  However, in the method for manufacturing a wood-based decorative material according to Patent Document 1, the printed pattern printed on the end surface of the wood-based board is first printed on the transfer roll. Therefore, the rule is determined according to the circumference of the outer peripheral surface of the transfer roll. A typical printed pattern is printed on the end face of the wood board. For this reason, when printing the end faces of multiple wooden boards, it is difficult to continuously print irregular print patterns or different types of print patterns on the end faces. It is difficult to give a high printing pattern.

  The present invention has been made in view of the above points, and the object of the present invention is to easily provide a printed pattern such as an irregular printed pattern or a different type of printed pattern on the end face of the wooden decorative material. An object of the present invention is to provide a method for producing a wooden decorative material having a highly designable surface that can be imparted.

  In view of the above problems, the present specification discloses the following first and second inventions. A method for manufacturing a wooden decorative material according to a first aspect of the present invention is a method for manufacturing a wooden decorative material having a printed pattern on a covering material coated on an end surface of a wooden base material, wherein the surface of the belt-shaped covering material is applied. Forming the printing surface by applying the printing pattern by inkjet printing on the surface of the coating material while conveying the coating material in the longitudinal direction of the coating material in a state of facing upward; and the printing surface The coating material conveyed along the longitudinal direction in the step of forming the sheet is continuously conveyed along the longitudinal direction, and the printing surface directed upward is oriented in the horizontal direction along the longitudinal direction. Twisting the covering material, and sticking the covering material to the end surface of the wooden board so that the printed surface faces the outside of the wooden board.

  According to the first aspect of the invention, first, a covering material to be coated on the end face of the wooden board is prepared, and the surface of the covering material is transported in an upward direction. Regular printed patterns and printed patterns such as different types of wood grain patterns can be easily applied. The covering material having such a printed pattern on the surface is twisted along the longitudinal direction so that the printing surface directed upward is directed in the horizontal direction while being conveyed along the longitudinal direction as it is. Thereby, the coating | coated material provided with the printing pattern can be easily affixed on the end surface of the wooden board | plate material of the stable attitude | position.

  Thus, in the first invention, a printing pattern is directly applied to the surface of the covering material by ink jet printing, and the covering material to which the printing pattern is applied can be continuously pasted to the end face of the wooden board. it can. In addition, even for irregularly printed patterns, printed patterns such as different types of printed patterns, etc., it is possible to easily change the printed pattern by inkjet printing, and a wood-based decorative material having a highly designable surface. Easy to manufacture. Thereby, the toning process can be abolished and an improvement in productivity can be expected. In this manner, the design can be applied to the end face of the wooden board as well as the surface of the wooden board. Furthermore, even if the color of the printed pattern to be applied to the surface of the covering material is changed for each wood-based board material, the printing pattern of the color continuously changed by ink jet printing is applied to the covering material, and this is applied to the wooden material. It can be attached to the end face of the system board.

  As a more preferable aspect of the first invention, after the attaching step, along the longitudinal direction, the step of scraping the edge of the covering material, the edge surface of the covering material exposed by scraping, The printed pattern is imparted to the edge surface and the surface of the wooden board material by inject printing so that a continuous printed pattern is formed on the surface of the wooden board material continuous on the edge surface. Process. Here, “so that a continuous printed pattern is formed” in this specification means that the printed pattern is unified as a single pattern as a whole even if the actually printed pattern is not continuous. Including the case where the printed pattern appears to be continuous.

  According to this aspect, the edge surface of the coating material is exposed by scraping off the edge of the coating material. However, since the printing pattern is given to these surfaces by inkjet printing so that a continuous printing pattern is formed on the exposed edge surface and the surface of the wood-based board material continuous thereto, the exposed edge surface Becomes inconspicuous, and the design of the wood-based decorative material can be improved.

  A method for manufacturing a wood-based decorative material according to a second aspect of the present invention is a method for manufacturing a wood-based decorative material having a printed pattern on a covering material coated on an end surface of a wood-based board material. A step of attaching the covering material, a step of arranging a plurality of wooden boards in the thickness direction so that the surface of the covering faces upward, and a stacking with respect to the plurality of wooden boards The relative movement in the thickness direction of the inkjet head between the wooden boards on both sides of the wooden board arranged in a row, and the relative movement of the inkjet head along the longitudinal direction of the wooden board. A step of applying a printing pattern by ink jet printing to a covering material adhered to a plurality of the wood-based board materials while being alternately repeated.

  According to the second aspect of the invention, the plurality of wood-based board materials are arranged so as to overlap so that the covering material stuck to the end face of the wood-based board material faces upward. The inkjet head is relatively moved along the thickness direction between the wooden boards arranged on both sides of the plurality of wooden boards in the arrangement state, and then the wooden boards A series of relative movements in which the inkjet head is relatively moved along the longitudinal direction is repeated. In this relative movement, by spraying ink from the inkjet head onto the covering material, it is possible to apply a printing pattern to the covering material adhered to the plurality of wood-based board materials simultaneously (at a time) by inkjet printing.

  Further, in the second invention, the toning process similar to the first invention can be abolished, and improvement in productivity can be expected. In this manner, the design can be applied to the end face of the wooden board as well as the surface of the wooden board. In addition, when a printed pattern is applied to the surface of the wood-based board material, productivity may be increased by increasing the number of printing equipment including an inkjet head for printing the surface separately.

  In particular, since the above-described inkjet printing is performed in accordance with the relative movement of the inkjet head between the wooden boards on both sides of the wooden boards arranged in an overlapping manner with respect to the plurality of wooden boards, more ink jet printing is performed. A printed pattern can be efficiently imparted to the wooden board.

  In addition, since the printed pattern is applied to the coating material by ink jet printing, the printed pattern corresponding to the pattern on the surface of the wooden board material or the pattern to be printed on the surface of the wooden board material from now on. It can have on the end surface of the decorative material.

Below, with reference to drawings, the manufacturing method of the wood type decorative material which concerns on embodiment of the 1st and 2nd invention is demonstrated.
[About the first invention]
The wood-based decorative material 1 according to this embodiment of the first invention is a member used for a stair tread, a flooring, a joinery, a storage door, a kitchen door, a counter, or the like, and at least a printed pattern on an end surface (a lip) Is a member to which Below, with reference to FIGS. 1-3, the manufacturing method of the wood type decorative material which concerns on 1st invention is demonstrated.

  First, in step S11 in FIG. 1, in this embodiment, a wood board 2 shown in FIG. 2A is prepared as a material to which a printing pattern is applied by inkjet printing. In the present embodiment, the wood-based board material 2 is a board material in which four projecting plates 23 are attached to the surface of a base member 21 made of a plywood having a plurality of plies. The surface 24 of the wooden board 2 has a surface on which a wood grain pattern derived from the protruding plate 23 is formed. The “woody board” in the present specification refers to a board having a wooden surface at least on a part of its surface. In the present embodiment, the four protruding plates 23 are adhered to the base member 21, but the number of protruding plates is not particularly limited as long as the surface of the base material 21 can be covered, and may be, for example, one. .

  Here, in this embodiment, the plywood is cited as an example of the wood constituting the base member 21. For example, particle board (PB), wood fiber board (MDF, insulation board, hard board, etc.), oriented strand Mention may be made of woody materials such as board (OSB), LVL, laminated wood or solid wood. As long as the rigidity and strength of the wooden decorative material 1 can be ensured, the material and thickness thereof are not particularly limited.

  Furthermore, the base member 21 is a base member made of plywood. However, the material of the base member 21 is limited as long as the protruding plate 23 can be attached to the surface and the surface of the wooden board 2 can be made the surface of wood. It is not something. For example, the base member 21 may be a composite base member in which a resin and wood are mixed, and is made of a resin such as polyvinyl chloride, polyurethane, or polyolefin resin (polyethylene, polypropylene, polyethylene vinyl acetate, polyvinyl alcohol, or the like). It may be a base member. Further, the base member 21 may be an inorganic fiber base member such as rock wool board or a carbon fiber base member made of carbon fiber.

  The veneer 23 is a veneer having a natural grain pattern derived from the veneer 23 (wood) formed on the surface thereof, and is a veneer used as a surface decorative material for making up the surface of the base member 21. As the material of the veneer, for example, beach, oak, maple, zelkova, walnut, china, oak, yachidamo, drill, cypress, cedar, mahogany, teak, rosewood, tochi, blackwood, shioji, elm, hippo, rosewood, or You can list octane. The thickness of the protruding plate 23 is preferably in the range of 0.1 to 1.0 mm.

  In the present embodiment, the veneer 23 is used as a surface decorative material having a natural wood grain pattern derived from wood on its surface. However, for example, instead of the veneer plate 23, a ground plate made of the above-described material (with a natural wood grain pattern formed on the surface) may be used as a surface decorative material for making up the surface of the base member 21. In that case, the thickness of the grinding board is preferably in the range of 1 mm to 3 mm.

  When sticking the protruding plate 23 to the base member 21, the adhesive is applied to at least one of the front surface of the base member 21 or the back surface of the protruding plate 23, and the adhesive is cured, thereby bonding the protruding plate 23 to the surface of the base member 21. To do. Of the protruding plate 23 attached to the base member 21, a portion protruding from the surface of the base member 21 is removed by trimming.

  Further, the surface of the protruding plate 23 may be colored with a colorant using a roll coater or the like before or after the protruding plate 23 is bonded to the base member 21. By performing such coloring, the wood texture of the veneer 23 can be emphasized, and the surface pattern of the wood described later can also be emphasized. Examples of the colorant include a dye colorant, a pigment colorant, and a chemical colorant.

  Next, inkjet printing is performed on the surface 31 of the covering material 3 in step S12 of FIG. First, a belt-like (tape-shaped) veneer is prepared as the covering material 3 that covers the end face 25 of the wood-based plate material 2. Examples of the material of the veneer plate that is the covering material 3 include the material of the veneer plate 23 described above, and the material of the cover material 3 is preferably the same as the material of the veneer plate 23 in order to improve the design.

  Further, the covering material 3 can be provided with a printed pattern on its surface 31 by ink jet printing, and no cracks or the like are generated even when twisted along the longitudinal direction, as will be described later. The material is not particularly limited as long as it can be attached to 25. For example, the covering material 3 may be a strip-shaped saw board, a resin tape, or a tape in which these are laminated.

  Further, a flexible reinforcing sheet such as fabric such as woven fiber or paper such as kraft paper is further laminated on the surface of the covering material 3 on the side to be adhered to the end face 25 of the wooden board 2. May be. Thereby, the intensity | strength of the coating | covering material 3 with respect to the twist along the longitudinal direction mentioned later can be raised.

  Next, as shown in FIG. 2A, the surface 31 of the covering material 3 is conveyed while the covering material 3 is conveyed in the longitudinal direction of the covering material 3 with the surface 31 of the band-shaped covering material 3 facing upward. A printing pattern is applied to the ink jet printing. The covering material 3 is sandwiched between a pair of horizontal rollers 61 and 61, and is conveyed by driving the horizontal roller 61. Thereby, as shown in FIG. 3A, a printing surface 33 by the ink layer 32 is continuously formed on the surface 31 of the covering material 3.

  Here, since the natural wood grain pattern is formed on the surface of the veneer which is the covering material 3, the natural wood grain pattern is formed while leaving the irregular shape of the surface of the veneer formed according to the natural wood grain pattern. Is preferably printed with a grain pattern different from the natural grain pattern on the surface of the veneer. Thereby, the designability can be enhanced by the printed pattern while maintaining the wood texture of the veneer of the printed covering material 3.

  More specifically, in the present embodiment, unlike the conventional technique, ultraviolet curable ink having a fine particle size is sprayed on the surface 31 of the coating material 3. Specifically, the ink droplets sprayed onto the surface 31 of the covering material 3 are preferably in the range of 1 to 20 pl, more preferably in the range of 3 to 14 pl. In this way, the uncured ink particles adhere to the surface 31 of the covering material 3 so as to be separated from each other, and a printing surface 33 in which the surface 31 is exposed from the ink particles is formed between the ink particles. Thereafter, the ink particles are cured by irradiating the printing surface 33 with ultraviolet rays.

  In the present embodiment, a printing pattern that is continuous with the printing pattern on the surface 24 of the wooden board 2 to which the coating material 3 to be described later is attached is applied to the surface of the coating material 3. Specifically, the printed pattern applied to the surface 24 of the wooden board 2 is a wood grain pattern, and the printed pattern applied to the covering material 3 is also a wood grain pattern, and both wood grain patterns are continuously formed. As such, a printed pattern is applied to these surfaces.

  In the present embodiment, the wood grain pattern formed by the ink layer 32 is obtained by photographing the surface and end face of one plate material different from the surface of the protruding plate 23 as an image, and a pattern corresponding to the photographed image (wood surface pattern). Can be obtained by printing. The wood grain pattern is printed using an inkjet printer.

  In the present embodiment, the ink of the ink jet printer is composed of, for example, four colors of yellow, magenta, cyan, and black. By using these inks, the ink layer 32 is formed on the surface 24 of the wooden board 2. Print a wood grain pattern. Here, the ink used for inkjet printing may be any of water-based ink, oil-based ink, and ultraviolet curable ink. When the covering material 3 is a projecting plate, if an ultraviolet curable ink is used as the printing ink, the printed ink is hardly impregnated in the covering material 3 and a clear surface pattern can be obtained.

  As shown in FIG. 2A, the ink jet printer includes an ink jet head 51 that contains the above-described ink and ejects each ink individually in accordance with the wood grain pattern to be printed based on the above-described image. The inkjet head 51 is disposed above the covering material 3 and can print the surface 31 facing upward of the covering material 3 by ejecting ink downward.

  Next, in step S <b> 13 of FIG. 1, the covering material 3 is attached to the end face 25 of the wooden board 2. Specifically, as shown in FIG. 2A, the covering material 3 conveyed by the pair of horizontal rollers 61 and 61 is further sandwiched between a pair of vertical rollers 62 and 62, and the covering material 3 is continuously provided. And transport along the longitudinal direction. Thus, the covering material 3 is twisted along the longitudinal direction between the pair of horizontal rollers 61 and 61 and the pair of vertical rollers 62 and 62 so that the printing surface 33 directed upward is directed in the horizontal direction (twisting). Can)

  On the other hand, as shown in FIG. 2 (a), the wooden board 2 prepared in step S11 of FIG. 1 is transported at the same transport speed as that of the covering material 3, and the end face 25 of the wooden board 2 is The adhesive roller 63 is rotated while contacting the adhesive roller 63 coated with an adhesive such as glue on the outer peripheral surface, and the adhesive is applied to the end surface 25 of the wood board 2. In the present embodiment, the adhesive is applied to the end face 25 of the wooden board 2, but for example, the adhesive may be applied to the back surface of the covering material 3.

  And the covering material 3 is conveyed at the same conveyance speed to the end surface 25 to which the adhesive agent of the wooden board | plate material 2 currently conveyed is applied, and the printing surface 33 of the coating | covering material 3 faces the outer side of the wooden board | plate material 2. The covering material 3 is adhered to the end surface 25 while pressing the covering material 3 toward the end surface 25 of the wooden board 2 with the pressing roller 65 (see FIG. 3B).

  In this way, a printing pattern is directly applied to the surface 31 of the covering material 3 by inkjet printing, and the covering material 3 to which the printing pattern is applied can be continuously pasted on the end face 25 of the wooden board 2. . As a result, as shown in FIG. 2C, the end face 15 of the wooden decorative material 1 can be printed by ink jet printing without color matching even when the printed pattern is an irregular printed pattern or a different type of printed pattern. The printed pattern can be easily changed.

  Next, in step S14 of FIG. 1, the edge portion 35 of the covering material 3 is scraped off. Specifically, after sticking the covering material 3 to the end face 25 of the wooden board 2, the wooden board 2 is conveyed along the longitudinal direction, and a pair of rotary blades 66, 66 along the longitudinal direction, The edge portion 35 of the covering material 3 protruding from the wooden board 2 is continuously scraped off. By cutting off the edge 35, the edge surface 36 of the covering 3 is exposed as shown in FIG. Here, as long as the edge portion 35 of the covering material 3 protruding from the wooden board 2 can be cut off, the cutting of the edge portion 35 of the covering material 3 is not particularly limited, such as chamfering or rounding.

  Next, in step S15 in FIG. 1, the covering material 3 is cut. Specifically, when the end 25a of the end face 25 of the wooden board 2 to which the covering material 3 is adhered moves before the end cutter 67 of the round blade, the end cutter 67 moves forward toward the covering material 3. The covering material 3 is cut by the end cutter 67. Here, the transport holes of the wood-based plate material 2 and the covering material 3 and the mechanism of the adhesive roller 63 to the end cutter 67 may be a mechanism provided in a so-called edge binder device.

  Next, in step S <b> 16 of FIG. 1, an ink jet printing process is performed on the surface 24 of the wooden board 2 and the edge surface 36 of the covering 3. Specifically, as shown in FIG. 2B, the wooden board 2 is passed below the inkjet head 52 while the wooden board 2 to which the covering material 3 is adhered is conveyed in the longitudinal direction.

  In the present embodiment, the support beam 53 is fixed along the width direction of the wooden board 2, and the inkjet head 52 is attached to be movable along the support beam 53. A printing pattern continuous by inkjet printing on the edge surface 36 of the covering material 3 and the surface 24 of the wooden board 2 continuous to the edge surface 36 while moving the inkjet head 52 in the width direction of the wood board 2 (See FIG. 3D).

  More specifically, the wooden board 2 is conveyed stepwise in the longitudinal direction, and the inkjet head 52 is moved across the width of the wooden board 2 at the timing when the conveyance of the wooden board 2 is stopped. However, the surface 24 of the wooden board 2 and the edge surface 36 of the covering 3 are printed. This series of operations is repeated. Thereby, the printing surface 28 is formed on these surfaces by the ink layer 27. In the present embodiment, the wooden board 2 is transported along the longitudinal direction. For example, when printing, the support beam 53 is moved along the longitudinal direction of the wooden board 2 to the wooden board 2. On the other hand, the inkjet head 52 may be relatively moved along the longitudinal direction.

  In this embodiment, a wood grain pattern is printed on these surfaces as a print pattern. Specifically, the wood grain pattern printed on the surface 24 of the wood-based board 2 and the edge surface 36 of the covering material 3 is formed to be continuous with the wood grain pattern printed on the surface of the covering material 3. It is. Thereby, as shown in FIG.2 (c), the surface 14 and the end surface 15 of the manufactured wood type decorative material 1 have a grain pattern like a board material (solid material) cut out from one piece of wood. Become.

  Here, a natural wood grain pattern is formed on the surface of the projecting plate 23, which is the surface 24 of the wood-based board material 2, in the same manner as the printing of the covering material 3. Therefore, the natural wood grain pattern is formed according to the natural wood grain pattern. It is preferable to print a wood grain pattern different from the natural wood grain pattern on the surface of the veneer so that the natural wood grain pattern can be visually recognized while leaving the uneven shape on the surface of the veneer board. Thereby, the wood texture of the veneer can be maintained on the surface 24 of the printed wooden board 2.

  Furthermore, the wood grain pattern printed on the surface 24 of the wood-based board 2 and the surface 31 of the covering material 3 is not good as a conventional wood pattern, cracks, wrinkles, perforations, bar, sugar Patterns unique to wood, such as streaks, false cores, verticals, uneven color, and patterns of edges, may be included. Furthermore, a saw mark pattern (rafthorn) formed when the wood is cut and processed, and a nail hole mark pattern may be included. Thereby, it can be used in combination with natural wood having a pattern similar to these printed patterns without a sense of incongruity.

  In the present embodiment, the edge surface 36 of the covering material 3 is exposed by scraping off the edge 35 of the covering material 3 in step S14. However, the exposed edge surface 36 and the continuous surface 24 of the wood-based board 2 are provided with a grain pattern on these surfaces so that a continuous printed pattern is formed. 36 becomes inconspicuous, and the designability of the wooden decorative material 1 can be enhanced.

[About the second invention]
Below, with reference to FIGS. 4-6, the manufacturing method of the wood type decorative material 1 which concerns on embodiment of 2nd invention is demonstrated.

A print pattern is applied (see FIG. 6C). Thereby, the printing surface 33 is formed on the surface 31 of the covering material 3 by the ink layer 32.

  More specifically, the wooden board 2 is conveyed stepwise in the longitudinal direction, and the inkjet head 55 is moved across the width of the wooden board 2 at the timing when the conveyance of the wooden board 2 is stopped. However, the surface 31 of the covering material 3 is printed. This series of operations is repeated. Thereby, the printing surface 33 is formed on the surface 31 of the covering material 3 by the ink layer 32. In this embodiment, the wooden board 2 is conveyed along the longitudinal direction. However, for example, by moving the support beam 56 along the longitudinal direction of the wooden board 2 during printing, the wooden board 2 is moved to the wooden board 2. On the other hand, the inkjet head 52 may be relatively moved along the longitudinal direction.

  Thus, since printing was performed in a state in which the wood-based board materials 2 were superposed and arranged, a printing pattern was given simultaneously (at a time) to the covering material 3 adhered to the end face 25 of the plurality of wood-based board materials 2. can do. In the present embodiment, the printed pattern applied to the surface 31 of the covering material 3 is a wood grain pattern as in the case described in the first invention.
