Die vorliegende Erfindung betrifft ein Verfahren und eine Vorrichtung zur Ausführung desselben, durch welches zusammenhanglose einzelne Papierblätter oder andere Werkstücke von einem Stapel beständig sich drehenden Walzen einer Maschine ununterbrochen zugeführt werden. Das Verfahren besteht darin, daß die bei jeder Walzenumdrehung vom Stapel einzeln abgesaugten Blätter inThe present invention relates to a method and apparatus for performing it the same, through which disjointed individual sheets of paper or other workpieces continuously fed from a stack of continuously rotating rollers to a machine will. The method consists in that the sheets sucked from the stack individually with each revolution of the roller in
ίο den ihrer Form entsprechend gestalteten Ausschnitt einer Hohlwalze hineingebogen und durch Mitnahme mittels dieses Ausschnittes der Berührungsstelle der beiden beständig sich drehenden Walzen zugebogen, von diesen ergriffen, zwangläufig angespannt und weitergeführt werden, um im Weiterlaufen dann eine beliebige Bearbeitung zu erfahren. Dadurch, daß beim Vorschieben des einen Werkstücks das nachfolgende sich bereits auf dem Wege zu oder schon in dem Ausschnitt der Hohlwalze befindet, wird die ununterbrochene Zuführung gesichert und es werden selbst erhebliche Größenabweichungen der Werkstücke infolge der zwangläufigen Führung ausgeglichen.ίο the cutout designed according to its shape bent into a hollow roller and by being carried along by means of this cutout, the point of contact between the two is resistant bent to rotating rollers, gripped by them, inevitably tense and carried on in order to experience any processing as you continue. Through this, that when one workpiece is advanced, the next one is already on the way to or already in the section of the The uninterrupted feed is ensured and it becomes self Significant size deviations of the workpieces as a result of the compulsory guidance balanced.
Die Zeichnung zeigt schematisch eine Ausführungsform der Vorrichtung zur Ausführung des Verfahrens, und zwar in Fig. 1 im Längsschnitt, in Fig. 2 und 3 in Einzelanordnungen und in Fig. 4 in Draufsicht.The drawing shows schematically an embodiment of the device for execution of the method, namely in Fig. 1 in longitudinal section, in Fig. 2 and 3 in individual arrangements and in Fig. 4 in plan view.
Mittels beliebiger Luftpumpenanordnung wird vom Papierstapel α Blatt für Blatt durch den Sauger b abgesogen und so lange festgehalten, bis die um ihre Welle sich drehenden Arme c es von hinten treffen und den entsprechend riahegelegenen, beständig umlaufenden Einführwalzen d, e zubiegen. Die obere Walze e ist hohl und mit einem Ausschnitt / versehen, durch welchen das derselben zugebogene Blatt in den Hohlraum der Walze e eintritt, so daß es beim Weiterlauf en der Walze von der Kante des Ausschnittes vollends herabgebogen, der Berührungsstelle der Walzen d, e zugebogen, von diesen ergriffen , zwangläufig angespannt und den Arbeitswalzen g, h zugeführt wird.Using any air pump arrangement, the paper stack α is sucked off sheet by sheet by the suction device b and held there until the arms c rotating around their shaft hit it from behind and bend the continuously rotating infeed rollers d, e . The upper roller e is hollow and provided with a cutout / through which the sheet bent towards the same enters the cavity of the roller e , so that when the roller continues it is bent down completely from the edge of the cutout, the contact point of the rollers d, e bent closed, gripped by these, inevitably tensioned and fed to the work rolls g, h.
Der Stapel α kann bei entsprechend geänderter Lage der Ansaugungs- und Führungsvorrichtungen auch in wagerechter Lage angeordnet werden.The stack α can also be arranged in a horizontal position with a correspondingly changed position of the suction and guide devices.
