Leading North East Paper Maker Upgrades

R.K.B. Hole Detector Technology

 

Ultraviolet Hole Detector Technology

Syracuse, NY, February 09, 2011 - R.K.B. OPTO-ELECTRONICS, INC., a leader in providing machine vision, web inspection, splice detection and quality assurance and control technologies, has been selected to update its hole detector technology located at a leading North East United States fine  paper maker.  The technology is mounted on paper machinery just prior to the take up reel.  The hole detector inspects for critical hole defects that can commonly occur during the manufacturing process.  Our ultraviolet hole detector technology will guarantee the detection of holes down to sizes as small as 1 mm diameter.  Simple and very cost effective, the R.K.B. Ultraviolet Hole Detector Technology is the most 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 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 system will determine if a repeating hole is present and what the possible source of that repeat is.  Our 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. has pioneered the field of web inspection for paper, film, foil and allied web based materials.  Material colors, machine speed and caliper changes do not affect detection capabilities.   R.K.B. has developed and patented many of the technologies currently in use today such as infrared phototransistor technology, capacitive technology, ultraviolet technology and camera based technology.  R.K.B. was the first company to incorporate cameras as potential sensors back in the mid 1970's and patented this technique called the Vidicon 7000.  Today R.K.B. invests a majority of its finances to research and development in new sensor techniques.  Among our many innovations besides our splice detection technology, which is the world leading technology used for the detection of splices (joint), is our very successful coating streak and scratch defect detection technology.  This patented technology, now being emulated/copied, by various German inspection suppliers, detects streaks and scratches as small as 1 micron at any process speed.  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., headquartered in Syracuse, New York, has offices and partners worldwide in Asia, Europe, South America and the Middle East.
