Economical interest of a X-rays vision system in a planing mill production chain

Abstract

This presentation is the first phase of a more complete study about the interest of the use of an X-ray scanner in the context of a planing mill. This scanner, placed upstream to edging phases of concerned wood products (unedged timber, square edged timber), allows to make visible not perceptible defect of the material by the human operator eye. These new knowledge in correlation with rough materials has to allow an improvement of the valuation of the end products, but also has to indicate the improvement tracks of the production installation. Our first tries aim at validating this hypothesis.

“…The currently used optimization systems (such as MiCROTEC, LuxScan, WoodTech, LMI, and WoodInspektor) are based on fault identification and their acceptability for the various sizes and grades of prefabricated products. Only some of the models, mainly those focused on the maximization of the yield of principal product and minimization of byproducts, will provide the desired output (Almecija et al 2013;Rummukainen et al 2018;Belley et al 2019).…”
