Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial application field) The present invention relates to a ball discharging device for a pachinko machine, which can be applied to many conventional and pachinko machines expected to be developed in the future. Things.

(Prior Art) In a pachinko machine, when a game ball enters a winning opening, a predetermined number of balls are discharged to a saucer. It takes a predetermined time to discharge this prize ball, and in recent years, techniques for shortening this time have become active. By the way, there are at least the following two methods in the current ball discharge device. The first method is to make the passage through which the discharged balls pass only one ball at a time (a cross-sectional dimension that does not allow two balls to pass at the same time), and to place a solenoid at any position above and below the passage. A stopper (shutter) that protrudes due to the like is provided.

In this system, the upper stopper is opened with the lower stopper closed, and the ball flows into the passage from above,
When a predetermined number of balls have been introduced and reach the upper stopper, the inflow of the balls is stopped, and then the upper stopper is closed and the lower stopper is opened, so that the upper and lower stoppers are interposed. A predetermined number of stored balls are discharged. In this method, a predetermined number of balls can be secured between the upper and lower stoppers.

An advantage of this method is that when the upper and lower stoppers are opened and closed so as to be mechanically linked, discharge of a predetermined number or more of balls (referred to as outflow for convenience) can be reliably prevented.

The other type does not provide a stopper at the upper part of the passage, but only provides a stopper at the lower part, and detects the number of balls ejected by a sensor when opening the stopper provided at the lower part. It is. That is, since no stopper is provided in the upper part, the balls are always stored in the passage to the lower stopper, and when the prize is won, the lower stopper is opened and the number of balls is counted by the sensor when discharging. is there. This method has the advantage that the ball is always in the passage, so that no preparation time is required and the response is good.

(Problems to be Solved by the Invention) As described above, in the ball discharging device of the pachinko machine, the stopper is provided in the passage of the ball, and the stopper is opened and closed by driving the solenoid mechanism. The ball is discharged. However, since the opening and closing of the passage by the stopper is performed by driving the solenoid mechanism to move the stopper, in order to maintain the open or closed state of the passage,
There has been a problem that the solenoid has to be continuously excited for a long time, and the power consumption increases. Further, in order to accurately discharge the desired number of balls, the stopper must be closed immediately after the desired number of balls have passed through the stopper. Therefore, the response speed of the solenoid mechanism must be increased. For this reason, when the elasticity of the spring of the solenoid mechanism is increased, there has been a problem that a large amount of power is consumed for sliding the plunger.

Therefore, the present invention has been made in view of this point. By reducing the power of the solenoid mechanism and improving the response speed of the solenoid mechanism, the power consumption is suppressed and the desired number of balls can be accurately determined. It is an object of the present invention to provide a ball discharging device of a pachinko machine capable of discharging the ball to a machine.

(Means for Solving the Problems) According to the present invention, as a means for solving the above problems, in a ball discharging device of a pachinko machine 1 for discharging a predetermined number of balls 12, a ball for causing the balls 12 to flow down to a predetermined position is provided. Passage 11 and stopping means 15, 29 capable of stopping the flow of the ball in the passage 11 of the ball 12
And a latching solenoid 35 arranged near the passage 11 of the ball 12 and interlocking the stopping means 15 and 29. The latching solenoid 35 is provided in the latching solenoid 35 by energizing for a predetermined time. The plunger 43 is slid to a predetermined position to activate the stopping means 15 and 29 to stop or start the falling of the ball 12, and the plunger 43 keeps the predetermined time even after the end of the power supply for the predetermined time. It can be held at a position.

(Operation) With such a configuration, the latching solenoid 35
When the power is supplied for a predetermined time, the plunger 43 is slid to a predetermined position, and the stopping means 15 and 29 are operated to stop or start the falling of the ball 12. The latching solenoid 35 allows the plunger 43 to slide to a predetermined position due to energization, and even after the energization ends, the plunger 43 can be held at the predetermined position after the sliding.
In the projecting or sucking state after sliding the 43, the state (ie, the projecting or sucking state of the plunger 43) is maintained without consuming power.

15 are provided. Explaining from the stopper mechanism 15 for convenience, a notch is provided between the ball removing member 91 and the connection gutter 87 (FIG. 16).
21 (FIG. 1) is provided, and a first sprocket 22 is provided so as to partially enter the notch 21.

The first sprocket 22 is formed integrally with the ratchet 23 and the rotating plate 104, and is attached to the support shaft 24. The teeth 105 of the ratchet 23 and the detection holes 106 of the rotating plate 104 are provided by the number corresponding to the concave portions 25 of the first sprocket 22, and are indicated by arrows by fitting the balls 12 descending into the concave portions 25 one by one. As shown in FIG.

Is discharged to the upper receiving tray 4 through the connecting gutter 87. When a predetermined number of prize balls corresponding to the winning and the lending balls corresponding to the amount are discharged, the discharge is stopped by a solenoid mechanism 35 described later.

The ratchet 23 has an arm that rotates around an axis 26.
A claw 29 as stopping means formed on the first member 28 of 27 is exposed. The arm 27 as a transmission mechanism includes a first member 28 having a claw 29 and a second member 30 that rotates about the same shaft 26. Details of this part are shown in FIGS.
Description will be given including the drawings. First member 28 constituting arm 27
And the second member 30 are provided with L-shaped projections 31 and 32, respectively. The projections 31 and 32 are engaged with both ends of a coil spring 33 having an intermediate portion wound around the shaft 26. I have.

By the coil spring 33, the first member 28 and the second member 30 are urged in the approaching direction. A shaft 34 protrudes from an intermediate portion of the second member 30, and a lower end of a plunger connection arm 36 protruding from a solenoid mechanism 35 is mounted on the shaft. A weight 37 urges the second member 30 with a counterclockwise force in FIG. A latching solenoid is used for the solenoid mechanism 35.

As shown in FIGS. 1 and 2, a horizontal link 47 that rotates about an axis 46 is provided on the upper part of the arm 27, and a step 48 formed on a part of the horizontal link 47 is provided on the arm 27. 27
The position is set so as to be able to come into contact with the mounting portion of the weight 37. The lower end of a vertical link 50 is axially attached to an end of the horizontal link 47 opposite to the shaft 46 by a shaft 49.
A second arm 52, the tip of which is formed on a claw 51, is mounted on the upper end of 50 by a shaft 53. The second arm 52 is supported by a shaft 54, and rotates about the shaft 54. . A stopper pin 55 is provided at a portion adjacent to the guide path 11 so as to restrict the rotation range of the second arm 52.

The guideway 11 is provided with a notch 57 (FIGS. 1 and 3) for allowing a part of a second sprocket 56 described below to face the guideway 11. The sprocket 56 is positioned so as to face a concave portion 58 on the outer periphery, and is provided so as to rotate about a shaft 59. The shaft 59 is inserted into the boss 110 from the wall surface 109 of the guideway 11. One end of the shaft 59 is a bearing of the mounting frame 97.
111 (FIG. 2).

On the shaft 59, a small-diameter gear 60 that rotates integrally with the second sprocket 56 is supported.
Gear 60 on the outflow prevention device 20 side through a through hole 112 '
Gear gear 61 having about three times the number of teeth. The gear 61 rotates around a rotation support shaft 62 inserted into a mounting frame 97 of the outflow prevention device 20,
A first plate 63 is provided on a side surface of the gear 61 so as to rotate integrally with the gear 61. The rotating shaft 62 has a first
The second plate 64 is supported adjacent to the plate 63 of FIG.
The second plate 64 is rotatably supported by the rotation support shaft 62, and therefore, is suspended by its own weight in a free state.

The second plate 64 has a projection 65 facing the first plate 63.
(See FIG. 11, which will be used in the following description of the operation.) By increasing the number of teeth of the gear 61 with respect to the gear 60 at an appropriate ratio, the number of rotations of the first plate body 63 is reduced. The protrusion 65 is scooped by the first plate 63 and rotates at the ratio of 1. The claw 51 formed at the tip of the second arm 52 faces the second plate 64.

As a result, the second arm 52 rotates in a state where the second plate 64 is scooped and rotated by the first plate 63, and the claw 51 is rotated.
Projecting toward the shaft 62, it projects in front of the second plate 64 that is rotating at that time, and by engaging with this, the rotation is prevented.

The thus configured device operates as follows. In the state shown in FIG. 1, a predetermined number of balls
Is in the state where the stopper mechanism 15 is operated and the dispensing of the ball 12 is completed, and the solenoid mechanism 35 is operated to pull up the plunger connection arm 36 as a transmission mechanism together with the plunger 43, and to the first member 28 of the arm 27 Provided claw
29 is where the ratchet 23 is engaged. When the claw 29 is engaged with the ratchet 23, the first
The sprocket 22 is also prevented from rotating, so that the ball 12 does not flow downward therefrom.

Next, the solenoid mechanism 35 will be specifically described in detail.
As shown in FIGS. 2 and 6, the main body frame 113 of the solenoid mechanism 35 is formed of a U-shaped metal plate, and the main body frame 113 is mounted on a metal mounting plate 38. Then, the suction coil 40 and the return coil 41 are wound in two layers in the main body frame 113, and are energized independently of each other. A fixed iron core 39 is fixed to the body frame 113 at the upper part.

A plunger 43 is provided in the body frame 113, and a coil frame 114 is interposed between the plunger 43, the suction coil 40, and the return coil 41. The plunger 43 is inserted into the hole 42 so as to be able to move forward and backward, and the suction coil 40 and the return coil 41
A magnet 45 (permanent magnet) is provided at the lower part of. The distal end of the plunger 43 is covered with a resin member 44, and is connected to the plunger connection arm 36 by a pin 115. The resin member 44 at the tip of the plunger 43
When abuts against the stopper portion 116 of the metal mounting plate 38, a gap L is formed between itself and the tip of the plunger 43 (see FIGS. 8 and 9). This is to adjust the magnetic flux (magnetic force) acting on the plunger 43 of the magnet 45. 6 to 9 are drawings so that the relationship between the solenoid mechanism 35 and the stopper mechanism 15 can be easily understood.

Next, the operating state of the solenoid mechanism (latching solenoid) 35 will be described based on FIGS. 6 to 9 based on the discharge of award balls. FIG. 6 shows a state in which no electricity is supplied together with the suction coil 40 and the return coil 41, and the claw 29 of the arm 27 is ratcheted.
23 shows a state where the discharge of the prize ball is stopped. In the non-energized state, the plunger 43 is attracted to the fixed iron core 39 by the magnetic flux (magnetic force) of the magnet 45 in the direction indicated by the dotted arrow, and the holding force (attractive force) FP1 of the plunger 43 is
FP1> FS1 which is larger than FS1 due to the weight of each member added to 3 and plunger 43.

Next, FIG. 7 is an explanatory diagram until the plunger 43 projects. 15 and 16, the game ball that has won the winning opening 66 and the winning device 67 passes through the winning ball passage 84, and the main body control circuit 17 sends a short pulse (50 ms to 100ms), a magnetic flux is generated in the direction of the solid line arrow, a magnetic flux is generated in a direction to decrease the magnetic flux (magnetic force) of the holding force FP1 in the direction of the dotted arrow by the magnet 45, and the magnetic flux (magnetic force) of the magnet 45 is The force is weakened, and finally the reversal of the force of FP1 <FS1 occurs, and the plunger 43 projects. As a result, the engagement between the ratchet 23 and the claw 29 is released, and the state shown in FIG. 8 is reached, and the prize ball is discharged.

FIG. 8 is a view showing a state in which the prize ball is being discharged. The resin member 44 at the tip of the plunger 43 is connected to the stopper portion 116 of the metal mounting plate 38.
, And protrudes by the stroke S. In FIG. 7, the plunger 43 can protrude by overcoming the force of the holding force FP1, and after the energization of the return coil 41 is cut off,
In order to keep the plunger 43 in the protruding state, the holding force directed downward of the plunger 43 must overcome the force pulled back by the magnet 45 (the force due to the magnetic flux in the direction of the dotted arrow) FP2. For this purpose, the magnet 45 and the stopper portion 116 of the metal mounting plate 38 form a magnetic circuit indicated by a chain line. As described above, the resin member
Leakage magnetic flux is generated between the mounting plate 38 and the mounting plate 38, and an appropriate holding force FS2 is obtained.

Next, referring to FIG. 9, a transition state when the suction coil 40 is energized from the protruding stationary state (non-energized state) of the plunger 43 in FIG. 8 will be described. When the detection sensor 107 detects that a predetermined number of prize balls have been discharged, the main body control circuit
17 transmits a short pulse (50 ms to 100 ms) to the suction coil 40. Since the attraction coil 40 is wound so as to generate a magnetic flux in a direction opposite to that of the return coil 41, it generates a magnetic flux in a direction indicated by a solid line arrow and is added to a magnetic flux generated by a magnet 45 (a direction indicated by a dotted arrow). Since the suction force FP3 is generated and becomes larger than the holding force FS2, the plunger 43 is sucked. As a result, the ratchet 23 and the claw 29 are engaged, and the discharge of the prize ball is stopped.

As described above, the solenoid mechanism 35 operates in such a manner that a pulse current is alternately passed through the attraction coil 40 and the return coil 41, so that the plunger is operated together with the action of the magnet 45.
A latching solenoid is used that retracts 43 and plunger connection arm 36 so that it can stop at the raised and lowered positions.

As shown in FIG. 1, when the solenoid mechanism 35 is operated, the arm 27 rotates counterclockwise, and the claw 29 is engaged with the ratchet 23, the horizontal link 47 located above the arm 27 is
Is pushed up by the second member 30 of the arm 27 by the step portion 48, and this force overcomes the weight of the vertical link 50, and the second arm 52 also rotates counterclockwise about the shaft 54. I do. In this manner, the pawls 51 deviate from the rotation trajectory of the second plate body 64 and do not prevent the rotation. As a result, even if the second plate 64 is scooped and rotated by the first plate 63, the second sprocket 56 is not affected at all.

The arm 27 is divided into a first member 28 and a second member 30. These are connected to projecting pieces 31, 32 provided on the respective members by coil springs 33 whose both ends are locked. Ratchet 23 in which claw 29 provided on 28 is rotating
Even if a shock is applied to stop the engagement, the shock is absorbed by the coupling portion of the coil spring 33, and the transmission to the solenoid mechanism 35 side is significantly reduced. Thereby, the subsequent operation is performed smoothly.

The solenoid mechanism 35 is thus connected to the plunger connection arm.
Since the stop is performed at both the raised position and the lowered position, the plunger connection arm 36 may be in a protruding state when a power failure occurs during a game due to a bad power. No.
Figure 10 shows the state at that time. In such a case, the prize ball discharging mechanism of the stopper mechanism 15 fails, but the horizontal link 47 rotates clockwise around the axis 46 due to its own weight of the vertical link 50 and the like, and the vertical link 50 also loses its own weight. , And the second arm 52 is rotated clockwise around the shaft 54 until the second arm 52 comes into contact with the stopper pin 55. As a result, the claw 51 projects into the rotation locus of the second plate 64.

This will be described with reference to FIGS. 11 to 14. As described above, the first plate 63 is integrally attached to the gear 61,
The second plate 64 is rotatably supported by the rotation support shaft 62. The claw 51 of the second arm 52 is provided at a position where it comes into contact with and engages with the second plate 64 when the plunger 43 projects (FIG. 10).

Under such conditions, when the gear 61 rotates clockwise as shown by the arrow, the first plate 63 scoops up the second plate 64 that is hanging down by its own weight. FIG. 11 shows a state in which the plunger connection arm 36 is sucked together with the plunger 43 (the same as in FIG. 1), and the claw 51 does not protrude into the rotation locus of the second plate 64, and therefore, The pawl 51 does not engage with the second plate 64.

In the state shown in FIG. 11, the pawl 51 does not engage with the second plate 64, so that even if the first plate 63 scoops up the second plate 64, there is no rotation of the gear 61. There is no problem. if,
Even when the solenoid mechanism 35 projects the plunger connection arm 36 together with the plunger 43, it stops due to a power failure or the like, and the claw 51 of the second arm 52 projects into the rotation locus of the second plate 64 ( (See FIGS. 10 and 12),
When the first plate 63 scoops up the second plate 64 (twelfth
When the state shown in FIG. 13 changes from the state shown in FIG. 13) to the state shown in FIG.
As shown in the figure, when the second plate 64 starts rotating (to be precise, the second plate 64 rotates and falls by its own weight from the state of FIG. 13,
This means that the first plate 63 integrated with the gear 61 comes later and pushes the back of the second plate 64).
The claw 51 protruding forward of the 64 abuts and engages the second plate 64 and prevents rotation of the gear 61 via the first plate 63 abutting from the back. .

Therefore, the second sprocket 56 stops via the large-diameter gear 61 and the small-diameter gear 60, and the outflow of the ball 12 is prevented. The large-diameter gear 61 is
Since the gear 60 is rotated at a reduced speed, for example, at a ratio of 1: 3 with respect to the small-diameter gear 60 (see FIGS. 1, 2 and 10) integral with 56, the number of the recesses 58 of the second sprocket 56 is appropriately (That is, the number when tripled is close to the maximum emission amount,
By slightly increasing the number, the ball 12 discharge prevention function of the second sprocket 56 can be set to a number substantially matching the maximum discharge amount.

The embodiment described above is for the case where the present invention is ejected when the ball enters the winning opening, but the present invention is not limited to this, and as described above, When the pachinko machine is provided with a ball lending function, the present invention can also be applied to a payout mechanism of the borrowed ball.

(Effect of the Invention) Since the present invention is a ball discharging device for a pachinko machine configured as described above, the solenoid that activates the stopping means for stopping or starting the flow of the ball is a latching solenoid. When the power is supplied for a predetermined time in order to slide the plunger to be linked, the power supply time is shortened because the plunger is held at the position after the sliding after the predetermined time has elapsed and the power supply is completed. Power consumption can be reduced. Furthermore, when a pulse current is used, the power consumption can be further reduced, and the response speed of the solenoid can be increased, so that a desired number of balls can be accurately discharged.
