Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Den Erfmdungsgegenstand bildet eine Vorrichtung zur Entnahme eines Blattes von einem Blätterstapel von unten her unter Verwendung biegsamer Bänder. Neu ist die An-5 Ordnung eines hin und her bewegbar gelagerten Schlittens, welcher eine Saugwalze mit von dieser nach einem feststehenden Anschlag führendem biegsamen Band und ein endloses, über Rollen laufendes biegsames Band trägt.The subject matter of the invention forms a device for removing a sheet of a stack of sheets from below using flexible straps. The An-5 is new Order of a slide mounted so that it can move back and forth, which has a suction roll with from this flexible band leading to a fixed stop and an endless, bears flexible tape running over rollers.

ίο Durch diese Anordnung wird erreicht, daß der Papierstapel beim Abnehmen des untersten Blattes auf freiliegenden Bändern ruht, welche sich an den Papierblättern abwälzen und so Gewähr leisten, daß sich der Papierstapel in keiner Weise verschieben kann.ίο This arrangement ensures that the stack of paper rests on exposed bands when removing the bottom sheet, which roll on the sheets of paper and thus ensure that the stack of paper is in no way can move.

Eine Ausführungsform der Vorrichtung ist auf der Zeichnung schematisch in drei Arbeitsstellungen in Seitenansicht dargestellt. Der Blätterstapel 1 liegt lose auf der aus den Bändern 5 gebildeten Tragfläche. Lediglich zum Zwecke, einen Anschlag für den Stapel zu besitzen, sind Wandungen 2 vorgesehen, zwischen denen der Stapel mühelos in die richtige Lage gebracht werden ■ kann.An embodiment of the device is shown schematically in the drawing in three working positions in a side view. Of the The stack of sheets 1 lies loosely on the support surface formed from the bands 5. Only for the purpose of having a stop for the stack, walls 2 are provided, between which the stack can be easily brought into the correct position.

Bemerkt sei ausdrücklich, daß diese Wandungen nicht unbedingt erforderlich sind, sondern daß der Stapel vollständig frei auf seiner Bandtragfläche ruhen kann.It should be expressly noted that these walls are not absolutely necessary, but that the stack can rest completely freely on its belt support surface.

Die Wirkungsweise der dargestellten Vorrichtung ist folgende:The mode of operation of the device shown is as follows:

Befindet sich die Vorrichtung in der aus Fig. ι ersichtlichen Stellung, so ist das Band 5 vom Umfang der Walze 3 abgewickelt, und auf ihm ruht der Stapel 1, Nunmehr wird das untere Blatt des Stapels durch Saugdüsen 4 angesaugt; hierauf wird der Schlitten 6 in Pfeilrichtung bewegt. Bei dieser Bewegung wird gleichzeitig die Walze 3 in Pfeilrichtung gedreht, desgleichen die beiden Walzen 7 und 8. Das Band 5 wickelt sich nun über die Walze 3, und das Band 9 wiederum wälzt sich am nächsten Blatt des Stapels ab (s. Fig. 2 und 3).If the device is in the position shown in FIG unwound from the circumference of the roller 3, and on it rests the stack 1, Now is the lower sheet of the stack sucked by suction nozzles 4; then the slide 6 moved in the direction of the arrow. During this movement, the roller 3 is simultaneously moved in the direction of the arrow rotated, likewise the two rollers 7 and 8. The tape 5 now winds over the roller 3, and the tape 9 again rolls off the next sheet of the stack (see Figs. 2 and 3).

Irgendwelche Bewegung wird auf den Stapelrest nicht übertragen, da sich die Bandtragflächen am Stapel abwälzen. Ist auf diese Weise das untere Blatt abgehoben und von den Saugdüsen 4 freigegeben, so kann sich nach Rückgang der Vorrichtung in die Anfangsstellung nach Fig. 1 das Spiel von neuem wiederholen.Any movement is not transferred to the rest of the stack, since the belt support surfaces roll on the stack. If the lower sheet is lifted off in this way and released by the suction nozzles 4, so can after the device has returned to its initial position according to FIG. 1, the game starts again repeat.
