Next, the operation of the lifting device of the vending machine according to the present invention configured as described above will be described in detail with reference to the operation flowchart of FIG.

That is, in step S1, the controller 10 determines whether the menu selection button of the menu selection unit 12 is pressed, and if it is determined that the menu selection button has been operated, the control proceeds to the subsequent step S2 to select the menu. It is determined whether the quantity selection button of the unit 12 is operated. As a result of the determination in step S2, if the quantity selection button is operated, the control unit 10 controls the discharge mechanism 18, and then proceeds to S3.

Thereafter, in step S4, when the quantity detection signal of the product is applied from the discharge sensing unit 14 composed of the product quantity detecting unit 36, the light emitting element 14A, the light receiving element 14B, and the light shielding member 20D (i.e., When the product is discharged, the light blocking member 20D is also lowered as the top plate 20A of the housing 20 is lowered by the weight of the product, and when one product is discharged, light incident on the first light receiving element is emitted from above. When the K products are discharged, the light incident to the K-th light receiving element is blocked. Accordingly, since the low-level signal is input from the light-receiving element to the control unit 14, the control unit 14 can easily identify the number of discharges.], And the quantity detection signal is a quantity set value by operating the quantity selection button. It is judged whether it is a low level signal from the K-th light receiving element corresponding to (K), and if so, control proceeds to the next step S4.

In step S4, the control unit 10 controls the rotation driving unit 22 so that the motor 40 is driven so that the rotation of the motor 40 is carried out through the pulley 42, the belt 46, and the pulley 48. It is transmitted to the 38 so that the receiving portion 20 on which the product 52 is mounted is raised and the timer 16 is operated. Subsequently, in step S5, the control unit 10 determines that the time value t of the timer 16 is a predetermined first set value [t1; That is, it is determined that the storage unit 20 is moved by the driving force of the motor 40 to reach the product extraction unit 32 accurately and reaches the drive time of the motor 40]. In this case, the control proceeds to the next step S6 to control the rotary drive unit 22 so that the motor 40 is stopped so that the accommodating part 20 on which the product 34 is mounted rises to the product takeout part 32 accurately. In addition, the timer 16 is reset, the control is terminated, and the controller waits for input from the menu selection unit.

On the other hand, if the quantity selection button has not been operated as a result of the determination in step S2, then control proceeds to step S7 where the control unit 10 controls the discharge mechanism 18 to discharge one product, and this discharge When the discharge detection signal of the product is input to the control unit 10, the control is detected by the output detecting unit 14 and input to the control unit 10 (the low level signal from the first light receiving element is applied). The flow proceeds to step S4.

According to the present invention described above, the product taking out part of the vending machine is installed high, the product quantity detecting part made up of an optical sensor is installed on the side of the accommodating part, and a rotation mechanism for moving the accommodating part containing the product to the product taking out part. As a result, the discharge of the product is sensed by the optical sensor, and the product is raised to the lead-out part by the rotation mechanism.
