Definitions

  • the invention relates to a plastic pallet for transporting goods and for storage of goods.
  • This pallet is made of a fiber-reinforced plastic. It has a plate body in honeycomb construction, are attached to the bottom of feet. The plate body is formed closed on all sides. Especially he has a continuous closed top. It consists of at least two plate halves, which are connected by a large parallel to the top weld.
  • the plastic material insert is relatively high for such a pallet.
  • the WO 94/10051 discloses a plastic pallet with closed top, two-part plate body.
  • the plate body consists of two honeycombed plates, which are connected to each other, for example, welded.
  • the US 6,357,366 B1 discloses a pallet based on a footed plate.
  • the plate is formed by a honeycomb body made by welding two flat honeycomb plates.
  • a similar concept also reveals the US 2003/0110990 A1 ,
  • a plastic pallet which has a corrugated structure in cross-section.
  • the pallet has ribs arranged in parallel with each other and grooves formed therebetween which form the corrugated structure.
  • the ribs and the grooves are interconnected by web walls which are oriented parallel to each other.
  • the web wall sections provided in the ribs are aligned with web wall sections which are provided in the channels. This results in an undercut-free reasonably stable construction.
  • Plastic pallets with a corrugated structure are also made of GB 1133759 A known. This document discloses pallets whose waves form mutually concentric rectangular, annular ribs and grooves.
  • the NL 301347 A discloses a pallet with hollow profile pipe sections which are interconnected by a triangular grid.
  • the structure is not interchangeable.
  • the plastic pallet according to the invention has a plate body having on its upper side a rib structure consisting of mutually preferably parallel downwardly open hollow ribs, wherein between the ribs at the top open grooves are formed, in which web walls are arranged.
  • the plate body is "open" both above and below. In other words, its bottom as well as its top are interrupted several times.
  • Its upper level is determined by the preferably flat top surfaces of the ribs, which are preferably located in a common plane.
  • Its lower side is defined by the preferably a common plane defining, preferably flat undersides of the flat bottoms.
  • the plate body can have a corrugated structure in cross section, similar to, for example, a corrugated sheet with a suitable rib cross section, for example trapezoidal cross section.
  • the wave structure causes a high bending stiffness with respect to the longitudinal direction of the ribs and grooves.
  • the gutters and the interior of the ribs accessible from below are provided with web walls.
  • the web walls cross the upwardly open channel or the downwardly open rib.
  • the gutter traversing a gutter wall is aligned with the two adjacent, the respective adjacent rib crossing web walls.
  • the web walls thus form web wall chains which extend transversely to the rib structure over the entire plate body.
  • the web walls provide great flexural rigidity in a direction transverse to the ribs and gutters.
  • This concept increases the bending stiffness of the plate body and its load capacity and thus results in a total plate body that can be produced with little material.
  • plastic material is completely or partially foamed by physical and / or chemical processes.
  • the plastic pallet is then formed by a preferably fiber-reinforced foam body.
  • the foaming of the plastic body may, if necessary, be limited to certain selected zones.
  • the web walls which according to the invention are arranged obliquely to the ribs and substantially striving away from the disk center, provide a production-technically significant advantage.
  • the plastic pallet can then be manufactured with a few sprues, for example, with only a single central sprue by injection molding.
  • the web walls also form flow paths for the plastic propagating from the disk center.
  • the shape of the plate body is free of undercuts, so that it can be produced with a simple injection mold, which manages with little or no moving moldings.
  • the proposed geometry leads both to a high flexural rigidity and load capacity of the plate body with low material usage as well as favorable and simple manufacturing conditions with regard to an injection molding process, for example, considered for the production. The same applies when using a transfer molding process or a pressing process.
  • openings are incorporated into the floors and / or the tops of the grooves or ribs. These openings are preferably formed as punched holes. This has the advantage that on the one hand reduces the plate weight and recoverable in the form of punching waste for the production of said plastic pallets usable recyclable material. On the other hand, the injection molding process is favored in the production. There are no binding or flow seams.
  • the openings are arranged in rows along the entire longitudinal extent of the ribs or channels.
  • the shape of the openings can be chosen appropriately.
  • the web walls and the side walls of the ribs and grooves are preferably formed without interruption. Not necessarily, but preferably the ribs and gutters have a uniform wall thickness.
  • the wall thickness of the side walls of the gutters and ribs can match the wall thickness of the floors and tops of the plate body as well as the wall thickness of the web walls. This optimizes the flow properties the plastic in the manufacturing process and provides sufficient stability of the plate body with low material usage.
  • feet are molded onto the plate body.
  • the feet can be an integral part of the plate body and merge seamlessly and seamlessly into these.
  • the feet are formed by both top and bottom open hollow structures. This can be achieved by the feet having side walls extending downwardly from the underside of the panel body, which transition into a lower surface from which an elevation extends upwardly. The space between the elevation and the insides of the feet is open at the top.
  • the interior of the survey is preferably open at the bottom.
  • the survey may have a final with the ribs upper side. Thereby, the upper bearing surface of the plastic pallet is formed by the tops of the ribs and the upper side of the feet.

  • the plastic pallet is formed of a fiber-reinforced plastic.
  • a reinforced by long fibers thermoplastic is preferably used.
  • the long fibers have a majority of a length of preferably more than 2 mm.
  • the long fiber content can be selected appropriately on the plastic. For example, it may be 20% to 30%.
