Embodiment approach 1

[0042] figure 1 It is a flowchart showing the outline of the process of the manufacturing method of the compressed wood product in Embodiment 1 of this invention. First, a blank in a predetermined shape is selected from logs (step S1). figure 2 It is a figure which schematically shows the outline|summary of a sampling process. In the material extraction process, a substantially disc-shaped blank 2 is selected from a log 1 such as a solid material in an uncompressed state by cutting or the like. Log 1 Choose the best raw material from cypress, luohan cypress, sycamore, fir, pine, cherry, beech, ebony, rosewood, bamboo, teak, mahogany, rosewood, etc.

[0043] The blank 2 has: a flat plate-shaped main plate portion 2a having a substantially rectangular surface; two side plate portions 2b extending curvedly from two long side portions opposed to the surface of the main plate portion 2a respectively relative to the main plate portion 2a; There are two side plate portions 2c, wh...

Embodiment approach 2

[0066] The second embodiment of the present invention is characterized in that a plurality of flat-shaped compressed wood products are produced from a flat-shaped blank. The processing flow of the manufacturing method of the compressed wood product of the present embodiment 2 is the same as that of the above-mentioned embodiment 1 (refer to figure 1 ).

[0067] Figure 13 It is a figure which shows the structure of a pair of mold and blank used in the compression process (step S3). Figure 14 is along Figure 13 Sectional view of the B-B line. The mold 15 that applies a compressive force from above the flat blank 8 is a core mold having a convex portion 151 . Protruding portions 152 protruding linearly along the longitudinal direction are formed at regular intervals in the lateral direction on the convex portion 151 . The mold 16 that applies compressive force from below the blank 8 is a cavity mold having a concave portion 161 . The concave portion 161 has a plurality o...

Embodiment approach 3

[0076] Embodiment 3 of the present invention is characterized in that, by providing protrusions on the blank side, the density of the region corresponding to the boundary of the plurality of parts is higher than that of other regions. The processing flow of the manufacturing method of the compressed wood product of the present embodiment 3 is the same as that of the above-mentioned embodiment 1 (refer to figure 1 ).

[0077] Figure 17 It is a figure which shows the structure of a blank, and shows the structure of a pair of dies used in a compression process. Figure 18 is along Figure 17 Sectional view of line C-C.

[0078] The blank 21 is substantially bowl-shaped like the blank 2, and has a main plate part 21a, two side plate parts 21b, and two side plate parts 21c. On the outer surface from the main plate portion 21a to the side plate portion 21b, a first protrusion portion 211 protruding linearly along the short side direction is provided. Further, a second protrudi...

Abstract

Provided is a method of producing a compressed wood product wherein moisture is prevented from infiltrating into the end face of a wood which is cut after compression without increasing the man-hours. The method comprises a compression step for applying a compressive force to a blank material (2) of a predetermined shape blocked from a raw wood while clamping the blank material by a pair of dies (11, 12), and a division step for dividing the blank material (3) compressed in the compression step into a plurality of portions by cutting, wherein the compressibility in the compression step of a region corresponding to the boundary of the plurality of portions (4, 5) of the blank material (3) divided in the division step is higher than the compressibility in the compression step of other regions of the blank material, and the width of the boundary is larger than the cutting width when the blank material is cut in the division step.

Description

technical field [0001] The present invention relates to a method of manufacturing compressed wood products by compression forming wood into a predetermined three-dimensional shape. Background technique [0002] In recent years, wood as a natural raw material has attracted attention. Since wood has various grains, individual differences occur depending on the parts selected from the raw wood, and this individual difference becomes the individuality of each product. In addition, blemishes or changes in color tone due to long-term use also become a unique style, which may be familiar to users. For these reasons, wood has attracted attention as a raw material that can create individuality and taste that cannot be found in products using synthetic resins or light metals, and its molding technology has also made great progress. [0003] Conventionally, as such a technique for forming wood, there is known a technique of compressing a piece of wood softened by absorbing water, cut...
