Description

Bulk containers

The invention relates to a stackable large-capacity carrier for storage or for one-way and Mehrwegtrans¬ port of packaged goods of all kinds, in particular of larger, light to medium heavy parts and Baugrup¬ pen.

Load carriers are used as transport and storage containers, especially where tools or components have to be transported or stored in the course of a manufacturing process.

Closed boxes or containers made of metal, wood, corrugated cardboard or plastics are known, which are welded, glued, nailed, screwed or positively connected mitein¬ other. In this case, a sufficient load capacity and service life, as well as low handling costs for the use of the load carriers are important. In particular, the adaptation of the sizes to predetermined part geometries but also to transport means to be used, such as trucks or sea containers, play a major role.

Charge carriers made of metal are structurally heavy, susceptible to corrosion, expensive and costly in empties return transport.

Load carriers made of wood are also relatively heavy.

They are subject to substantial import restrictions due to an import risk of pests and pesticides in the export. They are expensive to handle and Risk of injury from wood splinters, nails or screws.

Wooden boxes and crates can not detect the condition of the transported parts at the recipient site without opening the containers. This is of great importance, in particular, in the case of goods in free ports, where unnecessary customs formalities can be dispensed with if there are identifiable transport damages. Timber crates and film protectors are time-consuming to assemble and hardly allow stacking of load carriers. They demand tools and skilled trainees.

Carriers made of corrugated boxes are predominantly closed containers and allow little or no insight into the interior. With comparable stack loadability, they are significantly more material-intensive and more expensive than, for example, wooden load carriers. ,

Plastic containers and plastic pallet boxes, are mostly designed for reusable transport. They are correspondingly expensive and likewise do not permit checking of the packaged goods in the packaged state.

DE 94 16 778 U1 shows a stackable transport package for household appliances, in which a plurality of rod-shaped supports can be located between a floor and a ceiling panel, which are held by tension bands. For a height adjustment, the two-part ausge¬ formed supports can be displaced against each other and locked by means of a threaded clamping sleeve. In DE 93 05 400 Ul a stacking frame is described in which a hold-down is secured by flat screws on a square U-frame.

In the load carrier disclosed in JP 2004 14 2808 AA, rolls to be transported are held between two plates by means of supports. The integrally formed ends of the supports are inserted into recesses of the plates.

The object of the invention is the development of a large-load carrier which on the one hand has a low weight but on the other hand has a high stability and stacking strength. It should be easy and inexpensive to produce. The charge carrier should be trans¬ parent executable and thereby provide sufficient insight on the packaged parts. It should be able to be manufactured in a variety of formats and heights in terms of parts and trans port space and thereby have a high pre-assembly and low transport and storage volume in the empty state. The handling effort to build up the charge carrier should be low and require no professional knowledge.

The object is achieved by the features of claim 1. Ausgestaltende features are described in the subclaims 2 to 10.

The large load carrier according to the invention consists of at least one base plate and at least one Decken¬ plate. At least three hollow profiles are fastened by means of screw connections between the base plate and the ceiling plate. The bottom plate rests on an edge formed on foot screws. The footscrews themselves are provided with a foot part and a single or multiple slotted threaded part in the axial direction. The foot screws take the hollow profiles vertically. The hollow profiles are fastened to the base plate and the ceiling plate by means of union nuts, which have a conically shaped thread. Due to the slotted threaded shank of the foot and ceiling screw in conjunction with the conically designed thread of the union nut, it is achieved that the diameter of the threaded shank can be reduced by tightening the union nut and thereby a fixing pressure with biaxial force transmission of the respective foot screw or the respective ceiling screw is exerted on the outer wall of the Hohlpro¬ file. All screw connections are made of thermoplastic material and are usually designed as injection molded parts.

A preferred embodiment is when the floorboards and / or the ceiling panels and / or the hollow profiles consist of natural fiber products, wherein the floorboards and / or the ceiling panels consist in particular of paper stock honeycomb panels and / or the hollow profiles of wound paper can exist.

The floor panels and / or the ceiling panels and / or the hollow profiles may also consist of thermoplastic Kunst¬, wherein the floor panels and / or the ceiling panels may consist of plastic hollow panels. The hollow profiles may have round or square cross sections.

If the ceiling screws are shaped at the top in such a way that they receive foot sections positively, then several large load carriers of the same design and size can be superimposed in such a way. be stacked on each other, that the load are transmitted exclusively via the tubes on the respective footprint of the underside th charge carrier. The vertical load transfer of the stacked containers on the Hohlprofi- Ie lead to very high load options, the thermoplastic feet must take over only the weight of the respective La¬ training carrier.

The large load carrier according to the invention can be wrapped by stretch film in such a way that it is secured torsionally rigid in the loaded state via diagonal tensile forces of the load carrier. The stretch film used can be equipped with VCI anticorrosion agents which diffuse to the inside of the charge carrier and protectively protect against rust on metallic surfaces within the container. The stretch film itself can also be opaque.

The construction of the large load carrier makes it possible for specific receptacles to be built inside the load carrier, which protect the goods to be transported against damage. To increase the stiffening strength of the charge carrier may have additional bracing in the cross-compound.

The invention will be explained in more detail using an exemplary embodiment. 1 shows a large load carrier

Fig. 2 Section through Fußplattenbefestigung Fig. 3 Section through Deckenplattenbefestigung Fig. 4 ceiling screw Fig. 5 union nut Fig. 6 foot screw Fig. 7 large load carrier stacked For the overseas transport of automotive parts stackable large load carriers are to be used.

In Fig. 1, a large load carrier with a bottom plate 1 and a ceiling plate 2 is shown. Between the bottom plate 1 and the ceiling plate 2 4 hollow sections 3 are fastened by means of screw. Figs. 2 and 3 show this attachment in section. FIG. 4 shows a cap screw 5 in each case, a cap nut 6 in FIG. 5, and a foot screw 4 in FIG. 6. The base plate 1 rests on an edge 7 integrally formed on the foot screw 4. The foot screws 4 themselves are provided with a foot part 8 and a thread part 9 slit longitudinally 3 times along the circumference. The foot screws 4 take the hollow sections 3 vertically. The hollow profiles 3 are fastened to the base plate 1 and the ceiling plate 2 by means of union nuts 6, which have a co-shaped thread. Due to the multiple slotted threaded shank of the foot and ceiling screw in conjunction with the conically executed thread of the union nut 6, the diameter of the threaded shank is reduced by tightening the union nut 6. As a result, a fixing pressure with biaxial force transmission is exerted on the outer wall of the hollow profiles 3 by the respective foot screw 4 and the respective cover screw 5. All screw connections are made of thermoplastic injection molding material. The slots in the threaded shanks are not shown in Figs. 4 and 6.

The floor panels 1 and the ceiling panels 2 are made of paper honeycomb panels of a thickness of 30 mm. The hollow profiles 3 are wound paperboard tubes with a wall thickness of 5 mm. If the ceiling screws 5 are shaped at the top so that they receive foot parts 8 in a form-fitting manner, then several large load carriers of the same design and size can be stacked on top of each other, as shown in FIG.

After loading, the large load carrier is very simply wrapped in an opaque stretch film in such a way that it is secured torsionally rigid via diagonal tensile forces of the charge carriers in the loaded state. The stretch film used is equipped with VCI anticorrosion agents which diffuse to the interior of the charge carrier and protectively protect against rust on metallic surfaces within the container.

In each case, 4 passenger spoilers with a weight per Spoi¬ ler of about 13.3 kg on a 2270 x 1150 x 550 mm large and about 53.2 kg heavy packaging unit housed. To accommodate the spoilers are located on the bottom plates rack made of foam, which fix the parts form-fitting. Each 4 packaging units are stacked on top of each other and five such stack after another and transported in a 20-foot container.

The advantages of the large load carrier are that it has a low weight on the one hand, but on the other hand a high stability and stacking strength. It is very simple, inexpensive and in different formats and heights parts and transport space specifically produced. It is possible a high pre-assembly. When empty, it has a low transport and storage volume. The handling effort for the construction of the charge carrier is low and requires no special Facharbeiter¬ knowledge. Reference drawing
