<p>PROBLEM TO BE SOLVED: To provide a vibration-type part conveyance apparatus for conveying parts linearly which is suppressed in yawing and pitching movements of part conveyance members.SOLUTION: Reaction forces of vibrations of an upper vibration system and a counter vibration system are caused to occur on the same XZ plane P by arranging symmetrically the center J1 of gravity of the upper vibration system, including a trough 20 for alignment and supply and an electromagnet 9, which vibrates integrally with an upper vibrator 1 and the center J2 of the gravity of the counter vibration system, including a movable iron core 8, which vibrates integrally with a counter vibrator 4, and the reaction force in the X direction becomes symmetric to the plane P, directed reversely with the same magnitude, and cancelled, suppressing occurrence of a moment around the Z axis passing the center of gravity of a base 2 and a moment around the Y axis passing the center of gravity of the base 2, so as to suppress yawing and pitching movements of the trough 20 for alignment and supply.</p> |
