Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to commodity dispensing devices, and particularly to a flapper dispensing type commodity dispensing device.

Conventional technology Conventionally, this type of product dispensing device is shown in Figs. 5 to 9-1-.
Cr% is configured as shown in the figure. Figure 5 is a longitudinal sectional view of the product dispensing device, where (1) and (2) are the shafts (3) and (4), respectively.
Both cradle (1) (2)
The downward rotation is restricted by a single cam plate (5). The cam plate (5) has a semicircular shape and is fixed to the tip of the camshaft (6) so that it can rotate horizontally.

(7) are the products in the first column stacked on the first pedestal (1);
, I3... (8) is the second cradle (2
) in the second column, which is also stacked in II
1. Labeled as H2-H3... (9) (10
) are the first and second stoppers, and the camshaft (6
) is pushed out by the cam body (11) fixed to the first
, place the second product from the bottom of the second column on the stocker wall (
12) It supports the second or more stacked products by pressing it against the side.

The rotation of the camshaft (6) is driven by a motor (not shown), a stop cam (not shown) attached to the camshaft (6), and a cam switch (not shown) that detects the state of the stop cam. ] as follows:
-2- Controlled. Note that conventionally, the motor rotates only in a single direction. Moreover, the products (7) and (8) in the first and second columns are the same product, and each time a payout instruction is detected, the product is paid out from the first or second column.

Figure 7 shows the first and second cradle (1), (2) and cam plate (5) in the process of dispensing ■□ at the first dispensing instruction detection and ■□ at the second dispensing instruction detection. Indicates the status of

FIG. 7(a) shows the initial state of FIGS. 5 and 6. FIG. When the first dispensing instruction is detected, the cam plate (5) rotates 90 degrees clockwise as shown in Fig. 7(b), and the first cradle (1) and the cam plate (5) are connected to each other. The engagement will come off. In addition, the cam plate (1) rotates 90 degrees in this way, and the first pedestal (1)
) rotates downward, the second product ■2
As shown in Fig. 7, the cam body (11) is connected to the stocker wall (
12), and when the first pedestal (1) rotates downward, only the product 11 is dispensed. When the dispensing of the product (■) is completed, the cam plate (5) further rotates 90 degrees as shown in Figures 7(b) to 7(c), and the first cradle (5), which had been rotated downward, is 1) and release the pressing of the product I2 by the cam body (11). When the second dispensing instruction is detected, the cam plate (5) rotates 90 degrees as shown in FIG. 7(c) to FIG. ) is disengaged and product (1) is dispensed as shown in FIG. 9. When dispensing is completed, the product returns to the initial state shown in FIG. 7(a).

In this way, conventionally the cam plate (5) rotates in a single direction,
One product is dispensed every time the machine rotates 180°.

Problems to be Solved by the Invention In such a conventional configuration, the products in the first column and the products in the second column are
It is not possible to distinguish between the products in the column and the products in one column and pay out only the products in one column consecutively.

Although the present invention uses a flapper dispensing method, the first and second
To provide a product dispensing device capable of continuously dispensing only one of the products in a column.

Means for Solving the Problems The product dispensing device for a vending machine of the present invention controls the rotation of the first and second pedestals, each of which is pivoted at one end so as to be able to rotate downward. A semicircular first cradle is pivoted to horizontally rotate at a lower position of the second cradle. The second pedestal is supported and regulated by a common cam plate, and the cam plate is rotated by a predetermined angle to release the contact between the cam plate and one of the first and second pedestals, and the cam plate is placed on the pedestal. The present invention is characterized in that the product is configured to dispense the products stored in the first or second column, and the direction of rotation of the cam plate is switched depending on the selected column.

Effect: With this configuration, the direction of rotation of the cam plate is switched not in a single direction but in accordance with one selected column. The products in the second column on the side of the second pedestal can be dispensed alternately, or the products in one column can be dispensed continuously.

Embodiments Hereinafter, embodiments of the present invention will be explained based on FIGS. 1 to 3. Note that since the mechanical parts are the same as those of the conventional one, the motor that drives the camshaft (6) and its surrounding parts will be explained here.
