Definitions
- the invention relates to a coin according to claim 1 and a method for checking the coin according to claim 11.
- bi-color coins are used worldwide, which consist of an inner core and an outer ring surrounding the core. Core and outer ring are made of different metallic materials. From DE 10 2010 013 148 it is also known to add an additional material component to the coin in the form of a middle ring.
- the middle ring e.g. made of a polymer or a composite material, is electrically insulating and firmly connected to the outer ring and core.
- the testing of bimetallic coins is mainly carried out by electromagnetic measuring methods. It has been found that, for example, by corrosion, the contact resistance between the core and outer ring leads to a falsification of the measurement results. The falsification effect is stronger, the greater the potential differences for the metals or alloys used.
- the middle ring should consist of a transparent, semitransparent, opalescent and / or color-effects-producing material.
- the width of the middle ring is given with preferably between 0.5mm and 3mm.
- the object of the invention is to provide a coin which can be detected well with the aid of optical arrangements. It is a further object of the present invention to provide a method with which the coins having a central ring can be detected in a simple and effective manner.
- the coin according to claim 1 is characterized in that the central ring for electromagnetic waves of a first wavelength range is permeable and / or less permeable or impermeable to a second wavelength range.
- the number of light barrier signals or even the number of light barrier interruptions can be counted.
- the individual times of the light interruption or light transmissions can be recorded in the form of signal changes or signal durations. From the resulting signal, the presence of the transparent or translucent ring can be detected, and determine from the recorded times the individual widths of the outer ring, the translucent middle ring and the metallic core.
- the material of the middle ring is translucent for the visible wavelength range.
- the material of the middle ring is translucent for the invisible wavelength range.
- the material of the middle ring is translucent to the visible and invisible wavelength range and impermeable to one or certain Wavelength ranges of visible or invisible light, in particular for the IR range.
- the latter embodiment of the invention is particularly preferred. The reason is that in coin validators presence photoelectric sensors normally operate with IR light. If the center ring is made of transparent material but is not transparent to IR light, then the sensor array, which is sensitive to both IR and visible light, will respond differently as a coin moves through the optical array the sensor assembly is irradiated free of obstacles or not without obstacles. On the other hand, it is within the scope of the invention to provide the impermeability of the material for the middle ring also for a visible wavelength range, for example for the red region.
- the material of the middle ring is translucent for the visible wavelength range and impermeable to at least one specific wavelength range of the visible light.
- Another embodiment of the invention provides that the material of the middle ring is translucent for the invisible wave range and permeable to at least one specific wavelength range of the visible light.
- the middle ring on a different reflection factor than the core or the outer ring.
- the reflective properties of the coin surfaces can also be determined with the help of an optical Detecting arrangement, if it is different than that of the outer ring or the core.
- the middle ring may reflect more strongly than the core or outer ring.
- additional optically detectable properties of the central ring can be detected by means of a suitable optical arrangement, for example color pigments, UV stabilizers, fluorescent or holographic particles, etc.
- the method of testing a coin with a central ring of electrically insulating material is based on an optical arrangement through which the coins pass, thereby generating a signal which is evaluated in an evaluation device to produce a true or false signal.
- the coins are irradiated by at least one optical transmitter, and an optical arrangement receives the light reflected from and / or through the central ring, and an evaluation device generates a signal when the coins are moved by the sensor arrangement. If, for example, the material of the middle ring is transparent, light in the visible wavelength range is transmitted through the middle ring and can impinge on the sensor arrangement and generate a corresponding signal there.
- a signal may also be generated when invisible light from the light source or optical sensor passes through the material of the middle ring and impacts the sensor array.
- a light barrier lying transversely to the direction of the coin can be provided, and the evaluation device counts the number of signal changes when passing the coin through the light barrier, while at the same time recording the individual times of the light interruption or light transmission over the signal duration.
- the evaluation device analyzes the signal of the sensor arrangement and generates a real signal when the spectrum of the received light corresponds to the material of the middle ring of a real coin.
- white light is generated by the optical sensor
- electromagnetic waves or light are referred to above and below, they are understood to mean light in the wide range of the visible and invisible spectrum, as far as it can be processed with the conventional and currently available elements and devices without protective measures.
- the sensor arrangement is sensitive to at least one limited wave range. According to another embodiment of the invention, the sensor arrangement is sensitive to a wavelength range of visible light. Alternatively, the sensor arrangement may be sensitive to a wavelength range of invisible light. According to another embodiment of the invention, the sensor arrangement is sensitive to a wavelength range of the visible and a wavelength range of the invisible light.
- the sensor arrangement contains at least one sensor element, for example in the form of a phototransistor.
- two or more sensors may be provided.
- a surface or line sensor for this purpose, for example, on one side of the coin channel a light source is used which emits light of the transmissive and locked wavelength range, eg white light.
- a photosensitive area or line sensor On the opposite side is a photosensitive area or line sensor. This sensor is preferably at least as wide as the width of the middle ring of the coin. As a rule, this ring width will be 1.0mm to 1.5mm.
- the photosensitive sensor arrangement is designed such that it detects the two wavelength ranges, namely those of the transmissive light and also those of the blocked wavelength range, or visible and invisible light. In the idle state, the sensor arrangement detects both wavelength ranges because there is no object between transmitter and receiver. If, on the other hand, the coin with the middle ring rolls past the sensor arrangement, first all wavelengths are blocked by the metallic outer ring. If the special material of the middle ring passes the sensor arrangement, only the blocked wavelength range is absorbed, eg the IR range and not the other wavelengths. This is then an evaluable feature that serves to test or discriminate the coins. If, in the process described, the passage of the core past the sensor arrangement, all wavelengths are again blocked.
- the total irradiated area can be determined in size and the width of the individual components of outer ring and core.
- the mechanical dimensions of the coins are determined by means of the signals of the sensor arrangement, in particular the width of the outer ring, the width of the middle ring, the diameter of the core and the diameter of the coin.
- the simplest optical arrangement for testing tripartite coins can consist of a single light path.
- an optical transmitter e.g. one range with visible wavelengths and the other with wavelengths of the invisible spectral range.
- both optical sensors are activated when they receive the light.
- the middle ring is of a material that is not transparent to the invisible light, only one sensor of the two optical paths will receive light as the middle ring passes through the two optical paths.
- the sensor arrangement can also be provided to make the sensor arrangement simultaneously sensitive to wavelengths in the visible and in the invisible range and to activate the optical sensor successively in order to generate once light in the visible and once light in the invisible range.
- two optical transmitters can be used according to an embodiment of the invention. After all is also conceivable, the optical sensor for a short time successively different, ie sensitive for limited wavelength ranges, switch.
- Fig. 1A shows a plan view of a coin of three materials.
- Fig. 1B shows a section through the illustration of Fig. 1A along the line
- Fig. 2 shows schematically a coin according to FIGS. 1A and 1B at
- Fig. 3 shows the approach of the photocells for different materials of the middle ring of the coins.
- Fig. 4 shows a similar arrangement as Fig. 2 with two light barriers one above the other.
- Fig. 5 shows in section an optical arrangement for carrying out the method according to the invention.
- Fig. 6 shows a similar arrangement as Fig. 2 with a line or
- Fig. 7 shows in section the optical arrangement according to FIG. 6 for
- a three-part coin namely a core 1 of a first metallic material, an outer ring 2 of a second metallic material and a middle ring 3 of an electrically insulating material, for example a polymer.
- the material of the middle ring 3 may be translucent or transparent.
- the thickness of the core 1 is dd and the thickness of the outer ring 2 is dr.
- a coin track 20 is shown rolling along the coin 10.
- a two light barriers LI and L2 are arranged, which have a height h above the coin track 20.
- the light barriers consist for example of at least one optical transmitter and an optical receiver or sensor on different sides of the path of the coin 10.
- the light barrier LI operates with light in the visible wavelength range
- the light barrier 2 operates in the IR wavelength range.
- time is taken with the interruptions of the light barriers. The interruption takes place for the first time with incoming marginal edge of the coin 10 in the light barrier LI and represents the time tO in Fig. 3a. At this moment, both wavelength ranges (permeable and non-transparent) are blocked.
- the transmissive wave area is detected by the optical sensor of the light barrier LI, which is represented by the time tl.
- the times t3, t4 and t5 are determined analogously. From the determined time intervals t0 to t1, t1 to t2, t2 to t3, t3 to t4 and t4 to t5, the individual ring widths or the core diameter and the total coin diameter can be determined.
- Such provisions are known per se as disclosed in DE 27 24 868, EP 0 839 364 and EP 0 694 888.
- the determined individual ring widths can be used as security features.
- the light barrier L2 is positioned at the same distance from the track 20 as the light barrier LI, and the distance LI to L2 is known. From these specifications, the mechanical distances of the coins can be calculated.
- the light barrier L2 is designed for a specific wavelength range, for example infrared light. For this particular wavelength range, no signal changes at tl l and tl2, tl 3 and tl4 are now detected, but only at tl5 when the entire coin 10 has passed the light barrier L2, because the material of the middle ring does not transmit the IR light results from the graph of Fig. 3a below.
- Fig. 3b shows the process when a coin is tested with a material of the middle ring, which is transparent to IR light. It can be seen that the same signal curves are then generated for the light barriers LI and L2. This is thus a good discriminating feature for detecting coins provided with a wrong material for the middle ring.
- Figure 3c shows the waveform for the two light barriers LI and L2 for both a conventional bi-color coin and a middle ring coin where the middle ring material is opaque to both the visible and invisible light.
- Fig. 4 are four light barriers each consisting of an optical transmitter and an optical receiver, which are marked with 11 and 1 ⁇ and 12 and 12 ', arranged one above the other at a distance h or h' of the coin track 20 and in one Distance a to each other.
- a conventional coin of smaller diameter moves through the photoelectric barriers 11 and 12
- a waveform t1 and t2 is generated.
- similar signal curves are additionally generated by the light paths 1 ⁇ and 12 '.
- the light barriers are located at the level of a middle ring according to FIG. 1A or 1B, similar signal curves for 11 and 12 as well as 1 ⁇ and 12 'can again be generated, as described in connection with FIG.
- a main plate 30 and a pivot plate 32 is shown, the latter forms the Münzlaufbahn 20.
- an LED 34 is embedded, which irradiates a coin 10 as it travels along the track 20 on the LED.
- a phototransistor 36 Disposed in the main plate is a phototransistor 36 which cooperates with an optical element 38 which produces a lensing action and is in a recess 42 of the main plate 30 with a small diameter portion 40 and receives the light generated by the LED as far as it either does is not blocked by the coin 10 or is passed by a portion of the coin 10, as is the case in connection with the figures described above.
- a line or area sensor can also be provided in a vertical and / or horizontal arrangement, as shown at 44 and 46 in FIG. 6.
- the line sensor 46 is shown in a horizontal arrangement, from the LED 34 via the Whole width is irradiated and in this way to receive light from the LED 34, which is either not locked by the coin or by this.
