Description

Die Erfindung betrifft eine Vorrichtung zum Aufziehen flexibler Druckformen auf den Formzylinder von Druckmaschinen gemäß dem Oberbegriff von Anspruch 1.The invention relates to a device for mounting flexible Printing forms on the form cylinder of printing machines according to the Preamble of claim 1.

Bei Bogenoffsetdruckmaschinen werden die Druckformen (Druckplatten) auf dem Formzylinder (Plattenzylinder) aufgespannt, indem das dem Druckanfang zugeordnete Ende der Druckform in einer Klemmschiene befestigt wird, woraufhin die Druckform beim Vorwärtsdrehen des Formzylinders auf diesen aufgezogen wird. Daraufhin erfolgt das Einführen der dem Druckende zugewandten Kante der Druckform in eine entsprechende Spannschiene. Um ein sattes Aufbügeln bzw. Aufziehen der Druckform auf den Formzylinderumfang zu gewährleisten, insbesondere bei einer automatisierten Einrichtung zum Druckformwechsel, sind sogenannte Andrückwalzen bekannt geworden, welche sich über die Formatbreite des Formzylinders erstrecken und an diesen an- und von diesem abstellbar gelagert sind (DE 4 218 602 A1).In sheet-fed offset printing machines, the printing forms (printing plates) clamped on the forme cylinder (plate cylinder) by the End of the printing form assigned to the start of printing in a clamping rail is attached, whereupon the printing form when turning the Forme cylinder is mounted on this. Then that happens Inserting the edge of the printing form facing the printing end into a corresponding tensioning rail. For a rich ironing or unwinding to ensure the printing form on the form cylinder circumference, in particular in an automated device for printing form change, So-called pressure rollers have become known, which overlap extend the format width of the forme cylinder and on and on are stored so that it can be set down (DE 4 218 602 A1).

Im Bogenoffsetdruck besteht heute zunehmend ein Trend zur sogenannten Inline-Veredelung. Bei derartig ausgerüsteten Bogenoffsetdruckmaschinen sind dann beispielsweise nach dem letzten Offset-Druckwerk und dem Ausleger ein oder auch mehrere Lackiereinrichtungen angeordnet. Über derartige Lackiereinrichtungen können die Bogen mit transparenten Lacken oder sonstigen fluiden Veredelungsmedien beschichtet werden. Eine Lackiereinrichtung besteht dabei in an sich bekannter Weise aus einem bogenführenden Gegendruckzylinder sowie einen Formzylinder. Die Druckform des Formzylinders bei einer Lackiereinrichtung kann beispielsweise als ein einfaches Gummituch ausgebildet sein (vollflächiges Lackieren). Bei partiellen Lackieren bzw. bei sogenanntem Spot-Lackieren finden als Druckformen auch sogenannte ausgesparte Gummitücher Verwendung. Für besonders aufwendige Lackier- bzw. Veredelungsarbeiten werden als Druckformen spezielle
Lackplatten oder neuerdings auch sogenannte Nyloflex-Platten verwendet, bei denen auf einem Alu-Träger nach Art einer Offsetdruckplatte ein Flexoklischee aufgebracht ist. Die Lackiereinrichtung arbeitet dann nach dem Hochdruck- bzw. Flexodruckverfahren.In sheetfed offset printing there is an increasing trend towards so-called inline finishing. In sheetfed offset printing machines equipped in this way, one or more coating devices are then arranged, for example, after the last offset printing unit and the delivery. The sheets can be coated with transparent lacquers or other fluid finishing media via such lacquering devices. A painting device consists in a manner known per se of a sheet-guiding impression cylinder and a forme cylinder. The printing form of the forme cylinder in a coating device can be designed, for example, as a simple rubber blanket (full-surface coating). In the case of partial painting or so-called spot painting, so-called recessed blankets are also used as printing forms. Special printing forms are used for particularly complex painting or finishing work
Lacquered plates or, more recently, so-called Nyloflex plates, in which a flexo plate is applied to an aluminum support in the manner of an offset printing plate. The painting device then works according to the high-pressure or flexographic printing process.

Um die Rüstzeiten beim Wechseln der Druckformen zu verkürzen, werden heutzutage zunehmend Bogenoffsetdruckwerke mit Einrichtungen zum vollautomatischen oder aber auch halbautomatischen Wechseln der Druckplatten ausgerüstet. Dementsprechend ist man heutzutage auch bestrebt, den Vorgang des Druckformwechsels bei Lackiereinrichtungen zu verautomatisieren. Derartige Einrichtungen (halb- oder vollautomatisches Wechseln der Druckplatten bzw. der Druckformen) bedingen aber einen zusätzlichen bautechnischen Aufwand. Als Beispiel hierzu sei auf die weiter oben beschriebenen Andrückwalzen verwiesen. Diese Andrückwalzen schränken die Zugänglichkeit zu dem Formzylinder ein und müssen dabei ebenfalls hinsichtlich eventueller Gefahrenstellen abgesichert sein.To shorten makeready times when changing printing forms, Nowadays sheetfed offset printing units with facilities are increasingly used for fully automatic or semi-automatic changing of Pressure plates equipped. Accordingly, one is today endeavors to change the printing form in coating equipment to automate. Such facilities (semi or fully automatic Changing the printing plates or printing plates) however, require an additional construction effort. As An example of this is the pressure rollers described above referred. These pressure rollers restrict access to the Form cylinder and must also with regard to possible Hazardous areas must be secured.

Allgemein bekannt sind sogenannte Waschvorrichtungen für die Druckzylinder von Druckmaschinen, insbesondere den Gummituch- oder den Gegendruckzylinder eines Offsetdruckwerkes. Aus der DE 3 614 496 A1 ist dabei eine Waschvorrichtung bekannt, bei der die Waschwalze als eine sogenannte Waschbürste ausgebildet ist. Die Waschvorrichtung ist nebst Waschwalze an den Zylinder an- und abstellbar gelagert. Aus der EP 0 004 605 A1 ist eine weitere Waschvorrichtung für die Zylinder von Druckwerken bekannt, wobei auch hier eine formatbreite Waschwalze mit insbesondere weicher Mantelfläche verwendet wird. Hier ist vorgesehen, durch eine verschwenkbare Lagerung mit der Waschvorrichtung sowohl den Gegendruckzylinder als auch den Gummituchzylinder reinigen zu können.So-called washing devices for the Printing cylinders of printing machines, especially the blanket or the impression cylinder of an offset printing unit. From the DE 3 614 496 A1 discloses a washing device in which the washing roller is designed as a so-called washing brush. The The washing device and the washing roller are attached to the cylinder stored stored. Another is known from EP 0 004 605 A1 Washing device for the cylinders of printing units is known, wherein a format-wide washing roller with a softer one in particular Shell surface is used. Here is provided by a pivotable storage with both the washing device The impression cylinder as well as the blanket cylinder clean too can.

Aufgabe der vorliegenden Erfindung ist es daher, eine Vorrichtung gemäß dem Oberbegriff von Anspruch 1 in bautechnisch einfacher Weise derartig auszugestalten, so daß in Aufziehen flexibler Druckplatten mit einfachen Mitteln möglich ist.The object of the present invention is therefore a device according to the preamble of claim 1 in structurally simpler Way to design such, so that more flexible in winding Printing plates with simple means is possible.

Gelöst wird diese Aufgabe durch die kennzeichnenden Merkmale von Anspruch 1. Weiterbildungen der Erfindung ergeben sich aus den Unteransprüchen.This task is solved by the characteristic features of Claim 1. Further developments of the invention result from the Subclaims.

Nach der Erfindung ist vorgesehen, zum Aufziehen der flexiblen Druckformen auf dem Formzylinder die Waschwalze einer Waschvorrichtung an den Formzylinder anzustellen. Hierbei kann es sich um die Waschwalze einer Waschvorrichtung handeln, die entweder dem Formzylinder direkt zugeordnet ist (Gummituchzylinder einer Lackiereinrichtung) oder um die Waschwalze einer Waschvorrichtung, welche einem mit dem Formzylinder zusammenwirkenden Zylinder zugeordnet ist.According to the invention it is provided to wind up the flexible Printing formes on the forme cylinder the washing roller of a washing device to start on the forme cylinder. This can be the washing roller of a washing device act either the Forme cylinder is directly assigned (blanket cylinder one Painting device) or around the washing roller of a washing device, which is a cylinder interacting with the forme cylinder assigned.

Die erfindungsgemäße Vorrichtung kann nicht nur zum Aufziehen von Druckplatten auf dem Plattenzylinder von Bogenoffsetdruckmaschinen verwendet werden, sondern auch zum insbesondere automatisierten Aufziehen eines Drucktuches auf dem Gummituchzylinder eines Bogenoffsetdruckwerkes und ebenfalls auch zum Aufziehen eines Gummituches oder einer sonstwie gestalteten Druckform auf dem Formzylinder einer Lackiereinrichtung. Nachstehend sind einige Einsatzmöglichkeiten der erfindungsgemäßen Verwendung einer Waschwalze einer Waschvorrichtung zum Aufziehen von flexiblen Druckformen auf dem Form von Druckmaschinen genannt.The device according to the invention can not only be used to wind up Printing plates on the plate cylinder of sheetfed offset presses are used, but also for automated in particular Mount a printing blanket on the blanket cylinder of a sheetfed offset printing unit and also for pulling on a rubber blanket or an otherwise designed printing form on the forme cylinder a painting facility. Below are some uses the use of a washing roller according to the invention a washing device for mounting flexible printing forms called the form of printing machines.

Im Druckwerk einer Bogenoffsetdruckmaschine ist eine dem Gummituchzylinder zugeordnete Waschvorrichtung nahe dem Einlaufspalt zwischen Platten- und Gummituchzylinder (normale Drehrichtung des Druckwerkes) angeordnet. Zum Waschen des Gummituches ist die Waschwalze bzw. die gesamte Waschvorrichtung mit Waschwalze an den Gummituchzylinder an- und abstellbar gelagert. Gerade bei größeren Auflagen wird das Gummituch oftmals mehrmals während des Druckauftrages gewaschen.In the printing unit of a sheetfed offset printing press is one the blanket cylinder assigned washing device near the inlet gap between plate and blanket cylinder (normal direction of rotation of the Arranged). To wash the blanket is the Washing roller or the entire washing device with washing roller to the Blanket cylinder on and off stored. Especially with larger ones The blanket is often placed several times during the print job washed.

Zum Aufziehen einer neuen Druckplatte auf den Plattenzylinder wird nun, nachdem die Vorderkante der Druckplatte auf dem Plattenzylinder befestigt wurde, die Waschwalze an den Außenumfang des Plattenzylinders angestellt, so daS nun die Waschwalze die Funktion einer sonst vorzusehenden Andrückwalze beim Aufziehen der Druckplatte übernimmt. Der Plattenzylinder dreht sich dabei in der gleichen Drehrichtung wie während des Druckens.To pull a new printing plate onto the plate cylinder now after the front edge of the printing plate on the plate cylinder was attached, the washing roller to the outer circumference of the plate cylinder so that the washing roller now functions as a pressure roller to be provided otherwise when pulling on the pressure plate takes over. The plate cylinder rotates in the same Direction of rotation as during printing.

Die oben beschriebene erfindungsgemäße an- und abstellbare Lagerung der Waschwalze der Waschvorrichtung gegenüber dem Plattenzylinder kann insbesondere auch dazu dienen, ein abgekantetes Ende einer Druckplatte in eine entsprechende Spanneinrichtung einzuführen. Entsprechend erfolgt das Anstellen der Waschwalze in einer Winkelstellung des Zylinders, bei welcher das abgekantete Ende der Druckplatte der Waschwalze gegenüberliegt.The storage and storage according to the invention described above the washing roller of the washing device opposite the plate cylinder can also serve, in particular, a beveled end of a Insert the pressure plate into an appropriate clamping device. Correspondingly, the washing roller is set in an angular position of the cylinder where the beveled end of the Pressure plate opposite the washing roller.

Selbstverständlich kann bei einem Bogenoffsetdruckwerk die an den Plattenzylinder an- und abstellbar gelagerte Waschwalze, welche normalerweise zum Reinigen des Gummituches dient, auch zum Aufziehen eines Unterlagebogens auf dem Plattenzylinder dienen. Dies ist insbesondere dann vorteilhaft, wenn der Plattenzylinder eine extra Befestigung für Unterlagebögen aufweist.Of course, in the case of a sheetfed offset printing unit, this can be sent to Washer roller mounted on and off, which normally used to clean the rubber blanket, also for pulling up serve a backing sheet on the plate cylinder. This is particularly advantageous when the plate cylinder has extra attachment for underlay sheets.

Bei einer Lackiereinrichtung, wie sie überwiegend bei Bogenoffsetdruckmaschinen eingesetzt wird, wirkt bekanntlich ein Formzylinder mit einem Gegendruckzylinder zusammen. Hier ist bspw. die Waschvorrichtung mit der Waschwalze ebenfalls im Bereich des einlaufenden Spaltes zwischen Formzylinder und Gegendruckzylinder angeordnet. Die Waschvorrichtung kann durch eine entsprechende verschwenkbare Lagerung nun sowohl dem Reinigen der Zylinderoberfläche des Gegendruckzylinders als auch zum Reinigen eines auf den Formzylinder aufgespannten Gummituchzylinders dienen. Zum Aufziehen eines neuen Gummituches oder einer sonstigen Druckform auf dem Formzylinder wird nun, nachdem die Druckform mit einem Ende am Zylinder befestigt wurde, die Waschwalze bei sich drehendem Zylinder an diesen angestellt. Die Waschwalze übernimmt hier ebenfalls die Funktion einer sonst vorzusehenen Andrückwalze.With a varnishing device, such as those used mainly in sheetfed offset printing machines as is known, a forme cylinder acts together with an impression cylinder. Here is the washing device, for example with the washing roller also in the area of the incoming Gap arranged between the forme cylinder and impression cylinder. The washing device can be pivoted by a corresponding Storage now both cleaning the cylinder surface of the impression cylinder as well as cleaning one on the forme cylinder serve stretched blanket cylinder. To open a new one Blanket or other printing form on the forme cylinder is now attached to the cylinder with one end after the printing form the washing roller was turned on the cylinder while it was rotating. The washing roller also takes on the function of an otherwise pressure roller to be provided.

Bei der erfindungsgemäßen Verwendung einer Waschwalze zum Aufziehen von Druckformen können insbesondere Walzen mit einem weichen Gummi- oder Vliesbezug aber auch Bürsten zum Einsatz kommen. Zum Aufziehen einer Druckform wird dabei der Antrieb der Waschwalze entweder durch eine vorzusehende Kupplung entkuppelt oder sonstwie momentenfrei geschaltet, so daß sich die Waschwalze weitgehend leichtgängig durch die von der Druckform ausgeübte Reibungskraft drehen kann.When using a washing roller for winding according to the invention of printing formes can in particular rollers with a soft rubber or Fleece cover but also brushes are used. To wind up A printing form is used either to drive the washing roller decoupled by a coupling to be provided or otherwise Torque-free, so that the washing roller largely smooth due to the frictional force exerted by the printing form can turn.

Bei bestimmten Druckformen sowie bei einer als Bürste ausgebildeten Waschwalze kann es ferner vorteilhaft sein, die Waschwalze beim Aufziehen der Druckform entgegen der Richtung des Aufziehens anzutreiben, so daß dadurch eine zusätzliche Zugkraft entsteht.With certain printing forms as well as with a brush Washing roller, it may also be advantageous to the washing roller when Winding up the printing form against the direction of winding up to drive, so that this creates an additional pulling force.

Die Verwendung einer Waschwalze zum Aufziehen von Druckformen ist besonders dann vorteilhaft, wenn beispielsweise Nyloflex-Platten mit einer Druckoberfläche nach Art eines Flexoklischees aufgezogen werden sollen. Die Nachgiebigkeit des Bezugs der Waschwalze gibt dabei ein sich Anpassen an die unterschiedliche Dicke der Druckform entsprechend den druckenden und den nichtdruckenden Stellen. Unabhängig von der Sujetverteilung bei einer solchen Druckform ergibt sich dabei ein über die Formatbreite gleichförmiges Andrücken der Druckform an den Formzylinder.The use of a washer roller for mounting printing forms is particularly advantageous if, for example, Nyloflex sheets with a printing surface like a flexo cliché should be. The compliance of the washing roller cover gives thereby adapting to the different thickness of the printing form according to the printing and non-printing points. Regardless of the subject distribution with such a printing form this results in a pressure that is uniform over the width of the format the printing form on the forme cylinder.

Des weiteren erfolgt die Erläuterung von bevorzugten Ausführungsbeispielen der Erfindung anhand der Zeichnungen. Furthermore, preferred exemplary embodiments are explained the invention with reference to the drawings.

Diese besteht aus einem Formzylinder 1, der mit einem den bogenführenden Gegendruckzylinder 8 zusammenwirkt. Die Drehrichtung der Zylinder ist durch die Pfeile angedeutet. In der einlaufenden Seite zwischen Formzylinder 1 und Gegendruckzylinder 8 ist (vergl. Figur 1 bis 3) um eine Schwenkachse 6 verkippbar gelagert eine Waschvorrichtung 3 mit Waschwalze 4 angeordnet. Fig. 4 zeigt dabei die Ruheposition der Waschvorrichtungen 3, d.h. die Waschwalze 4 liegt weder am Formzylinder 1 noch am Gegendruckzylinder 8 an.4 to 6 show the structure of a known Varnishing device such as this used in sheet-fed offset printing machines Find. This consists of a forme cylinder 1, which with a sheet-guiding impression cylinder 8 cooperates. The direction of rotation the cylinder is indicated by the arrows. In the incoming Side between forme cylinder 1 and impression cylinder 8 is (see. Figure 1 to 3) mounted tiltable about a pivot axis 6 Washing device 3 with washing roller 4 arranged. Fig. 4 shows the rest position of the washing devices 3, i.e. the washing roller 4 is neither on the forme cylinder 1 nor on the impression cylinder 8.

Durch Betätigen des Schwenkantriebs 7 wird die Waschvorrichtung 3 mit der Waschwalze 4 an den Gegendruckzylinder 8 angestellt, so daß ein Reinigen der bogentragenden Oberfläche stattfinden kann. Dies dient dem Entfernen von Farbresten, insbesondere bei Schön- und Widerdruck, sowie dem Entfernen von Papierstaub (Fig. 5). Wird die Waschvorrichtung 3 aus der Position gemäß Fig. 4 entgegen dem Uhrzeigersinn verschwenkt (nicht dargestellt), so dient sie dem Reinigen eines um den Formzylinder 1 gespannten Gummituches. Soll ein Gummituch oder eine Lackplatte auf den Formzylinder aufgespannt werden, so erfolgt ebenfalls ein Anstellen der Waschwalze 4 an den Formzylinder 1.By actuating the swivel drive 7, the washing device 3 with the washing roller 4 on the impression cylinder 8, so that cleaning of the sheet-bearing surface can take place. This is used to remove paint residues, especially for fine and Back pressure, as well as the removal of paper dust (Fig. 5). Will the Washing device 3 from the position shown in FIG. 4 against the Pivoted clockwise (not shown), it serves the Clean a rubber blanket stretched around the forme cylinder 1. Should a rubber blanket or a varnish plate clamped on the forme cylinder are, the washing roller 4 is also turned on Forme cylinder 1.

Fig. 6 zeigt eine Waschvorrichtung 3 mit an den Formzylinder 1 angestellter Waschwalze 4. Auch hier erfolgt das Anstellen der Waschwalze 4 bzw. der gesamten Waschvorrichtung 3 an den Formzylinder 1, nachdem eine Druckform 5 an einer entsprechenden Befestigungsvorrichtung des Formzylinders 1 angebracht wurde. Die Waschvorrichtung 3 ist durch nicht dargestellte Gelenke (z. B. Geradführungen) bzgl. dem Formzylinder 1 verfahrbar. Während des Aufziehvorganges der Druckform 5 auf den Formzylinder 1 durch entsprechendes Drehen des Formzylinders 1 bleibt die Waschwalze 4 angestellt.6 shows a washing device 3 with the forme cylinder 1 employed washing roller 4. Here too the Washing roller 4 or the entire washing device 3 on the forme cylinder 1 after a printing form 5 on a corresponding fastening device of the forme cylinder 1 was attached. The washing device 3 is characterized by joints (not shown) (e.g. Straight guides) with respect to the forme cylinder 1. During the Pulling the printing form 5 onto the plate cylinder 1 through the washing drum 4 remains correspondingly rotating the forme cylinder 1 employed.

Bei den Druckformen 5 auf dem Formzylinder 1 kann es sich um vollflächige oder ausgesparte Gummitücher bzw. um Druckbildträger nach Art von Flexoklischees handeln. Ferner kann die erfindungsgemäße Waschwalze 4 auch dazu dienen, auf dem Formzylinder 1 anzubringende Unterlagebögen aufzuziehen. Dies ist besonders dann vorteilhaft, wenn der Unterlagebogen mit eigenen Befestigungsvorrichtungen am Formzylinder 1 vor dem Aufbringen der Druckform 5 zu montieren ist. The printing forms 5 on the forme cylinder 1 can be full-surface or recessed blankets or around printed image carriers act in the manner of flexo clichés. Furthermore, the Washing roller 4 according to the invention also serve on the forme cylinder 1 paper sheets to be attached. This is especially then advantageous if the underlay sheet with its own fastening devices on the forme cylinder 1 before applying the printing form 5 is to be assembled.
