The screen badminton control method implemented through such a system includes a preparation step (S 10), a pre-step (S 20), a firing step (S 30), a post-step (S 40), and a determination step (S 50). , Consisting of a progress step (S 60) and a replenishment step (S 70).

In the preparation step (S 10), the shuttlecock is stacked and stored in the storage unit 210 to sense the height of the stacked shuttlecock. That is, a plurality of shuttlecocks are stacked and stored so that the cock portion is exposed at the bottom, and sequentially supplied to a plurality of storage units 210 arranged at regular intervals along a cylindrical circumference to store a large number of shuttlecocks. At this time, the number of shuttlecocks stacked in the storage unit through the sensing means 211 is detected, but specifically, the presence or absence of the shuttlecock protruding to the bottom through the first sensing means 212 and the storage unit through the second sensing means 213. It always detects whether the quantity of my shuttlecock is equal to the set value.

The pre-step (S 20) opens the cover 120 of the through portion 110 formed in the screen portion 100. That is, the cover 120 is opened through the opening / closing means 130 to prepare to launch the shuttlecock.

In the firing step (S 30), the shuttlecock is fired through the through portion 110 to the front of the screen portion 100. This is made through the launching unit 200 and specifically detects and grips the shuttlecock exposed at the bottom of the storage unit, and then moves the supply means 220 and the launching means 230 according to the movement line to control the position of the shuttlecock. 1 is sensed through the measuring means 231, and is supplied to the roller 240.

The first measuring means 231 detects the movement of the shuttlecock at a specific position according to the positional movement of the firing means 230, and enters the supplied shuttlecock between the rollers 240 rotated by the first motor 241 To the front of the screen portion 100 through the through portion 110. At this time, the cock portion of the shuttlecock enters between the rollers 240 located on both sides and prevents damage to the rear cone portion.

2 is a specific flow chart of the launching step according to the present invention, the launching step (S 30) is a direction control step of adjusting the up and down and left and right directions of the shuttlecock fired to the front so that the user can adjust the difficulty level and make a realistic throw. (S 31), and further comprises a speed control step (S 32) for adjusting the speed of the shuttlecock being fired.

The direction adjustment step (S 31) may be subdivided into up and down adjustment step and left and right adjustment step in detail, and the up and down and left and right angles of the shuttlecock which are blown forward by separately performing the up and down adjustment step and the left and right adjustment step in any order. By adjusting the, the game can be performed according to the skills of the beginner, intermediate, and advanced by sending the ball in a selected direction and speed for all areas of the badminton court located in front of the screen unit 100.

At this time, the shuttlecock exposed to the lower portion of the storage unit 210 is sensed by the first sensing means 212 to be gripped by the supply means 220 so that a continuous operation of drawing and supplying the shuttlecock stored in the storage unit 210 is performed. When the shuttlecock is gripped, the firing means 230 is advanced to pull out the shuttlecock while the supply means 220 descends, and when the firing means 230 is detected by the first measuring member 231a, the shuttlecock is retracted. It is dropped to the seating plate 232 of the launching means 230.

Thereafter, the dropped shuttlecock is moved forward, and the shuttlecock is entered into the roller 240 at a position sensed by the second measurement member 231b. After being sensed by the second measuring member 231b, the launching means 230 moves backward and moves back to a position detected by the third measuring member 231c.

According to this operation, as shown in FIG. 7, when the firing means 230 is moved, the supply means 220 may elevate and take out the shuttlecock and fall to the firing means 230. To this end, a guide protrusion 222 formed in the supply means 220 is formed.

In addition, a guide plate 233 having a guide groove 234 into which the guide protrusion 222 is inserted is coupled to the launching means 230 to allow the supply means 220 to move up and down according to the front-rear movement. Accordingly, when the launching means 230 advances, the supply means 220 descends along the guide groove 234 to drop the drawn shuttlecock, and when the launching means 230 reverses, the supply means 220 The shuttlecock stored in the reservoir 210 ascending along the guide groove 234 may be sensed and gripped.

That is, repetitive movements are sequentially performed, and the shuttlecock can be pulled out, and malfunctions can be prevented by detecting the movement of the shuttlecock at a specific position through the first measuring means 231. First, when the launching means 230 is sensed by the third measuring member 231c, the supply means 220 rises to a position capable of detecting the shuttlecock, and senses and grips the shuttlecock.

Thereafter, when the launching means 230 is sensed by the first measuring member 231a, the supply means 220 drops the shuttlecock to the launching means 230 in a state in which the descent is made. When the launch means 230 moves forward, the second measurement member 231b is detected, and the dropped shuttlecock enters the roller unit 240.

Thereafter, the launching means 230 enters the shuttlecock into the roller 240 and retracts until it is detected by the third measuring member 231c.

Through this, the launching means 230 and the supplying means 220 are made in a separate driving method to detect and pull out a shuttlecock by moving along a predetermined path, but are operated by the first measuring means 231. Can move accurately at a specific location.

In the vertical adjustment step, the reference angle is set using the second measuring means 252 coupled to the cam 250 rotated by the second motor 251. While moving the shuttlecock during rotation of the cam 250 at the set reference angle, the roller 240 is vertically adjusted to arbitrarily change the throw angle in the vertical direction.

At this time, as shown in Figure 8 (a), the storage unit 210, the firing means 230, the supply means 220 and the roller 240 in the upper position is disposed so that the cam 250 It is adjusted to the reference angle through the second measuring means 252 coupled to. Preferably, the rear part is configured to be hinge-coupled so that the front part is adjustable up and down by the cam 250.

Thereafter, the roller 240 located at the upper portion is moved up and down by the rotating cam 250 to adjust the angle of the front, and the shuttlecock is sent to the front.

In the left and right adjustment step, the reference angle and the left and right rotation range of the driven gear 260 rotated by the third motor 261 are set using the third measuring means 262. Within the set reference angle and rotation range, while the shuttlecock is moving, the roller 240 is adjusted left and right to arbitrarily change the throw angle in the left and right directions.

That is, as shown in FIG. 8 (b), in a state in which the roller 240 is positioned on the top, the reference angle and rotation range of the driven gear 260 are adjusted. Thereafter, the left and right angles are adjusted by the rotation of the driven gear 260 and the shuttlecock is thrown, but the angle is adjusted within a limited range by the third measuring means 262 to prevent being thrown out of the court.

Here, the upper and lower positions of the cam 250 and the driven gear 260 are mutually changeable, and the storage part 210, the launching means 230, the supplying means 220, and the roller 240 are located at the top. , It is preferable that the left and right and up and down angle can be adjusted individually.

The post-step (S 40) closes the cover of the through portion formed in the screen portion. That is, an image projected from the front to the screen unit 100 is covered with the cover through the opening / closing means so that the image can be smoothly output without being disturbed.

In the determination step (S 50), the shuttlecock contacting the screen unit is detected to determine the result. That is, the location of the shuttlecock in contact with the screen unit 100 is discriminated through the recognition means to determine a situation in which an in, out, or sensed shuttlecock is not detected and thus cannot be hit by the user.

In the proceeding step (S 60), the pre-step (S 20), the firing step (S 30) and the post-step (S 40) are repeated or the score is determined according to the determination result of the determining step (S 50).

That is, if the character of the video content hits the shuttlecock hit by the user in the state in which the determination result of the determination step S 50 is In, the pre-step S 20 and the launch step S 30 and the post-step S 40 are performed. Repeated replays are made, and the score is calculated when the judgment result is out or the user cannot hit the shuttlecock.

In the replenishment step (S 70), when the height of the stacked shuttlecock is less than or equal to the set value, the shuttlecock at the bottom of the front of the screen unit is transferred to the storage unit 210 to be inserted and stacked.

That is, by operating the transfer unit 300, in the situation where the shuttlecock is present in the storage unit, the transfer unit 300 does not operate at all times until the shuttlecock present in the storage unit is equal to or greater than a reference value in a state where the shuttlecock is below a reference value. Operate so that the shuttlecock is stored.

3 is a specific flow chart of the replenishment step according to the present invention, wherein the replenishment step (S 70), the conveying step of transferring the shuttlecock to the front of the screen portion 100 to the rear through the lower portion of the screen portion 100 (S 71), a lifting step (S 72) for transferring the shuttlecock transferred to the rear to the upper side of the storage unit 210, and the alignment transfer to arrange the shuttlecock transferred to the upper side to be stacked on the storage unit 210. It is made in step (S 73). That is, the conveyor 310, the lifter 320, and the alignment means 330 are operated simultaneously or sequentially to collect the shuttlecock.

As mentioned above, as the storage unit 210 is provided in a circular shape, the sensing means senses the shuttlecock existing in the storage unit 210 at a position before supplying the first sensing means 212. If this is not sensed, the storage part 210 is rotated to detect the shuttlecock exposed by rotation, and is configured to be finely adjusted to the correct position at the position of the supply means 20.

In FIGS. 9 and 10, a separate launch angle adjustment unit 500 is installed to adjust the launch angle of the shuttlecock in the up and down direction from the front end of the launch unit 200, that is, in front of the pair of rollers 240. have. The shuttlecock launch angle adjustment unit 500 includes a launch pad 510, a shanghai east means, and a sensing unit 530.

The launch pad 510 has one end coupled to the lower front surface of the roller, and the other end is disposed in a free end state extending to the front surface. At this time, the other end of the launch pad 510 is configured to be able to change the vertical angle by external force.

Specifically, a configuration made of a flexible material in which the position of the other end is displaced by elastic deformation while one end of the launch pad 510 is fixed to the lower front of the roller, and one end is hinged to change the position of the other end by rotation. It can be configured as much as possible.

That is, the vertical angle adjustment of the shuttlecock is to change the angle of the launch pad 510 by elevating the other end of the launch pad 510. In the accompanying drawings, the distance from the center to the outer periphery is driven by the electric motor 550 and rotates. The configuration of raising the other end of the launch pad 510 by using the characteristics of the cam 520 is configured differently.

The sensing unit 530 is mounted directly or adjacent to the vertical driving means to sense the launch angle of the launch pad 510 by the vertical movement means. In the present invention, a sensing unit 530 is installed along a circumferential path spaced a predetermined distance from the center of the cam 520 on one surface of the cam 520 for driving up and down to sense the angle of the launch pad 510. .

Since the cam 520 has a plurality of paths having different distances from the center to the periphery, a plurality of intended lengths are set from the center to the periphery, and light is generated at a circumferential point corresponding to a path corresponding to the intended length. When the sensor 533 is installed, the light sensor 533 detects the light blocking portion 531 at a position where the point reaches the highest point, so that the launch pad 510 can be adjusted to the intended angle.

That is, in the configuration in which the height of the two stages can be adjusted by the cam 520, as shown in FIG. 4, the light blocking unit 531 mounted on one surface of the cam 520 is the first light sensor 533a. The highest point of the cam 520 may be set to the lowest position at the position sensed by, and the highest point of the cam 520 may be set to the highest position at the position sensed by the second optical sensor 533b. have.

On the other hand, the control unit 400 controls the movement of the shanghai means by adjusting the electric motor 550 using the sensed value of the sensing unit 530 set to the position of the cam 520 corresponding to the set launch angle. . That is, the electric motor 550 is driven to rotate the cam 520 to a point corresponding to the set firing angle to stop the electric motor 550 when the sensing unit 530 corresponding to the point is detected, The electric motor 550 is driven to rotate the cam 520 so that the cam 520 is positioned at an angle different from the angle, and when the sensing value of the sensing unit 530 corresponding to the intended angle is sensed, the motor is driven again. The electric motor 550 is controlled by stopping the motor 550.

The mounting bracket 540 is for mounting the firing angle adjustment unit 500 to the launch unit 200, the horizontal plate 541 attached to the bottom surface of the base plate 250, and the horizontal plate 541 To the vertical plate 542 is provided vertically connected to the through-hole 542a through which the axis of rotation of the electric motor 550 passes and a plurality of coupling holes 542b to which the electric motor 550 can be coupled is formed. It is composed.

In addition, the spacer 521 is mounted on the cam 520 to allow the cam 520 to be connected to the rotating shaft of the electric motor 550 and to maintain a gap between the cam 520 and the vertical plate 542. ) May be further provided.

For example, in the launcher 510 and the cam 520, which have been changed to the first step of the low angle and the second step of the high angle, each step is set by using the distance from the center of the cam 520 to the outer periphery. The distance from the center of the cam 520 to the highest point is the relatively shortest length, and step 2 may be determined as the relatively longest length.

In addition, a sensing unit 530 is installed to correspond to each step to sense the position of the cam 520 so that the height of the launch pad 510 is changed by the cam 520. That is, when the light blocking portion 531 is detected by the first light sensor 533a by rotating the cam 520 so that the light blocking portion 531 is disposed on the right side of the center of the cam 520, the controller controls the electric motor The driving of the 550 is stopped so that the cam 520 maintains the lowest angle of the launch pad 510.

When maintaining the lowest firing angle, the shuttlecock transmitted by rotation of the roller is guided at a low angle by being guided by the firing angle along the launch pad 510, and at the height of the rotational speed of the roller while being thrown at that angle. The long and long distances are adjusted accordingly.

In addition, when the light blocking unit 531 is rotated so that the cam 520 is rotated so that the light blocking unit 531 is disposed at the center of the cam 520, the second light sensor 533b detects the light blocking unit 531, and the control unit controls the electric motor. The driving of the 550 is stopped so that the cam 520 maintains the angle of the launch pad 510 the highest.

When maintaining the highest firing angle, the shuttlecock transmitted by rotation of the roller is guided at a high angle by being guided by the firing angle along the launch pad 510, and at the height of the rotational speed of the roller while being thrown at that angle. The long and long distances are adjusted accordingly.

Here, in the present embodiment, two light sensors 533, that is, the first and second light sensors 533a, 533b are disposed 180 ° apart in the circumferential direction with respect to one light blocking portion 531, and the electric motor 550 The angle of the two stages is set to be adjusted by the 180 ° rotation of the cam 520 by, but if it is desired to adjust the angle of three or more stages, the optical sensor along the circumferential direction on one surface of the cam 520 corresponding to each stage ( 533). In this case, the uppermost height of the cam 520 may be determined according to which light sensor 533 is detected by the light blocking unit 531, and through this, it is possible to determine the launch angle of the shuttlecock.

The present invention has been described with reference to the accompanying drawings, with reference to preferred embodiments, but it is apparent to those skilled in the art that various modifications can be made without departing from the scope of the present invention. Accordingly, the scope of the invention should be construed by the claims set forth to cover these many variations.
