Description

[Detailed description of the invention] (Field of industrial application) This invention relates to a paint supply type roller that automatically supplies paint to the application roller while painting.The purpose of this invention is to prevent paint leakage when painting is interrupted, and also to finish painting. To provide a paint supply type roller capable of smoothly discharging residual paint in an application roller.

(Prior art and its problems) Conventionally, as a paint supply type applicator that performs painting while automatically supplying paint, Japanese Utility Model Application Publication No. 49-7152 and Japanese Utility Model Application No. 49-7152,
No. 54-106260 each have previously disclosed devices.

As shown in Fig. 3A and B, both devices supply paint to the bristle strands d from the paint flow passage b in the handle a through the paint outflow hole c, and by opening and closing the on-off valve e at the base of the handle a. Paint can be supplied and interrupted, but since the paint outflow hole c does not have a means to automatically stop the outflow of paint, even if the on-off valve e is closed at the time of interruption of painting, the paint in the paint flow path b will not be filled with paint. There was a risk that it would naturally flow out of the outflow hole and pollute the surrounding area.

In addition, the paint outflow hole c formed at the root of the hair bundle d
Since there is no other means for discharging the paint in the paint flow path b, even if the paint supply is stopped and the on-off valve e is opened after painting is completed, the paint remaining in the paint flow path b will be absorbed by the resistance of the hair bundle d. Due to this, smooth ejection was not possible.

(Means for solving the problem) In this invention, the base of the paint distribution pipe is covered with a handle, and the coating roller is pivotally supported at the tip of the paint distribution pipe. In the paint supply type roller, which is communicated with the paint distribution pipe through the paint supply hole on the circumferential surface of the tip part, and the internal space of this application roller is opened to the outside world through the paint outflow hole on the circumferential surface of the roller, A connection part is formed at the base of the paint distribution pipe to detachably connect the tip of the paint supply hose, and the handle is provided with an opening/closing valve for opening and closing the inside of the paint distribution pipe, and protrudes from the side wall of the roller. A paint discharge port at the tip of the paint distribution pipe can be opened and closed by a discharge valve, and a piston valve is slidably inserted into the paint distribution hole, and the inner space side end of the piston valve is a valve with an expanded diameter. All of the above problems are solved by providing a paint supply type roller with a head.

(Example) An embodiment of this invention will be described based on the drawings.

FIGS. 1 and 2 are diagrams illustrating a paint supply type roller according to an embodiment of the present invention, and numeral 1 in the figures indicates the paint supply type roller.

In this paint supply type roller 1, a handle 3 is mounted on the base of a paint distribution pipe 2, and an application roller 4 is pivotally supported at the tip of this paint distribution pipe 2.

The internal space 5 of the applicator roller 4 is communicated with the paint flow passage 7 in the paint distribution pipe 2 via the paint supply hole 6 on the circumferential surface of the tip of the paint distribution pipe 2, and the internal space 5 of the applicator roller 4 is Roller circumferential surface 4
It is opened to the outside world through a paint outflow hole 8.

A connecting portion 10 is formed at the base of the paint distribution pipe 2 to detachably connect the tip of the paint supply hose 9.

An on-off valve 11 for opening and closing the paint flow path 7 is disposed on the handle 3.

A discharge valve 13 for opening and closing a paint discharge port 12 at the distal end of the protrusion is disposed at a protruding end portion of the paint distribution pipe 2 protruding from the side wall of the coating roller 4.

A piston valve 14 is slidably inserted into the paint outlet hole 8, and the end of the piston valve 14 on the inner space 5 side forms a valve head 15 having an enlarged diameter.

Paint supply type roller 1 according to an embodiment of this invention
is configured as described above, and its usage will be explained next.

To perform painting work, as shown in FIG. 2, the paint supply type roller 1 is connected to the tip of the paint supply hose 9, which extends from the paint can 16 via the pump 17, through the connection part 10, and is opened and closed. Open valve 11,
And with the discharge valve 13 closed, the pump 17
While operating the application roller 4, the coating surface 18 is
It is preferable to roll the paint in the paint can 16 sequentially through the paint supply hose 9, the paint distribution pipe 2, and the paint supply hole 6, and then into the internal space 5 of the application roller 4.
On the other hand, the piston valve 14 slides toward the inner space 5 by contact with the painted surface 18, and the valve head 15 opens the paint outlet hole 8, so that the inner space 5
The paint inside will automatically flow out from the paint outflow hole 8.

To interrupt the painting operation, use paint supply roller 1.
All you have to do is lift up the coating roller 4 and separate it from the coating surface 18, and the pressure of the coating will release the piston valve 14.
slides toward the outside world, the paint outflow hole 8 is automatically closed by the valve head 15, and the outflow of paint is stopped.

To finish the painting work, first close the on-off valve 11 while lifting the paint supply roller 1, then stop the pump 17 and close the paint supply hose 9.
All you have to do is remove the paint supply roller 1 from the coating roller 4, and the paint will remain under pressure inside the applicator roller 4.
The paint outflow hole 8 is closed by the valve head 15 to prevent paint from flowing out.

In order to discharge the paint remaining in the coating roller 4 in such a state, it is sufficient to open the discharge valve 13 and then open the on-off valve 11, and the base of the paint outflow pipe 2 becomes an air vent and the paint discharge hole is opened. 1
Paint is smoothly discharged from 2.

(Effects) In this invention, a handle is mounted on the base of the paint distribution pipe, and an applicator roller is pivotally supported at the tip of the paint distribution pipe. In a paint supply type roller that is communicated with the paint distribution pipe through a supply hole and whose internal space is open to the outside world through a paint outflow hole on the peripheral surface of the roller, the base of the paint distribution pipe is A connecting portion is formed to detachably connect the tip of the paint supply hose, and the handle is provided with an on-off valve for opening and closing the inside of the paint distribution pipe, and the tip of the paint distribution pipe protrudes from the side wall of the roller. The paint discharge port of the paint can be opened and closed by a discharge valve, a piston valve is slidably inserted into the paint flow hole, and the end of the piston valve on the inner space side is a valve head with an expanded diameter. Since it is a supply type roller, it has the following effects.

In other words, the valve head automatically opens and closes the paint outlet hole simply by bringing the circumferential surface of the applicator roller into contact with the painted surface or by separating the circumferential surface of the applicator roller from the painted surface.
Painting work can be interrupted without paint leaking, and there is no risk of contaminating the surrounding area.

In addition, by simply closing both the discharge valve and the opening/closing valve, the paint remains under pressure inside the applicator roller, and this pressurizing force causes the valve head to close the paint outflow hole, preventing paint from leaking. By simply removing the paint supply roller from the paint supply pipe and opening both the discharge valve and the open/close valve, the base of the paint distribution pipe is used as an air vent to smoothly discharge the residual paint in the application roller from the discharge port. Cleaning after painting work can be done efficiently without polluting the surrounding area.
