However, in the technique of Patent Document 1, certain color pattern information is set in the construction pattern information. For this reason, regardless of the base surface on which the board material is laid, the entire laid board material looks like a constant pattern (same pattern), so that, for example, even in different rooms, the image of the same room is given.

Further, in the technique of Patent Document 1, since the pattern is printed on the surface of the plate material while associating the information of the laying position of the plate material to be laid with each plate material, it is possible to stock the plate material on which the pattern is printed in advance. Can not. Therefore, it may take a long time from printing the surface of the plate material to laying the plate material.

The present invention has been made in view of these points, and an object of the present invention is to select a pattern of the entire laid plate material according to a preference so that the selected pattern can be obtained in a shorter period of time. It is an object of the present invention to provide a method of constructing a plate material capable of laying the plate material on the base surface.

In view of these issues, the inventor has made extensive studies, and as a result, the image when looking at the pattern of the entire laid board is the ratio (ratio) of the board on which different types of wood grain patterns are printed. By making a decision, we gained new knowledge that it will change significantly.

The present invention is based on a new finding by the inventor, and the method of constructing a plate material according to the present invention is to lay a plurality of plate materials on which a wood grain pattern is printed on a base surface so that the plate materials are adjacent to each other. A step of determining the ratio of each type of board to be laid on the base surface with respect to a plurality of types of boards on which different types of wood grain patterns are printed, and the determined ratio. Based on the above, a step of calculating the number of the plate materials of each type to be laid on the base surface, a step of determining the laying position where the plate materials of each type are laid on the base surface, and the determined laying position. It is characterized by including a step of laying each kind of plate material.

According to the present invention, the pattern of the entire board material after laying is determined by determining the ratio of each type of board material laid on the base surface to a plurality of types of board materials printed with different types of wood grain patterns. You can set it to your liking. Then, the number of boards of each type may be calculated based on the determined ratio, and the boards corresponding to the number of boards may be prepared. Therefore, it is also possible to print a wood grain pattern on the surface of the boards in advance and stock them. it can.

As a result, the pattern of the entire laid plate material can be easily selected according to the preference, and the plate material can be laid on the base surface so that the entire plate material has the selected pattern in a shorter period of time. ..

In a more preferred embodiment, in the step of determining the ratio of the plate materials, one ratio is selected from a plurality of different ratios preset for the plurality of types of plate materials, whereby the plate materials of each type are selected. Determine the percentage.

According to this aspect, the ratio of each type of plate material is determined by selecting one ratio from a plurality of different ratios set in advance, so that the image of the pattern of the entire plate material can be easily adjusted to the preference. Can be selected for.

In a more preferable embodiment, in the step of determining the laying position, among the above-mentioned types of plate materials, a plate material laid at a laying position other than the laying position at the corner of the base surface, and at least one adjacent to the plate material. The laying position of each board is determined so that the board has a different grain pattern. According to this aspect, it is possible to prevent the adjacent plate materials from being all the same type of plate material, and to prevent the same type of plate material from being laid unevenly on the base surface.

As yet another preferred embodiment, in the step of determining the laying position, the step of assigning a number based on a random number to each of the plate materials and the step of laying the plate material at the laying position where each plate material of the base surface is laid are described. The process of assigning different numbers according to the number of plate materials, the numbers assigned to the plate materials, and the numbers assigned to the laying positions correspond to each other in numerical order, and the respective types of plate materials are applied to the base surface. Determine the laying position to be laid.

According to this aspect, the plate materials assigned numbers based on random numbers can be arranged in numerical order according to the construction positions assigned different numbers, so that the same type of plate materials are randomly scattered. It can be placed in a random number.

Further, in a preferred embodiment, the plurality of types of board materials on which different types of wood grain patterns are printed include the main board material on which only the wood grain pattern is printed, and knots, cracks, slightly, heather, bark, metal bars, and sugar. At least one type of wood grain-only pattern with a pattern selected from a group of patterns according to streaks, false cores, ate, uneven color, ridge patterns, nail hole marks, and sawtooth scars. In the step of determining the ratio of the plate material including the above sub-plate material, the ratio of the main plate material is determined to be larger than the ratio of the sub-plate material.

According to this aspect, the board material on which the pattern of only wood grain is printed occupies the main part of the whole board material laid, and the sub board material on which the pattern such as other knots is printed occupies the whole board material laid. Are distributed and arranged. As a result, the board material can be laid so that the laid board material has a natural pattern that does not give a sense of discomfort.

As a particularly preferable embodiment, in the step of determining the laying position, the determined laying position of the sub-plate material is changed so that the sub-plate materials of the same type are not arranged at the adjacent laying positions.

According to this aspect, since the sub-plate materials of the same type are not laid at adjacent laying positions but are laid at distant positions, the pattern of the sub-plate materials is not locally concentrated on the entire laid plate materials. , The wood grain pattern of the secondary board can be made inconspicuous.

According to the present invention, the pattern of the entire laid plate material can be easily selected according to the preference, and the plate material can be laid on the base surface so as to have the selected pattern in a shorter period of time.

It is a schematic plan view. It is a schematic conceptual diagram of the construction system which concerns on this embodiment.

Hereinafter, a method of constructing a plate material according to an embodiment of the present invention will be described with reference to FIGS. 1 to 8.
In the method of constructing the plate material according to the present embodiment, a plurality of plate materials printed with a wood grain pattern are laid on the base surface so that the plate materials are adjacent to each other. Specifically, in the present embodiment, a series of steps shown in FIG. 1 to be described later is performed. The base surface on which the board material is laid is, for example, the floor, wall, cupboard, etc. of a room, entrance, kitchen, etc., and if a plurality of board materials can be laid, the base surface is particularly suitable. It is not limited. First, the plate material laid on the base surface will be described.

1. 1. Board material The board material laid on the lower ground is a board material with a wood grain pattern printed on the surface of the base material. Specifically, the base material on which the wood grain pattern is printed is not particularly limited as long as the wood grain pattern can be printed on the surface thereof, and the materials thereof include, for example, plywood and particle board ( PB), wood fiberboard (MDF, insulation board, hardboard, etc.), oriented strand board (OSB), LVL, or laminated wood. In addition to this, a composite type base material in which a resin and wood are mixed may be used, and a polyvinyl chloride resin, a polyurethane resin, or a polyolefin resin (polyethylene, polypropylene, polyethylene vinyl acetate, or polyvinyl alcohol) may be used. Etc.) may be a resin base material. In the present embodiment, as a preferred embodiment, a veneer derived from natural wood such as a veneer or a sawn board is attached to the surface of the printed side of these base materials.

Materials for veneer include, for example, beach, oak, maple, zelkova, walnut, cinnamon, oak, ash, kiri, hinoki, sugi, mahogany, teak, rosewood, tochi, black oyster, ash, elm, hippopotamus, rosewood, etc. Alternatively, ebony and the like can be mentioned. In the case of veneer, the thickness is preferably in the range of 0.1 to 1.0 mm, and in the case of veneer, the thickness is preferably in the range of 1 mm to 3 mm. The base material on which the wood grain pattern is printed may be a solid wood composed of only such a veneer.

Here, the surface of the veneer is made of natural wood, and a natural wood grain pattern is formed. Therefore, it is preferable to print a wood grain pattern different from the natural wood grain pattern on the surface of the base material by, for example, inkjet printing so as to leave the uneven shape of the surface (woody surface) of these natural woods. As a result, it is possible to obtain a highly designed plate material in which the uneven shape of natural wood is formed and the desired wood grain pattern is formed by the adhesion of ink particles.

In the present embodiment, the wood grain pattern formed (printed) by the ink (particles) is different from the surface of the single plate, and the surface of one plate material is photographed as an image, and the pattern corresponding to the photographed image ( The surface pattern of wood) can be obtained by printing with an inkjet printer.

In the present embodiment, the ink for inkjet printing is composed of, for example, four colors of yellow, magenta, cyan, and black, and these inks are used to form an ink layer on the surface of a single plate to form a wood grain pattern. Print. Here, the ink used for inkjet printing may be any of water-based ink, oil-based ink, and ultraviolet curable ink. If an ultraviolet curable ink is used as the printing ink, the printed ink is hardly impregnated in the veneer, and a clear surface pattern can be obtained.

More specifically, in the present embodiment, unlike the conventional technique, an ultraviolet curable ink having a fine particle size is sprayed on the surface of a veneer (base material). Specifically, the ink droplets 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 are separated and adhered to each other, and the surface is exposed from the ink particles between the ink particles. Then, the printed surface is irradiated with ultraviolet rays to cure the ink particles.

Here, the "plurality of board materials on which different types of wood grain patterns are printed" in the present embodiment are the main board material on which only the wood grain pattern is printed, and knots, cracks, shavings, 杢, and bark. A pattern selected from a group of patterns according to gold streaks, sugar streaks, false cores, ate, uneven color, ridge patterns, nail hole marks, and sawtooth scars is further added to the wood grain only pattern. It consists of at least multiple types of sub-plate materials.

More specifically, in the present embodiment, as shown in FIG. 2 to be described later, the plurality of types of sub-plate materials have a pattern of knots, cracks, shavings, heather, bark, or metal streaks having only wood grain. Further, it is composed of 5 types (B type to F type) of sub-plate materials provided. In addition, the main plate material corresponds to the type A plate material in FIG.

In addition, the "pattern of only wood grain" is a pattern consisting of only wood grain such as grain or plank. Therefore, the main plate material is a wood grain pattern without a pattern such as knots given to the sub plate material, and is a wood grain pattern of a plate material which is usually considered to be good. Further, the wood grain pattern of the board material for each type may be a wood grain pattern of the same shape and color, but the type of the wood grain pattern can be specified and can be classified into each type of board material. For example, these wood grain patterns do not have to have the same shape and color.

In the present embodiment, a plurality of types of board materials printed with different types of wood grain patterns may be pre-printed and stocked. For example, by the step of laying the board materials in step S4 of FIG. 1 shown below. It just needs to be prepared.

2. About the construction method of the plate material The construction method of the plate material according to this embodiment will be described below.
2-1. Step of determining the ratio of each type of plate material First, in the present embodiment, as shown in step S1 of FIG. 1, the ratio of each type of plate material is determined. Specifically, the ratio of each type of plate material laid on the base surface is determined with respect to a plurality of types of plate materials printed with different types (types A to F shown in FIG. 2) of wood grain patterns.

More specifically, in the present embodiment, a main plate material of type A in which a pattern of only wood grain such as grain or grain is printed on the plate material, and knots, cracks, shavings, heather, bark, or gold. The ratio of each type of plate material to the five types (types B to F) of sub-plate materials in which the streak pattern is further added to the pattern of only wood grain is determined.

In the present embodiment, the above-mentioned five types of sub-plate materials are used as the sub-plate materials for determining the ratio. Alternatively, a further type of auxiliary plate material such as a pattern corresponding to the scar of the saw may be used, or a plurality of types of plate materials combining these patterns may be used.

Further, among the A to E type plate materials (main plate material and sub plate material), the wood grain pattern of each plate material printed on a pair of plate materials of the same type may be a line-symmetrical wood grain pattern. As a result, of the pair of board materials, the wood grain pattern of one board material and the wood grain pattern of the other board material become a line-symmetrical wood grain pattern. It looks as if the planks were cut out of a single piece of wood. In this case, a pair of plate members may be laid adjacent to each other, whereby such an effect can be further expected.

Further, the ratio of the A type main plate material and the five types of B type to F type sub plate materials may be set each time according to the construction of the plate material, but in the present embodiment, FIG. 2 shows. As shown, the ratio of each type of plate material is determined by selecting one ratio from a plurality of different preset ratios with respect to the five types of plate materials of types A to F.

For example, in pattern I, A type is 60%, B type to E type is 10%, and F type is 0%, and in pattern II, A type is 40%, B type to E type is 15%, and F type is 0%. The ratio of each type of plate material is set so that the image of the pattern on the surface of the entire plate material (plate structure) when the plate material is laid is different. Therefore, the ratio of each type of plate material is determined by selecting one ratio (pattern) from a plurality of different ratios (patterns) set in advance, so that the image of the pattern of the entire plate material can be easily adjusted to the preference. You can choose.

In Patterns I to III, the ratio of the main plate material of type A is set to be larger than the ratio of the sub plate material of type B to F. As a result, the main plate material of type A on which the pattern of only wood grain is printed occupies the main part of the entire laid plate material, and the sub plates of type B to F on which patterns such as other knots are printed. It can be distributed and arranged over the entire laid plate material. As a result, each plate material can be laid so that the entire laid plate material (plate structure) has a natural pattern that does not give a sense of discomfort in terms of design.

As in pattern IV, the ratio of the main plate material of type A is set to 0% among the plate materials to be laid, and the ratio is determined only by the other sub-plate materials of types C to E without including the main plate material. Also, as in pattern V, the plate materials of types A to E may be determined in the same ratio.

2-2. Step of calculating the number of plates of each type Next, the process proceeds to step S2 of FIG. 1, and the number of plates of each type to be laid on the base surface is calculated based on the determined ratio. Here, in the present embodiment, as an example thereof, a method of calculating the number of plate materials of each type when the pattern I shown in FIG. 2 is selected will be described below.

In the present embodiment, 72 plate materials are laid on the base surface divided into 18 rows × 4 columns (see, for example, FIG. 5). Here, when pattern I is selected as the ratio of the plate material, it is 60% for type A, 10% for types B to E, and 0% for type F. First, the number of laid sheets is multiplied by the ratio of each type of plate material.

Specifically, the main plate material of type A is 72 sheets x 60%, which is 43.2 sheets, and the sub-plate material of types B to E is 72 sheets x 10%, which is 7.2 sheets. The value of the number of sheets calculated here is not an integer. Therefore, in the present embodiment, the value of the first decimal place of the calculated number of sheets of types B to E is rounded down so that the total number of sheets of each plate material becomes the number of laid sheets (72 sheets). Increase (adjust) the value of the number of main plates of.

As a result, the number of type B to type E plate materials is 7, and the number of type A plate materials is 44. In the present embodiment, the type A main plate material is a plate material on which a pattern of only wood grain is printed. Therefore, even if the number of type A main plate materials increases, the pattern of the entire laid plate material may feel uncomfortable. Absent.

2-3. Step of determining the laying position Next, the process proceeds to step S3 of FIG. 1, and the laying position where each type of plate material is laid on the base surface is determined. First, a number based on a random number is assigned to each of the A to E plate materials. Specifically, as shown in FIG. 4, 44 main plate materials of type A and 7 sub-plate materials of types B to E are arranged in the order of numbers 1 to 72, and these are arranged using a random number table or the like. Numbers based on random numbers are assigned to the A to E types of board materials.

When using a random number table, for example, the rows and columns of the random number table are determined based on the date and time when this step is performed, and the random numbers arranged after that from the numerical values of the random number table corresponding to the determined rows and columns. Are read out in order. For example, in the present embodiment, the numerical value of the allocation start read from the rows and columns determined by the random number table is "70", and the numerical values of the random number table are read out in order from there (specifically, the numerical values 69 and 25). , 11,76, ...), Assign numbers based on random numbers to each plate material of type A to type E.

Next, different numbers are assigned to the laying positions on the base surface where a total of 72 plate materials of types A to E are laid, depending on the number of plate materials to be laid. Specifically, as shown in FIG. 5, serial numbers from 1 to 72 are assigned as allocation numbers in order from the upper left to the laying positions where each plate material on the base surface is laid.

Next, the random number assigned to the plate material and the allocation number assigned to the laying position are associated with each other in numerical order to determine the laying position where each type of plate material is laid on the base surface. Specifically, the random numbers assigned to each of the A to E plate materials shown in FIG. 4 are rearranged in ascending order as shown in FIG.

In the present embodiment, the random numbers are "0", "2", "3", "4" ... in ascending order, and the plate materials to which the random numbers are assigned are "A type", "A type", "A type". "A type", "C type", and so on, and the random numbers are rearranged in this order according to the type of plate material.

Next, the random number assigned to the rearranged board material is associated with the allocation number (serial number) of the laying position in ascending order. As a result, as shown in FIG. 7A, the laying position to be laid on the floor base surface of each of the 72 plate materials of the A to E types is determined. In this way, each type of plate material can be randomly arranged based on a random number.

Here, as shown in FIG. 7A, (1) type B sub-plate material of allocation numbers "15" and "16", (2) type D sub-plate material of allocation numbers "26" and "45", ( 3) Type D sub-plate material with allocation numbers "30" and "47", (4) Type C sub-plate material with allocation numbers "43" and "61", (5) Type E sub-plate material with allocation numbers "63" and "64" The sub-plate materials are arranged adjacent to each other.

Therefore, in the present embodiment, the determined laying position of the sub-plate material is changed so that the sub-plate materials of the same type are not arranged at the adjacent laying positions. Specifically, as shown in FIG. 7B, (1) the sub-plate material of type B having the allocation number "15" and the main plate material of type A having the allocation number "10" are replaced. Similarly, (2) the D-type sub-plate material with the allocation number "45" and the C-type main plate material with the allocation number "68" are replaced, and (3) the D-type sub-plate material with the allocation number "47" are replaced. Replace with the A type main plate material with the allocation number "17". Further, (4) the C type sub-plate material of the allocation number "61" and the B type sub-plate material of the allocation number "37" are replaced, and (5) the D type sub-plate material of the allocation number "63" and the allocation. Replace with the A type sub-plate material of number "9".

In this way, the sub-plate materials of the same type are not arranged at adjacent laying positions but are laid at distant positions, so that the pattern of the sub-plate materials is not locally concentrated on the entire laid plate material. The wood grain pattern of the secondary board can be made inconspicuous.

In the present embodiment, as described above, the laying position of each type of plate material is determined using the random number table. However, for example, among the types A to E, the plate materials are laid at the laying positions other than the laying positions (“1”, “18”, “55”, “72” in FIG. 5) at the corners of the base surface. The laying position of each plate material may be determined so that the plate material to be formed and at least one plate material adjacent thereto have different grain patterns. As a result, it is possible to prevent the adjacent plate materials from being all the same type of plate material, and to prevent the same type of plate material from being laid unevenly.

2-4. Step of laying the plate material Next, the process proceeds to step S4 of FIG. 1, and each type of plate material is laid at the determined laying position. Specifically, 72 types of A to E plate materials are laid at the changed laying position shown in FIG. 7 (b). As a result, it is possible to obtain a plate structure in which the sub-plate materials of the same type are not arranged at adjacent laying positions and are laid at distant positions.

In this way, in the present embodiment, the ratio of each type of board to be laid on the base surface is determined with respect to the plurality of types of board on which different types (A to E) of wood grain patterns are printed. Therefore, the pattern of the entire plate material after laying can be selected according to the preference.

In addition, since the number of boards of each type may be calculated based on the determined ratio and the boards corresponding to the number of boards may be prepared, it is also possible to print a wood grain pattern on the surface of the boards in advance and stock them. it can.

Further, in the present embodiment, since the plate material in which the wood grain pattern is printed on the surface of the base material is manufactured by inkjet printing, it is possible to produce a wide variety of small lots, and it is possible to produce a wide variety of wood grain patterns. Therefore, the surface of the entire plate material (plate structure) can be applied on demand to a pattern that suits the taste.

Here, the steps S1 to S3 described above may be performed using the construction system 1 shown in FIG. The construction system 1 includes an input device 11, an arithmetic unit 12 such as a CPU, a storage device 13 such as a RAM, and a display device 14.

In the present embodiment, the input device 11 determines the type of plate material shown in step S1, the ratio of each type of plate material, the number of plate materials (rows and columns) laid on the base surface shown in steps S2 and S3, and the like. It is connected to the arithmetic unit 12 so that the input information can be input to the arithmetic unit 12.

The arithmetic unit 12 calculates the number of each type of plate material shown in step S2 based on the input information from the input device 11, and determines the laying position of each plate material shown in step S3. Here, the storage device 13 has a pattern corresponding to the ratio of each type of plate material shown in step S1 (see FIG. 2), a random number table shown in step S3, and a wood grain pattern printed on each type of plate material. Information such as images is stored. In this way, the arithmetic unit 12 calculates the number of plates of each type by reading the information from the storage device 13 based on the input information from the input device 11, and performs the above-mentioned series of operations. The laying position of each plate material is determined by calculation.

The display device 14 displays a pattern (see FIG. 2) corresponding to the ratio of each type of plate material output from the storage device 13 via the arithmetic unit 12, and the arithmetic unit is based on the input information from the input device 11. The state in which each type of plate material is laid at the laying position determined in 12 (see FIGS. 7A and 7B) is displayed.

According to this construction system 1, a state in which the arithmetic unit 12 determines the laying position of each type of plate material based on the information input from the input device 11, and each plate material is laid at the laying position determined by the arithmetic unit 12. Can be displayed on the display device 14.

This makes it possible to check the pattern of the entire plate material (plate structure) laid in advance before constructing the plate material, and further, until the entire plate material (plate structure) has the desired pattern, each type. It is possible to change the ratio of the plate material and confirm this.

Although the embodiments of the present invention have been described in detail above, the present invention is not limited to the above-described embodiments, and various designs are designed without departing from the spirit of the present invention described in the claims. You can make changes.

In the present embodiment, the plate material to be constructed is a rectangular plate material, but for example, a gantry type plate material may be used, as long as the plate materials can be laid on the base surface so as to be adjacent to each other. The shape is not particularly limited.
