Definitions
- the invention relates to a plate cylinder of a printing press with at least one tensioning rail arranged in a pit of the plate cylinder according to the preamble of claim 1.
- a plate cylinder with these features is described, for example, in German Offenlegungsschrift 3 843 395.
- a so-called flat track guide is provided for the adjustment of the tensioning rail, in which the flat underside of the tensioning rail can be adjusted on the flat top of a guide.
- These known flat web guides cannot be mastered particularly well in the forces that occur. For example, the tensioning rail can tip if large forces act on it. It is also problematic to adjust the tensioning rail in all directions of the plane mentioned, because in the prior art there is often only one adjustment possibility in the circumferential direction (tensioning direction). Adjustment in this direction in some embodiments of known fastening devices of this type necessitates readjustment in the direction perpendicular thereto (axial direction), i.e. the adjustments in these two mutually perpendicular directions are not completely independent of one another.
- the invention avoids these disadvantages. It is based on the task of proposing a fastening of a tensioning rail on a plate cylinder, which enables the tensioning rail to move freely in the entire adjustment plane.
- the tensioning rail should be stored very precisely and stably and still be able to be shifted to the desired extent in the plane mentioned so that it can be positioned precisely.
- the tensioning rail is supported on the adjustment plane by at least two spaced apart axial bearings, consisting of rolling elements arranged in an annular cage.
- the rolling elements can be formed either by balls or by rollers, wherein rollers arranged in an annular cage are also referred to as roller rings.
- the mounting or mounting of the tensioning rail takes place via at least two structural units, each with two axial bearings, which would then have to be referred to as a roller and cage assembly when using roller and cage assemblies.
- roller crown assemblies allow the tensioning rail to move freely in the adjustment plane, in all directions thereof.
- the fastening of the roller ring assemblies to the cylinder must be designed so that the roller ring assemblies can follow all movements in this plane.
- Each assembly therefore preferably has a fastening plate which can be fastened to the cylinder and which has a hole with a diameter which is larger than a fastening screw which extends through the hole and which is screwed into the tensioning rail, the fastening screw being connected to the working parts of the assembly, ie to those parts which are displaced relative to the cylinder.
- each roller ring assembly has an upper and a lower roller ring, between which the fastening plate mentioned is arranged. These units are then covered by an upper and a lower cover plate.
- two outer and one central eccentric act on the plate cylinder, by means of which the tensioning rail can be adjusted in the adjustment plane.
- the tensioning rail is adjusted in the circumferential direction via the two outer eccentrics, ie for tensioning or releasing a pressure plate attached to the tensioning rail in question and with the aid of the central eccentric, the tensioning rail can be adjusted in the axial direction. Based on geometrical considerations, it follows that the adjustments of all three eccentrics depend on one another, because they are coupled to one another by the rigid tensioning rail.
- a longitudinal groove and a transverse groove are formed on the underside of the tensioning rail, into which sliding blocks are inserted, into which the actuating ends of the eccentrics engage.
- the grooves should be provided approximately in the middle on the underside of the tensioning rail. The other ends of the eccentrics are fixed to the cylinder.
- the eccentrics can be adjusted by motor or by hand. In the case of a motorized adjustment, this should take place via a suitable control so that the operator of the machine can determine the actual positions of the eccentrics and thus also the tensioning rail at any time and can enter desired target positions in the control. Of course, this can also be provided by manually adjusting the eccentric.
- the fastening according to the invention can also be provided only on a single tensioning rail of a pressure cylinder; insofar as it is only important that the other end of the pressure plate, at which end therefore does not attack the tensioning rail designed according to the invention, is held in a suitable manner, for example via spring-loaded pins which engage in holes made in the pressure plate there, via a conventional tensioning rail and right away.
- tensioning rails designed according to the invention can also be attached to both ends of the pressure plate.
- a plate cylinder 1 with its cylinder pit 2 is indicated.
- a tensioning rail 3 is fastened in this.
- Fig. 1 also shows that a pressure plate 4 is attached to the tensioning rail, the beginning of printing is indicated at item 5.
- the tensioning rail 3 is fastened to the plate cylinder 1 by means of roller ring assemblies. These consist of a middle fastening plate 6 and an upper and a lower cover plate 7, 8. Between the fastening plate and the respective cover plate, a roller ring 9 is arranged in each case. 2 shows in particular that the roller and cage assemblies essentially consist of rolling elements 10 which are arranged in a cage on a circular ring.
- a fastening screw 11 is inserted through central through holes 12 in the cover plates 7, 8 and also through an elongated hole 13 in the fastening plate 6.
- the elongated hole is not only longer in its longitudinal direction than the shaft of the screw 11, but also transversely thereto, so that the mounting plate 6 can move in all directions relative to the screw 11.
- screws 14 are also provided, with the help of which the mounting plate and with it the entire roller and crown assembly is attached to the plate cylinder 1.
- the screw 11 is also screwed into a threaded hole 15 in the clamping rail 3.
- Fig. 3 shows a schematic plan view of the tensioning rail, the center of the printing machine being indicated at item 18.
- a longitudinal groove 19 is provided approximately in the center (cf. also FIG. 4) and also a transverse groove 20 running approximately in the center.
- the fastening plates 6 of the two roller and cage assemblies with their roller rings 9 are also indicated.
- Sliding blocks 22 are inserted into the grooves 19, 20. These are characterized by the smoothest possible surfaces and they are fitted into the grooves without play.
- the sliding blocks have center bores 23 into which pins 24 of eccentrics 25 engage.
- the pins 24 are arranged eccentrically to the cylinder parts 26 of the eccentric.
- the eccentricity is indicated in Fig. 4 at item 27. It results from the distance of the center b of the gear 29 from the axis a of the pin 24. See also FIG. 3.
- the relevant sliding block 22 is therefore displaced in its groove 19 or 20. This allows the tensioning rail in its adjustment plane II-II, ie in the direction of the two arrows 16, 17 and in all directions including an angle to it be adjusted.
- Fig. 4 is also indicated that the eccentric 25 can be adjusted via a motor 28 with gear 29.
- Fig. 3 the structurally determined distance 30 between the start of pressure 5 and the starting position 31 (rest position) of the tensioning rail is shown. Starting from this target position, the respective actual position of the tensioning rail can be calculated and set.

Abstract
Description
Die Erfindung betrifft einen Plattenzylinder einer Druckmaschine mit wenigstens einer in einer Grube des Plattenzylinders angeordneten Spannschiene nach dem Oberbegriff von Anspruch 1.The invention relates to a plate cylinder of a printing press with at least one tensioning rail arranged in a pit of the plate cylinder according to the preamble of
Einen Plattenzylinder mit diesen Merkmalen beschreibt beispielsweise die deutsche Offenlegungsschrift 3 843 395. Für die Verstellung der Spannschiene ist dort eine sogenannte Flachbahnführung vorgesehen, bei der die ebene Unterseite der Spannschiene auf der ebenen Oberseite einer Führung verstellt werden kann. Diese bekannten Flachbahnführungen können insbesondere in den dabei auftretenden Kräften nicht gut beherrscht werden. So kann es beispielsweise zu einem Kippen der Spannschiene führen, wenn an dieser große Kräfte angreifen. Auch ist es problematisch, die Spannschiene in allen Richtungen der erwähnten Ebene zu verstellen, weil beim Stand der Technik häufig nur eine Verstellmöglichkeit in Umfangsrichtung (Spannrichtung) gegeben ist. Eine Verstellung in dieser Richtung macht bei einigen Ausführungsformen bekannter derartiger Befestigungsvorrichtungen ein Nachjustieren in der dazu senkrechten Richtung (Axialrichtung) notwendig, d.h. die Verstellungen in diesen beiden zueinander senkrechten Richtungen sind nicht vollständig unabhängig voneinander.A plate cylinder with these features is described, for example, in
Die Erfindung vermeidet diese Nachteile. Ihr liegt die Aufgabe zugrunde, eine Befestigung einer Spannschiene an einem Plattenzylinder vorzuschlagen, die eine freie Bewegung der Spannschiene in der gesamten Verstellebene ermöglicht.The invention avoids these disadvantages. It is based on the task of proposing a fastening of a tensioning rail on a plate cylinder, which enables the tensioning rail to move freely in the entire adjustment plane.
Die Spannschiene soll dabei sehr genau und stabil gelagert werden und trotzdem problemlos in der erwähnten Ebene in dem gewünschten Maße verschoben werden können, so daß sie genau positioniert werden kann.The tensioning rail should be stored very precisely and stably and still be able to be shifted to the desired extent in the plane mentioned so that it can be positioned precisely.
Gelöst wird diese Aufgabe durch die Merkmale von Anspruch 1. Vorteilhafte Weiterbildungen der Erfindung ergeben sich aus den Unteransprüchen.This object is achieved by the features of
Nach der Erfindung ist somit vorgesehen, daß die Spannschiene über wenigstens zwei voneinander beabstandet angeordnete Axiallager, bestehend aus in einem ringförmigen Käfig angeordnete Wälzkörper, auf der Verstellebene abgestützt ist. Die Wälzkörper können entweder durch Kugeln oder durch Rollen gebildet sein, wobei des weiteren in einem ringförmigen Käfig angeordnete Rollen als Rollenkranz bezeichnet werden. In einer bevorzugten Ausführungsform der Erfindung erfolgt die Lagerung bzw. Befestigung der Spannschiene über wenigstens zwei Baueinheiten mit je zwei Axiallagern, die dann bei Verwendung von Rollenkränzen als Rollenkranz-Baueinheit zu bezeichnen wären.According to the invention it is thus provided that the tensioning rail is supported on the adjustment plane by at least two spaced apart axial bearings, consisting of rolling elements arranged in an annular cage. The rolling elements can be formed either by balls or by rollers, wherein rollers arranged in an annular cage are also referred to as roller rings. In a preferred embodiment of the invention, the mounting or mounting of the tensioning rail takes place via at least two structural units, each with two axial bearings, which would then have to be referred to as a roller and cage assembly when using roller and cage assemblies.
Diese Rollenkranz-Baueinheiten ermöglichen eine freie Bewegung der Spannschiene in der Verstellebene, und zwar in allen Richtungen derselben. Dabei muß die Befestigung der Rollenkranz-Baueinheiten am Zylinder so ausgebildet sein, daß die Rollenkranz-Baueinheiten allen Bewegungen in dieser Ebene folgen können.These roller crown assemblies allow the tensioning rail to move freely in the adjustment plane, in all directions thereof. The fastening of the roller ring assemblies to the cylinder must be designed so that the roller ring assemblies can follow all movements in this plane.
Bevorzugt hat daher jede Baueinheit eine Befestigungsplatte, die am Zylinder befestigt werden kann, und die ein Loch mit einem Durchmesser aufweist, der größer ist als eine Befestigungsschraube, die das Loch durchgreift und die in die Spannschiene eingeschraubt ist, wobei die Befestigungsschraube mit den arbeitenden Teilen der Baueinheit verbunden ist, d.h. mit denjenigen Teilen, die relativ zum Zylinder verschoben werden.Each assembly therefore preferably has a fastening plate which can be fastened to the cylinder and which has a hole with a diameter which is larger than a fastening screw which extends through the hole and which is screwed into the tensioning rail, the fastening screw being connected to the working parts of the assembly, ie to those parts which are displaced relative to the cylinder.
Aus Stabilitätsgründen und aus Gründen der symmetrischen Kraftaufbringung wird es bevorzugt, wenn jede Rollenkranz-Baueinheit einen oberen und einen unteren Rollenkranz aufweist, zwischen denen die erwähnte Befestigungsplatte angeordnet ist. Diese Baueinheiten sind dann durch eine obere und eine untere Deckscheibe abgedeckt.For reasons of stability and for the reason of the symmetrical application of force, it is preferred if each roller ring assembly has an upper and a lower roller ring, between which the fastening plate mentioned is arranged. These units are then covered by an upper and a lower cover plate.
Diese Baueinheiten können als solche getrennt vom Plattenzylinder montiert und dann als Ganzes in den Plattenzylinder eingesetzt und dort befestigt werden, so daß sich die Erfindung auch durch eine fühlbar vereinfachte Montage und Wartung auszeichnet.These units can be mounted as such separately from the plate cylinder and then inserted as a whole in the plate cylinder and fastened there, so that the invention is characterized by a noticeably simplified assembly and maintenance.
Vorstehend wurde ausgeführt, daß es für die Erfindung u.a. wichtig ist, daß die Spannschiene in allen Richtungen der Verstellebene verstellt werden kann.The foregoing has stated that, among other things, it is important that the tensioning rail can be adjusted in all directions of the adjustment level.
Um hier eine präzise Verstellung zu erreichen wird es bevorzugt, wenn an den Plattenzylinder zwei äußere und ein mittiger Exzenter angreifen, über die die Spannschiene in der Verstellebene verstellt werden kann. Über die beiden äußeren Exzenter wird die Spannschiene in Umfangsrichtung verstellt, d.h. zum Spannen bzw. Entspannen einer an der betreffenden Spannschiene befestigten Druckplatte und mit Hilfe des mittleren Exzenters kann die Spannschiene in axialer Richtung verstellt werden. Aufgrund geometrischer Überlegungen ergibt sich, daß die Verstellungen aller drei Exzenter voneinander abhängen, weil sie ja durch die starre Spannschiene aneinander gekoppelt sind.In order to achieve a precise adjustment here, it is preferred if two outer and one central eccentric act on the plate cylinder, by means of which the tensioning rail can be adjusted in the adjustment plane. The tensioning rail is adjusted in the circumferential direction via the two outer eccentrics, ie for tensioning or releasing a pressure plate attached to the tensioning rail in question and with the aid of the central eccentric, the tensioning rail can be adjusted in the axial direction. Based on geometrical considerations, it follows that the adjustments of all three eccentrics depend on one another, because they are coupled to one another by the rigid tensioning rail.
Hierfür wird es bevorzugt, wenn an der Unterseite der Spannschiene eine Längsnut sowie eine Quernut ausgebildet sind, in die Gleitsteine eingesetzt sind, in die die Betätigungsenden der Exzenter eingreifen. Die Nuten sollen etwa mittig an der Unterseite der Spannschiene vorgesehen sein. Die anderen Enden der Exzenter sind zylinderfest.For this purpose, it is preferred if a longitudinal groove and a transverse groove are formed on the underside of the tensioning rail, into which sliding blocks are inserted, into which the actuating ends of the eccentrics engage. The grooves should be provided approximately in the middle on the underside of the tensioning rail. The other ends of the eccentrics are fixed to the cylinder.
Die Exzenter können motorisch oder von Hand verstellt werden. Bei einer motorischen Verstellung soll diese über eine geeignete Steuerung erfolgen, so daß die Bedienungsperson der Maschine jederzeit die Istlagen der Exzenter und damit auch der Spannschiene feststellen kann und gewünschte Sollagen in die Steuerung eingeben kann. Dies kann natürlich auch bei einer ebenfalls möglichen Verstellung der Exzenter von Hand vorgesehen sein.The eccentrics can be adjusted by motor or by hand. In the case of a motorized adjustment, this should take place via a suitable control so that the operator of the machine can determine the actual positions of the eccentrics and thus also the tensioning rail at any time and can enter desired target positions in the control. Of course, this can also be provided by manually adjusting the eccentric.
Es sei auch erwähnt, daß die erfindungsgemäße Befestigung auch nur an einer einzigen Spannschiene eines Druckzylinders vorgesehen sein kann; insoweit ist es lediglich wichtig, daß das andere Ende der Druckplatte, an welchem Ende also nicht die erfindungsgemäß ausgebildete Spannschiene angreift, auf geeignete Weise gehalten wird, beispielsweise über federbelastete Stifte, die in dort in der Druckplatte angebrachte Löcher eingreifen, über eine herkömmliche Spannschiene und so fort. Es können aber auch erfindungsgemäß ausgebildete Spannschienen an beiden Enden der Druckplatte befestigt werden.It should also be mentioned that the fastening according to the invention can also be provided only on a single tensioning rail of a pressure cylinder; insofar as it is only important that the other end of the pressure plate, at which end therefore does not attack the tensioning rail designed according to the invention, is held in a suitable manner, for example via spring-loaded pins which engage in holes made in the pressure plate there, via a conventional tensioning rail and right away. However, tensioning rails designed according to the invention can also be attached to both ends of the pressure plate.

In Fig. 1 ist ein Plattenzylinder 1 mit seiner Zylindergrube 2 angedeutet. In dieser ist eine Spannschiene 3 befestigt. Fig. 1 zeigt auch, daß an der Spannschiene eine Druckplatte 4 befestigt ist, deren Druckanfang bei Pos. 5 angedeutet ist.In Fig. 1, a
Die Befestigung der Spannschiene 3 am Plattenzylinder 1 erfolgt über Rollenkranz-Baueinheiten. Diese bestehen aus einer mittleren Befestigungsplatte 6 und einer oberen sowie einer unteren Deckscheibe 7, 8. Zwischen der Befestigungsplatte und der jeweiligen Deckscheibe ist jeweils ein Rollenkranz 9 angeordnet. Insbesondere Fig. 2 läßt erkennen, daß die Rollenkränze im wesentlichen aus Wälzkörpern 10 bestehen, die in einem Käfig auf einem Kreisring angeordnet sind.The tensioning
Eine Befestigungsschraube 11 ist durch mittige Durchgangslöcher 12 in den Deckscheiben 7, 8 gesteckt sowie auch durch ein Langloch 13 in der Befestigungsplatte 6. (Das Langloch ist nicht nur in seiner Längsrichtung länger als der Schaft der Schraube 11, sondern auch quer dazu, so daß sich die Befestigungsplatte 6 in ihrer Ebene allseits relativ zur Schraube 11 bewegen kann.)A
An den Enden der Befestigungsplatte 6 sind außerdem Schrauben 14 vorgesehen, mit deren Hilfe die Befestigungsplatte und mit ihr die gesamte Rollenkranz-Baueinheit am Plattenzylinder 1 befestigt ist. Die Schraube 11 ist außerdem in ein Gewindeloch 15 in der Spannschiene 3 eingeschraubt.At the ends of the
Wirkt auf die Spannschiene eine Kraft in einer beliebigen Richtung ihrer Verstellebene ein (die Verstellebene ist die Ebene II-II in Fig. 1), so wird durch die beschriebene Konstruktion erreicht, daß sich die Spannschiene - innerhalb der durch die Größe des Langlochs 13 gegebenen Grenzen - frei in dieser Ebene bewegen kann. Dies ist in Fig. 2 angedeutet, wo strichpunktiert mögliche seitliche Lagen des Rollenkranzes 9 bei Pos. 9a bzw. 9b angedeutet sind. Ebenso sind in Fig. 2 mögliche Positionen der Schraube 11 bzw. ihres Schraubenschaftes bei Pos. 11a und 11b angedeutet. Der Verstellweg zwischen diesen Positionen 11a, 11b ist in Fig. 2 bei Pos. 16 eingezeichnet.If a force acts on the tensioning rail in any direction of its adjustment plane (the adjustment plane is plane II-II in FIG. 1), the construction described achieves that the tensioning rail - within the given by the size of the
Ganz entsprechend ist auch eine Verschiebung rechtwinklig zum Pfeil 16 möglich und damit auch in allen Richtungen dieser Verstellebene II-II.Correspondingly, a shift at right angles to
Dies geht auch aus Fig. 3 hervor, wo die Verstellung in Richtung des Pfeiles 16 zum Spannen bzw. Lösen der Druckplatte eingezeichnet ist und die dazu senkrechte Verstellrichtung in Richtung des Pfeiles 17, die also eine axiale Verstellung der Spannschiene bewirkt und damit eine Korrektur des Seitenregisters.This is also apparent from Fig. 3, where the adjustment in the direction of
Fig. 3 zeigt eine schematische Draufsicht auf die Spannschiene, wobei die Mitte der Druckmaschine bei Pos. 18 angedeutet ist. An der Unterseite der Spannschiene ist etwa mittig eine Längsnut 19 vorgesehen (vgl. auch Fig. 4) sowie ebenfalls etwa mittig verlaufend eine Quernut 20. In Fig. 3 sind auch die Befestigungsplatten 6 der beiden Rollenkranz-Baueinheiten mit ihren Rollenkränzen 9 angedeutet.Fig. 3 shows a schematic plan view of the tensioning rail, the center of the printing machine being indicated at

Die Gleitsteine haben Mittenbohrungen 23, in die Zapfen 24 von Exzentern 25 eingreifen. Die Zapfen 24 sind exzentrisch zu den Zylinderteilen 26 der Exzenter angeordnet. Die Exzentrizität ist in Fig. 4 bei Pos. 27 angedeutet. Sie ergibt sich durch den Abstand der Mitte b des Getriebes 29 von der Achse a des Zapfens 24.

Dreht man die Exzenter 25, so verschiebt sich daher der betreffende Gleitstein 22 in seiner Nut 19 bzw. 20. Dadurch kann die Spannschiene in ihrer Verstellebene II-II, d.h. in Richtung der beiden Pfeile 16, 17 und in allen dazu einen Winkel einschließenden Richtungen verstellt werden.If the eccentric 25 is rotated, the relevant sliding
