Pallet, method for loading it with goods placed in a packaging and method for stacking such loaded pallets.

The invention relates to a pallet, comprising a supporting layer, a supporting layer and an intermediate layer spaced and connecting the two layers, which is spaced between them.

A pallet of the above type is known. This known pallet is made of wood and is therefore heavy.

The object of the invention is to provide a pallet which, on the one hand, is strong as well as lightweight and, on the other hand, can be manufactured at such a low cost that the pallet can also be used as a single pallet 10 to be shipped.

This is achieved with the pallet according to the invention in that the intermediate layer is built up of profiles extending between the supporting layer and the supporting layer and connected thereto, a number of which make an oblique angle with the two layers and each transverse to the side surface of the pallet or because at least one of the layers kept at a distance and connected by the intermediate layer consists of a grid formed by profiled metal grid elements.

A one-off pallet to be shipped is known. This known pallet can also be manufactured at a low cost, because inexpensive materials such as pressed cardboard and the like are used for the manufacture of this pallet. A drawback of this pallet made of cheaper materials is that during loading or unloading of the pallet 25 it can go into ruin. Before further transport is possible, the goods must first be loaded onto a new pallet. This can lead to significant delays in transport and associated additional transport costs.

The invention also provides a method for loading a pallet constructed from a carrier layer, a supporting layer and an intermediate layer arranged between the two layers, which separates and connects the two layers, with goods placed at a mutual spacing.

In the event that the pallet is loaded with goods placed at a mutual spacing in slack packaging, it is necessary to use a pallet provided with a practically closed carrier layer.

According to the method of the invention it is possible to load a pallet provided with a carrying grid with goods placed at a mutual spacing in slack packaging. This is achieved in that a pallet is used, the carrier layer of which is built up from a carrier grid formed by grid elements 15 and a distance e between two of the grid elements forming the carrier grid is a small multiple of the pitch distance f, and the packaging such on the carrier grid is placed so that rows of the spaced-apart goods in in the package are superimposed on different grid elements.

The invention also provides a method for stacking a carrier layer, a supporting layer and a pallet arranged between the supporting layers, which separates and connects the two layers, and which are loaded with at least one goods containing spaced-apart spacing. -

Such pallets, when loaded with goods placed in a slack packaging, can only be stacked if the supporting layer is in the form of a flat plate, so that the weight of the loaded pallet over a large number of the goods placed in the slack packaging. goods are supported.

According to the method of the present invention, it is possible to stack a loaded pallet provided with a support grid on the goods placed in the slack packaging from the pallet below, by using pallets whose support layer consists of a grid elements formed support grid is built up and a distance £ between 8202248 /

Mentioned and other features will be elucidated on the basis of a drawing.

In the drawing, figures 1 and 2 represent a perspective top and bottom view of a pallet according to the invention; figure 3 on a larger scale detail III from figure 1; figure 4 shows detail IV from figure 2 on a larger scale; Figure 5 shows a larger section along the line V-V from figure 1; figure 6 shows a schematic representation of a pallet according to the invention loaded with goods placed at a mutual pitch distance f in a packaging; Fig. 7 shows a schematic representation of the stacking of a pallet on goods placed in packaging with spacing spaced apart by applying the method according to the invention. and figure 8 shows a view along the line VIII-VIII from figure 7.

The pallet 1 according to the invention comprises a supporting layer 2, a supporting layer 3 and an intermediate layer 4 spaced between the two layers 2 and 3 and connecting between them (Figures 1 and 2).

The intermediate layer 4 is built up of profiles 5 extending between the supporting layer 2 and the supporting layer 3 and connected thereto. A number of the profiles 5, the profiles 5a, make an oblique angle with the two layers 2 and 3 (33,34 ) and are transverse to a side surface 6, 7 of the pallet 1. Apart from the two grating elements 5a ', the profiles 5a form pairs which are mirror symmetrical in a plane perpendicular to the side surface 6, 7 of the pallet 1 from each other. Profiles 5a 'are not in one and the same plane. The other profiles 5b of the intermediate layer 4 are perpendicular to the supporting layer 2 and the supporting layer 3.

The support layer 2 and the support layer 3 are each made up of a support grid 11 and support grid 12 formed by profiled metal grid elements 9, 10 respectively.

The grating elements 9 and 10 and the profiles 5 consist of profiles folded from sheet material, which are preferably U-shaped. The height β of the flanges 13 of the U-profiles is substantially equal to half the width d of the body 14 of the U-profiles.

The support surface 21 of the support grid 11 is bounded by the flanges 13a of the support grid elements 9a and by the webs 14c of the support grid elements 9b (figure 5). The shelf grid element 9b crosses the shelf grid element 9c at a right angle, at the level of the profile 5b. One end 18 of the support grid element 9c is surrounded by 15 the support grid element 9a, the body 14 of which is perpendicular to the support surface 21.

The support surface 20 of the support grid 12 is formed by the grid elements 10 and corner pieces 15 are provided in each corner 8 of the support grid 12 (figure 4).

At a connection 16 (figure 3) between a terminating support grate element 10a and a continuous support grate element 10b, each of which are ü-profile-shaped and lie in the support surface 20, a flange 13b is of the continuous grate element 10b towards the plane 20 of the body 14b of this grating element 10b 25 is thus bent that the grating elements 10a and 10b lie substantially in one and the same plane.

The surface area van of the supporting layer 3 is smaller than the area Id of the supporting layer 2.

The sheet material has a thickness of 0.7 - 0.8 mm, preferably 0.75 mm. The height c of the flanges 13 of the u-profiles 5,9,10 is preferably 7 mm and the width <3 of the body 14 of the u-profiles 5,9,10 is preferably 15 mm. The weight of the pallet 1 is approximately 3 kg. The maximum static load is 3.5 tons.

The grating elements 9, 10, the profiles 5 and the corner pieces 15 are firmly connected to each other by spot welds 24 arranged with a welding machine.

Figure 6 schematically shows a pallet 1 loaded with packaging 25, shown with dash-dot lines, at 40 8 2 0 2 2 4 8 * '. Goods placed at mutual pitch distance 26. The distance e between two of the grid elements 9a, 9b forming the bearing surface 21 of the support grid 11 is a small multiple of the pitch distance £. The crosses 29 indicate the centerline of the goods 26. The packs 25 are placed on the support surface 21 of the support grid 11 such that rows 27, 28 of the stack. spaced apart goods 26 are placed on top of different grating elements 9 forming the support surface 21 of the support grid 11.

Figure 7 schematically shows a pallet 1, which is placed on the packaging 25 with its support surface 20 consisting of the support grid 10 and the corner pieces 15. The distance tussen between two grate elements 10a forming the support grid 12 is a small multiple of the pitch distance van of the goods placed in the package 15. The pallet 1 is placed on the package 25 such that the grid elements 10 forming the support grid 12 stand on top of rows 30,31 of the goods placed at mutual pitch in the package 25.

Figure 8 shows two pallets 1, each of which is loaded with packages 25 containing goods 26 placed at mutual pitch distance. The pallet 1a is placed on the packaging 25 of the pallet 1b below it such that the weight of the loaded pallet 1a is supported on the ground 32 via the goods 26 placed on the pallet 1b in packaging 25 and via the pallet 1b. This manner of stacking is possible because the distance tussen between two grating elements 10 forming the support grate 12 is a small multiple of the pitch distance f.
