Description

Walzenanordnung für das Prägen von bahnformigen Materialien Roller arrangement for embossing sheet-like materials
Die Erfindung betrifft eine Walzenanordnung für das Prägen von bahnformigen Materialien, insbesondere von bahnformigen Papier- und Tissuematerialien, mit einer Patrize, auf der ein erstes Prägemuster aus einer Vielzahl voneinander beabstandeter Erhebungen angeordnet ist, und einer Matrize, auf der ein zweites Prägemuster aus einer Vielzahl voneinander beabstandeter Erhebungen angeordnet ist, wobei die Erhebungen des ersten Prägemusters in Freiräume des zweiten Prägemusters versenkbar sind.The invention relates to a roller arrangement for embossing web-shaped materials, in particular web-shaped paper and tissue materials, with a male on which a first embossing pattern consisting of a plurality of spaced-apart elevations is arranged, and a die on which a second embossing pattern consisting of a plurality is arranged at a distance from each other, the elevations of the first embossing pattern being retractable into free spaces of the second embossing pattern.
Wenn das erste Prägemuster und das zweite Prägemuster geometrisch so aufeinander abgestimmt sind, daß die Erhebungen wechselseitig an einer Anzahl von Punkten im wesentlichen übereinstimmen, ist eine Mikrorißprägung möglich, das heißt, durch die Geometrie der Prägemuster werden die Fasern des bahnformigen Materials gebrochen und deren Wasseraufnahmefähigkeit wird stark erhöht. Bei der Prägung von bahnförmigem Papier- und Tissuematerialien setzen sich nun Papierfasern und auch Staub in den Zwischenräumen des Prägemusters fest und verunreinigen Patrize und Matrize stark. Bisher mußte die Produktion unterbrochen werden, um die Walzen zu reinigen und wieder ein gutes Prägeergebnis zu erzielen.If the first embossing pattern and the second embossing pattern are geometrically coordinated with one another in such a way that the elevations mutually agree at a number of points, micro-crack embossing is possible, i.e. the geometry of the embossing pattern breaks the fibers of the web-like material and their water absorption capacity is greatly increased. When embossing web-shaped paper and tissue materials, paper fibers and also dust settle in the spaces between the embossing pattern and heavily contaminate the male and female molds. Until now, production had to be interrupted in order to clean the rollers and achieve a good embossing result again.
Es ist die Aufgabe der vorliegenden Erfindung, eine Walzenanordnung für das Prägen von bahnformigen Materialien so zu gestalten, daß eine Reinigung im laufenden Betrieb erfolgen kann.It is the object of the present invention to design a roller arrangement for embossing web-shaped materials so that cleaning can take place during operation.
Diese Aufgabe wird durch eine Walzenanordnung nach Anspruch 1 gelöst. Erfindungsgemäß ist vorgesehen, daß die Erhebungen des Prägemusters der Patrize oder der Matrize in in Um- fangsrichtung von Patrize oder Matrize beabstandeten Reihen angeordnet sind und daß zumindest eine Reinigungswalze vorgesehen ist, mit in Umfangsrichtung angeordneten Reinigungselementen, welche zwischen den Reihen aus den Erhebungen des Prägemusters der Patrize oder Matrize laufen. Zweckmäßigerweise ist sowohl für die Patrize als auch für die Matrize je eine Reinigungswalze vorgesehen, die außerhalb des Weges des bahnformigen Materials zum Zusammenwirken jeweils mit der Patrize oder Matrize aufgebaut sind. Während des Betriebes laufen dann die Reinigungselemente ständig zwischen den Erhebungen des jeweiligen Prägemusters und nehmen Papierfasern und Staub mit. Vorteilhaft sind die Reinigungselemente in Umfangsrichtung der Reinigungswalze beabstandet, so daß diese sich selbst reinigen.This object is achieved by a roller arrangement according to claim 1. According to the invention, it is provided that the elevations of the embossing pattern of the male or female are arranged in rows spaced in the circumferential direction from male or female and that at least one cleaning roller is provided, with cleaning elements arranged in the circumferential direction, which between the rows of the elevations of the embossed pattern the male or female run. A cleaning roller is expediently provided both for the male part and for the female part, each of which is constructed outside of the path of the web-shaped material for interacting with the male part or female part. During operation, the cleaning elements then run continuously between the elevations of the respective embossing pattern and take paper fibers and dust with them. The cleaning elements are advantageously spaced apart in the circumferential direction of the cleaning roller, so that they clean themselves.
Die Reinigungselemente können auch in Achsenrichtung der Reinigungswalze radial versetzt angeordnet sein, um einen ruhigen und rupffreien Lauf der Reinigungswalze zu gewährleisten.The cleaning elements can also be arranged so as to be radially offset in the axial direction of the cleaning roller in order to ensure that the cleaning roller runs smoothly and without jerking.
Zweckmäßigerweise sind die Reinigungselemente messerartige Reinigungsstege, deren Geometrie an die Geometrie des Prägemusters angepaßt ist.The cleaning elements are expediently knife-like cleaning webs, the geometry of which is adapted to the geometry of the embossing pattern.
Schließlich ist auch vorgesehen, daß die Erhebungen im Prägemuster schachbrettartig angeordnet sind, wobei die Form der einzelnen Erhebungen von nachgeordneter Bedeutung ist. Beispielsweise können die Erhebungen in Draufsicht kreuzförmig, quadratisch, oval oder dergleichen sein, solange beim Zusammenwirken zwischen Patrize und Matrize die gewünschte Mikrorißprägung erfolgen kann.Finally, it is also provided that the elevations are arranged in a checkerboard pattern, the shape of the individual elevations being of secondary importance. For example, the elevations can be cruciform, square, oval or the like in plan view, as long as the desired micro-crack embossing can take place when the male and female mold interact.

Figur 8 eine schematische Darstellung einer Reinigungswalze im Zusammenwirken mit der Patrize aus Figur 7; undFigure 8 is a schematic representation of a cleaning roller in cooperation with the male of Figure 7; and
Figur 9 eine schematische Darstellung des Zusammenwirkens von Patrize und Reinigungswalze nach Figur 7 bzw. Figur 8.FIG. 9 shows a schematic illustration of the interaction of the male and the cleaning roller according to FIG. 7 or FIG. 8.
Die in Figur 1 dargestellte Patrize 10 weist ein Prägemuster von aus in Umfangsrichtung der Patrize in Reihen 12, 14 angeordneten Erhebungen 6 auf, die in Draufsicht alle identisch und kreuzartig geformt sind, wobei die Erhebungen 16 weiterhin im Schachbrettmuster angeordnet sind. Mit der Patrize nach Figur 1 arbeitet eine Reinigungswalze 20 nach Figur 2 zusammen, auf der eine Vielzahl von Reinigungsstegen, 26, 26', 28 angebracht sind, welche ebenfalls in Umfangsrichtung in Reihen 22, 24 angeordnet sind. Die Reinigungsstege 26, 26' jeder Reihe sind in Umfangsrichtung voneinander beabstandet, damit die Reinigungswirkung beim Betrieb kurzzeitig unterbrochen wird und verhindert wird, daß sich die Reinigungsstege 26, 26', die nur mit kanppem Abstand die Erhebungen passieren, selbst verstopfen. Angesammelte Papierfasern können durch die Unterbrechung zwischen den Reinigungsstegen 26, 26' von der Reinigungswalze abgezogen werden. In axialer Richtung der Prägewalze 20 sind die Reinigungsstege 26, 28 radial voneinander versetzt, derart, daß in einer Gruppe aus Reinigungsstegen diese nacheinander zwischen den beabstandeten Reihen der Erhebungen laufen, so daß ein Rupfen der Reinigungswalze 20 in der Patrize verhindert wird. Die winkelige Anordnung der Reinigungsstege 26, 28 ist dabei derart getroffen, daß immer nur ein Reinigungssteg zur Zeit auf einer Axiallinie der Reinigungswalze 20 läuft.The male part 10 shown in FIG. 1 has an embossed pattern of elevations 6 arranged in rows 12, 14 in the circumferential direction of the male part, which are all identical and cruciform in plan view, the elevations 16 also being arranged in a checkerboard pattern. A cleaning roller 20 according to FIG. 2 works together with the male part according to FIG. 1, on which a plurality of cleaning webs 26, 26 ', 28 are attached, which are likewise arranged in rows 22, 24 in the circumferential direction. The cleaning webs 26, 26 'of each row are spaced apart from one another in the circumferential direction, so that the cleaning effect is briefly interrupted during operation and is prevented that the cleaning webs 26, 26', which only pass the elevations at a close distance, become blocked. Accumulated paper fibers can be pulled off the cleaning roller by the interruption between the cleaning webs 26, 26 '. In the axial direction of the embossing roller 20, the cleaning webs 26, 28 are radially offset from one another such that, in a group of cleaning webs, they run one after the other between the spaced rows of the elevations, so that the cleaning roller 20 is prevented from jerking in the male part. The angular arrangement of the cleaning webs 26, 28 is made such that only one cleaning web runs at a time on an axial line of the cleaning roller 20.
Figur 3 zeigt eine schematische Darstellung einer Variante einer Patrize 30, bei der die Erhebungen 36 zwar ebenfalls in Reihen 32, 34 und schachbrettartig angeordnet sind, jedoch mit größerem Abstand voneinander als bei der Ausführungsform nach Figur 1. Dementsprechend ist die Reinigungswalze 40 der Figur 4 mit breiteren Reinigungsstegen 44, 46', 48 ausgestattet, so daß auch hier die Papierfasern und der Staub zwischen den Reihen 32, 34 vollständig erfaßt werden.FIG. 3 shows a schematic representation of a variant of a male 30, in which the elevations 36 are also arranged in rows 32, 34 and in a checkerboard fashion, but at a greater distance from one another than in the embodiment according to FIG. 1 the cleaning roller 40 of FIG. 4 is equipped with wider cleaning webs 44, 46 ', 48, so that here too the paper fibers and the dust between the rows 32, 34 are completely captured.
Figur 5 zeigt den Laufweg A der Reinigungswalze 20 zwischen den Erhebungen des Prägemusters der Patrize 10 aus Figur 1. Durch die geometrische Abstimmung der Form der Erhebungen und der Dimension der Reinigungsstege wird sichergestellt, daß sämtliche Fasern und sämtlicher Staub von der Oberfläche der Prägewalze abgenommen werden, so daß ein gutes Prägeergebnis erzielt wird. Die Verhältnisse für die Patrize 30 nach Figur 3 und der Laufweg B der Reinigungswalze 40 nach Figur 4 sind in Figur 6 gezeigt.FIG. 5 shows the path A of the cleaning roller 20 between the elevations of the embossing pattern of the male part 10 from FIG. 1. The geometrical coordination of the shape of the elevations and the dimension of the cleaning webs ensures that all fibers and all dust are removed from the surface of the embossing roller , so that a good embossing result is achieved. The relationships for the male part 30 according to FIG. 3 and the path B of the cleaning roller 40 according to FIG. 4 are shown in FIG. 6.
Figur 7 zeigt ein drittes Ausfuhrungsbeispiel einer Patrize mit einem Muster regelmäßig beabstandeter, im wesentlichen rechtwinkliger Erhebungen 50, die in ihrer Umfangskontur leicht konvex ausgebildet sind. Ein Muster für eine mögliche zugehörige Reinigungswalze ist in Figur 8 gezeigt. Die in Umfangsrichtung verlaufenden Reinigungsstege 52 sind entsprechend den Beabstandungen der Erhebungen 50 der Patrize gemäß Figur 7 mit horizontal verlaufenden Stegabschnitten 54 versehen, wobei in Axialrichtung benachbarte Stegabschnitte 54 durch einen Freiraum 56 voneinander getrennt sind. Das Zusammenwirken von Patrize nach Figur 7 mit der Reinigungswalze nach Figur 8 ist in Figur 9 veranschaulicht.FIG. 7 shows a third exemplary embodiment of a patrix with a pattern of regularly spaced, essentially rectangular elevations 50 which are slightly convex in their peripheral contour. A pattern for a possible associated cleaning roller is shown in FIG. 8. The cleaning webs 52 running in the circumferential direction are provided with horizontally running web sections 54 in accordance with the spacing of the elevations 50 of the male part according to FIG. 7, web sections 54 adjacent in the axial direction being separated from one another by a free space 56. The interaction of the male part according to FIG. 7 with the cleaning roller according to FIG. 8 is illustrated in FIG. 9.
