Vorrichtungen zur Probebogenentnahme sind allgemein bekannt. In der DE 195 16 132 C2 wird eine solche Vorrichtung prinzipiell beschrieben. Diese Vorrichtungen weisen über die maximale Formatbreite verteilt angeordnete, die Stapelvorderkante bildende Vorderanschläge auf. Im Be reich der Vorderanschläge sind verteilt über die Formatbreite Bogenhalter vorgesehen, die mit Hilfsanschlägen versehen sind und entgegen der Bogenförderrichtung in den Bereich des Aus legerstapels verbracht werden können. Weiterhin ist den Hilfsanschlägen eine die Lage der Vor derkante der an den Hilfsanschlägen anzulegenden Bogen erfassende Überschießbogenkon trolle vorgesehen.Devices for taking test sheets are generally known. DE 195 16 132 C2 described such a device in principle. These devices have the maximum The width of the format is distributed across front stops forming the front edge of the stack. In Be rich of the front stops are provided across the format width sheet holder that with Auxiliary stops are provided and against the sheet conveying direction in the area of the off layer stacks can be spent. Furthermore, the auxiliary stops is the location of the front the edge of the overshoot cone to be applied to the auxiliary stops trolls provided.
Zur Entnahme eines Probebogens werden die Bogenhalter entgegen der Bogenförderrichtung in den Bereich zwischen der Oberseite des Auslegerstapels und den Kettenkreis verbracht und damit die von den Greifern geförderten Bogen mit der Vorderkante an den Hilfsanschlägen und mit dem vorderen Bereich auf den Bogenhaltern abgelegt. Mit der Überschießbogenkontrolle wird die Maschine stillgesetzt, wenn ein abzulegender Bogen über die Hilfsanschläge hinaus gefördert wird. Gleichzeitig mit dem Verbringen der Bogenhalter in den Auslegerstapelbereich werden die Vorderanschläge abgeschwenkt und der oberste Bogen des Auslegerstapels kann entnommen werden.To remove a sample sheet, the sheet holders are turned in the opposite direction to the sheet the area between the top of the boom stack and the chain circle is placed and so that the sheets conveyed by the grippers with the leading edge at the auxiliary stops and placed with the front area on the bow holders. With the overshoot bow control the machine is stopped if a sheet to be deposited extends beyond the auxiliary stops is promoted. At the same time as the sheet holder is brought into the delivery stack area the front stops are swung down and the top sheet of the boom stack can be removed.
Für die Umsetzung hoher Maschinengeschwindigkeiten ist es erforderlich, im Bogenausleger geringe Bogenfallhöhen zu realisieren. Das bedeutet, daß der Abstand zwischen der Oberseite des Auslegerstapels und der Bahn der Greifersysteme klein gehalten wird. In diesem gering gehaltenen Abstand werden zusätzlich die Anschläge für die Probebogenentnahme und Über schießbogenkontrolle positioniert, so daß der Abstand zur Bahn der Greifer weiter verringert wird. For the implementation of high machine speeds it is necessary in the sheet delivery to realize low bow heights. That means the distance between the top of the boom stack and the path of the gripper systems is kept small. In this low The distance for the sample sheet removal and over are also kept Shooting bow control positioned so that the distance to the path of the gripper is further reduced becomes.
Spricht nun bei einem Überschießbogen die Überschießbogenkontrolle an, wird die Maschine durch "Not-Aus" stillgesetzt. Das bedeutet aber, daß bis zur tatsächlichen Beendigung der Bo genzufuhr noch eine Anzahl Bogen zugeführt wird, wodurch es bei Knautschbogen und/oder bei steifen Bedruckstoffen zu Beschädigungen der Greifer und damit zu Produktivitätsverlusten kommen kann.If the overshoot bow control now responds to an overshoot bow, the machine will stopped by "emergency stop". However, this means that until the Bo Genzufuhr still a number of sheets is fed, making it in crumple and / or at stiff substrates to damage the grippers and thus to loss of productivity can come.
Aufgabe der Erfindung ist es, eine Vorrichtung zum Schutz der Greifersysteme zu schaffen, mit der eine Beschädigung der Greifersysteme bei Ansprechen der Überschießbogenkontrolle sie cher ausgeschlossen werden kann.The object of the invention is to provide a device for protecting the gripper systems damage to the gripper systems when the overshoot bow control responds can be excluded.
