Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a control device for a vending machine, and more particularly to an improvement in a control device that examines the amount of change coins stored and determines whether a sale requiring change is possible.

In conventional vending machines, the detection of lack of change is possible only after the minimum amount (
For example, only one type of coin (10 yen) was used.

In other words, when the stored amount of 10 yen coins for change is less than the maximum change payout amount (9 10 yen coins), sales that require change are prohibited, and sales are only made when the input amount matches the set selling price. was allowed.

However, even if the stored amount of 10 yen coins becomes less than the maximum change payout amount, in reality, it is often possible to pay out change by combining the coins with other denominations of coins (for example, 50 yen coins).

For example, even if there are four 10 yen coins, one 50 yen coin satisfies the maximum change payout amount of 90 yen.

Despite having enough change coins in stock to actually dispense change by combining multiple denominations,
In the conventional case, this would be treated as a lack of change, resulting in the inconvenience of prohibiting sales.

This significantly reduces the vending efficiency of the vending machine.

The present invention has been made in view of the above-mentioned circumstances, and uses a combination of change coins of multiple denominations to determine whether there is a maximum change payout amount, and based on this determination result, the possibility of a sale requiring change is determined. It is an object of the present invention to provide a control device for a vending machine that makes judgments.

According to the present invention, the number of stored change coins is detected for each denomination and used for the above determination.

At this time, if the number of change coins is greater than a predetermined number, only the presence of the predetermined number is detected, and the detailed number is not detected.

If the number is below a predetermined number, the detailed number of stored sheets is detected.

This is because if the correct number of change coins is detected only when the number of change coins stored becomes small, it is possible to sufficiently deal with change shortages.

The invention will now be described in detail with reference to the embodiments of the accompanying drawings.

In Figure 1, the 10 yen coin for change is in the coin tube 1.
1, 50 yen coins for change are stored in coin tubes 12, respectively.

A position detection switch 13.14 provided in association with each coin tube 11.12 is inoperative when the number of 10 10 yen coins or 500 50 yen coins in each tube 11, 12 is less than a predetermined number N or M, N+1 or M+1
It works when above.

The predetermined numbers N and M can be any number.

For example, it may be 20 sheets or 10 sheets.

In FIG. 2, a 10 yen coin storage counter 15 for change is shown.
The 50 yen coin storage amount counter 16 for change is a preset type reversible counter that can perform addition and subtraction, and can preset a predetermined count value N or M.

When the position detection switch 13.14 operates, the output signal of the position detection switch 13.14 falls from %t, // to 20", and these signals are transferred to the inverters 17, 1.
Each is inverted at B.

That is, the outputs of the inverters 17 and 18 rise from "10" to "1" when the position detection switches 13 and 14 operate.

The output signals of inverters 17 and 18 are applied to timers 19 and 20, respectively.

Timers 19 and 20 delay these signals for a certain period of time and apply them to the preset command inputs of counters 15 and 16, respectively.

As a result, the counter 15 has a count value N representing the number N.
However, the counter 16 is preset with a count value M representing the number M of sheets.

Even if the number of coins 10 or 50 in the coin tubes 11 and 12 is greater than N or M, the count value of the counters 15 and 16 will be N or M, but the predetermined value of N or M indicating that there are enough coins for change will be counted. Even if you sum it up by numbers, there will be no inconvenience in one stroke.

Furthermore, since it is not necessary to count an unnecessarily large number of numbers, the capacity of the counters 15 and 16 can be reduced (N-ary or M-adic may be used).

Counter 15 or 16 is set by inputting a preset command.
holds a predetermined value N or M, the outputs of the inverters 21 and 220 are "0", and the AND circuit 23.2
4 becomes inoperable.

Therefore, even if the change payout instruction signal PO that instructs the counters 15 and 16 to perform a subtraction operation becomes N1, the counter 15.1
6 is not in a subtraction mode.

The payout slides 25 and 26 at the bottom of the coin tube 11° 120 are driven to send coins io and s from the change payout passages 27 and 2B.

When paying out some change, the coins 10.50 in the coin tubes 11 and 12 are N.
When the number of sheets or M sheets or less is reached, the position detection switch 13 or 14 is turned off, and the output of the inverter 17 or 18 becomes "10".

After timer 19,200 operating hours, timer 19°200
The output also becomes "0", and the preset command input to counters 15 and 16 makes a %S □" roar.

At the same time, the AND circuits 23 and 24 become operational, and the signal P
O power? ■ If “,” then counters 15 and 16 are set to subtract.

When the change payout detection switch 29.30 provided in the change payout passage 27.28 is activated by the payout change coin, a pulse of signal 1 is applied to the OR circuits 33, 34 via the inverters 31, 32, and the counter 15, Leads to 16 count inputs.

Therefore, after the amount of 10 yen coins stored is N or less or the amount of 50 yen coins stored is less than M, 1
The number of 0 yen or 50 yen coins is subtracted from the value N or M by the counter 15 or 16.

At this time, the contents of counters 15 and 16 represent the exact amount of coins stored.

When the change payout is completed, the signal PO becomes 0, and the counters 15 and 16 become ready to add.

When a coin is inserted from the coin slot of the vending machine in this state, the 100 yen coin detection switch 35
Alternatively, the 50 yen coin detection switch 36 or the 10 yen coin detection switch 37 is activated, and the inverters 38, 39.
A pulse of signal 1 is outputted via 40.

The outputs of inverters 39 and 400 are AND circuits 41.4 and 41.4, respectively.
Join 2.

If it is less than N or M, the output of timers 19 and 20 is 1.
110 //, the outputs of the inverters 43 and 44 are "1", and the AND circuits 41 and 42 are operable.

Therefore, the counters 15 and 16 add and count the number of sheets inserted.

This is because the inserted 1 and 0 yen coins or 50 yen coins are stored in the coin tubes 11 and 12, respectively, and the counters 15 and 16 add and count the number of coins to be replenished to accurately determine the amount of coins stored for change. can be obtained.

As mentioned above, if the number of 10 yen coins or 50 yen coins stored as change in the coin tube 11.12 is greater than the predetermined number N or M, the counters 15 and 16 always indicate the content representing the predetermined number N or M. However, if it is less than N or less than M, the correct number of stored sheets is always specified.

The timers 19 and 20 are provided to prevent the counters 15 and 16 from subtracting the coins paid out at the moment the stored amount reaches N or M coins.

The count contents of the 50 yen counter 16 are added to the 50 yen change storage amount comparison circuit 45.

A comparison circuit 45 outputs a signal 1 to a cash line 46 in which one or more 50 yen coins for change are stored.

If there are no 50 yen coins, the signal on the line 46 is "1o". The counted contents of the 10 yen counter 15 are applied to the 10 yen change storage amount comparison circuit 47.

Comparison circuit 4T outputs signal 1 to output line 48 when four or more 10 yen coins for change are stored, and outputs signal 1 to output line 49 when nine or more coins are stored.

The signals on lines 46 and 48 are applied to an AND circuit 51.

Therefore, the AND circuit 51 outputs the maximum change payout amount when the storage amount of change coins is a combination of one or more 50 yen coins and four or more 10 yen coins, that is, the amount of change coin storage is a combination of 50 yen coins and 10 yen coins. When (90 yen) is satisfied, signal 1 is output.

Further, the signal on line 46 is applied to AND circuit 52 via inverter 53, and the output on line 49 is also applied to AND circuit 52.
join.

Therefore, when there is no 50 yen coin for change, the AND circuit 52 calculates the maximum change payout amount (
The outputs of the 3-AND circuits 51 and 52, which output signal 1 when the condition (90 yen) is satisfied, are applied to the OR circuit 54.

Therefore, the OR circuit 54 outputs a signal 1 when the change coin storage amount satisfies the maximum change payout amount by a combination of one or more denominations.

The output of the OR circuit 54 is applied to the comparison circuit 4 and also to the comparison circuit 5 via the inverter 6.

The comparison circuit 4 outputs a signal 1 when the input amount K is larger than the set selling price SP (K≧SP), and outputs a signal 0 otherwise, and when the output power of the OR circuit 54 is 1" Perform a comparison operation.

The comparator circuit 5 outputs a signal 1 when K=SP, and outputs a signal 0 otherwise, and operates when the output of the OR circuit 54 is η0''.

Therefore, when coins equivalent to the maximum change payout amount are stored, the comparison circuit 4 operates, and the input amount K is changed to the selling price S.
If it is the same as or thicker than P, a sales permission signal VEND is outputted via the OR circuit 7.

In addition, if coins equivalent to the maximum change payout amount are not stored, the comparison circuit 5 operates, and only when the input amount and the selling price SP match (that is, when there is no need for change), the sales permission signal VEND is activated. Output.

A signal for the set selling price SP is supplied from the selling price setting circuit 3.

The input amount includes the switch 35.36 that detected the input coin.
37 is applied to the pulse converter 1 to form a pulse signal corresponding to the amount of money, and this is obtained by adding and counting the pulse signal in the main counter 2.

A sales authorization signal VENα is also applied to the vendor section (not shown) to enable the vendor section to perform a dispensing operation for the item selected by the purchaser.

Note that this invention can be applied to a vending machine that can sell multiple products at the same time.

; In this case, the amount of money inserted will be large and the amount of change paid will also be large (100 yen or more), but the 100 yen coins used for change will be temporarily held, and the amount of 100 yen or more will be temporarily reserved. If there is change, I temporarily put it on hold1.
You only need to pay out 00 yen coins, so there is no need to consider the lack of change in the 100 yen range.

Therefore, in this case as well, it is only necessary to consider the lack of change in the 10 yen range, and the determination can be made by assuming that the maximum amount of change is essentially 90 yen.

That is, for example, even when actually dispensing 180 yen as change, the comparison circuit 45, 47 AND circuits 51, 52, etc. configured with the maximum change payout amount as 90 yen is used to determine the amount of coins stored for change, and the amount of change coins stored is determined. Determine whether it is possible.

If you have a combination of 50 yen and 10 yen coins with a storage amount of 90 yen or more, you can pay out 80 yen in change and the remaining 100 yen coins.
Yen pays out one 100 yen coin that was on hold at 1 o'clock.

As explained above, according to the present invention, the possibility of dispensing change is determined based on a combination of coins of multiple denominations stored for change, so there is a shortage of change compared to when only one type of coin is used. This makes it less likely that sales will be prohibited due to restrictions, and the sales efficiency of the vending machine can be improved.
