Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present application relates to a coin sorting device used in an article vending machine that sells articles by inserting coins or a money exchange machine that exchanges money.

<Prior Art> Conventionally, in a coin sorting device used in a goods vending machine that sells goods by inserting coins or a money exchange machine that exchanges money, small-diameter coins are simply passed through and guided in a desired direction, and medium-diameter coins are placed in a cradle. by holding and rotating it to guide it in other desired directions,
Furthermore, by retaining larger diameter coins, large,
For example, the sorting method for sorting medium and small coins was developed by Jikosho.
It is known from the publication No. 51-3033.

<Problems to be Solved by the Invention> However, conventional coins that are smaller than large-diameter coins and larger than medium-diameter coins and larger than large-diameter coins, that is, 500 yen coins that have the largest diameter among coins, At the time of issuance, there was no means of sorting out counterfeit coins that were smaller in diameter than the 500 yen coin but larger than the 10 yen coin, which is the largest of existing coins, and counterfeit coins that were larger in diameter than the 500 yen coin.

Of course, it is also possible to configure the above-mentioned sorting means using a conventionally known cradle, but in this case, counterfeit coins larger in diameter than 500 yen coins are retained, and coins smaller in diameter than 500 yen coins are passed through. At the same time, there is a first cradle that rotates while holding a 500 yen coin, and among the coins that have passed through the first cradle, a counterfeit coin with a diameter larger than a 10 yen coin is stopped, and a coin with a diameter smaller than a 10 yen coin is stopped. It is necessary to arrange the second cradle that rotates while supporting the 10 yen coin in two stages, and this configuration has the disadvantage that a large space is required for installing the sorting means.

<Means for solving the problem> Therefore, in this application, newly issued 500 yen coins that are larger than existing coins and all existing coins are sorted and guided to paths in different directions. , counterfeit coins larger than 500 yen coins, and counterfeit coins with a diameter between the 500 yen coin and the 10 yen coin, which is the largest existing coin, will be blocked from passing and placed directly under the slot. The system expands the sorting function by allowing the coins to stay there, and its gist is that it is attached to the back of the base frame below the inserted coins, and is normally pressed against the back side by a spring, while the return lever a mounting piece that rotates against the spring when operated; an intermediate portion rotatably supported on the mounting piece; and normally held vertically by a weight; The lower inner edge has an upwardly facing first folded piece and a sideways second folded piece that protrude toward the inner surface of the base frame and support a coin, and when a coin is supported by the first and second folded pieces, the A cradle that rotates in one direction against a weight and is restricted from rotating in the other direction, a limiting piece fixed to the mounting piece, and one end of which is rotatably pivoted to the limiting piece. and a rotating member whose upper and lower limits of its rotational range are regulated by the limiting member and which is normally held at the lower limit rotational position by a weight, the rotating member having: Protruding inward from the base frame, which faces the first folded piece at a required distance and acts with the inserted coin interposed therebetween to apply a rotational force to the rotating piece in the upper limit direction against the weight. A third folded piece is provided, and a fourth folded piece is provided, which acts on the cradle during its rotation toward the upper limit and restrains the rotation in one direction. In the case of coins, the rotating part rotates to the upper limit position, and the first folded piece and the third folded piece support and stop the counterfeit coin, so that the inserted coin has a smaller diameter than the genuine coin. In the case of counterfeit currency, the fourth
Rotation of the cradle in one direction is restrained by the folded pieces to hold and stop the counterfeit coin between the first, second and third folded pieces, and when the inserted coin is a genuine coin, the coin cannot be rotated. The cradle is characterized in that it is configured to allow free rotation of the cradle without being restricted by the rotation of the movable piece.

<Operation> According to the present application, when a counterfeit coin larger than a 500 yen coin is inserted, for example, the counterfeit coin passes between the first folded piece of the cradle, which faces directly below the insertion slot, and the rotating piece. The cradle and the rotating piece rotate in the direction in which the first folding piece and the third folding piece are separated, but the rotating piece is regulated at its upper limit rotational position, so
Due to this regulation and the regulation of the rotating direction of the cradle, the counterfeit coin is held between the first folded piece and the third folded piece and stopped at that position. Also, for example
When a counterfeit coin that is smaller in diameter than a 500 yen coin and larger in diameter than the largest existing 10 yen coin is inserted, the counterfeit coin will be placed in the first fold of the opposing cradle. Although it intervenes between the piece and the third folded piece of the rotating part, it falls without acting on the first folded piece and the third folded piece, and acts on the second folded piece of the cradle. This causes the cradle to rotate to one side of the rotating portion. The rotation of this cradle is stopped by the fourth folded piece of the rotating member on the way, so that the counterfeit coin is separated by the first folded piece, the second folded piece, and the third folded piece. It is supported and held in that position.

Furthermore, when a target specie coin, for example a 500 yen coin, is inserted, the genuine coin is inserted between the first folded piece of the cradle and the rotating piece while pressing the third folded piece of the rotating piece outward. The cradle is interposed between the third folded piece and acts on the second folded piece, and the cradle is rotated to one side of the rotating portion.
In this case, the rotating piece rotates a lot so that the fourth folding piece does not restrict the rotation of the cradle. Therefore, the cradle rotates a lot while supporting the specie coins and transfers the specie coins into the specie coins. lead to the passage.

Furthermore, in the case of existing specie coins, that is, specie coins with a diameter of 10 yen or less, it passes between the first folded piece of the cradle and the second folded piece of the rotating member without acting on them. At the same time, it acts with the second folding piece and is directed to another genuine coin passage.

<Examples> Examples of the present application will be described in detail below with reference to the drawings. The drawing allows the introduction of the new 500 yen coin, which has the largest diameter, and the existing coins, which are smaller in diameter, such as 100 yen, 50 yen, and 10 yen, into separate specie passages, and Counterfeit coins that are smaller in diameter than the new coins but larger than the 10 yen coin, which is the largest existing coin, and counterfeit coins that are larger in diameter than the new coins are to be prevented from being introduced into any of the genuine coin aisles.

The return lever 7 consists of an L-shaped rotating piece having one end pivotally connected by a shaft piece 37 and having a pressing piece 38 at the other end, and a restoring spring 39 is attached to this. 4
0 is a spring 39 for restoring the return lever 7.
A movable piece 41 that moves along the outer surface of the guideway board 35 when rotated against the rotation is located on the back surface of the base frame 1, and its upper end engages with the return lever 7 to lock the lever 7. It is a long operation piece that descends when rotated against the restoring spring 39, and has an inclined cam piece 43 protruding from one side edge thereof. Reference numeral 44 denotes an operating piece that is integrally hung down on one side of the mounting piece 15 and has a folding piece 45 at its lower end that comes into contact with the lower edge of the inclined cam piece 43, and is inclined when the operating piece 41 is lowered. The cam piece 43 pushes the mounting piece 15 outward, thereby causing the mounting piece 15 to rotate outward against the spring 14. 46 is a guide piece provided at the lower part of the guideway 36. Further, the opening/closing plate 5 includes a first
A second cradle 47 for receiving the existing coin P ₂ that has passed through the cradle 23 and guided downward by the inclined surface 34 of the guide piece 33 and guiding it to a predetermined path; A sorting magnet 48 for attracting fraudulent coins is provided as is known in the art, and when the return lever 7 rotates against the restoring spring 39, a part of the opening/closing plate 5 rotates against the restoring spring 39. It is pressed by the provided protrusion 49 and rotated away from the inner surface of the base frame 1 against the spring 6 . Reference numeral 50 denotes a stopper provided outward at the middle of the upper edge of the limiting piece 30 in order to abut against the upper edge of the rotating piece 32 and restrict the upper limit of its rotation.

However, as shown in Fig. 5, the first cradle 2
3 is in a vertical state due to the weight 16, with its rotation point 22 located directly above the weight 16, and the rotation member 32
is rotated to the lower limit position by the weight 29, and the short leg piece 28
When the folded piece 27 of the elongated leg piece 26 is in contact with the upper edge 30' of the restriction piece 30 and the folded piece 25 of the elongated leg piece 26 faces the coin drop position, a new coin _P1 is inserted from the slot 9. Then, the new coin P ₁ collides with the folded piece 25 of the long leg piece 26 facing the falling position and presses it outward, and the rotating piece 32
It rotates clockwise in the figure against the At this time, the diameter of the new coin P ₁ causes the rotating piece 32 to rotate significantly in the clockwise direction, and the new coin P ₁ presses the folded piece 25 outward as shown in FIG. 23 and the upper folded piece 18 and falls onto the side folded piece 21, the new coin _P1
The first cradle 23 is received by the folding pieces 18 and 21 of the cradle, and the weight of the new coin _P1 causes the first cradle 23 to rotate clockwise about the shaft piece 22 as shown in FIG. In this case, the short leg piece 2 provided on the pivot piece 32 rotates greatly.
Since the folded piece 27 of No. 8 passes over the vertical edge 19' of the cutout step 19, the first cradle 23
2, the new coin _P1 rotates sufficiently clockwise as shown in FIG. Passing through the passageway 36, the coin is led to the regular passageway for the new coin _P1 . Furthermore, when an existing coin P ₂ is inserted into the slot 9, even if the coin P ₂ temporarily contacts the folded piece 25, there is a sufficient gap between the folded pieces 18 and 25, While freely passing between
While the folded pieces 21 and 21' of the first cradle 23 prevent it from entering the guideway 36, as shown in FIG.
4 and guided onto the surface of the guide piece 33, and at this position, the second cradle 47 changes direction in the direction of arrow A and guides the existing coin _P2 to the regular passage.

Next, when the counterfeit coin P ₃ , which has a smaller diameter than the new coin P ₁ and a larger diameter than the existing coin P ₂ , is inserted through the slot 9, its outer circumference first contacts the folded piece 25, causing it to fall. is pressed outward, and the rotating piece 32 rotates clockwise against the weight 29.

However, since the diameter is smaller than the new coin P ₁ ,
The rotating piece 32 has a short leg piece 28 with a cutout step 19.
Therefore, sufficient rotation of the first cradle 23 is restricted by the abutment between the vertical edge 19' and the folded piece 27, as shown in FIG. So, fake coin P ₃ has fold pieces 18 and 2.
It is stopped directly below the input port 9 while being supported at three points 5 and 21. Furthermore, when a counterfeit coin P ₄ with a larger diameter than the new coin P ₁ is inserted into the slot 9, the folded piece 25 is pressed outward and the rotating piece 32 rotates more than in the case of the new coin P ₁ . do. Then, the rotating piece 32 moves to the 11th
As shown in the figure, the upper edge of the coin comes into contact with the stopper 50 to restrict the upper limit of its rotation, and as a result, the counterfeit coin _P4 is held between the folding pieces 25 and 18 and is prevented from passing between them. , also in this case, it is stopped directly below the input port 9. However, the counterfeit coins were stopped like this.
P ₃ and P ₄ are guided to the return passage 11 by pressing and rotating the return lever 7 against the spring 39. That is, when the return lever 7 is pressed and rotated, the operation piece 41 descends from the state shown by the solid line in FIG. Mounting piece 1
5 rotates in the rear direction, and the folding pieces 18, 21, 21', and 25 that were protruding from the inner surface of the base frame 1 escape from the inner surface. On the other hand, the opening/closing plate 5 is also pressed by the protrusion 49 and separated from the inner surface of the base frame 1, so that the counterfeit coins P ₃ and P ₄ fall due to their own weight and are guided to the return path 11. Note that the reversal (counterclockwise rotation) of the first cradle 23 is regulated by the collision between the end 17' of the opening 17 and the folding piece 18 or the collision between the upper edge 20' of the opening 20 and the folding piece 21. be done.

<Effects of the Invention> As described above, according to the present application, counterfeit coins that are larger in diameter than genuine coins (new coins) and counterfeit coins that are smaller in diameter than genuine coins but larger than existing coins are Since the structure is such that genuine coins and existing coins are allowed to pass through, they are kept in a suspended state regardless of their diameter, and the counterfeit coins are kept in a suspended state and removed by the return lever. This operation makes it easy to separate genuine coins from counterfeit coins. Genuine coins can be guided to the return aisle by rotating and non-rotating the cradle, making it easy to separate genuine coins from counterfeit coins. Since the structure leads to the following, it becomes easy to sort new coins from existing coins, and it is possible to provide a device with good sorting function.
