Abstract

Disclosure of the Invention To provide a coin sorting device that can be effectively sorted by different diameters even in coins having substantially the same magnetism.

The cylindrical magnet 5 is provided in the exit part 4 which is the left end part of the structure coin guide part 3, and inverts a coin to the lower right direction. The reversed coin pushes down the detection lever 8 protruding from the first hole 6 installed at a position spaced apart from the outlet at a distance substantially the same as the diameter of the coin, and is connected to the detection lever ( Push 9) down again. The shutoff lever always protrudes in the coin passage 3 via the second hole 7 in the vicinity of the outlet, and only when the detection lever 8 is embedded, the second hole 7 is embedded. For this reason, the pseudo-coin with a small diameter cannot push down the detection lever 8, so that the blocking lever 9 is not buried, and it protrudes in the coin passage 3 and blocks the reversed coin passage.

Industrial use

The present invention relates to a coin sorting device for sorting coins, and more particularly, to a coin sorting device for sorting coins having the same magnetism and different diameters in coins used in game machines and the like.

Therefore, the concept of coin in this specification includes hard currency inside and outside, metal for game, token, etc.

Conventional technology

Conventionally, a coin sorting device of this kind has a substantially cylindrical one magnet piece at an outlet end of a passage bottom plate through which coins are driven, as described in Japanese Patent Application Laid-Open No. 54-74597.

As the magnet piece, curing made of non-magnetizing materials such as brass, copper, and aluminum, for example, 100 won, is passed through the magnet piece as it is without being influenced by the adsorption force of the magnet piece, and true curing is selected.

Therefore, counterfeit coins such as iron are rotated around the magnet piece by suction and self-weight due to the suction force of the magnet piece so that the traveling direction is reversed. The pseudo coin was returned to the return hole.

In the case of a game coin having magnetization, only true metal coins are sorted by using magnetization as opposed to the coin sorting apparatus described above.

However, in the case of a metal or coin having substantially the same magnetism, there is a problem that even if the diameter is large or different, the metal or coin is selected as a true metal or coin.

Challenge to devise

The present invention has been developed for the purpose of solving the above-mentioned problems.

In other words, even if the coin has essentially the same magnetism, it is to provide a useful coin sorting device that can distinguish the case of the coin diameter.

Means to solve the problem

The present invention provides at least an inlet through which a certain coin having magnetism can pass, a guide path for guiding coins from the inlet, a magnet provided at an outlet of the guide path, and a downward opening of the magnet. A first hole, a second hole opened at a radial distance of the coin in the transverse direction of the first hole, a coin detection lever capable of being sunk in the guideway from the second hole, and a first interlocked with the detection lever. The present invention relates to a coin sorting device having a coin blocking lever that can be mounted in a guideway from a hole.

The present invention also relates to a coin sorting device in which the detection lever is movably disposed with respect to the blocking lever.

Action

Therefore, according to the present invention, the true coin of the magnet having a predetermined diameter is converted to the drop direction due to the magnet provided at the outlet of the lower side of the guideway.

At this time, since the true coin is in contact with the detection lever, the detection lever and the interlocking lever are pulled away from the guide path so that the true coin whose direction is changed is not blocked by the blocking lever but falls in a predetermined direction.

On the other hand, a counterfeit coin having a diameter smaller than a predetermined coin diameter, that is, a pseudo coin is changed in the falling direction by a magnet provided at the outlet of the lower side of the guideway, and at the same time, the pseudo coin does not contact the detection lever. Since the interlocking blocking lever is not blocked from the guideway, the pseudo coin is blocked by the blocking lever and falls as it is.

By this, even if the coin has magnetism, coins whose diameter is smaller than a predetermined value can be reliably excluded.

Example

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

1 is a schematic perspective view showing a mounting state of an embodiment of the present invention, and FIG. 2 is a schematic cross-sectional view seen from the left side of FIG.

First, the coin sorting apparatus in the present embodiment will be described.

The coin sorting device has a movable plate 1 and a fixed plate 2 that face each other in parallel with a constant gap, as shown in FIG.

1, a coin inlet is not shown on the right side of FIG. 1 upward.

The coin inlet is defined, for example, with a predetermined diameter (eg 21.25 mm) and thickness (eg 1.9 mm).

Therefore, a coin inlet not shown will only allow coins below the specified dimensions to pass therethrough.

In addition, in the case of FIG. 1, the coin guide path 3 is arranged inclined substantially along the lower left direction of FIG. 1 from substantially perpendicular of the coin inlet.

In other words, the coin guide path 3 is rotated from the coin up into the left downward from the upper right of FIG.

Moreover, as shown in FIG. 1, the cylindrical magnet 5 is provided in the exit 4 which is the lower left side of the guide path 3 of a coin.

Therefore, in FIG. 1, the true coin of magnetism which is transmitted toward the lower left is changed in the advancing direction toward the outer circumferential direction of the cylindrical magnet 5 by the attraction force, and as a result, is reversed to the right downward in FIG.

As described above, the inverted magnet of true magnetism overcomes the suction force of the cylindrical magnet 5 by its own weight and kinetic force, falls down to the right downward in FIG. 1, and is stored in the receiving port (not shown) of the true coin.

In addition, in FIG. 1, the pseudo-coin without magnetization that is driven toward the lower left side does not change the direction of travel because the suction force is not applied, and as a result, it falls down just below the left side of FIG. Is returned to the sphere.

In the above-described coin sorting apparatus, as shown in FIG. 1, the fixing plate 2 is provided at a position near the outlet 4, in other words, the first hole 7 is drilled in the lower portion of the magnet 5. It is.

In addition, as shown in FIG. 1, the fixing plate 2 has a second hole 6 with a distance (21.25 mm) substantially equal to the diameter of the true coin of magnetism at a position spaced to the left from the outlet 4. It is installed in the perforated state.

In addition, on the outer surface side of the fixing plate 2, as shown in FIG. 1, a slightly long L-shaped lever connecting plate for connecting the detection lever 8 having a sharp bottom and the blocking lever 9 having an L-shaped bottom is connected to each other. (10) is installed.

In addition, a cross-shaped mounting plate 21 is shown in FIG. 2, and the upper and lower ends are fixed to the fixing plate 92, and the left and right ends are bent outwardly, and the detection lever 8 and the blocking lever are interposed through the main shaft 22. (9) and the lever connecting plate 10 is attached so as to rotate.

The tip 11, which is the lower end of the rotatable detection lever 8, always protrudes into the coin guide 3 through the second hole 6, and only when the coin reversed by the magnet 5 meets the coin guide. It is supposed to come out from (3).

In addition, the tip portion 12, which is the lower end of the rotatable blocking lever 9, always protrudes into the coin guide path 3 through the first hole 7, and guides the coin only in conjunction with the detection lever 8 ( It is supposed to come out from 3).

Therefore, the true coin of magnetism having a regular diameter is moved downward downward on the right side in FIG. 1 by adsorption of a cylindrical magnet 5 provided near the outlet 4 of the coin lane 3. Is reversed.

That is, the tip end portion 11 of the detection lever 8 protruding from the second hole into the coin guide path 3 fits into a true coin having a regular diameter and is the second hole (outside the coin guide path 3). 6) are moved into.

As a result, as shown in FIG. 1, the true magnetized coin reversed to the right downward passes through the tip portion 12 of the moving lever 9 and moves downward downward along the outer periphery of the cylindrical magnet 5. Move.

The true coin moved in the right direction in FIG. 1 overcomes the attraction force of the cylindrical magnet 5 by its own weight and kinetic force and falls to be stored at the receiving inlet (not shown) of the genuine coin.

On the other hand, the magnetizable pseudo-coin having a diameter smaller than the predetermined diameter is inverted from the transmission toward the left downward in FIG. 1 to the right downward by the cylindrical magnet 5, but the tip 11 of the detection lever 8 is small because the diameter is small. ) Does not occur.

As a result, the distal end portion 12 of the blocking lever 9 does not move into the first hole 7 but blocks the passage of the reversed magnetizing pseudo coin while protruding into the coin guide path 3.

Such magnetized coins fall to just below the left side in FIG. 1 and are returned to a return port (not shown).

Therefore, even if the coin is attracted to the cylindrical magnet 5, the pseudo coin having a diameter smaller than the normal coin diameter is blocked by the blocking lever 9 and excluded.

In the case of the non-magnetizing pseudo coin having a regular diameter, the suction force of the cylindrical magnet 5 installed near the exit of the coin guiding path 3 is not activated, so it falls down just below the lower side of FIG. 1 and returns to an unshown return port. do.

That is, the tip 11 of the detection lever 8 protruding from the second hole 6 into the guide path 3 abuts the pseudo coin having a regular diameter and is the second outside of the coin guide path 3. The suction force of the magnet 5 does not work even if it moves into the hole 8 and the tip 12 of the blocking lever 9 moves into the first hole 7 outside the guide path 3 in conjunction with the movement. Thus it falls just below the left side of FIG. 1 and returns to the return port, not shown.

In addition, as shown in FIG. 1, the lever connecting plate 10 is provided with an adjustment long hole 13 in a perforated state.

In the long hole 13, the bending piece 14 of the upper end side of the detection lever 8 is slidably arrange | positioned, and the position of the detection lever 8 can be adjusted according to the diameter of a true coin, and arbitrary true The coin can be brought into contact with the tip portion 11.

In addition, the detection lever 8 and the blocking lever 9 which are not shown are interposed through the lever connecting plate 10, and are integrally connected with a screw or a piston.

In addition, although the magnet 5 of this embodiment has a cylindrical shape, it is not necessary to necessarily have a cylindrical shape.

In addition, the number of magnets 5 and the values of magnetic flux density may also be appropriately modified according to the physical quantity such as the weight of the coin, magnetism, and the like.

As described above, according to the present invention, since the falling direction of the magnetized coin can be controlled according to the diameter of the coin, even if the coin has substantially the same magnetism, it is possible to effectively select the coin according to the size of the diameter. It is possible to provide a large coin sorting device.
