Description

[Detailed Description of the Invention] Industrial field of application The present invention relates to a product unloading device in an automatic vending machine for cans, bottles and the like.

2. Description of the Related Art In recent years, there has been a demand for an automatic vending machine that can sell a wide variety of products and products in irregular shapes.

Hereinafter, an example of a product unloading device in a conventional product vending machine will be described with reference to FIGS. 4 to 7. In the figure, reference numeral 1 is a product storage shelf, which is provided with guide plates 2 and 3 at the front and rear thereof, and two pairs of sprockets 4 and 4'are rotatably supported at both ends thereof. Two chain belts 5, 5'are wound around the sprockets 4, 4'in parallel and stretched. One sprocket 4 is connected to a product discharge drive motor 7 via a shaft 6. Also, chain belt
Tracks 9 on which the products 8 are placed are attached at predetermined intervals between 5, 5 '. On one side of the guide plates 2 and 3 and on the carry-out side 10, there is a U-shaped detection lever 11 in the front-rear direction of the product storage shelf with the shaft 6 as the center of rotation. At one end 12 of the detection lever 11, a rotation preventing member 13 having one semi-circular claw is coaxially formed, and
A control member 16 is formed which comes into contact with the claw portion and comes into contact with a position detection member 15 which moves left and right by vertical movement of the bucket 14 and which is rotatable about one point. An arcuate actuator 17 is formed on the detection lever 11, and a switch 18 for stopping the drive motor 7 is fixed on the extension of the actuator 17. Further, 19 is a spring, which is attached coaxially with the rotating shaft of the detection lever 11, and pushes the detection lever 11 in the direction opposite to the detection port side 10. 20
Is a mounting plate which holds the position detecting member 15 and the control member 16 and is mounted on the product storage rack 1.

The operation of the product discharging device of the vending machine configured as described above will be described below. When the bucket 14 moves to the selected product storage rack 1 in response to the carry-out signal, the position detection member 15 operates, the drive motor 7 rotates, and the sprocket 4 moves the chain belts 5, 5 ',
The caterpillars 9 are sequentially placed on the guide plates 2 and 3, and the carrying-out side 1
Pushed to 0. At this time, the products 8 on the track 9 are also sequentially sent to the carry-out side 10. And product 8
Immediately after transferring from the carry-out side 10 to the bucket 14 from the product storage rack 1, immediately after the product 8, the detection lever 11 is pushed and rotated, and a switch is made by an arc-shaped actuator 17 formed on the opposite side of one end 12 of the detection lever 11. Press 18 and stop the drive motor 7 in response to the signal to finish the delivery of the product 8. Then, the bucket 14 on which the delivered product 8 is placed descends, and the product is delivered. The detection lever 11 is returned to the original position by the spring 19 after the product 8 has been over the bucket, the rotation preventing member 13 rotates, the control member 16 is pushed up, the claw portion is locked, and the waiting state for the next unloading is set.

However, in the conventional configuration as described above, the problem shown in FIG.
When the product 8 as shown in FIG. 7 is stored in the product storage rack 1, the product 8 is stored in contact with the U-shaped detection lever 11.
At this time, the rotation prevention member 13 coaxial with the detection lever 11
, But abuts the control member 16 and is locked. And it is waiting in this state. Next, when the product in another product storage shelf is sold by the sales signal, the bucket 14 moves up and down, and the bucket 14 moves the position detection member 15 of each product shelf left and right, so that the control member 16 is rotated. Therefore, the detection lever 11 is unlocked. At this time, if the product 8 placed on the caterpillar 9 rides on the ribs of the caterpillar 9 and is in an unstable state, it slightly moves or rotates to the carry-out side 10 and the tip of the control member 16 prevents rotation. It does not come into contact with the member 13. Because of this, the lock becomes difficult. When the next product is stored in this state, the product pushes the detection lever 11 and moves and drops toward the carry-out side 10, causing the product to be damaged or scratched.
In addition, even though the bucket 14 does not sell when moving
There was a problem of dropping to 14 and discharging two.

In view of the above-mentioned problems, the present invention, even when a product is stored while abutting against a detection lever, the product may move to the carry-out port side or fall when the product is not sold, regardless of the vertical movement of the bucket.
It is intended to provide a product unloading device for a vending machine that does not cause two unloading.

Means for Solving the Problems In order to solve the above problems, a product unloading device for a vending machine according to the present invention includes a release member that is rotatable in conjunction with a position detection member, and a control member that is rotatable in contact with a rotation prevention member. And a detection switch for detecting the opening and closing of the door, and the chain belt is reversed by the operation of the detection switch.

The present invention has the above-mentioned configuration so that the product is housed so as to contact the detection lever when the product is filled, but after the product is filled, the detection switch detects that the door is closed,
It reverses in the direction opposite to the exit side, does not come into contact with the detection lever, and the product does not fall.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT An article carrying-out device for a vending machine according to an embodiment of the present invention will be described below with reference to the drawings.

1 to 3 show a product unloading device for an automatic vending machine according to an embodiment of the present invention, the same components as those of the conventional example are designated by the same reference numerals and the description thereof will be omitted.

In FIG. 1, a detection switch 17 for detecting opening / closing of a door is provided on the product storage shelf 1 and a lower portion thereof.

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

In FIG. 2, when the product is filled, the detection lever 11 is locked by the control member 16 and the product 8 is detected by the detection lever 11.
Is housed so as to abut. When the door 18 of the vending machine is closed, the detection switch 17 is actuated, the electrodes supplied to the motor 7 are replaced, and the reverse direction is reversed in the direction opposite to the carry-out side 10, and the product 8 moves to a position where it does not contact the detection lever 11. Then it will be in a sales standby state.

As described above, according to the present embodiment, the product does not come into contact with the detection lever, and it is possible to prevent the product from dropping even if the other product storage shelves are unlocked at the time of sale.

As described above, according to the present invention, the position detection member, the detection lever,
By providing a rouge-shaped anti-rotation member that is provided coaxially with the detection lever to stop rotation, a control member that is rotatable in contact with the anti-rotation member, and a detection switch that detects opening and closing of the door, By reversing the product storage shelves by the operation of the detection switch, it is possible to prevent contact with the detection lever after the products are stored, and prevent problems such as non-sale products falling and product damage due to movement of the bucket.
