Description

The present invention relates to a technique for precutting a flooring material to be laid on a floor according to the shape of the floor before carrying it to the laying site.

Various types of flooring materials are widely used as flooring materials used for the floors of general houses from various facilities including commercial facilities. The main flooring materials include resin flooring materials, wood flooring, stone materials, and ceramic flooring materials. Resin flooring materials include resin floor tiles, resin floor sheets, and tile carpets. The resin flooring material has enough flexibility to allow the flooring material to be bent manually. Resin flooring is easier to transport and carry in, and easier to cut, than wood flooring, stone, and ceramic flooring. Therefore, the resin flooring material has good workability even in a narrow space.

When laying flooring materials on the floor of rooms, bath / toilet units, etc., rectangular flooring materials are cut and laid according to the shape of the floor at the laying site. Skilled skill is required for this cutting work. However, the number of craftsmen with such skills is decreasing. Therefore, Japanese Patent Application Laid-Open No. 2018-82756 (Patent Document 1) describes that a tile carpet is provided by being cut and prepared in advance so that it can be easily laid on the floor without any skill. There is.

JP-A-2018-82756

In order to cut the floor material in advance (hereinafter referred to as pre-cutting) according to the shape of the floor before carrying it to the laying site, information indicating the exact shape of the floor is required. However, for example, it may be difficult to actually measure the shape of the floor from the viewpoint of work cost and the like. Flooring materials that have been precut without accurate floor shape information may not match the floor shape at the laying site.

Therefore, an object of the present invention is to provide a flooring material cutting system, a flooring material precutting method, and a program capable of precutting a flooring material based on the shape of the floor.

The floor material precutting system according to one aspect of the present invention includes a reception unit that accepts input of floor specific information that specifies the floor on which the floor material is laid, and floor shape data that indicates the shape of the floor specified by the floor specific information. The floor data acquisition unit for acquiring the floor material data acquisition unit, the floor material data acquisition unit for acquiring the floor material data indicating the dimensions of the floor material laid on the floor, and the one or more of the dimensions indicated by the floor material data. A cutting line determination unit that determines the cutting line of the one or a plurality of floor materials when the floor material is laid on the floor having the shape indicated by the floor shape data and generates cutting line data indicating the cutting line, and the cutting line. The output unit that outputs data, the cutting line of the floor material determined by the cutting line determination unit, or the cut data indicating the cutting line when the floor material or pattern is actually cut according to the floor, is used as the floor material. It is provided with a storage unit that records in the recording unit in association with the floor identification information that specifies the floor to be laid. When the cut data corresponding to the received floor identification information is recorded in the recording unit, the cutting line determination unit generates the cutting line data using the cut data recorded in the recording unit. do.

According to the above configuration, it is possible to generate a cutting line of the floor material to be applied to the floor specified by the floor specific information, and it is possible to associate the past cutting line with the floor specific information and store it as cut data. When determining the cutting line, if there is cut data corresponding to the target floor, the cutting line can be determined by using this. The cut data indicates the cutting line of the flooring material generated in the past or the cutting line of the flooring material or the pattern paper actually cut according to the floor. Therefore, the accuracy of the cutting line can be improved by using the cut data. This promotes the generation of cutting lines for flooring materials, the accumulation of actual data on cutting lines, and their use. As a result, the flooring material can be precut based on the shape of the floor.

The floor material data acquisition unit may further acquire physical property data of the floor material laid on the floor, and the cutting line determination unit may modify the cutting line data using the physical property data. This makes it possible to generate more accurate cutting data. The physical property data may be, for example, data indicating the material of the flooring material or a value indicating the property of the material of the flooring material.

The cutting line determination unit is the floor when the floor area indicated by the floor shape data is superposed in the area where one or a plurality of floor materials having the dimensions indicated by the floor material data are arranged. A line corresponding to the edge line of the floor area overlapping the material may be determined as the cutting line. That is, the cutting line can be determined based on the edge line of the floor area that overlaps the floor material. Thereby, the cutting line of the floor material can be determined based on the shape of the floor. The line corresponding to the edge line of the floor area includes a line determined based on the edge line as in the following example.

In the cutting line determination unit, at least a part of the cutting line is a floor area indicated by the floor shape data in an area in which one or a plurality of floor materials having the dimensions indicated by the floor material data are arranged. May be set at a position deviated by a certain amount from the edge line of the area of the floor that overlaps the floor material when the flooring materials are overlapped.

In this way, when determining the cutting line, by shifting the cutting line of the floor material with respect to the edge of the floor shape obtained from the floor shape data, the cutting line considering the difference from the actual floor shape can be obtained. Can be set.

For example, the cutting line determination unit places at least a part of the cutting line in a region in which one or a plurality of floor materials having the dimensions indicated by the floor material data are arranged, and the floor is indicated by the floor shape data. The area may be set to the outside by a certain amount from the edge line of the area of the floor that overlaps the floor material when the areas of the above are overlapped. Thereby, the area of the floor material can be cut so as to be larger than the area of the floor surface. In this case, at the laying site, at least a part of the edge of the flooring material can be cut to fit the edge of the floor surface. That is, the floor material can be finely adjusted according to the floor surface.

Further, at least a part of the cutting line is arranged so that the floor area indicated by the floor shape data is overlapped in the area where one or a plurality of floor materials having the dimensions indicated by the floor material data are arranged. It may be set inward by a certain amount from the edge line of the area of the floor that overlaps the floor material in the case. Thereby, the area of the floor material can be cut so as to be smaller than the area of the floor. In this case, at the laying site, the gap between the floor material and the floor surface can be adjusted with other members such as baseboards.

The cutting line determination unit may determine the arrangement of the floor area in the area where the one or a plurality of floor materials are arranged based on the input of the user. In this case, the cutting line is determined based on the edge line of the floor area arranged in the flooring area based on the user's input. Thereby, the user can adjust the arrangement of one or more flooring materials with respect to the area of the floor so that the flooring material can be easily arranged, for example, at the laying site.

Based on the input of the user, the cutting line determination unit places at least a part of the cutting line in the area where one or a plurality of flooring materials having the dimensions indicated by the flooring material data are arranged, and the floor shape data. When the floor areas indicated by are overlapped with each other, the floor area may be offset from the edge line of the floor area that overlaps the floor material. As a result, the user can set an appropriate cutting line in consideration of, for example, the difference between the actual floor shape and the floor material, the work efficiency at the site, and the like. For example, the cutting line determination unit accepts at least one of the designation of the portion of the edge line of the floor area overlapping the floor material to shift the cutting line, the designation of the shift direction, and the designation of the shift amount from the user. You may.

The cutting line determination unit determines a reference line in the floor area indicated by the floor shape data, and based on the arrangement of the plurality of floor materials with respect to the floor area determined based on the reference line. It may be configured to determine the cutting line. This makes it possible to determine a reference line as a reference when arranging a plurality of flooring materials on the floor. Therefore, the reference line can be set at an appropriate position for the laying work at the site. The reference line may be determined based on the input of the user. In this case, the user can determine the reference line according to the shape of the floor.

The flooring pre-cutting system may further include a floor design data acquisition unit that acquires floor design data related to the construction of the flooring material on the floor. The cutting line determination unit may determine the cutting line using the floor design data.

The floor design data may include edge construction data indicating the construction of the flooring material at the edge of the floor. In this case, when the cutting line determination unit arranges the floor area indicated by the floor shape data in an overlapping area in the area where one or a plurality of floor materials having the dimensions indicated by the floor material data are arranged. The position of the cutting line with respect to the line corresponding to the edge line of the floor area overlapping the floor material can be determined according to the construction of the floor material at the edge of the floor indicated by the edge construction data.

The floor design data may include floor unevenness data indicating a line of at least one edge of the concave portion and the convex portion of the floor.

(Floor material)
In the present specification, the flooring material includes flooring materials laid from various facilities such as commercial facilities to rooms, bathrooms, corridors, balconies, etc. of buildings such as general houses. Flooring materials include, for example, those formed of organic materials such as resin and wood, and inorganic materials such as ceramics and stones. The main flooring materials include resin flooring materials, carpets, wood flooring, stone materials, and ceramic flooring materials. The material of the flooring material is not particularly limited, but since the inorganic material is too hard and the wood has a large dimensional change due to humidity, a resin flooring material mainly made of resin is preferably used in the present invention among organic materials. Be done. Examples of resin flooring materials mainly made of resin include carpets such as tile carpets and roll carpets, and various vinyl flooring materials including floor tiles and floor sheets specified in JIS A 5705.

Resin flooring has flexibility to the extent that the flooring can be manually bent as compared with flooring made of wood flooring, stone, ceramic or the like. Therefore, the resin flooring material is easy to carry and carry in, and is also easy to cut. The resin flooring material has good workability and can be installed even in a narrow space. Examples of resin flooring materials include resin floor tiles and resin floor sheets. The resin floor tile is usually a plate-shaped resin floor material having a side of 400 to 1000 mm. The resin flooring sheet is a rectangular resin flooring material whose length in one direction is sufficiently longer than the length in the other direction (the other direction is orthogonal to one direction). For example, the length of the resin floor sheet in one direction is twice or more, preferably four times or more the length in the other direction. The resin floor sheet is usually wrapped in a roll and used for storage and transportation, and is cut into a desired shape and used at a construction site.

Examples of the method of constructing the resin flooring material include an adhesive type and a laying type. Adhesive type resin flooring can be firmly fixed to mortar or concrete surface, and it is hard to peel off, so it has excellent durability. On the other hand, the flooring type resin flooring can be used for the purpose of simple remodeling, remodeling, advertising, etc. by sticking them on the existing floor. The stationary type resin flooring does not need to be completely reattached, for example, when repair is required at the time of remodeling. It is also possible to adopt a partial replacement method in which the sheet at the part requiring repair is peeled off and replaced with a new sheet.

The resin of the resin flooring material may be non-foamed or may be foamed. When the resin layer is formed of foamed resin, cushioning property with good foaming can be imparted to the floor material. A thermoplastic resin is generally used as the resin component of the resin flooring material. Examples of the thermoplastic resin include vinyl chloride resin; olefin resin; vinyl acetate resin such as ethylene-vinyl acetate copolymer; acrylic resin such as ethylene-methacrylate resin; amide resin; ester resin; olefin-based elastomer and styrene-based elastomer. Various elastomers such as various elastomers; rubber and the like can be mentioned. These can be used alone or in combination of two or more as the resin component of the flooring material.

Further, the resin flooring material may contain various additives in addition to the resin. As the additive, conventionally known ones can be used, and examples thereof include fillers, plasticizers, flame retardants, stabilizers, antioxidants, lubricants, colorants, and foaming agents. In addition to the main component, another resin may be laminated and used for the resin flooring material. Examples of the resin used as these other components mainly include an ultraviolet curable resin, hard vinyl chloride, and a resin other than vinyl chloride. By laminating these resins on the surface layer, excellent properties such as durability, abrasion resistance, antifouling property, and anti-slip property can be imparted.

Widely used resin flooring materials include vinyl flooring materials containing vinyl chloride resin as a main resin component. Vinyl flooring is made of vinyl chloride resin, which has excellent flexibility, so it has excellent durability, and since it can be bent and rolled, it is easy to transport and carry in, and it is easy to install even in narrow places. good. In addition, since the vinyl chloride resin is also excellent in flexibility, it has a good walking feeling, is easy to cut at the time of construction, and can be easily cut into a complicated shape. Moreover, since it can be applied to the floor surface (construction surface on which the floor material is laid) while being curved, it is easy to handle. Moreover, the vinyl chloride resin is inexpensive, and it is easy to manufacture a flooring material using the vinyl chloride resin.

Examples of the vinyl-based floor sheet without a foam layer include a single-layer vinyl floor sheet and a multi-layer vinyl floor sheet. Vinyl-based flooring materials include vinyl chloride resins such as vinyl chloride resin and vinyl chloride-vinyl acetate copolymer resin, plasticizers and stabilizers such as dioctyl phthalate and dinonyl phthalate, and fillers, colorants, and foams as necessary. Includes agents, woven fabrics, non-woven fabrics, recycled materials, etc.

As the additive, conventionally known ones can be used, and examples thereof include fillers, plasticizers, flame retardants, stabilizers, antioxidants, lubricants, colorants, and foaming agents. The filler is not particularly limited, and examples thereof include calcium carbonate, calcium oxide, barium carbonate, magnesium hydroxide, aluminum hydroxide, clay, talc, and mica.

The plasticizer is not particularly limited, and examples thereof include dioctyl phthalate (DOP), dibutyl phthalate (DBP), and butyl octyl phthalate (BOP).

Examples of the woven fabric include those containing glass fiber, synthetic fiber, natural fiber and the like as material components. Examples of recycled materials include nonconforming products generated in the production stage of vinyl flooring materials; materials generated in the distribution stage and scraps, surplus materials, etc. generated during construction; used vinyl flooring materials and the like.

The reception unit 11 receives input of floor identification information for specifying the floor on which the floor material is laid from the user. The floor identification information may specify, for example, at least one of the floor location and the floor type. Examples of floor-specific information that identifies the location of the floor include information that identifies buildings, floors, and areas. Examples of floor identification information for specifying the floor type include those that specify the model number of a unit such as a bath or toilet having a floor on which flooring is laid, or the type of room. The reception unit 11 may accept the input of the floor identification information data from the user, or may acquire the floor identification information data recorded at the place designated by the user of the recording unit 2.

The floor data acquisition unit 12 acquires floor shape data indicating the shape of the floor specified by the floor identification information received by the reception unit 11. The floor shape data can be data indicating the shape of the edge (contour) of the area where the floor material is laid. The floor shape data also includes information indicating the dimensions of the area where the flooring material is laid. The floor data acquisition unit 12 may, for example, accept input of floor shape data from the user, or may acquire floor shape data corresponding to the floor identification information from the recording unit 2. In the recording unit 2, for example, various floor shape data of the floor can be recorded in association with the floor identification information.

The floor material data acquisition unit 13 acquires floor material data indicating the dimensions of each floor material to be laid on the floor. The floor material data can be data indicating the dimensions of each side of the edge (contour) of the area indicated by one floor material. For example, when the flooring material is square or rectangular, the data indicating the vertical dimension and the horizontal dimension of the flooring material can be used as the flooring material data. The flooring data acquisition unit 13 may, for example, accept input of flooring material data from the user, or may acquire flooring material data from the recording unit 2. In the recording unit 2, for example, flooring data of various flooring materials can be recorded in association with the flooring material identification information.

As a result, cutting line data is generated. That is, the cutting line determination unit 14 generates cutting line data using the floor shape data acquired by the floor data acquisition unit 12 and the floor material data acquired by the floor material data acquisition unit 13.

As an example, the cutting line determination unit 14 is a floor when the floor area indicated by the floor shape data is overlapped in an area in which one or a plurality of floor materials having the dimensions indicated by the floor material data are arranged. The line on the flooring corresponding to the edge line of the region can be determined as the cutting line. In this case, at least a portion of the cutting line may be offset from the edge line of the floor area.

Further, when the cut data corresponding to the floor identification information received by the reception unit 11 is recorded in the recording unit 2, the cutting line determination unit 14 uses the cut data recorded in the recording unit 2 for cutting. Line data can be generated. The cut data is, for example, a cutting line determined by the cutting line determination unit 14 for the same floor and floor material in the past, or a cutting line when the floor material or pattern is actually cut according to the floor. It is the data which shows.

The cutting line determination unit 14 obtains the cut data acquired from the recording unit 2 for the cutting line data generated based on the floor shape data acquired by the floor data acquisition unit 12 and the floor material data acquired by the floor material data acquisition unit 13. It may be corrected by using. Alternatively, the cutting line determination unit 14 may generate the cutting line data using the cut data acquired from the recording unit 2 instead of generating the cutting line data based on the floor shape data and the floor material data.

The cut data is recorded in the recording unit 2 by the storage unit 16 in association with the floor identification information. The storage unit 16 may record the cutting data generated by the cutting line determination unit 14 in the recording unit 2 in association with the floor identification information that is the basis of the generation. Further, the storage unit 16 may record the data indicating the cutting line, that is, the cutting line of the floor material cut by the cutting machine 3 in the recording unit 2 in association with the floor identification information for specifying the floor on which the floor material is laid. good. Alternatively, the storage unit 16 acquires the actual data indicating the actual cutting line of the floor material input from the cutting line data input system 4 at the laying site together with the floor identification information for specifying the floor on which the floor material is laid. , The cut data may be recorded in the recording unit 2 in association with the floor identification information. The data format of the floor specific information recorded in the recording unit 2 may be the same as or different from the data format of the floor specific information received from the user by the reception unit 11.

The output unit 15 outputs the cutting line data generated by the cutting line determination unit 14. The output unit 15 outputs the cutting line data to, for example, the cutting machine 3. The cutting machine 3 can cut the flooring material along the line indicated by the cutting line data. In this case, the output unit 15 can output the cutting data in a format that can be processed by the control device of the cutting machine 3. Alternatively, the output unit 15 may output a command for cutting the flooring material along the cutting line to the cutting machine 3. That is, the floor material precutting system 1 may be configured to control the cutting machine 3.

The flooring precutting system 1 is composed of a computer equipped with a processor and a memory.

In the example shown in FIG. 4, data indicating the floor size (length, width, thickness), weight, product type, material, and location for storing the floor material data is recorded in association with the product number of the floor material.

The floor material pre-cutting system 1 may record in the recording unit 2 information that associates the floor identification information input by the user in S1 with the product number of the floor material input in S3. For example, as shown in FIG. 5, the floor ID specified from the information input by the user in S1 can be associated with the product number input by the user in S3 and recorded in the recording unit 2. As a result, it is possible to efficiently manage information indicating which flooring material is laid in which place.

The cutting line determination unit 14 determines the cutting line of the floor material to be laid on the floor by using the floor shape data acquired in S2 and the floor material data acquired in S3 (S4). The cutting line determination unit 14 overlaps each floor material when, for example, a floor having the shape indicated by the floor shape data is superposed on a region in which one or a plurality of floor materials having the dimensions indicated by the floor material data are arranged without gaps. The cutting line can be determined based on the line on the edge of the floor.

FIG. 7 is a diagram showing an example of the floor shape indicated by the floor shape data. FIG. 7 shows the shape of the floor of the unit bath with a toilet. In FIG. 7, the area A1 indicated by dots is the area where the flooring material is laid. In this example, the flooring material laid on the floor needs to be provided with a drainage port hole A1a and a toilet bowl hole A1b. FIG. 8 is a diagram showing a case where the floor having the shape shown in FIG. 7 is stacked in the area of one floor material (floor sheet). In the example shown in FIG. 8, the area of the flooring material is indicated by the broken line B1.

In the example shown in FIG. 8, the cutting line determination unit 14 can determine the line of the edge of the floor overlapping the floor material inside the area of the floor material indicated by the broken line B1, that is, the line indicated by the solid line A11 as the cutting line. .. Here, the floor edge line also includes the edge of the hole for the toilet bowl and the edge of the hole for the drain. Further, the cutting line determination unit 14 includes a line (a line indicated by a long-dotted chain line) C1 connecting the outer peripheral edge of the floor and the edge of the hole in the cutting line. This makes it possible to determine the flooring cutting line so that the flooring can be laid around an isolated area where the flooring cannot be laid, which is caused by toilet bowls, pillars, furniture, and the like.

In the above example, the line of the edge of the floor that overlaps the floor material is used as the cutting line. On the other hand, a line separated by a certain distance from the line of the edge of the floor overlapping the floor material can be used as the cutting line.

FIG. 9 is a diagram showing an example in which a cutting line is set to the outside by a certain amount from the line of the edge of the floor that overlaps the area of the flooring material. In FIG. 9, the cutting line indicated by the alternate long and short dash line C2 is arranged outside by a certain amount with respect to the floor edge line indicated by the solid line A11.

FIG. 10 is a diagram showing an example in which a cutting line is set inward by a certain amount from the line of the edge of the floor that overlaps the area of the flooring material. In FIG. 10, the cutting line indicated by the alternate long and short dash line C2 is arranged inside by a certain amount with respect to the line of the edge of the floor indicated by the solid line A11.

It is also possible to shift part of the cutting line from the floor edge line by a certain amount and align the other part with the floor edge line. FIG. 11 is a diagram showing an example in which a part of the cutting line is shifted by a certain amount from the line of the edge of the floor. In FIG. 11, the cutting line indicated by the alternate long and short dash line C3 is arranged outside by a certain amount with respect to the line of the edge of the floor indicated by the solid line A11. As shown in the example shown in FIG. 11, the cutting line is aligned with a pair of opposite sides of the outer peripheral edge line of the floor, and the other side is set at a position deviated by a certain amount from the edge line. can do. In addition, the cutting line can be arranged at a position deviated by a certain amount from the edge of the floor in the portion including the curved edge of the floor, such as the edge of the hole of the toilet bowl.

Further, although not shown, in one flooring material, a part of the cutting line is shifted outward by a certain amount with respect to the floor edge line, and the other part is shifted outward by a certain amount with respect to the floor edge line. You may shift it inward. That is, a portion shifted outward and a portion shifted inward with respect to the line of the edge of the floor may be mixed in the cutting line. For example, the cutting line determination unit 14 may determine the cutting line by shifting the outer peripheral edge of the floor inward and the edge of the hole outward.

The portion and the amount of the cutting line to be shifted from the line of the edge of the floor may be automatically determined by the cutting line determining unit 14 based on a preset standard. Alternatively, based on the user's input, at least one of a portion, a direction of shift, and an amount of shift of the cutting line from the line of the edge of the floor can be determined. For example, as shown in FIGS. 8 to 11, an image in which the floor material area and the floor area are overlapped is displayed on the screen of the display, and the user shifts the cutting line from the edge of the floor on the screen. It may be possible to specify. For example, it is possible to receive input from the user of the start point and the end point of the portion where the cutting line is to be shifted from the edge of the floor. Further, an input for designating a relative position between the floor material area and the floor area may be accepted from the user.

The cutting line determination unit 14 may determine the amount of the cutting line to be displaced from the edge of the floor based on the physical property data of the floor material obtained from the floor material data. For example, the amount of shift can be determined based on the material of the flooring material or the physical property value such as the coefficient of thermal expansion. This makes it possible to determine a cutting line that makes it easier for the flooring material to fit the floor, depending on the physical characteristics of the flooring material.

Further, the cutting line determining unit 14 may determine the amount of shifting the cutting line according to the floor portion obtained from the floor shape data. For example, the amount of shift can be increased at the outer peripheral edge of the floor, and the amount of shift can be reduced at the edge of the hole. This facilitates construction according to the part of the room, such as treating the outer peripheral edge of the floor with a baseboard and treating the edge of the hole with a sealing material.

FIG. 12 is a diagram showing an example in which a floor area is overlapped in an area in which a plurality of floor materials are arranged. In the example shown in FIG. 12, the edges of the plurality of flooring materials (for example, tile carpet) are indicated by the broken lines B2 and B2a, and the edges of the floor area are indicated by the solid line A2. One reference line along the edge of the flooring is indicated by a thick dashed line B2a. The reference line is a line set at the laying site when laying the flooring material. At the laying site, flooring will be lined up along the reference line. As shown in FIG. 12, the cutting line determination unit 14 superimposes the edge of the floor material including the reference line and the edge of the floor area on the screen, and inputs the relative position of the reference line to the floor area as input by the user. It can be adjusted accordingly. This allows the user to arbitrarily set a reference line for the floor on which the flooring material is laid. In the example shown in FIG. 12, similarly to the above example, a line corresponding to the line of the edge of the floor overlapping the floor material can be determined as the cutting line.

Although FIG. 12 shows an example in which one reference line is in the horizontal direction, a total of two reference lines may be added by adding a vertical reference line orthogonal to the horizontal reference line. In particular, for tile carpets and floor tiles, it is preferable to set two reference lines in the vertical and horizontal directions because the construction can be performed neatly. For example, the reference line is used in the field to determine the position of the flooring to be laid first. As an example, the position of the flooring material to be laid first can be aligned with the position of the intersection of the two orthogonal reference lines, and the orientation of the flooring material to be laid first can be aligned with the two reference lines.

As a general rule, the reference line can be set to pass through the center of the floor of the room. Further, when a plurality of flooring materials are applied to the floor surface, the flooring material near the wall is cut along the outer periphery of the floor. Therefore, the reference line is set so that the dimensions of the flooring material cut along the outer circumference of the floor (for example, the width or area of the flooring material in the direction of the reference line) satisfy a predetermined condition. Is preferable. For example, a reference line can be set so that the flooring material near the wall of the floor surface does not contain a flooring material having a size of 1/3 or less of the flooring material before cutting. As a result, small pieces of flooring material are not installed on the edge of the floor surface, and a beautiful finish can be obtained. In this way, the dimensions of the flooring material at the edge of the floor surface can be adjusted by the position of the reference line. The cutting line determination unit 14 may automatically set such a reference line according to floor shape data, floor material data, and predetermined conditions, or may perform such setting based on user input.

With reference to FIG. 2 again, in S5, the storage unit 16 associates the cutting line data indicating the cutting line determined in S4 with the floor identification information input in S1 and records it as cut data in the recording unit 2. Record. FIG. 6 is a diagram showing an example of data for associating floor identification information with cut data. In the example shown in FIG. 6, the floor ID and the storage location of the cut data indicating the cutting line of the floor material laid on the floor specified by the floor ID are recorded in association with each other.

The cut data accumulated in this way may be used in the cutting line determination process of S4 described above. In S4, the cutting line determination unit 14 may execute a process of determining whether or not the cut data corresponding to the floor specified by the floor identification information input in S1 is recorded in the recording unit 2. For example, the cutting line determination unit 14 may search for floor identification information in which at least one of the floor location and type specified in the input floor identification information matches. When the corresponding floor identification information is extracted, the cut data corresponding to the extracted floor identification information is acquired from the recording unit 2. The cutting line determination unit 14 first searches for floor identification information that matches all of the floor identification information input to the user, and if not found, the floor identification information that matches the floor type among the input floor identification information. Can be searched. Thereby, for example, it is possible to acquire the cut data of the unit bath of the same type or the room of the same type as the floor to which the flooring material is laid.

If the corresponding cut data has already been recorded in the recording unit 2, the cutting line determination unit 14 can determine the cutting line using the cut data. The cutting line determination unit 14 may use the acquired cut data as it is as the cutting line data. Alternatively, the cutting line determination unit 14 may display the cutting line indicated by the acquired cut data on the floor material area and the floor area on the screen and accept editing from the user. Further, the cutting line determination unit 14 displays on the screen the cutting line of the cut data acquired from the recording unit 2 and the cutting line determined based on the floor shape data acquired in S2 and the floor material data acquired in S3. You can also let the user choose which one to use. By using the cut data, the cutting line determining unit 14 can determine a cutting line that makes it easier for the flooring material to fit the floor.

In S6 of FIG. 2, the output unit 15 outputs the cutting line data generated in S4 to the cutting machine 3 (S6). The cutting machine 3 cuts the floor material at the cutting line showing the cutting line data. As a result, the flooring material is precut. The pre-cut flooring is transported to the laying site.

(Collection of cutting information at the laying site)
At the laying site, if the pre-cut flooring does not fit the floor, the flooring is further cut and adjusted. In the present embodiment, the cutting line data input system 4 (see FIG. 1) for collecting information on the cutting line for cutting the flooring material at the laying site is provided.

The cutting line data input system 4 may include a mobile terminal that accepts input of an image of a flooring material, a measurement result, or cutting information from a user at a laying site. The mobile terminal can have a built-in or connectable camera or other sensor (measuring device) that obtains information on the flooring cutting line at the laying site.

For example, it is possible to analyze an image obtained by taking a picture of the flooring material after cutting at the laying site with a camera and obtain data showing a cutting line of the flooring material at the laying site. Alternatively, by inputting the dimensions cut by the user at the laying site into the mobile terminal, it is possible to obtain data indicating the cutting line of the flooring material at the laying site.

The data indicating the floor material cutting line at the laying site is supplied to the floor material pre-cutting system 1 together with the floor identification information for specifying the floor at the laying site. The supplied data indicating the cutting line of the flooring material at the laying site is recorded in the recording unit 2 in association with the floor identification information as cut data by the storage unit 16. The flooring pre-cutting system 1 may analyze data obtained at the laying site, such as an image of the flooring material and measured values, to generate cutting line data.

The cutting line data input system 4 supplies information on the cutting line by cutting the flooring material at the laying site to the recording unit 2. Therefore, the cutting line determination unit 14 can determine the cutting line based on the actual cutting results at the laying site. As a result, it is possible to determine a cutting line in which the floor material is more likely to fit the floor.

(Collection of floor information at the laying site)
A measurement system 5 for measuring the shape of the floor may be provided at the laying site. The measuring system 5 has a measuring device for measuring the floor. The measuring instrument may, for example, calculate the shape and dimensions of the floor from an image taken by a camera. Alternatively, the measuring instrument may be one that acquires the dimensions of the floor using a laser distance measuring meter. The measuring instrument may be, for example, a dedicated device for measurement, or may be realized as a part of the function of a portable general-purpose computer such as a smartphone with a camera.

The floor measurement data obtained by the measuring instrument of the measurement system 5 is supplied to the floor material precutting system 1 together with the floor identification information for specifying the floor to be measured. The supplied floor measurement data is recorded in the recording unit 2 as floor shape data in association with the floor identification information. The measurement system 5 supplies the floor shape data obtained by the measurement at the laying site to the recording unit 2. Therefore, it becomes possible to determine the cutting line using more accurate floor shape data.

(Modification example)
FIG. 13 is a diagram showing a modified example of the flooring precutting system. In the example shown in FIG. 13, in addition to the configuration shown in FIG. 1, the floor material precutting system 1a includes a floor design data acquisition unit 21, a construction support data generation unit 22, a manufacturing cooperation data generation unit 23, and a learning unit 24. Further prepare.

(Example of floor design data and its usage example)
The floor design data acquisition unit 21 acquires the floor design data. The floor design data includes information on the construction of the floor shape data and other floor material data. The floor design data acquisition unit 21 can acquire floor design data related to the construction of the floor material on the floor specified by the floor identification information received by the reception unit 11. In the recording unit 2, for example, floor design data of various floors can be recorded in association with floor identification information. The floor design data may be, for example, data acquired from a database used in Building Information Modeling (BIM). In addition, the floor design data acquisition unit 21 can accept input of floor design data from the user. The storage unit 16 may record the floor design data in the recording unit as cut data in association with the cutting line data or the floor identification information. By accumulating the floor design data as cut data, information on floor construction can be used in the cutting line determination process using the cut data. Therefore, it is possible to generate cutting line data suitable for on-site construction.

(Construction information on the edge of the floor and an example of processing using it)
The floor design data may include, for example, edge construction data indicating the construction of the flooring material at the edge of the floor. There are various methods for constructing flooring materials at the edges of the floor. In addition to the construction that aligns the edge of the floor with the edge of the flooring material, for example, there are the following construction methods. As shown in FIG. 14A, a skirting board 40 may be provided on the wall 50 at the edge of the floor. In the construction order, for example, after laying the flooring material 30, the baseboard 40 is attached to the wall 50 so as to cover the edge of the flooring material 30. The edges of the flooring material 30 are laid with a predetermined space W0 or without a predetermined space between the floor material 30 and the wall 50. Generally, the lower end of a skirting board is often curved, and the thickness dimension of the lower end of the skirting board 40 is W1. By setting W0 <W1 when determining the cutting line, the distance W0 between the floor material 30 and the wall 50 at the end can be hidden by the baseboard 40, and a clean and quick finish can be achieved.

As shown in FIG. 14B, a waterproof member 41 such as a sealing material may be provided between the wall 50 and the edge of the floor material 30. In this case, the edges of the flooring material 30 are laid with a predetermined interval W2 from the wall 50. As the sealing material, an amorphous sealing that changes to an elastic body when cured, a standard sealing that closes a gap with a member or the like, and the like are preferably used. When determining the cutting line, by setting the optimum interval W2 according to the type of sealing material, on-site construction can be easily performed.

As shown in FIG. 15, there is a case where the floor material 30 is wound up on the wall 50 at the edge of the floor. In this case, an end treatment member 42 such as a sealing material or a molding material may be provided at the end of the rising portion of the floor material 30. Alternatively, a parting material may be provided at the end of the floor material 30.

As another example, at the edge of the floor of the grating 43 shown in FIG. 16 and the groove 45 shown in FIG. 17, a waterproof member 41 such as a sealing material, a molding material, or putty is provided at the end of the floor material 30. In some cases. In the example shown in FIG. 16, the waterproof member 41 is provided between the grating frame 44 and the floor material 30.

The edge construction data may include information indicating a method of constructing the flooring material at the edge of the floor, such as a skirting board, a stand-up, or a seal. The edge construction data may include information indicating dimensions in construction (for example, dimensions from the edge of the floor to the edge of the flooring). For example, in the example shown in FIGS. 14A and 14B, the thickness W1 of the skirting board and the width W2 of the waterproof member 41 may be included in the edge construction data. Further, the height H1 of the rising portion in the rising construction shown in FIG. 15, and the widths W3 and W4 of the waterproof member 41 shown in FIGS. 16 and 17 may be included in the edge construction data. In this way, if the edge construction data includes information indicating the construction method of the floor material at the edge of the floor, such as a baseboard, a start-up, or a seal, the edge of the floor material is positioned based on the construction method. The cutting line can be determined so that the portions are arranged. Therefore, efficient and accurate construction is possible.

The cutting line determination unit 14 can determine the cutting line by using the edge construction data. For example, the cutting line determination unit 14 is a flooring material when the flooring area indicated by the floor shape data is overlapped in an area in which one or a plurality of flooring materials having the dimensions indicated by the flooring material data are arranged. The position of the cutting line (for example, the amount of deviation) with respect to the line corresponding to the edge line of the floor area overlapping the floor can be determined based on the edge construction data.

Whether the cutting line of the flooring material is shifted outward, inward, or aligned with respect to the edge of the floor can be determined based on the edge construction data. Further, the amount of deviation in that case can be determined based on the edge construction data.

When the floor material is cut smaller than the floor surface, the amount of deviation from the edge of the floor surface may be within a range that can be hidden by a skirting board or a waterproof member. For example, in the case shown in FIG. 10, the distance between the floor edge line A11 overlapping the flooring area and the cutting line C2 shifted inward can be determined based on the edge construction data. .. In this case, the above distance is determined using, for example, the thickness W1 of the skirting board and the widths W2 to W4 of the waterproof member shown in FIGS. 14, 16 and 17, as the edge construction data. Can be done.

Further, when the floor material is cut to be larger than the floor surface, the amount of deviation from the edge of the floor surface can be set to a dimension corresponding to the rising height. For example, in the case shown in FIG. 9, the distance between the floor edge line A11 overlapping the flooring area and the cutting line C2 shifted to the outside can be determined based on the edge construction data. .. In this case, the above distance can be determined by using, for example, the height H1 of the raised portion when the floor material is raised and constructed, which is shown in FIG. 15, as the edge construction data.

In this way, by determining the relative position of the floor material cutting line with respect to the edge of the floor surface using the edge construction data, it is possible to determine a cutting line suitable for the construction of the edge portion of the floor material. Therefore, efficient and accurate construction is possible.

(Construction information on the edge of the floor and an example of processing using it)
The floor design data may include floor unevenness data indicating at least one of the concave and convex portions of the floor. Here, the concave portion indicated by the floor unevenness data includes, for example, a groove or a hole such as a drain port. The protrusions include, for example, floor protrusions, pillars, or installations provided on the floor. These recesses or protrusions are areas where the flooring material is not laid. The floor unevenness data may include data indicating the shape of the edge of the concave portion or the convex portion. For example, in the example shown in FIG. 7, data indicating the shape of the edges of the drain port (A1a) and the toilet bowl (A1b) may be acquired as floor unevenness data.

The cutting line determination unit 14 may determine the cutting line based on the floor unevenness data. For example, the cutting line determination unit 14 can add a cutting line corresponding to the edge of the concave or convex portion indicated by the floor unevenness data to the cutting line determined based on the edge of the floor indicated by the floor shape data. As a result, it is possible to generate a cutting line for cutting the floor material in a shape that avoids the concave and convex portions of the floor. By determining the cutting line using the floor unevenness data, it is possible to determine the cutting line so that the edge of the floor material matches the unevenness of the floor such as grooves, holes, protrusions, pillars or installations on the floor. can. As a result, the construction efficiency at the site can be improved.

(Example of joint information and processing using it)
The floor design data may include joint data indicating the joints of the floor. For example, when the floor is constructed by laying a plurality of concrete panels (plate materials), or when a double floor is composed of a plurality of floor raising members, there is a joint at the boundary between the plurality of members constituting the floor. The joint data includes information indicating the position of the joint on the floor. The cutting line determination unit 14 can determine a cutting line that is less likely to overlap with the floor joint indicated by the joint data.

For example, in the example shown in FIG. 12, when determining the relative position of the reference line B2a with respect to the floor edge A2, the position of the reference line B2a can be determined so that the overlap between the cutting line and the floor joint is not reduced. can. For example, the cutting lines may be determined so that the cutting lines parallel to each other and the joints on the floor do not overlap. Alternatively, in the example shown in FIG. 12, the joints on the floor may be displayed. When the cutting lines parallel to each other and the joints on the floor overlap, information may be output to alert the user. As a result, the joints of the flooring material and the joints of the flooring material can be allocated so as not to overlap. By determining the cutting line using the joint data in this way, it is possible to efficiently construct the floor material so as to reduce the overlap between the floor joint and the floor material joint at the construction site.

(Information on edge treatment of flooring materials and examples of treatment using it)
The floor design data may include construction data between floor materials indicating construction between a plurality of floor materials. The construction data between flooring materials may be, for example, data indicating seam processing between a plurality of flooring materials. For example, when welding a seam between flooring materials using a welding rod, it is necessary to cut the end portion of the flooring material so that the cross section of the seam is V-shaped or U-shaped. In such a case, the cutting line determination unit 14 can generate end processing data instructing the processing of the end portion of the flooring agent based on the construction data between floor materials. That is, the cutting line determination unit 14 may generate end processing data indicating the processing of the end portion of the floor material in the determined cutting line based on the construction between the floor materials indicated by the construction data between floor materials. .. The storage unit 16 may record the end processing data in the recording unit as cut data in association with the cutting line data or the floor identification information.

The floor design data may include appearance design data indicating the appearance design of the flooring material. For example, by arranging a plurality of flooring materials having different appearances on the floor, a predetermined appearance design can be applied to the floor. The appearance design data may be data representing the color or pattern of the floor on which the flooring material is laid. The appearance design data may be data showing the shapes and arrangements of a plurality of flooring materials having different appearances.

The cutting line determination unit 14 can determine the cutting line based on the appearance design data. For example, a cutting line for each of a plurality of flooring materials having different appearances can be determined based on the appearance design data. By laying a plurality of flooring materials with different appearances cut on the cutting line on the floor in combination at the construction site, the design indicated by the appearance design data can appear on the floor.

(Example of construction support data generation unit)
The construction support data generation unit 22 generates construction support data that supports the construction of laying the flooring material cut at the cutting line indicated by the cutting line data on the floor. The construction support data is generated based on the cutting line data generated by the cutting line determination unit 14. The storage unit 16 may record the construction support data in the recording unit as cut data in association with the cutting line data or the floor identification information.

The construction support data may include, for example, reference line data indicating a reference line on which the cutting line data is determined. The reference line data may include, for example, information indicating the position of the reference line with respect to the shape of the floor. For example, reference line data indicating the position of the reference line determined in the example shown in FIG. 12 is generated as construction support data. The position of the reference line is indicated, for example, as a relative position with respect to a reference position (for example, a corner, etc.) of the floor.

The format of the reference line data is not particularly limited, but may be, for example, a format that enables marking of the reference line at the construction site. For example, at a construction site, a computer with a display function such as a tablet or a personal computer can display information indicating the position of a reference line with respect to the floor. It is also possible to use an automatic marking device. In this case, as the reference line data, for example, data for an automatic marking device including the position of the reference point for marking and the position of the reference line with respect to the reference point may be generated. The automatic marking device can be configured such that the floor can be self-propelled, for example. In this case, the automatic marking device is configured to measure the relative position of the device with respect to the reference point, determine the current position, and draw a line on the floor at the position indicated by the reference line data. It should be noted that not only the automatic marking machine but also other devices such as a laser marking device can be used to reproduce the reference line indicating the reference data in the field. In this way, by generating the reference line data and reproducing the reference line with a computer or device at the construction site, the operator can visually check the reference line when performing the construction. As a result, more efficient and accurate construction can be realized.

Further, the reference line data may be in a format in which the operator can grasp the position of the reference line by using AR or VR technology at the construction site. Further, an application may be provided that visually outputs the position of the reference line to the operator by using the image showing the shape of the floor or other measurement result data acquired at the construction site and the reference line data. In this case, the position of the reference line is output to the operator by executing the application on the computer in the field. As a result, the worker can perform the construction while grasping the position of the reference line, and can surely perform the construction without actually providing the reference line.

The reference line is used, for example, at a construction site to determine the starting position of construction (installation) of a flooring material such as a tile or a sheet. Even if the flooring material is cut in advance along the determined cutting line, it is preferable to construct the flooring material from the center of the floor rather than constructing the flooring material from the edge of the floor. By constructing the flooring material from the center of the floor, the gaps at the ends can be evenly approached. As a result, the gap at the end becomes large in a part and is less likely to exceed the permissible range. Further, the larger the area of the floor on which the flooring material is applied at one time (for example, the larger the number of sheets or tiles to be applied), the more important the accuracy of the position of the reference line becomes.

The construction support data is not limited to the reference line data, and may include other data that can be used for laying the flooring material. For example, the construction support data may include edge processing data indicating the processing of the end portion of the flooring material in the above cutting line. The edge processing data is output to the operator by, for example, a computer at the construction site. The worker can grasp the processing method of the end portion of the flooring material. For example, information indicating end processing such as cutting the end of the floor material so that the cross section of the seam of a plurality of floor materials becomes V-shaped and welding the seam between the floor materials using a welding rod is provided to the site. Can be provided to workers. Thereby, the construction efficiency and the accuracy can be improved.

The construction support data may include, for example, information indicating the amount of adhesive that adheres the flooring material to the floor. The construction support data generation unit 22 can calculate the amount of the adhesive based on the area of the flooring material cut by the cutting line data. Further, the floor design data acquired by the floor design data acquisition unit 21 may include data indicating the adhesive. In this case, the amount of adhesive can be calculated based on the floor design data and the cutting line data. As a result, the adhesive prepared in advance is less likely to be wasted, and cost effectiveness is also obtained.

(Example of manufacturing cooperation data generation unit)
The manufacturing cooperation data generation unit 23 generates the manufacturing cooperation data used for manufacturing the flooring material to be cut at the cutting line indicated by the cutting line data. The manufacturing cooperation data is generated based on the cutting line data generated by the cutting line determination unit 14. The storage unit 16 may record the manufacturing cooperation data in the recording unit as cut data in association with the cutting line data or the floor identification information. By recording the manufacturing cooperation data in association with the floor specific information, the manufacturing cooperation data can be used at the time of manufacturing or construction of the floor material for the same floor. In addition, the manufacturing cooperation data can be used for the manufacturing of other floors or the calculation at the construction site. Thereby, the efficiency and accuracy of manufacturing or construction can be improved.

The manufacturing cooperation data generation unit 23 can be used as a flooring material to be cut by the cutting line data among the surplus lumber by referring to the surplus lumber data indicating the surplus lumber generated by cutting the flooring material, for example. Scraps may be extracted. Information indicating the extracted usable offcuts is included in the manufacturing cooperation data. The surplus scrap data may be recorded in advance in the recording unit 2, or may be recorded in an external system, for example. The surplus scrap data may include at least one such as model number, shape, thickness, material and appearance (color, pattern) of the surplus scrap. The surplus offcuts are, for example, offcuts produced by cutting performed in the past and whose use is undecided.

The manufacturing cooperation data generation unit 23 can, for example, extract scraps having the same thickness as the flooring thickness indicated by the flooring data acquired by the flooring data acquisition unit 13 from the surplus scraps data. In addition, the manufacturing cooperation data generation unit 23 can extract scraps having a size capable of realizing the shape of the flooring formed by cutting at the cutting line from the surplus scrap data. The manufacturing cooperation data generation unit 23 can include the information of the information indicating the extracted scraps in the manufacturing cooperation data as the information of the usable scraps. The manufacturing cooperation data is provided to the cutting machine 3 together with the cutting line data, for example. In this case, the cutting machine 3 cuts the offcuts indicated by the manufacturing cooperation data. This enables effective use of scraps.

The manufacturing cooperation data generation unit 23 may determine the printing area of the flooring material based on the cutting line indicated by the cutting line data, and may include the information indicating the determined printing area in the manufacturing cooperation data. The manufacturing cooperation data generation unit 23 may determine, for example, an area inside the cutting line as a print area. The manufacturing cooperation data including the information of the printing area is provided to the flooring production line including the printing process. This makes it possible to print only the part required for the flooring material. For example, it is possible to prevent printing on the portion of the flooring material that is not used after being cut. Thereby, the printing efficiency can be improved. The printing of the flooring material is not limited to a specific form, and examples thereof include forms such as inkjet, gravure printing, and rotary screen. This embodiment is suitably used for printing using an inkjet.

Further, the cutting line and the manufacturing cooperation data may be provided to the flooring production line. In this case, the production line can manufacture the flooring material of the required size, print it in the required area, and cut it based on the cutting line and the production cooperation data.

In addition, construction support data may be provided to the flooring production line. In this case, in the production line, for example, the construction support information indicated by the construction support data can be added to the floor material by printing, embossing, uneven shape processing, other processing, or the like. Alternatively, a microchip in which construction support data is recorded may be embedded in the floor material. Thereby, by reading out the data of the microchip with the computer at the construction site, it is possible to provide the worker with the construction support information such as the identification information of the floor material, the construction position of the floor material, or the work procedure. The construction support information can be provided, for example, by VR, AR using a computer, projection by a projection device, or the like. In addition to the form in which microchips are provided on the floor material, for example, barcodes and other symbols are printed on the surface of the floor material with ink emitted by ultraviolet rays, and these are read and converted by a reading device at the construction site, and the operator It is also possible to display in. Alternatively, instead of applying the adhesive at the construction site, the adhesive may be applied to the flooring material in advance and the release paper may be pasted on the flooring material. In this case, the construction support information may be displayed on the release paper.

(Example of cutting line generation using artificial intelligence (AI))
The cutting line determination unit 14 may determine at least a part of the cutting line by using the trained model. The trained model is, for example, an arithmetic model that inputs floor shape data and outputs a cutting line. In addition to the floor shape data, the trained model may input at least one of the floor material data and the floor design data, for example. The trained model is recorded in advance in, for example, the recording unit 2.

This allows at least a portion of the cutting line to be determined using AI. Further, the cutting line determination unit 14 can output the cutting line determined by the AI to the user and accept the selection or modification from the user. In addition to determining the cutting line, the trained model, that is, AI can be used to generate construction support data or manufacturing cooperation data.

In this case, the flooring precutting system 1a may include a learning unit 24 that generates a trained model. The learning unit 24 uses the data used by the cutting line determination unit 14 to determine the cutting line and the cutting line data of the flooring material actually cut based on the cutting line data as teacher data, for example, a neural network. A trained model may be generated by the deep learning used.

The actual cutting line data of the flooring material as the teacher data may be the actual cutting line measured at the construction site or the actual cutting line of the flooring material cut by the cutting machine 3. Further, the cutting lie based on the data input by the user as the information indicating the actual cutting line can be used as the teacher data. For example, as the teacher data, the cut data recorded in the recording unit 2 by the storage unit 16 may be used.

The learning process by the learning unit 24 includes, for example, preparation of a learning data set based on teacher data, preparation of a pre-learning model (learning program), and adjustment of parameters of the pre-learning model using the learning data set (learned model). Generation) is included. In the preparation of the training data set, for example, the teacher data is processed to generate the training data set. The teacher data on which the training data set is based can be, for example, the data used to determine the cutting line. For example, at least one of floor shape data, floor material data, and floor design data can be used as teacher data. In the preparation of the pre-training model, for example, pre-training parameters and hyperparameters are determined. In the trained model generation, the output result obtained by inputting the training data set to the pre-training model is collated with the teacher data, and the parameters of the pre-training model are adjusted. Here, as the teacher data to be collated with the output result, for example, the actual data of the cutting line indicated by the cut data is used. This adjustment process is repeatedly executed, and the trained parameters are determined so that an output result with a predetermined accuracy can be obtained.

The trained model is used, for example, as an inference program that inputs data on the target floor and flooring material and outputs a cutting line. For example, at least one of the floor shape data, the floor material data, and the floor design data can be input to the trained model, and a cutting line can be obtained as the output of the trained model.

For example, the cutting line determination unit 14 may present the cutting line determined using the trained model to the user. In this case, the learning unit 24 can use the learning unit 24 as the teacher data by accumulating the acceptance / rejection and correction results from the user. Further, the construction support data generation unit 22 and the manufacturing cooperation data generation unit 23 may also present the construction support data and the manufacturing cooperation data generated by using the learned model to the user. The learning unit 24 can use the acceptance / rejection and correction results from the user as teacher data. In this way, it is possible to make a system configuration in which a proposal is made regarding a cutting line and a construction method using AI, and the acceptance / rejection of the proposal and the correction result are input and feedback is given. By repeating the proposal and learning using the result, the quality of AI judgment is improved, and it becomes possible to propose a better cutting line and construction according to the characteristics of the construction site.
