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

[0002]

2. Description of the Related Art Heretofore, as a product unloading device of a vending machine, for example, a device described in Japanese Utility Model Publication No. 8-10833 has been known.

[0003] An example of the above-mentioned conventional product unloading device of a vending machine will be described. FIG. 10 shows the sales standby state.
11 is a side view showing the state during the unloading operation, and FIG. 12 is a side view showing the state where the unloading operation is completed. FIG. 13 is a front sectional view of the product unloading device.

In the figure, 1 is a product storage shelf, 2 is a product support plate, 3 is a front cover of the product storage shelf, 4 is an eccentric cam, 5 is a drive shaft, and 6A, 6B, 6C, 6D and 6E are cigarettes and the like. It is a box-shaped product to be sold. The product storage shelf 1 is a product support plate 2
And the product storage shelf front cover 3 constitute a storage space for the products 6A, 6B, 6C, 6D, and 6E stacked, and the product support plate 2 also has a role of a guide for carrying out the product. A bearing 8 that supports the rotating shaft 7 of the product support plate 2 is provided at the lower rear end of the product storage shelf 1. The product support plate 2 is provided substantially horizontally at the lower end of the product storage shelf 1 with an abutment or a gap therebetween, and supports the stacked products 6A, 6B, 6C, 6D, and 6E. A bearing (not shown) that supports the rotary shaft 7 is provided at the rear end of the product support plate 2, and the product support plate 2 is mounted on the product storage shelf 1 with the rotary shaft 7 as the center via the bearing. It is rotatably mounted. A guide 9 projecting downward is provided at a predetermined position on the lower surface of the product support plate 2.

[0005] The eccentric cam 4 is constituted by an unloading cam 4a and a guide cam 4b formed integrally with or separately from the unloading cam 4a.
It is directly connected to. The carry-out cam 4a is a pair of left and right in a plate shape, and contacts the lowermost product 6A stored in the product support plate 2 by the rotation of the drive shaft 5 and pushes this toward the front edge of the product support plate 2. An outline is formed so as to perform an extruding operation. The guide cam 4b is the unloading cam 4
It is located at a substantially intermediate portion of a and is arranged so as to contact the guide 9. A contour is formed such that the product support plate 2 comes into contact with the product support plate 2 and the guide 9 by the rotation of the drive shaft 5, and the product support plate 2 tilts and returns from a substantially horizontal position to a front downward centering on the rotation shaft 7. I have. The drive shaft 5 is directly connected to a motor 10, and the motor 10 is controlled by a control device that operates based on a sales signal.

The operation of the above-configured merchandise unloading device for a vending machine will be described below.

When the motor is driven by the control device based on the sales signal, the drive shaft 5 rotates, and the carry-out cam 4a and the guide cam 4b rotate in the directions indicated by arrows. The carry-out cam 4a pushes the lowermost product 6A forward from the rear end of the product support plate 2. Synchronously with the ejection of the product 6A by the unloading cam 4a, the contact position between the guide cam 4b, the guide 9, and the product support plate 2 changes according to the contour of the guide cam 4b. Tilting forward. As a result, the distance between the product 6B stacked in contact with the upper portion of the product 6A and the product support plate 2 is increased.
