ABSTRACT:
A metal ring loading and unloading apparatus is capable of loading and unloading a metal ring quickly and highly accurately for increased efficiency. The metal ring loading and unloading apparatus has a moving unit41slidably movable along a rail48which extends from a loaded ring placement unit8to an unloaded ring placement unit11. On the moving unit41, there are mounted a loaded ring delivering unit9for holding and delivering a metal ring W on the loaded ring placement unit8and an unloaded ring delivering unit10for removing the metal ring W from support rollers3, 4and delivering the metal ring W to the unloaded ring placement unit11. The loaded ring placement unit8has a pressing unit for radially pressing the metal ring W to deform the metal ring W into a substantially elliptical shape. The loaded ring delivering unit9has a loaded ring gripping unit26for gripping the metal ring W deformed by the pressing unit. The unloaded ring delivering unit10has an unloaded ring gripping unit53for gripping the metal ring W under its own recovering resiliency produced when the support rollers3, 4move toward each other. The unloaded ring placement unit11has a releasing unit for releasing the metal ring W from the unloaded ring gripping unit53.
