Prefabricated Class-A fire-protected mass timber building components are first sprayed or curtain-coated with clean fire inhibiting chemical (CFIC) liquid, in an automated prefabricated wood building factory environment, to provide Class-A fire-protection under the ASTM 84E test standard. Thereafter, the prefabricated Class-A fire-protected mass timber building components are sprayed or coated again with a different chemical liquid so as to provide added UV-light, moisture and termite protection to the Class-A fire-protected CLT building components. Preferably, a multi-axis robotic spray system is used for spraying CFIC liquid over all of the surfaces of the prefabricated mass timber. Machine vision systems can be used to collect video data of the spraying operations, analyzing the collected video data against preconstructed reference models, and providing guidance as required to achieve predetermined standards of quality control (QC) along the production line.

Blending apparatus for manufactured wood processing

Номер: US20200198175A1
Автор: Dan Peterson, David G. Edwall, Grant Stevenson, Mathew Fish, Shane Chucka, Wayne Temple
Принадлежит: Louisiana Pacific Corp

An improved blending apparatus for manufactured wood products with a rotating blending drum or cylinder with a pattern of alternating flights of different configurations extending from the interior of the drum. The flights lift the strands as the drum rotates to different heights before the strands free-fall back to the bottom of the drum. One flight is shorter, and may be trapezoidal in cross-section. The second flight is taller, and may have a “bull-nose” configuration with substantially vertical sides. During operation, the design of the bull-nose flight tends to hold more strands and to carry them closer to the top of the drum before the strands drop and fall. In contrast, the shorter height and angled sides of the trapezoidal flight tends to hold fewer strands and to not carry them as high along the side before strands drop and fall. The alternating pattern causes a more consistent and dispersed fall of strands as the drum rotates, resulting in a significantly larger and more consistent amount of the sprayed adhesives and waxes being applied to the strands, and not passing through gaps to build up on the drum wall.
