Description

Die Erfindung betrifft eine Vorrichtung zum schneilen und kantengenauen Ablegen von Bogen in Druckmaschinen, insbesondere Druckmaschinen mit Tiefstapelauslage. The invention relates to a device for snowing and exact-edged depositing of sheets in printing machines, in particular printing machines with deep pile delivery.

Um die bedruckten Bogen auf dem Auslegerstapel kantengenau ablegen zu können, ist es erforderlich, daß die Bogen beruhigt über den Auslegerstapel angeliefert werden. Bei hohen Maschinengeschwindigkeiten bildet sich unterhalb des Bogens ein Luftpolster, welches erstens den Bogen zum Flattern bringt und zweitens den Bogen trägt. Dieses Luftpolster verhindert auch, daß sich der Bogen schnell auf dem Stapel ablegen kann. Speziell bei großformatigen Bogendruckmaschinen sind zur Beseitigung dieser Mangel aufwendige Einrichtungen geschaffen worden, die als allgemein bekannt anzusehen sind, so daß hier nicht näher darauf eingegangen werden muß.In order to be able to store the printed sheets on the delivery stack with precise edges, it is necessary that the sheets are delivered calmly via the delivery stack. Forms at high machine speeds There is an air cushion below the arch, which firstly causes the arch to flutter and secondly the Bow carries. This air cushion also prevents the sheet from quickly being deposited on the stack. In the case of large-format sheet-fed printing machines in particular, complex devices are required to eliminate this deficiency have been created, which are to be regarded as generally known, so that will not be discussed in more detail here must become.

Für Druckmaschinen für kleinformatige Arbeiten und solchen mit einer Tiefstapelauslage wären diese bekannten Vorrichtungen zu aufwendig und auch zu groß, so daß eine simplere Vorrichtung, die den gleichen Zweck erfüllt, wünschenswert ist.These would be known for printing machines for small-format work and those with a low pile delivery Devices too complex and too big, so that a simpler device, the same Purpose fulfilled, is desirable.

Es ist daher Aufgabe der Erfindung eine billig herzustellende und raumsparende Vorrichtung zu schaffen, die den ankommenden Bogen, bevor dieser auf dem Auslegerstapel abgelegt wird, beruhigt und das sich unter dem Bogen befindliche Luftpolster entfernt. Gleichzeitig soll auch der Bogen etwas abgebremst werden.It is therefore the object of the invention to provide a space-saving device that is inexpensive to manufacture, which calms the incoming sheet before it is deposited on the delivery stack and which is below Removed air cushions from the bow. At the same time, the bow should also be slowed down a little.

Diese Aufgabe wird durch den kennzeichnenden Teil des Anspruches 1 gelöst.This problem is solved by the characterizing part of claim 1.

Der Vorteil dieser Vorrichtung liegt darin, daß dieses Leitblech billig und einfach herzustellen ist und aufgrund seines Aufbaues in der Maschine wenig Platz in Anspruch nimmt.The advantage of this device is that this baffle is cheap and easy to manufacture and due to its structure in the machine takes up little space.

Anhand eines Ausgestaltungsbeispiels wird die Erfindung nachfolgend näher erläutert:The invention is explained in more detail below using an embodiment example:

Fi g. 1 zeigt die Vorrichtung im Längsschnitt.Fi g. 1 shows the device in longitudinal section.

F i g. 2 zeigt die Vorrichtung in Draufsicht.F i g. 2 shows the device in plan view.

Die Vorrichtung besteht aus einem sich über die Bogenbreite erstreckenden Luftleitblech 1, das parallel zur Bogenebene vor dem Auslegerstapcl angeordnet ist. Das Luftleitblech 1 enthält sich über die Breite erstrekkenden Zungen 2, die aus dem Luftleitblech 1 unter Bildung von Schlitzen 3 herausgebogen sind. Die Zun-The device consists of an air baffle 1 extending over the width of the sheet and parallel to the Arch plane is arranged in front of the Auslegerstapcl. The air baffle 1 contains extending over the width Tongues 2 which are bent out of the air baffle 1 to form slots 3. The first

Patentansprüche:Patent claims: 1. Vorrichtung zum schnellen und kantengenauen Ablegen von Bogen in Druckmaschinen, insbesondere Druckmaschinen mit Tiefstapelauslage, wobei der abzulegende Bogen von einem dem Druckzylinder nachgeschalteten endlos umlaufenden Kettengreifersystem dem Auslegerstapel zugeführt wird, dadurch gekennzeichnet, daß unmittelbar in Bogenlaufrichtung vor dem Auslegerstapel ein sich über die gesamte Bogenbreite erstreckendes Luftleitblech 1 angeordnet ist, welches sich über die Breite erstreckende Zungen 2, die aus dem Luftleitblech 1 unter Bildung von Schlitzen herausgebogen sind, aufweist wobei die Zungen 2 entgegen der Bogenlaufrichtung geneigt sind.1. Device for the fast and precise filing of sheets in printing machines, in particular Printing machines with deep pile delivery, the sheet to be deposited from one of the impression cylinders downstream endless circulating chain gripper system is fed to the delivery stack, characterized in that directly in Sheet travel direction in front of the delivery stack an air baffle extending over the entire sheet width 1 is arranged, which over the width extending tongues 2, which from the air baffle 1 are bent out to form slots, with the tongues 2 against the direction of sheet travel are inclined. 2. Vorrichtung nach Anspruch 1, dadurch gekennzeichnet, daß die Vorrichtung mit einem farbabstoßenden Überzug versehen ist.2. Apparatus according to claim 1, characterized in that the device with an ink-repellent Cover is provided. gen 2 sind so aus dem Luftleitblech 1 herausgebogen, daß diese entgegen der Bogenlaufrichtung geneigt sind. Hierdurch wird ein Abschälen des Luftpolsters unterhalb des Bogens ermöglicht, wodurch der Bogen 4 niedergehalten und gebremst wird.gen 2 are bent out of the air baffle 1 that they are inclined against the direction of sheet travel. This enables the air cushion below the sheet to be peeled off, whereby the sheet 4 is held down and is braked. Hierzu 1 Blatt Zeichnungen1 sheet of drawings
