Description

Vorrichtung zum Zerreißen von Papier Die Erfindung betrifft eine Vorrichtung zum Zerreißen von Papier; insbesondere soll der Gegenstand der Erfindung zum Vernichten von Akten dienen.Apparatus for tearing paper The invention relates to an apparatus for tearing paper; In particular, the object of the invention is intended to destroy of files serve.

Es sind Vorrichtungen zum Zerkleinern von papierartigem Gut bekannt, bei denen ein nach Art eines Fräsers 'arbeitendes Werkzeug in einem Gehäuse oberhalb eines Rostes umläuft und eine Saugleitung zum Abführen des in Papierstoff übergeführten Gutes an das Gehäuse unterhalb des Rostes angeschlossen ist. Erfindungsgemäß soll die Zerreißwirkung dieser bekannten Vorrichtung verbessert werden, und zwar dadurch, daß in der dem Papiereinwurf gegenüberliegenden Stirnwand des Gehäuses radial zur Achse des Werkzeuges Leisten von dreieckigem Querschnitt angeordnet sind.There are devices for comminuting paper-like material known, in which a tool working in the manner of a milling cutter is located in a housing above of a grate and a suction line for discharging the material that has been converted into paper stock Good is connected to the housing below the grate. According to the invention the tearing effect of this known device can be improved, namely by that in the end wall of the housing opposite the paper slot radially to Axis of the tool bars of triangular cross-section are arranged.

Bei Betrieb der Vorrichtung wird das von dem fräserartigen @Verkzeug erfaßte Papier quer über diese Leisten hinweggeschleudert, wobei letztere dem Papier eine erhöhte Reibungsfläche darbieten und infolgedessen die Zerreißwirkung des fräserartigen Werkzeuges wesentlich unterstützen.When the device is in operation, this is done by the milling tool seized paper thrown across these bars, the latter being the paper present an increased friction surface and consequently the tearing effect of the cutter-like Support the tool significantly.

Auf der Zeichnung ist der Gegenstand der Erfindung beispielsweise dargestellt; es zeigen Abb. i einen senk-rechten Schnitt durch das Gehäuse in der Längsrichtung der Werkzeugachse, Abb.2 einen senkrechten Schnitt durch das Gehäuse quer zur Werkzeugachse, Abb.3 in Ansicht die Gesamtanordnung der Vorrichtung in kleinerem Maßstabe.In the drawing, the subject of the invention is for example shown; Fig. i shows a vertical-right section through the housing in the Longitudinal direction of the tool axis, Fig. 2 a vertical section through the housing at right angles to the tool axis, Fig. 3 shows the overall arrangement of the device in smaller scale.

In einem Gehäuse i, das in seinem oberen Teil halbzylindrisch ist, ist ein fräserartiges umlaufendes Werkzeug 2 angeordnet, dessen äußere Kanten einen wesentlichen Abstand von der Innenwand des Gehäuses haben. Die Welle des Werkzeuges ist mit 3 bezeichnet. Die Fortsetzung des halbzylindrischen Teiles des Gehäuses i wird durch einen Rost 4 gebildet, dessen Roststäbe einen dreieckigen Querschnitt haben und in einem Halbkreis angeordnet sind. In das Gehäuse mündet ein Rohr 5, das als Papiereinwurf dient. Auf der dem Papiereinwurf gegenüberliegenden Stirnwand des Gehäuses i sind erfindungsgemäß radial zur Achse des fräserartigen Werkzeuges Leisten 6 von dreieckigem Querschnitt angeordnet.In a housing i, which is semi-cylindrical in its upper part, a milling cutter-like rotating tool 2 is arranged, the outer edges of which a have a substantial distance from the inner wall of the housing. The shaft of the tool is denoted by 3. The continuation of the semi-cylindrical part of the case i is formed by a grate 4, the grate bars of which have a triangular cross-section and are arranged in a semicircle. A pipe 5 opens into the housing, that serves as a paper slot. On the front wall opposite the paper slot of the housing i are, according to the invention, radial to the axis of the cutter-like tool Bars 6 arranged by a triangular cross-section.

Wie in Abb. 3 durch einen Pfeil angedeutet, wird das Papier in das Rohr 5 eingeworfen und durch das umlaufende, von einem Motor 7 angetriebene fräserartige Werkzeug 2 zerkleinert, indem es gegen den Rost 4. und die im Querschnitt dreieckigen Leisten 6 geschleudert wird. Der Abstand der Roststäbe bestimmt die Größe der Papierteilchen. Die durch den Rost hindurchfallenden Papierteilchen fallen in der Richtung des punktiert gezeichneten Pfeiles und werden durch einen Ventilator 8 über ein Rohr 9 nach einem nicht dargestellten Sammler gefördert, wie es durch die Pfeile angedeutet ist.As indicated by an arrow in Fig. 3, the paper is inserted into the Tube 5 thrown in and through the rotating, driven by a motor 7 cutter-like Tool 2 crushed by placing it against the grate 4. and the triangular in cross-section Last 6 is thrown. The distance between the grate bars determines the size of the paper particles. The paper particles falling through the grate fall in the direction of the dotted drawn arrow and are by a fan 8 via a pipe 9 after a not shown collector promoted, as indicated by the arrows.
