[0011]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, a wood processing apparatus according to a first embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram showing the configuration of the wood processing apparatus of the first embodiment. This wood processing device includes a processing data creation device 40 that creates data for wood processing, a processing machine 54 that processes wood, a processing control device 52 that controls the processing machine 54, and a reversal that inverts wood in a desired direction. The apparatus 58 includes a reversing control device 56 that controls the reversing device 58, a printing device 60, and conveying rollers 80 and 84, and the processing control device 52, the reversing control device 56, and the printing device 60 are controlled by a single control device 50. Centralized control. The printing device 60 includes a detector 62 for detecting the end of the wood, and ink jet print heads 64 and 66 that eject ink from below to above. The print head 64 performs black printing, and the print head 66 performs blue printing.
[0012]
The processed data creation device 40 includes a computer main body 42, a display 44, and an appropriate input device (hereinafter referred to as a keyboard 46) such as a keyboard, mouse, digitizer, and the like, according to a command value input from the keyboard 46. Data is created, and the created data is written to a storage unit (not shown). The control device 50 receives the data of the data creation device 40 via the signal line 48 and performs wood processing and printing processing.
[0013]
Next, creation of machining data by the machining data creation device 40 will be described. First, a member is input for each layer of the house 100 shown in FIG. Here, (i) in FIG. 2 (A) is the third layer (second floor roof beam), (ii) is the second layer (second floor floor beam, second floor column, first floor roof beam), (iii ) Indicates the first layer (base, first-floor pole, pillar), and various indication values are input to these images displayed on the display 44 via a keyboard 46 or the like. Next, the extension and return of the end of the horizontal member are specified. (I) of FIG. 2 (B) represents the first layer shown in (iii) of FIG. 2 (A). As shown in the drawing, when the members for each layer are input, the ends of the horizontal members are all returned. For example, as shown in (ii) of FIG. 2B, the operator designates elongation at both ends of the horizontal member 26X and designates return at both ends of the horizontal member 26Y. The operator further specifies the extension and return of the end of the horizontal member for each layer. FIG. 2C shows the elongation and return of the crossing portion of the horizontal member. (I) shows the case where the horizontal member in the horizontal direction is designated as elongated, and (ii) It represents the case where elongation is specified for the vertical frame.
[0014]
For this input value, the machining data creation device 40 determines the shape of the tenon for each column member 20. Here, prior to description of the processing for determining the tenon shape, the tenon shape will be described with reference to FIG. 3 showing a tenon pattern. The tenon is determined along the direction of the horizontal member. For example, with respect to the column member 20 (2) assembled to the horizontal member 26X in the horizontal direction shown in FIG. No. 6 (horizontal flat side) is determined, and the pattern No. 6 is applied to the column member 20 (6) to be assembled to the horizontal member 26Y in the vertical direction. 7 (vertical flat side) is determined. Further, in the column member 20 (1) assembled to the end portion of the horizontal member 26X in the horizontal direction, the pattern No. 2 (closer to the end of the side) is determined. Here, with respect to the end portion, with respect to the lateral direction (X direction), the position (I) shown in FIG. 2B is the start point, and the position (E) is the end point. Further, with respect to the vertical direction (Y direction), the position (Ii) is the start point, and the position (I5) is the end point. For example, as shown in FIG. 7, for the column member 20 having the member number (1) (1), as described above, the pattern No. 2 (closer to the horizontal half-end point) is determined, and for the column member 20 of the member number (5) shown in ( ii ) of FIG. 4 (closer to the half-horizontal start point) will be determined.
[0015]
Here, the process of determining the tenon shape by the machining data creation device 40 will be described with reference to the flowchart of FIG. First, the machining data creation device 40 holds a default (Def) designation of the extending direction of the horizontal member (S100). The default (Def) designation is “0” for the horizontal (X) direction and “1” for the vertical (Y) direction. Here, the description will be made on the assumption that the column material 20 having the member number (1) shown in FIG. First, the numbering (1: 1: Arabic numeral 1 represents the first floor) is assigned to the column member 20 of the member number (1), and the lower side processing is started (S101). Here, the variable n is set to 0, and the horizontal pattern variable Hpt (0) is reset to 0 {0000} [where n = 0 indicates a lower side, n = 1 indicates an upper side, and Hpt (0 ) Shows the horizon pattern variable of the lower side]. Next, it is determined whether or not there is a horizontal member at the lower end (S102). Here, since there is a horizontal member at the lower end (Yes in S102), the process proceeds to step 105. In this step 105, it is determined whether the horizontal member is a cross or a T-shaped intersection. However, since the column member 20 having the member number (1) is none, the step 105 is No, and the process proceeds to the step 106, where the elongation and Determine if there is a return direction specification. Here, since the extension is designated as described above with reference to (ii) of FIG. 2B (Yes in S106), the routine proceeds to step 108, where the horizon pattern variable Hpt (0) is changed to the horizon. Pattern variable Hpt (0) = 0000 and direction logical operation value of direction variable N (X, Y) meaning the extension direction [0 because the horizontal member extends in the horizontal (X) direction here] , The horizon pattern variable Hpt (0) is set to 0000.
[0016]
Next, the machining data creation device 40 determines whether the column member 20 with the member number (1) is the end of the horizontal member (S109). Here, since it is an end as shown in FIG. 2B (S109 is Yes), it is determined whether it is a start end side end (S110). Here, since it is the start side end (S110 is Yes), in step 112, the above-mentioned horizon pattern variable Hpt (0) is replaced with an OR logic value of the horizon pattern variable Hpt (0) = 0000 and 0010. The horizontal pattern variable Hpt (0) is 0010, that is, the pattern No. shown in FIG. Set to 2 (closer to the end of the side). Thereafter, it is determined whether or not the processing of the upper side has been completed (S114), but here, since the processing of the lower side has been completed (S114 is No), the process returns to Step 103 and the processing of the upper side is started. Here, n is set to 1 and the horizon pattern variable Hpt (1) is reset to 0 {0000}. Then, the same process as described above is performed to determine the shape of the upper tenon. Here, when the processing of the upper side is completed (Yes in S114), the process proceeds to step 115, and it is determined whether the processing of all the column members 20 has been completed. Here, the column member 20 with the member number (1) is determined. Since the process has been completed, step 115 is No, and the process returns to step 101 to start processing the column member 20 with the member number (2).
[0017]
After the processing of step 101 to step 105 described above is advanced for the column member 20 of this member number (2), it is determined in step 106 whether the extension and return directions are specified. Here, as shown in FIG. 2B, since the column member 20 (2) is not specified (No in S106), the process proceeds to step 107, and the direction variable N (X, Y) is set to the default (Def). ) Follow the specifications. Here, since the horizontal member 26X is in the horizontal (X) direction, it is “0”. Then, through the process of step 108, it is determined whether the end of the horizontal member (S109). Here, since it is not an end as shown in FIG. 2 (B) (S109 is No), in step 111, the relief pattern variable Hpt (0) is the above-mentioned relief pattern variable Hpt (0) = 0000 and 0110. It is replaced with an OR logic operation value, and the horizontal pattern variable Hpt (0) is 0110, that is, the pattern No. shown in FIG. 6 (horizontal flat side). Thereafter, through the process of step 114, the shape of the upper tenon of the column member 20 of the member number (2) is determined.
[0018]
Here, with respect to the column member 20 with the member number (5) shown in FIG. 2B, it is determined whether it is the end of the horizontal member after the processing from step 101 to step 108 described above is advanced (S109). Here, since it is an end (S109 is Yes), it is judged whether it is a start end side end (S110). Here, since it is the terminal end (S110 is No), in step 113, the horizontal pattern variable Hpt (0) is replaced with the logical OR value of the horizontal pattern variable Hpt (0) = 0000 and 0100. The pattern variable Hpt (0) is 0100, that is, the pattern No. shown in FIG. 4 (closer to the beginning of the horizontal half). Thereafter, the shape of the upper tenon of the column member 20 having the member number (5) is determined through the process of step 114.
[0019]
Further, for the column member 20 with the member number (6) shown in FIG. 2 (B), the processing from step 101 to step 107 is performed, and in step 108, the relief pattern variable Hpt (0) is changed to the relief pattern variable Hpt (0). ) = 0000 and the direction variable N (X, Y) meaning the extending direction [here, 1 because the horizontal member extends in the longitudinal (Y) direction] Hpt (0) becomes 0001. Then, it is determined whether the end of the horizontal member (S109). Here, since it is not an end as shown in FIG. 2 (B) (S109 is No), in step 111, the above-mentioned tenon pattern variable Hpt (0) is equal to the tenon pattern variable Hpt (0) = 0001 and 0110. It is replaced with the OR logical operation value, and the horizontal pattern variable Hpt (0) is 0111, that is, the pattern No. shown in FIG. 7 (vertical flat side). Thereafter, through the process of step 114, the shape of the upper tenon of the column member 20 of the member number (6) is determined. When the above processing is completed for all the column members 20, the tense shape data of all the column members 20 are written in the storage unit, and step 115 becomes Yes, and this tenon shape determination processing is completed.
[0020]
Next, the processing of the column member 20 by the processing machine 54 shown in FIG. 1 will be described with reference to the flowchart of FIG. First, after the processing data described above is transferred to the control device 50 via the signal line 48, the columnar material is thrown into the processing machine 54 with the south surface serving as a reference surface facing upward (Yes in S201). Here, the description will be made assuming that the column member 20 having the member number (1) shown in FIG. In the present invention, the reference plane is not the south plane, and any plane can be used as the reference plane.Although it is possible to input the reference plane not upward, for example, downward, in this embodiment, An example of performing control based on a rule that the reference surface is the south surface and the reference surface is input upward will be described. First, the control device 50 determines whether or not it is necessary to reverse the wood (S202). Here, the reversal means that the column member is rotated 90 degrees around the longitudinal direction, the clockwise rotation of 90 degrees is called +1 reversal, and the rotation of 90 degrees counterclockwise is called -1 reversal. . When reversal is necessary to perform desired processing (S202: Yes), reversal is performed by a reversing device (not shown) (S203), and the number of reversals is held in the storage unit of the control device 50 (S204). Then, it is determined whether or not the machining is performed (S205). If the machining is performed (Yes in S205), first, the lower side pattern variable Hpt (0) = 0010 created by the above-described machining data creation device is obtained. Data of upper side pattern variable Hpt (1) = 0010 is read out (S206). And based on this data, the pattern No. shown in FIG. A half-width of 2 (close to the horizontal half-end point) is formed (S207).
[0021]
Thereafter, it is determined whether the machining is completed (S210). If the machining is not completed (No in S210), the process returns to step 202, and if the column material needs to be reversed, the reversal is performed (S202-). 204). Thereafter, the judgment of whether or not the slab machining is made in step 205 is No, the process proceeds to step 208, the machining data is read, the pierced hole is drilled, and other necessary machining is performed (S209). When the reversal and processing of the column material in Step 209 are repeated, Step 210 is Yes and the processing is completed.
[0022]
Subsequently, the control device 50 starts the printing process. This printing process will be described with reference to the flowchart of FIG. First, the numbering of the wood to be printed is acquired (S302). When the processing of the numbered column material 20 is completed and the conveyance roller 80 is sent, it is determined whether the column material 20 is conveyed with the south surface down (S304). That is, since printing is performed on the south surface, it is determined whether the print heads 64 and 66 can print from the lower side. Here, when the south surface is not on the lower side (S304: No), it is reversed by the reversing device 58 so that the south surface is on the lower side (S306).
[0023]
When the end of the wood is detected by the detector 62 (S308: Yes), it is determined from the transport speed of the transport roller 80 whether the paper is transported to the print position of the wood with respect to the print heads 64 and 66. (S310). And if it is conveyed to a printing position (S310: Yes), it will be judged whether the wood which prints numbering is the 1st floor (S312). Since the column material 20 with the number “1” is for the first floor (S312: Yes), the black number “I” is printed with the black print head 64 as shown in FIG. 8A. (S314), and the process ends. On the other hand, when printing the numbered “2 1” column material, because it is for the second floor (S312: No), the blue print head 66 is used to print the blue color as shown in FIG. 8B. The number “Iichi” is printed (S316), and the process is terminated.
[0024]
In the first embodiment, the numbering that is the identification information of the arrangement position of the timber is printed in different colors for each tier, so that the timber arrangement tier can be understood immediately.
[0025]
Next, printing on wood by the wood processing apparatus according to the second embodiment of the present invention will be described. FIG. 9 is a block diagram showing the configuration of the wood processing apparatus of the second embodiment. The wood processing apparatus of the second embodiment is substantially the same as the wood processing apparatus of the first embodiment described above with reference to FIG. However, in the first embodiment, the print heads 64 and 66 for performing numbered printing on the south surface of the pillar material are disposed, whereas in the second embodiment, the print head 64S that performs printing on the south surface from the lower side. In addition to 66S, print heads 64E and 66E that perform printing from the side to the east, and print heads 64W and 66W that perform printing from the side to the west are disposed.
[0026]
Then, the black numbering “Ii” as shown in FIG. 10A showing the south surface of the column material is applied to the column material 20 for the 1st floor numbering “1 1” with the black print head 64S. In addition to printing, a black horizontal line (level identification information) LA is entered. Then, a black horizontal line LA is printed on the west surface of the column member 20 by the black print head 64W as shown in FIG. Further, a black horizontal line LA (not shown) is printed on the east surface by the black print head 64E. Similarly, the blue numbering “2 1” for the second floor is given the blue numbering “1” as shown in FIG. 10C, which shows the south surface of the column, with the blue print head 66S. In addition to printing, a blue horizontal line (level identification information) LB is entered. Then, the blue horizontal lines LB are printed on the west and east surfaces by the blue print heads 66W and 66E.
[0027]
In this second embodiment, horizontal lines (hierarchy identification information) are printed on a plurality of surfaces of wood, so that even when wood is bundled as shown in FIG. Can do.
[0028]
In the above-described embodiment, a two-story building is taken as an example. However, for example, the first floor is black, the second floor is blue, the third floor is green, It is also possible to attach it.
