Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a beverage liquid dispensing device that is applied to, for example, a coffee vending machine that sells coffee by discharging coffee raw materials and pickles.

[Technical Background of the Invention] Conventionally, for example, a coffee vending machine has been provided with a canister containing coffee raw materials, and a water boiling tank, and the vending machine is provided with a canister that stores coffee ingredients, and is provided with a water boiling tank. The motor operates for a predetermined time to release a predetermined amount of coffee ingredients, and the N magnetic valve installed in the water boiling tank operates for a predetermined time to release a predetermined amount of hot water, and the released hot water and coffee ingredients are combined. It is known to obtain and sell coffee by mixing it or feeding it to a brewing mechanism.

[Problems with the Background Art] By the way, a motor attached to a canister, etc. has a coiled spring attached to its rotating shaft, and as the motor rotates, the spring rotates, discharging the coffee ingredients in the canister to the outside. It is configured to be extruded and released. Therefore, the amount of coffee material discharged from the canister to the outside varies depending not only on the operating time of the machine, but also on mechanical properties such as the diameter and pitch of the spring, and the specific gravity of the coffee material. However, in the past, the release amount of coffee ingredients was set only based on the operating time of the motor, completely ignoring mechanical differences and the specific gravity of the coffee ingredients. In order to make the discharge amount the same, the discharge time must be made the same, and therefore there is a problem in that it is not possible to reliably match the discharge amounts of the raw material from each canister. Also,
When setting the release time, it is necessary to release agricultural raw materials equivalent to the amount released in one sale and measure the time, which poses a problem in that setting work is time consuming and troublesome.

[Purpose of the Invention] This invention was devised to solve such a problem, and when the amount of raw material released from a plurality of raw material supply mechanisms is made the same, it is possible to ensure that the amount of raw material released is the same. To provide a beverage liquid dispensing device which can easily perform setting work for determining the discharge amount.

[Summary of the Invention] The present invention operates a raw material supply mechanism selected from a plurality of raw materials by operating a selection switch for a preset predetermined time to release raw materials, and also operates a water or hot water supply mechanism for a preset predetermined time. In a beverage liquid discharging device that discharges water or hot water to the outside by operating over a period of time, there is a reference time memory storing reference time data set corresponding to each raw material supply mechanism, and each raw material supply mechanism. A discharge amount memory stores data on the actual discharge amount to be finally discharged from the source, a discharge time memory stores the actual discharge time of each raw material supply mechanism, and a keyboard are provided. The operation is performed based on the corresponding reference time data stored in the memory, and the corresponding actual release amount data in the release amount memory, the corresponding reference time data in the reference time memory, and each raw material supply mechanism input from the keyboard are set to the reference time. The actual discharge time required for each raw material supply mechanism to discharge the actual discharge bottle is calculated based on the raw material discharge amount data during operation, and each actual discharge time determined by this calculation is stored in the discharge time memory. After each actual release time is stored in the release time memory, the corresponding raw material supply mechanism is operated based on the actual release time.

The discharge time memory 114 stores one actual discharge time data for each of the canisters 39 to 45 and one actual discharge time data for each of the solenoid valves 22 to 24, which are obtained by a setting operation described later. It has become.

The actual release time data set in the release time memory 114 is addressed by a code, for example, so that it can be read out.

The CP Ll 101 performs various control processes based on program data in the ROM 102. When setting actual release time data in the release time memory 14, the process shown in FIG. 6 is performed. First, specify the release time setting mode. This mode specification is made according to the table below. For example, if you input 17" rOJ on the numeric keypad and operate the input key, "70" mode will be specified and regular A will be selected.
A release time setting mode for coffee raw materials is specified.

The table next shows the counter 115 and each register 116 of A%BSC.
．． Clear 117.118. In this state, it waits for key input. When the operation key is input, the reference time corresponding to the specified mode is read from the reference time memory 112, and the corresponding load is operated based on the reference time. For example, in the "70" mode, the raw material discharge motor 82 of the regular A coffee canister 39 is operated for the standard time.

It then waits for key input again. At this time, the operator measures the amount of raw material or hot water released by the operation of the load. When the reference release amount measured in this state is input using the numeric keypad and the input key, the reference release amount data is added and input to the A register 116. Then, the counter 115 is incremented by one. As long as the value of this counter 115 does not reach "5", the routine returns to waiting for an operation key input. Through this process, the total value obtained by measuring the standard release amount five times is stored in the A register 116. When the value of the counter 115 becomes "5", the contents of the A register 116 are divided by 5,
Calculate the average value of the reference emission amount and store the result in B register 11.
Store in 1. Next, the reference time read from the reference time memory 112 is divided by the contents of the B register 117 to obtain the time per unit emitted amount, and the result is cleared in the A register 116 and stored there.

Next, the actual discharge amount data of raw materials and hot water corresponding to the designated mode is read from the discharge amount memory 113 and the B register 11
Clear 7 and store it there. Next, A register 116
and the contents of the 8 register 117 to determine the actual release time and store the result in the C register 118. Finally, the contents of the C register 118 are stored at a predetermined address in the release time memory 114. In this way, the actual release time setting for one raw material or hot water corresponding to one mode is completed. By performing such setting processing for mode "70" and port "79" shown in the table, the release time setting processing is completed.

Further, the CPU 101 performs the processing shown in FIG. 7 when performing normal sales. That is,
While the on-sale indicator lamp 2 is lit, press the coin mechanism 8.
When a predetermined amount of coins are inserted into the slot 7 and the selection switch 8 is operated (in this case, if the function switch 9 is operated in advance, the amount of hot water will increase or decrease, the amount of sugar will increase or decrease, the amount of cream will increase or decrease). , no sugar is set), controls the coin mechanism 87 to accept coins,
Have them return change, etc. Next, the load corresponding to the sales product is identified. This determines the address for reading desired actual release time data from the release time memory 114 based on signals from the funtion switch 9 and the selection switch 8. Then, based on this address, necessary actual emission time data is read from the emission time memory 114. Next, the motor and valve are driven and controlled for a predetermined period of time based on the read actual discharge time data, and the piston 38
A desired beverage liquid is supplied to the cup 53 set in the vending outlet 11 by driving and controlling the pump 35 and the procon pump 35. In this way, one beverage sale operation is completed and the next sale is made to wait.

In the embodiment of the present invention having such a configuration, regular A regular B regular C is stored in the reference time memory 112 in advance.
The reference times are set for each coffee raw material, instant coffee raw material, sugar raw material, cream raw material, cocoa raw material, hot water for regular coffee, pouring water for instant coffee, and hot water for cocoa. Regular B and regular C coffee ingredients,
Instant coffee raw materials, sugar raw materials, cream raw materials,
The actual release amounts of cocoa raw materials, hot water for regular coffee, thirst for instant coffee, and hot water for cocoa are set. Then, by operating a key, a mode is designated for which raw material and water the discharge time is to be set, and the motor and valve for discharging the designated raw material or hot water are operated based on the reference time read from the reference time memory 112.

The raw materials and hot water released at this time are measured. Then, the measured release amount is input by key as the reference release amount. By repeating this operation five times, the average reference release amount is determined. Then, from the average standard discharge amount, the read reference time, and the corresponding actual discharge amount set in the discharge amount memory 113, the actual discharge time during which the motor and valve actually operate in one sale is determined, The release time is set in the release time memory 114. When the setting of the actual discharge time data in the discharge time memory 114 is completed, it becomes possible to sell the beverage, and at the time of sale, all motors and valves are operated based on the data set in the discharge time memory 114. .

In this way, by first discharging and measuring the raw material or hot water based on the standard time, and then inputting the measured standard discharge amount using the key, you can calculate the actual discharge amount that you want to release, the reference time, and the key-input standard discharge amount. Since the operation time of the motor and valve that operate in one sales operation is determined based on the There are mechanical differences in the solenoid valves that control the release, so even if the amount of raw material or hot water discharged per unit time is different, the actual discharge time is determined according to the difference. If you want to make the same release amount at the time of sale, you can surely match the release amount. Moreover, by setting the standard release time short, the time required to measure the standard release amount can be shortened, and there is no need to release and measure the amount to be sold at one time as in the past, and the release amount The setting work can be done easily. In addition, the standard release amount for one raw material or hot water is measured 5 times and the average is calculated, and the actual release time is set based on that, so the actual release time can be set with high accuracy. .

In the above embodiment, the measurement of the reference release amount was repeated five times, but the number of times is not particularly limited and may be one time depending on the case.

Although this embodiment has been described in which the present invention is applied to a vending machine, the present invention is not necessarily limited to this, and can also be applied to a machine that does not require the insertion of money.

[Effects of the Invention] As detailed above, according to the present invention, when the amounts of raw materials discharged from a plurality of raw material supply mechanisms are made the same, the discharge amounts can be reliably made the same, and the discharge It is possible to provide a beverage liquid dispensing device that allows easy setting work for determining the amount.
