This invention relates to a product delivery device for a vending machine that drops and transports one product from the lowest position.

[Conventional technology]

As this type of product delivery device, one having a configuration as shown in FIG. 6 is known. In the figure, 1
1a is a product storage shelf with the bottom open, 1a is a partition member placed on the left and right sides of the center of the shelf to separate the product column from the following delivery mechanism, and 2 is a bend motor installed at the top of the shelf. , 3 is a vertical rotary drive shaft rotatably driven by the bend motor placed in the center of the shelf, and along this rotary drive shaft, the middle and lowest parts of the shelf are divided into two stages, upper and lower. Product delivery mechanisms 4A and 4B are provided. Here, each set of carrying out mechanisms includes swingable product carrying out flappers 5 and 6 installed corresponding to the left and right product examples, and the flappers facing the lower surfaces of the flappers 5 and 6 in horizontal and hanging positions. A semicircular rotary plate 7 is installed on a rotating shaft to control the swing, and left and right product holders are located one product above the installation position of the product carry-out flappers 5 and 6 and face the product row. It consists of a combination of flappers 8 and 9 and a control cam 10 on a rotating shaft that controls the swinging of the flappers, and the rotating plate 7 and control cam 10 are the same between the upper and lower sets of unloading mechanisms 4A and 4B. installed in phase position. Further, as shown in the figure, the products 11 are sorted into two rows on the left and right within the shelf and placed on the product delivery flappers 5 and 6 in a direct stacking manner. Here, the structures of the product delivery mechanisms 4A and 4B are shown in perspective views as shown in FIGS. 7 and 8. Here, FIG. 7 shows the sales standby state, and FIG. 8 shows the state during sales operation. represents. That is, in the sales standby state shown in FIG. 7, the product carrying flappers 5 and 6 are supported in a horizontal position by the rotary plate 7, and the product holding flappers 8 and 9 are suspended in a free state without being restrained by the control cam 10. In this state, each unloading mechanism of each stage carries a row of products placed on the product unloading flappers 5 and 6 in a direct stacking manner. On the other hand, when the rotary drive shaft 3 rotates 90 degrees from the position shown in FIG. 7, the state shown in FIG. 8 is obtained, and the product carrying flapper 5 on one side is disengaged from the rotary plate 7 and swings into a hanging position. At the same time, the control cam 10 projects the product holding flapper 8 toward the product row, and the sixth
Product 1 on the second tier facing the flapper 8 as shown in the diagram
1 is held between the side wall of the product storage shelf 1. As a result, only one of the lowest products, which has been placed on the product carry-out flapper 5, falls downward. This dropping operation is performed simultaneously by the upper and lower carry-out mechanisms 4A and 4B, and the products that have fallen from the upper carry-out mechanism 4A are replenished onto the row of products carried by the lower carry-out mechanism 4B as shown by arrow A. Unloading mechanism 4B
From then on, the lowest-ranked products fall out of the shelf as shown by arrow B and are carried out. Note that the products taken out from the shelves are delivered to the product outlet of the vending machine via a not-shown computer.

As mentioned above, the product delivery mechanisms 4A and 4B are installed separately at the middle and lower positions in the product storage shelf.
Due to the configuration in which products that are directly stacked inside the shelves are stored separately into upper and lower shelves, products with soft containers, such as relatively thin paper pack products, are crushed and deformed by their own weight. can be effectively prevented.

[Problem to be solved by the invention]

In the conventional direct loading type product unloading device mentioned above,
When changing the product to be sold, the product holding flapper 8,
It is necessary to adjust the installation height so that the control cam 10 facing the flapper 9 and the flapper properly opposes the second-tier product 11 mounted and supported on the product delivery flappers 5 and 6 within the shelf. be. Moreover, in the case where the carrying-out mechanism is installed in two stages, upper and lower, within the shelf as shown in the figure, it is naturally necessary to adjust the carrying-out mechanisms of the upper and lower stages individually as the product size changes.

In this respect, conventionally, the unloading mechanism 4 of each set of upper and lower tiers
Product holding flappers 8 and 9 correspond to A and 4B.
A mechanism for adjusting the installation height of the control cam 10 facing this flapper is provided, and when changing the product 11 to a product of a different size during product sales, the administrator of the vending machine However, in this method, each set of unloading mechanism is individually adjusted, firstly, the adjustment operation is time-consuming and troublesome. . Also, when changing products, there may be operational errors such as forgetting to change the setting of one of the delivery mechanisms, or if there are multiple height position adjustment stages, making a mistake in adjusting each adjustment position between the upper and lower delivery mechanisms. It's easy to happen. Moreover, if sales are carried out with such adjustment operation errors left unaddressed,
Since troubles occur when transporting products, there is a need for improvement measures.

This invention has been made in consideration of the above points, and allows adjustment of the above-mentioned upper and lower sets of dispensing mechanisms to be performed simultaneously in one operation due to a change in the product, thereby solving the problem of the conventional configuration. It is an object of the present invention to provide a product delivery device, particularly a height position adjustment mechanism of the delivery mechanism, which prevents the occurrence of adjustment operation errors and improves serviceability.
