Description

The The invention relates to a large cargo carrier according to the preamble of Claim 1.

Charge carriers that according to Euro standard a base area from 1,200 × 800 mm, or according to ISO standard a base area from 1,200 × 1,000 mm, or each division thereof, are in large numbers standardized and therefore reasonably priced. If charge carriers this Exceed dimensions, they are referred to as large cargo carriers in the context of the present proposal.

in the As opposed to simple pallets, they are covered by the present Proposal as a charge carrier or large cargo carriers objects not only a more or less flat bottom plate, but they extend from this bottom plate upwards for optimum product protection to enable.

such Become cargo big carrier then necessary if the load exceeds the aforementioned standard dimensions. In the field of automobile production, this occurs, for example, if from the supplier to the car manufacturer bumpers or Front or rear aprons for the Body of an automobile to be delivered.

Out In practice, it is known, large cargo carriers for each job individually to make and, for example, to create metal, for example in the form of closed boxes, which are made of corresponding metal sheets, or in Form of so-called grid boxes, which have a frame and Wall elements consisting of a wire mesh.

Around it is still out to avoid the disadvantages of large metallic cargo carriers known in practice, large cargo carrier made of plastic to accomplish. These protect the goods transported in them due to The plastic-typical resilient surface, moreover, they are comparatively lighter and in particular corrosion resistant. The disadvantage of such Made of plastic existing large cargo carrier is in their high Production costs, since the individual elements, ie floor and wall elements and a possibly provided lid, in specially manufactured injection molds be created at a substantial cost Need to become. moreover requires the production of injection molds a considerable time Advance until the first such large cargo carriers can be produced.

Of the Invention is based on the object, a generic large cargo carrier to the effect to improve that he also in smaller numbers as well as in almost any Dimensions within the shortest possible time Time and with as possible low cost can be produced.

These The object is achieved by a large cargo carrier with the features of the claim 1 solved.

The Invention proposes in other words, the manufacture of the cargo bulk carrier with standardized Semi-finished products, namely under Use of plastic profile elements that are interconnected to form a framework. Here are lower profile elements ring-shaped, for example in the form of a rectangular ring, while others Profile elements one in contrast form upper ring. Support, also made of profile elements, connect these two rings together and thus create a solid bond of the total created Frame, and on the other hand hold the two rings one above the other at a distance, so that in this way a framework is created, which within the protects the frame arranged charge.

There designed the profile elements, for example, as extruded profiles can be can they are cut to almost any length be so highest individual dimensions of the large cargo carriers are made possible the optimal adaptation to the respective load or an optimal Allow room usage.

Farther can individually dimensioned Cargo big carrier inside short Time to be made, since not only special molds made Need to become, to manufacture the cargo bulk carrier to be able to. Rather need only the standard provided Profile elements can be cut to the desired dimensions to to form the corresponding frame, so that then the large cargo carrier with the wished Dimensions present. Even if for the vertical supports others Profile cross sections should be used as for the circumferential rings, result very few different components making up the proposed large cargo carrier, so that a highest economical production also very different sized cargo bulk carrier is made possible.

Advantageously, the large cargo carrier can make it unnecessary to provide a separate pallet, so that a particularly simple handling of this large cargo carrier is made possible by virtually equipping it with its own pallet. For this purpose, it can be provided that a total of three rings are provided, of which the mitt Lere is provided at the height of the floor, which has the large cargo carrier. The two lower rings, so the middle and a third, even deeper arranged ring, have a small distance from each other, which should only serve to form the entry pockets for lifting tools, ie to provide a retractable space in which the tines z. B. a forklift or a lift truck can be inserted. The distance between the very low central ring and the upper ring then defines the receiving volume which the large cargo carrier provides for receiving the cargo.

Advantageous can the profile elements have hollow profiles. That way, one becomes lightweight and rigid construction of the frame allows.

Advantageous can in such a hollow profile another, namely arranged an inner reinforcing profile be. In this way, the bending stiffness of the profile element considerably improved, with only a little larger material costs.

Advantageous can both the hollow profile and the mentioned reinforcing profile are made of plastic, in particular from the same plastic. This way, later becomes one particularly problem-free, unmixed disposal of the large cargo carrier allows. In addition, for the welding of several Profile elements in that as possible the same material is used, which improves welding quality and one possible high strength of the frame achieved.

The reinforcement profile can be used in particular at particularly stressed points to reinforce the hollow profile be provided. Advantageously, however, the reinforcing profile almost over the entire length of the hollow profile extend. This way becomes a special one simple, joint handling of the hollow sections and the reinforcement profiles allows the one possible facilitated largely automated production of large cargo carrier and Avoiding the handling of smaller, separate components as far as possible.

Advantageous can mutually facing grooves provided in two adjacent columns be, so that, for example, labels od. Like. in these opposite ones Slots can be inserted.

To an optimal To enable product protection is provided, this access opening by means of a movable cover such as a lid or a Optionally close the flap or open to be able to.

An optimal transport safety for the products can be created by the fact that the soil is adapted by means of a special profiling to the geometry of the individual parts to be transported within the large cargo carrier, so that the soil forms a so-called workpiece carrier. A workpiece having a recess, for example, can be transported in a particularly secure position when the floor forms a correspondingly adapted projection, on which the workpiece can be placed with its recess. Conversely, the bottom can have recesses into which projections of the respective workpiece to be transported can protrude. In any case, a positive connection between the bottom and the workpiece is achieved, so that on the one hand, the contact of two adjacent Workpieces and mutual damage is excluded and on the other hand reliably held in place when driving over bumps each workpiece in its place.

The wall surfaces of the cargo carrier can one Have profiling. For example, the wall surfaces can be vertical Ridges or grooves are provided to be set flat elements, set from the top into the cargo bulk carrier be sure to guide. Alternatively you can the wall surfaces have horizontal ribs or grooves to either way in this way large workpieces or in turn, take more re workpiece carrier, the similar like different shelves arranged in a shelf.

Advantageous can the profiled floor or wall elements as each deep-drawn Be configured plastic element. That way you can one the workpieces optimally gentle surface geometry of the floor or wall element achieve a perfect fit, optimal to the workpiece geometry adapted shape.

alternative or in addition to the opening mentioned above, which may be provided in a wall element may be advantageous be provided that the entire wall element is movable, so for example Removable or hinged to the cargo bulk carrier is attached. To this Way, a very large opening of the Cargo bulk carrier released which allows unhindered access to the cargo. Especially if - like previously described - several Workpiece carriers shelf-like one above the other are arranged, can easily such a workpiece carrier pulled out the cargo bulk carrier be, for example, if all the workpieces thereon before have been taken. This allows a very high packing density the individual workpiece carrier one above the other achieve, as the access to a respectively lower workpiece carrier easily allows is done by the above located workpiece carrier easily removed from the cargo bulk carrier can be.

Advantageous can the frame forming profile elements mitred to each other connect and welded together be. To achieve as much as possible high strength of the welded joint is the welding over one as possible size area advantageous. The contact of two adjoining profile elements mitred a maximum contact area or Welding surface.

anyway can be provided particularly advantageous, the individual profile elements, that form the frame of the cargo carrier, to weld together. In this way, an automated production is easily possible.

Also the pillars, who connect to a ring, can Accordingly advantageously be welded to the ring.

In in a known manner the welds here designed as so-called mirror welds be. Such mirror welding is done by contact of the two to be welded Elements with a flat, hot Welding tool, which is pulled away when the two welding partners are sufficiently heated. These are pressed against each other, so that then the connection between the two welding partners he follows.

alternative can be provided that the supports are sleeve welded to the ring. In this way, a particularly large contact area or Welding surface, so that a particularly stable frame construction is made possible. At the socket welding a pin-like connecting part is provided, which on the one hand extends into the ring and on the other hand into the support, so that the welding not just along the contact surface between prop and ring can be done, but also significantly larger area along the surface the peg-like connection part.

Around preferably just a big one To be able to produce a variety of different frame dimensions, are the profile elements advantageously designed as a straight profile bars. Accordingly, results in the production of a ring of the frame always a polygonal configuration of such a ring.

The Support are advantageous there welded to the ring where a seam between provided two adjacent profile elements of the ring is, for example, at the corners of a polygonal ring. there extends the contact surface the prop with the ring on both sides the seam line, so that not only weld the support to the ring the fundamental Connection between support and ring causes, but also an additional connection of the two causes adjacent profile elements of the ring.

by virtue of the advantageous automation in the production of the frame for the Cargo bulk carrier is in principle a welded joint the individual profile elements both within a ring and in the connection of support and ring provided.

To a particularly high load capacity of Ensure frame, a screw connection between support and ring may be provided, this screw can be advantageously provided in addition to the principle provided welding.
