Description

[Detailed description of the invention]

The present invention relates to a so-called cooking type vending machine that cooks food appropriately and sells it each time it is sold. An example of such a vending machine is a vending machine that dilutes and mixes ingredients such as coffee, milk, and sugar with boiling water before selling. However, conventional vending machines of this type have a structure in which a sequence is set up for each vending operation and timing control is performed using a timer or cam, etc., making it difficult to perform complex timing control. It is difficult to adjust the tolerances, making it difficult to make fine adjustments, and it is difficult to respond to the diversification of sales items. The present invention was invented in view of the problems of conventional vending machines, and executes a series of vending operations under the control of a central processing unit CPU according to a program set in a storage device (ROM). It is an object of the present invention to provide a vending machine in which the operating time of each operating means can be freely adjusted by operating a volume regulator. Hereinafter, one embodiment will be described in detail with reference to the accompanying drawings. Among the accompanying drawings, FIG. 1 is a block diagram of a vending machine according to the present invention, and the present invention will first be described in detail with reference to this figure. It should be noted that this embodiment uses a vending machine that can sell three types of drinking water as an example. In the figure, 1A to 1C carry out coffee, tea, and cocoa drinking water according to the instructions of the central processing unit (hereinafter referred to as CPU), respectively, and carry out the beverage raw materials, milk, and sugar, and convert them into boiling water (or cold water). The ice cream is diluted and poured into cups that have been carried out in advance to make sales columns for each item.The hot water tank, cold water tank, ice making device, and its carrying out device (not shown) are shared. 2 is each operating means unique to each column 1 to 1C and each operating means shared by these columns, for example, raw material (
(including beverage raw materials, milk, and sugar) transporters, mixers,
It is a volume regulator that sets the operating time of the cutting motor, ice carrying device (solenoid), cup discharging motor, etc. of the ice making device, and supplies information regarding the operating time of each operating means to the CPU according to instructions from the CPU. The information is stored in a read/write memory device (hereinafter referred to as RAM) by the CPU. 3 is the first operating keyboard for test purposes exclusively for the administrator of the vending machine, i.e., the operator, and by operating this, even without inserting coins or magnetic cards, etc.
It is possible to instruct a predetermined person in the column 1 to 1C to carry out a predetermined amount of drinking water through the CPU, thereby prompting the person to take out the drinking water. 4 is a second operating keyboard exclusively for the user and for sale, and after a predetermined coin or magnetic card is inserted, by operating the key corresponding to the predetermined drinking water on the keyboard, the above column is activated through the CPU. It is possible to instruct one person or one person to carry out an unloading operation. The CPU then uses a read-only storage device (hereinafter referred to as
It operates according to the program set in the RAM (ROM), and when the power is turned on to change the vending machine from not in use to being in use, the above-mentioned RAM is
Once cleared, information related to the operating time of each operating means is read from the volume adjuster 2, and this is stored in the RAM. Then, when the vending machine is in the waiting state for sales,
When the test key switch for selecting Areka's product on the first operating keyboard 3 is operated, the operating means of the corresponding column and the operating means common to each column are activated by the program in the ROM and the operating means common to each column. Each operating means is operated in sequence according to the operating time stored in the RAM, and desired drinking water is carried out and poured into a cup. Incidentally, in order to obtain the desired beverage by operating the second operation keyboard 4, the CPU will not output a sales command to the corresponding column unless a predetermined coin is inserted as described above. Therefore, after inserting a predetermined coin, when the sales key switch for selecting any product on the second operating keyboard 4 is operated, the CPU responds in the same manner as when operating the first operating keyboard. The column is driven to transport the desired drinking water. In addition to the commercial amount selection key switch, the first and second operation keyboards have a correction key switch for correcting the operation time of the milk or sugar delivery motor, for example, for milk or sugar increase. , by operating this, C
The PU sets the operating time of these raw material unloaders to the time set by the volume adjuster 2 plus the correction time, and operates the raw material unloaders using this corrected operating time, A predetermined amount of raw material (milk or sugar) is carried out. Now, the outline of the vending machine according to the present invention is as described above, and next, details will be explained using the electric circuit shown in FIG. In this figure, al to a6 are operating means unique to the cocoa sales column 1C, such as a cocoa raw material delivery motor, coffee mixer motor, sugar and milk delivery motor, and first and second coffee solenoid valves, according to instructions from the CPU. Output terminals b to b4, which respectively output operation signals, are operating means specific to the black tea sales column IB, such as a black tea raw material delivery motor, a black tea mixer motor, and a first and second black tea mixer motor.
Output terminals that output operation signals to the solenoid valves according to CPU commands, cl to c4 are operating means specific to the cocoa sales column 1C, such as a cocoa raw material delivery motor, a cocoa mixer motor, and the first and second cocoa solenoid valves. These are output terminals that output operating signals according to CPU instructions, respectively.
In addition, dl to dlo are operating means shared by each item-specific sales column 1 person or IC, such as an operating indicator lamp, a lens for the outlet lid, an ice cutting motor for the ice making device, an ice carry-out solenoid, a hot sales number counter, Coin input date solenoid, total sales counter, milk and sugar quantity increase lamp, cup delivery motor, price display with CP
These output terminals output operating signals in accordance with instructions from U, and each of these output terminals is connected to output terminals R1 to R2□ of the CPU via an intermediate signal converter 5. Therefore, these output terminals will be connected to this signal converter 5 from now on.
Treated as an output terminal. Further, this signal converter 5 appropriately processes the signals R1 to R1□ obtained from the output terminals R1 to R22 (actually R1 to R1□) of the CPU and outputs the operation signal to the output terminal of each of the operation signals. Among them, sales columns IA and IB for each item mentioned above. The output terminals of the operation signals corresponding to each unique operation means of 1C, the ice cutting motor of the ice making device, the ice carry-out solenoid, and the hot sale number counter are operated by appropriately processing the signals from the CPU using AND gates and inverters. an output terminal d, for providing signals and for operating signals corresponding to other common operating means; d2. d3. Signals R6) RIO and RI3 to R1□ from the CPU are directly applied to d6 to dlO as operating signals, respectively. Note that this signal converter 5 is included in the CPU for convenience in the block configuration diagram described above. Next, 6 to 8 are multiplexers so that operation setting signals (voltage values differ depending on each resistor) can be obtained from each of the eight variable resistors in the volume adjuster. When the multiplexer receives the selection signal of the chip selector 9 which selects by the signals R2□, F4 output from the output terminals R23, F4 of the CPU, it selects the scanning signals Fl to F3 obtained from the output terminals Fl to F3 of the CPU. Along with this scanning, the operation setting signals output from each of the variable resistors are sequentially applied to the voltage comparator 14 at the next stage. In addition, each variable resistor of the volume adjuster 2 is provided corresponding to the operating means specific to each item-specific sales column 1 to 1C and the operating means shared by these columns, and its resistance value is variable by external operation by the operator, and by adjusting this, the operating time or amount of the corresponding actuating means is set, and an operation setting signal is output. For example, variable resistor r1 is used to set the operating time of the operating indicator lamp, variable resistor r4 is used to set the operating time of the coffee mixer motor, and variable resistor r24 is used to set the operating time of the coffee mixer motor.
is used to set the price value on the price display. 10 is a pulse generator which oscillates clock pulses at predetermined cycles. 11 is an analog switch and flip-flop 12
is set in the set state by the output signal R22 of the CPU and outputs a signal from its output terminal Q. When it receives such a signal, it becomes conductive, and when it becomes conductive, the clock pulse obtained from the Hanel generator 10 is as follows. Step wave generator 13 and CP
It is designed to be applied to the input terminal β of U. The staircase wave generator 13 outputs a staircase wave indicating a voltage value in response to the clock pulse while the clock pulse is being input.
4, the voltage is compared with the voltage of the operation setting signal from the variable resistor, which is input to the voltage comparator 14 through the multiplexers 6 to 8. The voltage comparator 14 is configured to provide a match signal to the next-stage one-shot pulse generator 15 when these two voltage values match. When the match signal is input from the voltage comparator 14, the - pulse generator 15 outputs a - pulse, and supplies this pulse to the flip-flop 12 through the input terminal R8 to reset the flip-flop 12. At the same time, it is applied to this CPU through the input terminal TAB, and one count operation of the CPU is completed. In short, the above-mentioned multiplexers 6 to 8, chip select 9, pulse generator 10, analog switch 11° flip-flop 12, staircase wave generator 13, voltage comparator 14, and pulse generator 15 work together to control the CPU. According to the command, the signal output from each variable resistor of the volume regulator 2 is sequentially converted into a digital signal with a number of clock pulses corresponding to its voltage value, and the digital signal is supplied to the CPU, and the block shown in FIG. In the general configuration diagram, it is included in the CPU for convenience. In this case, the equipment indicated by these codes 6 to 15,
To explain the relationship with the CPU in a little more detail, the moment the power is turned on, the CPU clears all information stored in the RAM, and then outputs the output terminals R21, R22,
Signals R2, , R22, F, to F from Fl to F4, respectively.
4 and sets the flip-flop 12 in the set state with the signal R2□, and sequentially selects each multiplexer 6 to 8 through the chip selector with the signals R21 and F4, and outputs the signal from the variable resistor input to the selected multiplexer. The signal is sequentially scanned and the volume is read. For example, if the volume is being read for the first time, the chip selector 9 outputs a selection signal of [1, 0, 0] due to the relationship between the CPU output signal R2+ and the output state of F4, and selects the multiplexer 6. to set it to operational state. In this state, the scanning signal Fl given to the multiplexer 6
Assuming that F3 to F3 are logical values at the level [0, 0, 0], the multiplexer 6 transfers only the operation setting signal (indicating the operating time of the operating indicator lamp) output from the variable resistor r1 to the voltage of the next stage. is applied to the comparator 14. On the other hand, at the same time, the flip-flop 12 is set to the set state as described above by the input of the count start signal R2□ from the CPU, and the analog switch 11 is turned on, and the clock pulse output from the pulse generator 10 is input. The signal is inputted to the CPU through the terminal β and also inputted to the staircase wave generator 13. Then, the CPU starts counting the number of clock pulses, and the staircase wave generator 13 generates a staircase wave based on the input of the clock pulses, and sends the staircase wave to the voltage comparator 14 at the next stage. The voltage comparator 14 compares the voltage of this staircase wave with the voltage value of the operation setting signal from the variable resistor r obtained through the multiplexer 6, and when the two voltage values match, A coincidence signal is output and this signal is given to the one-shot pulse generator 15. This pulse generator 15 outputs one reset pulse in conjunction with the input of the coincidence signal, and inputs the reset pulse to the above-mentioned Noritub flop 12 through the input terminal R8. At the same time as resetting, input is sent to the CPU through the input terminal TAB.
The counting operation of the clock pulses is stopped. By resetting the flip-flop 12, the analog switch 11 is rendered non-conductive, thereby preventing the pulse generator 10 from supplying clock pulses to the staircase wave generator 13 and the CPU at the next stage. Furthermore, when the CPU stops the counting operation as described above in response to the input of the reset pulse, it also sends information on the number of clock pulses counted to the RAM and stores it therein. Immediately after, the next variable resistor r2
In order to read the volume of , the states of the scanning signals Fl to F3 are set to C0-0.1] and the count start signal R is set again.
22 is applied to the flip-flop 12 to put it in a set state, and from then on, the same counting operation as in the case of the variable resistor r1 is performed, and the result is stored in the RAM upon completion of counting. In this way, the volume of each variable resistor corresponding to the multiplexer 6 is read, and when the reading is completed, the CPU changes the output states of the output signals R21 and F4 and selects [0. 1.0] to select the next multiplexer I, put it into the operable state, and adjust the volume of each variable resistor corresponding to multiplexer 1 in the same way as for multiplexer 6 above. Read sequentially and store in RAM. When the reading of the volume of each variable resistor corresponding to this multiplexer 7 is completed, the CPU again changes the output states of the output signals R2□ and F4 to send the selection signal [0, 0, 1] from the chip selector 9. is output, selects the next multiplexer 8, sets it to an operable state, and sequentially reads the volume of each variable resistor corresponding to the multiplexer 8, and sequentially stores the results in the RAM. There is. Next, the reference numeral 16 is the output terminal Fl of the CPU.
This is a selector that selects a column of each key switch group in the first and second operation keyboards 3 and 4 according to the scanning signals Fl to F4 output from the first and second operation keyboards 3 and 4. and 4 are each configured by arranging 16 key switches in a matrix of 4 rows and 4 columns, and therefore are provided with 4 output terminals S1 to S4. Each row of each key switch group of each operation keyboard 3 and 4 is connected to input terminals KE and KE4 of the CPU through common OR circuits OR and OR4 for each corresponding row between each keyboard 3 and 4, respectively. In addition, the key switch group of the first operation keyboard 3 is connected to the input terminal A of the CPU via a common OR circuit ORo for each row.
The signal output from this OR circuit ORo is connected to C as a test signal based on the operator's test.
When this signal is input, the CPU performs an operation to carry out a predetermined product even if no coin is inserted, since the product delivery is a test. By the way, the first and second operation keyboards 3 and 4
As mentioned above, each of the 16 key switches is arranged in 4 rows and 4 columns, but as shown in the figure,
The inner code of each key switch on the operation keyboard 3 is A to J.
, M and N correspond to each product in each key switch of the second operation keyboard 4, as well as the selection key switch and correction key switch for each product with the symbols of milk and sugar increase, Also, the code is L, 0. Those marked with P correspond to key switches without symbols on the second operation keyboard 4, and are reserved for use as a backup. Now, to describe the relationship between the selector 16, the first and second operation keyboards 3 and 4, and the CPU in a little more detail, when the entire vending machine is powered on and the CPU is energized, , scanning signals Fl to F4 are sent to the selector 16 from this CPU through output terminals Fl to F4 as [1].

It is given as a signal indicating a logical value of [0] level. In such a state, for example, when the operator presses and turns on the selection key switch marked A for testing on the first operating keyboard 3 in order to test the sale of coffee with milk sugar, the above-mentioned scanning signal F
The moment 1 becomes [1] level, OR circuits ORo and O
Signals are output from R1, and the signal of the OR circuit ORo is input to the CPU through the input terminal AK as a test signal AK, and the signal of the OR circuit OR1 is a selection signal KE.
1 is input to the CPU through the input terminal KE. Then, the CPU recognizes that it is a test sale based on the input of the test signal AK, and determines that no coins have been inserted (and that it is in a state where it is possible to issue a sales operation command to the item-specific sales columns IA, IB, and IC). (In other words, the information stored in the RAM is read out according to the program in the ROM, and based on this information, a sales operation command can be executed to the item-specific sales column 1 to 1C). F4 output status (F1 is [1] level)
Based on the relationship with the input selection signal KE1, it is determined that the selected selection key switch that was pressed is related to coffee with milk sugar, and from then on, each item unique to one sales column is selected according to the program stored in the ROM. The actuating means and the common actuating means are sequentially actuated based on the operation information stored in the RAM to discharge the coffee containing milk sugar. Moreover, instead of carrying out the transport by operating the keyboard 3 dedicated to the operator, if a predetermined coin is inserted and a selection key switch corresponding to, for example, cold cocoa is turned on on the keyboard 4 dedicated to the user, the scanning signal F3 is output. At the moment that becomes the [1] level, a signal is output from the OR circuit OR2, and this signal is sent to the CPU from the input terminal KE2 as the selection signal KE2.
is input. Then, the CPU separately receives a signal from a coin counter (not shown) due to the insertion of the coin, recognizes that it is a normal sale, and displays the sales column IA for each item.
IB becomes in a state where it can issue a sales operation command to the IC, and the output state of the scanning signals Fl to F4 (F3 becomes [1
] level) and the input selection signal KE2, it is determined that the selected selection key switch that was pressed is related to cold cocoa, and from then on, the unique selection of the item sales column 1C is performed according to the program stored in the ROM. Each operating means and the common operating means are sequentially operated based on operating information stored in the RAM to transport cold cocoa. It is desirable that the milk or sugar increase key switch be pressed at the same time as other item-specific selection key switches (limited to coffee-related keys); however, when this key switch is operated, the scanning signal F4 At the moment that becomes the [1] level, the OR circuit OR or OR2 outputs the correction signals KE1' and K.
E2' is output, and this signal is input to input terminal KE1 or KE.
2 is input to the CPU as a milk or sugar increase correction signal. Then, the CPU adds the operating time previously stored in the ROM to the operating time of the milk or sugar transport motor stored in the RAM, and based on the result, controls the milk or sugar transport motor to a predetermined time according to the program in the ROM. It is designed to operate at the right timing to discharge more milk or sugar than usual. The present invention is constructed as described above, and its operation will be explained below with reference to the flowchart shown in FIG. Now, the operator has to adjust the resistance value of each variable resistor of the volume regulator 2, that is, the sales column 1A for each item.
- When the power of the vending machine is turned on while the operating time or amount of the unique operating means and the common operating means of 1C have been set, the CPU once clears the memory contents of the RAM according to the program of the ROM. Thereafter, the operation information of each operating means set in the volume adjuster 2 is read and stored in the RAM, and the entire vending machine is set to a sales standby state. Regarding the reading operation of the operation information set in the volume adjuster 2 in this case, in the section of the explanation of the above-mentioned configuration, in particular, the device indicated by reference numerals 6 to 15 and the CP
Since the relationship with U will be explained in a little more detail, a detailed explanation will be omitted in this function section, but in short, after the CPU clears the RAM, the CPU clears the signal R.
21°F4 to sequentially select each multiplexer 6 to 8 via the chip selector 9;
Each of these multiplexers sequentially supplies an operation setting signal output from each corresponding variable resistor to a voltage comparator 14 based on the state of the scanning signals F to F3 obtained from the CPU during selection, and this comparator 14 The voltage value of the staircase wave obtained by converting the voltage value of these operation setting signals and the clock pulse inputted from the pulse generator 10 to the staircase wave generator 13 through the analog switch 11 controlled by the Noritub flop 12 is determined. - Comparison is made, and each time the two match, the CPU's counting operation is stopped through the one-shot pulse generator 15, and the counting results are sequentially stored in the RAM. Now, when the vending machine is set to the sales waiting state as described above, the operator is now conducting the first test to test the sales status of cold coffee with milk and sugar in the case of increased sugar content. When the selection key switch E and the correction key switch N on the operation keyboard 3 are pressed, the OR circuit OR6 is activated at the moment the scanning signal F2 reaches the [1] level.
A test signal AK and a selection signal KE1 are output from OR1, respectively, and these signals are input to the CPU through input terminals AK and KE, respectively, and immediately after that, when the scanning signal F4 reaches the [1] level, they are output from the OR circuit OR2. A correction signal KE2' is output, and this signal is input to the CPU through the input terminal KE2. Then, the CPU recognizes that it is a test sale based on the input of the test signal AK, and displays the item-by-item sales column IA even if no coins are inserted. IB and IC are now in a state where they can issue sales operation commands.
And the output state of the scanning signals Fl to F4 (F2 is [
1] level) and the input selection signal KE1, it is determined that the selected selection key switch that was pressed is related to cold coffee with milk sugar, and the output status of the scanning signals Fl to F4 (F4 is [1] level) and the correction signal KE2', it is determined that the correction key switch that was pressed is related to the sugar increase, and the ROM is stored in advance.
The operating time stored in the storage area is added to the operating time of the sugar transport motor stored in the RAM, and the result is temporarily stored in the RAM. When the reading of the key switch input accompanying the key switch operation is completed, the CPU thereafter reads the sales column 1 by item according to the program stored in the ROM.
The unique operating means and the common operating means of A are sequentially operated based on the operating information (operating time) stored in the RAM, and cold coffee containing milk sugar with an increased amount of milk is delivered. In Komata, a series of unloading operations based on the CPU commands are performed in the fourth stage.
This will be explained with reference to the time chart shown in the figure. In this embodiment, this unloading operation is completed in 12 seconds. When the reading of the key switch input is completed as described above, the CPU first outputs the output terminals R6, R,. and R13 output signals R6, R, o, and R13, and based on these outputs, the operation signal output terminals d7. d2. Outputs the d3 and d6 OK operation signals, turns on the operating indicator lamp, and operates the receptacle for the outlet lid to prevent the outlet lid from opening, while driving the ice cutting motor of the ice making device to enable ice to be taken out. At the same time, the coin insertion day solenoid is activated to prevent the coin from being inserted into the coin insertion slot (Fig. 4 A, B,
(Refer to the waveforms in Figure 1).The operation of each of these operating means, except for the ice cutting motor, continues until the unloading operation is completed. After issuing an operation command to each of these common operation means, the CPU then outputs a signal R16 to output an operation signal from the output terminal d of the signal converter 5 for a certain period of time (1 second), and then the cup delivery motor to transport the cup to the outlet. (Refer to the waveform in Figure 4.) Following this, the CPU sends the signal R.
5 and R11 respectively to output terminal a5 of the signal converter.
And by outputting an operation signal from d4, the first electromagnetic valve for coffee is operated to start supplying hot water to the coffee mixer, and the ice carrying solenoid is operated to carry out the ice block to the cup that has been carried out (the first (See the waveforms in Figure 4, G and C). The first electromagnetic valve continues to operate until the unloading operation is completed, but the ice unloading solenoid is stopped in 2 seconds. Also, during the operation of this ice removal lens 2, the CPU first performs the following operations:
The signal R2 is outputted to output an operation signal from the output terminal a2 of the signal converter 5 to start the operation of the coffee mixer motor, and the signal R3 is output directly (0.5 seconds later) to the signal converter 5. By outputting an operation signal from the output terminal a3 of , the sugar conveying motor is operated and the sugar is conveyed to the coffee mixer. (Refer to waveform O in Figure 4) Since the sugar removal operation time is the operation of the sugar increase correction key switch N as described above, the predetermined time 3 stored in the RAM as in the calculation described above. .ROM in 3 seconds
Add 1 second of memory correction time to 4 or 3 seconds. Further, the operation of the coffee mixer motor is stopped 1.2 seconds after the sugar removal is completed (therefore, the total operating time is 6 seconds). Next, the CPU immediately after the start of carrying out the sugar (0,3
seconds later), the signal R7 is output to the output terminal a of the signal converter 5.
6. By outputting the operation signal from the second coffee
The electromagnetic valve is operated to supply hot water to the coffee mixer together with the first electromagnetic valve to melt the sugar being delivered to the mixer. (Refer to the waveform in the fourth diagram) Subsequently, the CPU executes the following command while the coffee mixer motor is operating (1 and 2 when the motor stops operating).
By outputting the signal R4 from the output terminal a4 of the signal converter 5 to output the operating signal from the output terminal a4 of the signal converter 5, the milk delivery motor is operated to carry out the milk to the coffee mixer and the milk starts to be carried out. Immediately after (0,2

By outputting an operation signal from 1, the coffee raw material delivery motor is operated to transport the coffee raw material to the coffee mixer (see the waveform in Figure 4), and these milk and coffee raw materials are transferred to the coffee mixer in the coffee mixer. The mixture is diluted and mixed with hot water supplied from the first and second solenoid valves, and is poured into a waiting cup with ice cubes added at the outlet, in tandem with the sugar water from the sugar removal process. The time when the milk and coffee raw materials are completely discharged is 11 seconds after the start of a series of discharge operations, and at the same time, the signals R7 and R10 are deactivated and the first coffee solenoid valve and the ice making device are turned off. The cutting motors each stop their operation. After that, when one second has elapsed, the CPU de-energizes the signal R6 and stops the operation of the operating indicator lamp, the outlet lid nozzle, and the first coffee solenoid valve, and outputs the signal R14 at this final stage. and the output terminal d7 of the signal converter 5
A series of unloading operations is completed by outputting an unloading completion signal and sending this to the total sales counter to count up, and after receiving a signal indicating that the cup has been taken out from the unloading port, a signal is output. Deenergize R13 to stop the operation of the coin insertion Ronlenoid. The hot water poured from the first electromagnetic valve for coffee during this final one second washes the inside of the passage and is poured into the cup. When the series of unloading operations are completed as described above and the operation indicator lamp goes out, the outlet cover can be opened and the cup can be taken out. The above is the operation of test sales by an operator.Next, normal sales by general users will be explained using an example. Now, when the user inserts a predetermined coin into the coin slot to purchase tea and presses the selection key switch related to tea on the second operation keyboard 4, the scanning signal F1
At the moment when the signal becomes the [1] level, the selection signal KE4 is outputted from the OR circuit OR4, and this signal is inputted to the CPU through the input terminal KE4. Then, the CPU receives a signal from the coin counter due to the insertion of the coin, recognizes that it is a normal purchase and sale, and is in a state where it can issue a sales operation command to each item-specific sales column 1 to 1C. The above scanning signals Fl to F
It is determined that the selected selection key switch that was pressed is related to black tea based on the relationship between the output state of F4 (F4 is [L] level) and the input selection signal KE4, and the key switch input associated with the operation of the selection key switch is performed. Complete loading. Thereafter, the CPU sequentially operates each unique operating means and common operating means of the item sales column 1B based on the operating information (operating time) stored in the RAM according to the program stored in the ROM, and takes out the hot tea. In this process, the series of unloading operations based on this CPU command is performed in the fifth step.
This will be explained with reference to the time chart shown in the figure. When the reading of the key switch input is completed as described above, the CPU first outputs the signals R6, R, 3, and based on these, the output terminals d1. Operation signals are outputted from d2 and d6, respectively, and the operating indicator lamp is turned on, and the solenoid for the outlet cover is operated to prevent the outlet cover from being opened, while the coin insertion date solenoid is operated to prevent coins from being inserted into the coin input slot. prevent it. Note that the operation of each of these actuating means is continued until the series of unloading operations is completed. Next, the CPU outputs a signal R16 to output an operation signal from the output terminal d of the signal converter 5 for a certain period of time (1 second) to operate the cup carry-out motor and carry out the cup to the outlet. (Refer to the waveform in Figure 5) Following this, the CPU outputs the signal R1.
) Output R8 to the output terminals bl to b of the signal converter 5
By outputting operation signals from 3, the black tea raw material delivery motor, the black tea mixer motor, and the first black tea solenoid valve are respectively operated, and the black tea raw materials and hot water are transported to the black tea mixer, and these are mixed in the mixer. Dilute and mix. (See the waveforms in Figure 5.) In this case, the black tea raw material delivery motor operates for 3.5 seconds, and then stops its operation together with the de-energization of the signal R1. Further, the CPU outputs a signal R7 immediately after the start of operation of the black tea raw material carrying motor etc. (after 1.5 seconds) to operate the second solenoid valve for black tea from the output terminal b4 of the signal converter 5 (the fifth (Refer to the waveform of the force), together with the first electromagnetic valve mentioned earlier, hot water is supplied to the black tea mixer to further dilute the black tea raw material carried out. The operations of the black tea mixer motor and the first and second electromagnetic valves are stopped by deactivating the signals R7 and R8 11 seconds after the start of the series of unloading operations. Then, after one second has elapsed, the CPU sends the signal R

is output to output a carry-out completion signal from the output terminal d7 of the signal converter 5, and this is sent to the total sales counter to count up, thereby completing a series of carry-out operations.
Further, after appropriately receiving a signal indicating that the cup has been taken out from the outlet, the signal RI3 is deenergized to stop the operation of the coin insertion port solenoid and prepare for the next sale. In addition, at an appropriate timing during this series of unloading operations, the CPU
outputs the signal R1□ and connects it to the output terminal d5 of the signal converter 5.
A single signal is outputted to cause the hot sales number counter to count that one hot beverage has been sold. The above are examples of a series of dispensing operations in accordance with the operations of the first and second operating keyboards in the vending machine according to the present invention. , by operating the respective operation keyboards as appropriate.
Needless to say, it is also possible to carry out products such as those shown on the selection key switches and correction key switches of the second operation keyboard. The series of unloading operations for these other products is largely the same as in each of the above-mentioned examples, so a description thereof will be omitted, but the point is that the operator or general user selects the desired selection key switch on each operation keyboard and In addition, when the correction key switch is operated and the key switch input resulting from such operation is read into the CPU, the CPU
According to the program stored in the RAM, each operating means of the item-specific sales column corresponding to the selected product and each operating means shared by all item-specific sales columns are sequentially operated based on the operation information stored in the RAM. The desired product is transported out. Although it was not explained in the above operation section, the operation signal given to the increaseable lamp from the output terminal d8 of the output converter 5 is output when the signal R15 is output from the CPU and contributes to the lighting of the lamp. The CPU appropriately detects that the milk or sugar tank has run out of these raw materials, and stops outputting the signal R15 to turn off the power and turn off the lamp. Further, the operation signal given to the price display from the output terminal d1o is related to the product price stored in the RAM, and is C
Based on signal RI7 output from PU. The present invention is constructed as described above, and in short, each actuating means is sequentially operated by operating a key switch, and based on such operations, various raw materials are cooked into desired products, and the output port is opened. In the product which is led to the market and offered for sale, at least a volume adjuster for variably setting the operating time of each of the above-mentioned operating means, a first memory such as a ROM that stores programs etc. related to various operations, and a central processing unit that operates according to a program in a first memory; and a second memory such as a RAM that stores the operating time of each actuating means set in the volume adjuster according to the operation of the central processing unit. When the central processing unit reads the key switch input by operating the key switch, the central processing unit accordingly executes the program according to the program in the first memory and the operating time stored in the second memory. Each actuating means is operated in sequence, and through this series of operations various raw materials are cooked and delivered as desired products to the outlet to provide a vending machine for sale. The operating time can be finely adjusted, and therefore products in extremely good cooking condition can be sold. Further, in the present invention, in addition to programs related to various operations, the first memory stores a correction value for the operating time of a specific actuating means, and in addition to the above-mentioned key switch, a correction value for correcting the operating time is stored in the first memory. A key switch is provided, and when both of these key switches are operated, the second
This is because the specific operating means is operated with the operating time stored in the memory corrected by the correction value of the first memory, and the operator can select the degree of cooking of the product to be carried out. This is an excellent invention that can contribute to the sale of products that are even more suited to users.
