Description

Die Erfindung betrifft eine Stützeinrichtung für eine Materialbahn, insbesondere Papierbahn, für eine Schneidvorrichtung der Materialbahn, insbesondere an einer Längsschneidvorrichtung einer Maschine der papierverarbeitenden Industrie. Ferner betrifft die Erfindung eine Verwendung einer Stützeinrichtung sowie einer Anordnung zum Schneiden einer Materialbahn, insbesondere Papierbahn, und eine Maschine der papierverarbeitenden Industrie.The invention relates to a support device for a Material web, in particular paper web, for a cutting device the material web, especially on one Longitudinal cutting device of a machine for paper processing Industry. The invention further relates to a use of a support device and one Arrangement for cutting a material web, in particular Paper web, and a machine of paper processing Industry.

Unter der Bezeichnung SLK ist ein Formatschneider der Anmelderin bekannt. Vor dem Längsschneider werden mehrere Papierbahnen zusammengeführt und in der Längsschneidvorrichtung dann in Streifen mit einer vorgegebenen Breite, beispielsweise von 210 mm für DIN A 4 geschnitten. Die Längsschneidvorrichtung ist eine stationäre Längsschneideeinheit mit Tangentialschnitt. A format cutter is the SLK Applicant known. Before the slitter several paper webs brought together and in the slitter then in strips with a given Width, for example of 210 mm for A4 cut. The slitter is one stationary slitting unit with tangential cut.

Die Längsschnittstation in dieser Papierverarbeitungsmaschine besteht aus einem Ober- und einem Untermesser, durch die hindurch mindestens eine Papierbahn geführt und in Papierstreifen geschnitten wird. Vorrichtungen zum Längsschneiden laufender Papierbahnen sind in der Patentschrift DE 28 21 956 C2 und in der Offenlegungsschrift DE 39 06 376 A1 beschrieben.The longitudinal cutting station in this paper processing machine consists of an upper and a lower knife, through which at least one paper web is guided and cut into strips of paper. devices for slitting running paper webs are in the Patent specification DE 28 21 956 C2 and in the published patent application DE 39 06 376 A1 described.

Zum Schneiden einer Papierbahn werden mehrere Längsschneider parallel und nebeneinander eingesetzt, die in einem formatbestimmenden Abstand angeordnet werden können. Bei den formatflexiblen Längsschneidern kann das Papier zwischen einzelnen Längsschneidermesserhaltern nicht unterstützt werden, da diese quer zur Papierbahnlaufrichtung formatabhängig verschoben werden. Das Papier wird mit einer sehr geringen Umschlingung über die Untermesser gespannt. Vor und hinter den Längsschneidern sind Umlenkwalzen angeordnet. Diese Walzen sind weit vom Schnittpunkt des Papiers entfernt, da sie üblicherweise einen großen Durchmesser von bis zu 150 mm aufweisen, um eine ausreichende Stabilität über die gesamte Arbeitsbreite der Längsschneidvorrichtung zu gewährleisten.Several slitters are used to cut a paper web used in parallel and side by side, which in a format-determining distance can. This can be done with the format-flexible slitters Paper between individual slitter knife holders are not supported, since these are transverse to the direction of the paper web depending on the format. The Paper is wrapped with very little wrap the lower knives cocked. In front and behind the slitter deflection rollers are arranged. These rollers are far from the intersection of the paper as they usually a large diameter of up to 150 mm have sufficient stability over the total working width of the slitter guarantee.

Das stramm gehaltene Papier neigt jedoch dazu, an den Stellen, an denen es nicht von den Untermessern gestützt wird, zwischen den Walzen und /oder den Längsschneidern durchzusacken. Diese Durchwölbung ist um so größer, je weiter die Walzen von den Längsschneidern entfernt und je weiter die Längsschneider jeweils auseinander sind. Darüber hinaus begünstigt ein großer Walzenabstand die Bildung von Längsfalten in den zu schneidenden Papierbahnen. However, the taut paper tends to stick to the Places where it is not supported by the lower knives between the rollers and / or the slitters sag. This arch is the greater, ever further removed the rollers from the slitter and the further apart the longitudinal cutters are. In addition, a large roller gap favors the Formation of longitudinal folds in the paper webs to be cut.

Die Aufgabe der vorliegenden Erfindung besteht darin, die Unterstützung der geförderten Papierbahnen an der Längsschneidvorrichtung und die Schnitthaltigkeit bei den Längsschneidern zu verbessern.The object of the present invention is the support of the funded paper webs at the Longitudinal cutting device and edge retention to improve the slitter.

Eine erste Lösung der Aufgabe besteht bei der Stützeinrichtung gem. der eingangs genannten Art darin, daß die Stützeinrichtung mittels wenigstens einer Stützwelle und wenigstens einem Lagermittel zur drehbaren Lagerung der Stützwelle außerhalb der Rotationsachse der Stützwelle ausgebildet ist. Durch die erfindungsgemäße Stützeinrichtung wird erreicht, daß die Unterstützung der Papierbahn dicht vor/oder hinter dem Schnittpunkt der, insbesondere stationären, Schneidvorrichtung entsteht. Die erfindungsgemäße Lagerung der Stützwelle gestattet es, dünne Wellen zu verwenden, da eine Durchbiegung der Welle in Folge des erfindungsgemäßen Lagermittels verhindert wird. Durch die Verkürzung des Abstands zwischen der Stützwelle und dem Schnittpunkt kann die Stützeinrichtung im Einlaufbereich und/oder Auslaufbereich der Schneideinrichtung angeordnet werden, so daß die transversale Biegung der Materialbahn zwischen den Schneidvorrichtungen verringert oder gar verhindert wird. Außerdem erfolgt durch die Anordnung der Stützeinrichtung im Einlaufbereich und/oder im Auslaufbereich für eine geringerere Umschlingung der Materialbahn auf dem Untermesser. Darüber hinaus wird hierdurch die Bildung von Längsfalten in den Papierbahnen verringert.The support device provides a first solution to the problem gem. of the type mentioned in that the Support device by means of at least one support shaft and at least one bearing means for rotatably supporting the Support shaft outside the axis of rotation of the support shaft is trained. Through the support device according to the invention is achieved that the support of the Paper web just before / or behind the intersection of the especially stationary, cutting device arises. The support shaft support according to the invention allows it to use thin waves because of a deflection of the Wave as a result of the bearing means according to the invention is prevented. By shortening the distance between the support shaft and the intersection Support device in the inlet area and / or outlet area the cutter can be arranged so that the transverse bend of the material web between the Cutting devices reduced or even prevented becomes. In addition, the arrangement of the support means in the inlet area and / or in the outlet area for a lower wrap around the material web the lower knife. In addition, the Formation of longitudinal folds in the paper webs reduced.

Da die Lagerung der Stützwelle nicht mehr kollinear mit der Rotationsachse der Welle ist, ist es vorteilhaft, wenn das Lagermittel als wenigstens eine, vorzugsweise entlang der Stützwelle angeordnete, Lagereinrichtung ausgebildet ist. Because the support shaft is no longer collinear with the axis of rotation of the shaft, it is advantageous if the storage means as at least one, preferably bearing device arranged along the support shaft is trained.

Hierdurch wird die Stützwelle an bestimmten Punkten, z.B. zwischen den Untermessern gezielt unterstützt. Ferner reduziert sich hierdurch das Gewicht der Stützeinrichtung, da nur abschnittsweise die Lagereinrichtung oder die Lagerelemente ausgebildet sind. Durch die Abstützung an mehreren Punkten der Stützwelle wird gezielt verhindert, daß sich die Welle durchbiegt.In addition, the storage facility is advantageous and / or the bearing elements axially parallel to the support shaft, preferably in the longitudinal direction of the support shaft in predetermined distances. This will make the Support shaft at certain points, e.g. between Targeted support of lower knives. It also reduces thereby the weight of the support device, since only sections of the storage facility or the storage elements are trained. By supporting several Points of the support shaft are specifically prevented the wave deflects.

Damit die Stützwelle nicht aus der Lagerung springen kann, ist wenigstens eine Halteeinrichtung für die Stützwelle vorgesehen. So that the support shaft does not jump out of storage can, is at least one holding device for the Support shaft provided.

Insbesondere ist vorteilhaft, wenn die Halteeinrichtung berührungslos die Stützwelle hält. Dies stellt eine Vereinfachung in der Konstruktion dar.It is particularly advantageous if the holding device holds the support shaft without contact. This represents one Simplification in construction.

Darüber hinaus ist vorteilhafterweise die Halteeinrichtung mittels wenigstens eines Magneten ausgebildet. Durch die magnetischen Kräfte wird die Stützwelle in der Lagereinrichtung bzw. in den Lagerelementen drehbar gehalten.In addition, the holding device is advantageous formed by means of at least one magnet.

Des weiteren ist erfindungsgemäß vorgesehen, daß Halteeinrichtungen und/oder die Magnete in vorbestimmten Abständen entlang der Stützwelle angeordnet sind.Furthermore, it is provided according to the invention that holding devices and / or the magnets in predetermined Distances are arranged along the support shaft.

Gemäß einer vorteilhaften Ausführungsform der Erfindung ist zwischen zwei Lagereinrichtungen wenigstens eine Halteeinrichtung oder zwischen zwei Halteeinrichtungen wenigstens eine Lagereinrichtung angeordnet. Dadurch läßt sich eine alternierende Folge von Lagereinrichtung und Halteeinrichtung ausbilden, so daß eine zuverlässige Unterstützung der Stützwelle sowie eine sichere Halterung der Stützwelle erreicht wird.According to an advantageous embodiment of the invention is at least one between two storage facilities Holding device or between two holding devices arranged at least one storage device. Thereby can be an alternating sequence of storage facilities and form the holding device so that a reliable Support of the support shaft as well as a secure bracket the support shaft is reached.

Darüber hinaus ist es insbesondere von Vorteil, wenn wenigstens eine Trageeinrichtung für die Lagereinrichtung und/oder die Halteeinrichtung vorgesehen ist, so daß die Lagereinrichtung und/oder die Halteeinrichtung zusammen mit der Stützwelle kompakt angeordnet werden kann. Darüber hinaus gestattet die Trageeinrichtung eine gute Positionierung der Stützeinrichtung im Einlauf- und im Auslaufbereich der Längsschneider. Ferner ist durch die Trageinrichtung eine kompakte Ausbildung möglich, so daß die Stützeinrichtung leicht ausgetauscht werden kann. In addition, it is particularly advantageous if at least one carrying device for the storage device and / or the holding device is provided, so that the storage device and / or the holding device be arranged compactly together with the support shaft can. In addition, the carrying device allows one good positioning of the support device in the inlet and in the outlet area of the slitter.

In den folgenden Figuren sind gleiche Elemente mit denselben Bezugsziffern versehen, so daß von einer erneuten Vorstellung jeweils abgesehen wird.The same figures are used in the following figures provided with the same reference numbers, so that from a will not be presented again.

In Fig. 1 ist eine Schneideanordnung zum Schneiden einer Papierbahn 5 in einer Längsschneidestation einer Papierverarbeitungsmaschine gezeigt. Die Längsschneidestation besteht aus einer Längsschneidvorrichtung 2 mit einem Obermesser 3 und einem Untermesser 4, die im Tangentialschnitt eine zwischen dem Untermesser und dem Obermesser hindurchgeführte Papierbahn schneiden.In Fig. 1 is a cutting arrangement for cutting a Paper web 5 in a longitudinal cutting station of a paper processing machine shown. The slitting station consists of a slitter 2 with an upper knife 3 and a lower knife 4, which in Tangential cut one between the lower knife and the Cut the paper web passed through the upper knife.

Vor der Längsschneidvorrichtung 2 und hinter der Längsschneidvorrichtung 2 ist jeweils eine Unterstützungswelle 6 angeordnet, um die Papierbahn 5 in transversaler Richtung, d.h. in einer zur Zeichenebene senkrechten Ebene, zu stützen. Aufgrund der Breite der Papierbahn 5 ist es erforderlich, daß die Unterstützungswellen 6 eine ausreichende Stabilität über die gesamte Papierbahnbreite aufweisen. Hierzu sind die Unterstützungswellen 6 mit einem entsprechend großen Durchmessers bis zu 150 mm ausgebildet. Aufgrund dieses großen Durchmesser der Unterstützungswelle 6 können diese Unterstützungswellen 6 allerdings nur in einer entsprechend weiten Entfernung vom Schnittpunkt der Papierbahn 5 angeordnet werden.In front of the slitter 2 and behind the slitter 2 is a wave of support 6 arranged to the paper web 5 in transverse Direction, i.e. in a perpendicular to the plane of the drawing Level to support. Due to the width of the paper web 5 it is necessary that the support waves 6 a sufficient stability over the entire width of the paper web exhibit. For this purpose, the support waves 6 with a correspondingly large diameter up to 150 mm educated. Because of this large diameter the Support wave 6 can support waves 6, however, only at a correspondingly long distance be arranged from the intersection of the paper web 5.

Um ein genaues Schneiden zu gewährleisten, ist es erforderlich, daß die Papierbahn 5 mit einer sehr geringen Umschlingung über das Untermesser 4 und die anderen parallel dazu angeordneten Untermessern gespannt wird. Das in der Längsschneidestation 2 eingespannte Papier 5 wird zwischen zwei Untermessern im Bereich der Schnittebenen nicht unterstützt, so daß die Papierbahn 5 eine direkte Verbindung zwischen den Unterstützungswellen 6 einnimmt, wodurch die Papierbahn zwischen den Untermessern 4 und den Unterstützungswellen 6 durchsackt (gestrichelte Linie 7). Die Höhe der Durchwölbung ist abhängig vom Abstand der nebeneinander angeordneten Untermesser und vom Abstand zwischen den Unterstützungswellen im Einlauf- und im Auslaufbereich der Längsschneidvorrichtung 2. Durch einen großen Abstand der Unterstützungswellen 6 voneinander wird die Bildung von Längsfalten in der Papierbahn 5 begünstigt. Dies führt bei formatflexiblen Längsschneidern zu Problemen bei der Schnitthaltigkeit.To ensure accurate cutting, it is required that the paper web 5 with a very low wrap over the lower knife 4 and the other lower knives arranged in parallel becomes. The clamped in the slitting station 2 Paper 5 is between two lower knives in the area of Cutting planes are not supported, so that the paper web 5 a direct link between the support waves 6 occupies, whereby the paper web between the Lower knives 4 and the support shafts 6 sagged (dashed line 7). The amount of bulge is depending on the distance between the side by side Lower knife and the distance between the support shafts in the inlet and outlet area of the Longitudinal cutting device 2. By a large distance the support waves 6 from each other will form favored by longitudinal folds in the paper web 5. This leads to problems with format-flexible slitters in the edge retention.

Um die Schnitthaltigkeit bei der Längsschneidvorrichtung 2 zu verbessern, ist erfindungsgemäß vorgesehen, die Papierbahn 5 so dicht wie möglich vor und hinter dem Schnittpunkt zu unterstützen. Hierdurch wird die Durchwölbung der Papierbahn 5 zwischen den parallel angeordneten Untermessern gegenüber dem Stand der Technik deutlich verringert. Bei einigen Papieren ist es sogar möglich, die Durchwölbung der Papierbahn vollständig zu verhindern.The edge retention of the slitter 2, the invention provides that Paper web 5 as close as possible in front of and behind the Support intersection. This causes the arching the paper web 5 between the arranged in parallel Lower knives compared to the prior art significantly reduced. With some papers it is possible to completely arch the paper web prevent.

In Fig. 2 ist eine Längsschneidvorrichtung 2 im Querschnitt gezeigt, bei der im Einlaufbereich und im Auslaufbereich der Papierbahn 5 jeweils eine erfindungsgemäße Stützungseinrichtung 10 für die Materialbahn 5 angeordnet ist. Die Unterstützungseinrichtung 10 ist im Prinzipaufbau schematisch dargestellt. Die Stützeinrichtung 10 weist jeweils eine Stützwelle 11 auf, die dieselbe Funktion hat wie die Unterstützungswelle 6 (Fig. 1). Die Stützwelle 11 ist mittels mehrerer, entlang der Stützwelle 11 angeordneten Kugellager 12 drehbar gelagert. Um die Stützwelle 11 drehbar in der Stützeinrichtung 10 zu halten, ist an der Unterseite der Stützeinrichtung 10 ein Magnet 13 angeordnet, der aufgrund der magnetischen Kräfte die Stützwelle 11 in der Stützeinrichtung 10 hält.2 is a longitudinal cutting device 2 in cross section shown in the infeed area and Outfeed area of the paper web 5 each has an inventive Support device 10 for the material web 5 is arranged. The support device 10 is in the Principle structure shown schematically. The support device 10 each has a support shaft 11, the has the same function as the support wave 6 (Fig. 1). The support shaft 11 is by means of several Ball bearings 12 arranged along the support shaft 11 rotatably mounted. About the support shaft 11 rotatable in the Holding device 10 is on the underside of the Support device 10 arranged a magnet 13, the due to the magnetic forces, the support shaft 11 in the support device 10 holds.

Dadurch, daß die Stützwelle 11 außerhalb ihrer Rotationsachse drehbar gelagert ist, ist es möglich, im Gegensatz zum Stand der Technik eine Stützwelle zu verwenden, die einen deutlich geringeren Durchmesser aufweist als die Unterstützungswelle 6 nach dem Stand der Technik (Fig.1). Darüber hinaus dienen die Kugellager 12 nicht nur zur drehbaren Lagerung der Stützwelle 11, sondern bewirken eine Stabilisierung der Stützwelle 11 über die gesamte Arbeitsbreite der Längsschneidvorrichtung 2. Durch die Kugellager 12 werden die dünnen Stützwellen 11 in kleinen Abständen unterstützt, so daß eine Durchbiegung der Stützwelle 11 nicht stattfinden kann. Durch eine dünne Stützwelle 11 kann der Abstand zwischen dem Auflagepunkt der Materialbahn 5 auf der Stützwelle 11 und dem Schnittpunkt in der Längsschneidvorrichtung 2 gegenüber dem Stand der Technik deutlich verkürzt werden.In that the support shaft 11 outside its axis of rotation is rotatably mounted, it is possible in Contrary to the prior art, a support shaft too use a much smaller diameter has as the support shaft 6 according to the state the technology (Fig.1). The ball bearings also serve 12 not only for the rotatable mounting of the support shaft 11, but stabilize the support shaft 11 over the entire working width of the slitter 2. Through the ball bearings 12, the thin Support shafts 11 supported at small intervals, so that a deflection of the support shaft 11 does not take place can. By means of a thin support shaft 11, the distance between the point of contact of the material web 5 on the Support shaft 11 and the intersection in the slitter 2 clearly compared to the prior art be shortened.
