Description

Vorrichtung zum Erfassen, Einziehen und Falzen des der Entnahme-. und Falzwalze zunächst liegenden Blattes eines Blätterstapels Die Erfindung bezieht sich auf eine Vorrichtung zum Fassen, Einziehen und Falzen des der Entnahme- und Falzwalze zunächst liegenden Blattes eines Blätterstapels, bei welcher die eine Hälfte des zu falzenden Blattes vor dem Falzen zwischen der Entnahme-und einer vom Stapelentfernt liegenden Falzwalze durch ein zusätzliches Hilfsglied gegen die Entnahmewalze bewegt und hierbei vom Stapel getrennt wird.Device for capturing, drawing in and folding of the removal. and folding roller lying next to a sheet of a stack of sheets The invention relates on a device for gripping, pulling in and folding of the removal and Folding roller initially lying sheet of a stack of sheets, in which the one Half of the sheet to be folded before folding between the removal and one of the Far away from the stack by means of an additional auxiliary link against the removal roller moved and thereby separated from the stack.

Die Erfindung besteht darin, daß das zusätzliche Hilfsglied als umlaufende Trennwalze geringen Durchmessers ausgebildet ist, welche die freie Hälfte des jeweils einzuziehenden und zu, falzenden Blattes mittels Saugzuges vom restlichen Stapel trennt -und der Entnahme- und Falzwalze zubiegt.The invention consists in that the additional auxiliary member as a circumferential Separating roller of small diameter is formed, which is the free half of each sheet to be drawn in and folded from the rest of the stack by means of suction separates and bends the removal and folding roller.

Hierdurch soll die gleichzeitige Entnahme mehrerer Blätter vom Stapel bei Falzeinzügen unmöglich gemacht werden.This is intended to enable multiple sheets to be removed from the stack at the same time can be made impossible in the case of fold feeds.

Bisher wurden zu diesem Zwecke Vorrichtungen mit ruhenden oder periodisch arbeitenden Reibungswalzen verwandt, die aber ein wahlloses Einlaufen mehrerer Blätter in die Bearbeitungsmaschine nicht verhindern.So far, devices with dormant or periodic were for this purpose working friction rollers, but with an indiscriminate feeding in of several sheets do not prevent it from entering the processing machine.

Andere Vorrichtungen blasen auf die verschiedenste Weise Druckluft in den Blätterstapel, um die gleichzeitige Entnahme mehrerer Blätter zu vermeiden. Doch auch die Verwendung von Druckluft gewährleistet nicht die Entnahme eines einzelnen Blattes, es sei denn, daß die Druckluft schon derart stark ist, daß die Blätter untereinander vollkommen getrennt gehalten werden. Hierbei tritt dann der Fehler in Erscheinung, daß durch die Druckluft die Blätter sich verschieben und die Entnahme ungenau wird.Other devices blow compressed air in a variety of ways into the stack of sheets to avoid removing several sheets at the same time. However, even the use of compressed air does not guarantee that an individual will be removed Leaf, unless the compressed air is so strong that the leaves are kept completely separate from each other. Then the error occurs in appearance that the leaves are displaced by the compressed air and the removal becomes imprecise.

Durch vorliegende Erfindung werden diese Übelstände vollkommen beseitigt, und es wird die genaue Entnahme eines einzelnen Formblattes gewährleistet. Die mit dem Blattstapel dauernd in Berührung liegende Trennwalze nach der Erfindung hat die Aufgabe, das jeweils zu entnehmende Formblatt vor der endgültigen Abnahme vom Blätterstapel von den darüberliegenden Blättern zu trennen und vom Stapel abzubiegen, -und zwar an der Stelle, an der das Formblatt von dem @eigentlichen Entnahmemittel @erfaßt wird, um vom Stapel abgezogen zu werden.The present invention completely eliminates these inconveniences, and the exact removal of a single form is guaranteed. With has the sheet stack permanently in contact separating roller according to the invention the task of completing the respective form before the final acceptance of To separate the stack of sheets from the sheets above and to bend them from the stack, - namely at the point where the form from the actual extraction device @ is detected to be peeled off the stack.

Diese Trennwalze wird in einem geringen Durchmesser gehalten und arbeitet im Takt der Entnahmewalze. Der Angriff der Trennwalze erfolgt bereits dann, wenn das Formblatt von der Entnahmewalze noch nicht @erfaßt ist, also von der Trennwalze erst auf die Entnahmewalze gebracht wird. Die Entnahmewalze erfaßt das Formblatt erst an der Stelle, an der das Blatt schon vom Stapel getrennt ist, so daß die Entnahme eines einzelnen Blattes immer gewährleistet ist.This separation roller is kept in a small diameter and works in time with the take-off roller. The separation roller is already attacked when the form is not yet @ captured by the removal roller, i.e. by the separating roller is first brought onto the removal roller. The take-off roller grips the form only at the point at which the sheet is already separated from the stack, so that the removal of a single sheet is always guaranteed.

Bei dem geringen Durchmesser der Trennwalze ist es erforderlich, diese an der Saugstelle mit einer Abflachung zu versehen, da hierdurch eine entschieden bessere Angriffsmöglichkeit gegenüber dem Papierblatte gegeben ist.Given the small diameter of the separating roller, it is necessary to use it to be provided with a flattening at the suction point, there through this given a decidedly better possibility of attack compared to the paper sheet is.

In der Zeichnung ist :eine Vorrichtung nach der Erfindung beispielsweise dargestellt.In the drawing: a device according to the invention, for example shown.

Die Abb.I zeigt einen Falzeinzug in Aei=-tenansicht.The Fig.I shows a fold feed in Aei = -ten view.

Der Blätterstapel i ruht auf den Stapelplatten z und wird von Stapelhaltern 3 getragen. Unterhalb der Stapelplatten 2 befinden sich die Trennwalze q., welche mit Sauglöchern 5 und der Abflachung i i versehen ist, sowie die Entnahmewalze 6 und Falzwalze 8, von denen die Walze 6 mit Sauglöchern 7 ausgestattet ist.The stack of sheets i rests on the stacking plates z and is held by stack holders 3 worn. Below the stacking plates 2 are the separation roller q. Which is provided with suction holes 5 and the flattening i i, as well as the removal roller 6 and folding roller 8, of which roller 6 is provided with suction holes 7.

Der Arbeitsvorgang vollzieht sich folgendermaßen Das jeweilige Formblatt des Blätterstapels i wird von der Trennwalze q. vermittels der Sauglöcher 5 erfaßt, von den darüberliegenden Blättern getrennt und vom Stapel i abgebogen, wobei das Blatt in die gestrichelte Lage io gebracht wird, so daß dieser Teil des Blattes auf die Entnahmewalze 6, welche ebenfalls mit Sauglöchern 7 versehen ist, zu liegen kommt. lIierauf wird das Blatt von den Sauglöchern 7 der Walze 6 an den vom Stapel getrennten Teil io @erfaßt und unter Bildung einer Falte durch die Walzen 6 und 8 vom Stapel abgezogen. wThe work process is carried out as follows: The respective form of the stack of sheets i is moved by the separating roller q. detected by means of the suction holes 5, separated from the overlying sheets and bent from the stack i, whereby the Sheet is brought into the dashed position io, so that this part of the sheet on the removal roller 6, which is also provided with suction holes 7, to lie comes. Then the sheet is transferred from the suction holes 7 of the roller 6 to the stack separate part io @ detected and forming a fold by the rollers 6 and 8 withdrawn from the stack. w
