  • Patent number: 7553223
    Abstract: A coin sorter has a separator strip disposed outside of an exit area of a stationary plate in which a line of coins of mixed denominations are indexed against a spirally extending ridge in a single layer and single file. The strip has a series of incremental segments defined in a side facing the center of a resilient disc which enables the coins to be captured. An edge area of the strip is configured to immediately re-capture coins as they are released at the exit area and to hold the coins until they pass by a segment of the strip that is far enough away from the indexing line of the coins that they are no longer captured, but are freely released. The released coins then proceed outward along a specific path defined for a particular coin denomination.

  • Patent number: 6758736
    Abstract: A coin or token sorting apparatus is disclosed. In this apparatus, a hopper within which coins are placed is provided with a floor, the floor also serving as a dispenser for spreading the coins out in generally across the floor. From one side of the floor the coins are provided to a plurality of V-shaped troughs being bisected longitudinally so as to create a coin path down each inner side of each trough. Coins are oriented in a single file as they move down each side of a respective trough. After being so oriented, the coins enter a region of a respective trough having a slot in a bottom thereof, with the coins riding along a narrow ridge of the slot. For each diameter of coin or token, a diverter is provided along the slot so that a coin to be sorted engages the diverter and is lifted off the ridge and directed through the slot. As such, larger coins are sorted first, with smaller coins moving unaffected past a diverter for a larger coin.

  • Patent number: 6017270
    Abstract: A coin sorter wherein there area plurality of side-by-side V-shaped, elongated tracks. These tracks are on a slope and are fed from a common coin feeder and the tracks are terminated at lower ends by coin diverters varied in configuration to progressively divert, and thus sort coins in a descending order of diameter.

  • Patent number: 5538468
    Abstract: A coin sorting apparatus receives coins through an opening in a guide plate onto the resilient surface of a rotating disc. The surface of the guide plate is contoured and includes portions positioned sufficiently close to the surface of the disc to press coins traveling therebetween into the resilient surface of the disc. As the coins are circulated circumferentially between the discs, the countours in the guide plate guide the coin into a single file along a first prescribed path. Coins of at least one selected denomination are displaced to follow a second prescribed path. The coins are discharged along each described path at exit locations at the periphery of the plate.

  • Patent number: 5080633
    Abstract: A coin sorting apparatus counts and sorts coins by denomination in an efficient manner. The steps involve receiving the coins on a disc having a resilient surface and imparting rotational movement to the coins by rotating the disc with a stationary guide plate having a contoured surface spaced slightly over the resilient surface of the disc. The guide plate includes a recess for guiding the coins on the disc into a single file of coins. A referencing portion of the contoured surface is used to guide one edge of the coins in the single file along a prescribed path. The coins of a selected denomination are then counted as they are moved along the prescribed path. Coins of different denominations are discharged at different locations around the periphery of the stationary guide plate, and, in response to the counting, the discharge of the coins is interrupted.

  • Patent number: 5022889
    Abstract: A coin sorter in which a sorting head is positioned over a rotating pliable disc and wherein coins are sorted by the combination of an inwardly or outwardly extending tapered edge and a series of pins generally positioned in an outwardly extending line spaced from the tapered edge. The spacing between the line of pins and tapered edge changes with radial dimension, whereby coins of different diameter are urged over the tapered edge by pins at different positions. The coins are then captured between the head and pliable disc and rotated to exit positions which are unique for each coin about the outside of the sorting head.

  • Patent number: 4564036
    Abstract: The invention relates to a coin sorter apparatus for sorting a group of mixed coins by denomination and terminating the sorting process when a predetermined number of coins have been sorted. A stationary disk provides a means for guiding the outwardly radial movement of coins rotating on the surface of a rotating disk from a starting point at the center of the stationary disk to an exit at selected areas at the periphery of the stationary disk. The radial positions of the coins are controlled so as to cause the coins exiting at the selected areas to be sorted by coin denomination. Sensors located proximate to these selected areas count the number of coins exiting at each area.

  • Patent number: 4549561
    Abstract: A coin sorter is provided comprising a rotatable disc with a resilient surface and a stationary disc having its first surface positioned proximate to the resilient surface of the rotatable disc. Coins placed between the two disc surfaces are pressed into the resilient surface by pressure from the stationary disc. Selected areas of the stationary disc are recessed so as to release coins from their pressed engagement with the resilient surface and thereby allow radial movement of the released coins in response to centrifugal force. The selected areas of the stationary disc which are recessed, guide the coins along a path which results in each denomination of coin escaping from between the two discs at different positions along the periphery of the stationary disc. Recesses and ridges are provided on the underside of the stationary disc which recirculate improperly aligned coins.

  • Patent number: 4444212
    Abstract: A coin sorting machine in which coins are fed onto the center of a rotating disc having a flexible surface. An annular guide plate is positioned over the disc, being open in the center for receiving coins, and extending outward to the peripheral edge of the disc. The underside of the guide plate is formed with a peripheral stop extending around approximately half of the disc, and a series of discrete radial guides extend over portions of the other half of the disc. The first of the series of guides would have an outer edge differing in radius from the peripheral stop by the diameter of the smallest coin to be sorted, and each succeeding guide would have a progressively smaller radiused outside edge defined by the difference between coins to be sorted by succeeding guides.
