  • Patent number: 5496211
    Abstract: A device for vertically conveying coins including a lower horizontal guide path, a vertical guide path, an approximately arc-shaped deflecting path connecting the lower horizontal guide path and the vertical guide path. Each of the path conveys the coins in a lying fiat position. At least one conveyor belt is provided. Rollers are provided whereby the conveyor belt is led around the rollers. Deflecting rollers are arranged at space locations from the guide paths and the from the arc-shaped deflecting path. With this structure, an essentially constant conveying gap is formed by the thickness of the coins being conveyed between the guide paths and the deflecting paths and the conveyor belt. Structure for feeding the coins, conveyed lying flat one by one, is arranged at the beginning of the lower horizontal guide path. Structure for transferring the coins being conveyed is arranged at the top end of the vertical guide path.

  • Patent number: 4951448
    Abstract: This invention refers to a mechanism for the production of rolls of coins, with a feeding track for horizontal coins. A tilting station is provided to put the coin into an upright position, and a wrapping station is provided to form rolls of coins out of the stacks of vertical coins.In order to increase the amount of coins to be gathered into stacks of coins and wrapped as rolls of coins, per time unit, and in order to reduce the size of the mechanism the invention provides a tilting station consisting of two parallel tracks which connect to a feeding track. The parallel tracks are spaced a distance from each other which is slightly less than the diameter of the coins. A coin retainer is provided with an angled surface spanning the transportation direction of the coins. The coin retainer is mounted so that it can be swivelled against the transportation direction of the coins.

  • Patent number: 4681204
    Abstract: A device for counting and sorting coins belonging to a set of coins with a guideway 8 tangentially connected to a horizontal coin plate 3 is to be developed for separating foreign coins 11' through a sort-out opening 16. To this end, and behind a coin identifying device 14 and immediately in front of the sort-out opening 16, a diversion element 18 is movably arranged for the coins 11' identified as foreign or counterfeit coins by the coin identification device 14, with its front edge 35 arranged at a distance of at least the width of guide rail 17 from the guiding edge 9, with the diversion element 18 able to be triggered by the coin identification device 14. The diversion element 18, which in its active position is brought into the path of movement of coins 11, 11', diverts the coins from guiding edge 9 by at least a distance that is equal to or greater than the width of guide rail 17. In this manner, the foreign coins 11' to be separated out can drop through the sort-out opening 16.

  • Patent number: 4657035
    Abstract: An improved device for separating out single coins from a collective plurality of coins solves the problem of separating stacked coins, namely two or three coins lying one upon the other with their total thickness being smaller than or equal to that of the thickest coin. In accordance with the device, to separate the coins, a second coin stripping arm (15) embodied by a narrow and thin guide finger (16) is provided downstream of a first coin stripper (14), considered in the direction of rotation (Arrow 5) of the coin disc (3), the first coin stripper (14) being adjusted to the thickness of the thickest coin, and the guide finger (16) projecting beyond the disc outer edge and guiding the respective underlying coins (11) on the coin disc (3) directly into a guideway (8) above which a first conveyor belt (12) is disposed.

  • Patent number: 4178502
    Abstract: A device for counting coins of different diameters and similar disk-shaped objects which are conveyed in irregular sequence. The edges of the coins contact a guide edge on a guide track which has a scanning head located therein for identifying the coins. An electronic evaluation and display unit receives the identification signals delivered by the scanning head. The scanning head has several electronic proximity sensors located at different distances from the guide edge. The paths of motion of the edges of coins away from the guide edge, run in the active areas of the proximity sensors which provide substantially clear identification signals distinguishing the coins to be identified. The diameter of the proximity sensors is approximately half the diameter of the smallest coin to be identified, and the several proximity sensors are located at different distances from the guide edge. These distances are determined by the paths of motion of different coins.

  • Patent number: 4088144
    Abstract: An arrangement for counting the values of different-denomination coins and other disk-shaped objects in which the coins are transported in an irregular sequence with their rims along a rectilinear guiding edge on a guide track. A scanning head identifies the coin, and is located at the start of the rectilinear guiding edge. The scanning head has several photoconductor strands having free ends located at varying distances from the guiding edge. Photocells are connected to the other ends of the strands, and a light-beam element illuminates the free ends of the photoconductor strands. The photoconductor strands and the light-beam element are separated by a scanning gap for passage of the coins. The photoconductor strands are located along a line perpendicular to the guiding edge inside a holder which is inserted in the guide track. The free ends of the photoconductor strands are flush with the surface of the guide track. One photoconductor strand is associated with each of the coins of varying diameter.
