ABSTRACT:
A coupling includes an outer cup-shaped member which acts as a support for other portions of the coupling and which itself is revolvably supported on a conveyor that moves the coupling between workpiece loading and unloading stations. The outer cup-shaped member acts as a shield against ambient conditions which may include heating, coating or other processing means. One embodiment of the invention has a plurality of fingers mounted to move radially inward of the coupling to grasp the workpiece, which fingers are mounted to form a part of the outer shield or wall at the time that they are grasping a workpiece. Another embodiment of the invention involves an internal chuck sort of coupling using an expandable elastomeric member which can expand outwardly into a grasping relationship with a hollow portion of the workpiece. The coupling and conveyor are suited for use in handling soft or easily marked materials such as plastic, soft metals and the like.
