- Recently, as interest in baseball has increased, the number of baseball practice fields where baseball can be practiced has increased.
- Such baseball practice fields are generally used in such a manner that when a pitching machine configured to pitch balls pitches a ball, a user standing in a batter's box hits the ball with a bat.
- In this case, a ball feeding device configured to continuously feed balls is commonly attached to the pitching machine, and the ball feeding device feeds balls from a ball accommodation part, in which balls have been collected, to the pitching machine by sequentially moving the balls.
- In this case, the ball accommodation part in which balls have been collected is generally formed in such a manner that the inner wall of the ball accommodation part is inclined to have a predetermined slope around a specific point so that balls can be moved along the inner wall of the ball accommodation part and placed on ball delivery arms by gravity.
- However, in the case where multiple balls are stacked on top of one another or balls are stuck on a boundary portion where the slope of the inner wall of the ball accommodation part changes, the balls cannot be moved along the inner wall of the ball accommodation part, and thus the balls cannot be placed on the ball delivery arms, with the result that a problem occurs in that balls cannot be fed to the pitching machine.
- Furthermore, even in the case where, since the speed at which a ball is fed is higher or lower than the speed at which the pitching machine pitches a ball, an appropriate number of balls cannot be fed to the pitching machine and thus the ball loading part is filled with balls, a problem occurs in that a ball is fed even in the case and thus a ball delivery device is damaged.
- In connection with this, the prior art document “Korean Patent Application Publication No. 10-1991-0009302” relates to an automatic golf ball feeding apparatus. The patent publication discloses only an apparatus configured to arrange balls, fed from a stoker configured to accommodate a plurality of golf balls, along a path in a line so that the balls can be freely shaken and to enable golf balls to be discharged via an exit one by one, thereby delivering the balls. The patent publication does not propose an apparatus capable of arranging balls in a ball accommodation part by means of a mixing arm and capable of detecting the number of balls waiting for pitching in a pitching machine and controlling the operation of a ball delivery device (or ball feeding device).
- Accordingly, there is a need for technology capable of overcoming the above-described problems.
- Meanwhile, the above-described background technology corresponds to technical information which has been possessed by the present inventor in order to contrive the present invention or which has been acquired in the process of contriving the present invention, and can not necessarily be regarded as a well-known technology which had been known to the public prior to the filing of the present invention.

FIG. 1 is a view showing an example in which a ball feeding system including a ball delivery device and a ball feeding device according to an embodiment of the present invention is installed. - A
ball feeding apparatus 100 shown inFIG. 1 may be configured such that balls are sequentially delivered by aball delivery device 10, the balls are be introduced into aball feeding device 20 configured to feed balls to a pitching machine, and the operation of theball delivery device 10 is controlled based on the number of balls introduced into theball feeding device 20 and loaded in a line. - As shown in
FIG. 1 , theball delivery device 10 may include aball accommodation part 11 configured to accommodate one or more balls. - The
ball accommodation part 11 may be formed in an empty pyramid shape having a closed curve-shaped circumference in order to accommodate balls, i.e., a shape the length of the circumference of which becomes narrow in a direction from the upper end thereof to the lower end thereof, preferably a quadrangular pyramid shape. - Furthermore, the
ball delivery device 10 may include aball delivery post 12, i.e., a delivery post formed vertically from a support surface to deliver balls vertically from theball accommodation part 11. - In this case, fixed pulleys may be provided at the upper and lower ends of the
ball delivery post 12, achain 14 may be closely engaged with the fixed pulleys, and a drive motor (not shown) may be provided on theball delivery post 12 in order to move thechain 14. Preferably, the drive motor may be provided at the lower end of theball delivery post 12. - Furthermore, the
ball delivery device 10 may includeball delivery arms 13 each formed in a shape capable of fastening a ball in order to hold and deliver a ball in theball accommodation part 11 and each configured to deliver a ball along theball delivery post 12. - The
ball delivery arms 13 may be coupled with thechain 14, and may be moved upward and downward along theball delivery post 12 by thechain 14 which is moved by the drive motor (not shown) of theball delivery post 12. - Furthermore, the
ball delivery device 10 may include mixingarms 15 configured to be coupled with thechain 14 at predetermined intervals with theball delivery arms 13, to be moved upward and downward along theball delivery post 12, and to mix balls accommodated in theball accommodation part 11. - Furthermore, the
ball feeding device 20 configured to receive balls delivered by theball delivery device 10 may include aball introduction part 21 configured such that balls delivered by theball delivery device 10 are introduced thereinto, and may further include aball loading part 22 connected to theball introduction part 21 and configured to load balls so that the balls can be sequentially delivered to the pitching machine. - Furthermore, the
ball loading part 22 may be formed to have an inner diameter similar to that of balls so that introduced balls can be sequentially loaded in a line, and may be preferably formed in a column shape. However, theball loading part 22 is not necessarily limited to the column shape, but may be formed in a polygonal prism shape the length of the diagonal line of which is similar to the diameter of balls so that introduced balls can be sequentially loaded in a line. - In this case, the
ball loading part 22 may be made of a freely deformable material, preferably a plastic material. - Furthermore, the
ball feeding device 20 may include aball sensor part 23 configured to detect the number of balls loaded in theball loading part 22. Theball sensor part 23 may include one or more sensors. The sensors may be located at the lower end portion of theball loading part 22, and may detect loaded balls. - Meanwhile,
FIG. 2 shows the appearance of the side of theball delivery device 10, more specifically theball delivery arms 13 and the mixingarms 15 sequentially arranged along theball delivery post 12. - As shown in
FIG. 2 , in theball delivery device 10, theball delivery arms 13, and the mixingarms 15 may be disposed along aball delivery post 12, formed vertically from the support surface, at predetermined intervals. - In this case, according to an embodiment, the
ball delivery arms 13 and the mixingarms 15 may be alternately disposed, or each mixingarm 15 may be disposed after a predetermined number ofball delivery arms 13 have been successively disposed. - Furthermore, the
ball delivery arms 13 and the mixingarms 15 may be lifted vertically from the support surface on one side surface of theball delivery post 12, may reach the upper end of theball delivery post 12, may be moved to the other side surface of theball delivery post 12, and may be then lowered to the support surface. - The
ball delivery post 12 along which theball delivery arms 13 and the mixingarms 15 are lifted through movement may be located on one side of theball accommodation part 11. The liftedball delivery arms 13 may hold and deliver balls accommodated in theball accommodation part 11 while passing through a ball delivery point, i.e., a point at which the liftedball delivery arms 13 pass through theball accommodation part 11. - Furthermore, the mixing
arms 15 may pass through theball accommodation part 11 while being lifted along with the movement of theball delivery arms 13. The mixingarms 15 may apply physical force to balls accommodated in theball accommodation part 11 while passing through theball accommodation part 11, thereby moving the locations of the balls and thus mixing the balls. - Meanwhile,
FIGS. 3 to 5 show, in detail, the mixingarm 15 provided on theball delivery device 10 and configured to mix balls accommodated in theball accommodation part 11. The mixingarm 15 will be described in detail with reference to the drawings. - As shown in
FIG. 3 , the mixingarm 15 is formed in a “T” shape. The mixingarm 15 includes: a mixingplate 151, i.e., a flat member formed to be parallel to the support surface and to be disposed perpendicular to acoupling plate 152 so that it is perpendicular to the extension direction of theball delivery post 12; and acoupling plate 152, i.e., a flat member configured to be coupled to thechain 14 and to be disposed parallel to the extension direction of theball delivery post 12. - Furthermore, the mixing
arm 15 may include asupport plate 153, i.e., a flat member disposed to be perpendicular to one surface of the mixingplate 151 and to be perpendicular to the plane of thecoupling plate 152 in the direction of an internal angle formed between the mixingplate 151 and thecoupling plate 152. - The
support plate 153 may distribute force applied to themixing plate 151 to thecoupling plate 152 or support the mixingplate 151 between the mixingplate 151 and thecoupling plate 152, thereby preventing the mixingplate 151 from being bent. - Referring to
FIG. 4 , the mixingplate 151 may be formed in a “T” shape. Thecoupling portion 400 of the mixingplate 151 which is coupled to thecoupling plate 152 may be formed to have a length equal to the width of theball delivery post 12. The mixingportion 401 of the mixingplate 151 extending from theball delivery post 12 in a direction perpendicular to the extension direction of theball delivery post 12 may be formed to have a width which becomes narrower as it becomes away from thecoupling portion 400 in a perpendicular direction. - Although the shape of the mixing
portion 401 is preferably a triangular shape, it is not necessarily limited to the triangular shape. - Furthermore, since the mixing
arm 15 has the above-described shape, contact areas which come into contact with balls are reduced, so that a large amount of force is not required when the mixingarm 15 passes between balls accommodated in theball accommodation part 11, and so that the abrasion of balls attributable to friction with the mixingplate 151 can be minimized. - Furthermore, the mixing
plate 151 may be formed to be longer than theball delivery arm 13, and thus a range which can be reached by the mixingplate 151 may become wider within theball accommodation part 11. This enables theball delivery arm 13 to apply physical force even to a ball located outside the ball delivery point, at which a ball is held in order to deliver the ball, in theball accommodation part 11, thereby effectively overcoming a ball catch or jam phenomenon in theball accommodation part 11. - Referring to
FIG. 5 , thesupport plate 153 may be located on a side on which an internal angle is formed by the mixingplate 151 and thecoupling plate 152 so that a bent formed between the mixingplate 151 and thecoupling plate 152 can be maintained and the mixingplate 151 can be supported. - Since the mixing
arm 15 passes between balls accommodated in theball accommodation part 11 via thesupport plate 153, force applied to themixing plate 151 can be distributed to thecoupling plate 152, and the mixingplate 151 can be prevented from being bent. - The
ball delivery device 10 can overcome a ball catch or jam phenomenon in theball accommodation part 11 by using the mixingarm 15 having the above-described shape. This will be described with reference toFIG. 6 . -
FIG. 6 is a view showing an example of a situation in which balls are delivered by means of the ball delivery arm by moving the locations of balls stuck in theball accommodation part 11 via the mixingarm 15 according to an embodiment of the present invention. - A
first situation view 601 shows a situation in which theball delivery arm 131 cannot deliver aball 600 becauseballs 600 accommodated in theball accommodation part 11 are located outside the ball delivery point of theball accommodation part 11. - In other words, in the case where the
balls 600 are not moved to the ball delivery point located at the lowest point of theball accommodation part 11 along the inclined inner wall of theball accommodation part 11 and thus theballs 600 are located outside the ball delivery point of theball delivery arm 131 because theballs 600 are stopped outside the ball delivery point of theball accommodation part 11 due to the surface bents of the balls 60, theballs 600 are stuck on the bent of a boundary portion where the slope of the inner wall of theball accommodation part 11 changes, or the like, theballs 600 cannot be placed on theball delivery arm 131. - Thereafter, in a
second situation view 602, the mixingplate 151 of the mixingarm 15 can apply physical force to theballs 600 while the mixingarm 15 located next to theball delivery arm 131 of thefirst situation view 601 is passing through the ball delivery point of theball accommodation part 11, and thus theball 600 to which physical force has been applied is moved to the ball delivery point ball of theaccommodation part 11. - In this case, preferably, the length of the mixing
plate 151 of the mixingarm 15 is formed to extend longer than that of theball delivery arms ball accommodation part 11 through which the mixingarm 15 passes becomes larger than that through which theball delivery arms - Thereafter, the
ball 600 located at the ball delivery point of theball accommodation part 11 can be delivered by theball delivery arm 132 located next to the mixingarm 15. - The locations of the balls accommodated in the
ball accommodation part 11 are changed by applying physical force to the balls via the mixingarm 15, and thus balls are moved along the inner wall of theball accommodation part 11, thereby enabling the ball to be located at the ball delivery point of theball accommodation part 11. - This enables the
ball delivery device 10 to successively place balls on theball delivery arms 13. - Meanwhile,
FIG. 7 is a view showing, in detail, theball loading part 22 configured such that balls delivered by theball delivery device 10 are introduced and then loaded into theball feeding device 20 and theball sensor part 23 configured to detect the number of loaded balls. - Referring to this drawing, balls introduced into the
ball introduction part 21 of theball feeding device 20 may be sequentially loaded along theball loading part 22, and theball sensor part 23 may detect the number of balls loaded into theball loading part 22. -
FIGS. 8 to 9 are views showing, in detail, the inside of theball sensor part 23 with an outer casing removed therefrom. Theball sensor part 23 will be described in detail with reference to this drawing. - The
ball sensor part 23 may include one ormore sensors 231 configured to detect balls loaded onto the side surfaces of thereof, preferably threesensors 231. Thesensors 231 may be attached onto the side surface of theball loading part 22. - In this case, the
sensors 231 can detect balls which are sequentially loaded along theball loading part 22. - Each of the
sensors 231 includes a sensor body and a button configured to be retracted into the sensor body. Thesensor 231 may be a button-type sensor in which, as pressure is applied to the button by a ball loaded into theball loading part 22, the button is retracted into the sensor body and thus the ball is detected. - However, the
sensors 231 are not necessarily limited to the above-described button-type sensors, but may be sensors using an infrared ray, a laser beam, or the like adapted to detect an object, pressure sensors, or the like. - Furthermore, the
ball sensor part 23 may include an opening and closingmember 232 configured to control the opening and closing of a path for balls so that balls loaded into theball loading part 22 can be sequentially provided to the pitching machine. - The opening and closing
member 232 may include a blocking rod member configured to block the path for balls and an opening and closing member coupled to the blocking rod member and configured to operate the blocking rod member. - Furthermore, the
ball sensor part 23 may include a control unit (not shown) configured to control the operation of theball delivery device 10 based on the number of loaded balls detected via thesensors 231. The control unit (not shown) may control the operation of the drive motor (not shown) configured to provide power to thechain 14 of theball delivery device 10. - Meanwhile,
FIG. 9 is a view showing an example of a situation in which a ball is loaded into theball loading part 22 and detected by the sensor. - Referring to this drawing, a
ball 900 introduced into theball introduction part 21 may be moved along theball loading part 22 and stopped and loaded by the opening and closingmember 232, and the loadedball 900 may press thesensor 231 of theball sensor part 23. - Accordingly, the control unit (not shown) of the
ball sensor part 23 may detect theball 900 being loaded into theball loading part 22, and may control the opening and closingmember 232 such that theball 900 is provided to the pitching machine. - In this case, when a predetermined number of
balls 900 are loaded into theball loading part 22 and all thesensors ball sensor part 23 detect balls, the control unit (not shown) of theball sensor part 23 may stop the operation of theball delivery device 10. - Preferably, when three
balls 900 are loaded into theball loading part 22 and the buttons of the first tothird sensors 231 a to 231 c are pressed, the operation of theball delivery device 10 may be stopped. - Meanwhile, the location of the control unit (not shown) of the
ball sensor part 23 is not necessarily limited to theball sensor part 23, but may be located in theball delivery device 10. In this case, theball delivery device 10 may detect the number of balls in theball loading part 22, and may then control the delivery of balls. - In other words, unlike a method in which the
ball delivery device 10 operates whenever a ball is pitched by the pitching machine, the present invention is configured such that balls are loaded into theball loading part 22 and the operation of theball delivery device 10 is controlled based on the number of balls. Accordingly, the time it takes for a ball to be delivered and reach the pitching machine is not required, and thus an effect is achieved in that delay time does not occur when a ball is pitched. - Meanwhile,
FIG. 10 is a flowchart showing the control operation of theball feeding system 100 according to an embodiment of the present invention. A method by which theball feeding system 100 controls the feeding of a ball will be described with reference to the drawing. - First, the
ball feeding system 100 may deliver balls, accommodated in theball accommodation part 11, via theball delivery arms 13 by operating theball delivery device 10 at step S1001. - Furthermore, the
ball feeding system 100 may sequentially load balls into theball loading part 22 by introducing the balls, delivered by theball delivery arms 13, into theball introduction part 21 of theball feeding device 20 at step S1002. - Thereafter, the
ball feeding system 100 may determine whether a number of balls equal to or larger than a predetermined number have been loaded into theball loading part 22 at step S1003. - For example, the
ball feeding system 100 may determine whether three or more balls have been loaded into theball loading part 22. - Furthermore, when it is determined at step S1003 that a number of balls equal to or larger than a predetermined number have been loaded, the
ball feeding system 100 may stop the operation of theball delivery device 10 at step S1004. - Furthermore, the
ball feeding system 100 may determine whether the operation of the pitching machine has been stopped at step S1005, and may repeat step S1003 until the operation of the pitching machine is stopped. - The ball delivery control method according to the embodiment, which is shown in
FIG. 10 , includes steps which are processed by theball feeding system 100 shown inFIGS. 1 to 9 in a time series manner. Accordingly, an item which is omitted in the following description but has been described in conjunction with theball feeding system 100 shown inFIGS. 1 to 9 may be also applied to the ball delivery control method according to the embodiment shown inFIG. 10 . - The ball delivery control method according to the embodiment described via
FIG. 10 may be implemented in the form of a storage medium including computer-executable instructions, such as a computer-executable program module. The computer-readable medium may be any computer-accessible available medium, and includes all volatile and nonvolatile media and separable and non-separable media.

The computer program includes programmable machine instructions that are processed by a processor, and may be implemented as high-level programming language, object-oriented programming language, assembly language, machine language or the like. Furthermore, the computer program may be stored in a tangible computer-readable storage medium (for example, memory, a hard disk, a magnetic medium, an optical medium, a Solid-State Drive (SSD), or the like).
- Accordingly, the ball delivery control method according to the embodiment of the present invention may be implemented in such a manner that the above-described computer program is executed by a computing device. The computing device may include at least a part of a high-speed interface coupled to a processor, memory, a storage device, and memory and a high-speed extension port, and a low-speed interface coupled to a low-speed bus and a storage device. These components are coupled to each other using various buses, and may be mounted on a common mother board or may be mounted using another appropriate method.
- In this case, the processor may process instructions within a computing device. These instructions are, for example, instructions that are stored in memory or a storage device in order to display graphic information adapted to provide a Graphic User Interface (GUI) onto an external input or output device, such as a display coupled to a high-speed interface. As another embodiment, a plurality of processors and/or a plurality of buses may be used along with a plurality of pieces of memory and a plurality of memory forms. Furthermore, the processor may be implemented as a chipset composed of chips including a plurality of independent analog and/or digital processors.
