The reason for providing a pair of upper and lower 14 is that if only the lower one is used, the weight of all the products (S) will be added to the lower product dispensing device (A), making it difficult to smoothly dispense the products, and a large driving force will be required. It's because you need it.

The procedure for dispensing the product 18 will be explained based on the above configuration. First, in the non-dispensing state shown in FIGS. 3 and 4, when a coin is inserted into the slot and a predetermined product selection button is pressed, the selected drive motor 32 is activated by the command signal.
is actuated, and the drive shaft 11 is rotated in the direction of arrow A. Then, the product holding cam 26 at position (a) in FIG.
The product holding plate 24 on the left side of Fig. 3 is also rotated in the same direction.
When the cam 26 reaches the (opening) position, it is projected outward using the bent portion of the lower end of the product holding plate 24 or the support pin 23 as a fulcrum, and is pressed against the side surface of the second product 18 from the bottom. Therefore, the second product 18 from the bottom is held between the lower bent portion of the product holding plate 24 and the inner wall 8. The product support plate 15 also rotates integrally with the drive shaft 11,

Further, the product 18 dispensed from the upper product dispensing device 13 is dropped onto the stacked products 18 supported by the lower product dispensing device l4.

As the drive shaft j1 continues to rotate beyond 90°, the product receiving plate 17 on the left side in FIG. 26 begins to separate from the product holding plate 24 on the left side of FIG. 6, the bent lower end of the product holding plate 24 on the left side of FIG. It falls onto the product 18 or the product receiving plate 17. Next, when the drive shaft 11 rotates 180 degrees, that is, when the cam 26 reaches the position (c) as shown in FIG. 7(b), the drive motor 32 stops operating and the product dispensing device 13. 14 is in a non-payout state. Next, put the coin into the slot again and press the product selection button.As in the previous case, the drive motor 32 moves the drive shaft 11 to the arrow A.
The product 18 on the right side of FIG. 7 is dispensed.

In the above embodiment, the case where a relatively small product 18 is handled has been explained as an example, but when handling a medium-sized product 18, first remove the operation hole closing plate 30 by removing the screws, and then Remove the pin 23 and the connecting pin 28 to remove the first window blocking plate 29 and product holding plate 24, and then insert another window blocking plate (not shown) that is lower in height than the window blocking plate 29 inside the window 22. into the upper end hole and both vertical plates 20
Insert the connecting pin 28 into the hole 21 at the upper end, close the upper part of the window 22 with another window closing plate, and then connect the upper end hole of the product holding plate 24, the lower end hole of another window closing plate, and both vertical plates. By inserting the support pin 23 into the second hole 21 from the top of the product 20 and connecting the product holding plate 24, the bent portion of the lower end faces the center of the side surface of the second medium-sized product 18 from the bottom. good. When handling even larger products 18, support pins 23 are installed in the upper end holes of the product holding plate 24 and the top holes 2l of both vertical plates 20.
2\ to further raise the height of the product holding plate 24.

Effects of the Invention As described above, according to the product dispensing device of the present invention, since the product is held by the product clamping body at a plurality of locations on the product storage path, the entire product is placed on the product support located at the lower end of the product storage path. The weight of the product is not added, the product can be smoothly dispensed, and the driving force is small.
