Definitions

  • the invention relates to a device for checking and sorting coins of different denominations with a coin validator connected to a control unit with an outlet for permissible coins and with a sorting unit arranged downstream of the coin validator and having three flaps, which is controlled by the control unit in accordance with the coins detected , Electromagnets coupled with the flaps assign the coins to different coin channels leading to coin stacking tubes, whereby a first flap of the sorting unit can close two coin paths and the first flap is followed by a second and a third flap, each of which can be switched back and forth between two coin channels .
  • a coin validator which has six flaps to be operated. Three flaps in parallel switch between six coin channels, all three of which are actuated by an electromagnet. Above the three flaps lying in parallel, two flaps lying side by side are arranged, the three Through channels can release and each operated by an electromagnet. Again, a flap is provided that switches back and forth between a return channel and the coin channels.
  • This multichannel system is unsatisfactory insofar as the coins are forwarded through the flaps aversely or reversely, as a result of which the flaps are subject to increased wear due to the frictional sliding that occurs.
  • the six coin channels are so close to each other due to the above-mentioned mode of operation of the flaps that a direct transfer of the coins emerging from the coin channels into coin stack tubes that are individual to the coin value is not possible; be provided, which increase the construction volume.
  • DE 37 18 979 A1 discloses a device for checking and sorting coins of different types with sensors for detecting coin parameters, which are connected to an evaluation and control unit in which the reference coin parameters are stored.
  • the device has a three-flap sorting unit, which assigns the coins to different coin channels via electromagnets controlled by the control unit in accordance with the coins detected.
  • a first flap of the sorting unit can close two coin channels with the two additional adjacent coin channels assigned to the two coin channels, and the first flap is followed by a second and third flap, each of which can be switched back and forth between two coin channels, a slide with the third flap is connected, which can be pushed back and forth between the two coin channels that can be covered by the second flap when the third flap is actuated, in such a way that the slide covers one of the coin channels and forms a connection to the two other coin channels located next to it.
  • this device opens up six sorting options for coins of different values
  • the slide connected to the third flap requires a complicated mechanism which makes the device more expensive and makes it more difficult to assemble.
  • the coins are also deflected on their front or back by the flaps in this case, which due to the resulting sliding friction on the one hand leads to a relatively quick wear of the flaps and on the other hand to an increased fall-through time, which means that coins are inserted quickly one after the other the device complicates.
  • US-A-4 850 469 shows a coin sorting device in which a flap is designed in such a way that the coins roll up thereon over its periphery.
  • the invention has for its object to provide a device of the type mentioned, which allows a direct transfer of the coins issued by the sorting unit into the downstream, coin-value-specific coin stacking tubes with a compact structure, simple handling and high maintenance.
  • the individual flaps of the sorting unit are designed as guide levers which are pivotally mounted between a front wall and a rear wall of the sorting unit, the distance between the front wall and the rear wall of the sorting unit being somewhat larger than the greatest thickness an allowable coin and the guide levers are designed to be narrow so that the coins roll up over their periphery on the guide levers.
  • the outlet width of the coin channels of the sorting unit can be determined in such a way that the coin stack tubes arranged next to one another are located directly, ie without intermediate channels being interposed. can connect to the outputs of the coin channels of the sorting unit.
  • the control unit controls the flaps depending on a freely selectable assignment of coin types to the four coin channels that are present due to the three guide levers connected in series or next to one another.
  • the first guide lever is operatively connected to the armature of an electromagnet via a spring-loaded toggle lever articulated to its bearing.
  • the bearing of the first guide lever expediently comprises a bearing eye formed on the end thereof, which is attached to an axis on the rear wall of the sorting unit and is slidably supported by an axis extending through a recess in the front wall, and the bearing eye is in the region of the outside of the front wall with one protruding axle bearing approach provided which engages in an elongated hole of one leg of the knee lever.
  • the other leg of the toggle lever preferably ends above the armature of the electromagnet fastened to the outside of the front wall, and the toggle lever is mounted on an axis protruding from the front wall via a bearing eye located in the region of its angled portion.
  • a further, spring-loaded toggle lever is mounted via a bearing eye lying in the area of its angled portion, on one leg of which a two-armed transverse lever is articulated, which is articulated on the end eccentrically to the bearings of the second and third guide levers, and whose other leg is in operative connection with the armature of another electromagnet.
  • the two electromagnets are preferably accommodated opposite one another in a U-shaped holder attached to the front wall, the legs of which have mutually corresponding incisions for the passage of the toggle levers.
  • the bearings of the second and third guide levers expediently each comprise a bearing eye formed on the end of the corresponding guide lever, which is mounted on an axis fixed to the rear wall of the sorting unit and extending through a recess in the front wall, each bearing eye in the region of the outside of the front wall is provided with a projection bearing a protruding axis which slidably engages in a bearing eye of the cross lever.
  • the spring actuation of the rocker arms takes place in the direction of the armature of the electromagnets by a torsion spring pushed onto the bearing eye of the first rocker arm, the leg ends of which each overlap the arm of the rocker arm facing the armature of the electromagnets.
  • the entrance of the sorting unit corresponding to the exit of the coin validator is defined by two opposing boundary walls arranged between the front and the rear wall, the lower end of each serves as a stop for the free end of the first guide lever.
  • four adjacent guide levers are arranged under the two parallel guide levers, which can be actuated by a common electromagnet and which can release eight coin channels.
  • the coin stacking tubes arranged downstream of the coin channels of the sorting unit are each accommodated in a coin module with associated coin payment device, the coin modules being arranged interchangeably next to one another in a carrying holder are, which can be used in a pivoted frame hinged to the housing of the device.
  • the pivoting frame can expediently be locked in its pivoted-in position by means of a key lock.
  • the carrying holder has a U-shaped receiving part which is laterally articulated to a floor frame and the bottom of which is provided with incisions lying next to one another for receiving locking noses attached to the underside of the coin modules. So that the coin modules cannot be removed from the carrying holder without authorization, the receiving part can preferably be locked to the base frame by means of a key lock.
  • carrying handles are arranged on the free ends of the legs of the receiving part.
  • the device for checking and sorting different types of coins has a housing 1 with a side coin input 2, to which a downward-sloping coin passage 3 with two branches 4 running parallel to one another connects, each leading to a coin validator 5 for checking four different types of coins .
  • Each coin validator 5 is provided with a return button 6 for opening the coin validator 5 in order to feed coins jammed therein to a return exit 7.
  • the return button 6 is actuated via a controllable electric motor 8, which is coupled to the return buttons 6 via a worm gear 9 and a lever linkage 10.
  • the coins recognized as permissible by the coin validators 5 arrive at an acceptance exit 11.
  • the left coin validator 5 is for checking 0.01 DM, 0.02 DM, 0.05 DM and 0.5 DM coins designed, while the right coin validator is used to check 0.1 DM, 1.00 DM, 2.00 DM and 5.00 DM coins.
  • a separator 12 is installed in the coin passage 3 in front of its branches 4, which separator leads the coins into one or the other branch 4 depending on their size.
  • each of the two coin validators 5 there is a sorting unit 13, the input 14 of which corresponds to the acceptance output 11 of the assigned coin validator 5.
  • the coin validators 5 are connected to a control unit (not shown) in which signals issued by the coin validators via sensors are processed with regard to the value of accepted coins and which triggers certain sorting processes in the sorting units 13 depending on the result.
  • At the lower part of each sorting unit 13 there are four coin modules 15 located next to one another, each of which contains a coin stacking tube 16 with a coin payout device not shown above. Via conveyor belts (not shown), driven by an electric motor 17, the coins removed from the coin stacking tubes 16 and the coins recognized by the coin validators as inadmissible are passed into an output tray 18 arranged below the coin input 2.
