Benefits of technology
The sphere-launching apparatus includes a launching tube, push unit, and pneumatic unit. The push unit is mounted to the first axial end and includes a push rod and a first driving device. The pneumatic unit includes a valve mechanism, pneumatic cylinder, and air container. The valve mechanism controls the push rod to push the sphere to move axially along the launching passage. The pneumatic cylinder drives the valve mechanism to block or open the air-emitting end. The air container stores the compressed air. When the valve mechanism opens the air-emitting end, the compressed air stored in the air container would be released into the launching passage so as to eject the sphere out of the launching tube via the second axial end. The technical effects of the sphere-launching apparatus include accurate sphere launching, synchronized push rod action, and efficient pneumatic operation.
Problems solved by technology
However, due to some unexpected structural factors, angles, directions and distances of the ejected spheres can't be kept the same, or even within acceptable ranges.

Embodiment Construction
[0019]The invention disclosed herein is directed to a sphere-launching apparatus. In the following description, numerous details are set forth in order to provide a thorough understanding of the present invention. It will be appreciated by one skilled in the art that variations of these specific details are possible while still achieving the results of the present invention. In other instance, well-known components are not described in detail in order not to unnecessarily obscure the present invention.
[0020]Referring now to FIG. 1, the sphere-launching apparatus 100 mainly includes a launching tube 10, a push unit 20 and a pneumatic unit 30.
[0021]As shown in FIG. 1, the launching tube 10 has a first axial end 11 and a second axial end 12 located oppositely to the first axial end 11. Inside the launching tube 10, a launching passage 13 is defined to communicate spatially the first axial end 11 and the second axial end 12. An axial (i.e., longitudinal) direction of the launching tube ...

A sphere-launching apparatus includes a launching tube defining a launching passage, a push unit having a push rod and a first driving device, and a pneumatic unit having a valve mechanism, a pneumatic cylinder and an air container. The push rod, to protrude axially into the launching passage, has a third axial end and an opposing fourth axial end for contacting a sphere in the launching tube. The first driving device, connected with the third axial end, controls the push rod to move the sphere along the launching passage to a predetermined position. The valve mechanism has an air-emitting end connected spatially with the launching passage. The pneumatic cylinder drives the valve mechanism to block or open the air-emitting end. When the valve mechanism opens the air-emitting end, a compressed air in the air container is discharged into the launching passage to eject the sphere out of the launching tube.
Description
BACKGROUND OF THE INVENTION(1) Field of the Invention[0001]The invention relates to a sphere-launching apparatus, and more particularly to the sphere-launching apparatus that can have all spheres or spheroids it carries to be launched at the same initial position and by the same speed.(2) Description of the Prior Art[0002]Currently, various ball-launching machines have been already seen in the marketplace to launch spheres or spheroids, such as tennis balls, baseballs, gulf balls and pingpong balls, and helpfully to facilitate ball games and / or training.[0003]A typical conventional ball-launching machine mainly includes a launching tube. One lateral side of the launching tube is usually connected spatially with a ball-supplying duct for providing spheres to enter the launching tube. An axial end of the launching tube is generally furnished with a compressed-air launching device that is further connected with an air container. While a compressed air inside the air container is quickl...
