Vorliegende Erfindung betrifft cine. Einrichtung an Bogcnzuführvorrichtungcn, welche ci> möglicht, diese mit Papier zu beschicken, ohne die Zuführvorrichtung anhalten zu brauchen. Die bisher bekannten Vorrichtungen dieser Art haben den Nachteil, daß hierzu eine großeAVaIze benutzt wird, welche den Papierstapcl auscinanderzieht und umwendet. Diese Anordnung erfordert eine besondere Sorgfalt bei .der Schichtung des Papiers und hat außerdem den Nachteil, daß bei empfindlichen Papieren durch Druck oder Reibung Verletzungen der einzelnen Bogen entstehen können. Im Gegensatz hierzu ermöglicht vorliegende Erfindung das ununterbrechend. Arbeiten unter Verwendung flachlicgcndcr Papierstapcl. ■ · .The present invention relates to cine. Facility to sheet feeder, which allows them to be loaded with paper without need to stop the feeder. The previously known devices of this type have the disadvantage that there is a large avaIze is used, which pulls the paper stack apart and turns it over. This arrangement requires special care when layering of the paper and also has the disadvantage that, in the case of sensitive papers, pressure or friction cause injuries to the individual Arch can arise. In contrast, the present invention enables this uninterruptedly. Working using flat licgcndcr Paper stack ■ ·.

Der Gegenstand der Erfindung ist in beiliegender Zeichnung in mehreren Ausführ rungsformen dargestellt.The object of the invention is shown in the accompanying drawings in several embodiments forms shown.

In Fig. ι ist ti. derjenige Papierstapel, von dem eine Bogenzuführvorrichtung die obersten Bogen entnimmt. .Unter diesem Papierstapcl ist eine Stapelplatte b angeordnet, auf welcher der Drucker einen zweiten Papierstapel c wäh-> rend des Ganges der Maschine' zurechtlegen kann. Ist dies erfolgt und ist der Papierstapel a genügend' weit aufgebraucht worden, so wird die Stapelplatte /;, welche ebenso wie das Tragorgan des Papicrstnpels α in lotrechter Rich-.30 tung verschiebbar ist, von Hand so weit nach oben gedreht, daß die Oberfläche des Stapels c dicht unter dem .Tragorgan des Stapels α zu liegen kommt. Dieses Tragorgan des- Stapels a besteht aus einer dünnen Platte d, welche seitlich beispielsweise · in der Richtung des in _;35 Fig. 2 eingezeichneten Pfeiles verschiebbar isf;' Über dieser Platte liegt ein biegsamer Belag e, beispielsweise ein Leincntucli, welches an einem Ende bei f befestigt ist, so daß es also die Verschiebung der Platte d nicht mitmacht. An seinem anderen Ende ist der Belag c an einer dünnen Walze g befestigt, welche vor der Kante der Platte d drehbar gelagert ist. Dreht man nun die Walze g in der Richtung des eingezeichneten Pfeiles, so schiebt man dadurch, wie Fig. 2 zeigt, die Platte d heraus. Der obere Papierstapel α legt sich dabei auf den Papierstapel c, ohne sich seitlich zu verschieben, da ja der Belag e eine Verschiebung nicht erfährt. Ist die Platte d gänzlich aus dem Papierstapel herausgeschoben worden, so verschiebt man sie nach unten und führt sie, wie Fig. 3 zeigt, durch Schicben in der Richtung des einge- ' zeichneten Pfeiles unter den Papierstapel, der .ebenfalls wieder keine Verschiebung erfährt, da der Belag e nicht verschoben wird. Selbstverständlich muß bei Einleitung des Hineinschiebens der Platte d die Unterkante des Papicrstapels c bei h so weit angehoben werden, daß die Walze g unter dieselbe fassen kann. Wird die Platte d nun vollends hineingeschoben, wie es Fig. 4 zeigt, so kann man die leere Platte b nach unten verschieben, da der Papierstapel c nunmehr von der Platte d getragen wird. Auf diese Weise bildet sich zwischen den Platten b und d ein Zwischenraum, und es ist dem ' Drucker möglich, auf der Platte b erneut einen Papierstapel vorzubereiten, wie es Fig. 1 zeigt.In Fig. Ι is ti. that stack of paper from which a sheet feeder removes the top sheet. .Under this paper stack a stacking plate b is arranged on which the printer can lay out a second stack of paper c while the machine is in motion. Once this has been done and the stack of paper a has been used up sufficiently, the stacking plate /; which, like the support element of the stack of paper α, can be displaced in the vertical direction, is turned upward by hand so far that the surface of the stack c comes to lie just below the .Tragorgan of the stack α. This support member of the stack a consists of a thin plate d, which laterally for example · in the direction of the in _; 35 Fig. 2 drawn arrow is displaceable; ' Over this plate lies a flexible covering e, for example a linen cloth, which is fastened at one end at f , so that it does not take part in the displacement of plate d. At its other end, the covering c is attached to a thin roller g, which is rotatably mounted in front of the edge of the plate d. If one now rotates the roller g in the direction of the arrow drawn, then, as shown in FIG. 2, the plate d is pushed out. The upper stack of paper α lies on top of the stack of paper c without shifting sideways, since the covering e does not experience a shift. When the plate d has been pushed completely out of the stack of paper, it is pushed down and, as shown in FIG. since the lining e is not shifted. Of course, when initiating the pushing in of the plate d, the lower edge of the stack of papers c at h must be raised so far that the roller g can grasp underneath it. If the plate d is now fully pushed in, as shown in FIG. 4, the empty plate b can be pushed down, since the stack of paper c is now carried by the plate d . In this way, a space is formed between plates b and d , and it is possible for the printer to prepare a new stack of paper on plate b , as FIG. 1 shows.

Claims

It is therefore not necessary to shut down the machine in order to load the device with new paper. Since in many cases the space required to push the plate d out to the side (Figs. 2 and 3) is missing, the upper stacking plate d can be removed be made of flexible material, as Fig. 5 shows. Such a flexible material is, for example, corrugated iron; individual rods can also be linked together in an articulated manner, in the manner of a blind. Because the stacking plate, which of course has to be guided laterally in suitable rails, is flexible · '.' it can be wound up at k or otherwise accommodated in a form that takes up little space. Furthermore, appropriately thin watch spring steel strips are used as the covering, which are arranged in a corresponding number next to one another and do not show any wear. 6 shows an embodiment in which the covering e is not wound up on the roller g, but runs around it and is guided along the stacking plate so that it can be wound up outside the paper stack c at m. This arrangement has a merit that the roller g and the stacking plate d can be kept thin. In this arrangement too, thin steel strips are advantageously used as the covering. ■. A further embodiment of the device is shown in FIGS. 7, 8 and 9. In this arrangement, the support member itself is so flexible; that it has the same effect as the covering shown in FIG. 6 in that it folds down and can be brought in or out by pushing or pulling at the folded end. For this purpose, for example, a type of construction designed in the manner of the known roller blinds is suitable, in which the support element consists of a number of rods M1, n, n, etc. connected to one another in an articulated manner. The support member can be guided in various ways, for example by means of slidable rails which are arranged on both sides and are denoted by fi in FIGS. 8 and 9. These rails have two parallel, superimposed guide grooves q, the partition wall of which is missing at the end which is led away under the stack of paper during the displacement ^, so that the support member guided in the grooves (/ is thereby turned downwards. If the support element is displaced at its free end by pushing or pulling, the lateral guide rails f also shift accordingly Rails p and r in section with the support element omitted. • Patent claims:

For paper stacks certain support 'organ, which can be moved under the stack of paper without moving the same with, characterized in that the support member is composed of the stacking plate (d) and a flexible covering (e) which does not move , but instead winds on that edge of the stacking plate (d) which is guided along under the stack of paper (a) when the stacking plate is pulled out or pushed in.

2. Support member according to claim 1, characterized

'characterized in that the stacking plate (d) ■ ■ consists of flexible material or rigid parts connected in the manner of blinds.

3. Support member according to claim 1 and 2, characterized in that thin steel strips are used as a covering for the stacking plate (d).

4. Support member according to claim 1 to 3, characterized in that the winding of the covering of the stacking plate (d) does not take place at the edge thereof, but outside the paper stack, so that the covering is passed around the inner edge of the stacking plate to the outside.

5. Support member according to claim i, characterized in that the covering is strong enough is designed to be able to carry the stack of paper, so that the stacking plate itself
