  10-15 is explanatory drawing which shows the structure of the Y-axis apparatus 4, FIG. 10 (a) is a top view, FIG.10 (b) is a partial vertical right view, FIG. 11 is FIG.10 (a). FIG. 12 is a sectional view taken along the line II in FIG. 10A, FIG. 13 is a sectional view taken along the line JJ in FIG. 10A, and FIG. 14 is a sectional view taken along the line KK in FIG. 15 is a cross-sectional view taken along line LL in FIG. As shown in FIG. 10, the Y-axis device 4 includes a Y-axis linear guide 42 (see FIGS. 10 and 14) and a ruler head 41 that guide linear movement in the Y direction of the ruler head 41 that supports the ruler 8. The Y-axis drive device 43 or the like for driving the X-axis device 2 is horizontally mounted on the movable body 21 of the X-axis device 2 and the second movable body 31 of the second X-axis device 3, as will be described later. Move in the X direction.

  Next, the configuration of the drive system of the Y-axis linear guide 42 and the Y-axis device 4 will be described. As shown in FIG. 14, the Y-axis linear guide 42 is configured by engaging grooved wheels 42B and 42B from above and below upper and lower rail members 42A and 42A extending in the Y direction. As shown in FIGS. 10, 11 and 13, a Y-axis drive device 43 including a servo motor and a speed reducer is fixed to one end side (X-axis device 2 side) of the Y-axis device 4. A driving pulley 44 is connected to the output shaft of the shaft driving device 43. Further, as shown in FIGS. 11 and 15, a driven pulley 45 is rotatably supported on the other end side (second X axis device 3 side) of the Y axis drive device 43, and the drive side pulley 44 and A timing belt 46 is stretched between the driven pulleys 45. The tension of the timing belt 46 can be easily adjusted by adjusting the position of the housing 51A that supports the driven pulley 45 with the bolt 51B (see FIG. 15).

  Further, as shown in FIG. 14, the ruler head 41 is connected and fixed to the timing belt 46, and the ruler head 41 supports the ruler 8, so that the ruler 8 is driven and controlled by the control device 5. It is driven by the Y-axis drive device 43 to move to the target position in the Y direction. In addition, although the water-based or oil-based pen is used as the ruler 8, it is preferable that the ruled line is easily erased in order to repeatedly perform the ruler work. Therefore, the ruler 8 is preferably an aqueous pen. It is.

  Next, the attachment structure of the Y-axis device 4 to the X-axis device 2 and the second X-axis device 3 will be described. As shown in FIGS. 2 and 12, the moving body 21 of the X-axis device 2 has, as a connecting body 21A, left and right support frames 14 and 15 and a bearing 17 fitted into the support frames 14 and 15 from the outside. , 18, a shaft 16 that is supported by the bearings 17, 18 and rotates around the X-direction axis is provided. Further, conical recesses 16a and 16b are formed on both end surfaces of the shaft 16, and the nuts 19 and 20 are screwed into the male screw portions on the side surfaces of the both ends of the shaft 16, thereby moving the shaft 16 in the X direction. Is regulated.

  As shown in FIGS. 10 to 12, at the end of the Y-axis device 4 on the X-axis device 2 side, there are a housing 47 that covers the connecting body 21 </ b> A from above, and walls that hang from the left and right ends in the X direction of the housing 47. On the inner side, connecting members 48 and 49 are provided in which conical convex portions 48a and 49a projecting toward the conical concave portions 16a and 16b of the shaft 16 are formed. The connecting member 48 is a hexagon socket head cap screw. When the connecting member 48 is rotated with respect to the internal thread of the hanging wall of the housing 47, the connecting member 48 advances and retreats in the X direction.

  Therefore, in a state where the conical concave portion 16b of the shaft 16 is engaged with the conical convex portion 49a of the connecting member 49, the connecting member 48 is moved in the direction of the shaft 16, and the connecting member 48 is moved to the conical concave portion 16a of the shaft 16. When the conical convex portion 48a is engaged, the Y-axis device 4 is connected to the connecting body 21A (moving body 21) of the X-axis device while the shaft 16 and the connecting members 48 and 49 are centered. Is positioned. The advance / retreat position of the connecting member 48 can be fixed by the nut 50. With such a configuration, the Y-axis device 4 is supported so as to be rotatable around the central axis of the shaft 16. Further, since the engagement is released by retracting the connecting member 48 with respect to the shaft 16, the Y-axis device 4 and the X-axis device 2 can be easily separated.

  As shown in FIGS. 6, 8, 10, and 14, the moving body 31 of the second X-axis device 3 is provided with a connecting body 31 </ b> A supported by shafts 31 </ b> B and 31 </ b> B so as to be movable in the Y direction. The shaft 38 is supported by a spherical bearing 39A attached to the coupling body 31A so as to be movable in the X direction, and a bracket 40A is fixed to the shaft 38. Therefore, by attaching the bracket 40A to the frame of the Y-axis device 4 with the mounting screw 40B, the Y-axis device 4 is easily connected and fixed to the moving body 31 of the second X-axis device 3 (see FIGS. 6 and 14). . Further, in this state, the spherical bearing 39A is fixed to the coupling body 31A by the fixing screw 39B (see FIGS. 6 and 8), but such fixing may not be performed.

  The X-axis device 2 and the Y-axis device 4 and the Y-axis device 4 and the second X-axis device 3 can be easily separated by the mounting structure of the Y-axis device 4 to the X-axis device 2 and the second X-axis device 3 as described above. Therefore, the scoring device 1 can be easily cleared after use, and the space required for storage can be reduced because it is not bulky. In addition, it can be easily transported to a place such as another ruled platen after the ruler device 1 is used, and the X-axis device 2, the second X-axis device 3, and the Y-axis device 4 are assembled to form the ruler device 1. Since it is also easy to configure, the ruler work can be performed quickly.

  Further, since the end portion of the Y-axis device 4 on the X-axis device 2 side is supported by the mounting structure so as to be rotatable around the central axis of the shaft 16 of the moving body 21 of the X-axis device 2, Even if there is a slight difference in height between the second X-axis device 3, an excessive force is not applied to the X-axis device 2 and the Y-axis device 4. Furthermore, the second X-axis device 3 side end of the Y-axis device 4 via a spherical bearing 39A attached to the coupling body 31A supported so as to be movable in the Y direction by the shafts 31B and 31B. Part of the frame is coupled to the moving body 31 of the second X-axis device 3, so that the parallelism between the X-axis device 2 and the second X-axis device 3 is not achieved (the moving body of the X-axis device 2). 21) Even if there is an angle difference between the moving direction of 21 and the moving direction of the moving body 31 of the second X-axis device 3, there is a difference in height between the X-axis device 2 and the second X-axis device 3. Or even if the perpendicularity between the second X-axis device 3 and the Y-axis device 4 is not set (the moving direction of the moving body 31 of the second X-axis device 3 and the ruled line head 41 of the Y-axis device 4). Even if the angle formed by the moving direction is not a right angle), it is impossible for the second X-axis device 3 and the Y-axis device 4. There is no possibility that it takes. Since the installation error is absorbed as described above, high accuracy is not required for the installation of the second X-axis device 3 installed with the X-axis device 2 as a reference. Therefore, the installation work time of the ruled line device 1 can be shortened.

  Next, correction of distortion in the XY coordinate system of the ruler apparatus 1 will be described. The ruler 8 is positioned in the X direction by the X-axis drive device 23 and the second X-axis drive device 33 that are operated synchronously, and is positioned in the Y direction by the Y-axis drive device 43, but in the control device 5 of the ruler device 1. In general, the mathematical model of the orthogonal coordinate system (XY coordinate system) and the actual operation of the ruler 8 are displaced due to factors such as installation errors. In such a case, if the control device 5 generates an operation command for each axis based on the CAD data, drives each axis, and draws a figure with the ruler 8, the figure is distorted. Therefore, it is necessary to correct such distortion.

  The correction can be performed by a technique generally used in a robot, a laser processing machine, or the like. That is, the distortion of the actual motion coordinate system with respect to the motion command based on the mathematical model of the orthogonal coordinate system (XY coordinate system) in the control device 5 may be measured and used for correction. For example, a right-angle gauge or a reference block is used. , Fixed on the surface plate 10 so that the two orthogonal sides are substantially in the X direction and the Y direction, a distance sensor is fixed at or near the position of the ruler 8, and (1) the Y-axis drive device 43 is Measurement of the distance in the Y direction with respect to a plurality of points in the substantially X direction such as the right-angle gauge when the X-axis drive device 23 and the second X-axis drive device 33 are driven without being driven, and (2) the X-axis Measurement of the distance in the X direction with respect to a plurality of points on one side in a substantially Y direction, such as the right angle gauge, when the Y axis drive unit 43 is driven without driving the drive unit 23 and the second X axis drive unit 33. What is necessary is just to do with a sensor.

  By such a measurement, the distortion of the actual motion coordinate system of the ruler 8 (the deviation angle from the right angle in the XY orthogonal coordinate system in the actual operation of the scribing apparatus 1) can be obtained. The operation command for each axis may be created by the control device 5 so as to eliminate the (shift angle). For example, in the X-axis drive device 2 and the second X-axis drive device 3 that are operated synchronously, an offset that eliminates the distortion may be given to the operation command of the second X-axis drive device. Alternatively, an offset may be given to the origin position of the second X-axis drive device 3 with respect to the origin position of the X-axis drive device 2. Further, the measurement for obtaining the correction amount as described above may be performed once after the scoring device 1 is installed on the flat surface 10a of the surface plate 10, for example.

  As shown in FIGS. 10 and 14, the ruled line head 41 includes a driving device 9 (not shown in detail). The driving device 9 reciprocates or swings the ruler 8 in the vertical direction with respect to the ruler head 41, and the vertical stroke of the ruler 8 is, for example, about 10 mm. When the ruler work is performed while the ruler 8 is moved up and down by the driving device 9 at a frequency set according to the moving speed of the ruler 8 in the XY plane, a broken line (dot line) can be drawn. Therefore, even when the flat surface 10a of the surface plate 10 is scratched or the like due to repeated can manufacturing operations or the like, the ruler 8 can be moved while overcoming the irregularities, so that the ruler work Can be performed stably and reliably. Further, it is possible to suppress damage to the ruler 8 and reduce the amount of ink used by the ruler 8. In addition, by controlling the driving device 9 with the control device 5, it is possible to draw a solid line such as a one-dot chain line and a two-dot chain line, and a line different from the broken line. Workability such as positioning work for each subsequent component is improved.

  Next, a structure for positioning the main body 11 of the X-axis device 2 in a state in which the main body 11 is moved relative to the support 12 in the X direction will be described. FIG. 16 is an explanatory diagram of a configuration in which the main body 11 is moved relative to the support 12 in the X direction from the first position to be the second position, and FIG. 16A is a front view showing the first position. FIG. 16B is a front view showing the second position. FIG. 17 is a plan view showing a ruler work by the ruler device with the main body 11 in the second position.

  FIG. 16 (a) corresponds to FIG. 1 and FIG. 2, and the left and center engagement holes in the engagement holes 12a,... The state of the first position in which the center and right engaging members 11a, 11a in the engaging members 11a,... Of the main body 11 formed at three equal intervals as described above are engaged with 12a, 12a. In this state, for example, as shown in FIG. 1, the ruled line work can be performed on the left half surface of the surface plate 10 (see, for example, the ruled line DL1).

  After the ruled line work is performed in the state of the first position as described above, the connecting member 48 (see FIG. 12) is loosened to remove the Y-axis device 4 from the X-axis device 2, and the mounting screw 40B (see FIG. 14). And the Y-axis device 4 is removed from the second X-axis device 3.

  Next, as shown in FIG. 16B, the engagement members 11a,... Of the main body 11 are inserted into the center and right engagement holes 12a, 12a in the engagement holes 12a,. The middle left and center engaging members 11a, 11a are engaged to form the second position. In this state, the main body 11 of the X-axis device 2 moves relative to the support 12 fixed on the surface plate 10 in the X direction.

  To correspond to the main body 11 of the X-axis device 2 in the second position, the second X-axis device 3 is also moved relative to the X direction from the state shown in FIG. 1 to the state shown in FIG. It is fixed on the surface plate 10 by the magnet base 7, which is the attaching means 6. Then, the connecting member 48 (see FIG. 12) is tightened to connect the Y-axis device 4 to the X-axis device 2, and the mounting screw 40B (see FIG. 14) is tightened to connect the Y-axis device 4 to the second X-axis device. 3 is connected. Even in the state of the second position, if the distortion in the XY coordinate system is corrected, the shape accuracy of the figure drawn by the ruled line work on the right half surface is improved.

  After the ruler device 1 is assembled in the second position as described above, for example, as shown in FIG. 17, a ruler work can be performed on the right half surface of the surface plate 10 (see, for example, the ruled line DL2). According to the configuration in which the ruler device 1 can relatively move in the X direction to perform the ruler work, the drawing range of the ruler 8 can be extended in the X direction. For example, with the X-axis device 2 and the second X-axis device 3 having a stroke in the X direction of about 3 m, the drawing range in the X direction can be set to about 6 m. That is, the ruler apparatus 1 having a wide drawing range can be obtained with a more compact configuration.

  In the ruler apparatus 1 in the above description, the ruler tool 8 is automatically replaced or manually replaced, and a line of different colors is drawn by the different ruler tools 8,... It is possible to improve workability such as positioning work of each part after the ruled line work.

  In the above description, the Y-axis device 4 is horizontally mounted on the X-axis device 2 and the second X-axis device, and the Y-axis device 4 is driven in the X direction by the X-axis drive device 23 and the second X-axis drive device 33. Although the configuration has been described, the present invention is not limited to such a configuration. For example, when the stroke of the Y-axis device 4 is small, the second X-axis device 3 may be omitted.
