Description

Die Erfindung betrifft einen Plattenzylinder einer Druckmaschine nach dem Oberbegriff von Anspruch 1.The invention relates to a plate cylinder of a printing press according to the Preamble of claim 1.

Die EP 1 155 837 A2 zeigt eine Vorrichtung zum Befestigen von biegsamen Druckplatten am Plattenzylinder, welche eine im Zylinderkörper angeordnete Klemmvorrichtung und eine außerhalb des Plattenzylinders angeordnete segmentierte Andrückleiste umfasst, wobei diese eine Klemmvorrichtung alle Druckplatten klemmt. Nachteil ist, dass bei einem Wechsel einer Druckplatte die Klemmvorrichtung die Enden aller Druckplatten freigibt, somit müssen zum Wechseln dieser einen Druckplatte die anderen nicht zu wechselnden Druckplatten auf dem Plattenzylinder mittels der segmentierten Andrückleiste angedrückt und gehalten werden, damit die Enden der nicht zu wechselnden Druckplatten nicht aus dem Spannkanal gleiten.EP 1 155 837 A2 shows a device for fastening flexible Pressure plates on the plate cylinder, which one arranged in the cylinder body Clamping device and one arranged outside the plate cylinder includes segmented pressure bar, this one clamping device all Pressure plates are jammed. The disadvantage is that when changing a printing plate Clamping device releases the ends of all pressure plates, so you have to Change this one pressure plate the other not to be changed Printing plates on the plate cylinder using the segmented pressure bar pressed and held so that the ends of the not to be changed Do not slide the pressure plates out of the clamping channel.

Der Erfindung liegt die Aufgabe zugrunde, einen Plattenzylinder einer Druckmaschine zu schaffen, welcher Spannungen der Druckplatten mit einfachen Mitteln erreicht.
Diese Aufgabe wird durch die kennzeichnenden Merkmale von Anspruch 1 gelöst.The invention has for its object to provide a plate cylinder of a printing press, which reaches tensions of the printing plates with simple means.
This object is achieved by the characterizing features of claim 1.

Von Bedeutung ist, dass die Spannschiene derart beweglich im Spannkanal angeordnet ist, so dass das vorlaufende Plattenende durch die in eine erste Position verbringbare Spannschiene mit einem Halteelement gegen eine Anlagefläche fixierbar ist, wonach nach Drehung des Plattenzylinders das nachlaufende Plattenende an der in eine zweite Position ausgefahrenen Spannschiene einhängbar ist und wonach die Spannschiene zur Spannung dieses Plattenendes wieder in eine dritte Position einziehbar ist. It is important that the tensioning rail is so movable in the tensioning channel is arranged so that the leading plate end through the in a first Positionable clamping rail with a holding element against one Contact surface is fixable, after which the rotation of the plate cylinder trailing plate end at the extended position in a second position Clamping rail can be hooked in and then the clamping rail for tensioning this plate end can be retracted into a third position.

Ein weiterer Vorteil ist, dass die Spannschiene durch ein Federelement in Bewegungsrichtung der Spannschienenbewegung spannbar ist, so dass die Einleitung der Spannkraft im Bereich der Plattenfixierung liegt.Another advantage is that the tensioning rail is connected by a spring element Direction of movement of the tensioning rail movement is tensionable, so that the Initiation of the tension lies in the area of the plate fixation.

Mittels der mit unterschiedlichen Bereichen (Schalterhebungen) bzw. einem Schaltprofil ausgestalteten Schubstange ist eine Ansprechbarkeit oder Betätigung jeder einzelnen Spannschiene und somit jeder einzelnen Druckplatte vom Leitstand aus möglich. Eine automatische oder halbautomatische Plattenspannvorrichtung kann mittels einer für die Schubstange vorgesehenen Verstelleinrichtung erreicht werden.By means of different areas (switch lifts) or one Switching profile designed push rod is a responsiveness or actuation every single tensioning rail and thus every single pressure plate from Control center possible. An automatic or semi-automatic Plate clamping device can be provided by means of a push rod Adjustment device can be reached.

Von Bedeutung ist, dass für die jeweilige Spanneinrichtung im Zylinder umfangsseitig mindestens ein fester Spalt für die Einführung der Plattenenden vorhanden ist. Von Vorteil ist, dass die Druckform beim Wechsel ihre Mehrfachnutzung gewährleistend nicht beschädigt wird. Das Zusammenwirken der Halteelemente beim Druckformwechsel mit den Anlageflächen im Spannkanal ermöglicht einen den Druckprozeß unter dem Aspekt einer Minimierung von Kanalstößen begünstigenden schmalen Kanalspalt am Umfang des Plattenzylinders. Die Kanalbreite ist vorzugsweise kleiner als 3,5 Millimeter. Erwähnenswert ist, dass durch den schmalen Spannkanal der Zylinderkörper nicht geschwächt wird und nur eine geringe Verschmutzungsgefahr der Spannschienen bzw. der gesamten Vorrichtung zum Befestigen von biegsamen Druckformen besteht.It is important that for the respective clamping device in the cylinder at least one fixed gap on the circumference for the insertion of the plate ends is available. The advantage is that the printing form when changing their Ensuring multiple use is not damaged. The interaction the holding elements when changing the printing form with the contact surfaces in the clamping channel enables the printing process to be minimized Channel gaps favoring narrow channel gap on the circumference of the Plate cylinder. The channel width is preferably less than 3.5 millimeters. It is worth mentioning that the cylinder body is not due to the narrow clamping channel is weakened and there is only a slight risk of contamination of the tensioning rails or the entire device for attaching flexible printing forms consists.

Bedeutend ist, dass bei einem einfachrunden Plattenzylinder mittels einer Schubstange zwei Spannschienen betätigt werden können. Dies ermöglicht eine geringere Schwächung des einfachrunden Zylinders durch Aufteilung der Funktionen.It is important that with a single round plate cylinder by means of a Push rod two tension rails can be operated. This enables one less weakening of the single round cylinder by dividing the Functions.

In der Stellung B befindet sich die Spannschiene 17 in der Klemmposition. Die Schubstange 13 hat in der Stellung B keinen Einfluss auf den Stößel 5 (siehe Fig. 5), da das Rollenelement 12 aufgrund des Abstandes nicht auf der Schubstange 13 ablaufen kann. In Stellung B wird der Stößel 5 und die Spannschiene 17 mittels der Druckfeder 6 nach innen gedrückt, das vorlaufende Plattenende 8 wird vom Halteelement 9 gegen eine Anlagefläche 16 am Plattenzylinder 1 gedrückt. Dabei kann das vorlaufende Plattenende 8 mit einer in einem spitzen Winkel abgekanteten Abkantung 28 ausgestaltet sein. Die Anlagefläche 16 ist entsprechend der Abkantung 28 des Plattenendes 8 schräg nach innen verlaufend ausgestaltet, um eine möglichst große Anlagefläche zu erwirken und einen Form- und/oder Kraftschluss zwischen Anlagefläche 16 und Plattenende 8 zu ermöglichen. Dieses Klemmen des Plattenendes 8 mittels des Halteelementes 9 wird nur benötigt, wenn das nachlaufende Plattenende 10 noch nicht fixiert ist. Somit ist die Druckform beim Druckformwechsel sicher und genau am Plattenzylinder 1 befestigbar. Die kanalförmige Aussparung 31 ist im Bereich der Schubstange 13 mit einem Füllstück 19 verschlossen. Das Füllstück 19 ist dazu mit dem Zylinderkörper des Plattenzylinders 1 verschlossen. Vorzugsweise ist das Füllstück 19 mit dem Zylinderkörper des Plattenzylinders 1 verschraubt oder verschweißt.

In an equivalent manner - not shown in detail - as an alternative to the axial Slidable push rod 13 is a radially movable element, for example a shaft equipped with switching cams can be used.

Fig. 3 zeigt das Spannen des nachlaufenden Plattenendes 10, der Stößel 5 wird zum Spannen zurück in eine Stellung C verbracht. In der Stellung C befindet sich die Spannschiene 17 in der Spannposition. Fig. 4 zeigt wie die Spannschiene 17 in die Stellung B oder in die Stellung C verbracht wird. Um die Spannschiene 17 in die Stellung A zu verbringen wird die Schubstange 13 mittels der Verstelleinrichtung 24 oder manuell in Richtung 27 axial verschoben. Die Schubstange 13 läuft während der axialen Verschiebung mittels ihrer Rollen oder Gleitelemente 14, 15 auf dem Zylinderkörper oder auf dem Füllstück 19 geführt ab und wird von der stirnseitig angeordnete Druckfeder 26 zurück gedrückt. Bei der Verschiebung der Schubstange 13 geraten die Rollen 12 der Stößel 5 nicht mehr in Eingriff mit der Schubstange 13, sondern liegen im Bereich der Senken 23 und können frei ausfedern. Die Stößel 5 werden durch die Kraft der vorgespannten Druckfedern 6 in Richtung der Senken 23 ausgelenkt und die Spannschiene 17 wird in radialer Richtung in die Stellung B oder in die Stellung C positioniert. Somit wird das nachlaufende Plattenende 10 vom Halteelement 11 bzw. von der Spannschiene 17 in den Spannkanal 18 gezogen und die Druckplatte um den Zylindermantel gespannt, wobei durch das Spannen der Druckform um den Zylindermantel das vorlaufende Plattenende 8 gegen die Anlagefläche 16 am Plattenzylinder 1 gezogen und somit fixiert wird.Fig. 3 shows the tensioning of the trailing plate end 10, the plunger 5 returned to position C for tensioning. In position C is the tensioning rail 17 in the tensioning position. 4 shows how the tensioning rail 17 is brought into position B or position C. To the tensioning rail 17 in to spend the position A, the push rod 13 by means of Adjustment device 24 or manually axially displaced in direction 27. The Push rod 13 runs during the axial displacement by means of its rollers or Sliding elements 14, 15 guided on the cylinder body or on the filler 19 and is pushed back by the compression spring 26 arranged at the end. In the Movement of the push rod 13 stops the rollers 12 of the plunger 5 in engagement with the push rod 13, but lie in the region of the depressions 23 and can rebound freely. The plunger 5 are biased by the force of the Compression springs 6 deflected in the direction of the depressions 23 and the tensioning rail 17th is positioned in the radial direction in position B or in position C. Consequently is the trailing plate end 10 of the holding member 11 or by the Tensioning rail 17 pulled into the tensioning channel 18 and the pressure plate around the Cylinder jacket tensioned, by tensioning the printing form around the Cylinder jacket the leading plate end 8 against the contact surface 16 on Plate cylinder 1 is pulled and thus fixed.

Die Stellung B dient zum fixieren des vorlaufenden Plattenendes 8 beim Druckformwechsel, wobei das vorlaufende Plattenende 8 mittels dem Halteelement 9 gegen die Anlagefläche 16 am Plattenzylinder 1 gedrückt wird.Position B is used to fix the leading plate end 8 at Printing form change, the leading plate end 8 by means of Holding element 9 is pressed against the contact surface 16 on the plate cylinder 1.

Es ist jeweils eine Schubstange 13 pro Spannschiene 17 vorgesehen (siehe Fig. 8).
Bei Plattenzylindern 1 mit kleinem Durchmesser ist jeweils von einer Stirnseite jeweils eine Schubstange 13 in die Aussparung 2 einsetzbar, wobei die beiden rechten Spannschienen 17 von einer von der rechten Stirnseite aus verstellbaren Schubstange 13 angesteuert werden und die beiden linken Spannschienen 17 von einer von der linken Stirnseite aus verstellbaren Schubstange 13 angesteuert werden (siehe Fig. 6). Um ein unabhängiges bzw. einzelnes Ansteuern der jeweiligen von einer Schubstange 13 betätigten Spannschienen 17 zu bewerkstelligen sind die Schaltprofile 21 der Schubstange 13 derart versetzt zueinander angeordnet, dass bei Betätigung einer der Spannschienen 17 mittels der Erhebungen 22 die nicht zu betätigende Spannschiene 17 im Bereich der Senken 23 liegt. Bei Plattenzylindern mit größerem Durchmesser können die beiden äußeren Spannschienen 17 jeweils von einer Schubstange 13 angesteuert werden, die mittleren zwei Spannschienen 17 können entweder von einer Schubstange 13 (siehe Fig. 7) oder von zwei Schubstangen (siehe Fig. 8) angesteuert werden.One push rod 13 is provided per tensioning rail 17 (see FIG. 8).
In the case of plate cylinders 1 with a small diameter, one push rod 13 can be inserted into the recess 2 from one end face, the two right tension rails 17 being controlled by a push rod 13 adjustable from the right end face and the two left tension rails 17 by one from the left Front side can be controlled from adjustable push rod 13 (see Fig. 6). In order to achieve independent or individual activation of the respective tensioning rails 17 actuated by a push rod 13, the switching profiles 21 of the push rod 13 are arranged offset to one another such that when one of the tensioning rails 17 is actuated by means of the elevations 22, the tensioning rail 17 which is not to be actuated is in the region of the Lower 23 lies. In the case of plate cylinders with a larger diameter, the two outer clamping rails 17 can each be controlled by a push rod 13, the middle two clamping rails 17 can be controlled either by a push rod 13 (see FIG. 7) or by two push rods (see FIG. 8).

Alternativ ist anstatt der kanalförmigen Aussparung 31 auch eine axiale Bohrung im Bereich der Schubstange 13 denkbar. Dann entfällt das untere Füllstück 19.Alternatively, there is also an axial bore instead of the channel-shaped recess 31 conceivable in the area of the push rod 13. Then the lower filler 19 is omitted.

Das Ausstoßen der Druckplatte erfolgt derart, dass das nachlaufende Plattenende 10 durch Verbringen der Spannschiene 17 in Stellung A freigegeben wird und mittels Verdrehen des Plattenzylinders 1 im Rückwärtsgang (Entgegen der Drehrichtung beim Druck) herausgeschoben wird. Das Freigeben des Plattenendes 10 kann derart erfolgen, dass das zum Spannen in Stellung C mittels der Spannschiene 17 hineingezogene und geklemmte Plattenende 10 zunächst gespannt wird und zum Freigeben des Plattenendes 10 die Spannschiene 17 in die Stellung A verbracht wird, wobei aufgrund des Freiwerdens der Kraft aus der Verspannung das Plattenende 10 aus dem Halteelement 11 und dem Spannkanal 18 herausrutscht. Das vorlaufende Plattenende 8 wird unmittelbar nach dem Freigeben des Plattenendes 10 wieder geklemmt, wobei die Spannschiene 17 mittels der freiwerdenden Federkraft des Federelementes 6 in die Stellung B gezogen wird. Die Bedienungsperson geht vor Ort und kann das vorlaufende Plattenende 8 aus der Spannschiene 17 bzw. dem Spannkanal 18 aushängen, wobei dazu die Spannschiene 17 in die Stellung A verbracht wird. Anschließend hängt die Bedienungsperson das vorlaufende Ende 8 der neuen Druckplatte im Spannkanal 18 ein, die Spannschiene 17 wird in Stellung B zum Klemmen des vorlaufenden Plattenendes 8 verbracht und durch Verdrehen des Plattenzylinders 1 in Drehrichtung Druck wird die neue Platte eingezogen, wobei beim Einhängen des nachlaufenden Endes 10 der neuen Druckplatte die Spannschiene 17 in die Stellung A verbracht wird und nach dem Einhängen mittels Verbringen der Spannschiene 17 in Stellung C das Plattenende 10 geklemmt und die Druckplatte sauber und exakt auf dem Zylinderumfang aufgespannt wird, wobei das Halteelement 9 in der Stellung C das vorlaufende Plattenende 8 nicht berührt und durch das Spannen der Druckform um den Zylindermantel das Plattenende 8 gegen die Anlagefläche 16 am Plattenzylinder 1 gezogen und fixiert wird. The printing plate is ejected in such a way that the trailing plate end 10 is released by moving the tensioning rail 17 in position A and by turning the plate cylinder 1 in reverse (counter to the Direction of rotation during printing) is pushed out. The release of the Plate end 10 can be made such that the clamping in position C plate end 10 drawn in and clamped by means of the tensioning rail 17 is initially tensioned and to release the plate end 10 Clamping rail 17 is brought into position A, due to the Release of the force from the bracing the plate end 10 from the Holding element 11 and the tensioning channel 18 slips out. The leading one Plate end 8 is immediately after the plate end 10 is released clamped, the tensioning rail 17 by means of the released spring force of the Spring element 6 is pulled into position B. The operator proceeds Place and can the leading plate end 8 from the tensioning rail 17 and the Unhook the tensioning channel 18, with the tensioning rail 17 in position A is spent.
