Description

Die Erfindung betrifft eine Ladevorrichtung für ein Folien­rollendrehlager mit zwei Drehlagern, von denen das eine oberhalb des anderen angeordnet ist.The invention relates to a loading device for a film roll rotary bearing with two rotary bearings, one of which is arranged above the other.

Bei den doppelstöckigen Folienrollenlagern konnte man bisher nur das untere Lager durch eine maschineneigene hydraulische Hebe­einrichtung mit einer Folienrolle beschicken. Für das Einlegen einer Folienrolle in das obere Rollendrehlager war man bisher auf ein separates Kranfahrzeug oder dergl. angewiesen. Dieses Ein­legen der schweren Folienrollen mittels Kranfahrzeug erfordert ein erhebliches Geschick und stellt eine betriebliche Gefahren­quelle dar.In the case of double-level foil roller bearings, it was previously only possible to load a foil roller into the lower bearing by means of a machine's own hydraulic lifting device. Previously, a separate crane vehicle or the like had to be used to insert a film roll into the upper roll pivot bearing. This loading of the heavy film rolls by means of a crane vehicle requires considerable skill and represents a source of operational risk.

Der Erfindung liegt die Aufgabe zu Grunde, eine Ladevorrich­tung für Folienrollendrehlager mit zwei Drehlagern zu schaffen, von denen das eine oberhalb des anderen angeordnet ist, durch welche die Beladung beider Lager vereinfacht wird. Insbesondere sollen beide Drehlager mit der gleichen Einrichtung beladen werden können. Darüber hinaus soll die Vorrichtung auch von ungeübten Kräften betätigt werden können. Insbesondere soll eine Beschädi­gung der Drehlager durch das Einlegen der schweren Rollen ver­mieden werden.The invention is based on the object of providing a loading device for film roll rotary bearings with two rotary bearings, one of which is arranged above the other, by means of which the loading of both bearings is simplified. In particular, both pivot bearings should be able to be loaded with the same device. In addition, the device should also be able to be operated by inexperienced forces. In particular, damage to the pivot bearings should be avoided by inserting the heavy rollers.

Diese Aufgabe wird bei der eingangs genannten Ladevorrichtung erfindungsgemäß dadurch gelöst, daß am unteren Rollendrehlager ein Paar Ladearme schwenkbar gelagert ist, deren Länge wenigstens gleich dem Abstand der beiden Rollendrehlager ist, das freie Ende jedes Ladearms eine Sperrklinke trägt und ein oder zwei hydrau­lisch schwenkbare Zwischenhebel vorgesehen sind, deren freie Enden mit dem bzw. den Ladearm(en) gelenkig und verschiebbar verbunden sind. Durch diese Ladevorrichtung ist es möglich, in die beiden Drehlager Folienrollen mit derselben zum Rollenlager gehörigen Einrichtung einzulegen. Die Folienrolle wird bei offenen Sperr­ klinken auf die Enden der beiden Ladearme gerollt und dann durch Schließen der Sperrklinken zunächst an den Ladearmenden gehalten. Nunmehr werden die Ladearme in die Horizontale oder mit den die Rolle haltenden Enden etwas über das untere Drehlager angehoben, so daß zu diesem ein geringes Gefälle besteht. Nunmehr kann nach dem Öffnen der Sperrklinken die Folienrolle über die Ladearme in das untere Rollendrehlager gerollt werden. Zur Beladung des oberen Lagers mit einer Folienrolle wird diese in gleicher Weise auf die abgesenkten Ladearme gerollt und durch Schließen der Sperrklinken gesichert. Dann werden die Ladearme hydraulisch mittels der Zwischenhebel hochgeschwenkt, bis sich die Welle der Folienrolle oberhalb des oberen Folienrollenlagers befindet. Dabei liegen die beiden Wellenenden der Folienrolle zweckmäßig einer schiefen Ebene an, auf der die Welle mit der Folienrolle in das obere Rollenlager einrollen kann. Die Sperrklinken werden dann geöffnet, so daß die Rolle in das Drehlager einrollt. In umgekehrter Weise können die Leerrollen aus dem Drehlager entnom­men werden.This object is achieved in the loading device mentioned above in that a pair of loading arms is pivotally mounted on the lower roller pivot bearing, the length of which is at least equal to the distance between the two roller pivot bearings, the free end of each loading arm carries a pawl and one or two hydraulically pivotable intermediate levers are provided are whose free ends are articulated and slidably connected to the loading arm (s). This loading device makes it possible to insert film rolls with the same device belonging to the roll bearing into the two rotary bearings. The film roll will lock when open pawls rolled onto the ends of the two loading arms and then held at the loading arm ends by closing the pawls. Now the loading arms are raised horizontally or with the ends holding the roller slightly above the lower pivot bearing, so that there is a slight slope to it. Now, after opening the pawls, the film roll can be rolled over the loading arms into the lower roll pivot bearing. To load the upper bearing with a film roll, it is rolled onto the lowered loading arms in the same way and secured by closing the pawls. Then the loading arms are hydraulically swiveled up using the intermediate lever until the shaft of the film roll is above the upper film roll bearing. The two shaft ends of the film roll are expediently on an inclined plane on which the shaft with the film roll can roll into the upper roller bearing. The pawls are then opened so that the roller rolls into the pivot bearing. Conversely, the empty rollers can be removed from the pivot bearing.

Nach der bevorzugten Ausführunsgform der erfindungsgemäßen Vorrichtung sind der bzw. die Zwischenhebel durch eine schwenk­bar angebrachte hydraulische Kolben/Zylinder-Einheit schwenkbar. Durch den Angriff der Kolben/Zylinder-Einheit an dem Zwischen­hebel ist es möglich, die Ladearme zur Beladung des oberen Rol­lenlagers um mehr als 90 ° hochzuschwenken. Ein so großer Schwenk­winkel ist nicht erreichbar, wenn die Kolben/Zylinder-Einheit an den Ladearmen direkt angreift. Vorzugsweise sind der bzw. die Zwischenhebel einarmig ausgebildet und greift die Kolbenstange der Kolben/Zylinder-Einheit im mittleren Bereich des bzw. der Zwischenhebel an. In diesem Falle ist das den Ladearmen abge­wandte Ende des Zwischenhebels am Maschinengestell schwenkbar angebracht. Der Zylinder der Kolben/Zylinder-Einheit ist ebenfalls am Maschinengestell schwenkbar angebracht, so daß sich die Ein­heit bei hochschwenkenden Ladearmen ebenfalls verschwenken kann.According to the preferred embodiment of the device according to the invention, the intermediate lever or levers can be pivoted by a pivotably mounted hydraulic piston / cylinder unit. By engaging the piston / cylinder unit on the intermediate lever, it is possible to swivel the loading arms for loading the upper roller bearing by more than 90 °. Such a large swivel angle cannot be achieved if the piston / cylinder unit directly engages the loading arms. The intermediate lever (s) are preferably designed with one arm and engage the piston rod of the piston / cylinder unit in the central region of the intermediate lever (s). In this case, the end of the intermediate lever facing away from the loading arms is pivotably attached to the machine frame. The cylinder of the piston / cylinder unit is also pivotally attached to the machine frame, so that the unit can also pivot when the loading arms are pivoted upwards.

Zweckmäßigerweise sind die freien Enden der Zwischenhebel in Langlöchern geführt, die in den Ladearmen ausgebildet sind. So wird erreicht, daß sich der Angriffspunkt der Zwischenhebel an den Ladearmen während der Schwenkbewegung der Ladearme ver­schieben kann.The free ends of the intermediate levers are expediently guided in elongated holes which are formed in the loading arms. This ensures that the point of engagement of the intermediate lever on the loading arms can move during the pivoting movement of the loading arms.

Zweckmäßigerweise sind die Sperrklinken an den Enden der Ladearme durch hydraulische Kolben/Zylinder-Einheiten betätigbar. Der Bedienungsmann kann daher durch hydraulische Steuermittel die Sperrklinken freigeben, wenn die Ladearme in die Einrollposition zum unteren bzw. oberen Rollendrehlager geschwenkt sind.The pawls at the ends of the loading arms can expediently be actuated by hydraulic piston / cylinder units. The operator can therefore release the pawls by hydraulic control means when the loading arms are pivoted into the roll-in position to the lower or upper roller pivot bearing.

Das obere Rollendrehlager ist im allgemeinen seitlich zum unteren Rollendrehlager versetzt.The upper roller pivot bearing is generally laterally offset from the lower roller pivot bearing.

Eine Ausführungsform der erfindungsgemäßen Vorrichtung wird nachfolgend an Hand der Zeichnung näher beschrieben, in der die Ladevorrichtung in der Seitenansicht vereinfacht dargestellt ist.An embodiment of the device according to the invention is described in more detail below with reference to the drawing, in which the loading device is shown in simplified form in the side view.

Die Figur zeigt ein doppelstöckiges Rollenlager mit hydrau­lischer Einlegevorrichtung für beide Lager. Das untere Folien­rollenlager ist mit der Bezugszahl 2 und das obere Folienrollen­lager mit der Bezugszahl 3 bezeichnet. Beide Lager sind am Maschi­nengestell fest angebracht. Um das untere Folienrollenlager 2 schwenkbar sind zwei parallele Ladearme 4, von denen in der Figur nur der vordere Arm sichtbar ist und deren Länge etwas größer als der gegenseitige Abstand der Lager 2 und 3 ist. An den freien Enden der Ladearme 4 ist je eine Sperrklinke 5 schwenkbar ange­bracht, die durch jeweils eine hydraulische Kolben/Zylinder-Ein­heit 10 geöffnet und geschlossen werden kann.The figure shows a two-story roller bearing with hydraulic insertion device for both bearings. The lower film roller bearing is designated by the reference number 2 and the upper film roller bearing by the reference number 3. Both bearings are firmly attached to the machine frame. Two parallel loading arms 4 are pivotable about the lower film roller bearing 2, of which only the front arm is visible in the figure and the length of which is somewhat greater than the distance between the bearings 2 and 3. At the free ends of the loading arms 4, a pawl 5 is pivotally attached, which can be opened and closed by a hydraulic piston / cylinder unit 10.

Die Schwenkung der Ladearme 4 wird hydraulisch bewirkt durch eine entsprechend dimensionierte hydraulische Kolben/Zylinder-­Einheit 8, die bei 11 an dem Maschinengestell schwenkbar aufge­ hängt ist. Die Kolbenstange 8a der Einheit 8 greift im mittleren Bereich eines Zwischenhebels 6 an und bewirkt beim Einziehen der Kolbenstange 8a die Schwenkung dieses einarmigen Hebels 6 um seinen Anlenkpunkt 12 am Maschinengestell. Das schwenkbare Ende 7 des Zwischenhebels 6, der ebenso wie der Ladearm 4 paarweise vor­handen ist, greift mit Zapfen in ein in dem Ladearm 4 ausgebil­detes Langloch 9.The pivoting of the loading arms 4 is effected hydraulically by a correspondingly dimensioned hydraulic piston / cylinder unit 8, which is pivoted at 11 on the machine frame depends. The piston rod 8a of the unit 8 engages in the central region of an intermediate lever 6 and, when the piston rod 8a is pulled in, causes this one-armed lever 6 to pivot about its articulation point 12 on the machine frame. The pivotable end 7 of the intermediate lever 6, which, like the loading arm 4, is provided in pairs, engages with pins in an elongated hole 9 formed in the loading arm 4.

Durch diese Konstruktion wird erreicht, daß eine durch die Kolben/Zylinder-Einheit 8 initiierte Schwenkung des Zwischen­hebels 6 um einen kleinen Winkel in eine Schwenkung der Lade­arme 4 um einen großen Winkel übersetzt wird. Auf diese Weise ist es möglich, die Ladearme 4 aus der dargestellten unteren Aufnahmeposition um mehr als 90 ° in die obere Übergabeposition an dem oberen Folienrollenlager 3 zu schwenken. Durch diese Ein­richtung können beide Rollenlager 2 und 3 wie folgt beladen wer­den.This construction ensures that a pivoting of the intermediate lever 6 initiated by the piston / cylinder unit 8 by a small angle is translated into a pivoting of the loading arms 4 by a large angle. In this way, it is possible to pivot the loading arms 4 from the lower receiving position shown by more than 90 ° into the upper transfer position on the upper film roller bearing 3. With this device, both roller bearings 2 and 3 can be loaded as follows.

Zunächst wird die Folienrolle 1 (Gewicht z.B. 1200 kg) bei geöffneten Sperrklinken z.B. von Hand auf die Enden der Lade­arme 4 gerollt. Nach dem Schließen der Sperrklinken werden dann die Ladearme 4 durch Einziehen der Kolbenstange 8a der Kolben/­Zylinder-Einheit 8 in die Horizontale gehoben, so daß die Rolle 1 von Hand in das untere Rollendrehlager 2 gerollt werden kann. (Folienrolle 1a). Zum Einlegen der Folienrolle 1b in das Rollen­lager 3 werden die Ladearme 4 wieder in die in der Figur darge­stellte Lage herabgeschwenkt. Die Folienrolle wird bei geöffne­ten Sperrklinken 5 auf die Enden der Ladearme 4 aufgerollt. Dann werden die Sperrklinken 5 wie dargestellt geschlossen, und die Ladearme 4 werden mit der so gesicherten Folienrolle durch Ein­ziehen der Kolbenstange 8a der hydraulischen Einheit 8 hochge­schwenkt, bis sich die Welle der Folienrolle 1b an der Schräg­fläche 3a des Rollenlagers 3 befindet. Nunmehr werden die Sperr­klinken 5 hydraulisch geöffnet, so daß die Rolle von den Lade­ armen 4 freigegeben wird und über die Flächen 3a in das obere Rollenlager 3 einrollen kann.First, the film roll 1 (weight, for example 1200 kg) is rolled onto the ends of the loading arms 4, for example by hand, with the pawls open. After closing the pawls, the loading arms 4 are then lifted into the horizontal by retracting the piston rod 8a of the piston / cylinder unit 8, so that the roller 1 can be rolled into the lower roller pivot bearing 2 by hand. (Film roll 1a). To insert the film roll 1b into the roll bearing 3, the loading arms 4 are pivoted down again into the position shown in the figure. The film roll is rolled up on the ends of the loading arms 4 with the pawls 5 open. Then the pawls 5 are closed as shown, and the loading arms 4 are pivoted up with the thus secured film roll by pulling in the piston rod 8a of the hydraulic unit 8 until the shaft of the film roll 1b is on the inclined surface 3a of the roller bearing 3. Now the pawls 5 are opened hydraulically, so that the roll of the drawer poor 4 is released and can roll over the surfaces 3a in the upper roller bearing 3.

Durch die erfindungsgemäße Vorrichtung ist es möglich, beide Rollenlager 2 und 3 ohne ein externes Hebegerät zu beladen. Die erfindungsgemäße Vorrichtung eignet sich für Herstellungsverfah­ren, bei denen Folien aus Kunststoff, Papier, Leichtmetall und dergl. als Bahn von Rollen abgerollt und kontinuierlich weiter­verarbeitet werden, z.B. bei der Kaschierung von Bahnmaterial, Tapetenherstellung, Kunststoff- oder Papiersackherstellung und ähnliche Prozesse.The device according to the invention makes it possible to load both roller bearings 2 and 3 without an external lifting device. The device according to the invention is suitable for manufacturing processes in which foils made of plastic, paper, light metal and the like are unrolled as a web from rolls and continuously processed, e.g. in the lamination of web material, wallpaper production, plastic or paper bag production and similar processes.
