Definitions

  • the present invention relates to a procedure and device for the identification of metallic discs, such as coins or tokens, and is particularly applicable to de identification of coins consisting of two or more parts of a different nature, for example coins with a crown and the nucleus made from metal or different alloys, or multilayer coins.
  • the invention also includes the device which carries out the procedure.
  • the invention relates to a procedure and device providing precise information on the size of the coin and the nature of the different parts of which it consists, in order to correctly identify it, all of this by the features of the independent claims. Preferred embodiments are defined in the dependent claims.
  • the invention is applicable for the differentiation of monometallic coins providing great certainty in rejection of frauds consisting of adding to a coin of lower value a ring of different material, such as plastic tape, aluminium, rings of different alloys, etc., in order to simulate a higher value coin.
  • a sensor of the same type is also described in U.S. patent 4754862, in which a coin discriminating device is proposed incorporating three electromagnetic sensors, each consisting of a single coil and arranged so that the coin interferes with them sequentially.
  • the sensors share a single oscillator, but in this case a multiplexor is used to activate each sensor as the coin passes.
  • the size of the sensors, two at least, is similar or greater than that of the coins to be analysed.
  • Patent PE.0076617A2 proposes a measurement procedure applicable to two-coloured coins based on using small Hall effect sensors. With these sensors the variations of the magnetic field caused by the coin under analysis can be measured with an acceptable spatial precision.
  • the object of the present invention is to solve the aforementioned problems by a procedure and device which allow a precise measurement of the properties of the alloys of their different parts, all of this without requiring expensive electronic components nor miniaturised electromagnetic sensors.
  • the invention proposes a procedure for the identification of metallic discs, particularly coins consisting of a crown and a nucleus of different natures, according to the independent method claim: a) obtention and measurement of the peak of the signal produced when the crown of the coin passes a first electromagnetic sensor, which represents a first characteristic of said crown; b) measurements of the signal level produced as the nucleus of the coin passes a second electromagnetic sensor, at the same time as the peak of the aforementioned signal is detected, which represents a first characteristic of the nucleus of the coin; c) detection and measurement of one of the secondary peaks of the signal obtained as the crown of the coin passes the former sensor, which provides a second characteristic of the crown.
  • the procedure preferrably includes a measurement of the signal level produced when the crown of the coin passes a third electromagnetic sensor at a time between the moment the crown begins to intercept this third electromagnetic sensor and the time it ceases to, which provides a third characteristic of the crown.
  • the procedure includes a measurement of the peak of the signal produced as the nucleus of the coin passes the third electromagnetic sensor, which represents a second characteristic of said nucleus.
  • the procedure of the invention can be completed by obtaining the times in which the coin passes a first and second optical sensor, in order to calculate the size of the coin.
  • the time of the measurement of the signal level produced as the crown of the coin passes the third sensor can be defined by an amount of time after the coin has finished passing the firs optical sensor, which would be located before the third electromagnetic sensor.
  • the second and third electromagnetic sensors can be self-oscillating which allows measurement the frequencies to obtain an additional parameter related to each of the electrical amplitude measurements provided by these sensors.
  • the device for the execution of the described process includes the features of the independent device claim first and second electromagnetic sensors are aligned perpendicularly to the path of the coins and the third electromagnetic sensor at a distance from the aforementioned second sensor along the coin path and placed at the same position as it along the path. Of the two aforementioned electromagnetic sensors, one is placed so that it intercepts only the coin crown, while the other is placed so that it sequentially intercepts both the nucleus and the crown. The third sensor will also intercept sequentially the nucleus and crown of the coins.
  • the device also includes two optical sensors located at the same height along the coin path, separated from each other a certain distance along the coin path and preferably placed at either side of the second electromagnetic sensor mentioned above.
  • the sensors may be made from coupled pairs of inductors, placed on the opposite sides of the coin chute, each inductor pair forming an oscillator so that the different electromagnetic sensors are completely independent from each other, thus permitting measuring of different coin characteristics, particularly of the nucleus, which allows discriminating nuclei consisting of superimposed layers of different metals.
  • the optical sensors provide time signals of the coin passing for calculation of their size.
  • the first electromagnetic sensor is placed on the chute, so that the flux created by this sensor partially intercepts the coin, but fundamentally at its crown. This is important in order to avoid the contact resistance between the crown and the nucleus of the coin, which is uncontrollable, from affecting the quality of the measurement.
  • This sensor can also be built from two coupled coils placed on either side of the coin chute, centred on the rolling channel, so that the coin intercepts approximately 50% of the sensor's diameter. As will be later exposed, by adequately choosing the operation frequency and the mode of operation (emitter-receiver) an efficient discrimination of the coin crown can be achieved, regardless of the nucleus material.
  • the first electromagnetic sensor (2) instead of being located on the rolling track beneath the second sensor (3) could be mounted above said sensor (3) so hat the coin partially intercepts the magnetic flux created between the two inductors of the sensor.
  • This arrangement would naturally have the limitation that it would only be applicable for discriminating coins in a certain range of diameters and crown sizes.
  • Figure 1 shows a longitudinal section of a segment of the rolling track with the device object of the invention and with a coin at the start of the segment.
  • Figure 2 is a view similar to figure 1, showing the moment when the coin simultaneously intercepts the first two electromagnetic sensors.
  • Figure 3 is a similar view to figures 1 and 2, showing the coin in an intermediate situation, at the time when it begins leave the first optical sensor and begins to intercept the third electromagnetic sensor.
  • Figure 4 shows a block diagram of the circuitry used in the device of the invention.
  • FIGS 5 to 7 are diagrams showing the signals obtained when the coin passes the different sensors.
  • Figures 1 to 3 show a segment of the rolling track, labelled by number 1, along which are placed a first and second electromagnetic sensor, labelled 2 and 3, aligned with each other perpendicularly to rolling track (1), and a third electromagnetic sensor (4) separated from the second sensor (3) along the path of the coins and placed at the same height as it with respect to rolling track (1).
  • Electromagnetic sensor (4) as seen in figures 1 to 3, is placed at the end of the area designed for coin measurement. This is a preferred embodiment, but depending on the physical space and the shape of the device casing, said electromagnetic sensor (4) could be placed at the start of the measurement area, for example, before electromagnetic sensors (2) and 3.
  • Electromagnetic sensor (2) consists of two coupled inductors placed next to the rolling track (1) of the coins.
  • the configuration of this sensor will be of the emitter-receiver type and the sensor will be mounted near the rolling track of the coins, so that the electromagnetic field received by the sensor is affected mainly by the coin crown. This can be achieved using for example a 9mm diameter sensor, placed on the rolling track and displaced outwards so that the coins interfere it in approximately 50% of its size. Since this sensor is along the perpendicular line from the centre of sensor (3) to rolling track (1), when the coin is centred on sensor (3) it will also be centred on sensor (2), figure 2.
  • Electromagnetic sensor (3) will also consist of two coupled inductors placed on opposite sides of the coin pass chute 5. At either side of this electromagnetic sensor there will be two optical sensors 6 and 7 in charge of measuring the coin size (chord).
  • coin (5) has a crown 8 and a nucleus 9.
  • Sensor (3) will be of as size smaller than that of the smallest nucleus of the two-coloured coin which may be analysed and will be placed so that when the coin is centred, the interaction with the electromagnetic field created by sensor (3) will mainly be due to the coin nucleus.
  • sensor two shows two secondary peaks P 3 and P 4 , which do not appear for the other coin.
  • peaks P 3 and P 4 are between the two extreme situations described.
  • This property of sensor (2) appears only for certain sensor configurations, in this case emitter-receiver, and for certain operation frequency band, for which reason it is important to design the sensor properly to use this effect. Therefore, by measuring peak P 1 as well as P 3 or P 4 , (P 3 and P 4 are equivalent as they are symmetrical), an additional parameter of the coin ring is obtained exclusive of this ring, since it is created when the coin begins to interfere with sensor (2).
  • a third electromagnetic sensor (4) sensitive to another property of the alloy.
  • sensor (3) is built with the coils connected in phase
  • sensor (4) would be opposite, or perhaps using a different operation frequency or any other variation which would allow obtaining a second characteristic independent of the one from sensor (3).
  • figure 7 shows a signal of sensor (4) working with the two inductors connected in counterphase, as a two-coloured coin rolls along the measurement area.
  • the measurement to consider would be the maximum variation of the signal P 5 of figure 7, which for this particular sensor appears in its mid area and corresponds to the coin centred with sensor (4).
  • the peak value is easily measurable by any of the presently known procedures.
  • electromagnetic sensor (4) will allow to obtain a third property of the crown by measuring the signal level produced as crown 8 passes sensor (4) in a certain moment, which will lie in the time taken for the coin to begin and end intercepting said electromagnetic sensor (4).
  • sensor (4) can be used in combination with one of the optical sensors to obtain the third characteristic mentioned above of the coin crown, reading the amplitude of the sensor (4) signal at a time T 1 taken from the time the coin is in the position shown in figure 3.
  • the electrical signal produced by the sensor can be seen in figure 7, where the central part of the signal represents a second characteristic of the coin nucleus, while the value of signal V 5 , corresponding to its value at a time T 1 after the end of the rise of optical sensor (6), would be a third characteristic of the coin crown.
  • the value chosen for T 1 would depend on the size of the coins to be discriminated and the existing separation between electromagnetic sensor (4) and optical sensor (6).
  • time T 1 can be calculated for each of the coins entered in the device, as it varies inversely to the speed with which they pass the sensors. In this way measurement by sensor (4) of the ring will be carried out at fixed positions for each of the coin values (coin diameters). The average speed of the coin can be easily found by measuring the time of the entry end of the coin between the two optical sensors.
  • the self-oscillation configuration is used for sensors 3 and 4, that is, their oscillation frequency depends on the inductors used as sensors, this frequency can be measured and be an additional parameter related to the readings of electrical amplitude provided by the described sensors.
  • Frequency measurement for each of sensors 3 and 4 described above can be carried out by any known procedure; in our case an impulse count is used for a known time (fixed or variable) with which the frequency of the oscillator will be the quotient of the number resulting from the count and the time of the count.
  • the block diagram appearing in figure 4 shows a sketch of the elements making up the preferred embodiment of the invention proposed.
  • the sensors have been represented in the order in which they are intercepted by coin (5). In the order followed by the coin as it rolls on inclined ramp (1), it first intercepts optical sensor (6), connected to microprocessor (25) in charge among other things of measuring the passing times of the coins by optical sensors to measure their diameter.
  • Sensor (3) consists of two small inductors preferably of the pot-core type of 9 mm diameter, placed on either side of the coin path, connected in phase, that is the electromagnetic fields are added (mutual induction coefficient M>0), and being part of an oscillator 10, followed by a rectifier 11 and an amplifier and signal conditioner 12, the output of which is connected to multiplexor 23, in charge of commuting the different inputs to an analog-digital converter 24 which provides microprocessor (25) with the digital values equivalent to the analog values of the signals from electromagnetic sensors 3, 4 and (2).
  • microprocessor (25) provides microprocessor (25) with the digital values equivalent to the analog values of the signals from electromagnetic sensors 3, 4 and (2).
  • microprocessor (25) to analyse the frequency of oscillation, which also provides information on the characteristics of the coin.
  • the coin In its path along ramp (1) the coin intercepts sensor (2) of ring (8) or outer part of the coin, consisting of two inductors mounted on either side of the coin passage and placed in the rolling track of the coin, so that the electromagnetic flux created between the inductors is intercepted as the coin passes mainly by its outer part (ring).
  • the inductors must be small, 9mm diameter pot-core type inductors being advisable.
  • the sensor configuration should preferably be emitter-receiver. The emitter is fed by a square-signal generator 13 with a resistance 14 in series of a value substantially higher than that of the sensor (2) itself, the set behaving as a current generator modulated by a square signal.
  • R-C filter 15 in parallel with sensor (2).
  • the signal delivered by the receiver of sensor (2) is entered into a current-voltage converter, at whose output is obtained a square signal of an amplitude proportional to the electromagnetic field transmitted between the emitting coil and the receiving one of sensor (2).
  • the signal is made to pass a band-pass filter 15.
  • the filtered signal is suitably amplified in amplifier 18 and then rectified in stage 19.
  • the output is sent to multiplexor 23 to be analysed by microprocessor (25) and electromagnetic sensor (3).
  • Electromagnetic sensor (4) is built similarly to sensor (3) described above, with the difference that the coils are preferably connected in opposing phase (mutual induction coefficient M ⁇ 0), to thus obtain a new distinguishing characteristic of the coin.
  • This sensor can also be built with pot-core type inductors of 9 mm diameter, mounted at a height above the rolling track identical to that of sensor (3), so that the nucleus of the coin under study is analysed.
  • Sensor (4) is part of an oscillating circuit 20 which oscillates freely. This oscillation is affected by the presence of the coin both in its frequency of oscillation and in the amplitude of these oscillations.
  • the oscillation signal is rectified in block 21 and is amplified and filtered suitably in block 22 before applying it to multiplexor 23 for analysis jointly with other signals by microprocessor (25).
  • microprocessor 25
  • a direct connection has been made from oscillator 20 to microprocessor (25) to analyse the oscillation frequency, which also gives information on the characteristics of the coin.
  • Microprocessor (25) analyses the signals it receives from the electromagnetic and optical sensors and processes them according to a function program which may reside indifferently in an internal memory of the microprocessor or in an external one 26, which also stores the parameters representative of admissible coins. Once the coin is measured and the representative parameters have been calculated for each of the sensors, microprocessor (25) compares these parameters with those characteristic of admissible coins, stored in memory 26. If the coin is accepted it is allowed in through an acceptance trapdoor, not shown, through outlet block 28, controlling by other sensors not shown and by input block 27 that it is correctly admitted, avoiding possible fraud. When the coin is admitted, a code is sent from output block 28 identifying the type of coin. Admission may be restricted by external conditions (inhibitors, commands from the vending machine, etc.) these signals being received in block 27.
