Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to a coin sorting device that determines the appropriateness of an inspection coin based on the degree of influence on an oscillating magnetic field.

(B) Conventional technology Generally, such a coin sorting device brings an inspection coin closer to a sensor that forms an oscillating magnetic field, and captures the degree of influence on the sensor caused by the change in inductance, frequency, phase, induced voltage, etc. It measures the characteristics of coins. And as a conventional coin sorting device, Japanese Patent Publication No.
There is a configuration disclosed in Japanese Patent No. 6200, in which two types of sensors are provided for inspection and for reference, a true coin is placed in advance for reference, and when the inspection coin passes through the sensor for inspection, both The suitability of this coin is determined by comparing the measurement results. Further, as a reference setting, there is also a configuration shown in Japanese Patent Publication No. 48-799, for example, in which a variable resistor or a variable capacitor is used so as to be the same as the electrical condition of the reference coin.

However, recently, as disclosed in Japanese Patent Laid-Open No. 49-95692, due to the downsizing of the device and the ease of setting the standard,
Instead of such reference coins and standard setting parts, set the coin determination data for determining the appropriate coins using the semiconductor memory, and when the coin data by the inspection coins is obtained, both data will match within the allowable range. If there is an inspection coin, a method of determining that the coin is appropriate is being adopted. This allowable range should be increased when discriminating coins with significantly different characteristics, but if the characteristics are very similar depending on the type of coin, or if delicate counterfeit coins are inserted. There is no choice but to set the allowable range narrow. In this case, the frequency, voltage, and temperature of the oscillating magnetic field and the influence of external changes of various electric elements in the sensor circuit as well as the circuit, element, and mechanism so that the relative positional relationship between the inspection coin and the sensor are always constant. Each device must be devised to make the device complicated. Therefore, JP-A-48-
Japanese Patent No. 29499 discloses an apparatus in which a circuit or a mechanism for preventing a change over time is omitted by canceling the influence of the fluctuation by adjusting the fluctuation of the inspection condition from the measured value of the coin. However, the technique according to this publication is premised on that the variation of the measured value due to the change over time always changes at the same rate. However, in this type of coin sorting device, it is known that the measured value changes exponentially with respect to the fluctuation of the measurement condition, and according to the above-mentioned conventional technique, the fluctuation of the measurement condition can be dealt with only within a narrow range. .

Therefore, in Japanese Patent Laid-Open No. 56-110194, the rate of change in the measurement conditions is calculated from the measured value of the sensor during standby, and the value of the rate of change is multiplied by a correction coefficient to obtain the correction value. There is disclosed a coin sorting device configured to sense an inspection coin and output a measured value, and correct the measured value with a correction value to cancel the influence of fluctuation. According to such a conventional technique, by setting the correction coefficient in anticipation of the change in the measured value when the measurement condition changes, it is possible to correct the measured value close to the actual value.

(C) Problems to be Solved by the Invention However, in the conventional methods of coping with changes over time, even if there is a difference in accuracy in the correction calculation method in order to correct the measured value, The corrected measured values are not actual ones, but only predictions. However, since there are many factors that change with time and various factors are intricately entangled with each other depending on the external environment, there is a limit in correcting the measured value with a certain function.

Therefore, the present invention does not correct the measured value, but by setting the coin determination data according to the occasion,
The suitability of the inspection coin is determined based on the actual measurement value. Therefore, the coin determination data is corrected by this measurement value every time a proper measurement value is obtained with a genuine coin, in preparation for the next inspection. Further, when the coin determination data becomes unsuitable, the operator operates the changeover switch and then inserts a genuine coin into the apparatus to correct the coin determination data in the correct direction.

(D) Means for Solving Problems In order to solve the above problems, the coin sorting device according to the present invention has a sensor for detecting coin data by measuring the degree of influence of an inspection coin on the oscillating magnetic field, A memory storing coin determination data having an allowable range of, and determining an inspection coin based on whether the coin data is included in the allowable range of the coin determination data, and If the range of 2 is set and the coin data obtained by the inspection coin is within the second range, the data processing device that corrects the coin determination data based on the coin data, and the switching unit are further provided. And
When the switching means is operated, the data processing device corrects the judgment data even if the coin data obtained by the inserted inspection coin is outside the second allowable range. It's something that you do.

(E) Operation When the coin data of the inspection coin is obtained, the coin data is compared with the coin determination data, and if the coin data is within the allowable range, the inspection coin is determined to be proper.
If the coin data also satisfies the second range, which is narrower than the allowable range, this coin is used as the genuine coin with less wear and dirt and is used for correcting the coin determination data. As a result, the coin determination data is corrected to an appropriate value according to changes over time and changes in drift, etc., in preparation for the next coin inspection. However, if the coin determination data becomes unsuitable for some reason and the coin is inserted by operating the switching means, even if the coin data by this coin is not included in the second range of the current coin determination data, The coin determination data is corrected with the coin data. Therefore, if some genuine coins are inserted after operating the switching means, the coin determination data will be corrected in the correct direction.

(F) Example FIG. 1 shows a coin sorting device (1) to which the present invention is applied, in which the inspection coins inserted into the coin slot (2) are rolled on the coin rail (3). Sensor (4),
The characteristics such as material, plate thickness and diameter are measured by (5) and (6). Sensors (4), (5),
(6) forms an oscillating magnetic field, and measures each characteristic of the inspection coin by grasping the degree of influence of the passage of the inspection coin on the oscillating magnetic field by the change in frequency, voltage, phase, and the like.
It is known that which of the characteristics of the inspection coins the sensors (4), (5), and (6) measure depends on the oscillation frequency, the shape of the coil, and the mounting position of the sensor. . In this example, the sensor (4)
Has an oscillation coil connected to an oscillator (7) which oscillates at a relatively low frequency such as 3 KHz. Since the magnetic flux induced by such an oscillation frequency penetrates the coin, the degree of influence of the inspection coin on the oscillation magnetic field depends on its material, and the maximum frequency when the inspection coin passes through the sensor (4). By measuring with a measuring device (10), coin data about the material can be obtained. Sensors (5) and (6)
Connects each oscillator coil to an oscillator (8) (9) that oscillates at a relatively high frequency such as 1 MHz, and the magnetic flux induced by such an oscillation frequency penetrates only near the surface of the coin. do not do. Therefore, if the sensor (5) is connected to the oscillator (8) with a pair of oscillation coils connected in series and in reverse phase, and the inspection coin passes between the coils, the influence of the passage on the oscillation magnetic field is reduced. It depends on the respective distances from both coils to the coin, and this degree of influence indicates the plate thickness of the inspection coin. Therefore, by measuring the maximum frequency when the inspection coin passes through the sensor (5) with the measuring device (11), the coin data regarding the plate thickness can be obtained. Further, although the sensor (6) is a single oscillation coil, the sensor diameter is made larger than that of coins and the sensor rails (3) are arranged at a small clearance from the coin rail (3) so that the area facing the inspection coin has an outer diameter. If it is set differently depending on the above, the degree of influence of the inspection coin on the oscillating magnetic field depends on the outer diameter of the inspection coin. Therefore, the coin data about the diameter can be obtained by measuring the maximum frequency when the inspection coin passes through the sensor (6) by the measuring device (12).

The data processing device (13) includes measuring devices (10), (11),
When each coin data is introduced from (12), memory (14)
The coin determination data is read from and compared with each other, and if both data match within the allowable range, the inspection coin is determined to be proper. The memory (14) stores 15 types of reference data as coin judgment data corresponding to the coin types A, B, C, D and E to be selected for each characteristic of material, plate thickness and diameter. ,
When the coin data is introduced from the measuring device (10), the data processing device (13) reads out the coin judgment data regarding the material for each coin type from the memory (14) and compares them.
If any coin determination data matches within the allowable range, it is determined in the material inspection that the inspected coin is the type of coin associated with the matched coin data. Further, when the coin data is introduced from the measuring device (11), the data processing device (13) reads out the coin judgment data regarding the plate thickness of each coin type from the memory (14) and compares the coin judgment data with any coin judgment. When the coins match with the data within the allowable range, it is determined that the coin is the type of the coin data. Similarly, when the coin data is introduced from the measuring device (12), the coin judgment data regarding the diameter is obtained. Make a comparison of. The inspection coin thus inserted from the coin insertion slot (2) rolls on the coin rail (3) and each sensor (4), (5),
While passing through (6), the data processing device (13) performs each of the comparison operations described above, and it is shown that the discrimination results of the material, plate thickness, and diameter are all the same kind of coin. Open the coin gate (15) with proper inspection coins. As a result, the inspection coin that has finished rolling of the coin rail (3) is received in the device. However, if different results are obtained in each determination, or if there is at least one inconsistency between the coin data and the coin determination data, the data processing device (13) determines the inspection coin as a false coin. At this time, since the data processing device (13) holds the coin gate (15) in a closed state, the coins rolled on the coin rail (3) are returned.

The above comparison operation will be described with reference to FIG. 2. AS ₁₁ is coin determination data for determining whether the inspected coin is a type A coin in the material inspection, and as described above, the memory (14).
Is stored in, and a ₁₁ is data indicating an allowable upper limit when comparing the coin data and the coin determination data, and this data is set in the program of the data processing device (13). Therefore, when the coin data is introduced from the measuring device (10), the data processing device (13) receives the memory (1
4) The coin judgment data AS ₁₁ is read out and compared, and depending on whether the coin data is within the range of a ₁₁ with respect to AS ₁₁ respectively, that is, whether the coin data is within AS ₁₅ to AS ₁₄ , the inspection coin is In the material inspection, it is determined whether it is a type A coin. The present invention is characterized in that when an inspection coin is inserted and the coin data obtained by this coin satisfies a certain standard, the coin determination data is corrected by this coin data. As this criterion, a second range narrower than the allowable range is set, and when the coin data is included in this second range, the coin data is used in preparation for the next inspection coin. Correct the judgment data. The fact that the coin data satisfies the second range, which is narrower than the allowable range, means
This inspection coin is a genuine coin with little wear and dirt,
By correcting the coin determination data with the coin data obtained from such coins, it is possible to effectively deal with the change over time of the coin sorting device. The data processing device (13) also programs the data a ₁₂ whose value is sufficiently smaller than the data a _{11 in} order to define this second range. And the data processing device (1
In 3), coin types A, B, and
C, D, with respect to E, (a ₁₂ mentioned above, if the Type A coin material) data defining a data and a second range (A species a ₁₁ mentioned above, if the material of the coin) for defining the allowable range, respectively Is programmed. Therefore, as shown in FIG. 4, the inspection coin passes through the sensor (4) and the measuring device (1
When the coin data SD ₁ is obtained in (0), the data processing device (1
In 3), this data SD ₁ is from (A to D) S ₁₄ to (A to D) S ₁₅

_Depending on whether it also belongs to ₁₃ , it is determined whether or not to correct the coin determination data that is the reference of this allowable range in the coin data SD ₁ . That is, the coin data SD ₁ is within the allowable range AS _{14 to} AS ₁₅
And if any of the second ranges AS _{12 to} AS ₁₃ is satisfied,
Correct the coin judgment data AS ₁₁ with the coin data SD ₁ .
In addition, the inspection coin passes through the sensor (5) and the measuring device (1
When the coin data SD ₂ is obtained in 1), the type of the inspection coin is determined according to which of the allowable ranges from (A to D) S ₂₄ to (A to D) S _25, and the allowable range of belonging is determined. Depending on whether it also belongs to the corresponding second range (A to D) S ₂₂ to (A to D) S _23, it is determined whether or not the coin data SD _{2 is} to correct the coin determination data that is the reference of this allowable range. . Likewise inspected coins measuring device through a sensor (6) to (12) of the coin data SD ₃ obtained coin data SD ₃ (to D) S ₃₄
To (A-D) S ₃₅ and (A-D) S ₃₂ to (A-D) S ₃₃ , it is determined whether the coin type and the coin determination data need to be corrected. The coin type E is omitted in FIG.

In this way, the coin judgment data is corrected when a genuine coin whose coin data satisfies the second coin is inserted. However, the coin judgment data is corrected, and it is left unused and used for a long time. In some cases, the coin judgment data may be inappropriate. At this time, the changeover switch (1

The coin type for which the coin determination data is to be corrected is designated by and the genuine coin of this coin type is inserted through the coin insertion slot (2). Then, when the data processing device (13) obtains the coin data of this coin to each of the measuring devices (10), (11), (12), the coin data does not satisfy the allowable range or the second range. Also, the coin judgment data is corrected by rewriting the data in the memory (14) stored so far as the data of the designated coin type.
