Description

Die Erfindung betrifft einen Transport- und/oder Lagerbehälter, der einen rechteckigen oder quadratischen Grundriß mit verrundeten Ecken aufweist, - mit einem Innenbehälter, der im Wege der Blasformgebung aus Kunststoff geformt ist, und mit einem Außenbehälter, der einen Außenbehältermantel und einen Außenbehälterboden aufweist, wobei der Außenbehältermantel aus umlaufenden und vertikalen Rundstahlstäben besteht, die miteinander verschweißt sind, wobei die vertikalen Rundstahlstäbe mit ihren unteren und oberen Enden mit einem behältermantelaußenseitig angeschweißten Abschlußrahmen aus Rundstahl verbunden sind.The invention relates to a transport and / or storage container which has a rectangular or square outline with rounded corners, with an inner container which is molded from plastic by means of blow molding, and with an outer container which has an outer container jacket and an outer container bottom, wherein the outer container jacket consists of circumferential and vertical round steel rods which are welded to one another, the vertical round steel rods being connected at their lower and upper ends to an end frame made of round steel welded to the outside of the container jacket.

Transport- und/oder Lagerbehälter des vorstehend beschriebenen Aufbaues sind in verschiedenen Ausführungsformen bekannt. Bei der Ausführungsform, von der die Erfindung ausgeht (DE-A-90 00 453), ist der Außenbehälterboden als Holzpalette ausgeführt. Palette bezeichnet dabei die bekannten Einrichtungen für die moderne Handhabung von Gütern mit Hilfe von Gabelstaplern u. dgl., wobei die Palette die Güter aufnimmt und das Einfahren der Arme eines Gabelstaplers o. dgl. zuläßt. Bei dem bekannten Transport- und/oder Lagerbehälter ist der Außenbehältermantel an die Palette angeschlossen und der Innenbehälter in den Außenbehältermantel eingesetzt. Die bekannten Transport- und/oder Lagerbehälter des eingangs beschriebenen Aufbaues mit Holzpaletten haben sich bewährt. Die sichere Befestigung des Außenbehältermantels an der Außenpalette so, daß auch erhebliche Transportbeanspruchungen aufgenommen werden, ist jedoch aufwendig und muß weitgehend manuell durchgeführt werden. Bei auslegungsüberschreitenden Beanspruchungen des Transport- und/oder Lagerbehälters, z. B. bei Absturz des Transport- und/oder Lagerbehälters aus einem Hebezeug, geht die Holzpalette zu Bruch. Bei einer anderen Ausführungsform (EP-A-0 367 946) ist auch der Außenbehälterboden aus Rundstahlstäben geformt, die von den vertikalen Rundstahlstäben des Außenbehältermantels abgebogen sind. So bildet der Außenbehältermantel und der Außenbehälterboden in vorteilhafter Weise ein einheitliches Bauteil. Palettenfüße aus Rundstahlstäben sind angeformt oder als zusätzliche Bauteile angeschweißt. Bei einem so aufgebauten Transport- und/oder Lagerbehälter ist der Außenbehälter einschließlich des Außenbehälterbodens in bezug auf auslegungsüberschreitende Beanspruchungen haltbarer als bei der Ausführungsform mit Holzpalette. Diese bekannte Ausführungsform zeichnet sich daher durch große Lebensdauer aus. Die Dauerfestigkeit gegenüber Beanspruchungen, die beim Transport über weite Strecken aus unvermeidbaren Schwingungen entstehen können, ist jedoch verbesserungsfähig.Transport and / or storage containers of the structure described above are known in various embodiments. In the embodiment from which the invention is based (DE-A-90 00 453), the outer container bottom is designed as a wooden pallet. Pallet designates the known facilities for the modern handling of goods with the help of forklifts u. Like., The pallet receives the goods and allows the retraction of the arms of a forklift or the like. In the known transport and / or storage container, the outer container shell is connected to the pallet and the inner container is inserted into the outer container shell. The known transport and / or storage containers of the construction described above with wooden pallets have proven themselves. The secure attachment of the outer container shell to the outer pallet so that considerable transport stresses are absorbed, however, is complex and has to be carried out largely manually. In the case of stresses beyond design the transport and / or storage container, e.g. B. if the transport and / or storage container falls from a hoist, the wooden pallet breaks. In another embodiment (EP-A-0 367 946), the outer container base is also formed from round steel rods which are bent off from the vertical round steel rods of the outer container shell. The outer container jacket and the outer container base thus advantageously form a single component. Pallet feet made of round steel bars are molded or welded on as additional components. With a transport and / or storage container constructed in this way, the outer container, including the outer container base, is more durable with respect to stresses beyond the design than in the embodiment with a wooden pallet. This known embodiment is therefore characterized by a long service life. However, there is room for improvement in the fatigue strength against stresses that can arise from unavoidable vibrations during long-distance transport.

Der Erfindung liegt die Aufgabe zugrunde, einen Transport- und/oder Lagerbehälter zu schaffen, der sich durch hohe Lebensdauer und große Dauerfestigkeit auszeichnet, nichtsdestoweniger jedoch einfach und weitgehend automatisch zu fertigen ist.The invention has for its object to provide a transport and / or storage container, which is characterized by long life and great fatigue strength, but is nevertheless simple and largely automatic to manufacture.

Zur Lösung dieser Aufgabe ist Gegenstand der Erfindung ein Transport- und/oder Lagerbehälter, der einen rechteckigen oder quadratischen Grundriß mit verrundeten Ecken aufweist, - mit einem Innenbehälter, der im Wege der Blasformgebung aus Kunststoff geformt ist, und mit einem Außenbehälter, der einen Außenbehältermantel sowie einen Außenbehälterboden aufweist, wobei der Außenbehältermantel aus umlaufenden und vertikalen Rundstahlstäben besteht, die miteinander verschweißt sind, und wobei die vertikalen Rundstahlstäbe mit ihren unteren und oberen Enden mit einem behältermantelaußenseitig angeschweißten Abschlußrahmen aus Rundstahl verbunden sind, und wobei der Außenbehälterboden als Stahlblechpalette mit einer oberen Stahlblechplatte ausgeführt ist, welche obere Stahlblechplatte im Querschnitt liegend U-förmige Umbiegungen aufweist, die den unteren Abschlußrahmen von außen umfassen. Zweckmäßigerweise weist die obere Stahlblechplatte an zumindest zwei gegenüberliegenden Seiten die Umbiegungen auf. Nach bevorzugter Ausführungsform ist die obere Stahlblechplatte an zwei gegenüberliegenden Seiten und an einer diese Seiten verbindenden Stirnseite mit den Umbiegungen versehen. Wie weiter unten erläutert wird, wird die Fertigung besonders einfach, wenn die obere Stahlblechplatte an der umbiegungsfreien Seite bzw. an den umbiegungsfreien Seiten Überfassungszungen aufweist, die den unteren Abschlußrahmen von innen überfassen.To achieve this object, the object of the invention is a transport and / or storage container, which has a rectangular or square plan with rounded corners, - with an inner container, which is formed by blow molding from plastic, and with an outer container, the outer container shell and has an outer container bottom, wherein the outer container jacket circumferential and vertical round steel bars are welded to each other, and the vertical round steel bars are connected with their lower and upper ends to a tank frame outer side welded end frame made of round steel, and wherein the outer container bottom is designed as a steel plate pallet with an upper steel plate plate, the upper steel plate plate in cross section lying U-shaped bends that surround the lower end frame from the outside. The upper sheet steel plate expediently has the bends on at least two opposite sides. According to a preferred embodiment, the upper sheet steel plate is provided with the bends on two opposite sides and on an end face connecting these sides. As will be explained further below, production becomes particularly simple if the upper steel sheet plate has covering tongues on the non-bending side or on the non-bending sides, which cover the lower end frame from the inside.

Bei dem erfindungsgemäßen Transport- und/oder Lagerbehälter sind im allgemeinen an die obere Stahlblechplatte nach unten hin Palettenfüße aus Stahlblech angeschweißt, die Einschubwege für Gabelstaplerarme zwischen sich freilassen. Die Palettenfüße können an eine untere Stahlblechplatte oder an Stahlblechzuschnitte angeschlossen sein. Im Bereich der Ecken der Paletten können der Verrundung entsprechende, von einer der Blechplatten abgebogene oder angeschweißte Blechteile angeordnet sein, die stabilisierend und die Gestaltfestigkeit erhöhend wirken. Damit die erfindungsgemäßen Transport- und/oder Lagerbehälter, wenn sie geometrisch gleich gestaltet sind, ihrerseits gestapelt werden können, empfiehlt sich eine Ausführungsform, bei der die Stahlblechpalette eine untere Absetzung aufweist, die beim Stapeln der Transport- und/oder Lagerbehälter in den oberen Abschlußrahmen des Außenbehältermantels mit den angeschweißten vertikalen Rundstahlstäben einfaßt. Die Stahlblechplatte kann ebenso wie der Boden des Innenbehälters auslauffördernd gestaltet sein, so daß eine in den Innenbehälter eingefüllte Flüssigkeit dem Auslauf zuläuft, der sich im tiefsten Teil im Bereich des Innenbehälterbodens befindet. Dieser kann mit zunehmender Entleerung auffedern, was das Auslaufen verbessert und unterstützt.In the case of the transport and / or storage container according to the invention, pallet feet made of sheet steel are generally welded downward to the upper steel sheet plate, leaving the insertion paths for forklift arms between them. The pallet feet can be connected to a lower sheet steel plate or to sheet steel blanks. In the area of the corners of the pallets, the rounding corresponding sheet metal parts bent or welded on by one of the sheet metal plates can be arranged, which have a stabilizing effect and increase the structural strength. So that the transport and / or storage containers according to the invention, if they are geometrically identical, can in turn be stacked, An embodiment is recommended in which the sheet steel pallet has a lower shoulder which, when the transport and / or storage containers are stacked, surrounds the upper end frame of the outer container shell with the welded-on vertical round steel rods. The sheet steel plate, like the bottom of the inner container, can be designed to promote leakage, so that a liquid filled into the inner container flows to the outlet, which is located in the deepest part in the area of the inner container bottom. This can spring open with increasing emptying, which improves and supports the leakage.

Die Erfindung nutzt zunächst die Tatsache, daß Stahlblechpaletten, die in anderer Ausführungsform an sich und für sich bekannt sind, eine größere Lebensdauer aufweisen, als Holzpaletten. Die Erfindung geht ferner von der Erkenntnis aus, daß der Behälteraußenmantel an eine solche Stahlblechpalette ohne die Gefahr der Ausbildung dauerbruchgefährdeter Verbindungsstellen angeschlossen werden kann, wenn die Stahlblechpalette eine obere Stahlblechplatte aufweist, die wie beschrieben mit im Querschnitt liegend U-förmigen Umbiegungen versehen ist, die den unteren Abschlußrahmen von außen umfassen. Auf diese Weise werden schweißtechnische Verbindungen, die häufig dauerbruchgefährdet sind, vermieden. Das schließt nicht aus, zusätzlich gleichsam sichernde Schweißverbindungen zwischen dem Außenbehältermantel und der Stahlblechpalette durchzuführen.The invention first makes use of the fact that steel sheet pallets, which are known per se and in another embodiment, have a longer service life than wooden pallets. The invention is also based on the knowledge that the container outer jacket can be connected to such a sheet steel pallet without the risk of the formation of joints at risk of breakage if the sheet steel pallet has an upper sheet steel plate which, as described, is provided with U-shaped bends lying in cross section, which enclose the lower end frame from the outside. In this way, welding connections that are often at risk of fatigue failure are avoided. This does not preclude additionally performing, as it were, secure weld connections between the outer container jacket and the sheet steel pallet.

Zu einer besonders großen Dauerfestigkeit kommt man, wenn die Stahlblechpalette schwingungsarm ausgelegt ist. Darunter wird verstanden, daß die Stahlblechpalette unter Beachtung der Gesetze der Schwingungslehre so gestaltet ist, daß in dem Frequenzbereich, in dem der Transport- und/oder Lagerbehälter beim Transport Erschütterungen erfährt, keine Eigenschwingungen liegen. Die Stahlblechpalette wird zweckmäßigerweise so gestaltet, daß die Eigenschwingungen in dem Bereich extrem hoher Frequenzen verschoben sind. Dazu kann zumindest die obere Stahlblechplatte der Stahlblechpalette schwingungshemmende Versteifungsprofilierungen aufweisen. Die schwingungshemmenden Versteifungsprofilierungen sind nach bevorzugter Ausführungsform randseitig umlaufend und diagonal angeordnet. Schwingungshemmend meint im Rahmen der Erfindung, daß Eigenschwingungen im niedrigen Frequenzbereich unterdrück sind.A particularly high fatigue strength is achieved if the steel sheet pallet is designed to be low-vibration. This means that the sheet steel pallet is designed in compliance with the laws of vibration theory so that in the frequency range in which the transport and / or Storage container experiences vibrations during transport, there are no natural vibrations. The steel sheet pallet is expediently designed so that the natural vibrations are shifted in the area of extremely high frequencies. For this purpose, at least the upper steel sheet plate of the steel sheet pallet can have anti-vibration stiffening profiles. According to a preferred embodiment, the anti-vibration stiffening profiles are circumferential and diagonally arranged. Vibration-inhibiting means in the context of the invention that natural vibrations in the low frequency range are suppressed.

Ein erfindungsgemäßer Transport- und/oder Lagerbehälter kann auf sehr einfache Weise hergestellt werden. In diesem Zusammenhang ist Gegenstand der Erfindung ein Verfahren zur Herstellung des Außenbehälters für einen Transport- und/oder Lagerbehälter, wobei der Außenbehältermantel und die Stahlblechpalette unabhängig voneinander hergestellt werden, und zwar die Stahlblechpalette mit angeformten, im Querschnitt liegend U-förmigen Umbiegungen an zumindest zwei gegenüberliegenden Seiten und Überfassungszungen, wobei der Außenbehältermantel mit zwei gegenüberliegenden Seiten des unteren Abschlußrahmens in die gegenüberliegenden, im Querschnitt liegend U-förmigen Umbiegungen der Stahlblechpalette eingeschoben wird, und wobei danach die Überfassungszungen über den unteren Abschlußrahmen gebogen werden. Vorzugsweise wird die Stahlblechpalette dabei an drei Seiten der oberen Stahlblechplatte mit dem im Querschnitt liegend U-förmigen Umbiegungen versehen und wird der untere Abschlußrahmen in diese Umbiegungen mit zwei gegenüberliegenden Seiten und einer Stirnseite eingeschoben. - Sowohl der separat hergestellte Außenbehältermantel als auch die Stahlblechpalette können weitgehend automatisch gefertigt werden. Aber auch die Verbindung durch das beschriebene Ineinanderschieben läßt sich auf einfache Weise und im Bedarfsfall weitgehend automatisch verwirklichen.A transport and / or storage container according to the invention can be produced in a very simple manner. In this context, the invention relates to a method for producing the outer container for a transport and / or storage container, the outer container shell and the steel sheet pallet being produced independently of one another, specifically the steel sheet pallet with integrally formed, cross-sectionally U-shaped bends on at least two opposite sides and cover tongues, wherein the outer container casing is inserted with two opposite sides of the lower end frame into the opposite, cross-sectionally U-shaped bends of the steel sheet pallet, and the cover tongues are then bent over the lower end frame. The sheet steel pallet is preferably provided on three sides of the upper sheet steel plate with the U-shaped bends lying in cross section, and the lower end frame is inserted into these bends with two opposite sides and one end face. - Both the separately manufactured outer container casing and the sheet steel pallet can largely be manufactured automatically become. But also the connection through the described pushing together can be realized largely automatically in a simple manner and if necessary.

Der in den Figuren dargestellte Transport- und/oder Lagerbehälter besitzt einen im Ausführungsbeispiel rechteckigen Grundriß mit verrundeten Ecken. Er könnte auch einen quadratischen Grundriß aufweisen, wozu insbesondere auf die Fig. 2 verwiesen wird. Zum grundsätzlichen Aufbau gehören ein Innenbehälter 1, der im Wege der Blasformgebung aus Kunststoff geformt ist, und ein Außenbehälter 2, der einen Außenbehältermantel 3 und einen Außenbehälterboden aufweist. In den Fig. 2 bis 7 wurde der Innenbehälter weggelassen.The transport and / or storage container shown in the figures has a rectangular outline with rounded corners in the exemplary embodiment. He could also be one have square plan, for which reference is made in particular to FIG. 2. The basic structure includes an inner container 1, which is formed by blow molding from plastic, and an outer container 2, which has an outer container shell 3 and an outer container bottom. 2 to 7, the inner container has been omitted.

Man entnimmt aus einer vergleichenden Betrachtung der Figuren, daß der Außenbehältermantel 3 aus umlaufenden und vertikalen Rundstahlstäben 4 bis 5 besteht, die miteinander verschweißt sind. Die vertikalen Rundstahlstäbe 4 sind mit ihren unteren und oberen Enden mit einem behältermantelaußenseitig aufgeschweißten Abschlußrahmen 6 aus Rundstahl verbunden.It can be seen from a comparative examination of the figures that the outer container casing 3 consists of circumferential and vertical round steel bars 4 to 5 which are welded together. The vertical round steel bars 4 are connected with their lower and upper ends to a container frame-welded end frame 6 made of round steel.

Der Außenbehälterboden ist als eine Stahlblechpalette 7 mit einer oberen Stahlblechplatte 8 ausgeführt. Die obere Stahlblechplatte 8 besitzt im Querschnitt liegend U-förmige Umbiegungen 9, die den unteren Abschlußrahmen 6 von außen umfassen. Dazu wird insbes. auf die Fig. 1 sowie 3 und 5 verwiesen. Im Ausführungsbeispiel ist die Anordnung so getroffen, daß die obere Stahlblechplatte 8 an zwei gegenüberliegenden Seiten die Umbiegungen 9 aufweist, wobei aber eine Umbiegung 9 außerdem an einer diese Seiten verbindenden Stirnseite angeordnet sind. Man erkennt insbes. aus einer vergleichenden Betrachtung der Fig. 1 und 4, daß die obere Stahlblechplatte 8 an der umbiegungsfreien Seite Überfassungszungen 10 aufweist, die den unteren Abschlußrahmen 6 von innen überfassen. An die obere Stahlblechplatte 8 sind nach unten hin Palettenfüße 11 aus Stahlblech angeschweißt. Sie lassen Einschubwege 12 für Gabelstaplerarme zwischen sich frei. Die Palettenfüße 11 sind ihrerseits an eine untere Stahlblechplatte 13 oder an Stahlblechzuschnitte angeschlossen, nämlich ebenfalls angeschweißt. Das kann im Rahmen einer automatischen Fertigung geschehen. Man erkennt insbes. in den Fig. 6 und 7, daß die Stahlblechpalette 7 eine untere Absetzung 14 aufweist, die beim Stapeln der Transport- und/oder Lagerbehälter in den oberen Abschlußrahmen 6 des Behältermantels 3 mit den angeschweißten vertikalen Rundstäben 4 einfaßt.The outer container bottom is designed as a sheet steel pallet 7 with an upper sheet steel plate 8. The upper sheet steel plate 8 has lying in cross section U-shaped bends 9 which surround the lower end frame 6 from the outside. For this purpose, reference is made in particular to FIGS. 1 and 3 and 5. In the embodiment, the arrangement is such that the upper steel plate 8 has the bends 9 on two opposite sides, but a bend 9 is also arranged on an end face connecting these sides.
