Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a raw material discharge control device for a vending machine that is configured to properly discharge raw materials such as sugar, powdered coffee, etc. and cook them into a prescribed beverage before selling them each time they are sold. It is.

By the way, in the case of such a vending machine, for example, if you press the selection button for coffee with milk or sugar, and then operate the sugar increase or decrease switch, the amount of sugar will be lower than if you only press the above selection button. The quantity is increased or decreased and transported to meet the preferences of the purchaser.

However, in this type of vending machine, once the increase or decrease switch is operated, even if the operation is incorrect, it cannot be corrected, and instead, the product may be sold against the buyer's wishes. It had the disadvantage that it had to be put away.

The present invention was invented in view of the shortcomings of conventional vending machines, and it attempts to carry out the discharge of raw materials by giving priority to the switch operated last, and also makes it possible to correct the switch operation. This is intended to notify the period.

Hereinafter, one embodiment will be described in detail with reference to the accompanying drawings.

The attached drawings show a raw material delivery control circuit for a vending machine according to the present invention, and in this embodiment, only the sugar delivery system is shown.

In the figure, 1 is a product selection switch for coffee with milk and sugar, which is a typical drink of this type of vending machine, and 2 and 3 are sugar increase and decrease switches.

Reference numeral 4 denotes a one-shot multi-bye break which outputs an operation signal S for a predetermined period of time when the product selection switch 1 is turned on.

5 is an oscillator circuit that outputs a clock signal C with a constant period, and only when the operation signal S is inputted to the next stage gate I circuit G1, the clock signal C is quantified or increased in the timer circuit 6. and weight loss counter 7.8 and 9
It is designed to be delivered to

Reference numerals 10 and 11 are RS flip-flops (hereinafter simply referred to as FF), and when the increase and decrease switches 2 and 3 are turned on and a selection signal is input from the S input terminal, the set state is established, and the respective Q outputs. A signal is output from the terminal, and the signal is distributed to the R input terminal of the other party to reset the FF of the other party.

In short, the operation of switches 2 and 3 is memorized and the memory of the other one is canceled.

The metering, increasing, and decreasing counters of the timer circuit 6 output time-up signals Ul, U2, . U3
The size of the counted quantity is related to the increase counter, quantitative counter, and decrease counter.

12 is a process for appropriately processing the signals obtained from these counters 7, 8 and 9, the one-shot multivibrator 4, and each FF 10 and 11, and operating the drive circuit 14 of the sugar unloading machine 13 and the correction alarm 15. The circuit is composed of gate circuits G2 to G7.

The above-mentioned correction alarm may be of a type that displays text or a type that emits a sound, and in short, it notifies the purchaser of this while the increase and decrease switches 2 and 3 are operable. It is enough to inform.

Note that this operable period is left to the counting operation of the weight loss counter 9.

16 is an inverter circuit which, when the operation signal S of the one-shot multivibrator 4 is deactivated, inverts it and gives a reset signal to each of the counters 7 to 9, returning the count value of each counter to "0". It is something that makes you

The present invention is constructed as described above, and its operation will be explained below.

(1) When purchasing a fixed amount of sugar milk coffee: When the product selection switch 1 is turned on, the one-shot multi-by-break 4 starts outputting the operation signal S.

Then, the quick signal S from the oscillator 5 is inputted to each of the counters 7 to 9 in the timer circuit 6 through the gate circuit G1, and each of the counters 7 to 9 starts counting operations.

Moreover, at the same time as the above-mentioned operation signal S is output, such signal S
is applied to one input terminal of the gate circuit G7, but since the weight loss counter 9 has not yet outputted the time-up signal U3, this is inverted and output to the gate circuit G7.
Since the notification signal F is outputted from the gate circuit G7, the correction alarm 15 is activated through the drive circuit 14 to notify that it is the period in which the sugar increase/decrease switch can be operated. Begin to.

On the other hand, the operation signal S is applied to one input terminal of the gate circuit G6, and at this time, both of the metering, increasing and decreasing counters 7.8 and 9 receive the time-up signal Ul,
Since U2 and U3 are not output, each gate circuit G
2. Since G4 and G5 do not output signals and are inverted and applied to the other input terminal of gate circuit G6, unloading signal E is output from gate circuit G6 and drives the sugar unloading machine 13 in the next stage. start.

Therefore, the sugar carrying machine 13 starts carrying out the sugar.

Of course, when the product selection switch 1 is turned on, both the milk and powdered coffee delivery machines and the water heater (not shown) start operating, and the respective raw materials begin to be mixed with the sugar in the mixing bowl.

In this way, when the product selection switch 1 is turned ON, the counters 7, 8 and 9 can perform counting operations, the sugar unloading machine 13 can perform unloading of sugar, and the correction alarm 15 can operate the sugar increase/decrease switch. The notification of each period will start, but as the counting operation of each of the above counters progresses and the count of the weight loss counter 9 ends,
The time-up signal U3 is output from the weight loss counter 9, and this signal U3 is inverted and applied to the other input terminal of the gate circuit G7, so that the gate circuit G7 outputs the notification signal F that had been output until then. The power is turned off to stop the operation of the result correction annunciator 15.

On the other hand, the time-up signal U3 is sent to the gate circuit G2.
．． G4 and G5, but the gate circuit G2.
In G4, the time-up signals U1 and U2 are not given from the metering and increasing counter 7.8, and
Since the gate circuit G5 is not given a signal from FFII, each gate circuit G2. Since signals are not yet output from G4 and G5, the unloading signal E is still output from the gate circuit G6, and the sugar unloading machine 13 is driven.

When the above-described operation continues until the quantitative counter 7 completes its counting operation, the quantitative counter 7 outputs a time-up signal U1, which is applied to the gate circuit G2.

This gate circuit G2 has already received the above-mentioned time-up signal U3.
Since the gate circuit G2 receives the inverted signal from the Q output terminal of the FF10 which is not in the set state, the gate circuit G2 outputs an unloading stop signal at the same time it receives the time-up signal U1. In order to apply the inverted signal to the other input terminal of the gate circuit G6, the gate circuit G6 simultaneously deactivates the unloading signal E and outputs the unloading signal E to the sugar unloading machine 13.
Stop the drive and finish transporting the sugar.

Of course, at the same time as the sugar delivery machine 13 stops driving, the milk and powdered coffee delivery machine and water heater also stop driving, and the mixing bowl pours the cooked drinking water (milk, sugar-added coffee) into the sales outlet. Pour into the loaded cup (not shown).

Thereafter, in this embodiment, the increase counter 8 continues to perform a counting operation, but the one-shot multivibrator 4 returns to its original state immediately after the counting operation ends, and the operation signal S is turned off. do.

Coupled with this deactivation of the operation signal S, the inverter circuit 16
A reset signal is given to each counter 7 to 9,
Each counter is returned to the "0" state.

This concludes the sale of a certain amount of sugar, milk, and sugar-infused coffee.

(2) When purchasing increased or decreased amount of milk sugar coffee: During the operation of purchasing the milk sugar coffee described in item (1) above, when the weight loss counter 9 finishes counting, Until the correction alarm 15 stops operating, the sugar increase and decrease switches 2 and 3 can be operated.

Therefore, if the increase/decrease switch 2 is turned on while the increase/decrease annunciator 15 is operating, the FFIQ will be in the set state and a signal will be output from its Q output terminal.
The signal is applied to the reset input terminal R of the gate circuit G2 to maintain it in the reset state, while the signal is inverted and applied to one input terminal of the gate circuit G2, and the signal is applied to the other two input terminals of the gate circuit G2. The gate circuit G3, which is applied to one input terminal of the gate circuit G3 and pasted thereon, is placed in a standby state in which it can output a signal when the time-up signal U2 is applied from the increase counter 8. To set/become.

Thus, by operating the increase switch 2, the sugar unloading machine 13 is set to the increase discharge state in which it is driven for a longer time than in the fixed quantity mode. If the amount is incorrect against the purchaser's will, the amount can be corrected by operating the weight reduction switch 3, of course, while the correction alarm 15 is operating.

That is, after operating the increase switch 2, turn on the decrease switch 3.
Then, FFII enters the set state and outputs a signal from its Q output terminal, and uses this signal to reset FFIQ, which had been in the set state until then, and also causes the gate circuit G5 to receive the time-up signal U3 from the reduction counter 9. When input, it enters a standby state where it can output a signal.

On the other hand, since the above FFIQ is reset as described above,
Gate circuit G2. Deactivate the signal to G3.

In addition, as described above, after operating the quantity increase/decrease switch 2゜3, if the amount of sugar can be fixed after all, the product selection switch 1 can be changed again to the correction alarm 15.
It is best to operate it while it is running.

That is, when the increase and decrease switches 2 and 3 are operated and either FF10 or 11 is in the set state, when the product selection switch 1 is turned on, the FFI O is turned on through the diodes DI and D2. A reset signal is applied to each reset input terminal R of , FFI 1, and each FF immediately enters a reset state, and as a result, the drive of sugar unloading machine 13 is controlled by the continuous operation time of metering counter 7.

Now, as mentioned above, turn on the increase switch 2 and
0 is set. In this case, when the counting operation of each counter advances and the weight loss counter 9 finishes counting and outputs the time-up signal U3, the time-up signal U3 is inverted. Since the signal is applied to the other input terminal of the gate circuit G7, the gate circuit G7 deactivates the notification signal F that has been outputted up to that point, and as a result stops the operation of the increase/decrease annunciator 15.

On the other hand, the time-up signal U3 is the data 1-circuit G.
2. G4. and G5, but the gate circuit G2. G4 is not given the time-up signals Ul and U2 from the metering and increasing counter 7.8, and gate circuit G5 is not given any signal from FF1l, so each gate circuit G2. G4 and G
No signal is output yet from G5 to gate circuit G6.
The sugar unloading signal E is still output and drives the sugar unloading machine 13.

Further, when the counting operations of the counters 7 and 8 progress and the counting operation of the quantitative counter 7 is completed, a time-up signal U1 is outputted and the signal U1 is inputted to the gate circuit G2. Since the signal from the Q output terminal of FFl0 is inverted and is in a non-conducting state to one input terminal of circuit G2, no signal is output from gate circuit G2. ．． Since no signal is output from G5, the gate circuit G6 continues to output the unloading signal and continues to drive the sugar unloading machine 13.

When the above-described operation is continued and the increase counter 8 finishes counting, the time-up signal U2 is outputted from the increase counter 8 and applied to the gate circuit G3.

Then, in gate circuit G3, FF10 is applied to one input terminal.
Since more signals are given, output the signal immediately,
Such a signal has already been input to one input terminal as a time-up signal U.
3 to the other input terminal of the gate circuit G4, which causes the gate circuit G4 to output an unloading stop signal.

When the gate circuit G6 receives the unloading stop signal inverted, it stops the unloading signal E that has been outputted up to that point, and stops driving the sugar unloading machine 13.

Of course, the drive of the milk/powdered coffee conveyor and water heater is also stopped as appropriate before and after the sugar conveyor 13 is stopped.

Immediately after the counting operation of the increase counter 8 ends, the operation signal S of the one-shot multivibrator 4 is also deactivated, and in conjunction with this, a reset signal is given to each counter 7 to 9, so that the counters 7 to 9 are reset to zero. ”.

This concludes the sale of coffee with milk and sugar added with an increased amount of sugar.

Next, as described above, turn on the weight loss switch 2 and
(Of course, even in this case, as long as the correction alarm 15 is in operation, the increase/decrease switch 2 is turned on again to set FF10 and carry out an increase in the amount of sugar. system),
In this case, when the operation of each counter progresses to Call 1 and the weight loss counter 9 finishes counting and outputs the time-up signal U3, the correction alarm 15 naturally stops its operation. However, at the same time, the time-up signal U3 is input to the other input terminal of the gate circuit G5, which has already received a signal from the FF11 to one input terminal, and the gate circuit G5 simultaneously receives the signal from the FF11. outputs an unloading stop signal.

The gate circuit G6 inverts and receives this unloading stop signal, thereby stopping the unloading signal E that has been outputted up to that point and stops driving the sugar unloading machine 13.

Of course, the drive of the milk/powdered coffee conveyor and water heater is also stopped as appropriate before and after the sugar conveyor 13 is stopped.

Thereafter, immediately after the counting operation of the increase counter 8 ends, the operation signal S of the one-shot multivibrator 4 is also deactivated, and in conjunction with this, a reset signal is given to each counter 7 to 9, and the value returns to 440 +1. do.

This concludes the sale of milk sugar coffee with reduced sugar content.

Since the present invention is constructed as described above, the purchaser can correct the switch operation, and is also able to know the period during which the correction can be made, which makes it possible to provide an extremely convenient raw material delivery device. It's an invention.
