Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vending machine having a structure in which a product can be reliably carried out and its outer shape is thin.

[0002]

[Prior Art and Problems to be Solved by the Invention] An automatic vending machine that sells products such as cigarettes has products stacked on top of each other.
It is general to push out one by one from the lower part and sell the specified product. Such a method is
It is convenient to stock the goods and also to fill the goods for stock. Furthermore, it can be said that the storage efficiency of the stocked products is good, and it is an extremely rational configuration when a plurality of kinds of products are sold and a large number of stocks are secured for each.
However, a vending machine having such a structure is also required to have a more rational structure, and particularly when the vending machine is installed on a passage or a road, the vending machine may project to a portion where people pass. , It was desired to be housed inside the building or to have an extremely thin structure. Therefore, although it is the most preferable method to store the vending machine in the building, it was not possible to easily store the vending machine because the structure of the building and the external dimensions of the vending machine were not constant. Therefore, it has been a big problem to make the vending machine itself as thin as possible.

In a conventional vending machine, a large number of products 101 are stacked on a base 102 as shown in FIG.
The column 103 keeps the stacking state and guarantees the inventory. Then, the product 101 on the base 102 has an unloading lever 105 of a belt 104 that rotates as shown by an arrow in the figure.
Is configured to be pushed out from the opening 106 formed in the lower portion of the column 103 and carried out.

In such a structure, in addition to the stock size of the product 101 formed by the column 103, the space size 107 necessary for pushing out the product 101 is required to be the same as the product 101, and the space of the product 101 is required. At least twice the size of the product 101 is required in the extrusion direction. For this reason, it was inevitable that the vending machine would have a structure that largely protrudes on the road. Even in such a structure, in order to make the thickness as thin as possible in the pushing direction, it is attempted to reduce the space dimension 107 by forcibly correcting the posture of the product 101 pushed from the column 103 downward near the opening 106. There is. However, these efforts
Product 10 that is inevitably damaged and is delivered
There was also an obstacle that 1 could not be carried out properly at the part where the posture was corrected and it got stuck.

The present invention has been made in view of such circumstances, and since the vending machine is structured so as to be formed thin so as not to project on the road, the vending machine becomes thin in the pushing direction. It is an object of the present invention to provide an automatic vending machine configured as described above and having a structure capable of reliably carrying out and selling products.

[0006]

According to the present invention, a product to be stacked is surrounded by a column and placed on a slide, and a cam that makes one rotation under the slide is provided, and the other side of the slide is pivotally mounted. The slide is tilted by the rotation of the cam when the cam is driven by the cam, and the second piece of the product placed on the slide is pressed against the inner wall of the column. Is provided on the other side of the slide, and one end of the lever is configured to be driven by the cam to drive the pressing operation, and the cam action process of this cam is performed to extend the pressing operation time of the lever. In addition, the tilting operation of the slide is configured to be operated during the operation of the lever.

[0007]

When the cam rotates to sell the product, the lever pushes the product in the second stage from the bottom against the inner wall of the column and clamps it. Then, the slide slides with the rotation of the cam, and the first stage product is dropped from the lower portion in the inclination direction.
At this time, the first stage product falling from the lower part and the second product from the lower part located above the lower part are separated and only the first stage product is carried out, and the slide is in the horizontal state, that is, the initial state. When it returns, the lever returns, and the second product that was pressed against the column and clamped is stopped and the second product is dropped on the slide that has returned to the horizontal state.

The cam action process lengthens the pressing operation of the lever, and the slide slides back once by tilting during the pressing operation of the lever. Therefore, for the second product from the bottom, the slide is below the slide. While the first product is being carried out, the second product is continuously pressed against the column from the lower side to be supported.

Embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a vertical sectional view showing an outline of the structure of an automatic vending machine according to an embodiment of the present invention. FIG. 2 is a vertical cross-sectional view showing a main part of the carry-out device. FIG. 3 is a vertical cross-sectional view of the main parts showing the operation of the carry-out device. FIG. 4 is a front view of the carry-out device. FIG. 5 is an exploded perspective view of a main part for explaining the structure of the carry-out device.

In FIG. 1, an automatic vending machine comprises an outer box 1, a door 2 that can be opened and closed, and a lower installation table 3.
A column 4 for accommodating and stocking products is provided inside, and a carry-out device 5 is provided below the column 4. And
In the lower part of the carry-out device 5, a space 7 for guiding the product carried out from the carry-out device 5 to the outlet 6 is formed. On the door 2 side, a display shelf 8 capable of displaying products and a money handling machine 9 capable of charging money are provided.

In FIG. 2, the carry-out device 5 of the vending machine is shown.
Has a column 4 capable of accommodating and storing the products 10 and 11 in a stacked state, and the operating portion of the carry-out device 5 is provided below the column 4.

The operation part of the carry-out device 5 is provided with a slide 12 which is a substantially L-shaped product receiving stand which stands by in a horizontal posture so that the product 10 can be placed thereon. The cam 13 is pivotally mounted on the other side so that one side is inclined downward about 45 degrees via the link 14 by the rotation of the cam 13. The inclination of the slide 12 is such that while the cam 13 makes one rotation, the slide 12 is inclined by the rotation of the cam 13 via the connecting action point 15 of the link 14 connected to the slide 12, and the maximum inclination. The angle is about 45 degrees. This tilt is configured so that the cam 13 makes one reciprocation by one rotation and tilts from a horizontal state by about 45 degrees, and returns to a horizontal posture again.

Further, the slide 12 is attached to the shaft mounting portion of the slide 12.
A lever 16 which pivots separately is provided, and the lever 16 is driven by the rotation of the cam 13. The driving of the lever 16 is performed via the acting portion 17 that follows the cam surface formed on the outer periphery of the cam 13, and the pressing portion 18 attached to the tip end portion of the lever 16 causes the second product 11 from the bottom. Is pressed against the inner wall of the column 4 so as to be clamped.

The cam surface of such a cam 13 is a slide 12.
Also, an operating portion is formed for operating the lever 16, and a protrusion 19 is formed on a part of the outer periphery of the cam 13 for operating the lever 16. The protrusion 19 causes the operating portion 17 of the lever 16 to operate. The pressing operation of the product 11 is temporarily stopped. That is, the pressing operation of the lever 16 is performed in a portion other than the projection 19, and the smaller the range of the projection 19, the longer the pressing operation time. Further, the slide 12 is connected to an action point 15 of the slide 12 by a link 14, and the cam 13
The slide 12 is tilted once with the rotation of and is returned to the horizontal state again.

The operation of the lever 16 and the slide 12 is such that the lever 16 presses the product 11 for a long time, and during that time, the slide 12 operates in a time shorter than the operation time of the lever 16. Has been done. And
A micro switch 20 acting on the cam 13 is provided, and the micro switch 20 is configured to operate by a cutout portion 21 formed on the outer peripheral surface of the cam 13.

The lever 16 is driven by the cam 13 so as to press the commodity 11, but is pushed by the spring 22 so as to be slid along the outer periphery of the cam 13.

In FIG. 3, the carry-out device 5 is constructed such that the cylindrical cam 13 is rotated by an electric motor (not shown) or the like, and the lever 16 is rotated by the rotation of the cam 13.
Is operating to press the product 11 against the column 4,
In the meantime, the slide 12 is inclined so that the commodity 10 is slid as shown by an arrow in the drawing and carried out. The other side of the slide 12 is formed by bending the slide 12 into an L-shape, and the slide 12 is pivotally mounted on the other side by a pin 25 and is tiltable.

In FIG. 4, on the front of the carry-out device 5, products 10 and 11 are stacked inside the column 4, and the products 10 and 11 are enclosed so that the stacking posture does not change. It is configured to be able to. The cam 13 is formed in a drum shape and is configured to be rotated once by the electric motor 26.

In FIG. 5, the carry-out device 5 includes a slide 12
Is a bent steel plate.
Is made of a resin molded product. And cam 13
Is formed of a resin molded product, and is configured to slowly and continuously make one revolution by an electric motor (not shown).

In such a structure, when the vending machine performs a selling operation in a state where the commodities 10 and 11 are stored in the column 4 in stock, a processing signal of the cash processing machine 9 or the like is controlled by a control device (not shown). When a sales instruction is issued by, the cam 13 is rotated once by the electric motor 26. Then, by one rotation of the cam 13, the lever 16 first operates to push the second product 11 from the lower part to clamp it between the inner wall of the column 4 and the slide 12 tilts to one side. As shown in FIG. 3, the commodity 10 placed on the table is slid to one side and carried out. Such an operation is different from the conventional vending machine in which the lowermost product 10 placed on the slide 12 is pushed out in the carry-out direction, so that the slide 2 can be dropped to the bottom of the column 4 due to the inclination of the slide 12. Since the product 10 is unloaded, a large space for unloading the product 10 is not required.

Therefore, the size in the carry-out direction can be reduced, and the size of the vending machine in this direction can be reduced. Therefore, it is possible to configure a vending machine having a thinner shape than that of a conventional vending machine that jumps out of the road.

In the case of the figure, the product 10 that slides down from the slide 12 has the bent portion 23 of the lever 16 projecting onto the slide 12 and lifts the other side of the product 10, which makes it easier to slide down because it is more inclined. Also, slide 12
It is possible to prevent the product 10 from coming into close contact with the upper surface of the product 10 and to prevent the sliding condition from being deteriorated, and the product 10 can be reliably slipped off the slide 12.

The operation of the unloading device 5 as described above is performed in the process of rotating the cam 13 by the link 14 and the lever 16 which are driven by the cam 13, and the product 1 inside the column 4 is
It is possible to reliably carry out 0 and 11 one by one. In addition, since the drive source that can reliably carry out each one in this way is performed by the electric motor 26 via the cam 13, it is easy to electrically control, and particularly, the rotation speed of the stepping motor or the like can be surely and easily controlled. By using the electric motor 26, easy and accurate control of unloading can be expected.

The slide 12 can be returned to the horizontal initial state by the rotation of the cam 13 when tilted by about 45 degrees. At this time, the lever 16 is also returned to the initial state by the slide 12 and the cam 13. In order to
The pressing of the product 11 against the column 4 is released. Therefore,
Product 11 held between lever 16 and column 4
Falls on the slide 12 that has returned to the horizontal state and is in a standby state. In this way, the products 10 and 11 can be carried out from the column 4 from the bottom and sold for sale.

The rotation of the cam 13 can be controlled by detecting the position of the cam 13 by the micro switch 20, and the electric motor 26 is constituted by a stepping motor or the like whose rotation speed can be easily controlled. Even in this case, the rotational position of the cam 13 may be calculated and controlled from the rotational speed. Since the vending machine generally has a microcomputer incorporated therein for controlling sales, such control can be easily performed without difficulty.

[0026]

According to the present invention, the space dimension required in the carry-out direction can be made extremely small by carrying out the products stacked on the slide, and the product carry-out direction of the vending machine, that is, It is possible to obtain a vending machine with a thin shape that does not project onto the road, and it is possible to configure an vending machine that can reliably pull out each item from the column and carry it out. Is extremely large in constructing a thin vending machine.
