PROCESS AND APPARATUS FOR BUFFING GOLF BALLS
A method and apparatus for automatically removing flash along the parting line of a golf ball, especially when the parting line is wavy or corrugated. The apparatus is also effective for removing flash from golf balls that are not completely spherical, or golf balls that are void of tabs or annular ring which are commonly used for alignment. The method removes flash from a golf ball by using a mapping device comprising either a vision orientation system or a laser means incorporating comprises high resolution CCD displacement sensors on a servo controlled vertical axis to properly place the ball in position wherein a cutter and buffer are maneuvered along a mapped contour of the flash that is captured by the coordinated motion logic of a computer.
1 . A method for automatically buffing flash off a golf ball comprising the steps of:
providing the golf ball from a supply hopper to an orientation device;
orienting the ball to a specific plane position;
identifying a location, a length and a thickness of the flash in relation to the profile of the ball by using a mapping device;
picking the golf ball and placing the ball into a rotating spindle cup without any change in the orientation;
providing a computer system having coordinated motion logic to capture the information from the mapping device and produce a mapped contour of the flash in relationship to a profile of the ball;
removing the flash by an adjustable cutter that responds to commands from the computer's coordinated motion logic and removes only flash along the ball profile;
buffing the golf ball with a flexible profiled sanding belt whose motion is controlled by the coordinated motion logic of the computer; and
removing the buffed ball from the spindle cup and forwarding it for further processing.
2 . The method of claim 1 , wherein the adjustable cutter comprises an angled and contoured cutting edge that compliments the profile of the ball.
3 . The method of claim 1 , wherein the mapping device comprises a vision orientation system.
4 . The method of claim 3 , wherein the vision orientation system positions a golf ball without alignment tabs.
5 . The method of claim 3 , wherein the vision orientation system positions a golf ball that is without an annular ring for alignment.
6 . The method of claim 1 , wherein the mapping device comprises high resolution CCD displacement sensors on a servo controlled vertical axis.
7 . The method of claim 1 , wherein the flash is located along a wavy parting line.
8 . The method of claim 1 , wherein the golf ball may be ±0.008 inch out of round.
