Definitions

  • the present invention relates to a winder according to the preamble of claims 1, 8 and 12.
  • plastic films are produced in an extraordinary variety of compositions and correspondingly with a wide variety of properties, which then also influence the winding behavior and must be considered accordingly in the winding.
  • the respective production speed and the number of coils to be produced in a production run are parameters which must be taken into account for a qualitatively sufficient production with at the same time reasonable costs.
  • Typical processing speeds range from 2 to 1000 m / min, while the finished wound bales may have a diameter of 50 to 2000 mm and a width of 10 to 6000 mm, respectively.
  • the thicknesses can range from a few ⁇ m down to the millimeter range.
  • films having a thickness of 8 microns to 25 microns.
  • polyolefins such as PE polyethylene or PP polypropylene
  • the formulation of particular plastic films of polyolefins ranges from the mono-extruded film, consisting of a single layer, to the coextruded film with three, five or more layers, wherein, for example, adhesives of various types can be provided in the layers , as many different multilayer films arise.
  • the adhesive contained between the plastic layers of the films ensures that the individual windings adhere to one another around the grass bale, so that the winding has stability.
  • the bale of grass is formed, when the film is unwound from the wrapping, a typical, scratching sound is produced which, depending on the adhesive, is louder or quieter.
  • Various farms require quietly releasing films, which has a corresponding influence on the overall recipe of the film.
  • the production varies between the production of only a few identical wound bales for special applications up to the mass production of the same wound bales.
  • the films themselves have different properties, which in turn must be taken into account in the winding for faultless film winding, which makes special demands on the winder parameters such as web tension, winding pressure, speed and film thickness and elasticity of the film.
  • Error-free winding taking into account the parameters mentioned above is also essential because with different formulations the finished wound film (the winder is usually immediately downstream of the extruder producing the film) still lives, since the different plastic layers still calm and the between the Layers of trapped air or introduced substances, often the adhesives, change and also through the layers migrate. In other words, the process of producing the films after winding is not yet completed. Not absolutely perfect winding can therefore happen that a roll later, during storage, negatively changed and unusable.
  • FIG. 1a shows by way of example a winder 1 according to the prior art in a side view, which represents the path of the endless material web, here a plastic film 2, through the winder 1 therethrough.
  • a separate scraping unit 3 for scrap film is followed by a cutting unit 4, which separates the endless film 2 lengthwise, so that two separate film webs or films 5 and 5 'are formed, each of the films 5,5' for the winding in a associated turret unit 6,6 'is performed.
  • the turret assemblies 6,6 ' are basically the same structure and each have three winding shafts in the illustrated embodiment, namely a first winding shaft 10,10', a second winding shaft 11,11 'and a third winding shaft 12,12'.
  • the winding shafts 10, 10 'to 12, 12' are located in different work stations, namely a charging station 13, 13 ', a winding station 14, 14' and a removal station 15, 15 '.
  • the revolver units 6, 6 'thus form a means for supporting the reel 18, 18' to be wound, here as follows:
  • Each of the winding shafts 10,10 'to 12,12' passes in the cycle the charging station 13,13 ', where it is loaded with fresh cores passes through a further rotation step of the turret units 6,6' in the winding station 14,14 ', where the winding cores 17 are wound with the film 2 to a winding 18 and from there into the removal station 15,15 ', where the winding 18 are removed from the turret unit 6,6'.
  • the figure shows a finished roll 18 in the winding station 14 and a just wound winding 18 'in the winding station 18'.
  • FIG. 1a shows a section of the winder 1, namely the winding station 14 and the contact roller 19 including their storage, again seen from the side.
  • the contact roller 19 is suspended from two laterally acting pendulum arms 20 and is thus pivotable about a pivot axis 21.
  • the pendulum arms 20 allow the contact roller 19 a movement in the direction of the arrows drawn so that they can always mitwandern with the growing diameter of the coil 18 (in the present arrangement, the winding core on which the film 5 is wound, fixedly mounted).
  • a pressing unit, here a piston arrangement 23, ensures the contact pressure of the contact roller 19 corresponding to the formulation against the winding 18.
  • the film 5 runs during operation of the winder 1 via an auxiliary roll 25 and from there to the contact roller 19, where it is pressed in the contact line 26 to the winding 18 and wound on this.
  • This ensures that the film 5 between the auxiliary roller 25 and the contact roller 19 is free only over a short distance 27, which is advantageous: the sometimes quite fast running (see above to the feed speeds) film 5 calms down even before they at the location of the contact line 28 runs on the contact roller 19, which supports a fault-free winding.

  • Such a delay leads even with moderately sensitive formulations to an optically visible pattern in the wound film, and in the unfavorable case for wrinkling. Both means waste production.
  • FIG. 2a shows a three-dimensional view of the inside of a pendulum arm 20 in a preferred embodiment of the present invention, in which the contact roller 19 is suspended from pendulum arms 20, as shown in FIGS FIG. 1b is described.

  • the pendulum arms 20,31 pivot about their common pivot axis 21.
  • the two pendulum arms 20 via a pipe 35 and the other two pendulum arms 31 via a pipe 36 connected to each other, which ensures their synchronous movement.
  • the tubes 35,36 are arranged coaxially with each other and also to the pivot axis 21.
  • a machine control which controls the drives for the pendulum arms for the contact roller 19 and the other pendulum arms 31 for the auxiliary roll 30 operable.

Shown is a three-dimensional view on the outside of the one, in the FIG. 2a shown pendulum arm 20, here with a gear 37 which connects the pendulum arm 20 and the other pendulum arm 31 with each other.

  • the pendulum arm 20 and the further pendulum arm 31 are connected to each other, wherein the transmission 37 at a pivoting of the pendulum arm 20 (for example, by the cylinder assembly 23 of FIG. 2a ) generates a pivoting of the further pendulum arm 31.
