Description

The invention relates to a reusable plastic pallet for the transport of containers for food, in particular meat, wherein a bearing surface of the reusable pallet comprises projections distributed over its circumference and its surface.

In the food processing industry, instead of the Euro-pallets made of wood for the transport of containers for food, especially meat, returnable plastic pallets are used. To facilitate the stacking of the containers easily and safely, such reusable pallets are provided in a standardized manner. For example, the reusable pallet as a so-called. H1-pallet according to DIN 55423-5 be educated. H1 reusable pallets are for transporting so-called E-boxes according to DIN 55423-1 designed. These are specially designed for the transport of food, such as meat or fish.

A H1 Euro reusable plastic pallet is made of HDPE (high-density polyethylene) and has a usable area of 1200 mm x 800 mm at a height of 160 mm. The ground support is ensured by three runners. Four E-boxes can be placed side by side on the support surface of this pallet. Each of the four e-boxes can each be stacked again an e-box. The number of stacked E-boxes depends on the weight transported in the food containers and the dynamic load of the returnable pallet, which is 1250 kg.

The distributed over the bearing surface of the H1 reusable pallet projections ensures that each of the four, arranged on the support surface food container can not slip sideways. For this purpose, the projections on the support surface are distributed such that each a food container receiving part surface of the support surface is bounded on all sides by one or more projections.

However, when products other than dedicated e-boxes are packed on such a H1 reusable pallet, the projections may hinder easy transportation or even damage the product. This makes the use of other pallets, e.g. Euro pallets made of wood, required. However, since such other pallets are not used in the logistics of a food-processing operation, this requires additional logistics, which should be avoided if possible.

It is an object of the present invention to provide a reusable pallet, which allows in a known manner the safe transport of containers intended for food and at the same time the transport of other products without the use of these special containers.

This object is achieved by a reusable pallet according to the features of claim 1 and a depositor according to the features of claim 15. Advantageous embodiments will be apparent from the dependent claims.

According to the invention, a reusable plastic pallet is proposed for the transport of containers for foodstuffs, in particular of meat. A support surface of the reusable pallet, which is intended to receive a number of containers for food, comprises distributed over its circumference and its surface projections. The bearing surface is subdivided into a number of subplanes which are in each case planar. Each of the partial surfaces is intended to receive one of the containers. Each of the faces is bounded on each side by one or more of the projections. In addition, the reusable pallet includes one or more plate-shaped inserts. The inserts are each releasably inserted into one or more of the partial surfaces. The inserts have a thickness which corresponds at least to the height of the projections. As a result, an at least partially smooth top surface of the reusable pallet is provided.

Without the use of the depositors, the returnable plastic pallet can be used in a known manner for the transport of food containers adapted to the reusable pallet. For this purpose, each container is placed on a partial surface bounded by projections. The projections serve to prevent lateral hushing of the container placed directly on the support surface. The projections are laterally adjacent directly to respective outer walls of the containers and thereby prevent undesired lateral movement, e.g. when transporting the returnable pallet with a pallet truck or a forklift.

If other products, such as packaging materials or other containers (eg boxes), which are not adapted to the shape or dimensions of the reusable pallet or its support surface, placed on this, so a partially smooth top surface by releasably inserting a or several plate-shaped insert are provided. In this way, it is possible, for example, to transport packaging material, such as foil or paper rolls and the like, on a reusable pallet designed for the transport of food containers, without damaging the other product. After the other product has been removed from the reusable pallet provided with the inlay (s), the depositors can also be removed from the reusable Pallet be solved so that the reusable pallet can be readily used for the intended transport of adapted to the reusable pallet food containers.

Although preference is given in the present description to the transport of foodstuffs, in the containers made of a food grade plastic, such as e.g. Polyethylene or polypropylene, other products are transported.

The reusable pallet according to the invention is, in particular, a so-called H1 pallet DIN 55423-5 , The adapted to such a H1 reusable plastic pallet container for food can then called. E-boxes according to DIN 55423-1 be.

The bearing surface of the reusable pallet can consist of a total of four equal rectangular partial surfaces. As a result, as is known from the H1 reusable plastic pallet, a total of four containers adapted to the reusable pallet can be placed directly on their support surface. The four containers are arranged in a grid to two containers.

The one or more depositors are suitably made of plastic. As the plastic, for example, polyethylene, polypropylene and the like can be used.

So that the depositors have the lowest possible weight combined with high stability, they are designed in the form of hollow-chamber plates which have a honeycomb structure in cross-section. In addition to a low weight and a high stability at the same time, the inserts can be easily produced by extrusion. In this case, an infinite strand body can be produced, which in the desired length and width by a mechanical method, e.g. a punching process or a sawing process, is brought to the appropriate size and shape.

It is expedient if the depositor (s) have a closed cover surface, so that the smoothest possible cover surface of the reusable pallet is provided when the inserts are arranged on the reusable pallet.

According to a first embodiment variant, an insert can be inserted releasably into each of the partial surfaces, wherein the surface of a respective insert essentially corresponds to the surface of the partial surface of the reusable pallet. The area of a respective insert corresponds at most to the area of the associated partial area. It is preferred if the insert is slightly smaller than the extent of the partial surface in each extension direction, so that the insert does not need to be pressed in between the respectively oppositely arranged projections. This allows for easier solvability of the inserts from the reusable pallet when not in use.

In a specific embodiment, each insert has a first side edge with a length between 567 mm and 575 mm, in particular of 572 mm, and a second side edge arranged at right angles to the first side edge with a length between 370 mm and 378 mm, in particular 375 mm , on.

If an insert is releasably inserted in each of the four partial surfaces, all projections of the support surface of the returnable pallet are covered, i. all protrusions do not protrude beyond the outwardly facing top surface of the inserts. In order for a smooth in terms of the transport of objects cover surface of the reusable pallet is provided.

It is understood that not all partial surfaces may need to be covered by a depositor. Depending on whether the reusable pallet is to be loaded only on one side, it may be sufficient to insert only one, two or generally a part number of depositors in the sub-areas.

According to an alternative embodiment, an insert may be insertable into at least two or more partial surfaces. This makes it possible for a depositor to completely or only partially cover the two or more partial surfaces.

In particular, the reusable pallet may include an insert adapted to be centrally located on the support surface relative to a side edge of the reusable pallet and extending in a longitudinal direction of the reusable pallet with respect to the other side edge of the reusable pallet. This makes it possible, for example, with the help of such a reusable pallet foil and paper rolls and cardboard to transport, which rest only in a narrow central area of the reusable pallet. For the transport of such products, it is sufficient to place only a single depositor on or in the returnable pallet. This makes the handling of the reusable pallet according to the invention very simple. With such an insert, in particular projections located only in a central axis of the reusable pallet are covered so that the desired smooth top surface is provided in this central region.

The insert may have a length which is the length of the reusable pallet in the longitudinal direction equivalent. As a result, films and paper rolls can be transported, which claim the total length of the reusable pallet or even protrude beyond this. Conveniently, the length of the insert is between 900 mm and 1200 mm.

The width of the insert is according to an expedient embodiment between 80 mm and 250 mm, in particular 150 mm. The width may also be slightly larger, e.g. 200 mm, or smaller, e.g. 120 mm, be. As a result, even with film and paper rolls, which have a diameter in the width of the reusable pallet, ensures that the product rests on a smooth top surface.

To provide the smooth top surface, the insert may have recesses in each of which protrude one or more projections of the reusable pallet. The insert has a thickness which corresponds at least to the height of the projections, so that the desired smooth cover surface is achieved. From the point of view of a "smooth top surface", it is desirable if the projections lie in one plane with the top surface facing away from the reusable pallet. Since the projections should in no case project beyond the plane of the top surface, it is expedient for the consideration of manufacturing tolerances to choose the thickness of the insert slightly larger than the height of the projections.

There is further proposed an insert for a reusable pallet of the type described above, which has a right-shaped plate-shaped body whose opposite top surfaces are closed. In this case, the cover surfaces are connected to one another via webs, which form a honeycomb structure in the cross section of the insert. The top surfaces and inserts are made in one piece from a plastic. As a plastic, for example, polypropylene or polyethylene can be used. The dynamic load of the insert is at least 1000 kg. The lengths of the side edges are adapted to the dimensions of one or more faces and / or protrusions of the reusable pallet.

The inventions proposed insert is easy to manufacture and easy to handle. Due to the design as a hollow chamber plate, it is lightweight and has a high stability. The fact that the top surfaces are closed, a smooth support surface is provided so that no punctual loads for the products lying on it. The inserts can be provided as accessories for a returnable plastic pallet to compensate for protrusions formed on the support surface thereof. If the partial surfaces are covered by adapted inserts, a smooth top surface is created, which is desirable for the transport of some products.

In a first embodiment variant, the insert has a first side edge with a length between 567 mm and 575 mm, in particular 572 mm, and a second side edge arranged at right angles to the first side edge with a length between 370 mm and 378 mm, in particular 375 mm , on. This insert expediently has no recess.

According to another embodiment, the insert has a first side edge with a length between 900 mm and 1200 mm, and a second, perpendicular to the first side edge arranged side edge with a length between 80 mm and 250 mm, in particular of 150 mm. The insert has a number of recesses, in particular four, which are distributed centrally with respect to the second side edge and equidistantly with respect to the first side edge.

The dimensions of the recesses and the distance between two recesses are adapted to the dimensions and arrangement of the projections of the reusable pallet.

The height of the insert is preferably between 7 mm and 8 mm. It is ensured that after inserting the insert into a respective partial surface or generally on the support surface of the reusable pallet, the protrusions thereon are covered, i. lie approximately in a plane with the facing away from the reusable pallet top surface.

The invention will be explained in more detail below with reference to exemplary embodiments in the drawing.
