He first describes how process data can be collected with vision sensors. Specific application examples are given. The various methods by which this process data can be integrated into an automatic control system for closed-loop feedback are discussed. Some of the application issues involved when vision sensor technology is used in the tire manufacturing environment are examined. Applications of machine vision in the tire industry can be classified as noncontact measurement, assembly verification, and product identification. Depending on the degree of process automation, the vision system can supply a simple accept/reject signal, actual results data, or an identification code. It is noted that the implementation of vision sensors has been somewhat hindered because of the harsh environment present in the tire manufacturing process. Techniques are available for dealing with these environmental concerns and must be incorporated into the system design from the beginning. It is concluded that the real benefit of machine vision is realized when the inspection data can be tied back into the machine control architecture for true automatic closed-loop process modification.<<ETX>>","PeriodicalId":405924,"journal":{"name":"Forty-First Annual Conference of Electrical Engineering Problems in the Rubber and Plastics Industries","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1989-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125240434","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The behavior of field-oriented AC drives is contrasted with that of ordinary frequency-programmed AC drives.

The gravimetric system improves quality, conserves material, and maintains a record of each extruder's material usage for inventory. By detecting and compensating for deviation in the extruder's output per screw revolution, average layer thickness and average total thickness or average tube inside diameter can be established and maintained automatically by weight. Gear pumps can help reduce short-term fluctuations to the die due to a poor screw design or high regrind levels and should be used in conjunction with gravimetric systems in some cases. The gravimetric system by itself allows for a more direct and complete extrusion control as compared to the gear pump while providing acceptable output control where short-term fluctuation is not a problem. The gravimetric system controls to an average value, thereby having a limited effect on the material distribution across the die. Prepackaged gravimetric additive feeding systems are easily incorporated to provide complete assurance and control of the materials into each extruder.<<ETX>>","PeriodicalId":405924,"journal":{"name":"Forty-First Annual Conference of Electrical Engineering Problems in the Rubber and Plastics Industries","volume":"396 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1989-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132447384","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
