Definitions

  • the present invention relates to a transport pallet usable in particular for the handling of goods.
  • such a pallet is made of wood and generally comprises support boards, on which the goods are intended to rest.
  • the support planks are parallel to each other and are kept spaced from plinth planks, also parallel to each other and to the support planks, by means of three transverse bracing elements which are fixed by nailing in the middle part and at the ends of the planks. support and plinth boards to connect them.
  • the bracing elements usually comprise three solid blocks joined by upper and lower rails to which the support boards and the plinth boards are respectively fixed.
  • a disadvantage of these pallets is that they have a large number of elements (twenty-four for the most common pallet constitution, namely six support boards, three upper rails, nine pads, three lower rails and three planks ), which implies relatively high assembly, labor and inventory management costs. The manufacturing time is also relatively long.
  • wooden pallets are relatively fragile and need to be repaired regularly.
  • wood pallets have the disadvantage of loading moisture, which increases their mass.
  • the moisture tends to go up to the support boards and eventually reach the goods stored on the pallet.
  • An object of the invention is to provide a robust and simple constitution palette.
  • the subject of the invention is a transport pallet comprising parallel support elements having at least end portions fixed by means of assembly to transverse connecting elements which comprise a beam of C-shaped cross-section having an upper wing on which the support elements, a web and a lower wing (see US-A-3 602 157), are fixed, characterized in that the web and the lower wing are recessed by at least an indentation to form on each side thereof two brackets spaced apart and in one piece with the transverse element.
  • the pallet constituted in this way can easily be achieved by assembling the various elements and have properties of the same order as those of conventional pallets and in particular those of wood, or even greater than those of pallets made of injected thermoplastic material of the current type.
  • the C-shaped profile of the beam thus allows a good distribution of the weight supported by the pallet.
  • this beam has a good structural strength due to its structure, which makes it possible in particular with respect to conventional wooden pallets, to overcome the use of a lower crossbar joining the brackets and thus to reduce the height of the palette.
  • transverse beams can also be made of materials that do not absorb moisture and thus prevent it from rising to the goods supported by the pallet.
  • the pallet comprises at least one stiffening element extending parallel to the support members at a distance therefrom between two opposite brackets, the stiffening element being formed by a plank-shaped beam, the lower surface of said beam being grooved and the latter comprising at least one chamfer arranged on at least one of its upper longitudinal edges.
  • the pallet is thus particularly resistant. This also allows on the one hand to lighten the pallet and on the other hand to limit the risk of a shock between the stiffening element and the end of the forks.
  • the transverse beam comprises at one of the brackets, at least one reinforcing rib extending on the web between the upper and lower wings.
  • the transverse beam then has an increased resistance to shocks that may cause the fork of the forklifts of the handling trucks on the web of the transverse beam.
  • At least the transverse beams are made of a thermoplastic material.
  • virgin polyethylene terephthalate is a material frequently used in the manufacture of widely diffused products such as bottles or consumer goods.
  • Recycled polyethylene terephthalate in particular that from household waste, often has a heterogeneous character and physicochemical characteristics of relatively low level that limit its use as a recycled product to the manufacture of thin and poor quality parts, in the material of which it is incorporated in small quantities.
  • the recycling of all polyethylene terephthalate product is currently practically impossible. This is amplified by the fact that the recycled polyethylene terephthalate, just like the virgin polyethylene terephthalate of current quality, can not be used for the production of massive pieces. As a result, the amount of polyethylene terephthalate that can be recycled into products is limited.
  • This piece has satisfactory mechanical characteristics which, in the preferred composition, are similar to those of the wood particularly with regard to the breaking strength and gives the parts made of this material assembly possibilities similar to those of wood.
  • the pallet according to the invention comprises support elements 10 in the form of planks having a rough upper surface 11.
  • the support members 10 are attached at their opposite ends 12, 13 and their middle portion 14 to transverse link beams.
  • the connecting beams 20 are of C cross-section and have an upper wing 21 and a lower wing 22 connected by a web 23.
  • the support elements 10 are fixed on the upper wing 21.
  • each connecting section three brackets generally designated 25 and connected by the upper flange 21. It will be noted here that each recess 24 is formed in a lower portion of the core 23 so that a remaining portion of the core 23 extends above the recess between the brackets. Other arrangements of the recesses are possible.
  • Reinforcing ribs 26 extend at each bracket 25 on the web 23 between the upper wing 21 and the lower wing 22 to improve the resistance of the brackets, in particular to impacts received on the web 23.
  • the facing lower flange portions 22 belonging to the three connecting beams are connected by three stiffening elements 30 which extend parallel to the support elements 10.
  • the stiffening elements 30 are board-shaped and have a lower surface 31 having longitudinal grooves 32 and an upper surface 33 on which are fixed the lower flanges 22 of the connecting pieces 20.
  • the upper longitudinal edges 34 of the stiffening elements 30 are chamfered.
  • the ends of the forks of the industrial trucks are generally beveled in their lower part so that by cooperating with these bevelled parts, the chamfers form ramps guiding the ends of the forks above the elements 30. The risk of a collision between these elements 30 and the forks is thus limited. This also makes it possible to lighten these stiffening elements.
  • the assembly of the various elements constituting the pallet is achieved by screwing, nailing, gluing or welding or by combining these means.
  • the pallet or at least some elements thereof are assembled by nailing.
  • the reinforcing rib 26 advantageously then has a cross section of dimensions greater than those of the cross section of at least one nail 27 so that the nail can be stuck in the reinforcing rib 26.
  • the reinforcing rib 26 then ensures a dual function, namely a reinforcement function of the bracket and a receiving function of the nail 27.
  • the cross section of the reinforcing rib 26 allows it to accommodate three nails 27 stuck in the reinforcing rib 26 and for example in one of the support boards 10 and in the upper flange 21 to serve for the attachment of the support board 10 on the bracket 25.
  • Another means of receiving nails by plugging is to provide a local extra thickness of the upper flange 21 at the brackets 25 to allow the plugging of the fastening nails of the support boards 10.
  • the pallet is intended to rest on the ground by the stiffening elements 30 which form a base and is intended to support the goods by the support elements 10 which form a tray on which the goods can rest.
  • the connecting beams 20 hold together the elements 10 and 30 and provide a space between them for the passage of the forks of a handling truck.
  • the invention applies to any type of pallet including pallets without stiffening elements or pallets in which the support elements are replaced by a single plate.
  • high density polyethylene makes it possible to obtain a material which is of greater amorphous character than if only polyethylene terephthalate (which is very crystalline) was used. This improves the mechanical strength of the material obtained.
  • the compatibilizing agent is, for example, that referenced LOTADER AX8900 from the company ELF ATOCHEM which is used to ensure the homogenization of the mixture of recycled polyethylene terephthalate and recycled high-density polyethylene.
  • Other compatibilizing agents having comparable properties can of course be used.
  • the reinforcing filler used may be formed of glass fibers such as those produced under the reference 3540 by the company PPG. These fibers, which have a length of 3 mm, improve Young's modulus and impact resistance.
  • the reinforcing filler may also be formed of glass flakes of the type produced under the reference MICROGLAS by the company NGF EUROPE. These scales make it possible to obtain an increase in the Young's modulus and an increase in elongation which is accompanied by an increase in the impact resistance.
  • the use of glass flakes makes it possible to limit the increase in the viscosity of the mixture due to the introduction of said flakes into it with respect to the introduction of fibers.
  • the scales are more likely on the one hand to influence the crystallinity and on the other hand an influence on the shrinkage as they limit the formation of microcracks.
  • reinforcing fillers can be used alone or in combination, for example glass microbeads. A mixture of glass fibers and glass flakes is thus usable.
  • emulsifier such as zinc carbonate can be used. This creates bubbles in the material and reduces the mass of profiles made with it. Pigments can also be added to color the material.
  • the profiles 10, 20, 30 are made by extrusion-molding or extrusion-intrusion.
  • the recycled polyethylene terephthalate and the recycled high-density polyethylene used are preferably in the form of flakes obtained by grinding polyethylene terephthalate waste and high-density polyethylene waste and washing the flakes obtained. Granules of these materials could also be used, but this requires additional operations (mixing the flakes of each material with fillers, extruding these mixtures, cooling and then grinding into granules).
  • the flakes of polyethylene terephthalate are firstly dried, for example in a desiccator, in order to prevent hydrolysis of the polyethylene terephthalate occurring during the subsequent extrusion thereof. It has been found that such hydrolysis directly causes a decrease in the impact resistance of polyethylene terephthalate. High density polyethylene can also be dried.
  • the flakes of polyethylene terephthalate and high density polyethylene, the compatibilizing agent and the reinforcing fillers are then mixed and introduced into the feed hopper of an extruder. It is important to ensure that the flakes are lowered into the hopper.
  • the temperature of the heating body of the extruder is here of the order of 250 ° on the side of the hopper and 275 ° on the output side of the extruder.
  • the residence time thereof in the extruder is preferably between one and a few minutes.
  • the residence time of the material in the extruder is determined in particular by the length of the screw of the extruder, the pitch thereof and its rotational speed.
  • a pasty mixture is obtained which is directly introduced into a mold whose shape corresponds to the beam to be produced (the extruder opens directly into the latter through an opening in the wall of the mold).
  • the extruder opens directly into the latter through an opening in the wall of the mold.
  • the pressure of the injection of the material into the mold is provided by the thrust force exerted on the mixture by the screw of the extruder.
  • a portion of the injection pressure will be provided by the emulsification.
  • the residence time of the material in the extruder will preferably be calculated so that the emulsification takes place in the extruder and not in the mold (because in the latter case, the amount of material to be introduced in the mold is more difficult to determine).
  • the mold is immersed in a bath of cold water, for example at a temperature of less than or equal to 20 ° C.
  • a bath of cold water for example at a temperature of less than or equal to 20 ° C.
  • Other modes of cooling are of course usable and in particular the dipping of the parts themselves in a bath or the maintenance of parts or molds containing them in a flow of cold gas.
  • the pallet may be made of other materials than that described.
  • the elements 10 and 30 may in particular be formed of wooden planks while the beams 20 are made of the thermoplastic material described above or of a plastic material having mechanical characteristics suitable for this use, this plastic material being recycled or not recycled.
  • the wooden planks are conventionally nailed to the section 20. Compared with a conventional wooden pallet, this structure makes it possible to improve the tear resistance of the wooden planks.
  • the material used for one or more of the elements of the pallet may be a composite material of conventional type.
