Abstract
A method for removing and transporting ophthalmic lens fabricating mold sections from a molding device to an inert chamber in a predetermined time, controlled by a central processor. The method includes starting a timer upon opening the molding device and exposing the mold sections; actuating a robotic arm to transport the mold sections from the molding device to an intermediate position using a compound movement; actuating a cam-controlled arm to transport the mold sections from the intermediate position to a pallet held on a conveyor belt at a cam-arm pre-part release location; and releasing the pallet to move on the conveyor belt to the inert chamber for continued transport of mold containing pallets to a treatment or processing facility for producing and/or packaging of the contact lenses.
