Problems to be Solved by the Invention However, in the above system, as can be seen from the syrup flow rate-adjustment amount characteristic of the syrup viscosity side flow rate adjustment valve shown in FIG. Since the change in flow rate (inclination of α and β) with respect to the change in quantity is rapid, fine adjustment is difficult and flow rate fluctuations are large.

In view of the above problems, the present invention has the same circuit configuration as the conventional one,
Furthermore, the present invention provides a beverage dispensing amount setting method for a vending machine that ensures an accurate dispensing amount of various syrups.

Means for Solving the Problems In order to solve the above problems, the beverage dispensing amount setting method of the vending machine of the present invention dilutes the syrup with carbonated water or carbonated water and cold water or dilution water such as cold water or hot water. The discharge amount of the dilution water per unit time, the discharge amount of multiple types of syrup per unit time, the discharge opening of the syrup from the start of discharge of the dilution water, and the value corresponding to the syrup viscosity are respectively arbitrarily determined. First, a certain discharge amount is selected from among the discharge amounts per unit time of multiple types of syrup in response to the specified value corresponding to the syrup viscosity, and the syrup amount is calculated from the mixing ratio of syrup to the total amount. , calculate the amount of carbonated water from the total amount and the carbonic acid concentration, calculate the amount of cold water from the total amount, the syrup amount, and the amount of carbonated water, and calculate the amount of discharge per unit time from the amount of each discharge amount. This is to calculate the ejection time.

Function The present invention calculates the syrup dispensing time from the syrup dispensing amount per unit time for each syrup viscosity and the syrup discharging amount by setting information corresponding to the syrup viscosity using the method described above. . That is, the syrup dispensing time is changed based on information on the syrup viscosity, which has not been taken into consideration so far. For example, in the case of low-viscosity syrup, the discharge time is lengthened by reducing the discharge amount per unit time, thereby making it possible to finely adjust the flow rate and reducing fluctuations in the flow rate.

EXAMPLE Hereinafter, a method for setting a beverage discharge amount of a vending machine according to an example of the present invention will be described with reference to the drawings.

Each piece of information is set using a digital switch or numeric keypad switch provided on the vending machine. Here, the amount of carbonated water discharged per unit time C! 1 (cc/sec) and the discharge amount of cold water per unit time d1 (cc/sec)
, the discharge amount e (cc/sec) of multiple types of syrup per unit time corresponding to the syrup viscosity n and the fixed time a1 (sec) that determines the start of syrup discharge are determined by the microcomputer's RO.
It shall be written in M. Next, in step 102, the microcomputer calculates the amount of syrup discharged per unit time corresponding to the syrup viscosity n - (cc/sec) as RO.
Select within M. At this time, the syrup viscosity n1 is the amount of syrup discharged per unit time e (cc/sec), and the syrup n2 is e
2 (cc/sec) corresponds to n3, and e3 (cc/sec) corresponds to n3.

As mentioned above, the amount of syrup discharged per unit time e(c
c/sec), the discharge amounts of syrup, carbonated water, and cold water are calculated in step 103.

By calculating y2=xIX71, the syrup discharge amount y2 (
cc), CI=! The carbonated water discharge amount C1 (CC) is calculated by calculating 1xf(zl), and the cold water discharge amount d1 (cc) is calculated by calculating d1=x1-72-cl. Also f(zl)(1)
is the total amount x1 (cc) derived from the carbonic acid concentration z1
This is the mixing ratio of carbonated water to carbonated water.

Next, in step 104, TS=
Calculate y2/e, calculate syrup discharge time Ts■), and calculate TC=C1/C2 from carbonated water discharge amount a1 (cc) and carbonated water discharge amount c2 (cc/sec) per unit time. Calculate the carbonated water discharge time T c (seconds), and calculate the cold water discharge amount d1 (ω) and the cold water discharge amount d per unit time.
2 (cc/sec), TH=d1/d2 is calculated to calculate the cold water discharge time TH (sec).

Syrup discharge time Ts calculated in step 104 above

In step 105, the second
The microcomputer described above controls the raw materials according to the time chart shown in the figure.

In the above embodiment, the delay time from the start of dispensing dilution water to the start of dispensing syrup was fixed, but if the preceding time from the end of dispensing syrup to the end of dispensing diluting water was fixed, both the delay time and the preceding time could be changed according to the syrup viscosity. Similar results can be obtained by varying the value.

The present invention, which is more than the effect of the invention, is directed to the discharge amount per unit time of dilution water such as carbonated water or carbonated water and cold water or cold water or hot water to dilute the syrup, and the discharge amount per unit time of multiple types of syrups. The amount and the delay time from the start of dispensing of dilution water to the start of dispensing of syrup are memorized in advance, and values corresponding to the total volume of beverages to be sold, the mixing ratio of syrup to the total volume, carbonic acid concentration, and syrup viscosity are respectively arbitrarily stored. First, in response to the specified value corresponding to the syrup viscosity, a certain discharge amount is selected from among the discharge amounts of multiple types of syrup per unit time, and the syrup amount is calculated from the mixing ratio of syrup to the total amount. Then, calculate the amount of carbonated water from the total amount and the carbonic acid concentration, and calculate the total amount.

Calculating the amount of cold water from the amount of syrup and the amount of carbonated water,
By performing a beverage discharge setting method for a vending machine that calculates the discharge time from each discharge amount per unit time, it is possible to finely adjust the flow rate even for syrups of various viscosities. It is possible to provide a vending machine with good reeds and less fluctuation in flow rate.
