Description

  The present invention relates to a light marking device, and more particularly to a device for marking ink by irradiating light vertically downward.

  In general, a surveying instrument such as theodolite is installed at a reference point which is a known point in surveying (for example, see Patent Document 1 below), and a predetermined direction is determined using this surveying instrument and a light reflection target such as a reflecting prism unit. And the position of the foundation structure of a building is set up by finding a new survey point at a distance and performing inking using a downward swing at the survey point.

  In addition, the light reflecting target used together with the surveying instrument is usually installed in a state of being attached to a support such as a tripod or a pile, and the laser light emitted from the surveying instrument is reflected by a retroreflecting material such as a prism. It is possible to measure the distance by a surveying instrument, and has a built-in prism for reflecting laser light and a light diffusion plate for knowing that the laser light is irradiated on the surface. It is common.

By the way, in the marking operation at the new surveying point, after setting a new surveying point using the light reflecting target, the marking is performed by hanging a swinging swing from the light reflecting target installed at the surveying point. However, since the downward swing is easily affected by the wind, there is a possibility that the ink marking accuracy may be lowered. In recent years, laser-based ink is used to perform laser beaming by irradiating laser light vertically downward. A dispensing device has been developed.

  However, when marking the basic structure of a building, first digging in the vicinity of a new survey point, and lowering or laser-type marking device within the range dug down by the floor digging work It is necessary to use, but the earth and sand generated by the floor digging are piled up beside it (because it will be used later for backfilling, so it cannot be placed in a remote place), which makes it difficult to put the core In the case where the hole is deep, it is necessary to hang the strap and then swing it down from the tension plate, which is very troublesome and requires a long time.

  Accordingly, the present invention is to solve the above-mentioned problems, and to provide a light inking device that can easily and accurately inscribe a place where floor digging work is performed.

  In view of such circumstances, the photo-inking device of the present invention includes a support, a guide rail attached to the support and extending laterally, and a movable body movably attached to the guide rail. A light reflecting target fixed to the moving body; and a light source that is directly or indirectly attached to the light reflecting target and that emits light rays downward along a vertical axis. According to this device, the light reflecting target is fixed to the moving body attached to the guide rail extending sideways from the support body, so that it is supported outside the hole even in the place where the floor digging work is performed. By installing the body and projecting the guide rail over the hole, it is possible to set the survey point above the hole and to irradiate the light vertically from above the hole as it is to perform the ink marking work Since it can be done, the labor can be greatly reduced, the work can be completed quickly, and the inking can be performed using the light beam after setting the survey point, so that the inking accuracy can be improved. .

  In the present invention, it is preferable that the light source is disposed above the moving body and the light reflecting target, and an optical path along the vertical axis is formed in the moving body and the light reflecting target. According to this, the light source is arranged above the moving body and the light reflection target, so that the light source can be easily attached and supported, and the deviation of the center of gravity of the portion supported by the moving body in the planar direction is reduced. Therefore, the light source mounting structure can be easily configured.

  In the present invention, a light source mounting table is attached and fixed above the light reflecting target, and the light beam can be irradiated along the optical path from the light source mounting table, and is detachably mounted on the optical path. It is preferable to have a centering member for confirming the optical axis. According to this, the light source is placed on the light source mounting table, the light beam is centered using the centering member attached on the optical path, and then the centering member is removed, thereby performing the ink marking operation easily. Can do. Moreover, since it is only necessary to mount the light source on the light source mounting table, a commercially available laser marking device or the like can be used as appropriate. Here, it is preferable that the centering member can be attached to a fixed position with respect to the optical path, and that a display showing a normal optical axis position is given.

  In the present invention, the light source is preferably configured to be fixed at a predetermined position with respect to the light reflecting target. According to this, an accurate inking operation can be easily performed by fixing the light source to the light reflection target.

  In the present invention, it is preferable that a weight is attached to the support body on the side opposite to the moving body. According to this, the weight balance of the moving body, the light reflection target, and the light source can be improved by the weight. Therefore, even if the amount of protrusion of the guide rail to the side is increased, the support body can be prevented from overturning and a general support body such as a commercially available tripod can be used.

  Hereinafter, embodiments of the present invention will be described together with illustrated examples. FIG. 1 is a schematic perspective view showing the overall configuration of the first embodiment of the present invention, FIG. 3 is an exploded perspective view of the main part of the present embodiment, and FIG. 4 is a perspective view showing the main part as viewed from above. is there.

  In the present embodiment, as shown in FIG. 1, a support body 1 composed of a tripod, the guide rail 2 attached to the support body 1 and extending laterally, and attached to the guide rail 2 so as to be movable. The movable body 3, the light reflection target 4 fixed to the movement body 3, and the light source 5 that is directly or indirectly attached to the light reflection target 4 and emits light rays downward along the vertical axis 4 x. Are provided.

  The support 1 is configured such that a portion (upper part) to which the guide rail 2 is attached is movable up and down. Here, the support column 1a to which the guide rail 2 is attached may be configured to be movable up and down, and the support leg 1b configured in a tripod shape may be configured to be extendable.

  The guide rail 2 can be rotated in the horizontal direction at the upper part of the support 1 and is attached in a posture extending laterally (preferably horizontally) to the support 1. Here, it is preferable that the guide rail 2 is detachably attached to the support 1. As shown in FIGS. 3 and 4, the guide rail 2 is formed by connecting and fixing two rod-shaped rail members 2 a and 2 b with a fixing member 2 c provided at the tip.

  In the case of the illustrated example, the guide rail 2 extends from the upper part of the support body 1 to the opposite side of a portion where the moving body 3 is located, and a weight 6 is attached to the opposite side portion. The weight 6 is provided to prevent the support 5 from falling over due to the weight of the guide rail 2, the moving body 3, the light reflection target 4, the light source 5, and the like, and to adjust the support balance of the support 1. It is preferable that the weight 6 is detachably attached and configured so that the amount of the weight can be increased or decreased as necessary. Further, by configuring the attachment position of the weight 6 (distance to the support 1) to be changeable (particularly, the weight 6 is configured to be slidable), fine balance adjustment can be easily performed. Furthermore, the weight 6 may be attached not to the guide rail 2 itself but to another member attached to the support body 1 so as to protrude to the opposite side to the extension direction of the guide rail.

  The moving body 3 is fitted on the guide rail 2 and attached so as to be movable in the extending direction of the guide rail. More specifically, as shown in FIG. 3, the bottom surface of the moving body 3 is formed with concave grooves 3a and 3b that are slidably fitted to the rail members 2a and 2b. Further, a holding structure for holding the moving body 3 on the guide rail 2, particularly preferably a holding structure configured to be held at a predetermined position on the guide rail 2, includes a screw hole 3c, a pressing plate 3d, and a pressing screw 3e. Is provided.

  The moving body 3 is provided with an opening 3f that constitutes the optical path, and is rotatably mounted on the bottom surface of the moving body 3 so as to face the opening 3f. A guide sleeve 3g having a shape) is mounted, and a hollow mounting screw 3h guided through the guide sleeve 3g is preferably configured to fix the light reflecting target 4 through a washer 3i. The light reflection target 4 is preferably attached to the moving body 3 via a posture adjuster 7. The posture adjuster 7 includes posture adjusting screws 7a, 7b, and 7c, and the posture of the light reflecting target 4 can be appropriately adjusted by rotating these posture adjusting screws.

  The light reflecting target 4 is a target body 4a including a retroreflecting material such as a reflecting prism for reflecting laser light used for surveying in the incident direction, a light diffusing plate for making the irradiation position of the laser light visible. And a support frame 4b for supporting and fixing the target body 4a. As shown in FIGS. 3 and 4, the support frame 4 b is formed with an upper hole 4 c and a lower hole 4 d along a vertical axis 4 x extending vertically. The extension shaft 4x is configured to pass behind the target body 4a. The vertical axis 4x is preferably configured to pass through a reflection reference point which is a virtual reflection position when it is assumed that the laser beam reflected by the target body 4a is specularly reflected. However, the vertical axis 4x may actually be configured to pass through a point corresponding to the reflection reference point (a point having a predetermined positional relationship with the reference point).

  A centering member (pin) 4e is detachably attached to the upper opening of the lower hole 4d of the support frame 4b. The centering member 4e is formed with a cross-shaped core position display mark on the head, and sets the optical axis as an axis when the laser beam is irradiated along the vertical axis 4x as will be described later. Used for. The centering member 4e is removed during the ink marking operation using light rays.

  A mounting table (leveling table) 8 is mounted on the light reflecting target 4. The mounting table 8 is preferably made of a flat plate-like material, and is mounted and fixed so as to be in a horizontal position on the light reflection target 4. A through hole 8 a for forming the optical path is formed in the center of the mounting table 8. However, if the mounting table 8 is made of a material that transmits light emitted from the light source 5 (for example, an acrylic resin, a polycarbonate resin, or the like), the through hole 8 can be made unnecessary.

  The light source 5 is not particularly limited. In the illustrated example, the light source 5 is constituted by a portable laser marking machine. Since many of these types of laser marking machines are equipped with a level 5a, a horizontal posture can be obtained via the mounting table 8 by operating the posture adjuster 7 using the level 5a of the light source 5. It can be adjusted. Moreover, it is preferable that the light source 5 has a function of automatically aligning the irradiation direction of the laser light in the vertical direction even if the installation location is not horizontal. When the light source 5 is placed on the mounting table 8 and irradiated with laser light, the through hole 8a, the upper hole 4c, the lower hole 4d, the through hole 7d of the attitude adjuster 7, the opening 3f of the moving body 3, and the mounting screw 3h The laser beam is configured to be irradiated vertically downward through an optical path formed by the shaft hole 3j.

  At this time, when the centering member 4e is attached to the lower hole 4d as shown in FIG. 4, the laser beam is irradiated to the head of the centering member 4e so that the optical axis passes through the axis of the optical path. You can know whether or not. When the optical axis of the laser beam is deviated from the axis, the light source 5 is moved on the mounting table 8 for adjustment.

  Since the position of the mounting screw 3h can be adjusted to some extent with respect to the main body of the moving body 3, the mounting screw 3h is adjusted so that the optical path can be formed without hindrance, and the shaft hole 3j is in the optical path. It can be adjusted to match. At this time, the guide sleeve 3g rotatably attached to the main body of the movable body 3 can change the position of the mounting screw 3h in the planar direction with respect to the main body of the movable body 3, and maintains the vertical posture of the attachment screw 3h. It has a function. When the laser beam centering operation is completed, the laser beam is irradiated vertically downward by removing the centering member 4e. The irradiation point of the laser light irradiated below this extension is the marking position.

  FIG. 2 is a schematic perspective view showing the overall configuration of the second embodiment when another light source 5 ′ different from the light source 5 of the first embodiment is used, and FIG. 5 is a portion showing a mounting structure of another light source 5 ′. It is a front view. This light source 5 ′ is fixed to the upper part of the light reflection target 4 via an attachment member 9. That is, the attachment member 9 has a lower attachment structure (an attachment male screw portion or the like, not shown) for fixing to the light reflecting target 4 at the lower portion, and an upper attachment structure for connecting to the light source 5 'at the upper portion. (Mounting screw holes and the like are not shown). For example, a shaft hole (not shown) is formed in the mounting member 9 so that the laser beam can be irradiated downward through the shaft hole.

  In the case of using the above-described photoinking device, for example, the following is performed. First, an approximate survey is performed using the light reflection target 4 together with a surveying instrument (not shown), and the approximate position of a new survey point is confirmed. Next, the ground is dug, and the support 1 is placed beside the hole formed by the dug. And it sets so that the light reflection target 4 may be arrange | positioned substantially above a hole by adjusting the position of the support body 1, the guide rail 2, and the mobile body 3. FIG. Thereafter, the azimuth and distance are set using a surveying instrument (not shown), and the positions of the guide rail 2 and the moving body 3 are finely adjusted so that the light reflection target 4 is arranged at an accurate surveying point.

  Thereafter, in the case of the first embodiment, the light source 5 is set on the mounting table 8, and after centering is performed using the centering member 4e as described above, the centering member 4e is removed, and laser light is emitted. The hole is irradiated through the optical path. In this way, since the laser light is irradiated along the vertical axis 4x, the irradiation spot in the hole becomes the marking position. Here, in the first embodiment, a simple laser marking machine can be used, and there is an advantage that compatibility with various laser marking machines is high.

  On the other hand, in the case of the second embodiment, since the light source 5 'is fixed to the light reflection target 4, the inking operation can be performed immediately without requiring a centering operation. Here, in 2nd Embodiment, the positional relationship (axial center relationship) and vertical direction of light source 5 'and the light reflection target 4 can be set correctly.

  In the present embodiment, since the light reflecting target 4 and the light sources 5 and 5 'are attached to the moving body 3 attached to the guide rail 2 projecting sideways from the support body 1, it is easy and easy even in a place where floor digging is performed. Since the ink marking can be performed accurately, the work complexity and the work time can be greatly reduced. In particular, the position of the light reflection target 4 can be freely adjusted in the radial direction and the rotation direction on the side of the support 1 by the combination of the support 1, the guide rail 2 and the moving body 3. The target 4 can be easily aligned with the survey point, and the marking can be performed very easily simultaneously with the alignment. If the guide rail 2 is set in a predetermined direction, the predetermined direction and a direction orthogonal to the predetermined direction can be set by moving the moving body 3 along the guide rail 2 and performing inking.

  It is to be noted that the lightning device of the present invention is not limited to the above-described illustrated examples, and it is needless to say that various changes can be made without departing from the gist of the present invention. For example, in the above embodiment, a laser marking machine is used as the light source. However, as long as the visibility required for marking is ensured, the laser beam is not irradiated but a normal light beam is irradiated. There may be. In addition, by installing the support 1 on both sides of the guide rail 2 and supporting the guide rail 2, the stability of the guide rail 2 and the movable body 3 can be increased, and the guide rail 2 can be lengthened. become.
