Definitions

the invention relates to a device for testing coins with a inductively operating sensor arrangement according to claim 1.
Inductive measuring arrangements for coin validators usually use one Transmitter coil and on the opposite side of the coin track a receiver coil. As the coin passes through the magnetic field, it becomes the receiving coil damped. Since the magnetic field must penetrate the entire coin, it is not possible to detect inhomogeneities in the material depth of the coin. So can For example, if the magnetic moment is determined for a particular coin, not, however, whether the magnetic layer is on the surface or in the middle located in the coin. A similar problem arises with plated coins. Because only A total attenuation is measured, it can not be determined if it is homogeneous material or plated coins.
the invention is based on the object, a device for checking coins with a sufficiently high resolution measurement over the thickness of the Coin is allowed away without leaving any gap fluctuations of the coin particularly disadvantageous.
the invention sees the arrangement of the receiver coil on the same side as the Transmitting coil before, wherein the cross section of the preferably smaller receiving coil of a homogeneous magnetic field portion of the transmitting coil traversed by the coin is flooded.
receive and Transmitting coil arranged on the same side.
a relatively good insensitivity against uneven running of the coins is achieved in that the receiving coil in is essentially flooded by a homogeneous field of the transmitting coil. It is Consequently, to choose a coil arrangement, with which this requirement is met. at In this coil arrangement, the magnetic field in the center of the coil occurs approximately vertically to the core off and on and the magnetic field lines curl only in relatively large Distance from the surface of the core.
An arrangement according to the invention for testing coins sees the arrangement a transmitting coil on a ferrite core whose length is greater than the length of the Kitchen sink.
the receiver coil has a smaller diameter and is on one side of the ferrite core arranged coaxially so as to be separated from a homogeneous field Flood coil is flooded.
the receiving coil is located in an end-side Ring recess of the core, in particular the ferrite core.
a further receiving coil on the opposite Side of Münzlaufbahn arranged, which of the magnetic field of the transmitting coil, which penetrates the coin, is flooded.
FIG. 1 three examples of the cross section of coins are indicated. Under 1. is a plated or galvanized coin shown d. H. on both sides with one Layer is provided. In the middle example, a homogeneous coin is indicated, the z. B. brass, iron or a Kupfernickellegtechnik. In the example below is a so-called layer coin represented with a nickel core and outer Layers of copper / nickel alloy. With the help of the invention such Coins are discriminated against.
FIG. 2 shows a ferrite core 10 in section, on the outside of a transmitting coil 12th is applied.
the length of the ferrite core 10 is significantly larger than that of the transmitting coil 12, d. H. is nearly four times the coil length.
the transmitting coil 12 is in Distance from the ends of the ferrite core 10 is arranged.
a receiving coil 16 is arranged in an annular recess 14 at one end of the ferrite core 10. It is coaxial to the transmitting coil 12, but has a much smaller inner and outer diameter as the transmitting coil 12.
With 18 a plane is indicated, in which usually one Coin moves in a coin validator along. The annular recess is thus the plane 18 turned.
the running direction of the coins is approximately in the direction of arrow 20.
the magnetic field lines generated by the transmitting coil 12 are shown in dashed lines. In the region of the receiving coil 16, the magnetic field is largely homogeneous. So it is the receiving coil 16 flowing through and the coin in the measurement plane 18 acting Magnetic field largely homogeneous. A divergence of the magnetic lines, as indicated at 22, takes place at a greater distance from the coil assembly.
the method for testing coins with the coil arrangement according to FIG. 2 is intended not described. It can proceed, for example, according to methods, as in DE 197 26 449 described.
