Description
DEUTSCHESGERMAN
Die Erfindung betrifft eine Schneidvorrichtung an Formatwalzen von Pappenmaschinen. Die bisher bekannten Einrichtungen dieser Art bestehen aus einem im Inneren der Formatwalze angeordneten Schermesser, das nach Erreichen der gewünschten Schichtdicke des Pappenwickels aus der Formatwalze herausschnellt und den Wickel stellenweise aufwölbt, sowie aus einer mit dem Messer der Formatwalze scherenden Gegenwalze. Diese Gegenwalze ist mit einer Längsnut für den Eintritt des aus der Formatwalze herausschnellenden Messers versehen, wobei der Pappenwickel in ziehendem Schnitt durchtrennt wird. Diese bekannte Einrichtung hat jedoch den Nachteil, daß die Gegenwalze immer synchron mit der Formatwalze laufen muß, damit das nach Erreichen der gewünschten Schichtdicke des Pappenwickels aus der Formatwalze herausschnellende Messer genau in die Längsnut der Gegenwalze eintritt und den Wickel durchschneidet.The invention relates to a cutting device on format rollers of cardboard machines. The ones known so far Devices of this type consist of a shear knife arranged inside the format roller, which snaps out of the format roller after the desired layer thickness of the cardboard roll has been reached and the roll bulges in places, as well as from one sheared with the knife of the format roller Counter roll. This counter roller has a longitudinal groove for the entry of the format roller provided with a popping knife, whereby the cardboard roll is severed in a pulling cut. However, this known device has the disadvantage that the counter roller is always synchronous with the format roller must run so that after reaching the desired layer thickness of the cardboard roll from the The knife that snaps out of the format roller enters the longitudinal groove of the counter roller and the roll cuts through.
Die Erfindung bezweckt, derartige Schneidvorrichtungen zu vereinfachen und zu verbilligen, und zwar besteht die Erfindung darin, daß die Gegenwalze nicht als Nutwalze, sondern als Messerwalze ausgebildet ist. Eine Synchronisierung des Umlaufs der Gegenwalze mit der Formatwalze ist nicht mehr erforderlich, so daß sich die Anlage bedeutend vereinfacht und verbilligt.The aim of the invention is to simplify such cutting devices and to make them cheaper the invention consists in that the counter roller is not designed as a grooved roller, but as a knife roller is. It is no longer necessary to synchronize the rotation of the counter roller with the format roller. so that the system is significantly simplified and cheaper.
Es ist zwar ferner bereits bekannt, beim Querschneiden von Papierbahnen od. dgl. die Bahn am Sammelplatz auf einen zylindrischen Träger mit einem der gewünschten Schnittlänge entsprechenden Umfang aufzurollen, dort festzuhalten und zu zerschneiden. Der Papierträger ist dabei mit einem starr an ihm befestigten Messer ausgerüstet, welches mit einem außerhalb desselben befindlichen rotierenden Gegenmesser abscherend zusammenarbeitet. Auch bei dieser Einrichtung ist Voraussetzung, daß der Papierträger und die Gegenmesserwalze synchron laufen, damit im Augenblick des Schnittes beide Messer zur Wirkung gelangen. Bei der erfindungsgemäßen Einrichtung dagegen, die sich außerdem auf Formatwalzen von Pappenmaschinen bezieht, kann die als Messerwalze ausgebildete Gegenwalze unabhängig von der Drehzahl der Formatwalze umlaufen, da sie mit dem Schermesser der Formatwalze nicht unmittelbar, sondern nur mittelbar zusammenwirkt, indem sie beim Hervorschnellen des letzteren aus der Formatwalze nur über die hierbei erzeugte Auswölbung hinwegstreicht und dabei die Pappenschicht über dem Messer der Formatwalze abschert.Although it is also already known, od when cross-cutting paper webs. Like. The web on Assembly point on a cylindrical carrier with a length corresponding to the desired cutting length Roll up the circumference, hold it there and cut it. The paper carrier is rigid with one equipped on it attached knife, which is located with a rotating outside of it Counter knife cooperates shearing. With this device, too, it is a prerequisite that the paper carrier and the counter knife roller run synchronously, so that both knives take effect at the moment of the cut. In the device according to the invention on the other hand, which also refers to format rollers of cardboard machines, can be used as Knife roller trained counter roller rotate independently of the speed of the format roller, since they not directly, but only indirectly interacts with the cutter of the format roller by when the latter shoots out of the format roller, they only use the bulge created in this way sweeps away and shears off the cardboard layer over the knife of the format roller.
Die Erfindung wird nachstehend an Hand der Zeichnung näher erläutert. Es stellen dar:The invention is explained in more detail below with reference to the drawing. They represent:

The knife roller c rotates on the circumference of the format roller d. If the shear blade b is now snapped out of the format roller after the desired cardboard thickness has been reached, the blade of the blade roller c performs a scissor stroke on the blade caused by the shear blade /; caused bulge and cuts through the winding, which arrives in the form of an arc down on a support felt e and is carried away through it. As is known, the felt is equipped with a suction device / which sucks the cardboard sheet from the format roller and transfers the support felt e.
