Definitions

  • the present invention relates to a new apparatus for handling, by unwinding, sheet products presented in rolls, and in particular, thin films of plastic material, generally stretchable, intended for the packaging and conditioning of the most diverse articles, by for example, large stacks of irregularly shaped objects, such as bottles, or stacks of irregularly shaped objects, such as books or boxes.
  • the rollers generally comprise a mandrel, most often made of cardboard, on which the film is wound, of variable width, very long and very thin, of the order of 0.25 microns.
  • This film is delicate and difficult to handle.
  • the operator fixes the end of the film at a starting point for the product, then wraps it in tight turns around the product, progressively unwinding it from roller.
  • the packaging is completed, the product is enclosed in a volume of film adhering to itself, constituting a packaging which is all the more solid as the film turns are tightened.
  • Such a tip is preferably molded in a single piece of plastic, and has an internal portion and an external portion, the first intended to be introduced elastically inside the cardboard sleeve and to serve as a pivot, the other intended to be taken in each hand by the operator.
  • the internal portion is in the form of a "tulip" and is in the form of two truncated cones joined by their large base, their junction having a diameter slightly greater than that of the sleeve, and hollowed out along several generatrices so as to be able to be tablets resiliently inward.
  • the external portion consists of a circular crown delimiting the most tapered of said truncated cones and having a diameter slightly greater than that of the sleeve, this crown being connected to a handling disc by a hollow zone flared outwards.
  • the present invention is an improvement to this device, intended to further reduce said efforts, by eliminating any actual friction, thanks to a pivoting part adapted to the end piece.
  • the end of the inner portion of the end piece has stops with triangular sections, making it possible to thread the ring on the end piece, by elastic deformation of this inner portion, but then immobilizing this ring axially, preventing it from escape during its rotation.
  • the nozzle 1 consists of a cylindrical inner portion 3, notched in 4-4 'along two diametrically opposite generatrices, creating two faces 5-5' facing each other and elastically deformable. These two sides are connected to an outer portion 6 in the form of a crown, intended to protrude outside the sleeve to be handled.
  • the ring 2 consists of a cylinder 8, of internal diameter substantially greater than that of the cylindrical portion 3, so as to be able to pivot freely on this portion, and external grooves 9, bringing the overall diameter of the ring to a value very slightly greater than the internal diameter of the sleeve of the roller.
  • the ring 2 is pressed on the end piece 1, so that, cooperating with the bevels of the stops 7-7 ′, it deforms inward the cylindrical faces 5-5 'and can come into place on the cylindrical portion 3.
  • the stops 7-7' then escape the ring, and the sides 5-5 'resume their position, the rear face of the stops 7-7' preventing the ring to escape from its place on the nozzle, as in figure 2.
  • the device shown and described above is only an embodiment, and may be subject to equivalent variants.
  • the number of notches 4 may be different from two, the external holding portion 6 may have a shape different from that of a simple disc, for example, having grip marks.
  • the ring may include other forms of immobilization elements in the sleeve, for example, pins or the like.
