Description

BACKGROUND OF THE INVENTION The present invention relates to a pallet of flammable or flammable packaged piece goods formed in the form of an upwardly open, stackable prismatic box of non-combustible material having a closed bottom and side walls extending upward from the closed bottom.

BACKGROUND OF THE INVENTION

Storage pallets for storing and transporting components and parts, which may also be referred to as support plates, serve both for storing manufactured parts, components and assemblies and secondly as transport carriers for transporting these parts from the supplier to the next processor or for final assembly of the final product. Particularly during the time logistics and program control of the production process, at least part of the warehouse content is converted to transport capacity, so that no unequivocal differentiation of storage and transport units is possible and therefore suitable transport pallets should meet the different requirements arising from storage and transport needs.

Particularly high security technology requirements are placed on storage pallets and containers for storing and transporting flammable or flammable packaging material. In order to ensure the necessary fire safety, it is essential to ensure that, for example, when a fire occurs in a warehouse containing a plurality of stacked and stacked component storage pallets, the fire cannot be extended to other containers and pallets or to the entire warehouse.

From a safety point of view, transport boxes of non-combustible material, for example of metal material, closed from all sides or at most open upwards would be optimal for this purpose. However, these cartridges are heavy in weight and the products stored and transported are difficult to load and unload due to all the closed side walls of the cartridge, so that they are not considered suitable storage units for storing components and are therefore not acceptable for transport and industry. This is particularly true for suppliers of motor vehicle parts in the automotive industry. It has hitherto been customary in the art to convey, for example, plastic bumpers for motor vehicles for final assembly on support plates which consist essentially of a rectangular base plate provided with corner columns at the corners or provided with two opposite side walls on two opposite sides only, basically a trough hull that can be placed on equally formed hulls and used to form a stack of pallets. In this component carrier, parts such as body parts, dashboards, bumpers and spoilers of plastic and the like are stacked side by side and between upwardly extending side walls. In addition, it is also customary for elongate parts having a greater length than the component carrier to protrude from its open sides.

While the parts and components that are open to the sides can easily be loaded and unloaded, these carriers do not meet the safety requirements, in particular because they are virtually incapable of preventing the flame transfer within each stack formed from the filled stack during fire. Bottom up component carriers. This also applies if the parts and components themselves are not flammable or difficult to flammable, but are individually packaged, for example, in paper packages or paper boxes to prevent scratches or other damage to the surfaces of parts by hitting adjacent parts or shipping carrier or damage to protruding parts of the parts. Again, this is particularly true for both painted and unpainted bumpers, spoilers and similar parts of motor vehicles.

DE 27 30 445 C2 discloses a stackable loading plate with removable side walls. With this known loading plate, the side plates must first be lifted upwards and then folded inwards in order to eventually slide upwards. This operation is difficult and even impossible to load when the pallet is loaded, so often these sidewalls are not able to be removed to save transport space and reduce the weight of the loading plates. In addition, the need to separate the individual items with a delicate surface area one by one on this loading plate can be avoided, since loose objects could slide together and scratch each other. Therefore, for cost reasons, the articles are usually packed in paper boxes or paper packages, which results in an increased fire risk and inevitably results in a quantity of unusable waste material.

Accordingly, it is an object of the present invention to provide a component carrier of this kind to provide fire protection for stored articles, to allow for quick and easy loading and unloading, and to save only once-used packaging materials without exposing delicate items to transport.

The essence of the invention

This object is achieved by a storage pallet for accommodating the components according to the invention, characterized in that two mutually opposed side walls are rigidly and permanently connected to the closed bottom and the two other side walls are formed in the form of removable fire walls which connect tightly and without gaps to the closed bottom and to the fixed side walls, and can be mounted from above into the dismountable fasteners, wherein in the floor surface of the closed bottom there are formed overlaps which are accessible from above, to which is a transportable securing device.

In the solution according to the invention, component carriers in the form of pallets provided with removable side walls, in the form of walls providing fire protection, are used for storing the components in the warehouse, so that a box container is sealed against fire and only open upwards. This creates a closed fire protection tray, so that the air circulation in the inner space of these pallets is significantly reduced in the case of individual stacked component carriers, and no flame jumps can occur even if a fire occurs in one of the lower component carriers. A particular advantage of the solution according to the invention is that the component carriers are practically equivalent to closed containers in terms of fire safety, which results in reduced fire protection costs and also in lower insurance premiums.

As a rule, both the carrier base body for storing and transporting the components and the removably fire-resistant carrier walls are made of metal profile bars and sheets. This basic design can be further improved from the standpoint of fire safety by having fire walls made of heat-dissipating materials or provided with cooling fins or other similar design features.

IN;

Removably the fire walls are removed from the component carrier for the transport of parts and components, for example by trucks. This operation can be carried out easily and quickly in the device according to the invention, since it is sufficient to lift these fire walls only to release the interlocking interlocking means without interlocking the walls as in the known solutions or to disassemble the connecting means. After removal of the fire side walls, the component carrier is transformed into an open conveying state in which it preferably has a particularly low net weight. In addition, the objects to be conveyed can be easily loaded and unloaded by the open sides.

A further advantage of the component carrier according to the invention is that the individual mounted components can be fastened very simply and securely to the component carrier ¹ and also secured to each other by a locking device which can be fixed to the transport fasteners formed in the floor surface of the closed bottom. The locking device may be formed, for example, by rubber fastening strips or similar fastening elements which are provided at their ends with hooks adapted to engage behind the transport fasteners. Because the components do not touch each other and do not touch the side walls of the storage pallet, the surfaces of the components cannot be scratched, impacted or otherwise damaged. Therefore, it is not necessary to provide the stored and transported components with separate disposable containers, for example in the form of plastic sheets, paper sheets or boxes. In addition to the environmental conservation achieved by not using packaging materials that otherwise represent a significant amount of waste material, the fire protection of stored articles will also increase, which is also associated with the elimination of the use of generally readily flammable material for packaging individual components. A further advantageous consequence of the design of the storage pallet for accommodating the components according to the invention is that by providing the pallet with removable fire walls and providing transport fasteners in the uninterrupted floor area of the closed bottom of the storage pallet, a particularly high fire resistance is achieved.

In a preferred embodiment of the invention, the detachable fire wall joints are joints consisting of retaining pins and bearing housings. In this embodiment, the hinge or retaining bolts are either fixed vertically on the fire walls and the housing housings are fastened to the base body or the arrangement of the coupling parts may be just the opposite. These joints are very easy to make and their practical design is cost-effective and allows particularly quick and easy removal of the fire walls.

In a preferred particular embodiment of the pallet according to the invention, the transport brackets are embedded in the floor surface of the closed bottom. This can be achieved, for example, by providing trough or groove recesses in the floor surface of the bottom in which the gripping bars, lifting eyes or hooks and the like gripping elements are fastened to the hook of the lifting device. The floor surface of the closed bottom of the pallet in this solution has no upwardly protruding parts, so loading and unloading of the piece goods is very easy, since the parts stored or removed by sliding on the floor surface cannot get caught in any way.

In yet another preferred embodiment of the invention, the transport fasteners are in the form of grooves in the floor surface of the closed bottom, in whose cross section the holding profile is arranged. Hooks attached to the ends of the elastic straps or belts can easily engage from behind the retaining profiles. In this particular preferred embodiment, the individual mounted components can be mounted longitudinally along the recesses at any point so that groups of different components can be stacked close together on the receiving pallet in such an arrangement that the components side by side and the component are as close as possible. they did not touch each other directly.

Another advantageous embodiment of the invention proposes that the closed bottom and the fixed side walls be connected to a profile frame comprising vertical columns, provided with a plug-in pin at one end and a receiving opening at the other end, so that the pallets can be stacked on top of each other. a plurality of multi-storey assemblies, wherein the insert pins are adapted to be inserted into the receiving opening of the lower receiving pallet. This profile space frame can be formed by welding from U-shaped, T-shaped, double-T-shaped or annular profiles or a polygonal, especially rectangular, profile. In the spatial frame made of profile rods, steel plates are stored and fixed by welding. In this preferred embodiment of the pallet according to the invention, vertically extending columns, which are generally located at the corners of the pallet base surface when stacking a plurality of pallets apart, carry particularly good loads from the upper pallets, the stability of the pallet stack being perfectly ensured by pivot joints spatial frames of pallets.

and

In accordance with another preferred embodiment of the invention, the pallets are provided on their undersides with side pockets. These pockets serve for easy handling of the pallet pallets, as the forks of the forklift or stacker or other handling equipment can be inserted into the pockets.

In yet another preferred embodiment of the holding pallet according to the invention, the pallet for holding and transporting the components has the shape of a low flat prism. In this preferred embodiment, the pallet has a relatively large footprint compared to its height, so that stored and transported parts and components can be deposited in a single layer on the floor surface of the closed pallet bottom, which makes automated or manual picking considerably easier a space that is available to fill with components.

BRIEF DESCRIPTION OF THE DRAWINGS

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 shows an axonometric view of two superposed component carriers in the form of pallets for transporting piece goods and components; and FIG. 2 is a cross-sectional view of a pallet according to the invention.

DETAILED DESCRIPTION OF THE INVENTION

FIG. 1 shows two stacking pallets 1 for stacking goods and components. Their base body is formed in the form of a flat prism, the edges of which are formed by a frame 2 composed of profile bars with a rectangular cross-section.

For example, the frame 2 is welded from steel profile bars and is provided with a closed bottom 3 on its underside and two side walls 4 which can be formed, for example, of steel sheet, which is attached to the frame 2, are fixedly mounted on two opposite sides. welded.

The two other side walls are in the form of removable fire walls 5, which can also be made of sheet steel. The fire walls 5 are provided at their upper corners with downwardly directed retaining pins 6, which can be inserted from above into the sleeves 7, welded on the frame 2. In FIG. 1, the upper fire wall 5 is shown in the raised position. the lower wall pallet 1 is shown in the mounted position, the retaining pins 6 are hinged in the bushes 7 on the frame 2. As can be seen in this example In the installed state, the fire wall 5 connects tightly and without any gaps to the fixed side walls 4 and also to the closed bottom 2 ·

Further provided on the closed bottom 2 are transport clips 8 which are recessed in a horizontal position inside the trough 9 and which are formed by gripping rods fixed at their ends to the closed bottom 2. In the illustrated embodiment, the trough 9 runs along the fixed side walls 4. ·

Attached to the underside of the pallet 1 are side pockets 10, open to the side, which can for example reach the forks of a forklift (not shown) or a stacker.

The vertical posts of the frame 2, which is a spatial frame, are provided at their lower end with sliding pins 11 which, when stacking a plurality of receiving pallets 1, slide into the receiving openings 12 formed at the upper end of each vertical post. frame 2 lower storage pallets 1.

Giant. 2 is a cross-sectional view of an exemplary embodiment of the storage pallet 1 of FIG. 1, wherein like parts are designated with like reference numerals.

In this exemplary embodiment, a stored and transported component 13, inserted into a storage pallet 1 and fixed for transport, is additionally shown. The component 13 may be, for example, a plastic bumper for motor vehicles, a spoiler or a dashboard, its position during transport being secured by tensioning belts 14 which are gripped by the bar transport brackets 8. In the basic arrangement the tensioning belts 14 are always wrapped once around the component 13 and the hooks 15 at their ends are engaged by the transport fasteners 8.

The storage pallet 1 according to the invention is handled as follows: When loading the storage pallet 1 with piece goods or components 13, the fire walls 5 are removed, so that the components 13 can easily be inserted by two opposite open sides into the interior space of the storage pallet 1 and the closed bottom 3 wherein the transport lugs 8 are fully embedded in the closed bottom 3 so that they do not obstruct this insertion in any way. Once the maximum possible density of the stored objects is reached, the components 13 are secured with the tensioning belts 14 by wrapping them around the stored components 13 and then hooked by their hooks 15 by the transport fasteners 8. The components 13 are firmly secured in their storage positions and are very effectively protected against damage caused by impact or scratches. As a result of this safe storage and securing, it is no longer necessary to use other packaging materials, generally harmful to the environment or flammable, to protect the components 13 against damage.

If the storage pallets 1 filled with the components 13 are to be put in place in the warehouse, their two open sides are closed by fire-resistant fire-resistant walls 5. This operation is particularly easy to accomplish in that the fire wall 5 simply hangs by means of its retaining pins 6 into the sleeves 7 welded to the frame 2. This step creates a box closed from all sides, which is only opened upwards and which can be when using the plug pins 11 and the receiving holes 12, stack in any number on top of each other. It is advantageous here that the tightly mounted fire walls 5 are such that the circulation of air between adjacent and / or stacked stacking pallets 1 is such that, in the event of a fire, the flames cannot jump from one stacking pallet 1 to the upper or adjacent stacking pallet 1. 1 are particularly resistant to fire, in particular because both their base body and the fire walls 5 are made of a metal which dissipates heat very well during a fire.

For the transport of the filled pallets 1, the fire walls 5 are again very simply removed by sliding them up and down, which is very time-consuming and labor-intensive and at the same time reduces the transport weight of the pallet 1.

At the assembly site, the components 13 can again be easily removed after unfastening the tensioning belts 14 with the upper open side, whereby the components 13 cannot be damaged as a result of sinking the transport fasteners 8 to engage the retaining straps 14 in the closed bottom 3.
