  • Equipment for storing in an orderly way banknotes and/or papers and the like
    Patent number: 8033542
    Abstract: An equipment (43) for storing in an orderly way banknotes (52) and/or papers and the like, for instance banknotes (52) for an automatic machine (39), provided for the formation of a stack (53). The equipment (43) comprises two spiral elements (81; 82) defining coils with respective axes (83; 84) directed in the sense of the stacking and terminal sections (86) adjacent to a stacking surface (77) at an end of the stack. The spiral elements (81; 82) are rotatable around the axes (83; 84) and are arranged for laterally receiving between the coils a leading portion of the entering banknote (52), moving the banknote (52), through the coils and in consequence of the rotation, on the stacking surface (77), and disengaging the banknote from the coils adjacent to the terminal section (86).

  • Method and device for forming a stack of packets
    Patent number: 7374392
    Abstract: A method and device for forming a stack of n packets, whereby the packets, fed successively in a substantially horizontal direction to an input of a substantially vertical conveyor channel, are stacked by being lifted, along the conveyor channel, by an n-start screw push device rotating about an axis substantially parallel to the conveyor channel; the stack so formed is extracted from an output of the conveyor channel, in a radial output direction with respect to the axis of the screw push device, by a comb extractor movable along an annular path extending through the conveyor channel.

  • Stacker for plate members, method for stacking plate members, and stacked plate members
    Patent number: 6984098
    Abstract: A stacker (10) for plate members includes a platform (15) on which plate members (20) are to be stacked and at least one pair of guides (11, 13) disposed at both sides of the platform (15) relative to a transferring direction of the plate members. Each of the guides (11, 13) has a ridge (12a, 14a) spirally formed on a rotational axial portion (12, 14) and a groove (12b, 14b) formed along the ridge (12a, 14a). The aforementioned at least one pair of guides (11, 13) are rotated with opposite edges of the plate member (20) engaged with the grooves (12b, 14b) of the guides (11, 13), to thereby move the plate member (20) toward the platform (15).
