Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a vending machine that mixes and sells a plurality of powder raw materials, and in particular, the reception of the increase/decrease switch when increasing or decreasing the powder raw materials according to preference is related to time.

Conventional technology In recent years, vending machines that mix and sell multiple powder raw materials have
It is required to be able to increase or decrease the amount of powdered raw materials in sales products according to customer preference. Currently, in conventional vending machines, the time required to accept the increase/decrease switch for each raw material is either a fixed period of time after the start of raw material delivery (any time from the start of raw material transport until the amount reaches the reduced amount) or a predetermined time for each raw material. In this case, no increase switch will be accepted, and the lamps indicating acceptance will go out when each increase/decrease switch is no longer accepted.

Problems to be Solved by the Invention However, with the method described above, there is no problem when it comes to weight loss, but when it comes to weight increase, it is possible to accept a weight loss switch even after the deadline However, there is a drawback that the actual acceptance time for increase/decrease is shorter than the possible time for increasing/decreasing the quantity.

Therefore, in view of the above-mentioned drawbacks of the conventional method, the present invention aims to lengthen the time it takes to accept the increase/decrease switch for each powder raw material.

Means for Solving the Problems Therefore, in view of the above object, the present invention separates the reception time for the increase/decrease switch for each powder raw material for increase and decrease, and first disables acceptance of the decrease switch and turns off the decrease lamp at the same time. Then, the increase switch is not accepted and the increase lamp is turned off at the same time.

Operation Therefore, since each increase/decrease switch is accepted separately, the time required to accept each switch is extended to the limit of possible reception time, so the acceptance time for each increase/decrease switch is long.

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

In FIG. 1, 1 is a microcomputer (hereinafter referred to as CPU) that performs input/output signal processing, and 2 is a coin detection mechanism that detects coins inserted into the vending machine and generates a signal representing the amount of money inserted. It is. 3a to 3n are raw material setting switches for setting the amount of raw materials to be discharged and the total amount of raw materials;
A to 4n are switches that indicate the products to be sold, including various increase/decrease switches. Further, 6a to 5n are increase/decrease lamps that indicate whether the raw materials of the product to be sold can be increased or decreased, and 5o to 52 are product sales ready lamps.

Numerals 6a to 6d are raw material discharge relays for respectively driving motors (all of which will be described later) for conveying various raw materials. 7a is a solenoid valve for discharging hot water; 7b is a relay for separately driving a motor for blending a mixing ball (both will be described later); and 2.3a to 3n are connected to the input port of the CPU 1.

4a to 4n are connected, and the output port has sa
~sn, 6a-6d, 7a-yb are connected.

There is a RAM 5 in the CPU 1, and a raw material setting switch 3a.
From 3n, the amount of raw materials for each product is written for each 1-force increase, that is, in the case of coffee, the amount of coffee raw materials, the amount of cream, and the amount of sugar are written separately, and the increase and decrease of each raw material is written. written.

Furthermore, the price of each product is also written in the RAM s. FIG. 2 is a diagram showing a supply system for raw materials, etc. in this type of vending machine, in which 10 is a water tank;
1 is a heater, 12a is a raw material tank for coffee, 12b
is a raw material tank for cream, 12c is a raw material tank for sugar, 12d is a raw material tank for cocoa, 13a to 13
d is a raw material discharge motor provided in each raw material tank, and as each motor rotates, the discharge port opens and a predetermined raw material is discharged into the chute 14.15. Depending on the length of time the material is present, the amount of raw material released is controlled.

Note that 16 is a mixing bowl, and 17 is a cup for receiving drinks such as coffee and cocoa to be sold. The tap water is then supplied to the water tank 10 via the water intake valve 18. In addition, 19 is a solenoid valve for discharging hot water, and chute 14.15
supply hot water.

For convenience of explanation, for example, the relay 6a is the coffee motor 13a1, 6b is the cream motor 13b, 6c.
6d is the motor 13 for sugar, and 6d is the motor 13 for cocoa.
d and 7a are electromagnetic valves 19.7b and 19.7b are relays for controlling the mixing pole.

Next, the operation of the vending machine having the above configuration will be explained.

First, it is assumed that a predetermined amount of each of the raw materials shown in the above configuration is stored in the raw material tanks 12a to 12d. At this time, the amount of raw materials contained in each of the raw material tanks 12a to 12d is written to the RAM 5 by the raw material setting switches 3a to 3n, and in the same manner, the raw material setting switches 3a to 3d are written.
, the amount to be carried out when selling each raw material once (that is, the operating time of the motors 13a to 13d) and the increase/decrease rate of each raw material are also written.

Now, when a customer inserts, for example, 100 yen into the vending machine, the coin detection mechanism 2 sends a signal corresponding to 100 yen to the CP.
Send it to U1 (Figure 3, 5 top 1).

The CPU 1 determines the products that can be sold based on this input amount, and displays one of the sales ready lamps 15n to 16Z for the corresponding products (FIG. 3, step 5).

By lighting the sales ready lamps 15n to 15z, the customer knows that a predetermined product such as coffee is available for sale, and turns on the switch 4a corresponding to the sales product such as real coffee.
When any one of 4n is turned on (Fig. 3, 5)
tep2) CPU 1 cigarette switch 4a to 4
n is read, and it is detected that an instruction has been given to sell any one product such as hot coffee. If hot coffee is selected, the amount of coffee ingredients, sugar amount, cream amount, and increase/decrease rate are stored in RAM.
8, and calculate the time corresponding to the standard amount of raw material to be discharged for each raw material, the time when the amount is increased, and the time when the amount is decreased (Fig. 3, top 4), and When the motor corresponding to 13a to 13d is turned on and a predetermined motor 13a to 13d is driven, step 7 is started and the increase/decrease lamp for each raw material (sugar and cream in this example) is turned on. ),
Discharging a predetermined amount of coffee raw materials, cream, and sugar from each predetermined tank 12a to 12d is started.

Next, when the output amount of sugar or cream reaches the amount when the amount is reduced (Fig. 3, top 6), the input of each reduction switch (
dReception will no longer be accepted, and each weight loss lamp will be turned off (Fig. 3, 5).
step 7). Furthermore, when the standard discharge amount is reached (Fig. 3, 5
tep2) Disable input to each increase switch and turn off the increase switch (top 9 in FIG. 3).

When the standard amount of each raw material has been discharged, the relays 6a to 6d that have been turned on are turned off to complete the raw material discharge.

Similarly, the relay 7a is turned on and the electromagnetic valve 19 for draining hot water is opened to discharge a predetermined amount of hot water from the water tank 10 to the cup 17. For example, when the temperature of the water tank 1° falls below a predetermined temperature, the heater 11 is energized and heats the water in the water tank 1o. When the water temperature in the water tank 10 rises to a predetermined temperature, power supply to the heater 11 is stopped. Further, when the water in the water tank 10 becomes less than a predetermined amount, the water intake valve 18 opens and water is supplied to the water tank 1o, and when the water becomes less than a predetermined amount, the water intake valve 18 is closed.

As mentioned above, when accepting the increase/decrease switch in product sales, the time is set separately for increase and decrease, and by accepting the acceptance until the time when it is possible to increase or decrease the amount of each raw material to be exported, the time for increase/decrease selection can be extended, allowing you to select the product of your choice. This has the effect of giving sufficient time for selection.

Effects of the Invention As is clear from the above explanation, the present invention provides a vending machine that mixes and sells powdered raw materials, which can increase or decrease the amount of powdered raw materials that can be increased or decreased among the powdered raw materials to be taken out when selling products. The quantity switch acceptance time is set separately for quantity increase and quantity reduction, and the quantity reduction switch is first discontinued and the quantity reduction lamp is turned off. The time at that time is set as the unloading time when the weight reduction switch that enables weight reduction is pressed, and then the weight increase switch is not accepted and the weight increase lamp is turned off. The time at that time is until the time when the standard amount, which can be increased, is taken out.

As a result, it takes a long time to accept an increase/decrease switch in product sales, which has the effect of providing sufficient time for selecting a desired product.
