Definitions

  • the invention relates to a method for producing a number of wound film rolls, wherein the films are reinforced in their edge region by folding. Furthermore, the invention relates to a device for producing a number of wound film rolls.
  • plastic films In the production and winding of plastic films, it is a known solution to supply the plastic film from a film production line, for example an extruder, to a winding device in order to prepare it for further handling and in particular for transport.
  • a film production line for example an extruder
  • edges are reinforced, ie doubled or folded, a thickening in the edge region ("dog bone") arises, as already mentioned, since the film is doubled in thickness in the region of the application and builds up correspondingly strong here.
  • This also results in further processing disadvantages, such as increased outer dimensions of the wound film, which disadvantageously, for example, a larger packaging volume, blocking of the film or a high pressure on the winding tube result.
  • a second, downstream process for oscillation of the film necessary.
  • the invention is therefore an object of the invention to provide a method of the type mentioned above and a corresponding device, with which or with which it is possible to wind in a very flexible manner arbitrarily wide sections of film in a favorable manner.
  • a compact winding is to be provided directly from the film production process, which is characterized by easy adjustment both for the width of the film sections ("usefulness") and for the degree of folding of the film in the lateral edge region.
  • the process should be feasible directly from the production process of the film, ie inline, with multiple partial benefits in any setting.
  • the synchronization means are preferably formed by a pin arranged on the folding device, which engages in a recess in the oscillation drive.
  • each Umfaltelement be associated with a role over which the film to be folded is performed.
  • the axes of the rollers encloses to the direction transverse to the conveying direction preferably an angle, wherein the angle is preferably between 1 ° and 30 °.
  • the two Umfaltiata, the two rollers and the pin of the synchronization means and preferably a centering cone are preferably arranged on a common carrier plate.
  • the support plate is preferably arranged pivotable about an axis which is arranged parallel to the direction transverse to the conveying direction, wherein for an embodiment of the pivoting movement, in particular an actuator is present.
  • the present invention provides a way to "inline" a film to the desired utility width, i. H. produce several film sections ("benefits") in the desired width in one operation and to wind advantageous.
  • the proposed concept makes it possible to reinforce the edges of the film or the film areas by folding the edge inwards or outwards.
  • the folding device can oscillate back and forth transversely to the direction of production (conveying direction of the film) in order to lay the reinforced edge regions for the winding process and thus to achieve less buildup in the side region of the film roll.
  • An essential aspect of the present invention is accordingly that in the case of several "partial benefits" of the film, a synchronization takes place between knife and folding device, ie. H. These assemblies both oscillate with respect to the film or the winding devices oscillatory in the transverse direction to the conveying direction.
  • the blades of the film longitudinal section for the individual part benefits and the entire edge enhancement device (i.e., crimping devices) will move in the film transverse direction relative to that reference system.
  • Both the knife and the Umfalt Nurs, the knife and the Umfalt willen move accordingly synchronized with the winding devices.
  • a particularly simple and cost-saving solution is that the knives and the folding device are coupled by means of a driving pin or via a separate connection and thus both can be moved (moved across) with a single drive unit.
  • the gain, d. H. to easily and flexibly change the size of the folded portion of the film.
  • Each Umfalt issued can itself or all existing Umfalt prepared can be moved back and forth together to the To lay reinforced edges for the winding process.
  • a variable setting can be made.
  • the reinforced edges increase the robustness and use of the finished product. For example, the roll can fall to the floor once and still be reused.
  • the edge reinforcement further improves the mechanical properties of the film. So you may need less film than unfolded film. With conventional film, the film usually tears at the edge first. Due to the reinforcement (refolding) this is largely prevented.
  • Fig. 1 and Fig. 2 is a device for producing a number of wound film rolls to see, the film rolls are formed by each cut a film portion of defined width from a film web with a total width and wound up.
  • the device shown in the conveying direction F is preceded by a film 17 is a feeding device, not shown, for the film 17, for example, an outlet from an extruder, in which the film 17 is produced.
  • Downstream of the illustrated device is a number (not shown) winding devices for winding foil sections ("benefits"). In this case, what is preferred, also be provided that several film sections are wound on the same winding device.
  • the feeding device is just as well known as the winding devices as such, with express reference to the above-mentioned prior art.
  • FIGS. 1 and 2 Is essential to the invention rather in the FIGS. 1 and 2 illustrated arrangement. Their detailed structure goes in particular in the synopsis with the others FIGS. 3 to 6 out.
  • FIGS. 7 and 8 are finished wound film roll 1 to see.
  • This roll is a wound film section 5 which has been cut out of a wider fed film having an overall width and then wound up.
  • Fig. 8 it can be seen that the film section 5 wound up into the film roll 1 has a fold 3 in its two edge regions 2, ie a folded-over section 7 is folded over by 180 ° and applied to the remainder of the film section.
  • This refolding 3 results in a much higher mechanical stability of the edge region of the film and insensitivity of the edge region during unwinding of the roll as well as with regard to mechanical damage (if the roll falls once on the ground).
  • the supplied film is then cut into "utility", i. H. There is a cutting of the film in the conveying direction F by means of a number of knives 4, so that a plurality of extending in the conveying direction F film sections 5 arise.
  • an oscillation drive 8 is used.

  • the film section 5 is therefore first cut by means of the knife 4 and pre-oriented on the rollers 13, 14 by 90 °.
  • the folding of the film edges in the respective direction takes place, in which case by means of the Zentrierkegels 22 a second fixation takes place and a stabilization for the subsequent winding.
  • the film section 5 to be folded over in the edge region is thus preoriented by means of the rollers 13, 14 for folding (bending by about 90 °), wherein the fold-over elements 11, 12 following in the conveying direction F complete the folding (by 180 °).
  • the centering cone 22 fixes the reinforced edge and stabilizes the folded film section; Furthermore, the centering cone 22 leads the folded-over film section 5 to the winding device.
  • rollers 13 and 14 are arranged symmetrically to a center plane.
  • the rollers 13, 14 each have an axis a, which encloses a small angle ⁇ to the direction Q transverse to the conveying direction F. This one is in Fig. 6 to recognize and is usually between 1 ° and 30 °.
  • the conveying direction F lies in this middle plane.
  • the two Umfaltium 11 and 12 are equally arranged symmetrically to said center plane.
  • the angle ⁇ is in Fig. 5 registered; it is preferably between 15 ° and 40 °.
  • a centering cone 22 is arranged on a support arm, which is arranged in the center plane and the edges of the expiring and refolded film sections 5 again fixed and stabilized.
  • an essential aspect of the invention is that, during the reeling of the film sections 5 on the winding devices (not shown), both the knives 4 and the folding devices 6 oscillate in the direction Q transverse to the conveying direction F relative to the winding devices and to be moved.
  • 6 synchronization means 9, 10, 20 are present between the knives 4 or these supporting devices and the Umfalt wornen.
  • These synchronization means are in the embodiment of the FIGS. 1 . 2 . 3 . 5 and 6 from a pin 9, which is fixed on the support plate 15, and the connecting element 20, which is connected to the knife 4.
  • the carrier plates 15 are connected to the oscillation drive 8 via the rail 9 '.
