Abstract:
1. A workpiece feeder for separating, adjusting, and feeding workpieces, comprising: an adjustment-and-separation unit that separates the workpieces from one another and adjusts the workpieces into correct top-bottom orientation by reversing incorrectly oriented ones oaf the workpieces; and an alignment-and-feed unit that individually holds the separated and adjusted workpieces and horizontally aligns the held workpiece into correct planar posture by turning the held workpiece while feeding the held workpiece to a destination, the adjustment-and-separation unit including a base, a movable part having a stage surface on which the workpieces are placed and being movably supported with the base so as to shift the stage surface, and a drive part that applies separate impacts to the movable part so that the movable part moves to apply a bouncing force and a shifting force orthogonal to the bouncing force due to the separate impacts to the workpieces and thereby carry out the separation and adjustment of the workpieces, wherein the movable part has a first end that is pivotally supported with the base and a second end turnable around the first end with respect to the base, and wherein the drive part is arranged under the movable part to upwardly hit a bottom surface of the second end of the movable part and upwardly turn the second end of the movable part around the first end of the movable part with respect to the base.
