It is provided to be movable in the direction. The work table 5 is moved and positioned in the X, Y, and Z axis directions by rotationally driving servo motors (not shown) for the X, Y, and Z axes. In addition, since the structure which moves the work table 5 to a X, Y, Z-axis direction may be a well-known structure, detailed description about the structure of the work table 5 is abbreviate | omitted.

  On the base frame 3, there is provided a grinding wheel base 9 provided with a grinding wheel 7 for grinding the workpiece W so as to be movable up and down. The grinding wheel base 9 is provided so as to be movable in the U and V axis directions corresponding to the X and Y axes.

In addition, since the structure of the said grinding wheel base 9 is an already known structure, the detailed description about the structure of the grinding wheel base 9 is abbreviate | omitted.

  A main body frame 11 is erected on the rear side of the base frame 3, and a screen (projection device) 12 is provided on the upper front surface of the main body frame 11. A control box 13 is integrally provided on the side surface of the main body frame 11 so as to be thermally separated from the main body frame 11. That is, the heat generation in the control box 13 is configured to be thermally separated so as not to adversely affect the main body frame 11. A control device 15 is provided on the front side of the control box 13. Various control panels are housed inside the control box 13, and an LED light source device (not shown in FIG. 1) as a light source for illuminating (irradiating) the grinding position of the workpiece W by the grinding wheel 7 is provided. Decorated. The control device 15 controls the operation of the optical scanning grinding machine 1 and is constituted by a computer.

  As shown conceptually and schematically in FIG. 2, an upper LED light source device 17 and a lower LED light source device 19 are housed inside the control box 13. The upper LED light source device 17 includes an LED light source 31 including a plurality of LEDs 29 that emit three colors of RGB. The irradiation light emitted from the plurality of LEDs 29 in the LED light source 31 is condensed, or the irradiation light collected in advance is converted into a parallel beam and condensed again at the focal position on the emission end side, such as a collimating lens For example, the upper LED light source device 17 is provided with a collimating means 33. A cylindrical connector 34 is provided at the focal position on the emission end side. A connector 39 provided on one end side of a light guide 37 having a configuration in which a plurality of optical fibers are bundled is detachably fitted to the connector 34.

  Therefore, the irradiation light collected at the focal position on the emission end side is incident on the light guide 37 from the end face of the connector 39 and guided to the other end side of the light guide 37. The other end side of the light guide 37 is disposed at a focal position of a telecentric lens 35 as an example of a projector. Therefore, the irradiation light emitted from the other end of the light guide 37 is collimated by the telecentric lens (projector) 35. Therefore, by controlling the LED light source 31, the illuminance and toning of the LED light source 31 can be adjusted. The irradiation light from the LED light source 31 is collimated by the telecentric lens 35 and is irradiated to the half mirror 27 in the cylindrical body 25 provided on the lower side of the screen 12. Then, the grinding position of the workpiece W reflected by the half mirror 27 and ground by the grinding wheel 7 is illuminated from the vertical upper position.

  Since the configuration of the lower LED light source device 19 and the configuration of the optical system are the same as those of the upper LED light source device 17 described above, the same reference numerals are given to components having the same functions, and redundant description is omitted. .

  The irradiation light from the LED light source 31 in the lower LED light source device 19 enters the light guide 37 from the end face of the connector 39 and is guided to the other end side of the light guide 37 as described above. The other end side of the light guide 37 is disposed at the focal position of a telecentric lens 35 as a projector disposed below the grinding position of the workpiece W. Therefore, the irradiation light emitted from the other end side of the light guide 37 is converted into parallel rays by the telecentric lens (projector) 35, and the grinding position of the workpiece W is irradiated from the vertically lower position.

  With the above configuration, the transmitted light transmitted from the lower side along the contour of the grinding position of the workpiece W and the reflected light irradiated and reflected from the upper side are transmitted through the half mirror 27 in the cylindrical body 25. Then, the projection image of the grinding wheel 7 and the grinding position of the workpiece W at the grinding position of the workpiece W is enlarged and projected onto the screen 12 as in the conventional case.

  As described above, when irradiating the irradiation light emitted from the upper and lower LED light source devices 17 and 19 to the grinding position of the workpiece W, the illuminance and toning are adjustable. That is, the control device 15 is constituted by a computer and includes a CPU 38, a RAM 40, a ROM 41, an input means 43, and a display means 45. The control device 15 detects an operator in order to control ON / OFF of the upper and lower LED light source devices 17, 19 and / or ON / OFF of the display means 45 provided in the control device 15. A human body detection sensor 47 is connected.

  As shown in FIG. 1, the human body detection sensor 47 is provided, for example, on the lower front side of the screen 12. The human body detection sensor 47 turns on the LED light source devices 17 and 19 and / or the display means 45 when it is detected that an operator or the like is located within a predetermined area at the front position on the optical scanning grinding machine 1. In addition, when it is not detected, it has a function of turning OFF.

  Therefore, when the operator looks at the screen 12, the LED light source devices 17, 19 and / or the display means 45 are turned ON only when the operator is positioned at the front position, and energy saving can be achieved. is there. The human body detection sensor 47 only needs to be able to detect a human body in a predetermined area on the front surface of the optical scanning grinding machine 1, and may be provided at an appropriate position of the control box 13 or the control device 15, for example.

  The control device 15 is provided with upper light source control means 49 for controlling the ON / OFF of the upper LED light source device 17 and the illuminance and toning, as well as the ON / OFF of the lower LED light source device 19. Lower light source control means 51 for controlling the illuminance and toning is provided. In order to adjust (control) the illuminance of the upper and lower LED light source devices 17 and 19 by the upper and lower light source control means 49 and 51, the control device 15 is provided with an illuminance data memory 53. The illuminance data memory 53 is provided with an upper data memory 53A and a lower data memory 53B for the upper and lower LED light source devices 17 and 19, respectively. The upper and lower data memories 53A and 53B can be shared.

  The upper and lower data memories 53A and 53B store illuminance data associated with the material of the workpiece W, the surface reflection mode, and the visual ability of the operator. Therefore, the illuminance to irradiate the work W can be adjusted to an appropriate illuminance in accordance with the material and surface reflectance of the work W and in accordance with the visual ability of the worker.

  Further, the control device 15 is provided with a toning data memory 55. The toning data memory 55 includes an upper data memory 55A and a lower data memory 55B for the upper and lower LED light source devices 17 and 19. The upper and lower data memories 55A and 55B store toning data corresponding to the material of the workpiece W (for example, green for iron-based metal, blue for copper-based metal, etc.). Yes. Therefore, the irradiation light with respect to the surface of the workpiece W can be adjusted to an appropriate color tone, and the image of the workpiece W projected on the screen 12 can be easily seen. The upper and lower data memories 55A and 55B can be shared.

  Further, the control device 15 is provided with search means 57 for searching the illuminance data memory 53 and the toning data memory 55 corresponding to the input data inputted from the input means 43.

  In the configuration as described above, the work W is attached and fixed to the work table 5, the grinding wheel 7 is rotationally driven to repeat the vertical movement, and the work table 5 is controlled to move in the X and Y axis directions with respect to the grinding wheel 7. Thus, the contour of the workpiece W is ground. Then, irradiation light that has been converted into parallel rays by the parallel beam forming means 35 is applied to the grinding position of the workpiece W from both the upper and lower sides.

  The irradiation light from the lower side enters the cylinder 25 as transmitted light along the contour of the workpiece W. The irradiation light from the upper side enters the cylindrical body 25 as reflected light near the grinding position of the workpiece W. As described above, when reflected light or the like enters the cylindrical body 25, a color image near the grinding position of the workpiece W is enlarged and projected onto the screen 12. Therefore, the grinding state of the workpiece W can be visually observed by comparing the workpiece displayed on the screen 12 with, for example, an enlarged chart paper.

  By the way, in this embodiment, LED light source devices 17 and 19 are used as light sources for irradiating the workpiece W, and the LED light source devices 17 and 19 are thermally separated from the main body frame 11 in the optical copying grinder 1. It is provided in the control box 13 provided at the position. That is, the control box 13 is thermally separated from the main body frame 11 so that the heat generated by the control box 13 including various heat sources such as electronic devices and boards does not adversely affect the main body frame 11. . In addition, LED light source devices 17 and 19 are provided in the control box 13, and irradiation light is propagated to the telecentric lenses 35 on both the upper and lower sides by a light guide 37 in which a plurality of optical fibers are bundled.

  Therefore, the LED light source devices 17 and 19 do not have a thermal adverse effect on the main body frame 11 and the like in the optical copying grinding machine 1. Moreover, since the LED light source devices 17 and 19 generate extremely little heat as compared with a halogen lamp or the like, a cooling device may be omitted in some cases, and a heat-resistant filter used when the halogen lamp is used may be omitted. Therefore, the overall configuration can be easily simplified and downsized. Further, since the LED light source devices 17 and 19 are provided in the control box 13, the maintenance and inspection of the LED light sources 17 and 19 are easy.

  As described above, when irradiating the grinding work position of the workpiece W with the irradiation light emitted from the upper and lower LED light source devices 17 and 19, it corresponds to the material of the workpiece W and the reflection form of the surface (for example, the surface is a glossy surface). When the necessary data is input from the input means 43, the illuminance data corresponding to the input data is retrieved from the illuminance data memory 53. Based on the searched illuminance data, the illuminance of the emitted light emitted from the upper and lower LED light source devices 17 and 19 is controlled (adjusted) under the control of the upper and lower light source control means 49 and 51.

  Therefore, the color image projected on the screen 12 can be viewed with good condition.

  When the color tone data of the upper and lower LED light source devices 17 and 19 is input from the input means 43, the color adjustment data corresponding to the input data is retrieved from the color adjustment data memory 55. Then, based on the searched color adjustment data, the color adjustment of irradiation light emitted from the upper and lower LED light source devices 17 and 19 is performed. Therefore, it is possible to change the color tone of the irradiation light emitted from the upper and lower LED light source devices 17 and 19. Therefore, the color image on the screen 12 can be expressed in an easy-to-view color.

  As already understood, the illuminance and toning of irradiation light emitted from the upper and lower LED light source devices 17 and 19 and applied to the workpiece W can be performed, and a color image projected on the screen 12 is displayed on the operator. The desired illuminance and color tone can be obtained.

  The LED light source devices 17 and 19 are turned on when the human body detection sensor 47 detects a human body, and are turned off when the human body detection sensor 47 is in a non-detection state. That is, in other words, the LED light source devices 17 and 19 are turned on only when the operator is positioned within a predetermined area in front of the optical copying grinder 1 in order to view the screen 12. Therefore, the LED light source devices 17 and 19 are turned ON only when necessary, and energy saving can be achieved.

  As will be understood from the above description, in the present embodiment, the light source of the irradiation light for illuminating the workpiece W to be ground is constituted by the LED light source devices 17 and 19, and the irradiation light irradiated to the workpiece W. The illuminance of the workpiece can be set to an appropriate illuminance, and the irradiation surface of the workpiece can be set to a desired color tone by adjusting the color of the irradiation light. Therefore, it is possible to reduce the visual fatigue of an operator who looks at the screen 12.

  By the way, the present invention is not limited to the embodiment as described above, and can be implemented in various forms by making various modifications.

  For example, as shown in FIG. 4, in addition to the upper and lower LED light source devices 17 and 19, a third LED light source device 61 similar to the above LED device is provided. And the 3rd light projector 35A similar to the said light projector 35 connected to the said LED light source device 61 via the light guide 37 is provided. As shown in FIGS. 4 and 5, the third light projector 35 </ b> A can be used to illuminate the grinding position of the workpiece W obliquely upward or obliquely downward as auxiliary light. Note that it is possible to irradiate the grinding position not only from one diagonally upward direction or diagonally downward direction but also from both diagonally upward and diagonally downward directions.

  As described above, by irradiating the grinding position of the workpiece W from the diagonally upward direction, the diagonally downward direction, or the diagonally up and down direction, the grinding position becomes brighter. As shown in FIG. 5, when the upper side of the workpiece W is thinner than the lower side, the irradiation light from the lower projector 35 is shielded by the lower side of the workpiece W. However, even when the light from the lower projector 35 is blocked by the third projector 35A illuminating the grinding position of the workpiece W in an obliquely upward or downward direction, the workpiece W The shape of the grinding position can be easily confirmed.

  By the way, in the said description, each projector 35,35A and LED light source device 17,19,61 demonstrated in the relationship of 1: 1. However, as shown in FIG. 6, a common LED light source device 63 and a plurality (appropriate number) of projectors 35, 35 </ b> A may be connected via a plurality of branched light guides 65. . According to this configuration, the number of LED light source devices can be reduced as compared with the number of the plurality of projectors 35 and 35A.

  Furthermore, as shown in FIG. 7, R, G, and B single color LED light source devices 67R, 67G, and 67B are used as the LED light source devices. A branch light guide 65 branched into a plurality of branches is connected to each single color LED light source device 67R, 67G, 67B, and a branch light guide 65A branched from each branch light guide 65 is connected to each of the projectors 35, 35A. It is also possible to do. According to this configuration, it is easy to individually adjust the single color LED light source devices 67R, 67G, and 67B by adjusting means such as a volume, and the illuminance and toning can be easily adjusted.

  By the way, as a configuration for illuminating the vicinity of the grinding position of the workpiece W with a color, a so-called compound eye type illumination device provided with a plurality of red LEDs, green LEDs, and blue LEDs instead of the projectors 35 and 35A. It is also possible to adopt.

  In addition, as a structure which illuminates the grinding position of the workpiece | work W, it is also possible to use white LED, for example, without being restricted to color illumination.

  In the above description, the illuminance data memory 53 and the toning data memory 55 have been described on the assumption that data is stored in advance. However, it is also possible to change the data in the illuminance data memory 53 and the toning data memory 55 by inputting illuminance data and toning data from the input means 43 in accordance with the environment in the factory. In this case, the workpiece can be illuminated with appropriate illuminance and color matching corresponding to the surrounding environment.

  In the above description, the illuminance and toning of the upper and lower LED light source devices 17 and 19 are adjusted based on the data stored in the illuminance data memory 53 and the toning data memory 55. However, it is also possible to adopt a configuration in which the illuminance and toning of the LED light source devices 17 and 19 are adjusted using adjusting means (adjustment operation means) such as a volume. When the LED light source devices 17 and 19 are, for example, white LED light source devices, there is no need for toning, so that a configuration with a volume for adjusting illuminance can be provided, and the configuration can be simplified. It is something that can be done.

  By the way, the conventional projector 35B which illuminates the grinding position of the workpiece W from below is configured as schematically shown in FIG. That is, the projector 35B includes a telecentric lens unit 73 in a cylindrical projector body 71 having an annular cooling water passage 69 for circulating cooling water, and a halogen lamp 75 below the telecentric lens unit 73. It is a configuration. The halogen lamp 75 is set so as to enter the telecentric lens unit 73 at an irradiation angle of about 100 °.

  However, the emission angle (irradiation angle) of the illumination light emitted from the emission end of the light guide 37 is about 60 °. Therefore, when the conventional telecentric lens unit 73 is used, it is difficult to attach the end portion of the light guide 37 at the position of the halogen lamp 75 instead of the halogen lamp 75. Therefore, in this embodiment, there is provided an emission angle adjusting lens (not shown) for approximating the emission angle of the illumination light emitted from the emission end of the light guide 37 to about 100 ° in the case of the halogen lamp 75. An internal adjustment lens unit 77 is provided on the light exit end side of the light guide 37.

  Therefore, instead of the halogen lamp holder 79 holding the halogen lamp 75, a support bracket 81 is provided in the projector main body 71, so that the adjusting lens unit 77 provided on the light emitting end side of the light guide 37 is provided with the projector. It can be arranged in the main body 71. In this case, the adjusting lens unit 77 is provided on the light emitting end side of the light guide 37, and the irradiation angle of the illumination light emitted from the adjusting lens unit 77 is substantially matched to the irradiation angle of the halogen lamp 75. The lens unit 77 can be disposed at substantially the same position as the halogen lamp 75.

  Therefore, by providing the adjusting lens unit 77 on the light emitting end side of the light guide 37, it can be easily retrofitted to a conventional optical scanning grinding machine. That is, retrofit is possible.
