The scoring device 18 is a device that automatically forms scribing based on the mark projected onto the work by the laser projector 14, and the scoring is manually performed by the operator based on the mark projected onto the work by the laser projector 14. It may be an apparatus for forming.

  Next, the processing operation of the ruled line work support system, that is, an example of the ruled line work control method will be described with reference to FIGS. FIG. 5 is a flowchart showing an example of the processing operation of the ruled line work support system. FIG. 6 is an explanatory diagram for explaining the processing operation of the ruled line work support system. The ruled line work support system 10 implements the processing shown in FIG. 5 by controlling the operation of each part by the control device 16 and further performing the work using each part with the assistance of the operator and the operator.

  The ruled line work support system 10 installs the workpiece 20 at a predetermined position (step S12). The position where the workpiece 20 is installed is not particularly limited, and can be various positions. For example, the workpiece 20 may be installed on a surface plate, or may be left as it is at the current position. The installation work may be executed with the assistance of an operator and an operator. When the ruled line work support system 10 detects that the work 20 has been installed, the laser scanner 12 measures the shape of the work 20 (step S14). The ruled line work support system 10 measures the shape of a necessary range of the workpiece 20 by measuring the shape of the workpiece 20 at a plurality of positions. Next, the ruled line work support system 10 combines a plurality of measured results (step S16), and obtains a measurement result of the shape of the work 20 in a necessary range. Note that the synthesis method in step S16 is not particularly limited.

  The scoring work support system 10 acquires the design data of the work 20, that is, the data of the design model 60 in parallel with the measurement of the work 20 (step S18), determines the scoring position, and superimposes it on the design data ( Step S20). That is, the ruled line work support system 10 creates data in which the ruled lines 62a, 62b, 62c, and 62d are superimposed on the design model 60 as shown in FIG.

  The scoring work support system 10 measures the shape of the workpiece 20 with the laser scanner 12 and creates data indicating the relationship between the design data of the workpiece and the scribing. After that, the measurement result and design data are centered and the reference point is determined. Is performed (step S22). That is, the shape of the measurement result is analyzed using the design model, and the center of the shape of the measurement result and the reference point are determined. The position of the core of the design model and the position of the reference point may be included as design model information, or may be determined based on an analysis of the shape.

  After scoring and indexing, the scoring work support system 10 synthesizes the shape of the measurement result and the design model 60 based on the position of the core and the position of the reference point, and shapes and designs the measurement result. The model 60 is compared (step S24). The ruled line work support system 10 determines whether there is a machining allowance when the measurement result and the design data are compared (step S26). That is, based on the comparison result, it is determined whether the workpiece 20 to be machined has a shape suitable for machining after forming a ruled line.

  When it is determined that there is no machining allowance (No in step S26), the ruled line work support system 10 performs a machining process (step S28). Here, the processing includes build-up processing for a portion where the processing cost is insufficient, and correction of the position of the reference position and the reference surface. After performing the processing, the ruled line work support system 10 determines whether remeasurement is necessary (step S29). That is, as a result of processing, it is determined whether it is necessary to measure the outer shape again. When the ruled line work support system 10 has prospered that remeasurement is not necessary (No in step S29), the process returns to step S22. The ruled line work support system 10 returns to step S12 when it is determined that the measurement needs to be measured again (Yes in step S29).

  When it is determined that there is a machining allowance (Yes in step S26), the ruled line work support system 10 inputs data including the ruled line position to the laser projector 14 (step S30). That is, the data created in step S20 is input to the laser projector 14. The scoring work support system 10 projects data including the scribing position onto the work by the laser projector 14 (step S32). Specifically, as shown in FIG. 6, a reference line 80 serving as a mark for marking is projected onto the position of the work 20 corresponding to the marking position of the design model 60. Although FIG. 6 shows a state in which only the reference line 80 corresponding to one ruled line is projected, all positions corresponding to the ruled line positions within the range that can be projected by the laser projector 14 are shown. A reference line may be projected onto the screen. Moreover, it is good also as a reference point instead of a reference line.

  After projecting the reference line at the ruled position, the ruled line work support system 10 performs the ruled line processing on the projected ruled position (the position of the reference line 80) using the ruler 18 (step S34). ), This process is terminated.

  In this way, the scoring work support system 10 measures the shape of the workpiece 20 with the laser scanner 12, and projects the mark on the scoring position with the laser projector 14 using the result, thereby simplifying the scoring work. It can be carried out. Further, the ruled line work support system 10 can display the mark with high accuracy by determining the position where the mark is projected using the shape of the workpiece measured by the laser scanner 12. That is, the deviation between the set position and the position where the mark is projected can be reduced.

  Further, the ruled line work support system 10 can simplify the apparatus configuration by using a laser scanner that performs measurement without contact and a laser projector that displays a mark without contact. Further, the ruled line work support system 10 can increase the degree of freedom of the work position. That is, it is not necessary to install on a dedicated surface plate or the like, and shape measurement and mark projection can be performed at an arbitrary position. Thereby, the freedom degree of the position which performs ruled writing work can be made high. As described above, the ruled line work support system 10 can form a ruled line on an arbitrary work with high accuracy.

  Here, it is preferable that the ruled line work support system 10 uses the target mark to align the workpiece shape measured by the laser scanner 12 and the position at which the mark is projected by the laser projector 14. Thereby, the precision of the position which projects a mark can be made higher.

  Further, the ruled work support system 10 forms a ruled line with the workpiece 20 and performs processing based on the ruled line, whereby the workpiece 20 can be processed into a machined member, for example, a vehicle compartment, a container, or the like. it can. In this manner, a machined part can be manufactured by forming a ruled line on a workpiece by the ruled line work support system 10 and the ruled line work method, and performing processing based on the ruled line. A machined part manufactured using the scoring work support system 10 and the scoring work method of the present embodiment can be a highly accurate part because a scoring with higher precision is formed by simple work. it can.

  Hereinafter, the ruled line work support system 10 using the target marks will be described with reference to FIGS. FIG. 7 is a perspective view showing an example of the target mark. FIG. 8 is a perspective view showing an example of the target mark. A target mark 90 shown in FIG. 7 has a main body 92 and a target point 94. The main body 92 is a triangular prism, and a target point 94 is provided on a rectangular surface. The target point 94 is a member formed in a color different from the surroundings. The target point 94 is preferably a color that stands out from the surroundings. It is also preferable that the target mark 90 is formed of a material in which the target point 94 reflects light and the surroundings are formed of a material that absorbs light. The target mark 90 is arranged around the workpiece 20 so that the target point 94 can be seen from the laser projector 14.

  The target mark may be a three-dimensional shape, and the shape of the main body and the number of target points are not particularly limited. The target mark is preferably configured so that the position of the target point can be specified with respect to the shape of the main body. For example, in the target mark 90a shown in FIG. 8, the main body 92a is a cube, and a target point 94a is provided at the center of each surface. Thus, by providing the target point 94a at the same position on each surface of the main body 92a of the target mark 90a, the position of the target point 94a in the main body 92a can be specified regardless of the posture of the target mark 90a.

  In addition, the target mark is preferably provided with an adhesive portion, for example, an adhesive or a magnet, on a surface in contact with an object to be installed. By providing the bonding portion, the target mark can be reliably fixed at a predetermined position.

  Next, the processing operation of the ruled line work support system 1- when the target mark is used will be described with reference to FIGS. FIG. 9 is an explanatory diagram for explaining the processing operation of the ruled line work support system. FIG. 10 is a flowchart illustrating an example of processing operation of the ruled line work support system. 11 and 12 are explanatory diagrams for explaining the processing operation of the ruled line work support system.

  First, when using the target mark 90, the target mark 90 is arrange | positioned around the workpiece | work 20 as shown in FIG. Here, the ruled line work support system 10 uses the target mark 90 located at a position visible from the laser scanner 12 and the laser projector 14 among the set target marks 90.

  Next, the flow of processing will be described with reference to FIG. Here, among the processes shown in FIG. 10, the same processes as those shown in FIG. 5 are denoted by the same step numbers, and detailed description thereof is omitted. In the present embodiment, the case where the target mark 90 is used will be described.

  The ruled line work support system 10 places the workpiece 20 and the target mark 90 at predetermined positions (step S42). The target mark 90 is arranged around the workpiece 20 as shown in FIG. The target mark 90 may be fixed at a position that does not overlap the position at which the ruled line of the workpiece 20 is formed, or may be installed at a position away from the workpiece 20. In addition, what is necessary is just to perform the installation operation | work of the target mark 90 with the assistance of an operator and an operator. When the ruled line work support system 10 detects that the workpiece 20 and the target mark 90 are installed, the laser scanner 12 measures the shapes of the workpiece 20 and the target mark 90 (step S44). That is, the laser scanner 12 measures the shape of the target mark 90 arranged around the workpiece 20 in addition to the workpiece 20. Thereby, the relative position of the workpiece 20 and the target mark 90 can be detected. The ruled line work support system 10 measures the shapes of the workpiece 20 and the target mark 90 in a necessary range by measuring the shapes of the workpiece 20 and the target mark 90 at a plurality of positions. Next, the ruled line work support system 10 synthesizes the measured results (step S16), and obtains a measurement result of the shape of the work 20 in a necessary range. Further, position information of the target mark 90 arranged around the workpiece 20 can also be obtained.

  The scoring work support system 10 acquires the design data of the work 20, that is, the data of the design model 60 in parallel with the measurement of the work 20 (step S18), determines the scoring position, and superimposes it on the design data ( Step S20).

  The scoring work support system 10 measures the shape of the workpiece 20 with the laser scanner 12 and creates data indicating the relationship between the design data of the workpiece and the scribing. After that, the measurement result and design data are centered and the reference point is determined. Is performed (step S22). After scoring and indexing, the scoring work support system 10 synthesizes the shape of the measurement result and the design model 60 based on the position of the core and the position of the reference point, and shapes and designs the measurement result. The model 60 is compared (step S24). The ruled line work support system 10 determines whether there is a machining allowance when the measurement result and the design data are compared (step S26). When it is determined that there is no machining allowance (No in step S26), the ruled line work support system 10 performs a machining process (step S28). After performing the processing, the ruled line work support system 10 determines whether remeasurement is necessary (step S29). That is, as a result of processing, it is determined whether it is necessary to measure the outer shape again. When the ruled line work support system 10 has prospered that remeasurement is not necessary (No in step S29), the process returns to step S22. The ruled line work support system 10 returns to step S12 when it is determined that the measurement needs to be measured again (Yes in step S29).

  When it is determined that there is a machining allowance (Yes in step S26), the ruled line work support system 10 inputs data including the ruled line position to the laser projector 14 (step S30). Next, the ruled line work support system 10 irradiates light from the laser projector 14 toward the target mark 90 (step S50). Specifically, the irradiation light 102 is irradiated toward the target point 94 of the target mark 90 as shown in FIG. The scoring work support system 10 detects the position of the target point 94 based on the position information of the target mark 90 with respect to the workpiece 20 acquired in step S16, and irradiates the irradiation light 102 toward the detected position. The scoring work support system 10 determines whether the target mark 90 is irradiated with light, that is, whether the target point 94 and the irradiation light 102 overlap (step S52). The determination may be performed by an operator, or may be determined by a captured image by installing a shooting function such as a camera, or may be determined by providing a sensor for detecting irradiation light on the target mark 90. . When it is determined that the target mark 90 is not irradiated with the irradiation light 102 (No in step S52), the scoring work support system 10 corrects the irradiation position (step S54) and returns to step S50. The scoring work support system 10 corrects the position of the target mark 90 relative to the position where the light is irradiated by correcting the light irradiation position so that the target mark 90 is irradiated with the irradiation light. Can be detected. Thereby, the position of the workpiece | work 20 from which the position with respect to the target mark 90 with respect to the position which irradiates light is detected can be grasped | ascertained correctly.

  When it is determined that the target mark 90 is irradiated with the irradiation light (Yes in step S52), the scoring work support system 10 projects the data including the scribing position onto the work by the laser projector 14 (step S32). Specifically, as shown in FIG. 12, a reference line serving as a mark for the ruled line is projected onto the position of the work 20 corresponding to the position of the ruled line on the design model 60. After projecting the reference line at the ruled position, the ruled line work support system 10 performs the ruled line processing on the projected ruled position (the position of the reference line 80) using the ruler 18 (step S34). ), This process is terminated.

  The scoring work support system 10 uses the target mark 90 in this way, detects the position of the target mark 90 with the laser scanner 12, identifies the relative position between the target mark 90 and the workpiece 20, and projects it with the laser projector 14. At this time, by using the target point 94 of the target mark 90 and the irradiation light 102 emitted from the laser projector 14 to align the projected position of the image, a reference line serving as a mark for the position where the ruled line is formed, The reference point can be projected onto the workpiece 20 with higher accuracy.

  The scoring work support system 10 may use three target marks 90 when detecting a predetermined surface of the work 20, but by using six or more, the three-dimensional shape of the work 20 can be grasped more accurately. it can. The scoring work support system 10 can specify the three-dimensional shape reference with higher accuracy by using five or more target marks 90, and can specify the three-dimensional shape reference with higher accuracy by using six or more target marks 90. can do.

  Further, the ruled work support system 10 forms a ruled line with the workpiece 20 and performs processing based on the ruled line, whereby the workpiece 20 can be processed into a machined member, for example, a vehicle compartment, a container, or the like. it can. In this manner, a machined part can be manufactured by forming a ruled line on a workpiece by the ruled line work support system 10 and the ruled line work method, and performing processing based on the ruled line. A machined part manufactured using the scoring work support system 10 and the scoring work method of the present embodiment can be a highly accurate part because a scoring with higher precision is formed by simple work. it can.

  Next, processing for forming a ruled line on the entire circumference of the workpiece 20 will be described with reference to FIGS. 13 to 15. FIGS. 13 to 15 are explanatory diagrams for explaining the processing operation of the ruled line work support system. First, as shown in FIG. 13, the workpiece 20 is set on the work table 110, and the target mark 90 is set around the workpiece 20. Note that D1, D2, D3, and D4 of the target mark 90 have the same reference numerals with the same orientation of the target mark 90.

  Next, the scoring work support system 10 installs the laser scanner at the positions indicated by the laser scanners 12a, 12b, 12c, 12d, 12e, 12f, and 12g, and positions of the workpiece 20 and the target mark 90 at the respective positions. Is detected. Moreover, as shown in FIG. 14, the scale bar 130 is also installed in a partial area. After measuring the shape at each position, the scoring work support system 10 synthesizes the measurement results using target marks that overlap in the regions 120a, 120b, 120c, 120d, 120e, and 120f. Thereby, it is possible to create three-dimensional shape data synthesized based on one reference.

  After acquiring the measurement results of the workpiece 20 and the target mark 90, the ruled line work support system 10 uses the target mark 90 in the same direction at the positions indicated by the laser projectors 14a, 14b, 14c, and 14d. Align, project a reference line, and project a mark as a ruled reference. In this case, one laser scanner and laser projector may be moved, or another laser scanner and laser projector may be installed at each position. Further, by using the scale bar, coordinates in the depth direction can also be detected with high accuracy.

  FIG. 16 is an explanatory diagram for explaining the processing operation of the ruled line work support system. As shown in FIG. 16, the ruled line work support system 10 is preferably provided with the target mark 90a so as to surround the entire circumference of the workpiece 20a. Thus, by arranging the target mark 90a so as to surround the entire circumference of the workpiece 20a, the three-dimensional shape of the workpiece 20a can be measured with high accuracy, and the ruled line can be formed with high accuracy.

  In the ruled line work support system 10 of this embodiment, the laser scanner 12 and the laser projector 14 are separate devices, but a single device having both a shape measurement function and a projection function may be used.
