Abstract

The printing roll has a sleeve comprising a basic sleeve (1) made of glass fibre-reinforced plastics and additional layers. The roll axle and the basic sleeve are slightly tapered and the basic sleeve has an axial key (6) which engages a slot in the roll axle. Preferably the taper amounts to approximately 2 mm variation in diameter over the length of the sleeve. Additional layers for rotogravure printing comprise a layer of compressible material (2), layer of plastics foam (3), an aluminium tube (4), and an electrolytically deposited engravable copper layer (5). For flexographic printing, the outermost layer is made of a cast or rigid foam material.

Description

Die Erfindung betrifft eine Hülse nach dem Oberbegriff des Anspruchs 1.The invention relates to a sleeve according to the preamble of claim 1.

Derartige Hülsen haben sich bewährt und können in verschiedenen Dicken hergestellt werden. Diese unterschiedliche Dicken ermöglichen bei verschiedenen Mustern den Rapportausgleich und haben den Vorteil, wesentlich leichter zu sein, als Druckwalzen vergleichbaren Umfangs. Sie können daher vorteilhaft kostengünstig über weite Strecken transportiert werden.Such sleeves have proven themselves and can be manufactured in different thicknesses. These different thicknesses enable the pattern to be compensated for different patterns and have the advantage of being considerably lighter than printing rollers of comparable size. They can therefore advantageously be transported inexpensively over long distances.

Hülsen der genannten Art sind aus dem EP 0 384 104 B1 bekannt. Nachteilig bei den bekannten Hülsen ist, daß das äußere Rohr mit einem elektrisch leitenden Anstrich versehen werden muß, um durch galvanisches Überziehen eine gravierbare Oberfläche zu schaffen.Sleeves of the type mentioned are known from EP 0 384 104 B1. A disadvantage of the known sleeves is that the outer tube must be provided with an electrically conductive paint in order to create an engravable surface by electroplating.

Nachteilig ist bei diesen bekannten Hülsen unter hohen Belastungen auch ein Verdrehen der Tiefdruckachse gegenüber der Gravur möglich, wodurch es zu Rapportstörungen kommt.A disadvantage of these known sleeves under high loads is also a rotation of the gravure axis relative to the engraving, which leads to repeat errors.

Es ist demgegenüber Aufgabe der Erfindung, Hülsen zu schaffen, deren Oberfläche direkt gravierbar ist, die einfach aufgebaut sind und die eine besonders große Andruckkraft bewältigen können. Darüber hinaus sollen sie eine lange Lebensdauer aufweisen und kostengünstig herstellbar sein.In contrast, it is an object of the invention to provide sleeves whose surface can be engraved directly are simply constructed and can handle a particularly large pressure force. In addition, they should have a long life and be inexpensive to manufacture.

Rapportstörungen sollen ausgeschlossen sein, wobei die Montage und Demontage der Hülse auf der Tiefdruckachse besonders einfach sein soll.Report errors should be excluded, whereby the assembly and disassembly of the sleeve on the gravure axis should be particularly simple.

Diese Aufgabe wird erfindungsgemäß durch die Maßnahmen des kennzeichenden Teils des Anspruchs 1 gelöst.This object is achieved by the measures of the characterizing part of claim 1.

Weitere vorteilhafte Maßnahmen sind in den Unteransprüchen 1 bis 7 näher beschrieben.Further advantageous measures are described in subclaims 1 to 7.

Im folgenden wird ein Ausführungsbeispiel der Erfindung aufgrund von Zeichnungen näher beschrieben. Es zeigen:

Figur 1
im Teilschnitt eine Druckhülse gemäß der Erfindung,
Figur 2 bis 9
das Arbeitsverfahren der Vorrichtung zur Herstellung der Hülse.
In the following, an embodiment of the invention is described in more detail based on drawings. Show it:
Figure 1

Figure 2 to 9
the working method of the device for producing the sleeve.

Die erfindungsgemäße Hülse für eine Tiefdruckwalze besteht aus einer Grundhülse 1 aus glasfaserverstärkten Kunststoff, einer darauf aufgebrachten Schicht 2 aus kompressiblem Material, einer darauf aufgebrachten Distanzschicht 3 aus Kunststoffschaum, einem darauf folgenden Aluminiumrohr 4 und einer darauf aufgebrachten gravierbaren Kupferschicht 5, wobei die Hülse eine axial verlaufende Feder 6 aufweist, die in eine Nut der Tiefdruckachse eingreift.The sleeve according to the invention for a rotogravure roller consists of a base sleeve 1 made of glass fiber reinforced plastic, a layer 2 of compressible material applied thereon, a spacer layer 3 made of plastic foam applied thereon, a subsequent aluminum tube 4 and an engravable copper layer 5 applied thereon, the sleeve being an axial extending spring 6 which engages in a groove of the gravure axis.

Der Formschluß zwischen Tiefdruckachse und Hülse wird durch eine Konizität der Grundhülse und eine entsprechende der Tiefdruckachse hergestellt, die ca. 2 mm Durchmesserveränderung gemessen über die Achsenlänge beträgt.The positive connection between the gravure axis and the sleeve is produced by a taper of the base sleeve and a corresponding one of the gravure axis, the approx. 2 mm diameter change measured over the axis length.

Das Aufziehen der Hülse auf die Tiefdruckachse ist besonders einfach, wobei die Tiefdruckachse nur einseitig aufgespannt wird, die Hülse dann aufgeschoben wird und die Endposition mit vorgebbarer Kraft mechanisch eingestellt wird.The mounting of the sleeve on the gravure axis is particularly simple, the intaglio axis being spanned only on one side, the sleeve then being pushed on and the end position being set mechanically with a predeterminable force.

Zur Herstellung der Hülse werden die Grundhülse 1 und die Schicht aus kompressiblem Material 2 in das Aluminiumrohr 4 gestellt und der Zwischenraum mit der Distanzschaumschicht 3 ausgegossen.To produce the sleeve, the base sleeve 1 and the layer of compressible material 2 are placed in the aluminum tube 4 and the space with the spacer foam layer 3 is poured out.

Das eigentliche Aufschieben der Hülse kann dabei manuell erfolgen.The actual sliding of the sleeve can be done manually.

Die Vorrichtung zum Aufschieben der Hülse auf die Tiefdruckachse geht in insgesamt acht Stufen vor sich, die in den einzelnen Figuren 2 bis 9 dargestellt sind.

Figur 2:
Die Tiefdruckachse wird in zwei Auflegelager 7, 8 eingelegt.
Figur 3:
Die Tiefdruckachse wird mit einem Gegenlager 9 auf der linken Seite festgespannt.
Figur 4:
Zur Entlastung wird ein Abstützarm 10 gegen die Achse gefahren.
Figur 5:
Das rechte Auflegelager 8 wird abgesenkt. Gehalten durch das Gegenlager 9 auf der linken Seite und den Abstützarm 10 ist die Tiefdruckachse nun nach rechts hin frei.
Figur 6:
Die Hülse wird nun mit Handkraft aufgeschoben.
Figur 7:
Das rechte Auflegelager 8 fährt gegen die Achse. Der linke Abstützarm 10 fährt ab.
Figur 8:
Der rechte Schubadapter drückt nun die Hülse mit definierter Kraft in ihre Endstellung.
Figur 9:
Die Tiefdruckachse mit aufmontierter Hülse wird entnommen.
The device for pushing the sleeve onto the gravure axis proceeds in a total of eight stages, which are shown in the individual FIGS. 2 to 9.
Figure 2:
The gravure axis is placed in two support bearings 7, 8.
Figure 3:
The gravure axis is clamped with a counter bearing 9 on the left side.
Figure 4:
To relieve a support arm 10 is moved against the axis.
Figure 5:
The right support bearing 8 is lowered. Held by the counter bearing 9 on the left side and the support arm 10, the gravure axis is now free to the right.
Figure 6:
The sleeve is now pushed on by hand.
Figure 7:
The right support bearing 8 moves against the axis. The left support arm 10 moves off.
Figure 8:
The right push adapter now presses the sleeve into its end position with a defined force.
Figure 9:
The rotogravure axis with the sleeve attached is removed.

Die Demontage geschieht wie folgt:Disassembly is as follows:

Der linke Abstützarm 10 wird als Schubadapter eingesetzt. Er löst die Hülse. Der linke Abstützarm hat somit also eine Doppelfunktion (Abstützarm und Schubadapter).The left support arm 10 is used as a push adapter. He loosens the sleeve. The left support arm thus has a double function (support arm and thrust adapter).

Wie in Figur 4 gezeigt, stützt er den Kern dann ab. Ab dann erfolgt das Entnehmen der Hülse von der Tiefdruckachse analog zur Montage.As shown in Figure 4, it then supports the core. From then on, the sleeve is removed from the gravure axis in the same way as for assembly.

In einer weiteren Ausgestaltung der erfindungsgemäßen Hülse kann die außenliegende Schicht auch als Flexohülse aus einer Verguß- oder Hartschaummasse bestehen. Das Aluminiumrohr 4 kann für diesen Fall auch aus Kunststoff bzw. glasfaser- oder kohlefaserverstärktem Kunststoff bestehen. Der Aufbau der Flexohülse entspricht weiterhin der heutigen Fertigungstechnik, d.h. es handelt sich um eine Verguß- oder Hartschaummasse mit duromerer Oberfläche.In a further embodiment of the sleeve according to the invention, the outer layer can also consist of a potting or rigid foam compound as a flexo sleeve. The aluminum tube 4 can also consist of plastic or glass fiber or carbon fiber reinforced plastic in this case. The structure of the flexo sleeve still corresponds to today's manufacturing technology, i.e. it is a casting or rigid foam with a duromer surface.
