[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and system for determining a floor material laying shape, and more particularly, to a floor material laying shape determining method and a floor material laying shape determining method for automatically cutting the floor material according to the shape of a room. Regarding the system.

2. Description of the Related Art Conventionally, in the construction of carpets and tiles, the necessary amount of materials is often determined in consideration of some margin with reference to the floor area of a room based on the drawings. Instead of actually allocating it on the drawing, determine the basic required amount from the floor area, determine the increase amount in anticipation of the allocation loss from the room shape based on many years of experience, and order the added amount.

If the material allocation reference position is wrong or the room shape size is different from the drawing, the material may be insufficient or a large amount of loss may occur. In addition, when constructing a cushion floor, etc., a construction method that roughly cuts the material according to the rough shape and pastes it side by side along the reference line provided near the center of the room, and the surplus near the wall is cut. May be taken. However, in recent years, consideration of the environment has been required for the treatment of waste material at the construction site, and this method in which a large amount of waste material is generated is not preferable.

In the case of a wood flooring material, etc., where dust is generated during cutting, indoor cutting work may not be permitted even in the present case. In such a case, it is necessary to mark the material after adjusting the dimensions at the site, take out the material to the outdoor work place, cut and process it, and carry in the completed work again and construct it. It spends a lot of effort and time.

In order to solve this, according to the "construction method of tile floor material" disclosed in Japanese Patent Laid-Open No. 7-247661, a tile floor material such as a stone tile or a ceramic tile having joints of a certain width can be simply and accurately The method of constructing is proposed.
In this construction method, a layout printing sheet, in which the construction positions of joints and tiles are printed in actual size, is spread on the floor surface to be constructed. Cut the printed sheet according to the shape of the floor edge,
Lay out the printed sheet with the assigned position numbers in the same state as after construction. The placed printed sheet is peeled off from the floor, and the tiles are cut into the same shape as the cut portion of the sheet. The obtained tiles are arranged through the joints according to the position number of the layout printing sheet, and the floor surface construction is completed.

[0006]

However, in the conventional floor material construction method, since the floor material shape is manually determined and cut according to the size of the room, the number of man-hours increases and the construction time becomes long. There was a problem. In addition, there is a problem that the burden required for waste material processing is large and that the dust produced by on-site processing adversely affects the environment.

The present invention solves the above-mentioned conventional problems and simplifies the processing of floor materials to shorten the construction time, reduces the burden required for waste material processing, and considers the environmental aspects, such as dust produced by on-site processing. The purpose is to eliminate. in addition,
Optimal allocation layout reduces material loss and costs.

[0008]

In order to solve the above-mentioned problems, the present invention relates to a method for determining the laid-in shape of a flooring material by inputting shape data obtained by measuring the shape of a room, and relating to the flooring material. Select a floor material from the database that stores the data,
Displays the state in which the selected floor material is spread, displays the room shape over the floor material, determines the floor material shape according to the room shape, and selects the floor material according to the determined floor material shape. The data to be cut is output.

With this construction, the construction time can be shortened, the burden of waste material processing can be reduced, and dust and the like can be eliminated. In addition, since optimal allocation can be examined in advance, material loss can be minimized.

FIG. 7: is a figure which shows the method of arranging a flooring material according to a center reference line.
FIG. 8: is a figure which shows the method of utilizing the flooring material of the edge part of a room.

The operation of the flooring material laying shape determination system according to the embodiment of the present invention configured as described above will be described. First, the basic function of the floor material laying shape determination system will be described with reference to FIG. Data relating to the floor material is stored in the database 2 in advance. In this database 2, floor material data can be freely registered. Attributes such as the type and pattern of the floor material can be specified and read from the database 2. The shape of the room to be constructed is measured by the automatic measuring device 1. As the automatic measuring device, a "room size measuring device" disclosed in Japanese Patent Laid-Open No. 2000-314626 may be used.

A floor material is selected on the terminal 3 and the state in which the selected floor material is spread is displayed. The figure of the room obtained by the measurement is displayed on the floor material. Rotate the direction of the room shape to match the direction of the floor material. Determine the shape of the flooring material according to the shape of the room. The processing device 4 searches for the positional relationship between the shape of the room and the floor material so that the usage amount of the floor material is minimized. The floor material is cut by the automatic cutting machine 5 according to the determined shape of the floor material. A known computer-controlled cutting machine may be used as the automatic cutting machine.

When the cutting position of the floor material is determined, a drawing showing a state in which the floor material is spread is printed. A unique identification code is attached to each floor material piece such as a tiled carpet. Even when the floor material is cut, the corresponding identification code is attached to the floor material. At the construction site, a floor material with an identification code corresponding to the drawing will be laid.

The operation procedure of the floor material cutting device will be described with reference to the flowchart of FIG. In step 1, the shape and dimensions of the room to be constructed are measured by the automatic measuring device 1. The measurement result is input to the processing device 4. In step 2, terminal 3
A floor material is selected from the database 2 using, and a state diagram in which the floor material is spread is displayed on the screen of the terminal 3. In step 3, the shape of the room is displayed on the floor covering. In step 4, align the room with the floor. In step 5, the floor plan of the room is translated so that the required amount of floor material is minimized. In step 6, the data on the cutting shape of the floor material is transferred to the automatic cutting machine 5. In step 7, the floor material is cut by the automatic cutting machine 5. In step 7, flooring is laid in the room.

With reference to FIG. 3, description will be given of a method for searching so that the floor material can be minimized. If the room edge does not match the shape of the floor material, the floor material needs to be cut to match the shape of the room edge. However, if the edge of the room matches the shape of the flooring material, it is not necessary to cut the flooring material, and thus the flooring material can be reduced. Therefore, the shape drawing 7 of the room is moved up and down and left and right by a fraction of the size of the floor material 6 to calculate the required number of floor materials. The cutting position of the floor piece is determined by finding the position where the number of floor materials is the smallest.

Another method for determining the arrangement of flooring materials will be described with reference to FIGS. As shown in FIG. 4, the wall surface of the room has some habits and is not necessarily a straight line. So even if you line up the materials along the line of the wall,
Actually, there is a gap between the wall and it. To eliminate this, the material must be cut along the line of the wall. Therefore, the floor material is placed on the assumption that all the materials in contact with the wall surface of the room may need to be processed.

In step 1, the room shape measured by a separate means such as an automatic measuring device is input to the floor material laying shape determination system. In the procedure 2, regarding the shape of the room acquired in the procedure 1, as shown in FIG. 5, the room shape diagram 7 is set so that the longest side of the room (in this example, side AD) is parallel to the X coordinate axis. Rotate. Furthermore, the room shape diagram 7 is translated so that all the points in the room are in the first quadrant of the XY coordinates, that is, all the coordinate values inside the room are X> 0, Y> 0. And display it on the terminal. This is to arrange the coordinate values so that they are all positive, and to simplify the arithmetic processing.

In step 3, a central cross line that serves as a room distribution reference line is defined and displayed. The central cruciform line is defined by taking the average value of the distances between two opposite sides. As shown in FIG. 6, a line that passes through the center of the line indicating the average of the upper side and the lower side of the room and is parallel to the X axis is the horizontal line of the central crosshair. The vertical line is obtained in the same way. As a result, when the material is placed, the reference is defined at the position where the cutting margin is most likely to be formed in the portion in contact with the wall surface.

In step 4, the floor material to be arranged is selected from the database, and as shown in FIG. 7, the floor material is arranged with the central crosshair as a reference, and the floor material is arranged on the figure showing the shape of the room. In step 5, if necessary, the operator finely adjusts the position of the central crosshair to determine the arrangement, and determines the position to cut the bare side.

In step 6, for the floor material that interferes with the wall surface (floor material that requires cutting), the cutting dimension and the shape of the end material are also calculated. Face to face 2 in step 7
Regarding the flooring material constituting the sides, one required shape and the other cut end material shape are compared. As shown in FIG. 8, if the end material shape includes a required shape, the end material is used as the material. The abcd of the floor material at the left end is a cut-off material, but the floor material at the right end can use a part of the abcd, and is set to be used.

As described above, in the embodiment of the present invention,
The floor material laying shape determination system measures the shape of the room, selects the floor material from the database related to the floor material, displays the state where the floor material is spread, and displays the room shape while displaying the room shape. Since the floor material shape is determined according to the shape and the floor material is cut in accordance with the determined floor material shape, the floor material construction time can be shortened.

[0025]

As is apparent from the above description, according to the present invention, a floor material laying shape determination system is provided with means for measuring and inputting the shape of a room, a database storing data on floor materials, and a floor. A means for selecting a material, a means for displaying a state in which the selected floor material is spread, a means for displaying the shape of the room overlaid on the floor material, and a means for determining the shape of the floor material according to the shape of the room And a structure for outputting the data for cutting the floor material according to the determined shape of the floor material, the floor material construction time can be shortened and the burden required for waste material processing can be reduced. The effect is that it can be reduced and dust and the like due to on-site processing can be eliminated.
