摘要： A shuttlecock-throwing machine is provided to permit delivery of successive shuttlecocks at different frequencies, trajectories and speeds. The machine includes a shuttlecock dispenser, a feeding mechanism and an ejecting unit. The ejecting unit consists of two motors-driven recoiling counter rotating wheels being fed successively by the feeding mechanism therein gripping the shuttlecock's cap or nose and propelled the shuttlecock in the path of wheels plane. The shuttlecock dispenser comprising a pair of parallel or spiral bar, spaced apart and set at an incline to queue shuttlecocks with the noses side down over the feeding mechanism. The feeding mechanism consists of a motor-driven four-spoke rotor which draw the shuttlecocks from its dispenser and deliver one by one into the ejecting device.

摘要： A ball launching apparatus configured to launch balls to a user. The ball launching apparatus is configured such that a user may change an angle of trajectory T of launched balls by simply resting the ball launching apparatus on one of two different base portions. The ball launching apparatus is configured to receive, feed, and launch balls having different shapes, such as baseballs and footballs. A ball feed mechanism of the ball launching apparatus is driven by ball propulsion mechanism of the ball launching apparatus.

摘要： A pitching system is provided for throwing baseballs, softballs and the like, which machine is synchronized to work in conjunction with a video display means to permit a batter to visually view a pitcher prior to and during delivery of the pitch. The machine includes a power head having at least two and preferably three coacting wheels for propelling a ball toward a batter to simulate a pitch. Three AC motors and companion motor drives are provided for causing the wheels to rotate at predetermined speeds. The motor drives include dynamic braking circuits to permit rapid deceleration of the wheels. A pair of linear actuators is provided to permit the power head to be moved to predetermined horizontal and vertical positions. A programmable controller is included for individually controlling the rotational speed of each individual wheel, the horizontal position of the power head and the vertical position of the power head. A smart card reader may be employed for programming of the controller and the machine is adapted to be used in conjunction with a video display to simulate the actual pitching of a baseball by a pitcher. The machine is able to interchangeably deliver pitches of different types to different locations at different speeds with less than ten-second intervals between pitches. A video display device is included for displaying a moving video image upon a screen situated adjacent to the pitching system. Said screen has an aperture therein for allowing unobstructed passage of the ball therethrough. The propelling of the ball and the moving image of the pitcher are synchronized by means of a programmable control unit, which chooses the video image appropriate for a particular pitch and instructs the wheels to rotate at the appropriate speeds for said pitch, as well as instructing the machine to assume a horizontal and vertical angular position appropriate for such pitch. When the programmable control detects that the wheels have assumed the appropriate speeds and the machine has assumed the appropriate horizontal and vertical angular position, the control unit initiates the playback of the video image and, after a predetermined interval of time, signals a solenoid to impel the ball into pitching machine so that the ball appears to be thrown by the image of the pitcher.

摘要： An improved ball pitching apparatus for a ball pitching machine of the type having an upper and lower wheel, said wheels rotating on substantially parallel shafts and having generally aligned and spaced rims carrying peripheral ball gripping bands; independent speed controlled drive motors; a ball feeder for feeding the ball between the spaced rims so that the ball will be gripped and accelerated in a trajectory tangential to the rims; a head frame carrying the wheels, drive motors, and ball feeder; and, a stand carrying the head frame. The improvements comprise: 1) a singular gripping band on one wheel and two spaced gripping bands on the other wheel so that the ball contacts and is gripped by three discrete points on its peripheral surface; 2) one of the wheels rotating on a shaft biased towards the other wheel so that the ball to be pitched will be gripped with a similar force regardless of diameter variations; and, 3) wheel drive DC motors internally positioned within the wheel so that the shafts and bearings in the motors are directly and radially loaded when the ball is gripped and accelerated. Internally driven wheels facilitate microprocessor and programmed memory control of a servo motors to control rotation of the head frame on the stand. This arrangement enables quick and precise adjustment to different pitching positions.

The ball-positioning mechanism further comprises an elevation control motor and a sway control motor, while the ball-projecting mechanism comprises a ball-conveying device and a ball-projecting device. A ball-collecting tray is arranged to collect plural balls, which will be delivered via a conveyer from the service machine body to the ball-projecting device sequentially through the ball-positioning mechanism and a spin. control motor for projection. The micro-controller can be set by a user or provided with a preset program to enable the service machine to shoot spun balls one after another at various angles or directions in continuous or intermittent mode automatically or manually.
