DESCRIPTION:
BRIEF SUMMARY
The present invention relates to a transportation device for piece goods, consisting of a frame with an upper guide for at least a first rod held and guided on this guide and with further rods which likewise extend on the upper guide or on a guide parallel hereto at a distance beneath the upper guide substantially parallel to the first rod, wherein the rods carry a web material which between the rods held in the guides forms loops as receiving pockets for piece goods.
Such a device is known from the German Patent Application No. P 41 38 507.1.
To explain the terms used within the framework of the present application, it is additionaly pointed out that, in a similar manner also in the case of the above-mentioned application, the term "frame" is to be understood very broadly and includes all kinds of open and closed supports or frames, including closed boxes or cases which only consist of side walls and base and/or cover. The terms "frame" and "container" are therefore used largely synonymously in the present application. In addition, the term "web material" is also formulated very broadly and includes foils as well as fabrics, nets and individual strips, arranged parallel adjacent to each other, of foil- or fabric material or of cords. The web material is respectively suspended on two adjacent rods and hangs downwards between these two rods in the form of a loop, forming a receiving pocket. On the end face, these pockets or loops can be open or closed, e.g. they can also be closable by means of an--optionally elastic--band, so that the two opposing parts of a pocket are held together at the end faces. The web material can extend optionally only between two respectively adjacent rods, so that respectively two rods with the pocket situated therebetween are independent of the remaining pockets, preferably however the web extends over more than two rods, so that a series of cohesive loops or pockets is formed.
Such transportation devices are primarily intended for the transportation of piece goods, in particular for the transportation of respectively similar piece goods which are required as finished pieces or as components or semifinished pieces for the production and assembly of more complex objects. An example of this is body parts in the automobile indutry which, for example, are punched and formed in a body factory a distance away from the assembly factory for the cars and only then have to be transported to the assembly site. Many piece goods are sensitive to scratching, shocks or impacts, because they can hereby be either destroyed, damaged or deformed or else at least become unsightly. They are then possibly unusable for the further processing- or manufacturing process.
The concern with such piece goods is therefore that a corresponding transportation device protects the individual objects reliably from such damage.
Furthermore, in the case of piece goods which are produced for further processing or assembly, the loading- and unloading process must be simplified and accelerated as much as possible. In actual terms, as far as possible not every individual piece has to be packed in its own container with corresponding padding material and the container then also further closed, because packing into such containers and the subsequent removal is extremely time-consuming and makes the production process considerably more expensive, to which the packing material, which under certain circumstances is extremely expensive, contributes. In this respect, devices are preferred which can be reused more or less completely and unchanged.
The device known from the prior art according to P 41 38 507.1 which refers back to the applicant's legal predecessor, already satisfactorily fulfils a part of the above-mentioned requirements. In so far as details within the framework of the present application are not described precisely, in particular as regards the construction of the individual pockets and loops and also their suspension on the rods, then reference is to be made to the above-mentioned application, the features of
