[0017]

Embodiments of the present invention will be specifically described below with reference to the drawings. The field material W to which the present embodiment is applied is generally made of heartwood from which the bark of a pine log has been stripped. For example, as shown in FIG. Is used as a beam to support the load on the roof and ceiling while pulling the outer side of
And assembled.

As shown in FIG. 1, a pre-cutting system for wild material according to the present embodiment for pre-cutting such a wild material W is a CAD 2 as a data holding means provided in a computer 1 such as a personal computer. , Calculation means 3, processing data generation means 4, measurement means 5, CRT 6 as display means, and processing means 7. The CAD (Computer Aided Design) 2 is composed of CAD software which operates on the computer 1, and the arithmetic means 3 and the processing data generating means 4 are arithmetic software which can operate on the computer 1 to perform a predetermined arithmetic operation. Is preferred.

The CAD 2 has assembling data D1 of the structural materials of the entire building except for the wild material W, and can display an assembling drawing based on the assembling data D1 on the CRT 6. The CAD 2 used here is for general-purpose design, and may be one that can display an assembly drawing in two dimensions or one that can be displayed in three dimensions.

The calculating means 3 calculates a position of the wild material W related to other structural materials when the range in which the wild material W is to be assembled in the building is specified from the assembly data D1 by the CAD 2. . The designation of the range in which the wild material W is to be assembled is specified on the CRT 6 by assembling a structural drawing excluding the wild material W and viewed from above the building (planar assembly drawing). This is performed by inputting the height of the end portion and the material (material height) to the desired position (input of the range information IN) while displaying. After the input, when the display is switched to the display of the assembly drawing viewed from the side, two upper and lower straight lines representing the height of the end and the material (material height) are automatically displayed. Note that the upper and lower two straight lines can be input from a mouse or a keyboard (both not shown) connected to the computer 1.

A schematic description of such range designation will be given below. As shown in FIG. 2, in an assembly drawing (as viewed from the side of a building) displayed on a CRT 6 based on assembly data D1 from CAD2. When assembling the field material W between the structural materials W1 and W2, two straight lines L1 and L2 connecting these are input and displayed as range information IN. That is, the approximate position where the wild material W is to be assembled is designated by the two straight lines L1 and L2, and is treated as a temporary material consisting of such straight lines.

Thus, since the wild material W having a unique bending degree can be uniformly placed as a temporary material consisting of a straight line, the input to the CAD 2 becomes easy. Further, by displaying the temporary material composed of straight lines in this way, the position of the wild material W related to other structural materials can be easily understood. For example, in FIG. 2, when the origin of the position of the field material W with respect to other structural materials is the horizontal position of the structural material W1, the positions of 0 and c relating to the structural materials W1 and W2 and the structure The positions of a and b associated with the materials W3 and W4 are transmitted to the measuring means 5 as position information D2.

The transmission of the position information D2 may be performed on-line between the computer 1 and the measuring means 5, or may be performed by an output means (such as a printer) which is electrically connected to the computer 1 once. The measurement by the measuring means 5 may be performed according to the contents.

The measuring means 5 determines the wild material W at each position (0, a, b, c) based on the position information D from the calculating means 3.
Is to measure the external dimensions of the device, as shown in FIG.
Black ink is applied to positions 0, a, and b of the wild material W to be actually processed, and the outer dimensions of the position (the position in the vertical direction in the figure and the horizontal reference line x to the upper end in the figure) Is measured. Here, the measuring means 5 includes not only those measured by a general-purpose measuring device such as a digitizer, but also those measured and blackened by an operator manually. Although the left end (position of 0) of the field material W is cut for convenience, the drawing also shows a configuration in which the left end is also precut, and blacking is required for the position of 0 as well. Become.

The external dimensions (the vertical dimensions t1 to t4 and the dimensions t1 'to t4' from the horizontal reference line x to the upper end) data D3 at each position are transmitted to the processing data generating means 4. Such transmission may be configured such that the worker may input the external dimension data D3 to the computer 1 or may be performed directly online from the measuring means 5.

The processing data generating means 4 outputs the outer dimensions (t1-t4 and t1'-t) of the wild material W obtained by the measuring means 5.
4 ′) and assembly data (positions and cross-sectional dimensions of each structural material) of the structural materials (W1 to W4) related to the wild material W.
The processing shape and the processing size for the wild material W are determined.

That is, two straight lines L displayed as temporary materials
The positions of 0, a, b, and c in 1 and L2 are corrected in accordance with the actual outer dimensions of the wild material W, and as shown in FIG. 3, the corrected state (the straight lines L1 and L2 correspond to the respective positions). Are assembled into a plurality of straight lines.)
6 is displayed. In this way, by displaying the corrected assembly drawing, the relationship between the wild material W and the structural material other than the wild material W can be determined, and the processed shape and the processed size can be set to C.
Can be determined on AD2. The processing shape and processing dimensions determined here are transmitted to the processing means 7 as processing data D4.

The processing shapes of the wild material W include, for example, a helmet ant (male or female), a large insert ant (male or female), a large insert (male), a two-stage tenon (male), a draw bolt hole, and an oblique chipping. There may be a hole, a side bolt hole, a crossover jaw, a tenon, a tenon, a dowel hole, etc., and the most appropriate one is selected according to the relationship between the wild material W and other structural materials.

In the above description, the processing shape and the processing size of the wild material W are determined so as to be adapted to a structural material other than the wild material W. The processing shape and processing dimensions of the structural material other than the material W may be determined. For example, in FIG. 3, the lower end face W of the structural material W4
When 4a is located at the position of W4a ', processing data for cutting the tip of the structural material is created so as to be at the position of W4a.

The external dimension data D3 may be as follows. That is, the coordinates of the upper end and the lower end at each position may be used as the outer dimension data D3, and may be the dimensions from the horizontal reference line x to the lower end instead of the dimensions from the horizontal reference line x to the upper end. Even in this case, the processed data generating means 4 can perform the same display as described above.

The processing means 7 is for processing the wild material W measured by the measuring means 5 on the basis of the processing shape and the processing dimensions (processing data D4) determined by the processing data generating means 4, and is shown in FIG. As shown in FIG. 7, a processing table 8 on which the wild material W is to be placed, and a wild material W on the processing table 8.

c by the air cylinder 9a.
And a sliding surface 9b that can abut against the other side surface,
The field material W can be held at a desired position by sliding on the processing table 8. Here, the holding position of the wild material W is set to be different from the positions related to other structural materials in the wild material W calculated by the calculating means 3 (positions La and Lb sanitized by the measuring means 5), Interference between the router 10 and the clamping means 9 during processing is prevented.

The air cylinder 9a, sliding surface 9b
The fixing surface 9c is disposed on a plate 9f slidable in the width direction of the processing table 8, and the plate 9f
Is screwed into the tip of an adjusting screw 9e that rotates when the handle 9d is turned, and the plate 9 is fixed by the handle 9d.
It is configured so that f can be positioned. Further, the clamping means 9 is slidable in the longitudinal direction of the processing table 8 along a rail 8a formed on the processing table 8, and is configured to be able to clamp the wild material W at a desired position. ing.

The router 10 is mounted on a base 11 and is controlled so as to move in the vertical and horizontal directions with respect to the field material W on the processing table 8, and is driven by a motor 11 a disposed on the base 11. The base 11 is the processing table 8
(In FIG. 5, in FIG. 5)
The state where the base 11 has reached the left end of the processing table 8 is indicated by a two-dot chain line. ). Here, the movement of the router 10 and the base 1
The control for the sliding of No. 1 is numerical control (NC) based on the processing data D4 (processing shape and processing size) determined by the processing data generating means 4, and is controlled by a perforated tape.
Alternatively, it may be either by program input.

The base 11 is provided with a beam ruler capable of emitting a laser beam to a desired position on the processing table 8. For example, as shown in FIG. Lines c1 and c2 are displayed on the upper side, and the line c1 corresponds to the horizontal reference line x.
When the intersection point between c and c2 is set as the origin, the positioning when placing the wild material W on the processing table 8 can be facilitated.

In order to process the wild material W by the processing means 7, the wild material W is placed on the processing table 8 while being positioned by the light ruler, and is then combined with other structural materials in the wild material W. A portion other than the relevant position is fixed by the clamp means 9. At this time, after each of the clamping means 9 is slid to a position for holding the wild material W, the handle 9d is rotated until the state where the wild material W can be held at that position, and the plate 9f is moved. By driving the air cylinder 9a, the field material W is held between the fixed surface 9c and the sliding surface 9d.

Thereafter, based on the processing data D4, the router 1
0 is operated in the vertical and horizontal directions to process the wild material W. The base 11 is provided with a circular saw blade in addition to the router 10, and can also perform cutting of a wooden material W at a tip.

Subsequently, the processing data D obtained in the processing data generation step S3
Based on 4, the processing is performed on the wild material W by the processing means 7 (processing step S4), and a series of precuts on the wild material W is completed.

According to the precut method and precut system for the wild material W, the assembly data D of the CAD 2
