[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a ball launcher for a pachinko machine that sends a pachinko ball to be fired next to a launch position by a ball delivery member every time the pachinko ball sent to the launch position is launched by a ball launching member.
[0002]
[Prior art]
In a conventional general pachinko machine, every time a pachinko ball is launched by a launcher, the next pachinko ball to be fired is supplied to a launch position of the launcher by a rectifier. However, if a rectifier is provided separately from the launcher, the number of parts to be assembled and adjustment points of the pachinko machine will increase, and the assembly work will take time.
[0003]
Therefore, in the ball launcher of the pachinko machine shown in Japanese Utility Model Publication No. 59-6868, as shown in FIG. 6, the hitting ball 2 for launching the pachinko ball received by the launch pad 1 and the pachinko ball to be fired next are launched. The ball delivery piece part 3 delivered to the position is integrated. In this configuration, as shown by a two-dot chain line in FIG. 6, when the hitting ball 2 is in the initial position, the ball delivery piece 3 blocks the ball supply port 4 so that the pachinko ball does not fall from the ball supply port 4. To. Then, as shown by the solid line in FIG. 6, when the hitting ball 2 is rotated in the firing direction, the pachinko ball on the launch pad 1 is shot with the hitting ball 2, and the ball sending piece 3 is connected to the ball supply port 4. Is opened and only one pachinko ball is received in the launch standby section 5. Thereafter, when the hitting ball 2 returns to the initial position, the pachinko ball received by the launch standby unit 5 is pushed out by the ball delivery piece 3 and dropped onto the launch pad 1.
[0004]
[Problems to be solved by the invention]
However, in the ball launching device of the above publication, when launching the pachinko ball with the hitting ball 2, the ball delivery piece 3 that supports and supports the load of the pachinko ball so that the pachinko ball does not fall from the ball supply port 4, It is necessary to rotate integrally with the hitting ball 2. For this reason, there is a drawback that the hitting force of the hitting basket 2 varies due to the influence of the load of the pachinko ball applied to the ball sending piece 3, and the pachinko ball jumps unevenly.
[0005]
The present invention has been made in view of such circumstances, and therefore the object of the present invention is to provide a ball launcher for a pachinko machine capable of stabilizing the launching condition of the pachinko ball while improving the assembly of the ball launcher. To provide an apparatus.
[0006]
In order to achieve the above object, the ball launching device of the pachinko machine according to claim 1 of the present invention is configured such that the launching operation of the launching member and the delivery operation of the launching member are interlocked with each other. The ball launching member operates alone until the pachinko ball at the launch position is launched by the launching operation of the ball launching member, and immediately after the pachinko ball is launched. The ball delivery member is configured to start the delivery operation in conjunction with each other . The ball launching member and the ball delivery member are engaged with a cam groove provided on one of them so that an engagement pin provided on the other can be relatively moved. In this way, the ball delivery member is configured to perform a delivery operation in an operation pattern corresponding to the shape of the cam groove when the ball launching member is launched .
[0007]
In this configuration, since the ball launching member operates independently until the ball launching member launches the pachinko ball, even if the pachinko ball load is applied to the ball delivery member, the ball launching is not affected. The member can be operated smoothly, and a pachinko ball can be launched with a stable hitting force. Moreover, since the ball launching member and the ball delivery member are unitized, it is possible to reduce the number of parts and adjustment points when the ball launching device is assembled to the pachinko machine.
[0009]
Further, in the present invention, the ball launching member and the ball delivery member are connected to a cam groove provided on one of them by engaging an engagement pin provided on the other side so as to be capable of relative movement. Since the ball delivery member is configured to perform a delivery operation in an operation pattern according to the shape of the cam groove during operation, the cam groove and the engagement pin can be easily engaged without providing a complicated link mechanism. With the configuration, the ball delivery member can be sent out in a predetermined operation pattern.

It slides between a ball removal position (see FIG. 4) for guiding the ball.
[0030]
As shown in FIG. 1, the ball launching device 14 configured as described above switches the first ball removing member 42, the second ball removing member 23, and the guide wall 43 to the normal positions as shown in FIG. deep. As a result, the pachinko balls supplied to the ball supply path 20 are allowed to flow down to the ball delivery cam 24, and the pachinko balls delivered from the ball delivery cam 24 can be received at the launch position.
[0031]
When the firing operation handle 16 is fired, energization / disconnection of the rotary solenoid 32 is repeated at a voltage corresponding to the operation amount. As a result, as shown in FIGS. 3A to 3D, the ball launching rotor 25 rotates from the initial position in the firing direction (the direction in which the hitting ball 27 moves to the right) and is received at the firing position. After hitting the pachinko ball with the hitting ball 27, the launching operation is repeated to rotate in the reverse direction and return to the initial position.
[0032]
At this time, the ball delivery cam 24 performs a delivery operation in the following operation pattern.
During the period in which the ball launching rotor 25 rotates from the initial position [see FIG. 3A] to the vicinity of the hitting position [see FIG. 3B], the engagement pin 40 is positioned in the first groove 39a of the cam groove 39. is doing. Since the first groove 39a is formed to extend in an arc shape in the rotation direction of the ball launching rotor 25, during this period, the cam groove 39 (first groove 39a) accompanies the rotation of the ball launching rotor 25. Does not move, and the ball delivery cam 24 does not rotate. Thereby, the pachinko ball at the outlet of the ball supply path 20 is maintained in a state of being received by the ball stopper 30 of the ball delivery cam 24.
[0033]
Thereafter, during a period in which the ball launching rotor 25 rotates from the vicinity of the hitting position [see FIG. 3B] to a predetermined position (a rotation position slightly before the maximum rotation position), the engagement pin 40 is in the second groove portion. 39b. Since the second groove portion 39b is formed so as to extend obliquely toward the outer peripheral side of the ball launching rotor 25, during this period, the cam groove 39 (second groove portion 39b) accompanies the rotation of the ball launching rotor 25. ) Rotates, the engaging pin 40 moves upward along the second groove 39b. As a result, the ball delivery cam 24 rotates upward with the support shaft 29 as a fulcrum, and the ball stopper 30 moves upward from the outlet of the ball supply path 20. It moves to the ball | bowl receiving position which opposes 20 exit parts, and accepts only one pachinko ball of the exit part of the sphere supply path 20 in the recessed part 31.
[0034]
Thereafter, a period during which the ball launching rotor 25 rotates from the predetermined position to the maximum rotation position [see FIG. 3C], and a period during which the ball rotation rotor rotates in the reverse direction from the maximum rotation position and returns to the predetermined position, The engaging pin 40 is located in the third groove 39c. Since the third groove portion 39c is formed to extend in an arc shape in the rotation direction of the ball launching rotor 25, the cam groove 39 (third groove portion 39c) is accompanied by the rotation of the ball launching rotor 25 during this period. The engagement pin 40 does not move even if the rotation is performed. Thereby, the ball delivery cam 24 stops at the ball receiving position where the concave portion 31 faces the outlet portion of the ball supply path 20, and reliably receives the pachinko ball into the concave portion 31.
[0035]
Further, during the period in which the ball launching rotor 25 returns from the predetermined position to the vicinity of the hitting position [see FIG. 3 (d)], the engaging pin 40 is located in the second groove 39b. When the cam groove 39 (second groove portion 39b) rotates with the movement, the engagement pin 40 moves downward along the second groove portion 39b. Thereby, the ball delivery cam 24 rotates downward from the ball receiving position and returns to the initial position, and fires the pachinko ball in the recess 31 while receiving the pachinko ball at the outlet of the ball supply path 20 by the ball stopper 30. Send to position.
[0036]
After that, during the period in which the ball launching rotor 25 returns from the vicinity of the hitting position to the initial position, the engaging pin 40 is located in the first groove 39a, so the ball delivery cam 24 stops at the initial position and supplies the ball. The pachinko ball at the exit of the path 20 is maintained in a state of being received by the ball stopper 30.
[0037]
As described above, the period from the launching operation of the ball launching rotor 25 to the launching of the pachinko ball is performed immediately after the launching of the pachinko ball by operating the ball launching rotor 25 alone. In conjunction with the operation, the delivery operation of the ball delivery cam 24 is started, the ball delivery cam 24 is rotated from the initial position to the ball receiving position, temporarily stopped there, and then returned to the initial position. Thus, every time the pachinko ball received at the launch position is launched by the ball launch rotor 25, the pachinko ball supplied from the ball supply path 20 is sent out to the launch position by the ball delivery cam 24.
[0038]
On the other hand, when pachinko balls remaining in the ball supply path 20 and the firing position are removed, as shown in FIG. 4, the first and second ball removal members 42, 23 and the guide wall 43 are moved to the right. It slides in the direction to switch to the ball removal position, opens the lower surface (ball discharge port) near the exit of the ball supply path 20, and opens the ball discharge passage 41 provided near the launch position (ball discharge port). Open. Thereby, the pachinko balls remaining in the ball supply path 20 pass through the side of the ball delivery cam 24 and the firing position, fall into the ball removal passage 41, and are extracted outside the machine.
[0039]
