And the operation of the select button is detected by the control unit 500, and the number of goods initially loaded on the spiral 350 by the control unit 500 and the rotation of the motor 360. Number of the control unit 500 The control unit 500 transmits a control signal when the comparison / analysis by the control unit 500 and the number of rotations of the motor 360 analyzed by the control unit 500 are less than or equal to the number of goods loaded in the spiral 350. In addition to transmitting to the driving unit 610, the motor 360 and the spiral 350 is driven by the motor driving unit 610, and is loaded on the spiral 350 by the driving of the spiral 350 The product is composed of the step of discharging the product from the product dispensing device 300 to the product discharge port 214 and the step of the user to purchase the purchased product discharged to the product discharge port 214.

On the other hand, as shown in Figure 5 and Figure 6 of the present invention, the method of detecting the product, the number of revolutions of the motor 360 analyzed by the control unit 500 and the number of goods initially loaded in the spiral 350 and If the control unit 500 transmits a control signal to the motor driver 610 and the driving of the motor 360 and the spiral 350 is terminated by the motor driver 610 to stop the sale of goods. And, the sold out state is displayed on the display unit 620 by the control signal of the control unit 500.

Hereinafter, the merchandise sold out detection method of the present invention will be described in detail with reference to FIGS.

First, the manager of the vending machine loads the merchandise in the spiral 350 of the merchandise dispensing apparatus 300 and inputs the rotational speed of the motor 360 according to the number of the merchandise loaded into the controller 500.

For example, assuming that one product is discharged to the product outlet 214 by the rotation of the spiral 350 when the motor 360 rotates, when 10 products are loaded in the spiral 350, The number of revolutions of the motor 360 of 10 is input to the controller 500.

Thereafter, the user of the vending machine inserts the amount corresponding to the purchased product into the coin inlet 211 and the bank inlet 212 (step 711), and operates a selection button (not shown) of the selection unit 213. In operation 712, the operation of the selection button is detected by the controller 500, and the number of goods loaded into the spiral 350 by the controller 500 and the number of rotations of the motor 360 are increased. It is compared / analyzed by the control unit 500 (step 713).

In this case, when the number of rotations of the motor 360 analyzed by the controller 500 is less than or equal to the number of goods loaded in the spiral 350, the controller 500 transmits a control signal to the motor driver 610. In addition, the motor 360 and the spiral 350 are driven by the motor driving unit 610 (steps 714 and 715), so that the user's purchase product is transferred from the product discharge device 300 to the product discharge port 214. Ejection is made (step 716).

In addition, the user can purchase the purchased product discharged to the product discharge port 214 and can easily use the desired product at the desired portion.

On the other hand, if the number of revolutions of the motor 360 analyzed by the controller 500 is equal to the number of goods initially loaded on the spiral 350, the controller 500 transmits a control signal to the motor driving unit 610. In addition to the transmission, driving of the motor 360 and the spiral 350 is terminated by the motor driving unit 610. (Step 718, Step 719).

When the driving of the motor 360 and the spiral 350 is completed, the sale of the product that the user wants to purchase is automatically stopped (step 721).

In addition, when the sale of the product is stopped, the control unit 500 transmits a control signal to the display unit 620, and the display unit 620 receives this to display the sold out state of the door 200. (Step 722)

Therefore, the user of the vending machine can purchase a desired product by operating the selection button of another product instead of the selection button of the sold out product.

As described above, according to the present invention, the method for detecting the sold out of the product comprises controlling the rotation speed of the motor corresponding to the number of the goods loaded in the spiral of the product discharge site to detect the sold out state of the sold product. Since the motor is prevented from being driven by the control signal of the controller when sold out, the user does not lose the amount corresponding to the sale product.
