Description

Pneumatischer Bogenanleger. Bekannte Systeme selbsttätiger Bogenanleger mit ständig nach einer Richtung sich drehender Saugtrommel weisen den Übelstand auf, daB nach erfolgtem Bogenansaugen die darunterliegenden, nicht mitangehobenen Bogen beim Zurückgehen der Saugtrommel durch die drehende Bewegung der letzteren vom Papierstapel geschleift werden. Diesem übelstand abzuhelfen, ist der Zweck der vorliegenden Erfindung; er soll durch die Anordnung einer mittels Ketten sich drehenden, an einem Ende drehbarer Schienen zum Zweck des Bogenansaugens hin und her laufenden Saugtrommel dadurch erreicht werden, daB nach erfolgtem Bogenansaugen und während der Rückwärtsbewegung der Saugtrommel auf den Schienen diese an dem die Saugtrommel tragenden Ende angehoben werden.Pneumatic sheet feeder. Known systems of automatic sheet feeders with the suction drum constantly rotating in one direction show the disadvantage that after the bow suction has taken place, the ones underneath that are not lifted Arch when the suction drum goes back due to the rotating movement of the latter be dragged from the stack of paper. To remedy this evil is the purpose of present invention; it is supposed to be through the arrangement of a chain rotating, rotatable rails running back and forth at one end for the purpose of sheet suction Suction drum can be achieved by the fact that after the sheet has been sucked in and during the backward movement of the suction drum on the rails this on which the suction drum load-bearing end can be raised.

Die Zeichnung stellt einen Schnitt durch die Mitte dar. Auf dem Seitenteil f der Druckmaschine ist der Lagerbock a festgeschraubt. An diesem befindet sich der Zapfen b, an dem die Schiene c drehbar angeordnet ist. Die durch Antriebsrad y mittels Kettenübertragung ständig nach einer Richtung sich drehende Saugtrommel t wird mittels der Laufkatze k auf der Schiene c in der Weise gegen und über den Stapel hin bewegt, daB ein Abrollen der Saugtrommel über dem Papierstapelende zum Zweck des Bogenansaugens stattfindet (Fig. i bis 3). Nach erfolgtem Bogenansaugen wird die Schiene c durch den Hebel ds gehoben, so daB während der Rückwärtsbewegung der Saugtrommel (Fig. 4) in die Stellung von Fig. i ein Fortschleifen nicht mitangehobener Bogen vom Papierstapel durch die drehende Bewegung der Saugtrommel vermieden wird.The drawing shows a section through the middle. On the side part f the printing machine, the bearing block a is screwed tight. This is located the pin b on which the rail c is rotatably arranged. The through drive wheel y suction drum constantly rotating in one direction by means of chain transmission t is by means of the trolley k on the rail c in the way opposite and over the Stack moves towards the fact that the suction drum rolls over the end of the paper stack Purpose of the bow suction takes place (Fig. I to 3). After the bow suction has taken place the rail c is lifted by the lever ds, so that during the backward movement the suction drum (FIG. 4) in the position of FIG Sheet from the stack of paper is avoided by the rotating movement of the suction drum.
