Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method capable of temporarily visually confirming a peeling point of a finishing material such as a tile attached to a wall surface of a building.

[0002]

2. Description of the Related Art When a peeling inspection of an outer wall tile of a building is performed by an unmanned device such as an inspection robot, it is necessary to have a technique for recognizing the position of the device and accurately recognizing the tile peeling portion.

Most of the exterior wall inspection robots currently announced by major construction companies adopt a method in which a sensor such as a rotary encoder is mounted on the robot body and the position is recognized by the output thereof.

However, in such a method, it is difficult to instantaneously recognize and determine the deteriorated portion due to an error of the encoder or a time lag when outputting position information, and even if the inspection is performed by a machine, Actually, the peeling portion is manually repaired, and therefore the worker for repair cannot accurately recognize the peeling portion.

Therefore, if the peeled portion is marked with an unmanned device, the repaired portion can be visually confirmed easily, but the following problems occur.

[0006]

That is, there is no problem if all marking points are repaired, but if marking is done but repair is not performed, or if it is light repair and there is no need to peel off tiles. The marking marks are left on the wall of the building, which is not aesthetically pleasing, and the markings have to be rubbed off with a waste cloth soaked with thinner or the like each time, which requires a lot of trouble.

Therefore, for example, in Japanese Patent Laid-Open No. 62-6067, marking is performed with a colorless liquid containing a fluorescent material.
The marking position is confirmed by irradiating the headlamps attached to the worker's helmet with ultraviolet rays and causing the fluorescent material to emit light, but the worker is working while sticking to the wall, However, there was a drawback that it was difficult to confirm a wide area due to the fact that the repaired area on the entire wall surface could not be confirmed. In order to cover such a defect, it is sufficient to irradiate the whole body, but the size of the device becomes large, and it is difficult to confirm because it is blocked by daylight especially in the daytime on a sunny day.

The present invention is intended to solve the above problems, and an object thereof is to remove a finishing material which can be erased by a simple operation without needing to irradiate an ultraviolet ray for visually confirming a marking. It provides a temporary display method of the location.

[0009]

In order to achieve the above-mentioned object, the present invention provides a display method in which a peeling detection device detects a peeling position of a wall surface finish material, and a marking is attached to the peeling position so that the peeling position can be visually confirmed. The ink used for the marking is a colored ink that becomes colorless by applying an eraser. Further, a peeling detection device can be used as a preferred embodiment of applying the eraser liquid.

[0010]

According to the above construction, when the color ink is sprayed with the eraser liquid, the color-forming component becomes colorless due to the reaction with the eraser liquid, and the marking mark is erased. Moreover, when the eraser is applied by the peeling detector, the labor of the worker can be reduced.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described in detail below with reference to the drawings.

FIG. 1 shows an outer wall inspection robot used in the method of the present invention. The outer wall inspection robot is guided along a wire 1 and is rolled along the surface of an outer wall 2 composed of tiles or the like.
The housing 4 includes a housing 4 which makes rolling contact with the roller 3, a peeling point detection device 5 arranged in the housing 4, a marking device 6 and an achromatic device 7.

The detecting device 5 comprises a hammer 8 having a load detecting portion 8a at its tip and a microphone 9 arranged above the hammer 8, and these are connected to lead wires L1 and L.
It is connected via 2 to the separation determination unit 10 installed on the ground.

The marking device 6 is located below the hammer 8 and faces the outer wall 2. The spray nozzle 11 is connected to the nozzle 11 via a solenoid valve 11a. The pressure tank 12 and the tank 12 contain the marking liquid M. And the boosting pump 13 of FIG. The solenoid valve 11a is also connected to the separation determination unit 10 on the ground via a lead wire L3.

The achromatic device 7 includes a color discrimination sensor 14 facing the outer wall 2 above the detection device 5, a spray nozzle 15 approaching the sensor 14 and facing the outer wall 2, and a solenoid valve on the nozzle 15. It is composed of a pressure tank 16 containing the erasing liquid K connected through 15a and a pump 17 for increasing the pressure of the tank 16. The sensor 1
4 and the solenoid valve 15a are connected via lead wires L4 and L5 to a color discriminating section 18 installed on the ground.

The marking liquid M is a colored ink that develops color in the same manner as a normal ink, and is composed of a coloring component and a solvent, but the coloring component is chemically reacted with the eraser K to become colorless. Be done. More specifically, the color-forming component is composed of a color developer and a colorless dye, and when the color-developing agent and the colorless dye react with each other, a color-forming complex is generated and the color is developed to form a clear ink.

The erasing liquid K is composed of a desensitizing liquid polar compound and decomposes the color-forming complex of the above-mentioned color-forming component to perform a desensitizing action, resulting in colorlessness.

The outline of the inspection in the above configuration is as follows. In addition, at the time of inspection of the peeling point, the achromatic device 7
Is in a dormant state.

First, the outer wall 1 is hit with a hammer 7 while the housing 4 is guided up and down by the wire 1. When the striking sound picked up by the microphone 8 does not satisfy a predetermined criterion, the peeling determination unit 9 determines whether or not the peeling 2a has occurred on the outer wall 2, and if the peeling 2a is determined, the solenoid valve 11 is opened for a certain time, The marking liquid M contained in the pressure tank 12 is ejected through the nozzle 10 to give a colored marking M1.

Each time the inspection of the building 1 in the vertical direction is completed, the wire is moved laterally, and the procedure of performing the inspection is repeated while moving the adjacent inspection section in the vertical direction. At this point, the inspection robot remains in the set state.

Based on the inspection, repair work is carried out, and when this is completed, the achromatic device 7 is put into an operating state and the achromatic operation is performed. The inspection device 5 and the marking device 6 are in a rest state.

When the robot is driven again, the housing 4 moves up and down, and the color discrimination sensor 14 monitors the color of the outer wall 1,
In response to this signal, the color discriminating section 18 judges whether or not the marking is M1. If it is judged that the marking is present, the solenoid valve 15a is opened for a certain period of time, so that the erasing liquid K is ejected from the nozzle 15
Is sprayed to the position of the marking M1 through. Nozzle 1
The spraying range of No. 5 has a size that covers the application range of the marking M1, so that the color of the marking M1 disappears and the color of the wall surface is reproduced.

In the above embodiment, the achromatic device is built into the robot and the marking is erased by spraying the eraser K by re-driving the robot after the repair work is completed. The inspection-dedicated robot with the built-in device 6 and the decolorized robot with only the decoloring device 7 may be operated individually, or a worker can hold the spray-type decoloring solution K in his hand and perform repair work. It goes without saying that the eraser K may be sprayed onto the post-marking M1.

[0024]

As described above in detail with reference to the embodiments, in the method for temporarily displaying the peeling position of the finishing material according to the present invention, the ink used for marking is tiled by an operator by the coloring of the ink. The peeling position such as can be visually checked immediately over a wide range. Further, the color-forming component in the ink becomes colorless due to the reaction with the erasing liquid and erases the mark on the marking, which has the advantage that the appearance of the building can be restored by a simple erasing operation.
