KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Beim Schneiden von Papier, Pappe und anderen Stoffen, die stapelweise aufeinander gelagert dem Schneidmesser zugeführt werden, werden bisher die Abfälle von der Hand entfernt, und da dies nicht nach jedem Schnitte erfolgen kann, so sind sie der Arbeit störend im Wege.When cutting paper, cardboard and other materials that are stacked on top of each other stored to the cutting knife, so far the waste is by hand removed, and since this cannot be done after every cut, they are the work annoying in the way.
Dieser Ubelstand soll nach vorliegender Erfindung dadurch beseitigt werden, daß einThis disadvantage is to be eliminated according to the present invention in that a
ίο Abstreicher angeordnet wird, der mit dem niedergehenden Messer hinter die Abfälle der Schnittfläche gelangt und durch eine Schleuderbewegung die Abfälle von dem Tisch entfernt. ίο scraper is arranged with the descending knife gets behind the waste of the cut surface and by a centrifugal movement removed the waste from the table.
In der beiliegenden Zeichnung ist der .Erfindungsgegenstand veranschaulicht, und zwar zeigen:The subject of the invention is in the accompanying drawing illustrated, namely show:
Fig. ι die Vorderansicht,
Fig. 2 die Seitenansicht undFig. Ι the front view,
Fig. 2 shows the side view and
Fig. 3 eine Einzelheit.Fig. 3 shows a detail.
Gegen den Tisch t hin ist der Messerbalken m beweglich angeordnet und führt sich in dem Maschinengestell /. Bei dem dargestellten Ausführungsbeispiel der Abstreichvorrichtung ist diese mittels unter Federwirkung stehender Bolzen an dem Messerbalken m aufgehängt. Die beiden Arme a tragen eine Welle b, an welcher der Abstreicharm c angebracht ist. An seinem unteren Ende trägt der Abstreicharm eine Anzahl federnder Abstreicher e (in der Darstellung Fig. ι sind vier Abstreicher vorgesehen) , mit welchen er hinter die Abfälle greift, sobald er mit dem Messer niedergeht.The cutter bar m is movably arranged towards the table t and is guided in the machine frame /. In the illustrated embodiment of the scraping device, it is suspended from the cutter bar m by means of bolts under the action of a spring. The two arms a carry a shaft b to which the scraper arm c is attached. At its lower end, the scraper arm carries a number of resilient scrapers e (four scrapers are provided in the illustration in FIG. 1), with which it reaches behind the waste as soon as it goes down with the knife.
Beim Niedergang des Messers wird der Abstreieharm c von einem Daumen f, der federnd an dem Gehäuse d angebracht ist, gezwungen, sich gegen den Messerbalken m hin zu bewegen. Zu diesem Zwecke kann auch eine beliebige andere Einrichtung getroffen werden, ebenso zu der Vorrichtung, die die weitere Bewegung der Abstreicher verursacht. Bei dem dargestellten Ausführungsbeispiel trägt dazu der Abstreieharm c eine Rolle h. When the knife goes down, the scraper arm c is forced by a thumb f, which is resiliently attached to the housing d , to move against the knife bar m. Any other desired device can also be used for this purpose, as well as for the device which causes the further movement of the scrapers. In the illustrated embodiment, the stripping arm c carries a roller h for this purpose.
An dem Maschinengestell ist ein Winkelhebel i schwingend gelagert, der bei niedergehendem Messerbalken durch Vermittlung der Zugstange n, die einerseits an dem Schwingarm k, andererseits an dem Messerbalken m angreift, und durch Vermittlung der Zugstange 0, die am Schwingarm k angreift, eine schwingende Bewegung erhält. Hat der Messerbalken m seinen Niedergang beendet, so wird der freie Arm des Winkelhebeis i auf die Rolle h niedergedrückt, und die Abstreichvorrichtung macht gegen die Wirkung der Federn, auf welche sie sich stützt, eine weitere Abwärtsbewegung (einpunktiert gezeichnet, Fig. 2), bis der Daumen / über den Ansatz des Abstreichers c gleitet und in seine Anfangsstellung zurückfedert. An angle lever i is mounted to swing on the machine frame and when the cutter bar descends, it creates a swinging movement by means of the pull rod n, which engages on the one hand on the swing arm k and on the other hand on the cutter bar m , and by means of the pull rod 0, which engages the swing arm k receives. When the cutter bar m has finished its descent, the free arm of the angle jack i is pressed down onto the roller h , and the scraper makes a further downward movement against the action of the springs on which it rests (shown in dotted lines, Fig. 2), until the thumb slides over the base of the scraper c and springs back into its starting position.
Nunmehr wird auch der freigegebene Abstreicher c unter Wirkung einer Feder ρ nach hinten zurückschnellen und die abgeschnittenen Abfälle von dem Tisch schleudern. The released scraper c will now also snap backwards under the action of a spring ρ and hurl the cut waste from the table.
Mit aufsteigendem Messer werden alle Teile wieder in ihre Anfangsstellung zurückgeführt. With the knife rising, all parts are returned to their starting position.
Dem Abstreicher c wird eine kleine Eigenbewegung gegen die Wirkung seiner FedernThe scraper c has a small movement of its own against the action of its springs
gegeben, weil er zunächst hinter dem Messer zurückbleiben muß, damit jede Klemmung beim Schnitt vermieden wird. Sobald aber der Schnitt erfolgt ist, muß der Abstreicher nacheilen. Hierzu erhält er die vorbesprochene Eigenbewegung.given because he has to stay behind the knife first, so that any jamming is avoided when cutting. But as soon as the cut has been made, the scraper must lag behind. For this he receives the previously discussed own movement.
