Description

Die Erfindung betrifft eine Tragwalzen-Wickelmaschine zum Aufwickeln von durch Längsschnitte unterteilten Materialbahnen, insbesondere von Papier- oder Kartonbahnen, auf Hülsen gemäß dem Oberbegriff des Patentanspruchs 1.The invention relates to a support roller winding machine for winding through Longitudinal cuts of divided material webs, in particular paper or cardboard webs, on sleeves according to the preamble of claim 1.

Zum Aufwickeln von Papier- oder Kartonbahnen zu Wickelrollen sind Tragwalzen-Wickelmaschinen bekannt, die zwei angetriebene Tragwalzen aufweisen, auf denen die Wickelrollen beim Aufwickeln nebeneinander mit fluchtenden Hülsen aufliegen. Die Tragwalzen-Wickelmaschinen weisen eine Rollenausstoßvorrichtung auf, die bei einem Rollenwechsel einen Satz fertiggewickelter Wickelrollen aus dem von den beiden Tragwalzen gebildeten Walzenbett ausstoßen. Der fertige Satz Wickelrollen wird dabei von der Ausstoßvorrichtung über den Scheitel einer Tragwalze auf eine Absenkbühne gedrückt und von dieser zum Entladen auf Flurniveau abgesenkt.Carrier roll winding machines are used for winding paper or cardboard webs into winding rolls known, which have two driven support rollers on which the When winding, the winding rolls lie side by side with the cores aligned. The Carrier roll winding machines have a roll ejection device, which at a Roll change a set of completely wound winding rolls from the one of the two Eject carrier rollers formed roller bed. The finished set of winding rolls is included from the ejection device over the top of a carrier roller to a lowering platform pressed and lowered to floor level for unloading.

Als Ausstoßvorrichtungen werden bekannterweise um die einlaufseitige Tragwalze in Richtung zum Walzenbett schwenkbare Ausstoßbalken (DE-OS 38 11 871) oder Ausstoßrollen eingesetzt, die an seitlichen, um die Achse der einlaufseitigen Tragwalze schwenkbaren Schwenkarmen freidrehbar gelagert ist (DE-OS 40 03 504).As ejection devices are known to be around the inlet-side support roller Ejection bar pivotable towards the roller bed (DE-OS 38 11 871) or Ejection rollers are used on the side, around the axis of the feed roller pivotable swivel arms is freely rotatable (DE-OS 40 03 504).

Die Stirnseite an Stirnseite gewickelten, bei der Papierherstellung tonnenschweren Wickelrollen eines Rollensatzes müssen beim Entladen aus der Wickelmaschine so voneinander getrennt werden, daß ihre Stirnseiten zum Kennzeichnen und Vorbereiten für die Verpackung frei zugänglich sind. Dazu werden benachbarte Wickelrollen von der Absenkbühne auf unterschiedlich langen Wegen in eine Anordnung mit versetzten Achsen rollengelassen. Dabei treten Schwierigkeiten auf, falls der Abstand zweier Stirnseiten voneinander zu gering ist, z. B. die Wickelrollen aneinander haften oder sich mit ihren Hülsenenden miteinander verhaken. In der Praxis werden aufwendige Führungselemente in die Absenkbühne eingearbeitet oder auf dem Boden befestigt, damit die Wickelrollen beim Herabrollen von der Absenkbühne sich auf die erforderliche Weise voneinander trennen. Absenkbühnen mit Führungselementen und Führungselemente auf dem Boden, z. B. ins Fundament eingearbeitete gekrümmte Führungsbahnen, sind konstruktiv aufwendig oder verlangen aufwendige Fundament-Feinarbeiten. Bei beengten Platzverhältnissen hinter der Wickelmaschine ist der für die Führungselemente auf dem Boden notwendige Platz häufig nicht vorhanden.The face-to-face wound, heavy in the paper production Winding rolls of a roll set must be so when unloading from the winding machine be separated from each other, that their end faces for labeling and preparation are freely accessible for packaging. For this purpose, adjacent winding rolls are removed from the Lowering platform on different lengths in an arrangement with staggered Axles rolled. Difficulties arise if the distance between two End faces from each other is too small, e.g. B. the winding rollers stick to each other or themselves interlock with their sleeve ends. In practice, they are complex Guide elements incorporated into the lowering platform or fastened to the floor, so that the winding rollers roll down from the lowering platform to the required Separate wise. Lowering platforms with guide elements and guide elements on the floor, e.g. B. curved guideways incorporated into the foundation, are structurally complex or require complex foundation work. At cramped space behind the winding machine is that for the guide elements Often there is no space on the floor.

Der Erfindung liegt die Aufgabe zugrunde, eine Tragwalzen-Wickelmaschine so zu verbessern, daß ohne großen konstruktiven Aufwand die Trennung der Wickelrollen auch bei beengten Platzverhältnissen gewährleistet ist.The invention is based on the object of a carrier roller winding machine improve that the separation of the winding rolls without great design effort is guaranteed even in confined spaces.

Diese Aufgabe wird mit den Merkmalen des Patentanspruchs 1 gelöst.This object is achieved with the features of patent claim 1.

Die gekrümmte Ausstoßvorrichtung nach der nach der Erfindung bewirkt, daß die Wickelrollen eines Rollensatzes beim Ausstoßen über die zweite Tragwalze auseinanderbewegt werden. Sie liegen anschließend mit größerem axialen Abstand voneinander auf der Absenkbühne, so daß sie ohne Probleme in eine versetzte Anordnung gerollt werden können.The curved ejection device according to the invention causes the Winding rolls of a set of rolls moved apart during ejection via the second support roller become. They are then at a greater axial distance from one another on the lowering platform so that it can be rolled into a staggered arrangement without any problems can be.

Die in Fig. 1 dargestellte Tragwalzen-Wickelmaschine weist zwei angetriebene Tragwalzen 1, 2 auf, die ein Walzenbett bilden, in dem die Wickelrollen 3 beim Aufwickeln auf den Tragwalzen 1, 2 aufliegen. Die Papier- oder Kartonbahn 4 wird von einer Längsschneideeinrichtung 5 in Einzelbahnen aufgeteilt, die anschließend durch den Spalt zwischen den Tragwalzen 1, 2 in das Walzenbett geführt werden, wo sie auf fluchtend aufgereihte Hülsen gewickelt werden. Oberhalb des Walzenbetts ist im Gestell der Wickelmaschine eine Druckrollensystem 6 angeordnet, mit dem sich zu Beginn der Aufwicklung das Auflagegewicht der Wickelrollen 3 auf den Tragwalzen 1, 2 erhöhen läßt, wenn das Eigengewicht der Wickelrollen 3 für die gewünschte Wickelhärte noch nicht ausreicht. An jeder Maschinenseite ist ein Führungskopf 7 vertikal beweglich gelagert, der jeweils von außen in die Hülse der Randrolle einfährt, um den Satz von Wickelrollen 3 beim Aufwickeln seitlich zu führen. Derartige Tragwalzen-Wickelmaschinen sind vielfach bekannt und z. B. in der DE-OS 32 07 461 beschrieben.The support roller winding machine shown in Fig. 1 has two driven Carrier rollers 1, 2, which form a roller bed in which the winding rollers 3 at Wind up on support rollers 1, 2. The paper or cardboard web 4 is from a slitter 5 divided into individual webs, which then by the gap between the support rollers 1, 2 are guided into the roller bed, where they on aligned sleeves are wound. Above the roller bed is in the frame the winding machine a pressure roller system 6 arranged with which at the beginning of Winding up increase the weight of the winding rollers 3 on the support rollers 1, 2 leaves when the dead weight of the winding rollers 3 for the desired winding hardness still not enough. A guide head 7 can be moved vertically on each machine side stored, each of which moves from the outside into the sleeve of the edge roller to the set of To guide winding rollers 3 laterally when winding. Carrier roll winding machines of this type are widely known and z. B. described in DE-OS 32 07 461.

An beiden Stirnseiten der einlaufseitigen Tragwalze 1 ist im Maschinengestell jeweils ein nach unten abgewinkelter Schwenkhebel 8 mittels einer Kolben-Zylinder-Einheit 9 um eine zur Drehachse der Tragwalze 1 koaxiale Achse schwenkbar gelagert. Die Hebel 8 an beiden Seiten der Maschinen tragen an ihrer Oberseite über die Arbeitsbreite reichende Rollenausstoßvorrichtung und eine Hülseneinlegeeinrichtung, die nachfolgend näher beschrieben werden:There is one in each of the machine frames on both end faces of the feed roller 1 on the inlet side downward angled pivot lever 8 by means of a piston-cylinder unit 9 an axis coaxial to the axis of rotation of the support roller 1 pivotally mounted. The levers 8 on both sides of the machines bear on the top over the working width reaching roller ejection device and a sleeve insertion device, the following are described in more detail:

Die Ausstoßvorrichtung enthält eine Ausstoßrolle 10, die sich über die Arbeitsbreite erstreckend am Ende eines gabelförmigen Lagerteils 11 gelagert ist, das außerhalb des Querschnittsbereich der Tragwalze 1 auf jedem Schwenkhebel 8 befestigt ist. Die Ausstoßrolle 10 ist so mittels der Kolben-Zylinder-Einheit 9 um die einlaufseitige Tragwalze 1 in Richtung zum Walzenbett schwenkbar. Beim Einschwenken legt sie sich an die fertiggewickelten Wickelrollen 3 an und drückt diese über die Tragwalze 2 auf eine Absenkbühne 12. Die Absenkbühne 12 ist hinter der auslaufseitigen Tragwalze 2 mittels einer Kolben-Zylinder-Einheit 13 hochschwenkbar angeordnet. Sie ist in Fig. 1 in ihrer hochgeschwenkten Stellung beim Aufwickeln dargestellt. In dieser Position dient sie zugleich als Schutzvorrichtung. Vor dem Ausstoßen eines Satzes von Wickelrollen 13 wird sie in eine in etwa waagerechte Position abgeschwenkt.The ejection device contains an ejection roller 10 which extends over the working width extending at the end of a fork-shaped bearing part 11 which is outside the Cross-sectional area of the support roller 1 is attached to each pivot lever 8. The Ejection roller 10 is so by means of the piston-cylinder unit 9 around the inlet side Carrier roller 1 can be pivoted in the direction of the roller bed. When it swings in, it lies down to the fully wound winding rolls 3 and presses them on the support roller 2 a lowering platform 12. The lowering platform 12 is behind the outlet-side support roller 2 arranged pivotably by means of a piston-cylinder unit 13. It is in Fig. 1 in shown their pivoted up position when winding. In this position it serves at the same time as a protective device. Before ejecting a set of winding rolls 13 it is swung into an approximately horizontal position.

Die Ausstoßrolle 10 ist in Fig. 2 detaillierter dargestellt:The ejection roller 10 is shown in more detail in FIG. 2:

Die Ausstoßrolle 10 besteht aus einzelnen zylinderförmigen Rollensegmenten 14, die auf einer gekrümmten Achse 15 frei drehbar gelagert sind. Die Rollensegmente 14 weisen eine axiale Länge von 500 mm - 1000 mm und einen Durchmesser von 150 mm - 250 mm auf. Um Markierungen auf den Wickelrollen 3 zu vermeiden, sind die Übergänge zwischen zwei Rollensegmenten ohne scharfe Kanten gestaltet, beispielsweise sind die Kanten der Rollensegmente abgerundet, oder die Rollensegmente 14 weisen zumindest an ihren Rändern eine konische Form auf. Die Achse 15 ist in Ausstoßrichtung (Pfeil 16) konvex gekrümmt, so daß die Rollensegmente 14 über die Arbeitsbreite bogenförmig entlang einer gekrümmten Linie angeordnet sind. Die Höhe h des Bogens, also die maximale Abweichung der Ausstoßfläche vom geradlinigen Verlauf in der Mitte der Maschine, beträgt abhängig von der Arbeitsbreite der Maschine zwischen 5 mm und 50 mm. Bei einer Arbeitsbreite von 5 m beträgt die Höhe h bevorzugt ca. 20 mm. Die Achse 15 ist in den Lagerteilen 11 an den Maschinenseiten verdrehsicher so gelagert, daß beim Ausstoßen der Wickelrollen 3 die sich an die Wickelrollen 3 anlegende Ausstoßkante in Ausstoßrichtung konvex gekrümmt ist. Wie in den Fig. 3 bis 5 dargestellt, werden die Wickelrollen 3 eines Rollensatzes so beim Ausstoßen aus dem Walzenbett bereits auf den Tragwalzen 1, 2 etwas gedreht, daß ihre Vorderseiten auffächern. Die Drehung jeder Wickelrolle 3 ist um so größer, je weiter sie außen im Rollensatz angeordnet ist. Die etwas gedrehten Wickelrollen 3 vergrößern beim Rollen auf die Absenkbühne 12 ihren axialen Abstand voneinander. Die in Achsrichtung nach außen wirkenden hohen Kräfte bewirken dabei eine Trennung selbst fest aneinanderhaftender Wickelrollen 3 voneinander auf den gewünschten axialen Abstand voneinander, wie in Fig. 5 dargestellt ist. Die Wickelrollen 3 können anschließend problemlos von der Absenkbühne in eine Position rollen gelassen werden, bei der die Stirnseiten zum Kennzeichnen und Vorbereiten für die Verpackung frei zugänglich sind.The ejection roller 10 consists of individual cylindrical roller segments 14 which on a curved axis 15 are freely rotatable. The roller segments 14 have an axial length of 500 mm - 1000 mm and a diameter of 150 mm - 250 mm on. In order to avoid markings on the winding rolls 3, the transitions are designed between two roller segments without sharp edges, for example Edges of the roller segments rounded, or at least the roller segments 14 have a conical shape at the edges. The axis 15 is in the ejection direction (arrow 16) convexly curved so that the roller segments 14 arcuate over the working width are arranged along a curved line. The height h of the arch, i.e. the maximum deviation of the discharge area from the straight line in the middle of the Machine, is between 5 mm and 50 depending on the working width of the machine mm. With a working width of 5 m, the height h is preferably approximately 20 mm. The axis 15 is mounted in the bearing parts 11 on the machine sides so that it cannot rotate Ejecting the winding rollers 3 in the discharge edge resting against the winding rollers 3 in Ejection direction is convexly curved. As shown in Figs. 3 to 5, the Winding rolls 3 of a set of rolls thus already open when ejected from the roll bed the support rollers 1, 2 rotated somewhat that their front sides fan out. The rotation each winding roll 3 is larger, the further it is arranged outside in the roll set. The somewhat rotated winding rolls 3 enlarge when rolling onto the lowering platform 12 their axial distance from each other. The high ones acting outwards in the axial direction Forces cause separation of even tightly adhering winding rolls 3 from each other to the desired axial distance from each other, as shown in Fig. 5 is. The winding rolls 3 can then easily from the lowering platform in a Position to be left at which the end faces for marking and Prepare for packaging are freely accessible.

Alternativ kann die Ausstoßrolle 10 aus Rollensegmenten 14 aufgebaut sein, die jeweils auf einer eigenen geraden Achse gelagert sind. Die Achsen der Rollensegmente 4 sind dann entlang einer gekrümmten Linie angeordnet, um den gewünschten bogenförmigen Verlauf der Ausstoßkante zu erhalten.Alternatively, the ejection roller 10 can be constructed from roller segments 14, each are stored on their own straight axis. The axes of the roller segments 4 are then arranged along a curved line to the desired arcuate Obtain the course of the ejection edge.

Anstelle einer Ausstoßrolle 10 kann die Ausstoßvorrichtung auch einen Ausstoßbalken mit einer festen, über die Arbeitsbreite entsprechend in Ausstoßrichtung konvex gekrümmten Ausstoßfläche 17 enthalten. Ebenso ist -wie in Fig. 1 dargestellt- die Kombination einer Ausstoßrolle 10 mit einer gekrümmten oder ungekrümmten Ausstoßfläche 17 möglich. Bei der Ausführungsform nach Fig. 1 enthält der Ausstoßbalken zugleich eine Einrichtung zum Einlegen neuer Hülsen 18. Die neuen Hülsen 18 liegen in einer an den Lagerteilen 11 unterhalb der Ausstoßfläche 17 befestigten Hülsenrinne. Die Ausstoßfläche 17 kann nach dem Ausstoßen der Wickelrollen 3 nach rückwärts aufgeklappt werden, um die neuen Hülsen 18 freizugeben und in das Walzenbett rollen zu lassen. Zu Beginn des Ausstoßens hebt die Ausstoßrolle 10 die Wickelrollen 3 von der Tragwalze 1 an und drückt sie in Richtung zur zweiten Tragwalze 2. Der letzte Teil des Ausstoßens über die Scheitellinie der Tragwalze 2 wird mittels der Ausstoßfläche 17 durchgeführt.Instead of an ejection roller 10, the ejection device can also have an ejection bar with a fixed convex over the working width in the direction of ejection curved ejection surface 17 included. Likewise, as shown in Fig. 1, the Combination of a discharge roller 10 with a curved or non-curved discharge surface 17 possible. In the embodiment according to FIG. 1, the ejection bar contains at the same time a device for inserting new sleeves 18. The new sleeves 18 are in a sleeve groove attached to the bearing parts 11 below the ejection surface 17. The Ejection surface 17 can after the ejection of the winding rolls 3 backwards be opened to release the new sleeves 18 and roll into the roller bed allow. At the beginning of the ejection, the ejection roller 10 lifts the winding rollers 3 off the support roller 1 and presses it towards the second support roller 2. The last part the ejection over the apex line of the support roller 2 is by means of the ejection surface 17th carried out.
