Description
Diese Erfindung bezieht sich auf eine verbesserte Vorrichtung zum Schneiden von laminaren Materialien.This invention relates to an improved apparatus for cutting laminar materials.
Im Besonderen bezieht sich diese Erfindung auf eine Vorrichtung zum Scher- oder Quetschschneiden in Längsrichtung, bei welcher der Flansch, der das Kreismesser der mehreren Einheiten trägt, mit Mitteln versehen ist, die geeignet sind, während der Schneidvorgänge des Materials das Auftreten von Schwingungen zu verhindern, die erhebliche Mängel hinsichtlich der Schnittqualität verursachen können.More particularly, this invention relates to a device for shear or crush cutting in the longitudinal direction, in which the flange carrying the circular knife of the plurality of units is provided with means suitable for preventing the occurrence of vibrations during the cutting operations of the material which can cause significant shortcomings in terms of the quality of the cut.
Zum Längsschneiden in Streifen von bandförmigen Materialien wie Papier, Pappe, Folien unterschiedlicher Art, Stoffen und technischen Materialien, Glasfasern, Karbon und Ähnlichem, gegebenenfalls übereinander gelegt, so dass zwei oder mehr untereinander verbundene Lagen gebildet werden, werden bekanntermaßen spezielle Einrichtungen verwendet, die mit mehreren Einheiten versehen sind, die auf einer Tragschiene aneinandergereiht sind und voneinander in Abhängigkeit von der Breite der Streifen, die aus dem von einer Spule abgewickelten Material erhalten werden soll, beabstandbar sind. Jede der Einheiten umfasst ein Messer, das durch Reibung oder Zug durch den Kontakt mit dem darunter liegenden angetriebenen Gegenmesser in Drehung versetzt wird; pneumatische oder angetriebene Mittel ermöglichen das Bewegen und Einstellen der Positionierung zwischen Messer und Gegenmesser in Abhängigkeit von Dicke und Art des zu schneidenden Materials. Die einzelnen Schneideinheiten umfassen einen Tragkopf und einen Flansch; Letzterer trägt die Messer und ist üblicherweise mit einem Kugellager gekoppelt, das die Drehbewegung des Messers erleichtert. Aufgrund der im Allgemeinen geringen Breite der Messerhalter ist es möglich, ein einziges Lager für die Montage des Messerhalterflansches zu verwenden; auch das Lager weist infolgedessen eine begrenzte Größe auf, so dass es nicht spielarm ist und eine Schwingung zwischen dem Innen- und dem Außenring dieses Lagers beinhaltet. Daraus folgt, dass es im Laufe der Zeit zu einer Schwingung des Messers kommt, mit möglichen Problemen bei der Schnittqualität und der einwandfreien Funktionsweise des Messer- oder Klingenhalters.For lengthwise cutting into strips of tape-like materials such as paper, cardboard, foils of different types, fabrics and technical materials, glass fibers, carbon and the like, optionally placed one on top of the other, so that two or more interconnected layers are formed, special devices are known to be used, which with a plurality of units are provided which are lined up on a support rail and can be spaced apart from one another as a function of the width of the strips that are to be obtained from the material unwound from a reel. Each of the units comprises a knife which is rotated by friction or traction through contact with the driven counter knife below; Pneumatic or powered means allow moving and adjusting the positioning between knife and counter knife depending on the thickness and type of material to be cut. The individual cutting units comprise a support head and a flange; The latter carries the knife and is usually coupled to a ball bearing that facilitates the rotary movement of the knife. Due to the generally small width of the knife holder, it is possible to use a single bearing for mounting the knife holder flange; As a result, the bearing also has a limited size, so that it does not have a low clearance and contains an oscillation between the inner and outer ring of this bearing. As a result, the knife will vibrate over time, with possible problems with the quality of the cut and the proper functioning of the knife or blade holder.
Ein weiterer Nachteil, der durch die Verwendung des Kugellagers von begrenzter Größe bedingt ist, betrifft die Unmöglichkeit, den Schneidwinkel des Messers in Bezug auf das Gegenmesser aufgrund des Spiels und der Bewegung des Messers konstant zu halten; auch in diesem Fall geht dies zulasten der Schnittqualität.Another disadvantage caused by the use of the ball bearing of limited size relates to the impossibility of keeping the cutting angle of the knife constant with respect to the counter knife due to the play and the movement of the knife; in this case too, this is at the expense of the quality of the cut.
Aufgabe dieser Erfindung ist es, die oben angeführten Nachteile zu überwinden.The object of this invention is to overcome the disadvantages mentioned above.
Im Besonderen besteht die Aufgabe dieser Erfindung darin, eine verbesserte Vorrichtung zum Schneiden von laminaren Materialien bereitzustellen, bei der das Messer auch nach einer Langzeitverwendung schwingungsfrei ist.In particular, the object of this invention is to provide an improved apparatus for cutting laminar materials in which the knife is vibration-free even after long-term use.
Eine weitere und daraus folgende Aufgabe der Erfindung besteht darin, eine Vorrichtung wie oben definiert bereitzustellen, die in der Lage ist, den Schneidwinkel des Messers in Bezug auf das Gegenmesser konstant zu halten und auf diese Weise eine hohe Schnittqualität sowie die einwandfreie Funktionsweise des Messerhalters zu gewährleisten.A further and consequent object of the invention is to provide a device as defined above which is able to keep the cutting angle of the knife constant in relation to the counter knife and in this way to ensure a high quality of cut and the proper functioning of the knife holder guarantee.
Eine weitere Aufgabe der Erfindung besteht darin, den Verwendern eine verbesserte Schneidvorrichtung zur Verfügung zu stellen, die in der Lage ist, eine lange Standzeit und Zuverlässigkeit zu gewährleisten, und darüber hinaus einfach und wirtschaftlich herstellbar ist.Another object of the invention is to provide users with an improved cutting device which is able to ensure a long service life and reliability and, moreover, can be produced simply and economically.
Diese und weitere Aufgaben werden mit der verbesserten Schneidvorrichtung dieser Erfindung gemäß dem Hauptanspruch gelöst.These and other objects are achieved with the improved cutting device of this invention according to the main claim.
