Aus der DE 945 864 ist eine Hebevorrichtung für Papierrollen bekannt, mit einem Einsteckteil, an dem Spreizteile durch einen Konus nach außen drückbar sind, um einen Kraftschluss zwischen der Hebevorrichtung und dem zylindrischen Innenraum der Papierrolle zu schaffen. Ähnliche Vorrichtungen mit Spreizkonus sind auch aus der WO 90/06895 und der US 5,439,264 bekannt. Diesen bekannten Vorrichtungen ist gemeinsam, dass sie technisch aufwendig sind und einer sorgfältigen Bedienung bedürfen. Ferner ist ein sicherer Halt nicht immer gegeben.From DE 945 864 a lifting device for paper rolls is known, with a plug-in part on which spreading parts can be pressed by a cone to the outside to create a positive connection between the lifting device and the cylindrical interior of the paper roll.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass jedes Spreizteil als Reibrichtgesperre im Innenraum der Vorrichtung um eine Achse verschwenkbar gelagert, durch Federkraft in die Spreizposition verschwenkbar und durch eine der Federkraft entgegengesetzt wirkende Kraft aus der Spreizposition bewegbar ist.This object is achieved in that each spreading member mounted as Reibrichtgesperre in the interior of the device pivotable about an axis, by spring force in the Spreizposition pivotally and by a the spring force oppositely acting force from the Spreizposition is movable.
Die erfindungsgemäßen verschenkbaren Spreizteile passen sich der Funktion des Ein- und Ausfahrens an, wobei beim Einfahren der Vorrichtung mit ausgeschwenkten Spreizteilen, diese durch den Hohlraum der Last in die Vorrichtung eingeschoben werden und beim Heben der Vorrichtung nach oben sich selbstständig festziehen. Hierbei wird das Festziehen durch Federn unterstützt.The verschenkbaren spreading parts according to the invention adapt to the function of retraction and extension, which are inserted when retracting the device with pivoted expansion parts, these through the cavity of the load in the device and tighten when lifting the device upwards independently. Here, the tightening is supported by springs.
Vorzugsweise wird vorgeschlagen, dass die Achse der Spreizteile rechtwinklig zur Achse des Hohlraumes angeordnet ist. Ferner ist von Vorteil, wenn die Spreizteile als Exzenter ausgebildet sind, wobei die mit der Hohlraumwand einen Reibschluss erzeugende Außenfläche jedes Spreizteiles von dem an der Hohlraumwand nicht anliegenden Außenflächenbereich zum anliegenden Bereich in ihrem Radius zunimmt. Besonders vorteilhaft ist es, wenn bei von oben einsteckbarer Vorrichtung die Spreizteile durch die Federkraft nach unten verschenkbar sind, wobei beim Nachuntenverschwenken die Spreizteile nach außen über die Außenabmessungen der Vorrichtung vorragen.It is preferably proposed that the axis of the expansion parts is arranged at right angles to the axis of the cavity. Further, it is advantageous if the expansion parts are designed as eccentric, wherein the cavity wall with a frictional connection generating outer surface of each expansion part of the non-adjacent to the cavity wall outer surface area to the adjacent area increases in its radius. It is particularly advantageous if, when the device can be inserted from above, the expansion parts can be put down by the spring force, with the expansion parts projecting outward beyond the outer dimensions of the device when the device is pivoted downwards.
Ein sicheres Lösen der Vorrichtung wird dann erreicht, wenn an jedem Spreizteil eine einen Zug ausübende Einrichtung insbesondere ein Solenoid oder ein Zylinder-Kolben-Aggregat befestigt ist, durch die die Spreizteile aus der Spreizposition bewegbar sind. Hierbei kann die einen Zug ausübende Einrichtung über ein Zugmittel insbesondere ein Seil oder eine Kette am Spreizteil befestigt sein. Eine sichere Funktion ist dann gegeben, wenn die Kette auf einem mit dem Spreizteil verbundenen Zahnkranz aufliegt. Hierbei sollte der Zahnkranz koaxial zur Drehachse des Spreizteiles angeordnet sein.A secure release of the device is achieved if, attached to each expansion part, a train applying means, in particular a solenoid or a cylinder-piston unit, by means of which the expansion parts are movable from the expanded position. In this case, the device performing a train can be fastened to the expansion part via a traction means, in particular a cable or a chain. A safe function is given when the chain rests on a sprocket connected to the spreader. Here, the sprocket should be arranged coaxially to the axis of rotation of the expansion part.
Besonders vorteilhaft ist es, wenn die Vorrichtung ein zylindrisches, sich nach unten verjüngendes Außengehäuse aufweist, deren Außenwände senkrechte Schlitze für den Durchtritt der Spreizteile aufweisen. Ein Ausführungsbeispiel der Erfindung ist in den Zeichnungen in senkrechten Längsschnitten dargestellt.

Hierbei wird unter derselben Drehachse die gleichachsige Lage beider Drehachsen der Spreizteile 5, 6 verstanden.In the interior 4 of the device are two eccentric, plate-shaped spreading parts 5, 6 about the same horizontal axis of rotation 7 mounted independently pivotable. Here, the equiaxed position of both axes of rotation of the expansion parts 5, 6 is understood by the same axis of rotation.
Jedes Spreizteil ist in entgegengesetzte Drehrichtungen nach außen verschwenkbar, wobei im in Fig. 1 dargestellten eingefahrenen Zustand die Spreizteile im wesentlichen oberhalb der Achse 7 liegen, während im ausgeschwenkten, in Fig. 2 dargestellten Zustand die Spreizteile durch in der Gehäusewandung angeordnete, zur Vorrichtungsachse achsparallele Schlitze 8 über die Gehäusewandung hinausragen und mit einem Großteil der Spreizteilmasse unterhalb der Achse 7 liegen. Hierbei nimmt die mit der Hohlraumwand einen Reibschluss erzeugende Außenfläche jedes Spreizteiles 5, 6 von dem an der Hohlraumwand nicht anliegenden Außenflächenbereich zum anliegenden Bereich in ihrem Radius R zu.Each expansion is pivotable in opposite directions of rotation to the outside, wherein in the retracted state shown in Fig. 1, the expansion parts are substantially above the axis 7, while in the swung-out, shown in Fig. 2 state, the spreader through arranged in the housing, to the device axis paraxial Slots 8 protrude beyond the housing wall and lie with a large part of the Spreizteilmasse below the axis 7. In this case, the outer surface of each expansion part 5, 6, which generates a frictional connection with the cavity wall, increases in its radius R from the outer surface region, which is not adjacent to the cavity wall, to the adjacent region.
Das Verschwenken der Spreizteile 5, 6 nach unten kann durch deren Eigengewicht erfolgen. Unterstützt wird diese Bewegung vorzugsweise noch durch zwei Schraubenzugfedern 10a, 10b, die zwischen der jeweiligen Unterseite des Spreizteils und dem unteren Ende der Vorrichtung befestigt sind. An den Spreizteilen 5, 6 und/oder auf zusätzlichen Rädern 11 sind Zahnkränze 12 angeordnet, wobei diese Zahnkränze bzw. Räder drehbar auf der Achse 7 gelagert sind. Auf den Zahnkränzen 12 liegen Ketten 8, 9, die nach oben innerhalb des Innenraums 4 verlaufen und an der Unterseite der Anker von Solenoiden 13, 14 befestigt sind, die innerhalb des Innenraums 4 im oberen Bereich fest sind. Werden die Solenoide 13, 14 unter Spannung gesetzt, so werden die Ketten 8, 9 angezogen und hierdurch die Zahnkränze der Räder 11 so verschwenkt, dass die Spreizteile 5, 6 nach oben und damit eingezogen werden.The pivoting of the expansion parts 5, 6 down can be done by their own weight. This movement is preferably also supported by two helical tension springs 10a, 10b, which are fastened between the respective underside of the expansion part and the lower end of the device. To the spreader parts 5, 6 and / or on additional wheels 11 sprockets 12 are arranged, these sprockets or wheels are rotatably mounted on the axis 7. On the sprockets 12 are chains 8, 9, which extend upwardly within the interior 4 and are secured to the underside of the armature of solenoids 13, 14, which are fixed within the interior 4 in the upper region. If the solenoids 13, 14 are put under tension, the chains 8, 9 are tightened and thereby the sprockets of the wheels 11 are pivoted so that the spreader parts 5, 6 are pulled upwards and thus.
Statt der Solenoide 13, 14 können auch Zylinder-Kolben-Aggregate zum Lösen der Spreizteile 5, 6 eingesetzt werden. Die Solenoide oder Zylinder-Kolben- Aggregate können statt durch Ketten auch durch ein Seil mit den Rädern 11 und/oder Spreizteilen 5, 6 verbunden sein. Instead of the solenoids 13, 14 and cylinder-piston units for releasing the expansion parts 5, 6 can be used. The solenoids or cylinder-piston units can be connected instead of chains by a rope with the wheels 11 and / or spreading parts 5, 6.
