Description

Die Erfindung betrifft ein Walzenschloß für eine Gummiwalze einer Druckmaschine mit Verstellmöglichkeit der Achse der Gummiwalze achsparallel in einer Ebene senkrecht zur Richtung ihrer Achse, wobei die Gummiwalze mit Druck an wenigtens einer maschinenfesten Stahlwalze zur Anlage gebracht werden kann bzw. von ihr abgestellt werden kann und die Gummiwalze an ihren beiden Enden Walzenlager hat, die in den Walzenschlössern gelagert sind.The invention relates to a roller lock for a rubber roller of a printing machine with the possibility of adjusting the axis of the rubber roller axially parallel in a plane perpendicular to the direction of its axis, the rubber roller can be brought into contact with pressure on at least one machine-fixed steel roller or can be turned off by it and the Rubber roller has roller bearings at both ends, which are stored in the roller locks.

Bei derartigen Gummiwalzen (Zwischenwalzen) eines Farbwerks einer Druckmaschine besteht stets das Problem, die Gummiwalze nach einem Ausbau wieder in der richtigen Lage in die Maschine einzubauen, in der sie also mit dem notwendigen Druck an den beiden ihr zugeordneten, maschinenfesten stahlwalzen anliegt. Soweit bekannt, gibt es für dieses Problem bisher noch keine zufriedenstellende Lösung, die das Auswechseln der Gummiwalze und ihr Wiedereinsetzen in die richtige Position mit wenig Aufwand ermöglicht.In such rubber rollers (intermediate rollers) of an inking unit of a printing press, there is always the problem of installing the rubber roller again in the correct position in the machine after removal, in which it therefore rests with the necessary pressure on the two machine-fixed steel rollers assigned to it. As far as is known, there is as yet no satisfactory solution to this problem, which enables the rubber roller to be replaced and replaced in the correct position with little effort.

Zum Stand der Technik sei auch hingewiesen auf die DE-OS 39 15 848, die vorschlägt, lediglich eines der beiden Walzenlager über einen Exzenter zu verstellen. Eine achsparallele Verstellung wird damit also nicht erreicht. Die Verstellung erfolgt dort über einen Exzenter. Die einmal eingestellte Lage muß durch Anziehen einer Schraube gesichert werden. Ein sanftes, schonendes Einsetzen der Walze in ihr Walzenschloß ist dort aber nicht vorgesehen.Regarding the prior art, reference is also made to DE-OS 39 15 848, which proposes to adjust only one of the two roller bearings via an eccentric. An axially parallel adjustment is therefore not achieved. The adjustment takes place there via an eccentric. The position once set must be secured by tightening a screw. A gentle, gentle insertion of the roller into its roller lock is not provided there.

Aus der DE-A 413 079 ist ein Walzenschloß für Farbwalzen bekannt, das als vollschaliges Lager mit Exzenterbohrung ausgebildet ist. Ein Ringbund besitzt eine konzentrisch zugeordnete Hülse, welche durch Verdrehen ein vollschaliges (geschlossenes) Lager für den Zapfen der Farbwalzen bildet.From DE-A 413 079 a roller lock for ink rollers is known, which is designed as a full-shell bearing with an eccentric bore. A ring collar has a concentrically assigned sleeve which, when twisted, forms a full-shell (closed) bearing for the journal of the inking rollers.

Der Erfindung liegt daher die Aufgabe zugrunde, ein Walzenschloß für eine Gummiwalze einer Druckmaschine vorzuschlagen, mit dem die Achse der Gummiwalze schonend und ohne Beschädigung des Walzenlagers (Kugellager) in die Betriebslage gebracht werden kann. Der Ein- und Ausbau der Gummiwalze soll leicht möglich sein, und die Betriebsstellung soll einfach und sicher sowie reproduzierbar wieder angefahren werden können.The invention is therefore based on the object of proposing a roller lock for a rubber roller of a printing press, with which the axis of the rubber roller can be brought into the operating position gently and without damaging the roller bearing (ball bearing). The installation and removal of the rubber roller should be easy, and the operating position should be easy, safe and reproducible.

Zur Lösung dieser Aufgabe ist die Erfindung dadurch gekennzeichnet, daß das Walzenschloß eine maschinenfeste Stützschale aufweist, die sich über einen Winkel von etwa 90° erstreckt, und zwar unten an der der Stahlwalze abgewandten Seite des Walzenschlosses, und daß am Walzenschloß ein Klemmring vorgesehen ist, der um die Stützschale drehbar ist und der mit seiner Innenfläche, ausgehend von einer unteren, nicht aktiven Lage, in eine seitliche Klemmstellung abgewandt von der Stahlwalze verdreht werden kann, in der er die Gummiwalze über das Walzenlager an die Stahlwalze andrückt.To achieve this object, the invention is characterized in that the roller lock has a machine-fixed support shell which extends over an angle of approximately 90 °, at the bottom on the side of the roller lock facing away from the steel roller, and in that a clamping ring is provided on the roller lock, which is rotatable about the support shell and which can be turned with its inner surface, starting from a lower, inactive position, into a lateral clamping position facing away from the steel roller, in which it presses the rubber roller onto the steel roller via the roller bearing.

Zum Einsetzen der Gummiwalze muß man diese somit lediglich auf die obere innere Kante der maschinenfesten Stützschale auflegen. In dieser Lage wird die Gummiwalze zwar an der Stahlwalze anliegen, aber noch nicht mit dem notwendigen Druck. Um dies zu erreichen, d.h. um die Gummiwalze in ihre Betriebslage im Maschinenzug zu bringen, wird anschließend der Klemmring zumindest in seine seitliche Klemmstellung verdreht, vorzugsweise über diese seitliche Klemmstellung hinaus in eine obere Klemmstellung, wobei das Walzenlager über die Kante der Stützschale nach unten abrollt.To insert the rubber roller you only have to place it on the upper inner edge of the machine-fixed support shell. In this position, the rubber roller will rest against the steel roller, but not yet with the necessary pressure. To achieve this, i.e. in order to bring the rubber roller into its operating position in the machine train, the clamping ring is then rotated at least into its lateral clamping position, preferably beyond this lateral clamping position into an upper clamping position, the roller bearing rolling down over the edge of the support shell.

In der seitlichen bzw. oberen Klemmstellung übt der Klemmring mit seiner Innenfläche einen Druck auf das Walzenlager aus derart, daß das Walzenlager und mit ihm die gesamte Gummiwalze mit dem notwendigen und definierten Druck an die Stahlwalze angedrückt wird. Dies erfolgt an beiden Enden der Achse der Gummiwalze, d.h. in beiden Walzenschlössern, so daß dadurch die Gummiwalze achsparallel verstellt wird. Mit Hilfe des Klemmrings kann die Gummiwalze an die betreffende Stahlwalze angedrückt werden, weil die Stützschale zur Seite der Stahlwalze offen ist. In der oberen Klemmstellung wird die Gummiwalze dann auch an eine ggfs. vorhandene, untere, ebenfalls maschinenfeste Stahlwalze angedrückt.In the lateral or upper clamping position, the inner surface of the clamping ring exerts pressure on the roller bearing from such that the roller bearing and with it the entire rubber roller is pressed against the steel roller with the necessary and defined pressure. This is done at both ends of the axis of the rubber roller, ie in both roller locks, so that the rubber roller is adjusted axially parallel. With the help of the clamping ring, the rubber roller can be pressed onto the relevant steel roller because the support shell is open to the side of the steel roller. In the upper clamping position, the rubber roller is then also pressed onto a possibly existing, lower, also machine-resistant steel roller.

Ein wesentliches Merkmal der Erfindung besteht also darin, daß dieser so profiliert bzw. angeordnet ist, daß beim Verdrehen des Klemmrings in die seitliche bzw. in die obere Klemmstellung Teile des Klemmrings auf das betreffende Walzenlager der Gummiwalze einen Druck ausüben. Dies kann man, wie erwähnt, über eine entsprechende Profilierung der Innenfläche des Klemmrings und/oder über eine entsprechende Anordnung des Klemmrings erreichen.An essential feature of the invention is that it is profiled or arranged so that when the clamping ring is turned into the lateral or the upper clamping position, parts of the clamping ring exert a pressure on the roller bearing of the rubber roller in question. As mentioned, this can be achieved by appropriate profiling of the inner surface of the clamping ring and / or by an appropriate arrangement of the clamping ring.

Diesbezüglich wird es bevorzugt, wenn die Innenfläche des Klemmrings kreisförmig profiliert ist, wobei der Mittelpunkt dieses Kreises gegenüber der Achse der Stützschale versetzt ist. Durch diese Anordnung erreicht man die gewünschte Klemmwirkung des Klemmrings in den Klemmlagen der Gummiwalze zu den beiden Stahlwalzen.In this regard, it is preferred if the inner surface of the clamping ring has a circular profile, the center of this circle being offset with respect to the axis of the support shell. This arrangement achieves the desired clamping effect of the clamping ring in the clamping positions of the rubber roller with the two steel rollers.

Bezüglich der Stützschale wird es bevorzugt, wenn ihre Innenfläche kreisförmig profilierrt ist, wobei der Mittelpunkt dieses Kreises auf der Achse der Gummiwalze (in der eingeklemmten Lage) liegt. Das Abrollen der Walzenlager an den Stützschalen erfolgt somit besonders sanft, nämlich über einen Kreisbogen.With regard to the support shell, it is preferred if its inner surface has a circular profile, the center of this circle being on the axis of the rubber roller (in the clamped position). The rolling of the roller bearings on the support shells is therefore particularly smooth, namely via a circular arc.

Zum Verdrehen des Klemmrings soll dieser eine geeignete Handhabe haben, beispielsweise an der Außenseite eine Rändelung oder auch Einstecklöcher für ein stabförmiges Werkzeug.To turn the clamping ring, it should have a suitable handle, for example knurling on the outside or also insertion holes for a rod-shaped tool.

Der Klemmring sollte sich über einen Winkel von etwa 180° erstrecken, weil er dann sowohl in der seitlichen wie auch in der oberen Klemmlage aktiv sein kann.The clamping ring should extend over an angle of approximately 180 °, because it can then be active both in the lateral and in the upper clamping position.

Die Erfindung wird im folgenden anhand eines Ausführungsbeispiels näher erläutert, aus dem sich weitere wichtige Merkmale ergeben. Es zeigt:

Fig. 1 -
eine Stirnansicht der wesentlichen Bauteile eines erfindungsgemäßen Walzenschlosses, wobei die Gummiwalze auf das Walzenschloß aufgelegt ist. Angedeutet sind außerdem eine rechte, feststehende Stahlwalze und eine untere, ebenfalls feststehende Stahlwalze;
Fig. 2 -
die Situation nach Fig. 1, wobei der Klemmring gegenüber Fig. 1 im Uhrzeigersinn um 90° gedreht ist;
Fig. 3 -
dieselbe Situation, wobei der Klemmring um 180° gedreht und die Endstellung erreicht ist.
The invention is explained in more detail below on the basis of an exemplary embodiment from which further important features result. It shows:
Fig. 1 -
an end view of the essential components of a roller lock according to the invention, wherein the rubber roller is placed on the roller lock. Also indicated are a right, fixed steel roller and a lower, also fixed steel roller;
Fig. 2 -
the situation of Figure 1, wherein the clamping ring is rotated 90 ° clockwise relative to Figure 1;
Fig. 3 -
same situation, with the clamping ring turned by 180 ° and the end position reached.

Fig. 1 zeigt ein Walzenschloß mit einer maschinenfesten Stützschale 1, die zur Verdeutlichung schraffiert eingezeichnet ist. Außerdem ist ein Klemmring 2 vorgesehen.Fig. 1 shows a roller lock with a machine-fixed support shell 1, which is shown hatched for clarity. A clamping ring 2 is also provided.

In Fig. 1 ist der Klemmring 2 in seiner nicht aktiven Ausgangslage mit durchgezogenen Linien angedeutet (soweit er nicht von der Stützschale verdeckt ist). Der Klemmring 2 erstreckt sich über einen Winkel von etwa über 180°. Der Drehpunkt des Klemmrings 2 ist identisch mit dem Mittelpunkt 19 der Stützschale 1.In Fig. 1, the clamping ring 2 is indicated in its inactive starting position with solid lines (insofar as it is not covered by the support shell). The clamping ring 2 extends over an angle of approximately over 180 °. The pivot point of the clamping ring 2 is identical to the center 19 of the support shell 1.

Der Mittelpunkt 6 der Innenfläche 16 des Klemmrings 2 ist, bezogen auf den Drehpunkt 19 des Klemmrings (und den Mittelpunkt 19 der Stützschale) nach außen versetzt. Beim Drehen des Klemmrings wandert der Mittelpunkt 6 also auf einen Kreis (mit dem Mittelpunkt 19).The center 6 of the inner surface 16 of the clamping ring 2 is offset to the outside with respect to the pivot 19 of the clamping ring (and the center 19 of the support shell). When the clamping ring is rotated, the center 6 thus moves to a circle (with the center 19).

Aus dieser Ausgangslage kann der Klemmring in Richtung des Pfeiles 3 verdreht werden. Fig. 1 zeigt strichpunktiert eine Zwischenstellung 2a des Klemmrings 2. In dieser Stellung berührt der Klemmring das Walzenlager 15 zuerst, und zwar an einer Berührungslinie 20, die gegenüber der Vorderkante etwasnach hinten versetzt ist, so daß das Walzenlager vom Klemmring umfaßt ist.From this starting position, the clamping ring can be turned in the direction of arrow 3. Fig. 1 shows a dot-dash line an intermediate position 2a of the clamping ring 2. In this position, the clamping ring touches the roller bearing 15 first, at a contact line 20, which is offset slightly to the rear from the front edge, so that the roller bearing is encompassed by the clamping ring.

Pos. 4 deutet die Mitte oder Achse einer Gummiwalze und damit auch des Walzenlagers an, deren Umfang bei Pos. 5 angedeutet ist. Der Drehpunkt des Klemmrings 2 ist bei Pos. 19 angedeutet.Item 4 indicates the center or axis of a rubber roller and thus also the roller bearing, the circumference of which is indicated in item 5. The pivot point of the clamping ring 2 is indicated at item 19.

Fig. 3 zeigt auch, daß der Drehpunkt 6 gegenüber der Achse 4 um ein bestimmtes Maß nach außen versetzt ist.Fig. 3 also shows that the pivot point 6 is offset to the outside by a certain amount with respect to the axis 4.

Soll eine Gummiwalze in das Walzenschloß eingesetzt werden, so setzt man das Walzenlager über die Auflagefläche 7 auf die obere, innere Abstützkante 8 der Stützschale 1 auf und das Walzenlager rollt dann durch Drehen des Klemmrings 2 (Walzenschloß) in Richtung des Pfeiles 3 über diese Abstützkante 8 der Stützschale in die sich anschließende Innenfläche 9 der Stützschale 1 nach unten und leitet somit die angestrebte Abplattung der Gummiwalze zu der Stahlwalze ein und beendet diese. Die Achse 4 der Gummiwalze legt hierbei den bei Pos. 10 angedeuteten Weg (Kreisweg mit Mittelpunkt 8) in Richtung des Pfeiles 11 zurück und kommt im Mittelpunkt 19 zum Stehen. Diese Gummiwalze ist also jetzt in das Walzenschloß eingelegt. Ihr Umfang 5 legt sich an eine erste, feststehende Stahlwalze 12 an und das Walzenlager 15 liegt auf der Innenfläche 9 der Stützschale 1 auf.If a rubber roller is to be inserted into the roller lock, the roller bearing is placed over the support surface 7 on the upper, inner support edge 8 of the support shell 1 and the roller bearing then rolls by turning the clamping ring 2 (roller lock) in the direction of arrow 3 over this support edge 8 of the support shell into the adjoining inner surface 9 of the support shell 1 and thus leads the desired flattening of the rubber roller to the steel roller and ends this. The axis 4 of the rubber roller covers the path indicated at pos. 10 (circular path with center 8) in the direction of arrow 11 and comes to a standstill in center 19. This rubber roller is now inserted in the roller lock. Its circumference 5 bears against a first, fixed steel roller 12 and the roller bearing 15 lies on the inner surface 9 of the support shell 1.

In Fig. 2 ist die jetzt erreichte Zwischenstellung gezeigt erreicht, in der die Gummiwalze 5 an der ersten Stahlwalze 12 mit der eingestellten Abplattung anliegt.In Fig. 2 the intermediate position now reached is reached, in which the rubber roller 5 rests on the first steel roller 12 with the set flattening.

Es ist eine weitere Stahlwalze 13 links unterhalb der Gummiwalze vorgesehen und die angestrebte Abplattung zu dieser Stahlwalze 13 wird in der Fig. 2 gezeigten Stellung eingeleitet, wie ein Vergleich zwischen den Fig. 1 und 2 zeigt.A further steel roller 13 is provided on the left below the rubber roller and the desired flattening to this steel roller 13 is initiated in the position shown in FIG. 2, as a comparison between FIGS. 1 and 2 shows.

In Fig. 3 ist die Endstellung (Betriebsstellung) erreicht. Der Klemmring ist jetzt um 180° gedreht und es sind die eingestellten Abplattungen zu den Stahlwalzen 12, 13 erreicht. Das Gummiwalzenlager 15 sitzt formschlüssig in der Innenfläche 9, d.h. im Walzenschloß. (Das Walzenschloß besteht aus der Stützschale 1 mit dem Klemmring 2.) Die Mitte der Gummiwalze ist identisch mit der Mitte der Stützschale. In diesem Zusammenhang sei erwähnt, daß in Fig. 1 die Mitte der Stützschale identisch war mit dem Drehpunkt 19 des Klemmringes, während in Fig. 3 die Mitte der Stützschale zusätzlich mit der Mitte der Gummiwalze zusammenfällt.In Fig. 3 the end position (operating position) is reached. The clamping ring is now turned through 180 ° and the set flattenings to the steel rollers 12, 13 have been reached. The rubber roller bearing 15 is positively seated in the inner surface 9, ie in the roller lock. (The roller lock consists of the support shell 1 with the clamping ring 2.) The center of the rubber roller is identical to the center of the support shell. In this connection it should be mentioned that in Fig. 1 the center of the support shell was identical to that Pivotal point 19 of the clamping ring, while in Fig. 3 the center of the support shell also coincides with the center of the rubber roller.

In Fig. 3 sind die beiden Abplattungen der Gummiwalze an den beiden Stahlwalzen 12, 13 bei Pos. 14 angedeutet. Die Abplattungen liegen in der Größenordnung von beispielsweise 0,1 bis 0,15 mm.In Fig. 3, the two flattenings of the rubber roller on the two steel rollers 12, 13 are indicated at item 14. The flattening is of the order of 0.1 to 0.15 mm, for example.

Die Abplattungen werden dadurch erreicht, daß der ortsfeste Mittelpunkt 19 der Stützschale 1 in seinem Abstand zur Achse 17 der ersten Stahlwalze 12 bzw. zur Achse 18 der zweiten Stahlwalze 13 kleiner ist als die Addition der Radien der Walzen 5 und 12 bzw. 5 und 13 ergibt.The flattening is achieved in that the fixed center 19 of the support shell 1 is smaller in its distance from the axis 17 of the first steel roller 12 or the axis 18 of the second steel roller 13 than the addition of the radii of the rollers 5 and 12 or 5 and 13 results.

Der Umfang des Walzenlagers ist in den Figuren bei Pos. 15 angedeutet.The circumference of the roller bearing is indicated in the figures at item 15.

Die beschriebene Anordnung ist an beiden Enden der Gummiwalze vorgesehen, so daß eine achsparallele Verstellung der Gummiwalze erreicht wird.The arrangement described is provided at both ends of the rubber roller, so that an axially parallel adjustment of the rubber roller is achieved.

Die Verschiebung des Klemmrings 2 am Walzenschloß wird beispielsweise dadurch erreicht, daß ein geschlossener Ring in einer entsprechenden Führung des Walzenschlosses über die Achse 19 verdreht werden kann und einstückig mit diesem geschlossenen Ring ist der gezeigte Klemmring 2 ausgebildet.The displacement of the clamping ring 2 on the roller lock is achieved, for example, in that a closed ring can be rotated in a corresponding guide of the roller lock via the axis 19 and the clamping ring 2 shown is formed in one piece with this closed ring.

Fig. 3 zeigt auch, daß die Berührungslinie 20 sich oben befindet und mit der Klemmung den gewünschten Druck auf die Gummiwalze ausübt.Fig. 3 also shows that the line of contact 20 is at the top and with the clamping exerts the desired pressure on the rubber roller.
