external diameter to be mounted on the same standardized support shaft.
