Description

  The present invention relates to a coin sorting device, and more particularly to a coin sorting device that sorts one type of coin employed in a simple game machine or the like.

In the coin sorting device, when a diameter size, weight, thickness, and the like are different from those of a regular coin, the coin is sorted out as a false coin. In such a coin sorting device, a cradle (oscillator) is disposed downstream of the coin passage, and an engagement piece (protrusion) having an interval smaller than the diameter size of the regular coin is provided on the cradle. Is formed, and the engagement piece is disposed below the coin passage (see, for example, Patent Document 1).
In this coin sorting device, the regular coin is received by the engagement piece, whereby the cradle (oscillator) is swung and discharged to the regular coin discharge path, and the coin having a diameter smaller than that of the regular coin is the engagement piece. It passes through the gap and is discharged into the fake coin discharge path.

Japanese Utility Model Publication No. 61-180362 (see FIGS. 1 to 5)

By the way, in the coin sorting device of Patent Document 1, even in the case of a fake coin having a diameter smaller than that of a regular coin, there is a possibility that the cradle may be swung when it falls and collides with one engagement piece. A bifurcated rotation control operation lever having a pivot is attached, and the operation lever prevents the cradle from being instantaneously rotated, whereby a false coin having a small diameter is discharged to the regular coin discharge path. Is preventing.
Therefore, the coin sorting device disclosed in Patent Document 1 has a complicated structure, which increases the size of the device and increases the cost.

  The present invention has been made to solve such problems, and an object of the present invention is to provide a coin sorting device that can reliably sort regular coins and fake coins with a simple structure.

The present invention provides a coin introduction portion having a shape that prevents introduction of a fake coin having a diameter larger than that of a regular coin, and a coin introduction portion that is provided at a subsequent stage of the coin introduction portion and is orthogonal to an end face of the coin introduced from the coin introduction portion. A coin sorting device including a pendulum configured to be rotatable about a predetermined axis extending in a direction, wherein the pendulum can capture a regular coin inserted from the coin introducing portion at an eccentric position. The coin receiving portion is configured to pass a fake coin having a diameter smaller than that of a regular coin, and the pendulum is rotated by a predetermined angle in one direction with the weight of the captured regular coin. The genuine coin is dropped from the coin holder by the rotation of the pendulum and guided to one place, and a false coin having a diameter smaller than the regular coin is introduced into the coin. Characterized in that it is configured to direct elsewhere to pass through the emission received. In this case, it is preferable that the coin introducing portion has a shape that prevents insertion of a fake coin having a thickness dimension larger than that of the regular coin. Further, “one place” is a regular route, and “other place” is, for example, a return route.
Here, the “coin introduction part” is used in the claims and the description as a concept including not only a coin passage but also a coin insertion slot.

  Further, two plates are provided which face the opposite end faces of the coin introduced from the coin introduction part, and which separate the coin introduction part and operate in directions away from each other by operation of an operation lever. The pendulum is attached to one of the plates, and the pendulum is configured not to rotate or to rotate insufficiently depending on the weight of the fake coin in the case of a fake coin that is lighter than a regular coin. And the coin receiving part is configured by two protrusions that support two points on the outer periphery of the regular coin and capture the genuine coin, and one of the two protrusions that is near the outer periphery of the pendulum. The protrusion is configured to inhibit the circulation of coins to the one place regardless of the contact and separation of the two plates when the pendulum does not rotate or is insufficiently rotated. When the two plates are separated from each other, a gap larger than the thickness dimension of the regular coin is formed between the tip of the other protrusion and the other plate. When a two-plate operation is performed in a direction away from each other, a lighter coin than a regular coin is guided to the other place from a gap formed between the tip of the other protrusion and the other plate. Is preferred.

  Further, the regular coin is a non-magnetic material, and a magnet that normally faces the coin introduction path and captures the false coin that is a magnetic material is provided, and the magnet separates the two plates from each other by operation of the operation lever. It is preferable to move to a position outside the coin path when operated in the direction to move the fake coin, which is a magnetic body, to the other place from the gap formed between the pendulum and the other plate.

  Further, a gap smaller than the thickness dimension of the regular coin is formed between the tip of the other projection and the other plate, and a false coin having a smaller thickness dimension than the regular coin is inserted into the other projection. It is preferable that the gap between the tip of the plate and the other plate is passed through and guided to the other location.

  According to the present invention, by coining the shape of the coin introduction portion, installing the pendulum, and contriving the configuration of the coin receiving portion, it is possible to sort regular coins and fake coins whose diameter dimensions are different from those of regular coins. Therefore, a simple and inexpensive coin sorting device can be realized.

  In the case of fake coins that are lighter than regular coins, the balance of the pendulum is devised so that the pendulum does not rotate. Since this is eliminated by increasing the distance between the opposing plates, a simple and inexpensive coin sorting device can be realized in this respect as well.

  Further, when the genuine coin is a non-magnetic material and a magnetic false coin is excluded, the false coin is captured by a magnet, and the captured false coin is divided between a plate provided with a pendulum and a plate opposed thereto. Since this is eliminated by widening the interval and releasing the adsorption by the magnet, a simple and inexpensive coin sorting device can be realized also in this respect.

  Also, when removing false coins whose thickness is smaller than that of regular coins, the clearance between the tip of the other protrusion and the other plate is passed through and removed to another location. Is unnecessary, so it becomes more convenient.

Hereinafter, a coin sorting device according to the present invention will be described with reference to the drawings.
1 is a perspective view showing the front side of the coin sorting device according to the present invention, FIG. 2 is a perspective view showing the back side of the coin sorting device according to the present invention, and FIG. 3 is a sectional view taken along line IV-IV in FIG. 4 and FIG. 4 are views taken along the arrow V in FIG. 1, and FIGS. 5 to 9 are schematic diagrams for explaining the functions of the coin sorting device shown in FIGS.

  In this coin sorting device 1, a case 2 is composed of a case main body 2a and a plate 2b supported on the case main body by a shaft 3 so as to be freely opened and closed. As shown in FIG. 1, the plate 2 b is urged in the closing direction by the urging force of the torsion coil spring 4 wound around the shaft 3, and the plate 2 b and the plate 2 c serving as the back wall of the case 2 A gap slightly larger than the thickness dimension of the regular coin A is formed. The upper end of the case 2 has a shape that prevents the insertion of a fake coin having a diameter dimension larger than that of the regular coin A and a fake coin having a thickness dimension larger than that of the regular coin A between the plates 2b and 2c. The coin slot and other places are formed. That is, the dimension in the longitudinal direction of the opening in the place other than the coin insertion slot of the embodiment is slightly larger than the diameter dimension of the regular coin A, and the dimension in the fore edge direction is set slightly larger than the thickness dimension of the regular coin A. Has been. In addition, it is preferable that the case 2 can be divided into the case main body 2a and the plate 2b by removing the shaft 3 and screws. This is to facilitate maintenance. Moreover, it is preferable that at least the plate 2b of the case main body 2a and the plate 2b is made of transparent plastic. This is to prevent troubles by making the inside visible through the transparent part.

  On the inner surface of the plate 2c, two ribs 5 extending obliquely downward from other places of the coin insertion slot are formed apart from each other. The two ribs 5, the plate 2b, and the plate 2c define a coin passage 6 that constitutes a coin introduction path together with the coin insertion slot and other places. The interval between the two ribs 5 becomes narrower as it goes downward, and is set to be slightly larger than the diameter dimension of the regular coin A at the lower end.

  In the case of the embodiment, since the shape of the coin insertion slot and other places is such as to prevent the insertion of a fake coin having a diameter larger than that of the regular coin A, the coin passage 6 has a regular coin. There is no case where a fake coin having a diameter larger than A is entered. However, it is possible to introduce a fake coin having a diameter larger than that of the regular coin A into a coin insertion slot or the like, and prevent further introduction of the fake coin in the coin passage 6. Of course, it is also good.

  Further, as shown in FIG. 2, one end of the operation lever 7 is rotatably supported on the plate 2c by the shaft 8 so as to be operated along the outer surface of the plate 2c. Yes. The operation lever 7 is urged upward by a torsion coil spring 9 wound around the shaft 8. A magnet 11 is disposed in the middle of the operation lever 7. The magnet 11 normally faces the position in the coin passage from the long hole 11 formed in the plate 2c. When the operation lever 7 is operated downward, the magnet 11 operates integrally with the operation lever 7 and moves along the long hole 10 to take a position outside the coin path. Further, the other end (free end) of the operation lever 7 is formed with a protrusion 12 that protrudes inward of the case main body 2a. The protrusion 12 protrudes into the case 2 from a long hole 13 formed in the plate 2c.

  On the other hand, a half-moon pendulum 14 is provided on the inner surface of the plate 2b. Specifically, the center portion of the pendulum 14 is rotatably supported by the shaft 15. The diameter of the pendulum 14 is about twice the diameter of the regular coin A. And the pendulum 14 is installed so that the half part may be located in the place which extended the coin channel | path 6 below as shown in FIG. The pendulum 14 has two protrusions 16 formed on the surface on the plate 2c side. The two protrusions 16 have the same curvature as that of the regular coin A, and can capture the regular coin A by supporting two points on the outer periphery of the regular coin A. The two protrusions 16 constitute a coin receiver. The two protrusions 16 are positioned substantially on the extension line of the two ribs 5 when the pendulum 14 is in an initial state (a state where no coin is inserted). Of the two protrusions, one protrusion 16 located near the outer periphery of the pendulum 14 causes the coin to flow to the regular coin discharge path 18 described later when the pendulum 14 does not rotate or is insufficiently rotated. It works to inhibit. The two protrusions 16 function to rotate the pendulum 14 in one direction by the weight of the regular coin A when the regular coin A is captured. On the other hand, the two protrusions 16 function to pass between the two protrusions 16 in the case of a pseudo coin having a diameter smaller than that of the regular coin A. The pendulum 14 can be detached from the plate 2b by removing the shaft 15.

For this reason, the swing range of the pendulum 14 is restricted. That is, in the case of the regular coin A, the pendulum 14 is rotated by a predetermined angle in one direction by the regular coin A to drop the coin A below the coin passage 6, while the diameter dimension is smaller than that of the regular coin A. In the case of a fake coin, the initial state of the pendulum 14 is set so that the two coins 16 can be passed through and the fake coin can be dropped below the pendulum 14. The initial state in this case is a state that the pendulum 14 can take when no coin is inserted. In the case of the embodiment, since the coin passage 6 is inclined, the lower half of the half-moon pendulum 14 is restricted so as to close the lower end opening of the coin passage 6. On the other hand, in the case of the regular coin A, the pendulum 14 according to the embodiment is a state in which the pendulum 14 can be rotated by a predetermined angle in one direction by the weight of the regular coin A and the coin A can be dropped below the coin path 6. It is designed to rotate from the initial state. In order to achieve the above configuration, in the case of the embodiment, the long hole 30 into which each of the protrusion 16 provided on the plate 2c side of the pendulum 14 or the protrusion 14a provided on the opposite surface of the pendulum 14 enters, 31 length dimensions and shapes are set.
Further, the installation portion of the pendulum 14 in the plate 2b is configured such that the inner surface side is a concave portion and the outer surface side (front surface side) is a convex portion. The pendulum 14 is installed in a recess on the inner surface side of the plate 2b, and is configured such that only two protrusions 16 protrude into the coin passage 6. Further, the pendulum 14 can be rotated in a recess on the inner surface side of the plate 2b.

  Further, as shown in FIG. 4, a cam 17 is formed on the inner surface of the plate 2 b at a portion opposite to the shaft 8, that is, a portion facing the protrusion 12 of the operation lever 7. When the operation lever 7 is operated downward, the cam surface 17a of the cam 17 protrudes inwardly downward so that the projection 2 separates the plate 2b from the plate 2c. It has a shape. When the plate 2b is moved away from the plate 2c, one of the two protrusions 16 near the outer periphery of the pendulum 16 will be described later if the pendulum 14 does not rotate or is insufficiently rotated. The coin is circulated to the normal coin discharge path 18 side, and a gap larger than the thickness dimension of the normal coin A is formed between the other protrusion 16 and the plate 2c. ing.

  Further, in the coin sorting device 1, a regular coin discharge path 18 and a fake coin discharge path 19 are formed below the pendulum 14 in the case 2. The regular coin discharge path 18 is located below the portion where the protrusion 16 of the pendulum 14 is formed, and the false coin discharge path 19 is located below the extending direction of the coin path 6. The regular coin A is configured to be discharged to the regular coin discharge path 18, and the false coin having a diameter smaller than that of the regular coin is discharged to the false coin discharge path 19. In order to facilitate the distribution between the regular coin and the fake coin, an inverted V-shaped distribution member 32 is provided.

The coin sorting device 1 configured as described above operates as follows.
When a regular coin A, that is, a coin having a predetermined diameter and weight is inserted into the coin passage 6, the coin is blocked from passing by the two protrusions 16 as shown in FIG. 14 rotates against the urging force as indicated by a two-dot chain line. Then, the coin A is dropped into the regular coin discharge path 18. At this position, the one protrusion 16 existing near the outer periphery of the pendulum does not hinder the circulation of coins toward the regular coin discharge path 18 side.
Further, when trying to insert a fake coin B having a diameter larger than the diameter dimension of the regular coin A into the coin path 6, the width of the coin insertion slot 6a of the coin path 6 is slightly larger than the diameter dimension of the regular coin A, Since the gap in the thickness direction is only slightly larger than the thickness of the regular coin A, the fake coin B is inserted into the coin path 6a of the coin path 6 as shown in FIG. 6 is blocked from entering.
Further, when a false coin C smaller than the diameter size of the regular coin A is inserted into the coin passage 6, as shown in FIG. 7, the false coin C passes between the protrusions 16 as shown by a two-dot chain line. Then, it falls into the fake coin discharge path 19.
Further, when a false coin D having the same diameter as the regular coin A and having a small weight is inserted into the coin passage 6, the false coin D is prevented from passing by the protrusion 16, as shown in FIG. In this case, the pendulum 14 does not rotate at all or does not rotate due to the weight of the false coin A. Incidentally, in the case of a coin having a smaller weight and smaller diameter than the regular coin A, the passage is not blocked by the protrusion 16, and it passes as it is and falls to the false coin discharge path 19.
Further, when a false coin E, which is a magnetic material, is inserted into the coin passage 6, the false coin E is attracted by the magnet 11 as shown in FIG.

Next, how to process the fake coin D held by the pendulum 14 and the fake coin E attracted by the magnet 11 will be described.
In this case, by operating the operation lever 7, it is discharged to the false coin discharge path 19.
That is, when the operation lever 7 is operated, the plate 2b is pushed open through the projection 12 of the operation lever and the cam surface 17a of the plate 2b, and the coin passage 6 is opened. At this time, the gap between the tip of one protrusion 16 (protrusion 16 near the outer periphery of the pendulum 14) and the plate 2c is smaller than the thickness dimension of the false coin, and the gap between the tip of the other protrusion 16 and the plate 2c. Is larger than the thickness dimension of the false coin, so that the false coin is not discharged to the regular coin discharge path 18 by being obstructed by the one protrusion 16, and a gap between the tip of the other protrusion 16 and the plate 2c is formed. It is dropped and discharged to the fake coin discharge path 19.
In the case of the false coin D which is a magnetic body, the magnet 11 comes off the coin path 6 as indicated by a two-dot chain line in FIG. Is released from the attractive force of the magnet 11, and is dropped and discharged to the false coin discharge path 19.

  As mentioned above, although embodiment of this invention was described, it cannot be overemphasized that this invention is not limited to this embodiment, A various deformation | transformation is possible in the range which does not deviate from the summary.

  For example, a gap smaller than the thickness of the normal coin A is formed between the tip of the protrusion 16 different from the protrusion (inner protrusion) 16 near the outer periphery of the pendulum 14 and the plate 2c, so that it is thicker than the normal coin A. The false coin having a small size may be guided to the false coin discharge path 19 through the gap between the tip of the inner protrusion 16 and the plate 2c without the operation lever 7 being operated.

  Needless to say, the coin sorting device of the present invention can be used not only for sorting coins but also for sorting game coins and the like.

  In the embodiment, the plate 2b is configured to rotate about the shaft 3 with respect to the plate 2c. However, the opposed surfaces of the plate 2c and the plate 2b are kept close to each other while approaching and separating (contacting / separating). It may be configured as follows.
