Description

Die Erfindung betrifft eine Vorrichtung zum Befestigen einer biegsamen Druckplatte auf dem Formzylinder einer Druckmaschine mit in Achsrichtung verlaufenden Schlitzen mit parallelen Seitenflächen.The invention relates to a device for fastening a flexible printing plate on the forme cylinder of a printing press with slots running in the axial direction with parallel side surfaces.

Die US 43 04 182 zeigt eine Plattenspannung, bei der die Abkantungen der Druckplatte in einen in Achsrichtung des Formzylinders verlaufenden Schlitz eingeschoben werden. Die Abkantungen sind abgewinkelt und werden zwischen den Seitenflächen des Schlitzes oder zwischen einer Seitenfläche und der an der anderen Seitenfläche anliegenden zweiten Druckplattenabkantung elastisch vorgespannt. Die Spannkraft dient zur reibschlüssigen Sicherung der Plattenabkantungen gegen Herausrutschen. Bei Aluminium- oder Kupferdruckplatten ist jedoch der Elastizitätsmodul nicht ausreichend, um die für eine zuverlässige Sicherung der Platte erforderlichen Federkräfte zu erbringen.US 43 04 182 shows a plate tension in which the folds of the pressure plate are inserted into a slot running in the axial direction of the forme cylinder. The bevels are angled and are elastically pretensioned between the side surfaces of the slot or between one side surface and the second pressure plate fold resting on the other side surface. The clamping force is used to frictionally secure the plate bends against slipping out. In the case of aluminum or copper printing plates, however, the modulus of elasticity is not sufficient to provide the spring forces required for reliably securing the plate.

Die US 19 49 132 zeigt ebenfalls eine Plattenspannung, bei der die Plattenabkantungen in einen in Längsrichtung des Formzylinders verlaufenden Schlitz eingesteckt werden. Hier befindet sich im Spannschlitz eine sich mit Federzungen gegen die Seitenwand des Spannschlitzes abstützende Leiste, die die zunächst erste in den Spannschlitz eingedrückte Abkantung der Druckplatte beim weiteren Spannvorgang sichern soll. Diese Spannvorrichtung ist für eine automatische Plattenbestückung ungeeignet.US 19 49 132 also shows a plate tension in which the plate bends are inserted into a slot running in the longitudinal direction of the forme cylinder. There is a bar in the tensioning slot which is supported with spring tongues against the side wall of the tensioning slot and which is intended to secure the first bend of the pressure plate which is initially pressed into the tensioning slot during the further tensioning process. This clamping device is unsuitable for automatic plate loading.

Der Erfindung liegt die Aufgabe zugrunde, eine Plattenspannung zu schaffen, die mit einfachen Mitteln die Druckplatte zuverlässig spannt und für einen automatischen Plattenwechsel geeignet ist.The invention has for its object to provide a plate tension that reliably clamps the printing plate with simple means and is suitable for an automatic plate change.

Diese Aufgabe wird bei gattungsgemäßen Einrichtungen durch die kennzeichnenden Merkmale des Anspruchs 1 oder 2 gelöst. Der Schlitz bzw. die Schlitze des Formzylinders und die darin befindlichen blattförmigen Federn sind kostengünstig einfach herzustellen. Die Schlitze können dank der schmalen Gestaltbarkeit der Feder sehr eng ausgeführt werden, so daß der schlitzbedingte Verlust an Druckfläche niedrig gehalten werden kann. Die aus Stahl herstellbare Feder bringt im Einbauzustand die erforderliche Federkraft für ihren sicheren Sitz im Zylinderschlitz auf, wobei die Oberfläche des Schlitzes keiner besonderen Rauhigkeitsanforderungen bedarf. Weiterhin liefern die verlängerten Schenkel die nötige, dosierte Spannkraft für die zuverlässige Spannung der Druckplattenabkantungen, wobei die Nachspannung der nachlaufenden Abkantungen ermöglicht wird. Die Druckform schützt bei der ersten Variante außerdem die Feder und den Schlitz vor Schmutz und aggressiven Medien, indem sie diese abdeckt. Schließlich ermöglicht die Vorrichtung einen automatischen Plattenwechsel, beispielsweise mittels eines Roboters.This object is achieved in generic devices by the characterizing features of claim 1 or 2. The slot or slots of the forme cylinder and those located therein Leaf-shaped springs are inexpensive and easy to manufacture. Thanks to the slim design of the spring, the slots can be made very narrow, so that the slot-related loss of pressure area can be kept low. The spring, which can be made of steel, installs the spring force required for its secure fit in the cylinder slot, the surface of the slot not requiring any special roughness requirements. Furthermore, the extended legs provide the necessary, metered clamping force for the reliable clamping of the pressure plate bends, whereby the re-tensioning of the trailing bends is made possible. In the first variant, the printing form also protects the spring and the slot from dirt and aggressive media by covering them. Finally, the device enables an automatic plate change, for example by means of a robot.

Der in Figur 1 dargestellte Formzylinder 1 weist einen in Achsrichtung verlaufenden Schlitz 2 mit parallelen Seitenflächen 3, 4 auf. In den Schlitz 2 sind mehrere, beispielsweise drei, Federn 5 bis in den Grund eingesteckt. Jede Feder weist zwei im eingesteckten Zustand vorgespannte, U-förmige, an den Seitenflächen 3, 4 des Schlitzes 2 anliegende Schenkel 6, 7 auf. Ein Schenkel 6 ist verlängert, enthält eine Grube 8 und endet mit einer Rundung 9. Die Federn 5 sind vorteilhaft aus nichtrostendem Stahl gefertigt, wodurch die Gefahr ihres Festrostens im Schlitz 2 vermindert wird. Weiterhin ist der Formzylinder 1 günstigerweise mit einem galvanischen Üerzug versehen, der technologisch bedingt bis in den Eingangsbereich des Schlitzes 2 hineinreicht und so die für den Druck verlorengehende Kanalbreite verkleinert. Außerdem ist der in den Schlitz 2 hineinreichende galvanische Überzug ein formschlüssiger Schutz der Federn 5 gegen Herausrutschen.The forme cylinder 1 shown in FIG. 1 has an axially extending slot 2 with parallel side surfaces 3, 4. Several, for example three, springs 5 are inserted into the slot 2 right into the base. Each spring has two inserted in it Prestressed, U-shaped legs 6, 7 resting on the side surfaces 3, 4 of the slot 2. One leg 6 is extended, contains a pit 8 and ends with a curve 9. The springs 5 are advantageously made of stainless steel, which reduces the risk of them rusting in the slot 2. Furthermore, the forme cylinder 1 is advantageously provided with a galvanic coating which, for technological reasons, extends into the entrance area of the slot 2 and thus reduces the channel width lost for the pressure. In addition, the galvanic coating extending into the slot 2 is a form-fitting protection of the springs 5 against slipping out.

Zur Montage der Druckplatte 11 werden deren Abkantungen 12, 13 in den Schlitz 2 des Formzylinders 1 eingedrückt. Sie kommen dann zwischen der Seitenfläche 3 und dem verlängerten Schenkel 6 der Federn 5 zu liegen und werden von letzterem gespannt. Vorteilhaft weist die nachlaufende Abkantung 13 der Druckplatte 11 mehrere vorzugsweise kalottenförmige Noppen 14 auf, die mit den Rundungen 9 der Federn 5 zusammenarbeiten (Fig. 4) und eine radiale Zugkraftkomponente auf die nachlaufende Abkantung 13 der Druckplatte 11 erzeugen und so die Plattenspannung verbessern.To assemble the printing plate 11, its bevels 12, 13 are pressed into the slot 2 of the forme cylinder 1. You then come to lie between the side surface 3 and the elongated leg 6 of the springs 5 and are tensioned by the latter. The trailing bend 13 of the pressure plate 11 advantageously has a plurality of preferably dome-shaped knobs 14 which cooperate with the curves 9 of the springs 5 (FIG. 4) and generate a radial tensile force component on the trailing bend 13 of the pressure plate 11 and thus improve the plate tension.

Bei der in Fig. 5 dargestellten weiteren erfindungsgemäßen Vorrichtung weist der Formzylinder 15 zwei in Achsrichtung verlaufende Schlitze 16, 17 mit parallelen Seitenflächen 18, 19 bzw. 20, 21 auf. In jeden Schlitz 16, 17 sind mehrere Federn 22, 23 bis in den Grund eingesteckt. Die Federn 22, 23 ähneln der in Fig. 3 dargestellten Feder. Sie weisen jeweils zwei im eingesteckten Zustand vorgespannte, U-förmige, an den Seitenflächen 18 bis 21 der Schlitze 16, 17 anliegende Schenkel 24 bis 27 auf. Jeweils ein Schenkel 24, 26 ist verlängert und enthält eine Grube 28, 29, die mit einer Rundung 30, 31 abschließt.5, the forme cylinder 15 has two axially extending slots 16, 17 with parallel side surfaces 18, 19 and 20, 21, respectively. A plurality of springs 22, 23 are inserted into the bottom of each slot 16, 17. The springs 22, 23 are similar to the spring shown in FIG. 3. They each have two U-shaped legs 24, 27 that are prestressed in the inserted state and bear against the side surfaces 18 to 21 of the slots 16, 17. Each leg 24, 26 is extended and contains a pit 28, 29, which ends with a curve 30, 31.

Die zu montierende Druckplatte 32 wird zunächst mit ihrer vorlaufenden Abkantung in den Schlitz 17 des Formzylinders 15 eingedrückt. Sie kommt dabei zwischen der Seitenfläche 20 und dem verlängerten Schenkel 26 zu liegen und wird von letzterem gespannt. Anschließend wird die Druckplatte 32 um den Formzylinder 15 gewickelt und die nachlaufende Abkantung 34 in den Schlitz 16 gedrückt. Die Feder 22 weist vorteilhaft eine Leitzunge 35 auf, die die Abkantung 34 zuverlässig zwischen die Seitenfläche 18 und den Schenkel 24 führt. Letzterer spannt dann infolge seiner Vorspannung die nachlaufende Abkantung 34. Das Wickeln der Druckplatte um den Formzylinder und das Eindrücken ihrer nachlaufenden Abkantung kann, ebenso beim vorangegangenen Ausführungsbeispiel, vorteilhaft bei Drehung des Formzylinders unter Anstellung des Übertragungszylinders oder einer anderen Walze an den Formzylinder erfolgen. Auf weitere Ausgestaltungen, die analog dem vorangegangenen Ausführungsbeispiel sein können, wird der Einfachheit halber nicht eingegangen.The pressure plate 32 to be assembled is first pressed into the slot 17 of the forme cylinder 15 with its leading fold. It comes between the side surface 20 and the elongated leg 26 to lie and is stretched by the latter. Then the pressure plate 32 is wound around the forme cylinder 15 and the trailing edge 34 is pressed into the slot 16. The spring 22 advantageously has a guide tongue 35 which reliably guides the fold 34 between the side surface 18 and the leg 24. The latter then tensions the trailing bend 34 as a result of its pretension. The winding of the pressure plate around the forme cylinder and the pressing of its trailing bevel, as in the previous exemplary embodiment, can advantageously take place when the forme cylinder is rotated with the transfer cylinder or another roller on the forme cylinder. For the sake of simplicity, further configurations, which may be analogous to the previous exemplary embodiment, will not be discussed.

In den Ausführungsbeispielen weist der Formzylinder einen Schlitz bzw. ein Schlitzpaar zur Spannung einer Druckplatte auf. Ebenfalls zum Schutzumfang des Patentes gehörig können am Umfang des Formzylinders gleichmäßig verteilt mehrere Schlitze bzw. Schlitzpaare zur Spannung einer entsprechenden Anzahl Druckplatten angeordnet sein.In the exemplary embodiments, the forme cylinder has a slot or a pair of slots for tensioning a printing plate. Also belonging to the scope of protection of the patent, several slots or pairs of slots for tensioning a corresponding number of printing plates can be arranged uniformly distributed on the circumference of the forme cylinder.
