Description

[Detailed Description of the Invention] The present invention relates to a vending machine that allows products to be taken out manually by inserting a predetermined amount of money into the vending machine.

Conventionally, this type of vending machine has been configured to open a door that opens and closes regardless of whether money is inserted, and to manually take out products that can be taken out when a predetermined amount of money is inserted. Therefore, even those who do not intend to purchase products can freely open the door, and there are concerns that various mischief may occur. Furthermore, when the product is configured to cool or heat the product, there is a drawback that the cooling or warming effect is impaired due to unnecessary opening of the door.

On the other hand, Japanese Utility Model Publication No. 54-94292 discloses a vending machine in which a plurality of product storage chambers are formed by a partitioning device and a lockable outlet door is provided in the front of each product storage chamber. . The locking device for such a door is
The solenoid selected by the selection button is activated momentarily to unlock the door, allowing the door to open. If the door is biased in such a way that the door cannot be opened, there is a drawback that the product may not be sold properly. In other words, if the door is biased in the opening direction when the solenoid operates,
Since the link shaft of the link member is in strong contact with one side of the actuating plate, the link member cannot be moved downward by the instantaneous action of the solenoid, resulting in a drawback that the door cannot be opened.

In view of the above, the present invention provides a device that prevents the door from being opened unnecessarily and also prevents the door from opening incorrectly due to mischief.

Embodiments of the present invention will be described below based on the drawings.
Reference numeral 1 denotes a vending machine main body, and a main door 2 is provided on the front side and is pivoted to be openable and closable. Reference numeral 3 denotes a signboard part provided at the upper part of the main door 2; 4 a door provided in the main body 1 so as to be able to open and close a sales outlet 5 having a product locking sales mechanism part (not shown); is rotatably supported. The pivot support is provided with a spring 6 which always urges the door 4 to close the sales outlet 5. Further, a handle 8 is provided on the opening/closing end 7 of the door 4, and a lock portion 9 is provided on the side surface of the door 4 corresponding to the handle 8, and a preventive lock is provided on the front surface of the lock portion 9 corresponding to the lock portion 9. A member 10 is provided. Reference numeral 11 denotes a locking member whose one end is rotatably supported on the main door 2, and the other end has a locking portion 12 bent rearward so as to be connected to and disengaged from the lock portion 9 of the door 4. The stop portion 12 is configured to pass through an opening 13 provided in the main door 2 and correspond to the lock portion 9. Reference numeral 14 denotes a spring as a return member provided at the support portion of the locking member 11;
2 protrudes from the opening 13 and is urged to engage with the lock portion 9. Reference numeral 15 denotes a movable member rotatably supported at one end on the main door 2, and a locking member 11 at the other end.
It has a locking piece 17 that is bent to engage with an engaging member 16 that is bent and provided, and the locking piece 17 engages with the engaging portion 16 when the movable member 15 rotates. It is made to do so. A spring 18 serves as a return member provided on the support portion of the movable member 15, and urges the movable member 15 to come into contact with a stopper 19 provided on the main door 2. Reference numeral 20 denotes an electromagnetic solenoid that is energized when a predetermined amount of money is inserted, and is de-energized when the product is removed from the sales outlet 5.
1 is connected to the movable member 15 by a spring 22, and the locking piece 17 of the movable member 15 is connected to the engaging portion 1 of the locking member 11.
6. Reference numeral 23 denotes a guide member which also serves as a stopper for the operating punch 21 of the electromagnetic solenoid 20, and the spring 22 is configured so as not to normally generate an elastic force between the movable member 15 and the operating punch 21. Further, the spring 22 has greater elasticity than the combined elastic force of the springs 14 and 18.

Next, the operation of the above configuration will be explained. FIG. 2 is a diagram of the customer waiting state. That is, the locking member 11 has a locking portion 12 projected from the opening 13 by the elasticity of the spring 14, and the locking portion 12 locks the lock portion 9 of the door 4. Therefore, even if the door 4 is tried to be opened using the handle 8, it cannot be opened.

Next, when a predetermined coin is thrown, the electromagnetic solenoid 2
0 is energized and the operating punch 21 is suctioned to the right in FIG. Therefore, first, the elasticity of the spring 22 urges the movable member 15 counterclockwise around the support portion. Therefore, the movable member 15 rotates against the elasticity of the spring 18. At this time, the locking piece 17 of the movable member 15 locks on the engagement portion 16 of the locking member 11, and the locking member 11 rotates counterclockwise about the support portion against the elasticity of the spring 14. . Therefore, the locking portion 12 of the locking member 11 separates from the locking portion 9 of the door 4 and locks the main door 2.
It is stored inward. This state is shown in FIG. Further, when the electromagnetic solenoid 20 is energized and the customer is urging the door 4 forward, that is, to open the sales port 5, the operating punch 21 acts as a suction force against the elasticity of the spring 22. However, the locking part 1 is attached to the locking part 9.
2 is in a strongly locked state, the locking member 11 maintains the locked state with the lock portion 9, and the movable member 1
5, the locking piece 17 is locked to the engaging portion 16 of the locking member 11 and rotation is prevented. and door 4 by customer
When the opening biasing operation of the locking member 11 and the enabling member 15 are respectively rotated counterclockwise by the elasticity of the spring 22, the locking portion 12 of the locking member 11 is released from the locking portion 9. It is stored inside the main door 2.

Next, the customer rotates the door 4 forward against the spring 6, that is, clockwise around the pivot in FIG. The power is cut off. Accordingly, the locking member 11 rotates clockwise about the support portion due to the elasticity of the spring 14, and the locking portion 12 projects from the opening 13 and returns to its original position. Further, the movable member 15 rotates clockwise around the support portion due to the elasticity of the return rotation spring 18 of the locking member 11 and returns to contact with the stopper 19 . Along with this return operation, the spring 22 is returned to the left, and the operating punch 21 returns by sliding on the guide member 23. Then, when the customer lets go of door 4, door 4
is rotated counterclockwise around the shaft support in FIG. 5 due to the elasticity of the spring 6, and when the lock portion 9 reaches the locking portion 12 protruding from the opening 13, it is engaged by the lock portion 9. Stop portion 12 is pressed. This state is shown in FIG. Therefore, the locking member 11 is rotated counterclockwise about the support portion against the elasticity of the spring 14. At this time, the locking piece 17 of the movable member 15 and the engaging portion 16 of the locking member 11 are in the direction of separation, so the movable member 15 does not operate. When the door 4 further rotates, the locking portion 12 locks onto the lock portion 9 due to the elasticity of the spring 14, thereby closing the door 4.

As mentioned above, the present invention has a door that is always biased in the closing direction by a spring, a lock part provided at the opening/closing end of the door, and a locking part that removably corresponds to the lock part. a movably supported locking member; a spring that urges a locking portion of the locking member to engage with the lock portion; and a rotatably supported locking member that engages the locking member when rotated. a movable member having a locking piece that disengages the locking portion from the lock portion; a spring that causes the movable member to return to rotation; and a movable member that engages the locking member upon insertion of a predetermined coin. The door is equipped with an electromagnetic solenoid that operates in the direction of the door and returns when the product is removed. Since the door is closed by pressing the stop part, only the customer who intends to purchase the product can open the door, and unnecessary opening can be prevented. Also, even if the door is biased in the opening direction by a mischievous or impatient customer, the solenoid can operate normally, so the door will not open as soon as the door bias is weakened. This has the effect of preventing poor sales of products due to mischief or the like.
