DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a timer control method for a vending machine that operates according to a plurality of timer sequences.

B. Prior Art An example of a vending machine equipped with multiple timer sequences is a cup-type coffee vending machine.

Figure 1 shows the material mixing configuration of a cup-type coffee vending machine, which is equipped with drive motors 7, 8, and 9 for dispensing coffee, sugar, and milk powders, and a solenoid valve 6 for discharging hot water. Each powder material is mixed with hot water from the layer 10' and discharged from the cup 11'. At this time, the drive motors 7, 8, 91 and solenoid valve 6 are designed to operate according to the timer sequence shown in Fig. 2, but each powder material has a different concentration depending on the material manufacturer and also depends on the size of the cup used. Because there are also differences in drive motors 7, 8, 9
The drive times of and 6 are variable within a certain range with respect to the standard time. Traditionally, such timer control has generally been controlled by a so-called cam timer that combines a motor and a cam switch, but in recent years it has become possible to control vending machines using semiconductor circuits both economically and technologically. As for the setting of this timer time constant, it has become advantageous to set data using a keyboard and to store data using a semiconductor memory backed up by a battery. However, in this type of system, if the data in the semiconductor memory changes significantly due to reasons such as a long-term power outage, the mixing ratio may become erroneous, resulting in bad-tasting coffee being poured out or coffee overflowing from the cup. C. Purpose of the Invention In light of the above, the present invention provides a timer control method for a vending machine that automatically sets a predetermined standard timer date when the set timer data deviates from a reference value. .

D Example FIG. 3 is a block diagram showing an embodiment of the present invention.

Keyboard 1 is r coffee,” “sugar,” “milk,” and “hot water.”

SK), an end key (EK), a numeric keypad 14 for setting timer data, and a decimal point key 15. And the memory 2A dedicated to lectures is the memory section M, 'M.
Hot water, coffee, and sugar for 21st floor and M4 respectively. Standard timer data regarding milk is set. The microprogram control device 3 has built-in programs for timer data setting and vending operation, and the start key (SK)
An operation program is selected by the operation or input of a sales signal, and control is performed based on the program. Also gate g. ...The fleas are configured to become conductive or non-conductive according to a gate signal output from the microprogram control device 3 according to a program. Rewritable memory 2
The memory area M,′ corresponds to hot water, coffee, sugar, and milk.
・M2', M3', and M4', and a predetermined storage section is called up by address information introduced from the microprogram control device 3 through the gate &. The comparison means 4 also includes standard timer data for each hot water, coffee, sugar, and milk extracted from the memory 2A by the microprogram control device 3 and introduced through the gate g2, and set timer data stored in the memory 2. A determination signal J is output as to whether or not they match within the reference value range. When the comparison means 4 inputs a judgment signal J indicating that the standard timer data and the set timer data do not match within the reference value range, the microprogram control device 3 transfers the standard timer data from the memory 2A to the memory 2. Write. During the sales operation, the control device 3 reads the timer data from the memory 2 to the sales control device 5, and the sales control device 5 controls the driving of the solenoid valve 6 and delivery motors 7, 8, and 9 based on these timer constants. It is. The operation of the above structure will be explained with reference to the flowcharts shown in FIGS. 5 and 6.

First, when setting timer data, press the start key (S
When K) is operated, the control device 3 selects a timer data setting program and starts controlling the timer data setting. Then, when the function key 12 is operated, the control device 3 conducts the gates &, and the storage portions M, ', M of the memory 2 corresponding to the material specified by the function key.
The address information of 2', M3', and ship's side is output and set to a writing state. Then, when predetermined timer data is entered by operating the numeric keypad 13 and, if necessary, the decimal point key 14, this data is written into the addressed storage section. For example, when the "coffee", "4", "..."2" keys are operated in sequence, the timer time 4.2 sand related to coffee raw material delivery is set, and the memory section M2'' corresponds to this timer time. A predetermined value is stored in binary code. Since the timer control in this example is achieved by clock pulses generated every 0.1 seconds, when 4.2 seconds is set in the control device 3, the memory unit' stores ``42'' in binary code. Write. In this way, function key 1 for each material
2 and then by operating the numeric keypad 13, an arbitrary timer time is set in the memory 2, and after the setting is completed, the control device 3 cancels the timer data setting mode by operating the end key (EK).

On the other hand, if the timer data setting mode is not designated by the start key, the control device 3 performs processing in a sales standby state.

That is, the control device 3 controls the gate g. is made conductive, and the address information of the memory sections M,', M2'', M8', and M4' of the memory 2 is sequentially outputted to create a continuous output state, and the memory sections M,', M2', and
The timer data at M3'.M is introduced into comparison means 4. Then, the control device 3 makes the gate & conductive and the memory 2A
Memory section M.・The address information of M2, Pigeon, and M4 is sequentially output to make it into a logical state, and the memory section M. - Introduce the standard timer data of M2, Pigeon, and M4 to the comparison means 4. Then, the comparison means 4 compares the set timer data for each material with the standard timer data, and holds the set timer data in the memory 2 that match within the reference value range, but controls if they do not match. The device 3 connects the gate shaft and the gate, first outputs the address information of the memory section M, and then outputs the address information of the memory section M,
The standard timer data of M, is outputted, and then the address information of the memory section M,' is outputted, and the standard timer data of M, is written in M,'. Then, in the same manner, the standard timer data of M is read by outputting the address information of the storage unit M,
Output the address information of the memory section M2' and write the standard timer data of the ship in M2', then read the standard timer data of M3 by outputting the address information of the memory section Dove, and output the address information of the memory section M3'. Then, write the standard timer data of M3 to M3', output the address information of the memory section M4 to read the standard timer data of M, output the address information of the memory section', and read the standard timer of M8 M4. Write data. In addition, when comparing the aforementioned set timer data and standard timer data, for example, for coffee, 1 second is set as the standard value, and the comparison means 4
The difference between the set timer data and standard timer data is 1
If it is within the range of seconds, the set timer date will be considered normal and ±
If it exceeds the range of 1 second, it is determined that the set timer data has changed. Therefore, in the sales standby state, abnormalities in the set timer data are always determined by comparing the set timer data with the standard timer data, and in order to adopt the standard timer data in the event of an abnormality, appropriate measures are taken to prevent the contents of memory 2 from disappearing. Protection can be achieved. When a predetermined amount of money is inserted into the vending machine and a vending signal is input from a coin processing device (not shown), the control device 3 executes a vending operation program. First, the control device 3 controls the gate g.・Make the fly conductive and output the address information of the memory section M,' to M,
It outputs the timer data of ', then outputs the address information of the storage section T, and writes the timer data of M,' to T. Thereafter, the address information of the memory section M2' and the address information of the memory section L are sequentially output to the machine, the timer data of the pond' is written to T2, and the address information of the memory section' and the address information of the memory section circle are output. The timer data of M3' is sequentially outputted to T3, and the address information of the storage section M4' and the address information of the storage section L are sequentially outputted and the timer data of M4' is written to T4. FIG. 4 shows the configuration of the sales control device 5, in which the memory 14 for Kendeson is preset with start data indicating the start time of sending out after the generation of the sales signal for each material. If the generation of the sales signal according to the timing chart in Figure 2 is To, then t.・ra・t

is set to .

The start data set in the memory 14 is read by the control device 3 turning on the gate & and sequentially outputting the address information of the memory sections t2', t2', t4'. Flip-flop circuit circuit 15, 16, 17, 1
8 corresponds to hot water, coffee, sugar, and milk, respectively.
At the set end and reset end, there is a gate G.・G2...G8 is connected. When the counting operation is set by the control device 3, the counting device 19 counts clock pulses inputted every 0.1 seconds, and the coincidence detection device 20 is configured to read the clock pulses from the memory by the control device 3 every time the counting device 19 counts. The start data for each material read from 14 is compared with this count value CT, and if a match is detected, a set signal is output. That is, in the flowchart of FIG. 6, the control device 3 turns on the gates g8 and ◯2, first specifies the address of the storage section 1', and introduces the start data t, into the coincidence detection device 20. When the count value CT of the counting device 19 reaches the start date, a coincidence output from the coincidence detection device 2 is generated and introduced into the set end of the flip-flop circuit 15 through the gate G2. Therefore, the flip-flop circuit 15 is set, the solenoid valve 6 is driven, and hot water is poured out. Next, the control device 3 maintains the conduction of the gate &, specifies the address of the storage section 2', introduces the start data etc. into the coincidence detection device 20, and makes the gate G4 conductive. Eventually, when the count value CT of the counting device 19 reaches one point below the start data, the coincidence output generated by the coincidence detection device 2 is introduced to the set end of the flip-flop circuit 16, and the setting of the flip-flop circuit 16 causes the sending motor 7 to start. The coffee raw material is delivered by driving. and control device 3

When the count value CT reaches the start data t3, the flip-flop circuit 17 is set by the coincidence output of the coincidence detection device 20, and the delivery motor 8 is driven to send out sugar. Then, the control device 3 keeps the gate scale conductive and stores it in the memory section t4'.

By setting 8, the delivery of hot water, coffee, sugar, and milk is started in the order shown in the timing chart of FIG. Thus, the control device 3 turns on the gate &, specifies the address of the storage section T4, sends the timer data stored in T4 to the adding device 24, and then turns on the gate g8 to specify the address of the storage section L'. The specified start data stored in L' is outputted to the adder 24. Then, the adding device 24 adds the start data of the timer gate T4 and the start data of ', and the control device 3 makes the gate G7 conductive. Eventually, when the count value CT of the counting device 19 reaches the addition value (t40L) of the adding device 21, a coincidence output is generated in the coincidence detection device 22 and sent to the flip-flop circuit 1 through the gate G7.
8 and is introduced into the reset terminal R of 8. Therefore, the flip-flop circuit 16 is reset, the delivery motor 9 stops operating, and the milk delivery operation is completed. Next, control device 3

to humble myself. When the addition value (RA+T3) by the addition 21 reaches the count value CT, the coincidence output generated in the coincidence detection device 22 is sent to the reset machine R of the flip-flop circuit 17 by the control device 3 because the gate G5 is activated. be introduced. Therefore, the flip-flop circuit 17 is reset, the delivery motor 8 stops operating, and the sugar delivery operation is completed. Then, the control device 3 turns on the gate g8, specifies the address of the storage section L, reads out the timer data stored in T2 to the adding device 21, and then turns on the gate g8 and specifies the address of the storage section t2'. Then, the start data t2 stored at t2' is read out to the adder 21. When the addition value (R + T2) generated by the adding device 211 reaches the count value CT, the coincidence output generated in the coincidence detection device 22 is outputted to the reset terminal of the flip-flop circuit 16 by the control device 3 because the gate G3 is turned on. Introduced into R.
Therefore, the flip-flop circuit 16 is reset, the delivery motor 7 stops operating, and the coffee delivery operation is completed. Then, the control device 3 makes the gate & conductive and the memory section T
, and sends the timer data stored in T, to the adder 21, then turns on the gate saddle, designates the address of storage section t,', and sends the timer data stored in T, to the adder 21. The data are read out to the adder 21. When the addition value (t, 10T,) by the addition device 21 reaches the count value CT, the coincidence output generated in the coincidence detection device 22 is controlled by the control device 3 so that the gate G is connected to the flip-flop circuit. 15 is introduced into the reset machine R. Therefore, the flip-flop circuit 15 is reset, the solenoid valve 6 stops operating, and the hot water pouring operation is completed. In this way, the control device 3 sequentially outputs the start data et al., t2, et al., t4 and each timer data set in the timer data memory 12, adds them in the adding device 21, and adds the addition result to the count value CT. The flip-flop circuit 18,
By resetting 17, 16, and 15 in sequence, the delivery of milk, sugar, coffee, and hot water is completed in the order shown in the timing chart in FIG. Reset to return to initial state. E. Effects of the Invention According to the present invention, the timer time can be freely changed within the standard value range by the vending machine manager, and the desired rumor preference can be set according to the setting location of the vending machine. I can do it.

Moreover, if the set timer data deviates from the standard value due to a setting error or long-term power outage, the corresponding standard timer data is automatically set in place of the set timer data, so there is no malfunction and stable vending is possible. The operation of the machine is expected.
