Beschreibung description
Die vorliegende Erfindung bezieht sich auf einen Schwerlastboden gemäss dem Oberbegriff des Anspruchs 1 und einen Lagerbehälter gemäss dem Oberbegriff des Anspruchs 9. The present invention relates to a heavy-duty floor according to the preamble of claim 1 and a storage container according to the preamble of claim 9.
Lagerbehälter der genannten Art sind bekannt. Sie werden für das Einlagern von schweren Kleinteilen in Lagerregalen sowie für deren Transport benötigt. Solche Lagerbehälter bestehen in der Regel aus Kunststoff, wobei die Wände und der Boden einstückig gefertigt, das heisst in einem Stück gegossen bzw. gespritzt sind. Ihr Schwerlastboden weist typischerweise auf der Bodenunterseite gitterartig angeordnete Versteifungsrippen auf, was bei den gebräuchlichen Lastanforderungen eine Bodendicke von 15 bis 20 Millimetern bewirkt. Werden die Lagerbehälter mit dem Lagergut in Hochregallagern abgestellt, addieren sich die Ubermasse der Behälterböden merklich, was einen Verlust an teurem Lagerraum bedeutet. Zudem ist das Aufnahmevolumen der Lagerbehälter (bei vorgeschriebenen Aus-senabmessungen) kleiner als bei Lagerbehältern ohne Schwerlastboden. Dessen ungeachtet werden für automatisierte Lager Lagerbehälter mit hoher Masshaltigkeit verlangt, wodurch dauernd Kompromisse zwischen Platzverlust und Steifigkeit des Behälterbodens eingegangen werden müssen. Storage containers of the type mentioned are known. They are required for storing heavy small parts on storage racks and for transporting them. Storage containers of this type generally consist of plastic, the walls and the bottom being produced in one piece, that is to say being cast or injection-molded in one piece. Your heavy-duty floor typically has stiffening ribs arranged on the underside of the floor, which results in a floor thickness of 15 to 20 millimeters for the usual load requirements. If the storage containers with the goods are placed in high-bay warehouses, the excess mass of the container bottoms add up noticeably, which means a loss of expensive storage space. In addition, the storage volume of the storage containers (given the prescribed external dimensions) is smaller than that of storage containers without a heavy-duty base. Regardless of this, storage containers with high dimensional accuracy are required for automated warehouses, which means that compromises have to be constantly made between loss of space and rigidity of the container base.
Ein weiterer Nachteil der bekannten Lagerbehälter mit Schwerlastboden ist, dass im Boden unter Last ein Kriechvorgang eintritt, der zu einer dauernden Verformung führt, wenn die Stapelbehälter -was die Regel ist - aus Kunststoff gefertigt sind. Damit werden die für einen Transport auf Rollbahnen ohnehin schlecht tauglichen gitterverstärkten Schwerlastböden für diesen Zweck völlig unbrauchbar. Another disadvantage of the known storage containers with a heavy-duty base is that a creeping process occurs in the base under load, which leads to permanent deformation if the stacking containers - which is the rule - are made of plastic. As a result, the grid-reinforced heavy-duty floors, which are anyway unsuitable for transport on runways, are completely unusable for this purpose.
Weiter sind dreischichtige Verbundplatten bekannt, deren Aussenschichten aus Aluminiumblech bestehen und deren Mittelschicht aus einem Kunstwerkstoff, vorzugsweise Schaumstoff gefertigt ist. Diese Verbundplatten werden als Wand- und Fassadenverkleidungen in Gebäuden eingesetzt. Furthermore, three-layer composite panels are known, the outer layers of which consist of aluminum sheet and the middle layer of which is made of a plastic, preferably foam. These composite panels are used as wall and facade cladding in buildings.
Die vorliegende Erfindung stellt sich die Aufgabe, einen Schwerlastboden zu schaffen, der in Verbindung mit einem Lagerbehälter die genannten Nachteile beseitigt. Zudem sollte dessen Herstellung so preisgünstig sein, dass die Herstellungskosten des Lagerbehälters insgesamt nicht höher sind als für einen nach dem Stand der Technik gefertigten. The present invention has for its object to provide a heavy-duty floor that eliminates the disadvantages mentioned in connection with a storage container. In addition, its production should be so inexpensive that the overall manufacturing costs of the storage container are not higher than for a manufactured according to the prior art.
Erfindungsgemäss wird diese Aufgabe gelöst durch die kennzeichnenden Merkmale der Ansprüche 1 und 9. According to the invention, this object is achieved by the characterizing features of claims 1 and 9.
Durch die Erfindung sinkt die Bodenverformung unter den heute üblichen Lastvorschriften auf weniger als 10% derjenigen Bodenverformungen, die bei den bekannten Stapelbehältern auftreten. Die Erfindung hat zudem den Vorteil, dass sie einem weit grösseren Belastungsbereich gerecht werden kann, wenn für die Aussenschichten die Blechdicken so gewählt werden, dass die auftretende Verformung im rein elastischen Verformungsbereich bleibt. Schon eine geringfügige Verdickung der Bleche bewirkt eine starke Erhöhung der Belastbarkeit des Bodens, wobei sich der davon abhängige Raumverlust in praktisch vernachlässigbarer Grössenord-nung bewegt. By means of the invention, the floor deformation drops under the current load regulations to less than 10% of the floor deformations which occur in the known stacking containers. The invention also has the advantage that it can cope with a much larger load range if the sheet thicknesses are selected for the outer layers in such a way that the deformation that occurs remains in the purely elastic deformation range. Even a slight thickening of the sheets results in a strong increase in the load-bearing capacity of the floor, with the loss of space depending on it moving in a practically negligible order of magnitude.
Anhand der beiliegenden schematischen Zeichnung wird die Erfindung beispielsweise erläutert. Es zeigen. The invention is explained, for example, with the aid of the attached schematic drawing. Show it.
Fig. 1 eine perspektivische Darstellung eines Lagerbehälters, 1 is a perspective view of a storage container,
Fig. 2 einen Schnitt längs der Linie II-II in Fig. 1 und Fig. 2 shows a section along the line II-II in Fig. 1 and
Fig. 3 ein Detail aus Fig. 2 in vergrösserter Darstellung. Fig. 3 shows a detail of Fig. 2 in an enlarged view.
Der Lagerbehälter (Fig. 1 ) weist einen die Seitenwände bildenden Kunststoffrahmen 1 auf, der fest mit einem Boden 2 verbunden ist. Der Boden 2 ist mit seinen Rändern in den Rahmen 1 eingegossen und wird durch eine dreischichtige Verbundplatte gebildet. Seine beiden Aussenschichten bestehen aus Feinblech (Blech bis 3 Millimeter). Vorzugsweise wird Stahl- oder Aluminiumblech mit einer Dicke von 0,4 bis 0,5 Millimeter bzw. 0,5 bis 0,8 Millimeter verwendet. Sollten die heute üblichen Belastungsanforderungen wesentlich steigen, könnten auch dickere Bleche verwendet werden. Die Mittelschicht 4 besteht aus Grau-, Well- oder Hartpappe (Pavatex) und dgl. und hat eine Dicke von vorzugsweise 4 bis 9 Millimetern, wobei 6,5 bis 7,5 Millimeter am geeignetsten erscheint. Obwohl hier namentlich Pappe als Material für die Mittelschicht 4 genannt ist, eignet sich jeder plattenförmige Werkstoff, der im wesentlichen analog Pappe ist, das heisst, der übwiegend aus Pflanzenfasern durch Verfilzen, Verleimen und Pressen hergestellt ist und dessen Gewicht 200 g/m2 übersteigt. Die drei Platten 3 und 4 sind durch Leimen oder dgl. fest miteinander verbunden. The storage container (Fig. 1) has a plastic frame 1 forming the side walls, which is firmly connected to a bottom 2. The bottom 2 is cast with its edges in the frame 1 and is formed by a three-layer composite panel. Its two outer layers consist of thin sheet metal (sheet metal up to 3 millimeters). Steel or aluminum sheet with a thickness of 0.4 to 0.5 millimeters or 0.5 to 0.8 millimeters is preferably used. If the current load requirements increase significantly, thicker sheets could also be used. The middle layer 4 consists of gray, corrugated or hard cardboard (Pavatex) and the like and has a thickness of preferably 4 to 9 millimeters, 6.5 to 7.5 millimeters appearing most suitable. Although cardboard is mentioned here as the material for the middle layer 4, any plate-like material which is essentially analogous to cardboard, that is to say which is predominantly made from plant fibers by felting, gluing and pressing and whose weight exceeds 200 g / m2, is suitable. The three plates 3 and 4 are firmly connected to one another by gluing or the like.
Nach einem nicht dargestellten Ausführungsbeispiel kann der Boden 2 in Länge und Breite etwas kleiner dimensioniert sein, so dass seine Ränder lediglich auf den durch den Rahmen 1 gebildeten Auflagern 5 lose aufliegt und durch ein Anheben von unten aus dem Rahmen 1 entfernt werden kann. According to an embodiment, not shown, the bottom 2 can be dimensioned somewhat smaller in length and width, so that its edges only lie loosely on the supports 5 formed by the frame 1 and can be removed from the frame 1 by lifting from below.
Der Boden kann auch in einen handelsüblichen, unverstärkten Behälter eingelegt werden. The bottom can also be placed in a commercially available, unreinforced container.
Nach einem weiteren nicht dargestellten Ausführungsbeispiel kann die Mittelschicht aus geschäumtem Kunststoff bestehen, wobei die Schichtdicke vorzugsweise 4 bis 9 Millimeter beträgt. According to a further exemplary embodiment, which is not shown, the middle layer can consist of foamed plastic, the layer thickness preferably being 4 to 9 millimeters.
Weiter ist es möglich, den Schwerlastboden nicht nur formschlüssig auf den am Rahmen 1 angeformten Auflagern 5 zu halten, sondern gleichzeitig die Elastizität des Rahmens für eine zusätzliche, kraftschlüssige Halterung des Bodens heranzuziehen. Weiter ist es möglich, als Mittelschicht eine Holzplatte zu verwenden. It is also possible not only to hold the heavy-duty floor in a form-fitting manner on the supports 5 formed on the frame 1, but at the same time to use the elasticity of the frame for an additional, non-positive holding of the floor. It is also possible to use a wooden panel as the middle layer.
