Description
Die Erfindung bezieht sich auf eine Bogenoffset-Rotationsdruckmaschine mit Druckwerken zum mehrfarbigen Bedrucken von Bogen auf einer Bogenseite oder im Schön- und Widerdruck und einem Anleger für die den Druckwerken zuzuführenden Bogen sowie mit einem den Farbdruckwerken vorgeschalteten Druck- oder Veredelungswerk, insbesondere auf eine derartige Druckmaschine, bei der mehrere den Bogen von oben bedruckende Farbdruckwerke in Laufrichtung des Bogens in Reihe hintereinander angeordnet sind.The invention relates to a sheet-fed rotary printing press with printing units for multi-color printing of sheets on a sheet side or in face and reverse printing and a feeder for the sheets to be fed to the printing units, and with a printing or finishing unit upstream of the color printing units, in particular to such a printing machine , in which several color printing units printing the sheet from above are arranged in series in the running direction of the sheet.
Entsprechend ausgebildete Bogenoffset-Rotationsdruckmaschinen mit mehreren Druckwerken in Reihenbauart für die Herstellung mehrfarbiger Drucke im Schöndruck und im Schön- und Widerdruck sind aus den DE-OS 34 19 762 und 37 17 093 bekannt.Correspondingly trained sheet-fed rotary printing presses with several printing units in series for the production of multicolored prints in straight printing and in face and back printing are known from DE-OS 34 19 762 and 37 17 093.
Bei der Maschine nach der DE-OS 34 19 762 ist eine Wendeeinrichtung zwischen zwei Druckwerken vorgesehen, wobei überführungszylinder den aus einem vorhergehenden Farbdruckwerk ankommenden Bogen aufnehmen und einem sich daran anschließenden Wendezylinder mit Zangengreifern zuführt, die in einer Kanalausnehmung angeordnet sind und den zunächst an der Stelle des geringsten Abstandes beider Zylinder voneinander vorbeilaufenden Bogen an dessen Hinterkante erfassen und dann mit der Hinterkante voraus dem nächsten Druckwerk zuführen, so daß dadurch eine Wendung des Bogens erfolgt.In the machine according to DE-OS 34 19 762, a turning device is provided between two printing units, transfer cylinders receiving the sheet arriving from a previous color printing unit and feeding a subsequent turning cylinder with pliers grippers which are arranged in a channel recess and which are initially on the Detect the point of the smallest distance between the two cylinders of the sheet running past each other at its rear edge and then feed it to the next printing unit with the rear edge ahead, so that the sheet is turned.
Die DE-OS 37 17 093 offenbart eine andere Bauart einer Wendeeinrichtung zwischen Druckwerken einer Bogenoffset-Rotationsdruckmaschine für den mehrfarbigen Druck. Hiernach ist einem Bogenübergabezylinder, der den Bogen von einem vorausgehenden Druckwerk übernimmt, ein Bogenauflager nachgeordnet, welches eine im wesentlichen flache und etwa tangential zum Umfang des Bogenübergabezylinders gestaltete Auflageroberseite aufweist, auf welcher der Bogenübergabezylinder den Bogen während der Annäherung seiner die Bogenhinterkante haltenden Greifer mit der freien Bogenvorderkante voraus aufschiebt und von welcher der Bogen vom Bogenübergabezylinder mit der Bogenhinterkante voraus gerichtet abgehoben wird, um auf diese Weise ebenfalls eine Wendung des Bogens zu bewirken. Das Bogenauflager kann fest oder als ein umlaufendes Band ausgebildet sein. Die anfängliche Herstellung des Widerdruckes und die anschließende Erstellung des Schöndruckes mit solchen Druckmaschinen ist praktizierter Stand der Technik.DE-OS 37 17 093 discloses another design of a turning device between printing units of a sheet-fed offset rotary printing press for the multi-colored Print. According to this, a sheet transfer cylinder, which takes over the sheet from a preceding printing unit, is followed by a sheet support, which has a substantially flat and approximately tangential to the circumference of the sheet transfer cylinder support top, on which the sheet transfer cylinder the sheet while the gripper holding the sheet trailing edge with the pushes open the leading edge of the sheet ahead and from which the sheet is lifted from the sheet transfer cylinder with the sheet trailing edge facing in front, in order to also bring about a turn of the sheet in this way. The sheet support can be fixed or designed as a circumferential band. The initial production of the counterprint and the subsequent creation of the face print with such printing presses is state of the art.
Bekannt ist es auch, den Druckwerken einer Bogenoffset-Rotationsdruckmaschine für den mehrfarbigen Druck ein Druckwerk zum Bedrucken der Bogenrückseite vorzuschalten. Solche Druckwerke sind fest angeordnet und liegen auf der Bogenunterseite, so daß sie von unten gegen den anschließend in das erste Druckwerk einlaufenden Bogen wirksam sind.It is also known to precede the printing units of a sheet-fed offset rotary printing machine for multicolor printing with a printing unit for printing on the back of the sheet. Such printing units are fixed and lie on the underside of the sheet, so that they are effective from below against the sheet subsequently entering the first printing unit.
Von unten wirksame, unter dem Anlegetisch angeordnete Zusatzdruckwerke sind in der Bedienung ungünstig und ergeben eine reduzierte Druckqualität.Additional printing units that are effective from below and are arranged under the feed table are unfavorable to operate and result in reduced print quality.
Falls Bogen, insbesondere bereits vorbearbeitete Bogen, mit der Oberseite unten im Stapel liegen und dadurch an Vorder- und Hinterkante hochstehen, ist zur Sicherung des Papierlaufs im Anleger eine Stapelwendung in einem gesonderten Stapelwender erforderlich.If sheets, in particular sheets that have already been pre-processed, lie with the top side in the bottom of the stack and thus stand up at the front and rear edges, a stacking turn in a separate stacking turner is required to secure the paper run in the feeder.
Aus der JP-Sho 59-192336 ist eine Bogenoffset-Rotationsdruckmaschine bekannt, bei der den Druckwerken einer Mehrfarben-Druckmaschine eine Wendeeinrichtung vorgeschaltet ist, um den zu bedruckenden Bogen gegebenenfalls vor dem Einlauf in das erste Druckwerk wenden zu können.From JP-Sho 59-192336 a sheet-fed rotary printing press is known, in which the printing units of a multicolour printing press Turning device is connected upstream in order to be able to turn the sheet to be printed, if necessary, before it enters the first printing unit.
Aufgabe der Erfindung ist die Gestaltung einer variabel einsetzbaren Bogenoffset-Rotationsdruckmaschine in Reihenbauart zum abschmierfreien Bedrucken von Karton und Papier im mehrfarbigen Schön- und Widerdruck mit hoher Offset-Druckqualität und einer sicheren Verarbeitung der Bogen im Anleger.The object of the invention is the design of a variably usable sheet-fed rotary printing press in a row design for the smudge-free printing of cardboard and paper in multi-color face and back printing with high offset printing quality and a safe processing of the sheets in the feeder.
Die Lösung dieser Aufgabe besteht erfindungsgemäß darin, daß eine Umstülpeinrichtung als zusätzliche Wendeeinrichtung in Laufrichtung der zu bedruckenden Bogen zwischen einem vorgeschalteten Druck- oder Veredelungswerk und den Druckwerken für den Schön- und Widerdruck angeordnet ist.The solution to this problem is, according to the invention, that an everting device is arranged as an additional turning device in the running direction of the sheets to be printed between an upstream printing or finishing unit and the printing units for the perfecting.
Dadurch kann das Bedrucken von Bogen aus Karton und Papier auf der Vorder- und Rückseite mit hoher Offset-Druckqualität sehr variabel erfolgen, zum Beispiel 1:4 oder 2:3 in einer Maschine mit vier oder mehr Farbdruckwerken. Auch gekrümmte Bogen aus Karton oder dergleichen können im Anleger sicher verarbeitet werden, da sie mit der Oberseite oben im Stapel des Anlegers liegen können und durch die zusätzliche Umstülpeinrichtung zunächst gewendet werden können, bevor ihre Unterseite den Widerdruck erhält. Bei glatter (ebener) Stapellage können die über den Anleger zugeführten Bogen bei Schöndruck die abgeschaltete Umstülpeinrichtung passieren und in der bisher gewohnten Weise bearbeitet werden.As a result, the printing of sheets of cardboard and paper on the front and back with high offset print quality can be done very variably, for example 1: 4 or 2: 3 in a machine with four or more color printing units. Even curved sheets of cardboard or the like can be safely processed in the feeder, since they can lie with the top side in the stack of the feeder and can be turned over by the additional everting device before their underside receives the back pressure. In the case of a smooth (flat) stacking position, the sheets fed in via the feeder can pass through the turned-over device in the case of straight printing and can be processed in the usual manner.
Eine vorteilhafte Anwendungsmöglichkeit der Umstülpeinrichtung ergibt sich beim Bedrucken von Bogen aus Karton, deren zu bedruckende Oberfläche vor dem Druck einer Reinigungsbehandlung oder einer anderen die Oberfläche veredelnden Behandlung, zum Beispiel einer Numerierung, Prägung oder dergleichen zu unterziehen ist. Dazu wird der vom Anleger mit der Oberseite oben zugeführte Bogen zunächst einer solchen Veredelungsbearbeitung unterworfen, dann durch die Umstülpeinrichtung gewendet und der Widerdruck ausgeführt, worauf nach einer weiteren Wendung ein abschmierfreier Schöndruck auf der zuvor behandelten Oberseite des Bogens erfolgt.An advantageous application of the everting device arises in the printing of sheets of cardboard, the surface of which is to be subjected to a cleaning treatment or another treatment ennobling the surface, for example a numbering, embossing or the like, before printing. For this the the sheet fed from the feeder with the top side first subjected to such a finishing process, then turned over by the everting device and the reverse pressure is carried out, whereupon, after a further turn, a smear-free fine print is carried out on the previously treated top side of the sheet.
Von besonderem Vorteil ist die Umstülpeinrichtung als zusätzliche Wendeeinrichtung beim Aufbringen einer Unterlegfarbe für den Schöndruck. Die Umstülpeinrichtung ermöglicht das Aufbringen der Unterlegfarbe von oben, worauf die Umstülpeinrichtung den Bogen zum Widerdruck wendet, so daß nach einer abermaligen Wende der Schöndruck hergestellt werden kann.Of particular advantage is the everting device as an additional turning device when applying an underlay color for face printing. The everting device makes it possible to apply the underlay color from above, whereupon the everting device turns the sheet for reverse printing, so that after a repeated turn, the fine print can be produced.
Bogen aus stärkerem Papier und Karton können mit einem oben liegenden Eindruck- oder Veredelungswerk problemlos bearbeitet werden und danach die zusätzliche Umstülpeinrichtung passieren, so daß sie mit der Oberseite oben in die Farbdruckwerke einlaufen. Eine solche Anordnung ist somit ergonomisch besonders günstig und auch sicherheitstechnisch als vorteilhafte Lösung anzusehen.Sheets of thicker paper and cardboard can be easily processed with an imprinting or finishing unit on top and then pass through the additional inverting device, so that they run into the color printing units with the top side up. Such an arrangement is therefore ergonomically particularly favorable and can also be regarded as an advantageous solution in terms of safety.
