Description

Selbsttätige Bogenzuführvorrichtung für Druckmaschinen, Falzmaschinen .u. dgl. Gegenstand des Hauptpatents ist eine Bogenzuführvorrichtung, bei der durch ein sich drehendes System von Saugern ein rascheres Abheben der Bogen vom Stapel erfolgt als bisher. Vorliegende Erfindung hat -den Zweck, diese Bogenzuführvorrichtung dahin zu vervollkommnen, daß sie die Bogen unmittelbar unter Vermeidung jeglichen . Bandes oder von Förderrollen o. dgl. dem Druckzylinder zuführt. Hierzu ist es notwendig, daß die Bogen aus dem Ruhezustand auf dem Stapel etwas verschoben, d. h. so gestellt werden, daß sie unmittelbar vom Stapel in die richtigeRegisterstellung kommen und aus dieser -aus dem Zustand der Ruhe unmittelbar abgenommen und unmittelbar dem Druckzylinder zugeführt werden können. Diese Verschiebung erfolgt in der Weise, daß die Bögen um ein bestimmtes .Stück seitwärts und nach vorn bewegt werden und dann Registerstellung erhalten. Die Erfindung ist auf der Zeichnung in einem Ausführungsbeispiel schematisch. dargestellt.Automatic sheet feeding device for printing machines, folding machines, etc. Like. The subject of the main patent is a sheet feeder in which a rotating system of suction cups is a faster lifting of the sheets from the stack than before. The present invention has the purpose of perfecting this sheet feeding device in such a way that the sheets can be delivered directly while avoiding any. Tape or from conveyor rollers or the like. Feeds the printing cylinder. For this it is necessary that the sheets are shifted somewhat from the resting state on the stack, that is to say placed in such a way that they come directly from the stack into the correct register position and from this - from the resting state they can be immediately removed and fed directly to the impression cylinder. This shift takes place in such a way that the sheets are moved sideways and forwards by a certain .Piece and then obtained register position. The invention is shown schematically in an exemplary embodiment in the drawing. shown.

Man erkennt aus den Abb. z und wieder das sich drehende Saugersystema,d,aa, welches mittels der Anne d auf der Welle e gelagert ist, und welches sich in der Richtung der eingezeichneten Pfeile dreht. Damit nun die Sauger die Bogen gleich richtig erfassen, werden diese vom Stapel b in der eingangs erwähnten Weise verschoben. Hierzu dient ein Hebelsystem h, welches einerseits auf einer Welle i. schwenkbar gelagert ist, anderseits auf seinem freien Ende in einer Gabel o. dgl. eine Saugerstange k trägt. Außerdem sitzt auf der Welle i roch ein Hebel 1, der mit seinem oberen Ende an einer Kurvenscheibe m anliegt, die auf der Welle e läuft und durch die Zahngetriebe n und o die dreifache Umlaufzahl des Saugersystems erhält.You can see from Fig. Z and again the rotating suction cup systema, d, aa, which is mounted by means of the Anne d on the shaft e, and which is in the Rotates in the direction of the arrows. So now the suckers grasp the sheet immediately correctly, these are from the stack b in the aforementioned Way moved. A lever system h, which is on the one hand on a shaft, is used for this purpose i. is pivotably mounted, on the other hand on its free end in a fork o. Like. A suction rod k carries. Also sitting on the shaft i smelled a lever 1, which rests with its upper end on a cam disk m, which is on the shaft e runs and through the toothed gears n and o three times the number of revolutions of the suction system receives.

Durch die angegebenen Mittel wird die Saugerstange k über den Rand des Bogenstapels b geführt und hier etwas gesenkt. Darauf ergreift sie den obersten Bogen und zieht ihn in der obenerwähnten Weise, und zwar wie dies Abb. 3 und 4 zeigen, ein bestimmtes :Stück seitwärts und nach vorn. Sodann läßt sie ihn los und schwenkt aus dem Wege. Der Bogen kommt in seiner neuen Stellung sofort zur Ruhe und erhält in dieser Stellung genaues Register durch irgendeine beliebige Schieb- oder Ziehvorrichtung. Inzwischen ist der Saugera des Saugersystems herangekommen und erfaßt den genau eingestellten Bogen, um ihn mitzunehmen und unmittelbar dem Druckzylinder zuzuführen.By the means indicated, the sucker rod k is over the edge out of the sheet stack b and lowered a little here. Then she takes the top one Bow and draw it in the above-mentioned manner, as shown in Figs. 3 and 4, a certain: piece sideways and forward. Then she lets go of him and waves out of the way. The bow immediately comes to rest in its new position and is maintained in this position exact register by any pushing or pulling device. In the meantime, the suction device of the suction system has come up and grasps it precisely set sheet to take it with you and feed it directly to the impression cylinder.
