Patentirt im Deutschen Reiche vom 24. Juni 1880 ab.Patented in the German Empire on June 24, 1880.
Diese Einrichtung bezieht sich auf die Zuleitung des zu schneidenden Papieres zur Mefstrommel, welche bei Querschneidmaschinen in Anwendung kommt.This device relates to the supply of the paper to be cut to the measuring drum, which is used in cross cutting machines.
Die Mefstrommel, über welche das zu schneidende Papier läuft, hat eine, der Bogenlänge entsprechende, oscillirende Bewegung. Bei der Vorwärtsbewegung zieht dieselbe das Papier um die Bogenlänge vorwärts, dasselbe wird sodann festgehalten und abgeschnitten, . während die Trommel ihren Rückgang macht. Damit das Papier während der Vorwärtsbewegung auf der Trommel nicht gleitet, wird es derselben durch zwei über einander liegende Walzen zugeführt. Die Geschwindigkeit dieser Zuführungswalzen mufs der jeweiligenBogenlänge genau entsprechen, und wird dieselbe bei den seitherigen Maschinen durch zwei konische Trommeln, die durch einen verschiebbaren Riemen mit einander verbunden sind, von Hand regulirt. Die Zuführungswalzen werden im vorliegenden Falle derart von der Mefstrommel getrieben, dafs sich die Geschwindigkeit derselben selbstthätig regulirt und sie stets der Bogenlänge entspricht, eine Regulirung von Hand daher nicht mehr nöthig ist.The measuring drum, over which the paper to be cut runs, has an arc length corresponding, oscillating movement. As it moves forward, it moves the paper the arc length forward, the same is then held and cut off,. while the Drum makes its decline. So that the paper moves forward on the Drum does not slide, it is fed to the same by two superposed rollers. The speed of these feed rollers must correspond exactly to the respective sheet length, and in the machines of that time it becomes the same by two conical drums, which are connected by one slidable straps are connected to each other, regulated by hand. The feed rollers are in the present case driven by the measuring drum in such a way that the speed increases it regulates itself automatically and it always corresponds to the arc length, a regulation is therefore no longer necessary by hand.
Auf der Welle der Mefstrommel, oder mit derselben durch ein Paar Räder verbunden, sitzt eine Riemscheibe, die also eine, der Mefstrommel genau entsprechende, oscillirende Bewegung macht. Diese oscillirende Bewegung wird vermittelst eines Riemens auf die lose Riemscheibe«, Fig. 3 und 4, übertragen, welche mit zwei Sperrrädern b und/ in Verbindung steht. Das Sperrrad b wird von der losen Scheibe α mitgenommen, wenn sich dieselbe in der Richtung des Pfeiles bewegt, und treibt die Zuführungswalze vermittelst der Zahnräder c, d und e, wovon e auf der Welle der unteren Zuführungswalze fest sitzt, in derselben Richtung, wie sich die Scheibe α bewegt. Das Sperrrad f wird mitgenommen, wenn sich die Scheibe α in der entgegengesetzten Richtung bewegt, und treibt die Zuführungswalze vermittelst der Räder g und h in derselben Richtung, wie vorher, so dafs sich die Zuführungswalzen sowohl beim Vorwärtsgang als auch beim Rückgang der Mefstrommel Papier zuführen. Es ist klar, dafs die Quantität des ■ zugeführten Papieres stets der Gröfse der Oscillationen der Mefstrommel, das ist der Bogenlänge, entspricht.On the shaft of the Mefstrommel, or connected to it by a pair of wheels, sits a pulley, which therefore makes an oscillating movement that corresponds exactly to the Mefstrommel. This oscillating movement is transmitted by means of a belt to the loose belt pulley, FIGS. 3 and 4, which is connected to two ratchet wheels b and /. The ratchet wheel b is driven by the loose disk α when it moves in the direction of the arrow, and drives the feed roller by means of the gears c, d and e, of which e is firmly seated on the shaft of the lower feed roller, in the same direction as the disk α moves. The ratchet wheel f is taken along when the disk α moves in the opposite direction, and drives the feed roller by means of the wheels g and h in the same direction as before, so that the feed rollers feed each other with paper both when moving forward and when the drum is falling . It is clear that the quantity of paper fed in always corresponds to the magnitude of the oscillations of the measuring drum, that is, the length of the sheet.
