<p>A transfer apparatus 10 includes crank arms 22 each of which is pivotally attached to a driving wheel 21, link levers 23 each of which has its one end pin-linked to the tip of the crank arm 22, and revolving sections 30 each of which is pin-linked to the other end of the link lever 23 and held at a distance from the rotation axis 210 of the driving wheel 21, wherein: the crank arm 22 is provided with a velocity-changing cam roller 223 protruding therefrom at a position spaced apart from the pivot center thereof; the velocity-changing cam roller 223 is guided while being engaged with the velocity-changing cam groove 44 which is formed to be eccentric to the rotation axis 210 of the driving wheel 21, whereby the tip of the crank arm 22 swings during one complete rotation of the driving wheel 21; and, as a result, the angular velocity of the link lever 23 linked to the tip of the crank arm 22 and the revolving section 30 periodically increases/decreases with respect to the angular velocity of the driving wheel 21. <IMAGE></p> |
