Abstract
An object of the present invention is to enable the orientations of chip components accommodated in groove portions of an index table to be assuredly uniformized. When a polarity judgment device finds that the orientation of the chip component accommodated in the groove portion of the index table is opposite, the polarity inversion apparatus according to the present invention moves the chip component to the component accommodating inversion portion by using compressed air and the intake air from air inlet/outlet ports. Since the bottom surface of the inlet of the inversion portion is set so as to be lower than the base surface under the index table and the width of the inlet of the inversion portion is set so as to be wider than the width of the groove portion, the chip component can move to the inversion portion without getting stuck in the vicinity of the boundary. After rotating the component accommodating inversion portion 180 degrees to change the orientation of the chip component, the compressed air and the intake air from the air inlet/outlet ports are used to return the chip component to the original groove portion. Subsequently, the inversion portion is rotated 180 degrees and the index table is rotated so that the next groove portion is opposed to the inversion portion.
