Definitions

  • the invention relates to a pallet, in particular for transporting goods.
  • pallets of uniform dimensions are used on a large scale, which usually circulate in the context of deposit systems.
  • the pallets are used to hold the packaged and lashed goods for transport by forklift, truck or train, as well as to store the goods in warehouses.
  • This pallet has an upper deck, closed at its upper side by a flat, closed surface. On its underside honeycomb cells are formed.
  • the pallet also includes a lower deck closed at the bottom and fitted with honeycomb cells at the top. The two decks are welded together flat. From below, feet are welded to the lower deck, three of which are connected to each other by a bridge.
  • This pallet is suitable as a hygiene pallet, especially for the transport of food. However, it is subject to restrictions in terms of resilience. Will the
  • the pallet according to the invention has a lower pallet deck, on which feet are integrally formed.
  • the upper pallet deck and the lower pallet deck are welded together. This weld is the only essential weld on the pallet.
  • the pallet decks are made of a fiber-reinforced plastic, preferably a long-fiber reinforced plastic, pallets can be produced which, with the same dimensions as a wooden pallet, can carry higher loads than these.
  • the welded joint is limited to the plane between the two upper decks.
  • the fibers embedded in the plastic for example glass fibers of 6 to 25 mm in length, initially face each other with their front sides. When the weld is formed, beads form on the honeycomb edges in which the fibers are entangled or matted together.
  • the fibers are otherwise wall-parallel, ie oriented predominantly approximately parallel to the outer sides and other surfaces of the decks and the honeycomb cell walls.
  • the long glass fibers or other fibers flowing with the plastic thus also wrap around bends and corners of the plastic without breaking, so that the formed feet are produced without interrupting the course of the fibers. This results in a high strength.
  • no glass fiber reinforced transition can be achieved, ie the fibers do not pass through the seam.
  • the invention helps here and leads to a Design in which the fibers of the lower deck - interruption-free extend into the feet.
  • the pallet decks are preferably mirror-welded together.
  • the edges of the honeycomb cells are heated over their entire surface and pressed against each other so that the fibers are entangled and the plastics frayed.
  • other welding methods such as friction welding, ultrasonic welding or suitable bonding can be used.
  • the upper and lower pallet deck can be made of the same plastic. However, it is also possible to manufacture the pallet decks of different plastics. For example, the upper pallet deck can be made of a primary plastic and the lower pallet deck made of a recycled plastic. This results in an upward, i. on the side facing the goods, a hygienic harmless surface while the lower pallet deck can be produced at a reduced cost.
  • long fiber-filled plastics are preferred. These contain glass fibers or other fibers whose average length of fibers is significantly greater than the thickness of the walls to be produced.
  • a suitable manufacturing method for example a transfer molding method, it is possible to achieve that the fibers in the production process are aligned parallel to the wall, ie parallel to the respectively adjacent surface. Smooth surfaces are obtained from which no fiber ends protrude. This is to be preferred both from the point of view of material strength and from the point of view of surface quality and hygiene.
  • a suitable manufacturing driving is a transfer molding process in which viscoplastic, fiber-filled plastic is injected into a partially closed injection molding mold, after which the mold is completely closed. The injection into the not yet completely closed form has the advantage that a good mold filling can be achieved. The subsequent closing of the mold is similar to a pressing process, in which the alignment of the fibers is achieved by the flow of the plastic plastic.
  • Both pallet decks preferably have uniform and congruent honeycomb patterns. This ensures that when welding the pallet decks, the edges of the honeycomb cells meet to form a bead-like weld seam. In this case, preferably as much material is laterally displaced from the honeycomb cell edges that forms an almost closed surface between the pallet decks. In this way, a good entanglement of the fibers contained in the plastic is achieved in the weld region. In addition, in this way, the height of the produced, forming the pallet composite plate can be regulated.
  • the feet have a honeycomb cell pattern that differs from the rest of the honeycomb cell pattern of the lower pallet deck.
  • the honeycomb cells in the feet are preferably much larger than the other honeycomb cells of the lower pallet deck. This facilitates the molding of the lower pallet deck after the transfer molding process.
  • each foot has an intermediate floor. This is arranged, for example, below the middle of the height of the foot. Further preferably lies This intermediate floor above bars that connect the lower ends of the feet together.
  • the intermediate floor gives the feet lateral rigidity, so that they do not collapse even when they are under considerable load and are pushed, for example, with the tips of the forks of a fork-lift truck.
  • Below the false bottom further honeycomb cells are preferably arranged, these honeycomb cells then being open towards the bottom.
  • the lower honeycomb cells preferably differ from the upper honeycomb cells. They can have a considerably smaller cross-section than the upper honeycomb cells. This too can benefit the firmness of the feet.
  • the intermediate floor is at a height of, for example, 30 to 70 mm in a region which is usually hit by the tip of a fork-lift fork lying on the ground.
  • the webs connecting the feet are preferably provided with ribs on their underside.
  • the spaces between the ribs are open. This has the advantage that the pallet thus formed gets a secure footing even on uneven ground. Individual pebbles or other smaller objects lying on the floor are neither pressed into the ground nor do they cause a pallet to tip over. Rather, they find themselves in the honeycomb cells of the feet or between the ribs of the webs.
  • the plastic pallets have closed honeycomb cells.
  • they can have a receiving compartment for receiving a manually optically or a machine-readable data carrier.
  • the receptacle can be a honeycomb cell.
  • the receptacle can also be arranged in a mechanically slightly loaded, visible from the outside and protected area, such as a tray be arranged on an outside of a foot.
  • This compartment can be provided with a viewing window, wherein it can be designed so that manually readable data carriers, such as labels or cards, can be inserted.
  • manually readable data carriers such as labels or cards
  • Disk such as by radio waves or other radiation readable chips to install in the range.
  • identification devices usually contain a flat coil and a chip connected thereto. At least the reading of data that can identify the pallet can be done by high frequency radio waves.
  • identification devices are often referred to as RF-ID devices.
  • this device can also be created in such a way that information can be introduced into the identification device in order to identify, for example, the goods lying on the pallet.
  • the identification device only serves the distinctive marking of the pallet. Both variants can be used to achieve local, regional or global pallet tracking.
  • the corresponding identification devices can be permanently installed in the pallets, for example embedded in their plastic. This can be done in the production of pallets in the transfer molding process. If required, the identification devices can be surrounded by a jacket, which protects them from being exposed to high temperatures of the viscoplastic during manufacture when it flows around the identification device.
  • the identification device in a honeycomb cell, preferably the lower pallet deck, For example, insert an external honeycomb cell of a pallet foot before the lower pallet deck is welded to the upper pallet deck.
  • the identification device can be secured in place in the honeycomb cell by foam or other suitable holding means in place, for example to keep it on the outside. Also in this case, the identification device is held captive in the pallet.
  • the identification device is provided with a communication interface which can communicate with external devices, for example via radio waves, it is considered advantageous to accommodate the identification device in a chamber of the pallet, which is largely protected against damage and external harmful influences.
  • a chamber may for example be formed by a honeycomb cell which does not border on an outer wall of the pallet.
  • the honeycomb cell can be arranged in one of the feet or in other honeycomb cells of the lower pallet deck.
  • the identification device can serve to mark the pallet unmistakably in order to be able to record and track these individually.
  • the identification device can be a passive or active device, in the latter case it preferably has its own voltage source, eg a long-term storage battery of high capacity.
  • the identification device then has, for example, a reception module and a transmission module, with which it can be addressed remotely by means of HF and then respond with an acknowledgment signal.
  • This can be served by the existing wireless cell network, which otherwise serves mobile communications.
  • This enables pallet tracking and locating lost pallets or loads by: the radio cell is identified in which the transmission module of the pallet has registered.

Abstract

Un nouveau type de palette en plastique (1) présente deux plateaux (2, 9), simplement reliés entre eux par un seul cordon de soudure (32). Le cordon de soudure se trouve de préférence dans une fibre neutre de la palette (1). La palette (1) présente des dimensions extérieures conformes aux palettes EURO traditionnelles. Elle présente cependant une longévité, une hygiène et une capacité de chargement supérieures à celles-ci. Une installation d'identification peut être intégrée dans la palette (1), les données sont enregistrées ou maintenues à disposition sous une forme lisible par ordinateur et transmises de préférence à la demande. L'installation d'identification ne dispose pour son fonctionnement de préférence d'aucune batterie ou accumulateur d'énergie similaire mais reçoit son énergie de fonctionnement en même temps qu'un signal d'interrogation. Elle permet la construction d'un système de palettes avec un suivi individualisé des palettes. Si l'installation d'identification est programmable, elle peut également enregistrer et transmettre à la demande les données qui concernent le type, la quantité, le lieu de destination ou diverses caractéristiques des marchandises.
