It may be required to optionally choose between adding sugar only, adding cream only, or adding cream and sugar.

Problems to be solved by the invention This type of vending machine is, for example,
As described in Publication No. 69390 (Japanese Patent Application No. 143516/1983), in this case, conventionally, the push button switch was used for American coffee and standard coffee, respectively, as shown in Figure 1.
One push button switch is provided for individually instructing black, cream with sugar, cream with sugar, and cream with sugar. Therefore, it is necessary to provide eight pushbutton switches, which increases the space for installing the pushbuttons, and also has the drawback that the operator cannot quickly select the pushbuttons.

The present invention has been developed to eliminate the above-mentioned drawbacks and aims to provide a vending machine that can sell coffee in various combinations.

Means for Solving the Problems The vending machine of the present invention has a first push button switch that specifies coffee of a first concentration, a second push button switch that specifies coffee of a second concentration, and a vending machine that specifies contamination with sugar. a third pushbutton switch for specifying mixing of cream, a fourth pushbutton switch for specifying cream mixing, and first to fourth memories provided for each pushbutton switch to remember that the corresponding pushbutton switch has been turned on. A coffee bend motor for carrying out the coffee ingredients, a cream bend motor for carrying out the cream, a sugar bend motor for carrying out the sugar, and the contents of the first to fourth memory devices are read out and the contents are set. The above coffee bend motor, cream bend motor,
The present invention is characterized by comprising a control device that outputs a signal for driving a sugar bending motor.

Function For example, when the second and fourth pushbutton switches are turned on, the memory contents of the first to fourth memory devices become "0101," and the control device reads the contents of this memory device and controls the coffee bend motor. A signal is output to drive the sugar bend motor for a predetermined period of time, and as a result, standard coffee with sugar is sold.

For example, when the first, third, and fourth pushbutton switches are turned on, the memory content of the storage means becomes "0111" and it is determined that it is standard coffee with cream and sugar, and standard coffee with cream and sugar is sold. Ru.

Embodiment An embodiment of the present invention will be described below with reference to the drawings.

As shown in FIG. 2, for the sale of coffee, there is a first push button switch 1 on the face of the vending machine that specifies American coffee, a second push button switch 2 that specifies standard coffee,
Only four pushbuttons are provided: a third pushbutton switch 3 for specifying the addition of cream, and a fourth pushbutton switch 4 for specifying the addition of sugar.

As shown in FIG. 3, each pushbutton switch 1, 2, 3, 4 is connected to a microcomputer 10 as a control device for controlling sales of the vending machine.

The microcomputer 10 has flags 11, 12, 13, 1 as storage means for storing that each pushbutton switch 1, 2, 3, 4 is turned on.
4 is provided.

In FIG. 3, in addition to the coffee-related pushbutton switches described above, a pushbutton switch 5 for instructing the sale of other products, such as cocoa, is also connected to the microcomputer 10.

A coin detection mechanism 20 is connected to the microcomputer 10, which detects coins inserted into the vending machine and generates a bend signal when a predetermined amount or more is inserted, and a coffee bend motor 31 is connected to the output terminal. cream bend motor 32;
A sugar bend motor 33 is connected. As shown in FIG.
35 and 36, and when each bend motor rotates, an appropriate shutter corresponding to the bend motor is opened, and an amount of coffee, cream, and sugar corresponding to the opening time of the shutter is released into the raw material shutter 37. .

In addition, in Fig. 4, 38 is a mixing bowl,
39 is a cup, 40 is a hot water storage tank, and 41 is a coffee hot water sales valve.

In FIG. 3, a push button switch 5 for specifying a product other than coffee, such as cocoa, and a cocoa bend motor 50 are also connected to the microcomputer 10.

The microcomputer 10 is equipped with a program to drive each bend motor according to a specified product, feed a predetermined material into a mixing bowl 38, and perform automatic vending. , is equipped with a program shown in FIG. 5 that determines which bend motor to drive.

That is, in step S2, input data such as a signal from the coin detection mechanism 20 and a switch (not shown) that detects the presence or absence of raw materials in each tank are read, and in step S3 it is determined whether each raw material is sold out. If the coins are not sold out, the process proceeds to step S4, and the presence or absence of a bend signal from the coin detection mechanism 20 is checked. If the specified amount has been deposited, the step
At S5, the indicator light indicating that the product is ready for sale is lit in response to the bend signal.

Next, in step S6, each pushbutton switch 1,
The inputs from 2, 3, and 4 are read, and it is determined in step S7 whether push button switch 1 or 2 for coffee has been selected. If coffee is selected, the process advances to step S8, where a flag corresponding to the selected pushbutton switch is set. For example, if American coffee with sugar is selected (pushbutton switches 1 and 4 are on), flags 11 and 1
4 becomes "1".

The process then proceeds to step S9, where a signal from a switch (not shown) indicating whether or not the raw material has been output is read, and the process proceeds to step S10, where it is determined whether or not the raw material has been output. If the raw materials have not yet been output, the process advances to step S15, where the amount of coffee raw materials is set based on the state of the flag, and the bend motor for the raw materials whose flags are set to "1" is driven to release, for example, coffee and sugar. It releases hot water and sells coffee with sugar.

If it has been after raw materials have been output, proceed to step S11 and read whether or not a product has been selected; if not, return to step S9; if it has been selected, proceed to step S12, and press the selected pushbutton switch. Set the corresponding flag and return to step S9.

In the vending machine having the above-mentioned configuration, if a user wants to specify American coffee black, only the push button switch 1 is turned on after inserting a predetermined amount of money. At this time, only flag 11 is turned on, and the status of each flag becomes "1000", and it is determined that the coffee is American coffee and black.

Further, when pushbutton switches 1 and 3 are turned on, the content of the flag becomes "1010" and it is determined that the coffee is American coffee with cream.

Further, when pushbutton switches 1, 3, and 4 are turned on, the content of the flag becomes "1011" and it is determined that the coffee is American coffee with cream and sugar.

Next, when only the push button switch 2 is turned on, the flag becomes "0100" and it is determined that the coffee is standard coffee black.

When push button switches 2 and 3 are turned on,
The flag is "0110" and it is determined that it is standard coffee with cream.

When pushbutton switches 2 and 4 are turned on, the flag becomes "0101" and it is determined that the coffee is standard coffee with sugar.

When pushbutton switches 2, 3, and 4 are turned on, the flag becomes "0111" and it is determined that the coffee is standard coffee with cream and sugar.

Then, according to each determination result, each of the bend motors 31 to 33 is individually driven and controlled for a predetermined period of time, and a predetermined coffee is sold.

Effects of the Invention As detailed above, according to this invention, eight types of coffee can be sold using four pushbutton switches, so the installation space for the pushbuttons is halved compared to the conventional one. Therefore, the space on the vending machine panel can be saved and the vending machine can be made smaller, and the number of push buttons can be reduced, so that customers can quickly select the type of coffee.
