Ein Plattenzylinder 1 einer Rotationsdruckmaschine weist eine linke und rechte Einhängenase 2, 3 auf, die jeweils von Außen- und Innenfläche 4, 6, 7, 8 gebildet werden. Die jeweilige Außenfläche 4, 6 schließt mit der Innenfläche 7, 8 einen spitzwinkligen Öffnungswinkel Alpha von beispielsweise 45° ein und ist an eine Krümmung einer Kontur 9 des Plattenzylinders 1 angepaßt. A plate cylinder 1 of a rotary printing machine has a left and right hooking nose 2, 3, respectively of outer and inner surface 4, 6, 7, 8 are formed. The respective outer surface 4, 6 closes with the Inner surface 7, 8 has an acute-angled opening angle Alpha of, for example, 45 ° and is at one Curvature of a contour 9 of the plate cylinder 1 adapted.

Diese Einhängenasen 2, 3 verlaufen parallel zu einer Drehachse 5 des Plattenzylinders 1 und werden an ihrer Außenfläche 4, 6 von der Kontur 9 des Plattenzylinders 1 begrenzt. Unterhalb der beiden Einhängenasen 2, 3 verläuft ein Kanal 11 axial mit beispielsweise U-förmigen Querschnitt. In diesem Kanal 11 ist eine Dichtung 12, z. B. eine Rundschnur, eingelegt. Eine Druckplatte 13 oder eine Trägerplatte eines Gummituches ist mit ihren abgekanteten Enden 14, 16 in die Einhängenasen 2, 3 eingehängt. Abgekantete Schenkel 17, 18 dieser Enden schließen mit der Druckplatte ebenfalls einen Öffnungswinkel Alpha von beispielsweise 45° ein, der auf die Einhängenasen 2, 3 angepaßt ist. Die linke Einhängenase 2 ist direkt in den Plattenzylinder 1 eingeformt, während die rechte Einhängenase 3 schwenkbar beispielsweise an einer Spannspindel 19 angeordnet ist. Es ist auch möglich beide Einhängenasen 2, 3 schwenkbar auszuführen. In einem Spannendzustand setzt die Spannspindel 19 mit der Einhängenase 3 die Kontur 9 des Plattenzylinders 1 absatzlos, kontinuierlich fort.These hook-in lugs 2, 3 run parallel to one Axis of rotation 5 of the plate cylinder 1 and are on it Outer surface 4, 6 of the contour 9 of the plate cylinder 1 limited. Below the two hook-in lugs 2, 3 a channel 11 runs axially with, for example U-shaped cross section. In this channel 11 is one Seal 12, e.g. B. a round cord inserted. A printing plate 13 or a carrier plate Blanket is with its folded ends 14, 16 in the hook-in lugs 2, 3 hooked in. Folded legs 17, 18 of these ends close with the pressure plate also an opening angle alpha of, for example 45 °, which is adapted to the hanging lugs 2, 3. The left hooking lug 2 is directly in the Plate cylinder 1 molded while the right one Hanging nose 3 pivotable, for example, on one Clamping spindle 19 is arranged. It is also possible Execute both hook-in lugs 2, 3 pivotably. In a clamping state sets the clamping spindle 19 with the Attach the nose 3 to the contour 9 of the plate cylinder 1 continuously, continuously.

An die Außenfläche 6 der Einhängenase 3 schließt sich in Richtung Inneres 21 des Plattenzylinders 1 eine Fläche 22 an, die mit der Außenfläche 6 einen Öffnungswinkel Beta, z. B. Beta = 150°, einschließt. Eine auf diese Fläche 22 angepaßte Abstützfläche 23 ist an dem Plattenzylinder 1 in Richtung seines Inneren 21 angeformt. Dieser Fläche 22 annähernd gegenüberliegend ist an einer Unterseite einer Spitze der Einhängenase 3 eine Auflagefläche 24 angeordnet, für die ebenfalls eine an dem Inneren 21 des Plattenzylinders 1 direkt angeformte Abstützfläche 26 vorgesehen ist. Die beiden Abstützflächen 23, 26 verlaufen nicht parallel und schließen vorzugsweise einen Winkel Delta von 15° bis 30° ein, d. h. die beiden Abstützflächen 23, 26 sind nach außen verjüngend zueinander angeordnet. Die Spannspindel 19 ist in einer Zylindergrube 27 in einer gehärteten, schalenförmig ausgebildeten Formmasse 28 schwenkbar um ihre Drehachse 20 gelagert. Die Schwenkbewegung zum Spannen und Entspannen der Druckplatte 13 wird mittels eines an einem stirnseitigen Ende der Spannspindel 19 angeordneten Schneckengetriebes 29 erzeugt. Dieses selbsthemmende Schneckengetriebe 29 besteht im wesentlichen aus einem Zahnsegment 31, einer ersten Schnecke 32, einem Schneckenrad 33 und einer zweiten Schnecke 34. Die erste Schnecke 32 ist gemeinsam mit dem Schneckenrad 33 auf einer drehbar gelagerten Welle 36 befestigt. Diese Welle 36 ist rechtwinklig zur Spannspindel 19 an einer Stirnseite des Plattenzylinders 1 in zwei Lagerungen 37, 38 angeordnet. Die Schnecke 32 dieser Welle 36 greift in das stirnseitig befestigte Zahnsegment 31 der Spannspindel 19 ein, während das Schneckenrad 33 mit der zweiten Schnecke 34 kämmt. Die zweite Schnecke 34 ist im vorliegenden Ausführungsbeispiel mit einem Sechskant 39 zur Einleitung einer Drehbewegung versehen, aber es sind auch andere Stellantriebe, z. B. Schrittmotoren, möglich. Anstelle des Schneckengetriebes 29 sind auch andere Antriebe zur Erzeugung der Schwenkbewegung möglich.On the outer surface 6 of the hooking nose 3 closes in A surface in the direction of the interior 21 of the plate cylinder 1 22 on, with the outer surface 6 an opening angle Beta, e.g. B. Beta = 150 °. One on this Surface 22 adapted support surface 23 is on the Plate cylinder 1 in the direction of its interior 21 molded. This surface 22 approximately opposite is on the underside of a tip of the hooking nose 3 a support surface 24 is arranged, for which also a on the interior 21 of the plate cylinder 1 directly molded support surface 26 is provided. The two Support surfaces 23, 26 are not parallel and preferably close an angle delta of 15 ° to 30 ° on, d. H. the two support surfaces 23, 26 are arranged tapering towards each other. The Clamping spindle 19 is in a cylinder pit 27 in one hardened, shell-shaped molding compound 28 pivoted about its axis of rotation 20. The Swiveling movement for tensioning and relaxing the Pressure plate 13 is by means of a front End of the clamping spindle 19 arranged worm gear 29 generated. This self-locking worm gear 29 consists essentially of a toothed segment 31, one first worm 32, a worm wheel 33 and one second screw 34. The first screw 32 is common with the worm wheel 33 on a rotatably mounted Shaft 36 attached. This shaft 36 is perpendicular to Clamping spindle 19 on one end of the plate cylinder 1 arranged in two bearings 37, 38. The snail 32 this shaft 36 engages in the face fastened Tooth segment 31 of the clamping spindle 19, while the Worm gear 33 meshes with the second worm 34. The second screw 34 is present Embodiment with a hexagon 39 for Initiate a rotary motion, but there are other actuators, e.g. B. stepper motors, possible. Instead of the worm gear 29 are also other drives for generating the swivel movement possible.

Die Funktionsweise der erfindungsgemäßen Vorrichtung ist folgendermaßen:
Die Druckplatte 13 wird mit ihrem abgekanteten Ende 14 zuerst in die feststehende Einhängenase 2 am Druckanfang und z. B. nach einer Umdrehung mit ihrem Ende 16 in die geöffnete, d. h. nach außen geschwenkte Einhängenase 3 am Druckende eingehängt. Es ist aber auch möglich die feststehende Einhängenase 2 am Druckende und die schwenkbare Einhängenase 3 am Druckanfang anzuordnen und somit auch eine Drehrichtungsumkehr des Plattenzylinders 1 zu ermöglichen.The operation of the device according to the invention is as follows:
The pressure plate 13 is first with its folded end 14 in the fixed hanging lug 2 at the beginning of the print and z. B. after one revolution with its end 16 hooked into the open, that is to say pivoted outward hooking nose 3 at the end of the print. However, it is also possible to arrange the fixed hook-in lug 2 at the end of the print and the pivotable hook-in lug 3 at the start of the print and thus also enable the direction of rotation of the plate cylinder 1 to be reversed.

Mittel eines an dem Sechskant 39 angreifenden Werkzeuges wird nun an der zweiten Schnecke 34 gedreht, so daß diese Drehbewegung auf die Welle 36 und schließlich auf das Zahnsegment 31 übertragen wird. Dadurch schwenkt die Spannspindel 19 um ihre Drehachse 20 mit der Einhängenase 3 in Richtung Inneres 21 des Plattenzylinders 1 und spannt die Druckplatte 13. Nachdem der Spannendzustand nahezu erreicht ist, liegt die Auflagefläche 24 der Einhängenase 3 auf der Abstützfläche 26 auf. Über diese Stellung hinaus wird nun mittels des Schneckengetriebes 29 ein Drehmoment in die Spannspindel 19 eingeleitet. Dadurch wird die Auflagefläche 24 auf die Abstützfläche 26 gepreßt und bildet eine neue Schwenkachse 41. Um diese neue Schwenkachse 41 wird nun die Spannspindel 19 von der Formmasse 28 abgehoben, nach außen in Richtung Kontur 6 bewegt und mit ihrer Fläche 22 gegen die Abstützfläche 23 des Plattenzylinders 1 gedrückt. Somit ist eine eindeutige, splelfreie Position der Spannspindel 19 und der Einhängenase 3 erreicht. Diese zweite Schwenkbewegung erfolgt innerhalb eines Spiels zwischen Spannspindel 19 und Formmasse 28.Means of a tool engaging the hexagon 39 is now rotated on the second screw 34 so that this rotational movement on the shaft 36 and finally on the tooth segment 31 is transmitted. This causes the Clamping spindle 19 about its axis of rotation 20 with the Hook nose 3 towards the interior 21 of the Plate cylinder 1 and clamps the pressure plate 13. After the tension is almost reached, lies the bearing surface 24 of the hanging nose 3 on the Support surface 26 on. Beyond this position now a torque in by means of the worm gear 29 the clamping spindle 19 initiated. This will make the Contact surface 24 pressed onto the support surface 26 and forms a new pivot axis 41. Around this new Pivot axis 41 is now the clamping spindle 19 of the Molding compound 28 lifted outwards in the direction of contour 6 moved and with its surface 22 against the support surface 23 of the plate cylinder 1 pressed. So is one clear, splinter-free position of the clamping spindle 19 and the hooking nose 3 reached. This second Swiveling movement takes place within a game between Clamping spindle 19 and molding compound 28.

Anstelle der Formmasse 28 kann auch eine andere Lagerung für die Einhängenase 3 angeordnet sein. So kann beispielsweise die Einhängenase 3 nur an ihren Enden in axialer Richtung in zwei Lagerringen gelagert sein. Der Innendurchmesser der Lagerringe ist dabei etwas größer als der Außendruchmesser der darin gelagerten Spannspindel 19.Instead of the molding compound 28, another storage can also be used be arranged for the hooking nose 3. So can for example, the hook-in nose 3 only at its ends be supported in the axial direction in two bearing rings. Of the The inner diameter of the bearing rings is slightly larger than the outside diameter of those stored in it Clamping spindle 19.

In jedem Fall ist eine Lagerung als Zwangsführung vorgesehen, die die Auflagefläche 24 der Einhängenase 3 in Kontakt mit der Abstützfläche 26 des Plattenzylinders 1 bringt.In any case, storage is a priority provided that the bearing surface 24 of the hooking nose 3rd in contact with the support surface 26 of the plate cylinder 1 brings.

Einhängenase 3 und Plattenzylinder 1 sind mit Flächen 22, 24; 23; 26 versehen, die eine Zwangsführung bilden. Durch diese Zwangsführung wird die Einhängenase 3 spielfrei aus dem Kanal 11 heraus in Richtung Kontur 6 gegen den Plattenzylinder 1 gedrückt. Hanging nose 3 and plate cylinder 1 are with surfaces 22, 24; 23; 26 provided which form a positive guidance. Due to this forced guidance, the hook-in nose 3 without play out of the channel 11 in the direction of contour 6 pressed against the plate cylinder 1.
