- the invention relates to large rolls of aluminum or steel strip, which have to be transported as semi-finished products for further processing from the rolling mill to a factory in which finished products, for example beer cans, are produced from the strip. These large packages are transported upright on pallets.

Abstract
Description
Die Erfindung betrifft eine in den zylindrischen Hohlraum eines Großwickels, wie einen Aluminium- oder Stahlbandwickel, einsetzbare nabenförmige Verformungssicherung in der Gestalt einer kreisförmigen Ronde, welche in ihrem Zentrum eine zylindrische Öffnung besitzt (US-A-4 015 711).The invention relates to a hub-shaped anti-deformation device which can be inserted into the cylindrical cavity of a large winding, such as an aluminum or steel band winding, in the form of a circular blank which has a cylindrical opening in its center (US Pat. No. 4,015,711).
Die Erfindung bezieht sich auf Großwickel aus Aluminium- oder Stahlband, welche als Halbfertigfabrikate zur Weiterverarbeitung vom Walzwerk zu einer Fabrik transportiert werden müssen, in welcher aus dem Band Fertigprodukte, beispielsweise Bierdosen, hergestellt werden. Diese Großwickel werden aufrechtstehend auf Paletten angeordnet transportiert. Es kann vorkommen, daß sich die ein hohes Gewicht besitzenden Wickel bei einer starken positiven oder negativen Beschleunigung des Transportfahrzeuges verschieben und gegeneinander stoßen. Dabei können die Wickel derart verformt werden, daß sie in der Fabrik nicht mehr abgearbeitet, d. h. abgewickelt werden können.The invention relates to large rolls of aluminum or steel strip, which have to be transported as semi-finished products for further processing from the rolling mill to a factory in which finished products, for example beer cans, are produced from the strip. These large packages are transported upright on pallets. It can happen that the coils, which have a high weight, shift and collide against one another when the transport vehicle accelerates strongly or negatively. The coils can be deformed in such a way that they are no longer processed in the factory, i. H. can be processed.
Es ist daher bekannt, wenigstens in das obere Ende des zylindrischen Hohlraumes des Wickels eine Verformungssicherung einzusetzen. Bekannte Verformungssicherungen für Großwickel bestehend aus mehreren kreisförmigen Sperrholzscheiben, welche miteinander verleimt sind.It is therefore known to use a deformation lock at least in the upper end of the cylindrical cavity of the winding. Known deformation safeguards for large wraps consisting of several circular plywood disks, which are glued together.
Diese bekannten Verformungssicherungen weisen insbesondere den Nachteil auf, daß sie infolge ihrer Starrheit die auf den Wickel ausgeübten und auf die Verformungssicherung übertragenen Radialkräfte nicht kompensieren können. Die Verformungssicherungen werden von diesen Kräften an ihrem äußeren Rand wieder in einzelne Scheiben zerlegt und von dem axial nach außen gerichteten Anteil der Kräfte aus dem Wickel herausgedrückt. Außerdem sind die bekannten Verformungssicherungen relativ kostspielig in der Herstellung und weisen ein verhältnismäßig hohes Gewicht auf.These known anti-deformation devices have the particular disadvantage that, due to their rigidity, they cannot compensate for the radial forces exerted on the winding and transmitted to the anti-deformation device. The deformation safeguards are broken down into individual disks at their outer edge by these forces and pressed out of the winding by the axially outward portion of the forces. In addition, the known deformation safeguards are relatively expensive to manufacture and have a relatively high weight.
Aus der US-A-4,015,711 ist eine Verformungssicherung bekannt, welche im wesentlichen topfförmig ausgebildet und im Boden mit einer kreisförmigen Öffnung versehen ist. Sie soll hauptsächlich bei Wickeln aus Papierband oder Kunststoffolien eingesetzt werden. Hinweise in der Veröffentlichung deuten darauf hin, daß diese bekannte Verformungssicherung einstückig aus Kunststoff hergestellt sein soll. Diese bekannte Verformungssicherung ist nicht stabil genug, um bei Großwickeln aus Aluminium- oder Stahlbändern als Verformungssicherung verwendet zu werden.From US-A-4,015,711 a deformation protection is known, which is essentially pot-shaped and is provided in the bottom with a circular opening. It is mainly used for wrapping paper tape or plastic films. Notes in the publication indicate that this known deformation protection should be made in one piece from plastic. This known deformation protection is not stable enough to be used as deformation protection in large windings made of aluminum or steel strips.
Aus der US-A-1,919,769 ist eine Verformungssicherung bekannt, welche ebenfalls eine topfförmige Gestalt aufweist, deren Boden jedoch in etwa trichterförmig ausgebildet ist. Diese bekannte Verformungssicherung soll in die Enden eines zylindrischen Wickelkernes eingesetzt werden, auf welchen Papierbänder gewickelt sind. Sie soll aus Metallblech hergestellt sein. Wenn eine solche bekannte Verformungssicherung so ausgestaltet werden sollte, daß sie für Großwickel aus Aluminium- oder Stahlbändern brauchbar wäre, dann müßten wesentlich stärkere Metallbleche verwendet werden, welche nicht mehr so einfach verformt werden können. Diese bekannte Verformungssicherung ist für den Einsatz bei Großwickeln - falls überhaupt brauchbar-- zu kostspielig.From US-A-1,919,769 a deformation protection is known, which also has a cup-shaped shape, but the bottom of which is approximately funnel-shaped. This known deformation protection is to be inserted into the ends of a cylindrical winding core on which paper tapes are wound. It is said to be made of sheet metal. If such a known deformation protection should be designed so that it would be useful for large windings made of aluminum or steel strips, then much stronger metal sheets would have to be used, which can no longer be deformed so easily. This well-known anti-deformation device is too expensive - if usable at all - for use with large coils.
Aus der US-A-3,567,146 ist eine Verformungssicherung für Wickel aus Papierbändern bekannt, welche aus zwei ineinandergesetzten topfförmigen Gebilden bestehen, welche durch einstückig angeformte Versteifungsstege miteinander verbunden und in einer bestimmten Lage zueinander gehalten sind. Wenn diese bekannte Verformungssicherung für Großwickel aus Aluminium-oder Stahlbändern ausgelegt werden müßte, würde dies zu einem unwirtschaftlichen Produkt führen.From US-A-3,567,146 a deformation protection for wraps of paper tapes is known, which consist of two nested pot-shaped structures, which are connected to each other by integrally molded stiffening webs and held in a certain position to each other. If this known deformation protection had to be designed for large coils made of aluminum or steel strips, this would lead to an uneconomical product.
Aus der US-A-3,627,220 ist eine einstückig aus Kunststoff gespritzte Verformungssicherung zum Einsetzen in die Enden von zylindrischen Papierrohren bekannt, auf welchen Wickel aus Papierbändern oder Kunststoffolien angeordnet sind. Diese bekannte Verformungssicherung besteht aus einem Ring mit U-förmigem Querschnitt, bei dem zwischen den beiden Schenkeln des U eine Mehrzahl von Versteifungsstegen angeordnet ist. Auch diese bekannte Verformungssicherung, würde sie für den Einsatz bei Großwickeln aus Aluminium- oder Stahlbändern ausgelegt, könnte nicht wirtschaftlich hergestellt werden.From US-A-3,627,220 a one-piece injection molded plastic locking device is known for insertion into the ends of cylindrical paper tubes, on which rolls of paper strips or plastic films are arranged. This known deformation protection consists of a ring with a U-shaped cross section, in which a plurality of stiffening webs is arranged between the two legs of the U. Even this well-known anti-deformation device, if it were designed for use with large windings made of aluminum or steel strips, could not be produced economically.
Der Erfindung liegt daher die Aufgabe zugrunde, eine Verformungssicherung zu schaffen, welche selbst bei starker radialer Krafteinwirkung auf den Wickel eine solche Form behält, daß der Wickel noch abgearbeitet werden kann und welche trotzdem in dem zylindrischen Hohlraum des Wickels zurück bleibt. Außerdem soll die neue Verformungssicherung leichter und kostengünstiger als die bekannten Verformungssicherungen herstellbar sein.The invention is therefore based on the object of creating a deformation lock which, even with strong radial force acting on the winding, maintains such a shape that the winding can still be processed and which nevertheless remains in the cylindrical cavity of the winding. In addition, the new deformation lock should be easier and cheaper to manufacture than the known deformation locks.
Diese Aufgabe ist erfindungsgemäß dadurch gelöst, daß die Ronde einen solchen U-förmigen Querschnitt aufweist, bei dem der waagerechte Schenkel konkav nach außen gekrümmt und der innere Schenkel gegenüber der Symmetrieachse nach innen zu derselben hin leicht geneigt ist.This object is achieved in that the round plate has such a U-shaped cross section, in which the horizontal leg is concavely curved outwards and the inner leg is slightly inclined towards the inside in relation to the axis of symmetry.
Eine solche Verformungssicherung erfüllt die vorstehend aufgezeigten Forderungen.Such protection against deformation fulfills the requirements outlined above.
Vorteilhafte Ausgestaltungen der Erfindung sind in den Ansprüchen 2 bis 4 enthalten, welche anhand der Figuren 1 bis 3 nachstehend näher erläutert ist. Es zeigen :
- Fig. 1 einen Großwickel mit eingesetzter Verformungssicherung,

- 3 shows the detail from two new, stacked anti-deformation devices according to FIG. 2.
Fig. 1 zeigt einen zum Transport bereiten Großwickel 1, der hochkant auf der Palette 2 abgestellt ist. Wenigstens in ein Ende, nämlich in das obere Ende des zylindrischen Hohlraums 3 des Großwickels 1 ist die Verformungssicherung 4 eingesetzt, welche verhindern soll, daß Kräfte, welche in Richtung der Pfeile auf den Großwickel 1 wirken, diesen derart verformen, daß er nicht mehr abgearbeitet werden kann.Fig. 1 shows a large roll 1 ready for transport, which is placed upright on the
Fig. 2 zeigt den Querschnitt der neuen Verformungssicherung 4. Sie besteht aus einem Ring mit U-förmigem Querschnitt und der zylindrischen Öffnung 5. Der U-förmige Querschnitt besteht aus dem leicht gewölbten waagerechten Schenkel 6, dem inneren Schenkel 7 und dem äußeren Schenkel 8. Der innere Schenkel 7 weist eine Schrägstellung zur Längsachse der Verformungssicherung auf und ist an seinem freien Ende mit der Stufe 9 versehen. Auf dem freien Ende des äußeren Schenkels 8 sind Stege 10 befestigt und zwar vorzugsweise drei Stück, welche jeweils um 120 Winkelgrade gegeneinander versetzt sind.Fig. 2 shows the cross section of the new deformation protection 4. It consists of a ring with a U-shaped cross section and the
Wenn die in Fig. 2 gezeigte Verformungssicherung 4 in den zylindrischen Hohlraum 3 des Großwickels 1 eingesetzt, radial angreifenden Kräften ausgesetzt wird, dann wird die daraus resultierende Energie im waagerechten Schenkel 6 in Verformungsenergie umgesetzt, welches dazu führt, daß er aus der gewölbten Gestalt in eine S-förmige Gestalt übergeht. Selbst wenn die radialen Kräfte so stark sei.n sollten, daß der äußere Schenkel 8 wegbricht, dann ist der Rest der Verformungssicherung noch in der Lage, den zylindrischen Hohlraum 3 derart zu erhalten, daß der Großwickel 1 abgearbeitet werden kann.If the deformation protection 4 shown in FIG. 2 is inserted into the
Fig. 3 verdeutlicht die Funktion der Stufe 9. Sie erleichtert das Stapeln einer größeren Anzahl der Verformungssicherungen.Fig. 3 illustrates the function of
Es hat sich herausgestellt, daß die neue Verformungssicherung 4 kostengünstiger und mit geringerem Gewicht hergestellt werden kann, wenn sie einstückig aus einem nicht steigfähigen Gemisch lignozellulosehaltiger Teilchen und einem wärmehärtenden Bindemittel gepreßt sind.It has been found that the new deformation lock 4 can be produced more cheaply and with less weight if it is pressed in one piece from a non-rising mixture of lignocellulosic particles and a thermosetting binder.
Bei dem nicht steigfähigen Gemisch handelt es sich beispielsweise um lignozellulosehaltige Faserstoffe, wie zerkleinerte und getrocknete Holzspäne, Bagassefasern u. ä., die mit einem wärmehärtenden Kunstharz, wie einem Melamin-, Harnstofformaldehyd- oder Phenolformaldehydharz vermischt sind. Anstelle der zerkleinerten und getrockneten Holz- oder Bagassefasern können aber auch Fasern anderer Werkstoffe, wie Glasfasern, Steinwolle oder Asbestfasern, allein oder mehrere derselben miteinander gemischt, verwendet werden, denen entsprechende, vorzugsweise organische Bindemittel zugesetzt sind.The non-climbing mixture is, for example, lignocellulosic fibrous materials, such as shredded and dried wood chips, bagasse fibers and the like. Ä., Which are mixed with a thermosetting synthetic resin, such as a melamine, urea formaldehyde or phenol formaldehyde resin. Instead of the shredded and dried wood or bagasse fibers, fibers of other materials, such as glass fibers, rock wool or asbestos fibers, alone or several of them mixed with one another, to which appropriate, preferably organic binders have been added can also be used.
