Description

[Detailed Description of the Invention] (a) Field of Industrial Application The present invention relates to a coin processing device equipped with a coin detection device that checks the material of coins introduced into a coin passage.

(b) Conventional technology Conventionally, a coin detection device is provided to check the material of the coin introduced from the rotary disk into the coin passage, and when this coin detection device detects a counterfeit coin, it outputs a signal.
A coin processing device configured to eliminate such counterfeit coins is known, and is disclosed in, for example, Japanese Utility Model Application Publication No. 57-6703.

(c) Problems to be Solved by the Invention Since the coin detection device in the prior art is configured to electrically analyze and check the material of the coin, the device is complicated and expensive. Furthermore, when a different denomination signal is output, the shutter provided at the bottom of the stacking cylinder is opened to release the counterfeit coins, which may result in genuine coins being released as well.

In view of the above, the present invention provides a device that can easily and reliably remove only counterfeit currency with a simple and inexpensive configuration.

(d) Means for solving the problem Explaining based on an embodiment, the magnet 1 is provided oppositely on the coin passage 4 near the coin outlet 8.
2, a prevention member 13 that is interposed between the magnet 12 and moved to attract it when a magnetic counterfeit coin conveyed through the coin passage 4 is attracted to the magnet 12; A push button 10 moves a prevention member 13 so that the attracted counterfeit coins separate from the magnet 12 and fall into the coin extraction port 8, and the counterfeit coins are attracted to the magnet 12 by being operated by the movement of the prevention member 13. and a stop signal generating device 16 which outputs a stop signal to stop the drive of the rotary disk and stops outputting the stop signal when a counterfeit coin is separated from the magnet 12.

(e) Effect This invention provides a magnet in the coin passage to attract magnetic counterfeit coins, and when the magnetic counterfeit coins are attracted to the magnet, the drive of the rotary disk is stopped and the magnetic counterfeit coins are separated from the magnet. By discharging the coins to the coin outlet, the rotary disk can be driven again and the material of the coins can be checked.

(f) Examples Examples thereof will be described in detail below based on the drawings.

FIG. 1 is an external view of the coin processing device A viewed from above. 1 is a machine frame of a coin processing device, and on the top surface of this machine frame 1 is a rotary plate 2 having an appropriate frictional force.
is provided so as to be rotated in the direction of the arrow by a drive device (not shown) such as a motor. Coins C are blown toward the outer circumferential surface of the rotary disk by the centrifugal force of the rotary disk 2, and the coins C are slid into contact with the coin guide members 3, aligned, and transferred to the coin transfer path described below. Leads to 4. Reference numeral 4 denotes the above-mentioned coin transfer passage, which is opposed to a guide plate 5 which is operated in conjunction with a handle (not shown) that is operated according to the denomination, in such a manner that the gap between the guide plate 5 is changed. It is formed by a sliding piece 6 that is Reference numeral 7 denotes a transfer device that transfers the coins guided into the transfer coin passage 4 toward the coin takeout port 8 while being pressed from above. At the same time, one of the rollers is driven by the drive device (not shown).

Therefore, although not shown, the coins transferred one by one by the transfer device 7 are engaged with a star wheel rotating at a certain angle, and the rotation of the star wheel is counted by a counter or a proximity switch. You can easily check this.

9 is a coin transferred by the transfer device 7
A coin detection device 9 detects counterfeit coins made of iron or the like mixed in C'. A confirmation press button 10 is attached to the upper part of the coin transfer passage 4 in such a manner as to protrude upward.

FIG. 2 shows the structure of the coin detection device 9. Reference numeral 11 denotes a housing that constitutes a part of these coin detection devices 9. On the inner wall surface of the housing, when the counterfeit coins made of iron or the like are transferred to the lower surface of the housing, a member 13 described below is provided to prevent these counterfeit coins from being transferred to the lower surface of the housing.
Magnet 12 that attracts while pushing upward
is fixed. 13 is a prevention member that prevents the counterfeit currency from being directly attracted to the magnet 12;
The prevention member 13 is suspended to a shaft member 14 fitted through the approximate center of the housing 11 to such an extent that it does not interfere with the flow of coins C transferred to the coin passage 4. On the other hand, the above-mentioned confirmation press button 10 is fixed to the upper end of the shaft member 14, and an elastic member 15 is wound around the shaft member 14 between the confirmation press button 10 and the housing 11. It is provided.

Reference numeral 16 denotes a stop signal generating device that outputs a stop signal to the aforementioned drive device (not shown) in conjunction with the prevention member 13 that is pushed up when the magnet 12 attracts counterfeit cargo.

In the above configuration, next
The operation of the present invention will be described mainly using diagrams.

First, the coin C sent out from the rotary disk 2 is transferred by the above-mentioned transfer device 7 within the transfer coin passage 4 toward the coin outlet 8. In this process, if counterfeit coins made of iron or the like are mixed into the transferred coins C', the coin detection device 9 will adsorb the counterfeit coins C'' in the state shown in Fig. 3. On the other hand, at this time, the stop signal generating device 16 also
Since the actuator member 17, which constitutes a part of 2
A stop signal is output to a drive device (not shown) that drives the device, etc., to cause the device to stop.

Therefore, the user who is using these coin processing devices A sees these stopped states and assumes that there are counterfeit coins C'' mixed in with the coins, so that these counterfeit coins can be removed by the coin detection device 9. Then, press the confirmation push button 10 downward.Then, the counterfeit coins that are attracted to the magnet 12 through the prevention member 13 are removed.
C'' falls in the direction of the coin outlet 8 indicated by the arrow in the shape shown in Figure 4. Therefore, after the user confirms these falling coins, the contents counted by the counter or proximity switch etc. are false. Accurate counting information can be obtained by subtracting -1 from these contents, assuming that the counting contents include coins.On the other hand, in the case of the stop signal generating device 15, the prevention member is activated by pressing the confirmation press button 10. 13 returns to its original position, the actuator member 17 also returns to its predetermined position by itself. Therefore, at this point, the output of the stop signal is erased, so the user must operate the start switch (not shown) again. Then, the coin counting operation can be restarted.

In the above implementation, the coin detection device is provided after the transfer device 7, but this does not necessarily mean that it must be provided at these positions.

For example, if the coin to be transferred is located in the coin passage, it may be provided at any position in the coin passage. Furthermore, the stop signal output from the stop signal generator may be used not only as a stop signal for a drive device such as a motor, but also as a lighting signal for a trouble lighting device.

(g) Effects of the invention As described above, the invention provides a magnet in the coin passage to attract magnetic counterfeit coins, and when the magnetic counterfeit coins are attracted to the magnet, the drive of the rotary disk is stopped and the magnetic counterfeit coins are removed. By separating the coin from the magnet and ejecting it to the coin ejection port, the rotary disk can be driven again and the material of the coin can be checked, so it is easy to identify counterfeit coins with a simple and inexpensive structure. It has the effect of being able to be removed reliably.
