The controller (MPU) controls the overall operation of the practice ball launching device 100, which is roughly divided into manual mode, automatic mode, and image acquisition device mode for operation.

In the case of the manual mode, the controller (MPU) drives the rotation motor 120 and the tilt motor 117 according to the input from the direction setting keys (vertical, horizontal) of the touch screen, and sets the launching direction of the exercise ball launcher 105, According to the firing command from the touch screen, the cylinder 130 of the hydraulic device is operated and the exercise ball is fired through the solenoid valve driving part (SOD). In the case of the automatic mode, the controller (MPU) drives the rotation motor 120 and the tilt motor 117 according to the input from the direction setting keys (vertical, horizontal) of the touch screen, and sets the launching direction of the exercise ball launcher 105, The cylinder 130 of the hydraulic device is operated by the solenoid valve driving part (SOD) and launches the practice ball every set time period (for example, every 15 seconds). In the case of the image capture device mode, the controller (MPU) controls the rotation motor 120 and the tilt motor 117 so that the practice ball launcher 105 faces the player on the field captured by the image capture device 1, 2 (CAM1, CAM2) Then, the operation of the practice ball launching device 100 is controlled so that when the player moves with a predetermined movement (for example, when the player raises his arm upwards), after 1 to 2 seconds, the ball will be fired by electromagnetic force. The valve driving part (SOD) operates the air cylinder 130 of the hydraulic device, and launches the exercise ball.

Fig. 7 is an operation sequence diagram of the practice ball launching device according to the embodiment of the present invention, which is used to explain the operation in the case of manual mode and automatic mode. And, FIG. 8 is an operation sequence diagram of a practice ball launching device according to yet another embodiment of the present invention, which sets the launching direction through the image acquisition devices 1, 2 (CAM1, CAM2) arranged on the side of the main body 102, and through the The image acquisition device 1, 2 (CAM1, CAM2) senses the player's movement and launches a practice ball.

First, with reference to FIGS. 6 and 7 , the operation of the practice ball shooting device 100 shown in FIGS. 1 to 5 will be described.

With regard to the practice ball launching device 100, as described above, the touch screen (TS) is arranged outside the main body 102, the touch screen (TS) is connected to the controller (MPU), and the controller (MPU) is built in Inside the main body 102, a controller (MPU) controls the actions of various operating elements provided inside the main body 102 by using data input through the touch screen (TS). In other words, the controller starts to control the actions of the tilt motor 117 and the swing motor 120 , the hydraulic pump 142 and various solenoid valves 146 , 148 , 150 inside the main body 102 .

The practice ball launching device 100 can be operated in a manual setting mode and a motion sensing mode through the control of the controller (MPU). As far as the manual setting mode is concerned, the user uses the touch screen (TS) arranged on the main body 102 to set the sports mode (penalty kick, corner kick tactics, ground ball shooting, volley ball, header shot, any one or a combination of them) and launch cycle (e.g., launch approximately every 15 seconds), launch practice balls into court 10 each time the launch button is pressed, or select ground corner, volley corner, overhead corner , one or more of the balls or their mixed modes, and press the launch button, the launch angle (tilt and rotation motors 117, 120) of the hollow body 114 is adjusted according to the automatically selected motion mode, and the launch is continuous according to the preset cycle practice ball. At this time, an example in which the launch button is located on the touch panel (TC) has been described, but it can be provided on a remote controller carried by a soccer player using a general remote control device.

[Manual/Automatic Setting Mode of Practice Ball Launching Device 100]

If the practice ball launching device 100 is operated, the launcher (MPU) detects the pressure in the nitrogen tank 144 during S1, and checks whether the piston 132 of the cylinder 130 protrudes (discharges) at the speed set in advance. pressure. If the pressure of the nitrogen pipe in the nitrogen tank 140 cannot reach the pre-set pressure, the controller drives the hydraulic pump 142 after opening the recovery and supply solenoid valves 146 and 148 through the solenoid valve driver (SOD) in the process of S6. Accordingly, the hydraulic pressure in the cylinder 130 is recovered to the hydraulic tank 140 and then supplied to the nitrogen tank 144 . If the hydraulic pressure is continuously supplied to the nitrogen tank 144, the pressure applied to the nitrogen pipe provided inside increases and reaches the set pressure.

In the process of S2, the pressure of the nitrogen tank is determined to be the set pressure, the controller (MPU) closes the recovery and discharge solenoid valves 146, 148, 150 through the solenoid valve driver (SOD) in the process of S3, and in S4 During the process, it is detected whether the launch button of the touch screen or the remote controller is pressed, if it is judged that the launch button is pressed in the process of S4, the controller (MPU) will open the discharge solenoid valve 148 in the process of S5 to set time (T). At this time, the hydraulic pressure filled in the nitrogen tank 144 at high pressure is supplied to the inflow port of the cylinder 130 through the discharge solenoid valve 148 at high speed due to the expansion of the compressed nitrogen pipe.

Thus, the cylinder 130 makes the piston 132 protrude in the forward direction by the hydraulic pressure flowing in at a very high pressure, and the striking plate 134 coupled to the end portion of the cylinder 132 is struck by the protruding forward direction of the piston 132 . A practice ball is placed at the end of the hollow body 114 and fired in a forward direction. At this time, the launch angle of the practice ball launcher 105 located in the space of the main body 102 of the practice ball launcher 100 is determined by the controller controlling the tilt motor 117 and the rotation motor 120 .

After the controller (MPU) executing the S5 process opens and recovers and supplies the solenoid valves 146 and 148 through the solenoid valve driver (SOD) in the S6 process, it drives the hydraulic pump 142 in the S7 process to fill the nitrogen tank 142 with hydraulic pressure. .

If, in the aforementioned S4 process, the launch button displayed on the touch screen (TS) is not selected, then the controller (MPU) exercises the level of the ball launcher 105 hollow body 114 according to the set mode in the S8 process. , the vertical angle and the launch interval are adjusted, the aforementioned S5 process is executed. The mode set in the process of S8 refers to the setting of the automatic emission mode and the image acquisition device mode.

If, in the S8 process, the setting mode is the situation of the automatic launching mode, the controller (MPU) drives the rotation motor 120 and the tilting motor 117 through the input from the direction setting keys (vertical, horizontal) of the touch screen, and sets the exercise The launching direction of the ball launcher 105 operates the cylinder 130 of the hydraulic device through the solenoid valve driving part (SOD) every preset time period, and launches the exercise ball. In addition, when the setting mode is judged to be the image capture device mode in the process of S8, the controller (MPU) controls the operation of the practice ball launching device 100 according to the sequence shown in FIG. 8 , and in the case of the stop mode in the process of S8, Do nothing.

[Mobile Sensing Mode]

As far as the mobile sensing mode is concerned, after the emission direction is set by the image acquisition devices 1, 2 (CAM1, CAM2) arranged on the side of the main body 102, the image acquisition devices 1, 2 (CAM1, CAM2) according to the Or the movement of the player on the side to launch the practice ball.

8, the controller (MPU) checks whether the current mode is the image capture device mode in the process of S104. If the retrieval result is not in the operation mode of the image acquisition device, then skip to the S17 process, and as explained above, launch the practice ball according to the manual/automatic mode operation.

If it is determined in the process of S12 that the image acquisition device is in the operation mode, the controller (MPU) receives the image signals captured by the image acquisition devices 1 and 2 (CAM1, CAM2) installed on the side of the main body 102 in the process of S11, and In the process of S12, the movement of the player located in front of or to the side of the practice ball launching device 100 is detected. After the controller (MPU) that detects the player's movement grasps the detected player's position, in the S13 process, the tilt motor 117 and the horizontal motor 120 are controlled, and the vertical angle and the horizontal angle are adjusted, so as to exercise The launch angle of the ball launcher 105 is set.

Afterwards, the controller (MPU) analyzes the image signals transmitted from the image acquisition devices 1, 2 (CAM1, CAM2) in the process of S14, and analyzes the movement of the subject, and retrieves the movement of the player in the process of S15. Whether it is a preset movement. For example, it is searched whether the player is raising his arm or not. The retrieval can be easily retrieved by comparing the frame image 1 second ago with the current frame image.

In the S15 process, if it is judged that the movement of the player of the image signal received by the image acquisition device 1, 2 (CAM1, CAM2) is a preset movement, then the controller (MPU) will control the electromagnetic valve driver in the S16 process. (SOD) controls, as described above, the hitting plate 134 provided at the front part of the cylinder 130 piston 132 hits the practice ball, so that the practice ball is launched toward the subject.

According to the operation mode of the launch of the practice ball launcher 100, the launch port of the practice ball launcher 105 will face a certain part, and the practice ball launched towards the player will fly to the player's body (for example, feet, hands, etc.) Or roll to the sideline or goal line, and finally fall to the ground of the field.

In the above-described embodiment, a hydraulic cylinder was used as an example for the actuator of the exercise ball launcher 105, but a pneumatic cylinder may be used by those skilled in the art who understand the specification of the present invention.

FIG. 9 is a specific configuration of a ball recoverer according to an embodiment of the present invention, showing the situation that it is installed on one side of the ground of the court 10 . At this time, as described above, the field should be understood as a concept including a soccer field, a basketball field, a volleyball field, and a foot volleyball field where ball games can be played. In order to make the practice ball falling on the field 10 roll from the half-line (or half-line) to the goal line (or end line), it is formed obliquely (θ2) from the center to both sides. As shown in FIG. 3 , the ball retriever 200 shown in FIG. 9 is installed in the transfer trough 14 formed in the rear part of the goal line or the end line of the field 10 .

The transfer chute 14 is formed with an incline downward from one corner to the other corner or the central direction. As a result, practice balls dropped onto the field 10 slanting from the half line (HL) or the half line to the goal lines or end lines on both sides roll toward the goal line from the half line (HL) and finally gather in the transfer chute 14 . The practice balls collected in the transfer chute 14 roll toward the lower end of the ball returner 200 , which is a cylindrical collection pipe, and the practice balls flowing in the lower end direction of the ball returner 200 flow into the lower end gate (G) of the ball returner 200 .

As shown in FIG. 9 , when the recovery motor 206 installed on the upper portion of the ball recovery unit 200 rotates, the rotation shaft 208 connected thereto rotates. At this time, a helical screw 210 having a pitch (eg, 220 mm) wider than the diameter of the practice ball by about 1 cm is formed on the outer peripheral surface of the rotating shaft 208 . At this time, the distance (r1) between the rotating shaft 208 and the inner surface of the ball recoverer 200 is formed to be about 2 mm to 3 mm smaller than the diameter r2 of the practice ball. Thus, when the rotating shaft 208 rotates, the practice balls flowing into the lower end gate G of the ball recoverer 200 are transferred to the upper part along the screw conveyor 212 including the rotating shaft 208 and the helical screw 210 . At this time, the distance (r2) between the rotating shaft 208 and the inner surface of the ball retriever 200 is formed smaller than the diameter (r1) of the practice ball, so that the practice ball is slightly deformed and thus smoothly transferred to the upper part.

The vibrating plate 214 vibrating in the longitudinal direction by the rotation of the vibrating motor 216 is fitted in the transfer groove 14 of the front portion of the door G of the ball retriever 200 . The vibration motor 216 rotates simultaneously with the recovery motor 206 during the ball recovery operation, so that practice balls collected at the end of the downwardly inclined transfer chute 14 smoothly enter the direction of the gate (G) of the ball recovery device 200 .

The practice balls transferred to the upper portion of the screw transfer device 212 of the ball recoverer 200 are discharged to the ball discharge pipe 202 by the rotation of the helical screw 210 . The practice ball discharged through the ball discharge pipe 202 is configured as shown in FIGS.

For example, the following situation can be considered: to the direction of the door where the practice ball rolls into the door from the rotation shaft 208 of the helical screw 210, two poles are vertically erected at a distance 1mm shorter than the diameter r2 of the practice ball. Both sides of the distance of ~ 2 mm. If the exercise ball rolls and flows into the door of the ball retriever constructed according to another embodiment as described above, it is located between the rotating shaft 208 and the two rods. If the helical screw rotates, the exercise ball follows the The rotating shaft and the two rods are moved in the vertical direction to be put through the upper opening of the ball receptacle 104 of the practice ball launching device 100 therein.

In the composition of FIG. 9 as described above, the ball discharge pipe 202 arranged on the upper part of the ball recoverer 200, as shown by "R" in the figure, can be designed as follows: it is arranged in a cylindrical collection in a rotatable form. The upper part of the pipe 204 is rotated manually or automatically by power by rotating a ring gear or the like by a motor.

10 is a detailed configuration diagram of a ball dispenser 300 according to the present invention, which is installed on a post 25 erected vertically on the ground of the court 10, so that the practice ball falls to the court 10, or makes the practice ball fly in the horizontal direction, toward Players located on the court 10 distribute the balls and use them effectively for foot volleyball and volleyball spikes, basketball three-point shots, and the like.

Referring to FIG. 10 , the ball dispenser 300 includes a case 301 coupled to an upper side of the post 250 . The housing 301 is open on one side of the upper portion, and a ball storage 304 is formed inside, and the inside of the ball storage 304 is separated by a partition wall 308 to form a discharge space 306 . The floor 305 of the ball storage 304 is formed to be inclined downward toward the discharge space 306, and an opening is formed on the floor of the discharge space 306, and a discharge pipe 316 for discharging practice balls is rotatably coupled to the opening.

A stopper (stopper) 314 is vertically provided on one side of the discharge opening formed on the lower side of the discharge space 306, and the rotary opening and closing plate 310 is screwed to the rotating shaft of the opening and closing motor 302 at the partition wall 308. The opening and closing motor 302 is fixed on one side of the housing 301 . The rotary opening and closing plate 310 opens and closes the discharge hole formed in the lower part of the partition wall 308 by the rotation of the opening and closing motor 302, and the practice balls stored in the ball storage space 304 are discharged through the discharge hole.

The upper end portion of the discharge pipe 316 is inserted into an installation space provided under the housing 302, and a rack of a linear bevel gear 318 is coupled therearound. The driving gear of the linear bevel gear 318 is combined with the rotating shaft 322 of the swing motor 320 fixed in the installation space, and connected to the opening and closing motor 302 , the swing motor 320 , and the controller (MCU) 324 .

At this time, it is shown that the height of the football goal post 12 is reduced by the light emitting element element arrays XL1-XL4 and the light-receiving element arrays XP1-XP4 arranged on the left and right sides of the ball sensing gate (BSG) in the shape of a rectangular frame ( 2440mm) is divided into 4 equal parts and arranged at intervals of 610mm, and the light-receiving element arrays XP1-XP4, YP1-YP10 arranged on the upper and lower sides of the ball sensing gate (BSG) divide the lateral length of the football goal post 12 (7320mm) is divided into 10 equal parts and set at intervals of every 732mm.

At least three light-emitting elements are arranged at equal intervals inside each of the light-emitting element arrays XL1-XL4, YL1-YL10, and are arranged correspondingly to the light-emitting element element arrays XL1-XL4, YL1-YL10. At least three light-receiving elements are also arranged at equal intervals inside each of the light-receiving element arrays XP1 to XP4 and YP1 to YP10 in opposite directions. The light-emitting element arrays XL1-XL4 and YL1-YL10 configured as above are respectively driven to emit light according to the X-axis and Y-axis driving signals, and the light-receiving element arrays XP1-XP4 and YP1-YP10 perceive the light-emitting element arrays XL1-XL4 , YL1 ~ YL10 light source.

In the above-described embodiment, although it has been described that three elements are arranged inside the light-emitting element arrays XL1-XL4, YL1-YL10 and the light-receiving element arrays XP1-XP4, YP1-YP10, in order to improve the sensitivity, more elements can be arranged. Quantity, it is obvious.

Fig. 14 shows the composition of the scorer (SCNT). The scorer drives the light-emitting element element arrays XL1~XL4, YL1~YL10 of the ball sensor gate (BSG) shown in Fig. 13 to read the light-receiving elements. Arrays XP1-XP4, YP1-YP10 output, sense which part of the goal post 12 the practice ball has passed, convert the score and display it according to the speed of the practice ball sensed by the speed gun (SG).

As a result, practitioners can practice with more interest. As mentioned above, the weighted value means that 1 is given when the speed of the ball is more than a strong shot (speed 60Km/h), and 0.5 is given when it is less than that. Different scores are also different.

If the practice ball shot by the practicer passes through the "A" area and "B" area of the ball sensor gate (BSG) and then scores the goal, the average value of the two areas is determined as the goal post passing score, which is given according to the speed gun. (SG) Perceived speed weighted to display goalpost passing score on display (DISP). In addition, in the state where the practice ball is in the passing area of the ball sensing gate (BSG), the impact sensing sensor (IS) installed on the goal post 12 senses the impact, and the score controller (SCNT) and Regardless of the passing area of the practice ball, the goalpost passing score is displayed as "10" points.

As mentioned above, the football practice device according to the present invention senses the passing area of the goal post and the speed of the ball when the trainer shoots toward the goal post, and displays the passing area of the goal post and the passing score of the goal post on the display. The trainer can practice with more interest, and can easily confirm which area the ball passed through by oneself, so that the shooting posture can be corrected more quickly.

Although not specifically illustrated in the described embodiment, infrared rays or light sensors are arranged at the vertical and horizontal intervals of the ball diameters of the goal post 12, which can perceive the position where the practice ball passes the goal post 12, and pass the goal post according to the practice ball. 12 points are given in different areas, so that the player can confirm the score of the shot by himself. For example, it is possible to display the score by setting 10 points for passing near the four corners of the goalpost 12 and gradually decreasing the score toward the center of the goalpost 12 .
