  The basic operation when forming a rectangle by irradiating a rectangular line one by one using the ceiling rectangular marking device according to the embodiment will be described below.

  First, after starting the computer 3, the CPU 30 of the computer 3 loads a laser position movement control program into the main storage device 31. Next, with the power supply of the control device 2, the main power supply of the ceiling rectangular ink decrementer 1, and the power supply of the automatic leveling table 16 being turned on, the laser is irradiated from the laser diode 14a of each laser irradiation block 14 shown in FIG. The This laser irradiation state is shown in FIG.

  Then, the automatic leveling table 16 operates according to a command from the CPU 30 to automatically adjust the horizontal level of the ceiling rectangular indicia 1, and the X and Y axis irradiation means are automatically returned to preset positions. Since the laser is projected at 360 degrees in this state, an orthogonal cross line composed of the X-axis side reference line 50 and the Y-axis side reference line 51 is formed at a position vertically above the floor surface G and the ceiling surface U. The By setting the intersection of the cross lines formed on the floor G at this time as the origin, the intersection of the cross lines formed at a position vertically above the origin becomes the ceiling side reference point P. The X-axis side reference line 50 and the Y-axis side reference line 51 forming the cross line serve as the X-axis and Y-axis references, respectively.

  Here, in order to match the origin G0 of the floor surface G of the ceiling rectangular ink removal device 1, it can be performed by the shifting mechanism of the leg portion 17, and the cross line alignment is performed by the rotation mechanism of the leg portion 17. Each can be done.

  Then, according to a command from the CPU, the control device 2 causes the three X-axis side laser irradiation units 11a, 11b, and 11c, and the two Y-axis side laser irradiation units 12a and 12b, By rotating the laser irradiation block 14 so as to overlap with the Y-axis side reference line 51, the present ceiling rectangular marking device can be used. Here, the CPU sends a measurement command signal to the light wave distance meter via the control device 2, and the light wave distance meter transmits and receives light toward the ceiling surface U, and distances to the display device 34 and the control device 2. Outputs the value D.

  In this embodiment, when the CPU receives a signal for designating the origin button G0 on the screen display with the pointing device in the input state, the CPU is forced to use the X-axis side laser irradiation unit and the Y-axis side laser irradiation unit. By rotating a certain laser irradiation block 14, the laser irradiation line is superposed on the X-axis side reference line 50 and the Y-axis side reference line 51. Thereby, the user can confirm the coincidence with the reference position each time.

As shown in FIG. 4A, the input screen displayed on the display device 34 of the computer 3 is a numerical value of the movement amount from the X-axis side reference line 50 and the Y-axis side reference line 51 on the first display screen SA. Input fields S1 and S2, numerical value input fields S3 and S4 for further parallel movement from the movement position, a movement determination button S6 for determining the amount of movement of these, the laser irradiation line for confirmation and the X-axis side reference line and Y An origin return button S7 for returning to the axis side reference line and a display field S5 for displaying a distance value D to the ceiling by the light wave distance meter are displayed, and the CPU is a purpose obtained from the numerical data in the input fields S1 to S4. (L is the difference between the distance L0 from the origin to the target position and the distances Lx and Ly from the vertical point of the laser irradiation means in the X-axis direction or the Y-axis direction) and the distance value D, The rotation angle θ) = tan ^-1 (amount of movement L) / (distance value D), and calculates the rotation angle theta of the rotary shaft 13a of the actuator 13 corresponding to the amount of movement L.

  Then, the rotation angle per pulse of the encoder 15 and the number of encoder pulses required for the amount of movement are: (rotation angle θ) / (rotation angle Ep per pulse of encoder) = (encoder required for rotation by the amount of movement L) The encoder pulse number Mp corresponding to the movement amount L is calculated according to the relationship of the pulse number Mp).

  The CPU 30 transmits the obtained encoder pulse number Mp and the drive command to the ultrasonic motor 13b in the actuator 13 to the control unit 2, and the three X-axis side laser irradiation means 11a, 11b, 11c, or two Y The ultrasonic motors 13b in the actuators 13 of the shaft side laser irradiation means 12a and 12b are driven, the rotary shaft interlocking with the ultrasonic motor 13b rotates and the laser irradiation block 14 rotates, and the encoder indicates the target position. When the encoder detects the pulse number Mp, the 1-board CPU 20 of the control unit 2 that transmits and receives detection data to and from the encoder in real time stops the ultrasonic motor 13b. By stopping the ultrasonic motor 13b with high accuracy at the target position, it is possible to irradiate the laser marking line from the laser irradiation block with high accuracy, and a high-precision rectangle is formed by combining the laser marking lines. be able to.

This state is shown in FIG. 6 by taking the Y-axis side as an example. In FIG. 6, the rotation angle θ represents the rotation angle of the Y-axis side laser irradiation unit 12 a as the rotation angle θ ₁ and the rotation angle of the Y-axis side laser irradiation unit 12 b as the rotation angle θ ₂ . . Further, in FIG. 6, the movement amount L is shown as L ₁ corresponding to the rotation angle θ ₁ and L ₂ corresponding to the rotation angle θ ₂ . As shown in FIG. 6, the moving laser irradiation line may irradiate the laser irradiation line with the Y-axis side reference line 51 as a reference, or specify the distance from other previously formed laser irradiation lines. And a new laser irradiation line can also be irradiated to the predetermined position which designated the distance from the said other laser irradiation line. The X-axis side is substantially the same as the state on the Y-axis side shown in FIG. 6, but this embodiment is different in that the number of laser irradiation lines is one more than that on the Y-axis side.

  When the maximum rectangle is divided into a plurality of rectangles, as shown in FIG. 4 (2), the maximum rectangle is formed on the second display screen SB of the input screen displayed on the display device of the computer. Numerical value input fields S8, S9 for inputting the movement amount numerical value input fields S11, S12 and the number of cells formed in the rectangle for each of the X axis and the Y axis, that is, the number of divisions of the X axis, the Y axis, A button S10 for determining division is displayed. It should be noted that the first display screen SA and the second display screen SB can be selectively used or used together depending on the application.

In this case, the CPU recognizes the divided numerical value data in the numerical value input fields S9 and S10 and the vertical distance value D displayed in S5, and the obtained distance value D and the target movement amount L (L is In the X-axis direction or the Y-axis direction, from the difference between the distance L0 from the origin to the target position and the distances Lx and Ly from the vertical point of the laser irradiation means and the number of divisions, (rotation angle θ) = tan ⁻¹ According to (movement amount L) / (distance value D), the rotation angle θ of the rotation shaft 13a in the actuator 13 corresponding to the movement amount L is calculated according to the number of divisions.

  Then, the rotation angle per pulse of the encoder 15 and the number of encoder pulses required for the amount of movement are: (rotation angle θ) / (rotation angle Ep per pulse of encoder) = (encoder required for rotation by the amount of movement L) The encoder pulse number Mp corresponding to each movement amount L is calculated according to the relationship of the pulse number Mp).

  The CPU 30 transmits the obtained encoder pulse number Mp and the rotation command of the actuator 13 to the control unit 2, and the three X-axis side laser irradiation means 11a, 11b, 11c, or the two Y-axis side laser irradiation means 12a. By rotating the actuators 12b and irradiating the laser marking lines to the target positions, all the rectangles can be formed at one time.

By obtaining the designated moving distance, that is, the moving amount L and the distance value D which is the ceiling height data from the laser irradiation position, the position of the laser irradiation line is (rotation angle θ) = tan ⁻¹ (movement The rotation angle of the rotary shaft 13a in the actuator 13 corresponding to the movement amount L is detected by the encoder 15 based on the relationship of the amount L) / (distance value D).
The CPU 30 acquires the detection data from the encoder, and calculates the rotation angle per pulse of the encoder and the number of encoder pulses required for the amount of movement by (rotation angle θ) / (rotation angle Ep per encoder pulse) = ( The CPU 30 calculates an encoder pulse corresponding to the movement amount L according to the relationship of the number of encoder pulses Mp required for the rotation by the movement amount L, and the X-axis side laser irradiation means 11a, 11b, 11c or An instruction to rotate the actuators of the two Y-axis side laser irradiation means 12a and 12b corresponding to the target position is given, and the target position is irradiated with the laser irradiation line irradiation.

When the rectangle is divided at equal intervals, for example, the X-axis reference line 50, the Y-axis reference line 51, the mth X-axis laser irradiation line, and the nth Y-axis laser irradiation line. The length of one side of the rectangle that becomes the maximum contour is represented by A (m ≧ A, A is a natural number of 2 or more) on the X-axis side, and B (n ≧ B, B is a natural number of 2 or more) on the Y-axis side. The distance which is the ceiling height data from the laser irradiation position as described above, using a numerical value divided by the number of divisions A and B to be divided into individual pieces and a numerical value of an integral multiple of the numerical value as the target movement amount. From the value D and the target movement amount L, (rotation angle θ) = tan ⁻¹ (movement amount L) / (distance value D), the rotation angle of the rotary shaft 13a in the actuator 13 corresponding to the movement amount L Is detected by the encoder 15, and the rotation angle per pulse of the encoder 15 and the amount of movement are detected. The number of encoder pulses required is determined by the relationship of (rotation angle θ) / (rotation angle Ep per encoder pulse) = (number of encoder pulses Mp required for rotation by movement amount L). The CPU calculates the pulse, and a cell is formed in the maximum rectangle by (A-1) X-axis side moving irradiation means and (B-1) Y-axis side moving irradiation means. .

  Note that, as in this embodiment, the laser irradiation line irradiated in the vertical direction among the two X-axis side laser irradiation units and the two Y-axis side laser irradiation units is the X-axis side reference line 50 or the Y-axis side. For those that coincide with the reference line 51, the values of the distance Lx and the distance Ly are 0, and the X-axis side reference line or the Y-axis side reference line forms two sides of the rectangular maximum contour as described above. Since a rectangle is irradiated, one distance Lx of the X-axis side laser irradiation means takes a negative value.

  Further, in this embodiment, the X-axis side laser irradiation line and the Y-axis side laser irradiation line are configured to irradiate at an angle that can form a laser irradiation line on the ceiling without being a laser having a spread of 360 degrees. .

  Further, in the present invention, the number of laser irradiation means is not limited to that disclosed in the embodiment, and any number of laser irradiation means that are the minimum five or more that can form a cell by dividing a rectangle are provided. Can do.
