JPS5825307B2 - Vending machine change sending error handling method - Google Patents

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a change sending error handling method for a vending machine. Conventionally, in a vending machine, when the amount of change to be returned is small due to, for example, an electrical system failure, etc. is often the case.

In this case, the staff will give you the change for the shortage each time.
A predetermined amount of coins is sent out to the user by a single operation of putting out coins one by one.

However, this one-shot operation is often performed without the device itself checking how many sheets have been ejected, so there is a risk that the amounts will not add up when totaling up.

The present invention has been made in view of the above circumstances, and its purpose is to reduce the number of change for each coin when the change is not sent at all due to an electrical system failure, or when there is a shortage of change. To provide a change sending error processing method for a vending machine capable of improving the precision of a single operation by storing the remaining amount and performing the single operation, and resolving mismatches in amount verification during aggregation.

An embodiment of the present invention will be described below with reference to the drawings.

In the figure, 11 is a change sending circuit provided in the vending machine, 12 is an arithmetic circuit that performs various calculations described later, and 13
is a storage device 1 for storing the calculation results of this calculation circuit 12;
Reference numeral 4 denotes a single operation device that sends out change one by one when there is a shortage of change, and 15 refers to a change that sends out change in response to a change sending command from the change sending circuit 11 and the single operation device 14. It is a mechanism.

The change sending circuit 11 includes, for example, a counter 16 and a change sending command section 17.

The counter 16 stores the number of change by receiving a signal for the number of coins to be dispensed, which is supplied from a control unit of a vending machine (not shown).

Further, the change sending command unit 17 issues a change sending command to the change mechanism 15 based on the contents of the counter 16.

On the other hand, the arithmetic circuit 12 is inputted with a certain setting value, that is, the limit amount of change that can be sent out (in this embodiment, this setting value is the input amount, for example, 100 yen), and this setting value (100 yen ), the computation result (complement) is stored in the storage device 13, and the stored contents are compared with the set value.

Furthermore, the single-shot operation device 14 single-handedly dispenses change one piece at a time to the change mechanism 15 until the stored content of the storage device 13 matches the set value, that is, until a matching signal is output from the arithmetic circuit 12. It performs the operation to send the data.

Furthermore, the change mechanism 15 sends change out of the vending machine based on the change sending command from the change sending circuit 11 and the single operation device 14, and the change sending circuit 15 sends change out of the vending machine every time one piece of change is sent out. For the counter 16 of
A sending confirmation signal is sent to reduce the contents one by one.

Next, we will explain the operation in such a configuration.
Here, we will explain the case where, for example, you insert a 100 yen coin and purchase something worth 40 yen.

In this case, the change is 60 yen.

The number of change (change coin pattern signal) is supplied from the control section (not shown) to the counter 16 and stored therein, as described above.

Various combinations of change (60 yen) are possible depending on coins of 5 yen, 10 yen, and 50 yen, but to simplify the explanation, a case will be described in which six 10 yen coins are sent out.

First, 16'' is stored in the counter 16 as described above.

and. Since the number of change is set in the counter 16, the change sending command unit 17 first sends a sending command to the change mechanism 15 to send out six 10 yen coins.

As a result, the change mechanism 15 sends out 10 yen coins one by one, and sends a delivery confirmation signal to the counter 16 each time delivery is confirmed.

Upon receiving this transmission confirmation signal, the counter 16 counts down the contents by "1".

Thereafter, when the contents of the counter 16 become "0", the change sending operation ends.

The above operation is a normal change sending operation, which is already well known.

Next, an explanation will be given of the operation when an error occurs in sending change and, for example, only 40 yen, which is 20 yen short, is sent.

In this case, even though the change sending command unit 17 has issued a change sending command to the change mechanism 15 multiple times, the change sending command unit shows that the content of the counter 16 is stopped at “2”. Confirmed on 17th.

Therefore, in this case, the change sending command unit 17
Give the change sending command to 5 several more times.

If the contents of the counter 16 do not change despite these several sending commands, the change sending command unit 17 indicates that there is a failure, for example, between the change sending command unit 17 and the change mechanism 15 or in the electrical system of the change mechanism 15. It is determined that this has occurred, and a signal indicating the shortfall of 20 yen is sent to the arithmetic circuit 12.

From then on, this route is operated until the content of the counter 16 becomes "0".

Therefore, the arithmetic circuit 12 calculates the complement of the shortfall of 20 yen to the set value of 100 yen, and stores the calculation result (complement 80 yen) in the storage device 13.

Then, the arithmetic circuit 12 matches the contents of the storage device 13 (80 yen) with the set value (100 yen), and drives the single-shot operation device 14 to dispense change until the two match.

That is, the arithmetic circuit 12 instructs the single-shot operation device 14 to be driven because the contents of the storage device 13 and the set value do not match.

Upon receiving this command, the single operation device 14 operates the change mechanism 15 to dispense one 10 yen coin.

As a result of this change sending, the sending confirmation signal is sent to the counter 6, so that the content of the counter 6 changes from "2" to "1".

Therefore, the change sending command section 17 sends the change to the arithmetic circuit 12 to
Sends a signal of 0 yen.

Then, the calculation circuit 12 again performs the same complement calculation as described above, and stores the calculation result (complement 90 yen) in the storage device 13.

In this way, the storage device 13 adds and stores the number of 10 yen coins each time one 10 yen coin is sent out, and when two 10 yen coins are sent out, the memory The content is [80 yen + 10 yen + 10 yen = 100 yen], which matches the setting value (100 yen), and the arithmetic circuit 12
outputs a match signal.

When this coincidence signal is sent to the single-shot operating device 14, the single-shot operating device 14 stops the change sending operation.

In the above embodiment, the single operation device 14 is connected to the arithmetic circuit 1.
Although the single operation device 14 is automatically operated by a signal from the device 2, it is not necessary to fully automate the single operation device 14.

For example, it is configured such that it is kept in a standby state ready for operation by a signal from the arithmetic circuit 12, and a single-shot operation is performed by an operation by an attendant, and when there is no signal from the arithmetic circuit 12, a single-shot operation can also be performed by an operation by an attendant. Device 14 may be inactive.

In this case, in general, if there is an abnormality in the vending machine, an attendant will always be present, so the risk of trouble occurring is further reduced.

Furthermore, in the above embodiment, a case has been described in which a preset setting value matches the content stored in the storage device, but the invention is not limited to this. A first storage device that stores the number of coins to be sent or a second storage device that stores the amount of each coin to be sent is provided, and when a change sending error occurs, the first storage device is provided.
The change may be dispensed by operating the single operation device until the contents stored in the second storage device match.

Furthermore, for example, the storage device is r+IJL. Even if the single operation device is operated until the storage device's own carry signal is output, the same object as in the above embodiment can be achieved.

Therefore, the present invention is not limited to the above-described embodiments, and it goes without saying that various modifications can be made without departing from the gist of the present invention.

As described in detail above, according to the present invention, when a change sending error occurs, it is possible to send out the amount of change that is insufficient by a single operation with high accuracy, and it is possible to resolve the discrepancy in amount verification at the time of aggregation. We can provide processing methods.
