Description

Bogenzuführungsvorrichtung mit Bogentrennung durch Blasluft Bei denjenigen Bogenzuführungsvorrichtungen, bei denen die Trennung des obersten Bogens eines Stapels unter Zuhilfenahme von Blasluft erfolgt, wird je nach Papiersorte und Gewicht mehr oder weniger Luft zwischen die Bogen geleitet. Diese Blasluft besorgt gleichzeitig ein Entstauben der Bogen, das bekanntlich ein Vorteil dieses Verfahrens ist. 1 acliteilig ist dieses Entstauben insofern, als der Papierstaub willkürlich in den Maschinenraum geblasen und dadurch ein Verschmutzen der Maschine bewirkt wird. Besonders ins Gewicht fällt' diese Erscheinung an Bogenzuführungsvorrichtungen, bei denen die Trennung der Bogen mittels Blasluft an dem der Förderrichtung entgegengesetzten Ende des Stapels geschieht, weil der staubhaltige Luftstrom hierbei unmittelbar in die bogen=erarbeitende Maschine geführt wird. so daß besonders bei starkstäubenden Papieren Störungen sowohl in der Bogenzuführungsvorrichtung als auch in der ihr angeschlossenen Maschine hervorgerufenwerden können.Sheet feeding device with sheet separation by blown air For those Sheet feeders that allow the separation of the top sheet of a stack takes place with the help of blown air, depending on the type of paper and weight, more is or less air is passed between the sheets. This blown air worries at the same time dedusting of the sheets, which is known to be an advantage of this method. 1 acli part This dedusting is insofar as the paper dust enters the engine room arbitrarily blown and this causes soiling of the machine. Especially important This phenomenon occurs on sheet feeders in which the separation the sheet by means of blown air at the end of the opposite to the conveying direction Stacking happens because the dusty air flow here directly in the arch = working Machine is guided. so that especially with very dusty papers disturbances both in the sheet feeding device as well as in the machine connected to it can.

Dieser Übelstand wird nach der Erfindung durch Anordnung einer Staubsaugevorrichtungbeseitig t. Die Erfindung ist in beiliegender Zeichnung in Abb. z im Aufriß dargestellt, während in Abb. 2 eine beispielsweise Ausführung der Saugvorrichtung gezeigt wird. Es bezeichnet a den Papierstapel, der auf einem Tisch b ruht, c ist die vordere Anschlagleiste, cd eine Förderrolle, die den jeweils obersten Bogen e vom Sauger g übernimmt und dem Tisch f übergibt, la bezeichnet einen Sauger, der den obersten Bogen ankippt und trennt, i einen Bläser, der die Trennung der Bogen unterstützt und entstaubt, h einen kastenförmigen Hohlkörper zwischen Stapel a und Förderrolle d. Dieser Hohlkörper ist in vorliegendem Ausführungsbeispiel mit üftnungen l versehen, durch die der Staub eingesaugt «-erden kann. Die weitere Entfernung des Staubes geschieht durch Anschlußr ohrstücke m. Der Bläser i drückt einen Luftstrom unter den obersten Bogen c. Der aufwirbelnde Staub wird dabei in Richtung auf die Förderrolle hingeblasen und von dem an eine Saugpumpe angeschlossenen Hohlkörper k abgesaugt und mittels eines Filters unschädlich gemacht.This drawback is eliminated according to the invention by the arrangement of a vacuum cleaner. The invention is shown in elevation in the accompanying drawing in Fig. Z, while in Fig. 2 an example embodiment of the suction device is shown. A denotes the stack of paper that rests on a table b, c is the front stop bar, cd a conveyor roller that takes the top sheet e from the suction device g and transfers it to the table f, la denotes a suction device that tilts the top sheet and separates, i a blower that supports the separation of the sheets and removes dust, h a box-shaped hollow body between the stack a and the conveyor roller d. In the present exemplary embodiment, this hollow body is provided with openings 1 through which the dust can be sucked in. The further removal of the dust is done by connecting pipe pieces m. The blower i pushes a stream of air under the top sheet c. The swirling dust is blown in the direction of the conveyor roller and sucked off by the hollow body k connected to a suction pump and rendered harmless by means of a filter.
