Method and inspection device used for the cyclic production of injection molded parts

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 of a post-cooler following removal from the injection molds by sensors including photoelectric barriers in order to recognize an error,

• wherein an inspection is carried out following a filling and an emptying of the cooling cavities of the post-cooler,
• wherein the inspection takes place row by row by the fixedly disposed sensors located in proximity to the post-cooler,
• wherein the injection-molded PET moldings are introduced into the cooling cavities of the post-cooler such that the threaded portion of the injection molded PET moldings extend out of the cooling cavities,
• wherein the sensors are fixedly disposed for each row of injection-molded PET moldings such that each of the injection molded PET moldings is moved past the sensors,
• wherein the inspection takes place row by row by the sensors with respect to the cooling cavities and the threaded portions so as to recognize the error,
• wherein the cooling cavities and the threaded portions are moved to and past the sensors in order to recognize the error,
• wherein the error includes either the absence of the injection-molded PET moldings or the retention of the injection molded PET moldings,
• wherein the case of an irregularity 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 at least one of the sensors is fixedly disposed in proximity to the injection molds such that all of the cooling cavities must pass by the at least one sensor so as to check for a position in the row,
• wherein the sensor monitoring takes place such that the threaded portions must move to and past the at least one sensor so as to recognize the error,
• wherein the error includes either an absence of the injection-molded PET molding or a retention of the injection molded PET molding,
• wherein in a case of an irregularity a safety intervention will be initiated.
