Abstract:
1. Method for monitoring output in the cyclic and process-controlled production of injection-molded PET moldings in multi-cavity casting molds with row-by-row disposition of the injection-molded PET moldings by monitoring the handling of the injection-molded PET moldings in cooling cavities following removal of the PET moldings from the injection molds by sensors including photoelectric barriers in order to recognize an error, wherein the error includes either the absence of the injection-molded PET moldings or the retention of the injection molded PET moldings, wherein in case of the error a safety intervention is initiated, wherein the injection-molded PET moldings are introduced into the cooling cavities such that a threaded portion of the injection-molded PET moldings extends out of the cooling cavities, wherein the inspection takes place row by row by the sensors located fixedly in respect and in proximity to the injection molds, wherein the sensors are fixedly disposed for each row of injection-molded parts such that each of the injection-molded parts is moved past the sensors, wherein the cooling cavities and the threaded portion are moved to and past the sensors in order to recognize errors.
