<p>The occurrence of vibrations in the vertical direction caused by vibrations in the horizontal rotation direction is inhibited in a complex-vibration-type bowl feeder. In a vibrating bowl feeder, a cross-shaped moveable frame (4) in which four radially extending arms (4b) are formed at equidistant intervals in the peripheral direction is provided between an upper vibrating body (2) and lower vibrating body (3) to which a bowl (1) is attached, the upper vibrating body (2) and the moveable frame (4) are coupled together by a spring (5) for rotational vibration, and a the moveable frame (4) and the lower vibrating body (3) are coupled together by a rectangular frame-shaped spring (6) for vertical vibration. The spring (5) for rotational vibration extends horizontally outward is the radial direction of the moveable frame (4), with one end part secured to an arm (4b) of the moveable frame (4) and the other end part secured to a leg (2a) of the upper vibrating body (2).</p> |
