The operation of the vending machine 100 according to this embodiment will be described below. One product row is composed of the same product 200. On a plurality of product shelves 2, constituent products 2
00 different product rows are placed. The user selects a desired product 200 and presses a product selection switch (not shown). The control device (not shown) provided in the vending machine 100 operates, the servo motor 46 of the elevator driving device 4 rotates, and the screw rod 43 rotates through the reduction gear provided in the gear box 45, and the screw rod 43 Is guided by the guide rod 42 and moves downward from the uppermost position, which is the origin position, so that the elevator 1 fixed to the slider 41 moves the desired product 200 from the uppermost position, which is the origin position. The product approaching the shelf 2 on which the row is placed.
The servomotor 46 is stopped, and the elevator 1 is stopped facing the lower edge of the product shelf on which the row of the desired product 200 is placed. The stop position control of the elevator 1 is accurately performed by comparing the number of pulses by the encoder attached to the servomotor 46 with the number of pulses indicating a preset product shelf position.

The servo motor 9 of the commodity dispensing mechanism driving device 9 facing the commodity row constituted by the desired commodity 200
1 rotates, and the reduction gear 93 rotates. The drive rod 94 meshing with the reduction gear 93 is moved left or right from the origin position where the left and right ends are at the same height position to the product shelf 2 on which the product row constituted by the desired product 200 is placed. , And the left or right end of the drive rod 94

The pressing piece 35 is pushed up obliquely upward against the elastic force of No. 4.
Since the arc-shaped drive rod 94 makes an arc movement, the drive rod 94
The protruding end portion moves substantially along the inclined gap between the vertically adjacent product shelves 2. As a result, the gap between the vertically adjacent product shelves 2 is narrow, and the lower surface of the product shelf 2 on which a desired product row is placed and the top of the product 200 placed on the product shelf 2 immediately below the product shelf 2 Is small, the protruding end of the drive rod 94 can move in the narrow inclined gap without interfering with the commodity 200 below. As a result of the end of the driving rod 94 pushing the push piece 35 obliquely upward, the intermediate arm 33 of the product payout mechanism 3 is moved obliquely downward to the first
From the position, the joint moves to the second position diagonally above, the joint of the second stopper 32 retreats below the product shelf 2, and the first stopper 31 projects above the product shelf 2. The lowermost commodity 200 of the desired commodity row loses the support of the second stopper 32 and falls from the lower end of the commodity shelf 2 into the elevator 1. The second product 200 from the lowermost end of the desired product row is supported by the first stopper 31. As a result, all other products 200 belonging to the desired product row are prevented from falling from the product shelf 2.

When the lowermost commodity 200 of the desired commodity row falls from the lower end of the commodity shelf 2 into the elevator 1, the side plate 7 of the elevator 1 is pushed down to the commodity conveying conveyor 6 side. The switch 8 is pressed by the pushed down side plate 7, and the side plate 7
Is detected, that is, that the desired product 200 has been paid out from the product shelf 2 to the elevator 1. After the fallen side plate 7 has moved into the elevator 1,
It is raised by the urging force of a spring (not shown). The upright side plate 7 facing the pushed down side plate 7 prevents occurrence of a situation in which the commodity 200 gets over the elevator 1 and falls to the opposite side. After it is detected that the desired product 200 has been delivered from the product shelf 2 to the elevator 1, the servo motor 91 rotates in the reverse direction, and the drive rod 94 returns to the home position. The return of the driving rod 94 to the origin position is detected by the optical sensor 95 for detecting the origin position. Desired goods 20
If it is not detected that “0” has been dispensed from the product shelf 2 to the elevator 1, the drive rod 94 is driven again to try to dispense a desired product 200 from the product shelf 2.

After the desired product 200 is dispensed from the product shelf 2 to the elevator 1, the elevator 1 moves up and down to the height position of the opening 51a of the framework 5, and eventually to the height position of the product outlet 102a. To reach. Since the elevator 1 is assembled in the framework 5, it has sufficient strength and operates stably. During the movement of the elevator 1, the upright side plate 7 prevents the commodity 200 from falling from the elevator 1. The goods transport conveyor 6 starts, and the goods 200
Is transported by the product transport conveyor 6 toward the opening 51a. As shown in FIG.
Through the opening 51a and the opening 101a of the middle door 101, falls onto a product take-out shelf 103 disposed below and in front of the opening 101a, and is taken out of the vending machine 100 via the outer door 102 and a product take-out opening 102a. .

The maintenance staff opens the outer door 100 and the inner door 101, and pulls the product shelf 2 forward. The moving rails 21 and 22 fixed to the lower surface of the product shelf 2 slide on the fixed rail 23 fixed to the framework 5 and the fixed rail 24 fixed to the structural member 104 of the vending machine 100, and the product shelf 2 moves forward. Drawn to. The maintenance staff places the product 200 on the product shelf 2 pulled out, and then pushes the product shelf 2 back to the normal position. Even when the gap between the product shelves 2 is narrow, the products can be stored in the product shelves 2 without any trouble. Two moving rails 21 and 22 fixed to the lower surface of the product shelf 2 and extending in the front-rear direction are fixed from below by two fixing rails 23 and 24 fixed to the structural member of the vending machine and extending in the front-rear direction. Since the fixed shelves 23 are supported and the fixed rails 23 are sandwiched by the moving rails 21 in the left-right direction, the commodity shelves 2 can be pulled forward while preventing the goods shelves 2 from sliding down diagonally right or left.
The protrusion 21a formed on the first moving rail 21 contacts the first fixed rail 23, and the protrusion 22a formed on the second moving rail 22 contacts the second fixed rail 24, so that the protrusion 21a is fixed to the moving rails 21 and 22. Friction resistance between the rails 23 and 24 is reduced. Since the fixed rail 23 is sandwiched in the left and right direction by the moving rail 21 and the movement of the product shelf 2 in the left and right direction is restricted, the drive rod 94 of the product delivery mechanism driving device 9 projects to the side of the elevator 1 and the product delivery mechanism 3 When the pressing piece 35 is pressed, the product shelf 2 is not moved and only the product payout mechanism 3 is driven, and the product 200 is paid out without any trouble. Therefore, there is no possibility that the dispensing of the merchandise 200 may be hindered by making the merchandise shelf 2 drawable. Since the fixed rail 23 is sandwiched between the moving rails 21 in the up-down direction, there is no possibility that the product shelves 2 will tilt forward and downward when the product shelves 2 are pulled out forward. Therefore, there is no hindrance to the product storage operation.
