Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a control device for a vending machine that requires driving a plurality of power units in a predetermined time relationship when selling one product.

<Conventional technology> In a vending machine that dispenses containers, materials, hot water, etc. sequentially at a predetermined time interval and mixes products for each sale, product components (containers, various materials,
It is equipped with a plurality of power units corresponding to each type of water (hot water, etc.), and by driving and controlling these power units at predetermined timings, each product component is discharged at a predetermined time relationship (for example, 1978
−77399). In the conventional control device for this type of vending machine, the operation timing of each power section is fixed. That is, since the discharge timing of each material of each product component varies depending on the product type or the type of vending machine, it has conventionally been necessary to prepare a dedicated control device for each type of vending machine. For example, in vending machines that mix and sell coffee, the diameter and discharge speed of the material discharge nozzle may differ depending on the model, and even when blending coffee with the same taste, the discharge time of each ingredient varies depending on the model. It comes in different ways.

<Problems to be Solved by the Invention> Therefore, a dedicated control device must be prepared for each model so that each power section can be operated at a unique timing depending on the model. Since a dedicated control device must be prepared for each model, the productivity of the control device does not increase and becomes an obstacle in reducing manufacturing costs. Additionally, for vending machine owners, if they wish to change the items sold in their existing vending machine or change the material blending ratio, they must replace the entire control device, which is a sterile drug and cannot be changed. It was making it difficult.

This invention was made in view of the above points,
In vending machines that drive multiple power units in a complex manner, the technical challenge is to enable the use of a common control device among models selling different items, etc., and it can be applied to any model. The aim is to provide a general-purpose control device that can

<Means for Solving the Problems> The control device for a vending machine according to the present invention independently controls the rise time from a predetermined reference point in vending operation to the point in time when the power section starts operating, for each power section. a rise time setting means for setting a fall time from the reference time or the operation start time to a time when the power unit finishes its operation for each power unit independently; A plurality of power units corresponding to each power unit supplying a drive signal to each power unit from the rise time set by the rise time setting unit to the fall time set by the fall time setting unit. variable timer means, a plurality of product selection switches, timer selection setting means for setting, for each product selection switch, a combination of the variable timer means to be used for selling the product corresponding to the switch, and the product selection switch. and control means for effectively operating only a specific combination of the variable timer means set by the timer selection setting means in response to the operated switch in accordance with the operation of the selection switch. It is.

The configuration of this invention is illustrated in a functional block diagram as shown in FIG. 6. Further, to show the correspondence between the embodiments of the present invention described later with reference to the attached drawings and the configuration of the present invention described above, the variable timer means is the variable timer circuit 153, and the rise time setting means is the timer rise time setting section. 155 The fall time setting means is a timer fall time setting section 156, the timer selection setting means is a timer selection setting section 159, and the control means is a circuit portion related to input/output to the timer selection setting section 159 in the sales control section 150. , respectively.

<Function> Depending on the model of the vending machine or the type of product to be sold, the operating time of the variable timer means corresponding to each power section can be arbitrarily programmed in advance using the rise time setting means and the fall time setting means. I'll keep it. Of course, this program can be changed freely. Further, depending on the characteristics of each product, the combination of variable timer means to be used for selling the product is set in advance by the timer selection and setting means. This setting can also be changed. In this manner, after the desired settings are made in advance by the rise time setting means, the fall time setting means, and the timer selection setting means, the vending machine is put into operation.

When a certain product is selected, the control means controls only the specific combination of variable timer means set corresponding to the selected product by the timer selection setting means, depending on the selection of this product. control to operate effectively. As a result, only a specific combination of variable timer means preset corresponding to each product by the timer selection setting means can operate effectively in accordance with the selection of the product. Each variable timer means in the combination of enabled variable timer means operates and produces an output according to the operating time programmed by the rise time setting means and the fall time setting means. The output of this specific variable timer means is given to the corresponding power section, respectively. In this way, the power units corresponding to the combinations set by the timer selection setting means operate at operating times according to the selected product and according to the program of the rise and fall time setting means, and their cooperation The specific product selected will be provided by the service.

<Embodiment> Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

In FIG. 1, the coin control unit 10 mainly includes:
Count the amount of coins (or banknotes) inserted and compare them with the selling price to determine whether they can be sold, and then pay out change after subtracting the selling price of the sold product from the inserted amount. This is the part that performs control. The coin detector 151 inspects the authenticity of the inserted coin (or banknote) and generates coin detection signals CD1 to CD3 corresponding to the denomination of the genuine coin. When the change dispensing mechanism 152 receives the change dispensing signals PO ₁₀ , PO ₅ , PO ₁ from the coin control unit 10, it dispenses a coin corresponding to the denomination as change.

The sales control unit 150 includes a variable timer circuit 153, and the variable timer circuit 153 includes m power units 154-1 to 154-m on the bender mechanism side.
Contains variable timers T ₁ to Tm corresponding to .
The power units 154-1 to 154-m contain m types of product components (cups, undiluted solution, sugar, milk, hot water, etc.)
corresponds to each individual. When the timer outputs T ₁ O to TmO are given from the variable timer circuit 153, the drive units (154-1 to 154-
m) is driven, and the product component corresponding to the driven power section is discharged. Power part 15
4-1 to 154-m are constituted by solenoids, pumps, motors, etc., depending on the properties of the corresponding product components. Note that each of the power units 154-1 to 154-m does not necessarily have to correspond one-to-one to each product component, and one product component can be discharged by combining multiple power units. You can leave it there. The timer rise time setting unit 155 is a means for arbitrarily setting the rise time of each timer T ₁ to Tm. The timer fall time setting unit 156 is a means for arbitrarily setting the fall time of each timer T ₁ to Tm. Each timer T ₁ is set according to the rise time and fall time set by these setting sections 155 and 156.
~ The operating time of Tm is determined respectively.

The sales control unit 150 also controls product selection switches 157-1 to 157-n corresponding to n types of products.
The outputs S ₁ to Sn are received from the vendor mechanism side, and if a plurality of product selection signals S ₁ to Sn are generated, one of them is selected and stored. The stored product selection signals S ₁ ′ to Sn′ are added to the readout address input of the sales price setting section 158 and the timer selection setting section 159 . In the sales price setting section 158, the sales price (SP ₁ to SPn) corresponding to each product is set by a diode matrix or the like, and is applied to a single product selection signal S ₁ ' to Sn' added to the readout address input. The corresponding sales price SPi (i is any one from 1 to n) is read out. The timer selection setting section 159 selects a timer for each product to be used for selling that product.

The extra switch group 160 provided on the vendor mechanism side is a switch for increasing or decreasing the amount of product components (undiluted solution, sugar, milk, etc.) according to the purchaser's preference, and the output thereof is sent to an increase/decrease encoder 161. is input. The increase/decrease encoder 161 outputs data representing an increase or decrease in the amount of a predetermined product component in response to the operation of the switch group 160. The output data of the increase/decrease encoder 161 acts to change the timer fall time in the variable timer circuit 153, and as a result, the timer operating time of a predetermined product component is increased/decreased, and its discharge amount is increased/decreased. The amount display 162 is for displaying the input amount (or remaining amount) counted by the coin control unit 10,

In the coin control unit 10 shown in FIG. 2, the coin detection signal CD1 given from the coin detector 151
~CD3 is added to the pulse generator 163 and generates coin pulses C ₁₀ , C ₅ ,
C ₁ is generated from the pulse generator 163. Coin pulses C ₁₀ , C ₅ , C ₁ are, for example, 100 yen, 50 yen,
Corresponds to 10 yen respectively, OR circuit 18, 19,
20, it is input to addition/subtraction counters 21, 22, and 23 corresponding to each denomination (100 yen, 50 yen, 10 yen). Addition/subtraction counters 21, 22, 23
The output of the OR circuit 24 that is applied to the subtraction control input is initially "0", and when it is "0", addition is performed, and "1"
When , subtraction is instructed. Therefore, the curing pulse
Each counter 21, 2 based on C ₁₀ , C ₅ , C ₁
In steps 2 and 23, the input amount for each denomination is added and counted.
In order to be able to use banknotes (for example, 1000 yen), it is sufficient to use a coin detector 151 capable of detecting banknotes and to add a counter for banknotes.

The counting outputs of the counters 21, 22, and 23 are added to an adding circuit 25, and the adding circuit 25 obtains the total amount of input (or remaining amount). A signal representing the input amount (or remaining amount) K outputted from the addition circuit 25 is applied to the comparison circuit 26 and also to the amount display 162, so that the input amount or remaining amount is displayed. Note that the adder circuit 25 generates an all-zero signal R ₀ (sets it to "1") when the total amount is 0. The all-zero signal R ₀ is supplied as a reset signal to each circuit within the coin control section 10 and is also supplied to the sales control section 150 via the line 13.
Moreover, the all-zero signal R ₀ is connected to the coupler 164 (the first
) to the product selection switches 157-1 to 157-n on the vendor mechanism side. coupler 16

4-m, 185-1 to 185-m are in the reading mode when the all zero signal _R0 is "1", that is, in the standby state (the state in which the hard material is not inserted), and the timer rise time setting section 155 and the timer fall Setting data of rise times TR ₁ -TRm and fall times TD ₁ -TDm of each timer T ₁ -Tm set by the time setting section 156 is stored. When a coin is inserted and the all-zero signal _R0 becomes "0", the memory circuits 184-1 to 185-m enter the read mode, and the stored data _TR1 to TRm,
Read TD ₁ to TDm. The setting section 155 includes switch groups 155-1 to 155-m for arbitrarily setting the rise times TR ₁ to TRm of each timer T ₁ to Tm, and the setting section 156 similarly sets the fall times TD ₁ of each timer. ~Switch group 1 for arbitrarily setting TDm

After inserting a coin, press the desired product selection switch 1
When 57-1 to 157-n are selected, product selection signals _S1 to Sn are supplied to sales control section 150. In the sales control unit 150 shown in FIG. 3, the product selection signals S ₁ to Sn are supplied to AND circuits 165-1 to 165-n and OR circuits 164-1 to 166-n.
The data are stored in SD flip-flops 168-1 to 168-n via SD flip-flops 168-1 to 168-n. AND circuits 165-1 to 165-n are
This is for storing only a single product selection signal S ₁ to Sn in the SD flip-flops 168-1 to 168-n, and the time division timing pulses Ta ₁ to Tan
and SD flip-flops 168-1 to 168
After all outputs of -n are combined by an OR circuit 169, a signal inverted by an inverter 170 is input. SD
The flip-flops 168-1 to 168-n are
It is driven by a predetermined clock pulse and outputs the input signal after being delayed by one bit time (one cycle of the clock pulse). The time-division timing pulses Ta ₁ to Tan are pulses that are generated sequentially in each cycle of the above clock pulse, and in the first cycle,
The pulse Ta ₁ is generated in the order of Ta ₂ in the next cycle, and the pulse Tan is generated in the nth cycle. Therefore, each pulse Ta ₁ -Tan is generated repeatedly every n periods of the clock pulse.

Incidentally, since the coin control section 10 and the sales control section 150 can be operated asynchronously, the clock pulses used by both may be different. Generally, the coin control section 10 uses a high-speed clock pulse because it is necessary to perform a high-speed counting operation, but the clock pulse of the vending control section 150 may be at a low speed (for example, in milliseconds).

AND circuits 165-1 to 165-n are pulse
Since it can be operated in a time-sharing manner by Ta ₁ to Tan, the product selection switches 157-1 to 157-n
are pressed simultaneously and multiple product selection signals S ₁ ~
Even if Sn is supplied simultaneously, only one signal S ₁ -Sn is selected in a certain time division time slot. For example, if the signals _S1 and Sn rise at the timing of the pulse Ta1, only the signal _S1 is selected by the AND circuit 165-1, and the signal Sn is blocked by the AND circuit 165-n. Next, when the SD flip-flop 168-1 that has read the signal _S1 outputs " ₁ " at the next timing of the pulse Ta1, the output of the OR circuit 169 becomes "1" and the output of the inverter 170 becomes "0". Falling, AND circuit 16
5-1 to 165-n are all rendered inoperable. Therefore, even if the timing of the pulse Tan arrives, the signal Sn is blocked by the AND circuit 165-n. In this way, a single product selection signal _S1 is selected. The output of the SD flip-flop 168-1, which has read the selected signal _S1 , is sent to the AND circuit 171-1.
will be returned to. A product selection signal _S1 is input to the other input of the AND circuit 171-1, and its output is returned to the SD flip-flop 168-1 via OR circuits 166-1 and 167-1. Therefore, only the single selected product selection signal S ₁

It is held at 1.

In the sales price setting section 158, data indicating the sales prices SP ₁ to SPn corresponding to each product is set by a diode matrix, and corresponds to the input single product selection signal S ₁ ′ to Sn′. Then, the selling price SPi (any one of SPi to SPn) of the product is read out. The data indicating the read sales price SPi is sent to the comparison circuit 2 of the coin control unit 10 via the line 14.
6 (Figure 2). Although the line 14 is a line of multiple bits, it is shown as a single line in FIG. 2 for convenience. Similarly, the timer selection setting section 159
A combination of timers corresponding to each product is set by a diode matrix, and the timers _T1 to Tm used for selling that product are set in response to a single input product selection signal _S1 ' to Sn'. timer selection signal
T ₁ S to TmS are read. For example, if the timers used to sell a certain product are T ₁ , T ₂ , T ₅ , T ₇ , the timer selection signals T ₁ S,
T ₂ S, T ₅ S, and T ₇ S are read simultaneously.

In the comparison rotation circuit 26 shown in FIG.
The selling price SPi given from 4 is compared with the input amount (or remaining amount) K given from the adding circuit 25, and when the sale is possible, an OK signal is output. In detail, the change out signal from the change payout control circuit 30

≧SPi”, outputs “1” (OK signal). When there are no coins in the change (or return) coin storage device (not shown) or the number of coins is less than a predetermined number, an out-of-change signal is generated based on the out-of-change detection signal NC' from the change dispensing mechanism 152 (FIG. 1). N.C.

The OK signal output from the comparator circuit 26 is applied to the sales control section 150 via the line 15, and is sent via the OR circuit 172 to the SD flip-flop 173.
is loaded into. The signal "1" read into the SD flip-flop 173 is self-held via an AND circuit 174 and an OR circuit 172. The output of the OR circuit 169 and the output of the NAND circuit 175 are applied to other inputs of the AND circuit 174. The output “1” of the OR circuit 169 is a single product selection signal.
This indicates that S ₁ ' to Sn' are stored in the SD flip-flops 168-1 to 168-n.
The output of the NAND circuit 175 is normally "1",
When the OK signal once rises to "1" and then falls to "0", it becomes "0". Such a change in the OK signal from "1" to "0" may occur when the user is out of change. When the coin is out of change, if "K=SPi" is established in the comparison circuit 26 during the coin insertion process, an OK signal is generated and "1" is stored in the flip-flop 173. When additional curing is added, "K>SPi" is established, and "1" is not output from the comparator circuit 26 when the change is out.
Therefore, the OK signal falls to "0". nand circuit 1
75 has the output of SD flip-flop 173 and OK
A signal obtained by inverting the signal by an inverter 176 is added, and when the OK signal changes from "1" to "0", the condition of the NAND circuit 175 is satisfied, its output becomes "0", and the SD flip-flop 17
3's self-hold is released. That is, even if the SD flip-flop 173 is once set to a state in which it can be sold, it is immediately reset when it is later determined that it cannot be sold.

The output of SD flip-flop 173 is timer 1
77, and the output of the timer 177 is input to AND circuits 178-1 to 178-n. The other inputs of the AND circuits 178-1 to 178-n are SD flip-flops 168- to 168-n.
and the all reset signal AR to inverter 1.
The inverted signal is added at 79, and its output is returned to SD flip-flops 168-1 to 168-n via OR circuits 167-1 to 167-n. The output of inverter 179 is normally "1". Therefore, when the OK signal indicating that the product is available for sale is stored in the SD flip-flop 173, the SD flip-flops 168-1 to 168-n enter a self-holding state, and the storage of the single product selection signals _S1 ' to Sn' is fixed. be done.

The output of the timer 177 is supplied to the line 16 as the sales start signal VS, and also to the AND circuit 180.
-1 to 180-m. AND circuit 180
The other inputs from -1 to 180-m are timer selection signals T ₁ S read out from the timer selection setting section 159.
~TmS is added, and its output is sent to the memory circuit 181-
1 to 181-m. Therefore, when the sales start signal VS is output from the timer 177, the AND circuits 180-1 to 180-m become conductive, and the timer selection signals _T1S to TmS are stored in the storage circuits 181-1 to 181-m. .

Signal VS on line 16 is applied to the read control input of timer 70 and register 71 of coin control section 10 (FIG. 2). Data indicating the selling price SPi read out from the selling price setting unit 158 is inputted to the data input of the register 71 via the line 14, and this data is input to the register 71 based on the signal VS from the line 16. be remembered. The signal VS on line 16 is also input to a group of extra switches 160 (FIG. 1) on the bender mechanism side, allowing the switches to select an increase or decrease. When a certain switch in the extra switch group 160 is pressed, the increase/decrease encoder 161 outputs increase or decrease data Td ₁ corresponding to predetermined timers T ₁ to Tm.
~Tdm (Fig. 3) is read out corresponding to the press switch. Readout weight gain or weight loss data
Td ₁ to Tdm are the memory circuit 182 of the sales control unit 150
-1 to 182-m. The increase/decrease encoder 161 is composed of, for example, a diode matrix.

The delay time TM ₁ of the timer 177 is, for example, 100ms.
This is set in order to wait until the reading of the sales price setting unit 158 and timer selection setting unit 159 becomes stable. The readout outputs SPi and TiS to TmS, which are reliably stable, are output to the register 71 and the memory circuit 1 based on the output signal of the timer 177.
81-1 to 181-m. The sales price setting unit 158 and the timer selection setting unit 159 are located outside the board (or outside the chip) of the sales price setting unit 150.
Since these setting sections 158 and 159 are read out by the signals _S1 ' to Sn' outputted from the sales control section 150 and the readout output is sent back to the sales control section 150 ( Alternatively, when the signal is returned to the board (or chip) of the coin control unit 10), noise may be added to the rising edge of the signal, making reading unstable. The timer 177 was provided in consideration of this point.

The sale start signal VS applied to the coin control section 10 via the line 16 is further delayed by the timer 70. The output of the timer 70 is applied to the read control input of the register 71 and is also applied to the collection control circuit 73 to enter the collection mode. Register 71 is line 1
The sales price SPi data read based on the signal VS from 6 is read out based on the output of timer 70 and inputted to collection control circuit 73. When the money collection control circuit 73 receives a signal "1" from the timer 70 via the line 74, the money collection control circuit 73 calculates the input amount from the register 7 based on the contents of the counters 21 to 23 where the input amount is calculated.
Subtract the selling price value SPi stored in 1.
At this time, the amount corresponding to the sales price SPi is converted into fixed denomination coins and subtracted using the count values for each denomination held in each of the counters 21 to 23. That is, the count value K ₁₀ of the 10 yen counter 23 of the lowest denomination is compared with the selling price SPi given from the register 71, and if K ₁₀ ≧SPi is obtained,
Give "1" to the OR circuit 24 via the line 75, set the counter 23 to the subtraction mode, give a pulse equal to SPi to the 10 yen line _L1 , and add the pulse of the line _L1 from the OR circuit 20 to the counter 23. , the counter 23 subtracts the sales price SPi. If K ₁₀ <SP, the counted value of the 50 yen counter 22 is transferred to the 10 yen counter 23. That is, 50 yen is subtracted from the input amount in the 50 yen counter 22, and the 10 yen counter 23 is added by that amount, and this is repeated until K ₁₀ ≧SPi. If the 50 yen counter 22 cannot fully subtract, the counted value of the 100 yen counter 21 is transferred to the 10 yen counter 23. As a result of transferring the input amount of 100 yen or 50 yen to 10 yen, if K ₁₀ ≧SPi is established, the selling price SPi will be transferred from the counter 23 as described above.
Subtract. In this way, the remaining amount remains on the counters 21 to 23 of higher denominations, and it is possible to pay out higher value coins as change when paying out change. In other words, many low denomination coins, which are often used as change, are accepted, making it less likely that the coin will run out of change.

On the other hand, the output of timer 70 is a timer start signal.
Sales control unit 150 via line 17 as ST
and stored in the storage circuit 183. When the timer start signal ST is stored in this storage circuit 183, time counting in the variable timer circuit 153 is started. In addition, the delay time due to timer 70
TM ₂ is, for example, about 300 ms, which takes into consideration the time required to reliably read the sales price SPi data into the register 71.

The variable timer circuit 153 includes a counter 186 for counting the rise time, a counter 187 for counting the fall time, and a memory circuit 184-1.
Comparators 188-1 to 188-m compare the rise time setting data TR ₁ to TRm stored in the memory circuits 185-1 to 184-m with the counted value of the counter 186; Falling time setting data TD ₁ to TDm and counter 187

Therefore, as shown in FIG. 4, for example, the output of the comparator 188-1 constituting the timer _T1 is "0" from the time when the timer start signal ST is generated until the rise time _TR1 has elapsed. , thereafter “1”

It is "1" until TD ₁ has elapsed, and after that it is "0".

The outputs of comparators 188-1 to 188-m are supplied to AND circuits 190-1 to 190-m, respectively. Timer selection signals T ₁ S to TmS stored in storage circuits 181-1 to 181-m are applied to other inputs of AND circuits 190-1 to 190-m. The output of each AND circuit 190-1 to 190-m is applied to AND circuits 191-1 to 191-m. The outputs of comparators 189-1 to 189-m are added to other inputs of AND circuits 191-1 to 191-m. Therefore, among the outputs of the comparators 188-1 to 188-m, the timer selection signals _T1S ~
Only those corresponding to the timers T ₁ to Tm in which TmS is occurring are selected by the AND circuits 190-1 to 190-m, and the selected comparators 188-1 to 188-1 are selected by the AND circuits 190-1 to 190-m.
88-m output and comparators 189-1 to 189-
The AND logic of the output of m is obtained by AND circuits 191-1 to 191-m. AND circuit 191-
The outputs from 1 to 191-m are output from AND circuit 195-1.
Timer output T ₁ O to TmO via 195-m
As a power section 154-1 to 154-m (first
Figure). Note that the other inputs of the AND circuits 195-1 to 195-m are supplied with a timer start signal.
The output of the storage circuit 183 that stores ST is added.

Therefore, the timer outputs T ₁ O to TmO are set to "1" when a predetermined timer rise time TR ₁ to TRm has elapsed since the timer start signal ST was generated.
The signal that rises and falls to “0” after a predetermined fall time TD ₁ to TDm has passed is the timer selection signal.
Appears only for timers T ₁ -Tm selected by T ₁ S -TmS (see FIG. 4). Power section 154-1 to 154-m on the bender mechanism side (Fig. 1)
are driven while the corresponding timer outputs T ₁ O to TmO are "1". This results in
Each product component of the selected product is output by the timer.
It is temporally controlled and discharged sequentially by T ₁ O to TmO, and products are prepared.

The adders 192-1 to 192-m calculate the timer fall time setting data _TD1 to TDm stored in the memory circuits 185-1 to 185-m. The increase/decrease data Td ₁ to Tdm are added (or subtracted) to each timer to correct the timer fall time setting data input to the comparators 189-1 to 189-m. In the data Td ₁ to Tdm, a value indicating an increase is given as a positive value, and a value indicating a decrease is given as a negative value. Therefore, when the amount is increased, the fall times TD ₁ to TDm are lengthened, and when the amount is decreased, the fall times TD ₁ to TDm are shortened. The values of data Td ₁ to Tdm corresponding to timers unrelated to the operated extra switch 160 are 0, and the corresponding timer fall time TD ₁
~TDm remains unchanged.

In addition, each memory circuit 181- in the sales control section 150
1 to 181-m, 182-1 to 182-m,
183 and the counters 186 and 187, the all-reset signal AR for resetting the counters 186 and 187 may be generated after the preparation of one product is completed. An example for this purpose is the AND circuit 19
Timer output T ₁ O from 5-1 to 195-m
All TmO is input to an OR circuit 196, and the output of the OR circuit 196 is stored in a storage circuit 198. The output of the memory circuit 198 and the output of the OR circuit 196 are inverted by an inverter 200 and the output thereof is input to the AND circuit 199 and the timer 201 . This allows the timer output T ₁ O to TmO
occurs once and all outputs _T1O to TmO become "0", that is, when the operating time of all timers ends, the AND circuit 199 outputs "1".
is output. A signal obtained by delaying the output "1" of the AND circuit 199 by a predetermined time by a timer 201 is set as an all reset signal AR. Furthermore, timer 20
By setting the delay time of 1 to a certain degree, it is assumed that before the output of a certain timer rises, all the outputs of the timers that started up earlier fall, and the condition of the AND circuit 199 is temporarily satisfied. It is also possible to prevent the timer 201 from generating the all reset signal AR. The all reset signal AR also resets the memory circuit 198, and furthermore,
The product selection signals S ₁ ' to Sn' stored in the SD flip-flops 168-1 to 168-n via the inverter 179 are also reset. When the signals _S1 ' to Sn' are erased, the output of the OR circuit 169 becomes "0",
The self-holding of the SD flip-flop 173 is also released. Note that the method of generating the all-reset signal AR is not limited to that shown in FIG. For example, the output of the memory circuit 183 may be input to a timer set with a long delay time, and the output of this timer may be used as the all-reset signal AR, or when a compounded product is taken out by a purchaser. It is also possible to receive a signal from the vendor mechanism indicating that the cup containing the product has been picked up (for example, a cup-off signal indicating that the cup containing the product has been picked up) and generate the all-reset signal AR based on this signal.

Continuous sales can be made any number of times by repeatedly pressing the product selection switch within the range of the input amount, and the collection control circuit 73 operates to subtract the input amount from the counters 21 to 23 for each sale. To end the purchase, the payment switch 88 is pressed and the payment signal is stored in the storage circuit 89. The settlement signal stored in the memory circuit 89 is applied to a timer 91 via an AND circuit 90. A signal obtained by inverting the output of the timer 70 by an inverter 92 is added to the other input of the AND circuit 90, so that even if the payment switch 88 is pressed while the payment control circuit 73 is operating, the payment state does not immediately occur. It's getting old. The output of the timer 91 is applied to the change payout control circuit 30 as a change payout command. When the change payout control circuit 30 receives a change payout command from the timer 91, it performs control to pay out the remaining amount of each denomination held in the counters 21 to 23 as change according to the denomination (depending on the denomination of the remaining amount). Change payout signal corresponding to PO ₁₀ ,
outputs PO ₅ and PO ₁ ). At the same time, "1" is given to the counters 21 to 23 via the OR circuit 24 to set the subtraction mode, and a pulse corresponding to the amount paid out as change is given to the counters 21 to 23 via the OR circuits 18, 19, and 20. The amount of change paid out is subtracted from the counters 21-23. Thus counter 2
Change is paid out until the contents of 1 to 23 become 0. When the contents of the counters 21-23 become 0, an all-zero signal _R0 is generated and the memory circuit 89 is reset.

The timer 91 is used to set the waiting time _TM6 until the inserted coin is securely stored in the coin storage tube in case the adjustment switch 88 is pressed immediately after the coin is inserted. be.

In addition, in the variable timer circuit 153, a rise time counter 186 and a fall time counter 187 are provided.
may be made common. Further, the counting clock pulses CP ₁ and CP ₂ may be made variable, so that the operating times of the timers T ₁ to Tm can be uniformly changed. Furthermore, the overall configuration of the variable timer circuit 153 is not limited to that shown in _FIG.
~Tm and whose rise time and fall time can be arbitrarily changed. Also,
The configuration may be such that the falling times TD ₁ to TDm are processed as the time from the rising time. Furthermore, the configuration of the sales price setting section 158, timer selection setting section 159, and increase/decrease encoder 161 is not limited to the diode matrix, but may also include a group of switches and a write-readable memory circuit, such as the timer fall time setting section 155. may be configured.

In FIG. 3, the variable timer circuit 1
I am trying to start the timer operation of 53, but
However, the present invention is not limited to this, and it is safer to start the timer operation based on the cup drop confirmation signal. For example, as shown in FIG. 5, the variable timer circuit 153C dedicated to the cup is separated from the variable timer circuits 153 of other product components (materials), and only the variable timer circuit 153C dedicated to the cup is controlled by the timer start signal ST. Let it start. A timer rise time setting switch 155C, a timer fall time setting switch 155D, and memory circuits 184C and 185C are also provided for the cup, and the rise time TRc and fall time set by these are also provided.
A timer output TcO for cup dropping is generated from the variable timer circuit 153C in accordance with TDc. This timer output TcO drives a power section (not shown) for dropping the cup. When the cup falls to a predetermined position, a cup drop confirmation signal CUPON is given from the bender mechanism and stored in the memory circuit 202. The timer start ST stored in the storage circuit 183 and the cup drop confirmation signal CUPON stored in the storage circuit 202 are input to the AND circuit 203. The output of the AND circuit 203 is the variable timer circuit 1
53 and starts time counting in the variable timer circuit 153. Variable timer circuit 153 has the same configuration as in FIG. 3, and the output of AND circuit 203 is added to AND circuits 193 and 194 (FIG. 3). With the above configuration, the timer outputs T ₁ O to TmO are generated after the cup is reliably dropped, and the material is reliably discharged into the cup, so it is safe. Note that the cup drop confirmation signal CUPON occurs not only when a cup is confirmed to have fallen, but also when other conditions (such as whether the hot water has reached a specified temperature or whether there is a shortage of material) are met at the same time. It is a good idea to do so. Also, after the timer start signal ST is generated, a cup drop confirmation signal is generated.
If CUPON is not generated after a predetermined period of time, it is regarded as an abnormality, and an all-reset signal AR is generated and a settlement signal is given to the change payout control circuit 30 (Fig. 2), so that the inserted coins are automatically returned. Good too. In the example shown in FIG. 3, the variable timer circuit for the cup is not separated, so any one of the timer outputs T ₁ O to TmO corresponds to the cup ejecting power section.

Of course, the present invention is not limited to vending machines that prepare food and drinks, but can be applied to general vending machines that drive a plurality of power units in an appropriate combination in a timed manner when dispensing one product.

The relationship between the products selected by the product selection switches 157-1 to 157-n and the power units (i.e., timers T ₁ to Tm) used for selling the products is determined by the settings of the timer selection setting unit 159. It can be easily changed by changing . In addition, the drive time (timing of drive start and end) of each power unit, that is, the operation time of timers T ₁ to Tm, is
It can be easily and freely changed by changing the settings in the timer rise time setting section 155 and the timer rise time setting section 156.

<Effects of the Invention> Therefore, the control device of the present invention has the advantage that it can be applied to any type of vending machine or product item of any characteristic by simply changing the setting mode of each setting means as necessary. It has a great effect.
In addition, circuit parts other than the setting means (coin control unit 1
0 and the vending control unit 150) do not need to be changed at all when used in any type of vending machine, so it is advantageous when integrated circuits are mass produced, and mass production reduces manufacturing costs. be able to. Further, since the functions of the vending machine can be changed simply by changing the setting means, it is possible to change the selling items or the material mixing ratio easily and economically.
