Definitions

  • the invention relates to a device for checking coins, which contains a measuring and an evaluation device.
  • a testing and sorting device for coins in which the impedance of a winding which is exposed to an alternating current with a suitable frequency changes as soon as a coin is introduced into the inside of the winding .
  • the impedance forms a branch of an alternating current Wheatstone measuring bridge, and the device contains a control system with which the instant or the position of the coin is determined in which or in which the coin check takes place.
  • a reference impedance is used, which consists of a further winding in which a valid coin of known value is arranged in a certain spatial position.
  • the decisive factor for the coin check is therefore the overall effect of the coin on a winding impedance during a short period of the coin movement or when the coin occupies a certain spatial position.
  • a coin testing device in which the coin to be tested rolls down a ramp past three electromagnetic measuring heads, the electrically measured coil inductance values of which are affected by the rolling coins.
  • a measuring head is larger than the largest coin to be checked.
  • the measured inductance values depend on the coin diameter and the surface condition of the coin.
  • An inductance coil is part of an oscillating circuit which oscillates at a frequency of 1 MHz without a coin. The coin influences this oscillation frequency, and the peak frequency caused by it is compared with predetermined, statistically determined limit values.
  • the invention has for its object to refine the measurement methods mentioned and to find a device that determines the authenticity and value of a coin even if the difference between the coin to be tested and another known real coin of a given value or a very good one Counterfeit coin is extremely low.
  • the device should also be able to control the dimensions and the spatial position of a metal thread in a banknote.
  • the length L of the measuring head 3 is z. B. at least twice the width of this measuring head 3.
  • This consists of a cylindrical tube 4 slit parallel to the longitudinal axis made of magnetic material, on which a measuring head coil 5 is wound in the longitudinal direction.
  • the longitudinal axis of the tube 4 and the rolling surface 2 of the coin 1 are arranged parallel to one another.
  • the measuring head coil 5 is arranged on the tube 4 in such a way that the magnetic flux ⁇ generated by it within the tube 4 is perpendicular to its longitudinal axis and circular within a tube cross section, for example counterclockwise the pipe center flows.
  • the lines of magnetic flux of the magnetic flux ⁇ close over the slot of the tube 4 serving as the air gap 6 and are shown in broken lines in FIG. 1b.
  • the distance of the center line of the air gap 6 to the rolling surface 2 can have any value between zero and the coin diameter D.
  • the rolling surface 2 and a sliding plane 7 arranged perpendicular to it and parallel to the longitudinal direction of the tube 4 and carrying the measuring head 3 are preferably made of non-metallic material.
  • the coin 1 rolls on the rolling surface 2 along the air gap 6 of the tube 4. Simultaneously and due to the angle of inclination a of the sliding plane 7 with the vertical AB, the dead weight of the coin 1, possibly reinforced by the pressure of a brush not shown, presses the coin 1 against the sliding plane 7, so that the coin 1, in addition to its rolling movement on the rolling surface 2, this sliding plane 7 slides along.
  • the sliding plane 7 is arranged tangentially to the cylindrical tube 4 along the center line of the air gap 6.
  • the dimensions of the e.g. B. rectangular air gap 6 are as constant as possible over the entire length of the tube 4. As shown in FIG. 1c, the air gap 6 can also be designed differently depending on the desired resolution of the surface scanning of the coin 1.
  • a metal plate 8 made of magnetic or non-magnetic material can be arranged in the air gap 6 flush with its outer surface, namely parallel to its longitudinal edges and perpendicular to the magnetic flux ⁇ .
  • the outer surface of the cylindrical tube 4 can be lined with a metal surface 9 made of magnetic or non-magnetic material in the vicinity and on both sides of the air gap 6, but not entirely up to its edges, if necessary in addition to the metal plate 8.
  • the air gap 6 can also be one have a trapezoidal cross-section that widens towards the inside of the pipe. 1c, the measuring head coil 5 has not been shown for reasons of clarity.
  • the length L of the measuring head 3 is less than or equal to the sum of a coin size ⁇ D and a coin diameter D, i.e. ⁇ ( ⁇ + 1) - D selected.
  • the distance between the center line of the measuring head 3 or the air gap 6 and the coin center is to be selected so that as many characteristic features of the coin surface as possible are checked and evaluated.
  • the measuring head coil 5 is, as can be seen from FIG. 2, with an alternating current of a suitable frequency, for. B. 50 kHz, fed.
  • a suitable frequency for. B. 50 kHz
  • the magnetic flux ⁇ in the vicinity of the air gap 6 is determined by the characteristics of the coin 1, e.g. influenced by its surface quality as soon as it moves in the area of the air gap 6.
  • the magnetic flux ⁇ generated in the coin 1 by the alternating current exclusively causes eddy currents, the effect of which on the measuring head coil 5 in turn influences its inductance value.
  • rolling coins of both types has the consequence that the inductance value and the equivalent loss resistance value of the measuring head coil 5, and thus also the constant voltage supply, the electrical voltage across this measuring head coil 5 as a function of the coin characteristics and in particular as a function of the coin surface characteristics, such as B. the embossed image, continuously changes while rolling past.
  • the measuring devices shown in FIG. 2 each consist of the measuring head 3, a signal converter 10, an AC voltage generator 11 and a demodulator 12.
  • the measuring head 3 and the signal converter 10 shown in FIG. 2a form a measuring bridge, in one branch of which the measuring head coil 5 of the measuring head 3 is arranged.
  • a first pole of the measuring head coil 5, a first bridge coil 13 of the signal converter 10 and the AC voltage generator 11 are connected to one another.
  • the second pole of the measuring head coil 5 is located at the input of the demodulator 12 and at a first pole of a series circuit 14 of the signal converter 10, consisting of an adjustable second bridge coil 15 and an adjustable resistor 16.
  • the respective second pole of the AC voltage generator 11, the first bridge coil 13 and the series circuit 14 are interconnected.
  • a center tap of the first bridge coil 13 is connected to ground.
  • the output of the demodulator 12 forms the output of the measuring device.
  • the signal converter 10 of FIG. 2b consists of a single capacitor 17, which together with the measuring head coil 5 results in a series resonant circuit which is fed by the alternating voltage generator 11.
  • the common pole of the measuring head coil 5 and the capacitor 17 is connected to the input of the demodulator 12, while the other pole of the measuring head coil 5 and with it a pole of the AC voltage generator 11 is connected to ground.
  • the output of the demodulator 12 is equal to the output of the measuring device.
  • Both circuits of FIG. 2 have in common that the electrical voltage across the measuring head coil 5 has the same frequency as the current generated by the alternating voltage generator 11 and its amplitude through the variations in the inductance value and the equivalent loss resistance value of the measuring head coil 5 and thus through the characteristics of the coin 1 is modulated.
  • This amplitude-modulated voltage is demodulated in demodulator 12, so that an analog voltage corresponding to these characteristics appears at its output.
  • the block diagram of a test device shown in FIG. 3 contains, in addition to a measuring device already shown in FIG. 2, an evaluation device 20 including the signal converter 10 and the demodulator 12.
  • the output of the demodulator 12 feeds the input of a sample / hold circuit 21 of the evaluation device 20.
  • This also contains an analog / digital converter 22, a measured value memory 23, a reference value memory 24, in which the characteristic of a reference coin is stored, a cross correlator 25, a pulse shaper 26, a time control element 27, an AND gate 28 with m inputs and an electromagnetic switch 29.
  • the analog / digital converter 22 is only required for a digital variant if the two memories 23 and 24 are digital memories, otherwise it can be omitted.
  • the AND gate 28 is designed for m measuring heads 3.
  • the AND gate 28 can be omitted.
  • the output of the sample / hold circuit 21 feeds the digital variant, the analog input of the analog / digital converter 22, while its digital output is connected to the data input of the measured value memory 23.
  • the output of the sample / hold circuit 21 is connected directly to the data input of the measured value memory 23.
  • the output of this memory feeds a first input of the cross-correlator 25 and the output of the reference value memory 24 feeds a second input of the cross-correlator 25, the output of which is connected to the input of the time control element 27 via the pulse shaper 26.
  • a rectangular clock signal “Clock 1” feeds a second input of the time control element 27.
  • the remaining inputs of the AND gate 28 are connected to the outputs of the time control elements 27, which belong to the other measuring heads.
  • the output of the AND gate 28 is in the case of several measuring heads 3 to the input of the electromagnetic switch 29.
  • the electromagnetic switch 29 switches a coin channel (not shown) from a container for rejected coins to a container for accepted coins.
  • the pulse shaper 26 can e.g. a comparator can be used.
  • This is sampled n times by the sample / hold circuit 21, and the n, analog sample values obtained in this way are stored either in the analog variant directly in the then analog measured value memory 23 or in the digital variant after conversion of the analog values into digital values With the aid of the analog / digital converter 22, it is stored in the then digital measured value memory 23.
  • the corresponding analog or digital reference values of a valid coin of known value are stored in the reference value memory 24.
  • the measured values and the reference values are now called up successively and synchronously from the associated memories, the call is repeated periodically with the same period for all measured values or reference values, and the values thus called are fed to the two inputs of the cross-correlator 25 and in them measured values and associated ones Reference values compared with each other.
  • the measured values and the reference values each represent a periodic characteristic of the period T as a function of time.
  • the use of a cross-correlator 25 is also necessary, among other things, because the initial position of the coin 1 with respect to its surface structure when entering the measuring section is arbitrary, not always the same and in the rarest cases is identical to that of the reference coin at the time when the storage of its reference values began.
  • the cross-correlator 25 determines the mathematical short-term cross-correlation function where m (t) the time function of the measured values, r (t- ⁇ ) the time function of the reference values and i an independent variable which contains the delay time caused by the different coin starting positions. If there is a correlation between the reference coin and the coin 1 to be checked, the output signal of the cross-correlator 25 consists of periodic, more or less bell-shaped pulses (FIG. 4f).
  • the pulse shaper 26 If, on the other hand, there is no correlation, either these impulses are missing or their amplitude is significantly weaker. If the pulse amplitude exceeds a certain value S (FIG. 4f), the pulse shaper 26 generates an ideally rectangular pulse for the duration of the exceeding. However, these pulses only appear at the output of the time control element 27 if their time interval is correct, ie if they occur with the period T. The control is done with the help of the rectangular clock signal "Clock 1". These pulses, which are thus typical of a “good” signal, control the electromagnetic switch 29, which switches the coin channel from the container for invalid coins to the container for valid coins.
  • an analyzer can also be used, which, with the aid of e.g. B. a Fourier analysis, special characteristics of the time functions of the measured values and the reference values are determined and compared with one another.
  • measuring heads 3 are used e.g. a number m, each of them requires its own measuring and evaluation device, with the exception of the electromagnetic switch 29, which is common to all measuring heads 3 and is controlled by the outputs of the m time control elements 27 via the AND gate 28. All m measuring heads 3 are e.g. arranged spatially parallel to the rolling surface 2 and all of their air gaps 6 have e.g. a different distance from the coin center. The measuring heads can also be arranged on both sides of the coin channel for checking both coin surfaces. A practical value for m would be e.g. the value 3 for each coin surface.
  • each electromagnetic measuring head is arranged perpendicular to the direction of movement EF of the coin 1 and the length L of these measuring heads is chosen to be less than or equal to the largest coin diameter D.
  • the coin 1 to be checked rolls or slides past each of the measuring heads.
  • the arrangement advantageously consists of a first measuring head 3 and a second measuring head 3a.
  • the two measuring heads 3 and 3a are arranged in parallel in such a way that their two air gaps 6 and 6a face each other on both sides of the coin channel and the coin 1 between the two measuring heads 3 and 3a closely moves or rolls past both air gaps 6 and 6a.
  • This combination of measuring heads is advantageously located directly behind the coin insertion slot C of a coin machine. It also allows an at least approximate diameter measurement when inserting coins of different sizes.
  • the cylindrical tube 4 has been replaced by an elongated plate made of magnetic material, on which the measuring head coil 5 is wound in the longitudinal direction and perpendicular to the surface.
  • the coin 1 rolls e.g. along one of the longitudinal narrow sides 30 of the plate, on which a Hall element 31 of approximately the same length is fastened.
  • the longitudinal center line of the longitudinal narrow side 30 forms the center line of the measuring head 3.
  • the direction of movement of the coin 1 can be perpendicular to the center line of the measuring head 3.
  • the movement can be rolling or sliding.
  • the electromagnetic measuring heads 3 described so far can also be replaced by the optical measuring heads 3 shown in FIG. 7.
  • Each of these optical measuring heads 3 consists of a row of k light guides, preferably of the same cross-section, all of which consist of fiber bundles or individual fibers, one end 32 of which the coin 1 rolls or slides across the light guide direction and the center of which is the center line of the measuring head Form 3, all are arranged flush and parallel in one plane.
  • the other ends of the light guides lie alternately at the output of an optical transmitter 33 or at the input of an optical receiver 34.
  • the number k of light guides and their cross section is to be selected such that the length L of the light guide row is equal to the measuring head lengths indicated for FIG. 1.
  • the number of optical transmitters 33 is approximately equal to the number of optical receivers 34.
  • the light beam transmitted by the optical transmitter 33 is reflected by the rolling or sliding coin 1, its amplitude is modulated as a function of the surface structure of the coin 1 and is fed to the associated optical receiver 34 via the adjacent light guide.
  • the amplitude-modulated optical signal is converted into an amplitude-modulated electrical signal using known converters. As described for FIG. 3, this can then be processed with the aid of a demodulator 12 and evaluated in an evaluation device 20.
  • planar layered waveguides can also be used, such as those e.g. in the journal Naturwissenschaften 67, 1980, on pages 347 to 351.
  • the invention can also be used to check the position and dimensions of the metal thread in banknotes.
  • a suitable means of transport e.g. a conveyor belt is provided for transporting the banknotes along the measuring heads 3.
  • the banknote is advantageously moved perpendicular to the direction of the metal thread and the longitudinal axis of the measuring head 3 is arranged parallel to this metal thread.
  • multiple measuring heads e.g. their longitudinal axes are aligned in a line.
