Abstract

A rotatable spindle (7) is fitted with one or more leaf springs (8). The spindle has an entrainment edge (10) with which it engages on a V-shaped notch (11) of the leading plate arm (5) of the pressure plate (6). A lever fixed on the spindle is connected for articulated movement to a spring-in swivel lever. Both levers can deflect each side of a stretched position. When fixing the pressure plate the leading plate arm is hung on the edge of a cylinder ditch (2) and then drawn into the ditch. The flexible pressure plate is then wound round the sleeve of the forming cylinder and the trailing plate arm is guided into the cylinder ditch. Finally the trailing plate arm is seized and drawn into the cylinder ditch. <IMAGE>

Description

Die Erfindung betrifft eine Vorrichtung zum Befestigen einer biegsamen Druckplatte auf den Formzylinder einer Druckmaschine nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a device for attaching a flexible printing plate to the forme cylinder of a printing press according to the preamble of claim 1.

Die EP 534 579 A2 zeigt eine Plattenspannung, bei der der Formzylinder eine in Achsrichtung verlaufende Zylindergrube aufweist, deren eine Kante den vorlaufenden Plattenschenkel trägt. Weiterhin enthält die Zylindergrube eine drehbare Spindel, an der über die Breite des Formzylinders verteilt U-förmige Blattfedern angeordnet sind. Ein Schenkel der Blattfedern ist hakenförmig abgekantet und greift beim Drehen der Spindel in den ebenfalls hakenförmig abgekanteten nachlaufenden Plattenschenkel ein. Der andere Schenkel der Federn drückt den vorlaufenden Plattenschenkel gegen die Wand der Zylindergrube. Bei dieser Vorrichtung ist nachteilig, daß der vorlaufende Plattenschenkel an der Wand der Zylindergrube nicht zuverlässig festgehalten wird.EP 534 579 A2 shows a plate tension in which the forme cylinder has a cylinder pit running in the axial direction, one edge of which carries the leading plate leg. Furthermore, the cylinder pit contains a rotatable spindle on which U-shaped leaf springs are arranged distributed over the width of the forme cylinder. One leg of the leaf springs is bent like a hook and, when the spindle is turned, engages in the trailing plate leg, which is also bent like a hook. The other leg of the springs presses the leading plate leg against the wall of the cylinder pit. A disadvantage of this device is that the leading plate leg is not reliably held on the wall of the cylinder pit.

Es ist Aufgabe der Erfindung, eine Vorrichtung zum Befestigen einer biegsamen Druckplatte zu schaffen, die die Druckplatte zuverlässig spannt.It is an object of the invention to provide a device for fastening a flexible pressure plate, which reliably clamps the pressure plate.

Erfindungsgemäß wird diese Aufgabe bei einer gattungsgemäßen Vorrichtung durch die Anwendung der Merkmale des Kennzeichens des Patentanspruchs 1 sowie durch ein Verfahren gemäß dem Patentanspruch 6 gelöst. Die Vorrichtung sichert den vorlaufenden Plattenschenkel nicht nur an der Wand der Zylindergrube, sondern erfaßt und spannt diesen, d. h. zieht ihn in die Zylindergrube. Dadurch wird die vorlaufende Plattenkante lagerichtig auf die Kante der Zylindergrube gezogen. Es wird die Druckplatte parallel zur Kanalkante auf dem Formzylinder positioniert, bevor sie um diesen gewickelt wird. Es werden also Registerfehler, insbesondere auch Diagonalregisterfehler, beim Spannen der Druckplatte vermieden.According to the invention, this object is achieved in a generic device by using the features of the characterizing part of patent claim 1 and by a method according to patent claim 6. The device not only secures the leading plate leg on the wall of the cylinder pit, but grips and tensions it, ie pulls it into the cylinder pit. This pulls the leading plate edge in the correct position onto the edge of the cylinder pit. The pressure plate is parallel to the channel edge on the Form cylinder positioned before it is wrapped around it. Register errors, in particular also diagonal register errors, when clamping the printing plate are thus avoided.

Der in Fig. 1 ausschnittsweise dargestellte Formzylinder 1 weist eine in Achsrichtung verlaufende Zylindergrube 2 auf. Eine Grubenwand 3 verläuft spitzwinkelig zur Zylindermantelfläche und bildet mit dieser eine Kante 4, an der der vorlaufende Plattenschenkel 5 der Druckplatte 6 aufgenommen wird. In der Zylindergrube 2 ist eine Spindel 7 angeordnet, die an den Enden der Zylindergrube 2, nicht dargestellt, drehbar gelagert ist. Die Spindel 7 trägt über die Breite der zu spannenden Druckplatte 6 verteilt mehrere um etwa 90° hakenförmige abgewinkelte Blattfedern 8. Diese arbeiten mit dem ebenfalls um etwa 90° hakenförmig abgewinkelten Ende des nachlaufenden Plattenschenkels 9 zusammen. Statt der einzelnen Blattfedern 8 könnte auch eine sich über die Breite der Druckplatte erstreckende durchgehende Blattfeder vorgesehen sein. Die Spindel 7 besitzt weiterhin eine Mitnahmekante 10, die mit einer V-förmigen Kerbe 11 des vorlaufenden Plattenschenkels 5 zusammenarbeitet.The forme cylinder 1 shown in detail in FIG. 1 has a cylinder pit 2 running in the axial direction. A pit wall 3 extends at an acute angle to the cylindrical surface and forms with it an edge 4 on which the leading plate leg 5 of the pressure plate 6 is received. A spindle 7 is arranged in the cylinder pit 2 and is rotatably mounted at the ends of the cylinder pit 2, not shown. The spindle 7 carries several leaf springs 8 distributed over the width of the pressure plate 6 to be tensioned, and these co-operate with the end of the trailing plate leg 9 which is also bent around a 90 ° hook. Instead of the individual leaf springs 8, a continuous leaf spring extending over the width of the pressure plate could also be provided. The spindle 7 also has a driving edge 10, which cooperates with a V-shaped notch 11 of the leading plate leg 5.

An einem Ende der Spindel 7 ist ein Hebel 12 befestigt, der gelenkig mit einem einfederbaren Schwenkhebel 13 verbunden ist (Fig. 3). Der Schwenkhebel 13 enthält eine Stange 14, auf die gegen die Kraft einer Druckfeder 15 ein Gabelkopf 16 einfederbar ist. Mit einer Walze 17 stützt sich der Schwenkhebel 13 in einem Widerlager 18 schwenkbar ab. Weiterhin drückt der Schwenkhebel 13 mit seinem federbelasteten Gabelkopf 16 auf einen Bolzen 19 des Hebels 12.At one end of the spindle 7, a lever 12 is fastened, which is connected in an articulated manner to a deflectable pivot lever 13 (FIG. 3). The pivot lever 13 contains a rod 14 on which a fork head 16 can be deflected against the force of a compression spring 15. With a roller 17, the pivot lever 13 is pivotally supported in an abutment 18. Furthermore, the pivot lever 13 presses with its spring-loaded fork head 16 onto a bolt 19 of the lever 12.

Für die Montage der Druckplatte 6 nimmt die Spannspindel 7 zunächst die in Fig. 1 gezeigte Stellung ein. Die entsprechende Stellung der die Spindel 7 betätigenden Hebel 12 und 13 ist in Fig. 3 dargestellt. Der einfederbare Schwenkhebel 13 drückt dabei den Hebel 12 in eine Anschlagstellung. Im Ausführungsbeispiel schlägt der Hebel 12 am Zapfen 20 des Formzylinders 1 an. Nunmehr wird die Druckplatte 6 mit ihrem vorlaufenden Plattenschenkel 5 an der Kante 4 der Zylindergrube 2 eingehängt. Anschließend wird die Spindel 7 geschwenkt. Hierzu werden der Hebel 12 und der Schwenkhebel 13 in ihre Strecklage, d. h. die Verbindungslinie ihrer Schwenkpunkte, und weiter in dieser Richtung über die Strecklage hinaus bewegt, bis die Mitnahmekante 10 an der Kerbe 11 der Druckplatte 6 anliegt und die dabei aufgebrachte Spannkraft der Druckkraft des Spannhebels 13 das Gleichgewicht hält. Dabei wird die Vorderkante der Druckplatte 6 exakt parallel zur Kante 4 der Zylindergrube 2 ausgerichtet. Anschließend wird die gut ausgerichtete Druckplatte 6 unter Drehung des Formzylinders 1 auf diesen aufgewickelt. Danach wird die Spindel 7 in die in Fig. 1 gezeichnete Stellung zurückgeschwenkt, wobei der Hebel 12 am Zapfen 20 anschlägt. Nachdem der nachlaufende Plattenschenkel 9 in die Zylindergrube 2 eingedrückt wurde, wird die Spindel 7 in die in Fig. 2 gezeigte Stellung geschwenkt. Hierzu werden der Hebel 12 und der Schwenkhebel 13 wieder über ihre Strecklage hinaus ausgelenkt. Dabei spannt die Mitnahmekante 10 wiederum den vorlaufenden Plattenschenkel 5, und die Blattfedern 8 greifen in die hakenförmige Abkantung des nachlaufenden Plattenschenkels 9 und spannen diesen. Somit sind sowohl der vorlaufende als auch der nachlaufende Plattenschenkel 5, 9 unter der Kraft der Druckfeder 15 vorgespannt, d. h. die Spindel 7 dreht sich so weit, bis die Spannkräfte auf die Plattenschenkel 5, 9 der Federkraft des Schwenkhebels 13 das Gleichgewicht halten.For the assembly of the pressure plate 6, the clamping spindle 7 first assumes the position shown in FIG. 1. The corresponding position of the levers 12 and 13 actuating the spindle 7 is shown in FIG. 3. The deflectable pivot lever 13 presses the lever 12 into a stop position. In the exemplary embodiment, the lever 12 strikes the pin 20 of the forme cylinder 1. Now the pressure plate 6 is suspended with its leading plate leg 5 on the edge 4 of the cylinder pit 2. Then the spindle 7 is pivoted. For this purpose, the lever 12 and the pivot lever 13 are moved into their extended position, that is, the connecting line of their pivot points, and further in this direction beyond the extended position until the driving edge 10 bears against the notch 11 of the pressure plate 6 and the tension force applied in the process of the pressure force of the Clamping lever 13 keeps the balance. The front edge of the pressure plate 6 is aligned exactly parallel to the edge 4 of the cylinder pit 2. The well-aligned printing plate 6 is then wound onto the forme cylinder 1 while rotating it. Thereafter, the spindle 7 is pivoted back into the position shown in FIG. 1, the lever 12 striking the pin 20. After the trailing plate leg 9 has been pressed into the cylinder pit 2, the spindle 7 is pivoted into the position shown in FIG. 2. For this purpose, the lever 12 and the pivot lever 13 are again deflected beyond their extended position. The driving edge 10 in turn tensions the leading plate leg 5 and the leaf springs 8 reach into the hook-shaped fold of the trailing plate leg 9 and tension it. Thus, both the leading and the trailing plate legs 5, 9 are biased under the force of the compression spring 15, ie the spindle 7 rotates until the clamping forces on the plate legs 5, 9 keep the spring force of the pivot lever 13 in balance.

Zur Demontage der Druckplatte 6 wird die Spindel 7 in die in Fig. 1 gezeigte Stellung geschwenkt. Anschließend wird der nachlaufende Plattenschenkel 9 aus der Zylindergrube 2 entnommen, die Druckplatte 6 durch Rückdrehung des Formzylinders 1 von diesem abgewickelt und die Druckplatte 6 mit ihrem vorlaufenden Plattenschenkel 5 aus der Zylindergrube 2 herausgehoben.To remove the pressure plate 6, the spindle 7 is pivoted into the position shown in FIG. 1. Subsequently, the trailing plate leg 9 is removed from the cylinder pit 2, the pressure plate 6 is unwound from the cylinder 1 by rotating the plate cylinder 1, and the pressure plate 6 with its leading plate leg 5 is lifted out of the cylinder pit 2.

Die Verschwenkung der Stellspindel in die eine oder andere Richtung erfolgt vorteilhaft durch Aufbringen einer Kraft F1 bzw. F2 auf den Hebel 12 diesseits oder jenseits seines Schwenkpunktes (siehe Fig. 3). Die Kräfte können durch im Gestell angeordnete Arbeitszylinder aufgebracht werden. Überhaupt ist die Vorrichtung gut für einen automatischen Plattenwechsel geeignet.The pivoting of the adjusting spindle in one direction or the other is advantageously carried out by applying a force F1 or F2 to the lever 12 on this side or beyond its pivot point (see FIG. 3). The forces can be applied by working cylinders arranged in the frame. In general, the device is well suited for an automatic plate change.

Die Kerbe 11 des vorlaufenden Plattenschenkels 5 ist im Ausführungsbeispiel V-förmig gestaltet. Dabei eigent sich der eine Schenkel der Kerbe 11 gut für die Mitnahme durch die Mitnahmekante 10, während sich der zweite Schenkel vorteilhaft an der Grubenwand 3 abstützt. Unter Benutzung der Erfindung kann die Kerbe auch anderweitig ausgebildet sein, beispielsweise U-förmig. Der vorlaufende Plattenschenkel 5 kann auch Noppen tragen, an denen die Mitnahmekante 10 angreift. Auch kann der vorlaufende Plattenschenkel mit in Achsrichtung des Zylinders verlaufenden Schlitzen versehen sein, in deren Bereich die Druckplatte, Mitnahmestege bildend, zur Spindel hin herausgewölbt ist.The notch 11 of the leading plate leg 5 is V-shaped in the embodiment. One leg of the notch 11 is well suited for being carried along by the driving edge 10, while the second leg is advantageously supported on the pit wall 3. Using the invention, the notch can also be designed in another way, for example U-shaped. The leading plate leg 5 can also wear knobs on which the driving edge 10 engages. The leading plate leg can also be provided with slots running in the axial direction of the cylinder, in the area of which the pressure plate, forming driving webs, is arched out towards the spindle.

Gemäß einer weiteren Ausführungsvariante (Figuren 4 und 5) weist der nachlaufende Plattenschenkel 21 der zu spannenden Druckplatte 22 in Achsrichtung des Formzylinder 23 angeordnete fensterförmige Aussparungen 24 auf. In diese greifen in der Spannstellung die hakenförmige Blattfedern 25 der Spindel 26 ein. Weiterer Aufbau und Funktion gleichen dem vorherigen Ausführungsbeispiel und werden deshalb nicht näher beschrieben.According to a further embodiment variant (FIGS. 4 and 5), the trailing plate leg 21 of the pressure plate 22 to be tensioned has Axial direction of the forme cylinder 23 arranged window-shaped recesses 24. In the tensioned position, the hook-shaped leaf springs 25 of the spindle 26 engage in these. Further structure and function are the same as the previous exemplary embodiment and are therefore not described in detail.
