ABSTRACT:
A long-travel annular vibratory barrel finishing apparatus for line-processing having an annular vibratory barrel constituted by at least one barrel line having opposing end barrel segments having a semicircular shape in plan and two straight barrel sections connected between opposing end barrel segments, such that the longer diameter (length) of said annular barrel is much greater than the shorter diameter (breadth) of the same. The annular vibratory barrel as a whole is mounted on a base through a plurality of springs for free vibration which is caused by a vibrator disposed at the center of the longitudinal axis of the annular vibratory barrel. As the vibrator is started, the annular vibratory barrel is vibrated to cause a spiral flow of mass therein. A workpiece transfer device is installed in association with the annular vibratory barrel or, alternatively, workpiece charging device and a workpiece separating device are provided on the annular vibratory barrel, so that successive workpieces are line-processed automatically and continuously. The workpiece transfer device is arranged above the annular vibratory barrel in parallel with the latter, and are adapted to drive spindles carrying workpieces along the barrel while rotating the spindle.
