SMALL BALL DISCHARGING DEVICE AND SMALL BALL DISCHARGING METHOD

摘要

PROBLEM TO BE SOLVED: To discharge a small ball in the stable state using parts which can be easily machined in a small ball discharging device constituted by a rail, a roller and a body of rotation provided with a lever supporting the roller by supporting the small ball with the roller at two points in capable of guiding. ;SOLUTION: A lever 2 extending from a driving source and rotatable around a center O supports a roller 3 with a shaft 4 in capable of rotation, and the roller 3 is brought into contact with a small ball 1. The small ball 1 is in touch with an inner circumferential face 5' of a rail 5, is rolled from the A position to B, C and D and is discharged from a discharge port, 6 of the rail 5 following the trajectory of E and F by the lever 2 rotating around the center O. And with the inner circumferential face 5' of the rail 5 as a cylindrical face with continuing planes, while the small ball 1 is brought into contact with a slope of the roller 3, brought into contact with the rail inner circumferential face 5' and rotated, the small ball 1 is in point contact with the slope 3' of the roller 3 and rolled. Here, the slope of the roller 3 is formed in the V-groove or U-groove state, and the small ball 1 is supported with the roller 3 at two points in capable of guiding.;COPYRIGHT: (C)1999,JPO
