Description

Maschine zum Beschneiden von. Blätterstapeln und Büchern mit mehreren sich kreuzenden IVdessern Es ist bei Papierschneidemaschinen mit einem Messer bekannt, daß man das Messer durch konvergierende Schlitze oder andere Mittel so führen kann, daß es zunächst den Stapel schräg anschneidet und sich während des Schnitts so weit dreht, daß seine Schneide nach vollendetem Schnitt parallel zur Schneidunterlage liegt. Es ist auch bei Maschinen mit mehreren schwingenden oder geradlinig bewegten Messern bekannt, daß die Messer so bewegt werden, daß ihre Schneiden nach vollendetem Schnitt parallel zur Schneidunterlage liegen, so daß keine Gegenkanten. für die Messer erforderlich sind.Machine for trimming. Stacks of leaves and books with several intersecting desserts It is known in paper cutting machines with a knife that the knife can be guided through converging slots or other means in such a way that it first cuts the stack at an angle and then rotates during the cut so far that its cutting edge after completion of S chnitt is parallel to the cutting surface. It is also known in machines with several knives that oscillate or move in a straight line that the knives are moved in such a way that their cutting edges are parallel to the cutting base after the cut has been completed, so that there are no opposing edges. for which knives are required.

Diesem Bekannten gegenüber besteht die Neuerung darin, daß die Messer bei Maschinen mit mehreren Messern so geführt werden, daß sie einerseits den Stapel schräg anschneiden und daß andererseits die Schneiden aller Messer nach beendetem Schnitt parallel zur Schneidunterlage liegen. Hierdurch wird bei ein und derselben Maschine der an sich bekannte Vorteil, der in dem schrägen Anschnitt des Stapels liegt, mit dem ebenfalls bekannten Vorteil vereinigt, daß Gegenkanten für die Messer erspart werden.Compared to this acquaintance, the innovation is that the knives in machines with several knives are guided so that they on the one hand the stack cut obliquely and that on the other hand the cutting of all knives after finished Cut parallel to the cutting board. This is one and the same Machine the per se known advantage, which is in the inclined gate of the stack is, combined with the also known advantage that counter edges for the knife be saved.

In der Zeichnung ist ein Ausführungsbeispiel der Neuerung dargestellt.In the drawing, an embodiment of the innovation is shown.

Abb. i ist eine Seitenansicht des Oberbaues der Maschine mit den Trägern 6 der Seitenmesser i in höchster Stellung. Abb. z entspricht der Abb. i in Vorderansicht, wobei der Träger des Vordermessers a fortgelassen ist. Abb.3 ist eine Seitenansicht mit den Trägern 6 der Seitenmesser i in tiefster Stellung. Abb. 4. entspricht der Abb. 3 in Vorderansicht mit auseinandergestellten Messerträgern 6.Fig. I is a side view of the superstructure of the machine with the girders 6 the side knife i in the highest position. Fig. Z corresponds to Fig. I in front view, the carrier of the front knife a is omitted. Fig.3 is a side view with the carriers 6 of the side knife i in the lowest position. Fig. 4. corresponds to the Fig. 3 in front view with knife carriers 6 apart.

Die Achse 8 ist an beiden Seiten mit Bolzen 9 versehen, welche in einer in der Gestellwand ii angebrachten Gleitbahn io geführt sind. An den aus der Gestenwand i i herausragenden Teilen der Bolzen 9 greifen die Zugstangen 7 an, welchen in bekannter Weise vom Antriebsmechanismus der Maschine eine auf- und abwärts gehende Bewegung verliehen wird. Auf der Schwingachse 8 ist ein Hebel 3 fest angeordnet. Das andere Ende dieses Hebels 3 ist vermittels des Bolzens 1a in einer schrägen Gleitbahn 13 der Gestellwand i i geführt. Die Gleitbahn 13 ist um einen bestimmten Winkel gegenüber der Gleitbahn io geneigt angeordnet, so daß der Schwingachse 8 und. somit den Messerträgern 6 beim Auf- und Abwärtsgang der Zugstange 7 eine schwingende Bewegung verliehen wird. Dadurch wird erreicht, daß die an den Trägern 6 befestigten Seitenmesser i den Stapel ¢ nicht parallel zu seiner Oberfläche, sondern von einer Seite aus schräg anschneiden, so daß die Messer allmählich in den Stapel q. von vorn nach hinten eindringen, wodurch ein Verschieben der Stapelblätter während des Schnitts vom Anschlagwinkel s hinweg erschwert wird. Weiterhin tritt auch beim Einschnitt der Seitenmesser i in den Stapel kein Stoß auf, da die Messer nicht auf der ganzen Linie in den Stapef eindringen. Der Schnitt der Seitenmesser erfolgt fast geräuschlos.The axis 8 is provided on both sides with bolts 9, which are guided in a slide track io mounted in the frame wall ii. On the parts of the bolts 9 protruding from the gesture wall ii, the tie rods 7 engage, which, in a known manner, are given an upward and downward movement by the drive mechanism of the machine. A lever 3 is fixedly arranged on the oscillating axis 8. The other end of this lever 3 is guided by means of the bolt 1a in an inclined slide 13 of the frame wall ii. The slide 1 3 is inclined at a certain angle relative to the slide io, so that the swing axis 8 and. thus the knife carriers 6 is given an oscillating movement during the upward and downward movement of the pull rod 7. It is thereby achieved that the side knives i attached to the supports 6 cut the stack ¢ not parallel to its surface, but at an angle from one side, so that the knives gradually enter the stack q. penetrate from the front to the back, which makes it difficult to move the stacking sheets away from the stop angle s during the cut. Furthermore, when the side knives i cut into the stack, there is no impact, since the knives do not penetrate the stack along the whole line. The cutting of the side knives is almost noiseless.
