is connected, and a mixture of oil and gas is produced by a well-known mixing device M (not shown) for liquid and gas using a Venturi tube, or a flow rate control valve (
(not shown).

The porous material of the outer cylinder (9) may be made of any material other than sponge or felt as long as it allows the mixture of liquid, etc. and gas to evenly distribute and leak out to the outside.

The operating state of this oil application device is such that when the strip plate (2) is fed as the press machine is operated, a mixture of oil and air is supplied to the device from the mixing device in conjunction with this movement. The mixture is applied to each axial tube (5) of each coating roll (5) provided above and below.
When the temporary storage chamber (3) of the mixture in the inner cylinder Llj is filled and reaches a constant pressure, the mixture is formed almost evenly in the local part of the inner cylinder t1+. Through hole 14
) to reach the outer cylinder (9). The entire outer cylinder (9) is made of a spongy porous material.

Therefore, the mixture air is evenly dispersed in each pore, and the oil leaks out evenly from the local part of the outer cylinder (9). Then, this outer cylinder +91 rri strip plate (2) is sandwiched from above and below and rotates as the h1 strip plate (2) is fed.
It is applied uniformly to both the upper and lower surfaces of the strip plate (2) at the same time.

In the above embodiment, in order to apply the coating to both the upper and lower surfaces of the strip plate (2) at the same time, the applicator rolls (3) are disposed from top to bottom, or if the application is to be applied only to the bottom surface, the applicator rolls (3) are disposed vertically. A)
A normal roll may be provided on the upper side of the lower side π, and the coating may be applied through the strip in the same manner as described above. Thick strip plate (
2) If the length is short, the applicator roll (5) may be moved instead of the strip plate (2).

Furthermore, it is preferable to insert the shaft tube (5) from both sides (inner cylinder Ll), but it is also possible to insert it from only one side.The liquid to be applied is not limited to oil, but may also include chemicals, water, liquids in a pond, or other liquids. It may also be a mixture of liquid and gas.

Next, as shown in FIGS. 3 and 4, the present invention is applied to an apparatus for applying paint to a wall surface and π wax to a roughened floor surface, for example. There is only one coating roll (A).

That is, the +1) inner cylinder forms a temporary storage chamber (3) for the mixture as described later, and has a thickness of 0T, and the local π is )1 uniform π.
A large number of small through holes (4) are formed. (5) is an axial tube with a large number of holes (5a) formed locally, and the inner tube [+1] is inserted with one side, and the tip (5b) and base (5C) are inserted into the inner tube (1) on both sides. From the side plate (1a) π of the cylinder (1)
is a rotatable π support on the same side of the shaft tube (5). (8
) is a sealing material that is interposed between the shaft tube t51 and the side plate (la) without interfering with the rotation of the cylinder (1), and forms a temporary storage chamber (3) for the mixture in the cylinder (1). be. T! 11
: In the outer cylinder, a porous material such as sponge or felt is wrapped around the outer periphery of the inner cylinder (1), and mixed with air from the small through hole (4) of the inner cylinder (+). The paint or wax should be evenly distributed so that it oozes out evenly from the local area.

(29) is a mixture supply pipe, which is formed of a hard material and communicates with the shaft pipe (5), the base part (5c), and the connecting part (30), and is connected to the dragon side of the supply pipe (29). is an applicator roll (A
) is provided with a grip part (31) for manual operation to press the product against the wall (2), floor, etc. of the object to be coated. The outer cylinder (9) is replaceable, and (32) is a nut for attaching the H side plate. From W (3I), it is connected via a flexible pipe to a known mixing device for liquid and gas using a Venturi tube and a flow rate control valve (chair h is not shown), as in the previous embodiment. be. (33) is a shielding plate.

The operating state of this paint applicator is that when a mixture of paint and air is sent from the mixing device to the device via the supply pipe (29), it flows from the hole (5a) of the shaft pipe (5) into the inner cylinder Ll). Inflow. Fill the temporary storage chamber (3) of the mixture in the inner cylinder (+j) with the mixture. When a constant pressure is reached, the mixture is
) The local π is formed almost uniformly and passes through each small through hole (4) to the outer cylinder t! It reaches 111. Since the outer cylinder (9) is made entirely of a sponge-like multi-porous material, the mixture of alpine paint, wax and air is evenly dispersed in each pore, while the oil is distributed only locally in the outer cylinder (9). It oozes out evenly. Therefore, grip part (
31) and move your hand while bringing the outer cylinder (9) into contact with the wall (2), floor, etc., the outer cylinder (9) will rotate around the shaft tube (5), and as described above, the outer cylinder (9) will rotate around the shaft tube (5). Remove the paint or wax that is constantly and evenly protruding from the entire circumference of the tube (9) to the wall surface (2).
) and floors, etc., evenly.

In the above embodiment, the shaft tube (5) is connected to the inner tube from one side.
It is better to insert it from either side or from both sides. The same applies to the liquid to be applied, not only paint or wax, but also solvents, chemicals, other liquids, sludge, or mixtures of such liquids and gases.

Therefore, the method and apparatus for applying liquid etc. of the present invention have the following effects compared to the conventional methods.

That is, (a) conventional coating methods for plate-shaped objects, which involve dropping liquid with a sponge or roll, can only apply unevenly and insufficiently, or cannot coat both sides at the same time; It was dangerous for workers to inhale the H6 when applying harmful chemicals because it was scattered by the spray kit and applied to unnecessary areas. Furthermore, those that pass through a liquid tank tend to have too much liquid attached to them, are difficult to coat on just one side, and those that are volatile are harmful or uneconomical. For kneading, the liquid applicator of the present invention pumps liquids such as oils and chemicals together with gas and constantly protrudes from a sponge-like multi-porous outer cylinder to coat the entire plate-like object. It can be applied evenly and with sufficient consistency. Moreover, since it does not scatter and can be applied in the minimum required amount without being too thick, it is not only economical, but also eliminates danger, especially when volatile or harmful chemicals are used. Furthermore, if the coating roll is made of one piece of wood, it can be applied to only one side, or if it is made of two pieces of wood, it can be applied to both sides at the same time.

Also, among the conventional methods of applying paint, wax, etc. to walls, floors, etc., methods that use bald or sponge rolls are difficult to apply. etc., and it is difficult to do heavy work on large areas or ceiling surfaces. If a broken spray is used, π can only be applied to a thin film, is uneconomical because it scatters, or is harmful to workers when inhaled.

On the other hand, the liquid applicator of the present invention sends a liquid such as paint, wax, or solvent together with gas, distributes it evenly around the spongy, porous outer periphery, and continuously oozes out the liquid. Therefore, there is no need to apply paint or wax to containers over and over again, and it can be applied continuously even over a wide area.

The application work on the ceiling surface becomes extremely easy without the matapaint wax etc. falling off the surface. Furthermore, when applied, it is possible to obtain a thick film, and it is economical because there is no scattering of paint or wax, and there is no danger of workers inhaling mist and harming their health. This has beneficial effects such as eliminating the need for
