Description

DETAILED DESCRIPTION OF THE INVENTION This invention provides a vending machine that combines and mixes a plurality of raw materials and selects and sells various types of coffee using a selection switch. There may be times when you want to change to coffee.

However, in conventional relay-controlled vending machines, when the selection switch for one product A is turned on after inserting a predetermined amount of money, the relay
A is self-held, and automatic sales operations such as carrying out the raw materials for product A are performed by the signal of the contact of relay XA. Once product A is selected, the self-holding of the corresponding relay XA is continued. As it says (/C),
-i, Once a product was selected, it was not possible to change to another product.

This invention was made in order to eliminate the above-mentioned drawbacks, and even after a product has been selected, it is possible to change the selected product until the raw materials begin to be delivered. The purpose of this invention is to provide a vending machine that is easy for people to use.

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

In FIG. 1, l is a CPU (central processing unit) of the vending machine, and for example, a microcomputer is used. Reference numeral 2 denotes a coin detection mechanism that detects coins inserted into the vending machine, and outputs a signal to an output terminal corresponding to the amount of money inserted.

The output terminal of the coin detection mechanism 2 is connected to the CPUI.

Ba, 8b+..., 3n are pushbutton switches for selecting various products, and each is connected to the CPUI. For example, pushbogunnitch 8a indicates coffee, 3b indicates cream, and 8C indicates sugar.

A register 1a in the cpul is provided with an area for storing the product specified by the push button switch, and during a sales operation, a signal indicating the product is written in the corresponding nutage of the output register IX.

1' Furthermore, it takes about 2.5 to 8 seconds for the CPU to discharge the raw materials for coffee from the raw material tank after the product is selected and the sales operation starts. A timer T1 is provided to measure time.

4"+ 4b+..., 4n are relays that drive the motor that discharges the raw materials of the product to be sold. For example, 4a
Assume that 4b is for coffee, 4b is for cream, and 4C is for sugar.

FIG. 2 shows an example of a program for controlling the vending machine shown in FIG. 1, and this program is stored in cpuIIL. Similar to known vending machines, cpul has control functions required to sell various designated products, such as comparing the amount of money inserted with the product price set on the Ply 7 board (not shown). and a function that generates a signal indicating that the product is ready for sale (sellable signal), a lamp that indicates that the product is ready for sale, a function that sets the discharge time of raw materials for a specified product, and discharges a predetermined amount of raw materials, etc. However, since it is the same as a known one, the explanation will be omitted.

In the above-mentioned vending machine, initial settings, reading of input data, whether or not the item is sold out, whether there is a sell signal, etc. [1- Performed in steps s1 to S8, and turning on a predetermined vending lamp and , if the product has been selected, the process advances to step S7 and a sales operation is started.

Next, in step S8, the input is read, and in S9, the timer TI is
Start. In step 810, it is determined whether or not the set time of the timer TI has elapsed, and if the time has not elapsed, that is, if the raw material has not yet been discharged, the process proceeds to step Sll.
It is checked whether input has been made from the product selection push button, and if the selection push button signal has been input, the process proceeds to step s12, where it is determined whether the input amount is valid, and if it is valid. , proceed to step 51B and register I
Rewrite X with the product corresponding to the selection pushbutton read out as described above. Also, step 5
14, the lighting of the sales lamp will also be changed.

The rewritten products are then sold.

Next, the operation will be explained.

For example, a predetermined amount of money is inserted, and then black coffee (coffee without sugar or cream) is dispensed.
When designated by the pushbutton switch 3a, a signal 1 is written to the position indicating black coffee in the register 1x. Then, the indicator lamp indicating black coffee lights up.

On the other hand, timer 'r1 is activated and sales operations such as discharging the cup and calculating change are started. During this time, steps S2 to 516 are repeated.

If the push button switch 2a'2 for cream is turned on to change from black coffee to coffee with cream before the set time limit of timer Tl elapses, a signal indicating the selection of cream is written to the corresponding position of register IR. . Then, in step Sll, it is determined that the selection input is valid, and in step 512, it is determined whether correction of change etc. is necessary. If correction is not necessary, step 513
Go to the register IX and place the signal ゞl in the position indicating the cream.
' is written. Also, the cream sales lamp lights up.

If the time TI elapses without any changes to the product selection,
If NO is determined in step 510, the process proceeds to Nutetsubu S15, where sales processing is performed, and relay 43 for coffee and relay 4b for cream are processed according to the contents of register IX.
is turned on as appropriate, coffee and cream are discharged, and coffee with cream is sold.

If, for example, the push button switch 4C for sugar is turned on after the above-mentioned time Tl has elapsed, the product will not be changed and coffee with cream and no sugar will be sold.

Furthermore, even if the push button switch is turned on to change the type of product before time T1 has elapsed, if the price of the product is different from the price of the previously specified product, the product cannot be changed.

As described in detail above, the present invention provides a vending machine that can select and sell multiple types of products.
Since the product selection can be changed until the start of discharging raw materials for that product, it is possible to provide vending machines that are easy to use on a 1.1:1 basis for each customer.
