2. Description of the Related Art When a floor material such as a tile is attached to a floor surface, an adhesive agent is first applied to the floor surface, and then the floor material is attached onto it. When the adhesive is applied in this way, since it has high fluidity when the adhesive has a low viscosity, it can be easily sprayed by pressurizing it with a pump and discharging it from a nozzle, so that automatic application is easy. Therefore, for low-viscosity adhesives, automatic coating machines already exist, but for example, the viscosity is 100
With a high-viscosity adhesive that exceeds 00 poise, the fluidity is so low that it cannot be discharged smoothly from the nozzle even when pressure is applied by a pump. It was impossible. Therefore, for high-viscosity adhesives, manual ironing or brush coating has been required. However, since the manual application work is performed in the mid-waist state as described above, fatigue is severe, and further skill is required. Therefore, improvement in workability is naturally limited.

SUMMARY OF THE INVENTION An object of the present invention is to provide an automatic adhesive applicator which improves workability by enabling automatic application of a high viscosity adhesive.

[0004]

According to the present invention, an adhesive tank and a pump for sucking and feeding the adhesive from the adhesive tank are mounted on a carriage that can move on the floor surface. It is connected to a discharge pipe together with a compressed air tank, the discharge pipe is provided at the rear of the traveling direction of the carriage so as to cross the traveling direction, and a plurality of discharge nozzles are arranged on the side facing the floor surface of the discharge pipe. Is characterized by.

As described above, in the present invention, since the adhesive is sucked from the adhesive tank by the pump and the discharge side of the pump is connected to the discharge pipe having a plurality of nozzles together with the compressed air tank, the highly viscous adhesive is compressed. By the action of air, the apparent viscosity is temporarily reduced, and the beads are smoothly discharged into a plurality of beads to be applied to the floor surface.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. As shown in FIGS. 1 and 2, the carriage 1 is
It has a base 1a parallel to the floor surface, a front center caster 1b on the lower surface thereof in the traveling direction, and a pair of left and right wheels 1 at the rear.
c and 1c are attached. A steering handle 1d is provided on the front part of the base 1a. On the base 1a of such a trolley 1, an adhesive tank 2 filled with an adhesive having a high viscosity of 10,000 to 30,000 poise, a pump 3 including a reciprocating pump, and a compressed air tank 5 are mounted. ,
Further, a discharge pipe 7 is attached to the rear part of the base 1a.

The pump 3 has its suction side connected to the adhesive tank 2 via a conduit 4 and its discharge side connected to a discharge pipe 7 via a conduit 6 and a bifurcated branch pipe 6 ' The adhesive sucked from the tank 2 is pressure-fed to the discharge pipe 7. As shown in FIGS. 3 and 4, the discharge pipe 7 has a large number of discharge nozzles 7a on the side facing the floor surface.
Are provided in rows along the longitudinal direction. The compressed air tank 5 is connected to the discharge side of the pump 3 via a conduit 8, and compressed air is press-fitted into the discharge side of the pump 3.
The compressed air is pressed into the discharge pipe 7 while reducing the apparent viscosity of the adhesive discharged from the pump 3.

Therefore, the discharge nozzle 7 of the discharge pipe 7
The adhesive is smoothly discharged from a, and a plurality of beads are applied to the floor surface. In such a discharge application operation, the amount of compressed air supplied from the compressed air tank 5 to the discharge side of the pump 3 is adjusted by the air regulator 5a. An air gun 5b is also provided for removing adhering dust.

[0009] The above-mentioned application work to be applied to the floor surface may be performed by continuously pulling the adhesive from the discharge nozzle 7a of the discharge pipe 7 and pulling the handle 1d to advance it in the traveling direction indicated by the arrow. The automatic adhesive applicator having the above-mentioned configuration can easily and smoothly apply a high-viscosity adhesive from a plurality of discharge nozzles and automatically apply it to the floor surface with a simple mechanical operation at hand. Without fatigue
Moreover, the finish is even and the time is shortened.

[0010]

As described above, according to the present invention, since the discharge side of the pump for sucking and feeding the adhesive from the adhesive tank is connected to the discharge pipe together with the compressed air tank, a plurality of discharges provided on the discharge pipe are connected. The high-viscosity adhesive can be smoothly discharged from the nozzle into a plurality of beads to enable automatic application. As a result, the workability of applying the high-viscosity adhesive can be improved.
