Abstract: This disclosure relates to a method for non-destructive inspection of a fruit (1) having an axis of rotational symmetry (10). The method comprises the step of positioning the fruit (1) in such a way that its axis of rotational symmetry (10) has an orientation that is substantially parallel to a predetermined plane (20) and the step of radiographing the fruit (1), where the direction of emission of X-rays is substantially perpendicular to said predetermined plane (20) and an X-ray image obtained (41) lies on said predetermined plane (20). The X-ray image obtained (41) is processed to calculate, at corresponding points of the X-ray image (41), respective values of attenuation of the X-ray signal through the fruit (1). The X-ray image (41) is divided into a plurality of sections (415) which are perpendicular to the projection (410) of the axis of rotational symmetry (10) on the predetermined plane (20). Each section (415) is the projection of a corresponding slice of the fruit (1) that is substantially perpendicular to the axis of rotational symmetry (10). For each section (415), the deviation between a signal attenuation trend obtained from processing the X-ray image and a reference trend, or the deviation between a trend of a local coefficient of average attenuation obtained from processing the X-ray image and a trend with constant value, is examined in order to identify any anomalies, discontinuities or variations which are indicative of respective non-uniformities in the corresponding slice of fruit. This disclosure also relates to an apparatus (9) for carrying out a non-destructive inspection of a fruit (1) having an axis of rotational symmetry (10), said apparatus being configured for implementing the method according to the disclosure.

Abstract: This invention relates to a method for non-destructive inspection of a log (1) to identify inner zones of sapwood (14) of the log (1) that have not been attacked by fungi that cause bluestain in the wood. The method comprises a first step of carrying out a tomographic scan of the log (1) to be inspected using X-ray beams that pass through the log (1) and a second step of obtaining a three-dimensional representation of the log (1) that is representative of the local moisture content of the log, the local moisture content being correlated with attenuation of the X-ray beams through the log. The method comprises the step of processing the three-dimensional representation of the log (1) to identify inner regions (145) of the log (1), in which the local moisture content is greater than or equal to a moisture threshold value for a spatial extent greater than an extent threshold. The moisture threshold value corresponds, for trees of the same species as the log (1), to a sapwood (14) with local moisture content such that it excludes the growth of fungi that cause bluestain in the wood. Each inner region (145) identified in this way is classed as a sapwood (14) zone free of bluestain. This invention also relates to a procedure for obtaining one or more wooden products from a log (1), as well as an apparatus for carrying out a non-destructive inspection of a log (1).

Abstract: A method for identifying a log of origin of a first board, comprising an identification step, during which a second board (12) is identified which was obtained from the same log (2) as the first board (11) was obtained from, a studying step, during which identifying features of the second board (12) are identified, and a recognition step during which the log (2) of origin of the first board (11) is recognised, among a plurality of known logs (2) about which saved information is available, and this is done by identifying the log of origin of the second board (12), using the identifying features of the second board (12) itself.

Abstract: A processing head (10) for a forestry machine (1) is intended to process a tree (9) having a trunk (92) with a longitudinal direction (90), branches (94) extending from the trunk (92) transversely to the longitudinal direction (90) and knots (96) extending into the trunk (92). The processing head (10) comprises: a frame (2) having a seat (20) for receiving the trunk (92) of the tree (9) to be processed; a motorised device for moving the trunk (92) relative to the seat (20), by advancing the trunk (92) through the seat (20) along the longitudinal direction (90) of the trunk (92); one or more blades (26) for cutting the branches (94) from the trunk (92) as the trunk (92) advances; a detection system for detecting positions of the branches (94) and/or of the knots (96) on the trunk (92) as the trunk (92) advances. Information on the positions of the branches (94) and/or of the knots (96) is processed to determine an identification code that is based on said positions and that refers to said trunk (92) or to a segment obtained from said trunk (92). The identification code is comparable against a code determined a posteriori for a specific trunk or for a specific segment of trunk, in order to establish whether the specific trunk or the specific segment of trunk corresponds to said trunk (92) or to said segment of trunk (92). The information on the positions of branches (94) and/or of knots (96) can also be used to determine, during a processing of the tree (9), one or more positions on the trunk (92) in which to cut the trunk (92) perpendicularly or transversely to the longitudinal direction (90), which is to say to optimise the truncation of the trunk (92).
