The vending machine is in a standby state, and is indicated by a solid line in FIG. 3, and as shown in FIG. 4, the joint of the second stopper 2 b of the product stopper A projects above the product shelf 1, and is located at the lower end of the product row. Product 2
00 is supported to prevent all products 200 belonging to the product row from falling. The solenoid 12 of the product receiving member is stopped, and the pin 14 is in the retracted position shown by a solid line in FIGS.

The user selects a desired product 200,
Press a product selection switch (not shown). A control device (not shown) incorporated in the vending machine operates, and the product receiving member 11 moves up and down to approach the product shelf 1 on which the specified product 200 is placed. When the product receiving member 11 moves from below to the target product shelf 1, the product receiving member 11
Once passes through the target shelf 1 at a high speed, then decelerates and descends, approaching the target shelf 1. Product receiving member 11
Moves from above to the target shelf 1 at a high speed, descends to the vicinity of the target shelf 1, and then descends at a reduced speed to approach the target shelf 1. Since the pin 14 is at the retracted position, there is no possibility that the pin 14 and the rotating plate 10 interfere with each other while the product receiving member 11 is moving at high speed.

In synchronization with the start of deceleration of the product receiving member 11, the solenoid 12 on the side facing the target product shelf 1 is synchronized.

As the rotating plate 10 rotates, the cam 6 rotates clockwise as viewed from the front against the urging force of the spring 9. With the rotation of the cam 6, the rotor 7 of the lever 8 urged to rotate by the spring 9 moves the cam 6.
And moves on the periphery of the cam 6 while being in contact with the periphery of the cam. When the rotor 7 passes through the center of the petals of the cam 6, the spring 9
The biasing force drives the cam 6 to rotate in the same direction as the biasing force of the pin 14. When the rotor 7 reaches the concave portion between the adjacent petals of the cam 6, the rotation of the cam 6 is stopped by the urging force of the spring 9. Accordingly, the cam 6 always moves the rotor 7 of the lever 8 from the position where the rotor 7 of the lever 8 abuts the recess between the adjacent petals of the cam 6 to the next adjacent petal of the cam 6. Rotate to a position where it comes into contact with the concave portion between. As a result, the cam 6 surely rotates 120 degrees.

The second intermediate portion 2b of the second stopper front row of goods stopper A ₅ are, therefore falls to the second cut-out portion 4a ₂ of the fan-shaped cross section of the cam 4a, the first cut-out portion 4a cam follower portion 2b ₂ are without any trouble ₁ Can move along. As shown in FIG. 7 (b), with the rotation of the cam 4a, the cam follower portion 2b ₂ is and through the first half of the first cut-out portion 4a ₁ moves to the central portion under the urging force of the spring 3 Then, the lower half of the second stopper 2b of the product stopper A in the front row swings counterclockwise when viewed from the front, and as shown by the dashed line in FIG. And the joint of the first stopper 2a protrudes above the product shelf 1. The lowermost product 20 in the product row supported by the product stopper A in the front row
No. 0 loses the support of the second stopper 2b, falls from the lower edge of the product shelf 1, is reduced in speed, and is stored in the descending product receiving member 16. Product 200 adjacent to the lowest product 200
Are supported by the first stopper 2a to prevent the remaining product 200 from falling.

When the cam 4a further rotates, as shown in FIG. 7 (c), the first notch 4a having a sectoral cross section of the cam 4a.
The latter half of ₁ comes into contact with the bent portion 2b ₄ ′ of the first intermediate portion of the second stopper 2b, and pushes up the bent portion 2b ₄ ′. As a result, the cam follower portion 2b ₂ of the second stopper
Begins to move toward the end from the first notch portion the central portion of 4a ₁ sector cross-section of the cam 4a, the second stopper 2b which was of lower F retraction shelf 1, rising upward toward shelves 1 start. Since the bent portion 2b ₄ ′ in the out-of-plane direction is present, the cam 4 is smaller than when all the lower half portions of the second stopper 2b extend in the same plane.
delayed timing cam follower portion 2b ₂ of the second stopper has reached the center of the first cut-out portion 4a ₁ of the fan-shaped cross-section of a starts to move toward the first cut-out portion 4a ₁ of the end, the second The beginning of the rising of the stopper 2b is delayed, and the commodity 200 at the bottom end of the commodity row is moved to the second stopper 2b.
The time to lose support of b is long. As a result, the commodity 200 at the lowermost end of the commodity row surely falls from the lower edge of the commodity shelf 1.

The cam follower portion 2b ₂ of the second stopper
When There is moved to the first notch end of 4a ₁ sector cross-section of the cam 4a, as shown in FIG. 7 (d), the lower half portion of the second stopper 2b of the front row of goods stopper A, the spring 3
Against the urging force of, rotates clockwise when viewed from the front,
As shown by the solid line in FIG. 3, the joint of the first stopper 2a is retracted below the shelf, and the joint of the second stopper 2b projects above the shelf. As a result, the product 200 newly positioned at the lowermost end of the product row is supported by the second stopper 2b, and all the products 2 belonging to the product row are
00 is prevented from falling.

The cam follower portion of the second stopper 2b of the commodity stopper A in the center row extends along the cylindrical side surface of the cam 4b from the center in the circumferential direction of the cylindrical side surface to the first portion having a fan-shaped cross section.
Move to the beginning of the notch, and move to the rear row of product stoppers A
The cam follower portion of the second stopper 2b is a cam 4c
Since it moves from the end of the first notch of the sectoral cross section to the center in the circumferential direction of the cylindrical side surface along the cylindrical side surface of
The lower half of the second stopper 2b of the product stopper A in the center row and the second stopper 2b of the product stopper A in the rear row
