Description

[Technical field]

[0001] The present invention relates to a wood processing system that uses foundation plan data to precut wood, and a data correction program used therein. [Background technology]

[0002] Traditionally, wood used in the construction of houses and the like was processed on-site, but because this is time-consuming and requires skill, recently, the pre-cut method has been adopted in many cases, in which wood is processed in a factory before being transported to the construction site. For this pre-cut method, a system has been developed that converts design drawings into control data for a pre-cutting machine using CAM (see, for example, Patent Documents 1 and 2), and by using this system, construction can be carried out simply by assembling pre-cut wood on-site.

[0003] However, while the conventional precut processing systems described in Patent Documents 1 and 2 above can perform processing by drilling bolt holes into wood into which anchor bolts are inserted, the processing is performed based on data on design drawings. Therefore, if an error occurs between the position of the anchor bolt in the foundation constructed on site and its position on the design drawings, there is a problem in that the error cannot be addressed using only the floor plan data based on the design drawings.

[0004] To address the above errors, even if the position of the anchor bolts is measured on-site and the errors are corrected, the method of measuring the position of each anchor bolt while moving the surveying device takes time. On the other hand, when measuring using a laser distance meter, only the distance to the bolt surface can be measured, so an error occurs with the position of the central axis of the bolt. In addition, if the positions of the anchor bolts are manually input or corrected one by one in the floor plan data, it is time-consuming because there are many anchor bolts.

[0006] The present invention has an object to solve the problems of the conventional technology described above. In summary, the object of the present invention is to provide a wood processing system that not only can automatically drill holes in wood to be used for a foundation using a precut processing machine, but also can efficiently and without error input coordinates of bolt positions based on the positions of anchor bolts installed on site into the floor plan data for the processing machine, and a data correction program used therein. [Means for solving the problem]

[0007] As a means for solving the above-mentioned problems, the inventor has configured a wood processing system which automatically processes wood to be used in the foundation using a pre-cutting machine based on floor plan data of the foundation of a building, comprising: means for reading data on the distance and vertical angle from a predetermined point on a plane on which surveying instruments are placed to the surface of an anchor bolt of the foundation, means for automatically calculating coordinate data of the central axis of the anchor bolt from the data on the distance to the surface of the anchor bolt and the vertical angle and dimensional data of the anchor bolt, means for inputting a bolt position onto the floor plan data of the foundation of the building based on the coordinate of the central axis of the anchor bolt, and means for controlling the position of a drill which drills bolt holes in wood to be used in the foundation, based on the floor plan data into which the bolt position has been input in the pre-cutting machine (the effects will be described later).

[0008] The present invention can also employ a configuration including a means for reading data on the distance and vertical angle from a predetermined point on the plane on which the surveying instrument is placed to at least two or more reference points, a means for automatically calculating coordinate data of the reference points from the data on the distance to the reference points and the vertical angle, and a means for drawing a reference line connecting the two or more reference points on the floor plan data of the foundation of the building based on the coordinates of the reference points. This allows the coordinates of the bolt positions to be input to the floor plan data without deviation by matching the position of the reference point or the reference line with a predetermined point on the floor plan data.

[0009] In addition, in the present invention, a laser rangefinder that can be adjusted in vertical position and orientation can be used as the surveying instrument. This makes it possible to measure the position of the anchor bolt at the back by shining a laser beam on the anchor bolt at the back by changing the height or vertical orientation of the surveying device, even if the anchor bolts at the front and back overlap.

[0010] In addition, in the present invention, the data correction program used in the wood processing system can automatically calculate coordinate data for the central axis of the anchor bolt from data on the distance to the central axis of the anchor bolt and the vertical angle, thereby making it possible to perform data correction processing of the distance and angle data to the bolt without hassle.

[0011] In addition, in the present invention, the data correction program used in the woodworking system can automatically calculate the coordinate data of the reference point from the data of the distance to the reference point and the vertical angle, which allows the coordinate calculation of the reference point to be performed together with the coordinate calculation of the bolt position without any trouble. Effect of the Invention

[0012] The wood processing system of the present invention can convert distance and angle data to anchor bolts obtained using surveying equipment into bolt position coordinates and input them into the framing plan data for the processing machine, so that during pre-cutting, holes can be drilled without error according to the positions of the anchor bolts in the constructed foundation. In addition, the bolt position coordinates for the framing plan data can be input simultaneously for all anchor bolts, eliminating the need to input the coordinates one by one.

[0013] In addition, the wood processing system of the present invention can use a specified algorithm to correct the distance and angle data to the bolt surface obtained from the surveying equipment to the distance to the bolt's central axis, so the coordinates of the bolt's central axis can be calculated accurately. As for this data correction process, the distance and angle data of all anchor bolts can be corrected at once, so the correction work does not require much effort.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0015] "First embodiment" A first embodiment of the present invention will be described in detail below with reference to Figs. 1 to 6. Reference 1 indicates a framing plan data generating device for a processing machine, and reference 2 indicates a precut processing machine. Reference R indicates a laser range finder (optical surveying instrument), and reference B indicates an anchor bolt. Reference L indicates the coordinates of the origin, and reference P indicates the coordinates of the bolt central axis.

[0016] "Hardware configuration of wood processing system" [1] Basic configuration The hardware configuration of the wood processing system of this embodiment will be described with reference to Fig. 1. The wood processing system of this embodiment is a system that automatically processes wood to be used for a foundation using a pre-cut processing machine based on floor plan data for the foundation of a building, and includes a floor plan data generation device for processing machine 1 and a wood (including laminated lumber and solid wood) pre-cut processing machine 2 as shown in the functional block diagram of Fig. 1. These devices can be connected wirelessly or by wire so as to be able to communicate with each other, and both devices can also be configured as an integrated device.

[0017] Even if the above two devices are not connected or integrated, they can be configured to transfer data between the devices using a storage medium (USB memory, etc.). Furthermore, in the woodworking system of this embodiment, a laser range finder R is used as a surveying instrument for measuring distance and angle data to an object. In this embodiment, the laser range finder R is configured to transfer data between the devices using a storage medium (USB memory, etc.), but it can also be connected wirelessly or wired to the processing machine floor plan data generating device 1 and included in the woodworking system as shown in FIG. 1.

[0018] [2] About the floor plan data generator for processing machines [2-1] Computer terminal Next, each of the above devices will be described. The above-mentioned processing machine floor plan data generating device 1 uses a computer terminal equipped with a main memory unit 11 (memory, etc.), a calculation unit 12 (CPU, etc.), a control unit 13 (CPU, etc.), an auxiliary memory unit 14 (hard disk, SSD, etc.), a display unit 15 (output means), and an input unit 16 (input means) as shown in Fig. 1. As for this computer terminal, a notebook PC, a desktop PC, a tablet PC, a smartphone, a PDA (personal digital assistant), etc. can be used as appropriate. The hardware in the device is linked by software to serve as the storage means, input means, and output means of the device.

[0019] [2-2] Auxiliary storage section The auxiliary storage unit 14 of the processing machine floor plan data generating device 1 includes at least a floor plan data storage unit 14a, a coordinate data storage unit 14b, a distance / angle data storage unit 14c, and a data correction program storage unit 14d, as shown in FIG. 1. The floor plan data storage unit 14a stores the floor plan data for processing machines into which the coordinates of the bolt positions of the anchor bolts are input, and the original floor plan data. The coordinate data storage unit 14b stores the coordinate data of the bolt positions obtained by correcting the distance / angle data (the distance and the vertical angle data from a specific point on the plane on which the surveying equipment is arranged to the surface of the anchor bolts of the foundation). The distance / angle data storage unit 14c stores the distance / angle data from the surveying equipment (laser range finder R) to the multiple anchor bolts. The data correction program storage unit 14d stores a data correction program (described in detail later) that performs a specific process on the distance / angle data to calculate the coordinates of the central axis of each bolt.

[0020] In this embodiment, the floor plan data generating device 1 for processing machines is composed of one computer terminal, but it is also possible to adopt a distributed system such as a server-client or a cloud system to have multiple computers work together to realize the functions, and it is also possible to use external hardware (such as a web server or a database server) as part of the floor plan data generating device 1 for processing machines (not shown).

[0021] [2-3] Transmitter / receiver The above-mentioned processing machine framing plan data generating device 1 can also adopt a configuration including a transmitter / receiver for connecting to an external device so as to be able to communicate data with the external device, as shown in Fig. 1. Specifically, when connecting to a laser range finder R, a distance angle data receiving unit 17 for receiving distance angle data from the laser range finder R to the bolt surface can be provided, and when connecting to a wood processing machine 2, a framing plan data transmitting unit 18 for transmitting processing machine framing plan data into which the coordinates of the bolt positions have been input can be provided. Note that when the above-mentioned processing machine framing plan data generating device 1 is not connected to an external device, it is not necessary to provide these transmitter / receivers.

[0022] [3] About pre-cut processing machines The pre-cutting machine 2 constituting the above-mentioned wood processing system is a pre-cutting machine capable of cutting wood to a predetermined length as a foundation material and drilling bolt holes for anchor bolts based on the floor plan data for the processing machine, and at least includes a driving unit 21 (motor, etc.) that moves a drill, a drill position control unit 22 that controls the driving unit 21 so that the drill is positioned at a predetermined position on the wood, a main memory unit 23, a calculation unit 24, and an auxiliary memory unit 25 that has a floor plan data storage unit, as shown in Fig. 2. When the wood processing machine 2 is connected to the above-mentioned floor plan data generating device 1 for the processing machine, a floor plan data receiving unit 26 can also be provided.

[0023] [4] Laser rangefinder The laser range finder R used as the surveying instrument has at least a function of measuring the distance to the surface of an object by utilizing the reflection of a laser beam, and detecting the angle of the laser beam emitted from the laser range finder R to the object. Any laser range finder R known in the field of surveying instruments or measuring instruments can be used as this type of laser range finder R. The laser range finder R used in this embodiment has support legs for adjusting the vertical position (height) of the instrument body so that the emission angle of the laser beam with respect to the object can be adjusted, and the instrument body is rotatably connected to the support legs by a hinge so that the vertical direction of the laser beam can be adjusted.

[0024] The laser distance meter R can be one that not only measures the distance to an object, but also has a function of calculating the coordinates of the object from distance data with the position of the laser distance meter R as the origin. The laser distance meter R used in this embodiment is equipped with an auxiliary storage unit that can store multiple distance and angle data measured at one foundation work site, and also has a function of outputting these multiple distance and angle data as a file for each site. This allows the floor plan data generating device for processing machines to read the distance and angle data of all anchor bolts at a specific site at once.

[0025] When the laser distance meter R is connected wirelessly or wired to the landscaping plan data generating device 1 for a processing machine, a distance / angle data transmitting unit can be provided as shown in Fig. 1. Furthermore, the distance / angle data can be stored in a DB server W connected via the Internet (e.g., a cloud system), and in that case, the distance / angle data can be transmitted from the distance / angle data transmitting unit of the DB server W to the landscaping plan data generating device 1 for a processing machine.

[0026] "Software configuration of wood processing system" [1] Distance and angle data measurement First, the measurement of the anchor bolt's distance and angle data (distance and vertical angle data from a specific point on the plane on which the surveying equipment is placed to the surface of the anchor bolt in the foundation) and orientation data on the horizontal plane (angle data showing the orientation of the anchor bolt on a horizontal plane relative to the surveying equipment) will be explained as a preliminary step. A laser rangefinder is installed at a specific point on the anchor bolts in the foundation installed on-site and measurements are taken. At this time, if the anchor bolt at the back overlaps with the anchor bolt at the front, the height and vertical angle of the main body of the laser rangefinder are changed to measure so that the laser light hits the anchor bolt at the back. Measurements are also taken so that the laser light hits the center line of the anchor bolt. The obtained distance and angle data is then transferred from the laser rangefinder R to a data generation device for the processing machine.

[0027] [2] Start the software for generating floor plan data for processing machines [2-1] Starting the software and loading distance and angle data Next, the software configuration of the wood processing system will be described with reference to the process flow shown in Fig. 2. First, the processing machine plan data generation software is started by the input means of the processing machine plan data generation device 1 (step S1), and the distance and angle data to the bolt is read (step S2). The distance and angle data to be read is imported from the distance and angle data storage unit 14c of the device or from data stored in a storage medium.

[0028] [2-2] Data correction processing and coordinate data generation and output Thereafter, the input means of the device is used to perform data correction processing of the distance and angle data, and to generate and output coordinate data of the bolt position (steps S3 and S4). These processes are performed by a correction program stored in the data correction program storage unit 14d of the device, and the coordinate data of the central axis of the anchor bolt is automatically calculated from the data of the distance to the anchor bolt surface and the vertical angle, and the dimensional data of the anchor bolt (diameter data and radius data). These data correction and coordinate generation processes may be performed in stages, or may be performed simultaneously.

[0029] The algorithm of the data correction program is not limited to one specific one, but one specific example will be given. As shown in Fig. 3(a), if the distance (d1) from the main body of the laser range finder R to the surface of the anchor bolt B and the vertical angle (θ1) of the laser light are known, the horizontal distance (d2) from the center L of the laser range finder R to the surface of the anchor bolt B can be calculated by d2=d1×cosθ1. Furthermore, as shown in Fig. 3(b), since the radius (r) of the bolt is known from the dimensional data of the anchor bolt B, the distance (d) between the center L of the laser range finder R and the central axis P of the anchor bolt B can be calculated by d=d2+r. Furthermore, as shown in Fig. 3(c), if the coordinate (0,0) of the center L of the laser range finder R is taken as the origin, if the orientation (θ2) of the laser range finder R on the horizontal plane is known, the coordinates (a,b) of the central axis P of the anchor bolt can be calculated by a=d×cosθ2, b=d×sinθ2.

[0030] In this embodiment, the above data correction process and bolt position coordinate data generation and output process can be performed collectively on the distance and angle data of all anchor bolts measured on site, and by making the distance and angle data of each anchor bolt identifiable by assigning an identification mark (e.g., numbers or letters) to the data in the order measured by a laser range finder, it is possible to calculate the coordinates of each anchor bolt from the origin all at once, as shown in Fig. 4. Note that Fig. 4 is a diagram in which the corrected bolt position coordinate data is plotted on a plane, but it does not have to be output as an image, as long as it is output as a file of a data group.

[0031] [2-3] Calculating the coordinates of a reference point or a reference line In this embodiment, when the anchor distance angle data is read, data on the distance and vertical angle from a specific point on the plane on which the surveying instrument is placed to at least two or more reference points Q are also read. Then, when generating and outputting the coordinate data of the bolt position, the coordinate data of the reference point Q is automatically calculated based on the read distance angle data to the reference point Q and the direction data on the horizontal plane. Note that the "reference point" is a position coordinate that serves as a landmark other than the anchor bolt, and by matching the coordinate of the reference point Q to the corresponding position of the floor plan data, input deviation of the bolt position can be prevented. Since this "reference point" is basically a location that does not have dimensional data, the calculation process of the central axis in the correction program is not performed. Also, there may be two or more "reference points", and in that case, the "reference line" connecting the reference points Q can be automatically or manually matched to the corresponding position of the floor plan data.

[0032] [2-4] Plotting bolt positions based on floor plan data After acquiring the coordinate data of the bolt position, the framing plan data for inputting the bolt position is selected and input from the framing plan data storage unit 14a of the device, and the framing plan data is displayed (steps S5 and S6). Then, by reading the coordinate data of the bolt position shown in FIG. 4 into the displayed framing plan data, the position of the bolt center axis P is plotted (coordinate input) on the framing plan data as shown in FIG. 5 (step S8). At that time, the bolt position can be accurately plotted on the framing plan data by using the reference point Q or the reference line. It is also possible to add a function for drawing a reference line connecting two or more reference points on the framing plan data based on the coordinate of the reference point Q, which makes manual alignment easier.

[0033] As shown in FIG. 5, the layout and length of the base D placed on the foundation are input on the original floor plan data, and the bolt central axis P is arranged along the center line of the base D. After the bolt central axis P is plotted, the distance from the end of the base D to the bolt central axis P and the distance between adjacent bolt central axes P formed on the same base D are automatically calculated based on the coordinates of each base D and the coordinates of the bolt central axis P, and floor plan data for the processing machine shown in FIG. 6 is generated (step S8). Furthermore, the generated floor plan data for the processing machine is output to the confirmation screen of the device (step S9). In this embodiment, the distance between one end of the base D and the bolt central axis P required for drilling the bolt hole is calculated, but the distance from both ends of the base D to the bolt central axis P can also be calculated as necessary, and processing information required for the precut processing machine 2 can be calculated appropriately.

[0034] [2-5] Transmission processing of floor plan data for processing machines After the above-mentioned framing data for the processing machine is output on the confirmation screen, it is confirmed that there are no errors or deviations in the positions and intervals of the bolt central axes and various dimensions, and if there are no problems, a transmission input (for example, clicking the transmission button) is performed to transmit the framing data for the processing machine to the precut processing machine 2 (step S 10 , Step S 11). After the data transmission is completed, the processing machine framing plan data generating software is terminated. If the processing machine framing plan data generating device 1 and the precut processing machine 2 are not connected, data can be transferred using a storage medium such as a USB memory instead of the above transmission process.

[0035] [3] Control processing of precut processing machines The transmitted plan data for the processing machine is received by the plan data receiving unit 26 of the precut processing machine 2 shown in FIG. 1 and stored in the plan data storage unit. Then, this plan data is converted into control data for the processing device by CAM, and the precut processing is started. During the precut processing, when drilling holes in the wood that is the material for the base D, the position of the drill is moved by the driving unit 21 by a predetermined distance from the end of the base D by processing of the drill position control unit 22 based on the plan data for the processing machine, and the bolt hole is drilled. After that, the drill is moved from the position of the bolt center axis P where the hole was drilled to the position of the adjacent bolt center axis P to drill the next hole, and this is repeated in sequence to drill the bolt hole at the exact position of the base.
