R.K.B. Upgrades

Infrared Flaw Detector Technology

 

Infrared Flaw Detector Technology

Syracuse, NY, February 27, 2007 - 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 upgrade its infrared flaw detector technology located at a leading fine paper manufacturer in Asia.  Installed on paper machinery, the infrared flaw detector technology will guarantee the detection of hole and spot type defects (i.e., bugs, dirt, scale, holes) down to sizes as small as 0.8 mm diameter.  Simple and very cost effective, the R.K.B. Infrared Flaw Detector Technology, originally patented by R.K.B., is a common fixture in many web based material processes where the detection of quality defects is required. 

 

R.K.B. is pleased to have been selected as their valued supplier for high-speed defect fault detection requirements.  “Over the years, R.K.B. has provided many customers with very successful and reliable defect fault web inspection technologies.  Our partnerships have grown and will continue to grow as the need for essential and reliable quality assurance becomes more vital to ensure customers receive the highest quality and defect free product available” stated R.K.B.

 

Infrared Flaw Detector TechnologyThe R.K.B. Infrared Flaw Detector Technology offers quality inspection of web based materials for holes, dirt, scale, bugs and other visual defects at reasonable costs.  Ideally suited for installation on paper machines, coaters, laminators, slitter/winders, sheeters, and in cold rolled metals, the Infrared Flaw Detector provides high quality inspection to demanding standards.  The Infrared Flaw Detector utilizes an array of photocells located very close to the web surface at 25mm intervals cross machine direction.  The photocells monitor the intensities of infrared light transmitted through the web.  Proprietary circuitry assures uniform response and long term stability of each and every system.  The photocells are mounted on interchangeable inspection modules with each module containing a standard 6 format that covers 15.24 centimeter in the cross machine direction.  A narrow inspection aperture is implemented to effectively limit the "field of view" in the machine direction thus dramatically reducing electronic "noise" created by the web material itself.  This ensures a very high signal to noise ratio is achieved.  The aperture design also eliminate the need to mask the system, unlike European counterparts, from mill ambient light. 

 

Infrared Flaw Detector TechnologyTypically the sensing assembly is mounted on the top side of the web material perpendicular to the lamp source below the web.  Typically infrared light is transmitted through the web toward the inspection assembly.  When the photo sensors monitor a distinct change in the intensity of infrared light, an electronic output is created signaling the presence of a defect.  For the detection of holes, the system would register an increase in energy received while for spot type defects like dirt or bugs, an reduction in energy is received.  Once a defect is detected, the electronic signal is then further processed to provide type of defect, size of defect and location of defect.  The technology also provide for repeating defect analysis which is very critical in process machine maintenance and evaluation.  This analysis aids operational staff as to the defect causing problem such as wire holes, damaged fabric, slime buildup and other various conditions which reduces production, quality product and overall income per ton produced.  The Infrared Flaw Detector can be mounted on any web material process where quality assurance and control initiatives are required.

 

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.
