Definitions

  • the present invention relates to a new type of pallet making it possible to carry out the shopping, the handling of various products.
  • pallets are well known devices used in many technical fields and can be defined, in general, as assemblies serving as supports for stacked products. These devices consist essentially of a tray on which the products are arranged and which has beneath its underside passages allowing the introduction of the forks of handling equipment, such as forklifts.
  • the pallets are generally made of wood and can be classified into two main categories, the first according to which the assembly comprises a single tray (or floor) fixed on parallel supports (battens) defining between them passage zones for the forks of the machines, the second being made up of two parallel plates connected to each other by also parallel spacers for the passage of the forks of the carriages.
  • the pallets can include fixed or removable uprights, making it easier to hold loads or allowing the stacking of several loads without damaging the goods.
  • the pallet according to the invention is obtained by vibrated molding and comprises, in known manner, a plate, the lower part of which is associated with parallel cleats defining spaces for the passage of the forks of the handling mandrel and it is characterized in that: - the basic material used to make it is concrete in which an additive is incorporated which makes it light and increases its mechanical characteristics; - the battens provided in the lower part are four in number symmetrically arranged on either side of the median plane of the support plate itself, the said battens being connected to the lower base of the plate by portions in the form of an arc reinforcing the resistance of the whole.
  • a particular material namely a concrete loaded with an additive making it possible to lighten it and more particularly an additive made up of aggregates or aggregates such as those obtained.
  • the molding operation is carried out in a particular way, namely that, in general, initially the poured concrete is first vibrated then that, in a second step, we realize a compact mechanical level either through holes for pouring concrete into the mold, holes which, moreover, make it possible to define the cleats that the pallet comprises, or by exerting pressure on the surface of the plate (for example by a smoothing operation) , the mold being in this case positioned with the feet of the pallet down; the product is then dried in an oven and finally demolded.
  • the molding operation is based on the principle of compression in a hollow rectangular mold into which a quantity of concrete is poured, the volume of which equals the final liter of the pallet.
  • the vibration and the mechanical compaction are carried out by means of a pestle representing the underside of said pallet in negative and whose pounding action occurs during the vibration and generates the final shape of the underside of the pallet while determining the thickness of the plate and generating the rise of material in the feet or cleats.
  • the plate is fed and vibrated first, then the feet.
  • a mold in two parts which intervene one after the other with a two-level drawer which feeds one mold after another.
  • a mold representing an upside-down tray is fed by a drawer which fills it then withdraws during a first vibration.
  • a second core mold then descends and fed by the second level of drawer, allows the establishment of the feet which are in turn vibrated and pounded.
  • the assembly of the two half-molds (which constitute what is called a double mold) then emerges together from the top.
  • a quantity of concrete is poured, the volume of which equals the final bedding of the pallet inside a hollow rectangular mold, then a vibration operation is carried out followed by a smoothing exerting pressure on the surface of the plate, the mold being in this embodiment positioned with the feet of the pallet down.
  • the molded product is then steamed before being demolded.
  • the pallet according to the invention which is obtained by molding essentially consists of a tray, designated by the general reference (1), this tray having under his lower face higher parts in relief (2) forming a cleat.
  • These raised parts (2) are, in accordance with the invention, four in number and are arranged symmetrically on either side of the median plane XX of the support plate (1) proper.
  • the two intermediate battens (2a, 2b) are relatively close to said plane of symmetry XX and spaced from one another by a distance of the order of a few centimeters, while the two extreme battens (2c, 2d) are , meanwhile, arranged near the sides (3,4) of the plate (1).
  • cleats (2a, 2d) extend over the entire length L of the plate (1). Furthermore, the areas of connection of the cleats (2a, 2d) with the lower face (5) of the plate (1) are produced according to a curved profile reinforcing the molded assembly.
  • Such a pallet is obtained by molding a concrete loaded with an additive making it possible to lighten it and more particularly, of an additive consisting of aggregates or aggregates such as those obtained according to the teachings of FR-A-2 499 551
  • an additive consisting of aggregates or aggregates such as those obtained according to the teachings of FR-A-2 499 551
  • a molding composition it is possible to use a concrete consisting of lignocellulosic aggregate with optionally the addition of polypropylene fibers.
  • This molding operation is carried out in the manner illustrated in FIGS. 2 and 3 using a mold (6) comprising, on the one hand a box (7) of actual molding with which are associated cores (8) defining the shape of the battens (2a, 2d) to be carried out.
  • a box (7) With this box (7), there is associated a plate (9) comprising elements (10) on its underside allowing, as will be seen in the following description, to carry out mechanical compaction of the cast material (11) .
  • the box is filled ( 7) the composition of concrete previously prepared.
  • the filling is favored by providing chamfers (13) at the top of the filling orifices (12) formed between the cores (8) of the mold.
  • the material is subjected to a vibration transmitted to the container (6).
  • the mold being filled with a determined quantity of material, in a second step, the plate (9) is lowered so that the pestles (10) which it has on its underside, penetrate inside the orifices ( 12) of the mold. These pestles (10) make it possible to compact the cast material.
  • the pallet is obtained on the principle of compression in a hollow rectangular mold into which is poured a quantity of concrete, the volume of which equals the final bedding of said pallet.
  • the compacting operation is obtained by means of a pestle (20) representing the underside of said pallet in negative. This pestle (20) intervenes during the vibration and generates the final shape of the underside of the pallet by determining the thickness of the plate (1) and generating the rise of material in the feet or cleats (2).
  • a third variant (not illustrated) consists in first supplying the plate (1) then the feet (2). To do this, we use a mold in two parts which intervene one after the other with a drawer on two levels which feed one mold after another. A mold representing an upside-down tray is fed by a drawer which fills it then withdraws during a first vibration. A second core mold then descends and fed by the second level of drawer, allows the establishment of the feet which are in turn vibrated and pounded. The set of two half-molds which constitute what is called a double mold, is then released together from above. Generally, in this variant, the mold gives the same result as the first method described, but by working in two stages, namely the plate then the cleats. Such an operating process is used to date in other fields such as for example to produce "bilayer" type paving stone products.
  • a pallet according to the invention is produced by pouring a quantity of concrete, the volume of which equals the final littering of the pallet inside a hollow rectangular mold, the vibrating being carried out by the same way as in the previous variants.
  • the mold is positioned with the feet of the pallet down and, after vibration, the plate is smoothed.
  • the product is dried in an oven and is then removed from the mold.
  • the pallets thus produced are not only very light, but also have very high resistance, in particular against impact. They can be used for the storage and transport of any type of product and are particularly suitable for handling paving stones of small dimensions which cannot fall as is the case with traditional pallets with holes.
  • the invention is not limited to the embodiments described above, but it covers all the variants produced in the same spirit.
  • the pallets according to the invention have been shown with a full tray (1), for certain applications, it may be envisaged to open up said tray, this openwork operation being carried out during molding , for example when you want to lighten the palette.
