Abstract

The method involves providing a transporter e.g. plastic pallet (1), with a support feet (3) provided at the corners of underside portion of the transporter and a groove (4) for inserting a reinforcement profile between two support feet. Force is applied to the transporter to increase the distance between the pockets (6) by elastically deforming the transporter. Profile end of the profile is placed into one of the pockets. The force is removed to cause the transporter to return to a relaxed state, where another profile end of the profile dips into other pocket and the profile is made of metal.

Description

Die Erfindung betrifft ein Verfahren zur nachträglichen Verstärkung von spritz-gegossenen Transportmitteln wie Kunststoffpaletten oder Böden von Kunststoffbehältern.The invention relates to a method for the subsequent reinforcement of injection-molded transport means such as plastic pallets or trays of plastic containers.

Da derartige Transportmittel Massenartikel sind, die in großen Stückzahlen hergestellt werden, sind schon kleinere Vereinfachungen bei der Herstellung von großem wirtschaftlichen Nutzen.Since such means of transport are mass-produced, which are produced in large quantities, even smaller simplifications in the production of great economic benefits.

Neben einer preiswerten Herstellung muss aber trotzdem eine ausreichende Stabilität der Transportmittel gewährleistet sein.In addition to a low-cost production but still sufficient stability of the means of transport must be guaranteed.

Bei unverstärkten Transportmitteln ist die Durchbiegung bei höheren Temperaturen während einer Regallagerung besonders hoch. Gerade für diesen Einsatzzweck müssen aber Möglichkeiten vorhanden sein, damit diese Durchbiegung möglichst gering gehalten werden kann.In unreinforced means of transport, the deflection at higher temperatures during a shelf storage is particularly high. Especially for this purpose but opportunities must be available so that this deflection can be kept as low as possible.

Bei einem normalen Einsatz auf einem Gabelstapler oder bei einer Fußbodenlagerung reicht allerdings die unverstärkte Ausführung der Transportmittel aus.In normal use on a forklift or floor storage, however, the unreinforced version of the means of transport is sufficient.

Der Erfindung liegt daher die Aufgabe zugrunde, Transportmittel so auszugestalten, dass sie auch nachträglich zur Verhinderung von Durchbiegungen verstärkt werden können, ohne dass Teile der fertig gegossenen Transportmittel demontiert und anschließend wieder montiert werden müssen.The invention is therefore the object of transport in such a way that they can be subsequently reinforced to prevent deflections without parts of the finished molded transport must be dismantled and then re-assembled.

Die Erfindung löst diese Aufgabe gemäß dem Patentanspruch 1 dadurch, dass auf der Unterseite der Kunststoffpalette bzw. des Behälterbodens zumindest an den Ecken Standfüße angeordnet sind und zwischen zwei diagonal sich gegenüber stehenden Standfüßen eine Nut zum Einlegen eines Verstärkungsprofils vorgesehen ist und die beiden Enden der Nut durch jeweils eine im Bereich des dem Nutende jeweils zugeordneten Standfußes dem Profilquerschnitt entsprechend geformte Taschen gebildet sind, wobei nach Fertigstellung der Palette bzw. des Behälterbodens durch elastische Verformung derselben der Abstand zwischen den beiden Taschen vergrößert wird, danach das Verstärkungsprofil in die Nut und ein Ende des Profils in eine der Taschen eingelegt wird, wonach die Verformung aufgehoben wird und die Palette bzw. der Behälterboden in den entspannten Ursprungszustand zurückkehrt und dabei auch das andere Ende des Verstärkungsprofils in die entsprechende Tasche eintaucht.The invention solves this problem according to claim 1, characterized in that are arranged on the bottom of the plastic pallet or container bottom at least at the corners feet and between two diagonally opposite feet a groove for inserting a reinforcing profile is provided and the two ends of the groove are formed by one in each case in the region of the Nutende each associated stand the profile cross-section corresponding shaped pockets, after completion of the pallet or the container bottom by elastic deformation thereof, the distance between the two pockets is increased, then the reinforcing profile in the groove and an end of the profile is inserted into one of the pockets, after which the deformation is released and the pallet or the container bottom returns to the relaxed original state and at the same time dips the other end of the reinforcing profile into the corresponding pocket.

Die Materialeigenschaften des Transportmittels ermöglichen es in gewissem Rahmen die Palette bzw. des Behälterbodens so weit zu verformen, dass das Profil eingelegt werden kann und dass nach Beendigung der Kraftausübung auf die Palette bzw. den Behälterboden diese/dieser in Folge ihrer/seiner Elastizität wieder in die Ausgangslage zurück gelangen kann.The material properties of the means of transport make it possible, to a certain extent, to deform the pallet or container bottom so that the profile can be inserted and that after completion of the application of force to the pallet or the container bottom, this / this again due to his / her elasticity the starting position can go back.

Dabei ist bevorzugt gemäß Anspruch 2 vorgesehen, dass die Palette bzw. der Behälterboden in Nutlängsrichtung gestreckt wird.It is preferably provided according to claim 2, that the pallet or the container bottom is stretched in Nutlängsrichtung.

Hierbei reichen einige Zentimeter an Verlängerung, so dass das freie Ende des Profils, also das, was dem bereits in die Tasche eingesteckten Ende entgegengesetzt ist, vor dem Eingang der Tasche zu liegen kommt. Nach der Entlastung schiebt sich die Tasche dann über dieses freie Ende des Profils. Somit ist das Profil sicher an der Unterseite (eventuell auch an der Oberseite) gehalten und gegen Herausfallen gesichert.Here are some centimeters of extension, so that the free end of the profile, that is, which is opposite to the already inserted into the bag end, comes to lie in front of the entrance of the bag. After unloading, the bag then slides over this free end of the profile. Thus, the profile is securely held on the bottom (possibly also on the top) and secured against falling out.

Andere Verformungen zur Abstandserweiterung zwischen den beiden Taschen sind möglich, beispielsweise ein Biegen der Nut um eine Achse, die senkrecht zur Nutlängsrichtung liegt.Other deformations to the distance extension between the two pockets are possible, for example, a bending of the groove about an axis which is perpendicular to the groove longitudinal direction.

Die Taschen können separat neben den Standfüßen angespritzt sein. Es ist gemäß Anspruch 4 jedoch auch denkbar, dass die Taschen in den Seitenwänden der Standfüße integriert sind.The bags can be sprayed separately next to the feet. However, it is also conceivable according to claim 4, that the pockets are integrated in the side walls of the feet.

Als Material für die Verstärkungsleisten ist beispielsweise Metall (Stahl, Aluminium etc.) vorgesehen.As a material for the reinforcing bars metal (steel, aluminum, etc.) is provided, for example.

Da Metall und Kunststoff unterschiedliche Wärmeausdehnungskoeffizienten haben, muss darauf geachtet werden, dass die Verstärkungsleiste mit Spiel in den Taschen aufgenommen ist, damit die stärkere Wärmeausdehnung des Metallprofils die Kunststoffumgebung der Palette bzw. des Behälterbodens nicht zerstört.Since metal and plastic have different thermal expansion coefficients, care must be taken that the reinforcing strip is received with play in the pockets, so that the greater thermal expansion of the metal profile does not destroy the plastic environment of the pallet or the container bottom.

Aus diesem Grunde ist es auch technisch nicht machbar, das Metallprofil gleich beim Spritzgießvorgang in die Palette bzw. den Behälterboden mit einzuspritzen.For this reason, it is technically not feasible to inject the metal profile equal to the injection molding in the pallet or the container bottom.

Die Erfindung wird im folgenden anhand von Zeichnungen dargestellt und erläutert, wobei als Ausführungsbeispiel eine Kunststoffpalette dargestellt ist.The invention is illustrated and explained below with reference to drawings, wherein a plastic pallet is shown as an exemplary embodiment.

In den Figuren ist eine Kunststoffpalette dargestellt und allgemein mit dem Bezugszeichen 1 versehen. Sie besteht aus einer Ladefläche 2, die an ihrer Unterseite wabenförmig ausgebildet ist und somit eine größere Stabilität aufweist. An den vier Ecken der Ladefläche 2 sind Standfüße 3 angeformt. Zwischen zwei diagonal sich gegenüberliegenden Standfüßen 3 ist eine Nut 4 in die wabenförmige Unterseite der Ladefläche 2 eingeformt, die an ihren Enden 5, die in unmittelbarer Nachbarschaft des jeweiligen Standfußes 3 angeordnet sind, durch Taschen 6 begrenzt ist. Die Öffnungen der Taschen weisen dabei in Nutlängsrichtung aufeinander zu.In the figures, a plastic pallet is shown and generally designated by the reference numeral 1. It consists of a loading surface 2, which is honeycomb-shaped on its underside and thus has a greater stability. At the four corners of the bed 2 feet 3 are formed. Between two diagonally opposite feet 3, a groove 4 is formed in the honeycomb underside of the loading area 2, which is bounded by pockets 6 at their ends 5, which are arranged in the immediate vicinity of the respective stand 3. The openings of the pockets have in the groove longitudinal direction to each other.

In die Nut 4 und die Taschen 6 ist eine Verstärkungsleiste 7 eingelegt. Diese Figur stellt den Endzustand der verstärkten Palette dar.In the groove 4 and the pockets 6, a reinforcing strip 7 is inserted. This figure represents the final state of the reinforced pallet.

Das Verfahren zum Einlegen der Verstärkungsleiste 7 geht aus den Figuren 2 bis 4 hervor.The method for inserting the reinforcing strip 7 goes out of the FIGS. 2 to 4 out.

In der Figur 2 ist im Schnitt die in Figur 1 dargestellte Palette 1 in Nutlängsrichtung gestreckt. Die Verstärkungsleiste 7 ist in die rechte Tasche 6 bereits eingesteckt. Das freie Ende 8 der Verstärkungsleiste 7 befindet sich oberhalb der entgegen gesetzten Tasche 6. Wie genauer aus Figur 3 hervorgeht, befindet sich dieses freie Ende 8 dabei vor der Öffnung der Tasche 6.In the FIG. 2 is on average the in FIG. 1 shown pallet 1 stretched in Nutlängsrichtung. The reinforcement strip 7 is already inserted into the right pocket 6. The free end 8 of the reinforcing strip 7 is located above the opposite pocket 6. As more accurate FIG. 3 shows this free end 8 is doing before the opening of the bag. 6

In der Figur 4 ist dann wieder der Endzustand (Figur 1) dargestellt. Hier ist die zur Verformung der Palette anzuwendende Kraft nicht mehr wirksam. Infolge ihrer Elastizität geht die Palette 1 in ihren Ursprungszustand zurück, wobei sich die Tasche 6 über das freie Ende 8 der Verstärkungsleiste 7 schiebt.In the FIG. 4 is then again the final state ( FIG. 1 ). Here, the force to be used to deform the pallet is no longer effective. As a result of their elasticity, the pallet 1 returns to its original state, with the pocket 6 sliding over the free end 8 of the reinforcing strip 7.

Wie aus dieser Figur ebenfalls hervorgeht, reicht das freie Ende 8 der Verstärkungsleiste 7 nicht ganz bis zum Boden der Tasche 6. Dieses Spiel x ist infolge verschiedener Wärmeausdehnungskoeffizienten von Verstärkungsleistenmaterial und Palettenkunststoff notwendig.As can also be seen from this figure, the free end 8 of the reinforcing strip 7 does not reach all the way to the bottom of the pocket 6.
