Description

Stone Europa Carton Aktiengesellschaft, Spitaler Str. 11, 20095 Hamburg Transport pallet

The invention relates to a transport pallet that can be driven under for receiving loads with an essentially rectangular floor plan made of foldable material such as corrugated cardboard provided in the form of a cut-out, with a pallet surface, with a pallet support surface (lower surface) and with support elements that are spaced apart from one another in the area of the pallet edge and between which at least one loading channel is provided in at least one main dimension of the rectangle for engaging the loading bars of industrial trucks. These are transport pallets that are usually made from rectangular material cut-outs made of corrugated cardboard or similar foldable material. The support/carrying elements such as feet or posts firmly connect the two material surfaces to one another. These elements are also expediently made from corrugated material, whereby it is usual to design them with a standing wave in the support/carrying direction, in particular in the form of full or hollow coils, and to connect them to the multi-layer, high-strength material cut-outs at the front by means of adhesive. The pallets are mostly made with Euro pallet dimensions (800 mm x 1,200 mm; 600 mm x 800 mm).

A transport pallet of this type is known, for example, from EP-A2 0 494 540. In known transport pallets of this type, a flat pallet surface is provided for carrying loads. In many cases, special securing devices such as wedges, strapping or the like are required for transport, in particular to secure relatively light goods and/or goods that have no base or that are not suitable for transport to the pallet. Such securing measures are particularly necessary for transporting loaded pallets by vehicle. Attaching the securing devices takes time and effort, and additional costs are also incurred, particularly for strapping made of high-strength, particularly tear-resistant materials.

The invention is based on the object of improving the securing of the load on the pallet, in particular with regard to cost, labor and time savings, whereby the fastening of a wide variety of goods to the pallet should be particularly simple and reliable.

This task is solved in conjunction with the features of the transport pallet mentioned at the beginning in that the pallet surface has a surface edge that at least partially forms the pallet edge and surrounds at least one delimited receiving space for the load, and the receiving space is provided between the level of the surface edge and the pallet bottom surface, whereby load placed on the pallet partially engages in the receiving space, comes into support against parts of the surface edge and the pallet bottom surface, and at least one loading channel is formed between the support system formed against the pallet bottom surface and the support elements. The receiving space provided according to the invention forms a trough-like, rigid embedding for load. The load comes into support against the pallet surface edge, whereby the surface edge has a supporting and load-bearing function. The edge areas of the pallet are highly strong and can be subjected to force due to the connection of the surface edge to the bottom surface by means of the support-bearing elements such as feet, posts or the like. It is important that the load is supported and carried not only in a force-fitting manner against the pallet base, but also laterally against the pallet edge. As a result of the measures according to the invention, conventional securing means can even be completely eliminated. Any additional strapping, wrapping or the like can be provided much more simply, using less material and at a lower cost.

The opening area of the cargo receiving space is expediently adapted in terms of the opening width particularly to the extremities and/or the external shape of the cargo. In this respect, it is also advantageous and expedient according to the invention to provide several opening areas on the top of the pallet for the receiving space, whereby the edge of the pallet surface

can be equipped with at least one flat intermediate web, which is connected to the pallet underside via support elements.

A particularly useful embodiment of the invention is that the support system for the load against the pallet undersurface is formed by at least one base-like support element that stands rigidly on the pallet undersurface, preferably with several such elements arranged in a row, the height of each support element being smaller than the height of the support elements that space the edge of the pallet from the pallet undersurface and support it. The load comes to rest on the base-like support elements so that it is kept at a distance from the pallet undersurface. The support element or elements are advantageously arranged in a center line of a main dimension of the pallet in order to achieve particularly favorable access with loading beams of industrial trucks. A support system support element can also be located in the area of a loading trough that can be used when the pallet is unloaded.

In a particularly advantageous embodiment of the invention, the pallet surface comprises the surface edge and a material surface surrounded by it with dividing lines, whereby these are preferably parallel in at least one line field, so that material sections are delimited from the surface edge and can be detached from the surface edge to release the receiving space. The pallet surface is thus equipped with pre-punched areas, whereby the arrangement of the dividing line field advantageously allows adaptation to different dimensions of load. A particularly advantageous embodiment of the invention consists in the fact that the dividing sections cannot be completely separated, but are hinged to the pallet surface by means of a folding line, so that at least one folding section is formed, which can be folded towards the pallet bottom surface when the pallet is loaded with load. At least one folding section is advantageously dimensioned so that its edge opposite the hinged folding line comes to lie between the load and the pallet bottom surface or support element. As a result, particularly good force absorption occurs via the folding section and the edge of the pallet surface.

It is particularly advantageous to provide a group of lines in the form of a field of parallel weakening lines that form folding section fold lines. This also achieves a special adaptation of the folding sections to the dimensions of the load part to be placed on the pallet. A plurality of pre-punched folding sections with different sizes can be achieved particularly expediently by folding section fold lines preferably intersecting parallel folding section dividing lines perpendicularly.

A particularly advantageous embodiment of the pallet according to the invention in the design with folding sections consists in the pallet being designed symmetrically to the vertical planes corresponding to the main dimensions of the rectangle, with pairs of folding sections being provided in a symmetrical group or field arrangement, which are preferably hinged so that they can be folded down along a longer side of the rectangle, while the fields of parallel dividing lines are provided on their narrow sides. As a result, the receiving space is V-shaped or trapezoidal in cross section. A centering and positioning receiving trough for the load is formed, which is particularly well suited to receiving at least one horizontal roll of printing paper or similar large rolls. In combination with the fields of dividing lines and/or weakening lines, only material sections corresponding to the roll dimension, i.e. corresponding to the segment length of the circular section of the roll that dips into the pallet receiving space and corresponding to its length, are released on the pallet surface under the considerable weight when it is placed down as an opening area for the receiving space. It should be noted, however, that the pallet according to the invention in every design is not only particularly well suited to transporting rolls, but by providing the pallet surface with adapted pre-punched areas, a large number of other bodies and transport products of different sizes and designs can also be accommodated in a positionally and transportably manner. For example, television sets and motors are just a few examples.

Subclaims are directed to other useful and advantageous embodiments of the invention, and particularly useful and advantageous embodiments or possibilities of the invention are described in more detail in the following description of the embodiments shown in the schematic drawing. They show 5

Fig. 1 when loaded with paper roll.

A transport pallet according to the invention according to Fig. 1 comprises a pallet surface 2 in the form of a cover plate, which is formed by a two-layer corrugated cardboard blank, a pallet base (bottom surface) 3, which is also formed in the form of a plate made of a two-layer corrugated cardboard blank, and eight support elements 4 arranged on the edge of the pallet in the form of hollow feet made of wound corrugated cardboard with a standing wave S. The pallet 1 has a rectangular plan with narrow and long sides. The pallet surface 2 and the pallet bottom surface 3 can also be formed from three- and multi-layer blanks with layers having the same and/or different wave types, whereby the waves of the layers can run parallel and/or crossed.

The support elements 4 are connected in the usual way to the surface 2 and the lower surface 3 by means of adhesive, whereby pairs of tabs 201, 301 provided on the surfaces 2, 3 are folded into the hollow area of each support element. In the illustration according to Fig. 1, the tabs 201, 301 have not yet been removed from the cut surface.

The two main dimensions of the pallet 1 are characterized below by the corresponding center lines 21, 22 of the cutting surfaces 2, 3.

Three support elements 5 are attached to the pallet bottom surface 3. These support elements 5 are arranged in the longitudinal center line 21 with corresponding support elements 4 also located in this line on the two narrow sides of the pallet at equal distances. Like the post support elements 4, the support elements 5 are formed by cuboid-shaped hollow corrugated cardboard rolls. It is important that the height h of the support elements 5 is considerably smaller than the height H of the support elements 4, whereby it is particularly advantageous to select h < H/2. The support elements 5 are also connected to the bottom surface 3 by means of pairs of tabs 301 - not yet shown in Fig. 1 from the blank - in an adhesive connection. In an embodiment of the invention not shown, the support elements 5 can expediently have different heights in order to provide a special adaptation to the contour of the goods being transported.

The support elements 5 arranged in rows form support systems for the load 9 on the upper side, as will be described in more detail in Fig. 3. The load comes to rest with a lower part in a pallet receiving space 10 between the support elements 5 and the upper surface level of the pallet surface 2. The upper surface level of the pallet surface 2 is determined by a surface edge 20 forming the pallet edge. This surrounds the opening area of the receiving space 10.

The design of the pallet surface 2 is shown in more detail in Fig. 2. The blank is provided with pre-punched folding sections 61, 62 and dividing line fields 63, 64 in a symmetrical arrangement to the center lines 21, 22. The two folding sections 61, 62 are each hinged to the long sides of the surface edge 20 by means of a perforation line 71. In the areas of the narrow sides, the folding sections 61, 62 are limited by the parallel dividing lines 82 of the dividing line fields 63, 64. The free edges 600 of the folding sections 61, 62 opposite the hinged folding lines 71 are cut free outside the line fields 63, 64 with a longitudinal cutting line 81, while the

extension of this cutting line 81 into the fields 63, 64 is formed by dividing lines 83. These dividing lines 83 are cutting line sections interrupted by material webs, whereby the material webs are formed by the strip surfaces 65 parallel to the dividing lines 82 between these lines 82 and the cutting line sections of the line 83 cross the cutting lines of the dividing lines 82. This is shown in more detail in detail D.

Within the scope of the invention, it can be advantageous and expedient to provide the material section 6 with punched-outs (not shown) that are adapted to partial contours of the load. For example, parts of the dividing lines 81, 83 could also be provided as flat punched-outs. In an advantageous design, the surface edge 20 can be connected to a web surface 200 that is at the same level as the surface edge 20. Such a web, which can expediently be connected to the pallet bottom surface via additional support elements 5, is shown in dashed lines in Fig. 2.

The cutting lines of the dividing lines 82 are of equal length and are equally separated and at the same distance by material webs 820. This creates folding strips 73 of the weakening lines 72 parallel to the perforation lines 71. These are also determined by the alignment of the horizontal wave W of the cut of the pallet surface 2. Folding lines are thus formed with which each flap 61, 62 is divided into four folding strips 67.1 to 67.4 parallel to the folding lines 71. The width of these folding strips corresponds to the length of the cutting line sections of the dividing lines 82.

It can be seen that the material surface 6 of the pallet surface 2 surrounded by the surface edge 20 is divided into a group of pre-punched, separable or foldable surface sections in that a group of folding lines 7 is provided parallel to the one center line 21, while the parallel separation lines 82 are formed perpendicular to this. This ensures that only one individual opening area is created, adapted to the contour of the lower part of the load 9, through which the load 9 engages in the receiving space 10. For example, in Fig. 2, the dashed line 90 shows the contour of a lying roll to be transported in the area where it is enclosed in the pallet 1.

It is evident that when such a relatively heavy roll is placed along the dividing lines 82, the narrow edges of the flaps 61, 62 are created by breaking the webs 820, whereby these fold down in strips in stages with the weakening lines 72.

The position of a roll 9 with end faces lying on the narrow sides of the pallet is shown in more detail in Fig. 3. It is clear that the lying roll is enclosed in the material of the surface 2 with its segment section determined by the segment width a. In this case, a force is introduced into parts of the surface edge 20 via the material parts of the material surface 6, and the roll is held in a stable position and non-slip. This is particularly helped by the measure that the folding sections 61, 62 are dimensioned in such a way that their free edges 600 or strips 67.4 come to rest on the surface of the support elements 5 when folded down, i.e. they come to rest between these and the roll 9, squeezing under the weight of the roll. In this respect, these edge surfaces 600 form support systems between the load 9 and the support elements 5.

Instead of one roll 9, two rolls with the same or different diameters can be placed one after the other on the pallet 1. In Fig. 3, a further roll 9 with an even larger diameter is shown in dashed lines, which is safely picked up by the pallet 1 by breaking out and bending the corresponding material parts.

As can be seen in particular from Fig. 3, the unit consisting of pallet 1 and roll(s) 9 can be conveniently transported using industrial trucks such as forklifts. Loading beams of a forklift (not shown) engage in the longitudinally extending loading grooves 11 formed between the outer support elements 4 and the row of support elements 5 and, in this state, lift the combination of pallet 1 and roll 9. This is achieved by the fact that the material sections of the flaps 61, 62 that support the load 9 are located between the roll 9 and the loading beams. When transported using a forklift, the load 9 does not change its position in relation to the pallet 1 or does not change it significantly.

As can be seen in particular from Fig. 1, it is also possible to drive under the unloaded pallet 1 from the long side with loading beams of industrial trucks. The two outer support elements 5 are arranged in the area of loading channels 12 (Fig. 2) between support elements 4. Due to the significantly lower height h of the support elements 5 compared to the height H of the support elements 4, loading beams can easily reach through the area between the surface 2, which is flat in the unloaded pallet state, and the support elements 5.

When the pallet 1 is loaded with a roll 9, it can be removed particularly easily at the destination of the pallet transport, e.g. in front of a printing machine, due to the pallet 1 designed according to the invention. For this purpose, the middle foot support element 40 is knocked away on one long side of the loaded pallet, as shown in dashed lines in Fig. 2, whereby the pallet edge 20 can be lifted in this area using an industrial truck if necessary. The surface edge 20 is then torn off in the web areas 14 due to the weight of the roll 9 rolling off the pallet 1. The rolling off of the roll is facilitated by the inclined surface 68, which then extends from the support elements 5 to the bottom surface of the pallet, as shown in dashed lines in Fig. 3.
