Description

Die Erfindung bezieht sich auf einen Plattenzylinder mit einer Plattenbefestigungsvorrichtung, bei der die beiden Enden der Druckplatte auf Auflageflächen aufliegen, die unter einem Winkel von weniger als 45° gegenüber der Tangente an den Zylinderumfang im Schnittpunkt mit der Auflagefläche geneigt sind, die mittels in Aussparungen der Druckplatte eingreifenden Vorsprüngen gegen Verschiebung gesichert sind und die mittels einer Abdeckung auf den Auflageflächen gehalten sind.The invention relates to a plate cylinder with a plate fastening device, in which the two ends of the pressure plate rest on support surfaces which are inclined at an angle of less than 45 ° with respect to the tangent to the cylinder circumference at the point of intersection with the support surface, which means by means of recesses in the Pressure plate engaging projections are secured against displacement and are held on the bearing surfaces by means of a cover.

Ein derartiger aus der-DE-AS 21 33 890 bekannter Plattenzylinder weist eine Abflachung auf, deren beide Randbereiche je eine Auflagefläche für die Endbereiche der Druckplatte bilden. Auf die Abflachung ist eine Abdeckung aufsetzbar, die die auf den Auflageflächen liegenden Endbereiche der Druckplatte gegen Abheben sichert. In der Mitte der Abdeckung ist ein parallel zur Zylinderachse verlaufendes zylindrisches Spannelement angebracht, das auf den einen Endbereich der Druckplatte wirkt. Die Außenfläche der Abdeckung ist gegenüber dem Außenumfang des mit einer Druckplatte belegten Druckzylinders zurückgesetzt.Such a plate cylinder known from DE-AS 21 33 890 has a flattening, the two edge regions of which each form a support surface for the end regions of the printing plate. A cover can be placed on the flattening, which secures the end areas of the pressure plate lying on the support surfaces against lifting off. In the middle of the cover there is a cylindrical clamping element running parallel to the cylinder axis, which acts on one end region of the pressure plate. The outer surface of the cover is set back from the outer circumference of the printing cylinder covered with a printing plate.

Die bekannte Anordnung erfordert einen relativ großen Platzbedarf, der insbesondere durch das Spannelement bedingt ist. Würde ein derartiger Plattenzylinder bei einer Rollendruckmaschine eingesetzt, so ergäben sich größere,nichtdruckende Abschnitte, die zu einem Papierverlust führen. Durch die zurückgesetzte Außenfläche der Abdeckung ergäben sich weiterhin beim Ablauf des Plattenzylinders an benachbarten Zylindern bzw. Walzen unerwünschte Stöße, die zur Beschädigung von Schmitzringen und Lagerungen führen können. Insbesondere bei breiten Plattenzylindern, die zwei oder mehr Platten nebeneinander tragen, werden durch diese Stöße auch Zylinderschwingungen hervorgerufen, die die Druckqualität vermindern. Dies gilt in noch stärkerem Maß für Plattenzylinder, die in Umfangsrichtung zwei oder mehr Druckplatten tragen, da hier während jeder Zylinderumdrehung eine größere Anzahl von Stößen auftritt, die die Zylinderschwingungen anregen.The known arrangement requires a relatively large amount of space, which is due in particular to the tensioning element. If such a plate cylinder were used in a web printing press, this would result in larger, non-printing sections which lead to paper loss. Due to the recessed outer surface of the cover, there would still be undesirable impacts when the plate cylinder ran out on adjacent cylinders or rollers, which could lead to damage of bearer rings and bearings. Particularly in the case of wide plate cylinders that carry two or more plates side by side, these shocks also cause cylinder vibrations, which reduce the print quality. This applies to an even greater extent to plate cylinders which carry two or more pressure plates in the circumferential direction, since here a larger number of impacts occur during each cylinder revolution which excite the cylinder vibrations.

Der Erfindung liegt die Aufgabe zugrunde, einen Plattenzylinder für Rollen-Offsetdruckmaschinen zum Druck von Zeitungen und Zeitschriften mit einer einfach aufgebauten Plattenbefestigungsvorrichtung zu schaffen, bei dem sowohl Stöße, die durch den Ablauf von zurückgesetzten Partien des Zylinders, insbesondere am Gummizylinder entstehen, als auch Papierverluste durch breitere Zylindergruben zur Aufnahme der Plattenbefestigungsmittel vermieden sind.The invention has for its object to provide a plate cylinder for web offset printing machines for printing newspapers and magazines with a simply constructed plate fastening device, in which both impacts caused by the passage of recessed parts of the cylinder, in particular on the blanket cylinder, as well as paper losses are avoided by wider cylinder pits for receiving the plate fasteners.

Erfindungsgemäß wird diese Aufgabe durch Anwendung der im Kennzeichen des Anspruches 1 angegebenen Maßnahmen gelöst.According to the invention, this object is achieved by applying the measures specified in the characterizing part of claim 1.

Weitere Merkmale und Vorteile der Erfindung ergeben sich aus den Unteransprüchen in Verbindung mit der Beschreibung eines Ausführungsbeispieles der Erfindung anhand der Zeichnung. Diese zeigt einen Schnitt durch die Plattenbefestigungsvorrichtung eines Plattenzylinders.Further features and advantages of the invention result from the subclaims in connection with the description of an embodiment of the invention based on the drawing. This shows a section through the plate fastening device of a plate cylinder.

Beim dargestellten Ausführungsbeispiel ist in dem insgesamt mit 1 bezeichneten Plattenzylinder eine insgesamt mit 2 bezeichnete Plattenbefestigungsvorrichtung eingesetzt. Die Plattenbefestigungsvorrichtung 2 weist zwei Auflageflächen 3, 4 auf, die unter einem Winkel α von weniger als 45° gegenüber der Tangente an den Umfang des Plattenzylinders im Schnittpunkt mit der jeweiligen Auflagefläche geneigt angeordnet sind. Die Auflageflächen 3, 4 schließen zwischen sich einen stumpfen Winkel ein, der so groß wie möglich gewählt werden sollte. Aus jeder Auflagefläche 3,4 ragen Vorsprünge 5, 6, beispielsweise Stifte, heraus, die in Aussparungen einer aufgespannten Druckplatte 7 zu deren genauer Lagefixierung eingreifen. Die Breite jeder Auflagefläche zwischen dem Außenumfang des Plattenzylinders 1 und der Berührungslinie mit der zweiten Auflagefläche ist etwa gleich dem Rand des Druckerzeugnisses bemessen. Beim Druck von Zeitungen und Zeitschriften kann daher das von der Rolle ablaufende, zu bedruckende Papier optimal ausgenutzt werden.In the illustrated embodiment, a plate fastening device, generally designated 2, is inserted in the plate cylinder, generally designated 1. The plate fastening device 2 has two contact surfaces 3, 4, which are arranged inclined at an angle α of less than 45 ° with respect to the tangent to the circumference of the plate cylinder at the point of intersection with the respective contact surface. The contact surfaces 3, 4 enclose an obtuse angle between them, which should be chosen as large as possible. Protrusions 5, 6, for example pins, protrude from each support surface 3, 4, which engage in recesses in a clamped pressure plate 7 in order to precisely fix it in position. The width of each contact surface between the outer circumference of the plate cylinder 1 and the line of contact with the second contact surface is approximately equal to the edge of the printed product. When printing newspapers and magazines, the paper to be printed that runs off the roll can therefore be optimally used.

Jeder Auflagefläche 3, 4 ist eine Abdeckleiste 8, 9 zugeordnet, die gemeinsam eine Abdeckung für die Plattenbefestigungsvorrichtung 2 nach außen bilden. Zur Festlegung der Abdeckung am Plattenzylinder 1 weist jede Abdeckleiste 8, 9 Halteansätze 10, 11 auf, die je in einen Schlitz 12, 13 der Befestigungsvorrichtung einschiebbar sind. Die Halteansätze 10, 11 tragen Verzahnungen 14, 15, die in gleichartig ausgebildete Verzahnungen von Druckstücken 16, 17 eingreifen können. Dabei stehen die Druckstücke 16, 17 unter der Wirkung von Druckfedern 18, 19, die sich an festen Teilen der Plattenbefestigungsvorrichtung 2 abstützen und die die Druckstücke 16, 17 gegen die Verzahnungen 14, 15 der Halteansätze 10, 11 drücken. Hiermit können also die Abdeckleisten 8, 9 druckknopfartig am Plattenzylinder 1 festgelegt'werden. Die Erfindung kann jedoch auch mit anderen Haltemitteln für die Abdeckleisten ausgeführt werden, beispielsweise'mit Magneten, die die Abdeckleisten in der gewünschten Stellung halten. Die Abdeckleisten 8, 9 weisen ferner Aussparungen 22, 23 auf, in die bei aufgespannter Druckplatte die Vorsprünge 5, 6 hineinragen.Each support surface 3, 4 is assigned a cover strip 8, 9, which together form a cover for the plate fastening device 2 to the outside. To fix the cover on the plate cylinder 1, each cover strip 8, 9 has retaining lugs 10, 11, each of which can be inserted into a slot 12, 13 of the fastening device. The retaining lugs 10, 11 have toothings 14, 15 which can engage in toothings of pressure pieces 16, 17 of the same design. The pressure pieces 16, 17 are under the action of compression springs 18, 19, which are on fixed parts of the Support plate fastening device 2 and press the pressure pieces 16, 17 against the toothing 14, 15 of the retaining lugs 10, 11. The cover strips 8, 9 can thus be fastened to the plate cylinder 1 in the manner of a push button. However, the invention can also be carried out with other holding means for the cover strips, for example with magnets which hold the cover strips in the desired position. The cover strips 8, 9 also have cutouts 22, 23, into which the projections 5, 6 protrude when the pressure plate is clamped.

Die Außenflächen 20, 21 der Abdeckleisten 8, 9 sind nach einem Krümmungsradius gebogen ausgeführt, der dem Radius der Außenfläche der aufgespannten Druckplatte 7 entspricht. Die Abdeckleisten 8, 9 ergänzen daher den druckfertigen Plattenzylinder zu einem Vollzylinder. Weiterhin weist jede Außenfläche der Abdeckleisten 8, 9 eine wasserannehmende, farbabstoßende Oberfläche auf. Dies kann beispielsweise dadurch erreicht werden, daß die Außenflächen der aus Stahl hergestellten Abdeckleisten 8, 9 gekörnt werden. Durch die Maßnahme wird erreicht, daß beim Ablauf des Zylinders;entlang der Farbauftragwalzen im Bereich der Abdeckleisten 8, 9 keine Farbe angenommen wird, so daß sich saubere Ränder des Druckerzeugnisses ergeben. Durch die Ausgestaltung des mit einer Druckplatte 7 belegten Plattenzylinders 1 als Vollzylinder entfallen weiterhin Vertiefungen in der Außenfläche des Plattenzylinders 1, die beim Ablauf dieses Zylinders beispielsweise am benachbarten Gummizylinder zu Stößen führen, die wiederum ihrerseits gerade bei längeren Plattenzylindern Schwingungen anregen können.The outer surfaces 20, 21 of the cover strips 8, 9 are curved according to a radius of curvature which corresponds to the radius of the outer surface of the clamped pressure plate 7. The cover strips 8, 9 therefore complement the print-ready plate cylinder to a full cylinder. Furthermore, each outer surface of the cover strips 8, 9 has a water-accepting, ink-repellent surface. This can be achieved, for example, by graining the outer surfaces of the cover strips 8, 9 made of steel. The measure ensures that when the cylinder runs along the inking rollers in the area of the cover strips 8, 9, no ink is accepted, so that clean edges of the printed product result. The design of the plate cylinder 1, which is occupied by a pressure plate 7, as a full cylinder further eliminates depressions in the outer surface of the plate cylinder 1, which, when this cylinder expires, leads to impacts, for example, on the adjacent blanket cylinder, which in turn can excite vibrations, particularly in the case of longer plate cylinders.

Für die Erfindung ist es nicht unbedingt erforderlich, daß die Abdeckung aus zwei getrennten Abdeckleisten 8, 9 besteht. Bei Plattenzylindern, die nur mit einer Platte entlang des Umfangs belegt sind, könnten die beiden Abdeckleisten 8, 9 auch zu einem Teil zusammengefaßt sein. Für die Handhabung beim Aufspannen einer Platte ist es jedoch in jedem Fall zweckmäßiger, die Abdeckung zweiteilig auszuführen.It is not absolutely necessary for the invention that the cover consists of two separate cover strips 8, 9 exists. In the case of plate cylinders which are only occupied by one plate along the circumference, the two cover strips 8, 9 could also be combined into one part. For handling when clamping a plate, it is in any case more expedient to carry out the cover in two parts.
