A first gate opens obliquely downward, and maintains the posture, rendering the slope angle of the bottom surface thereof steeper than that of the bottom surface of the second gate. Thus, the bottom surface of the second gate forms a gentle slope sliding surface, and the bottom surface of the first gate forms a steep slope sliding surface. Then articles drop following the shape of a parabola toward the bottom surface of the first gate on the steep slope side, with momentum gained from sliding down the bottom surface of the second gate on the gentle slope side, and then change the sliding trajectory inward upon bumping into the bottom surface of the first gate. The articles then drop following the shape of a parabola toward the center area of a dispersal table, with momentum gained from sliding down the bottom surface of the first gate.

Weighing device having gates for casting article onto center area of dispersal table, and method of driving gates of weighing device

A weighing apparatus of the type which weighs articles through use of a load cell having strain gauges attached thereto, the apparatus including a sealed vessel filled with a liquid of a specific gravity greater than unity for housing the load cell which is immersed in the liquid, a diaphragm provided on the sealed vessel so as to close an opening formed in a portion of the vessel, a supporting member for supporting a container carrying the articles to be weighed, and a connecting member for mechanically connecting the supporting member with a load-receiving portion of the load cell through the intermediary of the diaphragm.
