Description

TECHNICAL FIELD The present invention relates to a floor coating agent applicator in which an applicator for applying a coating agent solution to a floor surface is attached to a moving machine body.

[Conventional technology]

In the above applicator, conventionally, an applicator for applying a coating agent solution to the floor surface is attached to a moving machine body, and a drive mechanism for vibrating the applicator vertically and horizontally is provided on the moving machine body, and diffusion by vertical vibration of the applicator is provided. A floor coating agent coating machine having a structure in which the coating layer is thinned by the action is known (for example, JP-A-63-111968).

[Problems to be Solved by the Invention]

As described above, in the conventional structure that vibrates the applicator vertically and horizontally, as shown in, for example, Japanese Patent Laid-Open No. 63-315169, a structure is provided in which a drive mechanism that vibrates the applicator only vertically is provided. It is superior to the following in the following points.

That is, if the applicator has a structure in which the coating agent is thinned only by vertical vibration, the vertical vibration causes
Foaming easily occurs in the coating agent solution on the floor surface. For this reason, the coating layer dries with bubbles,
In some cases, the finish was poor, such as clouding and rough surface. On the other hand, in the case of vibrating the applicator vertically and horizontally, since the applicator vibrates vertically and horizontally, the application solution is prevented from resonating with the vertical vibration of the applicator. This is advantageous in that it is easy to suppress the foaming caused by the ripple of the coating solution.

However, even in the conventional structure in which the applicator is vibrated vertically and horizontally as described above, the vertical vibration of the applicator is still used for thinning the coating layer, and therefore the ripples of the coating solution are increased to some extent. Is inevitable.
Therefore, it was thought that some white turbidity of the coating layer could not be avoided as long as such a vertical vibration mechanism was adopted.

It is also possible to configure the applicator so that it is driven only by horizontal vibration without vertically vibrating the applicator, but this does not allow the vertical vibration of the applicator to be utilized. Diffusion cannot be performed efficiently, and it takes a lot of time and labor to form the thin film, resulting in extremely low coating efficiency.

The object of the present invention is to utilize the vertical vibration of the applicator to efficiently reduce the thickness of the coating layer, while suppressing the disturbance of the coating layer surface due to the bubbling of the coating solution as much as possible. It is an object of the present invention to provide an applicator capable of finishing a coating layer in a good condition.

[Means for Solving the Problems]

The technical means of the present invention taken to achieve the above object,
A floor coating agent applicator equipped with an applicator drive mechanism for applying a coating agent solution to a floor surface of a moving body and applying vibration to the applicator,
The applicator drive mechanism is configured to rotate the applicator along the floor while vertically vibrating the applicator, and to apply the applicator to the rear side in the machine traveling direction with respect to the application site by the applicator. There is a heating air supply means for supplying heated hot air for plasticizing the surface of the coating agent which has already been subjected to heating to give a mirror surface treatment, to the floor surface after the coating agent is applied.

[Work]

The effect of taking the above technical means is as follows.

a. Effectively preventing horizontal movement of the applicator from resonating with vertical vibration of the applicator by effectively rotating the applicator while vertically vibrating by effectively applying horizontal force. It efficiently suppresses the foaming caused by the ripple due to the resonance and the non-uniformity of the distribution of the adhered amount on the floor surface. As a result, the application solution can be efficiently spread while the application solution is effectively diffused by both the vertical vibration and the rotational movement.

b. Even if the coating layer on the floor surface after being applied by the applicator has some foaming or some surface irregularities, the heated warm air is supplied to the floor surface. Simultaneously with the drying of the coating layer, the foaming portion and the uneven portion are treated so as to have a smooth mirror-like surface as the coating agent is plasticized.

〔The invention's effect〕

I. Due to the action of a., The coating agent solution is applied in a relatively wide range while being efficiently diffused in a state where the coating agent solution is unlikely to foam due to both the vertical vibration and the rotational movement of the applicator. Therefore, compared with a device that simply vibrates the applicator up and down, resonance of the coating solution can be suppressed and foaming and surface irregularities can be suppressed as much as possible, and compared with a device that simply rotates the applicator. Can perform efficient coating work.

B. From the effect of the above b., It becomes possible to finish the surface of the coating layer to some extent, and the unevenness to some extent can be mirror-finished, and the surface of the coating layer can be finished smoothly.

C. From the effects of a. And b. Above, in addition to improving the work efficiency in reducing the thickness of the coating layer and suppressing the disturbance of the coating layer surface during the thinning operation, drying accompanying the thinning By achieving speeding up and making the surface of the coating layer mirror-like by heating, it is possible to satisfy both requirements of further improvement of work efficiency and improvement of surface finishing accuracy.
