Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pachinko ball discharging device suitable for, for example, a ball lending machine or a prize ball discharging device.

[0002]

2. Description of the Related Art As an example of a pachinko ball discharging device of this type, there is a structure described in Japanese Patent Laid-Open No. 3-111071. In this configuration, the ball supply path for supplying the pachinko balls from the ball tank is provided so as to extend in the vertical direction,
A sprocket (ball receiving member) having a protruding tooth portion is rotatably provided in the middle of the sphere supply path, and further, a solenoid for allowing and blocking the rotation of the sprocket is provided.
With this configuration, when the rotation of the sprocket is allowed, the pachinko ball spontaneously falls from the top to the bottom in the ball supply path and is discharged, while when the rotation of the sprocket is blocked by the solenoid, the pachinko ball is released. The falling of the ball is stopped by the teeth of the sprocket, and the pachinko ball ejection is stopped.

[0003]

However, in the above-mentioned conventional structure, the pachinko ball naturally falls and hits the tooth portion of the sprocket, so that the tooth portion may be chipped due to the load of the pachinko ball. For this reason, the sprocket must be formed of a material having high durability and strength, and there is a drawback that the manufacturing cost becomes high.

On the other hand, as another example of the pachinko ball discharging device, there is a structure described in Japanese Utility Model Laid-Open No. 5-11984. In this configuration, the ball receiving recess (between the tooth portions) of the sprocket is configured to receive the pachinko ball above the rotation axis of the sprocket, and the stepping motor rotationally drives the sprocket. Therefore, the pachinko balls are ejected. In the case of this configuration, since the tooth portion does not receive the load of the pachinko ball, it is not necessary to increase the durability and strength of the sprocket so much, and the manufacturing cost of the sprocket itself can be reduced. However, in the above-mentioned configuration, since the load of a large number of pachinko balls, that is, a large force acts on the rotation shaft of the sprocket, there is a problem that the stepping motor must output a large turning torque when the pachinko balls are discharged. is there. Therefore, it is necessary to take measures such as increasing the size of the stepping motor or providing a speed reducer, which increases the manufacturing cost of the entire structure.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a pachinko ball ejecting apparatus which can reduce the material cost of the ball receiving member and can downsize the driving device such as a motor, thereby reducing the manufacturing cost of the entire structure. To provide.

[0006]

SUMMARY OF THE INVENTION A pachinko ball discharging device of the present invention includes a first ball receiving member which is provided so as to be rotatable in a horizontal direction and has two ball receiving concave portions which are evenly formed on an outer peripheral portion. A second ball having two ball receiving recesses provided on the lower portion of the first ball receiving member so as to integrally rotate in a state in which the rotational phase is deviated by 90 degrees, and having two evenly formed ball receiving recesses A first pachinko ball provided from a ball supply source for supplying the pachinko balls from the ball supply source to the ball receiving concave portions of the first and second ball receiving members, respectively, from the outer peripheral side;
And a second sphere supply path, and the first and second sphere receiving members are rotationally driven by 90 degrees, so that the pachinko spheres alternate from the respective sphere receiving recesses of the first and second sphere receiving members. A motor for ejecting each of the
And a rotation sensor for detecting the rotation angle of the second ball receiving member, and the pachinko balls discharged to the outer peripheral side from the ball receiving recesses of the first and second ball receiving members, respectively. It is provided with first and second ball discharge paths for guiding to the side.

In this structure, when the pachinko balls from the first and second ball supply paths come into contact with the shapes of the outer peripheral surface portions of the first and second ball receiving members, It is also preferable that the load is formed so as to act as a rotational force for rotating the first and second ball receiving members in the forward rotation direction.

A second guide that guides the lower cover member that covers the lower side of the second ball receiving member such that the pachinko ball is smoothly discharged from the ball receiving recess of the second ball receiving member. Providing a convex portion is an even more preferable configuration.

[0009]

According to the above-mentioned means, the first ball receiving member and the second ball receiving member having the two ball receiving concave portions formed evenly on the outer peripheral portion are integrated in a state in which the rotational phases are deviated by 90 degrees. So as to rotate in the horizontal direction, so that the pachinko balls are supplied to the respective ball receiving recesses of the first and second ball receiving members from the outer peripheral side by the first and second ball supply paths, respectively, and By rotating and driving the first and second ball receiving members by 90 degrees by the motor, one pachinko ball is alternately ejected to the outer peripheral side from each ball receiving concave portion of the first and second ball receiving members. It was configured to do. As a result, the force acting on the rotation shafts of the first and second ball receiving members can be significantly reduced, so that the rotation torque of the motor can be reduced, and therefore, the reduction gear transmission is not used. A small motor can be used. In addition, since it is not necessary to form a tooth portion on which each pachinko ball that naturally falls hits each ball receiving member, it is not necessary to increase durability and strength of each ball receiving member so much.

In the case of this construction, the shapes of the outer peripheral surface portions of the first and second ball receiving members are set so that when the pachinko balls abut from the first and second ball supply passages, the load of the pachinko balls is increased. Is formed so as to act as a rotational force for rotating the first and second ball receiving members in the forward rotation direction, the rotational torque of the motor can be further reduced, and a smaller motor can be used.

On the other hand, a first guide convex portion which guides the upper cover member covering the upper side of the first ball receiving member so that the pachinko ball from the ball receiving concave portion of the first ball receiving member is smoothly discharged. And a second guide convex portion that guides the pachinko ball so that the pachinko ball is smoothly discharged from the ball receiving concave portion of the second ball receiving member on the lower cover member that covers the lower side of the second ball receiving member. If it is configured to be provided, the pachinko balls can be reliably discharged from the first and second ball receiving members, and the reliability of the discharging operation can be made extremely high.

It is a motor that can be driven to rotate by degrees. Here, a disc 18 is attached and fixed to the upper end portion of the rotation shaft 13 of the rotation member 12, and 4 is attached to the outer peripheral edge portion of the disc 18.
The individual slits 18a (see FIG. 8) are formed at equal intervals (at intervals of 90 degrees). Then, as shown in FIG. 5, an optical sensor 19 is arranged at the right end of the disc 18 so as to sandwich the outer peripheral edge thereof. This optical sensor 19
Is composed of, for example, a photo interrupter, and is configured to output a detection signal when the slit 18a of the disc 18 is detected. When the detection signal is output from the optical sensor 19, the stepping motor 1
The rotation member 12 can be rotated by 90 degrees if the rotation member 7 is rotated so that the rotation member 12 is stopped. In this case, the optical sensor 19 constitutes a rotation sensor.

On the other hand, as shown in FIG. 5, the first ball discharge passage 20 is provided on the left and right sides of the lower half of the case 9.
Also, the second ball discharge path 21 is provided so as to extend in the vertical direction. Of these, the upper end opening 20a of the first ball discharge path 20 is laterally oriented (rightward in FIGS. 5 and 6) so as to face the outer peripheral portion of the upper sprocket 14 of the rotating member 12, as shown in FIG. And is configured to receive the pachinko ball 2 discharged from the ball receiving recess 14a of the upper sprocket 14.

0b, 11b and the upper end openings 20a, 21a of the ball discharge paths 20, 21 are surrounded by the cylindrical member 22. Further, as shown in FIG. 5, the upper side of the upper sprocket 14 is covered with the upper cover member 23, and the lower side of the lower sprocket 16 is covered with the lower cover member 24.

Here, on the lower surface of the upper cover member 23,
For example, a guide protrusion 25 forming a ridge is provided so as to protrude downward as shown in FIGS. 5 and 6. In this case, when the pachinko ball 2 is ejected from the ball receiving recess 14a while the upper sprocket 14 is rotated, the pachinko ball 2 hits the guide protrusion 25 so that the pachinko ball 2 is reliably guided to the outside, that is, the ejection side. As a result, the pachinko ball 2 is smoothly discharged. Similarly, on the upper surface portion of the lower cover member 24, for example, a guide convex portion 26 forming a ridge is provided so as to protrude upward as shown in FIGS. 5 and 6. Also in this case, when the pachinko ball 2 is ejected from the ball receiving recess 16a while the lower sprocket 16 is rotated, the pachinko ball 2 hits the guide protrusion 26 so that the pachinko ball 2 is reliably directed to the outer side, that is, the ejection side. As a result, the pachinko ball 2 is smoothly discharged.

On the other hand, in FIG. 9 showing the electrical configuration, the control circuit 27 is configured to include a microcomputer and has a control program for controlling the overall operation of the pachinko machine and the operation of the prize ball discharging device 7. ing. The control circuit 27 detects a prize from a prize detecting circuit 28 that detects that the pachinko ball 2 has won a prize opening (not shown).
It is configured to receive a detection signal from the optical sensor 19 and a switch signal from a firing switch 29 which is turned on and off by a firing handle operated by a player. Further, the control circuit 27 drives and controls the stepping motor 17 via a drive circuit 30, and also controls the pachinko ball 2
Is configured to drive and control a firing motor 31 for firing (launching) toward a game section of a game board (not shown) via a drive circuit 32.

Next, the operation of the above configuration will be described. When the prize ball discharging device 7 does not discharge the pachinko balls 2,
The rotating member 12 is stopped, for example, at the position shown in FIG.
In this case, the upper sprocket 14 has one ball receiving recess 1
4a contains a pachinko ball 2 and the other ball receiving recess 1
There is no pachinko ball 2 in 4a. And the first
The pachinko ball 2 from the ball supply path 10 comes into contact with the outer peripheral surface of the protruding portion 14b of the upper sprocket 14. Further, the lower sprocket 16 is in a state where the pachinko ball 2 from the second ball supply passage 11 is supplied by being entered into one of the ball receiving recesses 16a, and the pachinko ball 2 is moved from the other ball receiving recess 16a. The discharged state, that is, the other ball receiving recess 16a
There is no pachinko ball 2 inside. At this time, the pachinko balls 2 are stored in the first ball supply path 10 and the second ball supply path 11 side by side in the vertical direction without a gap.

In the above state, when the pachinko ball 2 hit into the game section wins a prize, the prize ball ejecting device 7 controls to eject, for example, 15 pachinko balls 2 as prize balls. Specifically, the stepping motor 17 is electrically driven to rotate the rotating member 12 in the direction of arrow A in FIG. 6 by 90 degrees. As a result, the upper sprocket 14 is rotated by 90 degrees, and the ball receiving concave portion 14a containing the pachinko ball 2 is rotated to a position corresponding to the upper opening 20a of the first ball discharging path 20, and The pachinko balls 2 are discharged into the first ball discharging passage 20 from the ball receiving recess 14a. At this time, the pachinko ball 2 is guided by the guide convex portion 25 of the upper cover member 23 and is reliably discharged.
At the same time, the ball receiving concave portion 14a of the upper sprocket 14 that does not contain the pachinko ball 2 comes to correspond to the lower opening 10b of the first ball supply path 10, and thus the first ball supply path 10 The pachinko ball 2 is supplied to and stored in the ball receiving recess 14a.

At this time, the lower sprocket 16 also rotates 90 degrees, but the ball receiving recess 16a containing the pachinko ball 2 rotates to a position corresponding to the upper opening 21a of the second ball discharging passage 21. Therefore, the pachinko ball 2 remains stored (held) in the ball receiving recess 16a. At this time, the pachinko ball 2 from the second ball supply path 11 comes into contact with the outer peripheral surface of the protruding portion 16b of the lower sprocket 16. Therefore, from the state shown in FIG.
Is rotated 90 degrees, one pachinko ball 2 is ejected.

Then, in the above state (the state where the one pachinko ball 2 is ejected), the stepping motor 17 is energized to rotate the rotating member 12 by 90 degrees.
The lower sprocket 16 rotates 90 degrees and the ball receiving recess 16a containing the pachinko ball 2 comes to correspond to the upper opening 21a of the second ball discharging passage 21, so that the ball receiving recess 16a moves from the ball receiving recess 16a. 2 is discharged into the second ball discharge passage 21. At this time, the guide protrusion 26 of the lower cover member 24
Thus, the pachinko ball 2 is guided and reliably discharged. At the same time, the ball receiving recess 16 of the lower sprocket 16 that does not contain the pachinko ball 2
a corresponds to the lower opening 11b of the second ball supply path 11, and thus the pachinko ball 2 is supplied from the second ball supply path 11 and stored in the ball receiving recess 16a.

At this time, the upper sprocket 14
Also rotates 90 degrees, but since the ball receiving recess 14a containing the pachinko ball 2 does not correspond to the upper opening 20a of the first ball discharging passage 20, the pachinko ball 2 is stored (reserved) in the ball receiving recess 14a. ) It has been kept. Then, at this time, the pachinko ball 2 from the first ball supply path 10 is moved to the upper sprocket 1
4 to come into contact with the outer peripheral surface of the protruding portion 14b. Therefore, when the rotating member 12 is rotated 90 degrees from the above state, one pachinko ball 2 is ejected. Less than,
Every time the rotating member 12 is rotated 90 degrees, the above-described discharging operation is repeatedly performed, and the pachinko balls 2 are alternately discharged from the upper sprocket 14 and the lower sprocket 16 one by one. Therefore, when the rotating member 12 is rotated 90 degrees by 15 times, 15 pachinko balls 2 are ejected. When performing control to rotate the rotating member 12 by 90 degrees, when the slit 18a of the disk 18 is detected by the optical sensor 19, the rotation of the stepping motor 17 is stopped based on the detection signal. Is configured.

According to this embodiment having such a structure, the upper sprocket 14 and the lower sprocket 16 (rotating member 12) are provided so as to integrally rotate in the horizontal direction in a state in which the rotational phases are deviated by 90 degrees. , First and second sphere supply path 1
0 and 11 are used to supply the pachinko ball 2 to the ball receiving recesses 14a and 16a of the upper sprocket 14 and the lower sprocket 16, respectively, from the outer peripheral side, and the stepping motor 17 is used to supply the upper sprocket 14 and the lower sprocket 16 (rotation). By rotating the moving member 12) 90 degrees at a time, the pachinko balls 2 are alternately ejected one by one from the ball receiving recesses 14a, 16a of the upper sprocket 14 and the lower sprocket 16 to the outer peripheral side. As a result, in the above-described embodiment, the pachinko ball 2 from the first and second ball supply passages 10 and 11 moves the ball receiving recesses 14a of the upper sprocket 14 and the lower sprocket 16 respectively.
16a from the outer peripheral side, and the protrusions 14b, 1 of the upper sprocket 14 and the lower sprocket 16 are
Since the outer peripheral surface of 6b is abutted from the outer peripheral side, the force acting on the rotating shaft 13 of the upper sprocket 14 and the lower sprocket 16 (rotating member 12) can be significantly reduced. Therefore, the turning torque of the stepping motor 17 can be reduced, a small stepping motor can be used without using a reduction gear, the manufacturing cost can be reduced, and the overall configuration can be downsized. can do.

Further, in the above-described embodiment, unlike the conventional structure, it is not necessary to form the teeth on the upper sprocket 14 and the lower sprocket 16 against which the pachinko balls that have naturally fallen, so the upper sprocket 14 and the lower sprocket 16 are not required. It is not necessary to increase the durability and strength of the (rotating member 12) so much, and the manufacturing cost can be reduced.

Further, in the case of the above-mentioned embodiment, the shapes of the outer peripheral surface portions of the upper sprocket 14 and the lower sprocket 16 are changed when the pachinko balls 2 from the first and second ball supply paths 10 and 11 come into contact with each other. The load of the pachinko ball 2 is configured to act as a rotational force that rotates the upper sprocket 14 and the lower sprocket 16 in the forward rotation direction. Specifically, as shown in FIG. 6, the shape of the outer peripheral surface of each of the protrusions 14b and 16b of the upper sprocket 14 and the lower sprocket 16 is the curvature of the outer peripheral surface 14c of the tip side half in the rotational direction indicated by arrow A. Since the radius R1 is configured to be larger than the radius of curvature R2 of the outer peripheral surface portion 14d of the base end side half portion in the rotation direction, the turning torque of the stepping motor 17 can be further reduced, and a smaller motor can be obtained. Can be used.

On the other hand, in the above embodiment, the upper cover member 23 that covers the upper side of the upper sprocket 14 is guided by the first guide protrusion that guides the pachinko ball 2 smoothly from the ball receiving recess 14a of the upper sprocket 14. A second guide protrusion 26 is provided on the lower cover member 24 that covers the lower side of the lower sprocket 16 and that guides the pachinko ball 2 so that the pachinko ball 2 is smoothly discharged from the ball receiving recess 16a of the lower sprocket 16. Since the configuration is provided, the pachinko ball 2 can be reliably discharged from the upper sprocket 14 and the lower sprocket 16, and the reliability of the operation can be made extremely high.

In the above embodiment, the guide protrusions 25, 2
6 is provided on the upper cover member 23 and the lower cover member 24, respectively, but the present invention is not limited to this. For example, the upper sprocket 14 and the lower sprocket 16

Also, since the pachinko balls are alternately discharged one by one from the respective ball receiving concave portions of the second ball receiving member to the outer peripheral side,
The force acting on the rotating shafts of the first and second ball receiving members can be significantly reduced, and a small motor having a small rotating torque can be used without using a reduction gear.
It has an excellent effect that the cost can be reduced and the configuration can be downsized.

Further, in this structure, each ball receiving member has
Since it is not necessary to form a tooth portion against which a pachinko ball that naturally falls hits, it is not necessary to increase the durability and strength of each ball receiving member so much, and the manufacturing cost of each ball receiving member can be reduced. In the case of the above configuration, when the pachinko balls from the first and second ball supply paths come into contact with the shapes of the outer peripheral surface portions of the first and second ball receiving members, the load of the pachinko balls becomes first. Since the first and second ball receiving members are formed so as to act as a rotational force for rotating in the forward rotation direction, the rotational torque of the motor can be further reduced, and a smaller motor can be used. .

On the other hand, on the upper cover member that covers the upper side of the first ball receiving member, there is provided a first guide convex portion that guides the pachinko ball so that it is smoothly discharged from the ball receiving concave portion of the first ball receiving member. A second guide protrusion that guides the pachinko ball so that the pachinko ball is smoothly discharged from the ball receiving recess of the second ball receiving member is provided on the lower cover member that covers the lower side of the second ball receiving member. Since it is configured, the pachinko balls can be reliably discharged from the first and second ball receiving members, and the reliability of the operation can be made extremely high.
