Fig. 3 zeigt die vorliegende Erfindung während eines anfänglichen Klemmvorgangs vor dem Aufbringen der Druckplatte 13 auf einen Plattenzylinder 11, der während des Stillstandes der nicht gezeigten Druckmaschine vorzugsweise fliegend in einer Seitenwand derselben gelagert ist. Die Platte 13, die ursprünglich flach ist, besitzt Enden 14, 15, die um ca. 90° abgewinkelt oder abgebogen sind. Die Platte 13 wird in eine im wesentlichen zylindrische Form gebracht, wobei die abgebogenen Enden 14, 15 nebeneinander und in etwa parallel zueinander verlaufen und sich somit ein schmaler Spalt 19 entlang der Länge der zylindrisch geformten Platte 13 erstreckt. Um die Platte 13 vorübergehend in der zylindrischen Form zu halten, können die Enden 14, 15 mittels einer beliebigen bekannten Technik, wie z.B. durch Kleben, Punktschweißen oder durch eine Lochverbindung, bei der ein Loch durch beide Enden (14, 15) in der Weise gestanzt wird, daß das Material des einen in das Loch des anderen Endes eingreift, miteinander verbunden werden.3 shows the present invention during an initial clamping operation the application of the printing plate 13 to a plate cylinder 11, which during the Standstill of the printing machine, not shown, preferably flying in one Side wall of the same is stored. The plate 13, which is originally flat, has Ends 14, 15 which are angled or bent by approximately 90 °. The plate 13 is in brought into a substantially cylindrical shape, the bent ends 14, 15th run side by side and approximately parallel to each other and thus become narrower Gap 19 extends along the length of the cylindrically shaped plate 13. To the To temporarily hold plate 13 in the cylindrical shape, the ends 14, 15 using any known technique, e.g. by gluing, spot welding or by a hole connection, in which a hole through both ends (14, 15) in the Is punched in such a way that the material of the one engages in the hole of the other end, be connected to each other.

Für den Klemmechanismus 18 ist ein Ständer 20 vorgesehen, auf welchem dieser während eines Klemmvorgangs vorübergehend freischwebend montiert ist. Die Enden 14, 15 der zylinderförmigen Platte 13 werden in einen axialen Schlitz des Klemmechanismus 18 eingefügt. Wie im folgenden im Detail beschrieben ist, wird der Klemmechanismus 18 geschlossen, nachdem die Plattenenden 14, 15 in den axialen Schlitz 12 des Klemmechanismus 18 eingefügt sind, so daß die zylinderförmige Platte 13 im Klemmechanismus 18 befestigt ist. Da der Klemmechanismus 18 die Plattenenden 14, 15 fest zusammendrückt, verengt sich der entlang der Länge der zylinderförmigen Platte 13 verlaufende Spalt 19, so daß die Platte 13 in ihrer zylindrischen Form fixiert ist.For the clamping mechanism 18, a stand 20 is provided, on which this is temporarily suspended freely during a clamping process. The Ends 14, 15 of the cylindrical plate 13 are in an axial slot of the Clamping mechanism 18 inserted. As described in detail below, the Clamping mechanism 18 closed after the plate ends 14, 15 in the axial Slot 12 of the clamping mechanism 18 are inserted so that the cylindrical plate 13th is fixed in the clamping mechanism 18. Since the clamping mechanism 18 the Plate ends 14, 15 compresses tightly, which narrows along the length of the cylindrical plate 13 extending gap 19 so that the plate 13 in its cylindrical shape is fixed.

Nach dem Befestigen der Platte 13 durch den Klemmechanismus 18, werden die Platte 13 und der Klemmechanismus 18 vom Klemmechanismus-Ständer 20 entfernt und auf dem Plattenzylinder 11 angebracht. Die Fig. 4 und 5 zeigen diesen Vorgang des Anbringens der Platte 13 auf dem Plattenzylinder 11. Im Plattenzylinder 11 befindet sich ein axialer Schlitz 21, der sich vorzugsweise über die gesamte Zylinderbreite hinweg erstreckt und der eine Breite und Tiefe aufweist, die das Einfügen des Klemmechanismus 18 problemlos ermöglicht. Auf der Außenfläche des Plattenzylinders 11 befinden sich eine Reihe von Druckluftöffnungen 22, welche mit radialen Druckluft-Zutuhrkanälen 23 verbunden sind, die wiederum mit einem zentralen axialen Druckluft-Zufuhrkanal 24 verbunden sind. Der Plattenzylinder 11 ist mit seinem einen Ende 27 in einer sich in einer Seitenwand 26 des Maschinenrahmens befindlichen Lagerung 25 gelagert. Das andere Ende 28 des Plattenzylinders 11 ist lösbar in einer nicht gezeigten Lagerung gelagert; diese Lagerung kann beim Aufbringen und Entfernen der Platte 13 vom Plattenzylinder 11 weggeschwenkt werden. Die Art und Weise, in welcher das Ende 28 des Plattenzylinders 11 lösbar gelagert ist, ist im Stand der Technik bekannt.After the plate 13 is fastened by the clamping mechanism 18, the plate 13 and the clamping mechanism 18 removed from the clamping mechanism stand 20 and on the Plate cylinder 11 attached. Figures 4 and 5 show this process of attachment the plate 13 on the plate cylinder 11. In the plate cylinder 11 there is an axial Slot 21, which preferably extends over the entire width of the cylinder and which has a width and depth that the insertion of the clamping mechanism 18th easily possible. On the outer surface of the plate cylinder 11 there are one Row of compressed air openings 22, which with radial compressed air supply channels 23rd are connected, which in turn are connected to a central axial compressed air supply channel 24 are connected. The plate cylinder 11 is in one with its one end 27 a bearing 25 located on a side wall 26 of the machine frame. The other end 28 of the plate cylinder 11 is detachable in a storage, not shown stored; this storage can when applying and removing the plate 13 from Plate cylinder 11 are pivoted away. The way in which the end 28 of the plate cylinder 11 is releasably mounted is known in the prior art.

Zum Aufbringen der Platte 13 auf den Plattenzylinder 11 wird durch die Luftzufuhrkanäle 23, 24 Druckluft zugeführt, die dann aus den Öffnungen 22 strömt. Ein Ende 29 der Kombination von Platte 13 und Klemmechanismus 18 wird in Montagerichtung, d.h. in Richtung des Endes 28 des Plattenzylinders 11 bewegt, so daß der Klemmechanismus 18, nachdem er in den axialen Schlitz 21 eingeführt worden ist, entlang des Schlitzes 21 gleitet. Die aus den Öffnungen 22 strömende Druckluft bewirkt ein leichtes Dehnen des Innendurchmessers der Platte 13, so daß während des Gleitens der Platte 13 über den Plattenzylinder 11 ein Freiraum zwischen dem Innendurchmesser der Platte 13 und dem Außendurchmesser des Plattenzylinders 11 entsteht. Anders ausgedrückt bildet die aus den Öffnungen 23 strömende Druckluft ein Luftkissen, über das die Platte 13 gleitet. Der Klemmechanismus 18 wird entlang des axialen Schlitzes 21 bewegt, bis die Platte 13 den Plattenzylinder 11 vollständig bedeckt. Danach wird die Druckluftzufuhr im Kanal 24 gestoppt, was die Platte 13 auf der Mantelfläche des Plattenzylinders 11 geringfügig schrumpfen läßt. Im Anschluß daran wird das während des Aufschiebevorgangs freie Ende 28 des Plattenzylinders 11 in der nicht gezeigten abschwenkbaren Lagerung gelagert, und die Maschine ist betriebsbereit.To apply the plate 13 to the plate cylinder 11 is by the Air supply channels 23, 24 are supplied with compressed air, which then flows out of the openings 22. On End 29 of the combination of plate 13 and clamping mechanism 18 is in Installation direction, i.e. moved towards the end 28 of the plate cylinder 11 so that the clamping mechanism 18 after it has been inserted into the axial slot 21, slides along the slot 21. The compressed air flowing out of the openings 22 causes a slight stretching of the inner diameter of the plate 13 so that during sliding the plate 13 via the plate cylinder 11, a space between the inner diameter the plate 13 and the outer diameter of the plate cylinder 11 is formed. Different expressed, the compressed air flowing out of the openings 23 forms an air cushion, via that slides the plate 13. The clamping mechanism 18 is along the axial slot 21 moves until the plate 13 completely covers the plate cylinder 11. After that the Compressed air supply in the channel 24 stopped, causing the plate 13 on the outer surface of the Plate cylinder 11 can shrink slightly. After that it will be during of the slide-open operation free end 28 of the plate cylinder 11 in that not shown hinged storage is stored, and the machine is ready for use.

Fig. 15 zeigt eine weitere alternative Ausführung mit einem Klemmechanismus 18, der eine nach außen hin konisch oder geneigt geformte Seitenwand 67 und eine im wesentlichen radial verlaufende Seitenwand 68 umfaßt.15 shows a further alternative embodiment with a clamping mechanism 18 which an outwardly conical or inclined shaped side wall 67 and one in essentially radially extending side wall 68.

Die Fig. 16 und 17 zeigen weitere Ausführungsbeispiele des Klemmechanismus 18 der vorliegenden Erfindung, die den Ausführungsbeispielen der Fig. 7 und 7a gleichen, da sie Klemmbacken 35', 36' umfassen, die sich relativ zueinander bewegen und die Enden 14, 15 der Druckplatte 13 zusammenklemmen. Es ist eine Feder 38', die eine zwischen den Klemmbacken 35', 36' montierte Spiralfeder sein kann, vorgesehen, um die Klemmbacken 35', 36' gegeneinander vorzuspannen, derart, daß sich diese aufeinander zubewegen. Die Klemmbacken weisen Spreizlöcher 39' auf, in welche beim Einführen der Enden 14, 15 der Druckplatte 13 in den axialen Schlitz 12 ein nicht gezeigter U-förmiger Spreizstift eingefügt wird. Nach dem Einführen der Plattenenden 14, 15 in den axialen Schlitz 12 des Klemmechanismus 18 außerhalb des Plattenzylinders 11 wird der Spreizstift wieder aus den Spreizlöchern 39' entfernt, und durch die Vorspannung der Feder 38' werden die Klemmbacken 35', 36'an die Plattenenden 14, 15 und gegeneinander gedrückt, so daß die Platte 13 mit ihren Enden 14, 15 zwischen den Klemmbacken 35', 36' eingeklemmt ist. Danach wird der Klemmechanismus 18 in den axialen Schlitz des Plattenzylinders 11 eingeführt. Die Klemmbacken 35', 36' weisen Seitenwände auf, die zur Mitte des Zylinders 11 hin geneigt oder konisch auseinanderlaufend geformt sind. Zwischen den Klemmbacken 35', 36' ist ein Sicherungsmechanismus angebracht, der einen Kurvenmechanismus 69 umfaßt. Nachdem der Klemmechanismus 18 in den axialen Schlitz eingefügt ist, wird der Kurvenmechanismus 69 in eine Sicherungsposition gedreht. Diese Bewegung des Kurvenmechanismus bewirkt ein leichtes Auseinanderspreizen der Klemmbacken 35', 36', wobei die konischen Seiten der Klemmbacken 35', 36' gegen die korrespondierenden Seitenwände des axialen Schlitzes des Plattenzylinders 11 gedrückt werden und somit der Klemmechanismus 18 im Schlitz gesichert ist. Fig. 17 zeigt eine alternative Ausführungsform eines erfindungsgemäßen Sicherungsmechanismus, welcher im wesentlichen mit der in Fig. 16 dargestellten Ausführungsform übereinstimmt, bei der jedoch das Aufspreizen der Klemmbacken 35', 36' mit Hilfe eines Drehmechanismus 70 sowie einer sich in zugehörige Bohrungen der Klemmbacken 35', 36' hinein erstreckenden lateralen Schraube 71 erfolgt. Der Drehmechanismus 70 kann beispielsweise mit Hilfe eines Imbus-Schlüssels über einen am Drehmechanismus 70 geformten Innen-Sechskantkopf im Klemmechanismus 18 verdrehbar sein, und besitzt einen in Fig. 17 nicht näher dargestellten schneckenförmigen Gewindeabschnitt, welcher in Höhe der lateralen Schraube 71 angeordnet ist. Die laterale Schraube 71 weist einen ersten Gewindeabschnitt in Form eines Rechtsgewindes auf, welcher z. B. in eine zugehörige Gewindebohrung in der ersten Klemmbacke 35' eingeschraubt ist; und weist am gegenüberliegenden Ende einen Gewindeabschnitt mit entgegengesetzter Steigung - in diesem Falle ein Linksgewinde - auf, welcher in eine entsprechende zugehörige Linksgewindebohrung in der gegenüberliegenden Klemmbacke 36'eingeschraubt ist. Zwischen den beiden Gewindeabschnitten entgegengesetzter Steigung weist die laterale Schraube 71 einen in Fig. 17 durch horizontal verlaufende Striche angedeuteten zahnradförmigen Abschnitt auf, der mit dem schneckenförmigen Abschnitt des Drehmechanismus 70 zusammenwirkt, und über den je nach Drehrichtung des Drehmechanismus 70 die laterale Schraube 71 in die eine oder in die andere Richtung rotiert wird und dadurch die Klemmbacken 35', 36' auseinanderspreizt bzw. zusammenzieht. Nachdem der Klemmechanismus 18 von Fig. 17 in den axialen Schlitz des Plattenzylinders 11 eingeführt wurde, kann dieser beispielsweise im axialen Schlitz dadurch gesichert werden, daß die Klemmbacken 35', 36' durch entsprechendes Verdrehen des Drehmechanismus 70 geringfügig auseinandergespreizt werden und der Klemmechanismus 18 aufgrund der geneigt verlaufenden oder konisch ausgebildeten Seitenwände der Klemmbacken 35', 36' im axialen Schlitz des Plattenzylinders 11 verspannt und gesichert wird. 16 and 17 show further embodiments of the clamping mechanism 18 of the present invention, the same as the embodiments of FIGS. 7 and 7a, because they comprise jaws 35 ', 36' which move relative to each other and which Clamp ends 14, 15 of pressure plate 13 together. It is a spring 38 ', the one between the jaws 35 ', 36' mounted coil spring may be provided to to bias the jaws 35 ', 36' against each other such that they move towards each other. The jaws have expansion holes 39 ', in which at Inserting the ends 14, 15 of the pressure plate 13 into the axial slot 12 is not shown U-shaped spreader pin is inserted. After introducing the Plate ends 14, 15 in the axial slot 12 of the clamping mechanism 18 outside of Plate cylinder 11, the expansion pin is removed from the expansion holes 39 ', and by the bias of the spring 38 'the jaws 35', 36 'to the Plate ends 14, 15 and pressed against each other, so that the plate 13 with their Ends 14, 15 is clamped between the jaws 35 ', 36'. Then the Clamping mechanism 18 inserted into the axial slot of the plate cylinder 11. The Clamping jaws 35 ', 36' have side walls which point towards the center of the cylinder 11 are inclined or tapered apart. Between the jaws 35 ', 36 'a safety mechanism is attached which has a cam mechanism 69 includes. After the clamping mechanism 18 is inserted into the axial slot, the Cam mechanism 69 rotated to a securing position. This movement of the Curve mechanism causes the jaws 35 'to spread apart slightly, 36 ', the conical sides of the jaws 35', 36 'against the corresponding side walls of the axial slot of the plate cylinder 11 pressed are and thus the clamping mechanism 18 is secured in the slot. 17 shows one alternative embodiment of a security mechanism according to the invention, which essentially coincides with the embodiment shown in FIG. 16, in which however, the spreading of the jaws 35 ', 36' by means of a rotating mechanism 70 and one in associated bores of the jaws 35 ', 36' extending lateral screw 71 takes place. The rotating mechanism 70 can for example with the help of an Allen key via one on the rotating mechanism 70 Shaped inner hexagon head in the clamping mechanism 18 can be rotated, and has a helical thread section, not shown in FIG. 17, which is arranged at the level of the lateral screw 71. The lateral screw 71 has one first thread section in the form of a right-hand thread, which z. B. in a associated threaded hole is screwed into the first jaw 35 '; and points at the opposite end a thread section with opposite pitch - in in this case a left-hand thread - which fits into a corresponding associated Left-hand threaded hole is screwed into the opposite jaw 36 '. Between the two threaded sections of opposite pitch, the lateral has Screw 71 is indicated by horizontal lines in FIG. 17 gear-shaped section on which with the helical section of the Rotating mechanism 70 cooperates, and depending on the direction of rotation of the Rotation mechanism 70 the lateral screw 71 in one or the other direction is rotated and thereby the jaws 35 ', 36' spread apart or contracts. After the clamping mechanism 18 of Fig. 17 into the axial slot of the plate cylinder 11 was introduced, this can for example in the axial slot be secured in that the jaws 35 ', 36' by appropriate Rotation of the rotary mechanism 70 are slightly spread apart and the Clamping mechanism 18 due to the inclined or conical shape Side walls of the clamping jaws 35 ', 36' in the axial slot of the plate cylinder 11 is tensioned and secured.
