1. Explanation of Terms First, the terms used in this specification will be explained.

As shown in FIG. 6, the name of each part of the roof of the building includes large ridge (flat ridge), worship, gable, wall side, shed, eaves, valley, keraba, and eaves.

A "roofing material" 1 is a member that is attached to a roof having a substantially rectangular planar shape, and includes a slate roof, a galvalume steel plate (registered trademark), roof tiles, and the like. A slate roof is a material also called a thin roofing material, colonial (registered trademark), or color vest (registered trademark). Slate is made of cement and fibers and is widely used along with roof tiles. Galvalume steel plate is also called sheet metal in building materials. It is used in various places outside the house and is made of aluminum-zinc alloy plated steel plate, and most of what is called a metal roof is made of galvalume steel plate.

The "roof shape" of the roof of the building includes a hip roof shown in FIG. 1, a gable roof shown in FIG. 2, a shed roof shown in FIG. 3, a flat roof shown in FIG.

As shown in FIG. 2, a "strut" is a roof that protrudes further from the eaves of the main roof and has a slope in only one direction, that is, a roof that is lopsided.

A "roof plan" is a plan that shows the design of a building, especially the roof structure. It is a drawing that shows the roof, shape, finish, etc. when looking down on the building from directly above, like a plan view of the roof surface. It is a plan view of the outline of the roof, in which the shape, slope, materials, etc. of the roof are entered.

The "flow direction" is a direction along the inclination direction (slope direction) of the roof.

As shown in FIG. 5, the "gradient" of the roof includes 3, 4, 5, and 6 pitches. As shown in FIG. 5(a), the 3-inch slope refers to the state of being inclined 3-inch downward from 10-inch. "Sun" is a unit of length in shakukanho, and is defined as approximately 30.303 mm in Japan, which is 1/10 of shaku.

"Allocation" refers to arranging the allocation areas corresponding to the rectangular roofing materials 1 on the roof surface of the roof in order.

The "allocation area" corresponding to the roofing material 1 is not the size of the roofing material 1 itself, as shown by the hatched area in FIG. Rectangular area to be represented.

As shown in FIG. 16, the "working width d" is the dimension of the part hidden from the vertical dimension b of the roofing material 1 because the upper part of the roofing material 1 overlaps the lower part of the upper roofing material 1 and is hidden. Except for c, it refers to the vertical dimension of the roof material 1 exposed from the outside.

"Genuine" represents a roofing material 1 that can be allocated to the roofing material 1 to be allocated in the same member size as shipped.

A "cut item" represents a member that is cut from the original size of a member to be allocated and that is to be allocated.

2. Configuration of Roofing Material Allocation Device 10 The configuration of the roofing material allocation device 10 will be described with reference to the block diagram of FIG.

The roofing material allocation device 10 includes a personal computer (computer) control unit 12, the control unit 12 includes a display device 14 such as a liquid crystal display device, a printer 16, an input unit 18 such as a keyboard and a mouse, a scanner and a CAD device. A plan view input unit 20 consisting of, for example, is connected. The control unit 12 also has a roof shape storage unit 22 , a roof material storage unit 24 , a real data storage unit 26 , a cut data storage unit 28 and a storage unit 30 .

The roofing material storage unit 24 stores the types of roofing materials 1 and the vertical and horizontal dimensions of each roofing material 1 .

The genuine article data storage unit 26 stores data relating to the genuine article of the roofing material 1 .

The cut data storage unit 28 stores cut data of the roof material 1 .

As shown in FIGS. 1 to 4, the roof shape storage unit 22 stores various types of roof shapes, such as a hipped roof, a gabled roof, a shed roof, and a flat roof.

The storage unit 30 stores a roof material allocation program, a completed roof plan, and the like.

The roofing material allocating device 10 is connected to a cutting device 40 that cuts the real thing into cut pieces, and outputs cutting information for cutting the real thing to the cutting device 40 via the Internet, a communication device, and a storage medium.

3. Operating State of Roofing Material Allocation Device 10 Next, the details of the process for the contractor to allocate the roofing materials 1 to the roof of the building of a Japanese house using the roofing material allocation device 10 configured as described above will be described in order with reference to the flow chart of FIG. I will explain to The control unit 12 can realize the following functions by the roof material allocation program stored in the storage unit 30 . First, as shown in FIG. 10, the roof to which the roof material allocating device 10 allocates the roof material 1 is a hipped roof that is partially deformed and has an overhang.

(1) Step S1
In step S1, a plan view is input (see FIG. 11).

A plan view of a building is input from the plan view input unit 20 . At this time, if the building has two or more floors, the floor plan under each roof on each floor is input. At the time of this input, the actual size of the floor plan is also input. The input method is a scanner, CAD data, PDF data, or the like. The control unit 12 sets an absolute coordinate system, which is a two-dimensional xy orthogonal coordinate system, and its origin in consideration of the actual size of the input plan view. Here, the east-west direction is the x-axis direction, the north-south direction is the y-axis direction, the due east is the +x-axis direction, and the due north is the +y-axis direction.

(2) Step S2
In step S2, an exterior wall line is input (see FIG. 11).

The input unit 18 inputs the outer wall line of the floor plan of the building. This input is performed by moving the mouse along the outer wall in the plan view and tracing it with the cursor, or by inputting the numerical value representing the position of the outer wall in the absolute coordinate system and the actual dimension data of the outer wall line.

(3) Step S3
In step S3, the extension width is input (see FIG. 11).

A numerical value of the extension width, which is the distance from the outer wall line to the tip of the roof, is input through the input unit 18 . The width may be the same for all the north, south, east, and west exterior wall lines, or may be different for each of the north, south, east, and west exterior wall lines.

(4) Step S4
In step S4, border lines of north, south, east, and west are created (see FIGS. 11 and 12).

The control unit 12 creates a frame line indicating the outer frame of the roof plan at a position projected from the outer wall line by the protrusion width and the actual size data of the length of the frame line. This actual size data is calculated by the control unit 12 from the actual size data of the length of the outer wall line in the plan view and the numerical value of the width.

(5) Step S5
In step S5, a gradient such as the 3-inch gradient shown in FIG. 5 is input.

The slope of the roof is input through the input unit 18 . Note that the slope may be input after specifying the roof shape in step S6. In this case, instead of inputting the same slope for all roof surfaces, the slope may be input for each roof surface.

(6) Step S6
In step S6, the roof shape is specified.

The input unit 18 specifies the roof shape of the corresponding roof from a plurality of roof shapes stored in the roof shape storage unit 22, such as hipped roofs, gable roofs, and shed roofs as shown in FIGS. .

(7) Step S7
At step S7, a roof line is created.

The control unit 12 creates a roof line corresponding to the specified roof shape in the range surrounded by the frame lines.

(a) When the specified roof shape is a hipped roof (see Fig. 1)
A case of creating a roof line for a hipped roof whose specified roof shape is shown in FIG. 1 will be described.

First, an eaves attribute is added to each of the north, south, east, and west borders. It is assumed that each frame line (eaves) bends when it intersects.

Second, when adjacent frame lines (eaves) intersect at 90°, a corner ridge is created at a position, for example, 45° diagonal from one of the adjacent frame lines. Note that the angle of the roof line may not always be 45° depending on the slope of the adjacent roof surfaces, so in that case the angle of the roof line is adjusted according to the slope.

Thirdly, when adjacent frame lines (eaves) intersect at 270°, a trough is created at, for example, a 135° diagonal position from one of the adjacent frame lines. Note that the angle of the roof line may not always be 135° depending on the slope of the adjacent roof surface, so in that case the angle of the roof line is adjusted according to the slope.

Fourth, when one corner ridge and another corner ridge intersect, the one corner ridge and the other corner ridge end at that position.

Fifth, a flat ridge is created by connecting a point where two corner ridges intersect with a point where other two corner ridges intersect.

As described above, the roof line of the roof plan for the hipped roof can be created. Moreover, with this method, the roof line can be created not only for a perfect hipped roof as shown in FIG. 1, but also for a deformed hipped roof as shown in FIG.

(b) When the specified roof shape is a gable roof (see Fig. 2)
A case of creating a roof line in a gable roof whose specified roof shape is shown in FIG. 2 will be described.

First, the attribute of eaves and the attribute of "Keraba" are added to the north, south, east, and west borders.

Secondly, a flat ridge is created on the roof surface between the eaves facing each other.

As described above, the roof line of the roof plan for the gable roof can be created.

For example, the roof of the second floor of the building shown in FIG. 6 corresponds to the gable roof.

(c) When the specified roof shape is a shed roof (see Fig. 3)
A description will be given of a case where a roof line is created for a shed roof whose specified roof shape is shown in FIG.

First, with respect to the north, south, east, and west borders, the attribute of the eaves and the attribute of "Keraba" or the attribute of the wall are added.

Second, the flow direction is determined so that the position of the eaves is at the position of the lowest slope.

As described above, a shed roof does not have a roof line, and a roof plan can be created only by determining the flow direction.

For example, the eaves on the first floor of the building shown in FIG. 6 correspond to the shed roof.

Even if the specified roof shape is the flat roof shown in FIG. 4, the slope is only 0, and the rest is the same as the shed roof. In this case, the position of the eaves can be determined arbitrarily.

(8) Step S8
In step S8, a roof surface is created.

The control unit 12 creates a plurality of roof surface candidates surrounded by frame lines and roof lines.

The control unit 12 sets the flow direction of the roof surface candidate.

The control unit 12 inclines the roof surface candidate in the flow direction based on the slope, obtains the actual size data of the roof line, and creates the roof surface corresponding to the actual size data of the frame line and the actual size data of the roof line.

As a result, as shown in FIG. 13, the roof plan of the roof surfaces Y1 to Y8 to which the roof material 1 is not assigned is completed.

(9) Step S9
In step S9, the roof material 1 is specified.

The input unit 18 specifies a roofing material 1 (for example, a slate roof) to be allocated from a plurality of types of roofing materials 1 stored in the roofing material storage unit 24 . Information about the type of the roofing material 1 and the dimensions of the roofing material 1 specified from the roofing material storage unit 24 is input to the control unit 12 .

As shown in FIG. 15, the roofing material 1 has an individual coordinate system, which is a two-dimensional pq orthogonal coordinate system. The lower left end of the roofing material 1 is set to the origin (0, 0) of this individual coordinate system, the right end of the roofing material 1 is set to (a, 0), and the upper left end excluding the corners is set to ( 0,b) and the top right corner excluding the corners is set to (a,b). The information about the dimensions of the roofing material 1 includes the individual coordinate values of the corners of the roofing material (genuine) 1 in the individual coordinate system and the working width d. This individual coordinate system is independent of the absolute coordinate system. The identification of the roof material 1 is not limited to after step S8, and may be performed between steps S1 to S7.

(10) Step S10
In step S10, if there is a corner ridge on the roof as shown in FIG. 10, the contractor decides whether the corner ridge should be a ridge corner specification (FIG. 19) or a ridge wrap specification (FIG. 21). is selected by the input unit 18 .

(11) Step S11
In step S11, the allocation area corresponding to the roof material 1 is allocated to the roof surface (see FIGS. 13, 14 and 16).

(a) Allocation Rule of Allocation Area Corresponding to Roofing Material 1 on Roof Surface First, the allocation rule of the allocation area corresponding to the roofing material 1 on the roof surface will be described.

According to rule 1, when there are multiple roof surfaces Y1 to Y8 in the roof plan to which the roof material 1 is not assigned, the roof surface present in the clockwise direction from the easternmost roof surface Y1 to the roof surface Y8 Areas to be allocated corresponding to the roof material 1 are allocated in order (see FIGS. 10 and 13).

According to rule 2, the rectangular layout areas are arranged side by side in order from the left end (allocation start point P) on the eaves side of the roof surface to the right end toward the right so that they do not overlap. This arranging work means allocation. It should be noted that "from the left end (allocation start point P) to the right end toward the right" is an expression for easy explanation in FIG. 13, and actually means from one end of the eaves to the other end. is. Next, in the next stage, the allocation areas are allocated in order from the left end to the right end of the eaves. Further, the allocation areas are allocated in the same order for the next stage, and this process is repeated until the allocation areas are allocated up to the top level of the roof surface (see FIG. 14).

According to rule 3, the horizontal direction of the roof material 1 and the frame line of the roof surface are laid out in parallel (see FIG. 14).

Rule 4 allocates from the lower stage so that the vertical direction of the roof material 1 and the flow direction of the roof surface are parallel (see FIG. 14).

According to Rule 5, each position in the roof surface, the frame line, the flat ridge D1, the flat ridge D2, the corner ridge L, the corner ridge R1, and the corner ridge R2 are indicated by coordinate values in the absolute coordinate system (see FIG. 14). ).

Rule 6 relates to the laying position of the roofing material 1 . Regarding the real roof material 1, the number of the roof surface Y, the number of steps from the eaves (the bottom step is 1), and the assigned area counted from the left end of the roof surface (the portion that intersects the roof line) It is set with a number that indicates whether For example, the real object allocation area number of the real object allocation area that is located on the third stage of the roof surface Y1 and counted from the left end of the roof surface Y1 is "13-3". Regarding cutting items, indicate the number of the roof surface Y, L if it is on the left side of the roof surface or R if it is on the right side, the number of steps from the eaves, and the allocation area counted from the left end or right end. Set by number. For example, the cutting object allocation area number of the allocation area of the first cutting object counted from the left end on the second stage on the left side of the roof surface Y1 is "1L2-1".

Rule 7 stores an identification number indicating whether the roofing material 1 at each allocation position is genuine or cut. Then, the real thing and the cut thing are processed. This will be discussed later.

(b) Allocation method to the roof surface Y1 First, the control unit 12 starts from the left end (allocation start point P) of the position (first stage) closest to the eaves side of the roof surface Y1 on the east side toward the right end. Allocate allocation areas in order. As for the determination of the left end, if there is an allocation area on the line of the corner ridge L on the left side of the roof surface, the left end is determined. Also, the right end portion is judged as the right end portion if there is an allocation area on the line of the corner ridge R1 and the corner ridge R2 on the right side of the roof surface (see FIG. 14). The number of layout areas arranged in a row at the position of the frame line is determined by dividing the actual size data f of the horizontal dimension of the frame line by the horizontal dimension g of the layout area (=f/g). Fractions of the divided number (=f/g) are treated as cuts, which will be described later.

Secondly, when the allocation of the first stage is completed, the control unit 12 sequentially allocates the allocation areas from the left end to the right end of the second stage. At this time, the layout areas are arranged in a zigzag pattern by shifting the layout position of the rectangular layout area in the first row by half the size of the layout area in the horizontal direction (see FIGS. 14 and 16). In other types of roofing materials 1 (for example, roof tiles), the allocation areas may be allocated in a straight manner.

The control unit 12 similarly performs allocation up to the uppermost stage of the roof surface Y1. This judgment assumes that when the allocation position of the allocation area reaches the position of flat roof D1, allocation is made up to the top level of the roof surface (see FIG. 14). Allocation of the roof material 1 to the roof surface Y1 on the east side shown in FIG. 14 is now completed. It should be noted that, during this process, the processing of the genuine article and cut article (steps S21 to S42), which will be described later, is executed.

Next, the roof surface Y2 is allocated, and finally the roof material 1 is allocated to all the roof surfaces Y1 to Y8 as shown in FIG. 18 to complete the roof plan.
11. In step S11, a roof plan with allotted roof materials 1 is output (see FIG. 18).

The control unit 12 causes the display device 14 to display the roof plan to which the roof materials 1 shown in FIG. 18 are allocated. Further, the control unit 12 stores the roof plan to which the roof materials 1 are allocated in the storage unit 30 .

If there are other roofs on the same floor of the building or on other floors, a roof plan for each roof is created in the same manner.

(12) Steps S12 to S15 (Equal splitting of sugi)
When the roof plan is displayed on the display device 14 as described above, when the working widths are not evenly assigned to the sills on the south side of the roof, the viewpoint of improving the design and simplification of the assignment work. From the point of view of the above, there are cases where it is desired to make the working width of the grip even. Therefore, the roof material allocating device 10 of this embodiment has a function of evenly dividing the slats. This function will be described based on steps S12 to S15 in the flow chart of FIG.

In step S12, the input unit 18 is used to select whether or not the roofing materials 1 are to be evenly laid out. If it is selected to allocate evenly, the process proceeds to step S13 (in the case of y). The user selects not to execute this function and proceeds to step S15 (in the case of n).

In step S13, in order to divide the siding evenly, as shown in FIG. and a second specifying line T2.

The specific point G is given at the position of the eaves of the roof surface Y2 where the sill of the roof plan begins to protrude from the frame line, and at the left end or right end (the left end in FIG. 17) of the sill.

The first specific line T1 is a line parallel to the frame line (eaves) and specifies the position of the uppermost step in the width direction of the bridge.

The second identification line T2 identifies along the direction of flow from the position of the eaves of the roof surface Y2 where the overhangs start to protrude to the position of the eaves of the overhangs.

In step S14, the control unit 12 sets the real object allocation area and the cut object allocation area so that the working widths d are all the same with respect to the specified hanging range. This setting method is the same as the allocation method of the roof surface Y2 described in step S11. As much as possible, even allocation is performed with the same working width as that of the allocation area of roof surface Y2. The working width d is set so that even allocation can be performed by .

In step S15, when the roofing materials 1 are assigned to this sling, the shape and number of cut pieces may change, so the assignment of the roofing materials 1 performed in step S11 is performed again. Then, the process proceeds to step S16.

(13) Step S16
In step S16, the control unit 12 generates a roof plan in which the working width d of the roof material 1 is evenly assigned to the slings, or a roof sloping plan when the evenly splitting of the roof material is not executed, and a cut piece to be described later. The data is displayed on the display device 14 , printed out by the printer 16 , and stored in the storage unit 30 .

Also, the control unit 12 outputs the cut data to the cutting device 40 via the Internet line or a storage medium.

4. Allocation adjustment function for flat ridges and wall joints In the above allocation, special allocation is executed for allocations near flat ridges. The flat ridge of the roof must be covered with a metal ridge cover with a coping attached. At this time, in order to prevent the end of the roof covering from straddling between the roof material 1 on the highest level and the roof material 1 one level below, the vertical dimension ( It is desirable that the width in the machine direction) be about 150 mm to 250 mm (hereinafter referred to as "required dimension h"). As for the roof material 1 on the uppermost level that is in contact with the flat ridge, no other roof material 1 overlaps on it, so there is no working width, and the vertical dimension of the roof material 1 (cutting) does not exist. , is the vertical dimension of the allocation area.

However, when the roofing materials 1 are laid out in order from the lowest level with the eaves, the vertical dimension of the allocation area of the roofing materials 1 on the top level may be smaller than the required dimension h.

Therefore, as shown in FIG. 27, the control unit 12 sets the vertical dimension to the required dimension h It has an allocation adjustment function that sets it to be In addition, the control unit 12 reduces the vertical dimension of the lowermost allocation area by the length of the vertical dimension of the uppermost allocation area. Depending on the shape of the roof, it is not necessary to adjust only the vertical dimension of the allocation area one step below, but if necessary, the vertical dimension of the allocation area of multiple stages including the vertical dimension of the allocation area one step below. You may adjust so that a dimension may become small little by little.

In addition, as shown in FIG. 29, since it is necessary to apply ridge wraps to flat roofs D2 other than the top flat roof D1, that is, to flat roofs D2 other than the top floor, the allocation area of the roof material 1 in contact with the flat roof D2 is Similarly, the required dimension h is secured, and the vertical dimension of the allocated area one step below is made smaller by that amount. Depending on the shape of the roof, it is not necessary to adjust only the vertical dimension of the allocation area one step below, but if necessary, the vertical dimension of the allocation area of multiple stages including the vertical dimension of the allocation area one step below. You may adjust so that a dimension may become small little by little.

In the roof of FIG. 10, there is no roof surface in contact with the wall. Similarly, the necessary dimension h is ensured for the vertical dimension of the allocation area of the roof material 1 on the uppermost stage. This is because it is necessary to attach a rain flashing to the roof material 1 on the uppermost stage that is in contact with the wall. Then, the vertical dimension of the allocation area one step below is reduced accordingly. Depending on the shape of the roof, it is not necessary to adjust only the vertical dimension of the allocation area one step below, but if necessary, the vertical dimension of the allocation area of multiple stages including the vertical dimension of the allocation area one step below. You may adjust so that a dimension may become small little by little. In the description based on FIGS. 27 to 29, to make smaller means to make the vertical dimension of the allocated area uniform, or to adjust it to a predetermined dimension.

5. Processing of Genuine Objects and Cut Objects Next, the processing of genuine objects and cut objects in the layout of the roofing materials 1 will be described with reference to the flow chart of FIG.

In step S21, in the allocation area allocated to the roof surface Y1, a portion of the roof material 1 in which the original can be used as it is is set as the "genuine allocation area". The real allocation area number explained in Rule 6 is given. In addition, a real object allocation area number is assigned to the real object allocated to each real object allocation area. For example, the allocation area filled with hatching lines in FIG. 16 can be set as the genuine allocation area. At this time, the positions of the coordinate points of the corners of each real object layout area are calculated as the layout positions. This calculation is performed based on the coordinate position of each point on the roof surface Y1 in the absolute coordinate system.

In step S22, areas other than the real object allocation area are set as "cutting object allocation areas", and the cutting object allocation area numbers described in Rule 6 are given to each of the cutting object allocation areas. The coordinate values of the absolute coordinate system of the roof lines forming the upper, lower, left, and right sides of the roof surface Y1 are stored, and these roof lines intersect in the cut object allocation area.

In step S23, first, a cut-out allocation area for allocating cut-outs is set. This setting may be made from the allocation start point P or from an arbitrary point. In this description, the allocation start point P is set as the cut object allocation start point, and when the allocation of the cut objects is started in order from this cut object allocation start point in the upward direction and all the cut objects are allocated in the upward direction, the next allocation is performed. The order of allocation to the cut object allocation area on the right side of the starting point P is set. Note that this order may be determined arbitrarily.

In step S24, the cutout allocation area number corresponding to the set cutout allocation area and the shape and size of the cutout (hereinafter collectively referred to as "cutout data") are obtained. The shape of the cut is specified by the individual coordinate values of each corner of the cut, and the dimension means the shortest distance between the individual coordinate values of adjacent corners.

In step S25, the cut item identification number and the cut item data corresponding to this cut item are retrieved from the cut item data storage unit 28 and called out. The "cutting identification number" is a number different from the cutout allocation area number, and is an identifier for distinguishing the cutout from other cutouts before allocating the cutout to the cutout allocation area. be.

This step is omitted because there is no cutting data at the first position of the first roof surface Y1. However, since this cut object data exists in the allocation of the cut object in the second cut object allocation area on the roof surface Y1 and the allocation on the roof surface from the next time onward, retrieval is performed from among the cut object data.

As the "cutting allocation conditions" for this search, the first condition is the cutting object having the horizontal and vertical dimensions larger than the cutting allocation area, and the second condition is the cutting object A search is made for the smallest difference between the horizontal or vertical dimension of the allocation area and the horizontal or vertical dimension of the cut object.

If it is determined in step S26 that there is no cut object having horizontal and vertical dimensions larger than the horizontal and vertical dimensions of the cut object allocation area, which is the first condition of the cut object allocation conditions, it is determined that there is no corresponding cut object. and proceed to step S36 (in the case of n). Also, if there is a cut object that meets the first condition, the process proceeds to step S27 (in the case of y).

In step S27, it is determined whether or not the size of the corresponding cut object can be allocated to the cut object allocation area. ), otherwise the process proceeds to step S30 (in the case of n). This determination is made by comparing the vertical and horizontal dimensions of the stored cut object with the vertical and horizontal dimensions of the cut object allocation area.

In step S28, since the cut object can be allocated in its original size, the cut object is allocated to the set cut object allocation area, the cut object allocation area number is given to the cut object data, and the The position of the coordinate point of the corner of the object layout area is calculated as the layout position.

In step S29, the cut item identification number of the allocated cut item is deleted from the cut item data storage unit 28, and the process proceeds to step S41.

In step S30, since it is determined in step S27 that the cut object cannot be laid out in its size, the cut object is cut in accordance with the cut object corresponding layout area, and the process proceeds to step S31.

In step S31, the cut object is allocated to the set cut object allocation area. Then, a cut object allocation area number is assigned to the cut object allocated to the cut object allocation area, and the position of the coordinate point of the corner of the cut object allocation area is calculated as the allocation position.

In step S32, the cut item identification number of the allocated cut item is deleted from the cut item data storage unit 28, and the process proceeds to step S33.

In step S33, it is determined whether or not the part remaining after cutting the object can be registered as a new object to be cut. An object identification number is assigned, and stored in the cut object data storage unit 28 together with the cut object data, and the process proceeds to step S41. If the remaining portion cannot be registered as a cut item (in the case of n), the data of the remaining portion is discarded in step S35, and the process proceeds to step S41. Here, as a condition for judging whether or not the remaining part can be registered as a cut object, for example, a state in which all parts other than the genuine object and the part having the inclined surface of the cut object can be used. .

In step S36, since it is determined in step S26 that there is no corresponding cut object, a new genuine object is cut corresponding to the set cut object allocation area.

In step S37, the cut object is allocated to the cut object allocation area. In this case, a cut object layout area number is assigned to a newly created cut object, and the position of the coordinate point of the corner of the cut object layout area is calculated as the layout position.

In step S38, it is determined whether or not the remaining portion of the cut genuine article can be registered as a cut article. This determination method is the same as the cut object determination condition in step S33. Then, if the object satisfies this cut object determination condition (in the case of y), a cut object identification number is assigned to the remaining portion and registered in the cut object data storage unit 28 in step S39. In this case, a newly created cut item identification number and cut item data are registered. Then, the process proceeds to step S41. On the other hand, if the cut object judgment condition is not satisfied (in the case of n), the remaining portion is discarded in step S40, and the process proceeds to step S41.

In step S41, since the cut object has been allocated to one cut object allocation area, it is determined whether or not to proceed to the next cut object allocation area. If the cut objects have been allocated to all the cut object allocation areas, the process proceeds to step S42 (in the case of y), otherwise returns to step S24 (in the case of n).

In step S42, since the real object and the cut object have been assigned to all the real object allocation areas and the cut object allocation areas, the allocation of the roof surface is finished, and the real object identification number and its allocation position assigned to each allocation area are determined. Also, the cut item identification number and its allocation position are stored.

In step S43, this allocation process is sequentially performed clockwise from the roof surface Y1 on the easternmost side of the roof plan. Returning to S21, when there is no next roof surface and allocation of all the roof surfaces Y1 to Y8 is completed (in the case of n), the allocation process ends. At this time, the cut objects are handled on a certain roof surface, and the cut objects not used on that roof surface are used for allocation on the next roof surface. Then, the number of roofing materials 1 used for the allocation of all roof surfaces (the total number of genuine materials and the number of genuine materials used for cutting) is stored.

Furthermore, the control unit 12 similarly performs allocation processing of the real roofing materials 1 and the cut pieces for roofs on the same floor of the building or on other floors, and manages the cut pieces used for each roof. I do.

6. Calculation of cut data A method for calculating the cut data in step S24 will be described.

Since the roof line and the real roof material 1 to be allocated intersect in the cut object allocation area, the individual coordinate values of the respective corners of the cut object are obtained from this intersection position. The method is as follows.

First, as shown in FIG. 15, the lower left end of the roofing material 1 (genuine) is aligned with the lower right end of the adjacent real allocation area, and its position is set to the origin (0, 0) of the individual coordinate system. set to Since the coordinate values of the absolute coordinate system are known in advance at the time of allocation, the lower right end of the adjacent real thing allocation area has the origin (0, 0) of the individual coordinate system of the roof material 1 and the coordinate values of the absolute coordinate system. Determines the correspondence between

Secondly, the absolute coordinate values of the absolute coordinate system are obtained for the roof line. Therefore, the absolute coordinate values of the absolute coordinate system forming the roof line are converted into the individual coordinate values of the individual coordinate system based on the correspondence relationship.

Thirdly, the individual coordinate values of the roof line converted into the individual coordinate system become the individual coordinate values of the respective corners of the cut object when the real object is cut to produce the cut object. Note that the size of the cut object and the size of the cut object allocation area are not the same. becomes.

The cut data is calculated as described above. In the case where the roof line is arranged in the corner ridge, verge, or valley, the control unit 12 obtains the cut data as follows. .

(1) Cut Items Placed in Corner Ridges Cut items placed in corner ridges will be described with reference to FIGS. 19 to 22. FIG. As for the corner ridge, there are ridge corner specifications and ridge wrap specifications. Therefore, the specification of the corner ridge is determined in step S10. Note that the ridge corner specification in this embodiment includes not only a specification using an insert ridge, but also a specification in which cut objects are butted against each other so that they are in contact with each other, and the butted portion is shown as it is.

When the ridge corner specification is selected, as shown in FIG. 19, a cut piece obtained by obliquely cutting the original piece is placed in the corner ridge as it is. is obtained from the individual coordinate values of the line where the genuine article and the corner ridge intersect.

Then, the control unit 12 stores the determined individual coordinate values of the corners of the cut object together with the cut object allocation region number as cut object data in the cut object data storage unit 28 . Further, the control unit 12 converts the individual coordinate values of the corners of the cut object into the shape and size of the cut object, and outputs them together with the cut object allocation area number on the output screen as shown in FIG. In the output screen shown in FIG. 20, the upper screen displays the cutout allocation area number to which the cutout is allocated, and the lower screen displays the shape and size of the cutout corresponding to the cutout allocation area number. be done. It should be noted that the screen of FIG. 20 is an example, and two pieces are cut out from one genuine article.

When the ridge wrap specification is selected, it is necessary not only to cut the real thing diagonally to form a cut piece like the ridge corner specification, but also to cut off the corner of the bottom end of the cut piece and cut the corners. There is When the control unit 12 cuts corners, the individual coordinate value of the lower edge of the line where the cut object and the corner ridge contact each other is used as a reference point to cut off, and the individual coordinate value of the lower end of the cut object is obtained. Coordinate values for determining the shape and size of the corner cut are set in advance with reference to the reference point.

Then, the control unit 12 stores the individual coordinate values of the corners of the corner cut object as cut object data in the cut object data storage unit 28 together with the cut object allocation area number. Further, the control unit 12 converts the individual coordinate values of the corners of the cut object into the shape and size of the cut object, and outputs them together with the cut object allocation region number on the output screen as shown in FIG. In the output screen shown in FIG. 22, the upper screen displays the cut-out allocation area number, and the lower screen displays the shape and size of each cut-out. It should be noted that the screen of FIG. 22 is an example, and two pieces are cut out from one genuine article.

(2) Cut Objects Arranged in Lambs Next, bridles will be described with reference to FIGS. 2, 23 and 24. FIG. The roof in FIG. 10 does not have a "keraba", but it may have a "keraba" as shown in FIG.

At this time, as shown in FIG. 23, the control unit 12 first obtains the shape and size of the cut object from the individual coordinate values of the line where the true object and the bristle intersect.

Next, as shown in FIG. 23, since it is necessary to provide a shoulder to the cut object when it is arranged in a bridle, the corners of the upper end of the cut object are cut off. When the control unit 12 provides the cut off, the individual coordinate value of the upper end corner of the line where the cut object and the bristle meet is used as a reference point to cut off, and the individual coordinate value of the cut off upper end of the cut object is obtained. Coordinate values for determining the shape and size of the cutoff are set in advance with reference to the reference point.

Then, the control unit 12 stores the individual coordinate values of the corners of the cut object provided with the cut off as cut object data in the cut object data storage unit 28 together with the cut object allocation area number. The control unit 12 also converts the individual coordinate values of the corners of the cut object into the shape and size of the cut object, and outputs them together with the cut object allocation area number on the output screen as shown in FIG. In the output screen shown in FIG. 24, the upper screen displays the area number of the cutout allocation area, and the lower screen displays the shape and size of the cutout. It should be noted that the screen of FIG. 24 is an example, and two pieces are cut out from one genuine article.

(3) Cut objects arranged in valleys Next, cut objects arranged in valleys will be described with reference to FIGS. 25 and 26 .

As shown in FIG. 25, first, the control unit 12 obtains the shape and size of the cut object from the individual coordinate values of the line where the true object and the trough intersect.

Next, as shown in FIG. 25, since it is necessary to provide a shoulder on the cut object that is in contact with the trough, the upper corner of the cut object is cut off. When the control unit 12 provides the shoulder, the individual coordinate value of the upper edge of the line where the cut object and the trough meet is used as a reference point to cut off, and the individual coordinate value of the upper end of the cut object is obtained. Coordinate values for determining the shape and size of the cutoff are set in advance with reference to the reference point.

Then, the control unit 12 stores the individual coordinate values of the corners of the cut object forming the shoulder as cut object data in the cut object data storage unit 28 together with the cut object allocation area number. Further, the control unit 12 converts the individual coordinate values of the corners of the cut object into the shape and size of the cut object, and outputs them together with the cut object allocation area number on the output screen as shown in FIG. In the output screen shown in FIG. 26, the upper screen displays the cut-out allocation area number, and the lower screen displays the shape and size of the cut-out. It should be noted that the screen of FIG. 26 is an example, and one cut item is cut out from one genuine item.

7. Calculation of waste material information The control unit 12 is a waste material information calculation means, and obtains waste material information discharged from the roofing material 1 used for the roof. We will explain how to obtain it.

First, the area of each cut object is obtained from each cut object data (shape and size of cut object) assigned to all roof surfaces.

Next, the areas of all the cut objects are totaled to determine the total area of the cut objects.

Next, the total real area of the real objects used to create all the cut objects is obtained. Since the vertical and horizontal dimensions of the genuine article are known in advance, the area of one genuine article is obtained from the dimensions, and the total area of the genuine article is obtained by integrating the number of used genuine articles.

Next, the waste material area is obtained by subtracting the total area of the cut material from the total area of the real material.

Also, the unit weight per unit area of the roof material 1 is obtained or stored in advance.

Next, the total area of the cut pieces is multiplied by the unit weight to obtain the total weight of the cut pieces.

Next, the total waste material weight is obtained by multiplying the waste material area by the unit weight.

Next, the cutting device 40, which outputs cut data, obtains the number of times each cut is cut. Normally, the number of sides of the cut object excluding the sides of the real object is the number of cuts.

Next, the number of cuts for each piece is totaled to obtain the total cut total.

The total cut area, the waste area, the total weight of the cut, the total weight of the waste, and the total number of times of cutting obtained by the control unit 12 as described above are displayed on the display device 14 as waste material information, printed on the printer 16, and stored. Store in unit 30 .

As a result, the trader can obtain the waste material information generated from the roofing material 1 used on this roof.

8. Output Information to Cutting Device 40 As the cut data to be output to the cutting device 40, the shape, size and cut allocation area number of each cut are output. The cutting device 40 cuts the real object based on the cut object data, and prints the cut object allocation area number on the cut object.

When the cutting device 40 prints the cutout allocation area number on the cutout, it can be printed at any position when printing on the back side of the cutout. However, in the case of printing on the surface of the cut article, printing is performed on the portion hidden by a different cut article covering the upper stage of the cut article. At this time, since the working width d of the cut piece is known in advance, the individual coordinate values forming the printable range are set so as to print on the portion outside the range of the working width d (portion other than the exposed portion). The control unit 12 outputs.

9. Effect According to the present embodiment, the roofing material 1 can be evenly allocated to the slats protruding from the roof surface, and the appearance becomes beautiful.

In addition, in the corner ridge, simply by selecting the ridge corner specification and the ridge wrap specification, the corresponding cut data can be output.

In addition, it is possible to automatically output cut-piece data in which shoulders are cut off with respect to briskets and valleys.

In addition, the required dimension h can be ensured for the roofing material 1 in contact with the flat ridge and the wall joint portion so that the ridge cover and the rain flashing can be installed.

Also, waste material information can be obtained from the cut data.
