Description

[Detailed explanation of the idea] This invention relates to a floor glue applicator.

Conventionally, when attaching floor interior materials such as linoleum, carpet, and tiles to a floor surface, glue was applied directly to the floor surface using a glue spatula made of a metal plate.

However, this application work is done in a crouched position, and since the glue is a highly viscous liquid containing modified vinyl acetate, synthetic rubber, etc. as its main ingredients, the application process requires force and can easily lead to worker fatigue. , is inefficient and requires a large number of manpower,
Moreover, there were drawbacks such as uneven coating.

In order to eliminate the above-mentioned drawbacks, the applicant first opened a glue outlet in the width direction at the bottom of the glue box, and provided an elastic material with a large number of circumferential grooves formed at equal intervals on the surface of the glue outlet. A gluing roller having a coating layer is rotatably attached, and by rolling the gluing roller along the floor surface, the glue in the circumferential groove of the gluing roller is transferred to the floor surface, and the glue is transferred to the floor surface. proposed a floor glue applicator that applies the adhesive in many parallel stripes (
Specification of Utility Model Application No. 54-8497 (Utility Application No. 56-2977
(see Japanese Utility Model Application No. 54-130428 (see Japanese Utility Model Application Publication No. 56-47768)).

However, in the case of the floor glue applicator of this prior application, when the moving speed is increased to apply glue, the glue in the circumferential groove of the glue application roller becomes difficult to transfer to the floor surface, and the glue is irregularly interrupted. Therefore, the above moving speed should be changed to 8 TIL/mi.
There was an inconvenience that the speed could not be faster than n.

This invention attempts to solve the disadvantages of the earlier invention.

Examples of this invention will be described below with reference to the drawings.

The glue box 1 has a front plate 2a formed in a downwardly sloping shape, and a side plate 2.
a frame-shaped glue box body 2 having a flange 2c at the lower end of b;
It consists of a lower frame 3 which is connected to the lower surface of the glue box main body 2, is wider than the glue box main body 2, and has a glue outlet 1a opened at the lower surface, and has a lower frame 3 on the upper surface of the glue box main body 2, which can be opened and closed. A lid 4 is provided, and a roller bracket 5 consisting of left and right side plates 5a, 5a and a rear plate 5b is fixed to the lower part of the lower frame 3, and a shaft 7 of a gluing roller 6 is rotatable on the side plates 5a, 5a. The gluing roller 6 is positioned slightly below the glue outlet 1a, and the surface of the gluing roller 6 and the roller bracket 5
A minute gap is formed between the rear plate 5b and the lower edge of the rear plate 5b.

The gluing roller 6 has a core roller 8 made of a rubber-like elastic material with low hardness, such as natural rubber, synthetic leather rubber, urethane rubber, or a foam of these materials, and a core roller 8 made of a rubber-like elastic material with high hardness. An elastic coating layer 9 in which a large number of circumferential grooves 9a are formed at equal intervals is vulcanized and bonded together with the shaft 7 to be integrated.

Doctor plate 10 located in front of this gluing roller 6
As shown in FIG. 3, this doctor plate has a notch 10a at its tip facing the circumferential groove 9a of the elastic coating layer 9 of the gluing roller 6 and having the same width as the local direction R9a. The base of 10 is rotatably supported by a shaft 11 whose both ends are fixed to the side plates 5a, 5a of the roller bracket 5, and the tip of an adjustment lever 12 fixed to the base of the doctor plate 10 is connected to the front plate of the lower frame 3. Guide plate 13 fixed to 3a
Insert the thumbscrew 1 into the arcuate slot 13a.
4, and the inclination angle of the doctor plate 10 can be adjusted.

A doctor plate-shaped dust scraping plate 15 is fixed to the inner surface of the lower frame 3 of the glue box 1 at a position crossing the middle of the glue outlet 1a and in contact with the surface of the glue roller 6.

Note that a wheel bracket 16 is provided on the front plate 2a of the glue box body 2.
A wheel 17 is attached to the side plate 2b of the glue box main body 2, and a hand handle 18 is attached to the side plate 2b of the glue box body 2 so as to be swingable back and forth, and the hand handle 18 is attached to a stopper 2d protruding back and forth from the upper part of the side plate 2b. , 2e.

In the above structure, glue is put into the glue box 1, the push handle 18 is engaged with the rear stopper 2e of the glue box 1, and the wheels 16
When lifted off the floor and moved forward in the direction of arrow P, the gluing roller 6 rotates in the direction of arrow Q due to the frictional force with the floor.
A portion of the glue on the surface of the elastic coating layer 9 of the gluing roller 6 is scraped off by the doctor plate 10, and the glue in the circumferential direction 19a is taken out from the glue box 1 and transferred to the floor surface in a striped pattern.

At this time, since the core roller 8 of the gluing roller 6 is made of a rubber-like elastic material with low hardness, and the elastic coating layer 9 is made of a rubber-like elastic material with high hardness, it can be used even if the floor surface is uneven. The gluing roller 6 is deformed to follow the unevenness, and the glue is evenly transferred to the floor surface.

Moreover, the tip of the doctor plate 10 has a circumferential groove 9a.
The glue taken out from the glue box 1 into the circumferential groove 9a forms a convex strip on the surface of the glue applying roller 6 according to the shape of the cutout 10a, so that the glue is removed from the glue box 1. Even when the adhesive roller 6 is rolled at high speed, the glue is reliably transferred to the floor surface without interruption.

Further, in the above embodiment, the rear plate 5b of the roller bracket 5 is
Since a minute gap is formed between the surface of the gluing roller 6 and the surface of the gluing roller 6, the glue remaining on the surface of the gluing roller 6 without being applied to the floor surface is not blocked by the tip of the rear plate 5b and is removed from the glue box. It is returned to within 1.

Since a dust scraping plate 15 is provided in the glue box 1 at a position in the middle of the glue outlet 1a, dust on the floor is prevented from adhering to the surface of the glue roller 6 as the glue roller 6 is transferred. When the dust enters the glue box 1, the dust is stopped by the dust scraping plate 15, and the notch 10a of the doctor plate 10 is prevented from being blocked by the dust.

When simply transporting the glue box 1, the push handle 18 is engaged with the front stopper 2d of the glue box main body 2, the push handle 18 is pushed down, and the glue roller 6 is lifted off the floor for transport. be able to.

In the above embodiment, if the adhesive force of the glue to the floor surface is strong and the glue on the surface of the gluing roller 6 is completely transferred to the floor surface, the tip of the rear plate 5b is brought into contact with the surface of the gluing roller 6. The dirt scraping board 15 may be omitted by blocking the intrusion of dirt.

Further, by detachably attaching the glue roller 6 to the glue box 1, the glue box 1 and the glue roller 6 can be easily cleaned.

Alternatively, the elastic coating layer 9 of the gluing roller 6 may be formed of a rubber-like elastic material with low hardness, and the core roller 8 may be made of metal.

Furthermore, in the above embodiment, the gluing roller 6 is rotated by friction with the floor surface, but by attaching a motor to the glue box 1 or providing wheels that roll in contact with the floor surface, it is possible to The gluing roller 6 may be driven by power transmission from a motor or wheels.

As explained above, this invention has a glue outlet opening in the width direction at the bottom of the glue box, and glue having an elastic coating layer with a large number of circumferential grooves formed at equal intervals on the surface of the glue outlet. In a floor glue applicator, a glue roller is rotatably mounted, and a doctor plate is attached to the front of the glue outlet to be in contact with the surface of the glue roller. Since a large number of notches are provided, even if the moving speed on the floor is increased, the glue is applied to the floor without interruption, and even if the moving speed is increased by 20
It can rise up to rrL/min (2, low).
