Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ball collecting apparatus and a method of controlling the ball collecting apparatus,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ball collecting apparatus and a method of controlling the ball collecting apparatus, and more particularly, to a ball collecting apparatus including a pinching prevention member for a soft ball and capable of preventing pin- And a method of controlling the same.

Screen baseball is a sort of virtual baseball that is similar to a real baseball game. More specifically, a pitching machine positioned on the rear side of the screen and a screen on which an image is projected may be used to receive a feeling that the actual ball is pitching while viewing a projected image. In order to hit the pitching ball, So that a feeling of playing in a real baseball stadium can be obtained (see FIG. 1).

In order for the ball to be ejected immediately from the pitching machine in response to a user's ejection signal input in the screen baseball, the ball collected by the ball collecting device must be continuously supplied to the pitching machine via the ball transfer device.

The ball collecting apparatus generally collects the balls scattered in the course of the screen baseball, inserts the balls collected in the inclined space into the groove formed in the rotating plate, and then rotates the rotating plate to move to the ball transporting apparatus .

In this case, a plurality of balls are bundled in a narrow space, and balls are bundled by the weight of the balls, so that a ball may not be inserted into the groove of the turntable.

In this case, since the ball can not be supplied to the ball transporting apparatus, various techniques for solving such problems have been disclosed.

Korean Patent Publication No. 10-1513152 discloses a golf club having a separating step formed on the lower side of the storage part to separate a golf ball accommodated in a receiving groove formed on a rotating plate and a golf ball positioned on an upper side of the golf ball received, And a golf ball.

However, since the golf ball supply device of this type is prevented from being caught by the golf ball only after the golf ball is received in the receiving groove, there is a limitation in that it is not possible to prevent the golf ball from being caught by the bunching of the golf ball. In addition, since the ball has a higher elasticity, repulsive force, and frictional force than a golf ball, it is difficult to apply such a feeding device to a screen baseball.

As another example, Korean Registered Utility Model No. 20-0480032 discloses a golf ball automatic tee-up device including an engaging member for releasing a golf ball which is rotated in a reverse direction on one side of a ball feeder.

However, the automatic golf tee-up device of this type is only capable of releasing the golf ball rotating in the reverse direction, and has a limitation in that it can not prevent the golf ball from being caught by the bunch before being inserted into the ball insertion groove. Also, since the ball has a higher elasticity, repulsive force, and frictional force than a golf ball, it is difficult to apply such a tee-up device to a screen baseball.

In addition, although a number of techniques have been disclosed for preventing a golf ball from being caught in the process of accommodating and distributing a golf ball, it is common to distribute the golf ball at a low speed and a sequential order, In the case of a baseball ball, it is important to quickly distribute the ball at a high speed, so that it is common for the ball to rotate at a high speed. Therefore, there are limitations in applying techniques that can prevent the ball from being caught in order to prevent the ball from being caught.

The power section 400 includes a motor 410, a belt section 420, a rotating plate pulley 430, and a tension adjusting pulley 440.

The motor 410 provides power for rotating the rotating plate 200. The motor 410 can be supplied with electric power by a separate electric wire (not shown).

The rotational direction of the motor 410 can be changed. Therefore, the rotational direction of the rotary plate 200 can also be changed. However, as described above, it is preferable that the rotation direction of the motor 410 is determined according to the position of the pinch prevention member 160 for the soft motion.

Specifically, the balls are prevented from being directly brought into contact with the rotary plate 200 by the engagement preventing members 160 for the rotary type, so that the frictional force that may occur between the rotary plate 200 and the balls is reduced, 210).

At this time, the moving direction of the balls is affected by the rotating direction of the rotating plate 200. Therefore, when the rotation direction of the rotary plate 200 is changed, the direction of movement of the balls is changed, and accordingly, the position of the anti-jamming member 160 for the rotary shaft 200 is also changed.

In another embodiment, in consideration of the case where the rotating direction of the rotating plate 200 is changed, the left and right member connecting portions 122 may be provided with the anti-jamming preventing members 160 for the rotary shaft 200. In this case, The ball can be inserted into the ball insertion hole 210 only when the ball insertion hole 210 of the ball joint 210 is positioned at the end of the engagement member 160 for the soft ball.

Therefore, it is preferable that the pinch prevention member 160 for a soft feel is provided in one piece in order to smoothly insert the hole into the hole 210 for insertion.

The belt section 420 provides the power provided by the motor 410 to the spindle pulley 430, which will be described below. Alternatively, it may be provided with a chain or the like capable of transmitting rotational force.

The rotary plate pulley 430 is connected to a rotary shaft (not shown) of the rotary plate 200 and is connected to the belt unit 420. The rotary plate 200 can be rotated by the rotation of the rotary plate pulley 430.

The tension adjusting pulley 440 is coupled to the rear surface 130 of the ball collecting unit 100 so as to be slidable by a predetermined distance above the belt unit 420. The tension regulating pulley 440 may be located at any position where it can slide and be in contact with the belt portion 420, as will be described later.

A guide portion 442 for slidingly moving the tension adjusting pulley 440 in the vertical direction may be provided for sliding movement of the tension adjusting pulley 440.

The tension adjusting pulley 440 adjusts the tension of the belt portion 420 through contact with the belt portion 420. This process will be described later.

(5) Description of the control unit 500

The control unit 500 controls various matters related to the operation of the ball collecting device 36. For example, the control unit 500 may control the operation of the ball collecting device 36 by applying or cutting off power to the power unit 400. [

Referring to FIG. 14, the controller 500 includes a rotation determination module 510, a rotation number determination module 520, and a power control module 530.

The rotation determination module 510 determines whether the rotation plate 200 is rotating using the movement of the rotation plate 200 sensed by the rotation plate sensor 150 and whether a ball engagement phenomenon has occurred in the ball collecting device 36 .

The rotation number determination module 520 determines the number of rotations of the rotation plate 200 during a period of time sensed by the rotation plate sensor 150 by using the movement of the rotation plate 200 sensed by the rotation plate sensor 150, ) Is to be rotated in the reverse direction.

The power supply control module 530 controls the rotating plate 200 according to whether the spinning phenomenon determined by the spinning determination module 510 and the spinning number determination module 520 occurs and whether reverse rotation is required.

Specifically, when the rotation determination module 510 determines that a jamming phenomenon has occurred, the power source control module 530 shuts off the power supplied to the power unit 400 and stops the ball collecting device 36.

If the rotation number determination module 520 determines that reverse rotation is required, the power control module 530 controls the power unit 400 to rotate the rotation plate 200 in the reverse direction.

A process of controlling the ball collecting device 36 by the control unit 500 will be described later.

3. Description of the depth of the hole 210 of the turntable 200

4 and 5, the depth of the hole 210 is larger than the diameter of the hole. When the hole is inserted into the hole 210, the hole is not exposed on the entire surface of the rotary plate 200.

Referring to FIG. 5 (a), the rotating plate 200 rotates so that the ball insertion port 210a approaches the balls randomly scattered in the ball collecting space 110. When the turntable 200 continues to rotate, any one of the balls randomly scattered in the ball collecting space 110 is inserted into the ball insertion hole 210a.

The ball inserted into the ball insertion hole 210 is brought into contact with the rear surface 130 of the ball collecting unit 100 or the friction reducing member 224 by the depth of the ball insertion hole 210 and the inclination of the rotary plate 200 do.

Referring to FIG. 5 (b), the rotary plate 200 rotates to rotate the ball inserted into the hole 210a.

At this time, due to the depth of the ball insertion hole 210, the ball is completely received and is not exposed on the front surface of the turntable 200, so that it is rotated together with the turntable 200 without interference from other balls.

Therefore, even if the rotation plate 200 rotates after the ball is inserted into the ball insertion hole 210, the influence of other balls collected in the ball collection space 110 is minimized. Similarly, other balls collected in the ball collecting space 110 are also minimally affected by the balls inserted into the ball insertion hole 210.

Therefore, the ball inserted into the ball insertion hole 210 is not separated from the ball insertion hole 210 due to friction with other balls.

4. Description of the tension adjustment process of the belt portion 420 by the tension adjusting pulley 440

6 to 8, a tension adjusting pulley 440 is slidably coupled to the rear surface 130 of the ball collecting unit 100 on the upper side of the belt unit 420 as described above.

The distance between the belt portion 420 and the tension adjusting pulley 440 can be controlled by the operation of the guide portion 442. Specifically, the guide portion 442 can be positioned so that the tension adjusting pulley 440 is adjacent to but not in contact with the belt portion 420, and the tension adjusting pulley 440 can adjust the tension of the belt portion 420 The belt portion 420 may be positioned to be pressed.

To this end, a control unit (not shown) that can control the tension adjusting pulley 440 and the guide unit 442 may be further included.

Referring to FIG. 8A, the tension of the belt 420 is lowered and the belt 420 is lowered, and only a part of the power of the motor 410 is transmitted to the rotating plate pulley 430.

Referring to FIG. 8 (b), the tension adjusting pulley 440 is slid toward the belt portion 420 and presses the belt portion 420. As a result, the belt portion 420 is stretched and all the power of the motor 410 is transmitted to the rotary plate pulley 430.

At this time, it is preferable that the belt portion 420 is made of a material having elasticity so that the tension can be controlled by the tension adjusting pulley 440.

The distance by which the tension adjusting pulley 440 is moved and the degree to which the belt portion 420 is pressed can be adjusted based on the rotational speed of the rotating plate 200.

When the tension of the belt portion 420 is increased by the tension adjusting pulley 440 pressing the belt portion 420, the power of the motor 410 is transmitted to the rotating plate pulley 430 as it is.

Thus, the life of the belt portion 420 is improved, and the motor 410 (which may be caused by the rotation of the motor 410 at a higher speed due to the decrease in tension) can be used because the belt portion 420 can be used longer, Can be prevented from being overloaded.

5. Description of the process in which the ball is prevented from being caught by the engagement member 160

The balls collected in the ball collecting space 110 form a ball pile by their own weights and are held together. This is due to the characteristics of the baseball ball used in screen baseball.

Specifically, in the case of a baseball ball, unlike a golf ball, the ball has a high frictional force, which makes it difficult to disperse easily when the ball is united.

Particularly, in the case of a ball, which is a soft ball having outer and inner materials formed of rubber, the outer surface is formed of rubber, so that the friction force between the balls becomes higher, and the tendency of the ball to be more solidified can be strengthened.

Therefore, the ball collecting device 36 according to the embodiment of the present invention further includes the pinch prevention member 160 for preventing the balls collected in the ball collecting space 100 from being caught between the balls.

9 to 11, an anti-jamming preventing member 160 is formed to protrude from the member connecting portion 122 of the left side surface 120 of the ball collecting unit 100 to the inside of the rotating plate 200.

11 (a), the bottom portion 112 of the ball collecting space 110 is inclined toward the rotating plate 200, so that the balls collected in the ball collecting space 110 are directed toward the rotating plate 200 It becomes crowded. As described above, due to the nature of the ball, which is a soft ball, the balls become clumped.

At this time, as the rotating plate 200 rotates counterclockwise, the ball insertion hole 210b is moved to the lower side of the ball collecting space 110. At this time, the softened-piece preventing member 160 for the soft wire is inserted into the hole insertion hole 210b at the position where the hole is inserted, that is, the lowest position among the bottom portions 112 of the hole 110 (hereinafter, The ball is blocked from approaching the ball insertion hole 210b before the ball insertion hole 210b is rotated.

Therefore, the balls collected in the ball collecting space 110 are brought into contact with the pinch prevention member 160 for the soft segment, not the rotary block 200, while the ball insertion port 210b is rotated to the hole insertion position.

As described above, the softened-piece preventing member 160 for the soft feel is formed of a hard material having little frictional force, so that frictional force hardly occurs between the softened piece and the softened-piece preventing member 160.

In addition, since the play preventing member 160 for the soft wire prevents the ball from directly contacting with the rotating plate 200, the ball can be smoothly moved to the ball receiving opening 210 by preventing the ball from interfering with the rotating plate 200.

11 (b), the ball insertion hole 210b is rotationally moved to the ball insertion position. Then, the balls are gathered at the ball insertion position by the softened-piece preventing member 160 for a soft feel.

At this time, the balls gathered at the ball insertion position can be introduced into the ball insertion position in an orderly manner without being stuck together with the other balls by the engagement preventing member 160 for the soft segment. Therefore, it is possible to prevent the ball from being pinched with the ball or the rotary plate 200.

When the ball insertion hole 210b reaches the ball insertion position, one of the balls that have been flowed in order is inserted into the ball insertion hole 210b. In this case, since the balls are not bundled, there is a phenomenon in which balls are inserted between the ball before being inserted into the ball insertion port 210b and the bottom portion 112 of the turntable 200 and the ball collecting space 110, Can be prevented.

Further, since the hole is formed to be larger than the hole diameter, the hole can be completely accommodated, so that after the hole is received in the hole 210b, another hole is inserted or interference by another hole is not caused.

Therefore, before the ball is inserted into the ball insertion hole 210, the balls that have been gathered in the ball collection space 110 come into contact with the pinion prevention member 160 for the soft ball instead of the ball insertion hole 210, It is possible to prevent a phenomenon in which a ball is caught by the ball.

In addition, since the balls are smoothly moved by the pinch prevention member 160 when the balls move to the ball insertion position, the balls can be introduced into the ball insertion position one after another. Therefore, Can be prevented.

In addition, since the depth of the hole 210 of the rotary plate 200 is formed to be equal to or larger than the diameter of the hole, the hole is completely received, so that the hole inserted into the hole 210 may not be interfered with by other holes.

In addition, since the tension of the belt portion 420 of the power unit 400 can be adjusted by using the tension adjusting pulley 440, the life of the belt portion 420 can be prolonged while the rotational speed of the rotating plate 200 is kept constant. And the overload prevention effect of the motor 410 can be obtained.

6. Description of a method for controlling the ball collecting device 36 through the movement of the turntable 200 sensed by the turntable sensor 150

The control process of the ball collecting device 36 according to the embodiment of the present invention will be described in detail with reference to FIG. 14 and FIG.

In the following description, the term " reference time " means the maximum time during which the turntable 200 can be stopped under the condition that the ball collecting device 36 does not malfunction, Means the minimum number of rotations that must be reversed.

The reference time and the number of times of reference rotation may be variously determined according to the operating environment of the ball collecting device 36 and the like.

When the ball collecting device 36 starts operating, the rotating plate 200 starts to rotate, and the rotating plate sensor 150 senses the rotation of the rotating plate 200 (S110).

The rotation determination module 510 determines whether the rotation duration of the rotation plate 200 is equal to or longer than a reference time using the rotation of the rotation plate 200 sensed by the rotation plate sensor 150 at step S120. In the illustrated embodiment, the reference time may be 12 seconds.

The rotation determination module 510 determines that a jamming phenomenon has occurred in the rotary plate 200 in step S141 and the power control module 530 determines that the rotation of the power unit 400 And stops the ball collecting apparatus (S151).

When the stopping time of the rotating plate 200 is less than the reference time, the number of rotations of the rotating plate 200 is determined based on the number of rotations of the rotating plate 200 sensed by the rotating plate sensor 150, It is determined whether the number of revolutions is equal to or greater than the number of revolutions (S130). In the illustrated embodiment, the number of reference rotations may be ten.

When the rotation number of the rotation plate 200 is less than the reference rotation number, the rotation number determination module 520 determines that there is no problem in the ball collection device 36, The detection is repeated (S110).

The power control module 530 determines that the rotation of the power unit 400 is necessary when the number of revolutions of the revolving plate 200 is equal to or greater than the reference number of revolutions, So that the rotating plate 200 is rotated in reverse (S152).

Accordingly, it is determined in real time whether or not the ball collecting device 36 has been caught by the rotation of the turntable 200 sensed by the turntable sensor 150 and the number of revolutions, It can respond immediately.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the invention as defined in the appended claims. It can be understood that it is possible.
