You require a rotating chamber with 6 radial slots in a circle to fit balls. Three openings let one set of 3 balls into opening and 3 balls discharge from adjoining alternating openings when rotated 60 degrees. The horizontal plane above and below the ball containers is alternately allowing entry or discharge but not both. In this way, balls can enter the rotating chamber, but are blocked from leaving until a 60 degree rotation places the balls over the exit holes. If you require 2 instead of 3 then each 90 degree rotation accomplishes the same.

Hope this is clear enough to be of help.
