ABSTRACT:
A picker for removing articles from a remote location, including an open frame carrier secured to a molding machine for linear movement along support rods in a direction perpendicular to the direction of movement of one of the mold platens, i.e., a Y-axis direction, under control of a first fluid cylinder. The carrier, in turn, mounts a carriage for linear movement in a direction normal thereto, i.e. an X-axis direction, under the control of a second fluid cylinder. The carriage includes a third fluid cylinder for controlling linear movement in a third direction perpendicular to the first and second directions, i.e. a Z-axis direction. Depending from the carriage is a gripping unit coupled to the third cylinder, the gripping unit including a picker arm under control of a fourth fluid cylinder for movement in the X-axis direction and which picker arm terminates at its inner end in a pair of jaws or fingers, the opening and closing of which are under control of a fifth cylinder. The carriage also includes a mechanism for rotating the picker arm about the Z-axis. A limit switch is mounted on the mold machine for actuation when the movable mold platen obtains its open position. Actuation of the limit switch initiates the operation of the logic circuit, which automatically controls the operation of the picker, by operating the fluid cylinders in a predetermined sequence, thereby removing the article from a remote location and then returning the picker to its initial state.
