Description

[Detailed description of the invention] The present invention relates to the control &1 of a vending machine.

Conventionally, in vending machines, in order to reliably prevent the situation where change cannot be paid to the purchaser, the change storage amount is set to a predetermined value (this predetermined value is usually If the amount is less than the maximum amount equivalent to change (for example, 90 yen), a ``out of change'' message is displayed, and subsequent sales operations that require change are prohibited. It is composed of The conventional method for detecting "out of change" is to install a coin detection switch (empty switch) at a predetermined position of the change coin storage tube (usually near the position corresponding to the maximum amount of change), and to detect "out of change" based on the output of this switch. It detected that the machine had run out of change.

On the other hand, one of the important issues in improving the sales efficiency of vending machines is to prevent the situation of running out of change as much as possible and to keep the vending machine in a state where it can always operate. . This problem has become particularly important in vending machines that are being developed recently and handle a large amount of money in a single purchase (sales). In other words, in this new type of vending machine, the purchaser's choice is made in a single purchase from the time the purchaser first inserts a coin to the time he or she presses the checkout button (switch). The system is configured so that a plurality of products can be sold continuously, and therefore the selling price tends to be large, and accordingly, the total amount of coins input tends to be large. The amount handled becomes large1
First, there is a high probability that the amount of change paid or the amount returned when canceling the purchase will be large. Therefore, if this point is not taken into account, there is a risk that "out of change" situations will occur frequently.

Therefore, in order to secure enough coins for change, an auxiliary coin storage device (hereinafter referred to as an auxiliary tube) exclusively used for coin dispensing
Recently, methods have been proposed to provide Originally, only a coin storage tube (hereinafter referred to as the main tube), which was designed to automatically replenish coins inserted by the purchaser, was used as a coin storage device for change or dispensing in vending machines. Ta. In addition to this main tube, an auxiliary tube dedicated to coin dispensing, into which coins are manually replenished by the vending machine manager, is provided in order to ensure a sufficient supply of change coins.

By the way, the problem here is a method for detecting "out of change" regarding the main tube and the auxiliary tube, and no effective means regarding this point has yet been proposed. For example, it is possible to provide the aforementioned "empty switches" in each main tube and each auxiliary tube, but this would increase the number of "empty switches" as the number of main tubes and auxiliary tubes increases. This not only increases the cost, but also occupies a large amount of space for mounting the switches due to the large number of switches, resulting in an increase in the size of the coin accepting device of the vending machine, making it unsuitable for practical use. Furthermore, if an encity switch is installed in each coin storage tube as described above, when the amount of stored coins falls below the position of each switch, coin dispensing from each tube will be prohibited. Vending machines that require change with less than a fixed amount of coins left behind will be completely prohibited. The remaining number of coins below the specified amount may amount to a considerable amount (the amount that can be paid out as change) when the main tube and auxiliary tube are combined.
This could lead to an inefficient situation where sales are prohibited even though change can be paid.

Another problem that arises when using an auxiliary tube exclusively for dispensing coins is at what point should the main tube be switched to the auxiliary tube used for actually dispensing coins, or should the auxiliary tube be switched to the main tube? This is a problem in switching control of the current dispensing tube.

As a conventional technique regarding this point, a method has been proposed in which a switch for detecting the switching position is further disposed on the main tube side in addition to the above-mentioned city switch.

When the number of coins stored on the main tube side becomes less than the position of the changeover position detection switch, the switch is turned off and the tube used for dispensing is switched to the auxiliary tip. However, this method has the disadvantage that mounting the switch for detecting the switching position requires space, and also has the disadvantage that the number of switches for detecting the switching position increases as the number of bars, tables, and bars increases.

The present invention has been made to solve the various problems mentioned above, and it is an object of the present invention to provide a control system for a vending machine that can reduce as much as possible the probability that the machine will run out of change.

Another object of the present invention is to further provide the above-mentioned auxiliary tube in addition to the main tube into which inserted coins are automatically replenished, and to install an "encity switch" in each of the main tube and the auxiliary tube.
(However, only one coin is provided in a single main tube for the lowest denomination denomination) and effective "coin out" detection can be performed without providing a special "changeover detection switch" between the main tube and the auxiliary tube. The purpose is to control dispensing tube switching between tubes.

According to the present invention, each main tube of each denomination is provided with a "storage coin counting circuit" that performs addition/subtraction counting in response to the entry and exit of stored coins in and out of the main tube of each denomination of change coins. Then, change coin payout control is performed using the contents of this stored coin counting circuit as a guide. When coins are dispensed for change, in principle, coins are dispensed in combinations of denominations corresponding to the counts held in the input coin counting circuit for each denomination described above. First, if the amount equivalent to the change payout is stored in the raw denomination input coin counting circuit, and the number of coins is 1 or more stored in the medium chain denomination storage coin counting circuit, then the medium chain denomination [50 yen] main Control is performed to dispense small denomination coins from the tube. Here, when the number of coins stored in the medium chain denomination storage coin counting circuit reaches O, control is performed to dispense small denomination coins from the living denomination auxiliary tube. When the stored coins in the auxiliary tubes become empty during dispensing from the auxiliary tubes, storage is performed in the biological denomination storage coin blank storage circuit. The auxiliary tube is empty, i.e. the auxiliary tube is empty.
``Out of coins'' is caused by (4) the coin dispensing motor being rotated once, but (B) the dispensing coin detection switch installed near the coin dispensing opening not being activated (no coins being dispensed). Detected on the condition that there was no such thing). Due to the blank memory of the auxiliary tube that occurred during the payout of the auxiliary tube for biological denominations, the payout chi and -zo are for the lowest denomination (for 10 yen).
The main tube is switched to the main tube, and the amount to be paid out in small denomination coins is controlled to be transferred to the lowest denomination coin and paid out. In the next sale, the auxiliary chip for medium-chain denominations will be blankly stored, so even if the contents of the medium-chain denomination storage coin counting circuit are O, small denominations will be stored from the main tube for raw denominations. Control to dispense coins. Further, the dispensing tube may be switched to the soil tube for raw denominations immediately when the auxiliary tip for medium chain denominations becomes blank.

Even if the stored coin counting circuit holds 0, there may be cases where there are actually stored coins, as will be described later.

Now, if coin dispensing is performed from the main tube while the auxiliary tube for medium-chain denominations is blankly stored, the coin dispensing motor will turn once in the same manner as described above. However, if the coins were not dispensed, it means that the living denomination tube is completely empty, or that there is a problem with the dispensing mechanism and there are actually small denomination coins in the tube, but they are not dispensed. When it detects that the payout tube is for the lowest denomination (1
(for 0 yen) Switch to the main tube. At this time, if the number of coins is still stored in the raw denomination input coin counting circuit (although this counting circuit is decremented each time a small denomination coin is dispensed), the small denomination coin is paid out. The remaining amount due is transferred to the lowest denomination coin and paid out.

The payout tube switching control between the main tube for the lowest denomination and the auxiliary cheep for the lowest denomination is almost the same as that for the above-mentioned living denomination tube, and the control mode can be summarized as follows: (1) (Minimum denomination) When the contents of the stored coin counting circuit are not 0, coins are dispensed from the main tube (for the minimum denomination).

(2) (Minimum denomination) When the content of the stored coin counting circuit is 0, coins are dispensed from the auxiliary tube (for the lowest denomination).

(3) When a blank space in the auxiliary tube is detected (the above-mentioned blank condition is satisfied) while dispensing change from the auxiliary tape, the dispensing tube is returned to the main cheese to complete dispensing change.

(4) When dispensing change next time after the dispensing according to item (3) is completed, if the content of the stored coin counting circuit is 0, dispensing from the auxiliary tube is started again in the same manner as in item (3). This is an operation performed to confirm whether change coins have been replenished into the auxiliary tube after the previous change was dispensed.

In the state of item (3) above, if the amount of coins accommodated in the main tube becomes less than the maximum change dispensing class (90 yen) while dispensing from the lowest denomination tube, the entitlement Detection is made, but change is paid out until the end.

Thereafter, the vending machine does not perform sales requiring change due to the engagement signal. The ennoti of the main tube for this minimum denomination is of the conventional configuration (a microswitch actuator is exposed inside the tube, or a proximity switch method with a coil installed around the tube). ) is detected.

Further, even when there are a plurality of auxiliary tubes of the same denomination, the switching control of the dispensing tubes is performed in a manner similar to that described above. That is, a stored coin blank storage circuit is provided corresponding to each auxiliary tube, and blank storage is performed based on blank detection under the above-mentioned conditions. Then, the main tube is switched to the first auxiliary tube on the condition that the content of the stored coin counting circuit for that denomination becomes O.

When a blank space is detected for the first auxiliary tube, the first auxiliary tube is switched to the main tube, and blank storage is performed. When the content of the stored coin counting circuit becomes 0 in the next sale, the main tube is switched to the second auxiliary tube on the condition that the first auxiliary tube blank memory is stored. Once the blank space has been detected and stored for the second auxiliary tube, a switch is made from the second auxiliary tube to the main tube. Furthermore, in the next sale, the main tube will be switched to the third auxiliary tube on the condition that the first auxiliary tube blank memory, the second auxiliary tube blank memory, and the contents of the stored coin counting circuit are 0. Thereafter, the same arc control is performed no matter how the number of auxiliary tables increases. However, the control is not limited to the above control, and for example, the main tube may be switched to the first auxiliary tube on the condition that the content of the stored coin counting circuit for that denomination becomes 0, and the first auxiliary tube may be switched to the first auxiliary tube. Switching from the first auxiliary tube to the second auxiliary tube is performed on the condition that blank memory regarding the tube is performed. Similarly, the auxiliary tube used for dispensing may be switched to the subsequent auxiliary tube one after another on the condition that the previous auxiliary tube is blankly memorized.

As described above, according to the present invention, the coins are dispensed from the auxiliary tube and finally from the main tube until the coin dispensing motor runs idle (it rotates once but no coins come out). Since the coins in the main tubes other than the main tube for the lowest denomination denomination and the auxiliary chisos can be completely dispensed, stored coins are not wasted.

Further, according to the present invention, it is not necessary to provide each coin storage tube with an empty switch as in the conventional case, and only the main tube for the lowest denomination is provided with an empty switch.
The pond tube detects "out of coins" when the coin dispensing motor idles, so it has a simple structure and is economical.

Furthermore, according to the present invention, since there is no need to provide an ennoti detection switch in the auxiliary tube, it is possible to use a coin storage device such as a cylindrical coin storage device rather than a literally cylindrical coin storage tube as the auxiliary tube. becomes. Therefore, a large amount of spare change coins can be stored in the Hotnoy type storage device as an auxiliary tube.
This makes it difficult to run out of change coins.

Furthermore, in order to detect empty status using a switch as in the past, there is a risk of false detection if the stacking of coins in the tube is disturbed, so the inner diameter of the tube must match the diameter of each coin to be stored. However, according to the present invention, the diameter of the tube has no relation to the detection of strength, so it is possible to stiffen a tube with a rough diameter common to boiled coins.

In addition, since blanks in each tube except for the main tube for the lowest denomination are detected by idle rotation of the coin payout motor, there is no possibility that coins may get caught in the payout slide mechanism etc. driven by the motor. Appropriate measures must be taken in such cases. Therefore, according to the present invention, a timer circuit is provided that operates only during the time required for one rotation of the coin dispensing motor (rotation for dispensing one coin), and when the operating time of this timer ends, the carrier switch of the motor is activated. It detects that a coin is caught in the dispensing mechanism on the condition that it is operating. That is, if the motor rotates normally, the carrier switch is turned off, but if the motor cannot rotate fully due to a coin being caught, the carrier switch is still turned on. In such a case, the present invention is configured to control the motor rotation so that the motor repeats forward and reverse rotation several times to release the coins caught in the dispensing mechanism. For example, a stuck coin can be released by rotating the motor about three times in the order of forward rotation → reverse rotation → forward rotation, or reverse rotation → forward rotation → reverse rotation.

In addition, before the purchaser inserts coins to make a purchase, the only empty switch is used to indicate to the public whether the vending machine has the required amount of change coins stored. It is placed at a predetermined location on the main tube of the seed coin. The coins entering and exiting the main tube corresponding to each denomination are added and subtracted by the stored coin counting circuit.
The above-mentioned display can be performed using the contents of this counting circuit, but since the contents of the counting circuit are cleared when the power to the vending machine is cut off, that is, during a power outage, it is necessary to provide an empty switch as described above. .

Therefore, this coin position detection switch has the property of being a "coin storage amount detection guarantee switch during a power outage". Thus, although the present invention includes multiple main and auxiliary tubes, only one empty switch is required.

The present invention has been described in detail above, and below, one embodiment of the present invention will be described in detail with reference to the drawings. This is a schematic diagram of the flow path. Coins inserted through the coin slot 1 are inspected for genuine/false coins and denominations by the coin detector 2. Based on the inspection results, the coins are sorted out by the mechanism 3 and the counterfeit coins are returned. 100 yen specie coins are distributed to the passage 4, 10 yen specie coins are distributed to the escrow device 5, 10 yen specie coins are distributed to the main tube 6, and 50 yen specie coins are distributed to the main tube 7, respectively. The 10 yen coin tube 6 is automatically replenished with the inserted 10 yen coins, and this tube will be referred to as the "A tube" for convenience. The 50 yen coin tube 7 is automatically replenished with the inserted 50 yen coins, and for convenience, this tube will be referred to as "rBf,-B". The auxiliary tube 8 is for storing 10 yen or 50 yen coins by manual replenishment, and for convenience, it is called "C Cheap".
I will call it. Auxiliary tube (Cf tube 8 is 1

The auxiliary tube 9 is dedicated to 10 yen coins, and the stored coins are replenished by a manual replenishment method. For convenience, this tube 9 will be referred to as a "D tube." A tube 6, B tube 7 and C tube 8
It is assumed that the D tube 9 is pre-installed in the standard type coin receiving device and can be added as an ozone tube. A plurality of optional auxiliary tubes can be provided in addition to the D tube 9 as long as the installation space allows. Further, as mentioned above, the optional auxiliary cheese is not limited to a cylindrical one, but may be a hopper type. In addition, an auxiliary tape (D chain f9) is available as an option.
) can be separated from the main body of the coin receiving device as delimited by a dashed line 10, and when separated, a D-tube detachable memory fritsuno-furutsuno 20, which will be described later, is set.

At a predetermined position of the 10 yen coin main tube (A tube) 6 (for example, at a height of 9 coins), the above-mentioned [coin detection guarantee switch J (A tube noti detection device) 36 in the event of a power outage is provided. has been done. The coin dispensing mechanisms 12 for A'/-, -zo, B tube, Cf, and -zo are driven by a first coin dispensing motor Mol, and as described later, the A tube dispensing sonoid 14
1 is energized, coins are dispensed from the Af eniro in accordance with the rotation of the motor MO+, and when the C tube dispensing renoid 142 is energized, coins are dispensed from the C tube f8. Also, when the motor Mol rotates when both the renoids 141 and 142 are deenergized, B
Coins are dispensed from the tube 7. Moreover, when the second coin dispensing motor MO2 is rotationally driven,
Coins are dispensed from the D tube 9 via the dispensing mechanism 13. A carrier switch 143, which will be described later in connection with the motor MOI, and a carrier switch 195, which will be described later in connection with the motor MO2, are provided, respectively, to ensure one rotation of the motors Mal and MO2 required for dispensing one coin.

Coins dispensed from each of the tubes 6 to 9 are guided to the coin dispensing passage 14, and actuate a dispensing coin detection switch 150 (described later) provided therein.

Most of the circuit parts shown in the figure are related to the "payout cheap switching" control mechanism of the present invention. However, as mentioned above, the two figures are separated for convenience, so there is no clear division, and there is no purpose of clearly dividing them by function.

When the aforementioned coin detector 2 detects the insertion of a 10 yen specie coin, one 10 yen detection pulse PIG is applied to the terminal Tl, and when the insertion of a 50 yen specie coin is detected, one 10 yen detection pulse PIG is applied to the terminal Tl. 50
A yen detection pulse Pro is applied to the terminal T2, and when the insertion of a 100 yen specie coin is detected, one 100 yen detection pulse P is applied.

Nogle signals corresponding to the number of 10 yen, 50 yen, and 100 yen coins (regular coins) added to the terminals T, %T2, and T3 are applied to AND circuits 21, 22, and 23, respectively.

A signal on line 24 (described in detail later) indicating prohibition of coin insertion is applied to the input terminals of the AND circuits 21, 22, and 23 via an inverter 25. The output of the acceptance restriction circuit 43A is sent to the AND circuit 22 as a 50 yen coin acceptance flJII restriction circuit 43B.
The output of the 100 yen coin acceptance restriction circuit 43C is added to the AND circuit 23, and now the output of the line 24 is

Based on this, the number or amount of coins to be inserted is 10 yen or 50 yen.
Count by denomination of yen and 100 yen.

For example, there are three 10 yen coins, one 50 yen coin, and 100 yen coins.
When two yen coins are inserted, the 10 yen coin counter 29
The counter 30 for 30.50 yen coins counts 50. The counter 31 for 100 yen coins counts 200.

Furthermore, the 10 yen detection/zorus PIO from the terminal T1 via the AND circuit 21 and the 50 yen detection/'P pulse pso from the terminal T2 via the AND circuit 22 are each a 10 yen storage amount counter 32.50 yen storage amount counter Added to 33.

The 10 yen storage amount counter 32 and the 50 yen storage amount counter are
While the counters 29, 30, and 31 count the amount of coins inserted and set the count value to O every time a sales operation is completed, 1
Continuously add the number of 0 yen and 50 yen coins inserted, continuously subtract the number of dispensed coins, and calculate the number of coins inserted based on the number of 10 yen and 50 yen coins held at the beginning of use of the vending machine. The difference between the number of coins and the number of coins paid out is accumulated and counted.

These 10 yen storage amount counter 32 and 50 yen storage amount counter 33 are used to detect when the number of 10 yen and 50 yen coins held for change is less than the number sufficient for dispensing change (this is called empty). .

That is, the count value of the counter 32.33 is added to the empty detection circuit 34, and based on the count value of the counter 32.33, the number of 10 yen and 50 yen coins held is 4 10 yen coins and 1 50 yen coin. , or when it is detected that 10 yen is less than 9 pieces, a signal "'1" is applied to the empty processing device 35.

Encity processing device 35 is a display unit that displays an out-of-change display when the signal ``1#'' is applied, and in a state where it displays an out-of-change display, the vending machine operates only when the input amount matches the sales setting amount. Do the following.

In this way, empty change coins are detected based on the count value of the 10 yen storage amount counter 32. is cleared to O, and when the current is turned on again, it becomes impossible to accurately detect the empty change coin.

In order to prevent this, an empty detection device 36 is provided which directly detects the number of coins remaining in the main 10 yen tube in addition to the empty detection by the counters 32 and 33.

The empty detection device 36 is, for example, a coil wound around a predetermined position on the main tape and detects the empty condition from a change in the inductance of the coil, or a limit switch is arranged at a predetermined position on the main chisel and -zo. It consists of a device that detects empty state from the on/off of a limit switch, etc., and when the number of coins held in the main tube becomes less than the minimum number required for dispensing change, a signal "l#" is applied to the AND circuit 37.

The input terminal of the AND circuit 37 is connected to the counter 29.
A signal from a comparator circuit 38 which outputs "1" when the count values of 30.31 are all 0 is added.

Therefore, only when the count values of the counters 29, 30, and 31 are all O, the AND circuit 37 is opened, and the signal "1#" is applied to the enity processing device 35 via the enity detection circuit 34, and the appropriate ennotity processing is performed in the same manner as described above. will be carried out.

Here, the AND circuit 37 applies the signal from the empty detection device 36 to the empty detection circuit 34 only when the counts of the counters 29, 30, 31 are all 0, that is, when the vending machine is in a standby state. The reason why the change is not added while the vending machine is in operation is to eliminate the inconvenience that the empty processing device 36 operates while the vending machine is in operation, for example, while dispensing change and the change is not completely dispensed. be.

Further, when the count values of the counters 29, 30, and 31 are all O, the product is selected, and when the 4f key (not shown) is pressed, the insertion of coins is prohibited.

When the product selection button is pressed, a product selection signal PU is applied to the AND circuit 39 via the terminal T5.

The input terminal of the AND circuit 39 is connected to the counter 29.
A signal from a comparator circuit 38 which outputs a signal "1#" when all the count values of 30.31 are O is added.

Therefore, when the count values of the counters 29, 30, and 31 are all 0, when the product selection bit is pressed, the output of the AND circuit 39 becomes 1#, and this signal ``1'' is sent to the OR circuit 40, the OR circuit 41, and the line 24. It is added to the coin insertion prevention device 42 via.

The coin insertion prevention device 42 prevents the insertion of coins when a signal "1" is applied. For example, a pin protrudes from the coin insertion slot to prevent coin insertion, or even if the coin is inserted, the inserted coin is not a coin. It is configured so that it is not detected by the detector and is returned directly to the return slot.

As described above, when the count value of the counters 29, 30, and 31 is 0'', coins cannot be inserted while the product selection button is pressed.

In addition, if a large number of coins of one type are inserted in a round sale, or if the total amount of coins inserted is large, the number of coins held may become unbalanced and there is a risk of a shortage of change. This is not desirable as it may act like a money changer.

For this reason, each coin (10 yen, 50 yen,
100 yen) and the maximum amount of the total amount of coins inserted are limited.

That is, the outputs of the counters 29, 30, and 31 that count the amount of inserted coins by denomination are sent to the 10 yen coin acceptance restriction circuit 43A, the 50 yen coin acceptance restriction circuit 438, and the upper limit detection unit 43, respectively.
In addition to the 100 yen coin acceptance restriction circuit 43C, the contents of each counter 29, 30, and 31 are restricted (for example, a 10 yen coin is 320 yen, a 50 yen coin is 800 yen, and a 100 yen coin is 7
00 yen), each acceptance restriction circuit 43A, 43B
, 43C, and refuses to accept the input coins for each coin type.

The coin rejection device 42 is activated by the signal "1" sent when the total input amount reaches the set upper limit value K (set as appropriate), and the subsequent acceptance of all input coins is prohibited. It looks like this.

The outputs of the counters 29, 30, and 31, which separately count the amounts of the 10 yen coins, 50 yen coins, and 100 yen coins, are applied to the comparison circuit 44.

On the other hand, the selling price of the product is set by a selling price setting circuit 45, serially processed by a serial register 46, and then added to a comparing circuit 44. The selling price setting circuit 45 is configured to set a signal (binary number) corresponding to the selling price by, for example, turning on a plurality of switches as appropriate, and in a vending machine that sells multiple types of products, the above The sales price setting circuit 45 sets a plurality of sales prices corresponding to each product, and is configured to output only the sales price of the product selected by pressing a product selection button (not shown). I won't go into details.

The comparator circuit 44 compares the counts (W
The total input amount K( which is the sum of RA + R1l + R(
=RA+RB+Ro) and the sales set price RsP from the serialization register 45 are compared.

As a result of this comparison, when the total input amount is equal to the sales set price R8p (K=R8P), the signal "1" is sent to the line 47.
This signal is applied to an AND circuit 49 via an OR circuit 48.

Also, when the total input amount K is larger than the sales set price Rsp (K>RsP), a signal "1" is output to the line 5°,
This signal is applied to the AND circuit 51.

A signal obtained by inverting the output of the engagement detection circuit 34 is applied to the other input terminal of the AND circuit 51. When a coin is held, the signal on the line 50 is sent to the AND circuit 4 via the OR circuit 48 in the same way as the signal on the line 47.
Add to 9.

The other input terminals of the AND circuit 49 are supplied with signals obtained by inverting the signals on the lines 52 and 87 (both of which become 1# when the vending machine is in vending operation, and will be described in detail later). ing.

Therefore, if the vending machine is not in the vending operation, the AND circuit 49 is opened and sends the signal "1" as the vending signal v8 to the pender section (not shown) via the terminal T7.

/''//'/ 2, / /' 7, / 7,' The vendor section starts controlling the delivery of the sales product based on the sales signal VK, and at the same time applies a sales start signal S6 to the terminal T4.

Note that the configuration of the pender section is not directly related to the present invention and will not be described in detail here.〇 Sales start signal Se (signal "1") applied to terminal T4
is applied to the timer 54 via the OR circuit 53. The timer 54 receives a predetermined delay time 1. It is configured such that when the signal ``1'' is applied, the output rises from 0'' to 1'' after time to has elapsed.

The output of this timer 54 is applied to an AND circuit 55.

Since the sales start signal S from the terminal T4 is applied to the other input terminal of the AND circuit 55, if the sales start signal S applied to the terminal T4 is held longer than the delay time to of the timer 54, the AND circuit 55 The AND condition is satisfied, and the signal ``'1#'' is transferred to the flip-flop 56 for holding the sales start signal.
In addition, the flip-flop 56 for holding the sales start signal is set, and at the same time, the signal "l" is applied to the delay flag 58 via the OR circuit 57, the delay flip-flop 58 is set, and the set output "1" is set. OR circuit 5 again

The outputs of the seven ring 56 for holding the sales start signal, the output of the delay flip-flop 58, and the output of the timer 54 are applied to an AND circuit 59.

The AND circuit 59 applies the signal °1'' to the AND circuit 60 when the outputs of the flip-flops 56 and 58 and the delay operation of the timer 54 are completed, that is, when the sales start signal Se is confirmed, the AND condition is established.

A product selection signal PU (signal "1") indicating suppression of the product selection button is applied to the other input terminal of the AND circuit 60 via the terminal T5.

Therefore, the AND circuit 60 is opened when the sales start signal S0 is confirmed, and the signal "1#" is sent to the product selection memory 61.
In addition to 〇, the product selection memory 61 receives a signal indicating the product for sale from the serialization register 45 via a line 62, and stores which product has been selected.

By the way, the 7 lip flop f5 for holding the sales start signal
Even after a predetermined period of time (time required for sending out the product) has elapsed after the sales start signal S is set, the signal "1" indicating that the desired product has been selected is stored in the product selection memory 61. If not, this means that one of them has malfunctioned. Therefore, at this time, the operation of the vending machine is stopped.

This operation is performed as follows. The set output ``'1#'' of the flip-flora 7'54 for holding the sales start signal is applied to the timer 63.The timer 63 has the same structure as the timer 54, and the delay time t1 (the normal delivery operation of the product is completed) is applied to the timer 63. When the signal "1" is applied, the signal rises to "1n" after time t1 has elapsed.

The output of this timer 63 is applied to an AND circuit 64.

A signal obtained by inverting the output of the quadruple selection memory 61 is applied to the other input terminal of the AND circuit 64.

Therefore, after the delay operation of the timer 63 is completed, the product selection memo IJ
If the signal ``'1#'' is not stored in 61, the AND circuit 64
The AND condition is satisfied, and the signal '1# is added to the stop circuit 65, stopping the operation of the vending machine and turning off the signal °1''.

(signal "1") is applied to the AND circuit 66 via the terminal T6.

The sales start signal S from the terminal T4 and the output signal of the sales start flip-flop 56 are applied to other input terminals of the AND circuit 66 via an OR circuit 67.

Therefore, the AND circuit 66 sends the sales start signal S8 to the terminal T4.

The output of the product sending signal holding flip-flop 68, the output of the AND circuit 59, and the output of the product selection memory 61 are applied to an AND circuit 69.

In the AND circuit 69, the frizzo 7ozzo 68 for holding the product sending signal is set, and the output of the cyan AND circuit 59 is "1".
When 1# is stored in the product selection memory 61, the sales operation is started simply by inserting a proper coin, the product selection is securely performed, and the delivery of the product is completed. The AND condition is satisfied and the signal "1" is output.The output signal "1#" of the AND circuit 69 is applied to the sales storage flip-flop f70 and set.

Further, this output signal "1" is applied to the money collection command circuit 7e to start a money collection operation (described in detail later), and is also applied to the AND circuit 72 and the AND circuit 73.

When the settlement button (not shown) is pressed, the settlement signal MN is applied to the other input terminal of the AND circuit 73 via the terminal T8, and the flip-flop 7 for holding the settlement signal is set.
The signal from 4 is applied to the other input terminal of the AND circuit 72.
The signal from is inverted and added.

Therefore, when the output of the AND circuit 69 becomes 1'', the 7-bit 70 for holding the settlement signal is activated by pressing the settlement button.
If the flag 74 is set, the AND condition of the AND circuit 73 is satisfied, and the signal "1#" is applied to the change payout command circuit 75 via the OR circuit 740, instructing a change payout operation (described in detail later). In addition, when the output of the AND circuit 69 becomes 61#, if the settlement button is not pressed and the settlement signal holding flip-flop 74 is not set, the AND circuit 69
2 is satisfied, the signal "1" is sent to the product selection memory 61, the product sending signal holding flip-flop 68, the sales start signal holding flip-flop 56, and the delay flip-flop 7'58 through the OR circuit 76. In addition to each reset terminal, these are reset to prepare for the next sales operation in continuous sales.

By the way, the sales start signal holding frig-flo 7″56
, when the product sending signal °So is not applied to the terminal T6 and the product sending signal holding flip-flop 68 is not set even though the delay flip-flop 58 has been set. teeth,
Since the product was not sent, if the payment button was pressed, a refund or change would be made, and if the payment button was not pressed, the product selection memory 6 would be processed.
1. Flip-flops 56, 58, 70, and 74 must be reset to prepare for the next vending operation. This case will be explained. Let us assume that the settlement button is pressed and the settlement signal holding flip-flop 74 is set.

The output of the flip-flop 74 for holding the settlement signal, the output of the timer 63, the output of the AND circuit 59, and the output of the product selection memory 61 are applied to an AND circuit 77.

In the 771 circuit 77, the sales start signal holding flip-flop 56 and the delay flip-flop 58 are set, the AND condition of the AND circuit 59 is satisfied, "1#" is stored in the product selection memory 61, and the timer 63 is set. When the delay operation is completed, the AND condition is satisfied and the signal 11# is applied to the AND circuit 79 and the AND circuit 80 via the OR circuit 78.

The AND circuit 80 includes the sales memory flip-flop 7.
An output of 0 is added to the AND circuit 79, and an inverted output of the sales memory 7 lip 70 is added to the AND circuit 79.

By the way, the sales memory fritsuno flop 70 is set when a sales operation is performed even once, and is reset when the payment button is pressed and the payment operation (change payout, refund) is completely completed. , - times, the sales memory flip-flop 7o is not set, the AND condition of the AND circuit 79 is satisfied, and the signal "1" is applied to the refund command circuit 81.
A return operation (described in detail later) is started to return the entire amount of the inserted coins.

In addition, a sales operation is performed at least once, and 7 RipFlots for sales memory! If 7o is set, the AND condition of the AND circuit 80 is satisfied.

Therefore, a signal "1" is applied to the change dispensing command circuit 75 via the OR circuit 74, and dispensing of change is started.

Next, it is assumed that the payment button is not pressed and the 7-linopflop 74 for holding the payment signal is not set.

Output of flip-flop 74 for holding settlement signal and terminal T4
The signal from is applied to a NOR circuit 82.

The NOR circuit 82 is a flip-flop 74 for holding the settlement signal.
is not set and the signal from terminal T4 is “0”.
” (when the sales start signal S8 is not applied), the signal 11# is applied to the AND circuit 83.

The output of the timer 63, the output of the AND circuit 59, and the output of the product selection memory 61 are added to other input terminals of the AND circuit 83.

Therefore, the sales start signal is confirmed and the product selection memory 61
Even though the signal "1" was stored in the timer 63, the product transport signal was not added until the delay time of the timer 63 expired, and the AND condition of the AND circuit 69 was not established, and the memory 61, flip-flops 56, 58, . 74 is not reset, the AND condition of the AND circuit 83 is satisfied, and the signal "l#" is passed through the OR circuit 76 to the memory 61 and the flip-flop 5.
6.58, 74, 70. In addition to the reset terminal of , these are reset and prepared for the next sales operation.

In addition, if the sales conditions are not met, a sales start signal S is sent from terminal T4.
When 8 is not added, when the settlement button is pressed, a refund will be made if no sale has been made, and change will be paid if it has been made.

The signal from the terminal T4 and the output of the flip-flop f56 for holding the sales start signal are applied to the NOR circuit 84. The NOR circuit 84 outputs a signal "1" when the signal from the terminal T4 is "0#" and the sales start signal holding flip-flop f56 is not set, and adds this signal to the AND circuit 85.

Other input terminals of the AND9 circuit 85 are connected to the output of the delay flip-flop 58, the output of the timer 54, and a signal obtained by inverting the output of the product delivery signal holding flip-flop 68.

By the way, when the settlement button is pressed and the settlement signal holding flip-flop 74 is set, this set output is applied to the delay flip-flop f58 via the OR circuit 57, setting this flip-flop 58, and then,
This set output is applied to the timer 54 via the OR circuit 53, causing the timer 54 to operate.

Therefore, if the payment button is pressed and the operation of the timer 54 is terminated, unless the flip-flop 68 for sending out the product is set, the AND condition of the AND circuit 85 is satisfied, and the signal "1#" is passed through the OR circuit 78. The AND circuits 79 and 80 are added to the AND circuits 3Q and 80.As mentioned above, the output of the sales memory flip-flop 70 and the inverted signal are added to the AND circuits 3Q and 79.If the flip-flop 70 is not set, The AND condition of the AND circuit 79 is satisfied, and a signal “1” is applied to the refund command circuit 81.
If the flip-flop 70 is set, the AND condition of the AND circuit 80 is satisfied, and the signal "1" is sent to the OR circuit 74.
It is added to the change command circuit 75 via the change command circuit 75.

By the way, if coins are inserted into the vending machine during the vending operation, this will cause the counts of the cash counters 29, 30, 31 to fluctuate, which is not desirable. For this reason, the sales start signal Se applied to the terminal T4 and the sales start signal holding 7ritsunofrog 56
The output of the Frizzoflo f68 for holding the settlement signal, the output of the Frizzoflo f68 for holding the settlement signal, and the output of the Frizzoflo f68 for holding the product sending signal are added to the coin rejection device 42 via the OR circuit 86, line 87, and OR circuit 41, and the output of the above signal is If at least one of them is 1'', the coin rejection device 42 is operated to prevent coin insertion.

Further, since the collection command circuit 71, the change payout command circuit 75, and the refund command circuit 81 are configured to hold the signal "1" during the collection operation, change payout, and refund, respectively, Circuit 71, change payout command circuit 75, refund command circuit 8
The signal from 1 is applied to the coin rejection device 42 via the OR circuit 88, the OR circuit 40, and the OR circuit 41, and during the collection operation,
Alternatively, during change disbursement or refund operation, the coin rejection device 42 is operated to prevent the insertion of coins.

Next, the collection operation, refund operation, and change dispensing operation will be explained in detail.

Collection operation The collection operation is performed by subtracting the sales set price R8P from the count value of the 10 yen coin counter 29.

Here, if the sales set price Rsp cannot be subtracted from the count value RA of the 10 yen coin counter 29, a transfer is made from the 50 yen coin counter 30 or the 100 yen coin counter 31 to the 10 yen coin counter 29.

When the signal "1" is held in the collection command circuit 71, this signal is applied to the comparator circuit 89 via line 880.

The sales set price R8 from the serialization register 46 and the counted amount RA of the 10 yen coin counter 29 are added to the comparison circuit 89, and the set price RsP and the counted amount RA of the 10 yen coin counter 29 are added. Compare with RA. In this comparison, the count value R of the 10 yen coin counter 29
A is greater than or equal to the set price R8P (RA
≧R8,), the set price Rsp can be subtracted from the counted value RA of the 10 yen coin counter 29, so the set price R11F is subtracted from the counted value RA of the 10 yen coin counter 29. This subtraction is performed as follows.

When RA≧”BP is satisfied, the comparator circuit 89 sends out a signal “1” to the line 90. The signal on the line 90 is applied as a dirt signal to the r-) circuit 91. On the other hand, the gate circuit 91 is connected to the serialization reno star 46. A pulse signal indicating the sales set price R11 from 1 is added.

Therefore, when signal ``1'' is sent to line 90, r-1.
The circuit 91 is opened and the GILLS signal indicating the sales set price Rsp is added to the subtraction command terminal of the 10 yen coin counter 29 via the line 92, and the 10 yen coin counter 29 is set to the subtraction mode, and at the same time, the 4 GILLS signal is sent to the subtraction command terminal of the 10 yen coin counter 29. It is applied to the count input terminal of the 10 yen coin counter 29 via the OR circuit 93 and the OR circuit 26.

Therefore, the count value R of the 10 yen coin counter 29
The sales price R8P is subtracted from A.

However, in the comparison by the comparison circuit 90, when the count value RA of the 10 yen coin counter 29 is smaller than the sales set price RaP (RA<R8P), the 10 yen coin counter 29
The selling price Rap cannot be subtracted from the counted value C. At this time, the counter 30 for 50 yen coins or the counter 31 for 100 yen coins is used.
Transfer part of Re to 10 yen coin counter RA, R
A≧RsP is established, and then the sales set price R8F is subtracted from the count value RA of the 10 yen coin counter 29. This transfer operation is performed as follows.

When the comparison circuit 89 compares, if RA<RBP, a signal "'1" is sent to the line 94.

The signal ``1#'' on the line 94 is applied to the AND circuit 95.The other input terminal of the AND circuit 95 receives a signal "1#" when the count value RB of the 50 yen coin counter 30 is O (R1=0
) The signal from the comparator circuit 96 whose output is "1" is inverted and added.

Therefore, the AND circuit 95 is opened when the count value RB of the 50 yen coin counter 30 is not O, and the AND circuit 95 is opened when the count value RB of the 50 yen coin counter 30 is not O.
Yen → 10 yen transfer command circuit 97.

The 50 yen→10 yen transfer command circuit 97 instructs a transfer calculation to subtract 50 from the count value RB of the 50 yen coin counter 30 and add the count value RA=50 to the 10 yen coin counter 29. That is, the signal 61 from the AND circuit 95
When # is added, one pulse signal is sent to the line 98, and this pulse signal is applied to the subtraction command terminal of the 50 yen coin counter 30, and is also sent to the 50 yen coin counter 30 via the OR circuit 99 and the OR circuit 27. In addition to the count input terminal of , subtract 50 from the count value RB, and at the same time input
N[i! il), 4' pulse is sent, and this pulse t-1
: Added to the addition command terminal of the 10 yen coin counter 29 and also added to the count input terminal of the 10 yen coin counter 29 via the OR circuit 93 and the OR circuit 26, and the counted value RA
Add 50 to .

When the transfer from the 50 yen coin counter 30 to the 10 yen coin counter 29 by the 50 yen → 10 yen transfer command circuit 97 is completed, a signal "l#" is applied to the comparison circuit 89 via the line 101 and the OR circuit 102. , the count value RA of the 10 yen coin counter 29 and the sales set price Rsp are compared again.

In this way, the count value R of the 10 yen coin counter 29
The transfer from the 50 yen coin counter 30 to the 10 yen coin counter is progressed until A becomes RA≧R8P with respect to the sales setting price R8F, but the count value RB of the 50 yen coin counter 3o is 0. Then, the output of the comparator circuit 96 becomes "1#", the AND condition of the SAND circuit 95 no longer holds, and the 50 yen→10 yen transfer command circuit 97 stops operating.

At this time, the money is transferred to the 100 yen coin counter 31.

When the count value of the 50 yen coin counter 30 is O, a signal from the comparison circuit 96 which outputs 1'' is applied to the AND circuit 103.

The other input terminal of the AND circuit 103 is a signal on a line 94 indicating that the count value RA of the 10 yen coin counter 29 is smaller than the set price R,lP, and a signal of the 100 yen coin counter 3.
A signal obtained by inverting the output signal of the comparator circuit 104 which outputs "when the count value Rc of 1 is O" is added.

Therefore, the AND condition of the AND circuit 103 is satisfied when the signal on the line 94 is 61'' and RB=ORc)O,
A signal "1" is applied to the 100 yen → 50 yen transfer command circuit 105, and at the same time to the 100 yen coin acceptance solenoid control section 106, and one 100 yen coin held is accepted.

This 100 yen coin acceptance solenoid control unit 106 is connected to a flip-flop 1 which receives the output of the AND circuit 103 as a set input via an AND circuit 1061 and an OR circuit 1062.
063, a timer T106 which is activated when the flip-flop 1063 is set, a 7rig 70ug 1068 which uses the output of the timer T106 as a set input via AND circuits 1064 and 1065, and an AND circuit 1065.
．． Flip-frog 106 whose input is the output of 1067
It is composed of 3 reset OR circuits 1069 and 910 by the set output of flip roller 7°1068.
Activate the 0 yen coin acceptance solenoid (escrow cash box solenoid) CB and input 100 which was held.
Accepts and controls yen coins.

Incidentally, the output of the flip-flop 1068 is the AND circuit 1
As other inputs of 067, the inverted outputs are added as other inputs of AND circuits 1065 and 1061, and are also added to AND circuit 10610, which has the output of AND circuit 1066 as another input. Also, the output of the flip-flop 7'1063 is inverted and added to the AND circuit 1064 as another input of the AND circuit 1066. Therefore, the signal "'1" from the AND circuit 103 is input to the AND circuit 10610-other inputs. Since the input is "1", it is applied to the flip-flop 1063 via the AND circuit 1061 and the OR circuit 1062, setting the flip-flop 1063, and the set output activates the timer T106, and after the delay time of the timer T106, the AND circuit 1064
is opened, its output "1" sets a fritsuno flop 1068 via an AND circuit 1065, and the 100 yen coin receiving solenoid CB is energized to accept one 100 yen coin. Also, the output of the AND circuit 1065 resets the flip-flop 1063 via the OR circuit 106B, but now the AND circuit 1066 is open and its output 611 is applied to the AND circuit 10610, and this AND circuit]06' For other inputs of 0, Fritsuno flop 10
68 output "1" is added, so open it and the output "'
1″ is flip 70 horn 10 via OR circuit 1062
63 is set again.

The output of the flip-flop 7'1063 opens the AND circuit 1064 after the timer delay time as described above, but during the interval, the flip-flop 1o68 is set, so the AND circuit 1o67 is opened, and its output '1' opens the flip-flop 1068 to +J. *The 100 yen coin acceptance solenoid CB is demagnetized and one acceptance operation is completed.In other words, it is energized for a sufficient time to accept 100 yen coins, and when continuously accepting 100 yen coins, it demagnetizes the 100 yen coin acceptance solenoid CB. It operates after waiting enough time for the next coin to fall into the 100 yen coin receiving solenoid.

The 100 yen → 50 yen transfer command circuit 105 converts the count value Rc of the 100 yen coin counter 31 to the 50 yen coin counter 3.
This transfers 100 to the count value RB of 0. One pulse is sent to the line 107, this pulse signal is applied to the 100 yen coin counter 31 via the OR circuit 28, and 100 is transferred from the count value R6. and simultaneously subtract line 108
2 pulses are sent to the 50 yen coin counter 30 via the OR circuit 99 and the OR circuit 27.
In addition, 100 is added to the count value RB.

When the transfer of 00 yen is completed, a signal ゛1# will be sent to line 109.
is output and this signal is applied to the AND circuit 110.

When one 100 yen coin is received from the escro solenoid 106, the other input terminal of the AND circuit 110 is '1#'.
Therefore, when the acceptance of the 100 yen coin is confirmed, the AND circuit 110 is opened and the signal 6e'' is applied to the comparison circuit 89 via the OR circuit 102, and the signal 6e is applied to the 10 yen coin counter 29 again. Count value and set price Rsp
Make a comparison with By the way, since the count value RB of the 50 yen coin counter 30 is not O this time, the AND condition of the AND circuit 95 is satisfied, and the 50 yen → 10 yen transfer command circuit 9
At step 7, a transfer is made from the 950 yen coin counter 30 to the 10 yen coin counter 29.

In this way, the transfer from the 100 yen coin counter 31 to the 50 yen coin counter 30, and the transfer from the 50 yen coin counter 30 to the 10 yen coin counter 29, takes 10 yen coins.
The count value RA of the yen coin counter 29 is the sales set price Rs.
Iteration continues until RA≧R8F for p.

When RA≧Rsp is satisfied in the comparator circuit 89, the signal “1#” is sent to the line 90, and as described above, the signal “1#” is sent to the line 90.
The sales set price RgP is subtracted from the count value RA of the 0 yen coin counter 29.

Further, the signal "1#" of input 790 is applied to the serialization register 46 and the collection command circuit 71 to reset them and complete the collection operation.

When the money collection operation is completed in this manner, the next sale or payment can be made, even though the -th sales operation has ended.

By the way, as long as the settlement button is not pressed, if the sales conditions are met, it is possible to perform continuous sales as many times as necessary by repeating the above sales and collection operations.

Furthermore, when each sale operation is completed, the output of the OR circuit 86 becomes '0'', the output of the SIO circuit 41 becomes O'', and the operation of the coin insertion blocking device 42 is stopped. Coins can be inserted every time the sales operation ends.

Next, referring to FIG. 4, the refund operation when the signal "1" is stored in the refund command circuit 81 and the change payout operation when the signal "1" is stored in the change command circuit 75 will be explained.

Refund operation If you insert a coin but do not buy anything and the checkout is suppressed, the refund command circuit 81 receives a signal ``'1'' as described above.
” is memorized.

The signal 111#l from the refund command circuit 81 is on the line 111.
