R.K.B. OPTO-ELECTRONICS, INC. Hole Detector Upgraded


at an American Paper Manufacturer


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 been selected to update its Model 2084 Ultimate® Ultraviolet Hole Detector™ Technology located at a leading American fine paper manufacturer.  The Model 2084 Ultimate® Ultraviolet Hole Detector™ Technology is mounted on paper machinery just prior to the take up reel.  The Model 2084 Ultimate® Ultraviolet Hole Detector™ Technology inspects for critical hole defects that can commonly occur during the manufacturing process.  Our Model 2084 Ultimate® Ultraviolet Hole Detector™ Technology will guarantee the detection of holes down to sizes as small as 0.039 inches (1 mm) diameter up to speeds of 5000 fpm (1524 meter/min).  Simple and very cost effective, the R.K.B. Model 2084 Ultimate® Ultraviolet Hole Detector™ Technology is a commonly used hole detection device in operational today.


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 hole detection solutions and our partnerships have grown and will continue to grow as the need for essential and reliable hole detection becomes more vital to ensure customers receive the highest quality and defect free product available” stated R.K.B.


Ultraviolet Hole Detection ProcessOur Model 2084 Ultimate® Ultraviolet Hole Detector™ Technology utilizes ultraviolet light for its detection process.  A lamp housing assembly containing a line of UV Lamps is mounted on the top side of the web material allowing a narrow column of ultraviolet light that is produced to be transmitted and directed toward the sensing assembly located on the bottom side of the web material.  The web material acts as an opaque shade which prevents the passage of ultraviolet light from reaching the sensing heads located on the sensing assembly.  When a hole (void) passes by the narrow column of UV light, the light is passed on to a sensing head where the light energy is further processed.  The specially designed sensing head blocks all ambient light allowing only ultraviolet to pass through.  The sensing head, consisting of a small water tight enclosure, houses the photo sensors and processing circuitry.  A small specially designed window in each head allows ultraviolet light to pass into the enclosure through a narrow band interference filter.  This filter chemically converts the ultraviolet light to visible light that is picked up by the photo sensors and then processed.  The interference filter eliminates the "noise" created by ambient light, thus masking the entire system from mill lighting and other various sources of visible light.  Once the ultraviolet light is processed, the information is transmitted to an integrated control enclosure for further processing.  This processing then takes the electronic signal generated from the ultraviolet light and performs various algorithms such as hole defect sizing and location.  Additionally, the Model 2084 Ultimate® Ultraviolet Hole Detector™ Technology will determine if a repeating hole is present and what the possible source of that repeat is.  Our Model 2084 Ultimate® Ultraviolet Hole Detector™ Technology is generally installed just prior to take up reels and can be implemented on any line where hole defect detection is required.  R.K.B. hole detectors are found on paper machines, coating machines, slitters, winders, sheeters, cold rolled steel, aluminum lines and any other material process that required hole defect detection.


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.
