DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a blackout device, and more particularly to a blackout device using laser light.

[0002]

2. Description of the Related Art When processing, installation of equipment or devices on a ceiling surface or a wall surface, inking work on the ceiling surface or wall surface is performed in order to determine the processing or the position of the device. When performing sumi-marking, for example, summing on the ceiling surface,
Draw a reference line on the floor, etc., and measure the length of the reference position on the floor, which corresponds to the marking position for processing or installation of equipment on the ceiling, starting from the reference line. Set. At this reference position, for example, a blackout device that irradiates coaxial laser light downward and upward is installed, and the point where the lower laser light is projected on the floor is aligned with the reference position, so that the black ink on the ceiling surface can be accurately detected. I'm looking for an out position. However, in such a blackout device, when obtaining a plurality of blackout positions, the blackout work must be performed while moving the blackout device at a plurality of reference positions set on the floor surface. bad. For this reason, there has been considered a blackout device capable of rotating the laser light irradiating means in a vertical direction and a horizontal direction, and irradiating the laser light in an arbitrary direction from one reference position.

[0003]

In a blackout device in which a laser beam irradiating means is rotatable in a vertical direction and a horizontal direction, a blackout device is required to obtain a plurality of blackout positions from one reference position. Although it is possible to eliminate the trouble of moving, the distance and direction of the marking position from the reference position, the height from the reference position to the ceiling surface, the distance to the wall marking position, and three-dimensional coordinates, etc. Complicated work is required, such as obtaining from a plurality of drawings, such as a plan, and inputting the obtained data to a blackout device. Therefore, it is desired to further improve workability.

An object of the present invention is to improve the workability of a blackout operation.

[0005]

The inking device of the present invention comprises:
Laser beam irradiation means that can rotate in the horizontal and vertical directions, distance measurement means that receives the reflected light of the laser light and measures the distance to the reflection position of the laser light, and controls the irradiation direction of the laser light Control means, the control means comprising: device coordinates of a position where the marking device is installed; coordinates of a vertical projection point at which the marking position is suspended on a virtual horizontal plane including the device coordinates; and irradiation of laser light. Based on the geometric relationship between the elevation angle when the direction is moved in the vertical direction and the distance from the device position at this elevation angle to the position where the laser beam is projected, the irradiation direction of the laser beam is calculated from the reference azimuth direction. The above problem is solved by rotating horizontally from the virtual horizontal plane toward the ink mark-out position after horizontal rotation in the mark-out position direction.

[0006] With this configuration, the geometric coordinates are obtained from the device coordinates of the position of the blackout device and the coordinates of the vertical projection point obtained by projecting the blackout position on the virtual horizontal plane on which the device coordinates are set. The horizontal rotation angle from the reference azimuth of the irradiation direction of the laser beam to the direction of the blackout position can be calculated based on the target relationship. Furthermore, based on the elevation angle when the laser light irradiation direction is moved in the vertical direction and the distance from the device position at this elevation angle to the position where the laser light is projected, the ink is extracted from a virtual horizontal plane in the laser light irradiation direction. The rotation angle in the vertical direction toward the position can be calculated. For this reason, regardless of the distance from the blackout device to the height of the ceiling surface or the wall surface, etc., the two-dimensional coordinates of the blackout position obtained by setting the coordinate axes on the plan view of the ceiling surface or wall surface to be blacked out are set. Ink marking can be performed by a simple operation such as inputting to a printing device. That is, the workability of the blackout operation can be improved.

At this time, the control means calculates from the geometrical relationship between the device coordinates of the position where the black-out device is installed and the coordinates of the vertical projection point hanging down the black-out position on a virtual horizontal plane including the device coordinates. When the irradiation direction of the laser beam is horizontally rotated from the reference azimuth to the mark-out position direction based on the set horizontal azimuth angle, and then the distance from the device position to the vertical projection point and the irradiation direction of the laser beam are moved in the vertical direction The laser beam irradiation direction is adjusted to the mark position based on the geometric relationship between the elevation angle of the device and the distance from the device position at this elevation angle to the reflection position of the laser beam, so that the mark on the ceiling or floor can be obtained. it can.

On the other hand, the control means is calculated from the geometrical relationship between the device coordinates of the position where the black-out device is installed and the coordinates of the vertical projection point hanging down the black-out position on a virtual horizontal plane including the device coordinates. When the laser beam irradiation direction is horizontally rotated from the reference azimuth to the blackout position direction based on the horizontal azimuth angle, and the distance from the blackout position to the vertical projection point and the laser beam irradiation direction are moved vertically. It is possible to ink on the wall surface by adjusting the irradiation direction of the laser light to the ink extraction position based on the geometric relationship between the elevation angle of the laser beam and the distance from the device position at this elevation angle to the laser light reflection position.

Further, the coordinates of the two known points are input in advance to the blackout device, and the distance between the position of the device and the known two points is measured by distance measuring means. ,
Each distance from the measured device position to two known points, the distance between two known points calculated from the coordinates of the two known points, and one of the coordinate axes and the known two points from the device position are subtracted. If the device coordinates are calculated based on the geometric relationship with the angle formed by the line, it is not necessary to determine the coordinates of the device position in advance and to carry out the inking, so that the inking device can be moved to any position. It is preferable because it can be installed.

[0024]

(Equation 7) Based on the obtained angle β, the device coordinates P are calculated in the same manner as described above.

After the setting of the apparatus coordinates P ₀ (X ₀ , Y ₀ ), as shown in FIG. 6, the start of blackout is instructed to the blackout apparatus 1 (step 111). Marking device 1, marking position P ₁
After identifying from the command at the time of inputting the coordinates that the marking is on the ceiling surface 27 or floor surface 31 (step 112), the device coordinates P ₀ (X ₀ , Y ₀ ) and the marking coordinates P ₁ (X ₁ ,

[0026]

(Equation 8) The laser beam irradiating unit 3 is horizontally rotated by the obtained horizontal azimuth angle θ ₁ to direct the laser beam irradiating direction from the reference azimuth 37 toward the vertical projection point P ₁ ′ (step 114).

As shown in FIG. 6, the start of blackout is instructed to the blackout device 1 (step 111), and it is identified that the blackout position is on the wall surface 33 (step 112).
As shown in the figure, the laser irradiation direction of the laser irradiation unit 3 of the black-out device 1 is set such that the laser beam is irradiated on the wall surface 33 for black-out in a state parallel to the floor surface 31, that is, the device position P ₀ is directed to a horizontal projection point P ₀ ′ that is vertically projected onto the wall surface 33, and this is set as a reference azimuth 38 (step 1).
23). Distance L ₀ between device position P ₀ and horizontal projection point P ₀ ′
Calculated by the distance measuring arithmetic means 15, the intersection between the horizontal line 41 passing through the perpendicular 39 of the marking position P ₈ of the wall 33 a horizontal projection point P _{0 ',} i.e. the virtual horizontal surface 2 of the marking position P ₈

A line P ₀ -P ₀ ″ connecting the device position P ₀ and the device position P _0
0 and the eggplant horizontal azimuth angle theta ₂ between the 'lines _P 0 -P ₀ connecting the' horizontal projection point _{P 0,} the distance _{L 0,} the device coordinate _P 0 _(X 0, Z
₀ ), the horizontal projection point coordinates P ₀ ′ (X ₀ , Z ₀ ) and the vertical projection point coordinates P ₀ ″ (X ₈ , Z ₀ ) are calculated by the following equation (11) (step 124).

[0033]

[Equation 11] The laser beam irradiating unit 3 is horizontally rotated by the obtained horizontal azimuth angle θ ₂ to change the laser beam irradiating direction to the horizontal projection point P ₀ ′.
From the direction to the direction of the vertical projection point P ₀ ″ (step 12

Thereafter, the start-up coordinates P₈(X₈, Z₈)When
Vertical projection point coordinates P₀(X₈, Z ₀) And the following equation
According to (12), the vertical projection point P₀"And the ink start position P₈When
Distance D₂Is calculated (step 126).

[0035]

(Equation 12) Incidentally, Z _0, as shown in FIG. 4, the height of the laser light irradiation position of the laser light irradiation direction is input in advance marking apparatus 1 from the floor surface 31 in the case of the horizontal direction.

After calculating the distance D ₂ , the blackout coordinates P ₈ (X ₈ ,
Z ₈ ), it is identified that the blackout position is above the vertical projection point P ₀ ″ (step 127), and the laser light irradiation unit 3 is rotated vertically upward to raise the laser light irradiation direction from horizontal. go, marking apparatus 1 and the laser beam to measure the distance L ₂ between the projected position by the distance measuring arithmetic unit 15 (step 128). Then, the distance D _2, the distance L ₂ and the laser light irradiation direction of the elevation _angle, [delta] ₂ of the relationship so that the following equation (13), adjust the elevation [delta] ₂ (step 129).

[0037]

(Equation 13) In this case, when _{D 2} is _{L 2} × sin [delta ₂ smaller than, smaller [delta] ₂ (step 130), _{D 2} is _{L 2} × s
If Inderuta ₂ larger, increase the [delta] ₂ (step 131), adjusted to be in the relationship of Equation 13. When it is determined that the blackout position is below the vertical projection point P ₀ ″ from the blackout coordinates P ₈ (X ₈ , Z ₈ ) (step 127), the laser beam irradiation of the black out device 1 is performed. The unit 3 is rotated vertically downward (step 132), and steps 130 to 132 are performed.

[0038] Thus, the laser beam is projected onto the marking position _{P 8} of the wall 33, it is possible to perform marking (step 133). When there are a plurality of blackout positions on the wall surface 33, as described in the blackout on the ceiling surface 27, every time the start of blackout is instructed by the key of the operation instruction keypad 25, the storage unit 17 is started. In the order entered in
Inking is performed by repeating steps 111 to 133.

As described above, according to the ink marking method of the present invention, regardless of the height from the ink marking device 1 to the height of the ceiling surface 27 or the wall surface 33, the coordinate axes are plotted on the plan view of the ceiling surface or wall surface where ink marking is performed. Can be performed by a simple operation such as inputting the two-dimensional coordinates of the black-out position _Pn obtained by setting to the black-out device 1. That is, the workability of the blackout operation can be improved.

Further, two known reference points P _S1 , P _{S1
If S2} is marked, even if the marking device 1 is installed at an arbitrary position, the reference point coordinates P _S1 (X _S1 ,
Y _S1 ) and P _S2 (X _S2 , Y _S2 ) are input, and distance measurement is performed to obtain coordinates P ₀ (X
₀ , Y ₀ ) can be calculated. In addition, if only two reference points are manually ink-marked, all other ink-marking operations can be performed by the ink-marking device 1. In the present embodiment, the reference position P ₀ has been described the case where an arbitrary position, it is also possible to install the marking apparatus to a known reference position P _0. In this case, as shown in FIG.
₀ (X ₀ , Y ₀ ) is input through the coordinate setting keypad 23 (step 134), and further, the coordinates of the reference point at the point where the reference azimuth 37 intersects the wall surface 33 perpendicularly are input (steps 135 and 136). After that, the laser beam is projected onto this reference point (step 137), and the operation instruction keypad 2
The reference direction 37 can be recognized by the reference point set key 5 (step 138).

In the present embodiment, two escape reference points P at the height of the laser beam irradiation position when the laser beam irradiation direction of the laser beam irradiation unit 3 on the wall surface 33 is set to be horizontal.
_S1 and _PS2 were used, but two known points were recorded on the floor surface 31 and on the wall surface 33 at a height other than the height of the laser light irradiation position when the laser light irradiation direction was horizontal. It is also possible to use the obtained points. In this case, since the height of the laser light irradiation position when the laser light irradiation direction is set to the horizontal direction is input to the marking device 1, the distance between the marking device 1 and the reference point is measured by the distance measurement calculating means 15. And
The value may be converted into a distance on the virtual horizontal plane 29 at the height of the laser light irradiation position when the laser light irradiation direction of the laser irradiation unit 3 is set to the horizontal direction by a trigonometric function.

In the blackout device 1 of the present embodiment, when the blackout coordinates are input, the positions of those blackout positions are also input. However, the type of input coordinates, for example, (X _n , Y _n ) coordinates are input to the ceiling surface 27.
Alternatively, the ink mark on the wall surface 33 may be identified by inputting (X _n , Z _n ) or (Y _n , Z _n ) coordinates.

In addition, in the blackout device 1 of this embodiment, blackout is executed each time the start of blackout is instructed by a key on the operation instruction keypad 25 in the order in which the blackout coordinates are input to the storage means 17. However, for example, by giving a unique number to the input blackout coordinates, it is possible to give an instruction to blackout to a desired blackout position by specifying the number.

Further, the present invention is not limited to the marking device 1 of the configuration and operation procedure of the present embodiment, but also a laser beam irradiation section rotatable in the horizontal direction and the vertical direction, and the distance of the reflection position by the reflection of the laser beam. Various configurations and operating procedures, if equipped with distance measuring means to measure, control means to calculate the distance, horizontal azimuth angle, elevation angle, etc. based on the coordinates, and control the irradiation direction of the laser light of the laser light irradiation unit Can be applied to a blackout device.
