Aufgabe der Erfindung ist es, eine Vorrichtung zu entwickeln, die eine verbesserte Führung eines Bogen bei der Übergabe zwischen zwei Greifersystemen ermöglicht.task The invention is to develop a device which has an improved Leading a bow in passing between allows two gripper systems.
Die Aufgabe wird mit einer Vorrichtung gelöst, welche die Merkmale nach Anspruch 1 aufweist. Vorteilhafte Ausgestaltungen ergeben sich aus den Unteransprüchen.The Task is solved with a device which features according to claim 1. Advantageous embodiments arise from the dependent claims.
Gemäß der Erfindung sind an Greifern eines einen Bogen übergebenden Gliedes den Bogenrand berührende Niederhalter angeordnet, die jeweils in einem Bereich neben einer Greiferfläche ragen. Die den Bogenrand berührenden Flächen der Niederhalter liegen in radialer Richtung des umlaufenden Gliedes gesehen unterhalb der Greiferauflagenhöhe bzw. unterhalb einer den Bogen stützenden Mantelfläche. Die den Bogenrand berührenden Flächen der Niederhalter können in radialer Richtung des umlaufenden Gliedes einstellbar vorgesehen sein, so dass eine Anpassung an die Steifigkeit der zu fördernden Bogen gegeben ist.According to the Invention are on grippers of a bow handed over Arranged the bow edge touching down holder each in an area next to a gripper surface protrude. The sheet edge touching surfaces of the Downholder lie in the radial direction of the rotating member Seen below the gripper pad height or below a bow-supporting lateral surface. The the Arc edge touching surfaces of the hold down can be adjusted in the radial direction of the rotating member be provided so as to adapt to the rigidity of the promotional bow is given.
Die Niederhalter verhindern, dass bei einer Bogenübergabe von einem auf ein weiteres Greifersystem der Teil des Bogenrandes, der sich im Zwischenraum zwischen zwei Greifern befindet, radial nach außen bewegt. Die Niederhalter können vorteilhaft aus einem Kunststoff bestehen und eine Biegeelastizität aufweisen, so dass sich eine leichte Bauweise der Niederhalter ergibt. Durch die Niederhalter, die im Zwischenraum zwischen Greifern starr oder glatt bzw. verschiebbar angeordnet sind, wird auf den Bogenrand eine radial nach innen wirkende Kraft ausgeübt. Der Bogenrand wird reproduzierbar in einer radialen Vorzugsposition gehalten, wodurch die Genauigkeit der Bogenübergabe gesichert ist.The Hold-downs prevent from bowing one on another gripper system of the part of the sheet edge, the is located in the space between two grippers, radially moved outside. The hold downs can be beneficial consist of a plastic and a bending elasticity have, so that there is a lightweight construction of the hold-down. By the hold-down, which is rigid in the space between grippers or are arranged smoothly or slidably, is on the sheet edge exerted a radially inward force. The bow edge is reproducibly held in a radial preferred position, whereby the accuracy of the sheet transfer is secured.
Für den Fall, dass eine Krafteinwirkung auf den Bogenrand nicht erforderlich ist, können die Niederhalter abnehmbar vorgesehen werden oder aus einer Arbeitsposition in eine Ruheposition bewegt werden. Das Außerbetriebsetzen der Niederhalter kann vorgenommen werden, wenn am Bogenrand ein großer druckfreier Rand oder eine homogene Farbbelegung vorhanden ist oder wenn biegesteife Bogen gefördert werden. Es ist weiterhin möglich, die Niederhalter nur in ausgewählten Bereichen in Arbeitsposition zu bringen. Besagte Bereiche ergeben sich aus dem Druckbild und/oder der Bogenbreite.For the case that a force on the sheet edge is not required is, the hold-down can be provided detachable or moved from a working position to a rest position. The shutdown of the holddown can be made be if at the sheet edge a large pressure-free edge or a homogeneous color assignment is present or if rigid bow be encouraged. It is still possible, the hold-down to bring into working position only in selected areas. Said ranges arise from the printed image and / or the sheet width.
Die Niederhalter können von Hand oder motorisch zwischen der Arbeitsposition und der Ruheposition verstellt werden.The Hold downs can be done by hand or by motor between the Working position and the rest position are adjusted.
Der Begriff Bogen bezeichnet sowohl einzelne Blätter, als auch Falz- oder Falzprodukte und miteinander verbundene Blätter aus Papier, Kunststoff oder Metall. Drucktechnische Maschinen sind Druckmaschinen einschließlich Anleger und Ausleger, Maschinen zur Durchführung von Verfahren der Druckvor- und nachverarbeitung, Sortierer, Stapelvorrichtungen und Inspektionsvorrichtungen. Die Erfindung ist bei allen bogenführenden Zylindern bzw. Trommeln einsetzbar.Of the Term bow refers to both single leaves, as well Folded or folded products and interconnected sheets made of paper, plastic or metal. Printing machines are Printing machines including jib and jib, machines for carrying out processes of prepress and post-processing, Sorters, stackers and inspection devices. The Invention is in all sheet-guiding cylinders or drums used.
