Description

Längsschneidevorrichtung  Slitter
Beschreibung description
Die vorliegende Erfindung betrifft eine Vorrichtung zum Längsschneiden von Materialbahnen und/oder Materialbogen nach dem Oberbegriff des Anspruchs 1 . Zum Längsschneiden insbesondere von Pappenbogen sind Pappenkreisscheren bekannt, welche sich über die Maschinenbreite erstreckende Schneidwellen aufweisen. Auf diesen sind die einzelnen Kreismesser mehrerer Kreisscheren mittels Klemmung befestigt. Die Schneidwellen sind permanent mittels Getriebe mit einem steuerbaren Motor antriebsverbunden. Der Transport des Schneidgutes innerhalb des Schneidwerkes erfolgt durch die Umfangsgeschwindigkeit der Kreismesser. The present invention relates to a device for longitudinal cutting of material webs and / or material sheets according to the preamble of claim 1. Cardboard scissors are known for longitudinal cutting, in particular paperboard sheets, which have cutting shafts extending across the machine width. On these the individual circular knives of several circular shears are fixed by means of clamping. The cutting shafts are permanently drive-connected by means of a gearbox with a controllable motor. The transport of the material to be cut within the cutting unit is done by the peripheral speed of the circular blade.
Durch Lösen ihrer Klemmung, Verschieben der Kreismesser einer Kreisschere und anschließendem Festsetzen, kann die Schnittposition über der Breite des Schneidgutes verändert werden. Dabei muss jedes Kreismesser einzeln By loosening their clamping, moving the circular blade of a circular shear and then setting, the cutting position can be changed over the width of the material to be cut. Each circular knife must be individual
Positioniert werden, insbesondere ist auf das Anstellen von Ober- und Be positioned, in particular is on the hiring of upper and
Untermesser derselben Kreisschere zu achten, um einerseits einen sauberen Schnitt zu erzeugen, andererseits aber einen übermäßigen Verschleiß der Kreismesser zu vermeiden. Bei gesteigerter Anforderung an die Maßhaltigkeit der zu erzeugenden Zuschnitte ist dieses manuelle Rüsten entsprechend aufwendig und fehleranfällig.  Pay attention to the lower blade of the same circular shear, on the one hand to produce a clean cut, on the other hand, to avoid excessive wear of the circular blade. With increased demand on the dimensional accuracy of the blanks to be produced, this manual setup is correspondingly expensive and error-prone.
Die Schnittkräfte werden neben der Geometrie der einzelnen Schneiden maßgeblich von der Überschneidung der Kreismesser eines Paares bestimmt. Diese Überschneidung wird über den Abstand der Schneidwellen eingestellt. Die Überschneidung der auf demselben Schneidwellenpaar angebrachten The cutting forces are determined not only by the geometry of the individual cutting edges, but also by the intersection of the circular knives of a pair. This overlap is set by the distance of the cutting shafts. The overlap of mounted on the same cutting shaft pair
Kreisscheren kann nur gemeinschaftlich erfolgen. Dies vereinfacht eine Circular shears can only be done jointly. This simplifies one
Gesamtverstellung der Überschneidung, um die Vorrichtung auf unterschiedliche Eigenschaften des Schneidgutes einzustellen. Eine auf die einzelne Kreisschere wirkende individuelle Korrektur ist aber nicht möglich. Die Kreisscheren können derart dicht benachbart angeordnet sein, dass sich deren Klemmungen berühren und aus den Bogen Streifen von wenigen Overall adjustment of the overlap to adjust the device to different properties of the material to be cut. However, an individual correction acting on the individual circular shear is not possible. The circular shears can be arranged so close together that touch their clamps and out of the bow strips of a few
Zentimeter Breite geschnitten werden können. Um die möglichen Centimeters wide can be cut. To the possible
Schnittpositionen nicht einschränken zu müssen und den Rüstaufwand bei Veränderung der Schnittpositionen gering zu halten, sind die Bauräume der zu- und abführenden Transportsysteme von dem Schneidwerk strikt getrennt. Der Vorschub des Schneidgutes innerhalb des Schneidwerkes erfolgt damit lediglich durch die angetriebenen Kreisscheren. Damit ist die kleinstmögliche Bogenlänge im Wesentlichen durch die Durchmesser der eingesetzten Kreismesser bestimmt. Dagegen nimmt die Schnittqualität mit steigendem Durchmesser der Kreismesser aufgrund der besseren Führungseigenschaften zu. Darüber hinaus ermöglichen größere Durchmesser der Kreismesser eine steifere Auslegung des To not have to restrict cutting positions and to keep the setup effort low when changing the cutting positions, the space of the incoming and outgoing transport systems are strictly separated from the cutting unit. The feed of the material to be cut within the cutting unit is thus carried out only by the driven circular shears. Thus, the smallest possible arc length is essentially determined by the diameter of the circular blade used. In contrast, the cutting quality increases with increasing diameter of the circular blade due to the better guiding properties. In addition, larger diameter circular knives allow a stiffer design of the
Schneidwerkes, was sich wiederum vorteilhaft auf die Schnittqualität auswirkt. Heutige Pappenkreisscheren stellen damit immer einen Kompromiss zwischen guter Schnittqualität und kleinstmöglicher Bogenlänge dar. Cutting unit, which in turn has an advantageous effect on the quality of cut. Today's cardboard circular scissors always represent a compromise between good cut quality and the smallest possible arc length.
Es ist daher eine Aufgabe der vorliegenden Erfindung, eine gegenüber dem Stand der Technik verbesserte Vorrichtung zu schaffen, welche die Schnittqualität zumindest für kurze Bogen verbessert. It is therefore an object of the present invention to provide a device which is improved over the prior art and which improves the quality of cut, at least for short bends.
Die Erfindung löst die Aufgabe durch eine Vorrichtung mit den Merkmalen des Patentanspruchs 1 . Vorteilhafte Weiterbildungen der Erfindung sind durch die in den Unteransprüchen angegebenen Merkmale gekennzeichnet. The invention achieves the object by a device having the features of patent claim 1. Advantageous developments of the invention are characterized by the features specified in the subclaims.
