Abstract
Description
Die Erfindung bezieht sich auf eine Einrichtung zum Wechseln von Druckformen an einem Druckformzylinder im Druckwerk einer Rotationsdruckmaschine, wobei an einem Druckwerk eine Halteeinrichtung vorgesehen ist, in der sowohl mindestens eine zuzuführende Druckform aufgenommen ist, als auch eine auszuwechselnde Druckform aufnehmbar ist.The invention relates to a device for changing printing forms on a printing form cylinder in the printing unit of a rotary printing press, wherein a holding device is provided on a printing unit, in which both at least one printing form to be fed is received and a printing form to be replaced can be received.
Aus dem Stande der Technik sind bereits Druckformwechseleinrichtungen bekanntgeworden, so beispielsweise aus EP 0 503 750 A1. Bei dieser Konstruktion sind an einem Druckwerkschutz Haltemittel für Druckformen vorgesehen, die eine Hinterkante einer zu montierenden Druckform während deren Aufzug auf den Druckformzylinder halten.Printing form changing devices have already become known from the prior art, for example from EP 0 503 750 A1. In this construction, holding means for printing forms are provided on a printing unit guard, which hold a trailing edge of a printing form to be assembled while it is being lifted onto the printing form cylinder.
EP 0 530 565 A1 offenbart ein Magazin für den automatischen Druckplattenwechsel. In dem Magazin können für den Plattenwechsel mehrere Druckplatten dadurch bereitgestellt werden, daß in das Magazin eine Kassette einschiebbar ist, die ihrerseits mehrere Druckplatten aufnimmt. Je nach Bedarf sind diese durch die Plattenzufuhreinrichtung entnehmbar.EP 0 530 565 A1 discloses a magazine for the automatic printing plate change. A plurality of printing plates can be provided in the magazine for the plate change by inserting a cassette into the magazine, which in turn holds several printing plates. Depending on requirements, these can be removed through the plate feed device.
EP 0 567 754 A1 zeigt eine Vorrichtung zum Zuführen einer Druckplatte zu einem Plattenzylinder einer Druckmaschine.EP 0 567 754 A1 shows a device for feeding a printing plate to a plate cylinder of a printing press.
Bei dieser Vorrichtung wird eine Schonung der druckenden Fläche einer Druckform dadurch erreicht, daß zum Halten und Führen der Druckform mindestens eine leicht drehbare Rolle vorgesehen ist. Die dem Druckwerk zugewandte Seite der Rolle liegt in einer Plattenwechselposition im wesentlichen auf einer Geraden, die parallel zu den Klemmflächen der Einrichtung zur Aufnahme der Druckplattenvorderkante verlaufend zwischen diesen Klemmflächen hindurchführt und schräg nach oben aus dem Druckwerk herausführt. Neben der Rolle als Führungselement kann auch ein Saugnapf vorgesehen sein.In this device, protection of the printing surface of a printing form is achieved in that at least one easily rotatable roller is provided for holding and guiding the printing form. The side of the roll facing the printing unit lies in a plate changing position essentially on a straight line which runs parallel to the clamping surfaces of the device for receiving the printing plate leading edge between these clamping surfaces and leads out obliquely upwards from the printing unit. In addition to the role as a guide element, a suction cup can also be provided.
EP 0 570 702 A1 schließlich, offenbart eine Vorrichtung zum Zuführen von Druckplatten auf den Plattenzylinder von Druckmaschinen, insbesondere Bogendruckmaschinen. Ein in einer Führungsschiene am Druckwerk bewegbares Schutz umfaßt ein leicht gekrümmtes Blechprofil. Das Blechprofil seinerseits weist eine Einführschiene auf, welche die Vorderkante der jeweils zuzuführenden Druckform direkt in den Erfassungsbereich der Spanneinrichtungen des Druckformzylinders einführt.Finally, EP 0 570 702 A1 discloses a device for feeding printing plates onto the plate cylinder of printing machines, in particular sheet-fed printing machines. A protection that can be moved in a guide rail on the printing unit comprises a slightly curved sheet metal profile. The sheet metal profile in turn has an insertion rail, which introduces the front edge of the printing form to be fed directly into the detection area of the clamping devices of the printing form cylinder.
Den aufgezeigten Lösungen des Standes der Technik haftet durchweg der Nachteil an, daß viele bewegte Teile erforderlich sind, die zum Teil, selbst wenn sie nicht benötigt sind, den Zugang zum Druckwerk zumindest einschränken. Ferner ist bei den aufgezeigten Lösungen zum Teil nicht immer gewährleistet, daß die druckende Fläche der jeweiligen Druckformen weitgehend geschont werden.The solutions of the prior art shown have the disadvantage that many moving parts are required, some of which, even if they are not required, at least restrict access to the printing unit. Furthermore, the solutions shown do not always guarantee that the printing surface of the respective printing forms is largely protected.
Der Erfindung liegt daher die Aufgabe zugrunde, eine Einrichtung zum Druckformwechsel so zu verbessern, daß über die Druckwerkbreite gesehen, bei Betrieb des Druckwerkes möglichst wenige Teile im Zugangsbereich des Druckers verbleiben, so daß das Druckwerk möglichst ungehindert zugänglich bleibt.The invention is therefore based on the object of improving a device for changing the printing form in such a way that, viewed across the printing unit width, as few parts as possible remain in the access area of the printer during operation of the printing unit, so that the printing unit remains accessible as freely as possible.
Erfindungsgemäß wird diese Aufgabe durch die Merkmale des Patentanspruches 1 gelöst.According to the invention, this object is achieved by the features of
Die mit der erfindungsgemäßen Lösung erzielbaren Vorteile liegen unter anderem darin, daß die druckenden Flächen der Druckformen nicht berührt werden. Die Führung der Druckformen in den seitlich angeordneten Profilkörpern gewährleistet, daß nach Aufzug der Druckform auf den Umfang des Druckformzylinders kein Bauteil mehr im Arbeitsbereich am jeweiligen Druckwerk verbleibt. Der Drucker hat nunmehr ungehinderten Zugang zum Druckwerk - für Reinigungs- und gegebenenfalls für Wartungsarbeiten.The advantages that can be achieved with the solution according to the invention include the fact that the printing surfaces of the printing forms are not touched. The guidance of the printing forms in the laterally arranged profile bodies ensures that after the printing form has been lifted to the circumference of the printing form cylinder, no component remains in the work area on the respective printing unit. The printer now has unhindered access to the printing unit - for cleaning and, if necessary, for maintenance work.
In weiterer Ausgestaltung der erfindungsgemäßen Lösung können die Profilkörper sowohl stationär an Seitenwänden des Druckwerkes als auch an den Seitenwänden verschwenkbar aufgenommen werden. Die Profilkörper sind vorteilhafterweise jeweils mit Ausnehmungen versehen, durch welche die Seitenbereiche der Druckformen umfaßt werden und die somit als Führung dienen. Die Ausnehmungen können in den Profilkörpern mäanderförmig - vorzugsweise S-förmig - verlaufen, so daß den jeweils aufzunehmenden Druckformen eine versteifende Verformung aufgeprägt wird, die sie gegen Vibrationen am Druckwerk unempfindlicher macht und durch welche die seitliche Führung in den Ausnehmungen ermöglicht wird.In a further embodiment of the solution according to the invention, the profile bodies can be pivotally received both in a stationary manner on side walls of the printing unit and on the side walls. The profile bodies are advantageously each provided with recesses through which the side areas of the printing forms are encompassed and which thus serve as a guide. The recesses can run in a meandering shape - preferably S-shaped - in the profile bodies, so that a stiffening deformation is impressed on the printing forms to be accommodated, which makes them less sensitive to vibrations on the printing unit and by which lateral guidance in the recesses is made possible.
Die Profilkörper umfassen ferner Antriebseinheiten und zwar jeweils für die zuzuführende erste Druckform, wie für die zu entnehmende zweite Druckform. Die Antriebseinheiten - beispielsweise kompakte Elektromotoren mit Friktionsrollen - arbeiten mit Stützelementen zusammen, so daß die Seitenbereiche beidseits der Druckformen reibschlüssig gefördert werden können. Die erwähnten Stützelemente können sowohl als Rollen oder auch bänderförmig ausgeführt sein. Im Bereich der Antriebseinheiten an den jeweiligen Ausnehmungen am Profilkörper werden die Seitenbereiche geführt.The profile bodies further comprise drive units, specifically for the first printing form to be fed, as well as for the second printing form to be removed. The drive units - for example compact electric motors with friction rollers - work together with support elements so that the side areas on both sides of the printing form can be conveyed in a frictional manner. The support elements mentioned can be designed both as rollers or as a strip. The side areas are guided in the area of the drive units on the respective recesses on the profile body.
Anhand einer Zeichnung sei die Erfindung nachstehend näher erläutert.The invention is explained in more detail below with reference to a drawing.

In der Darstellung gemäß Fig. 1 ist die erfindungsgemäße Lösung an einem oberen Druckformzylinder 3 eines Druckwerkes 1 gezeigt. Bei einem eine Bahn beidseitig bedruckenden Druckwerk kann die erfindungsgemäße Einrichtung ohne weiteres auch am unteren der Druckformzylinder vorgesehen werden.1, the solution according to the invention is shown on an upper
An den beiden Seitenwänden 2 eines Druckwerkes 1 sind jeweils Profilkörper 9 befestigt. Diese Profilkörper 9 enthalten jeweils mindestens eine erste Druckform 4 - die neu auf einen Druckformzylinder 3 des Druckwerkes 1 aufgebracht wird - sowie mindestens eine zweite Druckform 5, die zuvor vom Druckformzylinder 3 abgenommen worden ist. Die Druckformen 4 und 5 weisen jeweils Druckformvorderkanten 7 sowie Druckformhinterkanten 8 auf, die in Klemmeinrichtungen auf dem Umfang des Druckformzylinders 3 eingeführt werden und die Druckformen 4 bzw. 5 auf dem Umfang des Druckformzylinders 3 fixieren. Die Seitenbereiche 6 (siehe Fig. 2) der Druckformen werden in Profilen 10, 11 an oder innerhalb der Profilkörper 9 geführt. Die Profile 10, 11 zur Aufnahme der Seitenbereiche 6 der Druckformen 4, 5 sind als Ausnehmungen 12, 13 ausgeführt, die mäanderförmig gekrümmt an oder innerhalb der Profilkörper 9 verlaufen. Vorzugsweise weisen die Ausnehmungen eine S-förmige Krümmung auf. Mittels der den Druckformen 4 und 5 durch die Ausnehmungen 12, 13 aufgeprägte Krümmung werden die Druckformen 4, 5 derart versteift, daß deren Führung nur an den Seitenbereichen 6 völlig ausreichend ist. Daher sind keine Führungshilfen notwendig, die auf die druckende Oberfläche der Druckformen 4 und 5 einwirken, wodurch die Beschädigungsgefahr der empfindlichen Oberflächen drastisch gemindert wird.
An den Profilen 10, 11 der Profilkörper 9 sind Antriebseinheiten 14 vorgesehen. Diese Antriebseinheiten 14 arbeiten mit Stützelementen 15 zusammen, die im Ausführungsbeispiel als Rollen dargestellt sind. Bänder oder Kunststoffketten wären ebenfalls denkbar.
Aus Fig. 2 geht die Konfiguration des Antriebs an den Profilkörper detaillierter hervor.2 shows the configuration of the drive on the profile body in more detail.
An den Profilkörpern 9, die durch eine Befestigung 17 mit der jeweiligen Seitenwand verbunden sein können, aber auch verschwenkbar sein könnten, befinden sich die Antriebe 14, die Friktionsrollen 14.1 umfassen. Aus Symmetriegründen ist nur eine Hälfte des Druckwerkes bis zur Maschinenmitte 16 gezeigt. Die Friktionsrollen 14.1 arbeiten mit Stützelementen 15 zusammen, die unterhalb der Friktionsrolle 14.1 vorgesehen sind. Die Friktionsrolle 14.1 und das Stützelement 15 ergreifen den Seitenbereich 6 der Druckform 4 beidseitig und fördern die Druckform 4 auf den Umfang des hier nicht dargestellten Druckformzylinders 3. Um einen einwandfreien Transport der Druckformen 4, 5 - also der zuzuführenden wie der zu entnehmenden Druckform - zu gewährleisten, ist der gezeigten Antriebseinheit 14 eine entsprechende an der - hier nicht gezeigten - gegenüberliegenden Seitenwand 2 des Druckwerkes zugeordnet.The
Jeder sich in den Profilkörper 9 erstreckenden Ausnehmung 12, 13 ist mindestens eine Antriebseinheit 14 zugeordnet. Es können durchaus auch mehrere Antriebseinheiten 14 entlang des Förderpfades der jeweiligen Druckformen 4 und 5 vorgesehen sein. Es kann dahingestellt bleiben, ob die Ausnehmungen 12, 13 unmittelbar in den Profilkörpern 9 vorgesehen sind, oder ob separate U-förmige Profile an den Profilkörpern 9 befestigt werden können. Die in Fig. 2 dargestellten Antriebseinheiten 14 befinden sich ebenfalls entlang des Förderpfades für die zweite, die zu entnehmende Druckform 5, auch wenn dies in Fig. 2 nicht dargestellt ist. Durch die dargestellten Friktionsrollen 14.1, die mit dem Stützelement 15 zusammenwirken, lassen sich die Bereiche 6 der Druckformen 4, 5 etwa mittig in den Querschnitt der Ausnehmungen 12, 13 führen, so daß ein Schleifen auf den Oberflächen der Ausnehmungen 12, 13 wirksam verhindert werden kann.Each
Es wäre jedoch auch denkbar, kleinere Druckformen 4, 5 in jeweils geradlinig verlaufenden Ausnehmungen 12, 13 zu führen. Kleinere Druckformen 4, 5 haben aufgrund ihrer kleineren Abmessungen eine erhöhte Steifigkeit, wodurch eine eine Versteifung herbeiführende Verformung der kleineren Druckformen 4, 5 bei deren Zufuhr unterbleiben kann.However, it would also be conceivable to guide
