Definitions
- the present invention relates to a stackable transport pallet made of plastic.
- Transport pallets are usually in standardized dimensions, e.g. Made in the so-called Euro pallet size 1000 mm x 1200 mm or in the dimension 800 mm x 1200 mm and are often made of wood.
- such wooden pallets have a relatively high weight and - based on their own weight - a low load capacity.
- the weather resistance in outdoor storage is problematic because wood absorbs moisture, which can lead to mold and rot.
- the stack height of wooden pallets is limited.
- the invention has for its object to provide a stackable plastic pallet, which is inexpensive to manufacture and can accommodate high payloads with low weight.
- the use of recycled plastics is provided with the addition of organic fibers, preferably with the addition of organic cellulose fibers.
- a kind of micro-reinforcement of the plastic is created by the tensile and flexural strength and thus the stability of the material is significantly improved or is.
- Zellulosef fibers or in addition to cellulose fibers and hemp fibers can be used.
- Suitable recycled plastics are, for example, mixtures of polyethylene and / or polypropylene and / or polycarbonates which have an impurity content of not more than 10% (volume fraction). Such plastics are available in Germany by the so-called packaging recycling in large quantities.
- the cellulose fibers used preferably have an average fiber length in the range of 0.5 to 3 mm, preferably 1 to 2 mm, particularly preferably about 1.4 mm.
- the mean diameter is in the range of 10 to 100 microns, preferably about 60 microns. This results in a typical fiber tensile strength of at least about 1 N / mm 2 .
- the volume fraction of fibers is between 3% and 50%, preferably between 10% and 20%, more preferably about 15% (ie 15% fibers and 85% plastic mixture).
- the exact amount used depends on the quality of the recycled plastic mixture and the requirements on the payloads.
- the stability of the plastic material tends to increase as the proportion of cellulose fibers increases.
- the solution of the object according to the invention can also be achieved by the special design of the pallet according to the invention. According to the invention, by means of these ormgestalterischen aspects, the object underlying the invention can be achieved, even regardless of the specific choice of material for the plastic from which the pallet is made.
- Fig. 1 is a perspective view of the top of a plastic pallet according to the invention
- Fig. 2 is a perspective view of the underside of a plastic pallet according to the invention.
- FIG. 3 is a sectional view, not to scale, of the teardrop-shaped edge of a plastic pallet according to the invention.
- Figures 4 and 5 are cross-sectional views of the feet of a plastic pallet according to the invention.
- an embodiment of a plastic pallet according to the invention has a rectangular shape (preferred dimensions: width 1000 mm, length 1200 mm or width 800 mm, length 1200 mm) with a longitudinal and a shorter side opposite the long side broadside.
- the top of the pallet forms a flat support surface 1 for the palletizing material to be stacked or transported.
- the pallet is supported by a total of nine hollow feet 2 which are made integrally from the plastic material of the cartridge. lette are formed and the support surface 1 each form an opening 13.
- the feet are grid-like arranged in three rows, with eight feet each at the edge of the pallet (four of them at the corners) and a base 18 are arranged centrally. Characterized in that the feet 2 are hollow and open towards the support surface 1, the pallets can be stacked, the entire stack height is reduced by the insertable into the openings 13 of an adjacent pallet feet 2 and the stability of the stack formed is increased. In the marginal gaps between the feet 2, a fork of a material handling vehicle retract or intervene on all sides, whereby the Kunststoffsto fpalette transported with load or can be separated from other pallets of a stack.
- the feet 2 have a rectangular shape, wherein the longer side is oriented in each case parallel to the longitudinal side of the plastic pallet.
- the feet 2 are also conically tapered downwards, so that center themselves in the pallets during a stacking process.
- the reinforcing ribs 4 on the broad side have a larger volume than the reinforcing ribs 8 on the longitudinal side.
- the respective middle feet of the respective sides are connected to the central base 18 via two ribs 12 arranged like a cross.
- two reinforcing ribs 9 are further provided between the feet.
- the pallet surface also has a symmetrical hole pattern 10.
- the transport pallet according to the invention can be produced very economically by extrusion of a corresponding material mixture at temperatures of 160 to 180 ° C in a closed form dockable to the extruder.
- static load capacities typically 4000 kg and dynamic load capacities of about 1500 kg can be realized.
- the range is very simple and very inexpensive to manufacture and easily reusable.
- the pallet has - based on its carrying capacity - a low empty weight and can be used in a wide temperature range of -40 to 120 ° C.
- the plastic surfaces used are hygienic and easy to clean, even in humid environments.
- At least the tops of the transport pallet preferably have a he heightened surface roughness.
- at the edges of the transport pallet can be formed by a few millimeters protruding edge (not shown in the drawings), which forms a stop for the resting Pallettiergut.
- Such a stop need not be formed continuously along the entire circumference of the pallet, but may also be recessed, for example, in the region of the most vulnerable to damage corners.
- load-bearing runners can be attached to increase the carrying capacity as needed on the underside of the pallet.
- These skids can be clipped by means of pins in the outlet openings 15 of the feet, with the strips parallel to the longer side of the extend rectangular feet and connect the rows of feet each with each other.
- the preparation of the pallet according to the invention is preferably carried out by extrusion of the described material mixture.
- the extrusion is preferably carried out at 160 to 180 ° C in a closed, attachable to the extruder aluminum mold.
- the material mixture is portioned into the extruder, liquefied by heating creamy and pressed through the screw conveyor of the extruder into the aluminum mold.
- the material can be compacted in the mold accordingly.
- the mold is then removed from the extruder and cooled with water for curing.
