Description
Papierschneidevorrichtung mit in einem Schneidschlitz einer Führung an. einer Schneidkante hin und her bewegtem Kreismesser Bekannt sind Vorrichtungen zum Schneiden von Papier, bei denen ein Kreismesser verwendet wird, das beim Schneiden von Hand oder durch zusätzlichen Federdruck gegen die Schneidkante gedrückt wird, um einen scharfen Schnitt zu erzeugen. Der mechanische Antrieb dieser bekannten Vorrichtungen kann nur von oberhalb der Papierauflage aus erfolgen, wodurch die freie Benutzung der Tischfläche behindert ist.Paper cutting device with a guide in a cutting slot at. Circular knife moving back and forth with a cutting edge. Devices are known for cutting paper using a circular knife that is used when cutting is pressed against the cutting edge by hand or by additional spring pressure, to create a sharp cut. The mechanical drive of this well-known Devices can only be done from above the paper support, whereby the free use of the table surface is obstructed.
Die Ausführung des Erfindungsgegenstandes geht von der Erwägung aus, daß der mechanische Antrieb der Schneidevorrichtung von unten her, durch den Schneidschlitz, erfolgen -triuß, wenn der Schrieidtisch, trotz der Schneidevorrichtung, frei und uribehindert sein soll. Auch müßte das Kreismesser stets mit gleichem Druck an der Schneidkante anliegen.The execution of the subject matter of the invention is based on the consideration, that the mechanical drive of the cutting device from below, through the cutting slot, take place -triuß when the writing table, despite the cutting device, is free and should be obstructed. The circular knife should also always apply the same pressure on the The cutting edge.
Diese doppelte Aufgabe wird in einfacher Weise durch die vorliegende Erfindung gelöst, indem zwei dicht beieinander stehende Kreismesser verwendet werden, zwischen denen ein Führungssteg durch den Schneidschlitz zu dem Barunterliegenden Antrieb führt. Durch die Verwendung von zwei Kreismessern wird gegenüber einem Kreismesser ein glatterer Schnitt erzielt. Hierbei sind die Kreismesser so ausgebildet, daß sie mit eigener Spannung an den Schneidkanten anliegen.This dual task is easily accomplished by the present Invention solved by using two circular knives close together, between which a guide bar through the cutting slot to the bar below Drive leads. The use of two circular knives is compared to one circular knife a smoother cut is achieved. Here, the circular knives are designed so that they rest against the cutting edges with their own tension.
Auf der Zeichnung ist ein Ausführungsbeispiel einer Papierschneidevorrichtung nach der Erfindung dargestellt, und zwar zeigen Abb. r eine Gesamtansicht der Vorrichtung und Abb. z einen Mittelschnitt in vergrößertem Maßstab.In the drawing is an embodiment of a paper cutting device Shown according to the invention, namely Fig. R show an overall view of the device and Fig. z shows a central section on an enlarged scale.
Zwei Schienen z sind auf zwei Leisten z derart befestigt, daß ein kleiner Spalt zwischen ihnen verbleibt. Die Leisten z sind in einem größeren Abstand voneinander an den Enden fest miteinander verbunden.Two rails z are attached to two strips z in such a way that a small gap remains between them. The bars z are at a greater distance firmly connected to each other at the ends.
An einem Halter _; sitzen seitlich zwei dünne Kreismesser 4, neben denen außen zwei runde Führungsscheiben 5 sich befinden. Diese-Vorrichtung.ist im Drehpunkt fest miteinander verbunden, bis auf den Halter 3, in dem sich die Achse der Scheiben frei drehen kann.On a holder _; sit on the side two thin circular knives 4, next to which have two round guide washers 5 on the outside. This device is in the Pivot firmly connected to each other, except for the holder 3, in which the axis the discs can rotate freely.
Die dünnen Kreismesser 4 stehen etwas weiter auseinander, als der Schlitz der Schiene r breit ist. Der Halter 3 wird durch den Schlitz gesteckt, wobei die Kreismesser 4 am unteren Rande etwas zusammengedrückt werden und infolgedessen am oberen Schienenrand mit Druck anliegen. Der Halter 3 erhält unterhalb der Schienen zwei seitliche Laschen, die das Herausspringen der Vorrichtung verhindern.The thin circular knives 4 are a little further apart than the The slot of the rail r is wide. The holder 3 is inserted through the slot, wherein the circular knives 4 are slightly compressed at the lower edge and as a result on the upper edge of the rail with pressure. The holder 3 gets below the rails two side tabs to prevent the device from jumping out.
Die dargestellte Vorrichtung sieht für den Antrieb einen Ketten- oder Seilzug vor, der an dem Halter 3 angreift, über Scheiben läuft und mittels Kurbel betätigt wird. Dieser Antrieb kann auch mittels eines kleinen Motors erfolgen.The device shown sees a chain or drive for the drive Cable before which engages the holder 3, runs over disks and by means of a crank is operated. This drive can also be done by means of a small motor.
Die ganze Vorrichtung kann mit den Leisten z an einem Tisch befestigt werden und gestattet somit, Papier, insbesondere Zeichnungen, Lichtpausen u: ä., in beliebigen Längen gerade und scharf in kürzester Zeit zu beschneiden oder zu. trennen.The whole device can be attached to a table with the strips z and thus permits paper, in particular drawings, blueprints, etc., to be cut or cut straight and sharp in any length in the shortest possible time. separate.
