Abstract:

A molded parison handling apparatus for removing hollow plastic parisons used in the manufacture of oriented plastic bottles from an injection molding machine includes a base having an arm coupled to the injection molding machine. A carriage mounted on the arm moves in a first dimension into and out of the space between the molding elements of the molding machine. A frame cooling unit coupled to the carriage engages the body portion of a set of parisons as they are released from the molding machine. A first motor moves the cooling apparatus to any of three preselected positions along the first dimension located outside the molding machine. A transfer assembly includes three sets of grabbers mounted on a gantry for movement with respect to the base. One set of grabbers grabs the finish portion of the parisons from the cooling apparatus. A second and third motor then translates the transfer assembly to one of two remote locations where a stationary cooler receives the body portion of the parisons for additional cooling.
