Abstract
Die Erfindung betrifft ein Verfahren zum Zu- und Abführen flexibler Druckplatten. Aufgabe der Erfindung ist die Schaffung eines Verfahrens zum gleichzeitigen Zu- und Abführen. Erfindungsgemäß wird die Aufgabe dadurch gelöst, dass · die Druckformzylinder (4) aus dem Antriebsräderzug ausgegliedert in eine Synchronstellung gefahren und entgegen dem Uhrzeigersinn gedreht, · vor Erreichen der Auswerfposition (22) der Aufnahmekasten (16) und die Druckplattenlöseeinrichtung (14) angestellt, in der Auswerfposition die vorderen Klemmelemente (6) gelöst, · die ersten alten Druckplatten (6) ausgefahren, · in der Zuführposition (24) die neuen ersten Druckplatten (9) zugeführt, an der Vorderkante geklemmt, die Aufbügelwalzen (13) angestellt und die Druckplatten (9) aufgebügelt, · die hinteren Klemmelemente (7) der alten ersten Druckplatten (9) geöffnet und die Druckplatten ausgeworfen, · vor Erreichen der Auswerfposition (23) die Druckplattenlöseeinrichtungen (14) angestellt und die Verfahrensschritte für die zweiten alten und neuen Druckplatten (10) wiederholt, · die neuen ersten Druckplatten (9) an der Hinterkante geklemmt, · nach Abschluß der Wiederholung der Verfahrensschritte die zweiten neuen Druckplatten (10) geklemmt, die Druckformzylinder (4) in die Druckposition verfahren und in den Antriebsräderzug der Druckmaschine eingegliedert werden.The invention relates to a method for feeding and removing flexible printing plates. The object of the invention is to provide a method for simultaneous supply and removal. According to the invention, the object is achieved in that · the printing form cylinder (4) moved out of the drive wheel train in a synchronized position and rotated counterclockwise, before reaching the ejection position (22) of the receiving box (16) and the printing plate release device (14) employed, in the ejection position, the front clamping elements (6) released, the first old printing plates (6) extended, fed in the feed position (24) the new first printing plates (9), clamped at the leading edge, the ironing rollers (13) turned on and the printing plates (9) ironed on, the rear clamping elements (7) of the old first printing plates (9) opened and the printing plates ejected, · the printing plate release devices (14) are set before reaching the ejection position (23) and the process steps for the second old and new printing plates ( 10), · the new first pressure plates (9) are clamped at the trailing edge, · after completion of the repetition of the process steps, the second new printing plates (10) clamped, the printing form cylinder (4) moved to the printing position and incorporated into the drive wheel of the printing press.
Description
Die Erfindung betrifft ein Verfahren zum Zu- und Abführen flexibler Druckplatten zu und von zwei Druckformzylindern einer Druckmaschine.The The invention relates to a method for feeding and removing flexible printing plates to and from two printing forme cylinders of a printing press.
Es
ist eine Druckmaschine in Kompaktbauweise mit einem Druckzylinder
und zwei jeweils einen Offsetzylinder und einen Druckformzylinder
mit jeweils zwei Wirkflächen
enthaltenden Zylindergruppen bekannt, wobei den Druckformzylindern
je eine Bebilderungseinrichtung zur Realisierung der Computer-to-Press
Technologie zugeordnet ist (
Unterhalb des Druckformzylinders ist ein Aufnahmekasten für ausgedruckte Druckplatten angeordnet.Below The printing forme cylinder is a receiving box for printed printing plates arranged.
Zum Abführen bedruckter Druckplatten vom mit vorderen und hinteren die Druckplatte klemmenden Klemmelementen ausgestatteten Druckformzylinder ist dem Druckformzylinder eine Druckplattenlöseeinrichtung und eine die abzuführende Druckplatte zu einem Aufnahmekasten leitende Führungseinrichtung zugeordnet.To the lead away printed printing plates from with front and back the printing plate clamped clamping elements equipped printing forme cylinder is the Printing form cylinder a printing plate release device and a dissipated Pressure plate assigned to a receiving box conductive guide device.
