Definitions

  • the coin may be guided past anumber of test probes which set up an alternating electro-magnetic fieldT By rolling into this electro-magnetic field, the coil alters the impedance of the probes.
  • the size and/or material of the coin can be sensed by the probes.
  • the running channels in the coin testing apparatus must be adjusted to take the largest coin to be tested, small coins may pass the test means in an uncontrolled manner.
  • the results of the test are materially influenced by the smooth running and the precise position and speed of the coin in relation to the probes. For accurate recognition of the coin by the probes it is important to allow the coins to be investigated to pass the test means in a controlled manner.
  • the test means should test the shape of the edges of the coin.
  • test probes may be arranged to lie opposite one another in pairs of both sides of the coin track. One of each pair is to be regarded as the primary coil and the other as the secondary coil.
  • the test probes have an inner ferrite core on which the coil is wound. The winding itself is surrounded by ferrite shell cores which are embedded in or surrounded by plastic.
  • the voltage induced by the coin in the secondary coil is used to test the coin. Because of the large air gap existing for the magnetic flux between the primary and secondary shell cores, the field leaks very greatly, especially to the edges of the shell cores facing the coin track. In general, this leakage field flows around the coin and thus relatively diminishes the influence of the COll'l.
  • the object of the invention is to construct a coin testing apparatus in which the position and speed of the coin with respect to the test probes is controlled in order to improve the accuracy of the testing.
  • a further object of the present invention is to provide a coin testing device comprising a coin slot, a coin track leading from said slot, coin test means, coin guide means which together with said coin track define a coin path extending past said test means, and means, provided between said slot and said test means, for damping the rolling movement ofa coin along said coin path.
  • the damping device may comprise a lever, rotatable about an axis normal to the coin track, on one end of which, in the vicinity of the running surface, is a roller rotatable about its own axis, which partly projects into the coin track and on which the coin impacts, deflecting the lever, and on the other end of which is arranged a counter weight approximately equal to the weight of the roller, so that the lever together with the roller and counter weight returns to its position of rest after deflection by the coin.
  • the lever is with advantage formed in such a way that it has two arms unequal in length and forming an obtuse angle with one another, with the bisector of the angle pointing in the direction of the running surface, and the roller is fixed to the longer, downward pointing arm whilst the counter weight is fixed to the other shorter arm.
  • a ring of soft, elastic synthetic material e.g. soft rubber, may be placed around the edge of the roller, to which it is firmly attached.
  • the half of the roller projecting into the coin track is then with advantage bevelled like the frustum of a cone so as to support the movement of the coin to the running surface.
  • the plane in which the track lies is slightly inclined to the vertical for good guidance of the coin, so that the coin rolls on the running surface and slides along the guiding surface.
  • the coin track inside the coin testing apparatus slopes sharply downwards directly behind the slot openings, flattens out underneath the roller and behind the roller passes into a gradual slope to the test means.
  • the angle between the running surface and the guiding surface is at the beginning of the running surface and about 45 at the test means.
  • test means themselves may be test probes which have a ferrite core inside and ferrite shell cores around the winding, and having a ring of metal which conducts electricity placed around the ferrite shell and serving as a short-circuit coil placed flush against the surface of the test probe facing the running surface of the coin. It is not necessary for the axial extension of the ring to have the same measurement as the test probe; the thickness of the ring can also be about 1/4 to N2 the length of a probe.
  • test probes are inserted in the wall of the guiding surface and in the wall lying opposite to the guiding surface in such a way that the surface of each wall facing the coin track and that of the probe with the ring lie in one plane.
  • Each probe is cast in the wall by means of cast resin.
  • the track with running surface and guiding surface can be made altogether from electrically conducting material, for example metal, the test probe is inserted in a bore in both walls corresponding to its outer diameter and secured with cast resin so that both walls themselves serve as short-circuit windings for each test probe.
  • the following arrangement also has the same effect as a metal ring acting as a short-circuit winding: instead of making the boundary walls of the coin track and the track itself from plastic a material which conducts electricity, for example metal, can be used for this as well.
  • a material which conducts electricity for example metal
  • the ferrite shell cores of each test probe are fixed in walls in such a way that the latter directly clasp them and thus function as short-circuit windings.
  • a field opposed to the leakage field of the test probe which strongly bunches the latter is set up by the currents produced in the metal walls.
  • a coin testing apparatus of metal has further advatanges in that such an apparatus, compared with one made from plastic, has greater dimensional stability and therefore greater accuracy in measurement and greater rigidity in respect of outside shocks.
  • the roller fixed to the lever absorbs a large amount of the energy of a coin on impart with the roller, and guides the coin part of the way through the coin testing apparatus so that it is I led to the probes by the most favourable way.
  • the coin impacts with the roller, because of the soft rubber, it rebounds elastically and loses its energy and presses the roller or the lever upwards, running slowly beneath the roller. As soon as it is no longer in contact with the roller, it continues to run along the track which curves towards the test probe.
  • the guiding surface which runs parallel to the plane of the track, forms with the running surface an angle which decreases from 90 at the slot opening to the test probes.
  • the edge of the coin thus forms with the running surface an angle which increases along the track.
  • thin coins slide deeper in the region of the probe than thick ones; on the other hand, sharp-edge coins lie higher than coins with rounded edges.
  • the extent of the variation in the angle of the curving track to the running surface depends on the one hand on the desired influence of the thickness of the coin but on the other hand also on the friction of the coin permissible in the region of the probe. With a suitable test probe arrangement, the height of the top edge of the coin affects the result of the measurement very perceptibly.
  • FIG. 1 shows the track of a coin with a side view of one embodiment of a damping device and test probe according to the invention.
  • FIG. 2 is a section through A-A of FIG. 1;
  • FIG. 3 is a section through 8-8 of FIG. 1;
  • FIG. 4 is a section through CC of Flg. 1 to an enlarged scale
  • FIG. 5 is a cross-sectional view of the roller.
  • a coin testing apparatus in which coins are inserted from above through a slot which is not shown, has a running surface 1 with a section la in a plane falling almost vertically, an upward curved section lb and a section It inclined obliquely to the horizontal.
  • This track I has a guiding surface 2 and running surface 20.
  • a damping device 3 for coins 4 inserted from above in the coin slot Above the track is a damping device 3 for coins 4 inserted from above in the coin slot.
  • the clamping device 3 consists of a lever 5 with a long arm 6 and a short arm 7. The arms are inclined to each other at an obtuse angle with the bisector of the angle pointing to the track 1.
  • Lever 5 can rotate around axis 8 which is normal to the plane of the track.
  • a roller 9 At the free end of the short arm 7 of lever 5 is a counter weight 11.
  • Counter weight 11 is so designed that the lever system is in equilibrium when it is approximately in the position shown in the drawing. Furthermore, the moment of roller 9 about axis 8 is only slightly larger than the moment of counter weight 11 about axis 8.
  • Roller 9 shown in cross-section in FIG. 5, is constructed as a disc with a soft rubber tire 12 on its rim.
  • This tire 12 is bevelled like the frustum of a cone on the side which projects into the track of the coin.
  • the roller itself consists of plastic. Instead of rubber, any other soft, elastic synthetic material can be used for the tire
  • At the end of track 1 are located two test probes 13 past which the coin rolls.
  • Such a test probe 13 consists of a ferrite shell core 16 which contains the winding 15, which is preferably of copper wire. Coil 15 with the ferrite shell core 16 is inserted into the wall 2 of the guiding surface in such a way that the surface which faces the track of the coin is flush with the guiding surface.
  • a metal ring 18 of material which conducts electricity is inserted between plastic boring l7 and ferrite shell core 16; the leakage field about the two test probes which lie opposite to one another, of which one functions as primary coil and the other, as secondary coil, sets up currents in the metal ring which in their turn produce a field which is in opposition to the leakage field.
  • the composite field of leakage field and opposing field is strongly bunched.
  • the two test probes lying opposite to one another are accordingly fixed one in the wall of the guiding surface and the other in a wall 20 bounding the track on the opposite side.
  • the wall of the guiding surface and also the track boundary wall on the opposite side on which, the running surface is formed and the running surface itself can be made from the metal as used for the metal ring 18 (FIG. 1).
  • the wall of the guiding surface directly clasps the ferrite shell cores and thus acts as a short-circuit winding.
  • the mode of operation of this arrangement is practically identical with the mode of operation of the metal ring around the ferrite shell cores.
  • the test probe together with the metal ring may be cast and thus fixed with a mouldable, hardening plastic 19, for example cast resin, in the bore of the wall of the guiding surface and in that of the opposite boundary wall, whether of metal or plastic.
  • a lug (not shown) can be formed in the wall bore so as to fit into one of the gaps in the periphery of the shell core.
  • the coin After the roller has left the way free, the coin continues to roll and enters the zone of the test probes 13 at approximately the same speed. In order for the movement of the coin to be strongly damped down, it rolls very slowly around the roller and the speed at which the coin enters the alternating electro-magnetic field of the test probes is approximately equal for coins of equal size.
  • the running surface begins to tilt slightly at the start.
  • the running surface is only slightly inclined in relation to the guiding surface; it is much more inclined in Section BB and in Section C-C, which is at the level of the test probes, the inclination amounts to, for example, about 45.
  • the tilt ie the inclination of the running surface in relation to the guiding surface, which forms a decreasing acute angle with the latter, the width of the coin as well as the rounding of the edge can be established.
  • a thick coin lies higher in the region of the probe than a thin one or a coin with rounded edges. This height of the top edge of the coin enters very precisely into the result of the measurement according to the arrangement of the test probes.
  • a damping device in accordance with the invention is advantageous in any coin testing apparatus without the running surface of just that test apparatus needing to be twisted.
  • a coin testing apparatus can be especially advantageous in its operation.
  • a coin chute comprising a coin slot, coin test means that can help distinguish between a moving acceptable coin and a moving unacceptable coin of approximately equal size if said acceptable coin and said unacceptable coin move through essentially the same predetermined area at relatively slow speeds as they move past said coin test means, a coin track leading from said coin slot toward said coin test means, said coin track helping define a coin path which extends past said coin test means and which includes said predetermind area, and damping means, provided be tween said coin slot and said coin test means, which has a coin-receiving portion thereof that normally is spaced from said coin track a distance substantially shorter than the diameter of the smallest diameter acceptable coin to be tested by said coin test means but that can respond to movement of said acceptable coin along said coin path to move far enough away from said coin track to enable said acceptable coin to pass between it and said coin track, said damping means including a lever pivotally mounted above said coin track and a roller which is rotatably mounted on one end of said lever and which has a portion of the periphery thereof projecting into
