Definitions

  • the invention relates to a method for packaging metal coils with the method steps listed in the preamble of claim 1.
  • the method known from practice, the method steps of which have been explained in the preamble of claim 1, is a method for packaging aluminum coils. For a variety of reasons, these are transported in such a way that the coil eye is closed; accordingly, the coil is wrapped over the entire surface with stretch film in all process stages.
  • the expedient of this known method is that by using the lamella packaging in a very simple manner, edge protection of the outer edges of the end faces of the coil is realized by itself.
  • a lamellar packaging is a packaging material that is easily foldable in one direction and stiffened in the transverse direction by rigid lamellae, usually made of wood, pressed wood or plastic in connection with paper, plastic-coated paper or plastic films. This has also been known in practice for a long time (see for example also DE-GM 90 04 345).
  • the invention has for its object the known method for packaging metal coils with the method steps of the preamble of To design and further develop claim 1 so that it can be used for coils, in particular steel coils, with a coil eye open in the middle.
  • the further essential step in the method according to the invention lies in the inner disk made of plastic used at each end of the coil eye after being wrapped twice with stretch film in the manner known per se, but with the coil eye remaining open according to the invention.
  • the plastic inner blank With this inner blank, the protruding material of the stretch film is pressed to the side and fixed, the plastic inner blank has a sufficiently high inherent elasticity and, in conjunction with the adhesive effect of the stretch film, an excellent sealing effect. This is particularly true when the plastic inner disc, as is known per se, has an inner angle of somewhat less than 90 ° in order to produce a corresponding prestressing effect (DE-GM 90 04 345).
  • This process is advantageously carried out by working with different stretch film rolls for process steps b) and d).
  • a full-surface protection of the end face of a coil with a full-surface blank is known per se from the prior art (DE-GM 90 04 345)
  • circular blank explained in claim 5 can have thicknesses between 3.0 and 5.0 mm, preferably between 3.2 and 4.5 mm.
  • the use of a protective sleeve in the interior of the coil eye according to claim 6 is also known per se from the prior art.
  • a corresponding overlap should be provided, with the inner discs then also being used to additionally fix the protective sleeve could serve.
  • the process according to the invention leads to an excellent process result, since it is possible to pack coils with a centrally open coil eye, in particular steel coils, in an extremely economical and therefore cost-effective manner.
  • This process can be carried out at least semi-automatically.
  • a major advantage of this process is the clever use of packaging materials that allow multiple use. When using recycling materials, extreme environmental considerations can also be taken into account. Almost all of the components used are environmentally friendly and easy to dispose of. This applies in particular to the hard fiber material of various parts, to the lamella packaging and to the plastic inner blanks.
  • FIG. 1 shows schematically on the left three coils 1, in particular steel coils, which are transported from a roll stand on a coil transport device 2 to a film stretching system 3.
  • the film stretching system 3 there are two support rollers 5 on a turntable 4, which are themselves driven again in order to be able to rotate or roll a coil 1 placed thereon about its longitudinal axis.
  • Part of the film stretching system 3 is also a stretching tower 6 and a feed device 7 for a lamella packaging 8, in the exemplary embodiment shown three lamella packaging 8 side by side and parallel to one another.
  • the film stretching system 3 is followed by a further transport path 9, to which a binding system 11, also provided with a turntable 10, is connected, which also includes a band steel binding unit 12.
  • FIG. 2 schematically shows a coil 1 which has previously been conveyed by the coil transport device 2 onto the turntable 4 of the film stretching system 3, for example by means of a crane or a lifting conveyor.
  • This coil 1 here a steel coil
  • This coil can be untreated or treated, for example galvanized, painted, oiled, etc.
  • FIG. 2 shows, schematically, the final state after implementation Process step b), in which the coil is wrapped with stretch film 14 on all sides - in multiple layers - here, however, according to feature g) in such a way that the coil eye 15 is open on both ends, but the stretch film 14 extends somewhat into the coil eye 15, here about 10 to 15 mm, exaggerated.
  • it can be normal stretch film 14, but it is particularly preferred if, as explained in claim 2, a corrosion protection film, for example a VCI-coated stretch film, is used, which at the same time protects the surface of the coil 1 against corrosion.
  • a corrosion protection film for example a VCI-coated stretch film
  • Fig. 3 now further shows the method step c), in which the coil 1 is wrapped over the entire surface of the coil jacket with the lamella packaging 8 in one layer.
  • the essential wrapping technique in which the lamellar packaging 8 protrudes somewhat on the end faces of the coil 1, here approx. 100 mm on each side.
  • the exemplary embodiment shown is additionally characterized in that full-surface blanks 16 are attached to the end faces of the coil 1, as described in claim 5.
  • Fig. 3 shows the preferred measure described in claim 4, namely that in this process step with at least two, here with three simultaneously and parallel tapered lamellar packaging 8 is worked much smaller width than the coil 1 and the total width of the individual lamellar packaging 8 the width of the coil 1 exceeds in the intended manner.
  • three lamella packaging 8 are used in two different widths, for example a width of 600 mm and a width of 400 mm, coils 1 of almost any width can be wrapped by a different combination of these two lamella packaging widths.
  • the protective sleeve explained in claim 6, which is intended to protect the coil eye 15 inside. It is known from the prior art and represents a type of tube which is pushed into the coil eye 15. This happens if such a protective sleeve is provided at all, particularly expediently after the second stretch film 17 has also been applied.
  • the protective sleeve is used in particular when the coil 1 is to be transported by sea, in order to avoid splashing water and / or condensation water from the inside to get here to Coil 1.
  • Fig. 5 shows a further, very essential process step of the method according to the invention, namely the process step according to feature h), in which a plastic inner disc 18 is inserted into the coil eye 15 on both end faces, which covers the end face laterally over a certain width in a flange-like manner.
  • a plastic inner disc 18 is inserted into the coil eye 15 on both end faces, which covers the end face laterally over a certain width in a flange-like manner.
  • the plastic inner disc 18 is of particular importance for the illustrated embodiment of the method according to the invention because, in conjunction with the stretch film 17 and possibly 14 and the self-adhesive force of such a stretch film, it contributes to a very excellent sealing against moisture ingress at the coil eye 15.
  • Fig. 6 then finally shows the final process step according to i), whereby it can be seen that the band steel tensioning straps 19 provided here are guided through the coil eye 15, so that the inner blanks 18 are fixed at the same time, even pressed flat with the build-up of pretension , so that there is an extremely good seal to the stretch films 17, 14 out.
  • the method according to the invention is of particular importance insofar as it permits the use of semi-automatic or even fully automatic machines which can also be integrated in packaging lines.
  • An example of a film stretching system 3 with a turntable 4 and, preferably driven support rollers 5, is finally shown schematically in FIG. 7.
  • the direction of rotation of the coil 1 is determined by the Arrow indicated.
  • On the right below the turntable 4 one can see the lamellar packaging 8, which is available as folded goods in two different widths.
  • the feed device 7 is formed by deflection and transport rollers and guide elements arranged on the side of the turntable 4, all of which is indicated schematically.
  • a switching device is also indicated on the turntable 4.
  • the film stretching system 3 shown can have several, in particular three, start and target positions which are approached with the rotary plate 4 can. As previously explained, two brackets for stretch films and two pre-stretch rollers are recommended. Two separate stretch controls and setting options for normal and increased stretch tension are also advantageous. Different winding speeds should be able to be set as well as the possibility of driving the film stretching system 3 automatically or manually. An automatic control for the lifting slide is recommended for receiving the coil 1 from the coil transport device 2. With a creep speed, the support rollers 5 can be driven so slowly that the blank 16 can be mounted on both ends of the coil 1.
