Definitions

  • the invention relates to a made of plastic Transport pallet according to the preamble of the claim 1.
  • DE-A-26 55 593 (US 4,316,419) is already one Transport pallet known in which each basis for saving of plastic material has a lattice-like structure, so that the top and bottom are one Have a plurality of openings.
  • the base body is arranged in the manner of pallet feet Provide blocks that over the from the grid-forming Elements taken up in elements Jump towards the other body and that to form the pallet with each other permanently are connected. Remains between the two bases thus a free space for the engagement of the fork a forklift.
  • the grid-forming Elements are rib-like and their distance is less than the width of a fork link of the forklift kept from entering the fork the area of these ribs and a possible one Damage is prevented.
  • This well-known palette has a very complex one Shaping through which effective cleaning is severely disabled.
  • the overall height of the pallet is considerable and does not correspond to the wish for as much as possible flat, space-saving pallets.
  • the reinforcing members of the possible action corrosive Exposed to fabrics so that their lifespan is limited unless specifically high quality material, such as Stainless steel.
  • US-A-3,938,448 describes a generic transport pallet, which is made of two basic bodies.
  • the base body has an essentially square base plate with rounded corners, which have an outer surface and a Has inside surface. From the inner surface of the base plate each Base body are each vertical beams with the same height from. There are two beams with parallel opposite one another Edges of the base plate arranged in alignment throughout. Between the two edge supports is parallel to it central carrier provided. Each carrier is made up of two to each other parallel strips formed by a front Edge web are connected. On the inside of the base plate are reinforcement ribs in the area of the beams and between the beams educated. Every body is in one Piece of thermoplastic resin through a highly effective Molding processes such as injection molding. The connection the two basic bodies are along the two Basic bodies each with the same height and Edge webs by melting and melting these areas pressed against each other. The palette thus obtained has cavities within the carrier and two between the carriers parallel open channels for the engagement of the forks one Stacker.
  • US-A-4,397,247 describes one-piece rotation molding made of fast curing resin material Plastic pallet.
  • the palette is rectangular and has one Top, one underside, two longitudinal edges and two transverse edges. Parallel to the longitudinal edges are in the pallet to each other parallel hollow channels formed, two of which with go through rectangular cross section and the inclusion of the Enable a truck.
  • the rest parallel to it Hollow channels are either open or in the area of the transverse sides completed by foam injected into the hollow channels.
  • reinforcement beams are arranged, previously positioned in the injection mold accordingly are.
  • WO -A- 87/05581 shows a pallet that is used as a load-bearing Element has a honeycomb structure, the through on one or both sides with the honeycomb Structure by gluing, welding or the like. tightly connected plates is covered, being in the Cells of the honeycomb structure shock-absorbing and - absorbent air cushions are included. Between the honeycomb structure becomes the plate edges closed off from the outside by a peripheral edge. With one of the plates are protruding outwards Feet connected.
  • honeycomb structure precludes the possibility that Pallet made of elastic plastic if required Rigid inlays, especially made of metal, keep their shape to design or increase the load capacity.
  • the one described in WO-A-87/05581 Pallet consist of an upper part and a lower part, whose honeycomb structures are heated to such an extent that when pressed against each other, with each other connect, with the connection plane in the thick middle of the plate so formed or somewhere between the covering ones Plates can lie.
  • the FR-A-2 206 248 shows a pallet made up of two Compression molding or other preformed plates Synthetic resin is made by the edge and on intermediate surfaces Plasticization of these sites are interconnected.
  • the Preforming is carried out in such a way that protruding and open feet are formed on the other side, the outside can be equipped with sliding shoes. Between Feet become reinforcing parallel hollow channels and on the circumference adjacent to a circumferential connecting web Hollow channel through appropriate preforming of the plates educated.
  • the plate has no smooth surfaces. you The edge web stands outwards from the wall of the circumferential hollow channel from.
  • US-A-4 879 956 shows one of the range of FR-A-2 206 248 very similar palette, whose plates between each other related hollow channels on the end faces of circular indentations connected in each plate are in which a through channel are provided can.
  • EP -A- 0 277 033 describes a transport pallet described, which - except for on the underside of support feet Skids to be attached - including the support feet is made in one piece from plastic.
  • This Pallet has a flat plate as the upper limit, from which molded reinforcing ribs, themselves mutually often at different intervals crossing, jutting down. This makes a variety formed by downwardly open chambers. The introduction of continuous, rigid stiffeners can not.
  • chambers open upwards, in the center for inserting the connecting pins formed on the runners vertical, closed at the top and open hollow chambers are arranged below.
  • this pallet construction not suitable for the arrangement of rigid stiffening inserts, it has and is diverse open cavities Especially structured on its underside, that one that meets today's regulations Cleaning at a reasonable cost is hardly possible.
  • Pallet can also be produced as inexpensively as possible be a high load-bearing capacity and a long service life, as low as possible, which in particular for the return transport of Empty pallets is significant.
  • the transport pallet according to the invention has smooth, easy to clean surfaces, and exhibits because of their internal structure and the
  • the transport range can be kept relatively flat overall and thus enables a low overall height. Because the transport pallet runs along its circumference is closed, it cannot be caused by incorrect intervention the fork of a forklift may be damaged.
  • the transport range can be inexpensively made of plasticized Plastic waste, especially unsorted Household plastic waste.
  • This Material is, also due to its polyethylene content, particularly tough, tough, inelastic and unbreakable, and may be included due to Mend body or because Fluctuations in the composition and thereby conditional changing melting points only in the pressing process are processed.
  • chambers sealed off from the outside Depending on the expected load, several or all with one reinforcement insert each be provided before the two base bodies together, preferably by vibration or mirror welding, be connected to each other. Because the Reinforcement inserts tightly enclosed in the chambers are and also during the welding process Moisture in the chambers is reduced for Reinforcement inserts made of metal no risk of corrosion, so that inexpensive alloys are used can be. It is related to use one inexpensive on the one hand and yet therefore very resistant plastic material also the ability to use relatively aggressive cleaning agents to use.
  • the length of the reinforcement insert considering thermal Length changes of the pallet on the one hand and the reinforcement insert on the other hand dimensioned so that also at the maximum expected limit temperatures no disturbing effects are to be feared.
  • the strips, crossbars and edge strips with the Height about the base distance of the base body Basic body is provided with the feet.
  • the element two groups of pairs has parallel strips, the The direction of the ledges of one group the direction of the Strips of the other group cuts and in the cutting area of each pair of strips of the one group with a pair of strips from the other group are interrupted in such a way that that of all pairs of strips included grooves in connection stand.
  • the feet are preferably designed as hollow bodies and in one that is kept free by the pairs of strips Area arranged, their cross section in Towards their free end steadily tapered and that of surface of the pallet facing away from everyone one of the feet opposite to insert one Has suitable opening, whereby the cavity enclosed by the feet towards on this opening opens and the Area between the opening and the foot load-bearing basic body with one close to both bases subsequent wall is enclosed, the Inner wall surface aligned with the inner wall surface of the foot.
  • the feet are conveniently on them molded on adjacent base body.
  • the runners can be detached be connected to the feet, but is preferred a variant in which the pallet and runners are inseparable Form unity.
  • the runners from a foot-connected open, tub - like top and one covering its opening and with it tightly connected to form a hollow body Lower part.
  • the top is on its Feet facing longitudinal edges beveled to to facilitate the insertion of forklift forks.
  • a particularly useful embodiment is that the runners are formed by on the upper part Longitudinal ribs are divided into chambers, whereby at least one of the chambers has a rigid reinforcing insert may contain through the tight connection corrosion-protected on the upper and lower part of the runner is trapped in the chamber.
  • this is Bottom part designed as a flat lid, the edges of the upper part and possibly its longitudinal ribs has associated welding approaches.
  • the pallet and skids as an inseparable unit, there is an appropriate design in that the feet act as a downward open frame are molded onto the underside of the pallet frames shaped according to the runners are assigned, and that the associated Frame at the bottom and on the runners with formation each of a dense cavity welded together are.
