Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to the structure of a coating section of a floor coating agent applicator in which an applicator for applying a coating agent solution to a floor surface is attached to a mobile body.

[Conventional technology]

In the above-mentioned coating machine, conventionally, for example, JP-A-63-315
As shown in Japanese Patent No. 169, a drive mechanism for vertically vibrating the applicator was provided, and the coating layer could be thinned by the diffusion effect caused by the vertical vibration of the applicator.

[Problem to be solved by the invention]

Conventionally, foaming occurs in the coating agent solution on the floor due to the vertical vibration of the applicator, and the coating layer dries with the foam remaining, resulting in a poor finish such as becoming cloudy or having a rough surface. was there.

SUMMARY OF THE INVENTION An object of the present invention is to provide a coating machine that can reduce the thickness of the coating while suppressing bubbling and making the coating uniform, and further has a simple structure.

[Means to solve the problem]

In order to achieve the purpose of the applicator structure of the floor coating agent applicator according to the present invention, the applicator for applying the coating agent solution is arranged in a loop-forming state in plan view and is arranged in a dispersed state in the vertical direction of the machine. An eccentric rotary cam is attached to the mobile body in a suspended and supported state via an elastic rod, and is rotatable around the vertical axis of the body located inside the loop formed by the elastic rod in a plan view. The elastic rod is attached to the eccentric rotating cam so as to be freely drivable, and is fitted onto the eccentric rotating cam so as to be vertically slidable, and the elastic rod is bent and stretched by the rotating force of the eccentric rotating cam, thereby causing the applicator to vibrate vertically. The applicator is characterized in that the applicator is provided with a circular recessed portion for transmitting the amount of water to the applicator. The functions and effects thereof are as follows.

[For production]

When the eccentric rotating cam is driven, the rotating force of the rotating cam is transmitted to the applicator through the circular recess, and since the rotating cam is an eccentric cam, the applicator bends and deforms each of the plurality of elastic rods. While rotating, the eccentric rotary cam rotates along the floor surface with the eccentric distance of the eccentric rotary cam as the rotation radius around the rotation axis of the eccentric rotary cam. As the applicator rotates, the elastic rod repeatedly bends and deforms and stretches and restores the applicator, repeatedly raising and lowering the applicator. It moves up and down against the aircraft while sliding against the eccentric rotating cam in the recessed part. That is, simply by driving the eccentric rotary cam, the applicator rotates around the vertical axis of the machine body while vertically vibrating.

When the applicator moves rotationally instead of vertically vibrating, the applicator effectively prevents the application solution from resonating with the vertical vibration of the applicator by efficiently applying horizontal force due to the rotational movement, causing ripples due to resonance. While effectively suppressing foaming and non-uniformity of adhesion distribution caused by the coating, the coating action is performed while effectively diffusing the coating solution through both vertical vibration and rotational motion.

〔Effect of the invention〕

Due to both the vertical vibration and rotational movement of the applicator, the coating agent solution is uniformly distributed and diffused relatively widely without foaming, resulting in a uniform coating layer thickness and smooth surface, resulting in a good finish. It has become possible to obtain a good coating, and it has also become possible to improve work efficiency by speeding up drying by making the film thinner.

In addition, only the drive mechanism that drives the eccentric rotating cam is provided as a drive mechanism to enable both vertical vibration and rotational movement due to the suspension by the elastic rod and the driving action by the eccentric rotating cam. I was able to get away with it. In other words, compared to a structure in which the entire device that supports and rotates the applicator is configured to vibrate up and down, the structure can be simplified so that the number of drive mechanisms required is small, and the device can be obtained at low cost and compactly. Became.

〔Example〕

Next, examples will be shown.

As shown in FIG.
4), a coating agent tank (T) is installed inside the housing part (5) of the mobile body, a pair of heated air supply fans (F1), (F1) arranged in parallel in the lateral direction of the body, and a normal temperature air supply fan (F2). At the same time, multiple coating agent supply nozzles (

A walking-following type floor coating agent applicator is constructed by including a blower pipe (10) having a blower pipe (10). This coating machine is
A thermoplastic resin-based coating agent solution is poured into the coating agent tank (T) and stored, and the coating agent is applied to the floor by moving the aircraft by hand over a floor made of stone, wood, concrete, or chemical flooring. The detailed structure is as follows.

That is, each of the coating agent supply nozzles (6) is arranged so as to float above the floor surface, and the liquid supply hose (
1l), distribution supply device (12> and electric liquid supply pump (P)
It is connected to the coating agent tank (T) via.

The liquid supply pump (P) is controlled by the control box (4).
) is operated by the internal controller (l3),
By being configured to take out the coating agent solution from the tank (T) and send it to the distribution supply device (■2),
Each of the plurality of coating agent supply nozzles (6)... is connected to the supply amount by the liquid supply pump (P) and the distribution supply device (12).
The coating agent solution is supplied from the tank (T) and dripped onto the floor surface at a set flow rate determined by the number of distribution destinations.

The applicator (7) is located at the rear of the machine from the coating agent supply nozzle (6), and a mounting bolt ( 14) A mounting part (7a) formed by fixing a sheet metal member with..., between this mounting part (7a) and the sheet metal fuselage frame (15), as shown in Fig. 2, the fuselage is viewed from above. Four rubber rods (16) arranged in the vertical direction of the fuselage are arranged to form a square loop and are arranged in a dispersed manner.
It is attached to the fuselage frame (l5) via... That is, it is attached to the fuselage frame (15) so as to be suspended and supported via a plurality of rubber rods (16).

The height of the fuselage frame (l5) from the floor, and the height of the fuselage frame (15) and the applicator (7) so that the contact pressure of the applicator (7) with the floor surface is an appropriate value that is neither too much nor too little. The intervals for each are set. And the rotating cam (I7) placed between the attachment part (7a) and the fuselage frame (l5)
, and an electric motor (
The applicator drive mechanism (A) having the applicator (M1) is configured as shown in FIG. 3, and enables the electric motor (M1) to drive the applicator (7) in rotational motion and in vertical vibration. That is, the rotary cam (17) is configured to be supported by the fuselage frame (I5) via the electric motor (M1) by being attached to the output shaft (18) of the electric motor (M+) so as to rotate integrally therewith. and the controller (l3)
The output shaft (l8) is rotated by the electric motor (M1) which is driven and rotated by the
It is configured to be rotationally driven at a speed of 000 rpm. The rotary cam (17) is formed into an eccentric rotary cam in which the center of the cylindrical outer circumferential surface of the rotary cam (17) and the vertical axis (X) of the machine body, which is the center of rotation, are shifted in the horizontal direction,
In addition, the vertical axis (X) of the fuselage is located at the center of the square loop defined by four rubber rods (16) in plan view, and furthermore, as shown in FIG. (17
) with an inner ring (19a) fitted on the outside thereof is fixed to the upper surface side of the mounting portion (7a) via a bearing holder (20), thereby driving the rotating cam (17). The mounting portion (7a) bends and deforms the rubber rod (l6) due to the rotational force of the rotating cam transmitted by the bearing (19), and rotates the rotating cam (17) around the vertical axis (X) of the fuselage. The applicator (7) rotates along the floor surface by rotating at a radius of the eccentric distance, and the rubber rod (16) bends as the mounting portion (7a) rotates. Because the inner ring (19a) can slide up and down with respect to the rotating cam (17) and the deformation and extension restoration are repeated, the attachment part (7a) moves up and down, and the applicator (7) moves up and down. It vibrates.

In other words, the applicator (7) rotates along the floor while vibrating up and down due to the driving force from the electric motor (M+), the eccentricity of the rotating cam (17), and the deformation of the rubber rod (16). The coating agent solution from the supply nozzle (6) is applied to the floor surface in a uniform thickness.

The first air outlet (8) is located at a location on the rear side of the aircraft body from the applicator (7), and is connected to a downward opening type air guide member (2l) attached to the aircraft frame (15) at that location. It is formed by a wind guide plate (22) attached inside the wind member (21). And this pair of heated air supply fans (
As shown in FIG. ), the rotating fan main body (24) driven by the electric motor (M2) sucks room-temperature air from outside the fan case through the intake port (25) and supplies the heater hot wire (2
6) is configured to pass through the internally installed air exhaust tube part (23a) and turn it into heated hot air heated to about 60°C by a heater hot wire (26) and send it into the inside of the air guide member (2l). As a result, the first air outlet (8) directs the heated hot air from the pair of heated air supply fans (PI) and (Fl) toward the floor surface after being coated with the applicator (7). It is designed to be supplied to the public. In other words, at the point where the applicator (7) passes and no longer becomes an obstacle to the surface formation of the coating agent and the vaporization of water, the applied coating agent solution is heated with hot air, and the coating agent is plasticized and becomes mirror-like. The coating is designed to form a smooth surface and allow moisture to evaporate easily so that the coated floor surface dries quickly.

The air pipes (10) are installed in a predetermined mounting position on the rear side of the control box (4) so that the second air outlet (9) is located at the rear of the aircraft body than the first air outlet (8) and faces downward. It is installed with.

The blower pipe (10) is connected to the room temperature air supply fan (F2) via the air hose (27), and the room temperature air supply fan (F2) is powered by an electric motor (M3) fixed to the fan case (28). is operated by the controller (13), the rotating fan body (29) driven by the electric motor (M3) sucks room temperature air from outside the fan case through the intake filter (30) and blows the air. hose(
27), all of the second ventilation ports (9) are supplied with heated warm air from the normal temperature air supply fan (F2) by the first ventilation port (8). It is designed to be supplied towards the rear floor surface. That is, room temperature air is supplied to the coated floor surface after heating with heated hot air, so that the remaining moisture is quickly removed by forced drying by air blowing regardless of heating and drying.

To construct the applicator (7), as shown in FIG. 6, a rubber body (31), a sponge (32), and an applicator surface or sheet (33) are combined to form an applicator main body. There is. As the application surface forming sheet (33), woven fabric, non-woven fabric, felt, paper, leather, etc. are used. In other words, the rubber body (31) serves as a mounting member for the seat (33).
Even if the material is relatively hard and has low elasticity, the sponge (
32) provides elasticity with relatively rich cushioning properties, and the sponge (32) and sheet (33) provide wettability for containing the solution, while the sheet prevents foaming due to the intake air of the sponge (32). This is prevented by (33).

[Another example]

The number of rubber rods (l6) installed may be three or five or more. Further, instead of the rubber rod (16), a coil spring or a rod-shaped spring may be used. Therefore, the rubber rod (16) is referred to as an elastic rod (16), and the square loop formed by the arrangement of the rubber rods (16) in plan view is simply referred to as a loop in plan view.

Further, instead of aligning the driving rotation axis (X) of the rotary cam (17) with the center of the loop formed by the elastic rod (16) in plan view, it may be arranged at a location off the center. In other words, it can be implemented by placing it inside the loop in plan view.

Instead of the inner ring (19a), a circular through hole is formed in the mounting part (17a) or a cylindrical member is attached to the mounting part (17a).
7) may be constructed and implemented so that it is vertically slidably fitted onto the rotary cam (17) directly through the circular through hole or through a cylindrical member. Therefore, the inner ring (19a)
is called a circular recessed part (19a) that fits around the rotating cam (17).
