Abstract
Description
Die Erfindung betrifft eine Plattenspannvorrichtung für den Plattenzylinder einer Druckmaschine gemäß dem Oberbegriff des Anspruchs 1.The The invention relates to a plate clamping device for the plate cylinder a printing press according to the preamble of claim 1.
Zur Befestigung und Verspannen von Platten an Plattenzylindern einer Druckmaschine sind z. B. als Schnellverschlüsse ausgebildete Plattenverschlüsse nach dem „barenschen" Prinzip bekannt. Durch den dort vorgesehenen Spannmechanismus wird die Druckplatte aktiv gespannt. Solche Plattenverschlüsse sind zwar aufwendig in der Herstellung und Fertigung, sie sind jedoch sehr gut geeignet für extreme Einsatzbedingungen wie z. B. große Plattenformate bzw. hohe Umfangsgeschwindigkeiten des Plattenzylinders. Das hauptsächliche Einsatzgebiet solcher Plattenverschlüsse sind Druckwerke mit Schmitzringläufern.to Fixing and clamping plates to plate cylinders Printing press are z. B. designed as snap closures plate closures after known by the "Baren" principle the clamping mechanism provided there, the pressure plate is active curious; excited. Such plate closures Although they are expensive to manufacture and manufacture, they are very suitable for extreme Operating conditions such. B. large plate formats or high Peripheral speeds of the plate cylinder. The main one Application of such plate fasteners are printing units with Schmitzringläufern.
Weiterhin sind Plattenverschlüsse mit Schlitzspannung bekannt. Beim so genannten Schlitzverschluss sind die beiden abgewinkelten Enden der Platte in den schlitzartigen Zylinderkanal des Plattenzylinders eingeführt und das vorlaufende Ende der Platte ist spitzwinkelig abgewinkelt und in den entsprechend orientierten Zylinderkanal des Plattenzylinders eingehängt. Hierbei erhält die Platte ihren Halt auf dem Plattenzylinder in Umfangsrichtung aufgrund der spitzwinkeligen Abkantung an der Vorderseite, durch die Überrollung sowie aufgrund von Unterdruckeffekten unterhalb der Druckplatten in Richtung zum Plattenzylinder.Farther are plate closures known with slot tension. When so-called slot shutter are the two angled ends of the plate in the slot-like Cylinder channel of the plate cylinder introduced and the leading end the plate is angled at an acute angle and in the corresponding hung oriented cylinder channel of the plate cylinder. in this connection receives the plate makes its grip on the plate cylinder in the circumferential direction due to the acute-angled fold on the front, through the roll over as well as due to negative pressure effects below the printing plates towards the plate cylinder.
Die Vorteile eines solchen Befestigungssystems liegen insbesondere darin, dass die Platte besonders einfach auf den Plattenzylinder aufgelegt werden kann und dass für einen solchen Schlitzverschluss nur wenige Teile benötigt werden, so dass die Fertigung einfach und kostengünstig ist. Die Nachteile eines solchen Befestigungssystems liegen jedoch darin, dass es bei hohen Umfangsgeschwindigkeiten der Plattenzylinder bzw. bei großen Formaten der Druckplatten zum Ablösen der Druckplatte vom Plattenzylinder kommen kann. Darüber hinaus findet bei diesem Befestigungssystem keine aktive Nachspannung der Platte während des Betriebes statt.The Advantages of such a fastening system are, in particular, that the plate can be very easily placed on the plate cylinder can and that for such a slit closure only a few parts are needed so that the production is easy and inexpensive. The disadvantages of a However, such fastening system is that it at high Circumferential speeds of the plate cylinder or in large formats the printing plates for detachment the pressure plate can come from the plate cylinder. In addition, finds with this fastening system no active tension of the plate while of the operation.
Der Erfindung liegt die Aufgabe zugrunde, eine Plattenspannvorrichtung für den Plattenzylinder einer Druckmaschine zu schaffen.Of the Invention is based on the object, a plate clamping device for the To provide plate cylinder of a printing press.
Die Aufgabe wird erfindungsgemäß durch die Merkmale des Anspruchs 1 gelöst.The The object is achieved by the Characteristics of claim 1 solved.
Die mit der Erfindung erzielbaren Vorteile bestehen insbesondere darin, dass über einen zentrifugalkraftbetätigten Umlenkmechanismus die Platte bei zunehmender Maschinendrehzahl entsprechend nachzuspannen.The particular advantages of the invention are that over a centrifugal-operated Deflection mechanism to re-tension the plate with increasing engine speed accordingly.
Insbesondere ist die Plattenspannvorrichtung vergleichsweise einfach aufgebaut, ein Ablösen der Platte bei großen Plattenformaten bzw. hohen Umfangsgeschwindigkeiten des Plattenzylinders kann aufgrund der form- bzw. kraftschlüssigen Befestigung beider Enden der Platten nicht mehr auftreten und während des Betriebs erfolgt eine aktive Nachspannung der Platte in Umfangsrichtung. Bei Maschinenstillstand verhält sich der vorgeschlagene Plattenverschluss bzw. Plattenspannvorrichtung ähnlich bzw. gleich wie der eingangs erörterte Schlitzverschluss nach dem Stand der Technik.Especially the plate clamping device is comparatively simple in construction, a detachment of Plate at large Plate formats or high peripheral speeds of the plate cylinder can due to the positive or non-positive attachment of both ends the plates no longer occur and occurs during operation an active tension of the plate in the circumferential direction. At machine standstill behave the proposed plate closure or plate clamping device similar or same as the one discussed at the beginning Slot closure according to the prior art.
Besonders vorteilhaft hierbei ist, dass die Platte abhängig von der Maschinendrehzahl und daher von der auftretenden Fliehkraft bzw. Zentrifugalkraft in zunehmendem Maße aktiv nachgespannt wird, so dass ansonsten auftretenden Ablösebestrebungen der Platte sicher entgegengewirkt wird.Especially advantageous here is that the plate depends on the engine speed and therefore from the occurring centrifugal force or centrifugal force increasingly is actively re-tensioned, so that otherwise occurring stripping efforts the plate is safely counteracted.
