A spilled ball collecting gutter 30 is provided at one end of the spilled ball collecting gutter 30 so as to be located above the foul ball collecting path 3 on the lower surface of the guide rail 2 when the opening/closing panel 9 is closed. A foul ball block portion 32 is integrally provided. When the force of the returning ball is strong, the ball collides with the foul ball block part 32 and falls into the foul ball recovery path 3.

A ball feeding member 33 is rotatably provided at the lower end of the ball supply path 28 so as to be located between the upper ball passage piece 18 and the lower ball passage piece 23. As shown in FIG. 6, this ball feeding member 33 has a ball receiving portion 34 having a substantially U-shaped cross section at one end, and a shaft hole 35 formed at the other end. A magnet piece 36 is attached. Further, the tip of the upper surface of the ball receiving portion 34 is an inclined surface 37. The main body 14 has a rotating shaft 38 erected thereon, which is inserted into the shaft hole 35 of the ball feeding member 33 , and a boss portion 39 is provided at a position facing the rotating shaft 38 of the cover member 15 . Further, an electromagnet 40 is attached to the side of the rotation shaft 38 of the main body 14. Then, with the cover member 15 removed, the rotation shaft 38 is inserted into the shaft hole 35 of the ball feeding member 33,
When the cover member 15 is attached to the main body 14, the tip of the rotating shaft 38 fits into the boss portion 39, and the ball feeding member 33 can be attached to the batted ball supply frame 11.

The magnet piece 36 and the electromagnet 40 are normally demagnetized, and when the magnet piece 36 is attracted to the iron core 41 of the electromagnet 40 and the electromagnet 40 is energized, the magnet piece 36 and the electromagnet 40 are They are designed to repel each other. Therefore, the ball feeding member 33 is always rotated downward by its own weight and the force of the magnet piece 36 being attracted to the iron core 41 of the electromagnet 40. In this state, the lower surface of the ball receiver 34 rests on the lower ball passage piece 23, the ball receiver 34 faces the ball outlet 21, and the tip of the upper surface of the ball receiver 34 is positioned within the batted ball supply path 28. to prevent the ball from falling (

In this state, the upper surface of the ball receiver 34 is in contact with the upper ball passage piece 18, the ball receiver 34 is located within the batted ball supply path 28, and one ball is taken into the ball receiver 34 (see FIG. ).

When the electromagnet 40 is demagnetized again, the ball feeding member 33 is rotated downward by its own weight and the force of the magnet piece 36 being attracted to the iron core 41 of the electromagnet 40, and is held in the ball receiving part 34. The ball is sent from the ball outlet 21 to the ball launcher 2.
Supply to 0. By repeating the above-described operations, one ball in the ball supply path 28 can be supplied to the ball launcher 20. In addition, since the tip of the upper surface of the ball receiving part 34 is an inclined surface 37, when taking the ball into the ball receiving part 34, the force for rotating the ball feeding member 33 can be reduced. The feeding operation can be made smooth.

The ball feeding operation described above is performed by the ball feeding sensor 42.
This is done based on the output of A ball firing mechanism 43 having a ball feed sensor 42 is shown in FIG. The ball launch mechanism 43 is
A firing rod driving member 45 is rotatably attached to the mounting panel 44 by a shaft 46, and a firing rod 47 is attached to the shaft 46. The firing rod driving member 45 obtains the firing force of the firing rod 47 by the biasing force of the spring 48. A gear 49 is provided on the outer periphery of the firing rod drive member 45, and a firing force adjusting member 50 is engaged with the gear 49. When the firing force adjusting member 50 is rotated, the firing rod driving member 45 is also rotated, and the repulsive force of the spring 48 can be adjusted to adjust the firing force. Further, the firing rod driving member 45 is provided with a driving crank 51, and the driving crank 51 is connected to the rotating shaft 5 of the motor 52.
The cam 54 attached to 3 is facing. Further, within the rotation range of the cam 54, a ball feed sensor 42 is provided. As the motor 52 rotates, the cam 54 rotates and drives the firing rod drive member 45 to perform a ball firing operation.
Every time the cam 54 is detected by the ball feed sensor 42, a ball feed signal is transmitted. Therefore, one ball sending signal is transmitted for each ball firing operation.

The signal from the ball feed sensor 42 is transmitted to the ball feed control means 55, as shown in FIG.
A 2s drive signal is sent to the electromagnet 40, and the electromagnet 40 is set to 0.
．． Energize for 2 seconds. A timing chart showing the relationship between the ball feeding signal from the ball feeding sensor 42 and the drive of the electromagnet 40 is shown in FIG.

The ball feeding sensor is not limited to the one described above, and any sensor may be used as long as it can feed the ball in synchronization with the timing of the ball firing operation. Good too.

[0017]

As described above, in the present invention, a foul ball blocking portion is provided in the ball feeding frame of the ball feeding device provided on the opening/closing panel. Therefore, there is no need to form the block piece separately and attach it to the lower surface of the guide rail, reducing the number of parts and simplifying the work process. In addition, since the foul ball block part is provided in a separate position from the guide rail, when the opening/closing panel is opened, there is no extra protruding part near the guide rail, etc., making it easy to clean the guide rail and launch gutter. .
