Description

Field of the invention

The invention relates to a loading unit, which consists of a transport pallet and a resting on this transport pallet and receiving cargo with its loading unloading adapter for machine unloading the cargo without transport pallet.

Background of the invention

Transport pallets are known in various standardized sizes and are used in freight forwarding as a platform on which the cargo to be transported in the form of stackable cargo, individual containers, cardboard or other goods is put together by a goods manufacturer to a loading unit. Such loading units allow the use of forklifts and streamline the handling of goods between different means of transport, for example, in the transhipment of the load from a truck to a rail vehicle or on a ship.

To cope with today's extremely high volume of international goods handling, an immense number of transport pallets are needed worldwide, the largest part of which are designed as so-called reusable pallets, that is, serve several times for transporting goods. It is therefore intended to return the transport pallets after arrival of the load at the wholesaler as soon as possible back to the goods manufacturer, thus saving the claimed by the transport pallets storage capacity at the end wholesaler and to limit the re-production of transport pallets on the replacement of damaged during transport transport pallets , This is however often not possible because the complete load can not be removed and stored mechanically by the transport pallets, but only manually removed in subsets of the transport pallets and forwarded to the retail. Since the transport pallets thus become very hesitant in terms of time, it can take a long time before the required amount of transport pallets for a profitable return transport accumulates. Nevertheless, the piece-by-piece empty transport pallets must be temporarily stored and there are considerable delays in the reusable system.

To avoid these disadvantages was therefore by the EP 0 321 099 A1 proposed a transport pallet, which in the embodiment according to the figures 10 and 11 consists of a base pallet and a discharge adapter, wherein the base pallet is formed by a top plate and a bottom plate, which are interconnected by spacer blocks and extended corner pieces. The unloading adapter, however, is formed from a basis of the extended corner pieces on the top plate of the base pallet and associated with this base plate on which a plurality of equal and the actual cargo area forming cuboid support blocks of different sizes are arranged and fixed so that on each end of the transport pallet each two continuous, spaced apart, intersecting and open towards the cargo channels arise. With this design, it is possible to introduce either the forks of a forklift between upper and lower plate of the base pallet and to transport the load together with the transport pallet or to introduce the forks of the forklift in the channels of the discharge directly under the load and only the load of the To remove transport pallet.

With such a trained transport pallet, the problem of delayed return to the goods manufacturer could be solved, since now the entire load can be immediately removed and stored mechanically by the transport pallet, but it is still problematic, of the transport pallets or unloaded load machine larger subsets To remove cargo. This may be necessary, for example, if at the wholesaler of several transport pallets larger subsets of the load must be removed and put together on other transport pallets for transport to the retailers.

A loading unit, in which at least this problem was solved, is beyond the EP 0 183 600 B1 previously known. This loading unit consists of a conventional transport pallet, on the loading area two auxiliary pallets formed in each case by a lower plate and a spacer blocks with this associated top plate are parked, which receive the cargo to be transported cargo with their loading areas. The cohesion between the individual auxiliary pallets and between each auxiliary pallet and their load is made by a protective cover, which consists of a heat shrinking plastic material. Through the auxiliary pallets, it is thus possible to transport both the entire load together with the transport pallet and to remove portions of the load mechanically by the transport pallet.

As well as the other known transport pallet for ice transport according to US 6,273,006 B1 in which a plurality of auxiliary pallets with corresponding depressions and ribs are arranged on their undersides on a main pallet with ribs and depressions in the surface thereof, it is disadvantageous, however, that a removal of the load is always possible only in conjunction with one of the auxiliary pallets. Although such auxiliary pallets are usually formed only by disposable pallets, nevertheless, their permanent production and disposal causes an avoidable cost, energy and resource costs.

Object of the invention

Based on the stated disadvantages of the known prior art, the invention is therefore an object of the invention to improve a loading unit so that a machine removal of only the load in subsets of the transport pallet is possible.

Summary of the invention

According to the invention this object is achieved in a loading unit according to the preamble of claim 1 such that the unloading adapter is formed by two or more Palettiertablare whose width and depth are matched to the width and depth of the transport pallet, wherein the loading surface of each palletizing tray has a perforated surface and at least two depending, spaced apart, intersecting and open in the direction of the cargo exemptions are arranged on each end face of the rectangularly formed Palletiertablare at least.

Under Palettlertablaren are flat, standardized funding aids for receiving the actual cargo to understand, as they are known in different versions of the storage. The inventive design of such Pallettiertablare with the intersecting exemptions serves the purpose that they provide an opening for engagement of handling means of various kinds. For example, if the two spaced apart forks of a hand pallet truck retracted into these exemptions, so get this with their top to the bottom of the transported piece goods. When raising the gabein upwards they go out of the open in the direction of cargo exemptions and take the load with, while the palletizing tray remains at its starting point. Due to the two-sided arrangement of exemptions, the load can be removed in an advantageous manner from two sides.

Preferred embodiments and further developments of the charging unit designed according to the invention are described in the subclaims.

Thus, it is provided according to claim 2, that the loading area of the palletizing tray is provided on all sides with a border in this way it is ensured that slipping of the load and thus falling from the palletizing tray is prevented.

According to a further feature of the invention according to claim 3, the cargo area of the palletizing tray is viewed from its underside formed lattice-like, with longitudinal and transverse webs intersect in several points, This special construction of the tray its stability is ensured at the same time lightweight construction.

According to claim 4 it is provided that the Palettiertablar consists of a plastic and is made by injection molding, according to claim 5, this plastic polypropylene (PP) to be. Polypropylene is particularly suitable as a material for the palletizing tray, since it can be processed very well by injection molding, has a high impact strength, high rigidity and does not tend to stress cracking.

Finally, in claims 6 and 7, the cohesion of the transport pallet, palletizing tray and load existing loading unit is described. Thereafter, it is provided according to claim 6, that on the upper layer of the load a cover cover is arranged and transport pallet, Palletiertablar, load and end cover are releasably connected together by a fastener, wherein according to claim 7, the fastening means is formed as a strapping.

Detailed descriptions of the drawings

That in the Figures 1 and 2 shown and designated 1 according to the invention Pallettiertablar is integrally formed and made of polypropylene by injection-βen. As FIG. 1 can be seen, the palletizing tray 1 is rectangular and has both at its long and short ends exemptions 2, 3, which are open in the direction of the load upwards. These exemptions 2, 3 are continuous and therefore extend from long end face to long end face and short end face to short end face, so that for the cutting exemptions 2, 3 crossing. points 4 result. The total load area 5 available for the load is composed of two subareas. On the one hand through the partial load. surfaces 5.1, 5.2, 5.3, 5.4, 5.5, 5.6, 5.7, 5.8 and 5.9 and secondly by the exemptions 2, 3 themselves. In other words, the total loading area 5 is not continuous in one plane, but in the manner described by the exemptions 2, 3 interrupted.

As the FIG. 1 Further, the total cargo area 5 is surrounded by a border 6, which is interrupted at eight different circumferential locations due to the exemptions 2, 3. Clearly visible, this border 6 is provided in the area of the exemptions 2, 3 with a conical widening, by which the insertion of the forks of a lift truck or a forklift is facilitated in the Palettiertablar. Likewise is FIG. 1 Also, it can be seen that the partial load areas 5.1 to 5.9 spatially form the top surface of a cuboid, wherein the individual cuboids are connected by a dissected base surface 7, which is formed by the exemptions 2, 3.

In the FIG. 2 shown underside of the tray 1 can be clearly seen the lattice structure, which, as already mentioned, to reduce weight and increase stability. The cuboids bounded at the top by the partial load surfaces 5.1 to 5.9 are hollow as viewed from below due to the lattice structure. The grid structure is formed by a plurality of longitudinal webs 8, which intersect with a plurality of transverse webs 9, so that a plurality of crossing points 10 is formed. The grid structures, the number of which is equivalent to the number of partial load areas 5.1 to 5.9, are interconnected by the base area 7.

In the FIGS. 3, 4 and 5 Load units 11, 12 and 13 are shown, which use different transport pallets 14, 15 and 16 in the expansion. The different extent of the transport pallets 14, 15 and 16 in width and in depth is indicated by the lowercase letters a, b, c and d, where a>b>c> d should be. The figures mentioned are intended to illustrate that the palletizing tray according to the invention can be adapted to any transport pallet size used. If, for example, the spatial dimensions of the transport pallets 14, 15, 16 are set with the values a = 1200 mm, b = 1000 mm, c = 800 mm, d = 600 mm and the expansion of the palletizing tray 1 to 600x400 mm, then there are on the transport pallet 14 five, on the transport pallet 15 four and on the transport pallet 16 three Palettiertablare 1 on the lowest pallet level accommodated.

As the said figures further show, the cohesion of the loading units 11, 12 and 13 is realized by a strapping band 17 of adjustable length is wrapped around the transport pallet 14, 15, 16 and the uppermost layer of the load 18. To stabilize the loading units 11, 12 and 13 additional end cover 19 are used, which are placed on the uppermost layer of the load 18. <B> reference numerals </ b> 1 Palettiertablar 2 exemption 3 exemption 4 intersection 5 total cargo area 5.1 part loading area 5.2 part loading area 5.3 part loading area 5.4 part loading area 5.5 part loading area 5.6 part loading area 5.7 part loading area 5.8 part loading area 5.9 part loading area 6 border 7 footprint 8th longitudinal web 9 crosspiece 10 intersection 11 charging unit 12 charging unit 13 charging unit 14 pallet 15 pallet 16 pallet 17 strapping 18 load 19 end cover
