Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a coating nozzle used in a device for uniformly coating a wide surface such as a floor with a viscous liquid.

In this specification, the viscous liquid particularly refers to a viscous material such as an adhesive, paint, or wax that is applied to the floor surface or the like.

[Prior Art] Of the conventional methods that have been performed to uniformly apply viscous liquid to a floor surface, the simplest method is that one operator holds a container of viscous liquid aside and It moves while pouring out an appropriate amount of viscous liquid toward the floor surface from the hole made in the upper surface of. On the other hand, the other worker holds the comb iron in the posture of crawling on the floor surface and uses it to apply the viscous liquid evenly to the floor while stroking the floor surface. It is a method of going.

The comb iron used in this method corresponds to the prior art in the subject of the present invention, and the lower end surface of the iron is provided with the comb at appropriate intervals, and the operator By gripping the handle with your hand and stroking it on the floor, you can draw the traces of the viscous liquid that have passed through the combs on the floor.

[Problems to be Solved by the Invention] Such a conventional apparatus or conventional method is a very primitive one, and the operator is forced to keep an unreasonable posture during the operation, resulting in great fatigue. Also, it is unavoidable that your hands get dirty with viscous liquid, and if the viscous liquid is aqueous, you can wash it immediately with water, but in any case, it is often avoided and avoided as a dirty work. There was a problem such as

As a conventional technique of a viscous liquid coating device for a floor or the like, for example, Japanese Utility Model Publication No. 42-8137 or Japanese Utility Model Application No. 60-
Although there is one disclosed in Japanese Patent No. 39416, all of these problems are to be solved by the present invention, that is, the application work by pushing and pulling back the operating rod is easily and easily performed while maintaining the homogeneity of the viscous liquid. It does not lead to the task of doing.

The present invention has been made in view of such conventional problems. 1) Only one worker can perform the work of uniformly applying a viscous liquid onto a wide flat surface. As with an electric vacuum cleaner, you can easily carry it from beginning to end while holding the operating rod with the tip of the coating nozzle in your hand and moving it on a flat surface in an upright position. 2) Moving the coating nozzle The width of the area to be applied is expanded by one stroke, the wasteful consumption of the viscous liquid is reduced, and the application in that area is performed very uniformly. 3) When the application nozzle is moved, Or when performing the coating work by pushing forward and pulling back in the same direction, even if the coating nozzle tilts with the operating rod, or alternately repeats tilting in the opposite direction, The tip is always Since the tip of the comb-shaped nozzle does not float up from the flat surface and the viscous liquid is excessively applied because it is in contact with the flat surface with an appropriate pressing force, 4) the movement of the coating nozzle on the flat surface It is easy and light, and the uniformity of coating over the entire length of the nozzle is always maintained in response to the operation of the nozzle. 5) The movement of the coating nozzle is exactly the same in both forward and backward directions. It is an object of the present invention to provide a viscous liquid coating nozzle capable of achieving the same effect.

[Means for Solving the Problems] In order to achieve the above object, in the viscous liquid coating nozzle of the present invention, the constitution of the coating nozzle used in the device for uniformly coating the viscous liquid on a wide plane. As one, a laterally long cylindrical chamber for accommodating the viscous liquid therein is provided, and an inflow port for inflowing the viscous liquid from the outside toward the cylindrical chamber is provided at approximately the center of the upper surface thereof. A nozzle main body having a large number of holes for allowing the viscous liquid in the chamber to flow out downwardly evenly on its bottom surface, and is provided below the bottom surface of the nozzle main body and adjacent to the bottom surface, A pair of front and rear comb-shaped nozzles disposed on the side of both side surfaces that are long in the horizontal direction of the nozzle body, a pair of cover plates disposed on the side of the left and right sides, and the end portions of each of them. The circumference is surrounded by a rubber plate that is placed to close the gap. And a roller for moving the nozzles provided rotatably below both ends of the nozzle body.The pair of comb-shaped nozzles both move up and down along the laterally long side surfaces. It is provided so that the lower end of the comb nozzle and the above-mentioned plane can be provided with a comb for forming a streak of viscous liquid on the plane when the lower end is in contact with the above-mentioned plane. The comb nozzle is provided with pressing means for keeping the pressing force between them according to the vertical movement of the comb nozzle to prevent excessive outflow of the viscous liquid.

[Operation] With the viscous liquid coating nozzle of the present invention, in order to coat the viscous liquid evenly on a wide flat surface, especially on the floor surface, the worker wears the rod mounted on the tip of the operating rod. The viscous liquid is delivered to the nozzle by, for example, a positive displacement pump prepared for delivering the viscous liquid.

In this state, the operator operates the operating rod or the like to move the application nozzle along the plane in the same manner as an electric vacuum cleaner, thereby applying viscous liquid.

The viscous liquid sent from the pump to the coating nozzle enters a horizontally long cylindrical chamber inside the nozzle body from an inlet located almost in the center of the upper surface of the coating nozzle, fills the chamber, and at the same time the nozzle body is filled. It is made to flow out evenly toward the space formed below from a large number of holes formed in the bottom surface of the.

The viscous liquid flowing into the lower space via the above flow path is surrounded by a comb nozzle surrounding the space, lid plates on both left and right side surfaces, and a rubber plate that closes the gaps at each end thereof. The viscous liquid stored in the space is
Not only is it placed in a highly accurate and homogeneous state in every corner, but when this is taken out from the comb plate for application, the flow of viscous liquid to replenish it is the same as that of the first-stage chamber. Inflow from one inflow port at the center of the upper part,
For the second stage, since the inflowing liquid is allowed to flow evenly down, it passes through a large number of holes and flows into the lower space, so that it acts to enhance the homogeneity of the liquid. The homogeneity of the liquid taken out for coating through the comb plate is constant over the entire length of the nozzle and is always realized in response to the operation of the nozzle.

When the coating nozzle is moved along the floor surface, the viscous liquid accumulated in the space below, from the comb nozzles before and after partitioning the space, from the comb of the comb nozzle located on the side of the moving direction, It becomes a streak of viscous liquid and flows out onto the floor.
At this time, the coating nozzle usually inclines to some extent in the direction of movement, but since the comb nozzle is provided so as to be vertically movable along the outer surface of the nozzle body, the tip of the comb nozzle is Does not float up from the floor and the viscous liquid is not applied excessively.

Further, the movement of the coating nozzle on the floor surface is freely and smoothly performed by the roller below the nozzle body.

EXAMPLES Examples will be described with reference to the drawings. FIG. 1 shows an example of an entire apparatus for applying a viscous liquid to a floor surface using the viscous liquid application nozzle of the present invention.
