Vorrichtung zum Führen eines Aufzugs an einen Zylinder einer DruckmaschineDevice for guiding an elevator to a cylinder of a printing press
Die Erfindung betrifft eine Vorrichtung zum Führen eines Aufzugs an einen Zylinder einer Druckmaschine gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a device for guiding an elevator to a cylinder of a printing press according to the preamble of claim 1.
Durch die DE 197 19559 A1 ist ein Vorrichtung zur Montage biegsamer Druckplatten bekannt, wobei eine Andrückrolle an einer z. B. als eine Blattfeder ausgebildeten Halterung angeordnet ist, wobei die Halterung mit einem Einführschieber verbunden ist, wobei der Einführschieber durch eine Linearbewegung an einen Formzylinder anstellbar ist und dabei ein Ende der Druckplatte in einen in den Formzylinder eingebrachten Befestigungsschlitz einführt.From DE 197 19559 A1 a device for mounting flexible printing plates is known, a pressure roller on a z. B. is arranged as a leaf spring holder, the holder being connected to an insertion slide, the insertion slide being adjustable by a linear movement on a forme cylinder and thereby inserting one end of the pressure plate into an attachment slot introduced into the forme cylinder.
Durch die EP 0712 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.EP 0712 725 A2 discloses a device for pressing an elevator onto a cylinder of a printing press with the aid of a plurality of rolling elements, in particular rollers, arranged along the cylinder.
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 stempeiförmig 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.WO 01/87613 A1 describes a method and several embodiments of a device for pressing an elevator onto a cylinder of a printing press, wherein several rollers are pressed against the cylinder by means of an actuating means during the assembly or disassembly of an elevator. The actuating means can be a reversibly deformable hollow body, for. B. a hose. By applying the pressure medium to the hollow body, a substantially roller-shaped rigid roller carrier is pressed against the force of a spring against the cylinder. In one embodiment, the roller carrier is designed as a rocker arm or as a one-armed lever. Another exemplary embodiment provides, in addition to the first rollers spaced apart from one another, which can be adjusted for the assembly of new elevators on the cylinder, several second rollers, that can be used to dismantle elevators. Two actuating means which can be actuated independently of one another can be provided for the employment of the first and second rollers.
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 die Ausbildung des Trägers des Wälzelements als ein elastisch biegbarer Körper dazu führt, 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 that can be achieved with the invention are, in particular, that the design of the support of the rolling element as an elastically bendable body means that the device can be built very flat and thus space-saving, which is very advantageous in the given installation conditions on a printing press. The device is insensitive to dirt and more robust than an arrangement with a carrier which, for. B. is attached to a joint, because a joint at the intended installation location for trouble-free function against pollution such. B. splashes of paint and dust must be protected, which means an additional effort. In addition, in cooperation with the actuating means acting on the carrier, no separate spring element is required to return the carrier to its original position after actuation of the actuating means, because the carrier inherently has a resilient property due to its configuration as an elastically bendable body. To assemble an elevator on a cylinder, the proposed device obviously requires fewer components, in particular no insertion slides, which insert one end of the elevator into a fastening slot made in the forme cylinder compared to a device according to the prior art.
Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird im Folgenden näher beschrieben. Es zeigen:An embodiment of the invention is shown in the drawing and is described in more detail below. Show it:
Fig. 1 eine Vorrichtung zum Andrücken eines Aufzugs an einen Zylinder im vom Zylinder abgestellten Betriebszustand;1 shows a device for pressing an elevator onto a cylinder in the operating state parked by the cylinder;
Fig. 2 eine Vorrichtung zum Andrücken eines Aufzugs an einen Zylinder in am Zylinder angestellten Betriebszustand.Fig. 2 shows a device for pressing an elevator against a cylinder in the operating state set on the cylinder.
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, e.g. B. a web offset printing press, rolls with at least one elevator 01, z. B. a preferably flexible printing form 01 assignable forme cylinder 02 on an impression cylinder 03, z. B. from a transfer cylinder 03. The forme cylinder 02 preferably has at least one slit-shaped opening 06 on its lateral surface 04, into which a bevel 07 attached to one end of the elevator 01 can preferably be positively 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.A holder 08 for a carrier 11 is provided at a distance from the cylinder 02. In the preferred embodiment, it is preferably located in the area in front of and between the forme cylinder 02 and the impression cylinder 03, ie in the gap or in that of the lateral surfaces of the cylinders 02; 03 limited space along these cylinders 02; 03 extending traverse 08, the z. B. can be a rigid hollow profile with a square cross section. On this preferably designed as a cross member 08 bracket 08 is either directly or by means of a connecting piece 09, the z. B. can be an L-shaped bar, 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 to the connector 09. The connection of the first end 12 of the carrier 11 to the holder 08 is preferably carried out using a connecting element 13, which can 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 on the holder 08. The Carrier 11 has a surface 22 and the holder 08 has a surface 23, both surfaces 22; 23 face each other (Fig. 2). The surfaces 22; 23 are spaced apart from each other by 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.A rotatably mounted rolling element 17 is arranged on a second end 16 opposite the first end 12 of the carrier 11 such that the rolling element 17 can roll on its lateral surface 04 or on an elevator 01 resting on the lateral surface 04 when it is positioned against the forme cylinder 02 (Fig. 2), whereby an edge 07 attached to one end of the elevator 01 is pressed into an opening 06 in the lateral surface 04 of the cylinder 02 and an elevator 01 is pressed onto the lateral surface 04 of the forme cylinder 02. The axis of rotation 18 of the rolling element 17 therefore runs longitudinally to the forme cylinder 02. The rolling element 17 is preferably designed as a roller 17 or as a roller 17 and, in the preferred embodiment, is suitable for an edging 07 attached to one end of the elevator 01 into an opening 06 of cylinder 02.
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, i.e. H. reversibly deformable body, which is preferably sheet-shaped. The carrier 11 can thus 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.In addition, an actuating means 19 is provided, the actuating means 19 preferably being a reversibly deformable hollow body 19, for. B. is designed as a hose 19. The actuating means 19 acts when it is actuated, 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, in that the actuating means 19 on the mutually facing surfaces 22; 23 of the bracket 08 and the support 11 supports (Fig. 2). By actuating the adjusting 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 placed against the forme cylinder 02 (FIG. 2), because the holder 08 remains at rest relative to the cylinder 02, whereas the second end 16 of the carrier 11 executes a pivoting movement towards the cylinder 02, as a result of which the distance a of the surface 22; 23 enlarged. When actuation of the actuating means 19 ends, the carrier 11 returns to its original position on account of its elasticity, ie its resilient property. As a result, the rolling element 17 is switched off again from the outer surface 04 of the forme cylinder 02 or from 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.If the adjusting means 19, as shown in FIG. 1, is installed between the carrier 11 and the crossmember 08, it is advantageous, for. B. on the carrier 11 to form or attach a bar 21 which protects the actuating means 19 from inadvertent slipping out or removal from its 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.FIGS. 1 and 2 thus show the same exemplary arrangement of a device for guiding, in particular pressing an elevator 01 against a cylinder 02 of a printing press in two different operating states, namely in FIG. 1 in the operating state with a rolling element 17 turned off and in FIG. 2 in the operating state with an employed rolling element 17. The proposed device is, for. B. can be used for mounting an elevator 01 on a cylinder 02.
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. BezugszeichenlisteFor some applications, e.g. B. with an arrangement of several printing forms in the axial direction side by side on the lateral surface 04 of the forme cylinder 02, it is advantageous to arrange a plurality of supports 11 with at least one rolling element 17 on the cross member 08 in the axial direction, the supports 11 being independent of one another or can be turned on or off in groups by means of actuating means 19 assigned to them on the cylinder 02. For example, a single rolling element 17 or a group of rolling elements 17 can be used selectively for pressing a specific printing form. LIST OF REFERENCE NUMBERS
