DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a commodity sending device for a vending machine.

[0002]

2. Description of the Related Art Conventionally, products are housed in a row and installed at an outlet of a product passage extending so as to communicate with a product outlet.
For example, as disclosed in Japanese Utility Model Laid-Open Publication No. Sho 56-168879, a product delivery device that delivers the lowest-order product based on a sales order can have its tip protruding and retracting from a base into a product passage. A main stopper and an auxiliary stopper arranged above the main stopper, each of which is independently swingably mounted on the base, an urging spring for urging the main stopper so as to project toward the product passage, and a main stopper. A drive unit for driving a lock control member for alternately locking the auxiliary stopper at a protruding position in the product passage, and a return spring for urging the lock control member in a direction in which the main stopper is locked by the locking rod. 2. Description of the Related Art There is known a product sending device provided with a device.

[0003]

The main stopper of this type of apparatus is urged by an urging spring so as to protrude toward the product passage. However, dust or the like adheres to a portion supported by the shaft. If it is difficult to rotate the product, the product may rotate by its own weight when opened, but may not rotate when returning. Although it is conceivable to increase the urging force of the urging spring, the product cannot be discharged smoothly due to its own weight. When the auxiliary flap releases the support of the product in a state where the main stopper does not rotate at the time of return, the product not sold is discharged.

In view of the above, the present invention provides a product delivery device for a vending machine which has a simple structure and can discharge a product with a small force.

[0005]

SUMMARY OF THE INVENTION According to the present invention, goods are stored in a row and are installed at an outlet of a goods passage extending so as to communicate with a goods take-out port, and the lowest order goods are sent out based on a sales command. In the product delivery device, the product locking portion at one end for locking the lowest order product, the control locking portion at the other end, and the pressing portion are integrally provided, and the product locking device at one end is rotatably supported. A main stopper having a stop part capable of protruding and retracting into the product passage, a product locking portion at one end for locking the next sales product positioned above the main stopper, and a control member at the other end are integrally provided. An auxiliary stopper rotatably supported by a support shaft and having one end of the product locking portion protruding and retracting in the product passage; and a state in which the product locking portion of the auxiliary stopper protrudes into the product passage. Press the pressing portion of the main stopper during the return rotation of The main stopper is provided at a position where the product locking portion of the main stopper projects into the product passage and is locked to the control locking portion, and is rotatably inserted into the control member and provided with a flange at one end. A stop rod, a shaft on the control member, which is attached at a distance greater than a distance from the support shaft to the lock rod, and a shaft of the lock rod opposed to a flange portion of the lock rod. A mounting wall for preventing the detachment, a driving device connected to the control member via the shaft and rotating the control member in a direction to release the locking rod from the control locking portion;
An elastic member attached to the shaft to bias the control member.

[0006]

The locking rod of the control member is locked to the control locking portion of the main stopper, the product locking portion of the main stopper projects into the product path, and locks the lowest product in the product path. ing. When the driving device rotates the control member against the elasticity of the elastic member based on the sales command, the control member applies a force in a direction to release the locking rod from the control locking portion. Since the rod is rotatably attached to the control member, the locking rod rolls at least at the initial movement, so that the frictional force with the control locking part is small, and the locking rod is easily locked with the control locking part. Can be canceled. When the locking rod is moved by the rotation of the control member, the auxiliary stopper projects into the product passage with the rotation of the control member. When the main stopper is released from the locking by the locking rod, the lowest product is sent out and the next product is locked by the auxiliary stopper. After the product is delivered, the driving device stops driving, and the control member is returned by the elastic member. At the time of this return operation, the locking rod presses and urges the pressing portion of the main stopper, rotates the main stopper to return and locks the control locking portion, and the auxiliary stopper retracts and returns from the product passage. Further, the locking rod is rotatably inserted into the control member and has a flange at one end, and the locking rod is prevented from coming off by a mounting wall opposed to the flange of the locking rod. The stop rod can be easily rollably mounted.
