Description

[Detailed explanation of the invention] This invention is a coin system that stacks coins of many denominations and stores them in a coin storage tube, and that a mechanism is installed at the bottom end of this storage tube to eject coins one by one. It concerns the release device.

The above-mentioned coin ejecting device is used, for example, in a dispensing machine at a bank, etc., but when the day's work is over and the coins stored in the coin storage tube are to be collected, the single coin dispensing mechanism is continuously driven. Coins are released until the stored coins are exhausted.

However, in the actual collection process, after the coin is released and the coin out detection sensor detects that the coin is out, the coin ejecting mechanism is driven more than 0 times as a dummy operation, so there is a lot of unnecessary driving and the amount of money is recovered. Processing was wasting time.

Therefore, in the above-mentioned collection process, this invention automatically stops the operation of the single coin dispensing mechanism in order from the coin storage tubes with no ejected coins among the coin storage tubes for each denomination, thereby eliminating the need for the single coin dispensing mechanism. To provide a coin discharging device capable of shortening processing time by minimizing driving, minimizing noise, and improving the durability of the device life.

This idea was developed by installing a single coin ejection mechanism for each denomination at the bottom end of a coin storage tube that stores a large number of coins of different denominations in a stacked manner. The ejecting device includes: a ejected coin confirmation sensor provided on the coin ejecting side of each lower end of the coin storage tube to detect ejection of coins of each denomination; and a driving means common to each of the single coin ejecting mechanisms. , A collection switch that is common to each of the above single coin dispensing mechanisms and operates the same mechanism at the time of collection, and each of the above-mentioned ejected coin confirmation sensors corresponding to each coin storage cylinder for each denomination detects the ejected coin. a storage means for storing, and a coin storage tube that transmits and controls the power of the drive means to a single coin ejecting mechanism corresponding to a coin storage tube which is stored in the storage means as having a coin to be ejected; The coin dispensing device is characterized in that it is equipped with a control means for automatically stopping the operation of the coin dispensing mechanism in order from .

According to this invention, when the recovery switch is pressed to operate the single coin ejecting mechanism, the storage means receives a detection signal indicating that no coins have been ejected from the ejected coin confirmation sensor provided on the coin ejecting side of the coin storage cylinder. for example
Since the operation of the coin dispensing mechanism is automatically stopped sequentially from the coin storage cylinder with no ejected coins through the RAM and the control means, for example, the CPU, the single coin dispensing mechanism only needs to be operated once. Minimal movements are required, processing times are significantly shorter, noise is kept to a minimum, and
This has the effect of improving the durability of the device life.

Furthermore, by providing a common drive means for each coin dispensing mechanism, this drive means can be shared by the mechanisms for each denomination, and the structure of the drive means can be made simple and inexpensive. There is.

The ROM 63 stores a program for coin discharging processing, and the RAM 64 as a storage means stores and reads necessary data, and also stores a flag F1.
-F5 are provided.

The RAM 64 mentioned above has each coin storage tube 28 for each denomination.
The fact that each of the above-described released coin confirmation sensors 35 has detected a released coin is stored in correspondence with A to 28E.

The transmission unit 65 transmits this coin ejecting device to the teller device 66.
The counter device 66 is, for example, a deposit/withdrawal machine, a payment machine, etc., and this coin discharging device dispenses coins based on data about the type of coins and the number of coins transmitted from the counter device 66 described above.

Of course, a key input device may be connected to this coin ejecting device to perform the coin ejecting process.

The collection control unit 67 controls the coin supply device 14 based on the detection by the overflow detection sensor 42 provided in the collection box 41.
At the same time, an overflow is displayed on the display unit on the teller device 66 side via the transmission unit 65, and each coin storage cylinder 2 is stopped based on the depression of the collection switch 8.
A command to release the coins stored in 8A to 28E to the tray 4 side is output.

The supply device control unit 68 controls each coin storage tube 28A to 28.
Based on the detection signal being output from the replenishment detection sensor 33 of E, the coin remaining amount detection sensor 69
While outputting a signal indicating the presence of coins, the first motor 20 is driven to drive the coin replenisher 14 to replenish coins. Since the coins stored in the coin supply device 14 are mixed coins of various types, this replenishment is performed for all coin storage cylinders 28A to 28E, and the coin storage cylinders 28A to 28E that first output the replenishment signal. The replenishment process is stopped when the full detection sensor 32 of 28E outputs a detection signal.

When the coin storage cylinders 28A to 28E become full due to coin replenishment, the distribution control unit 70 operates the solenoid 40 corresponding to this sensor 32 based on the signal from the full detection sensor 32, and distributes the subsequent replenishment of coins. is collected in the collection box 41 side.

The delivery control unit 71 controls the corresponding coin storage cylinders 28A to 28A based on the coin release command from the counter device 66.
In addition to driving the solenoid 53 of the coin storage tube 28E and the second motor 43 to perform the coin ejection process, the coin release process is also performed in response to a command from the recovery switch 8. In this case, the solenoid 53 of all coin storage cylinders 28A to 28E is activated. and drives the second motor 43 to perform the discharge process.

In this discharge process, the replenishment detection sensor 33
outputs a detection signal when the storage capacity is low,
The out-of-coin detection sensor 34 outputs a detection signal when the stored amount reaches an amount that is considered to be in an out-of-coin state, and stops the discharging process when these signals are output. Further, the ejected coin confirmation sensor 35 detects the coins ejected from each of the coin storage tubes 28A to 28E and outputs a detection signal, but the detection signal is output within a predetermined time even though the coin ejection process is performed. If not, it is determined that no coins have been ejected.

The pulse output from the pulse generator 61 instructs the operation of discharging coins each time.

The coin discharging device configured as described above stores coins of various coin types in the coin supply device 14 in a mixed state, and then distributes the coins to each of the coin storage tubes 28A to 28E to prepare for discharging the coins. The coin dispensing mechanism 30 is controlled based on dispensing data from the counter device 66 to discharge the corresponding coin.

In addition, a second motor 43 and a drive shaft 44 are connected to the single coin ejecting mechanism 30 for the coin storage cylinders 28A to 28E, which are stored in the RAM 64 as having ejected coins.
In addition to transmitting and controlling the power of the drive means equipped with
Coin storage cylinders 28A to 28E with no ejected coins
The above-mentioned CPU 62 performs control to automatically stop the operation of the coin dispensing mechanism 30 sequentially.

Next, a collection process for collecting each coin stored in each of the coin storage tubes 28A to 28E will be described with reference to the flowchart of FIG. 10.

The above-mentioned collection process is performed for each coin storage cylinder 28A to 28E.
The discharging process is stopped as soon as the coin discharging stored in the coin is exhausted.

In the above-mentioned collection process, the collection switch 8 is kept pressed down until the end, and if the collection switch 8 is released midway, the coin discharging operation is stopped at that point. 8 can be used for coin ejection testing.

First, in the collection process, the collection switch 8 is pressed down and maintained in that state.

By this operation, all flags F1 to RAM64 are
F5 is reset and each coin storage cylinder 28A to 28E
All discharged coin confirmation sensor 35 provided on the discharge side of
A level check is performed to check whether ... is operating normally and whether it is detecting the removal of coins.

If all of these sensors 35 are OFF, it is normal, and if even one is ON, it is an error, so the error display lamp 9 is turned on and the error is handled by the staff.

If all the aforementioned sensors 35 are normal, the second motor 43 is driven via the delivery control section 71 and a timer is set. Although this timer is not shown, it may be a soft timer or a hard timer, and it measures a predetermined time and within this time, the pulse generator 6
Check whether the pulse from 1 is output.

If the above-mentioned pulse output is not received within a predetermined period of time, it is assumed that the second motor 43 is malfunctioning or the transmission system is malfunctioning, and the error indicator lamp 9 is turned on, and the error is handled by a system member.

If there is a pulse output within a predetermined time, it is considered normal and each coin storage cylinder 2 is
Turn on solenoid 53 corresponding to 8A to 28E
Then, all the coin dispensing mechanisms 30 are driven to dispense one coin.

When the aforementioned single coin dispensing mechanism 30... starts operating, the timer is set again, and while this timer measures a predetermined time, it is determined whether each ejected coin confirmation sensor 35 detects a coin.

In this determination, if no released coin is confirmed even after a predetermined period of time has elapsed, it is determined that there are no more coins in the coin storage tubes 28A to 28E.

When the aforementioned sensors 35 detect a released coin, flags F1 to F5 of the RAM 64 are set in correspondence with the corresponding coin storage cylinders 28A to 28E.

That is, when the release of a 1 yen coin from the storage cylinder 28A is detected, flag F1 is set, and similarly when a 50 yen coin is detected, flag F2 is set, and in this way, each of the flags F1 to F5 for the corresponding coin is set. do.

It is normal to set each of the above flags while the pulse generator 61 outputs the next pulse, and if a predetermined period of time elapses without the above pulse being output, an error such as a coin jam may occur. It is determined that the error has occurred, and an error process is performed by the staff member.

When one coin is normally dispensed, various coins are discharged into the tray 4.

When the first coin is sent out, it is then checked whether the recovery switch 8 is kept pressed down.

If the collection switch 8 is open at this time, the delivery control section 71 turns off the second motor 43 and the solenoid 53 to stop discharging coins.
As a result, the releases to date have been temporary releases and are tests of coin release.

When the recovery switch 8 is kept pressed down, a check is made to see if each released coin confirmation sensor 35 is detected. In other words, each flag F of RAM64
Check whether 1 to F5 are set.

If each of the flags F1 to F5 mentioned above is set, the corresponding coin storage tubes 28A to 28E
Since it has not been confirmed that there are no more coins stored in the coin, each coin continues to be fed out one by one, and such one-by-one coin feeding is repeated in sequence.

When such a collection process is performed, the coins in each of the coin storage cylinders 28A to 28E disappear. This disappearance is detected when a timer is set and no detection signal is received from the released coin confirmation sensor 35 within a predetermined time.

When each of the above-mentioned sensors 35... does not detect a released coin within a predetermined period of time, the corresponding coin storage tubes 28A to 28
In order to stop the single coin dispensing mechanism 30 corresponding to E, the dispensing control unit 71 activates the corresponding solenoid 53.
Turn it off. As a result, the corresponding storage cylinder 28
The operation of discharging coins A to 28E is stopped.

Then, by stopping the single coin ejecting mechanism 30 of all the coin storage cylinders 28A to 28E,
All flags F1 to F5 in the RAM 64 are reset, the second motor 43 is turned off, and the collection process is completed.

As can be seen from this process, each coin storage cylinder 2
Each coin dispensing mechanism 30 corresponding to 8A to 28E
. . ., the blank dispensing operation is completed only once, that is, one blank dispensing operation is performed in which each discharged coin confirmation sensor 35 detects that no coin is discharged, and there is no needless blank dispensing operation.

In summary, each coin storage tube 28A for each denomination...
28E, each ejected coin confirmation sensor 35 detects that no coin is ejected, and the RAM 6
4. The operation of the single coin ejecting mechanism 30 is automatically stopped via the CPU 62 starting from the coin storage cylinder with no ejected coins, which minimizes unnecessary operations.
Processing time can also be extremely shortened compared to devices with conventional structures, and as a result, noise can be minimized and the durability of the device life can be improved.

In addition, drive means common to each of the above-mentioned single coin dispensing mechanisms 30, that is, a second motor 43 and a drive shaft 44.
By providing this, the driving means can be shared by the above-mentioned mechanisms 30 for each denomination, and the structure of the driving means can be made simple and inexpensive.

In the correspondence between the structure of this invention and the embodiment described above, the driving means of this invention is the second motor 4 of the embodiment.
Similarly, the storage means corresponds to the RAM 64, and the control means corresponds to the CPU 62. However, this invention is not limited to the configuration of the above-described embodiment.
