Description

[Detailed Description of the Invention] The present invention relates to, for example, a device for detecting the product storage state of a vending machine that sells packaged products.

Conventional devices of this type have a product-activated microswitch mounted at right angles to the side of the column. As a result, the side width of the column increases, making the entire aircraft larger.

The present invention aims to improve these points and provide a device that can be made thin and has reliable operation.

Next, an embodiment of the present invention will be described with reference to the drawings.

In Figure 1, 1 is a box with an opening at the front.
A hanging frame 2 is attached to the lower part of the upper wall of the box body 1, and an intermediate frame 3 is provided inside the hanging frame 2 so as to be movable in the front and rear direction, and a column 4 is opened on one side of the intermediate frame 3. is installed vertically so that it can move forward and backward. A spiral body 5 is rotatably supported vertically in the center of the column 4, and a motor 6 is connected to the upper part of the spiral body 5.

Then, the product 7 is mounted on the spiral body 5 inside the column 4, and the column 4 is housed in the box 1 via the intermediate frame 3.

In this state, when a coin is inserted into an operation mechanism (not shown) and the ejection button is operated, the motor 6 rotates the spiral body 5 by half a rotation, causing the product 7 on one of the front and rear sides to fall downward and guide it to the product sales outlet.

A detection device 11 is attached to the lower side of the column 4 as shown in FIG. As shown in FIGS. 2 and 3, this detection device 11 includes a support frame 12 provided on the side surface of a column 4.
A support plate 13 is fixed to the inside of the upper part of the support plate 1.
A switch frame 15 is attached to 3 with screws 14, a micro switch 16 is held on this switch frame 15, and an operating piece 17 of this micro switch 16 projects downward.

An operating lever 18 is provided at the bottom of the support frame 12. The actuating lever 18 has an actuating part 19 extending from its upper end, and a pressure receiving part 21 extending from its lower part via an inclined bent part 20. 22 into the column 4, and a bearing piece 23 is provided protruding from the outside of the upper part.
It is rotatably mounted on a support shaft 24, and furthermore, a spring receiving piece 25 is protruded from the outside of the upper part, and a coil spring 26 is stretched between this spring receiving piece 25 and the lower part of the supporting frame 12. There is.

Further, an intermediate lever 27 is rotatably supported on the support frame 12 between the switch 16 and the operating lever 18 by a support shaft 28 . This intermediate lever 27 has an operating piece 17 of the switch 16 at the top.
A mountain-shaped pushing part 29 is formed on the opposite side of the support shaft 28, and the actuating lever 1 is formed on the side opposite to the support shaft 28.
A contact portion 30 for contacting the actuating portion 19 of No. 8 and an inclined cam side portion 31 following the contact portion 30 are formed, and a stopper piece 32 is provided protruding from the cam side portion 31.

In such a configuration, product 7 is placed in column 4.
If there is, as shown in FIG. 3, the pressure receiving part 21 of the actuating lever 18 is pushed by the product 7 that is successively lowered, and the abutting part 30 of the intermediate lever 27 is in contact with the actuating part 19, Switch 16 is inactive.

Next, product 7 in column 4 is sequentially dispensed,
When the product is sold out, as shown in FIG. 4, the actuating lever 18 rotates clockwise in the figure due to the tension of the spring 26, and the actuating portion 19 pushes the cam side 31 of the intermediate lever 27, causing the intermediate lever 27 to move. 27 in the clockwise direction in the figure, and the push part 29 pushes the switch 16.
The operating piece 17 is pushed to operate the switch 16 to operate a display device (not shown).

At the same time, the actuating portion 19 of the actuating lever 18 comes into contact with the stopper piece 32 of the intermediate lever 27, and the rotation of the actuating lever 18 and the intermediate lever 27 is limited to a predetermined angle.

In addition, although the above example shows a column having a product delivery mechanism using a spiral body, the column is not limited to this type of column, and how can it be used for columns in which products are stored in a row, such as a stacking type of products? It can also be used for things.

Furthermore, it can be used not only vertically as shown in the figure, but also horizontally.

Furthermore, if the intermediate lever is vertical, it can be of the self-return type, but the return operation can be ensured by attaching a return spring.

In addition to detecting sold-out items in vending machines, it can also be widely used for detecting products.

According to the present invention, since the movement of the operating lever is transmitted to the switch via the intermediate lever, the switch can be set freely, the switch does not particularly protrude, and it can be made thin.

In addition, when the operating lever rotates by a predetermined angle, it comes into contact with the stopper piece of the intermediate lever and stops.Therefore, the operating lever does not rotate and protrude more than necessary, and the intermediate lever also stops rotating. , without pushing the switch operating piece more than necessary.
Can be used safely.
