APPARATUS, SYSTEM AND METHOD FOR QUALITY CONTROL OF POLYMER PELLETS AND METHOD FOR CONTROLLING PRODUCTION LINE FOR PRODUCING POLYMER PELLETS

摘要

Provided is an apparatus (2) for quality control of polymer pellets，comprising at least one optical means (4,6) to record information about the appearance of at least one polymer pellet (16, 18), and control means (12), characterized in that the control means (12) are configured both to detect the presence of one or more defects in the at least one polymer pellet (16,18) and to identify the one or more detected defects， wherein identifying a defect is at least partially based on a comparison of the recorded information with one or more threshold values and/ or reference information indicative of previous recorded information of one or more pellets having such a defect, and in that the control means (12) are configured to output information about the quality of one or more detected defects, wherein the output information is indicative of the identity of the one or more detected defects．Also provided are a method for quality control of polymer pellets，a system，and a method for controlling a production line for producing polymer pellets．
