Nach der DE 37 31 039 ist eine Vorrichtung zum Befestigen von biegsamen Druckplatten bekannt/ die eine im Zylinderkanalgrund verschiebbar angeordnete Spannleiste aufweist? der schwenkbar eine Klemmleiste zugeordnet ist/ welche durch Kniehebelmechanismen verschwenkt werden kann.According to DE 37 31 039, a device for fastening flexible printing plates is known which has a clamping bar which is arranged so as to be movable in the cylinder channel base and to which a clamping bar is pivotably assigned which can be pivoted by toggle lever mechanisms.
Zum Verbringen der Kniehebelmechanismen in eine Strecklage und damit der Klemmleiste in eine Plattenklemmposition sind Federelemente vorgesehen/ während zum Verbringen der Kniehebelmechanismen aus der Strecklage und damit der Klemmleiste in eine Plattenwechselposition mit einem.Druckmedium beaufschlagbare Stellelemente vorgesehen sind. Zum Spannen der Druckplatte wird die Spannleiste durch sich gegen die Zylinderkanalwand abstützende/ mit einem Druckmedium beaufschlagbarer Stellelemente gegen die Wirkung von Druckfedern und zum Lösen durch die Wirkung der Druckfedern verschoben.Spring elements are provided to move the toggle lever mechanisms into an extended position and thus the clamping bar into a plate clamping position, while adjusting elements that can be acted upon by a pressure medium are provided to move the toggle lever mechanisms from the extended position and thus the clamping bar into a plate changing position. To clamp the pressure plate, the clamping bar is moved against the effect of compression springs by adjusting elements that are supported against the cylinder channel wall and can be acted upon by a pressure medium, and to release it, by the effect of the compression springs.
Diese Vorrichtung ist aufwendig zu realisieren und hat die Nachteile/ daß keine hohen Spannkräfte realisiert werden können und das Druckmedium ständig anliegen muß/ um die Plattenspannung zu gewährleisten.This device is complex to implement and has the disadvantages that high clamping forces cannot be achieved and the pressure medium must be constantly applied in order to ensure the plate tension.
Aufgabe der Erfindung ist es/ eine einfach zu realisierende Vorrichtung zu schaffen/ mit der hohe Spannkräfte realisiert werden können und die auch ohne Anliegen eines Druckmediums eine Plattenspannung sichert.The object of the invention is to create a device that is easy to implement with which high clamping forces can be achieved and which ensures plate tension even without the application of a pressure medium.
Erfindungsgemäß wird die Aufgabe durch die Merkmale des ersten Anspruchs gelöst.According to the invention, the object is achieved by the features of the first claim.
Die Vorteile der erfindungsgemäßen Lösung bestehen darin, daß die Klemmung und Spannung der Druckplatte ohne Zufuhr eines Druckmediums gewährleistet werden kann. Darüber hinaus sind mit einfachen Mitteln hohe Spannkräfte zu realisieren, wobei ein kraftverstärkendes Mittel gleichzeitig zur Arretierung der Spannleiste bei gespannter Druckplatte dient.The advantages of the solution according to the invention are that the clamping and tensioning of the printing plate can be ensured without the supply of a pressure medium. In addition, high clamping forces can be achieved with simple means, whereby a force-enhancing means simultaneously serves to lock the clamping bar when the printing plate is tensioned.
Die Erfindung soll nachstehend an einem Ausführungsbeispiel näher erläutert werden.The invention will be explained in more detail below using an embodiment.
In der zugehörigen Zeichnung ist die Vorrichtung als Schnittdarstellung in der Seitenansicht gezeigt.In the accompanying drawing, the device is shown as a sectional view in side view.
In der Figur ist ein Plattenzylinder 1 mit einem Zylinderkanal 2 dargestellt. Im Zylinderkanal 2 sind eine Plattenklemmeinrichtung 3 zum Klemmen des Plattenanfangs 4 einer Druckplatte 5 und eine Plattenklemm- und -spanneinrichtung 7 zum Klemmen des Plattenendes 6 sowie zum nachfolgenden Spannen der Druckplatte 5 vorgesehen. Die Plattenklemm- und -spanneinrichtung 7 besteht aus einer als einarmiger Hebel ausgebildeten Spannschiene 8/ die mittels einer achsparallelen Welle 9 schwenkbar im Zylinderkanal 2 gelagert ist. Mit der Spannschiene 8 ist schwenkbar durch Lagerbolzen 11 eine als Doppelhebel ausgebildete Klemmschiene 12 verbunden/ die am oberen hakenförmig ausgebildeten Hebelarm mit einer Klemmfläche 12.1 versehen ist/ die mit einer an der Spannschiene 8 versehenen Klemmfläche 8.1 korrespondiert. Am unteren Ende der Klemmschiene 12 greifen vorgespannte Druckfedern 13 an, die sich gegen die Spannschiene 8 abstützen und so die Klemmfläche 12.1 der Klemmschiene 12 gegen die Klemmfläche 8.1 der Spannschiene 8 pressen.The figure shows a plate cylinder 1 with a cylinder channel 2. In the cylinder channel 2, a plate clamping device 3 for clamping the plate beginning 4 of a printing plate 5 and a plate clamping and tensioning device 7 for clamping the plate end 6 and for subsequently tensioning the printing plate 5 are provided. The plate clamping and tensioning device 7 consists of a clamping rail 8 designed as a single-armed lever, which is pivotably mounted in the cylinder channel 2 by means of an axially parallel shaft 9. A clamping rail 12 designed as a double lever is pivotably connected to the clamping rail 8 by bearing bolts 11, which is provided with a clamping surface 12.1 on the upper hook-shaped lever arm, which corresponds to a clamping surface 8.1 provided on the clamping rail 8. Pre-tensioned compression springs 13 engage at the lower end of the clamping rail 12, which are supported against the tensioning rail 8 and thus press the clamping surface 12.1 of the clamping rail 12 against the clamping surface 8.1 of the tensioning rail 8.
In der Zylinderkanalwand 2.1 ist eine Aussparung 14 vorgesehen, in welche das gekröpfte Endstück 13.1 eines Stellkeils 13 eingreift, das sich einerseits gegen in der Aussparung 13 geführte Druckfedern 17 und andererseits gegen ebenfalls in der Ausspa-A recess 14 is provided in the cylinder channel wall 2.1, into which the cranked end piece 13.1 of an adjusting wedge 13 engages, which on the one hand rests against compression springs 17 guided in the recess 13 and on the other hand against compression springs 17 also guided in the recess.
rung 14 angeordnete Stellelemente 18 abstützt.The actuating elements 18 arranged on the support 14 are supported.
Der Stellkeil 13 weist eine zur Spannschiene 8 gerichtete Keilfläche 13.2 auf/ gegen die sich in der Spannschiene 8 angeordnete Stellschrauben 10 stützen/ während der Stellkeil 13 mit der der Keilfläche 13.2 gegenüberliegenden Seite in der Zylinderkanalwand 2.1 vorgesehenen Führungsfläche 19 verschiebbar angeordnet ist. Zwischen der Zylinderkanalwand 2.1 und der Spannschiene 8 sind weiterhin Stellelemente 20 sowie zwischen dem unteren Hebelarm der Klemmschiene 12 und einem zylinderfesten Steg 16 Stellelemente 15 vorgesehen.The adjusting wedge 13 has a wedge surface 13.2 directed towards the clamping rail 8 / against which adjusting screws 10 arranged in the clamping rail 8 rest / while the adjusting wedge 13 is arranged so that it can move with the side opposite the wedge surface 13.2 on the guide surface 19 provided in the cylinder channel wall 2.1. Adjusting elements 20 are also provided between the cylinder channel wall 2.1 and the clamping rail 8, and adjusting elements 15 are provided between the lower lever arm of the clamping rail 12 and a cylinder-fixed web 16.
Die Stellelemente 15/ 18/ 20 sind im Ausführungsbeispiel als mittels eines Druckmediums aufweitbare elastische Schlauchelemente ausgebildet. Bei der Verwendung derartiger Schlauchelemente ist es vorteilhaft/ die Stellelemente 18/ 20 als ein gemeinsames Schlauchelement auszubilden/ welches beim Beaufschlagen mittels eines Druckmediums sowohl in die Wirkungsrichtung des Stellelementes 18 als auch in die Wirkungsrichtung des Stellelementes wirkt.In the exemplary embodiment, the adjusting elements 15/18/20 are designed as elastic hose elements that can be expanded using a pressure medium. When using hose elements of this type, it is advantageous to design the adjusting elements 18/20 as a common hose element, which, when acted upon by a pressure medium, acts both in the direction of action of the adjusting element 18 and in the direction of action of the adjusting element.
Zum Spannen der Druckplatte 5 wird das Plattenende 6, der Plattenanfang 4 ist durch die Plattenklemmeinrichtung 3 fixiert/ zwischen den Klemmflächen 8.1/ 12.1 positioniert und nachfolgend geklemmt. Dazu wird das als Stellelement 15 vorgesehene Schlauchelement mit einem Druckmedium beaufschlagt/ damit die Klemmschiene 12 entgegen der Wirkung der Druckfedern 13 um die Lagerbolzen 11 geschwenkt und so die Klemmfläche 12.1 von der Klemmfläche 8.1 abgehoben. Dabei liegt die Spannschiene 8 mit den Stellschrauben 10 an der Keilfläche 13.2 des Stellkeils 13 an; der durch die Wirkung der Druckfedern 17/ die als gemeinsames Schlauchelement ausgebildeten Stellelemente 18/ 20 sind drucklos/ in seine unterste Position verschoben ist. Nachdem das Plattenende 6 zwischen den Klemmflächen 8.1/ 12.1 positioniert ist/ wird das Stellelement 15 drucklos geschaltet/ damit die Klemmleiste 12 durchTo clamp the pressure plate 5, the plate end 6, the plate beginning 4 is fixed by the plate clamping device 3/ positioned between the clamping surfaces 8.1/ 12.1 and then clamped. To do this, the hose element provided as the adjusting element 15 is subjected to a pressure medium/ so that the clamping rail 12 is pivoted about the bearing bolts 11 against the effect of the compression springs 13 and the clamping surface 12.1 is thus lifted off the clamping surface 8.1. The clamping rail 8 rests with the adjusting screws 10 on the wedge surface 13.2 of the adjusting wedge 13 ; the latter is moved to its lowest position by the effect of the compression springs 17/ the adjusting elements 18/ 20 designed as a common hose element are depressurized. After the plate end 6 is positioned between the clamping surfaces 8.1/ 12.1/ the actuating element 15 is depressurized/ so that the clamping strip 12 can be
die Wirkung der Druckfedern 15 entgegen dem Uhrzeigersinn geschwenkt und so das Plattenende 6 zwischen den Klemmflachen 8.1, 12.1 geklemmt. Anschließend werden die Stellelemente 18, 20 aktiviert/ indem das gemeinsame Schlauchelement mit einem Druckmedium beaufschlagt wird, und damit durch die Wirkung des Stellelements 20 sowie durch die Wirkung des Stellelements 18, durch die Wirkung des Stellelements 18 wird der Stellkeil entgegen der Wirkung der Druckfedern 17 verschoben, die Spannschiene 8 um die Welle 9 im Uhrzeigersinn geschwenkt und damit die Druckplatte gespannt. Da der Neigungswinkel der Keilfläche 13.2 so gewählt ist, daß eine Selbstklemmung auftritt, können nach erfolgter Klemmung die Stellelemente 18, 20 wirkungslos geschaltet werden und damit ein Klemmen und Spannen der Druckplatte 5 ohne Anliegen eines Druckmediums realisiert werden.the effect of the compression springs 15 is pivoted anti-clockwise and thus the plate end 6 is clamped between the clamping surfaces 8.1, 12.1. The adjusting elements 18, 20 are then activated/ by applying a pressure medium to the common hose element, and thus through the effect of the adjusting element 20 and through the effect of the adjusting element 18, through the effect of the adjusting element 18 the adjusting wedge is moved against the effect of the compression springs 17, the tensioning rail 8 is pivoted clockwise around the shaft 9 and thus the pressure plate is clamped. Since the angle of inclination of the wedge surface 13.2 is selected so that self-clamping occurs, the adjusting elements 18, 20 can be switched to ineffective after clamping has taken place and thus clamping and tensioning of the pressure plate 5 can be achieved without the application of a pressure medium.
