Description

Vorrichtung zur Entnahme einzelner Bogen von einem Bogenstapel mittels Saug-und Druckluft. Bei Vorrichtungen zur Entnahme einzelner Bogen von einem Bogenstapel mittels Saug-und Druckluft kommt es vor, daß der von den Saugern angehobene Bogen auch den zweitobersten Bogen mit sich zieht. Um das Zurückfallen dieses zweiten Bogens zu erleichtern, werden gemäß der Erfindung die Blasdüsen zwischen den beiden Endstellungen, in denen in bekannter Weise die oberen Bogen des Stapels zuerst gelockert und dann der oberste Bogen vom Stapel abgetrennt wird, in einer Zwischenstellung eine kurze Zeit lang angehalten, in der durch Blasen auf die .Kaifite des obersten Bogens eine Trennung zwischen diesem und dem etwa mitgerissenen zweitobersten Bogen bewirkt wird.Device for removing individual sheets from a stack of sheets by means of Suction and compressed air. For devices for removing individual sheets from a stack of sheets by means of suction and compressed air it happens that the sheet lifted by the suction cups also pulls the second arch from the top with it. About the falling back of this second one To facilitate the arc, according to the invention, the blow nozzles between the two End positions in which the upper sheets of the stack are first loosened in a known manner and then the top sheet is separated from the stack, in an intermediate position stopped for a short time, during which by blowing on the .Kaifite of the top one Arches a separation between this and the second uppermost arch which has been carried along is effected.

Die Abb. i bis 3 der Zeichnung zeigen die drei Stellungen der Sauger und Blasdüsen. In der Stellung gemäß Abb. i sind die Blasdüsen a noch, nach. unten gerichtet; die Lockerung der oberen Bögen des Stapels b hat durch die Plggluft uAt@er Mitwirkung des Leitbleches c stattgefunden, Und der- angehobene oberste Bogen ist von den Sagern d erfaßt worden. Während sich nun die Sauger d in die Stellung nach Abb. 2 kippen, dreht sich das Blasrohr so weit, bis die Düsen a etwa die Kantenhöhe des obersten Bogens erhalten. Durch das jetzt beginnende sanfte Blasen wird veranlaßt, daß der etwa an dem obersten Bogen haftende zweite Bogen vom ersten wieder abfällt. Nach kurzer Ruhepause steigen die Sauger in die Stellung nach Abb. 3 ; in der gleichen Zeit drehen sich die Düsen a in eine Stellung, in welcher die ausströmende Luft gegen die Unterfläche des obersten Bogens bläst und diesen dadurch vom Stapel gänzlich trennt.Figs. I to 3 of the drawing show the three positions of the suction cups and air nozzles. In the position shown in Fig. I are the Air nozzles a still, after. directed downwards; the loosening of the upper arches of the stack b has through the Plggluft uAt @ he participation of the guide plate c took place, and the raised topmost arch has been grasped by the sayers d. While the sucker d tilt into the position according to Fig. 2, the blowpipe rotates until the nozzles a get about the edge height of the top sheet. Through the gentle that is now beginning Blowing is caused to remove the second sheet approximately adhering to the top sheet falls away from the first. After a short rest, the suction cups rise to the position according to Fig. 3; at the same time the nozzles a rotate into a position in which blows the outflowing air against the lower surface of the top sheet and thereby completely separating it from the stack.
