Description

Die Erfindung betrifft eine Vorrichtung zum Aufspannen von biegsamen Druckplatten auf Formzylinder von Rotationsdruckmaschinen gemäß dem Oberbegriff des Patentanspruches 1.The invention relates to a device for clamping flexible printing plates on forme cylinders of rotary printing presses according to the preamble of claim 1.

Die DE-OS 28 08 168 zeigt eine Vorrichtung zum Aufspannen von biegsamen Druckplatten auf Formzylinder von Rotationsdruckmaschinen. Hierzu sind in einer Plattenzylindergrube zwei bewegbare Einhängeleisten für abgekantete biegsame Druckplatten vorgesehen. Die Eine weist eine Aufnahme für einen vorlaufenden Druckplattenanfang, die Andere eine mittels einer Torsionsfeder vorgespannte Nase für ein nachlaufendes Druckplattenende auf. Zwischen den beiden Einhängeleisten ist eine Blattfeder angeordnet, deren Kraftwirkung bestrebt ist, die Einhängeleisten auseinander zu bewegen. Eine Verstellung der Einhängeleisten zum Umfangsregistern der Druckplatte erfolgt jeweils mittels Kegelkopfschrauben, die die Einhängeleisten beim Hineinschrauben in den Formzylinder gegen die Kraft der Blattfeder verschieben. Hierfür muß die Druckplatte allerdings nach zusätzlich Ausnehmungen aufweisen, um die Kegelkopfschrauben für ein Werkzeug zugänglich zu machen. Zur Arretierung in einer gewünschten Stellung sind zusätzlich Befestigungsschrauben vorgesehen, mit denen die Einhängeleisten lösbar am Formzylindergrund befestigt sind.DE-OS 28 08 168 shows a device for clamping flexible printing plates on forme cylinders of rotary printing machines. For this purpose, two movable suspension rails for folded flexible printing plates are provided in a plate cylinder pit. One has a receptacle for a leading printing plate start, the other has a nose that is biased by a torsion spring for a trailing printing plate end. A leaf spring is arranged between the two hanging strips, the force of which strives to move the hanging strips apart. An adjustment of the hanging strips to the circumferential registers of the pressure plate takes place in each case by means of conical head screws which move the hanging strips against the force of the leaf spring when screwing them into the forme cylinder. For this, however, the pressure plate must have additional recesses in order to make the cone-head screws accessible for a tool. For locking in a desired position, additional fastening screws are provided, with which the hanging strips are detachably fastened to the base of the forme cylinder.

Nachteilig an der bekannten DE-OS 28 08 168 ist, daß eine Schnellaufspannung der Druckplatte bzw. ein schnelles Umfangsregistern der Druckplatte nicht möglich ist, da hierzu eine große Anzahl von Spann- und Befestigungsschrauben betätigt werden müssen. Da keine Einrichtung vorgesehen ist, die Spannschrauben jeweils einer Einhängeleiste synchron zu verstellen, kann sich ein unerwünschtes Schränken der Druckplatte auf dem Formzylinder ergeben. Die gezeigte Vorrichtung ist außerdem nicht für Drehrichtungsumkehr des Plattenzylinders geeignet.A disadvantage of the known DE-OS 28 08 168 is that rapid clamping of the pressure plate or rapid circumferential registers of the pressure plate is not possible, since a large number of tensioning and fastening screws have to be actuated for this. Since no device is provided for synchronously adjusting the tensioning screws of each one of the suspension rails, undesired setting of the pressure plate on the forme cylinder can result. The device shown is also not suitable for reversing the direction of rotation of the plate cylinder.

Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung zum Aufspannen von biegsamen Druckplatten auf einen drehrichtungsumkehrbaren Formzylinder einer Rotationsdruckmaschine zu schaffen, die ein schnelles Aufspannen und Umfangsregistern der einzelnen Druckplatte ermöglicht.The invention has for its object to provide a device for clamping flexible printing plates on a reversible forme cylinder of a rotary printing press, which enables rapid clamping and peripheral registers of the individual printing plate.

Die Aufgabe wird erfindungsgemäß durch den kennzeichnenden Teil des Patentanspruches 1 gelöst.The object is achieved by the characterizing part of claim 1.

Die Vorteile der Erfindung liegen insbesondere darin, daß ein Druckplattenende beim Umfangsregistern automatisch dem Druckplattenanfang folgt. Außerdem kann ein die erfindungsgemäße Vorrichtung aufnehmender Zylinderkanal sehr schmal ausgeführt werden, so daß nahezu der gesamte Plattenzylinderumfang genutzt werden kann.The advantages of the invention are, in particular, that a printing plate end automatically follows the beginning of the printing plate in the peripheral register. In addition, a cylinder channel accommodating the device according to the invention can be made very narrow, so that almost the entire circumference of the plate cylinder can be used.

Ein Ausführungsbeispiel der Erfindung ist in den Zeichnungen dargestellt und wird im folgenden näher beschrieben. Es zeigen:

  • Fig. 1 eine Seitenansicht der Einhängeleiste gemäß Schnittverlauf I - I in Fig. 2,
  • Fig. 2 einen Querschnitt der Vorrichtung mit aufgespannter Druckpatte,
  • Fig. 3 einen Querschnitt der Vorrichtung durch einen Lagerbock mit aufgespannter Druckplatte gemäß Schnittverlauf III - III in Fig. 1.
An embodiment of the invention is shown in the drawings and will be described in more detail below. Show it:

  • 2 shows a cross section of the device with the printing plate clamped,
  • 3 shows a cross section of the device through a bearing block with a clamped pressure plate according to section III - III in FIG. 1.

Ein Formzylinder 1 ist in bekannter Weise in Seitengestellen einer Rotationsdruckmaschine gelagert. Der Formzylinder 1 weist eine achsparallele Grube 2 zur Aufnahme eines Trägers 3 auf. Der Träger 3 ist in der Grube 2 befestigt und weist ebenfalls einen nach oben weisenden achsparallelen Zylinderkanal 5 auf. In den Zylinderkanal 5 ist eine, in bzw. gegen Umlaufrichtung des Formzylinders 1 verschiebbare Einhängeleiste 4 und zwei federbelastete Nasen 6, 7 zum Halten eines nachlaufenden, gekanteten Druckplattenendes 8 angeordnet. Es ist möglich, im Zylinderkanal 5 axial nebeneinander auch zwei Druckplattenspanneinrichtungen 4, 6, 7 anzuordnen.A forme cylinder 1 is mounted in a known manner in the side frames of a rotary printing press. The forme cylinder 1 has an axially parallel pit 2 for receiving a carrier 3. The carrier 3 is fastened in the pit 2 and likewise has an axially parallel cylinder channel 5 pointing upwards. Arranged in the cylinder channel 5 is a suspension strip 4 which can be displaced in or against the direction of rotation of the forme cylinder 1 and two spring-loaded lugs 6, 7 for holding a trailing, edged pressure plate end 8. It is possible to arrange two pressure plate clamping devices 4, 6, 7 axially next to one another in the cylinder channel 5.

In einem Fußteil 9 der Einhängeleiste 4 ist eine nach unten weisende leistenlange Nut 11 vorgesehen. Die Nut 11 dient zur Aufnahme einer schwenkbaren Nockenwelle 12, die in Lagerböcken 13, 14 gelagert ist. Die Nockenwelle 12 weist einen Nocken 34 auf, der sich in axialer Richtung über die gesamte Länge der Nockenwelle 12 erstreckt. Selbstverständlich ist es auch möglich, eine zur Verstellung vorgesehene Welle exzentrisch zu lagern, wobei die Exzentrizität das Maß für den Verstellweg vorgibt.In a foot part 9 of the hanging strip 4, a downward, long, groove 11 is provided. The groove 11 serves to receive a pivotable camshaft 12, which is mounted in bearing blocks 13, 14. The camshaft 12 has a cam 34 which extends in the axial direction over the entire length of the camshaft 12. Of course, it is also possible to mount a shaft provided for adjustment eccentrically, the eccentricity specifying the measure of the adjustment path.

Bei einer Anordnung von mehreren Spanneinrichtungen 4, 6, 7 nebeneinander werden jeweils zwei benachbarte Wellenenden 15 in einem Lagerbock 14 gelagert, der an den Grund des Zylinderkanals 5 geschraubt ist. Der Lagerbock 13 ist an einem Ende des Formzylinders 1 in einem schmalen Spalt 47 zwischen der Einhängeleiste 4 und einem Schmitzring 48 des Formzylinders 1 angeordnet und ebenfalls mit dem Formzylinder 1 verschraubt. Der Lagerbock 13 weist in einer horizontalen Senkbohrung 49 eine Stell- und Arretiervorrichtung 51 auf. Diese besteht aus einer runden Scheibe 52, die schwergängig drehbar in der Senkbohrung 49 des Lagerbockes 13 gelagert ist. Die Scheibe 52 sitzt fest auf dem als Sechskantkopf 53 ausgebildeten rechten Ende der Nockenwelle 12 und wird dort mittels eines Sicherungsringes 54 gehalten. Der Sechskantkopf 53 ragt über den Lagerbock 13 hinaus in den Spalt 47 hinein, so daß er dort leicht von oben mit einem Werkzeug betätigt werden kann. Eine Arretierschraube 56 sichert die jeweilige Stellung der Nockenwelle 12. Ein Kopfteil 18 der Einhängeleiste 4 weist zwei entgegengesetzte Einhängekanten 19, 21 auf. Die Nasen 6, 7 sind jeweils auf einer schwenkbaren Rohrwelle 22; 23 befestigt. Die Rohrwellen 22; 23 sind jeweils in einer zur Grube 2 weisenden Lagerhalbschale 24; 26 in einer linken bzw. rechten Grubenseitenwand 27; 28 in Höhe der Einhängekanten 19, 21 gelagert. Zur Sicherung gegen Herausfallen der Rohrwellen 22, 23 ist jeweils eine Halterungsschiene 16; 17 an die Grubenseitenwand 27; 28 geschraubt. Die Halterungsschiene 16; 17 weist eine dem Radius der Rohrwelle 22; 23 entsprechende Ausnehmung 30; 38 auf und umschließt gemeinsam mit der Lagerhalbschale 24; 26 einen dreiviertel Umfang der Rohrwelle 22; 23. Die Rohrwellen 22, 23 tragen im Inneren jeweils koaxial eine Torsionsfeder 29; 31, die in bekannter Weise - DE-OS 28 08 168 - an der Rohrwelle 22; 23 und am Formzylinder 1 befestigt ist.In the case of an arrangement of a plurality of clamping devices 4, 6, 7 next to one another, two adjacent shaft ends 15 are each mounted in a bearing block 14 which is screwed to the base of the cylinder channel 5. The bearing block 13 is arranged at one end of the forme cylinder 1 in a narrow gap 47 between the hanging bar 4 and a bearer ring 48 of the forme cylinder 1 and is also screwed to the forme cylinder 1. The bearing block 13 has an adjusting and locking device 51 in a horizontal counterbore 49. This consists of a round disk 52, which is rotatably mounted in the counterbore 49 of the bearing block 13 with difficulty. The disk 52 sits firmly on the right end of the camshaft 12, which is designed as a hexagon head 53, and is held there by means of a locking ring 54. The hexagon head 53 protrudes beyond the bearing block 13 into the gap 47, so that it can be easily actuated from above with a tool. A locking screw 56 secures the respective position of the camshaft 12. A head part 18 of the hanging bar 4 has two opposite hanging edges 19, 21. The lugs 6, 7 are each on a pivotable tubular shaft 22; 23 attached. The tubular shafts 22; 23 are each in a bearing shell 24 facing the pit 2; 26 in a left or right pit side wall 27; 28 mounted at the level of the hooking edges 19, 21. To prevent the tubular shafts 22, 23 from falling out, a mounting rail 16; 17 to the pit side wall 27; 28 screwed. The mounting rail 16; 17 has a the radius of the tubular shaft 22; 23 corresponding recess 30; 38 on and together with the bearing half-shell 24; 26 a three-quarter circumference of the tubular shaft 22; 23. The tubular shafts 22, 23 each carry a torsion spring 29 coaxially inside; 31, in a known manner - DE-OS 28 08 168 - on the tubular shaft 22; 23 and is attached to the forme cylinder 1.

Die Einhängeleiste 4 weist an ihren Enden 39, 41 jeweils zwei Absätze 42, 43 auf, die jeweils unter einen Vorsprung 44, 46 der Lagerböcke 13; 14 geschoben sind und damit in Umfangsrichtung gesehen eine horizontale Führung bilden, wodurch ein Herausgleiten der Einhängeleiste 4 aus dem Zylinderkanal 5 in vertikaler Richtung vermieden wird.The hanging bar 4 has at its ends 39, 41 two shoulders 42, 43, each under a projection 44, 46 of the bearing blocks 13; 14 are pushed and thus seen in the circumferential direction form a horizontal guide, whereby slipping out of the hanging bar 4 from the cylinder channel 5 is avoided in the vertical direction.

Zum Spannen einer Druckplatte 32 auf dem Formzylinder 1 wird ein vorlaufender Druckplattenanfang 33 je nach Drehrichtung in die Einhängekante 19; 21 eingehängt. Die Rohrwelle 22; 23 wird mittels eines Werkzeugs in Formzylinderdrehrichtung gegen die Kraft der Torsionsfeder 29; 31 geschwenkt, bis das nachlaufende Druckplattenende 8 über die Nase 6; 7 eingehängt werden kann. Die durch das Verschwenken vorgespannte Torsionsfeder 29; 31 spannt die Druckplatte 32 auf dem Formzylinder 1 beim Freigeben vom Werkzeug.To clamp a printing plate 32 on the forme cylinder 1, a leading printing plate start 33, depending on the direction of rotation, is inserted into the hanging edge 19; 21 hung. The tubular shaft 22; 23 is by means of a tool in the direction of the cylinder rotation against the force of the torsion spring 29; 31 pivoted until the trailing pressure plate end 8 over the nose 6; 7 can be hung. The torsion spring 29; 31 clamps the pressure plate 32 on the form cylinder 1 when releasing the tool.

Zur Umfangsregisterverstellung wird die Nockenwelle 12 mittels eines Werkzeuges in oder gegen Formzylinderdrehrichtung verschwenkt und mit der Schraube 56 in gewünschter Position arretiert. Hierbei drückt der Nocken 34 der Nockenwelle 12 gegen eine Seitenwand 36; 37 der Nut 11 und verschiebt dadurch den in die Einhängeleiste 4 gehängten vorlaufenden Druckplattenanfang 33, gegen die oder mit der, auf das Druckplattenende 8 wirkenden Spannkraft der Torsionsfeder 29; 31 in oder gegen Umfangsrichtung.To adjust the circumferential register, the camshaft 12 is pivoted in or against the direction of rotation of the forme cylinder by means of a tool and locked in the desired position with the screw 56. Here, the cam 34 of the camshaft 12 presses against a side wall 36; 37 of the groove 11 and thereby displaces the leading pressure plate beginning 33 suspended in the hanging bar 4, against or with the tension force of the torsion spring 29 acting on the pressure plate end 8; 31 in or against the circumferential direction.
