DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic ink-marking method in which a laser beam is emitted vertically upward from a self-propelled body moving on a floor surface by self-propelling when the ink is marked on a ceiling.

[0002]

2. Description of the Related Art With respect to blackout of a ceiling, a so-called downward swing method is well known. In other words, the black ink on the ceiling is obtained by first applying ground ink on the floor and hanging down the plumb bob so that it matches the ground ink. Can be.

[0003] In this case, however, there is a disadvantage that the bobber vibrates due to external force such as wind, and the bobbin thread cannot be made too long from the viewpoint of handling. As shown in Japanese Patent Application Laid-Open No. H11-157, there has been proposed an apparatus in which a laser is irradiated on a ceiling.

[0004]

However, in the prior art, it is necessary to align the ink with the ground ink not only by the downward swinging but also by the laser irradiation, so that the blacking operation is troublesome. It was troublesome and troublesome.

SUMMARY OF THE INVENTION The present invention has been made in view of the above background, and has an automatic inking method capable of easily performing ink marking by automatic operation, performing work with high accuracy, and saving labor. The purpose is to provide.

[0006]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a method in which a ceiling plan is converted into coordinate data in advance, and the
Input to Yuta advance, by the computer, the self-propelled body floor surface emits a laser vertically upward moved by self and
Travel control to move to the coordinate position corresponding to the mark point
Together with the response from the self-propelled body that reached the coordinate position
The current position is displayed on the display with the mark
Then, a laser is emitted from the self-propelled body to the ceiling surface.

[0007]

According to the operation of the present invention, the self-propelled body is moved in accordance with the ceiling plan converted into coordinate data in advance, and a laser is emitted vertically upward from the self-propelled body moved to the coordinate position corresponding to the ink mark point. Thus, the ink jetting position can be indicated on the ceiling surface by the emission laser, and the ceiling ink can be determined. In other words, the work only needs to instruct the self-propelled body at the black-out point, and the black-out can be performed by an automatic operation.

[0008]

Embodiments of the present invention will be described below with reference to the accompanying drawings. FIG. 1 is a schematic configuration diagram of an automatic blackout system showing an application of a preferred embodiment of the present invention.

This automatic blackout system basically causes a laser L to be emitted vertically upward from a self-propelled body 1 which moves on a floor F of a building by self-propelling, and the laser L is applied to the ceiling R by the emitted laser L. The computer 2 forms a so-called controller, and the self-propelled body 1 is remotely controlled via a remote device 3.

The self-propelled body 1 is, as shown in FIG.
A hole 10 is formed at the center, and the laser device 11 is attached to the hole 10 so as to swing. That is, the laser device 11 is rotatable around a support shaft 12 protruding from both sides, and a weight 13 is provided below the laser device 11. This is because the emission direction of the laser L is always vertically upward. Even if the self-propelled body 1 takes an inclined posture due to the inclination of the floor F as shown in FIG. Numeral 11 has a weight 13 at its lower part, so that it can be relatively rotated around the support shaft 12 to maintain its posture, and the laser L can always be emitted vertically upward.

The computer 2 stores a top view of a building as coordinate data in advance. That is, the ceiling plan of the building, which has been converted into coordinate data in advance, is displayed on the display unit 20 of the computer 2 as coordinates, and as shown in FIG. 4, the reference points A, B, C, and D such as the positions of columns are used. The current position P0 of the self-propelled body 1 is displayed so as to be superimposed within the enclosed range. Note that the conversion of the coordinate data of the ceiling plan is performed for each floor of the building. For example, in an office building, a plurality of floors having the same area and structure are set, so that all floors are stored. Instead, one floor is used as a reference floor and converted into coordinate data.

FIG. 5 is a flow chart for explaining blackout on the ceiling, which is nothing but a control operation in the computer 2.

In the computer 2, first, the ceiling plan of the floor designated by the worker is displayed on the display unit 20 as coordinates (S1).
In addition, the ink mark points P1, P2, P
3 is performed (S2). After that, first, in order to perform ink mark at the first ink mark point P1, a travel command is transmitted to the self-propelled body 1 via the remote device 3 to start the movement (S1).
3) Then, after confirming that the vehicle has reached the blackout point P1 (S4, YES), a laser emission command is transmitted to the self-propelled body 1 to irradiate the laser L onto the ceiling surface R (S5). At this time, the self-propelled body 1 is located at the black-out point P1, and the laser L emitted from the self-propelled body 1 is always directed vertically upward. Can be shown and ceiling ink can be determined. Then, movement and laser irradiation are similarly performed for the other blackout points P2 and P3, and the process is repeated until all the blackouts are completed (S6, NO).

That is, in the method of the present invention, basically,
At the time of inking on the ceiling surface R, the ceiling plan is converted into coordinate data in advance. Then, the self-propelled body 1 that moves on the floor surface F by self-running and emits the laser beam L vertically upward is moved to a coordinate position corresponding to the marking points P1, P2, and P3.
Further, the laser L is emitted from the self-propelled body 1 to the ceiling surface R.

According to such a method, the self-propelled body 1 is moved in accordance with the ceiling plan converted into coordinate data in advance, and the self-propelled body 1 which has moved to the coordinate position corresponding to the ink mark points P1, P2, P3. , A laser L is emitted vertically upward, so that the emission laser L can indicate a black-out position on the ceiling surface R, and the ceiling black can be determined. This uses the laser L, which can be considered to go straight ahead, so that the ceiling black can be determined accurately, and high accuracy can be obtained. Here, as the work, all that is required is to convert the ceiling plan into coordinate data and input it to the computer 2, and the blackout can be performed by an automatic operation. In other words, there is no need for troublesome work such as positioning with respect to the ground ink, which is seen in the conventional method, and it is possible to achieve simple and labor-saving.

[0016]

As described in detail in the above embodiments, according to the automatic blackout method of the present invention, blackout can be performed by automatic operation. Since a laser that can be considered to travel straight ahead is used, it is accurate and has high accuracy. In addition, there is no need for troublesome work such as positioning with respect to the ground ink, which is seen in the conventional method, so that it is simple and labor saving can be achieved. In addition, the self-propelled body
