Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an automatic restart and stop method in the event of a power outage in a vending machine or the like.

Power outages usually occur when you least expect it.

For example, power outages may occur in vending machines, automatic teller machines, currency exchange machines, etc. (hereinafter referred to as vending machines) when they are on sale and not being used by customers, or while they are being used by customers and are operating. It is possible to do so. If a power outage occurs while the machine is not being used by a customer, there will be no problem with the machine itself, and no trouble will occur between the machine and the customer, even if the machine automatically returns to normal operation when the power is restored.

On the other hand, if a power outage occurs while the vending machine is in operation, and the vending machine is automatically restarted when the power is restored, there are various possible conditions of the vending machine at the time of the power outage. Unforeseen circumstances may arise, such as release data becoming haphazard, or troubles occurring with customers.

Conventionally, even though the above-mentioned problems could occur in the event of a power outage, all vending machines were automatically reset when power was supplied. For this reason, for example, when sales data and cash do not match, it is impossible to know whether the cause is due to a power outage, and management tends to be sloppy. Also, troubles between customers and staff had to become one-sided. Therefore, in view of the above, an object of the present invention is to provide a simple hakama for vending machines, etc., which instantly detects whether the vending machine, etc. has been used during a power outage, and automatically restores or discontinues sales depending on the state. The aim is to provide an automatic return and stop system when the power is cut off.

The present invention will be explained below based on embodiments shown in the drawings.

In FIG. 1, reference numeral 1 denotes a power supply device, into which a commercial power supply 2a is input, and at least two channels 3a, 3b of DC fin sources having different voltages are outputted based on the input. 4 is a circuit operated by the power supply of channel 3a, and 5 is a circuit operated by the power supply of channel 4a.

6 is a circuit that detects whether a vending machine, etc. is in use or not when there is a power outage, and if it is in use, it memorizes it and prevents it from automatically returning even if the power is connected again. , this circuit 6 is channel 3 of low pressure
means for flowing current only from a to the high voltage channel side;
A means for connecting a low voltage channel and a high voltage channel based on the signals output during operation of the device, and a means for storing when current flows from a low voltage channel to a high voltage channel. It consists of a memory means for storing information.

Figure 2 shows the relationship between power on and output of the power supply device. When commercial power supply 2a is input, DC power is output to low voltage channel 3a after a delay of, for example, 3 seconds from that input. When the power source has finished rising, a DC power source is output to the high voltage channel 3b. Also, when commercial power is cut off, the power to high voltage channels is cut off approximately 50 milliseconds after that, and the power to low voltage channels is cut off approximately 10 milliseconds after that. . Reference numeral 7 denotes a relay that is activated by a signal output during the operation of the device, for example, in the case of a vending machine (this case will be described below), a sales signal 8a output from the time a coin is inserted until the time when the article delivery is completed; sales signal 8
It acts upon output of signal a to close contact 7r shown in FIG.

Reference numeral 9 in Figure 4 is a diode that serves as a means to flow current only from the low voltage channel 2 channel 3a to the high voltage channel 3b. Since channel 3a has a low voltage, no current flows. 10 is channel 33
This relay 10 is an IJ relay that stores information when current flows from channel 3a to channel 3b. momentary power outage,
When a voltage is applied to channel 3a and the voltage in channel 3b is cut off, the instantaneous current that flows acts to close and hold contact 10r in FIG. 5.

When the contact 11r closes when the release switch is operated, the contact 10r is thereby released. When the contact 10r is closed, a lamp is displayed when power is supplied again, and a sales stop signal 12a is output in the evening so that the vending machine does not start selling. If there is a power outage while the vending machine is in operation, the vending machine will stop selling and will not be able to start selling even when power is supplied again. On the other hand, if the power goes out to 0 while the vending machine is not in operation, the relay 7 in Figure 3 is not working, so the contact 7r
is not closed, and therefore, the commercial power supply 2a is interrupted and the voltage is applied to the low voltage channel 3a, and the voltage of the high voltage channel 3b is cut off, causing the voltage to be lower than that of the channel 3b. That is, even if the voltage becomes zero, no current flows from channel 3b to channel 3a, and therefore, relay 10 does not operate and contact 10r does not close.

Therefore, even if the power is supplied again, the sale stop signal 12a is not output, and the vending machine is automatically returned to the sale state without stopping the sale. It should be noted that the present invention is not limited to the above embodiments, and it goes without saying that changes such as replacing the contact 7r with a transistor can be made.

As is clear from the above description, according to the present invention, it is possible to easily detect whether or not a device such as a vending machine is in operation, and automatically restore the vending machine or stop selling the vending machine.
