The present invention relates to a raw material dispensing apparatus of a coffee vending machine, and more particularly, to a raw material dispensing apparatus of a coffee vending machine in which undissolved coffee, rim chunks, etc. are not found in a coffee cup during coffee sales.

As is well known, in using a conventional coffee vending machine (hereinafter referred to as a vending machine), we find a phenomenon in which a mass of undissolved raw material (coffee or prim) floats in a discharged coffee cup. This phenomenon is because the raw material outlet of the material container becomes wet due to water vapor generated during the mixing of hot water with the raw material during coffee sales, and the raw material exposed to air becomes solidified over time. In this case, when the solidified raw material is sold to the coffee cup, the user finds the solidified raw material mass that is not dissolved in the coffee cup, which is hygienic and dirty, and in a severe case, the passage is blocked by the mass. It can also cause a vending machine failure.

Therefore, in order to solve the above problems, a piercing part was provided at the raw material outlet of the raw material container so that water vapor coming up during the mixing of the raw materials went out through the piercing part, but there may be a difference in the degree, but the raw material outlet after the passage of time Solidification of the surrounding raw materials also occurred.

The present invention has been made to solve the above problems, an object of the present invention is to discharge the solidified raw material to a place other than a paper cup when selling coffee, and only the pure powdered raw material is combined with hot water to be discharged into a paper cup An object of the present invention is to provide a raw material dispensing device for a vending machine.

In order to achieve the above object, the present invention provides three discharge chambers for each feed container outlet, one outlet of the three sides connects to the drain through the drainage pipe, and the other outlet of the three discharges to the raw material discharge pipe. A three-way drive unit connected to the three sides to open a passage so that a flow path is formed in the discharge portion and the drainage pipe, and the passage is opened so that a flow path is formed in the discharge portion and the raw material discharge pipe when the three-way operation is stopped; In the case of coffee sales, if the coffee sales activity has not been performed for a certain time, the microcomputer is provided with a microcomputer that drives the three-way side for a predetermined time and drives the solidified raw materials through the drainage pipe at the same time as driving the material discharge motor of the corresponding material container. There is this.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 is a schematic configuration diagram of a raw material container 1 according to the present invention, which includes a mixed impeller 2 for driving a diaphragm not shown in a rotating operation to prevent freezing of raw materials and to uniformly discharge the raw materials, and to rotate them. A raw material discharging gear 3 for discharging the raw material to the discharge port 5, a motor M for rotating the raw material discharging gear 3, and a groove for discharging water vapor generated during raw material mixing to the outside. In the conventional raw material container 1 structure which consists of the piercing part 4 which cuts out, this invention provides a 3-way valve in the said discharge part 5, and this 3-way valve is provided. One end of the drainage pipe (6) is connected to the other outlet is connected to the raw material discharge pipe (7) when the three-way (V) is not operated when the drainage pipe (6) side is closed, the raw material discharge pipe ( 7) The side is opened so that the raw material is discharged through the discharge section (5) → three-way (V) → raw material discharge pipe (7), and drained when the three-way (V) is driven The furnace pipe 7 side is opened and the raw material discharge pipe 7 side is closed so that the raw material is discharged through the discharge part 5 → three-way side V → drainage pipe 6.

FIG. 2 schematically shows the overall internal structure of the vending machine to which the present invention is applied, and includes raw materials containers 1, 1a and 1b corresponding to coffee, prim, sugar and the like, and respective raw materials containers 1, 1a and 1b. The three-way (V) corresponding to the), the raw material discharge pipe (7) for guiding the raw material discharged through the three-way (V), and the solid raw material discharged through the three-way (V) drainage ( 15) to the drain pipe (6), hot water tank (8) containing hot water, a hot water valve (10) for controlling the input of hot water, and a hot water thrower for sending the hot water discharged to the mixing vessel (12) A discharge pipe 9, a guide pipe 11 for collecting raw materials discharged through the raw material discharge pipe 7, a raw material discharged through the guide pipe 11, and a discharge through the hot water discharge pipe 9. It consists of a mixing container 12 for mixing hot water, a paper cup 13 for receiving raw materials (coffee) mixed in the mixing container 12, and a pedestal 14.

Figure 3 shows a control circuit for driving the device according to the present invention configured as described above, the motor drive unit 21 for driving the raw material discharge motor (M) is a predetermined predetermined microcomputer 20 at the time of coffee sales When the motor M is driven only for a period of time, the microcomputer 20 outputs a low signal to the motor driver 21. The output signal is then inverted through the inverter IV1 to turn on the transistor Q. The motor M to which the voltage V3: 24V is applied to the motor M through the negative resistance thermistor NTC is driven. After the predetermined time has elapsed, when the microcomputer 20 cuts off the output, the motor M is stopped and the discharging of the raw materials is stopped.

In addition, 22 is a three-sided driving unit. When the microcomputer 20 outputs a low signal to the three-sided driving unit 22, the output low signal is inverted through the inverter IV2 and the relay RY is energized to supply power. (AC) is applied to the three-sided (V) to operate the three-sided (V). Therefore, as described above, the drainage pipe 7 side is opened, and the raw material discharge pipe 7 side is closed so that the raw material is discharged through the discharge part 5 → three-way side V → drainage pipe 6.

The key input unit 23 includes a plurality of selection buttons to select a product. The microcomputer 20 recognizes the selected beverage by a specific key input according to the product (coffee) selection.

The coin device 24 generates a price signal for the coin put by the user and inputs it to the microcomputer 20 to independently perform functions such as change calculation, amount reduction and change of the change.

The hot water valve driving unit 25 controls the opening and closing of the hot water valve 10, and the display unit 26 informs the merchandise in the marketable state by turning on or off the lamp outside the vending machine.

In addition, the motor driving unit 21 shows only the driving of a single motor (M) for a single raw material cylinder (1), but in reality there are a plurality of motors for a plurality of raw material cylinders, There are also a large number of trilobites.

Reference numeral V1 denotes a 5 volt DC voltage, and V2 denotes a 12 volt DC voltage.

The operation and effects of the present invention configured as described above will be described with reference to the operation flowchart of FIG.

First, the power is supplied to the device, the microcomputer 20 enters the standby state (step 100), detects whether the price signal is input through the coin device 24 (step 101), and the selling price of the displayed coffee. When the above signal is detected, if it becomes available for sale soon, the beverage signal selected through the key input unit 23 is detected (step 102). The case where the key input here is milk coffee (coffee + cream + sugar) is demonstrated as an example. When the milk coffee is selected, it is determined whether the predetermined time (eg, one hour) has elapsed in the motor driving step 103 corresponding to each raw material (step 104). This is the time from the stop of the motor until the sale behavior, or the motor reactivation, which is a time sufficient for the raw material to solidify. Therefore, if one hour has not elapsed since the selling operation in step 104, the process jumps to step 109 to maintain the three-way side V in a stopped state (step 109), and drives the motor and the hot water valve 10 (step 110). After normal sales, the sales time of the motor is cleared (step 111), and the resale time is counted (step 12).

However, if the motor (for example, a coffee raw material motor) has passed one hour after the selling operation in step 104, the microcomputer 20 starts the set (step 105) and counts for three seconds, and sets the three directions (V). Drive the solidified coffee raw material into the discharge part (5) → three-way (V) → drainage pipe (60 through the basin 15), prohibit the release of other raw materials (prime, milk) and hot water (Step 107) and after 3 seconds (108 steps), the step 109 to stop the three-way (V), 110 steps to start the normal discharge operation by starting the discharge of other raw materials (prime, milk) and hot water; Steps 111 and 112 described above are sequentially performed.

As described above, the present invention solves the conventional problem of discharging the solidified raw material mass into the paper cup as it is, thereby preventing clogging of the raw material discharge of the vending machine and respecting the hygiene of the customer to improve the quality and the customer. It is a useful invention that can improve the reliability.
