Description

  The present invention relates to a method for producing a decorative material used for a fence, a step board, a skirting board, a door and the like in a building such as a house.

  For some time, decorative materials used for eaves, footboards, skirting boards, doors, etc. in buildings of various forms such as houses have been developed. For example, Patent Document 1 discloses as shown in FIG. In addition, a flexible sheet 2 such as a non-woven fabric or synthetic resin sheet made of polyester or the like is pasted on the surface of a single sheet material 1, and the natural wood is thinned on the surface of the flexible sheet 2. While sticking the projected plate etc. as the surface material 3, the bottom is V toward the flexible sheet 2 from the back surface of the plate material 1 (the surface opposite to the surface on which the flexible sheet 2 or the like is adhered). A decorative material 5 (before bending) in which a letter-shaped cutout groove 4 is formed is disclosed.

  Then, as shown in FIG. 11 (b), the decorative sheet 5 is formed by bending the flexible sheet 2 as a guide so as to close the notch groove 4. Further, a bar-shaped material as shown in FIG. 12 is formed by forming a notch groove 4 having a complicated shape and performing a bending process.

Japanese Utility Model Publication No. 54-109317

  However, since the decorative material 5 of the prior art performs the bending process including the flexible sheet 2 and the surface material 3, the surface material 3 is flexible enough to withstand the bending process. There was a problem that the material had to be selected and the range of material selection was narrow.

  In recent years, the supply of large-diameter trees has decreased, and it has become difficult to supply a single wood veneer veneer, so if the design (surface pattern) of the top and side surfaces is different, like a kite. In such a case, for example, a plate material 1 having a surface material 3 provided with a surface material 3 (printing sheet, protruding plate, etc.) of a different design (surface pattern) adjacent to the surface side is prepared. From the back side, the cutting edge of the V-groove cutting rotary saw is precisely aligned with the boundary line of the design from the back side, leaving the surface material 3 to form the notch groove 4 from the back side, and then bending at the notch groove 4 It had to be manufactured in such a way as to adhere. However, it has been very time-consuming to accurately match the tip of the V-groove cutting tool with the boundary line of the design from the back side to the front side, resulting in a problem of reducing productivity.

  In addition, since the V-cut is made to the single plate material 1, both sides of the cutout groove 4 are naturally the same plate thickness. For example, in response to a request to change the plate thickness between the top surface and the side surface. There was no way to change the thickness on both sides of the notch groove 4.

  The present invention has been developed in view of such problems of the prior art. Therefore, a main object of the present invention is to provide a method for manufacturing a cosmetic material that can be selected and made different in surface pattern and material on both sides of a corner with good productivity.

  When the side surfaces 12a and 14a of the two plate members 12 and 14 are brought into contact with each other, if there is a foreign object such as foreign matter between the two side surfaces 12a and 14a, the surfaces of the two plate members 12 and 14 do not come into contact with each other correctly (i.e., spaced apart). However, according to the present invention, the V-shaped groove 20 is formed in a state where the V-shaped groove 20 is formed and the productivity is reduced. Since the taper surface 60 that forms an acute angle with the surface of the plate material 12 is formed, even when foreign matter or the like is present between the side surfaces 12a and 14a of the both plate materials 12 and 14, the two plate materials 12 and 14 are brought into contact with each other. By letting out the foreign matter or the like, the surfaces of both plate members 12 and 14 can be brought into contact with each other accurately, and the production yield can be dramatically improved by suppressing the occurrence of defects.

The invention described in claim 6 relates to an improvement in the method for manufacturing the decorative material 10 according to any one of claims 1 to 5,
“After the side surface 12a of the first plate member 12 and the side surface 14a of the second plate member 14 are brought into contact with each other, the groove 20 formed on the contact surface 22 of the both plate members 12 and 14 is closed. ,
A tape material 28 having flexibility is applied to the surface from the first plate material 12 to the second plate material 14,
After the two plate members 12, 14 are fixed to each other, the tape member 28 is peeled off. "

  According to the present invention, when the tape material 28 is bent as a guide, a pressing force is generated in the stretched portion of the tape material 28 in a direction in which the surface side ends of the bent portions are brought into close contact with each other. In particular, it is more effective when the V-shaped groove 20 reaches the surface and the tips of the plate members 12 and 14 are thinned. The tape material 28 also has a role of preventing the adhesive 36 attached to the groove 20 from protruding to the surface. In this way, by using the tape material 28, it is possible to manufacture the cosmetic material 10 having a good appearance in which the end portions of the plate materials 12 and 14 are accurately matched.

The invention described in claim 7 relates to an improvement of the manufacturing method of the decorative material 10 described in claim 6,
“Attaching the tape material 28 is performed in a state where the surface of the first plate material 12 and the surface of the second plate material 14 in contact with each other form an obtuse angle,
After affixing the tape material 28, the grooves 20, 30, 32 are formed after the plate material 12, 14 is expanded so that the contact angle between the two plate materials 12, 14 becomes larger. "

  According to the present invention, the surface of the first plate member 12 and the surface of the second plate member 14 are attached to the surfaces of the two plate members 12 and 14 in an obtuse angle (an angle larger than 90 degrees and smaller than 180 degrees). The tape material 28 has a force to shrink when both the plate materials 12 and 14 are extended and extended so that the contact angle between the both plate materials 12 and 14 becomes larger. Since both the board | plate materials 12 and 14 are pressed more strongly by this contraction force, the front-end | tip parts of both the board | plate materials 12 and 14 correspond more accurately, and the cosmetics 10 with a more attractive appearance can be manufactured.

The invention described in claim 8 relates to an improvement in the method for manufacturing the decorative material 10 according to claim 2 or 4,
“The first plate member 12 and the second plate member 14 have a desired surface pattern by ink jet printing on paper having an ink receiving layer that is attached to the surfaces of the base members 13 and 15 in advance as the surface members 18a and 18b. It is formed ".

The invention described in claim 9 relates to an improvement in the manufacturing method of the decorative material 10 according to claim 8,
“A transparent paint is applied to the surface of the ink-jet printed paper”.

  A general printing sheet requires printing lots of thousands to tens of thousands of meters printed on a rotary press. If it is used for products with large areas such as wall materials and flooring, there is no problem even if the printing lot is large in this way, but cosmetics with a small construction area such as fences, treads, baseboards, etc. In the case of using a printing sheet for a large number of printing lots, it was not possible to prepare many kinds of surface patterns and there was no freedom of selection. In particular, since the pattern used for the chamfered portion 34 has a small amount of use, the above-mentioned problem of the printing lot is remarkable.

  However, in the invention described in claim 8, since the decorative patterns of the surface materials 18a and 18b can be printed in a smaller area (for example, in units of 3 × 6 plates) using ink jet printing, various types of surface patterns can be printed. Even if it is prepared, there is little inventory risk and it is possible to design a product with a high degree of freedom.

  In addition, when the surface materials 18a and 18b on which the decorative pattern is formed are pasted on both the base materials 13 and 15, curing is required until the adhesive for pasting the surface materials is solidified. There was a problem that productivity was never improved.

  However, since the paper having the ink receiving layer is pasted and integrated on the surfaces of the base materials 13 and 15 in advance and printing is performed as necessary, the curing period as described above becomes unnecessary, so that the short delivery time Makes it possible to produce cosmetics.

  Ink jet printing may be performed using a facility capable of printing on a general thick plate, and it is preferable to use UV colored ink having excellent water resistance.

  Further, as described in claim 9, immediately after ink jet printing, a transparent paint is applied to the surface of ink jet printing (undercoating), thereby transporting when applying a tape or grooving in a later step. It can prevent the damage by.

  As such a transparent paint, a general paint for acrylic, urethane or the like is used, but an undercoat containing a so-called antifriction agent such as white alumina or green carbon is preferably used. Needless to say, the surface of the undercoated transparent coating may be further coated with a transparent coating (overcoating) so as to erase the scratches generated during transportation.

  Of course, as the surface material 18, DAP-impregnated paper, melamine-impregnated paper, or the like may be provided on the surfaces of the base materials 13 and 15 without providing the adhesive layer 16. Further, a thermosetting resin-impregnated decorative paper having poor flexibility can be used as the surface material 18.

  Next, using the first plate material 12 and the second plate material 14 described above, the tape material 28 including the case where the surface material 18 is not used, centering on the “decorative material 10 having the surface material 18”, which is a finished product. A procedure for manufacturing without using will be described.

  First, a first plate member 12 and a second plate member 14 provided with surface members 18a and 18b having different surface patterns are prepared via an adhesive layer 16 (FIG. 1A), and the surfaces of the plate members 12 and 14 are prepared. The side surface 12a of the first plate member 12 and the side surface 14a of the second plate member 14 are abutted and brought into contact with each other (FIG. 1B).

  After the plate members 12 and 14 are brought into contact with each other, the cutting edge of a V-shaped rotary saw (not shown) is brought into alignment with the contact surface 22 appearing on the back surfaces of the plate members 12 and 14 while maintaining the contact state. After that, it is cut out with a rotary saw to form a V-shaped groove 20 that matches the shape of the rotary saw (FIG. 1C).

  As a means for maintaining this contact state, a method of completely fixing both plate members 12 and 14 can be considered. By fixing means such as a method of mechanically fixing with a clamp, a pressing machine, a large saw-like fixing tool (so-called gang), air adsorption, an adsorbent having an adsorbent on the surface, an adhesive having an adhesive on the surface, etc. The method of fixing is mentioned. When using a transporter that may damage the surface of the plate material, such as an escape, it is preferable to contact the escape with the back side.

  Further, in order to cope with various width dimensions and thickness dimensions, it is desirable to suppress horizontal and vertical lifting using an air damper, an oil damper, a spring cushion, or the like. When using a horizontal pressing force, both plate members 12 and 14 may be urged against each other, and a side surface opposite to the contact side surface of one plate material is a so-called ruler surface, The urging contact may be made by pressing.

  Furthermore, it is also possible to carry out grooving by conveying both plate members 12 and 14 while maintaining a contact state with a fixed rotary saw. In this case, a method of conveying while mechanically abutting with a clamp, a pressing machine, an escaper, etc., a method of conveying while abutting with a fixing means such as air adsorption, an adsorber, an adhesive, or the like, For example, a method may be used in which an air damper, an oil damper, a spring cushion, or the like is used to convey 14 while being urged against the ruler surface as described above.

  In any case, in order to improve the groove machining accuracy, it is preferable to eliminate vertical blur due to cutting using a vertical pressing force. In this case, it is preferable to press the position as close as possible to the portion to be cut in order to improve the groove processing accuracy.

  The groove 20 has a groove bottom portion 20a coinciding with the contact surface 22 and reaches the surfaces of the base materials 13 and 15 constituting both plate members 12 and 14 or near the front thereof (therefore, in this case). Is formed so as to reach the surface of the surface material 18 (that is, the surface of the both plate materials 12 and 14) or near the front of the surface material 18 (that is, the surface of the surface material 18 is not cut). Therefore, in this case, the butt end portions of the surface materials 18 of both the plate materials 12 and 14 are cut and thinned. The groove 20 is cut into a shape that matches the shape of the rotary saw.

  The groove processing described above may be performed by fixing both plate members 12 and 14 in a contact state and moving the rotary saw, or conversely, rotating the rotary saw and rotating both plate members 12 and 14 in contact. You may make it carry out by moving in a state.

  The reason why the position of the groove bottom portion 20a is "the surface of both plate members 12, 14 or in the vicinity thereof" is to prevent the position of the groove bottom portion 20a of the groove 20 from protruding from the surfaces of both plate members 12, 14. In consideration of the accuracy of groove processing (about ± 0.03 mm), it is preferable to set the position to a position slightly behind the front surfaces of both plate members 12 and 14.

  Further, by forming the groove 20 into a “V-shaped groove” by a single process using a rotary saw whose tip is formed in a V shape (in this embodiment, a 45 ° saw blade with a single blade). The angle of the inclined surface to be formed can be made accurate, and when the two plate members 12 and 14 are joined, a beautiful joining without a gap or the like is possible at the joining portion. Of course, a so-called router machine or the like may be used instead of the rotary saw.

  Leave both plate members 12 and 14 in contact with each other (at this stage, if the surface member 18 is not used, the surface side ends of the two plate members 12 and 14 or the surface member 18 as shown in the figure. When used, the surface materials 18 are in contact with each other.), Hot melt adhesive, PUR hot melt adhesive, aqueous vinyl urethane adhesive, vinyl acetate adhesive on the surface of the groove 20 Alternatively, an adhesive 36 such as a urethane adhesive is attached (FIG. 1D), and then the groove 20 is closed and the two plate members 12 and 14 are fixed to each other to complete the decorative material 10 ( FIG. 1 (e)).

  The adhesive 36 may be attached to both surfaces of the groove 20 in the both plate members 12 and 14, or may be attached to only one surface of the groove 20.

  In addition, since both the plate members 12 and 14 are configured as separate members, when the decorative material 10 is formed by fixing them, the corner portion 26 of the decorative material 10 (of the mating surface with the groove 20 closed) is formed. There is a possibility that the adhesive 36 protrudes from the surface side edge). In such a case, the adhesive 36 has the same color as or similar to the surface color of the base materials 13 and 15 (when the surface material 18 is not attached) and the surface color of the surface material 18 (when the surface material 18 is attached). By coloring in color, the protruding adhesive 36 is less noticeable, which is preferable.

  A plurality of types of adhesives 36 may be used in combination. For example, water-based vinyl urethane adhesives are excellent in adhesive strength but require a little time to cure, so although they are slightly inferior in adhesive strength, PUR hot-melt adhesives and water-based vinyl urethane are quick in time to cure. In combination with an adhesive, both plate members 12 and 14 are first fixed with a PUR hot melt adhesive to prevent undesired displacement and the like. Is cured, the two plate members 12 and 14 can be firmly bonded without being displaced.

  Since the first plate member 12 and the second plate member 14 are separate members as described above, the surface patterns (designs) of the plate members 12 and 14 used for one surface and the other surface sandwiching the corner portion 26. ) And materials (hardness, plate thickness, etc.) can be made different from each other. In addition, when the surface material 18 having a different surface pattern is used for each of the base materials 13 and 15, a material having poor flexibility can be used as the surface material 18.

  As shown in FIG. 2, at a stage before the first and second plate members 12 and 14 are brought into contact with each other, at least one side surface of both plate members 12 and 14 (in this embodiment, the side surface 12 a of the first plate member 12). In addition, a tapered surface 60 that forms an acute angle with the surface of the first plate member 12 may be formed. The acute angle formed by the surface of the first plate 12 and the tapered surface 60 is larger than the angle (acute angle) formed by the surface of the first plate 12 and the surface formed by the V-shaped groove 20 formed later. In addition, when forming the taper surface 60, the surface side of both board | plate materials 12 and 14 will be arrange | positioned downward so that it may show in figure.

  When the side surfaces 12a and 14a of the two plate members 12 and 14 are brought into contact with each other, if there is a foreign object such as foreign matter between the two side surfaces 12a and 14a, the surfaces of the two plate members 12 and 14 do not come into contact with each other correctly (i.e., spaced apart). In this state, the V-shaped groove 20 is formed and a defect occurs, resulting in a decrease in productivity. However, by forming the tapered surface 60 as described above, Even if there is a foreign object or the like between the side surfaces 12a and 14a, the surfaces of the two plate materials 12 and 14 can be brought into contact with each other accurately by releasing the foreign material or the like when the two plate materials 12 and 14 are brought into contact with each other. It is possible to suppress the occurrence of defects and dramatically improve the production yield.

  Further, as shown in FIG. 5, the side surface 12 b opposite to the side surface 12 a on which the tapered surface 60 is formed in the first plate material 12 is formed on the ruler surface 62, and the first plate material 12 and the second plate material are formed. When contacting 14, the side surface 14 a of the second plate member 14 may be pressed against the side surface 12 a formed with the tapered surface 60 in the first plate member 12 positioned with reference to the ruler surface 62.

  Thereby, since the 2nd board | plate material 14 can be correctly contacted with respect to the 1st board | plate material 12 positioned correctly on the basis of the ruler surface 62, generation | occurrence | production of a defect can be suppressed and a production yield can be improved further. it can.

  Next, the case where it manufactures using the tape material 28 is demonstrated. As shown in FIG. 3, the tape material 28 which has flexibility is affixed on the surface of both board | plate materials 12 and 14 in the state which mutually contact | abutted the side surfaces 12a and 14a of both board | plate materials 12 and 14, and was flush | planar ( 3 (b)), the groove is processed in the same manner as described above (FIG. 3 (c)), and after the adhesive 36 is attached to the groove 20 (FIG. 3 (d)), the tape material 28 is bent as a guide. The two plate members 12 and 14 are fixed to each other, and finally the tape material 28 is peeled off (FIG. 3E).

  Note that the tape material 28 may be applied at any time from the time when the plate members 12 and 14 are brought into contact with each other until the groove 20 formed in the contact surface 22 is closed. Moreover, you may use together forming the taper surface 60 in the at least one side surface 12a in the side surfaces 12a and 14a of the 1st and 2nd board | plate materials 12 and 14 mentioned above.

  The tape material 28 is made of vinyl as long as it is a general thin tape having an adhesive strength that does not peel off from both the base materials 13 and 15 or the surface material 18 between the time when the tape material is applied and the time when the bending process is completed. Any material can be used regardless of whether it is made of paper or paper. However, if the adhesive strength of the tape material 28 is too strong, the surface material 18 will be peeled off when the tape material 28 is peeled off. When using 18, it should be noted that a tape material with excessively strong adhesive strength should not be used. Therefore, what is used for the purpose of peeling after sticking is preferable, and a so-called curing tape is most preferably used. Curing tape is a tape used for temporary fixing in construction or the like, and is a tape intended to be peeled off after being stuck for a certain period. For this reason, the adhesive tape is designed to be less likely to remain on the adherend, and is most suitable for use in the present production method. In addition, the general curing tape is considered to be easy to cut in the length direction and have strength in the width direction by making the cutting strength in the transverse direction significantly weaker than that in the length direction. When used in this production method, the contact strength between the plate materials can be ensured, and the transverse cut can be easily performed at the time of attachment. Such a method for producing a curing tape is disclosed in, for example, JP-A-58-52380 and JP-A-5-247421.

  In this way, by bending the flexible tape material 28 attached to the surface from the first plate material 12 to the second plate material 14, the end portions of the side surfaces 12a and 14a of the two plate materials 12 and 14 contact each other. It can be adhered and fixed while maintaining the contact state. At this time, as already described, accurate tip contact is performed by the pressing force generated at the portion of the tape material 28 that is bent at the bent portion. In particular, it is more effective when the V-shaped groove 20 reaches the surface and the tips of both plate members 12 and 14 are thinned. The tape material 28 also has a role of preventing the adhesive 36 attached to the groove 20 from protruding to the surface. As described above, by using the tape material 28, it is possible to manufacture the cosmetic material 10 having a good appearance in which the end portions of both the plate materials 12 and 14 are accurately matched.

  Moreover, as shown in FIG. 4, you may set so that the thickness of the 1st board | plate material 12 and the thickness of the 2nd board | plate material 14 may mutually differ.

  Furthermore, as shown in FIG. 5, the surface of the 1st board | plate material 12 and the surface of the 2nd board | plate material 14 which were contact | abutted mutually means an obtuse angle (an angle larger than 90 degree | times and smaller than 180 degree | times. The tape material 28 described above is applied in a state where the tape material 28 is formed (FIG. 5 (b)). After the material 28 is pasted, the groove 20 may be formed after spreading so that the contact angle between the two plate materials 12 and 14 becomes larger (FIG. 5C).

  As a result, the two plate members 12 and 14 come into contact with the tape member 28 attached to the surfaces of the two plate members 12 and 14 in a state where the surface of the first plate member 12 and the surface of the second plate member 14 form an obtuse angle. When both plate members 12 and 14 are expanded so that the angle becomes larger (preferably the angle between the surface of the first plate member 12 and the surface of the second plate member 14 is 180 degrees). The force to try to shrink arises. Since both the board | plate materials 12 and 14 are pressed more strongly by this contraction force, the front-end | tip parts of both the board | plate materials 12 and 14 correspond more accurately, and the cosmetics 10 with a more attractive appearance can be manufactured.

(Second embodiment)
A second embodiment will be described with reference to FIG. The first embodiment described above and the second embodiment basically use a wood fiber base material for either one of the base materials 13 and 15 constituting the both plate materials 12 and 14. And only the difference in the number of grooves to be formed will be described with reference to the description of the first embodiment for the common parts with the first embodiment in the description of the second embodiment. Omitted, the description will focus on the differences.

  As described above, at least one of the first base material 13 and the second base material 15 constituting the first plate material 12 and the second plate material 14 of the present embodiment has a wood fiber base material (medium specific gravity fiber plate, High specific gravity fiber boards, dry-molded wood fiber boards such as MDF and HDF, and wet paper-made wood fiber boards such as hard boards are used. Hereinafter, the case where the first base material 13 is a wood fiber base material will be described as an example. It should be noted that the surface handle of the first plate member 12 and the second plate member 14 (when the surface member 18 is not used, the surface handle of the first base member 13 and the second substrate 15 and the surface member 18 are used first. Needless to say, the surface material 18a attached to the base material 13 and the surface material 18b attached to the second base material 15 are set to be different from each other.

  With the surfaces of the first plate member 12 and the second plate member 14 being flush with each other, the side surface 12a of the first plate member 12 and the side surface 14a of the second plate member 14 opposed thereto are brought into contact with each other. While maintaining the contact state, with the groove bottom 30a coinciding with the contact surfaces 22 of the two plate members 12 and 14, the V-shaped first ends extending from the rear surface to the front surfaces of the two plate members 12 and 14 or near the front thereof. One groove 30 is formed. At the same time as the formation of the first groove 30 or before and after the formation of the first groove 30, another V-shaped second groove 32 adjacent to the first groove 30 is provided as the wood fiber base material of the first plate 12. (= First substrate 13).

  As a result, a chamfered portion 34 having a right triangle shape is formed at the abutting end portion of the wood fiber base material (= first base material 13).

  In the illustrated embodiment, the first groove 30 is a “single V-shaped groove (the main groove) formed by cutting only the first plate 12 side with the contact surface 22 between the first plate 12 and the second plate 14 as a boundary. In the embodiment, the second plate member 14 is formed as a triangle having a right-angled corner on the back side, and the second groove 32 is similarly inclined toward the contact surface 22 with the second plate member 14, and In addition, a “single V-shaped groove” in which the corner on the opposite side is a right angle is formed symmetrically adjacent to the first groove 30. In addition, in the chamfered portion 34 of the present embodiment, the lengths of the two sides 34a and 34b that are orthogonal to each other in the sectional view correspond to the heights of the side surfaces 12a and 14a in the first and second plate members 12 and 14, respectively. As shown in FIG. 6 (e), when the bending process is performed, the inner edge of the corner portion 26 becomes a right angle, so that it can be attached to the surface of the quadrangular prism material. The possible decorative material 10 can be formed. (Of course, as shown in FIG. 7, the lengths of the sides 34a and 34b may be longer than the heights of the side surfaces 12a and 14a, or conversely, may be shortened.)

  When receiving a stress from a cutting tool for grooving when forming a substantially triangular chamfered portion 34, “a mating surface of an annual ring or a conduit port” such as solid wood, plywood, or particle board (in the case of solid wood) ), “The mating surface between the plate materials” (in the case of plywood), or “the mating surface between the granular materials” (in the case of particle board), the tip portion of the chamfer 34 is skipped from the “directional boundary”. However, according to the manufacturing method of the decorative material 10 according to the present embodiment, the chamfered portion 34 is formed on the wood fiber base material (= first base material 13), and the wood fiber base material. Is formed so that the fibers are intertwined in a complicated manner and has no directionality (non-directionality), it is possible to eliminate the possibility that the chamfered portion 34 is skipped.

  In addition, the above-described groove processing method (whether both plate members 12, 14 are moved or the rotary saw is moved), and the positions of the groove bottom portions 30a, 32a are "the surface of each plate member 12, 14 or the vicinity thereof" The reason is that both the grooves 30 and 32 are formed into “V-shaped grooves” by one processing, and the adhesive 36 is attached to both surfaces of the grooves 30 and 32 or one of the surfaces. The adhesive 36 is colored in the same color as or similar to the color of the surfaces of the base materials 13 and 15 (when the surface material 18 is not attached) and the surface color of the surface material 18 (when the surface material 18 is attached). Needless to say, the use of a plurality of types of adhesives 36 is also applicable to the present embodiment.

  Also in this embodiment, as described above, the tapered surface 60 can be formed in advance to make it less susceptible to the influence of foreign matter or the like, and the tape material 28 can be used (further, the first plate material 12). It is also possible to apply the tape material 28 so that the surface of the second plate 14 and the surface of the second plate member 14 have an obtuse angle, and then widen the angle to form the grooves 30 and 32. When the tape material 28 is used, the tape material 28 is attached from a position corresponding to the first groove 30 to a position corresponding to the second groove 32.

(Third embodiment)
A third embodiment will be described with reference to FIG. The first embodiment described above and the third embodiment basically use a third plate member 50 using a wood fiber base material in addition to the first and second plate members 12 and 14. (The third plate member 50 may be the third base member 52 alone, or the surface member 18c may be attached to the surface of the third base member 52 via the adhesive layer 16). , And only the point that the first groove 30 and the second groove 32 are formed at both ends of the third plate member 50, and the common part with the first embodiment in the description of the third embodiment. The description of the first embodiment will be omitted with reference to the description of the first embodiment, and the differences will be mainly described.

  The third base material 52 is formed of a wood fiber base material. As the wood fiber base material, a medium specific gravity fiber board, a high specific gravity fiber board, MDF, etc., in which the wood fiber is solidified with an adhesive and made into a plate shape or a prismatic shape (a product obtained by cutting a plate-like wood fiber base material). It is possible to use a dry-formed wood fiber board such as HDF, or a wet paper-made wood fiber board such as a hard board.

  Further, the surface pattern of the third plate material 50 (if the surface material 18 is not used, the surface pattern of the third base material 52, and if the surface material 18c is used on the surface of the third base material 52, the surface material 18c The surface pattern) is set to be different from the surface patterns of the first plate member 12 and the second plate member 14. For example, by making the surface pattern of each of the plate members 12, 14, and 50 into a plate pattern, a checkered pattern, and a chamfered pattern in order, it is possible to manufacture a checkered material having a real texture.

  Next, using the first plate member 12, the second plate member 14, and the third plate member 50, including the case where the surface material 18 is not used, centering on the “decorative material 10 having the surface material 18” as a finished product. A procedure for manufacturing without using the tape material 28 will be described.

  First, the 1st board | plate material 12, the 2nd board | plate material 14, and the 3rd board | plate material 50 in which the surface material 18 was provided through the adhesive bond layer 16 were prepared (FIG.7 (a)), and each board | plate material 12,14,50 of The third plate member 50 is disposed between the first plate member 12 and the second plate member 14 with the surface being flush, and then the both sides 50a, 50b of the third plate member 50 are placed on the first plate member 12. The side surface 12a and the side surface 14a of the second plate member 14 are abutted and brought into contact with each other (FIG. 7B).

  After the plate members 12, 14, and 50 are brought into contact with each other, the V-shaped rotation (not shown) is applied to the contact surfaces 22 and 23 appearing on the back surfaces of the plate members 12, 14, and 50 while maintaining the contact state. After matching the cutting edge of the saw, it is cut out by a rotary saw to form V-shaped first and second grooves 30 and 32 that match the shape of the rotary saw (FIG. 7C). The V-shaped second groove 32 is formed adjacent to the first groove 30 at the same time as the first groove 30 or before and after the first groove 30. The 3rd board | plate material 50 in which the 1st and 2nd groove | channels 30 and 32 were formed is formed in a front view triangle (this example right-angled isosceles triangle).

  The first and second grooves 30, 32 have groove bottom portions 30 a, 32 a that coincide with the contact surfaces 22, 23, and each base material 13, 15, 15 constituting each plate member 12, 14, 50. 52 (or in this case, the back surface of the surface material 18 is not cut), or the surface of the surface material 18 beyond each base material 13, 15, 52 (that is, each plate material). 12, 14, and 50) or at least near the front side thereof (that is, in this case, at least the butt end portion of the surface material 18 of the third plate 50 is cut and thinned). ing.).

  In the illustrated embodiment, the first and second grooves 30 and 32 are formed by cutting only the third plate member 50 side with the contact surfaces 22 and 23 as a boundary. In the example, the first and second plate members 12 and 14 are formed so as to be symmetrical and adjacent to each other as “a triangle in which the corners on the back surface side become right angles”. Thereby, a wood fiber base material (= 3rd base material 52) is formed in the chamfer 34 of a right triangle shape as mentioned above. Of course, each of the grooves 30 and 32 may be formed as a “V-shaped groove” that is cut not only on the third plate member 50 side but also on the first plate member 12 and the second plate member 14 side. The cut first and second grooves 30 and 32 are cut into a shape that matches the shape of the rotary saw.

  In addition, you may form the 2nd groove | channel 32 in the position away from the 1st groove | channel 30 using the 3rd board | plate material 50 longer in the width direction, and the chamfering length from the corner | angular part 26 to the corner | angular part 27 is sufficient in this case. It will be longer than what is shown. Further, the second groove 32 is formed at a position away from the first groove 30, and the first groove 30 is formed as a “V-shaped groove” in which the second plate 14 side is also cut, and the second groove 32. Are formed as “V-shaped grooves” in the same manner, as shown in FIG. 8, a “U-shaped decorative material 10” can be manufactured. Also in this case, the decorative material 10 in which the surface patterns, materials, and thicknesses of the plate members 12, 14, and 50 are different can be manufactured.

  While the plate members 12, 14, and 50 are kept in contact with each other (at this stage, as shown in the figure, when the surface member 18 is not used, the surface side ends of the plate members 12, 14, and 50, or When the surface material 18 is used, the surface materials 18 are in contact with each other.), A hot melt adhesive, a PUR hot melt adhesive, and an aqueous vinyl urethane adhesive are attached to the surfaces of the grooves 30 and 32. Adhesive 36 such as an adhesive, vinyl acetate adhesive, or urethane adhesive is attached (FIG. 7 (d)), and then both grooves 30, 32 are closed to connect the plate members 12, 14, 50 to each other. By fixing, the decorative material 10 is completed (FIG. 7E).

  Since the 1st thru | or 3rd board | plate materials 12,14,50 are separate members as already stated, the 1st thru | or 3rd board | plate materials 12,14 from which each surface pattern and material (hardness, board thickness, etc.) differ. 50 can be used to manufacture the decorative material 10. For this reason, for example, by making the surface pattern of each of the plate members 12, 14, and 50 into a plate pattern, a checkered pattern, and a chamfered pattern in order, it is possible to manufacture a checkered material having a real texture.

  Further, when the chamfered portion 34 is formed on the wood fiber base material (= the third base material 52), the wood fiber base material is formed so that the fibers are intertwined in a complicated manner and has no directionality (non-directional). Therefore, it is possible to eliminate the possibility that the chamfered portion 34 skips.

  The groove processing method (whether the plate members 12, 14, 50 are moved or the rotary saw is moved), and the position of the groove bottom portions 30a, 32a are defined as "the surface of each plate member 12, 14, 50 or The reason that it is “near the front”, both grooves 30 and 32 are formed into “V-shaped grooves” by one processing, and the adhesive 36 is formed on both surfaces of either of the grooves 30 and 32 or on either surface thereof. The adhesive 36 is the same color as or similar to the color of the surface of each of the base materials 13, 15, 52 (when the surface material 18 is not attached) Needless to say, the present invention can be applied to the present embodiment with respect to coloring in different colors and using a plurality of types of adhesives 36 in combination.

  In addition, as shown in FIG. 10, before the first and second plate members 12 and 14 are brought into contact with the third plate member 50, both side surfaces 50 a and 50 b of the third plate member 50 and the third plate member of the first plate member 12. A tapered surface 60 that forms an acute angle with the surfaces of the plate members 12, 14, 50 having the surface is formed on at least one of the side surface 12a that contacts the plate 50 and the side surface 14a that contacts the third plate member 50 of the second plate member 14. (In FIG. 10, tapered surfaces 60 are formed on both side surfaces 50a and 50b of the third plate member 50). The acute angle formed by the surface of the third plate member 50 and the tapered surface 60 is greater than the angle (acute angle) formed by the surface of the third plate member 50 and the surface formed by the V-shaped groove 30 or 32 formed later. large.

  As a result, even if foreign matter or the like exists between the side surface 50a of the third plate member 50, the side surface 12a of the first plate member 12, and the side surface 14a of the second plate member 14, the plate members 12, 14, 50 are brought into contact with each other. By letting out the foreign matters when contacting, the surfaces of the plate members 12, 14, 50 can be brought into contact with each other accurately, and the production yield can be dramatically improved by suppressing the occurrence of defects.

  Similarly, as shown in FIG. 10, a side surface 12 b opposite to the side surface 12 a in contact with the third plate material 50 in the first plate material 12 is formed on the ruler surface 62, and the first plate material 12. When the third plate member 50 and the second plate member 14 are brought into contact with each other, the side surface 50a of the third plate member 50 in which the tapered surface 60 is formed on the side surface 12a of the first plate member 12 positioned with reference to the ruler surface 62. May be pressed.

  Thereby, since the 3rd board | plate material 50 and the 2nd board | plate material 14 can be correctly contact | abutted with respect to the 1st board | plate material 12 correctly positioned on the basis of the ruler surface 62, generation | occurrence | production of a defect can be suppressed and a production yield can be suppressed. Further improvement can be achieved.

  Next, the case where it manufactures using the tape material 28 is demonstrated. As shown in FIG. 9, the surfaces of the plate members 12, 14, 50 around the third plate member 50 in a state where the side surfaces 12 a, 14 a, 50 a of the plate members 12, 14, 50 are in contact with each other and are flush with each other. A flexible tape material 28 is affixed to the groove 30 (FIG. 9B), grooves are processed in the same manner as described above (FIG. 9C), and the adhesive 36 is attached to both grooves 30, 32 (FIG. 9). 9 (d)), the plate members 12, 14, 50 are fixed to each other by being bent with the tape member 28 as a guide, and finally the tape member 28 is peeled off (FIG. 9 (e)).

  The timing of attaching the tape material 28 is at any stage from when the plate members 12, 14, 50 are brought into contact with each other until the grooves 30, 32 formed on the contact surfaces 22, 23 are closed. Anytime if you want. Further, as shown in the figure, the tape material 28 may be pasted from the first plate material 12 to the second plate material 14 beyond the third plate material 50, or between the first plate material 12 and the third plate material 50, and the second plate material 50. The two plate members 14 and the third plate member 50 may be attached separately. As described above, the same applies when the second groove 32 is formed at a position away from the first groove 30.

  The side surfaces of the first and second plate members 12 and 14 are thus bent by bending the flexible tape member 28 attached to the surface of the second plate member 14 with the first plate member 12 and the third plate member 50 interposed therebetween. The tips of 12a and 14a and the thin tip of the third plate member 50 can be adhered and fixed while maintaining a state where they are in contact with each other. At this time, as already described, accurate tip contact is performed by the pressing force generated at the portion of the tape material 28 that is bent at the bent portion. In particular, it is more effective when the V-shaped grooves 30, 32 reach the surface and the tips of the plate members 12, 14, 50 are thinned. The tape material 28 also has a role of preventing the adhesive 36 attached to both grooves 30 and 32 from protruding to the surface. Thus, by using the tape material 28, it is possible to manufacture the cosmetic material 10 having a good appearance in which the tip portions of the plate materials 12, 14, and 50 are accurately matched.

  As shown in FIG. 10, the surface of the first plate 12 and the surface of the third plate 50 that are in contact with each other means an obtuse angle (an angle greater than 90 degrees and less than 180 degrees. The tape material 28 described above is applied in a state where the tape material 28 is formed (FIG. 10 (b)). After affixing the material 28, the grooves 30 and 32 may be formed after spreading so that the contact angle between the two plate materials 12 and 50 becomes larger (FIG. 10C). In the present embodiment, the first plate member 12 and the third plate member 50 are in contact with each other at an obtuse angle, but of course, the second plate member 14 and the third plate member 50 may be in contact with each other at an obtuse angle. Both the plate member 12 and the second plate member 14 may be brought into contact with the third plate member 50 at an obtuse angle.

  As a result, the two plate members 12, 50 are brought into contact with the tape member 28 attached to the surfaces of the two plate members 12, 50 in a state where the surface of the first plate member 12 and the surface of the third plate member 50 form an obtuse angle. When both plate members 12, 50 are expanded so that the angle becomes larger (preferably, the angle between the surface of the first plate member 12 and the surface of the third plate member 50 is 180 degrees). The force to try to shrink arises. Since both the board | plate materials 12 and 50 are pressed more strongly by this contraction force, the front-end | tip parts of both the board | plate materials 12 and 50 match more accurately, and the cosmetic material 10 with a more attractive appearance can be manufactured.

  In addition, as can be said for all of the first to third embodiments, a general printing sheet requires a printing lot printed on a rotary press in units of thousands to tens of thousands of meters. If it is used for products with large areas such as wall materials and flooring, there is no problem even if the printing lot is large in this way, but cosmetics with a small construction area such as fences, treads, baseboards, etc. In the case of using a printing sheet for a large number of printing lots, it was not possible to prepare many kinds of surface patterns and there was no freedom of selection. In particular, since the pattern used for the chamfered portion 34 has a small amount of use, the above-mentioned problem of the printing lot is remarkable.

  Therefore, a paper having an ink receiving layer is attached in advance as the surface material 18a, 18b, 18c to the surface of each base material 13, 15, 52, and a desired surface pattern is formed on the surface of the paper by ink jet printing. It is preferable to keep. By using inkjet printing, the decorative pattern of the surface material 18a, 18b, 18c can be printed in a smaller area (for example, 3 × 6 plate unit), and even if a variety of surface patterns are prepared, inventory risk is low and free This is because a large degree of product design becomes possible.

  In addition, when the surface materials 18a, 18b, and 18c on which the decorative pattern has been formed are pasted on the base materials 13, 15, and 52, until the adhesive that pastes the surface materials 18a, 18b, and 18c is solidified. However, as described above, the paper having the ink receiving layer is stuck and integrated on the surfaces of the base materials 13, 15, and 52 in advance. In addition, by performing printing as necessary, the curing period as described above becomes unnecessary, and it becomes possible to produce a cosmetic material with a short delivery time.

  Ink jet printing may be performed using a facility capable of printing on a general thick plate, and it is preferable to use UV colored ink having excellent water resistance.

  In addition, by applying a transparent paint to the surface of ink jet printing immediately after ink jet printing (undercoating), it is possible to prevent damage due to transport or the like when a tape is applied or grooves are processed in a subsequent process.

  As such a transparent paint, a general paint for acrylic, urethane or the like is used, but an undercoat containing a so-called antifriction agent such as white alumina or green carbon is preferably used. Needless to say, the surface of the undercoated transparent coating may be further coated with a transparent coating (overcoating) so as to erase the scratches generated during transportation.
