Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a coin payout device capable of preventing coins from being bitten inside the device and capable of paying out coins reliably.

[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, in such a coin payout device, two to three coins C are housed in the coin receiving hole G of the rotor D in multiple stages, and therefore, as shown in FIGS. Thus, in the middle of discharging the lowest coin C0 to the payout opening B, the coin C1 above it
Will be partially overlapped and inclined. As a result, when the inclined lower edge e accidentally faces the upstream side in the rotation direction due to the action of external force, vibration, etc., that is, when the coin is inclined with the counter rotation side facing down, the rotor D and the lower surface of the circular recess E are The coin C1 is bitten in between, causing the rotation of the rotor D to be locked and causing a failure or the like.

The present invention is based on the fact that a posture maintaining body extending in the circumferential direction within the rotational movement trace of the coin receiving hole is arranged on the bottom surface of the circular recess, and the coin is caught between the rotor and the substrate. It is an object of the present invention to provide a coin payout device that can be prevented and can solve the above problems.

[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 lowermost coin to slide on the bottom surface of the circular recess by accommodating the coin in the rotor and penetrating it vertically What is claimed is: 1. A coin payout device, which is arranged side by side in a circumferential direction, wherein the substrate is provided with a passage through which an inlet provided on an inner peripheral wall surface of the circular recess is connected to an outlet on an outer periphery of the substrate and through which the lowest coin can pass. A guide groove for guiding the lowermost coin outward in the radial direction as the rotor rotates, and a circular groove that connects the coin receiving hole around the rotation center of the rotor and does not allow the lowermost coin to pass. And a coin formed between the coin receiving hole and the bottom surface of the circular concave portion of the substrate, which extends in the circumferential direction in the rotational movement trace of the coin receiving hole facing the inlet and is discharged from the coin receiving hole into the passage. That work are arranged position maintaining member capable of elastic deformation preventing inclination to lower the anti-rotation side of the coin on the next.

[0008]

In the bottom of the circular recess in which the coin slides in this way, the posture maintaining body extending in the circumferential direction within the rotational movement trace of the coin receiving hole is arranged facing the entrance of the passage.

The posture maintaining member cooperates with the coins while it is discharged from the coin receiving hole into the passage, and supports the lower surface of the upper coin, which overlaps the discharged coins, for example, in a substantially horizontal direction to prevent the inclination. To do. Further, after that, when the discharged coins are completely discharged into the passage and the upper coin is supported only by the posture maintaining body, since the posture maintaining body extends in the circumferential direction, at least the side edge on the rotating side of the coin is half. It contacts the bottom surface before the side edge on the rotation side. Therefore, it is possible to prevent the tilt of the upper coin with the counter-rotation side facing down even after the completion of discharging the coin. As a result, accidental biting of the coin between the rotor and the substrate can be reliably suppressed even when an external force, vibration, or the like is applied.

[0010]

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
It is provided with a substrate 3 arranged on 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.

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, and 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 concave 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 storing 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 leads 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. This passage 10 is, in this example, 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 reducer is fixed to the lower surface of the frame plate 7 via a collar 12 and 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 diameter larger than that of the inner peripheral wall surface 2S of the hopper 2, and is disposed between the step K and the bottom surface S2 of the circular recess 5 and has a disc-shaped main body portion 15, and is integrally formed on the upper surface thereof. And a ridge 16 to be fixed.

In this example, the main body 15 is made of a rigid metal body such as a metal plate for reinforcement, and a synthetic resin material or the like, which is a lower synthetic resin layer for reducing friction between the bottom surface S2. And the synthetic resin layer is preferably formed of a bearing material having a low coefficient of friction and is detachably attached to the metal layer so as to be replaced when worn.

Further, the main body 15 has a plurality of, in the present example, five coin receiving holes 17 penetrating vertically, arranged in parallel in a circumferential direction around the rotation center of the rotor 6 at an equal angular pitch. The coin receiving hole 17 vertically penetrates the main body portion 15 to receive the coin C from the hopper 2 from the opening above it and store the coins in an overlapping manner, and at the same time, to expose the lowermost coin C0 from the lower opening. Can be slid on the bottom surface S2 of the circular recess 5 as the rotor 6 rotates.

As shown in FIG. 4, a guide path 19 for guiding the sliding lowermost coin C0 to the outside in the radial direction is formed on the lower surface of the main body portion 15, and the center of the rotor is the rotation center of the rotor. A circular groove 20 is provided which connects the coin receiving holes 17 and extends in the circumferential direction. 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 exceeding the diameter of the coin C and a coin. 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.

A sensor 22 for detecting the passage of coins C0 is mounted in the passage 10, 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 a light transmission type or a light reflection type optical sensor is preferably used.

In this embodiment, the stopper 23 is engaged 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 the output shaft. 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 of the rotor 6 is
Has a top 30 extending radially outward from the rotation center portion Q of the coin receiving hole 17 between the coin receiving holes 17 and 17, and between the tops 30 and 30 from the top 30 to the coin receiving hole 17. A guide surface 31 that slopes downward is formed.

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 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 property when the rotor 6 rotates is increased and the fluidity of the coin is increased.

In the raised body 16, if the coin C does not stay on the top 30, the top 30 may be formed as 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.

Further, in the present application, the attitude maintaining body 8 that extends in the circumferential direction within the rotational movement trace Y of the coin receiving hole 17 is disposed on the bottom surface S2 of the circular recess 5 of the rotor receiving 9 facing the inlet 10A. It should be noted that the rotation trace Y is, in other words, as shown in FIG. 6, as the rotor 6 rotates, the coin receiving hole 1
It is a donut-shaped region on the bottom surface S2 through which 7 passes.

The posture maintaining member 8 is formed of, for example, a metal wire rod that can be elastically deformed, and in this embodiment, 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 has a cutout hole portion 33 for accommodating and arranging 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 such that the body portion 8C faces the entrance 10A and is disposed in the rotational movement trace Y, so that the coin is received from the coin receiving hole 17 into 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 C0 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.

[0034]

As described above, according to the coin payout device of the present invention, in the bottom of the circular concave portion and within the rotational movement trace of the coin receiving hole,
Since the posture maintaining body 8 extending in the circumferential direction is arranged, it is possible to prevent the coin from being caught between the rotor and the substrate, ensure the coin payout operation, and suppress the occurrence of a failure or the like.
