Description

DESCRIPTION

Large load support

The invention relates to a support for large loads for receiving and transporting industrial goods, merchandise, goods in bales and the like, according to the preamble of claim 1.

Until now, especially for the transport of goods in bales or pallets, Europool pallets or Europallets are used, which generally exist in standardized sizes and are formed by a flat pallet platform to receive the goods in bales and support feet or support skates on the bottom side. The disadvantage of these pallets is that due to the lack of lateral delimitation walls, special fixing measures are required for the transport of goods in loose bales.

Therefore, to transport goods in loose bales, large load supports are provided, with generally folding side walls, that is, they are structured as containers. Large load carriers of this type that are also called large containers typically have dimensions of 800 x 600 mm and more, especially approx. 1200 x 800 mm, 1200 x 1000 mm and 1200 x 1600 mm, in the case of standard dimensions. The height of this type of large load carriers depends on the desired load capacity. A usual height calculated from the installation surface of the support of large loads on the floor to the upper edge of the side walls measures 1000 mm, although this is not limiting. twenty

There is therefore a definition of the support of large loads compared to other smaller containers such as containers of fruits and vegetables or boxes of bottles and the like that can be stacked in several layers one on top and next to others on pallets.

 25

The supports of large loads that are generally manufactured from synthetic material are used to receive goods in bales and are often also used for the transport of large-volume objects in the industrial field, especially for supplies of parts in the automobile sector, but also the food sector. Large load carriers of this type are bulky and, in comparison to the usual fruit and vegetable containers, they are designed with a greater thickness being heavier as a whole, so that the transport of full load carriers generally can only be performed mechanically, especially by forklifts and the like.

In addition, frequently, large load carriers are provided with a cover that prevents the fall of industrial goods or transported goods and protects them, for example, against moisture, water or dirt. Frequently, the covers of this type of large load carriers are connected through connecting elements to one or several side walls of the receiving body, so that together it results in a closed packing unit. The connecting elements of this type are, for example, plug-in or threaded-joint pieces, elastic fitting devices, clamping joints or the like.

 40

Large load carriers such as those disclosed for example by US2003 / 0102309A1 are formed by an inner side wall and an outer side wall between which continuous hollow spaces or several separate hollow spaces are arranged.

However, in addition to making available a closed packing unit, it is also often a matter of securing the transported good against the unauthorized opening, with the possibility of subsequently detecting the unauthorized opening of the lid.

The containers of synthetic material that present this type of security elements are known by the state of the art. Document EP1857375B1 discloses a container closure that allows a seal 50 to be arranged in a closure flap to secure the container against unwanted opening. After closing the lid, the seal can be introduced in a through hole of a closing flap disposed in the marginal area of the container and in a through hole provided in a base body. Since the closing flap has a gear core that engages in a hole of a locking flap disposed in the lid of the container, the lid is locked with the container and additionally secured against unauthorized opening by means of the seal. A similar solution is also presented in patent specification AT339200.

Document DE102004019322 also disclosed a mail container with a removable cover that has a seal insurance that can be burst. For the seal safety, the lid and the container preferably have to be provided with holes in which a corresponding pivot 60 of the seal can be inserted. Also by document EP0957037A2 a seal hole was disclosed in

a side wall and also in WO2009 / 153694 cavities are described both in the cover and in the side wall, intended to receive a seal cord, a seal tape or a plug-in seal.

Generally, large containers are manufactured industrially without prefabricated seal holes, so that they can be used universally. Therefore, the seal holes are subsequently made 5 by means of corresponding holes in the side walls and in the covers. Since, generally, the side walls are double-walled, that is, they enclose hollow spaces, through this type of holes, for example, water from outside can enter the hollow space during cleaning of reusable large load supports. This is highly undesirable, all the more so that the weight of the container increases accordingly. On the other hand, it is very difficult and complicated to remove the water that has entered through the small hole afterwards from the hollow space.

Therefore, the present invention has the objective of providing a support for large loads of synthetic material that can be modified in a simple and advantageous way to make a seal, but without this modification leading to the unwanted entry for example of water from cleaning in the hollow spaces of the 15 support of large loads.

According to the invention, this objective is achieved by means of the characteristics contained in the characterizing part of claim 1, the convenient variants of the invention being characterized by the characteristics indicated in the dependent claims. twenty

According to the invention, the support of large loads has at least one of the double-walled side walls specially manufactured in sandwich process at least one seal mark visible from outside. Said seal mark is used to apply a drill bit to make a seal hole in the right place. The at least one seal mark is made in such a way that it faces towards a chamber opposite the hollow space of the double wall side wall, whose hollow space is minimized, especially presenting a maximum extension of the hollow space of only a few cm, approx. <10 cm, <8 cm, especially <6 cm, so that due to the very small volume of the chamber, the entry of water, especially washing water through the drill, is negligible. The advantage offers the advantage that on the one hand a drill point is made available through the mark and, according to the intended use and the required safety, a 30-hole orifice of seal can be drilled leading to a separate chamber in the hollow space of the side walls made with double wall by injection. In this way, after drilling, a seal can be introduced through the seal passage hole. In addition, the seal mark also indicates the point to also drill the chamber located behind and prevents the side wall from being drilled at any other point, for example damaging one of the connecting ribs. Another advantage is that the chamber disposed separately from the hollow space has a small volume in proportion to the other hollow spaces of the side walls. The water that during the cleaning of the support of large loads until now entered the hollow or spaces of the support of large double-walled loads through the passage hole of seal in the piece the outer side wall is now collected in the chamber with a limited hollow space, ie minimized, so that the remaining hollow space is not affected. At most, a very small volume of water can be received in the chamber and the weight change of the large load carrier is negligible compared to a remaining hollow space filled with water from the load carrier. The chamber volume is advantageously conceived for a narrow limitation of the drilled hole, preferably being approximately equal or only insignificantly larger than the bore volume.

 Four. Five

In a special embodiment, the chamber to which the seal passage orifice leads is disposed in the hollow space separately from the ribs that join the double-walled side walls and is formed by soul-shaped delimitation ribs that bridge the hollow space and that extend horizontally and / or vertically. Said delimitation ribs may be made separately and not be part of the joining or reinforcement ribs, through which the inner side wall piece is welded to the outer side wall piece. The proportion of the size of the separated chamber with respect to the hollow space or to the different hollow spaces formed by vertical joining ribs that extend along the height of the side wall is conveniently at least 1: 8. In the case of a hole in the seal mark of the large load carrier, it is drilled in said separate chamber. The soul-shaped ribs that delimit the chamber extend from the inner side of the outer side wall piece to the outer side of the inner side wall piece 55 and seal the chamber with respect to the adjacent hollow spaces. The thickness of said chamber delimitation ribs that are made especially in the form of souls may vary according to the weight of the load.

In an alternative embodiment, the chamber can also be delimited by the horizontal delimitation ribs 60 and a partial area of the vertical junction ribs. The vertical joining or reinforcing ribs generally extend along the height of the double-walled side wall of the large load bearing and,

In this special embodiment, the vertical delimitation nerves of the chamber are composed of a partial section of said junction nerves.

The shape of the chamber can be made individually, especially the chamber is made in a circular or rectangular shape seen in plan or in cross-section. The seal mark that is visible from the outside is preferably arranged at the top edge of the container, especially in the corner area of the large load carrier. The seal mark according to the invention is provided easily located on at least one side wall. If all the outer sides of the double-walled side walls have seal marks of this type, they are arranged in the support of large loads so that they can be easily recognized from any direction. 10

If connection ribs are provided, joined together by welding, joining the outer side wall piece with the inner side wall piece of the double wall side wall, the seal mark is arranged at a maximum distance of 3 to 30 mm, 3 to 20 mm, preferably 5 to 10 mm, with respect to the junction ribs arranged in the hollow space. This separation is also applicable for the distance of the seal mark with respect to the delimitation ribs of the separated chamber. This separation offers the advantage that when drilling the wall piece by the seal mark, the nerves that delimit the chamber and the junction ribs between the outer and inner side wall pieces are not drilled, for example if the drill is applied obliquely or if it slides a bit laterally when drilling. In addition, this distance with respect to the junction ribs or delimitation ribs is necessary because the diameter of the hole is already between 5 and 8 mm, especially 6 to 20 mm, preferably 8 mm.

In another embodiment of the support of large loads a seal mark is provided located on the side of the cover which is provided on the cover that can be removed or which is arranged on the support of large loads by means of joining elements. If a mark is arranged on the side of the container, the mark located on the side of the lid is oriented towards the seal mark located on the side of the container. Therefore, it can be sealed not only from the wall side of the load carrier, but alternatively also from the side of the lid. In addition, a seal wire, a passage seal or the like can be passed through the hole in the outer wall piece inside the chamber leaving it through the hole located on the side of the cover, or well, in the opposite direction, through the hole located on the side of the cover through the chamber and the hole in the outer wall piece. The seal material can be made of synthetic material or metal and can also have a metal alloy. This type of seal pins can also be plastically deformable and have a sealing tag or the like. In addition, this type of labels that can be arranged on the support of large loads can also present an RFID identification or other technical solutions for digital identification, with merchandise data being stored in transported bales or transported goods 35, the place of destination or similar data. Therefore, the support of large loads can be secured against unauthorized opening by means of lead seals, express lead seals, synthetic seals, express synthetic seals, spike seals, aluminum seals, synthetic seals , plug-in seals, passage seals, container seals or similar seals.

 40

In another embodiment, a seal mark is provided on the upper edge of the double wall side wall, so that a seal passage hole can be drilled in the double wall side wall not only from the side but also from above. Preferably, said seal mark is arranged perpendicularly below the seal mark located on the lid side, so that a seal can be passed perpendicularly down the lid and the upper edge of the load carrier. Four. Five

In an especially advantageous embodiment, the seal mark is arranged in a staggered manner inwardly with respect to the side wall and / or the upper edge of the side wall and / or the cover. Such a cavity not only serves to increase the recognition of the seal mark, but also for the easier application of a hole in the seal mark. The tip of the drill bit of the drill can be placed in the cavity for example in the wall piece, the cavity defining a guide line for the drilling direction. In this way, the drill is guided in a suitable direction, namely the direction towards the separate chamber, to achieve a clean seal passage hole. In this way, the delimitation or junction nerves are safely prevented from being drilled. The stepped inward cavity is made especially circularly, but it can also be made rectangular or narrowed. 55

In another embodiment of the invention, the seal mark is marked in color, by means of a print or by another graphic symbol, so that the seal mark can be seen well from the outside. The seal of the large load carrier is facilitated because the point for drilling can be identified immediately and can be drilled directly on the mark in the direction of the separate chamber. Advantageously, the mark can be clearly distinguished from both the side wall and the outer side of the cover preferably made with a single wall.

Next, a preferable embodiment of the invention is described with the help of the drawings. They show:

In figure 1 two of the four double-walled side walls 3, 4 of a support of large loads 1 not fully represented in this representation are shown, with a front outer wall 4 and an outer wall being represented in partial view 3 longitudinally as well as a cover 5. In the embodiment shown, a flange 17 protrudes from the outer edge of the cover 5 perpendicularly downwards. The double-walled side walls 3, 4 of the large load carrier 1 are arranged in a peripheral edge of the bottom 2. The double-walled side wall 3, arranged on the longitudinal side, has a seal 6 on the outer side arranged in the upper area of the side wall 3 located on the longitudinal side. In this support of 20 large loads 1, the seal mark 6 is arranged at the end of the double-walled side wall 3, located on the side of the corner. The cover 5 is represented in a closed state with respect to the side walls 3, 4. In this first embodiment, a connecting element 18 is also shown that joins the cover 5 to the side wall 4. The seal mark 6 provided in at least one of the double-walled side walls 3, 4 is made in figure 1 as a circular mark. In this representation another mark of 25 seal 16 is also shown, which is useful, for example, in the case of the subsequent application of a seal wire. The seal marks 16 of this type, located on the side of the cover, can be arranged individually or multiplely, preferably corresponding to the mark 16 on the outer wall in the cover. In this representation, the mark 16 located on the side of the lid is oriented slightly offset with respect to the seal mark 6 located on the side of the container. 30

In Fig. 2 a partial section of the large load carrier 1 is also shown, a section being made in the front side wall 4, in the longitudinal side wall 3 and in the cover 5. The seal mark 6 is also represented in section cross. The connecting ribs 9 that bridge the hollow space and that connect the outer side wall piece 13 with the inner side wall piece 15 are arranged at homogeneous distances 35 between them. However, the distance of the different junction ribs 9 joined together by welding can also vary (not shown here). Individual hollow spaces 7 that are formed between the connecting ribs 9 are also shown. A hole is also shown which in this embodiment leads to the separate chamber 8 '. The chamber 8 'extends longitudinally from the inner side of the outer wall piece 13 to the outer side of the inner wall piece 15. Therefore, the chamber 8' ends on the outer side 40 of the inner wall piece 15 and not through it. The seal mark 16 located on the side of the cover for the passage passage of seal 19 located on the side of the cover is arranged in alignment and near the mark 16 and slightly offset inwards with respect to the outer edge of the cover 5. In addition, it is aligned with the upper front edge of the side wall 3. Another hole 21 is located on this front edge or on the upper edge of the double wall side wall 3 of the large load bearing 1, said seal passage hole 21 also being marked with a seal mark 22. The seal passage hole 20 is also represented which after drilling the outer wall piece 13. Through holes 19, 20 and 21 it can be made the cover 5 and the body of the support of large loads 1 are secured through the sealing wire.

In Fig. 3 a second embodiment of a chamber 8 according to the invention of the support 50 of large loads 1 is shown in which the chamber 8 is made rectangular or square between the outer wall piece 13 and the wall piece interior 15. The chamber may also have a circular or diamond-shaped plant or any other suitable shape. A horizontal cross-section of said double-walled side wall 3 and of the chamber 8 especially shows the separation of the connecting ribs 9 with respect to the vertical delimitation ribs 11 of the chamber 8. The ribs are arranged at homogeneous and parallel distances between 55 yes. However, a homogeneous separation is not essential. The horizontal delimitation rib 12 of the chamber 8 is connected to the vertical delimitation ribs 11 and forms the small volume chamber 8, separated from the hollow space 7. The bore extends through the inner wall and outer wall pieces, being corresponding seal marks provided both inside and outside. The seal mark located on the side of the lid is aligned with the interior space of the container, but near a side wall. 60

Figure 4 shows a partial view of a double wall side wall 3 with a separate 8 "chamber that with

a partial section of the connecting ribs 9 and the horizontal delimitation ribs 12 is separated from the hollow space 7. As in the embodiment of the chamber 8, shown in Figure 3, also here the circular seal mark 6 of chamber 8 "is preferably arranged centrally in chamber 8".

A perpendicular cross-section of one of the double-walled side walls 3, 4 of 5 is shown in Figure 5, a cavity 14 being provided as a seal mark on the outer and inner side wall pieces 13 and 15. The chamber 8 ' It is formed by a socket 10 in the form of a hollow soul that bridges the hollow space between the side wall pieces 13 and 15 and can be connected to them by welding. The bushing can also be a component made in one piece of one of the side wall pieces. After applying the drill bit in the cavity 14, the seal passage hole can be drilled and finally a seal 10 can be passed through the outer wall piece 13 through the chamber 8 'and out of the inner wall piece 15 .
