Definitions

  • the present invention relates to a method for extracting intermediate flat supports for stacks of products.
  • the invention relates to a method for extracting intermediate flat supports for stacks of cardboard cutouts arranged on pallets and the like.
  • stacks of cutouts such as for example those used to package cigarette packets of the rigid flip-top type.
  • These stacks of cutouts are generally arranged on a pallet-like support in multiple rows and in a plurality of layers that are separated from one another, in pairs, by an intermediate flat support constituted for example by a sheet of paper of appropriate thickness.
  • These devices pick up the stacks of cutouts in an orderly fashion and then transfer them to an inlet of a user machine.
  • Said grip means are capable of moving between a position for picking up the intermediate flat supports and a position for releasing said intermediate flat supports inside a collecting container.
  • the suction of the suckers also affects the cutouts arranged at the regions where said suckers are applied.
  • the lifting of the flat support tends to produce, with known extraction devices, a movement of the cutouts located at the top of the stacks with respect to the lower ones, due to adhesion between said flat support and said cutouts.
  • a principal aim of the present invention is to provide an extraction method that allows to eliminate the above-described drawback, extracting the intermediate flat supports without interfering with the stacks of products.
  • a method for extracting intermediate flat supports of stacks of products characterized in that it comprises the steps of: moving a grip element above a flat support to be extracted; activating presser means, carried by said grip element, to act on the stacks lying below said flat support, by virtue of the interposition of said flat support; lifting said flat support, at its peripheral region, by virtue of suction means carried by said grip element, and deactivating said presser means; and moving said grip element to place said grip element at means for collecting said extracted flat support.
  • the step of moving said element above said flat support to be extracted is performed by moving said suction means into contact with said flat support.
  • the reference numeral 1 designates a device for extracting intermediate flat supports 2 for stacks 3 of cutouts, such as for example those used to package cigarette packets of the rigid type.
  • the stacks 3 of cutouts are arranged in an orderly fashion on pallet-like supporting means 4.
  • the stacks 3 of cutouts are arranged so as to form superimposed layers 5 that are separated from one another by virtue of the intermediate flat supports 2, which are made of flexible material, for example paper.
  • the extraction device 1 includes a vertical framework 6 provided with a container 7 for collecting the extracted flat supports 2.
  • Said framework 6 is provided, in a substantially median position, with a bracket 8, and an arm 10 which oscillates on a vertical plane is pivoted to said bracket 8 by means of a pivot 9 having a horizontal axis.
  • the arm 10 is actuatable, by means of a crank 11, by a jack 12 that is pivoted to said framework 6.
  • a grip element 14 is articulated to the free end of the oscillating arm 10 by means of a pivot 13 having a horizontal axis.
  • Said grip element 14 comprises a frame 15 provided with suction means 16 that are constituted for example by a plurality of suckers 16 adapted to be connected to appropriate known suction devices, which are not shown in the figure.
  • the grip element 14 is furthermore provided, on the same side as the suckers 16, with a plurality of presser elements 17 that are actuatable by respective actuators 18 along axes that are perpendicular to the frame 15.
  • the suckers 16 are arranged at opposite ends of the frame 15, so as to act at the peripheral region of the flat support 2 to be extracted, while the pressers 17 are arranged in a central region of said frame 15.
  • the method for extracting the intermediate flat supports 2 entails a first step during which, by rotating the oscillating arm 10, actuated by the jack 12, the frame 15 is placed above the flat support 2 to be extracted so that the suckers 16 are arranged in contact with said flat support 2.
  • presser elements 17 are actuated by the actuators 18. Said pressers 17 act on the stacks 3 that lie below the flat support 2 to be extracted, by virtue of the interposition of said flat support 2, in order to apply a constant pressure that is directed towards the pallet 4 and is capable of blocking said stacks 3.
