Description

[Detailed explanation of the invention] (Industrial application field) This invention relates to a cartridge type painting gun, and its purpose is to supply the paint to the painting gun in the form of a cartridge, and to apply the paint filled in the cartridge to a specific coating. It can be applied to the target object using a tool, and can be applied continuously and at a constant pressure even in difficult-to-reach areas such as high places, narrow spaces, etc., where it is difficult to reach or where painting is difficult. To provide a cartridge type painting gun capable of painting.

(Prior Art) Conventionally, painting guns have been used to carry paint using the jetting force of compressed fluid and spray the paint onto objects to be painted. The paint was sprayed by suctioning the paint from a separately provided paint container using the suction effect of force.

(Problem to be solved by the invention) However, when putting paint into the paint container or moving the container, or during painting work, paint may spill around the building, staining the floor surface of the building and the workers. Ta.

Moreover, although such a painting gun can be suitably used industrially, it is too large to be used as a simple industrial painting tool for household use, and therefore it is not something that is frequently used at home. Nakatsuta.

When performing painting or repair work on the exterior walls of a home, it is used in places where it is difficult to secure a foothold manually, such as on the exterior walls of the upper floors, or where it is difficult to work because the space that requires painting is extremely narrow. No suitable equipment existed to do so.

(Means for Solving the Problems) This invention aims to solve these conventional problems by storing the paint in a cartridge in advance, so that it can be used in places that are difficult to paint with a paint can, such as in high places. We have created a painting gun that can be used for painting easily, with less loss of paint, and less dirt caused by paint from the operator, and a pressing member that is operated only by the pressure of the compressed fluid or by manual force. 6, a cartridge 1 loaded into the paint gun 5 and pressed by the pressing member 6 to eject the internal paint, and a paint tool 11 connected to the injection port 3 of the cartridge 1 . A liquid passage 17 communicating with the injection port 3 is provided inside the base 12 of the coating tool 11 to allow the paint from the cartridge 1 to flow, and this paint is applied to the application section 14 of the coating tool 11 . This relates to a cartridge type painting gun which is supplied by pressure through a narrow passage 18 provided in the base 12 .

(Operation) The pressing member is actuated by the pressure of the squeezing fluid or manual force, and the cartridge loaded in the coating gun is pressed.

Paint is ejected from the jet nozzle of the pressed cartridge, and this paint flows through a passageway in the paint tool connected to the jet nozzle of the cartridge, and then through a narrow passage provided at the base of the paint tool. It is extruded and supplied to the application section.

(Example) Hereinafter, an example of a cartridge type painting gun according to the invention will be described based on the drawings.

In FIG. 1, reference numeral 1 denotes a cartridge filled with paint, and the bottom plate 2 of this cartridge 1 pushes out the paint in the direction of the injection port 3 by a pressing force from the bottom.

Preferably, the tip 4 of the cartridge 1 is sealed before use, and the injection port 3 is formed by detaching the tip 4 during use.

In FIG. 2, reference numeral 5 denotes a painting gun, and inside the painting gun 5 is installed a pressing member 6 such as an air cylinder, a hydraulic cylinder, etc., which is operated by compressed fluid.

As means for applying pressure to this pressing member 6,
A mechanism for pressing by mechanically transmitting manual force may be adopted instead of using a squeezing fluid.

The rod 7 of the pressing member 6 pushes the bottom plate 2 of the cartridge 1 and pushes out the paint contained therein from the injection port 3.

Note that 8 is a hand switch for operating a valve 9, and this valve 9 controls the operation of the pressing member 6 by opening and closing a fluid passage 10 for compressed air, compressed oil, or the like.

FIG. 3 shows an overall view of the cartridge type painting gun according to this invention, in which 11 is a painting tool, and the painting tool 11 is inserted into the injection port 3 of the cartridge 1 .
The attachment port 13 of the base 12 of the base 12 is joined.

As shown in FIG. 3B, the inside of the mounting port 13 communicates with a liquid passage 17, which will be described later, and is formed in an inwardly tapered shape toward the tip with an inner diameter approximately equal to the outer diameter of the injection port 3. There is.

Near the rear end of the joint between the injection port 3 and the mounting port 13, a groove 13a is formed on the inner periphery of the mounting port 13, and the injection port 3 requires a protrusion 3a that fits into the groove 13a. A number of pieces are formed.

The coating tool 11 consists of a base 12 and an applicator 14 such as a sponge, flocked hair, cloth, etc. provided at the tip of the base 12 .

The base 12 consists of a base 15 and a handle 16,
A liquid passageway 17 is formed within this base portion 12 .

When the base 12 is made of a hollow member in advance, this liquid passage 17 may be used as a liquid passage, and when the base 12 is made of a solid member, the hollow part may be used as a liquid passage. The liquid passage 17 may be formed by penetrating the base portion 12 from its tip to its terminal end (the point of contact with the application portion 14).

The liquid passage 17 and the application section 14 are connected to each other via a narrow passage 18 .

The narrow passage 18 is provided with a small diameter at a location close to the liquid passage 17, that is, a location where the paint discharge pressure is high, and a large diameter at a location where the discharge pressure is low, that is, a location far from the liquid passage 17. It is desirable that the amount of paint supplied to the applicator 14 be made uniform to each part of the applicator 14.

Further, a valve 19 for opening and closing the flow of the liquid passage 17 is installed at an arbitrary location on the handle part 16 of the paint tool 11 , and a switch 20 of this valve 19 is attached to the handle part 16, so that the paint flow is controlled by the switch 20. Can be controlled by operation. (See FIGS. 4A, B and 5A, B, C) In this invention, the valve 19 and switch 20 do not necessarily need to be installed.

In the cartridge type painting gun according to the invention, which has such a configuration, first, the cartridge 1 is inserted into the painting gun 5 , the tip 4 of the cartridge 1 is removed, and the installation port of the painting tool 11 is inserted into the injection port 3 of the cartridge 1 . 13 may be directly fitted, or in some cases may be connected for communication via a connecting device such as a hose of a required length.

In this state, a compressed fluid generating device such as an air compressor (not shown) is operated, and the compressed fluid is fed into the pressing member 6 via the pipe 10 and the valve 9.

When the hand switch 8 is activated and the rod 7 of the pressing member 6 is extended, the rod 7 pushes up the bottom plate 2 of the cartridge 1 , and the paint filled in the cartridge 1 is ejected from the injection port 3 to the installation of the paint tool 11 . The liquid is fed into the liquid passageway 17 through the port 13 .

When painting, please use the valve 19 and switch 20.
is attached, operate the switch 20 on the handle portion 16 to keep the valve 19 open.

The coating material is impregnated into the coating portion 14 through the liquid passage 17 and the narrow passage 18 .

In this state, apply the application part 14 to the area that requires application.
If they are brought into contact, painting work can be performed.

In addition, when interrupting or finishing the painting operation, close the valve 19 by operating the switch 20 to stop the flow of paint, and then close the valve 9 by operating the hand switch 8 to add the cartridge 1 . Stop pressure.

(Effects of the invention) As described above, the cartridge-type painting gun according to this invention has a cartridge attached to the painting gun and a specific painting tool attached to the injection port of this cartridge, so that it is possible to use separately prepared paint. It solves the problem of paint spilling from the container in conventional painting work, and also applies paint with constant pressure even in difficult-to-reach places such as high places and narrow spaces. Moreover, this cartridge type painting gun has the effect that it can be suitably used as a painting device for home use or simple industrial use by simply inserting and replacing a cartridge in the device with a simple configuration.
