In addition, the attitude control device (10) inserts the drive shaft (14) into an arc-shaped elongated hole (16) opened in the top plate (15) of the product delivery passageway (13) and projects the drive shaft (14) upward to make the top plate ( 15) A lock device (17) provided on the upper portion of the lock device holds and holds the product in a sale standby position. That is, the lock device (1
7) is a lock plate (18) that locks the drive shaft (14) in the sale standby position of the attitude control device (10), and urges the lock plate (18) in the direction that locks the drive shaft (14). And a solenoid (20) for releasing the lock plate (18) from the drive shaft (14) to unlock the lock plate (18). As shown in FIG. Detection switch (21) that operates when the lower limit position is reached
Based on the above operation, the solenoid (20) is excited after a predetermined time and the locking of the drive shaft (14) by the lock plate (18) is released. That is, the solenoid (20) is excited by the operation of the detection switch (21) after a predetermined time sufficient to receive the product (A) from the product receiving rack (9) into the product receiving section (11), and the lock plate (18) ) Is used to unlock the drive shaft (14).

Reference numeral (22) is a rotating member that is rotated by the vertical movement of the product receiving rack (9). When the product receiving rack (9) reaches the lower limit position, the slide member (23) is elasticized by the return spring (24). When the product receiving rack (9) moves upward from the lower limit position by sliding backward against the product receiving rack (9) direction,
The return spring (24) is elastically returned to rotate and the slide member (23) is returned to the front by sliding.

(25) rotatably supports a left end, which is one end, on a top plate (15), and a right end, which is the other end, is the slide member (2).
The drive shaft (1) protruding above the top plate (15) is a movable member that is inserted into the engagement hole (23A) of (3) and movably locked.
4) Extends in the left-right direction on the rear side, and comes into contact with the rear side of the drive shaft (14) in a disengageable manner. And
The attitude control device (10) rotated to the product delivery position is brought into contact with the drive shaft (14) of the movable member (25) and pushed forward by the elasticity of the return spring (24) to the standby position. I am able to return. That is, the movable member (25)
And the slide member (23) and the return spring (24)
It constitutes a return device for rotating and returning the attitude control device (10) rotated to the product delivery position to the sale standby position.

Numeral (27) is an urging spring as an urging device having one end locked to the drive shaft (14) and the other end locked to the slide member (23), which is unlocked from the lock plate (18). The attitude control device (10) is urged to rotate to the delivery position.

Therefore, when the product receiving rack (9) of the elevator device (8) that has received the product (A) sent from the product storage device (4) is conveyed downward and reaches the lower limit position, the detection switch (21) is turned on. It operates to stop the downward movement of the product receiving rack (9) by the elevator device (8). When the commodity receiving rack (9) reaches the lower limit position, the rotating member (22) is pressed and rotated to return the slide member (23) to the return spring (2).
It slides backwards against the elasticity of 4). By the sliding movement of the slide member (23) rearward, the movable member (25) is moved rearward at the right end portion around the shaft support portion at the left end portion. At this time, since the drive shaft (14) of the attitude control device (10) is locked by the lock plate (18), the movable member (25) releases the contact with the rear surface of the drive shaft (14) and moves backward. And the biasing spring (27) is strongly pulled by the backward movement of the slide member (23).

On the other hand, when the merchandise receiving rack (9) reaches the lower limit position, the rear side is highly inclined, so that the merchandise (A) in the merchandise receiving rack (9) has the product receiving section (11) of the attitude control device (10). ) To be accepted.

Then, after the operation of the detection switch (21), when a predetermined time sufficient for rolling and receiving the product (A) from the product receiving shelf (9) to the product receiving portion (11) has elapsed, the solenoid (20). Is excited and the lock plate (18) is rotated against the elasticity of the spring (19). The excitation of the solenoid (20) releases the lock of the drive shaft (14) by the lock plate (18).

Therefore, the attitude control device (10) has a bias spring (27).
By the elasticity of the product, the product is urged to rotate in the direction of the arrow (B) shown in FIG. 4 around the shaft support part, and the shielding part (12) is brought into contact with the stopper (28) as shown in FIG. It is rotated to the position. At this time, the product receiving section (11) of the attitude control device (10) is in a state of extending in the longitudinal direction that is long in the depth direction when viewed from the front of the vending machine body, so that the product ( A) is in a state in which the posture is vertically changed with respect to the product outlet (2) and is slid out from the product receiver (11) to the product outlet (2). Further, when the attitude control device (10) rotates, the product (A) of the product receiving unit (11) tries to move in a direction of being shaken off from the product receiving unit (11) by its centrifugal force, but the restriction unit ( 11A).

Then, it is detected by a detection sensor (not shown) that the product (A) is sent from the product receiving section (11) to the product outlet (2), or the elevator device ( When the product receiving rack (9) is returned to the upper standby position by the operation of (8), the rotating member (8) is elastically moved by the return spring (24) along with the upward movement of the product receiving rack (9) from the lower limit position. The slide member (23) slides and returns to the front while the slide member (23) returns to rotate.

The return movement of the slide member (23) causes the right end portion of the movable member (25) to rotate forward. Therefore, the drive shaft (14) abutted and locked by the slide member (23) is pressed forward, and the attitude control device (10) is returned and rotated. When the attitude control device (10) is pivotally returned to the standby position, the drive shaft (14) is retained by the lock plate (18). This state is shown in FIG. Further, in the standby position in this state, the product delivery passageway (13) is blocked by the shielding part (12) of the attitude control device (10), and a mischief from the product take-out port (2) to the product storage device (4) occurs. It can be prevented.

(G) Effect of the Invention Since the present invention is configured as described above, since the product to be delivered to the sales outlet can be delivered vertically, the sales outlet can be made small. In addition, since the attitude control device can bring the product in the rear of the main body closer to the product take-out direction and send it out, the sliding sending part of the product to the product take-out port is reduced, and the product is slid vertically, The product can be reliably delivered without causing a product jam. Furthermore,
When the attitude of the product is changed by the attitude control device, the product is given a centrifugal force by rotation, so that the product can be vigorously delivered to the product outlet. Furthermore, since the product delivery passage is closed by the shielding portion during standby, it is possible to reliably prevent mischief.
