Description

  The present invention is installed in a typical slot machine of a gaming machine, a change machine, a change machine, a vending machine for various products, etc., and a required number of coins (in this specification, medals and other pseudo coins). It also relates to a hopper type coin payout device used for paying out.

In order to eliminate the need for a large, heavy and expensive motor with a reduction gear, a reduction gear that can rotate integrally with the disk rotor is installed as a rotational drive source for the coin conveying disk rotor in this kind of hopper type coin dispensing device. Means are disclosed in the following three patent documents, which are conventionally known.
JP-A-63-115295 Utility Model Registration No. 2527150 JP-A-10-261125

  However, in the second embodiment described in FIGS. 4 to 6 of Japanese Patent Laid-Open No. 63-115295, the teeth (32) carved on the outer peripheral surface of the disk (25) and the output from the electric motor (4) are first shown. The coin group in the hopper (1) is in a positional relationship in which the meshing surface with the gear (5) on the shaft (31) is exposed toward the peripheral edge of the lip (39) fitted to the hopper (1). Dust, metal powder, and other foreign matters mixed in are intensively transferred to the peripheral edge of the lip (39) by the rotational centrifugal force of the disk (25), and the teeth (32) and gears ( 5), it adheres and accumulates in a biting state on the meshing surface with 5), leading to an early rotation failure of the disk (25).

  On the other hand, in the first embodiment described in FIGS. 1 to 3 of JP-A-63-115295, a toothed circular ring (7) attached to the back surface (3) of the rotating member (2), and an electric motor The gear (5) on the output shaft (31) in (4) is meshed with a separate fixed central member (9) that fills the central opening of the rotary member (2) and its rotation. Since it is located corresponding to the mutual gap with the member (2), the rotation member (2) is still rotated due to the biting of the foreign matter, and in any case, frequent removal work of the foreign matter is performed. There is a problem that is forced.

  Next, in the case of utility model registration No. 2527150 proposed by the applicant of the present invention, the teeth of the circular ring plate (37) assembled and integrated to the lower surface of the perforated disc body (29) in the disc rotor (R). The diameter of the meshing surface of the (deceleration gear) (38) and the output gear (41) on the rotating shaft (40) of the drive motor (34) projects from the outer peripheral surface of the perforated disc body (29). Since this is covered from above by the circular cover flange (36), the problem described in JP-A-63-115295 can be improved.

  However, as a result of repeated studies after that, since the large circular cover flange (36) protrudes from the outer peripheral surface of the perforated disc body (29), the rotational centrifugal force of the disc rotor (R) is reduced. The problem is that the received coin (C) is likely to remain on the upper surface of the large circular cover flange (36), and the reduction gear (38) and the output gear (41). Since the meshing surface of the disk rotor (R) is positioned at a lower position than the forward transfer path of the coin (C) by the blade piece (30) of the disk rotor (R), foreign matter such as dust or metal powder attached to the coin (C) The problem that the meshing surface still tends to enter and accumulate in the biting state, and the meshing surface between the reduction gear (38) and the output gear (41) is a large circular shape of the perforated disc body (29). Cover flange 36), the output gear (41) of the drive motor (34) can be directly meshed with the reduction gear (38) unless it is from below the rotor receiving plate (M). This is not possible, and there is a problem that the layout of the assembly is restricted.

  The problem that foreign matters still tend to enter and accumulate in the cage and the problem that is restricted by the layout on the assembly is also true of Japanese Patent Laid-Open No. 10-261125.

  Also in Japanese Patent Laid-Open No. 10-261125, a reduction gear (4) is attached and integrated on the lower surface of a rotating body (3) that also carries coins, and the meshing surface between the reduction gear (4) and the transmission gear (2B). Is in the annular guide groove (12) at a lower position than the coin pushing forward conveyance path by the arc-shaped wall surface portion (3c) of the rotating body (3) and is shielded from above by the annular receiving member (10). Because.

  In that case, a certain gap must be ensured between the outer peripheral surface of the rotating annular receiving member (10) and the annular guide groove (12) in a fixed state. It is inevitable that foreign matter such as dust or metal powder enters and accumulates in the biting state on the meshing surface of the reduction gear (4) and the transmission gear (2B).

  The present invention aims to drastically solve such various problems, and in order to achieve the object, in claim 1, a mounting body in which a circular rotor receiving concave step surface is recessed on the upper surface,

  A rotor main body board having a U-shaped cross section having a plurality of coin receiving openings cut out in an overall radially symmetric distribution type and a plurality of rear bent blades continuously projecting downward from adjacent to each other. A disk rotor for coin transfer fitted from above into the concave receiving surface of the fuselage of the fuselage;

  In order to rotate the disk rotor, a drive motor attached to and integrated with the installation body,

  A coin receiving hopper that is attached and fixed to the upper surface of the installation body in a state of communication opening with the rotor receiving concave step surface, and that restrains the coin receiving flange at the peripheral edge of the disk rotor from being pulled out from above;

  A coin guiding pin that guides the coin to a coin payout opening cut out on the upper surface of the installation body;

  Hopper-type coin dispensing device that pushes and conveys coins taken from the coin receiving hopper into the coin conveyance path through the coin receiving port of the disk rotor by the backward curved blades of the rotating disk rotor and sequentially dispenses from the coin dispensing port In

  A large-diameter circular input gear is assembled and integrated on the lower surface of the rotor main body board, and a plurality of coin receiving openings that match and communicate with the coin receiving opening of the rotor main body board are cut out on the input gear, and the rotor main body board is cut out. While projecting the above-mentioned rear bent blade from the lower surface of the input gear into the coin conveyance path,

  The input gear serving as the final reduction gear and the output gear having the smallest diameter of the drive motor are engaged with each other via the first intermediate transmission gear having a large diameter on the idle shaft and the second intermediate transmission gear having a small diameter.

  The meshing surface of the second intermediate transmission gear and the input gear is shielded from above by the hopper.

Further, in claim 2, on the premise of claim 1 above, the mounting bracket to the installation body is preliminarily attached to the drive motor as an attached unit, and the mounting bracket is connected to the output shaft of the drive motor by an idle shaft. 1 and 2, while supporting the intermediate transmission gear rotatably,

When the mounting bracket of the drive motor is assembled and integrated with the installation body, the second intermediate transmission gear is set so as to properly mesh with the input gear.

Further, in claim 3, on the premise of claim 1, the constant depth of the U-shaped rotor main body board is dimensioned as a numerical value obtained by adding about half of the thickness of the coin to the plurality of coins. It is said.

According to the above configuration of claim 1, a circular shape having a diameter larger than that of the rotor main body of the disk rotor for coin conveyance is supported by the input gear integrated with the lower surface of the rotor main body and the idle shaft. The meshing surface with the second intermediate transmission gear having a small diameter is shielded from above by the coin storage hopper.

In addition, the input gear is cut out with a coin receiving port that matches and communicates with the coin receiving port of the rotor main body board, and the rear bent blade of the rotor main body board passes through the outlet for the rear bent blade of the input gear. Therefore, the meshing surface of the input gear and the second intermediate transmission gear is inevitably positioned at the upper stage of the coin conveyance path by its backward curved blades. .

As a result, foreign matter such as dust and metal powder mixed in the coin group in the hopper does not enter and adhere to the meshing surface of the input gear and the second intermediate transmission gear, and is incidental to each coin. There is no risk of the foreign matter entering and accumulating on the meshing surface, and there is an effect that the rotation of the disk rotor and the coin payout action can be kept normal throughout.

The input gear attached as a final reduction gear to the rotor main body and the output gear having the smallest diameter of the drive motor for rotating the disk rotor are the same as the first intermediate transmission gear having a large diameter on the idle shaft and the diameter. Since it is meshed via a small second intermediate transmission gear, there is an effect that the desired required reduction ratio can be easily obtained by selecting the number of teeth in the plurality of intermediate transmission gears.

And if the structure of Claim 2 is employ | adopted, the attachment bracket to the installation fuselage is beforehand made into the attachment unit to the said drive motor, and the said attachment bracket is connected via the idle shaft parallel to an output shaft, the above-mentioned Since the first and second intermediate transmission gears are pivotally supported, the assembly operation of the drive motor to the installation body can be performed quickly and conveniently, and the second intermediate transmission gear and the input gear can be engaged with each other accurately and accurately. Can do.

Further, if the configuration of claim 3 is adopted, coins dropped from the coin receiving hopper into the rotor body board are stacked and receive the rotational centrifugal force of the disk rotor. The coin is received by the coin receiving flange of the board, and there is no possibility that the coin enters the biting state into the mutual gap between the coin receiving flange and the hopper that restrains the coin receiving flange from above. From this point of view, the rotation of the disc rotor and the coin payout action can always be maintained normally.

Hereinafter, a specific configuration of the present invention will be described in detail with reference to the drawings. In FIGS. 1 to 16 showing the first embodiment of the hopper type coin payout device, (M) is a high level of ABS resin, polycarbonate, FRP or the like.

The mutual interval (W) facing each other is dimensioned to be narrower than the diameter of the coin (C). (27) is a plurality of foreign substance drop openings which are cut out and distributed in the middle of the flat groove bottom surface of the base plate receiving concave groove (7), preferably in an elongated arc shape.

As shown in FIGS. 5 and 7, the base plate (8) mentioned above is composed of a metal disc having a constant thickness substantially corresponding to the constant depth (g2) of the base plate receiving concave groove (7). In addition to a rotating support shaft (28) of a coin-carrying disk rotor (R) which will be described later being caulked and integrated in an upright state, the base plate receiving groove (7) is also formed in the peripheral portion of the base plate (8). A plurality of fitting notches (29) corresponding to the positioning ridges (12) for the base plate on the side are also provided.

Needless to say, it extends in a circular arc shape corresponding to the rear curved blade (42) on the board (32) side.

In this case, the rear curved blade (42) on the rotor main body board (32) side passes through the rear curved blade escape port (48) of the input gear (33), and the coin ( C) is overhanging by a constant dimension (T) substantially equal to the thickness of C), and the escape tunnel (49) of the coin guide pin (15) is notched at the lower end of the overhang of the rear curved blade (42). It has been.

Further, the head of the fixed screw (45) for assembling and integrating the rotor main body plate (32) and the input gear (33) is in a state where the head is depressed from the flat bottom surface of the rotor main body plate (32). However, the tip of the fixed screw (45) also protrudes from the lower surface of the input gear (33) by a constant dimension (T) substantially equal to the thickness of the coin (C).

Then, as shown in FIGS. 10 to 13, a spacer plate (50) is fitted and locked to the lower end of the fixed screw (45) as shown in FIGS. Furthermore, the spacer plate (50) defines a coin transport path (P) having an opening width (S) slightly wider than the diameter of the coin (C) between the inside and outside of the spacer plate (50) facing the base plate receiving concave groove (7). As an object, a plurality of (four in total in the figure) arc-shaped screw acceptors which are made of a metal disc having a size circumscribing the coin receiving port (47) of the input gear (33) and distributed at the periphery thereof. The mouth (51) is engaged with the fixed screw (45) so as to keep the surface contact with the input gear (33).

In addition, (52) is a rotation support shaft outlet cut out at the center of the spacer plate (50), and (53) is the spacer plate (50) and the base plate (8) in the installation body (M). Is a thin synthetic resin washer that is interposed between the rotating spacer plate (50) and the fixed spacer plate (8) to prevent friction between the rotating spacer plate (50) and the fixed base plate (8).

The drive motor (40) of the coin conveying disk rotor (R) includes a working base (54) of an aluminum die-cast mounting bracket (B) as shown in FIGS. 14 and 15, and a plurality of fixing screws (55). It is an attached unit in advance. (56) is the smallest output gear fixed on the output shaft (57) of the drive motor (40), and (58) and (59) are idle shafts (60) parallel to the output shaft (57). A large-diameter first intermediate transmission gear that is rotatably fitted into an inverted U-shaped enclosure (61) that stands integrally from the base (54) of the mounting bracket (B) via And a second intermediate transmission gear having a small diameter, and a lower first intermediate transmission gear (58) is maintained in mesh with the output gear (56). (62) is a needle bearing fitted to the idle shaft (60), and (63) is a reinforcing brace for connecting the platform (54) and the surrounding frame (61).

As is apparent from FIGS. 4 and 5, the mounting bracket (B) of the drive motor (40) passes through the motor enclosure cover (4) in the installation body (M), and the motor mounting bracket escape port ( 10) A long fixing bolt (65) inserted into the plurality of bearing bosses (64) in the figure from the lower side and scattered from the opposite upper side to the peripheral edge of the base plate (54). Is fixedly integrated in a suspended state to the installation body (M).

Under such an assembled state, the second intermediate transmission gear (59) having a small diameter on the upper stage supported by the mounting bracket (B) is connected to the input gear having the largest diameter on the disk rotor (R) side ( 33) and the disc rotor (R) can be decelerated and rotated by the drive motor (40), and the assembly work to the installation body (M) can be performed conveniently. (G) generically refers to the speed reduction mechanism.

In this regard, in the speed reduction mechanism (G) shown in the figure, the output gear (56) is a spur gear that runs through the output gear (56), the first and second intermediate transmission gears (58) (59), and the input gear (33). The speed of the input gear (final reduction gear) (33) can be reduced from about 3600 rpm to about 120 rpm, but the reduction ratio is determined by these gears (56) (58) (59) ( 33) and the selection of the first and second intermediate transmission gears (58) and (59) can be easily adjusted.

(H) is a coin receiving hopper, which is made of a synthetic resin similar to the above-described installation body (M) and integrated into a funnel type having a leg seat (66) that is in close contact with the upper surface (1) of the installation body (M). The upper end of the molded body is then attached to the support stay (3) for the hopper of the installation body (M) via a horizontal pivot pin (67) so as to be able to turn up and down. The front lower end of the hopper (H) is fastened to the hopper receiving seat (2) of the installation body (M) by a fixing screw (68). By such a leg seat (66) of the hopper (H), the coin guide plate (26) of the installation body (M) is also constrained and fixed in a covered state from above, so that the coin guide plate (26) comes out. There is no fear.

(69) is an opening bottom surface of the hopper (H), which is in communication with the base plate receiving groove (7) on the installation body (M) side, and receives the coin of the disk rotor (R) from its opening edge. A restraining flange (70) that can restrain the flange (34) from above is projected inward. (71) is a relief notch for the motor mounting bracket provided to the leg seat (66) of the hopper (H).

In this case, as is apparent from FIG. 5, the large input gear (33) projecting from the rotor body panel (32) of the disk rotor (R) and the mounting bracket (B) of the drive motor (40) are provided. The meshing surface with the shaft-supported second intermediate transmission gear (59) is shielded from above by the hopper (H), and the lower position of the meshing surface is the rear curve of the disk rotor (R). Since the coin (C) is pushed forward by the blade (42) and is defined as a conveying path (P), not only foreign matters such as dust and metal powder mixed in the coin (C) group in the hopper (H) are of course used. The foreign matter attached to the coin (C) is not likely to enter and accumulate in the biting state on the meshing surface.

Further, since the coin receiving flange (34) that forms the peripheral edge of the disc rotor (R) is restrained from being pulled upward by the inward restraining flange (70) of the hopper (H), the above-described installation body Into the base plate receiving concave groove (7) of (M), the unit base plate (20) of the coin count unit (U) and the metal plate spring (21) of the coin guide pin (15), the base plate (8), the spacer plate from above.

Furthermore, a constant depth (g3) of the rotor body board (32) having a U-shaped cross section (in other words, the height of the coin receiving flange (34) standing up relative to the depression). Is preferably sized as a numerical value obtained by adding approximately half of the thickness of the coin (C) to a plurality of coins (C).

Then, the coin (C) received in the laminated state inside the rotor main body board (32) receives the rotational centrifugal force of the disk rotor (R), but the coin receiving flange at the peripheral part is unavoidable. (34) is inserted into the inter-gap between the upper surface of the coin receiving flange (34) and the inward stop flange (70) of the hopper (H) that shields the coin receiving flange (34) from above. There is no such thing, and rotation failure of the disk rotor (R) can be prevented.

The coin count unit (U) mentioned earlier is an assembled unit product of the count arm (72) and the separate arm (73) as extracted in FIG. 16, and the middle part of both arms (72) (73). Is pivotally attached to a common swing fulcrum shaft (74) integrally projecting downward from the unit base plate (20) so as to be able to perform a separate and independent swing action.

In addition, a freely rotatable count roller (75) is pivotally supported at one end of the count arm (72), and the other end of the count arm (72) is also used as a detection piece (76) to transmit light. It is detected by a mold count sensor (77) and counts the number of coins (C) to be paid out.

(78) is a tension spring hung between the other end of the count arm (72) and the middle part of the unit base plate (20), and a stopper (23) on the installation body (M) side. ) Each time the count roller (75) positioned and urged to the reference state of overhanging the coin payout slot (9) comes into contact with the coin (C) passing through the coin payout slot (9), the coin ( C) is counted one by one by the count sensor (77).

On the other hand, the separate arm (73) guides the bitten coin (C) to the coin payout opening (9) in a correct manner, or again by the disc rotor (R) to the coin transport path (P). The separation roller (79), which is pivotally supported in parallel with the count roller (75) at one end thereof, once receives the bitten coin (C). Swiftly as if they were distributed to themselves. Similarly, (80) is a tension spring hung between the other end of the separate arm (73) and the middle part of the unit base plate (20), and the tension spring (78) on the count arm (72) side thereof. The separation roller (79) is urged so as to face the circumferential surface of the coin transport path (P) by a tension stronger than ().

In the hopper type coin payout device configured as described above, the coin conveying disk rotor (R) is driven by its drive motor (40), so that the output gear (56) and the first and second intermediate transmission gears (58) (59). Further, when rotated clockwise (F) in FIG. 4 via the input gear (33), the coin (C) accommodated in the coin accommodating hopper (H) is self-recognized by the disc rotor (R). Through the coin receiving port (41) and the coin receiving port (47) of the input gear (33), it is taken into the coin conveyance path (P) defined at the lower position thereof and protrudes downward from the disk rotor (R). The inside of the coin conveyance path (P) is pushed forward toward the coin guide pin (15) by the rear curved blade (42).

The coin guide pin (15) stands up inside the coin conveyance path (P), but is positioned corresponding to the vicinity of the coin payout opening (9), and the upper edge of the opening of the coin payout opening (9). Since the count roller (75) of the coin count unit (U) and the coin guide plate (26) face each other at the lower edge of the opening, they are pushed forward and conveyed by the disk rotor (R). The coin (C) is eventually guided by the coin guide pin (15) so as to change its direction from the coin transport path (P) to the coin payout slot (9), and the disk rotor (R) acting on the coin (C) ) In combination with the rotational centrifugal force, the coins are smoothly and sequentially paid out from the coin payout opening (9).

The coin (C) in the payout process is placed on the count roller (75) and the coin guide plate (26) in the protruding reference state facing each other while keeping a mutual interval (W) narrower than the diameter of the preliminarily coin (C). The count arm (72) is brought into contact with the urging force of the tension spring (78) and is swung to spread around the swing fulcrum shaft (74). The number of coins (C) to be paid out is accurately counted by the count sensor (77) that detects the detection piece (76).

In the first embodiment described with reference to FIGS. 1 to 16, the coin-carrying disk rotor (R) is driven from the vicinity of the rear upper end of the installation body (M) having a front-declining slope of a predetermined angle (α). Since the motor (40) is in a suspended positional relationship, it is possible to shape the installation body (M) to a position where the virtual line (XX) in FIG. 2 is the bottom surface.

In particular, as shown in the second embodiment of FIG. 17, the upper surface (1) of the installation body (M) is a horizontal plane, and the drive motor (R) for the disk rotor (R) for coin conveyance from above is installed on the installation body (M). 40) in an inverted state opposite to that of the first embodiment, when the size of the coin receiving hopper (H) is made constant, the entire hopper type coin payout device is flat and very low. As a result, for example, a game effect lighting screen or the like can be installed without restriction on the surface of a slot machine incorporating and using the same, and the degree of freedom in layout is reduced.

Also in the second embodiment of FIG. 17, the output gear (56) of the drive motor (40) is connected to the input gear (33) on the disk rotor (R) side via a plurality of intermediate transmission gears (58) (59). The disc rotor (R) can be rotated at a reduced speed, and the input gear (33) and the second intermediate transmission gear (59) located above the coin transport path (P) are engaged with each other. Of course, the meshing surface is shielded from above by the coin receiving hopper (H). Since the other configuration is substantially the same as that of the first embodiment, only the corresponding reference numerals to those in FIGS. 1 to 16 are written in FIG. 17, and the detailed description of the second embodiment is omitted.
