Where the Science of Quality Assurance is still an Art!
Upgrades Hole Detector Technology
Syracuse, NY, January 16, 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 by Fraser Paper Company to update its ultraviolet hole detector technology. Located in the Mid North East United States, the technology is mounted on paper manufacturing 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.
Our 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.
