Abstract
Description
Die Erfindung betrifft eine Vorrichtung zum Durchtrennen von Papier und/oder Kunststofffolien sowie anderen, dünnwandigen Werkstoffen mit Hilfe einer Schneidwalze und einer Gegenwalze, die parallel zueinander in einem Maschinengestell gelagert sowie angetrieben sind, wobei der Schneidspalt zwischen Schneidwalze und Gegenwalze grundsätzlich veränderbar ist. Vor allem sehr dünne Papiere und oft auch Kunststofffolien erfordern einen Schneidspalt von weniger als 5 μm zwischen dem Schneidendach und der Gegenwalze, so dass eine Durchdringung des zu durchtrennenden Teiles von mehr als 95% erreicht wird.The The invention relates to a device for severing paper and / or plastic films and other, thin-walled materials Help a cutting roller and a counter roll, which are parallel to each other stored and driven in a machine frame, wherein the cutting gap between cutting roller and counter-roller basically changeable is. Especially very thin Papers and often also plastic films require a cutting gap of less than 5 μm between the cutting roof and the counter roll, so that a penetration of the reached to be cut part of more than 95%.
Vorrichtungen
zum Durchtrennen und/oder zum Anstanzen von Papieren aller Art,
wie z. B. auch bei der Herstellung von Briefumschlägen, von
Etiketten oder sonstigen Produkten auf Trägermaterialien mit der Möglichkeit
zum Einstellen des Schneidspaltes sind grundsätzlich bekannt. Dazu gehört auch eine
Stanzvorrichtung gemäß der
Aufgrund der gewählten Konstruktion ist die Position der Mittel- und/oder Lagerachse des Gegendruckzylinders verstellbar. Je nach Winkelstellung der Lagerachse ändert sich der Schneidspalt und damit die Schneidebene wie auch die Arbeitshöhe des Gegendruckzylinders. Die tragende Achse des Stanzzylinders ist starr, wobei an Druckstücken angeordnete Druckrollen am Umfang des Stanzzylinders angreifen und mindestens ein Druckstück z. B. mit Hilfe eines Handrades derart bewegbar ist, dass die Druckrollen auf Schmitzringe an dem Stanzzylinder drücken. Die Schmitzringe sind wiederum an dem Gegendruckzylinder in vertikaler Richtung durch die Lagerung des Gegendruckzylinders gehalten.by virtue of the chosen one Construction is the position of the center and / or bearing axis of the Counter-pressure cylinder adjustable. Depending on the angular position of the bearing axis changes the cutting gap and thus the cutting plane as well as the working height of the impression cylinder. The supporting axis of the punching cylinder is rigid, being arranged on pressure pieces Pressure rollers on the circumference of the punching cylinder attack and at least a pressure piece z. B. is movable by means of a handwheel so that the pressure rollers Press on bearer rings on the punching cylinder. The bearer rings are turn on the impression cylinder in the vertical direction kept the storage of the impression cylinder.
Das Arbeitsprinzip und Konzept dieser bekannten Stanzvorrichtung sind nicht unkompliziert und aufwändig, soweit dies die Antriebe und Verstellwellen betrifft. Insbesondere verändert sich die wirksame Schneidebene und mit der exzentrischen Bewegung des Gegendruckzylinders die Arbeitshöhe.The Working principle and concept of this known punching device are not uncomplicated and time-consuming, as far as the drives and adjusting shafts are concerned. Especially changed the effective cutting plane and with the eccentric movement the impression cylinder the working height.

Der Erfindung liegt daher die Aufgabe zugrunde, eine Vorrichtung zum Durchtrennen der hier interessierenden Werkstoffe zu schaffen, wobei der technische Aufwand deutlich geringer ist als beim Stand der Technik und es dennoch möglich ist, Papiere aller Art und/oder Folien gegebenenfalls auch nur anzustanzen oder sonstige Produkte auf Trägermaterialien mit unterschiedlichen Dicken durch die Einstellung des Schneidspaltes zu bearbeiten. Auch eine Reduzierung und Einstellbarkeit der Schnittkräfte zur Verringerung des Werkzeugverschleiß sind ebenso erwünscht, wie eine konstante Lage des Gegendruckzylinders.Of the Invention is therefore based on the object, a device for To cut through the materials of interest here, wherein the technical complexity is significantly lower than in the prior Technique and still possible is, if necessary, only to punch papers of all kinds and / or slides or other products on substrates with different thicknesses through the adjustment of the cutting gap to edit. Also, a reduction and adjustability of the cutting forces to Reduction of tool wear is also desired, as is a constant position of the impression cylinder.
Zur Lösung dieser Aufgabe sieht die Erfindung mit den Merkmalen des kennzeichnenden Teiles von Patentanspruch 1 vor, dass die Schneidwalze über ihre Lagerzapfen unmittelbar angetrieben ist, dass die Gegenwalze auf einer Lager- und Verstellachse frei drehbar gelagert ist, dass die Lager- und Verstellachse um ihre Längsachse verstellbar ist, dass die Lager- und Verstellachse Achsstücke aufweist, die außermittig/exzentrisch zur Drehachse der Lager- und Verstellachse angeordnet sind und dass Mitnehmerringe frei drehbar auf den Achsstücken angeordnet und durch Reibschluss zugleich mit der Schneidwalze über deren Schmitzringe angetrieben sind.to solution This object is achieved by the invention with the features of the characterizing Teiles of claim 1, that the cutting roller on their Bearing pin is directly driven, that the counter roll up a warehouse and Adjusting axis is freely rotatably mounted, that the bearing and adjustment axis around its longitudinal axis it is adjustable that the bearing and adjustment axle has axle pieces, the off-center / eccentric are arranged to the axis of rotation of the bearing and adjustment axis and that driving rings freely rotatable on the axle pieces arranged and by frictional engagement at the same time with the cutting roller on the Schmitzringe are driven.
Mit den besagten Merkmalen wird eine Einstellung des Schneidspaltes sowohl in positiver als auch in negativer Richtung auch während des Betriebes mühelos ermöglicht, ohne dass die wirksame Schneidenebene und die wirksame Schnittkraft verändert werden und die Gegenwalze ihre Lage verändert. Ferner ist eine Nachstellung des Schneidspaltes aufgrund von Werkzeugverschleiß möglich. Gleichermaßen wird die Einstellbarkeit hinsichtlich der Dicke von Trägerfolien und Papieren beim Anstanzen zum Beispiel von Etiketten erreicht. Die Einstellbarkeit ist mit einer Auflösung von 1 μm und kleiner möglich.With said features is an adjustment of the cutting gap both in the positive and in the negative direction during the Operation effortlessly allows without the effective cutting plane and effective cutting force changed and the counter roll changes its position. There is also an adjustment the cutting gap due to tool wear possible. Equally will the adjustability in terms of the thickness of carrier films and papers when punching, for example, from labels. The adjustability is possible with a resolution of 1 μm and smaller.
Des weiteren können mit der Vorrichtung zwei verschiedene Schneidsysteme verwirklicht werden, ein aktives Schneidsystem, mit angetriebener Gegenwalze und ein passives Schneidsystem, mit fixierter Gegenwalze.Furthermore, with the device, two different cutting systems can be realized, an active cutting system with driven counter-roll and a passive cutting system with fi x counter-roller.
Wobei das aktive Schneidsystem besonders für Materialien, wie z. B. Tissuepapier, mit einer hohen Bruchdehnung und das passive Schneidsystem für Materialien, wie z. B. Briefumschlagpapier, mit geringer Bruchdehnung eingesetzt werden.In which the active cutting system especially for materials such. Tissue paper, with a high elongation at break and the passive cutting system for materials, such as As envelope paper, used with low elongation at break become.
Erreicht wurden diese Vorteile im Wesentlichen dadurch, dass exzentrische Achsstücke auf der Lager- und Verstellachse angeordnet sind und dass auf diesen versetzten Achsstücken jeweils Mitnehmerringe exzentrisch umlaufen.Reached These benefits were essentially due to being eccentric spindle components are arranged on the bearing and adjustment axis and that on this staggered axle pieces each eccentric drive rings.
Auch Prägeanwendungen und das Laminieren von Bahnen, wenn genaue Laminierschichtdicken erforderlich sind, lassen sich mit der beschriebenen Verstelleinrichtung erzielen. Es versteht sich, dass in einem solchen Fall natürlich keine Schneidwalze vorgesehen ist, sondern eine zweite Druckwalze bzw. Prägewalze.Also embossing applications and laminating webs when exact lamination thicknesses are required, can be with the described adjustment achieve. It is understood that in such a case, of course, no Cutting roller is provided, but a second pressure roller or Embossing roll.
