Definitions

  • the invention relates to a device for checking the authenticity of coins, tokens or other flat metallic objects of the type mentioned in the preamble of claim 1.
  • Such facilities are suitable, for example, as cashier stations in public telephone stations, vending machines, energy meters, etc.
  • a device for checking the authenticity of coins of the type mentioned in the preamble of claim 1 is known from EP 304 535 B1.
  • the device has three inductive sensors working independently of one another for determining the thickness, the alloy composition and the diameter of the coin to be tested.
  • These inductive sensors are designed as double coils, which are arranged on both sides of the coin channel and are electrically connected in parallel or in series, so that measurement variations due to the coin jumping or jumping in the coin channel can be partially compensated for, with bouncing and jumping lifting off the bottom of the coin channel or a change in the position with respect to the side walls of the coin channel is meant.
  • the use of double coils has the disadvantage that the alloy composition and the thickness of the coin cannot be determined independently of one another.
  • the inductive sensors are part of a parallel resonance circuit, in which the shift in the resonance frequency caused by the coin and the changed quality are measured. The measured changes in these parameters serve as decision criteria for the acceptance or rejection of the coin. It is also envisaged to design an inductive sensor for determining the alloy composition as a simple coil, which is attached only on one side of the coin channel.
  • a coin detector with inductive sensors which are operated at frequencies from 3 kHz to 1 MHz.
  • the inductive sensors are arranged in resonant circuits and in bridge circuits.
  • the resonance frequency in the presence of the coin is used to characterize the coin.
  • energy absorbing elements are known in order to achieve rolling without bouncing or jumping of the coin in the area of the sensors.
  • Such energy absorbing elements are preferably ceramic plates which are arranged in the coin channel in such a way that every coin thrown into the coin inlet opening impinges on them.
  • the invention has for its object to provide a device for checking the authenticity of coins, in which the alloy composition and the thickness of the coin can be determined independently of one another, in which a bouncing or jumping of the coin is firstly excluded as possible and secondly, remaining hopping or jumping leads to the smallest possible measurement spread.
  • the coin channel 1 shows a device for checking the authenticity of coins, tokens or other metallic objects with a coin channel 1, which is preferably formed as a recess in a body 2 made of two plastic parts.
  • the coin channel 1 is delimited by the base 3, a lower and an upper side wall 4 or 5 and a ceiling 6.
  • the lower side wall 4 is provided with integrally formed ribs 7 which are formed in the running direction of the coin M.
  • the coin channel 1 is inclined in the running direction of a coin M to be checked and the two side walls 4 and 5 are inclined at an acute angle of typically 10 ° with respect to the vertical V, so that the coin M to be checked rolls down the floor 3 along the coin channel 1 or slides down and ideally lies flat with one side surface on the ribs 7 of the lower side wall 4.
  • the side walls 4 and 5 each have recesses on the side facing away from the coin channel 1 for receiving staggered coils 9 and 10 and, optionally, metallic plates 11, 12.
  • the coil 9 and the plate 12 are located on the lower side wall 4, which is why they are shown in dashed lines. For the sake of clarity, the recesses are only shown in FIG. 2.
  • the plates 11 and 12 are mounted opposite the coils 9 and 10, respectively. They are preferably round or square, but can also have any other geometric shape.
  • Each coil 9, 10 and possibly the metallic plate 11 or 12 arranged in the opposite side wall 5 or 4 form an inductive sensor.
  • the two coils 9 and 10 have two connections, one of which is led to a common electrical ground connection m, the other to a switch 13, so that they can be connected to an electronic circuit 14 for electrically independent operation.
  • the device further contains a control and evaluation unit 15, for example in the form of a microprocessor, for evaluating the output signal supplied by the electronic circuit 14 and for controlling the device.
  • the circuit 14 and the microprocessor 15 are designed to derive discrete values from the signals measured with the coils 9 and 10, which values are a measure of the alloy or the thickness d of the coin M.
  • the coin M is only considered to be genuine and accepted by the test device if these values match predetermined values within predetermined tolerances, otherwise it is rejected.
  • the shape of its surface facing the coin channel 1 is cylindrical, its radius of curvature R being of comparable size to the distance a: R ⁇ a.
  • R 8 mm is preferred.
  • the ribs 7 are naturally separated by depressions 16, the depth of which is approximately 0.5 mm.
  • the depressions 16 have a flat surface 17 in the area of the greatest depth between the ribs 7, so that the side wall 4 has a minimal wall thickness in the area of the recesses 8, which is only to be expected due to the material properties of the body 2 and the coins M to be expected mechanical loads, but can be determined independently of the radius of curvature R and the distance a.
  • a minimum wall thickness of 0.6 mm is preferably provided, so that the coil 9 mounted in the recess 8 in the lower side wall 4 is at a fixed distance of 1.1 mm from an ideally rolling coin M.
  • the ribs 7 are also there to prevent unwanted sticking or even sticking of a wet coin.
  • the formation of the ribs 7 as cylindrical surfaces with a comparatively large radius of curvature R results in a larger contact surface between the lower side wall 4 and the coin M than is the case with ribs according to the prior art.
  • the radius of curvature R of which is smaller than the distance a and, for example, is only a / 2 can easily be determined by experiment. The shape does not have to be exactly that of a cylinder.
  • a plate parallel to the side wall 4 is loosely fixed in the lower side wall 4 in the area of the coils 9 and 10 instead of the ribs 7.
  • the plate has a comparatively small mass compared to the masses of the coins to be tested and consists e.g. made of metal or ceramic. It is used to absorb the energy of the jumping coin M if the coin strikes the plate and thereby dampens the jumping of the coin M.
  • a coil S means one of the coils 9 or 10.
  • the coil S is electrically characterized by its inductance L S and its ohmic internal resistance R S. It represents an inductive sensor.
  • the above-mentioned combination of the coil S with one of the plates 11 and 12 represents another inductive sensor.
  • the internal resistance R S contains a static component R S, DC and a dynamic component R S, AC ( ⁇ ), which depends on the angular frequency ⁇ of the current flowing through the coil S, of depends on the physical properties of the coin M, on the geometry of the coil S and, in particular, on the distance between the coil S and the coin M.
  • ⁇ angular frequency
  • the diameter of the coil S is selected to be smaller than the diameter of the smallest coin M to be measured and the coil S is on the side wall 4 or 5 of the coin channel 1 is arranged at an appropriate height, so that the smallest coin M to be tested briefly completely covers the coil S during the passage.
  • the diameter of the coil S is, for example, 14 mm.
  • the resistance of the lead wires is comparatively low.
  • Coils 9 and 10 are particularly suitable for wound coils with a ferrite core. The design of the coils 9 and 10 as single coils arranged on only one side of the coin channel 1 and their complete electrical isolation avoids the loss of sensitivity associated with double coils.
  • the electronic circuit 14 operates the coil S in a series resonance circuit and delivers at its output an analog signal which is proportional to the internal resistance R S of the coil S.
  • R S internal resistance
  • the microprocessor 15 uses an analog / digital converter as a sequence f1 of digital values.
  • the microprocessor 15 then carries out a detailed analysis, which is explained below, the result of which are two values, for example the values K 1 and K 2 described below, which are used to decide whether to accept or reject the M coin.
  • the coil 9 is located on the lower side wall 4, on which the coin M moves lying along, so that the distance between the coil 9 and the side surface of the coin M is fixed and is, for example, 1.1 mm.
  • the coin M is made of either a single alloy or several alloys.
  • the internal resistance R9 of the coil 9 measured in the presence of the coin M depends, with a suitable choice of the frequency ⁇ of the current flowing through the coil 9, almost exclusively on the material of the coin M. 3 shows the internal resistance R9 as a function of the thickness d of the coin M for coins made from various alloys L1, L2 and L3, the coin M being in a symmetrical position in front of the coil 9 during the measurement. From this it can be seen that the internal resistance R9 is practically independent of the thickness d. With the coil 9 is therefore an important first characteristic size of the coin M, which is almost exclusively from its Alloy or alloy composition depends, easily determinable.
  • the distance between the coil 10 and the coin M depends on its thickness d.
  • the internal resistance R10 thus depends not only on the material of the coin M, but also on its thickness d.
  • the dependence on the thickness d in the region of interest is approximately linear for all alloys L1, L2 and L3 shown. If the alloy of the coin M is known, the thickness d of the coin M can be clearly determined.
  • the use of the two coils 9 and 10 with or without platelets 11 and 12 as simple coils, which are only arranged on one side wall 4 and 5, respectively, which are arranged on both sides of the coin channel 1 and are electrical are connected in parallel or in series, the mutually independent determination of two parameters of the coin M, which characterize the coin M on the basis of its alloy or alloy composition or thickness.
  • the output signal of the coil 9 has two maxima M1 and M2 with values U1 and U2, the output signal of the coil 10 has two maxima ml and m2 with values v1 and v2.
  • the solid line represents the output signal of a coin M, which rolls down the coin channel 1 (FIG. 1) without hopping or jumping and lies flat on the ribs 7.
  • the dash-dotted line shows the output signal of a coin M which jumped or jumped in the measuring range of the first coil 9: the values U1 and U2 are different.
  • the dashed line shows the output signal of a coin M which jumped or jumped in the measuring range of the second coil 10: the values v1 and v2 are different.
  • Tests have shown that at least one of the values U1 or U2 or v1 or v2 is relatively stable, i.e. has a small scatter, whereas the minimum between the corresponding maxima is subject to a larger scatter.
  • the value of the larger of the two maxima corresponds to the smallest distance between the coil 9 and the coin M, since the damping of the coil 9 is then greatest.
  • this is the second maximum M2 with the value U2 for both lines, which is also the more stable of the two maxima.
  • the microprocessor 15 is therefore programmed to determine the greatest value of the output signal at the first coil 9 and to store it as the value K 1.
  • the damping of the second coil 10 is smaller, the greater the distance between the coil 10 and the coin M.
  • This described analysis of the output signals is carried out by the microprocessor 15 in a manner known per se by.
  • the greatest value of the output signal of the first coil 9 can be determined by numerical comparisons, the maxima m1 and m2 can be determined by forming the first and second derivatives of the sequence f2.
  • the reference resistors r1 and r2 are advantageously determined each time immediately before or after the passage of the coin M.
  • each coin M has two differently minted sides, which are called head and number in German.
  • This asymmetrical coinage of the coin M leads to the fact that the characteristic sizes K 1 and K 2 determined with the coin M depend on the side with which the coin M rests on the side wall 4.
  • the scatter of the sizes K1 and K2 available for a certain coin type is further increased by this effect.
  • the range of the size K 1 remains sufficiently small to be able to clearly determine the alloy of the coin M.
  • the measurement of the thickness d is disturbed by this effect to an extent that makes it difficult to assess the authenticity of the coin M and / or to determine its value, since coins of different values made from the same alloy often differ very little in thickness.
  • the effect of this effect on the determination of the thickness d can be reduced.
  • the measurements of the coils 9 and 10 give e.g. a value K1 and a value K2. If the coin M has an asymmetrical embossing and its head side faces the coil 9, the measurements give slightly changed values K1 + ⁇ r1 and K2 - ⁇ r2.
  • An increase in the size K 1 leads to a decrease in the size K 2, since a reduction in the distance between the coil 9 and the coin M results in an increase in the distance between the coin M and the coil 10.
  • Fig. 3 shows that the measured values K1 differ significantly for different alloys.
  • the alloy of the coin M is thus comparatively easy to determine, ie the tolerance values that indicate whether the coin M is accepted or rejected based on its measured alloy, can be set relatively large.
  • the prevention of the bouncing or jumping of the coins in the area of the inductive sensors by the newly designed ribs 7 in combination with the described, detailed signal analysis now enables the setting of very narrow tolerance values for the sizes K2 or P2 or H2 or I2.
  • FIG. 6 shows an advantageous electronic circuit 14 with a series resonance circuit RLC for the separate detection of the change in the ohmic resistance R S and the inductance L S of a coil S.
  • Series resonance circuit RLC represents a purely ohmic impedance Z S in the case of resonance, which is equal to the resistance R S of the coil S.
  • a parallel resonance circuit in the resonance case in which the coil S and the capacitive element C are connected in parallel, behaves like an impedance Z.
  • P j C * R S L S , which depends on the ratio of the resistance R S to the inductance L S of the coil S (j denotes the imaginary unit).
  • the electronic circuit 14 has a differential amplifier 18 with an inverting input 19 and a non-inverting input 20, a resistor 21, a two-stage amplifier circuit 22 and an amplitude detector 23.
  • the series resonance circuit RLC consists of the coil S and a capacitive element C, which are connected in series, and is connected to one terminal with ground m and the other terminal to the inverting input 19 of the differential amplifier 18.
  • the output of differential amplifier 18 is fed back via resistor 21 to inverting input 19 and via amplifier circuit 22 to non-inverting input 20.
  • the amplifier circuit 22 has the tasks, first to make the series resonance circuit RLC vibrate when the circuit 14 is switched on and secondly to provide an amplitude-stabilized voltage U 3 (t) for excitation of the series resonance circuit RLC.
  • This object is achieved by two inverters 24 and 25 connected in series and a voltage divider 26 connected in series.
  • a capacitor 27 and 28 is connected upstream of the input of the inverters 24 and 25 and the output of the inverters 24 and 25 is connected via a resistor 29 and 30 fed back to the input.
  • the capacitors 27 and 28 are used for DC decoupling.
  • the resistors 29 and 30 determine the DC operating point of the inverters 24 and 25, respectively.
  • the amplifier circuit 22 behaves like a linear AC amplifier, so that because of the positive feedback of the output voltage U 1 (t) of the differential amplifier 18 on its input 20 the series resonance circuit RLC begins to oscillate.
  • the gain of the input signal U 1 (t) is chosen so high that the second inverter 25 is then always saturated, so that a rectangular voltage U 2 (t) is present at its output, the two voltage levels of which are the positive and the negative voltage levels correspond with which the entire electronic circuit 14 is fed in a manner known per se with respect to the mass m bipolar. With the help of the ohmic, against mass m leading voltage divider 26, the level of the voltage U2 (t) is reduced.
  • the voltage divider 26 has two resistors 31 and 32, the resistor 31 being of the order of magnitude of the resistance R S of the coil S.
  • the resistor 32 is dimensioned so that the level of the voltage U3 (t) is a few tens to one hundred millivolts.
  • the amplitude detector 23 is used to measure the amplitude of the voltage U 1 (t) and the transmission to the microprocessor 15 in a suitable form.
  • the resonance frequency ⁇ 0 (L S ) changes with the change in the inductance L S.
  • the circuit 14 described operates in such a way that the series resonance circuit RLC oscillates at a frequency ⁇ which is always equal to the resonance frequency ⁇ 0 (L S ).
  • the coin M passes the coil S, its resistance R S also changes .
  • the evaluation of the signal U1 (t) is now carried out by the microprocessor 15 as previously described.
  • the frequency ⁇ of the square wave voltage U2 (t) present at the output of the second inverter 25 can be determined in a simple manner, not shown, for example with a counting module which can be released for counting by the microprocessor 15 in accordance with the time course of the amplitude of the voltage U1 (t) while the coin M covers the coil S.
  • the so determined in the coil 9 or in the coil 10 frequencies ⁇ 1 or ⁇ 2 correspond to the resonance frequencies when passing the coin M and represent a third and fourth characteristic size K3 or K4, which as further decision criteria for the acceptance or rejection of the coin M can serve.
  • the sizes K1 and K2 and thus the alloy composition and the thickness d of the coin M can be determined with an accuracy which is sufficient to distinguish a large number of coins M.
  • a coin M2 of a certain alloy and greater thickness d can be simulated with a coin M1 of small thickness d or with a thin metallic plate by deliberately increasing the distance of the coin M1 or the metallic plate from the coil 9 is, for example by inserting a non-metallic layer between the coin M1 and the coil 9, it is sufficient to determine whether the resonance frequency ⁇ 0 (L2) of the coil 9 during the passage of the coin M is greater or less than in the absence of a coin.
  • the sign of the change in resonance frequency ⁇ 0 (L2) of the coil 9 thus advantageously serves as a further decision criterion for the acceptance or rejection of the coin M.
  • An exact determination of the resonance frequency ⁇ 0 (L2) in the presence of the coin M is not necessary.
  • the arrangement of the coil 9 or 10 in the series resonance circuit RLC offers the advantage that a quantity characterizing the alloy composition or the thickness d characterizing quantity can be determined with a simply constructed circuit which measures the damping of the series resonance circuit RLC in the presence of the coin M.
  • the series resonance circuit RLC therefore represents a particularly suitable means for measuring the change in resistance induced in the coil S. This also makes it possible to identify coins which, when using a parallel resonance circuit, result in no or an inadequate signal change if the changes in the inductance L S and the resistance R S compensate one another.
  • the inductance L S of the coil S and the value of the capacitive element C are selected such that the resonance frequency ⁇ 0 (L S ) of the resonant circuit RLC is in the range from 50 to 200 kHz, a typical value being 90 kHz. At these frequencies, the depth of penetration of the magnetic field generated by the coil S into the coin M is sufficiently large that the material composition of the coin M can be determined sufficiently selectively.
  • Inverters 24 and 25 can be, for example, inverters of the known type 4007.
  • at least one of the inverters 24 or 25 is replaced by a NAND or a NOR module with an additional input, the additional input being connected to an output of the microprocessor 15.
  • the circuit 14 can be switched on and off in a simple manner via the logic potential at this output of the microprocessor 15. The circuit 14 can therefore only be switched on for a short time just for checking a coin M.
  • the replacement of both inverters 24 and 25 by a NAND or a NOR module offers the advantage that the circuit 14 requires very little energy when switched off.
  • FIG. 6 shows only one example of an electronic circuit 14 which is suitable for detecting the change in the resistance R S of the coil S by means of a series resonance circuit RLC.
  • a series resonance circuit RLC In the technical literature there are countless other examples of electrical circuits of the series resonance circuit RLC which excite the series resonance circuit RLC with a voltage or a current.
