Description of the Related Art Generally, in a vending machine that sends out products such as cans and bottles one by one, it is possible to drop products one by one from the upper product slot and stock one product in a row. For example, as shown in Japanese Patent Laid-Open No. 2-247794, there is a type in which a large quantity of one product is stocked in a plurality of rows. In particular, in the latter type, it is necessary to wait in a single row so that each of them can be taken out one by one from the place where they are stocked in a plurality of rows. A specific example is shown in FIG.

That is, the product storage case 1 having an opening / closing door
In the lower part of 01, for example, the products 103 such as cans that are stocked in four rows are provided with a guide surface that guides the products 103 to the first product discharge passage 105 and the second product discharge passage 107 one by one. A product branching member 109 is provided, and a product delivery device 111 called a vent mechanism is provided below the product branching member 109. The product delivery device 111 supports the products in the first and second product discharge passages 105 and 107 in a row in a standby state by a product support stopper 113 that projects in a retractable manner. Shoot down one by one
It has a structure to send to 15.

As described above, the products 103 in a plurality of rows are divided into the first and second products by the product branching member 109.
The product discharge passages 105 and 107 are sorted in a line, and the products in a line are placed in the lower product support stopper 113.
Is placed in a waiting state supported by.

The products 103 in the standby state are delivered one by one to the chute 115 below by the upper and lower product support stoppers 113 alternately appearing and retracting. When the product is sent out, the upper product support stopper 113
The operation of the temporarily supported product falling and being again supported by the lower product support stopper 11 is repeated.

At this time, the lower product support stopper 113
As a result, the load of all the products located above the product directly acts on the product falling, and as a result, a large impact load is applied. For this reason, even if the strength and rigidity of the product support stopper 113 are secured, a large impact load is repeated every time the product is taken out, resulting in a short life and causing trouble and lacking reliability.

Therefore, an object of the present invention is to provide an automatic vending machine which prevents a large impact load from acting on the product support stopper and ensures stable operation for a long period of time.

[0008]

In order to achieve the above-mentioned object, the present invention has a commodity support stopper projecting from a wall surface of a delivery apparatus body in a commodity storage case provided in the vending machine body. A product delivery device, a guide plate for adjusting a road width that forms first and second product delivery passages facing the wall surface of the product delivery device, and an inclined surface provided above the product delivery device and having a mountain-shaped cross section. And a product branching member provided above the product guide member and having a guide surface with a mountain-shaped cross section that can be tilted and rotated by a predetermined angle in correspondence with products of small diameter and large diameter. 1, an invitation having first and second guide portions that are in communication with the second product discharge passage and guide the product at least from the inner wall surface of the product storage case toward the inside and from the inside toward the outside. A product meandering passage is formed to face the plate and meander with the inclined surface of the product guide member, while the inclination angle of the inclined surface of the product guide member is increased or decreased in conjunction with the inclination rotation of the product branch member. It's adjustable.

[0009]

With this vending machine, the products can be delivered one by one by the appearance of the product support stopper.
Upon completion of delivering the product, the product above falls and is again supported by the product support stopper. At this time, since a part of the load of the products above the first and second product discharge passages is borne by the guide portion of the guide plate forming the product meandering passage, the load is greatly reduced, and the product is supported. A large impact load does not act on the stopper.
