Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention is installed in a slot machine, a currency exchange machine, a vending machine for various products, etc., and is used to generate a required number of coins (including medals and other pseudo coins). This invention relates to an improvement of a hopper-type coin dispensing device used for dispensing coins (.).

<Prior Art> As a hopper type coin dispensing device most similar to the present invention, Japanese Patent Application Laid-Open No. 61-886 and Japanese Utility Model Application No. 61-4273 are known. In order to prevent the coin from getting stuck, the coin inductor (4) is configured to first transfer the coin (a) conveyed by the rotor (3) to the coin outlet (5). , its inductor (
4) is formed by a protruding element (15) that appears and retracts from the guide surface (14a) of the guide ring (14), and a spring (16) that pushes and biases the protruding element in the projecting direction.

Further, as the structure of the separator (6), which should transfer the coin (a) that was not successfully guided by the inductor (4) to the coin outlet (5), a swing plate (
The base end of the shaft (3) is planted and fixed on the base (11).
0) through a vertically long pivot hole (29), and a separate roller (
8) and an auxiliary roller (28) are supported in parallel, and the rocking plate (7) is urged toward the rotor (3) by a spring (9).

When the coin (a) gets stuck as shown in FIG.
8) resists the pulling force of the spring (9) and moves against the rotor.
(3) The coin (a) is guided and ejected to its delivery port (5) by receding straight to the side and moving left and right in a turning manner.

<Problems to be Solved by the Invention> However, despite the ideal explanation, the above configuration actually has the following problems.

First, regarding the coin inductor (4), it requires two parts: the retractor (15) and its push-up spring (16), and the processing of the special head shape of the retractor (15) is required. , a groove (37) for the blade (2) from which this should escape
) and the guide ring (1) together with the spring (16).
4) The work of assembling the product is extremely complicated, and the effectiveness of mass production is poor.

Moreover, a large number of coins (a) are usually stacked in the hopper (1), and the coins (a) are located in the hole (21) of the disk (20) while the coin (a) is placed in the rotor (3). ), there is a guide surface (14) on the conveyance path.
Since the infested child (15) in an upright state is facing from a),
Coin (a) suddenly appears during its Illll row (1
Collision with 5), and the coin outlet (5) at a steep angle from now on.
The direction will be changed to Since the flow of coin (a) is unreasonable and lacks overall smoothness, the force of trying to overcome the coin (15) will inevitably be f%.
<. As a result, irregular vibrations of the coin (a) are caused and a biting phenomenon is induced. From that meaning, Haunting Child (
It is also necessary to set the head shape of the head (15), its protruding position from the guide ring (14), the pressing force of the spring (16), etc. with high precision.

Next, regarding the separator (6), its rocking plate (7) functions only to guide and discharge the bitten coin (a) to the outlet (5), ensuring that it is delivered into the hopper (1). It does not have the function of smooth migration and return.

In other words, as is clear from the state shown in Figure 6, the attraction spring (
9) extends outside the straight line (L) connecting the center (T) of the coin (a), the center of curvature (V) of the blade (2), and the center (W) of the separate roller (8). Based on the fact that the straight line (L) is also located outside the axis (30) by a certain eccentricity it (E), the bitten coin (a) is placed on the separate roller ( 8) is not discharged from the outlet (5),
Inside the hopper (1) - Considering the case where the coin is transferred again, the coin (a) is positioned so that it is sandwiched between the separate roller (8) and the auxiliary roller (28) while being transported by the roller (3). Immediately, the retraction action of the rocking plate (7) and the delivery port (5) of its separate roller (8) occur.
Due to the escape turning action toward , coin (a) becomes base ff
1 (11) will be bitten into the notch recess.

The rocking plate (7) is connected to the base (11) only at its base end.
The coin (a
) is also caused by the fact that the receiving recess is cut out.

Means for Solving the Problems> The present invention aims to improve these problems and reliably prevent the coin-biting phenomenon, and for this purpose, a plurality of coins opened in a radially symmetrical arrangement is used. a disc rotor provided with a receiving hole and an arc-shaped radial blade piece located between adjacent ones; a rotational drive unit for the disc rotor; and a disc rotor fixedly installed on the drive unit to receive the disc rotor. A rotor receiving board that defines a recess and has a coin dispensing port facing the circumferential surface of the rogue, and a coin storage hopper that is fixedly installed on the rotor receiving board so as to communicate with the rotor receiving recess. A coin guide protrudes into the 1M coin feeding path caused by the rotation of the disc rotor and guides the coin toward the payout port, and a coin guide also receives the coins that are not guided by the derivative and changes the direction. A hopper-type coin dispensing device comprising a separator facing the l1fl feeding path, and configured to push and convey the coins received from the hopper to the disk rotor by the blades of the rotor and dispense them from the coin dispensing port. , the coin derivative is wound from a single metal wire into a substantially C-shaped eccentric ring surrounding the boss of the rotor;
The cut-off base end of the wire is used as a mounting leg piece to be fixedly locked in the rotor receiving recess of the rotor receiving block, while the free end of the cut-off wire is also used as a coin rectifying cam piece to approach the coin dispensing port. The first feature is that the relationship is set so that it gradually increases in size so that it does not overhang the coin river feed channel.Also, the coin derivative is similarly formed into a plate cam shape from an elastic material such as rubber or synthetic resin, and the rotor It is fixedly attached to the rotor receiving recess of the rotor receiving board so as to maintain a loose state with the boss, and the convex curved surface eccentric to the boss is used as a coin rectifying cam piece.
Coins gradually get bigger as you get closer to the coin payout port! The second feature is that the relationship is set so that it extends out to the general transportation route.

Furthermore, the structure of the separator is formed into a bendable link movement mechanism consisting of a pair of swinging link arms and a bending fulcrum pin that pivotally connects them to each other, and the thinking roller is made freely rotatable by the fulcrum pin. At the same time, both link arms are extended inward by a tension coil spring connected between one of the link arms and the rotor support so that the thinking roller always faces the coin feeding path. The coin, which is forced into a bent state and bitten into the thought roller so as to press it strongly, changes its direction so that it automatically moves into the rotor by the bending action of the two link arms that project outward. The third feature is that it is set so as to

Separate lake for importing and reverting
(S) is also assembled to the base plate (11) of the rotor receiving board (M).

The separator (S) is shown in Figures 19-22 and 29.
~ As shown in Figure 32, a pair of swinging link arms (52)
(53) are pivotally connected in a substantially dogleg shape that has a so-called center bending effect.

That is, one of the first link arms (52) is made of a metal plate with approximately the same thickness as the room plate (12),
From above in the center of the headspray 1- (11
) is rotatably assembled to the - corner of the frame by means of a pivot screw (54). (55) is a guide elongated hole for receiving the pivot screw (54), and is opened in the first link arm (52) as shown in Fig. 19.20.

The projecting edge is formed in an arc shape so as to be continuous with the above.

(57) is also the above-mentioned separation rake relief notch (34) from the first link arm (52) to the base plate (11).
) It is a roller support piece that is bent downward in an almost L-shape so as to face inward, and a thinking roller (59) is rotatably supported at its tip via a bending fulcrum pin (58). has been done. (60) is the roller support piece (57)
) under the bending ridge line perpendicular to the bending ridge line of
As an inverted letter shape pointing downward from the link arm (52),
This is a spring receiving piece bent outward of Hayspray 1-(11).

The other second link arm (53) is also rotatably attached to the base plate (11) from the opposite downward direction by means of a pivot screw (61), and moreover, by means of the refraction fulcrum pin (58), It is pivotably connected to the roller support piece (57) of the first link arm (52) in a bendable manner. (62) is an elongated hole for receiving the pivot screw (61) and is formed as an opening in the second link arm (53) as shown in Figs. 21 and 22.

(63) is a tension coil spring for biasing both link arms (52) and (53) in a dogleg shape that always extends inward, and is connected to the spring receiving piece (60) of the first link arm (52). , and a spring receiving pin (64) that hangs integrally from the base plate (11).

Therefore, the thinking roller (59) receives the urging force of the tension coil spring (63) and comes into contact with the notch edge of the separator relief notch (34) in the base plate (11), and the impact position The coin (C) is brought into contact with the coin (C) so as to receive the coin (C) conveyed by the disk loco (R).

(65) is a coin guiding piece that divides the opening width (W) of the coin dispensing port (O) into a constant by opposing each other to the thinking roller (59);
As shown in the figure, it is joined and fixed to the base plate (11) from above with a plurality of fixing screws (66). The head of the fixing screw (66) is allowed to escape through the screw relief hole (41) of the gate plate (13) and the screw relief notch (46) of the liner plate (14).

In this case, the opening width (W) of the coin payout opening (O) is always set to be wider than the size (diameter) of the coin (C). The coin guide piece (65) is also connected to the rotor receiving port (35) of the room plate (12) in the same way as the cover piece (56) of the first link arm (52).
As suggested from FIGS. 13.29 to 32, it has an arcuate overhanging edge that is continuous with the arc.

Further, a coin (C) counting lever (67) is also attached to the separator (S) as described above so that it can swing together. In other words, the count lever (6
7) consists of an L-shaped metal plate piece as shown in Figures 23 and 24, and its bending midway portion also serves as the bending fulcrum pin (58) and is rotatably pivoted to the separator (S). ing. (68) is a count roller rotatably supported by a pivot pin (69) to one end of the count lever (67) facing into the separator relief notch (34) of the base plate (11), As shown in FIG. 29, it is parallel to the outside position of the thought roller (59), but it protrudes so as to narrow the opening width (W) of the coin dispensing port (O), and Coins paid out (C

(70) is a tension coil spring that urges the count roller (68) to extend toward the coin dispensing port (O), and is a spring receiving piece ( 71) and the first link arm (5
The spring receiving piece (60) of 2) is interlocked with the spring receiving piece (60). The spring pressure of the tension coil spring (70) is relatively weak, whereas the spring pressure of the refraction biasing tension coil spring (63) of the separator (S) is set to be extremely strong.

The other end of the count lever (67) faces the negative corner of the base plate (11) and is blocked by a stopper piece (72) hanging from the corner. (73) is a sensor support piece that is integrated into the base plate (11) from below using the fixing screw (74) of the stopper piece (72). will be installed.

Next, FIG. 28 shows a modification of the coin derivative (A), in which the derivative (A) is molded from an elastic material such as rubber or synthetic resin into a plate cam shape with a C-shaped outline. At the same time, it is fixedly installed around the bearing hole (17) in the Hayspray (11) so as to maintain a loose state with the boss (25) of the disc rotor (R). The insertion hole (29a) of the coin guide (A), which is opened so as to correspond to the support pins (28a) that are integrally planted from the base plate (11), is inserted into the plurality of support pins (28a) so as to be freely inserted from above. It is attached.

Even in the coin derivative (A) configured in this way, the eccentrically protruding convex curved surface is the coin rectifying cam piece (3
0), the closer you get to the coin payout port (O), the larger the coin 1 will gradually protrude into the general feeding path, and the disc rotor (
In order to smoothly guide the coins (C) that are generally fed by R) to the coin dispensing port (O), the coiled metal wire is replaced with
It can be used without any trouble.

The coin rectifying cam piece (30) has a convex curved surface that eccentrically projects into the coin conveyance path.
It goes without saying that the cut-off edge portion (+2) is in a corresponding position 1 relationship that is approximately parallel to the concave curved surface of all.

<Operation> In the above configuration, when the disc rotor (R) is rotationally driven in one direction (f) by the motor (10) of its rotational drive unit l-(U), the disc rotor (R) is accommodated in the hopper (H). The coins (C) are received one by one into the coin receiving holes (23) of the rotor (R), and are held by the arcuate radial blades (26) of the rotor (R). , the coin 1 is transported so that it is pushed through the general transport path.

Since the coin derivative (A) overhangs the coin transport path, the coin (C) is transferred to the derivative (A).
), the coins are gradually pushed outward along the rectifying cam piece (30) of the coin dispensing port (O) as shown in FIG.
You will be guided to the coin payout port (O
) will definitely be paid out. When passing through the coin dispensing port (O), the coin always comes into contact with the count roller (68) as shown in FIG.
7) will be used for rotation, so the coin (C
) will be counted.

In that case, a room plate with a C-shaped cutout (12
) is separated from the coin rectifying cam piece (30
) is formed into a concave curved surface that recedes in accordance with the overhang of the coin (C), and the coin guiding piece (65) faces continuously with this, and the centrifugal force of rotation of the rotor (R) also acts on the coin (C). Therefore, the guiding action of the coin (C) toward the payout port (O) is extremely stable, and the coin (C) is paid out smoothly and reliably.

Also, lul! The coin regulating arm (51) hanging from the hopper (I) prevents the coin (C) from floating up or in an incorrect posture during feeding.

In Fig. 31, the circular center (X) of the coin (C) is the center (y) of the radius of curvature at the front convex curved edge of the wing piece (26).
and the refraction fulcrum pin (58) in the separate lake (S).
It happened to be located on the straight line (D-D) connecting the center (thought point) (2), and was caught between the thought roller (59) and the disc rotor (R), so to speak, in a tension state. It is assumed that

In such a case, the separator (S) is connected to the rotor (
When the coin (C) receives the rotational force of R), the coin (C) is subjected to an outward bending pushing force around the bending fulcrum pin (58) while resisting the tensile force of the tension coil spring (63). As a result, the coin (C), together with the thinking roller (59) which freely rotates in the counterclockwise direction shown in the figure,
As shown in FIG. 32, it is reliably transferred into the hopper (II) and returned, and is again subjected to the conveyance action by the rotor (R).

Even if the separator (S) is retracted to a slightly outwardly projecting state, the projecting edge of the cover piece (56) is connected to the cut-off edge ( Since it forms a concave curved surface that is continuous with b), the coin (C) is transferred extremely smoothly. In addition, as soon as the coin (C) is released from point contact with the thinking roller (59) during this process, the separator (S) immediately returns to its original inwardly bent state due to its strong tension coil spring (63). It goes without saying that it can be restored to.

Incidentally, when the coin (C) makes point contact with the thinking roller (59) of the separation rake (S) at a position that is even slightly deviated to the outside IJ11 from the above-mentioned imaginary straight line (D-D),
Coupled with the clockwise free rotation of the thinking roller (59), the direction of the coins is smoothly changed toward the coin payout port (O), and the coins are surely paid out. It will be counted.

30), the relationship is set so that the closer it gets to the coin dispensing port (O), the larger it gradually extends into the coin transport path. A coin derivative made of metal wire (
A), and even though it is sufficient to simply insert and lock it into the rotor receiving recess (G) (11) from above, the coin derivative (A) ) has the effect of reliably guiding the coin (C) to the coin dispensing port (O), and the first is the bending process and assembly into the rotor receiving recess (G). It is extremely easy to work with and has excellent mass productivity.

In particular, the rectifying cam piece (30) is curved so that as it approaches the coin dispensing port (O), it gradually protrudes into the coin conveyance path, so the disc rotor (R
), the coin (C) being sent to the general public can be smoothly and smoothly inserted into the coin dispensing port (O) without fear of suddenly colliding with other coins (C).
As a result, there is no need to worry about irregular vibrations of the coin (C) or the resulting jamming phenomenon, and the reliability of the entire device is improved. Even if (A) is formed from an elastic material such as rubber into a plate cam shape instead of bent from a single wire, the same effect can be achieved.

Moreover, due to its structure, the separator (S) is formed into a bendable link movement mechanism consisting of a pair of swinging link arms (52) (53) and a bending fulcrum pin (58) that pivotally connects them to each other. , the thinking roller (59) is rotatably supported by its fulcrum pin (5B), and both link arms (52) and (53) are attached so that the thinking roller (59) always faces the coin conveyance path. One first link arm (52) and rotor support ffi (M
) Tension coil springs (63
), the coin (C) is forced into a bent state that extends inward, and the coin (C) is bitten so as to strongly press the thought roller (59).
3) The setting is such that the direction is changed so that the outwardly projecting refraction action automatically moves the coin into the disc rotor (R).
Even if this occurs, the thinking roller (59) is strongly pressed by the coin (C), and both link arms (52) (53) extend outward while resisting the tension coil spring (63). As a result, along with the free rolling action of the thinking roller (59), the direction of the coin (C) is changed so that it is immediately and reliably transferred into the disc rotor (R). Paradoxically, there is no need to worry about causing a bite phenomenon at all. In order to remove the stuck coin (C),
There is no need for any artificial manipulation.

In any case, the coin (C) biting phenomenon can be completely prevented, and the configuration of the coin derivative (A) and separator (S) required for this purpose is much simpler than that of the conventional technology mentioned at the beginning. Therefore, it can be said that this is a practical invention that is particularly excellent in terms of reliability and mass production of the coin dispensing device.
