Abstract
Description
Die Neuerung betrifft eine Vorrichtung nach dem Oberbegriff des Anspruches 1.The Innovation relates to a device according to the preamble of the claim 1.
Es ist bekannt im Bereich der Bogentransporteinrichtungen zwischen den Druckwerken einer Druckmaschine und einer Auslegeeinrichtung Inspektionssysteme anzuordnen. Hierbei werden Kameras oder Detektionssysteme den bogenführenden Elementen wie endlosen Kettenfördersystemen oder Bogentransporttrommeln zugeordnet. Nach dem wie die Bogen bedruckt sind werden die Inspektionssysteme sowohl der Bogenvorderkante als auch der Bogenrückseite zugeordnet. Hierbei ist es notwendig, die Bogen in einer definierten Lage für die Abtastung bereitzustellen. Hierzu sind verschiedene Möglichkeiten beschrieben worden. Einerseits kann ein Bogen an einem Kettenfördersystem geführt werden und in diesem Fall in einer geraden Strecke ausgespannt werden.It is well known in the field of sheet transport facilities between the printing units of a printing press and a delivery device To arrange inspection systems. These are cameras or detection systems the sheet-guiding elements like endless chain conveyor systems or sheet transport drums assigned. After how the sheets are printed are the inspection systems of both the bow front edge and also the bow back assigned. It is necessary to have the sheets in a defined position Location for to provide the scan. There are various possibilities for this been described. On the one hand, a bow on a chain conveyor system guided be stretched out and in this case in a straight stretch.
Eine
derartige Vorrichtung mit einem Inspektionssystem an Druckmaschinen
ist in der
Eine andere Möglichkeit ergibt sich darin, dass in einer Druckmaschine bedruckten Bögen während des Bogentransportes auf einer Bogentransporttrommel vermessen werden. Hierbei kann vorgesehen sein, die Druckbögen mittels pneumati scher Mittel auf der Bogentransporttrommel straft zu halten. Mittels einer der Bogentransporttrommel zugeordneten Aufnahmeeinrichtung kann der Bogen dann in definierter Lage vermessen werden.A different possibility This results in printed sheets printed in a printing machine during the printing process Sheet transport on a sheet transport drum to be measured. It can be provided, the signatures by means of pneumatic shear means to punish the sheet transport drum. By means of one of The sheet transport drum associated receiving device, the Bow then be measured in a defined position.
Eine
derartige Vorrichtung ist in der
Weiterhin ist in der DE 10 2005 011 758 A1 eine Bogenleiteinrichtung in einer Bogendruckmaschine in Verbindung mit einer Bogeninspektionseinrichtung beschrieben.Farther is in DE 10 2005 011 758 A1 a sheet guiding device in one Sheet-fed printing press in conjunction with an arc inspection device described.
Diese Einrichtung weist ebenfalls noch Lücken im Leitbereich auf, an denen die Druckbogen beschädigt werden oder an denen sich Druckfarbe von den Druckbogen ablegen kann.These The device also still has gaps in the guidance area which damaged the printed sheets or where ink is deposited from the sheets can.
Die Aufgabe der Erfindung ist daher, in einer gattungsgemäßen Vorrichtung die Bogenführung für die exakte Abtastung der Druckbögen auf einfache Weise zu verbessern und die Abtastung innerhalb des Bogenlaufes einer Druckmaschine ohne zusätzlichen konstruktiven Aufwand zu ermöglichen.The The object of the invention is therefore, in a generic device the bowing for the exact scanning of the signatures to easily improve and the scanning within the Sheet running a printing press without additional design effort to enable.
Die gestellte Aufgabe wird gelöst mit den Merkmalen des Anspruches 1.The Asked task is solved with the features of claim 1.
In vorteilhafter Weise wird durch den Einsatz einer einfachen Bogenführungseinrichtung im Bereich nach dem Druckspalt des letzten Druckwerkes an dem entsprechenden letzten Druckzylinder eine Verbesserung der Abtastbarkeit von Bogen erzielt. Gleichzeitig kann in diesem Bereich die Bogenabtastung ohne weitere Probleme ausgeführt werden.In Advantageously, by the use of a simple sheet guiding device in the area after the nip of the last printing unit to the corresponding Last printing cylinder an improvement in the scanning of sheets achieved. At the same time in this area the arc scan executed without further problems become.
In vorteilhafter Weise kann die Bogenführung in Form einer transparenten Leitanordnung ausgebildet sein. Hierzu kann ein verschleißfestes Glas verwendet werden, das eine ungehinderte Sicht auf den zu inspizierenden Bogen gestattet. In weiterer Ausgestaltung kann das transparente Leitelement zwischen einsetzbaren Bogenleiteinrichtungen einspannbar vorgesehen sein.In Advantageously, the sheet guide in the form of a transparent Guiding arrangement to be formed. For this purpose, a wear-resistant Glass used, which gives an unobstructed view of the inspected Bow allowed. In a further embodiment, the transparent Guide element between insertable sheet guiding devices clamped be provided.
Weiterhin kann in einer Ausgestaltung der Erfindung die Glasplatte mit einer farbabweisenden Oberfläche versehen sein, so dass die Abtastung der Bogen jederzeit ohne Probleme möglich ist.Farther In one embodiment of the invention, the glass plate with a color-repellent surface Be provided so that the scanning of the bow at any time without problems possible is.
Die Erfindung wird im Folgenden anhand eines Ausführungsbeispieles näher dargestellt. Die zugehörigen Zeichnungen zeigen inThe Invention will be described in more detail below with reference to an embodiment. The associated Drawings show in
