DESCRIPTION OF THE FIGURES

[0066] Identical elements are given identical reference numbers in the figures.

[0067] The transport systems 1, 1, 1 in FIGS. 1 to 4 are all based in each case on a 40-foot ISO shipping container 2, as is shown partially transparent in FIGS. 1 to 3.

[0068] The container 2 has in each case a transport platform in the form of the floor 3 of the container 2, four side walls 4, 5, 6, 7 and a roof 8. A door 37, which closes a loading opening 9, is provided in one of the long walls 4. In addition, the front wall 5 is designed in the form of a double-leaf door, as is usual for shipping containers. An unloading opening 10, through which sections 11 of the wire can be taken out of the container 2, is additionally provided in the front wall 5. It is understood that the unloading opening 10 can be closed with the aid of a cover plate, in order to completely protect the inside of the container 2 from environmental conditions during transport.

[0069] In the embodiment represented, the container is additionally received on a rolling adapter, with the result that the container can be transported and set down with pinpoint accuracy with the aid of a heavy goods vehicle 12 equipped for it, as shown by way of example in FIG. 3. Such a rolling adapter has the same receiving hook 13 as well as rollers (not represented in the figures), as are known from roller containers.

[0070] In addition to the container 2, the transport system 1, 1, 1 in each case comprises devices inside the container 2. The basis for the transport or the delivery of a wire 18 is in each case the receptacle 14 or 14 for the coiled wire 18. The variants of FIGS. 1 and 2 differ in the design of the receptacle 14, 14 for the coiled wire.

[0071] In the case of the transport system 1 from FIG. 1 the receptacle 14 is a reel 15 for loading a so-called loose coil. i.e. a coiled wire which was coiled without a core. The reel 15 is a constituent of the receptacle 14 and is typically not changed even when wire material is added again. The receptacle 14 moreover comprises a tilt device 16, which makes it possible to adjust the reel 15 both in terms of height and in terms of the alignment of its axis of rotation 17. The height of the reel 15 is matched to the height of the intake for the wire 18 into the further devices of the transport system 1. To load the loose coil onto the reel 15, its axis of rotation 17 can be tilted such that the axis of rotation 17 is aligned substantially horizontally (not shown in the figures), with the result that it is easy for a user to hang the loose coil on the reel. The reel is then tilted such that its axis of rotation 17 is substantially vertical (as shown in FIGS. 1 and 4).

[0072] The receptacle 14 for the coiled wire of the variant from FIG. 2 has a two-part receptacle mounting 27 for a drum 19 with the wire 18 coiled thereon. In the variant with such a drum 19, almost any desired wire lengths can be provided to the customer with the aid of the transport system 1. The length of the wire is ultimately limited only by the volume of the drum 19.

[0073] The variants of the transport system 1, 1 shown are in each case a transport system for a wire made of a stainless steel which was produced by cold-forming. The long wire lengths on the drum 19 are produced by welding several wires at their end faces. The material properties of the work-hardened wires in the vicinity of the welded joint are, however, negatively altered by the welding. These must therefore be cut out of the wire 18 before the wire sections are ejected for the customer, and represent scrap which is to be recycled.

[0074] In the two variants of FIGS. 1 and 2 the wire 18 is inserted into a driving tool 20 as the drive within the meaning of the present disclosure. In particular in the case of the long wire lengths, as provided on the drum 19 of FIG. 2, one end of the wire 18 is already inserted into the driving tool 20 when the transport system 1, 1 is delivered to the customer. The finishing of the wire sections 11 can begin immediately. In the variant shown, the driving tool 20 is a roller driving tool with two rollers 21, 22, which are motor-driven and are in frictional engagement with the wire 18, with the result that during operation the wire 18 experiences a propulsion towards the unloading opening 10.

[0075] A straightening device in the form of a straightening set 23, 24 with a plurality of profile rollers is provided behind the driving tool 20 in the feed direction. The straightening set has two sets 23, 24 of rollers, wherein the axes of rotation of the rollers of the first set 23 are perpendicular to the axes of rotation of the rollers of the second set 24. The straightening device 24 serves to provide the wire 18, which has been given a curvature of its surfaces by the coiling, with the necessary straightness.

[0076] A cutting device in the form of a parting-off head 25, which rotates around the wire 18 in a motor-driven manner and severs it, is provided behind the straightening device 23, 24 in the conveying direction. After the parting-off with the aid of the cutting device 25, the wire section 11 can be taken from the transport system 1, 1 in the desired straightness and length.

[0077] FIG. 4 shows a further variant of the devices inside the container 2, wherein the container 2 is not represented in FIG. 4 for the sake of simplicity. Like the variant from FIG. 1, the transport system from FIG. 4 again also has a receptacle for a coiled wire in the form of a loose coil. In addition to the driving tool 20, the straightening set 23, 24 and the parting-off device 25, the variant of the devices of the transport system 1 from FIG. 4 has a bending device 26, which bends the individual wire sections after being parted off with the aid of the cutting device 25 such that the wire sections can then be immediately processed further, i.e. for example installed in industrial machines.

[0078] With reference to the variant of the transport system 1 from FIG. 2, the operation of the transport system 1 will now be briefly outlined. In the manufacture by the wire manufacturer, the container 2 is loaded with a wire 18 coiled onto the drum 19. The closed container 2 is then transported to the customer purchasing the wire 18. For the transport, the heavy goods vehicle 12 from FIG. 3 can be used, but the container 2 can also be loaded onto the railway or a ship. At the customer's manufacturing location, which can be a workshop or also a construction site, the container 2 is set down and the final delivery steps can begin immediately. The driving tool 21 draws as much wire 18 off the drum 19 as is required for the wire section 11 to be taken in each case. The customer receives a wire section 11 with a length and quality according to their specification.

[0079] FIG. 5 shows, in a schematic diagram, how the transport system 1 bridges the manufacture by the wire manufacturer and the further processing by the customer. For this, the transport system 1 has a controller 34 with a computer 28. This computer 28 (not shown in FIGS. 1 to 3) is connected to the individual devices of the container 2, namely the receptacle 14, the driving tool 21, and the parting-off head 25, via corresponding data lines 29. The computer 28 now assumes the control of all further delivery steps, until the wire section 11 can be taken out of the container 2 through the unloading opening 10 after the parting-off.

[0080] However, the computer 28 additionally also receives information about the operational state of the individual devices 21, 24, 25 via the data lines 29. From this information on the operational state, the computer 28 can deduce how many metres of the wire 18 have already been drawn off the drum 19 and taken from the container 2 in cut form. As the controller, in addition to the computer 28, also has a mobile radio interface 30 connected to the computer 28, the computer 28 is capable of communicating with a server 32 of the wire manufacturer over the Internet 31. The server 32 in turn is connected to a computer 33 of the customer over the internee. In this way, the wire manufacturer's server 32 can generate invoices for the lengths of the wire 18 taken from the container 2 in an automated manner. In addition, certificates for the individual wire sections 11 can be transmitted to the customer in an automated manner. If the computer 28 establishes that the entire length of the wire 18 received on the drum 19 will be drawn off within a particular time, the computer 28 triggers a repeat order for a wire 18 of the same type via the communications interface 30, the Internet 31 and the wire manufacturer's server 32. This is then delivered to the customer in a new container 2 in time. The delivering HGV 12 can then replace the empty container with the full container at the customer's location.

[0081] Furthermore, the computer 28 of the controller 34 is connected to an electronic reading device in the form of a contactless RFID reader 35. The RFID reader 35 serves to read RFID tags 36 which are arranged on the drum 19. In this way, the transport system 1 can detect, in an automated manner, the type of wire 18 which is provided on the drum 19. The corresponding information is stored in the RFID tag 36.
