INTELLIGENT SINGLE POINT SENSORS
LUMBER SORTER, Thickness/Width Measurement
Many sawmills use mechanical arms or limit switches to measure
thickness at the lumber sorter. This may result in incorrectly
measured boards, or inability to distinguish between close thicknesses,
which is very important for export lumber. Improvements need to be
made to achieve more accurate measurement in situations with high
in-feed rates. Improved results need to be achieved by having exact
top and bottom board measurement.
Using SPR-02 Single Point Sensors
to accurately measure a series of thicknesses gives cross section
profiles across the width of the boards. Using an encoder will
determine the exact width of the boards. The information is then
processed by the PLC or controlling computer to classify the lumber.
The system requires (2) SPR-02 sensors, which can scan at up to 667
times per second, delivering a true picture of the board's precise
measurements. Harsh dust, temperature and vibration conditions make
the NEMA 4 rated SPR-02 sensors perfect for this application.
Improved sorting can be achieved at much higher piece rates, resulting
in increased efficiency and increased profits. Quality control
information delivered by the sensors can also detect out of range sizes.
