ABSTRACT:
An inverting mechanism according to the present invention comprises an inverting body for inverting which includes a plate member fixed to each of a plurality of carriers connected to an endless chain and four inverting elements rotatably supported on each plate member at circumferential positions spaced equidistant from each other, and an inverting cam provided on a rack rail on which the inverting elements roll. The inverting element on the body traveling on the rail drops into a groove formed in the inverting cam to rotate the body about the dropped inverting element as another inverting element rolls along a projection on the reversing cam to downwardly direct the top opening of the carrier and thereby an article to be transferred can be taken out of the carrier.
