Abstract

Przedmiotem zgłoszenia jest sposób obróbki drewna iglastego oraz obrobione drewno iglaste. Sposób obróbki drewna iglastego o postaci okrągłej dłużycy obejmujący segregację, przecinanie dłużycy na kłody (4), koronowanie, pozycjonowanie, przecieranie, suszenie, struganie, docinanie na długość, sztaplowanie, charakteryzuje się tym, że w procesie segregacji kłód (4) wykrywa się w nich obecność ukrytych odłamków metalowych za pomocą wykrywacza metalu (6), a każdą kłodę (4) zanieczyszczoną metalami znakuje się, zaś odseparowane kłody (4) bez wtrąceń metalicznych pozycjonuje się w optymalnej pozycji wyznaczonej za pomocą systemu detekcji optycznej zawierającej wieloczujnikowy skaner (5), następnie przeciera się na traku pionowym, po czym oddziela się materiał boczny (2) od materiału głównego (1), który poddaje się dalszemu przecieraniu metodą krzyżową, na tarcicę z otwartym rdzeniem lub z wyjęciem rdzenia (3), następnie składa w pakiety z przeznaczeniem do procesu suszenia w komorach suszarniczych i struga się za pomocą strugarki, a następnie sztapluje się tarcicę (3), za pomocą automatycznej linii do kapowania tarcicy z obustronnym prowadzeniem liniowym przycina się na odpowiednią długość, w pakiety (3). Obrobione drewno iglaste sosnowe w kształcie prostopadłościanu wytworzone sposobem według wynalazku charakteryzuje się tym, że nie posiada rdzenia lub posiada rdzeń otwarty, jego wytrzymałość na zginanie statyczne wynosi powyżej 64 MPa, zaś wartość średnia modułu sprężystości wynosi 16843 MPa, a wartość maksymalnej nasiąkliwości wynosi do 6%.The subject of the application is a method of processing coniferous wood and processed coniferous wood. A method of processing coniferous wood in the form of a round log, comprising segregation, cutting the log into logs (4), crowning, positioning, sawing, drying, planing, cutting to length, stacking, is characterized in that during the process of segregation of logs (4), the presence of hidden metal fragments is detected in them using a metal detector (6), and each log (4) contaminated with metals is marked, while the separated logs (4) without metal inclusions are positioned in an optimal position determined using an optical detection system containing a multi-sensor scanner (5), then they are sawn on a vertical frame saw, after which the side material (2) is separated from the main material (1), which is further subjected to cross-sawing, into sawn timber with an open core or with the core removed (3), then assembled into packages for the purpose of drying in drying chambers and planed using a planer, and then the sawn timber (3) is stacked, and using an automatic line for cutting sawn timber with double-sided linear guidance, it is cut to the appropriate length, into bundles (3). The processed softwood pine in the shape of a cuboid produced by the method according to the invention is characterized in that it has no core or has an open core, its static bending strength is above 64 MPa, and the average value of the modulus of elasticity is 16843 MPa, and the value of the maximum water absorption is up to 6%.
