37 is a detection switch that detects that the basket 8 has reached the negative delivery position, and 38 is a detection switch that detects that the basket 8 is in the lower product receiving position.

Next, the operation of this configuration will be explained.

During sales standby, the basket 8 is at the product receiving position in section F and is in a state where it can receive the product A from the delivery chutes 5 and 6, and the product feeding member 12 is at the bottom 8A separated from the delivery port 17 side. Located at the side end of -1-, the opening/closing member 18 comes into contact with the stopper 20 due to the elasticity of Δ19 and locks, and the movable side is in a high < t, 7 tilted state. It has become.

When a product is delivered from the product storage shelf 4 based on the generation of a sales command, the product A is delivered into the basket 8 through the delivery system 5 or the delivery chute 6. At this time, if the product falls onto the twelfth inclined and curved guide surface 12Δ of the product feed section, this guide surface 12A
J, and is not guided and placed on the bottom 8Aj-, and if it falls onto the guide surface 18A of the opening/closing member 18, it similarly slides on the guide surface 18A and is guided and placed on the bottom 8A.

After receiving the product into the basket 8, the drive motor 9 rotates in the normal direction to rotate the endless chain 29 in the normal direction, and the basket 8 starts to move upward.

Note that the start of the forward rotation of the drive motor 9 means that the product A sent out based on the generation of the sales command is transferred to the delivery chutes 5 and 6.
Either the product is driven by timer control so as to be driven in the forward direction after a predetermined time sufficient for the product to be delivered to the basket 8 through the basket 8, or a detection means for detecting the receiving product is provided in the basket 8, and this detection means It is configured to drive forward when product A is detected.

When the basket 8 starts to move upward by the transport device 11, the gear 15 engaged with the drive band 14 moves to the drive band 14.
Once the endless belt 21 is in the state of rolling on the top and rotates in the normal direction, the endless belt 21 rotates in the normal direction and the product feeding member 12 starts moving in the direction of the opening/closing member 18. Therefore, the product A at the bottom 8Δ7 is pressed toward the opening/closing member 18 by the pressing portion 12B of the product feeding member 12.

When the product feeding member 12 moves on the bottom portion 8A to a predetermined position where it reaches the end on the outlet 17 side, the product A is pushed up and placed on the guide surface of the opening/closing member 18, and The engaging member 16 abuts and locks on the gear 15 on the Basquera l-8 side. Due to this abutment and locking, when the slide member 35 fixing the drive band 14 moves upward together with the basket 8, the gear 15 stops rotating and the movement of the product feeding member 12 is stopped.

Then, when the basket 8 further moves upward by -1 and approaches the upper delivery position, the control member 36 abuts and locks the opening/closing member 18 after placing the product thereon, and as the basket 8 moves upward, the opening/closing member 18 is rotated downward, and when the basket 8 reaches the delivery position, the opening/closing member 18 completely opens the delivery port I7, and the guide surface 18A is tilted toward the product removal port 10. The product A is then delivered to the product take-out port 10. At this time, the guide surface 12A of the product feeding member 12 and the guide surface 18A of the opening/closing member I8 are in a substantially continuous inclined state at the lower position.
M is growing up.

On the other hand, when the Haskent 8 reaches the delivery position, the detection switch 37 is activated and the drive element 9 is stopped. After this stop, product A is transferred from the opening/closing part 18 to the product outlet 10.
After a predetermined time period sufficient for the driver to be sent to
At E9, the reverse drive is started and the -C basket 8 starts to move downward. The operation during this downward movement is the opposite operation to the upward movement, and the explanation will be omitted.When the Haskent 8 reaches the lower product receiving position and returns, the detection switch 38 is activated and the drive element 9 is stopped. It will be in a standby state.

In addition, the product A sent out from the front part of the first product storage shelf 4, which is located directly above the product outlet 10, is placed in the Haskent 8
Instead of being sent to the product retrieval [-11] 0, the item is directly sent out.

If the product sold by the self-J vending machine is single sales (single item sales), change cannot be returned in parallel with the movement of the basket 8, which moves up and down based on the generation of a sales command.

M/(, If the product sales are multi-sales (continuous product sales), Basquera every time a sales command occurs)・8 moves up and down. Therefore, when the basket 8 is moving up and down, that is, when the detection switch 38 detects that the basket 8 is not at the product receiving position, the amount of coins inserted by the customer exceeds the sellable amount. In particular, the generation of a sales command by the product selection operation is stopped 7, and the generation of a sales command is enabled when the detection switch 38 detects the return of the basket 8 to the product receiving position. In addition, during this sales suspension period, the product j! To display to customers that a dispatch operation is in progress to relieve customers' concerns.

(G) Effects of the Invention The present invention allows the product outlet to be formed in a small size on the side of the front of the main body, and can be effectively used as other installation space, such as forming a large exhibition room on the front of the main body. At the same time, the product can be reliably sent from the bus stop to the product take-out port.

In addition, the present invention is a tC device in which the receiving product is pressed to the delivery port side during upward movement in the basket, and the pressing is stopped when the product is placed on the opening/closing member. The product is not crushed or crushed, and the product can be reliably delivered to the product outlet.
