  • Publication number: 20210272407
    Abstract: The banknote guiding device comprises a first, second and third guide assemblies, each guide assembly being rotatory to be placed in either a first or second position for the guiding of banknotes into channels, wherein the first and second guide assemblies are rotary about a first rotation axis, and the third guide assembly is rotary around a second rotation axis. It provides a banknote guiding device that is as simple as possible while minimizing the gaps between the guide assemblies to avoid banknote jams during travel.

  • Patent number: 10262487
    Abstract: A coin sensor comprising a first inductive branch with a first inductor in series with a first resistor; a second inductive branch with a second inductor in series with a second resistor, wherein the first and second inductors are arranged facing each other on both sides of a passage channel of coins to be discriminated; at least one capacitive branch with a condenser and a resistor in series; an excitation circuit with a generator and at least one pair of switches, configured to alternately feed the first inductive branch and the second inductive branch with a pattern signal with spectral energy in two or more frequencies, such that the branch of the inductor excited at any given time is arranged in a bridge configuration with at least one capacitive branch; at least one differential amplifier configured to alternately measure the voltage between the exit nodes of the excited bridge.

  • Patent number: 9076279
    Abstract: Coin conveyor for coin processing machines, with a channel having: a first coin (16) reception segment (1), defined by a longitudinally movable wall (5) and by an opposite fixed wall (10), both converging towards each other towards the inside of said channel; a second coin transportation and alignment segment (2), defined by a longitudinally movable wall (5), by an opposite fixed wall (10) and by an also fixed bottom (12); a third coin separation segment (3), defined by the lateral surface of a freely rotating cylindrical roller (14), by a longitudinally movable wall (5), by an opposite fixed wall (10) supported on the lateral surface of said cylindrical roller along the length of an arch of approximately 90°, and by a fixed bottom (12); and a fourth coin delivery segment (4), defined by a longitudinally movable wall (5) and by an also fixed bottom (12). The longitudinally movable wall (5) of all segments is constituted by a single endless belt being mounted on pulleys (6-6?).
