The spacings between these cutters provide a wide selection of strip width from which to select the one most appropriate for the strip required to be cut.

Description

Die Erfindung betrifft eine Untermesserwelle für eine Rollenschneidmaschine zum Längsschneiden von Folien und Bändern in Streifen mit mindestens einem Untermesser sowie eine Rollenschneidmaschine zum Längsschneiden von Folien und Bändern in Streifen.The invention relates to a lower knife shaft for a Roll cutting machine for slitting foils and Bands in strips with at least one lower knife as well as a slitter for slitting Foils and tapes in strips.

Rollenschneidmaschinen werden insbesondere zum Schneiden von Aluminiumfolien und -bändern aber auch zum Schneiden von Verbundwerkstoffen aus Aluminium und Papier sowie aus Aluminium und Kunststoff und zum Schneiden von anderen Folien, Bändern und Verbundwerkstoffen in einem Dickenbereich von einigen µm bis zu etwa einem mm eingesetzt. Die zu schneidenden Folien oder Bänder können sowohl blank als auch lackiert sein. Die zu schneidenden Verbundwerkstoffe werden beispielsweise durch Kaschieren oder Extrudieren hergestellt.Roll slitting machines are used especially for cutting of aluminum foils and strips, but also for cutting of composite materials made of aluminum and paper as well as Aluminum and plastic and for cutting others Films, tapes and composite materials in one Thickness range from a few µm up to about one mm used. The foils or tapes to be cut can be both bare and painted. The ones to be cut Composites are made, for example, by lamination or extruded.

Im weiteren wird die erfindungsgemäße Untermesserwelle bzw. die erfindungsgemäße Rollenschneidmaschine am Beispiel des Schneidens von Aluminiumfolien oder -Bändern erläutert. Unter Aluminium bzw. Aluminiumwerkstoffen werden dabei Legierungen verstanden, die etwa mindestens 90% Aluminium enthalten.Furthermore, the lower knife shaft according to the invention or the roll cutting machine according to the invention on Example of cutting aluminum foils or strips explained. Under aluminum or aluminum materials are understood as alloys that are at least about Contain 90% aluminum.

Zur Herstellung von Aluminiumfolien und -bändern werden in einer ersten Stufe Barren in Breiten zwischen 900 und 2200 mm gegossen und zunächst warm und abschließend kalt auf Enddicke gewalzt. Je nach Einsatzzweck in der anschließenden Verarbeitung stellt die Aluminium-Halbzeugindustrie die Aluminiumfolien und -bänder in unterschiedlichen Enddicken und -breiten her. Dabei wird die Enddicke durch die Stichabnahmen im Walzprozeß bestimmt. Die Endbreite wird durch Längsteilen der Bänder oder Folien auf sogenannten Rollenschneidmaschinen einoder mehrlagig hergestellt.For the production of aluminum foils and tapes in a first stage bars in widths between 900 and 2200 mm cast and first warm and then cold rolled to final thickness. Depending on the application in the Subsequent processing is provided by the semi-finished aluminum industry the aluminum foils and tapes in different final thicknesses and widths. Doing so the final thickness through the stitch decreases in the rolling process certainly. The final width is obtained by dividing the bands lengthways or films on so-called roll cutting machines manufactured in multiple layers.

Eine Rollenschneidmaschine besteht grundsätzlich aus drei Baugruppen,

  • 1. einem Abwickler, auf dem das sogenannte Mutterband abgewickelt wird,
  • 2. einer Schneidpartie, in der das Band durch Messer der Länge nach in schmalere Streifen geschnitten wird und
  • 3. einer Aufwicklung, in der die zuvor geschnittenen Streifen zu Rollen aufgewickelt werden.
    • A slitter rewinder basically consists of three assemblies,
  • 1. an unwinder on which the so-called mother tape is wound,
  • 2. a cutting section in which the tape is cut lengthwise into narrower strips and
  • 3. a winder in which the previously cut strips are wound into rolls.

    • Die vorliegende Erfindung bezieht sich insbesondere auch auf das sogenannte Scherenschnitt-Verfahren. Hierbei wird das Band oder die Folie über eine Untermesserwelle mit einer gewissen Umschlingung geführt. Ein in die Untermesserwelle eintauchendes Obermesser, welches beispielsweise entweder als Rasierklinge oder als Rundmesser ausgebildet ist, schneidet das Aluminium in einem Punkt in der Art eines Scheren- bzw. Messerschnitts. Das Obermesser wird herkömmlicherweise durch eine Feder an das Untermesser angedrückt. Neuere Verfahren nutzen hierzu statt einer Feder Pneumatikzylinder oder Membranzylinder.The present invention also relates in particular to the so-called paper cutting process. Here will the tape or the film with a lower knife shaft a certain wrap. One in the Lower knife shaft immersing upper knife, which for example either as a razor blade or as Is formed, the aluminum cuts in a point like a scissor or Knife cut. The upper knife becomes conventional pressed against the lower knife by a spring. newer Methods use instead of a spring Pneumatic cylinder or membrane cylinder.

    Beim Längsschneiden von Folien oder Bänder müssen regelmäßig die Schnittbreiten für die zu schneidenden Bänder angepaßt werden. Hierzu müssen zunächst die Obermesser auf die neuen Schnittbreiten eingestellt werden, was mit vergleichsweise geringem Aufwand in kurzer Zeit möglich ist. Neben der Anpassung der Obermesser an die Schnittbreiten muß auch die Untermesserwelle an die neuen Schnittbreiten angepaßt werden. Hierzu muß bei den bekannten Rollenschneidmaschinen die gesamte Untermesserwelle gewechselt werden, um eine Untermesserwelle einzubauen, auf der die Untermesser an den, zu der neuen Schnittbreite korrespondierenden axialen Position auf der Untermesserwelle angeordnet sind. Hierzu werden auf der Untermesserwelle Paßstücke zwischen den Untermessern angeordnet, um die erforderlichen Abstände herzustellen. Dies verursacht einen beträchtlichen Aufwand an Rüstzeiten und damit hohe Kosten.When slitting foils or tapes regularly the cutting widths for the ones to be cut Bands can be adjusted. To do this, the Upper knife adjusted to the new cutting widths become what with comparatively little effort short time is possible. In addition to adjusting the The upper knife to the cutting widths must also Lower knife shaft adapted to the new cutting widths become. For this, the known Roll cutting machines the entire lower knife shaft be changed to install a lower knife shaft, on which the lower knife to the to the new one Cutting width corresponding axial position on the Lower knife shaft are arranged. For this purpose, the Lower knife shaft adapters between the lower knives arranged to make the required distances. This causes considerable effort Setup times and thus high costs.

    Ausgehend von dem zuvor beschriebenen Stand der Technik und den hiermit verbundenen Problemen liegt der vorliegenden Erfindung die Aufgabe zu Grunde, eine Untermesserwelle bzw. eine Rollenschneidmaschine zur Verfügung zu stellen, mit der die Rüstzeiten zur Herstellung geänderter Schnittbreiten wesentlich verringert sind.Starting from the prior art described above and the problems associated with it lies present invention the object of a Lower knife shaft or a slitter rewinder To make available with which the setup times for Manufacture of modified cutting widths essential are reduced.

    Die zuvor hergeleitete und aufgezeigte Aufgabe wird für eine Untermessewelle für eine Rollenschneidmaschine zum Längsschneiden von Folien und Bändern in Streifen mit mindestens einem Untermesser dadurch gelöst, daß die Untermesserwelle eine über die Schnittanzahl hinausgehende Anzahl von Untermessern aufweist, die Untermesser in im wesentlichen regelmäßigen Abständen auf der Untermesserwelle angeordnet sind und die Abstände zwischen den Untermessern eine flexible Wahl der Breite der Streifen zulassend gewählt sind. Dadurch, daß auf der Untermesserwelle Untermesser derart angeordnet sind, daß sie eine flexible Wahl der Breite der zuzuschneidenden Streifen zulassen, ist gewährleistet, daß eine Umstellung der Rollenschneidmaschine auf geänderte Schnittbreiten ohne Ausfallzeiten für Umbauten an der Untermesserwelle vorgenommen werden können. Es müssen lediglich die wesentlich einfacher zu handhabenden Obermesser relativ zu den, der geänderten Schnittbreite zuzuordnenden Untermessern geeignet positioniert werden, um die nächste Schneidpartie mit den gewünschten geänderten Schnittbreiten herzustellen. Durch die erheblich reduzierten Rüstzeiten ergibt sich eine wesentlich höhere Ausnutzung der Maschinenlaufzeit, was wiederum zu deutlich reduzierten Kosten für den Schneidvorgang führt.The previously derived and shown task is for a lower diameter shaft for a slitter winder Slitting foils and tapes into strips solved at least one lower knife in that the Lower knife shaft one over the number of cuts has an additional number of lower knives that Bottom knife at substantially regular intervals the lower knife shaft are arranged and the distances a flexible choice of width between the lower knives the stripes are selected to allow. The fact that on the Lower knife shaft are arranged in such a way that they have a flexible choice of width to be cut Allowing stripes ensures that a switch the slitter rewinder to changed cutting widths without downtime for conversions on the lower knife shaft can be made. It just has to much easier to handle upper knife relatively to those assigned to the changed cutting width Lower knives can be positioned appropriately to the next one Cutting section with the desired changed To produce cutting widths. By the considerably Reduced set-up times result in a much higher one Utilization of the machine runtime, which in turn increases significantly reduced costs for the cutting process.

    Der Abstand zwischen den auf einer erfindungsgemäßen Untermesserwelle angeordneten Untermesser läßt sich dadurch reduzieren, daß die Untermesser abwechselnd als Untermesser für linken und rechten Schnitt ausgebildet sind. Ein reduzierter Abstand der Untermesser gewährleistet eine flexiblere Anpassung an gewünschte Schnittbreiten.The distance between those on an inventive Lower knife shaft arranged lower knife can be reduce in that the lower knife alternately as Lower knife designed for left and right cuts are. A reduced distance between the lower knives ensures a more flexible adaptation to the desired Cutting widths.

    Die abwechselnde Anordnung von Untermessern für linken und rechten Schnitt läßt sich besonders geeignet dadurch herstellen, daß die Untermesser als beidseitige Schneidkanten an den Federn einer Nut-Feder-Teilung der Untermesserwelle ausgebildet sind.The alternating arrangement of lower knives for left and right cut can be particularly suitable make the bottom knife as double-sided Cutting edges on the tongues of a tongue and groove division of the Lower knife shaft are formed.

    Dadurch, daß gemäß einer weiteren Ausgestaltung der erfindungsgemäßen Untermesserwelle die Untermesserwelle eine Mehrzahl von Schneidbüchsen aufweist und die Schneidbüchsen jeweils eine Mehrzahl von Untermessern aufweisen, ist gewährleistet, daß bei einem Verschleiß der Untermesser in bestimmten Bereichen der Untermesserwelle nicht die gesamte Untermesserwelle ausgetauscht werden muß. Bei einer derart ausgestalteten Untermesserwelle können die Schneidbüchsen, die einen besonders hohen Verschleiß aufweisen ausgetauscht werden, während die keinen oder einen geringeren Verschleiß aufweisenden Schneidbüchsen weiter verwendet werden können.The fact that according to a further embodiment of the lower knife shaft according to the invention the lower knife shaft has a plurality of cutting sleeves and the Cutting sleeves each have a plurality of lower knives have, it is ensured that in the event of wear the lower knife in certain areas of the Lower knife shaft not the entire lower knife shaft needs to be replaced. With such a design Lower knife shaft can the cutting sleeves, the one exhibit particularly high wear, while the no or less wear having cutting sleeves continue to be used can.

    Um eine möglichst flexible Einstellung der Schnittbreiten zu gewährleisten ist es sinnvoll, daß die Untermesser in einem Abstand von etwa 0,5 bis 10 mm zueinander angeordnet sind. Besonders vorteilhaft ist die Anordnung (Teilung) der Schneidkanten in einem Abstand von etwa 0,8 bis 2 mm zueinander.To make the cutting widths as flexible as possible to ensure it makes sense that the lower knife in a distance of about 0.5 to 10 mm to each other are arranged. The arrangement is particularly advantageous (Division) of the cutting edges at a distance of about 0.8 up to 2 mm to each other.

    Insbesondere beim Schneiden von Aluminiumfolien ist es im Hinblick auf das mögliche Abdrücken des Untermesserwellenprofils auf die zu schneidende Aluminiumfolie sinnvoll, die Nutbreiten möglichst gering zu halten. Dabei hat sich eine Nutbreite im Bereich von 0,8 bis 2 mm als besonders geeignet im Hinblick auf ein geringes Abdrücken und im Hinblick auf das zur Verfügung stellen von genügend Raum zum Eintauchen eines Obermessers bewährt. Especially when cutting aluminum foils it is in the With regard to the possible impression of the Lower cutter shaft profile on the one to be cut Aluminum foil makes sense, the groove widths as small as possible to keep. There is a groove width in the range of 0.8 to 2 mm as particularly suitable with regard to a small footprints and in view of that available provide enough room to immerse one Tried and tested.

    Schließlich wird die oben hergeleitete und aufgezeigte Aufgabe durch eine Rollenschneidmaschine zum Längsteilen von Folien und Bändern in Streifen mit einer erfindungsgemäßen Untermesserwelle und mindestens zwei in die Untermesserwelle eintauchenden Obermessern gelöst.Finally, the one derived and shown above Job by a slitter for slitting of foils and tapes in strips with a lower knife shaft according to the invention and at least two in the lower knives immersing the upper knives.
