Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a coin sending device capable of continuously sending coins that are flat circular plates.

[0002]

2. Description of the Related Art There is known a coin delivery apparatus for continuously delivering coin-shaped members (hereinafter referred to as coins), which are flat circular plates, such as coins used in currency exchange machines, medals and tokens used in game machines and the like. ing. For example, Tokuho 6
This is the device described in Japanese Patent No. 44305/44. According to such an apparatus, a bucket or hopper for accommodating a plurality of coins and a plurality of coin holes for passing the coin in the thickness direction are provided so as to close the bottom hole of the hopper. A coin driving member that is rotatably driven to send out the coin that has passed through the coin hole to the outer peripheral side, and the coin accommodated in the hopper is passed through the coin hole while being stirred while being continuously transmitted. Is done.

According to the conventional coin delivery device, a plurality of agitating projections are formed on the inner wall surface of the hopper, and a large amount of coins in the hopper are agitated while being stably inserted into the coin hole of the coin driving member. When the number of coins in the hopper decreases, the coins stuck or leaning on the inner wall surface of the hopper are returned to a posture that is easy to fit into the coin hole of the coin driving member, that is, a substantially horizontal posture. As a result, the coin sending efficiency is improved.

[0004]

However, according to the above-mentioned conventional coin feeding device, the structure of the hopper must be complicated in order to provide the stirring projection while maintaining the required rigidity. There was a disadvantage that the price was high. For example, since a large amount of coins in a hopper rotated by a coin rotation driving member are impacted by a stirring protrusion for stirring and stirring the coin, the hopper provided with the stirring protrusion is provided. The rigidity of the coin is required to be relatively large, and the provision of the agitating projections also requires a relatively large drive torque for the coin rotation drive member. Since the capacity of the motor and the speed reducer for driving the rotary drive member and the rigidity of the coin rotary drive member are also increased, there is a disadvantage that the apparatus becomes large and expensive.

The present invention has been made in view of the above circumstances, and an object of the present invention is to reduce the rigidity of a hopper, a coin rotating drive member, etc., and to manufacture a coin at a low cost. To provide a sending device.

[0006]

SUMMARY OF THE INVENTION In order to achieve the above object, the gist of the present invention is to provide a hopper for accommodating a plurality of coins and a plurality of coin holes for passing the coins in the thickness direction. A coin drive member that is provided so as to close the bottom hole of the hopper, and is rotationally driven to send out the coin that has passed through the coin hole to the outer peripheral side,
In a coin feeding device for continuously feeding coins contained in the hopper while passing through the coin holes while stirring the coins, a coin flowing in the hopper near the bottom hole on the inner peripheral surface of the hopper. Is provided with a stirring projection for stirring the mixture.

[0007]

According to this structure, since the stirring protrusion for stirring the coin flowing in the hopper is provided near the bottom hole on the inner peripheral surface of the hopper,
Since the stirring protrusion is provided at a portion where the coins easily accumulate in the hopper, a high stirring efficiency is obtained. Therefore, even if the stirring protrusion is relatively small, the coin is sufficiently stirred, and an inexpensive hopper with low rigidity is used. be able to.

[0008]

Here, preferably, the bottom hole of the hopper and the coin rotation driving member closing the bottom hole are inclined, and the stirring projection is formed at a peripheral portion of the inclined bottom hole. It is provided in the lower region. With this configuration, the stirring protrusion is provided at a portion where the coins easily accumulate in the hopper, and high stirring efficiency can be obtained. Therefore, even if the stirring protrusion is relatively small, the coin is sufficiently stirred, and the rigidity is further increased. And an inexpensive hopper with a low cost.

Preferably, the stirring protrusion is a longitudinal protrusion in a direction intersecting the flowing direction of the coin which is caused to flow in the rotation direction of the coin rotation driving member in the hopper. By doing so, a relatively high stirring efficiency can be obtained for the coin, so that the coin is sufficiently stirred even if the stirring protrusion is relatively small, and an inexpensive hopper with lower rigidity can be used.

[0010] Preferably, a chamfer is provided at an outer peripheral edge of the hopper side opening of the coin hole. With this configuration, since the rotational torque of the coin rotation drive member can be reduced, the rigidity of the coin rotation drive member, the speed reducer and the motor for driving the same can be reduced, and the coin delivery device can be configured at a lower cost. .

[0011]

As shown in FIGS. 2 and 3, the guide member 14 is for guiding the coin 32 which is a circular plate-shaped metal member housed in the hopper 16 and has three shallow concentric steps. A first hole 34 having a relatively small diameter, a second hole 36 having an intermediate diameter, and a third hole 38 having a large diameter are formed on the upper surface thereof. The bottom surface 40 of the first hole 34 functions as a guide plane that slides on one surface of the coin 32 to be guided, and the inner peripheral surface 42 of the first hole 34 functions as a guide inner peripheral surface that guides the coin 32 in the circumferential direction. ing. In the upper position of the side of the inclined guide member 14, the first hole 34, the second hole 36, and the third
A part of the inner peripheral surface of the hole 38 is cut out,
A delivery groove 44 having a groove bottom flush with zero is formed in the lateral direction of the inclined guide member 14, that is, in the horizontal direction.

As shown in FIG. 2, a fixed roller 46 and a movable roller 48 are erected on the guide member 14 in a direction perpendicular thereto. The fixed roller 46 is provided in the delivery groove 44 such that the center of rotation is located on the outer peripheral side of an extension of the inner peripheral surface 42 and the outer peripheral surface is located on the extension of the extension. The fixed roller 46 prevents the abrasion caused by friction between the coin 32 and the guide member 1.
4 to improve the durability, and corresponds to the guide inner peripheral surface end portion of the inner peripheral surface 42 functioning as the guide inner peripheral surface of the coin 32. Further, the movable roller 48 is located on the inner peripheral side with respect to the movement locus of the outer peripheral position of the coin 32, that is, the extension of the inner peripheral surface 42 in the radial direction of the inner peripheral surface 42, that is, the radial direction of the coin driving member 52. The guide member 14 is provided so as to be movable toward and away from the fixed roller 46, and is urged to approach the fixed roller 46. That is, the bottom surface 4 of the guide member 14
In the vicinity of the feed groove 44, a long hole 50 in the circumferential direction is provided to allow the movable roller 48 to move. The movable roller 48 standing up through the long hole 50 is moved by a spring (not shown) in FIG. Is urged to the lower left.

The coin driving member 52 is a disk-shaped member for driving the coins 32 in the hopper 16 one by one, and is an electric motor 54 and a speed reducer 56 to which the base frame 12 is fixed. As a result, it is driven to rotate continuously in the direction of the arrow in FIG. The coin driving member 52 is connected to an output shaft 58 of a speed reducer 56, and is rotationally driven around an axis located at the center of curvature of the inner peripheral surface 42 and perpendicular to the bottom surface 40. The coin driving member 52 is rotatably accommodated in the second hole 36 of the guide member 14, and the lower end of the hopper 16 is fitted into the third hole 38 of the guide member 14 so that the base frame is 12
, The movable roller 48 erected through the elongated hole 50 and the coin driving member 5
2 underneath and covered by it,
The coin driving member 52 is disposed so as to close the bottom hole 60 of the hopper 16 in an inclined state.

The coin driving member 52 has a conical raised portion 61 protruding upward from the inner peripheral portion of the upper surface in the direction of the rotation axis, that is, a plurality of coin driving members 52 (eight in this embodiment) for passing the coin 32 in the thickness direction. ) To drive the coin 32 passing through the coin hole 62 and the coin 32 so as to abut the coin 32 and urge the coin 32 in the circumferential direction and the direction toward the outer periphery. A plurality (eight in the present embodiment) of drive projections 66 are formed on the lower surface with a contact surface 64 inclined toward the anti-rotational direction as it goes.

The coin hole 62 has a diameter larger than the diameter of the coin 32 by a predetermined value, and is formed through the coin driving member 52 in the thickness direction. A coin driving member 5 is provided on the entire outer periphery.
2 is formed with a chamfered upper surface 68 for reducing the rotational driving torque and allowing the coin 32 in the hopper 16 to fit more smoothly into the coin hole 62. The top chamfered portion 68 is formed of four regions divided by a radial line of the coin driving member 52 passing through the center of the coin hole 62 and a circumferential line of the coin driving member 52 passing through the center of the coin hole 62. The region located on the downstream side in the rotation direction and on the outer peripheral side of the coin driving member 52 is formed wider than other regions.

The coin hole 62 has an inner peripheral edge (inner peripheral surface) which protrudes from a downstream portion of the coin drive member 52 in the rotational direction to an upstream portion, and a protruding portion 70 of the coin hole 62. A lower surface chamfered portion 72 formed on the inner peripheral edge and on the lower surface side of the portion opposite to the overhang portion 70, that is, on the guide member 14 side is formed. The overhang portion 70 is located at a higher position than the height at which a plurality of (two in this embodiment) coins 32 received by the guide member 14 are stacked on the lower surface side of the coin driving member 52 in the coin hole 62. Is formed. Further, as shown in FIG. 2, the overhang portion 70 is formed in a crescent shape in plan view from the direction of the rotation axis. The center position of the crescent-shaped overhanging portion 70 is the coin driving member 52 passing through the center of the coin hole 62.
Of the four areas divided by the radial line of the coin drive member 52 and the circumferential line of the coin drive member 52 passing through the center of the coin hole 62, the area located on the downstream side in the rotation direction and on the inner circumference side of the coin drive member 52 Is provided.

As described above, the overhang portion 70 is

It is easy to drop. For example, if the overhang 70 is as high as one coin 32, one end of the coin 32 is placed on the overhang 70 and dropped in an inclined state even at the initial stage of coin insertion. However, the probability of the coin 32 being dropped by the smaller inclination is reduced, and the coin 32 may not be smoothly discharged from the coin hole 62 at the initial stage of coin insertion. However, as in the present embodiment, when the overhang portion 70 is at least two coins in height, one end of the coin 32 is placed on the overhang portion 70 and dropped in an inclined state. When the coin is inserted, the inclination becomes large, so that the probability of dropping the coin 32 is increased, and the coin 32 is smoothly discharged at the initial stage of coin insertion. After the coin 32 is dropped, the coin 32 'can be dropped into the position of the coin 32' in FIG. 3 because there is enough time, and if it is not possible, the coin 32 at the lowest position is If the coin 32 is discharged from the coin hole 62, the coin 32 is dropped to the lowermost position. Therefore, the coin 32 is dropped to the lowermost position, and the coin 32 is smoothly discharged.

The first contact surface 74 is inclined from the first contact surface 74 and is connected to a second contact surface 76 located on the outer peripheral side. The inclination angle of the first contact surface 74 is such that when the coin 32 is guided along the inner peripheral surface 42, the coin 32 is lightly applied to the inner peripheral surface 4.
The inclination angle of the second contact surface 76 is set so that the coin 32 in contact with the fixed roller 46 and the movable roller 48 is a line connecting the fixed roller 46 and the movable roller 48. Is set so that the direction component in the direction perpendicular to the direction becomes larger. The first contact surface 74 and the second contact surface 76 and the corner (corner) 78 located at the boundary between the first contact surface 74 and the second contact surface 76 are such that the guided coin 32 is
The corners 78 are set in such a shape that they come into contact with the coin 32 when they come into contact with the movable roller 48.

FIG. 4 is a view for explaining a state in which the coin 32 is fed by the driving projection 66. In the guiding process in which the coin 32 is guided along the inner peripheral surface 42, the coin 32 is moved only by being pushed by the first contact surface 74 like the coin 32a shown by the solid line and the one-dot chain line in FIG. In the sending process in which the coin 32 is sent to the outside of the inner peripheral surface 42, the coin 32 is pushed only by the second contact surface 76 as shown by the solid line and the two-dot chain line in FIG. The directional component is pushed to the outer peripheral side from the inner peripheral surface 42 with a larger thrust than the guiding process. The coin 32b is pushed by the second contact surface 76 until the center of the coin 32b crosses a line connecting the fixed roller 46 and the movable roller 48, and thereafter, the predetermined force is determined based on the urging force of the movable roller 48. The initial velocity is given to move the inside of the delivery groove 44 to the outer peripheral side.

The height and the initial position of the movable roller 48, that is, the position at the time of contact of the coin 32, are set so that the coin 32 is not jammed without using an inductor. That is, first, the height of the movable roller 48 is
In order to prevent the coin 32 from being caught between the movable roller 48 and the lower surface of the coin driving member 52, the setting is such that the coin 32 substantially contacts the lower surface of the coin driving member 52. Next, the coin 3 is placed between the movable roller 48 and the driving projection 66.
2 so that it is not bitten and is smoothly sent to the outer circumference side.
As shown in FIG. 4, the movable roller 48 is moved so that the center c of the coin 32 is located on the outer peripheral side with respect to a straight line L connecting the contact a of the coin 32 and the drive protrusion 66 and the contact b of the coin 32 and the movable roller 48. And the shape of the drive projection 66 are set. Further, in order to prevent the coin 32 from being stuck between the movable roller 48 and the coin hole 62, that is, to prevent the coin from being jammed, the moving locus of the movable roller 48 is set on the outer peripheral side of the outermost diameter of the coin hole 62. In addition, the position of the movable roller 48 and the position of the coin hole 62 are set.
