Abstract

Die Erfindung bezieht sich auf eine Spannschiene am Plattenzylinder von Rotationsdruckmaschinen zum Spannen des nachlaufenden Plattenendes, mit einer Klemmeinrichtung für das Plattenende und mit Spannschrauben, die entgegen der Kraft von Druckfedern die aufgelegte und geklemmte Druckplatte spannen, wobei auf diese Spannschiene eine unabhängige Zusatzkraft kurzzeitig ausgeübt werden kann, um das Wechseln der Druckplatte zu vereinfachen und zu beschleunigen.The invention relates to a tensioning rail on the plate cylinder of rotary printing presses for tensioning the trailing plate end, with a clamping device for the plate end and with tensioning screws which tension the applied and clamped pressure plate against the force of compression springs, an independent additional force being exerted briefly on this tensioning rail can to simplify and accelerate the change of the printing plate.

Description

Die Erfindung bezieht sich auf eine Spannschiene gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a tensioning rail according to the preamble of claim 1.

Derartige Spanneinrichtungen dienen dem Aufspannen von biegsamen Druckplatten auf dem Plattenzylinder von Rotationsdruckmaschinen. Insbesondere die, in Drehrichtung des Plattenzylinders gesehen, nachlaufende Plattenspannschiene muß über eine Vielzahl von Spannschrauben die Spannkräfte auf das Plattenende übertragen. Wegen der Nachgiebigkeit der Druckplatte bis zum Erreichen der richtigen Aufspannkraft sind mehrere volle Spannschraubenumdrehungen notwendig. Hierbei sind die einzelnen Spannschrauben abwechselnd jeweils ein Stück anzuziehen, um ein Verkanten der in der Spannschiene geklemmten Druckplatte zu vermeiden. Zum Aufspannen muß daher das Spannschraubenwerkzeug häufig umgesetzt werden.Such clamping devices are used to clamp flexible printing plates on the plate cylinder of rotary printing presses. In particular, the trailing plate clamping rail, seen in the direction of rotation of the plate cylinder, must transmit the clamping forces to the plate end via a large number of clamping screws. Due to the resilience of the pressure plate until the correct clamping force is reached, several full turns of the clamping screw are necessary. The individual clamping screws must be tightened alternately one piece at a time in order to prevent the pressure plate clamped in the clamping rail from tilting. The clamping screw tool must therefore be frequently implemented for clamping.

Zum Ausrichten der Spannschiene vor der nächsten Plattenmontage muß diese über die Spannschrauben wieder in ihre Ausgangsstellung bewegt werden, so daß auch hierfür ein häufiges Umsetzen des Werkzeuges erforderlich ist. Hierbei lassen sich die Spannschrauben nicht von Hand verdrehen, denn die Kraft der Druckfedern zwischen den beiden Spannschienen muß so hoch sein, daß diese sich beim Maschinenlauf ohne aufgespannte Druckplatte nicht bewegen.To align the clamping rail before the next plate assembly, it must be moved back to its starting position using the clamping screws, so that the tool must be moved frequently. Here, the tensioning screws cannot be turned by hand, because the force of the compression springs between the two tensioning rails must be so high that they do not move when the machine is running without the pressure plate clamped.

Bei der Demontage erweist es sich häufig, daß die Druckplatte durch Farb- und Gummierungsreste im geöffneten Schlitz der Spannschiene verklebt ist. Ein Lösen der Druckplatte ohne Beschädigung derselben ist dann nur durch ein weiteres zeitraubendes Anziehen der Spannschrauben möglich; was den Weg, um den die Schrauben in ihre Ausgangslage zurückgedreht werden müssen, noch vergrößert. Berücksichtigt man, daß bei modernen Druckmaschinen mit mehreren Druckwerken eine entsprechende Anzahl von Druckplatten zu wechseln ist, so muß heute von erheblichen Umrüstzeiten ausgegangen werden, die den Gesamtwirkungsgrad der Druckmaschine verschlechtern.When dismantling, it often turns out that the printing plate due to ink and rubber residues in the open Slot of the tensioning rail is glued. A loosening of the pressure plate without damaging it is then only possible by further tightening the tensioning screws; which increases the distance that the screws have to be turned back to their original position. If one takes into account that a corresponding number of printing plates has to be exchanged in modern printing presses with several printing units, considerable changeover times must be assumed today, which deteriorate the overall efficiency of the printing press.

Die Aufgabe der Erfindung ist es, die Feder- und Klebekraft der Druckplatte an der Spannschiene zu überwinden und dadurch den Spannvorgang zu beschleunigen.The object of the invention is to overcome the spring and adhesive force of the pressure plate on the tensioning rail and thereby accelerate the tensioning process.

Die Aufgabe wird gemäß dem 'Kennzeichen des Anspruchs 1 gelöst. Durch den Einsatz des Hebelwerkzeugs und dessen Hebelwirkung läßt sich eine unabhängige Zusatzkraft in die hintere Spannschiene kurzzeitig einleiten, wodurch die Federkraft überwunden wird, so daß die Spannschrauben beim Einlegen einer neuen Druckplatte sehr schnell von Hand zurückgedreht werden können. Soll eine Druckplatte nach Beendigung der Druckarbeit vom Plattenzylinder abgenommen werden, und das nachlaufende Plattenende ist in der Spannschiene verklebt, so läßt sich mit Hilfe des Hebelwerkzeugs die Spannschiene kurzzeitig in Spannrichtung bewegen, wodurch die Verklebung gelöst wird. Durch diese unabhängigen Zusatzkräfte, die mit Hilfe eines Hebelwerkzeugs aufgebracht werden, das normalerweise an der Druckmaschine vorhanden ist und für andere Tätigkeiten benötigt wird, läßt sich innerhalb kürzester Zeit eine Druckplatte vom Plattenzylinder abnehmen und die Spannschiene in ihre Ausgangsposition zurückbewegen. Lediglich zum genauen Aufspannen einer neuen Druckplatte sind sodann noch die Spannschrauben mit Hilfe eines entsprechenden Werkzeuges zu betätigen.The object is achieved according to the 'characterizing part of claim 1. Through the use of the lever tool and its leverage, an independent additional force can be briefly introduced into the rear clamping rail, whereby the spring force is overcome, so that the clamping screws can be turned back very quickly by hand when inserting a new pressure plate. If a printing plate is to be removed from the plate cylinder after the printing work has been completed and the trailing plate end is glued in the clamping rail, the clamping rail can be moved briefly in the clamping direction with the help of the lever tool, thereby releasing the bond. These independent additional forces, which are applied with the aid of a lever tool that is normally present on the printing press and is required for other activities, allow a printing plate to be removed from the plate cylinder in a very short time and the tensioning rail to be moved back into its starting position. Just for the exact Clamping a new pressure plate, the clamping screws are then to be actuated with the aid of an appropriate tool.

Die Unteransprüche kennzeichnen vorteilhafte Ausgestaltungen- der beschriebenen Lösung und ermöglichen auch ein schnelles Ausrichten der Spannschiene in seitlicher Richtung, wobei es unerheblich ist, ob eine geteilte hintere Spannschiene Verwendung findet.The subclaims characterize advantageous embodiments of the solution described and also enable rapid alignment of the tensioning rail in the lateral direction, it being irrelevant whether a split rear tensioning rail is used.

Ein Ausführungsbeispiel der Erfindung ist in den Zeichnungen schematisch dargestellt. Es zeigen:

  • Fig. 1 eine Draufsicht auf die Spannschienen im Plattenzylinder,
  • Fig. 2 einen Teilquerschnitt durch die Spanneinrichtung.
An embodiment of the invention is shown schematically in the drawings. Show it:
  • 1 is a plan view of the clamping rails in the plate cylinder,
  • Fig. 2 shows a partial cross section through the clamping device.

Bei Offsetrotationsdruckmaschinen werden auf den Plattenzylinder 1 dünne Druckplatten 2 aufgespannt. In einem Zylinderkanal 3 sind Spannmittel vorgesehen, um die Platte exakt und registerhaltig auf den Plattenzylinder 1 aufzuspannen. Hierzu dienen Spannschienen 4,5, denen Klemmschienen 6,7 zugeordnet sind, die wiederum über Klemmexzenter 8,9 betätigt werden. Das vorlaufende Plattenende 10 wird zwischen Spannschiene 5 und Klemmschiene 7 nach dem registerhaltigen Ausrichten festgeklemmt und die Druckplatte 2 durch Drehen des Plattenzylinders 1 aufgelegt.In offset rotary printing machines, thin printing plates 2 are clamped onto the plate cylinder 1. Clamping means are provided in a cylinder channel 3 in order to clamp the plate precisely and in register on the plate cylinder 1. For this purpose, clamping rails 4.5 are used, to which clamping rails 6.7 are assigned, which in turn are actuated via clamping eccentrics 8.9. The leading plate end 10 is clamped between the clamping rail 5 and the clamping rail 7 after the register-oriented alignment and the pressure plate 2 is placed on it by rotating the plate cylinder 1.

Auch das nachlaufende Plattenende 11 wird zwischen der Spannschiene 4 und Klemmschiene 6 durch Verdrehen des Klemmexzenters 8 festgeklemmt, und danach die Druckplatte 2 über Spannschrauben 12 gespannt. Hierbei stützen sich die Spannschrauben 12 am Anschlag 13 ab. Die zwischen den Spannschienen 4 und 5 vorgesehenen Druckfedern 14 sollen eine ungewollte Bewegung der Spannschienen bei nichteingelegter Druckplatte verhindern. Beide Spannschienen 4,5 sind in Schienen 15 geführt, die auf dem Grund 16 des Zylinderkanals 3 befestigt sind.The trailing plate end 11 is also clamped between the clamping rail 4 and clamping rail 6 by turning the clamping eccentric 8, and then the pressure plate 2 stretched over clamping screws 12. Here, the clamping screws 12 are supported on the stop 13. The compression springs 14 provided between the tensioning rails 4 and 5 are intended to prevent unwanted movement of the tensioning rails when the pressure plate is not inserted. Both tensioning rails 4, 5 are guided in rails 15, which are fastened to the base 16 of the cylinder channel 3.

An der Spannschiene 4 für das nachlaufende Plattenende 11 sind Stecköffnungen 17 vorgesehen, die vorteilhaft an einem Flachkörper 18 angeordnet sind, der wiederum über eine Schraube 19 an der Spannschiene 4 befestigt ist. Fluchtend zu den Stecköffnungen 17 sind im Grund 16 des Zylinderkanals 3 Ausnehmungen 20 vorgesehen, die im gezeigten Ausführungsbeispiel als Bohrungen ausgebildet sind. Ein Hebelwerkzeug 21, bei dem es sich um einen Steckdorn handeln kann, läßt sich durch die Stecköffnung 17 hindurch in die Ausnehmung 20 einführen, so daß über die Hebelwirkung des Steckdorns eine unabhängige Zusatzkraft in die hintere Spannschiene 4 kurzzeitig eingeleitet werden kann. Diese Kraft kann nun die Spannschiene in Spannrichtung bewegen und hierdurch ein eventuell verklebtes Plattenende lösen. Sie kann aber auch die Federkraft der Druckfeder 14 aufnehmen, so daß die Spannschrauben leicht von Hand zurückgedreht werden können, um sodann die Spannschienen durch Verschwenken des Hebelwerkzeuges, von den Druckfedern 14 unterstützt, in ihre Ausgangsposition gleiten zu lassen, damit eine neue Druckplatte eingespannt werden kann.On the tensioning rail 4 for the trailing plate end 11, plug openings 17 are provided, which are advantageously arranged on a flat body 18, which in turn is fastened to the tensioning rail 4 by means of a screw 19. In alignment with the plug openings 17, recesses 20 are provided in the base 16 of the cylinder channel 3, which are formed as bores in the exemplary embodiment shown. A lever tool 21, which can be a plug pin, can be inserted through the plug opening 17 into the recess 20, so that an independent additional force can be briefly introduced into the rear clamping rail 4 via the lever action of the plug pin. This force can now move the tensioning rail in the tensioning direction and thereby loosen a possibly glued plate end. But you can also absorb the spring force of the compression spring 14 so that the clamping screws can be easily turned back by hand, to then slide the clamping rails by pivoting the lever tool, supported by the compression springs 14, into their starting position so that a new pressure plate can be clamped can.

Zwischen Stecköffnung 17 und Hebelwerkzeug 21 ist vorteilhaft ein Spiel vorgesehen, um eine Bewegung des Hebelwerkzeugs 21 seitlich und in Umfangsrichtung zu ermöglichen, so daß hierdurch auch die seitliche Ausrichtung der Spannschiene 4 vorgenommen werden kann. Hierbei kann an dieser eine Raststellung vorgesehen sein, die z. B. in Form einer an sich bekannten Kugelraste 22 ausgebildet sein kann, so daß beim Einlegen einer neuen Druckplatte die Spannschiene 4 auch seitlich in einer Ausgangsstellung steht. Die Spannschrauben 12 lassen sich zum einfacheren Handhaben mit einer Rändelung 23 versehen. Die Flachkörper 18 und die Spannschrauben 12 lassen sich durch entsprechende Farbgebung optisch hervorheben, so daß die Arbeit der Bedienungsperson erleichtert wird. Selbstverständlich ist auch die Länge des Hebelwerkzeugs 21 so ausgeführt, daß eine leichte Handhabung möglich ist. Durch die erfindungsgemäße Ausbildung ist somit nur noch ein Umsetzen des Werkzeuges für die Spannschrauben 12 beim Aufspannen einer neuen Druckplatte erforderlich, so daß die Zeit für das Entnehmen der Druckplatten und das Einlegen einer neuen Platte wesentlich verkürzt wird.A play is advantageously provided between the plug-in opening 17 and the lever tool 21 in order to enable the lever tool 21 to move laterally and in the circumferential direction, so that this also results in the lateral alignment of the instep rail 4 can be made. Here, a latching position can be provided on this, the z. B. in the form of a known ball catch 22, so that when inserting a new pressure plate, the tensioning rail 4 is also laterally in an initial position. The clamping screws 12 can be provided with knurling 23 for easier handling. The flat body 18 and the clamping screws 12 can be optically highlighted by appropriate coloring, so that the work of the operator is facilitated. Of course, the length of the lever tool 21 is also designed so that easy handling is possible. Due to the design according to the invention, only a conversion of the tool for the clamping screws 12 is required when clamping a new printing plate, so that the time for removing the printing plates and inserting a new plate is significantly reduced.
