Durch die EP 0 712 725 A2 ist eine Vorrichtung zum Andrücken eines Aufzugs an einen Zylinder einer Druckmaschine mit Hilfe von mehreren, längs des Zylinders angeordneten Wälzelementen, insbesondere Rollen bekannt.By the EP 0 712 725 A2 a device for pressing an elevator to a cylinder of a printing press by means of a plurality of arranged along the cylinder rolling elements, in particular rollers known.

Die WO 01/87613 A1 beschreibt ein Verfahren und mehrere Ausführungen von einer Vorrichtung zum Andrücken eines Aufzugs an einen Zylinder einer Druckmaschine, wobei bei der Montage oder Demontage eines Aufzuges mehrere Rollen mittels eines Stellmittels gegen den Zylinder gedrückt werden. Das Stellmittel kann als ein mit einem Druckmittel beaufschlagbarer, reversibel verformbarer Hohlkörper, z. B. ein Schlauch ausgeführt sein. Durch eine Beaufschlagung des Hohlkörpers mit dem Druckmittel wird ein im Wesentlichen stempelförmig ausgebildeter steifer Rollenträger gegen die Kraft einer Feder gegen den Zylinder gedrückt. In einem Ausführungsbeispiel ist der Rollenträger als Schwinge oder als einarmiger Hebel ausgebildet. Ein anderes Ausführungsbeispiel sieht zusätzlich zu ersten voneinander beabstandeten Rollen, die für die Montage neuer Aufzüge an den Zylinder anstellbar sind, mehrere zweite Rollen vor, die zur Demontage von Aufzügen angestellt werden können. Für das Anstellen der ersten und zweiten Rollen können zwei unabhängig voneinander betätigbare Stellmittel vorgesehen sein.The WO 01/87613 A1 describes a method and several embodiments of a device for pressing an elevator to a cylinder of a printing press, wherein During assembly or disassembly of a lift several roles are pressed by means of an adjusting means against the cylinder. The actuating means can be acted upon as a reversibly deformable hollow body which can be acted upon by a pressure medium, for. B. be executed a hose.

Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung zum Führen eines Aufzugs an einen Zylinder einer Druckmaschine zu schaffen.The invention has for its object to provide a device for guiding an elevator to a cylinder of a printing press.

Die Aufgabe wird erfindungsgemäß durch die Merkmale des Anspruchs 1 gelöst.The object is achieved by the features of claim 1.

Die mit der Erfindung erzielbaren Vorteile bestehen insbesondere darin, dass jeweils ein einzelnes Wälzelement oder eine Gruppe von Wälzelementen selektiv zum Andrücken einer bestimmten Druckform verwendet werden. Überdies führt die Ausbildung des Trägers des Wälzelements als ein elastisch biegbarer Körper dazu, dass die Vorrichtung sehr flach und damit platzsparend gebaut werden kann, was bei den gegebenen Einbauverhältnissen an einer Druckmaschine sehr vorteilhaft ist. Die Vorrichtung ist schmutzunempfindlich und robuster als eine Anordnung mit einem Träger, der z. B. an einem Gelenk angebracht ist, weil ein Gelenk an dem beabsichtigten Einbauort für eine störungsfreie Funktion vor Verschmutzung wie z. B. Farbspritzer und Staub geschützt werden muß, was einen zusätzlichen Aufwand bedeutet. Außerdem wird im Zusammenwirken mit dem auf den Träger wirkenden Stellmittel kein separates Federelement benötigt, um den Träger nach einer Betätigung des Stellmittels wieder in seine ursprüngliche Position zurückzubringen, denn der Träger besitzt aufgrund seiner Ausgestaltung als einen elastisch biegbaren Körper immanent eine rückfedernde Eigenschaft. Die vorgeschlagene Vorrichtung benötigt zur Montage eines Aufzugs auf einen Zylinder gegenüber einer Vorrichtung nach dem Stand der Technik ersichtlich weniger Bauteile, insbesondere keine Einführschieber, die ein Ende des Aufzugs in einen in den Formzylinder eingebrachten Befestigungsschlitz einführen.The advantages attainable with the invention consist in particular in that in each case a single rolling element or a group of rolling elements are used selectively for pressing a specific printing plate. Moreover, the formation of the carrier of the rolling element as an elastically bendable body to the fact that the device can be built very flat and thus save space, which is very advantageous given the installation conditions of a printing press. The device is dirt-resistant and more robust than an arrangement with a carrier, the z. B. is attached to a joint, because a joint at the intended location for trouble-free function against contamination such. As splashes of paint and dust must be protected, which means an additional expense. In addition, in cooperation with the acting on the carrier actuating means no separate spring element is required to return the carrier after actuation of the actuating means back to its original position, because the carrier has due to its design as an elastically bendable body immanent a rebounding property. The proposed device requires for mounting an elevator on a cylinder relative to a device according to the prior art, less components, in particular no Einführschieber, which introduce one end of the elevator in an inserted into the form cylinder mounting slot.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird im Folgenden näher beschrieben.An embodiment of the invention is illustrated in the drawing and will be described in more detail below.

In einer Druckmaschine, z. B. einer Rollenrotationsoffsetdruckmaschine, rollt ein mit mindestens einem Aufzug 01, z. B. einer vorzugsweise biegsamen Druckform 01 belegbarer Formzylinder 02 auf einem Gegendruckzylinder 03, z. B. einem Übertragungszylinder 03 ab. Der Formzylinder 02 weist an seiner Mantelfläche 04 vorzugsweise mindestens eine längs zum Formzylinder 02 verlaufende schlitzförmige Öffnung 06 auf, in die eine an einem Ende des Aufzugs 01 angebrachte Abkantung 07 vorzugsweise formschlüssig einhängbar ist.In a printing press, z. As a web-fed rotary offset printing press, rolls with at least one elevator 01, z. B. a preferably flexible printing plate 01 assignable forme cylinder 02 on a counter-pressure cylinder 03, z. B. from a transfer cylinder 03. The forme cylinder 02 has on its lateral surface 04 preferably at least one longitudinally to the forme cylinder 02 extending slot-shaped opening 06, in which a mounted on one end of the elevator 01 fold 07 is preferably positively mounted hooked.

Beabstandet vom Zylinder 02 ist eine Halterung 08 für einen Träger 11 vorgesehen. In der bevorzugten Ausführung befindet sich vorzugsweise im Bereich vor und zwischen dem Formzylinder 02 und dem Gegendruckzylinder 03, d. h. im Spalt bzw. in dem von den Mantelflächen der Zylinder 02; 03 begrenzten Raum eine längs zu diesen Zylindern 02; 03 erstreckende Traverse 08, die z. B. ein biegesteifes Hohlprofil mit einem quadratischen Querschnitt sein kann. An dieser vorzugsweise als Traverse 08 ausgebildeten Halterung 08 ist entweder direkt oder mittels eines Verbindungsstückes 09, das z. B. eine L-förmige Leiste sein kann, mindestens ein Träger 11 angebracht, der ein erstes Ende 12 aufweist, mit dem der Träger 11 an der Traverse 08 oder am Verbindungsstück 09 verbunden ist. Die Verbindung des ersten Endes 12 des Trägers 11 mit der Halterung 08 erfolgt vorzugsweise mit einem Verbindungselement 13, das eine Schraube 13 oder ein Niet 13 sein kann. Das erste Ende 12 des Trägers 11 ist damit nicht gelenkig, insbesondere starr mit der Halterung 08 verbunden, insbesondere an der Halterung 08 eingespannt. Der Träger 11 weist eine Fläche 22 und die Halterung 08 weist eine Fläche 23 auf, wobei beide Flächen 22; 23 einander zugewandt sind (Fig. 2). Die Flächen 22; 23 sind mit einem Abstand a voneinander beabstandet angeordnet.Spaced from the cylinder 02, a holder 08 is provided for a carrier 11. In the preferred embodiment is preferably in the area before and between the forme cylinder 02 and the impression cylinder 03, ie in the gap or in the of the lateral surfaces of the cylinder 02; 03 limited space one along these cylinders 02; 03 extending cross member 08, the z. B. may be a rigid hollow profile with a square cross-section. At this preferably designed as Traverse 08 bracket 08 is either directly or by means of a connector 09, the z. B. may be an L-shaped strip, at least one carrier 11 is attached, which has a first end 12, with which the carrier 11 is connected to the cross member 08 or the connecting piece 09. The connection of the first end 12 of the carrier 11 with the holder 08 is preferably carried out with a connecting element 13, which may be a screw 13 or a rivet 13. The first end 12 of the carrier 11 is thus not articulated, in particular rigidly connected to the holder 08, in particular clamped to the holder 08. Of the Carrier 11 has a surface 22 and holder 08 has a surface 23, both surfaces 22; 23 facing each other ( Fig. 2 ). The surfaces 22; 23 are spaced apart at a distance a.

An einem dem ersten Ende 12 des Trägers 11 gegenüberliegenden zweiten Ende 16 ist ein drehbar gelagertes Wälzelement 17 derart angeordnet, dass das Wälzelement 17 bei einer Anstellung an den Formzylinder 02 auf dessen Mantelfläche 04 bzw. auf einem auf der Mantelfläche 04 aufliegenden Aufzug 01 abrollen kann (Fig. 2), wodurch eine an einem Ende des Aufzugs 01 angebrachte Abkantung 07 in eine Öffnung 06 in der Mantelfläche 04 des Zylinders 02 eingedrückt und ein Aufzug 01 an die Mantelfläche 04 des Formzylinders 02 angedrückt wird. Die Drehachse 18 des Wälzelements 17 verläuft mithin längs zum Formzylinder 02. Das Wälzelement 17 ist vorzugsweise als eine Rolle 17 oder als eine Walze 17 ausgebildet und ist in der bevorzugten Ausführung geeignet, eine an einem Ende des Aufzugs 01 angebrachte Abkantung 07 in eine Öffnung 06 des Zylinders 02 einzuführen.At a first end 12 of the support 11 opposite the second end 16, a rotatably mounted rolling element 17 is arranged such that the rolling element 17 can roll on an employment on the forme cylinder 02 on the lateral surface 04 or on a resting on the lateral surface 04 elevator 01 ( Fig. 2 ), whereby a mounted at one end of the elevator 01 fold 07 is pressed into an opening 06 in the lateral surface 04 of the cylinder 02 and an elevator 01 is pressed against the lateral surface 04 of the forme cylinder 02. The rotation axis 18 of the rolling element 17 thus extends longitudinally to the forme cylinder 02. The rolling element 17 is preferably formed as a roller 17 or as a roller 17 and is suitable in the preferred embodiment, a mounted at one end of the elevator 01 fold 07 in an opening 06th of the cylinder 02 to introduce.

Der Träger 11 selbst ist ein elastisch biegbarer, d. h. reversibel verformbarer Körper, der vorzugsweise blattförmig ausgebildet ist. So kann der Träger 11 ein an seinem ersten Ende 12 fest eingespanntes Federblech 11 sein.The carrier 11 itself is an elastically bendable, d. H. reversibly deformable body, which is preferably formed sheet-shaped. Thus, the carrier 11 may be a spring plate 11 firmly clamped at its first end 12.

Überdies ist ein Stellmittel 19 vorgesehen, wobei das Stellmittel 19 vorzugsweise als ein mit einem Druckmittel beaufschlagbarer, reversibel verformbarer Hohlkörper 19, z. B. als ein Schlauch 19 ausgeführt ist. Das Stellmittel 19 wirkt bei seiner Betätigung, d. h. z. B. bei seiner Beaufschlagung mit dem Druckmittel zum einen auf den Träger 11 und andererseits auf die Halterung 08, indem sich das Stellmittel 19 an den einander zugewandten Flächen 22; 23 der Halterung 08 und des Trägers 11 abstützt (Fig. 2). Durch die Betätigung des Stellmittels 19 wird das zweite Ende 16 des Trägers 11 in Richtung des Formzylinders 02 durch eine elastische Biegung des Trägers 11 ausgelenkt und das Wälzelement 17 an den Formzylinder 02 angestellt (Fig. 2), denn die Halterung 08 verbleibt relativ zum Zylinder 02 in Ruhe, wohingegen das zweite Ende 16 des Trägers 11 eine zum Zylinder 02 gerichtete Schwenkbewegung ausführt, wodurch sich der Abstand a der Fläche 22; 23 vergrößert. Mit Beendigung der Betätigung des Stellmittels 19 kehrt der Träger 11 aufgrund seiner Elastizität, d. h. seiner rückfedernden Eigenschaft, in seine ursprüngliche Position zurück. In der Folge ist das Wälzelement 17 von der Mantelfläche 04 des Formzylinders 02 bzw. von einem auf der Mantelfläche 04 des Formzylinders 02 aufliegenden Aufzug 01 wieder abgestellt, d. h. außer Kontakt.Moreover, an adjusting means 19 is provided, wherein the adjusting means 19 preferably as an acted upon by a pressure medium, reversibly deformable hollow body 19, for. B. is designed as a hose 19. The actuating means 19 acts in its operation, ie, for example, when it is acted upon by the pressure medium on the one hand on the carrier 11 and on the other hand on the holder 08 by the actuating means 19 on the mutually facing surfaces 22; 23 of the bracket 08 and the carrier 11 is supported ( Fig. 2 ). By actuating the actuating means 19, the second end 16 of the carrier 11 is deflected in the direction of the forme cylinder 02 by an elastic bending of the carrier 11 and the rolling element 17 is applied to the forme cylinder 02 ( Fig. 2 ), because the holder 08 remains relative to the cylinder 02 at rest, whereas the second end 16 of the carrier 11 performs a directed to the cylinder 02 pivotal movement, whereby the distance a of the surface 22; 23 enlarged. Upon completion of the actuation of the actuating means 19, the carrier 11 returns due to its elasticity, ie its spring-back property in its original position. As a result, the rolling element 17 is turned off again by the outer surface 04 of the forme cylinder 02 or by an elevator 01 resting on the outer surface 04 of the forme cylinder 02, ie out of contact.

Wenn das Stellmittel 19, wie in der Fig. 1 dargestellt, zwischen dem Träger 11 und der Traverse 08 verbaut ist, ist es vorteilhaft, z. B. am Träger 11 eine Leiste 21 anzuformen oder anzubringen, die das Stellmittel 19 vor einem unbeabsichtigten Herausrutschen oder Entfernen von seinem Anbringungsort schützt.When the actuating means 19, as in the Fig. 1 shown, is installed between the carrier 11 and the Traverse 08, it is advantageous, for. B. to form the carrier 11, a bar 21 or to install, which protects the actuating means 19 against accidental slipping out or removal from its mounting location.

Die Figuren 1 und 2 zeigen somit dieselbe beispielhafte Anordnung einer Vorrichtung zum Führen, insbesondere Andrücken eines Aufzugs 01 an einen Zylinder 02 einer Druckmaschine in zwei unterschiedlichen Betriebszuständen, nämlich in der Fig. 1 im Betriebszustand mit einem abgestellten Wälzelement 17 und in der Fig. 2 im Betriebszustand mit einem angestellten Wälzelement 17. Die vorgeschlagene Vorrichtung ist z. B. zur Montage eines Aufzugs 01 auf einem Zylinder 02 verwendbar.The FIGS. 1 and 2 Thus, the same exemplary arrangement of a device for guiding, in particular pressing an elevator 01 to a cylinder 02 of a printing machine in two different operating conditions, namely in the Fig. 1 in the operating state with a parked rolling element 17 and in the Fig. 2 in the operating state with a salaried rolling element 17. The proposed device is z. B. for mounting an elevator 01 on a cylinder 02 usable.

Für einige Anwendungen, z. B. bei einer Anordnung von mehreren Druckformen in axialer Richtung nebeneinander auf der Mantelfläche 04 des Formzylinders 02, ist es vorteilhaft, an der Traverse 08 in axialer Richtung nebeneinander mehrere Träger 11 mit jeweils mindestens einem Wälzelement 17 anzuordnen, wobei die Träger 11 unabhängig voneinander einzeln oder in Gruppen durch ihnen zugeordnete Stellmittel 19 an den Zylinder 02 an- bzw. abstellbar sind. So kann jeweils ein einzelnes Wälzelement 17 oder eine Gruppe von Wälzelementen 17 selektiv zum Andrücken einer bestimmten Druckform verwendet werden.For some applications, eg. B. in an arrangement of several printing plates in the axial direction next to each other on the lateral surface 04 of the forme cylinder 02, it is advantageous to arrange on the traverse 08 in the axial direction next to each other several carriers 11, each with at least one rolling element 17, wherein the carrier 11 independently or in groups by them associated adjusting means 19 to the cylinder 02 on or be turned off. Thus, in each case a single rolling element 17 or a group of rolling elements 17 can be used selectively for pressing a specific printing forme.
