Description

Einstellvorrichtung für das bewegliche Messer an Pappscheren. Um das Oben-riesser gegen das Untermesser bei Pappsche-ren anstellen zu können, hat man bisher auf dem als Drehzapfen benutzten Bolzen ein-en beiderseits von einem Doppellagerarm des Maschinengestelles umfaßten Stellring festgeklenunt. Dieses bedingt eine an dem großen Gußstück schwierig auszuführende Bearbeitung und Paßarbeit und auch eine Schwächung des am stärksten beanspruchten Tei#les der Maschine. Die Erfindung sieht ein ganz geschlossenes, mit einer glatten Bohrung versehenes Lagerauge vor, in das der Messerbolzen, der mit zwei Anlageschultern für einen dazwischenliegenden, um den Bolzen drehbaren Stellring versehen ist, eingesetzt wird, worauf nach der richtigen Messeranstellung der Stellring mit einer Schraube im Lagerauge festgeklemmt wird.Adjustment device for the movable knife on cardboard scissors. To that You have to be able to use top rippers against the bottom knife on paper scissors hitherto on the bolt used as a pivot on both sides of a double bearing arm of the machine frame included the collar festgeklenunt. This requires a the large casting difficult machining and fitting work and also a Weakening of the most heavily used part of the machine. The invention sees a completely closed bearing eye with a smooth bore into which the knife bolt, the one with two contact shoulders for one in between the bolt rotatable collar is provided, is used, whereupon after the correct Knife adjustment the collar is clamped with a screw in the bearing eye.

In nachfolgendem ist die Erfindung beschrieben und in einer Zeichnung dargestellt. Dabei -ist alles das fortgelassen, was für das Verständnis der Erfindung nicht erforderlich und bekannt ist.The invention is described below and in a drawing shown. Everything that is necessary for an understanding of the invention has been omitted not required and known.

Es zeigt die Abbildung einen Querschnitt durch das Auge am Maschinengestell, in welchem der Bolzen des beweglichen Obermessers gegen seitliche Verschiebung nachstel-lbar und frei drehbar gehalten wird.The figure shows a cross-section through the eye on the machine frame, in which the bolt of the movable upper knife can be readjusted against lateral displacement and is held freely rotatable.

Der Messerhalter i, welcher das Obermesser trägt, ist in bekannter Weise mit dem Bolzen 2 fest verbunden. Der Bolzen 2 Soll in dem Maschinengestell 3 achsial anstellbar sein, in der richtigen Stellung dann aber gegen seitliche Verschiebung gesichert werden. Dabei soll er frei drehbar in dem Maschinengestell 3 sein. Der Bolzen 2 trägt eine Büchse 4, welche durch einen Stift 5 mit dem Bolzen 2 fest verbunden ist, und zwar ist der Außendurchmesser der Büchse` 4 vorteilhafterweise der gleiche wie der starke Bund das Bolzens 2. Zwischen dem Bund des Bolzens 2 und der BÜchse 4 ist eine Büchse 6 eingepaßt, welche seitlich auf dem Bolzen ilicht verschiebbar ist, welche aber um iden Bolzen z als auch im Gehäuse 3 leicht drehbar ist. - Die Büchse 6 kann mit einer im Maschinengestell 3 vorgesehenen Schraube 7 festgeklemmt werden.The knife holder i, which carries the upper knife, is firmly connected to the bolt 2 in a known manner. The bolt 2 should be axially adjustable in the machine frame 3 , but then secured against lateral displacement in the correct position. It should be freely rotatable in the machine frame 3 . The bolt 2 carries a sleeve 4, which is firmly connected to the bolt 2 by a pin 5 , namely the outer diameter of the Büchse` 4 is advantageously the same as the strong collar of the bolt 2. Between the collar of the bolt 2 and the sleeve 4, a bush 6 is fitted, which can be shifted laterally on the bolt, but which can easily be rotated around the bolt z as well as in the housing 3. - The sleeve 6 can be clamped with an opening provided in the machine frame 3 screw. 7

Beim Einstellen des Obermessers löst man die Schraube 7, drückt in bekannter Weise das Obennesser gegen das Untermesser, wobei sich. der Bolzen 2 mit der Büchse 4 und der Büchse 6 achsial verschiebt, klemmt in der gewünschten Stellung die Büchse 6 mit der Schraube 7 fest, und das Obermesser ist drebar, aber achsial nicht verschiebbar einwandfrei geführt und gelagert. Dadurch, daß die Büchse 4 und, der Bolzen 2 die gleichen Außendurchmesser haben, genügt eine glatte Bohrung im Maschinengest#-,U 3 zur Aufnahme des vorher fertig montierten Bolzens 2 mit den Büchrsen 4 und 6, so daß in der Bearbeitung -sowohl einfache- Operationen möglich sind, als auch eine Montage ohne Nachpaßarbeiten durchgeführt werden kann. Die neue Einrichtung bedeutet also# eine wichtige wirtschaftliche Verbesserung.When adjusting the upper knife you loosen the screw 7, presses the upper knife against the lower knife in a known manner, whereby. the bolt 2 with the sleeve 4 and the sleeve 6 moves axially, clamps the sleeve 6 in the desired position with the screw 7 , and the upper knife is rotatable, but not axially displaceable properly guided and stored. Because the sleeve 4 and the bolt 2 have the same outer diameter, a smooth bore in the machine frame is sufficient -, U 3 to accommodate the previously assembled bolt 2 with the sleeves 4 and 6, so that in the machining -both simple - Operations are possible, as well as assembly can be carried out without re-adjustment work. The new facility means # an important economic improvement.

Konstruktiv ist die Schaffung der seitlichen Widerlager für die Büchse 6 auch anders möglich. Beispielsweise könnte an Si:elle der Büchse 4 eine Scheibe gegen den Bolzen 2 geschraubt werden. Auch könnte an Stelle der geschlossenen Büchse 6 eine geschlitzte Büchse gewählt werden, welche durch die Schraube 7 gespreizt wird.In terms of construction, the creation of the lateral abutments for the bush 6 is also possible in a different way. For example, a washer could be screwed against the bolt 2 at the bottom of the bushing 4. Instead of the closed bush 6, a slotted bush could also be selected, which is spread apart by the screw 7.
