European Converter Starts Up

R.K.B. Machine Vision Inspection Technology


Machine Vision Web Inspection Technology

R.K.B. OPTO-ELECTRONICS, INC., a leader in providing machine vision, web inspection, splice detection, edge marking and quality assurance and control technologies, has successfully started up its Model 3040 OPTOMIZER® Machine Vision Web Inspection Technology installed at a leading European Converter.  Our Model 3040 OPTOMIZER® Machine Vision Web Inspection Technology will guarantee the detection of holes down to sizes as small as 0.1 mm (0.004 inches) diameter (industry standards are 0.5mm (0.02 inches)).  Simple and very cost effective, the R.K.B. Model 3040 OPTOMIZER® Machine Vision Web Inspection Technology is becoming a more frequently used technology over complicated, high end, brand name systems that have proven to be operator unfriendly, unreliable in detection and plagued with serviceability issues and maintenance upkeep. 


The R.K.B. Model 3040 OPTOMIZER® Machine Vision Web Inspection Technology is based on using high resolution line scan CCD camera technology.  While competitive solutions all but use 2048 pixel format sensors, R.K.B. utilizes a variety of sensors depending on the application from 512 through 4096 (in some cases higher).  As a result of using a variety of CCD chip formats, R.K.B. can offer a system solution more in line with what customers are trying to achieve with their quality assurance and control R.K.B. Machine Vision Inspection Sensor; Line Scaninitiatives and guarantee the detection of defect faults required.  Similar in basic concept to all web inspection systems, the R.K.B. Model 3040 OPTOMIZER® Machine Vision Web Inspection Technology comes with an inspection assembly that generally mounts above the web material it is monitoring and perpendicular to a light source located below the web that facilitate the required energy needed for hole and flaw defect detection.  In grades that appear opaque, reflective lighting is utilized where defects other than holes are required.  As with older inspection technologies like phototransistors, the photosites contained within CCD chips collect energy and then reads that energy out to processing circuitry.  As with photocells, the increase in energy represents a hole, oil, light spot or some other type of defect that allows for the sensor to read a high energy source.  Adversely, spot type defect faults like dirt, scale, bugs will reduce the amount of energy the sensor is reading facilitating the identification of that type of defect by way of a negative pulse.  All inspection systems worldwide operate on the same basic premise. Once the defect fault has been detected, the electronic signal (initially analog as it is with all CCD sensors since the CCD chip itself is an analog device) is processed and converted to digital signals which are then further processed to facilitate defect typing, sizing and location.  All processing is done by R.K.B.'s quality assurance management system that uses, as default, Microsoft Access for information logging.  Using this database has allowed us to simplify the data logging of all events related to our machine vision technology and provided customers the capabilities of remote access by their office suite programs such as word, excel and access where custom oriented reporting functions can be derived from within.  This eliminates the need for customers to purchase specialized software reporting functions  and wasting money on tasks that firmly belong within the customers reporting structure.

As an option, R.K.B. can incorporate a defect imaging platform that provides real time and actual photos of defects stored as *.jpg format where required.  This specialized proprietary option is more accurate and reliable as a defect fault identifier since you have the capability to actually see the defect and not a made up representation of a possible defect such as offered by competitive solutions.  Additionally, our Model 3040 OPTOMIZER® Machine Vision Web Inspection Technology can be easily integrated into mill wide systems, marking units, control devices, PLC and other reporting platforms for customer traceability and use.  R.K.B. is pleased to have been selected to supply their quality assurance and control needs and are proud to have been selected as their valued supplier for their high-speed hole detection requirements.  “Over the years, R.K.B. has provided many customers with very successful and reliable defect fault inspection in a wide variety of web based materials.  Our partnerships have grown and will continue to grow as the need for essential and reliable defect fault detection becomes more vital to ensure customers receive the highest quality and defect free product available” stated R.K.B.


R.K.B. pioneered the field of web inspection for web based paper, film, foil and allied material manufacturing.  R.K.B. developed and patented many of the technologies currently in use today such as infrared phototransistor flaw detection technology, inductive and capacitive detection technology, ultraviolet phototube hole detection technology and camera based machine vision web inspection technology.  In fact, R.K.B. was the first company in the world that incorporated camera sensors for the detection of defect faults in web material in the mid 1970's and patented this technique called the VIDISCAN 7000.  Today R.K.B. invests a majority of its capital to research and development in new defect fault detection sensor techniques.  Among our many innovations besides our patented splice detection technology, which is the world leading technology used for the detection of splice (joint) tape faults, is our very successful patented Model 3020 OPTOMIZER® Coating Streak/Scratch Inspection Technology.  This technology, now being emulated and copied (badly we might add), by various European inspection solution suppliers, detects streaks and scratches as small as 1 micron (0.000039 inches (0.001 millimeter)) wide at any known process speed.  This is not only theoretical proven, but proven online at various coated paper makers worldwide.  Refer to the three studies provided herein for customer verification of the success of our streak detection technology which can be found at the following links "European Coated Board Installation", "Consolidated Papers Inc., On-line Evaluation Verification" and the comparative study done by the "American Forest Products Association in conjunction with the Institute for Paper Science and Technology".  These three vital documents were produced in a bipartisan process by each of these companies.  R.K.B. OPTO-ELECTRONICS, INC., designs, develops, manufactures, and markets the most diverse line of machine vision and web inspection technologies currently available to web based material manufacturers. R.K.B., has offices and partners worldwide in Asia, Europe, South America and the Middle East.
