DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a product discharging device for a vending machine that stacks and stores products vertically in a product storage device and sequentially drops and transports the products one by one starting from the lowest position. It is something.

2. Description of the Related Art In recent years, product dispensing devices for vending machines have been required to sell a wide variety of products and irregularly shaped containers, unlike single-item vending machines, and various product dispensing devices for vending machines have been proposed. (For example, Japanese Patent Publication No. 62-176892).

DESCRIPTION OF THE PREFERRED EMBODIMENTS A conventional product dispensing device for a vending machine as described above will be described below with reference to the drawings.

3 and 4 show a conventional product dispensing device of a vending machine. In the figure, 9 is installed on the inner surface of the side wall of the product storage device 1 facing the product stopper 8,
The product holding flapper 6 supports 3 base 7 and extends upward from the upper end surface of the lowest product 2 held by the product holding flapper 6 with the bottom end slightly above the product holding flapper 6.
9 has an appropriate thickness t, and forms a product passage width B corresponding to the width W of the product 2 in the product storage device 1. On the other hand, the product stonoper 8 is formed in a horizontal double-shape that extends outward from the lower leg 8a, and the horizontal portion 8b is located at or slightly below the same level as the lower end surface of the second product 20 from the bottom, Moreover, it is formed to be slightly shorter than the thickness t of the Nuvasa-9. In this case, the control cam 7 is arranged at a position where it comes into contact with the lower leg 8a of the product nutoper 8.

The operation of the product dispensing device for a vending machine configured as described above will be described below.

In the above-mentioned configuration, in the sales standby state, the products 2 in the left and right rows are piled up straight like the products 2 in the right row in FIG. It is in a hanging position. After entering the product sales state, the drive device 3 starts and the rotating shaft 4
starts rotating and reaches a rotation angle of 9o0, as shown in FIGS. 3 and 4, the left product stopper 8 is pushed out by the control cam 7, and its lower leg 8a stops the lowest product 2. is pushed out toward the side wall of the product storage device 1, and at the same time, the horizontal part 8b is inserted into the bottom side of the lower end surface of the second product 2 from the bottom, so that the product 2 in the second band is supported from below, and the second The product 2 and the product above it are restrained and held at the storage position.

When the second inspected product 2 is restrained and held, the product holding flapper 5 swings downward to open the product passage, and the lowest product 2 is dropped and carried out. When the rotating shaft 4 further rotates from here, the product holding flapper 6 is again restrained by the control cam 6 and returns to the horizontal position, and the products 1 to 8 that were restraining and holding the second product 2 are The restraint by the control cam 7 is released and the body returns to its free hanging position. As a result, the second and higher products fall all at once and are supported by the product holding flapper 6, and the rotating shaft 4 stops after 1800 flips, and the selling operation ends, and the product storage device goes into a standby state for selling together. Become.

5 Problems to be Solved by the Invention of the Vane However, in the above conventional configuration, the product holding flapper 5 swings downward to open the product passage, and the product holding flapper 6 is continuously restrained by the control cam 6 and placed in a horizontal position. Therefore, if the time that the product holding flapper 6 opens the product passage is shorter than the time for the lowest product 2 to fall and be carried out, the product 2 in the lowest rank will not fall and be carried out, and the product holding flapper 6 will This has the disadvantage that the lowest order product 2 is pressed against the parts storage device 1, deforming and damaging the lowest order product 2.

The present invention solves the above-mentioned conventional problems, and eliminates the unsold and deformed damage of the lowest-ranked products, and eliminates the problem of unsold and deformed products, and the products whose falling and unloading time is longer than the time during which the product holding flapper opens the product passage. To provide a product delivery device for a vending machine that reliably transports products even in such cases.

Means to Solve the Problem To achieve this objective, we will remove the product from the vending machine, attach the bamboo bar, and use the flapper to hold the product at a certain time.

Provided with a detection device for opening/stopping and its control device,
After the lowest product is dropped and carried out, the product holding flapper is configured to be closed after the lowest product no longer exists at the position of the product holding flapper.

With this configuration, when the product holding flapper is completely opened, the product holding flapper is stopped for a certain period of time by the operation of the detection device, the lowest product is dropped and carried out, and then the product holding flapper is closed to normally carry out the product.

EXAMPLE An example of the present invention will be described below with reference to the drawings. However, components that are the same as those in the prior art will be given the same numbers and detailed description thereof will be omitted.

FIGS. 1 and 2 show a product dispensing device for a vending machine according to an embodiment of the present invention. In the same figure, 1
0 is a detection device, which is placed at a position that follows the control cam 6, and detects the operation of the drive device 3 at a rate of 7. Reference numeral 11 denotes a control device which inputs a detection signal from the detection device 10 and controls the operation and stopping of the product holding flapper 5.

The operation of the product delivery device of the vending machine configured as described above will be described below.

First, in the sales standby state, the products 2 in the left and right rows are piled up straight like the products 2 in the right row in FIG. It's in the posture. After entering the product sales state, the drive device 3 is started and the rotating shaft 4 starts rotating, and when the rotation angle reaches 90', the product stopper 8 on the left side is stopped as shown in FIGS. 1 and 2. It is pushed out by the control cam 7, and its lower leg 8a pushes out the lowest product 2 toward the wall of the circle 1 of the product storage device 1, and the horizontal portion 8b is pushed out under the lower end surface of the second product 2 from the lowest. Get into the side 2
The second product 2 and the products 2 above it are restrained and held at the storage position by supporting the second product 2 from below. After the second product 2 is restrained and held, the product holding flapper 6 swings downward to open the product passage, and when the product holding flapper 5 is completely opened, the detection device 1o operates and outputs a detection signal. When the control sound device 11 receives the detection signal, the product holding flapper 6 is stopped for a certain period of time, during which time the lowest product 2 is dropped and carried out. After a certain period of time has elapsed, the rotating shaft 4 starts rotating again, and the product taste flapper 6 is restrained by the control cam 6 and returns to a horizontal position, and the product stopper 8, which was restraining and holding the second product 2, is restrained by the control cam 6. ] The restraint by the cam 7 is released and the body returns to its free hanging position. As a result, the second and higher products 2 fall all at once and are supported by the product holding flapper 6, and when the rotating shaft 4 rotates 180 degrees, it stops and the sales operation ends, and the product storage shelf returns to the sales standby state. .

As described above, according to this embodiment, the product holding flapper 6
By providing a detection device 1゜ and its control device 11 for stopping the product for a certain period of time, the unsold origin and deformation damage of the lowest product 2 are suppressed, and the time period during which the product holding flapper 5 opens the product passage is reduced. Even if the falling and unloading time of the product 2 is longer than that of the product 2, the product 2 can be reliably transported within 9 pages.

Effects of the Invention As described above, the present invention is provided with a detection device and a control device for stopping the product holding flapper for a certain period of time, so that when the product holding flapper is completely opened, the detection device stops the product holding flapper for a certain period of time. After the lowest-ranked product is dropped and carried out, the product holding flapper is closed, which eliminates tampering and deformation damage to the lowest-ranked product.
Even if the time it takes for the product to fall and be removed is longer than the time the product holding flapper leaves the door open, the product can be removed reliably, and its practical effects are astounding. .
