Description
Schwenkbarp Querschneidevorrichtung für laufende Papierbahnen Das Patent 467 63 i beschreibt eine schwenkbare Querschneidevorrichtung für laufende Papierbahnen mit einer Einstellvorrichtung für den Querschneider in eine beliebige Schräglage zur Querachse der Papierlaufrichtung während des Betriebes, wobei der Drehpunkt für die schwenkbare Querschneidevorrichtung in eine Linie verlegt ist, die in senkrechter Richtung die beiden Achsen der Antriebszahniräder in. der Mitte der miteinanderkämmenden Radzähne schneidet. Nach der Erfindung wird die Anordnung der Schwenkvorrichtung dadurch weiter vervallkomrnnet; da@ß die Achsen der Antriebszaftniräder nicht mehr in: der -gleichen senkrechten Ebene liegen, sondern in die gleiche oder annähernd gleiche wagerechte Ebene gelegt werden. .Swiveling cross cutting device for running paper webs Patent 467 63 i describes a pivoting cross cutter for running Paper webs with an adjustment device for the cross cutter in any Inclined position to the transverse axis of the paper running direction during operation, the The pivot point for the swiveling cross-cutting device is laid in a line, in the vertical direction the two axes of the drive gears in the middle the meshing gear teeth cuts. According to the invention, the arrangement the pivoting device thereby further vervallkomrnnet; da @ ß the axles of the drive pinion wheels no longer lie in: the same vertical plane, but in the same or approximately the same horizontal plane can be placed. .
Hierdurch ist *es in vorteilhafter Weise möglich, den Drehpunkt für die Querschneidevorrichtung auch unterhalb des auf der Messertrommel sitzenden Antriebszahnrades anzuordnen. Vor allen Dingen ergibt sich aber gemäß der neuen: Anordnung der Vorteil, daß beim Verschwenken der Antriebszahnräder zueinander diese nicht' mehr in Richtung ihrer Zahnflanken, sondern parallel zu diesen verstellt werden, wodurch sich ein größerer Schwenkbereich und eine Schonung der Radzähne ergibt.This * makes it possible in an advantageous manner, the pivot point for the cross cutting device also below the drive gear seated on the cutterhead to arrange. But above all, according to the new: arrangement the advantage, that when pivoting the drive gears to each other these no longer 'in the direction their tooth flanks, but can be adjusted parallel to these, creating a larger swivel range and a protection of the wheel teeth results.
Auf der Zeichnung ist eine beispielsweise Ausführungsform der Erfindung in Abb. i in Seitenansicht und.in Abb. a in Kopfansicht dargestellt.The drawing shows an example embodiment of the invention in Fig. i in side view and in Fig. a in top view.
Abb.3 und q. zeigen Draufsichten bei verschiedener Stellung der Teile.Fig.3 and q. show top views with the parts in different positions.
Abb. 5 bis 9 zeigen Zahnformen, wie sie zur Ermöglichung der Verstellung der Querschneiderachsen Verwendung finden.Figs. 5 to 9 show tooth shapes as they are used to enable adjustment the cross cutter axes are used.
Wie beim Hauptpatent liegt der Drehzapfen 8 in einer Ebene senkrecht zur Mitte der Zähne des auf der Messertrommel 3 sitzenden Antriebszahnrades 1q.. Es ist dabei ohne Belang, ob der Drebzapfen innerhalb des dann topfartig gestalteten Antriebsrades oder .außen, also oberhalb oder unterhalb des Rades,. angeordnet wird. Das Antriebsrad i i ist seitlich des Rades i q. gelagert, wobei die Radachsen in der gleichen oder annähernd gleichen wagerechten Ebene angeordnet werden. Gegebenenfalls kann die Achse des Rades i i aber auch schräg zur Trommelachse liegen. Das Hauptantriebsrad i z kämmt an beliebiger Stelle in das Rad i-i.As in the main patent, the pivot 8 is perpendicular in a plane to the middle of the teeth of the drive gear 1q .. sitting on the cutterhead 3. It is irrelevant whether the pivot pin is inside the pot-like shape Drive wheel or outside, i.e. above or below the wheel. is arranged. The drive wheel i i is to the side of the wheel i q. stored, with the wheel axles in the same or approximately the same horizontal plane are arranged. Possibly but the axis of the wheel i i can also be inclined to the drum axis. The main drive wheel i z meshes with the wheel i-i at any point.
Wird die Querschneidevorrichtung aus der Stellung der Abb.3, in die Stellung nach Abb. q. verschwenkt, dann verschieben sich die Zähne der Räder i i und i q. parallel zu den Zahnflanken, so daß beim Antrieb der Messertrommel trog der konvergierenden Lage der Radachsen zueinander keine ungünstige Beanspruchung der Radzähne eintritt., Letztere können auch (im Querschnitt des Radkörpers) bogenförmig gestaltet bzw. mit seitlichen Abschrägungen am Zahngrunde versehen sein, wie die Abbildungen erkennen lassen.If the cross-cutting device is moved from the position of Fig Position according to fig. Q. pivoted, then move the teeth of the wheels i i and i q. parallel to the tooth flanks, so that the cutterhead trough when driving the converging position of the wheel axles to each other no unfavorable stress the wheel teeth enters., The latter can also (in the cross-section of the wheel body) arc-shaped designed or provided with side bevels on the tooth base, like the Allow images to be recognized.
