Definitions

  • the invention relates to a pallet made of plastic for one-sided loading with an upper cover plate and a lower cover plate separated from this upper cover plate by spacer blocks and provided with wheel openings.
  • German Offenlegungsschrift 2 0 54 229 range of this type has a lower cover plate with four openings for the wheels of a pallet hand truck.
  • the upper cover plate, possibly together with the spacer blocks, and the lower cover plate of this type of pallet are made of plastic by injection molding.
  • the thickness dimension of the lower cover plate is essentially limited by the requirement that the wheels of a pallet hand truck can still be pushed through the openings in the lower cover plate from the space between the lower and upper cover plates to such an extent that they touch the ground.
  • An essential one The minimum thickness of the upper cover plate standard that is placed on the pallet is that a pallet that is regularly loaded with a certain weight may only have a certain maximum deflection if this pallet is lifted by prongs of a forklift that attack the underside of the upper cover plate . Due to the requirements and standards package mentioned here, the plastic pallets in question, which are intended for heavy loads of, for example, looo kg and more, have a lower cover plate which is thinner than the upper cover plate.
  • the lower cover plate of a pallet rests on the load of a pallet underneath.
  • the weight on the upper cover plate of any pallet is transferred to the load underneath via the blocks and the lower cover plate of this pallet and thereby reaches the upper cover plate of the following pallet below.
  • the parts of the upper cover plate located between the spacers, but also the parts of the lower cover plate play a role in the power transmission.
  • the main thing to consider here is that the cargo consists of sacks or barrels.
  • pallets according to the current state of the art are made of plastic with better mechanical properties.
  • Plastics suitable for a range such as polyethylene, polypropylene, copolymers of ethylene and propylene and mixtures of these homo- and / or copolymers, are mixed with additives, such as glass or asbestos fibers. These are more expensive plastics, which also increase the manufacturing costs of the pallet by the fact that a hard aggregate such as glass causes the injection molding machine to wear heavily.
  • the invention aims to provide a pallet made of plastic for one-sided loading, which comprises an upper cover plate and a lower cover plate separated from this upper cover plate by spacer blocks and provided with wheel openings, the pallet in a surprisingly simple manner a new solution to the disadvantages described offers and switches them off to a considerable extent.
  • the components of the lower cover plate are made entirely or partially of a material with a greater bending strength than that of the material of the upper cover plate.
  • the upper cover plate and the spacer blocks of the pallet according to the invention can be injection molded from non-reinforced material which is cheaper than the material used for the lower cover plate.
  • the wear of the injection molding machine is less if only the lower cover plates are made of material that contains fillers that cause wear.
  • a suitable plastic for the lower cover plate is glass, e.g. Glass fibers, reinforced plastic.
  • the glass can be chemically bound to the plastic.
  • a very suitable material for the lower cover plate is the polypropylene in plate form, which is marketed under the trademark AZDEL by PPG Industries Inc. and is reinforced with endless glass fibers. This plastic combines high bending strength with good machinability by hot pressing, which means that the lower cover plate can be given a profile that increases rigidity in a simple manner.
  • a plastic reinforced with chopped glass fibers chemically bonded to the plastic is also a useful material for the lower ceiling panel.
  • polyethylene or polypropylene with these chemically bonded glass fibers also have a greatly increased flexural strength.
  • the bending strength of the components of the lower cover plate can also be increased by attaching a metal reinforcement therein.
  • This reinforcement then exists e.g. made of straight, hollow aluminum profiles, which are attached in the lower cover plate from spacer block to spacer block. A method for applying this reinforcement is described in the as yet unpublished Dutch patent application ........ together
  • the lower cover plate is made of a plastic which, apart from the means for increasing the bending strength of the components, is of the same type as that from which the upper cover plate and the spacer blocks are made by injection molding.
  • suitable mirror flaps can be successfully placed between the lower cover plate and the spacer blocks.
  • a glue, bolt or snap connection will usually be made.
  • the pallet according to the invention still has a significant advantage. Because of the greater flexural strength of the components of the lower cover plate, the thickness of the upper cover plate can be smaller. In addition to significant material savings, this also means storage space savings.
  • the pallets according to the invention can be put together extremely well loaded with boxes to form a stack
