Description

  The present invention relates to a plate material construction method suitable for laying 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.

  Conventionally, in order to improve the design of a plate material, a plate material in which a pattern is printed on the surface of the plate material by ink jet printing or the like and the pattern is formed with ink may be used. When laying a plurality of such plate materials on the base surface so that the plate materials are adjacent to each other (adjacent), prepare the necessary number of different types of plate materials having different types of patterns on the base surface. These plate materials are laid on the ground surface. Here, if a plurality of plate materials with the same type of pattern formed are repeatedly and continuously laid, the entire laid plate material has a sense of incongruity, so the plate materials with the same type of pattern formed are dispersed. It is preferable that it is laid.

  In view of such points, for example, in the techniques according to Patent Documents 1 and 2, construction pattern information partitioned into a predetermined shape by a plurality of plate materials is prepared, and the shape and size of the base surface are included in the construction pattern information. Information is plotted, color pattern information, laying position information, and the like for each plate material are determined, and a surface design is printed and marked on each plate material based on the information. Thereafter, a plurality of printed and marked plate materials are laid at predetermined laying positions.

  According to this aspect, before laying a plurality of types of plate materials on which different types of patterns are formed, the color pattern information and the laying position information of each plate material are determined and printed. Can be prevented from being laid.

  However, in the technique of Patent Document 1, certain color pattern information is set in the construction pattern information. For this reason, since the whole laid board | plate material looks like a fixed pattern (same pattern) irrespective of the base surface which lays a board | plate material, even if it is a different room, the image like the same room will be given.

  Furthermore, in the technique of Patent Document 1, since the pattern is printed on the surface of the plate material while associating the information on the laying position of the laid plate material with each plate material, it is not possible to stock the plate material on which the pattern is printed in advance. Can not. For this reason, 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 the above points, and the object of the present invention is to select the pattern of the entire laid board material according to preference, so that the selected pattern can be obtained in a shorter period of time. Another object of the present invention is to provide a method for constructing a plate material that can be laid on a base surface.

  In view of such problems, the inventor has intensively studied, and as a result, the image when looking at the pattern of the entire laid board material is the ratio (ratio) of the board material printed with different types of wood grain patterns. By making a decision, I gained new knowledge that it would change significantly.

  The present invention is based on the new knowledge by the inventor, and the plate material construction method according to the present invention lays a plurality of plate materials on which a wood grain pattern is printed so that the plate materials are adjacent to each other. A method for constructing a plate material, a step of determining a ratio of each type of plate material laid on the base surface, with respect to a plurality of types of plate materials printed with different types of wood grain patterns, and the determined ratio Based on the above, the step of calculating the number of each type of plate material laid on the base surface, the step of determining the laying position where each type of plate material is laid on the base surface, and the determined laying position And a step of laying each type of plate material.

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

  As a result, it is possible to easily select the pattern of the entire laid board material according to preference, and to lay the board material on the ground surface so that the entire board material becomes the selected pattern in a shorter period of time. .

  As a more preferable aspect, in the step of determining the ratio of the plate materials, by selecting one ratio from a plurality of different preset ratios with respect to the plurality of types of plate materials, Determine the percentage.

  According to this aspect, by selecting one ratio from a plurality of different ratios set in advance, the ratio of each type of plate material is determined. Can be selected.

  As a more preferable aspect, in the step of determining the laying position, among the various types of plate materials, a plate material laid at a laying position excluding a laying position at a corner of the base surface, and at least one adjacent thereto The laying position of each plate material is determined so that the plate material has a different wood grain pattern. According to this aspect, it is possible to avoid that the adjacent plate materials are all the same type of plate material, and to prevent the same type of plate material from being laid on the base surface.

  As another preferred aspect, in the step of determining the laying position, the step of allocating a number based on a random number to each plate member, and the laying position where each plate member of the base surface is laid The step of assigning different numbers according to the number of plate members, the numbers assigned to the plate members, and the numbers assigned to the laying positions are made to correspond in order of numbers, and each type of plate member is placed on the base surface. Determine the laying position to be laid.

  According to this aspect, it is possible to arrange plate materials assigned numbers based on random numbers, corresponding to the construction positions assigned different numbers in the order of numbers, and therefore randomly distribute the same type of plate materials. Can be placed.

  Furthermore, as a preferred embodiment, the plurality of types of plate materials on which different types of wood grain patterns are printed are the main plate material on which only the wood grain pattern is printed, and the knots, cracks, heels, wrinkles, perforations, metal bars, sugar A pattern selected from a group of patterns according to streaks, false cores, verticals, uneven color, burrs, patterns of nail holes, and saw marks, and at least one kind further added to the pattern of wood grain only In the step of determining the ratio of the 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 only the pattern of wood grain is printed occupies the main part of the entire laid board material, and the sub board material on which the pattern of other nodes is printed is applied to the entire laid board material. Distributed. Thereby, a board | plate material can be laid so that it may become a natural pattern without a sense of incongruity as the whole laid board | plate material.

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

  According to this aspect, the same type of sub-plate materials are not laid at adjacent laying positions, but are laid at separate positions, so that the pattern of the sub-plate materials does not concentrate locally on the entire laid plate material. The sub-plate material can be made inconspicuous.

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

It is a typical top view. It is a typical conceptual diagram of the construction system concerning this embodiment.

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

1. About the plate material The plate material laid on the lower ground is a plate material in which a wood grain pattern is 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. Examples of the material include plywood and particle board ( PB), wood fiberboard (MDF, insulation board, hardboard, etc.), oriented strand board (OSB), LVL, or laminated wood. In addition, a composite base material in which a resin and wood are mixed may be used. A polyvinyl chloride resin, a polyurethane resin, or a polyolefin resin (polyethylene, polypropylene, polyethylene vinyl acetate, or polyvinyl alcohol). Etc.) may be a resin base material. In this embodiment, as a preferable aspect, a veneer derived from natural wood such as a veneer or a ground plate is attached to the surface of the substrate on which the substrate is printed.

  As the material of the veneer, for example, beach, oak, maple, zelkova, walnut, china, oak, yachidamo, kiri, hinoki, cedar, mahogany, teak, rosewood, tochi, blackwood, shioji, elm, hippopotamus, rosewood, Or octane can be mentioned. In the case of a projecting plate, the thickness is preferably in the range of 0.1 to 1.0 mm, and in the case of a ground plate, 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 material composed only of such a single plate.

  Here, the surface of the veneer is made of natural wood and has a natural wood grain pattern. For this reason, it is preferable to print a grain pattern different from the natural grain pattern on the surface of the substrate by, for example, ink jet printing so as to leave the uneven shape of the surface of the natural wood (woody surface). Thereby, the uneven | corrugated shape of natural wood is formed, and the plate material with high designability in which the favorite grain pattern was formed by adhesion of an ink particle can be obtained.

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

  In this 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 a wood grain pattern by forming an ink layer on the surface of a single plate. 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 into the single plate, and a clear surface pattern can be obtained.

  More specifically, in the present embodiment, unlike the conventional technique, ultraviolet curable ink having a fine particle diameter is sprayed on the surface of a single plate (base material). Specifically, the ink droplet is preferably in the range of 1 to 20 pl, more preferably in the range of 3 to 14 pl. In this way, uncured ink particles adhere to each other and the surface is exposed from the ink particles between the ink particles. Thereafter, the ink particles are cured by irradiating the printing surface with ultraviolet rays.

  Here, the `` plural types of plate materials on which different types of wood grain patterns are printed '' as used in the present embodiment refers to the main plate material on which only the wood grain patterns are printed, and knots, cracks, and so on. A pattern selected from a group of patterns according to gold bars, sugar bars, false cores, attes, uneven color, patterns of burrs, traces of nail holes and scars of saws is added to the pattern of wood only It consists of at least a plurality of 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 knots, cracks, folds, perforations, or metal bars in a pattern with only wood grain. Furthermore, it consists of the provided 5 types (B type-F type) sub-plate materials. The main plate material corresponds to a type A plate material in FIG.

  Note that the “pattern with only wood grain” is a pattern made only of wood grain, such as a grid or a plank. Accordingly, the main plate material is a wood grain pattern without a pattern such as a knot imparted to the sub plate material, and is a wood grain pattern which is normally considered good. Further, the wood grain pattern of each type of plate material may be the same shape and color wood grain pattern, 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 this embodiment, a plurality of types of plate materials on which different types of wood grain patterns are printed may be pre-printed and stocked. For example, by the step of laying the plate material in step S4 of FIG. It only has to be prepared.

2. About the construction method of a board | plate material Below, the construction method of the board | plate material which concerns on this embodiment is demonstrated.
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 on which different types (A type to F type shown in FIG. 2) are printed.

  More specifically, in the present embodiment, the main plate material which is a type A on which a pattern of only a grain of wood or a grain is printed on the plate material, and a knot, a crack, a wrinkle, a crust, or a gold The ratio of each type of plate material to the five types (B type to F type) sub-plate materials in which the streak pattern is further added to the pattern having only the grain is determined.

  In the present embodiment, the above-described five types of sub-plate materials were used as the sub-plate materials for determining the ratio. For example, sugar stripes, false cores, ate, color unevenness, patterns of edges, patterns of traces of nail holes, Alternatively, a further type of sub-plate material such as a pattern corresponding to a saw scar may be used, or a plurality of types of plate materials combining these patterns may be used.

  Furthermore, among the A-type 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, among the pair of plate members, the grain pattern of one plate member and the grain pattern of the other plate member become a line-symmetrical grain pattern. Therefore, when these pair of plate members are laid on the ground surface, It looks as if the board was cut from one piece of wood. In this case, a pair of plate members may be laid adjacent to each other, and this effect can be further expected.

  Moreover, although 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, in the present embodiment, FIG. As shown, the ratio of each type of plate material is determined by selecting one rate from a plurality of different preset rates for the five types of plate materials A to F.

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

  In the patterns I to III, the ratio of the A type main plate material is set to be larger than the ratio of the B type to F type sub plate material. Thereby, the A type main board material on which only the pattern of the grain is printed occupies the main part of the entire laid board material, and the B type to F type sub board on which other patterns such as nodes are printed, It can disperse | distribute and arrange | position with respect to the whole board | substrate laid. Thereby, each board | plate material can be laid so that it may become a natural pattern which does not feel discomfort in design as the whole board | plate material laid (plate structure).

  As in Pattern IV, among the plates to be laid, the ratio of the main plate material of type A is set to 0%, the main plate material is not included, and the ratio is determined only by the other C-type to E-type sub-plate materials. Alternatively, as in pattern V, the plate materials of type A to type E may be determined at the same ratio.

2-2. Step of calculating the number of plate materials of each type Next, the process proceeds to step S2 in FIG. 1, and the number of plate materials of each type laid on the base surface is calculated based on the determined ratio. Here, in the present embodiment, as an example, a method for 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 members are laid on the base surface divided into 18 rows × 4 columns (see, for example, FIG. 5). Here, when the pattern I is selected as the ratio of the plate material, it is A type 60%, B type to E type 10%, and F type 0%. First, multiply the number of laying sheets by the ratio of each type of plate material.

  Specifically, the A-type main plate material is 72 × 60% and 43.2 sheets, and the B-type to E-type sub-plate materials are 72 × 10% and 7.2 sheets. The value of the number calculated here is not an integer. Therefore, in the present embodiment, the value of type A is set so that the value of the first to the decimal point of the calculated values of the numbers B to E is rounded down so that the total number of the plate members becomes the number of laying sheets (72 sheets). Increase (adjust) the value of the number of main plate materials.

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

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

  When using a random number table, for example, the row and column of the random number table are determined based on the date and time when this process is performed, and the random numbers arranged after that are determined from the numerical values of the random number table corresponding to the determined row and column. Are read in order. For example, in the present embodiment, the allocation start numerical value read from the rows and columns determined in the random number table is “70”, and the numerical values in the random number table are read sequentially from there (specifically, numerical values 69 and 25). , 11, 76,..., A number based on a random number is assigned to each of the A-type to E-type plate members.

  Next, different numbers are assigned to the laying positions at which the total 72 sheets of A to E types on the base surface are laid, depending on the number of laid boards. Specifically, as shown in FIG. 5, the serial numbers from 1 to 72 are assigned to the laying positions at which the respective plate members on the base surface are laid in order from the upper left as the assigned numbers.

  Next, the number of random numbers assigned to the plate material and the assignment number assigned to the laying position are associated with each other in the order of numbers to determine the laying position at which each type of plate material is laid on the base surface. Specifically, the random numbers assigned to the A-type to E-type plate members 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”, etc. in ascending order of numbers, and the plate materials to which the random numbers are assigned are “A type”, “A type”, “ A type ”,“ C type ”, etc., and in this order, random numbers are rearranged in correspondence with the types of plate materials.

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

  Here, as shown in FIG. 7 (a), (1) Class B sub-plate material with allocation numbers “15” and “16”, (2) Class D sub-plate material with allocation numbers “26” and “45”, ( 3) Class D sub-plate material with allocation numbers “30” and “47”, (4) Class C sub-plate material with allocation numbers “43” and “61”, and (5) Class E sub-plate materials 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 same type of sub-plate materials are not arranged at adjacent laying positions. Specifically, as shown in FIG. 7B, (1) the B-type sub-plate material with the allocation number “15” and the A-type main plate material with the allocation number “10” are switched. 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”; The A-type main plate material with the allocation number “17” is replaced. Further, (4) the C-type sub-plate material with the allocation number “61” and the B-type sub-plate material with the allocation number “37” are replaced, and (5) the D-type sub-plate material with the allocation number “63” and the allocation The A-type sub-plate material of number “9” is replaced.

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

  In this embodiment, as described above, the laying position of each type of plate material is determined using a random number table. However, for example, among the types A to E of the plate materials, the laying positions other than the laying positions (“1”, “18”, “55”, “72” in FIG. 5) of the corners of the base surface) are laid. The laying position of each plate member may be determined so that the plate member to be processed and at least one plate member adjacent to the plate member have different grain patterns. Thereby, it can avoid that adjacent board | plate materials become the board | plate material of the same kind altogether, and can suppress that the board | plate material of the same kind is laid unevenly.

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

  Thus, in this embodiment, the ratio of each type of plate material laid on the base surface is determined for a plurality of types of plate materials on which different types (A type to E type) of wood grain pattern are printed. Thus, the pattern of the entire board after laying can be selected according to preference.

  Also, based on the determined ratio, it is only necessary to calculate the number of each type of plate material and prepare a plate material corresponding to this number, so it is also possible to print and stock a wood grain pattern on the surface of the plate material in advance. it can.

  Moreover, in this embodiment, since the board | plate material which printed the wood grain pattern on the surface of the base material is manufactured by inkjet printing, a multi-product small lot production is possible and a wide variety of wood grain patterns can be produced. Therefore, the surface of the entire plate material (plate structure) can be applied to a handle according to preference on demand.

  Here, you may perform the process of step S1-S3 mentioned above using the construction system 1 shown in FIG. The construction system 1 includes an input device 11, an arithmetic device 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 includes the type of plate material and the ratio of each type of plate material shown in step S1, 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 input information can be input to the arithmetic unit 12.

  Based on the input information from the input device 11, the arithmetic device 12 calculates the number of each type of plate material shown in step S2, and determines the laying position of each plate material shown in step S3. Here, the storage device 13 has a pattern (see FIG. 2) corresponding to the ratio of each type of plate material shown in step S1, a random number table shown in step S3, and a grain pattern printed on each type of plate material. Information such as images is stored. In this way, the arithmetic device 12 reads the information from the storage device 13 based on the input information from the input device 11, thereby calculating the number of each type of plate material and performing the series of operations described above. This is done by calculation to determine the laying position of each plate material.

  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 device 12, and based on the input information from the input device 11. 12 shows the state (see FIGS. 7A and 7B) in which each type of plate material is laid at the laying position determined in FIG.

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

  As a result, before installing the plate material, the pattern of the entire plate material (plate structure) laid in advance can be confirmed, and further, each type until the entire plate material (plate structure) becomes the desired pattern. This can be confirmed by changing the ratio of the plate material.

  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 can be made without departing from the spirit of the present invention described in the claims. It can be changed.

  In this embodiment, the plate material to be constructed was a rectangular plate material, but may be, for example, a laminar type plate material, so long as it can be laid on the ground surface so that the plate materials are adjacent to each other. The shape is not particularly limited.
