Description

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.

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

Fig. 1 shows the material mixing mechanism of a cup-type coffee vending machine, in which drive motors 7, 8, 9 deliver powdered coffee, sugar, and milk ingredients, and a solenoid valve 6 discharges hot water.
Each powder material is mixed with hot water from the rope clothing layer 101 and poured into a cup 11. At this time, the drive motors 7, 8, 9 and the solenoid valve 6 are designed to operate according to the timer sequence shown in Figure 2, but each powder material has a different concentration depending on the material manufacturer, and the size of the cup used There are also differences depending on the drive motors 7, 8, 9.
The driving time of the solenoid valve 6 is variable within a certain range with respect to the standard time. Conventionally, 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. Therefore, it has become advantageous to set the timer time constant by setting the data using a keyboard and storing it in a semiconductor memory backed up by a battery. However, with 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 incorrect, resulting in bad-tasting coffee being poured out or coffee overflowing from the cup. 1. Purpose of the Invention In view of the above points, 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. be.

8 Examples FIG. 3 is a block diagram showing an embodiment of the present invention.

Keyboard 1, which is a data input means, has function keys 1 for selecting "coffee,""sugar,""milk," and "hot water."
2, a start key SK, an end key EK, a numeric keypad 13 for setting timer data, and a decimal point key 14. The memory 2A dedicated for discussion is the storage section M.・Standard timer data regarding hot water, coffee, sugar, and milk are preset for ground, M3, and M, respectively. The microprogram control device 3 has a built-in program for setting timer data and vending operation, and selects an operation program by operating the start key SK or inputting a vending signal, and performs control based on the program. Further, the gates & . . . are configured to become conductive or non-conductive in accordance with a gate signal output from the microprogram control device 3 according to a program. The rewritable memory 2 has memory sections M,', M2', and ``chi'' corresponding to hot water, coffee, sugar, and milk, and addresses introduced from the microprogram control device 3 through the gate g4. A predetermined storage section is called up depending on the information. Comparison means 4 also includes standard timer data for each hot water, coffee, sugar, and milk that is read out from memory 2A by microprogram control device 3 and introduced through the gate line, and standard timer data for each of hot water, coffee, sugar, and milk that is read out from memory 2 and introduced through gate &. The set timer data is sequentially compared with the set timer data, and if the same type of timer data match within a predetermined reference value range, a match signal is output to the microprogram control device 3. When a matching signal is input for each material from the comparison means 4, the control device 3 introduces the setting timer data in the memory 2 to the sales control device 5. However, if a matching signal is not introduced for any material, all of the data in the memory 2A is input. The screen timer data regarding the material is introduced into the sales control device 5.
Therefore, the vending control device 5 stores the introduced setting timer data or standard timer data in the timer data memory 1.
5, and based on this timer constant, the solenoid valve 6 and delivery motors 7, 8, and 9 are driven to perform the sales operation. The operation according to the above configuration will be explained with reference to the flowcharts shown in FIGS. 5 and 6.

First, when setting the timer date, press the start key SK.
When 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 makes the gate shaft conductive, and the memory section M,', M2' of the memory 2 corresponding to the material specified by the function key is activated.
・Output the address information of M3' and M4' and set it to the write state. Then, when predetermined timer data is keyed in 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", ".", and "2" keys are operated in sequence, a timer time of 4.2 seconds is set for sending out coffee ingredients, and the memory unit M2' corresponds to this timer time. A predetermined value is stored in binary code. Since the timer control in this example is achieved by a clock pulse generated every 0.1 seconds, when the control device 3 is set to 4.2 stages, the memory unit M2' stores "42" in binary code. Write. In this way, each material has 12 function keys.
If you then operate the numeric keypad 3, the desired timer time will be set in the memory 2, and after completing the setting, press the end key E.
By operating N, the control device 3 cancels the timer data setting mode. 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 selects a vending operation program and controls the vending operation.

First, the control device 3 turns on the gate g to output the address information of the storage section M,' of the memory 2, and also turns on the gate g to output the contents of M,' to the comparison means 4. Next, the control device 3 makes the gate & conductive, and the storage section M of the memory 2A,
At the same time, the address information of M is outputted, and the gate g2 is made conductive to read the contents of M and the comparing means 41. Therefore, the comparison means 4 compares the contents of M,' and M, and outputs a coincidence signal to the control device 3 if they match within the reference value range. For example, 1 second is set as the reference value range for hot water, and the comparison means 4 calculates the difference between the set timer data stored in M,' and the standard timer data stored in M, regarding hot water. If it is within the range of +1 second, a matching signal is output. When the coincidence signal is input, the control device 3 makes the gate 9 conductive to output the address information of the storage area' of the memory 2, and also makes the gate & conductive to read the contents of M2' to the comparison means 4. Subsequently, the control device 3 makes the gate & conductive to output the address information of the storage section M2 of the memory 2A, and at the same time makes the gate g2 conductive to read out the contents of M2 to the comparison means 4. Comparison means 4 then compares the contents of pond' and M2, and outputs a coincidence signal if they match within a predetermined reference value range. Thereafter, every time a coincidence signal is input, the control device 3 sequentially reads out the contents of dove' and M3' and the contents of M4' and M4 to the comparing means 4. When a match signal is inputted from the comparing means 4 in all comparisons, the control device 3 makes the gate gate conductive to output the address information of the memory section M,', and then makes the gate & conductive to output the address information of the memory section M,'. The address information of the storage unit T, of is outputted, and the gate scale is made conductive to write the contents of M,' to T,. Similarly, M2' and T
2, writes the contents of M2' to T2, and writes M3' to T2.
and the circle and write the contents of M3' into T3, and address the pond and T4 and write the contents of M4' into T4. However, if a match signal is not introduced from the comparison means 4, the control device 3 g4 is made conductive to output the address information of the memory section M., then gate & is made conductive to output the address information of the memory section T, of the timer data memory 5, and gate g6 is made conductive to output the address information of the memory section M. Write the contents to T. Similarly, address M2 and L and write the contents to T.
2, address the ground and circle, write the content of the ground to T3, address MZ and T4, and write the content of the ground to L. In this way, an abnormality in the set timer data is determined by sequentially comparing the same type of set timer data and standard timer data each time a sales signal occurs, and if even one does not match, all timer sequences are Since standard timer data is adopted, appropriate protection against erasure of the contents of the memory 2 can be achieved. FIG. 4 shows the configuration of the sales control device 5, and the memory 17 dedicated to selling is preset with start data indicating the start time of sending after the sales signal is generated for each material. According to the timing chart in Figure 2, if the occurrence of the sales signal is a circle, then t.・ra・t
3 and t4 are memory parts t,', t2', t3', and t4', respectively.
is set to .

Further, the start data set in the memory 17 is transferred from the storage section by the control device 3 making the gate & conductive.
It is revealed by sequentially outputting the address information of 3' and t4. Flip-flop circuits 18, 19, 20, and 21 correspond to hot water, coffee, sugar, and milk, respectively, and a microprogram control device 3 is installed at the set end and reset end.
Gate whose conduction is controlled by the gate signal output from ○.・G2...G8 is connected. When the counting operation is set by the control device 3, the counting device 22 becomes “0”.
．． It counts clock pulses input every second.
The match detection bag counter 23 compares this count value CT with the start data for each material retrieved from the memory 17 by the control device 3 every time the counting device 22 counts, and outputs a set signal when a match is detected. That is, in the flowchart of FIG. 6, the control device 3 turns on the gates g3 and G2, first specifies the address of the storage section L', and introduces the start data into the coincidence detection device 23. However, the counting device 22
When the count value CT reaches the start data t, a coincidence output is generated in the coincidence detection device 23 and introduced into the set end of the flip-flop circuit 18 through the gate G2. Therefore, the flip-flop circuit 18 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 ', and introduces the start data t2 into the coincidence detection device 23, and
4 becomes conductive. Eventually, the count value CT of the counting device 22
When the start data is reached, the coincidence output generated by the coincidence detection device 23 is introduced to the set end of the flip-flop circuit 19, and the set end of the flip-flop circuit 19 drives the delivery motor 7 and the coffee material is delivered. Then, the control device 3 keeps the gate g8 conductive and stores the memory section t.
3' and turns on the gate G6. When the count value CT reaches the start data,
The flip-flop circuit 20 is set by the coincidence output from the coincidence detection device 23, and the delivery motor 8 is driven to send out sugar. Then, the control device 3 specifies the address of the storage section t4' while keeping the gate Q conductive, and makes the gate Q conductive. Thereafter, when the count CT reaches the start data, the flip-flop circuit 21 is set by the coincidence output of the coincidence detection device 23, and the delivery motor 9 is driven to dispense milk. In this way, the control device 3 sequentially outputs the start data et.
By setting 20 and 21, 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 makes the gate & conductive, specifies the address of the storage section T4, sends the timer data stored in T4 to the addition device 24, and then gate
8 is made conductive, the address of the storage section ' is specified, and the start data L stored in the storage section ' is outputted to the adder 24 .

Then, the adding device 24 adds the start data of the timer booter t4' of T4, and the control device 3 turns on the gate G7. When this happens, a coincidence output is generated in the coincidence detection device 25, which is introduced through the gate G7 to the reset terminal R of the flip-flop circuit 21. Therefore, the flip-flop circuit 21 is reset, the delivery motor 9 stops operating, and the milk is not delivered. The operation is completed.Next, the control device 3 makes the gate seal conductive, specifies the address of the storage section T3, sends the publicly stored timer data to the adding device 24, and then makes the gate & conductive and stores the timer data. Part t3
After specifying the address of ', the start data stored in '' is output to the adder 24. When the added value (t30L) by the adding device 24 reaches the count value CT, the coincidence output generated in the coincidence detection device 25 is controlled by the control device 3 so that the gate G5 is controlled by the flip-flop circuit 2.
0 to the reset terminal R. Therefore, the flip-flop circuit 20 is reset, the delivery motor 8 stops operating, and the sugar delivery operation is completed. Then, the control device 3 makes the gate conductor conductive, specifies the address of the memory section T2, and
Read out the timer data stored in the adder 24, then turn on the gate g8, designate the address of the memory section, and read out the start data stored in the adder 24.
to humble myself. Then, the added value by the adding device 24 (t20L)
When reaches the count value CT, the coincidence output produced by the coincidence detection device 25 is introduced by the control device 3 into the reset terminal R of the flip-flop circuit 19 due to the conduction of the gate G3. Therefore, the flip-flop circuit 19 is reset, the delivery motor 7 stops operating, and the coffee delivery operation is completed. Then, the control device 3 makes the gate & conductive, specifies the address of the memory section T, and reads out the timer date stored in T, to the adder 24, and then makes the gate & conductive and specifies the address of the memory section T,'. The start data t, which is stored at the address specified, is read out to the adder 24.
When the addition value (t, 10T,) by the addition device 24 reaches the count value CT, the coincidence output generated in the coincidence detection device 25 is controlled by the control device 3 so that the gate ○, is introduced into the reset terminal R of. Therefore, the flip-flop circuit 18 is reset, the solenoid valve 6 stops operating, and the hot water pouring operation ends. In this way, the control device 3 inputs the start data et al.
4 and each timer data set in the timer data memory 15 are sequentially calculated and added by the adding device 24,
By resetting the flip-flop circuits 21, 20, 19, and 18 when the addition result matches the count value CT, the delivery of milk, sugar, coffee, and hot water is completed in the order shown in the timing chart of FIG. 2, and the sales operation is started. Once completed, the control device 3 resets the counting operation of the counting device 22 and returns to the initial state. Effects of the Invention According to the present invention, the setting of the timer time can be changed by the vending machine administrator within the standard value range, and the desired floor setting can be set according to the installation location of the vending machine. .

Furthermore, if even one of the stored timer data changes, all of the timer data will be set to the standard timer data, so stable operation of the vending machine is expected. Even if the data deviates from the reference value due to a setting error, there will be no malfunction because it operates with standard timer data.
