Definitions

the invention relates to a coin testing device according to the preamble of claim 1.
Soil probes are particularly advantageous for so-called Bicolour coins made from a core with one around it put around ring. Ring and cores have a different one Color, hence the name mentioned. Also the material chosen for the ring and core is different.
the invention is therefore based on the object of a coin testing device to create that is also able to create bicolour coins better discriminate and the overall the Test security also increased for other coins.
test probes vertically on a common axis so arranged that, for example, the damping curves which generate the measurement signals of both test probes, occur simultaneously.
the test probes which are, for example, inductive probes, can be on a Side of a coin channel arranged and the rolling past Be assigned to the area of the coins.
one of the Test probes point-shaped and the other flat be.
one of the test probes is also conceivable as an edge test probe by placing it in the bottom of the Coin runway is sunk. Such a soil test probe is known per se.
the coils are arranged so that mutual overcoupling is avoided becomes.
the parallel processing of the sensor signals is possible because the coin run past the probes takes significantly longer than the analog-digital conversion a measurement signal. For example, the coin run on the Probes past 50 ms while the analog to digital conversion of a Measurement signal in the order of 10 microseconds takes place. Because of this time ratio results when the evaluation is ongoing at least of two signal curves occurring at the same time a variety of evaluation criteria, for example Differential and partial areas, intersections and combinations from these events. Because of the acceleration of probes arranged exactly one above the other can also the slopes at certain points on the signal curves be used for evaluation.
the coin validation device has a number of benefits. So due to the arrangement of the probes Intersection points are generated automatically and for example the distance of the intersection points from the symmetrical Timeline can be determined, which is a statement of authenticity of the tested coin. Furthermore, difference areas or individual partial areas are examined, also in Connection with programmable offsets. Especially at As already mentioned, bicolour coins arise above all with surface probes, small differences in damping between Ring and core material. Accordingly, you only have smaller ones Slumps in the rise and fall of the coin curve can be expected. These slope changes can usually be made difficult to evaluate. When using a second on the same Axis arranged test probe, for example only the When viewed in a ring, there is a multitude with the first curve of combinations of evaluation criteria.
a coin track 10 is indicated, which is usually is attached to a raceway support plate 12 (Fig. 2). Between the raceway support plate 12 and a main plate 14 a coin channel 16 is formed, with on the Coin runway 10 Roll coins along in coin channel 16. In 1 and 2, a coin is marked with 18.
inductive test probes 20, 22, 24 In the main plate 14 there are three inductive test probes 20, 22, 24 arranged one above the other. Your measuring axes lie on one Axis 26, which is perpendicular to the plane of the coin track 10 stands. Another test probe 28 is in the coin track 10 arranged. Your measuring axis coincides with axis 26.
the test probes 20 to 24 are so-called area probes "view" part of the area of the coins 18, with the Example the probes 20, 24 the ring 30 of the bicolour coin 28 and probe 22 "looks" at core 32. Probes 20 to 28 are inductive probes. The test probe 28 is used for the examination the edge of the coin 18th
the signal curve 40 is, for example, the sensor 28 shown for example for a coin with a value of 1 euro.
a curve 42 shows the signal profile of a test probe, as represented by one of the probes 20 to 24. It can be seen that the curves 40, 42 are largely symmetrical are to the time axis 44. The overlap of the curves 40, 42 results thus, for example, two partial areas 46, 48, their difference for example for authenticity checks can. Furthermore, there are s1, s2 above intersection points an area 50, which is also used for the authenticity check can be. The position of the intersections s1, s2 can also be used for the authenticity check can be used, for example by measuring the distance to the axis of symmetry 44.
a further curve 42 ' is indicated by dash-dotted lines, to show that there can be curve shapes, in which due to the high slope of the measurement curve 40 Intersection s1 and s1 'of curve 40 with curves 42 and 42 'may have relevant amplitude differences U1, U2, while the measured values S1, S1 'are close in time, i.e. form a ⁇ U that cannot be evaluated.
the curve 5 is that of a floor sensor, corresponding to the sensor 28, generated signal curve designated 52 and that for one Area sensor with 54.
the curve 52 corresponds approximately to that Course of curve 40 according to FIG. 1 and is characteristic for the formation of the edge of a bicoloured mune.
the curve 54 is obtained, for example, from a sensor such as it is designated 22 in Figs. 1 and 2, i.e., when painting of coin surface sections both in the core 32 and also in edge 30 of coin 18.
intersection points s3 and s4 for the coin check can be used.
a third curve 52 ' is indicated in FIG curve 54 intersects at s3 '.
the reverse Fall as in curve 42 ' i.e. the amplitude values U1 and U2 have a negligible difference, while the temporal position, expressed by T1 and T2 clearly is different.
58 again designates one Curve by a soil sensor, corresponding to soil sensor 28, is generated.
curve 60 stems from one Sensor forth, as it is designated in Fig. 1 with 20 or 24, i.e. only one material is also measured.
the overlapped areas can be used for evaluation or alternatively the slopes, approximately on both sides of the symmetry time axis 44 ′′ have to be the same.
FIG 3 is a first sensor by a probe 70 in the main plate 14a and a second Sensor formed by probes 72, 72 'in the raceway support plate 12a are arranged.
the probes 70, 72 are coaxial, but have a different diameter.
Such a pair of sensors also generates signal curves at the same time when passing coins, that described in the above Be used to form authenticity criteria can.
