Wickelmaschine zum Aufwickeln von Materialbahnen, insbesondere Papier- oder KartonbahnenWinding machine for winding material webs, especially paper or cardboard webs
Technisches GebietTechnical field
Die Erfindung betrifft eine Wickelmaschine zum Aufwickeln von Materialbahnen, insbesondere Papier- oder Kartonbahnen, auf Wickelhüisen, bei der die von einer Vorratsrolle abgezogene und durch Längsschneiden in Einzelbahnen aufgeteilte Materialbahn an einzelnen Wickelstationen aufgewickelt wird, die jeweils aus zwei quer zur Bahn verfahrbaren Wickelböcken bestehen.The invention relates to a winding machine for winding material webs, in particular paper or cardboard webs, on winding sleeves, in which the material web drawn off from a supply roll and divided by longitudinal cutting into individual webs is wound up at individual winding stations, each of which consists of two winding stands which can be moved transversely to the web.
Stand der TechnikState of the art
Um die Zugspannung jeder Wickelrolle beim Aufwickeln individuell regein zu können, sind nach der deutschen Patentanmeldung P 40 12 979.9 die die Wickelrollen haltenden, an den Wickelböcken befestigten Führungsköpfe jeweils mit einem Drehantrieb verbunden. Damit die Zugspannungen beim Aufwickeln auf unterschiedliche Werte als beim Längsschneiden eingestellt werden können, wird die Zugspannung der Einzelbahnen nach dem Längsschneiden und vor dem a Aufwickeln durch reibschlüssiges Führen über eine angetriebene Walze unterbrochen. Um den Reibschluss an der angetriebenen Walze zu erzeugen, klemmt eine freilaufende, gegen die angetriebene Walze andrückbare Rolle die Einzelbahnen ein. Damit die andrückbare Rolle bei geringem Durchmesser die erforderliche Stabilität auf eist, ist sie aus einzelnen, jeweils freilaufend gelagerten Segmenten von vorzugsweise 100 mm - 500 mm Länge aufgebaut, die zurIn order to be able to individually regulate the tension of each winding roll when winding up, according to the German patent application P 40 12 979.9, the guide heads holding the winding rolls and fastened to the winding stands are each connected to a rotary drive.

Vermeidung von Markierungen gummiert sind.Avoiding marks are rubberized.
Bei breiten Wickelmaschinen (Bahnbreiten 8 m und mehr) hat es sich als schwierig gezeigt, den erforderlichen Anpreßdruck der Rolle an die angetriebene Walze gleichmäßig über die Arbeitsbreite aufzubringen.With wide winding machines (web widths 8 m and more), it has proven difficult to apply the required contact pressure of the roll to the driven roller evenly over the working width.
Darstellung der ErfindungPresentation of the invention
Der Erfindung liegt die Aufgabe zugrunde, eine gattungsgemäße Wickeimaschine nach der Anmeldung P 40 12 979.9 so zu verbessern, daß über die gesamte Arbeitsbreite ein gleichmäßiger Anpreßdruck der frei drehbaren Rolle an die angetriebene Walze aufgebracht werden kann.The invention has for its object to improve a generic Wickei machine according to the application P 40 12 979.9 so that a uniform contact pressure of the freely rotatable roller can be applied to the driven roller over the entire working width.
Diese Aufgabe wird mit den kennzeichnenden Merkmalen des Patentanspruchs 1 gelöst.This object is achieved with the characterizing features of patent claim 1.
Darüber hinaus bietet die erfindungsgemäße Wickelmaschine die Möglichkeit, den Anpreßdruck über die Arbeitsbreite variabel zu gestalten, um die Zugspannung an jeder einzelnen Wickelstation in Abhängigkeit vom Wickelaufbau zu beeinflussen.In addition, the winding machine according to the invention offers the possibility of making the contact pressure variable over the working width in order to influence the tensile stress at each individual winding station as a function of the winding structure.
Die Unteransprüche enthalten bevorzugte, da besonders vorteilhafte Ausgestaltungen der Erfindung.The subclaims contain preferred, since particularly advantageous, embodiments of the invention.
Während der Aufbau aus Leichtmetall nach Anspruch 2 die Durchbiegung aufgrund des Eigengewichts minimiert, enthalten die Ansprüche 3 und 4 konstruktiv besonders vorteilhafte Ausgestaltungen. Patentanspruch 5 enthält eine Stützwalzen-Wickelmaschine, bei der vorteilhaft die angetriebene Stützwalze zugleich als angetriebene Walze zur Zugunterbrechung dient.While the light metal structure according to claim 2 minimizes the deflection due to its own weight, claims 3 and 4 contain structurally particularly advantageous configurations. Claim 5 contains a backup roller winding machine, in which advantageously the driven backup roller also serves as a driven roller for interrupting the train.

Wege zur Ausführung der ErfindungWays of Carrying Out the Invention
Die von einer nicht dargestellten Vorratsrolle abgezogene Materialbahn 1 , im vorliegenden Beispiel eine Papierbahn, wird von Leitrollen 2 bis 7 von oben an eine angetriebene Stützwalze 8 geführt. Zu beiden Seiten der Stützwalze 8 sind Wickelstationen 9, 10 angeordnet, die jeweils aus zwei parallel zur Stützwalzenachse verfahrbaren Wickelböcken 11, 12 bestehen. Jeder Wickelbock 11 , 12 trägt an seiner Oberseite einen radial zur Stützwalze 8 verfahrbaren Schlitten 13, 14, an dem ein Führungskopf 15, 16 mit seinem Drehantrieb 17, 18 befestigt ist. Die Führungsköpfe 15, 16 sind zum Halten und Antreiben der Wickelrollen 19, 20 in deren Wickelhülsen einfahrbar.The web of material 1 drawn off from a supply roll (not shown), in the present example a paper web, is guided by guide rollers 2 to 7 from above to a driven support roller 8. On both sides of the support roller 8 there are winding stations 9, 10, each consisting of two winding stands 11, 12 which can be moved parallel to the support roller axis. Each winding block 11, 12 carries on its upper side a slide 13, 14 which can be moved radially to the support roller 8 and on which a guide head 15, 16 is fastened with its rotary drive 17, 18. The guide heads 15, 16 are retractable for holding and driving the winding rollers 19, 20 in their winding tubes.
<*<*
Zwischen den Leitwalzen 4 und 5 verläuft die Bahn 1 an der Einlaufseite oberhalb der Stützwalze 8 in etwa waagerecht, anschließend wird sie von den Leitrollen 5, 6 jeweils nach unten zu der etwas versetzt oberhalb der Stützwalze 8 angeordneten Leitrolfe 7 umgelenkt. Im Bereich zwischen den Leitrollen 6 und 7 ist eine Längsschneideeinrichtung 21 mit Kreismesser¬ paaren angeordnet, die zur Einstellung verschiedener Formatbreiten der Einzelbahnen quer zur Bahnlaufrichtung verstellbar sind. Vor der Längsschneideeinrichtung 21 befindet sich zwischen den Leitrollen 5 und 6 eine Breitstreckeinrichtung 22. Die mit möglichst geringem Abstand von der Stützwalze 8 angeordnete Leitrolle 7 lenkt die beim Längsschneiden erzeugten Einzelbahnen 1 in etwa horizontal an die Stützwalze 8, von der sie umfänglich anliegend zu den Wickelstationen 9, 10 geführt werden.Between the guide rollers 4 and 5, the web 1 runs approximately horizontally on the inlet side above the support roller 8, then it is moved by the Guide rollers 5, 6 are each deflected downward to the guide roller 7 arranged somewhat offset above the support roller 8. In the area between the guide rollers 6 and 7 there is a longitudinal cutting device 21 with pairs of circular knives which are adjustable transversely to the web running direction in order to set different format widths of the individual webs. In front of the longitudinal cutting device 21 there is a spreader device 22 between the guide rollers 5 and 6. The guide roller 7, which is arranged as close as possible from the support roller 8, guides the individual webs 1 produced during the longitudinal cutting approximately horizontally to the support roller 8, from which they lie circumferentially to the Winding stations 9, 10 are performed.
Oberhalb des von den Bahnen 1 umschlungenen Bereichs der Stützwalze 8 erstreckt sich zwischen der Scheitellinie der Stützwalze 8 und den einlaufseitigen Wickelstationen 9 über die gesamte Arbeitsbreite eine biegesteife Traverse 23, die in Fig. 2 vergrößert dargestellt ist.Above the area of the support roller 8 wrapped around by the webs 1, a rigid cross-member 23 extends between the apex line of the support roller 8 and the inlet-side winding stations 9, which is shown enlarged in FIG. 2.
An der Unterseite der Traverse 23 ist eine biegeelastische Achse 24 parallel zur Stützwalzenachse mittels Halterungen 25 in Richtung zur Stützwalze schwenkbar befestigt. Auf der Achse 24 sind nebeneinander Rollensegmente 26 einzeln frei drehbar gelagert, die jeweils aus einem hohlzylinderförmigen Grundkörper 27 aus Leichtmetall, vorzugsweise aus Aluminium, bestehen, auf dessen Mantelfläche eine glatte Schicht 28 aus Gummi aufgebracht ist. An den beiden axialen Enden jedes Roilensegmentes 26 ist in den Grundkörper 27 ein Radiallager 29 eingepaßt, dessen innerer Laufring auf der Achse 24 befestigt ist. Die Roliensegmente 26 weisen eine Länge von 100 mm bis 500 mm auf.On the underside of the crossmember 23, a flexurally elastic axis 24 is fastened pivotably in the direction of the support roller parallel to the support roller axis by means of brackets 25. On the axis 24, roller segments 26 are individually rotatably mounted one next to the other, each consisting of a hollow cylindrical base body 27 made of light metal, preferably aluminum, on the outer surface of which a smooth layer 28 of rubber is applied. At the two axial ends of each roller segment 26, a radial bearing 29 is fitted into the base body 27, the inner race of which is fastened on the axis 24. The roller segments 26 have a length of 100 mm to 500 mm.
Die Halterungen 25 sind an beiden Enden der Achse 24 und jeweils zwischen zwei Rollensegmenten 26 angeordnet. Sie weisen in etwa die Form einer Scheibe mit einer zentralen Bohrung für die Achse 24 und zwei in etwa entgegengesetzte laschenförmigen Verbreiterungen auf. An einer der Verbreiterungen sind die Halterungen 25 an der Traverse 23 angelenkt, an der gegenüberliegenden Verbreiterungen ist jeweils das Ende des Kolbens 30 einer hydraulischen oder pneumatischen Kolben-Zylinder-Einheit 30, 31 gelenkig befestigt, deren Zylinder 3T an der Traverse 23 befestigt ist. Die Kolben-Zylinder-Einheiten 30, 31 drücken als Stellelemente die Halterungen 25 mit den daran gelagerten Rollensegmenten 26 mit individuell einstellbarer Kraft gegen die Stützwalze 8 im von den Bahnen 1 umschlungenen Bereich, um die Zugspannungen der Bahnen 1 vor den Wickelstationen 9, 10 zu unterbrechen. Der Anpreßdrücke der Kolben-Zylinder-Einheiten 30, 31 werden jeweils so gesteuert, daß sich über die Arbeitsbreite eine gleichmäßige Linienkraft im Bereich zwischen 5 und 25 N/cm einstellt.The brackets 25 are arranged at both ends of the axis 24 and in each case between two roller segments 26. They have approximately the shape of a disk with a central bore for the axis 24 and two approximately opposite lug-shaped widenings. The brackets 25 are articulated to the cross member 23 on one of the widenings, and the end of the piston 30 of a hydraulic or pneumatic piston-cylinder unit 30, 31, the cylinder 3T of which is attached to the cross member 23, is articulated on the opposite widenings. The piston-cylinder units 30, 31 press the brackets 25 with the roller segments 26 mounted thereon with individually adjustable force against the support roller 8 in the area wrapped by the webs 1 as actuating elements in order to interrupt the tensile stresses of the webs 1 in front of the winding stations 9, 10. The contact pressures of the piston-cylinder units 30, 31 are each controlled so that a uniform line force in the range between 5 and 25 N / cm is established over the working width.
Im beschriebenen Ausführungsbeispiel dient die Stützwalze 8 nicht nur zum Antreiben der Wickelrolle 19, 20, sondern auch als angetriebene Walze, um in Zusammenarbeit mit den Rollensegmenten 26 die Zugspannung der Bahnen 1 vor den Wickelstationen 9, 10 zu unterbrechen. Dies ist möglich, da die zum Aufwickein erforderliche Zugspannung hinter der Klemmsteile von den Antrieben 17, 18 über die Führungsköpfe 15, 16 aufgebracht wird. Bei Wickeimaschinen ohne angetriebene Führungsköpfe oder ohne Stützwalze wird im Maschinengestell eine getrennte angetriebene Gegenwalze für die Rollensegmente 26 zur Unterbrechung des Bahnzugs angeordnet. In the exemplary embodiment described, the support roller 8 serves not only to drive the winding roller 19, 20, but also as a driven roller in order to interrupt the tension of the webs 1 in front of the winding stations 9, 10 in cooperation with the roller segments 26. This is possible because the tension required for winding up is applied behind the clamping parts by the drives 17, 18 via the guide heads 15, 16. In the case of winding machines without driven guide heads or without a support roller, a separate driven counter-roller for the roller segments 26 is arranged in the machine frame to interrupt the web tension.
