Definitions

  • This invention relates to improvements in design and materials used in wooden pallets for use in the packing and transporting of goods industries.
  • pallets of variable size, depending upon the individual requirements of both the product and user.
  • Such pallets provide a solid base ontcPwhich goods can be loaded, while further providing a structure- which can be handled with standard moving equipment.
  • the use of pallets not only allows for many small items to be packaged and carried in one convenient unit, but further provides a level of protection for the goods as they are supported away from the ground and do not come into contact with the lifting and moving equipment.
  • Pallets are typically made from wood, for several reasons: wood, as a material, is readily fashioned into the necessary parts to make up a pallet and can easily be assembled. It exhibits the necessary strength for carrying and transporting even large and heavy equipment, whilst further being a relatively inexpensive raw material.
  • the pallet will comprise a top surface constructed from a plurality of parallel slats, which are fastened to underlying perpendicularly aligned support structures. These underlying structures may simply be further slats used to fix the base slats in place; or, they may be large blocks running the length of the pallet, which are used to support the platform away from the ground and give the necessary clearance to allow the lifting equipment underneath.
  • pallet supports have spacer blocks separating two sets of platform slats by the necessary amount to allow the lifting equipment access.
  • a further option is to use spacer blocks separating the platform slats from a pallet base, wherein the spacer blocks are located such that the lifting truck can access and lift the pallet from any side.
  • Wooden pallets are possessed of certain undesirable properties which will tend to limit their usable lifetime.
  • wood is a hygroscopic material: prolonged exposure to rain and moisture in the atmosphere causes the wood to absorb water, which eventually leads to the wood rotting.
  • the wood in the pallets becomes wet, it swells and becomes soft, which reduces the overall strength of the pallet and can lead to failure.
  • the wood does not grip the nails holding it together with enough force, which can lead to the pallet falling apart, or not being able to withstand impacts.
  • the hygroscopic nature of the wooden feet combined with capillary action, will transfer moisture from the ground up to the goods sitting on the pallet.
  • the pallet feet It is not uncommon for the pallet feet to be constructed from a combination of wood shavings and a urea based resin, rather than from cut timber blocks, the two being combined and the wooden blocks moulded under high pressure. Unfortunately, this urea resin is poisonous, and the fumes which are generated when the old unusable pallets are burned, are also toxic. Further, such composite feet are less resilient to water than pure timber, tending to expand greatly upon exposure to moisture. Once in this expanded state, the feet are more greatly susceptible to damage from being knocked or from being iff contact with the forks of the pallet truck.
  • the pallets are constructed from plastic.
  • the pallet is injection moulded as a single piece, and the full pallet is realised in one moulding.
  • plastic pallets do not suffer from the same problems induced by exposure to water, as detailed above for wooden pallets.
  • the manufacture of full plastic pallets requires very large plastic injection moulding machines, as these pallets can be larger than 1 m to a side. Coupling this with the cost of the plastic, means that full plastic pallets, whilst desirable, are often too expensive for the end user.
  • a pallet spacer made from a composite plastic material wherein the plastic comprises a mixture of an elastomeric substance and a thermoplastic binder.
  • the plastic material has an internal elasticity as a result of the elastomeric substance, which acts to generate a radial gripping force; such a gripping force could act to grip the shaft of a nail which was located therein.
  • Such a pallet spacer is formed from the plastic material by following the steps of: melting the thermoplastic material and combining this with the elastomeric substance; mixing the thermoplastic material and elastomeric material in an extruder; injection moulding the composite material into a pre-designed mould and allowing the composite to cool to form the solid structure.
  • Figure 1 shows a packaging pallet with composite material spacers integrated into the design.
  • This invention discusses a new composite thermoplastic and elastomeric material and method of manufacture and use thereof, for improving the lifetime and water resistant properties of packaging pallets.
  • this material can be integrated with traditional methods of pallet construction, being used as a straight replacement for wooden components.
  • the current invention is directed toward incorporating the new plastic material within traditional wooden pallets, by replacing at least some of the wooden components. This is made possible by virtue of the method of manufacture of the plastic pieces, which allows for fabrication of any shape or design.
  • a further component is the internal structure of the composite, which shows a degree of elasticity that radially grips the shaft of a nail. being used to fasten together the constituent parts of a pallet.
  • the plastic composite does not exhibit the hygroscopic properties of wood, it is not degraded by prolonged exposure to water, and so can substantially lengthen the lifetime of the pallets.
  • the composite prevents the development of insect eggs and maggots as the humidity within the material is very low; this is particularly advantageous with regard to the import and export of wooden products, and the increasing necessity to certify the wood as insect and larvae free.
  • Figure 1 shows one possible embodiment of integrating the new material within a pallet.
  • the spacers (2) have been fabricated as simple blocks which are located between the platform (1) and the pallet base (3).
  • any design for the spacers (2) or base supports is possible, and that the simple blocks shown in the figure are for illustration only. Any structure that can be conceived and formed from wood can readily be duplicated by the plastic composite. Indeed, it is possible to fabricate an entire pallet from the composite, either as a single formed unit, or by producing individual parts and fixing together as in the case of wooden pallets.
  • the plastic composite is formed from a combination of both a thermoplastic material and an elastomeric material.
  • Suitable thermoplastic materials are any of the range of polyolefins, for example polyethylene or polypropylene, ethyl vinyl acetate (EVA) or thermoplastics such as: polyurethane or polyvinylchloride (PVC), or other suitable substances such as any of the range of polyamides.
  • EVA ethyl vinyl acetate
  • PVC polyurethane or polyvinylchloride
  • a key advantage of using a polyolefin, however, is that it can be obtained from scrap and waste plastic, such as old detergent bottles, -thereby reducing costs.
  • Any elastomeric compound, such as natural -rubber or a synthetic substitute is appropriate for incorporation within the thermoplastic; once again, recovered waste materials from industries such as tyre or shoe manufacturing provide a suitable supply, at negligible cost.
  • Production of the composite structures is by injection moulding of the two constituent materials from an extruder.
  • the elastomer is ground up into small fragments, lying somewhere in the range of 0.1 to 5mm in size, and is combined with the melted thermoplastic in the extruder.
  • the operating temperature at this stage is carefully chosen, to ensure that the thermoplastic is in a molten state when it is mixed with the elastomer, but the elastomer remains a solid.
  • thermoplastic binder gives a rigidity to the composite and a hard outer shell, which confers the required resistance to shock impact and allows it to be used as a replacement for wood.
  • the elastomer being combined with the thermoplastic as a solid in its natural cross-linked or vulcanised state, so as to create a suspension, the composite is endowed with an internal elasticity. This elasticity is vital, as it both allows nails to be hammered into the material, as well as subsequently providing a radial compression which grips the shaft of the nail, holding it in place. It is this combination of the more rigid thermoplastic polymer with the elastic elastomer which creates the final composite having similar physical properties to wood, without the drawbacks of a hygroscopic nature and the subsequent problems associated with this.
  • the ratio of thermoplastic to elastomeric materials within the composite can be adjusted to change the physical properties of the final material. These properties include, but are not limited to: density, surface hardness and internal elasticity (how tightly the composite grips a nail). For example, a plastic block comprising entirely thermoplastic material with no elastomer provides a very hard structure, however, it is too hard to allow the insertion of a nail and therefore cannot be incorporated within a wooden pallet. Likewise, if too much elastomer is used, the resulting structure is rather too soft and does not show the required rigidity or resistance to impacts. Depending upon individual user requirements, the percentage by volume composition of the composite can range from an elastomer composition of between 15-80%.
  • the ratio by volume composition preferably lies between 50:50 to 40:60, thermoplastic : elastomer, which gives the desired wood-like physical properties. Changing this composition ratio will change the density of the final material, and additionally the radial gripping force applied to the shaft of a nail therein. It is possible to select the composition such that the "pool out” or “pull out” force, which is the force required to be applied to a nail held in the material so as to remove it, lies between ⁇ 500N and ⁇ 2500N. For use in pallets, however, it is most desirable to have a minimum force requirement of 700N, to ensure that the pallet can withstand normal usage. The actual density, and therefore pool out force property, can be chosen by the end user, and may be selected on the basis of the equipment being used by the client for pallet manufacture, and the specific capabilities of this.
  • thermoplastic A key advantage to the composite, is that there is no requirement for using particularly high quality raw materials.
  • both the elastomer and the thermoplastic can be obtained as scrap or waste material from other industries, household refuse collections or as films co-extruded from multilayered plastic materials.
  • any compound with elastomeric properties is suitable for the elastomer, the only requirement being that the compound remains as a solid during the mixing and extruding step with the thermoplastic.
  • Suitable materials, in addition to natural rubber as detailed above, which have been shown to combine effectively into the composite include glass fibres and indeed wood shavings themselves.
  • the desired water resistant properties are unaffected by the choice of material.
  • thermoplastic material can be coloured when it is used for its initial purpose, prior to being discarded and melted down to be used in the composite, it is possible to add pigmentation to the composite material. Indeed, the process of injection moulding will yield a product which has an outer surface that is primarily composed of the thermoplastic, with the elastomer uniformly distributed throughout the interior. As such, it is clear that the use of a coloured plastic or standard pigmentation within the thermoplastic melt will give a coloured final product.

Abstract

La majorité des marchandises manufacturées sont expédiées de l'installation de production, directement jusqu'au consommateur final, ou vers des points de vente. Le transport de ces marchandises est facilité lorsqu'elles sont emballées sur des palettes en bois qui peuvent aisément être déplacées au moyen d'un transpalette. Néanmoins, ces palettes en bois présentent des problèmes significatifs qui sont liés à la nature hygroscopique du bois, notamment au niveau de structures de support destinées à maintenir la plateforme des palettes au-dessus du sol tout en laissant suffisamment d'espace pour permettre l'accès du transpalette. Lorsque le bois est exposé à l'eau, il ramollit et s'affaiblit, ce qui augmente le risque de détérioration des palettes lors d'une manipulation ordinaire. Pour résoudre ces problèmes, un matériau composite plastique est créé. Ce matériau peut facilement être incorporé dans les palettes en bois et n'est pas de nature hygroscopique. Ledit matériau est particulièrement avantageux dans la mesure où il peut être façonné pour prendre une forme quelconque, et présente des propriétés physiques analogues à celles du bois.
