Description

Arrangement of two load carriers on each other

The invention initially relates to an arrangement of a first load carrier in the form of a pallet

with a cargo table which has a cargo area for a load on its upper side,

with runners, which are arranged on the underside of the goods store,

- With first contours, which are formed on the top of the Ladeguttisches,

with second contours, which are arranged in a footprint of the skids,

wherein the first and second contours are formed at least partially complementary shape and arrangement, so that when first sitting two similar pallets the first contours of the first pallet engage in the second contours of the second pallet for securing cargo,

and a second load carrier in the form of a - possibly collapsible - crate

with two opposite end walls, two opposite side walls and a floor, which together form a cargo receiving space,

with third contours formed by free edges of the front and side walls,

with fourth contours, which are formed from the bottom of the box on the side of the box facing away from the load receiving space,

wherein the third and fourth contours are at least partially formed shape and arrangement complementary, so that when sitting two similar boxes the third Contours of the first box in the fourth contours of the second box to secure cargo.

From the prior art, cargo carriers in the form of pallets are initially well known. A large part of the circulating pallets are used as reusable pallets and are used several times for the transport of goods. It may happen at transport destinations that accumulate larger amounts of reusable pallets, because the amount of goods received exceeds the amount of shipped goods. Since the reusable pallets have a sufficiently high value due to a deposit system or due to the design of the logistics chain, excess pallets are regularly returned to central distribution points. In order to simplify the load securing during the return transport of reusable pallets to distribution centers, it is known from the prior art to provide the footprints of the runners and portions of the top of the Ladeguttisches the pallets with interlocking contours, which are also called stack contours. These make it possible to stack pallets of the same type in a non-slip manner. This is known, for example, from EP 2 380 817 B1, which shows nested palettes. In addition, reference should be made to EP 1 076 01 1 B1, in which the surface of the cargo compartment has depressions into which projections of the runners can engage.

From the prior art, it is also known to use boxes as carriers and also to use them in a reusable system, that is, with the return of empty boxes. It is well known from the prior art document which can not be documented that stack contours should also be provided for cases. For this purpose, the crate bottom usually has a circumferential recess on the underside, the recording of the opening edge of a underlying box serves. In this way, boxes can sit on each other slip-proof.

It is also known to make such transport crates foldable or hinged. In an erected state, these transport crates - summarized under the generic term "collapsible transport crate" - provide a receiving space for goods and goods of all kinds After emptying the crate, it is possible to fold the side walls into a box bottom parallel position and thus reduce the crate volume.

Such transport crates are also used in a reusable system, whereby here - as described above for pallets - in places of goods acceptance usually a box surplus arises because the goods delivery is reduced compared to the goods receiving or does not matter. Similar to pallets, however, these reusable boxes have a certain value, so that they are regularly recycled to distribution centers. Here, too, the intervention of the box bottom into the underlying box opening in the sense of a stack contour for securing the load is utilized. In the case of collapsible boxes, it is also customary that the outer surfaces of the crate floor in the folded state side walls form a compatible with the bottom of the box arranged above edge in the sense of a stack contour. In this way, folded boxes can also be stacked and transported without slipping. It is an object of the invention to further improve the return of reusable pallets and reusable boxes. The object of the invention is achieved by an arrangement of load carriers according to claim 1, in particular with the characterizing features, according to which the first contours of the pallet are formed with the fourth contours of the box at least partially form and arrangement complementary, and the second contours of the pallet with the third contours the box and the second contours of the pallet are formed at least partially shape and arrangement complementary, so that interlock contours for securing cargo when placing the box bottom on the cargo surface of the pallet and interlock contours for securing cargo when placing pallets on boxes.

The main advantage of the invention is thus that different Lagegutträger - here pallet and box - have mutually compatible stack contours. Thus, it is possible that for returning the Lagegutträger mixed stacks can be formed, which are non-slip supported on the intermeshing contours. This has not only for the return of the load carrier considerable advantages, but for the transport in general. It is not uncommon that goods containers - consisting of a pallet with the goods stored thereon - not only next to each other on a transport vehicle but also one above the other are arranged. Now, if the goods are packed in reusable boxes, and these reusable boxes are arranged according to the invention on a pallet to a container, can be placed on the upper box level of a first goods package a second goods package, the contours of the runners of the pallet of the second goods package in the engage corresponding contours of the underlying box level. In this way, several product packages can be stacked one above the other slip-proof. It is of considerable advantage if the load surface of the pallet and the base of the box are matched to one another such that a number of boxes substantially completely fills the load surface of the pallet.

In this way, compact stack of boxes and pallets can be made, which are transportable volume optimized.

It is further provided that the third contour of the box from the free, the cargo receiving space bounding edge of the end and side walls is formed.

Furthermore, it is envisaged that the third contours are formed when using a collapsible box from the outer surfaces of those side walls, which are arranged crate bottom remote in the folded state.

The invention further relates to a load carrier in the form of a pallet, with a loading table whose upper side forms a load surface for the load,

with runners, which are arranged on the underside of the loading table and on which the load table sits at a distance from a footprint,

with a first contour formed on the top of the cargo door,

with a second contour, which is incorporated in the footprint of the skids,

wherein the first and second contour are formed at least partially complementary to each other and complementary arrangement, so that when stacking similar pallets on each other, the first contours on the top of Ladeguttisches a first pallet in the second contours of the footprint of the runners of a second pallet engage.

The invention is achieved by a charge carrier in the form of a pallet with the features of claim 5, in particular with its characterizing features, according to which the first contour is formed as a relation to the load surface applying web, the web forms a peripheral edge surrounding the Ladeguttisch, the second Contour is formed as an opposite the footprint of the blade retracted depression.

The essential advantage of the pallet formed according to the invention lies initially in the web surrounding the positional table, which forms a peripheral edge. This circumferential edge has first in interaction with the fourth contour, which is formed by the above-described box, the significant advantage of forming a secure stack contour. At this, the corresponding stacking contour of a box can be supported over a large area, so that the box, or possibly more boxes are kept non-slip on the pallet.

In addition, several similar pallets can be stacked on top of each other in interaction with the second contour formed on the side of the chute, in which case the first contour and the second contour also engage in a large area in a stack and thus ensure a particularly high level of slip resistance during transport.

Compared to other stack contours from the prior art, whether positive versus the load table, that is, applying trained contours, or negative, that is opposite the surface of the Ladeguttisches retracted contours, the inventively designed first contour has a further significant advantage. Since it is circumferential and in a particularly preferred embodiment Furthermore, characterized in that the first contour next to the circumferential ridge comprises a Ladegutfläche at least dividing gutter whose Ladeguttischparallel width corresponds approximately to twice the width of the circumferential ridge, the range can be used without restrictions for cargo, which does not have the first contour having corresponding mating contours.

Other cargo, such as cartonnages, are in the area of the first contour over the entire surface and can be pushed off the pallet without any problem, whereas in the prior art due to only partially contoured contours - especially if they are formed as positive contours - the risk of entanglement the stack contour exists. In a further advantageous embodiment, it is provided that the loading table carries on its underside at least two juxtaposed, outer runners, wherein the second contours of these outer runners correspond to the peripheral web. It is further provided that between the outer runners at least one center runner is arranged, whose second contour corresponds to the gutter.

A better understanding of the invention and further advantages thereof will become apparent from the following description of an embodiment. Show it:

In Fig. 1, an arrangement of different Lagegutträger is generally designated by the reference numeral 10.

The arrangement 10 consists of successively placed pallets 1 1 and boxes 12. As can be seen in Fig. 1, both pallets 1 1 are placed on each other, and boxes 12 are placed on each other. In addition, boxes 12 are placed on pallets 1 1 and pallets 1 1 placed on boxes 12.

The boxes 12 are matched in size to the size of the pallets 1 1. In the present example, the base of each box 12 is about a quarter of the base of a pallet 1 1, so that 4 boxes 12 on a pallet 1 1 can be arranged. Fig. 6 shows a pallet 1 1, as it is used in the arrangement 10 of FIG. The pallet 1 1 has a Ladeguttisch 13, which is provided on its underside with skids 14. In the present example, 13 runners 14 are arranged on the underside of the Ladeguttisches 13, wherein the edge-side runners 14 are also referred to as outer runners 15 and the intermediate runner is also named as the center runner 16.

The Ladeguttisch 13 forms on its upper side a load surface 17, on which the load is placed. In the present case, the load surface 17 is separated into two partial surfaces 17a and 17b. Furthermore, the loading table 13 forms a first contour designated as a whole by 18, which is formed by a web 19 surrounding the load surface 17. Part of the first contour 18 in the embodiment is also an intermediate web 20 which separates the load surface 17 in its partial surfaces 17a and 17b. The intermediate web 20 is optional and not mandatory for the function of the invention. The intermediate web 20 separates the load surface 17 into two equal parts of the load parts 17a and 17b. It should also be noted that the first contour with web 19 and intermediate web 20 is a positive contour with respect to the load surface. That is, the contour protrudes over the load surface in the sense of a material order. Further, in the illustrated embodiment, the intermediate web 20 is disposed above the center skid 16, directed to this direction parallel and has approximately twice the width of the circumferential ridge 19.

Just for the sake of completeness, strapping grooves 21 are already mentioned at this point, which are arranged on the underside of the loading gantry 13 between the runners 14 or in the area of runner-free cutouts 22. They will be described later in function and structure. Fig. 4 shows a view of the pallet 1 1 of FIG. 6 from below. The runners 14 are turned with their undersides to the viewer. The undersides of the skids 14 initially form a footprint 24 as part of a riot element 39 and against the footprint 24 retracted recesses 23 from. The footprint 24 and the respective depression 23 are accordingly located with respect to footprint in two different height levels. In this way, the undersides of the skids form a second contour 25, which is at least partially contour and position complementary to the first contour 18 formed. Those areas in which the second contour 25 are formed complementary to the first contour 18 are designated 26 in FIG. 4. In these areas, the webs 19 and 20 of the pallet upper side adjoin the side walls 27 of the uprising element 39 that are formed by the depressions 23. In this way, stacked pallets 1 1 imposed a defined relative position to each other and beyond a slipping stacked pallets 1 1 prevents. The sloping portions of the side walls 27 are used for self-positioning of the pallets 1 1 during the stacking process, especially when pushing an upper pallet on a lower pallet by zwangspositionieren in non-exact alignment of the pallets 1 1 selbige to complementary engagement of the contours 18 and 25 ,

FIGS. 7 and 8 now show a second load carrier in the form of a box 12, which is shown in FIG. 7 in a perspective view of the box opening 28 and in FIG. 8 in a perspective view of the box bottom 29. In addition to the box bottom 29, the box 12 has opposite end walls 30 and also opposite side walls 31, which together with the box bottom 29 form a receiving space for goods. The box opening 28 bounding the free edges of the end and side walls 30, 31 form - as a bridge - a third contour 32 from. Of the Box bottom 29 is provided with an outer peripheral circumferential retraction 33, through which the box bottom 29 forms a fourth contour 34. This fourth contour 34 is complementary in shape and arrangement to the third contour 32, so that when stacking boxes 12 on each other, the free end portions of the end and side walls 30, 31 in the region of the withdrawal 33 to the arrangement. In this way, the box bottom 29 engages as it were in the opening 28 of the underlying box 12, so that a plurality of boxes 12 can be stacked on each other positionally and non-slip.

To allow a mixed arrangement of pallets 1 1 and boxes 12 of FIG. 1 in the context of the invention, the first contours 18 of each pallet 1 1 with the fourth contours 34 of each box 12 at least partially formed form and arrangement complementary, so when placing the box bottom 29 on the load surface 17 of the pallet mesh both contours. In addition, the second contours 25 of the pallet 1 1 to the third contours 32 of the box 12 at least partially formed shape and arrangement complementary, so when placing a pallet 1 1 on boxes 12, the second contours 25 for securing cargo in the third contours 32 engage.

This state is in the sectional view of an arrangement according to the invention shown in FIG. 2 shown. There is a pallet 1 1 placed on an array of boxes 12. On the pallet 1 1 turn boxes 12 are arranged. As can be seen from FIG. 2, the second contours 25 formed by the lower sides of the skids 14 engage in the third contours 32 formed by the box walls 30, 31. In fact, it is the case that the recessed surfaces 23 come to rest on the upper sides 35 of the side walls 30, 31 and the rearing elements 39 engage in the box opening 28. In this way, the pallet 1 1 sits correctly and non-slip on the lower box layer 12. The pallet 1 1 in turn now carries an upper box layer, in which case the first contour 18 of the pallet 1 1 engages in the fourth contour 34 of the boxes 12. This is done by the webs 19 and 20 engage in the withdrawals 33. In this way, the boxes 12 of the upper box layer are arranged non-slip and correct position on the load surface 17 or on the cargo side surfaces 17a and 17b of the pallet 11. Thus, the formation of complementary stack contours 18, 25, 32 and 34 not only allows boxes 12 on boxes 12 and pallets 1 1 on pallets 1 1 slip and position safe to arrange each other, but also mixed arrangements of pallets 1 1 and boxes 12 to form , which are also aligned slip and correct position to each other.

Fig. 3 shows an alternative arrangement 10 of pallets 1 1 and boxes 12. The boxes 12 shown there are collapsible boxes 12, in which in the unused state, the front and side walls 30, 31 can be arranged crate ground parallel. In this way, the box volume is reduced considerably. In the present case, the third contour 32 is formed by the outer sides of the end or side walls 30, 31 facing up in the folded state. For this purpose, in the present example of Fig. 3, the side walls 31 via a collar 36 which rests against the outer wall surface. In this way, formed between the collar members 36 of the side walls 31 a recess in which the uprising elements 39 can be seated, so that here an interaction of the third contour 32 with the second contour 25 of the pallet skids 14 a correct position and slip-proof seating the pallet on a together Box 12 is guaranteed. Finally, with reference to FIG. 5, the aforementioned Umreifungsnut 21 will be explained in more detail. FIG. 5 shows an enlarged detail with a perspective view of the underside of the pallet. As shown, points the pallet edge on a groove-like indentation, which forms the Umreifungsnut 21. If the load is secured by means of strapping bands on the pallet 1 1 to secure the load, the strapping groove 21 initially ensures a defined position of the strapping band. This favors a secure attachment considerably.

As shown in FIG. 5 embodiment, the Ladeguttisch 13 is not made of solid material, but for the purpose of weight saving, a structure of individual ribs 37, 21 support webs 38 are arranged between two adjacent ribs 37 in the Umreifungsnut. These prevent a strap when tightening the outer rib 37 of the pallet 1 1 damaged.

In summary, a pallet 1 1 was presented with stacking contours and a box 12 with stack contours, the stack contours of pallet 1 1 and box 12 are mutually formed at least partially form and arrangement complementary. This is made possible by pallets

1 1 and boxes 12 with interlocking stack contours to each other, so that stable stacks arise in which the individual components are mutually secured against slipping.

As mentioned above, the stack contour of the pallet 1 1 in the form of the circumferential web 19, if necessary using the intermediate web 20 has the significant advantage of delaying even load, which is not packed in boxes 12. Hooking the load is made difficult by the peripheral edge.

This advantage can be increased if on a pallet 1 1 and a box

12 is used according to the figures 9 and 10. A portion of the cargo surface 17 or the cargo side surfaces 17a and 17b at least one of the first contour 18 spaced plateau 40 forms, which opposite the load surface 17, 17a, 17b applies. On this one or the plurality of plateaus, the load is on, so that the height of the first contour 18 - the circumferential ridge 19 - is reduced relative to the bearing surface of the load. The at least one plateau 40, which forms the bearing surface for goods not packed in boxes 12 according to the invention, has a reduced height with respect to the first contour 18. In this way, it is ensured that the first contour 18 protrudes in height with respect to the bearing surface formed by the plateau 40, ie is a positive contour in this sense. At the same time the pushing and pushing of load is facilitated, which is not packed in boxes 12 according to the invention.

It is provided that between the first contour 18 and the at least one plateau 40, a groove-like recess 41 is arranged. The bottom of this recess 41 is formed by the load surface 17. The box 12 to be used for this embodiment accordingly forms a third contour 32 in the form of a spring 42 protruding from the box bottom 29. This engages in the groove-like recess 41 and rests on the load surface 17. The favorable for the non-slip arrangement of the box according to the invention height of the first contour 18 thus remains despite plateau 40 obtained.

Based on Fig. 1 1 it is shown that, taking into account the pallet base box 12 different size on the pallet 1 1 can be stored using the stack contours. This is indicated by the different dashed lines.

In a specific embodiment, a pallet size of 800mm x 600mm is provided. For this, boxes 12 of 600mm x 400mm or 300mm x 400mm can be used. The first contour 18 of the pallet 12 - formed by the circumferential ridge 19 and possibly the intermediate web 20 should have a height of 4mm on the load surface 17, that possibly existing plateau meadow then a height of 2mm.
