BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a coin payout device capable of reliably guiding coins into a coin receiving hole in a rotor and improving coin payout efficiency.

[0002]

2. Description of the Related Art For example, in a gaming machine such as a money changing machine, a vending machine, and a slot machine, a coin payout device is used to collect coins such as coins and medals and to pay out a necessary number of coins. Is used.

Further, in such a coin payout device, conventionally, as shown in FIGS. 9 and 10, for example, a rotor for taking out a large number of coins C stored in a hopper A one by one from a coin payout exit B. D is used. This rotor D
Has a disk shape rotatably supported in a circular recess E provided in a motor mounting board, and a plurality of coin receiving holes G are vertically formed around the center of rotation thereof. Moreover, a guide path H for discharging the lowest coin C0 out of the coins accommodated in the coin receiving hole G to the outside from the outer peripheral surface is recessed on the lower surface thereof.

Therefore, when the rotor rotates, the coin payout opening B and the guide path H provided on the inner peripheral wall surface of the circular recess E are provided.
Each time, and coins are matched, the coins C stored in the coin receiving hole G from the hopper A are discharged one by one from the coin payout exit B, and the number of coins and the payout are accurately performed.

[0005]

However, the rotor D of such a payout device is conventionally formed in a disk shape having its upper and lower surfaces substantially flat, and the coin receiving hole G is formed so as to substantially coincide with the outer circumference of the coin. ing. Therefore, various postures
The coins in the hopper that are accommodated in an overlapping manner at an angle are difficult to be guided into the coin receiving hole G, and sometimes coins are not inserted into the receiving hole G, so that the rotor is rotated in an empty state and coins are struck, and the coins are paid out. It had reduced efficiency.

The present invention is based on the fact that a raised body having a guide surface inclined downward toward the coin receiving hole is provided on the upper surface of the rotor, so that the coin in the hopper can be smoothly guided into the receiving hole. It is an object of the present invention to provide a coin payout device that can solve the above problem.

[0007]

In order to achieve the above object, a coin payout device of the present invention is a substrate provided with a circular recess on the bottom of a hopper into which coins are inserted,
A disc-shaped rotor that rotates in the circular recess, and a coin receiving hole that allows the bottom coin to slide on the bottom surface of the circular recess by accommodating the coin in the rotor and penetrating vertically A coin payout device provided in parallel in the circumferential direction, wherein the substrate is provided with a passage through which an inlet provided on the inner peripheral wall surface of the circular recess is connected to an outlet on the outer periphery of the substrate and through which the lowest coin can pass. On the upper surface of the rotor, there is provided a raised body having a guide surface that is inclined downward from the top of the rotor extending radially outward from the center of rotation of the rotor toward the coin receiving hole.

[0008]

As described above, the raised body on the upper surface of the rotor has the top portion that extends radially outward through the coin receiving holes. Thus, the coins on the bottom of the hopper are distributed in fan-shaped areas on the rotor that are bounded by the tops. Further, since the raised body has the guide surface inclined downward from the top toward the coin receiving hole, the dispersed coins can be surely guided downward and inserted into the coin receiving hole. In addition, the apex increases the flow of coins in the hopper, such as enhancing agitation, and increases the chances of inserting coins into the receiving holes. As a result, blank coins can be prevented from being dispensed and the payout efficiency can be greatly improved.

[0009]

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. 1 to 3, the coin payout device 1 is a coin C
A rotator 16 is provided on the upper surface of the rotor 6 while having a substrate 3 arranged at the bottom of the hopper 2 into which is charged and a disc-shaped rotor 6 rotating in a circular recess 5 of the substrate 3. ing.

In this example, the substrate 3 is formed of a frame plate 7 for mounting the motor M with a speed reducer for driving the rotor, and a rotor receiver 9 integrally fixed to the upper surface thereof. The rotor receiver 9 is a frame. The bottom piece 9A along the plate 7 has a bottomed cap shape in which a cylindrical flange 9B is raised, and the circular recess 5 for holding the rotor is formed by the recessed recess surrounded by the flange 9B and the bottom piece 9A. .

Further, the hopper 2 is attached to the flange 9B of the rotor receiver 9, and the hopper 2 is provided at the lower end of a container-shaped main portion 2A for receiving and accommodating a large number of inserted coins C. A cylindrical bottom portion 2B is provided which is connected to the circular recess 5 by fitting with the upper end of the flange 9B. In addition, at the lower end of the bottom portion 2B, there is a fitting groove portion 2B1 that fits with a locking portion 9B1 provided at the upper end of the flange 9B,
Further, the inner peripheral wall surface 2S at the lower end of the bottom portion 2B prevents the rotor 6 from coming off due to a step K between the inner wall surface S1 of the circular concave portion 5 and the inner peripheral wall surface S1 which is radially inward.

Further, the rotor receiver 9 has a passage 10 for passing coins which extends from an inlet 10A provided on the circumferential wall surface S1 of the circular recess 5 to an outlet 10B on the outer periphery of the substrate 3. The bottom piece 9A is formed on the upper surface of the extending portion 9A1 extending radially outward from the flange 9B. The inlet 10A is formed by a notched portion having a width and a height that allows one coin C to pass through a part of the lower end of the flange 9B, and the notch is provided before and after the inlet 10A. By disposing a pair of guide plates 11 and 11 having substantially the same height as the portion, the passage 1 is provided between the guide plates 11 and 11.
0, and the passage 10 has the extension 9A.
An outlet 10B is provided at the outer periphery of the substrate by opening at the outer end of 1. An upper plate (not shown) is bridged between the guide plates 11 to cover the upper surface of the passage 10 to prevent the coin C from falling during passage.

An electric motor M with a speed reducer is fixed to the lower surface of the frame plate 7 via a collar 12 or the like, and its output shaft M
The upper end of 1 is inserted through a central hole 3A provided in the substrate 3,
It projects into the circular recess 5 and concentrically with the circular recess 5.

A rotor 6 which rotates concentrically within the circular recess 5 is attached to the upper end of the output shaft M1. The rotor 6 has a larger diameter than the inner peripheral wall surface 2S of the hopper 2 and has a disc shape interposed between the step K and the bottom surface S2 of the circular recess 5, and a raised body 16 is provided on the upper surface thereof. It is provided.

In this example, the rotor 6 includes a reinforcing metal layer made of a rigid body such as a metal plate, and a lower synthetic resin layer made of a synthetic resin material or the like for reducing friction with the bottom surface S2. A two-layer structure of the above, and the synthetic resin layer is preferably
It is formed of a bearing material having a low coefficient of friction and is detachably attached to the metal layer so that it can be replaced when worn.

A plurality of, in the present example, five coin receiving holes 17 penetrating vertically are arranged in the rotor 6 side by side at an equal angular pitch in the circumferential direction around the center of rotation of each rotor. By penetrating the rotor 6 in the vertical direction, 17 receives coins C from the hopper 2 from the opening above them and stores them in an overlapping manner inside, and at the same time, puts the bottom coin C0 exposed from the lower opening in the rotor 6. With rotation, it can slide on the bottom surface S2 of the circular recess 5.

As shown in FIG. 4, the rotor 6 has a guide path 19 for guiding the sliding lowermost coin C0 to the outside in the radial direction on the lower surface thereof, and the coin centering around the rotation center of the rotor. A circular groove 20 connecting the receiving holes 17 and extending in the circumferential direction is provided. In FIG. 4, a check pattern is provided on the guide path 19 and a dot pattern is provided on the circular groove 20 for the sake of convenience.

As shown in FIG. 4, the guide path 19 is a concave guide groove extending from the opening under each coin receiving hole 17 to the outer peripheral surface of the rotor 6, and has a width and a coin exceeding the diameter of the coin C. By having a depth substantially exceeding the thickness of C, the lowermost coin C0 is guided radially outward from the lower opening through the guide path 19 by the centrifugal force of the rotor rotation. In this example, the side edge e1 on the rear side in the rotation direction among the side edges sandwiching the guide path 19 is a tangent line L from the rotation center O to the coin receiving hole 17 and a contact point P between the coin receiving hole 17.
It is formed by a circular arc that is curved outward in the radial direction and rearward in the rotational direction from a position P1 in the vicinity of the convex position.

Therefore, when the rotor rotates, the coin C0 in the guide path 19 pushed by the side edge e1 is moved to the side edge e.
Since the 1 forms the circular arc, it is urged outward in the radial direction by a stronger force, and every time the guide path 19 and the entrance 10A coincide with each other, the coin C0 goes through the entrance 10A and exit 10.
It can be released out of B.

In the passage 10, a sensor 22 for detecting passage of coins C0 is attached, and a stopper 23 for stopping the rotation of the output shaft of the electric motor M with a speed reducer is provided after detecting the required number of coins. To be

The sensor 22 is a non-contact type sensor in this example, and an optical sensor of a light transmission type or a light reflection type is preferably used.

In this embodiment, the stopper 23 engages with a cam 24 fixed to the lower end of the output shaft of the electric motor M with a speed reducer and a locking piece 24A of the cam 24 to engage with the output shaft, as shown in FIG. Locking lever 25 that prevents the rotation of the
5 and a release lever 26 for releasing the engagement with the locking piece 24A and permitting the rotation of the output shaft.

The circular groove 20 is an escape groove provided in the circular recess 5 for avoiding a collision with a posture maintaining body 8 which will be described later, and is concentric with the rotor 6, that is, centered around the rotation center of the rotor 6. The coin receiving hole 17 is connected to form a donut shape extending in an arc, and the circular groove 20 is formed at the position P.
1 and the coin receiving hole 17 at a position radially inward of the position P1 and intersecting with the coin receiving hole 17.
The passage of the coin C into the circular groove 20 is prevented while maintaining the radial biasing effect on the coin C0.

The raised body 16 has a top portion 30 extending radially outward from the rotation center portion Q of the rotor 6 through the space between the coin receiving holes 17 and 17, and between the top portions 30 and 30. Forms a guide surface 31 that is inclined downward from each top 30 toward the coin receiving hole 17.

Therefore, the coin C inserted into the hopper 2
Is dispersed in the fan-shaped area on the rotor 6 defined by the top portion 30, and the dispersed coins C are
The coin receiving hole 1 is guided downward along the guide surface 31.
It is surely inserted in 7.

In the present example, the apex portion 30 forms the apex R which is most raised on the center of rotation and is curved in a concave arc outward from the apex P in the radial direction.
The guide surfaces 31 adjacent to each other intersect at an acute angle at the top 30. By providing the vertices and forming the apex 30 at an acute angle in this manner, the dispersion effect in the fan-shaped region is enhanced. Further, by making the top 30 into a concave arc and making the height thereof different in the radial direction, the stirring effect at the time of rotation is enhanced and the fluidity of the coin is improved.

If the coin C does not stay on the top 30, the top 16 may be formed in a convex arc and a straight line outward in the radial direction, or adjacent guide surfaces. Besides connecting 31 and 31 with a smooth circular arc at the top 30, the rotation center portion Q may be formed with a spherical surface or the like.

The bottom surface S2 of the circular recess 5 of the rotor receiver 9
Further, a posture maintaining body 8 facing the entrance 10A and extending in the circumferential direction within the rotational movement trace Y of the coin receiving hole 17 is arranged. In other words, the rotation trace Y is a donut-shaped region on the bottom surface S2 through which the coin receiving hole 17 passes as the rotor 6 rotates, as shown in FIG.

The posture maintaining body 8 is formed of, for example, a metal wire rod which is elastically deformable, and in this example, as shown in FIGS. 3 and 8, it is fixed to the frame plate 7 via a screw fitting 32 or the like, for example, U. A leg piece portion 8B which rises above the bottom surface S2 from the fixed portion 8A of the character is provided, and the leg piece portion 8B is provided.
At the upper end, a substantially horizontal body portion 8C extending in the circumferential direction in the rotation trace Y toward the downstream side of the rotation is provided. In the present example, the entire length of the body portion 8C is interposed in the rotational movement trace Y, and the height from the bottom surface S2 is substantially equal to the thickness of the coin C, and is preferably set to be slightly smaller than the thickness. At the same time, in this example, a folding-back portion 8D is provided at the tip of the body portion 8C to prevent the coin C from being inserted between the body portion 8C and the bottom surface S2 by being folded back in a U shape.

The bottom piece 9A of the rotor receiver 9 is provided with a cutout hole portion 33 for accommodating and disposing the posture maintaining body 8 and allowing the tip of the body portion 8C to sink below the bottom surface S2. Set up.

Therefore, as shown in FIG. 6, the posture maintaining body 8 is arranged so that the body portion 8C faces the entrance 10A and is arranged in the rotational movement trace Y, so that it is discharged from the coin receiving hole 17 to the passage 10. In cooperation with the coin C0 during
The next upper coin C1 is supported substantially horizontally, and as shown in FIG. 7, it is possible to prevent an inclination of the upper coin C1 on the counter-rotation side, that is, the rotation upstream side.

Even after the coin C0 is completely discharged, while the coin C1 on the coin C1 completely passes over the posture maintaining body 8, the posture maintaining body 8 is moved upward as shown in FIG. Since the coin C1 is supported with the upstream side of rotation facing upward, it is possible to prevent the coin from being caught between the rotor 6 and the bottom surface S2. Further, when an external force is applied from above, the tip of the body portion 8C can elastically sink downward from the bottom surface S2, so that the posture maintaining body 8 can be prevented from being deformed and damaged, and the bottom coin C0 can be smoothed. Enables smooth sliding.

[0033]

As described above, in the coin payout device of the present invention, since the upper surface of the rotor is provided with the raised body having the guide surface inclined downward toward the coin receiving hole, the coin receiving hole is surely inserted into the coin receiving hole. Therefore, it is possible to prevent blank hitting and greatly improve the coin payout efficiency.
