Pitching machine

Abstract

The present invention relates to a pitching machine. According to the present invention, an upper wheel ( 13 ) and a lower wheel ( 14 ) are disposed such that motors ( 11 ) and ( 12 ) are each disposed on a central shaft on one surface and a ball is pitched using the rotation driven by the motor. A ball supply container ( 15 ) and a ball supply device ( 16 ) are disposed on one side of the upper wheel ( 13 ) and lower wheel ( 14 ) so as to supply the ball to the upper and lower wheels. A stepper motor ( 18 ) is connected to the central shaft of the upper wheel ( 13 ) and lower wheel ( 14 ) so as to adjust the directional angle of the upper and lower wheels according to the angular direction of the ball. A body rod ( 20 ) supporting one side of the upper and lower wheels, the stepper motor ( 18 ), and the ball supply container ( 15 ) are connected to a triangular supporting leg ( 21 ) at the lower portion so as to support the body rod ( 20 ). According to the pitching machine, a hitter can practice hitting alone by selecting various angle, direction and speed patterns.

1 . A pitching machine configured to have a batter to practice batting, comprising:
 an input unit configured to select a pitching type, direction, and speed of a ball when a batter practices batting;   a CPU and a memory unit configured to store input signals of the pitching type, direction, and speed of the ball selected by the input unit and to instruct an operation signal stored by calculating a pitching type, direction, and speed of the ball;   a control unit configured to selectively send a command to motors of upper and lower wheels, a pitching type motor, and a ball supply motor in response to a command signal received from the CPU; and   a control box configured to comprise a driving unit for pitching balls by driving sensors and drives in response to a command from the control unit.   
     
     
         2 . The method of  claim 1 , wherein the input unit receives commands of the pitching type, direction, and speed of a ball using any one of manipulation methods using a remote controller (IR), a manual manipulation (Key), and a PC. 
     
     
         3 . The method of  claim 1 , wherein the driving unit comprises upper and lower wheel drives connected to an RPM sensor, a pitching type drive connected to an encoder sensor, and a supply drive supplied to a proximity sensor. 
     
     
         4 . A pitching machine configured to have a batter to practice batting, comprising:
 an upper wheel  13  and a lower wheel  14  configured to have respective motors  11  and  12  installed in a central shaft of the upper and lower wheels on one side thereof and installed so that balls are able to be pitched while being rotated by the driving of the motors;   a ball supply container  15  and a ball supply device  16  installed on one side of the upper and lower wheels  13  and  14  and configured to supply balls to the upper and lower wheels;   a stepping motor  18  connected to the central shaft of the upper and lower wheels  13  and  14  and configured to control direction angles of the upper and lower wheels in response to a pitching type direction of a ball;   a body rod  20  configured to support one sides of the upper and lower wheels, the stepping motor  18 , and the ball supply container  15 ; and   triangular support legs  21  connected to a bottom of the body rod  20  so that the triangular support legs  21  support the body rod  20 .   
     
     
         5 . The method of  claim 4 , wherein the ball supply device  16  has a proximity sensor  46  installed at each of corners of ball supply wings  17 . 
     
     
         6 . The method of  claim 4 , further comprising a plurality of wheels  47  installed on one side of the pitching machine so that the pitching machine is able to be separated from the triangular support legs and is rolled and moved.
