Description

Vorrichtung zum Vorlockem und Trennen der Kanten der obersten Bogen eines Stapels Bei Vorrichtungen zum Trennen einzelner Bogen von einem Bogenstapel ist es bereits bekannt, in Verbindung mit den Trennsaug-Lrn Druckelemente zu benutzen, welche ,entweder gemeinsam mit den Trennsaugern oder früher als diese ,auf den obersten Stapelbogen auftreffen und einen entsprechenden Druck auf die Stapeloberfläche ausüben, dzr ein geringes Aufblättern der Bogenkantent"eile unter d.cm Trennsauger zur Folge hat, so daß dieser Teil des obersten Stapelbogens sicher allein vom Trennsauger angesaugt wird.Device for pre-locking and separating the edges of the top sheet of a stack In devices for separating individual sheets from a stack of sheets it is already known to use pressure elements in connection with the separating suction tubes, which, either together with the suction cups or earlier than these, on the top one Hit the stack sheet and exert a corresponding pressure on the stack surface, This results in a slight peeling of the arched edge parts under the cm separating sucker has, so that this part of the uppermost stack sheet is safe from the separating sucker is sucked in.

Die Erfindung besteht darin, daß das Druckelement zugleich mit dem Druck auf die Stapeloberfläche eine vom aufzublätternden Kantenteil weggerichtete streichend,. Bewegung ausführt und zweckmäßig durch einen an dem Saugerträger aasgelenkten, mit einer Druckrolle versehenen Winkelarm gebildet ist, der unter dem Gegendruck des Stapels gegen den Druck einer Feder sich von dem aufzublätternden Kantenteil wegbewegt.The invention consists in that the pressure element at the same time with the Pressure on the stack surface directed away from the edge part to be opened painting ,. Executes movement and expediently by a provided with a pressure roller angle arm is formed under the counter pressure of the stack against the pressure of a spring from the edge part to be opened moved away.

Auf der Zeichnung ist ein Ausführungsbeispiel einer Vorrichtung zum Vorlockern und Trennen der Stapelbogen g,-mäß der Erfindung im Aufriß dargestellt.In the drawing is an embodiment of a device for Loosening and separating the stacked sheet g -shown in elevation according to the invention.

Über den obersten Stapelbogen S eines Bogenstapels St sind vertikal auf und nieder gehende und in einem bestimmten Winkel schwenkbare Trennsauger T angeordnet. An einer Seitenfläche der Trennsaugerführung C'r ist eine ' unter Federdruck stehende Druckrolle ,R gebildet, die beim Auftreffen auf den obersten Stapelbogen einen dem Druck der Feder H entsprechenden Gegendruck auf die Stapeloberfläche ausübt. Hierbei bewvegt sich der Rollenhebel P in einer kleinen Schwingbewegung rum den Zapfen Z. Entsprechend bewegt sich die Rolle R entgegengesetzt zum aufzublätternden Kantenabschnitt der Bogen. Durch den dabei :entstehenden rollenden Reibungsdruck wird eine Vorlockerungder Bogenkanten und die Beseitigung der zwischen den Bogenflächen vorhandenen Adhäsion herb:igeführt. .Above the top stack sheet S of a sheet stack St are vertical separating suction cups T that go up and down and pivot at a certain angle arranged. On a side surface of the separating suction cup guide C'r is a 'under spring pressure standing pressure roller, R formed when it hits the top stack sheet exerts a counter pressure corresponding to the pressure of the spring H on the stack surface. Here, the roller lever P moves around in a small swinging motion Pin Z. Correspondingly, the roller R moves in the opposite direction to the one to be opened Edge portion of the arch. Due to the resulting rolling friction pressure is a loosening of the sheet edges and the elimination of those between the sheet surfaces existing adhesion bitter: iguided. .
