With LIMAB non contact laser measurement system it's possible to nearly anywhere in production measure thickness, width and length of wood pieces. Measurement is done automatically, under lengthwise movement, in one or more measuring tracks with 1/10 of a mm accuracy. Length is measured by means of counting pulses from an encoder giving an accuracy of typically +-10mm, depending on mechanical conveyor conditions. On the system PC alarm limits for upper and lower values can easily be keyed in. One can also specify max allowed extension for out of spec condition before alarm output activates. This means that the operator immediately gets alerted when a board is e.g. to thin and should not be glued. The software displays the profile of each board graphically. Each production batch is statistically evaluated, the result telling how many pieces are ok, to thin, to narrow, to short and so on. In a dimensional table all products with specific data can easily be keyed in and then chosen for each new run. Data can continuously, and/or after every batch be transferred to external PLC or control system.
