It is also possible to continuously fire the ball 12 with the type of ball set at the time.

A control device 47 based on FIGS.
The control by will be specifically described. FIG. 11 is a block for setting the drive command of the inverter motor 32, that is, the number of rotations of the rotary disk 16, FIG. 12 is a graph showing the relationship between the measured flight distance and the theoretical flight distance, and FIG. A graph showing the relationship between the firing speed and the rotation speed of the rotary disk, FIG. 14 is a table for setting the rotation speed of the left and right rotary disks, and FIG. 15 is a flow chart showing the relationship between various processing tasks.

An example of a method for setting the rotation speed of the rotary disk 16 from the distance / angle / curve information input on the operation panel 46 will be described with reference to FIG.

Based on the distance information input on the operation panel 46, the theoretical flight distance L _{T is} calculated according to the map shown in FIG.
Set. As shown in FIG. 12, regarding the relationship between the measured flight distance L and the theoretical flight distance L _T , it has been confirmed that the measured flight distance L becomes shorter due to resistance or the like as the distance becomes longer (for example, the measured flight distance L ₁ The theoretical flight distance L _T becomes shorter at the boundary. Therefore, the theoretical flight distance L _T is set for the input distance (actual flight distance L) based on FIG.

Next, the theoretical firing speed V _T is calculated by the following equation based on the set theoretical flight distance L _T and the input angle. V _T = K ・ (L _T / sin θ ・ cos θ) ^1/2 where L _T is the theoretical flight distance (m) and V _T is the theoretical firing speed (k
m / h), θ is the firing angle (degrees).

Based on the calculated theoretical firing speed V _T ,
The average rotation speed N of the rotary disk 16 is set according to the map shown in FIG. As shown in FIG. 13, it has been confirmed that the theoretical firing rate V _T and the number of revolutions (rotational velocity) of the rotary disk 16 have different functions with the theoretical firing rate being V _P. Therefore, the rotating disk 1 is calculated based on FIG. 13 with respect to the calculated theoretical firing speed V _T.
The average rotation speed N of 6 is set.

Next, based on the set average rotation speed N of the rotating disk 16 and the input curve information of ~, according to the table shown in FIG.
The rotation speeds N _L and N _{R of the above} are calculated. That is, when the left strong curve of is input, the rotation speed of the left rotation disk 16 is set to the average rotation speed N-150 and the right rotation disk 16 is rotated.
Is set to an average rotation speed N + 150, and the rotation speed of the right rotating disk 16 is relatively increased to make a strong left curve.
Similarly, in the case of (1) to (4), the rotational speed of the left and right rotary discs 16 is made different according to the direction and strength of the curve to obtain the desired curved state.

In the above-described embodiment, the description has been given on the condition that a curve is always formed. However, even when the ball 12 can be hit straight, there is a slight difference in the number of rotations of the left and right rotary discs 16. By giving the ball 12 rotation while holding it, it is possible to hit the ball 12 without stalling in the middle, that is, a so-called fork ball state.

In this way, the left and right rotating disks 16
After the rotational speeds N _L and N _{R of the above} are calculated, the frequencies of the left and right inverter motors 32 are calculated by the frequency / rotational speed conversion formula. As a result, the frequencies of the left and right inverter motors 32 are set based on the distance, angle, and curve information input on the operation panel 46.

After the setting of the type of balls is completed, a predetermined number of balls 12 are loaded from the uppermost part of the spiral path 20 of the ball stocker 15 so that the balls 12 can move to the path 2 by their own weight.
Rolls along 0. The lowermost ball 12 is supplied to the ball receiving portion 21, and the remaining balls 12 are retained in the passage 20 and the preparation is completed. When the preparation is completed, the number of the ball type to be fired is displayed by operating the number button (for example, 2), and the ball type feeding is selected (for example, fixed). At this time, the display status of the operation panel 46 is as shown in FIG.

By pressing the confirmation button 55 of the setting confirmation section 54, the ball launching device 11 operates based on the launch specifications of No. 2. That is, the ball launch pad 17 is tilted by driving the tilt motor 25, and the tilt angle is set to 35 degrees. The rotating disk 1 is driven by the inverter motor 32.
6 rotates and is set to a rotation speed at which the ball 12 is launched at a distance of 20 m at an inclination angle of 35 degrees based on the control block shown in FIG. Further, based on the table shown in FIG. 14, the left and right rotating discs 1 are arranged so that the left curve is weak.
6 makes a difference in the number of rotations. When the number of rotations of the ball launch pad 17 and the left and right rotating discs 16 becomes a predetermined state,
The ready lamp 60 lights up.

After the ready lamp 60 is turned on, the launch button 58 is pressed to launch the ball 12.
That is, by driving the geared motor 41, the plate cam 39 is rotated to the pushing position shown by the chain double-dashed line in FIG. 3, and the outer peripheral edge portion 40 causes the ball 12 of the ball receiving portion 21 to rotate in a pair along the ball guide 37. It is extruded between the disks 16. As a result, the ball 12 is sandwiched between the left and right rotary discs 16 that rotate at a predetermined number of rotations, and the ball 12 is shot with a tilt angle of 35 degrees, a distance of 20 m, and a slight left curve.
At this time, the patrol lights P of different colors are sequentially turned on every one second from three seconds before the ball 12 is fired, and the firing timing of the ball 12 is recognized.

When the plate cam 39 is rotated to the position shown by the alternate long and two short dashes line in FIG. 3, the plate cam 39 is interposed between the lowermost portion of the passage 20 and the ball receiving portion 21, and the plate of the plate cam 39 is moved. The surface 42 prevents the ball 12 to be sent next from moving to the ball receiving portion 21. This prevents the balls 12 from being continuously supplied to the ball receiving portion 21. In this way, the pushing operation of the ball 12 by the plate cam 39,
Since it also serves as a stopper for the ball 12 to be supplied next, the mechanism becomes extremely simple and inexpensive.

After the ball 12 is fired, the plate cam 39 is rotated to the standby position by the reverse rotation of the geared motor 41, and the ball 12 at the bottom of the passage 20 rolls down to the ball receiving portion 21 by its own weight. When the standby position detection limit switch 44 detects the rotation of the plate cam 39 to the standby position and the ball detection limit switch 43 detects the supply of a new ball 12 to the ball receiving portion 21, the preparation completion lamp 60 lights up. By pushing the firing button 58 in this state, the ball 12 is fired again with a tilt angle of 35 degrees, a distance of 20 m, and a slightly curved left curve. In the fixed mode, each time the launch button 58 is pressed in the above-described manner, the ball 12 is launched at an inclination angle of 35 degrees, a distance of 20 m, and a slightly curved left curve. For this reason, it becomes possible to carry out repeated practice focused on the purpose such as supplying floating balls to a place waiting for practice such as heading or volley shooting.

Similarly, by selecting the number 1 and the fixed mode (see FIG. 17), each time the firing button 58 is pressed, the ball 12 is fired at an inclination angle of 30 degrees, a distance of 10 m, and a strong left curve. Further, by selecting the number 3 and the fixed mode (see FIG. 19), each time the firing button 58 is pressed, the ball 12 is fired at an inclination angle of 45 degrees, a distance of 40 m, and a slightly curved right curve.

Next, the case where the ball type feeding is set to the automatic mode will be specifically described. A case where the automatic mode is selected by operating the changeover switch 57 of the ball type feeding unit 56 in the state of the operation panel shown in FIG. 19 will be described. in this case,
Each time the firing button 58 is pressed, the balls 12 are fired in the order of the number 1, number 2, and number 3 balls.

When the automatic mode is selected and the setting confirmation section 54 confirmation button 55 is pressed, first, the ball launching device 11 is put into a state of launching the ball 12 with the type of ball set in No. 1.
Is operated. That is, the ball launch pad 17 is tilted by driving the tilt motor 25, and the tilt angle is set to 30 degrees. The rotating disk 1 is driven by the inverter motor 32.
6 is rotated, and the ball 12 is set to a rotational speed at which the ball 12 is launched at a distance of 10 m with an inclination angle of 30 degrees. Further, the rotational speeds of the left and right rotary disks 16 are made different so that a strong left curve is formed. When the number of rotations of the ball launch pad 17 and the left and right rotary discs 16 reaches the state of the ball type set by the number 1, the preparation completion lamp 60 is turned on. Ready lamp 6
When 0 is turned on and the firing button 58 is pushed, the plate cam 39 is rotated to the pushing position and the ball 12 is pushed between the left and right rotating discs 16. As a result, the ball 12 is launched at a tilt angle of 30 degrees, a distance of 10 m, and a strong left curve.

Next, the ball 1 is selected from the types of balls set in No. 2.
The ball launching device 11 is operated so as to launch 2.
That is, the inclination angle of the ball launch pad 17 is set to 35 degrees, and the rotating disk 16 is set to the ball 12 at an inclination angle of 35 degrees.
Is set to the number of revolutions at which the is fired at a distance of 20 m. Also, the left and right rotating discs 1 so that there is a weak left curve
6 makes a difference in the number of rotations. When the number of revolutions of the ball launch pad 17 and the left and right rotary discs 16 reaches the state of the ball type set by the number 2, the ready lamp 60 is turned on, and the firing button 58 is pressed to move the ball 12 by the plate cam 39. It is pushed out between the left and right rotating disks 16.
As a result, the ball 12 has an inclination angle of 35 degrees and a distance of 20.
m, fired at a slightly left curve.

Next, the ball 1 is selected from the types of balls set in No. 3.
The ball launching device 11 is operated so as to launch 2.
That is, the inclination angle of the ball launching pad 17 is set to 45 degrees, and the rotating disk 16 moves the ball 12 at an inclination angle of 45 degrees.
Is set to the number of revolutions at which the is fired at a distance of 40 m. In addition, the left and right rotating discs 1 so that the curve becomes a weak right
6 makes a difference in the number of rotations. When the number of revolutions of the ball launch pad 17 and the left and right rotary discs 16 becomes the state of the ball type set by the number 3, the ready lamp 60 is turned on, and the firing button 58 is pressed, whereby the ball 12 is moved by the plate cam 39. It is pushed out between the left and right rotating disks 16.
As a result, the ball 12 has an inclination angle of 45 degrees and a distance of 40 degrees.
m, fired on a slightly curved curve to the right.

Again, the ball 1 with the type of ball set in No. 1
The ball launching device 11 is operated in a state of launching 2, and thereafter the same operation is repeated to sequentially launch the balls 12 of three types of balls. As described above, when the automatic mode is selected, the balls 12 can be fired in the order of the ball types No. 1 to No. 3 each time the firing button 58 is pressed. Therefore, the balls 12 of different types can be fired to supply the balls 12 in a state corresponding to various situations, and it becomes possible to practice in a state relatively close to the actual battle.

In the above-described embodiment, an example in which three types of balls are set has been described, but in the case of the ball launching device 11 shown in the figure, the types of balls can be set up to 9 types up to number 9. You can set the type of ball. It is also possible to set ten or more types of spheres by changing the display unit, display form, and the like. In addition, three kinds of balls 1
2 is sequentially and repeatedly fired, but it is also possible to repeatedly and repeatedly fire the balls 12 of two kinds of three kinds out of three kinds. It is also possible to sequentially and repeatedly fire the balls 12 of any number of 9 types of balls up to the number 9 (or of 10 or more types of balls).

In the ball launching device 11 described above, a large number of balls 12 can be stored in the ball stocker 15 and the launch button 58 can be pressed to launch the balls 12 by rotating the plate cam 39. Further, since the type of ball is set based on the information on the distance, angle, and curve, it is possible to always shoot the ball 12 with various set types regardless of the launch angle and the like.
Further, since a plurality of types of balls are set and stored and the stored types of balls are selected, the ball 12 can be shot by selecting an arbitrary type of balls according to the usage conditions and the purpose of practice. . In addition, since a memorized sphere type is selected by a fixed mode in which one sphere type is fixedly selected and an automatic mode in which a plurality of sphere types are sequentially and repeatedly selected, various situations are assumed. The ball 12 can be fired in this state.

Further, in the ball launching device 11 described above,
Since the plate cam 39 is rotated by the forward / reverse drive of the geared motor 41 to push the ball 12 between the pair of rotating disks 16, the pushing mechanism of the ball 12 becomes simple and inexpensive, and against the mud and dirt. Does not hinder the operation. Further, since the tilt motor 25 drives the worm speed reducer 26 to tilt the ball launch pad 17, the tilt angle of the ball launch pad 17 can be set inexpensively and accurately. Further, since the ball 12 is always rotated so as to rotate to cause the ball 12 to fire, it is possible to stably fly the ball 12.
