Definitions
- the invention relates to a device for coin testing, with at least one self-induction coil excited with high frequency and serving as an inductive probe, which can be influenced by the coin to be tested to generate a signal dependent on the type of coin.
- the embossing pattern for example, specifying a number and the currency on one side and the 'Playing a mint design, such as a coat of arms, on the other side of the coin. Coins of approximately the same dimensions and alloy differ only in the minting pattern. In the case of known devices for checking coins, however, the embossing pattern is disregarded.
- the invention seeks to remedy this.
- the invention as characterized in claim 1, solves the problem of creating a device for coin testing which emits a coincidence signal if the minting pattern of the coin to be tested matches the minting pattern of one of several, specific, to be accepted coins .
- Particular embodiments of this invention are specified in the dependent patent claims.
- the advantages achieved by the invention are essentially to be seen in the fact that the embossing pattern on one side of the coin is generally sufficient to distinguish the coin from coins of all other types and, if appropriate, to assign them to a specific one of several types of coin provided as acceptable. Since several types of coins of the same currency are often the same Having a coin picture in different sizes, it is essential that the device according to the invention also distinguishes such coins. Further advantages of the invention and its embodiments are apparent from the following description.
- 1 and 2 is a side view and a section through a coin guide
- 5 is an overview circuit diagram of a device for coin testing
- Fig. 6 is a signal diagram.
- the coin guide of which FIG. 1 shows a side view and FIG. 2 shows a cross section along the line II-II in FIG. 1, has a runway surface 1 for the coin 2 to be tested and a steep guide surface 3, on which the runway surface 1 rolling coin 2 with its front or back side slides.
- an inductive probe 5 which extends up to or almost up to the guide surface 3.
- the diameter of the probe 5 is substantially smaller than the diameter of the smallest acceptable coin, and the distance of the probe 5 from the runway surface 1 is larger than the radius and smaller than the diameter of the coins to be accepted that has the smallest diameter. It is thereby achieved that the probe 5 scans a track of coins of the intended diameter range rolling past it that is sufficiently long for the present purposes described in more detail below.
- Fig. 3 shows the coin 2 with a scanning track
- Fig. 4 shows three phases of the scanning process.
- the coin reaches the probe 5 in its position 2a, whereupon the point 7 of the coin edge passes the probe 5.
- the coin 2 is in a middle
- Probe 5 passes. 10 denotes the track which is scanned by the probe 5 in this process.
- Position 2b is scanned half 10a of track 10.
- the location of the track 10 relative to the pattern of the embossing is indefinite because it is uncertain as to the locations 7, 8 and 9 with respect to that
- Embossing patterns lie. If, for example, the coin reaches the probe 5 in a position which is offset by 90 angular degrees in a clockwise direction relative to the one shown, the track designated 11 is formed. It can also be seen that two coins of different diameters are the same
- the oscillating circuit voltage decreases due to the influence on the damping when the point 7 of the (not recessed) coin edge of the coin 2 passes the probe 5.
- the oscillating circuit voltage then fluctuates in accordance with the changes in the embossing depth along the scanned track, and finally the oscillating circuit voltage rises again when the point 9 of the coin edge passes the probe 5.
- Such a course of the resonant circuit voltage is shown in FIG. 6. The frequency of the oscillator vibrations changes accordingly.
- signals of this type obtained on different tracks on both sides of each type of coin to be accepted are stored in a memory (33, FIG. 5).
- an acceptable coin is released from a part of the runway surface (not shown) with a gradient in different starting positions, in order to roll past the probe 5.
- the different starting positions are obtained either by placing the coin in the same place but at the same angle Rotational positions offset against each other or in each case in the same position at points on the runway that are offset along the same by a fraction of the coin circumference.
- analog signals are obtained for each coin to be accepted on tracks evenly distributed over the embossing pattern.
- the diameter of the area of its alternating magnetic field in which its self-induction or damping can be most strongly influenced corresponds to a width of the scanning track, in which adjacent tracks essentially adjoin one another.
- the signal obtained with a coin to be checked is compared with each of the stored signals and, if there is sufficient agreement, a match signal is emitted.
- the probe 5 forms the resonant circuit coil of an oscillator 13. Its output voltage is demodulated in a demodulator 18, as a result of which the analog signal 14 shown in FIG. 6 is obtained.
- a scanner 20 controlled by a time pulse generator 19 supplies signals 21 which correspond to discrete values of the analog signal 14 which follow one another at a distance of, for example, 1 ms. 6 shows only some of these signals 21. In this case, for example, 50 signals 21 are obtained from the signal 14.
- the signals 21 are further processed and compared with the stored signals using the digital method. Accordingly, an analog-to-digital converter 23 follows the scanner 20.
- the digital method is carried out in practice by means of a microprocessor, which is indicated in FIG. 5 by a dash-dotted frame 25.
- some assemblies that are essential for the mode of operation are shown in simplified form in this frame 25.
- sequences of signals of discrete values can only be compared with one another if each sequence contains the same number of signals, an always the same number Z of signals which are essentially uniformly distributed over this signal sequence is selected from the signal sequence 21.
- the signals 21 are transmitted to a first shift register 27 and at the same time to a counter 28.
- a divider 29 divides the number Z of the signals 21 by the desired number z of the signals to be selected.
- the selection principle then consists in that a selection circuit 31 transmits the first (or last) of n successive signals 21 into a second shift register 32, where n is equal to Z by z.
- n is usually not an integer.
- n is rounded down to the next, smaller, whole number and the selection circuit 31 with the rounded number controlled. Although the desired number of signals is selected, a last part of the signal sequence 21 is not taken into account.
- the integer multiples of the quotient n are rounded off or rounded up to an integer, and those of the signals 21 are selected whose position in the signal sequence corresponds to the rounded up or down numbers. For example, if n is 3.3, the integer multiples are 3.3, 6.6, 9.9, 13.2, ..., and the third, seventh, tenth, thirteenth, ... of the signals 21 is selected, that is, from the first shift register 27 in transmit the second shift register 32.
- the signal sequence stored in the second shift register 32 is compared in a comparator with each of the signal sequences stored in the memory 33 and with the coin types to be accepted, in each case by the first, second, ..., zth signal of the signals in the second shift register 32 stored signal sequence with the first, second, ... z-th signal of the signal sequence to be compared in the memory 33 and the difference is formed in a subtraction unit 34.
- An adder 36 adds the absolute values of the differences.
- a comparator 38 outputs a match signal on a line 39 when the sum obtained from the adder 36 falls below a predetermined value.
- two probes which follow one another in the direction of the coin movement can be arranged at equal distances from the runway surface 1 (FIGS. 1 and 2). ordered, the test signal from each of the two probes is compared with the signals stored in the memory and a match signal is generated if the comparison of one of the two test signals shows a match within the given limits.
- the two test signals (if the distance between the probes in the direction of the coins is small) can be sampled alternately (as in the time-division multiplex method) and the discrete values of one test signal can be stored in one and the other in another of two shift registers, which replace the shift register 27.
- the influence of the probe depends not only on the distance of the probe from the point of the coin surface in front of it, but also on the property of the coin alloy. For this reason, coins with the same diameter and the same minting pattern only give a match signal if the alloys also match within the given limits. Since - as mentioned - coins of different diameters, which have the same minting pattern in a correspondingly different size, are distinguished from one another by the test described, this test is sufficient in principle to distinguish coins that are to be accepted from those that are not. Because of its complexity, the test of the embossing pattern is preferably applied to coins of higher values.
- the present device in a coin validator, in which the diameter, thickness and alloying properties of the coins are checked in the usual way, and to switch on the checking of the minting pattern only if these usual checks show that it can be a coin of higher value to be accepted.
- the signal processing in all tests can be carried out with one and the same microprocessor. If the test of the embossing pattern is only used for coins of higher values, a smaller capacity of the memory 33 is sufficient, or, which may be more important, it is possible, for a given storage capacity, to store more discrete values of a larger number of tracks for each of the few coins of higher values and gains greater resolution in pattern scanning.
