Description

[Detailed description of the device]

[0001]

[Technical field to which the device belongs]

 The present invention relates to a gravity-type paint cup that is connected to a suction port of a spray coating machine and gravity feeds paint to the spray coating machine.

[0002]

[Prior art]

 Such a paint cup is Japanese Utility Model Laid-Open No. 61-139772 proposed by the inventor of the present applicant. The top of this paint cup is fitted with a vent lid with a vent, the open top of the cup is closed to allow ventilation, and the bottom of the bottom is connected to the paint inlet of a spray painting machine to remove the paint in the cup. An L-shaped connecting cylinder that supplies the spray coating machine is integrally provided.

[0003]

[Problems to be solved by the device]

 When this paint cup is attached to a spray painting machine and painting is done, and when painting is finished and paint remains in the cup, the paint cup itself does not become a storage container for paint, so remove the supply cylinder from the spray painting machine, The ventilation lid must be opened and the paint in the cup must be transferred to the container for cleaning, which is very troublesome. Further, depending on the direction of the spray coater during painting, the paint in the cup may leak out from the vent hole of the vent lid and stain the surrounding area. For this reason, in the paint cup, a cylindrical weir wall is provided around the ventilation hole of the ventilation lid to prevent the paint that has leaked outside from spreading to the surroundings, but if there is a large amount of leakage, it will overflow from the weir wall. Shed.

[0005]

[Embodiment of device]

 In the illustrated embodiment, reference numeral 10 denotes a cylindrical cup body having a bottom 10 'which is concavely spherically shaped, and a paint outlet cylinder 11 projects downwardly from the center of the bottom and has a diameter of the body at the upper end. The upward cylinder 12, which is slightly smaller than the above, projects shortly. As an example, the dimensions of the cup body are about 75 mm in diameter and about 110 mm in height, and male threads are provided on the outer circumference of the outflow tube 11 and the upward tube 12.

Reference numeral 13 denotes a ventilation lid having a ventilation hole 14 having a diameter of about 1 mm in the center of the upper wall, and 15 a sealing lid having no ventilation hole in the upper wall, both of which are inner circumferences of the cylindrical walls 13 ′ and 15 ′. It can be mounted by covering the upward cylinder 12 of the cup main body from above with the female screw and screwing.

Reference numeral 16 is a sealing cap that is screwed into the paint outflow tube 11 to be attached to close the outflow tube, 17 is an L-shaped supply tube, and a tube portion 18 into which the upper end is screwed into the outflow tube 11 is attached. It is composed of a connecting cylinder portion 19 projecting laterally from the lower end of the portion 18, and the inside of the cylinder portion 18 and the inside of the connecting cylinder portion 19 communicate with each other to form an L-shaped paint outlet hole 17 '. The connecting cylinder portion 19 rotatably holds a cap nut 20 having a knob at its tip. As is known, by inserting the tip of the connecting cylinder part 19 into the suction port 32 of the paint suction cylinder 31 on the side of the spray coating machine 30 and screwing the cap nut 20 into the male screw on the outer circumference of the paint suction cylinder. The supply cylinder 17 can be attached to the side of the spray coating machine (Fig. 1B, Fig. 2).

The cup body is polypropylene, the ventilation lid, the sealing lid and the sealing cap are polypropylene, the tube portion of the supply cylinder is a molded product of nylon or Duracon, and the connecting cylinder is the metal connecting cylinder part into which the cap nut 20 is fitted. The rear part is inserted into the molding die of the tubular part and molded by insert molding.

To perform painting, as shown in FIGS. 2 and 3, a connecting tube 17 is attached to the paint outflow tube 11 of the cup body, and the connecting tube portion 19 of the supply tube is fixed by the cap nut 20 as described above. It is attached to the suction cylinder 31 of the spray coating machine 30, paint is put inside the cup body, and the upper surface of the cup body is closed with the ventilation lid 13. The ventilation lid has a ventilation hole 14, and the interior of the cup body communicates with the outside air through the ventilation hole, so that the paint in the cup body flows into the suction port of the spray coating machine by gravity. This allows the paint to be sprayed from the spray coating machine with compressed air for coating.

After the painting is completed, the ventilation lid is removed and the sealing lid 15 is attached to close the upper surface of the cup body. Then, the cap nut 20 is loosened, and the connecting cylinder portion 19 of the supply cylinder 17 is removed from the suction cylinder of the spray coating machine. Since the upper surface of the cup body is sealed by the sealing lid, the paint does not flow out from the connecting tube portion 19. Next, the supply cylinder 17 is removed from the outflow cylinder 11, and the sealing cap 16 is attached to the outflow cylinder to close it. Even if the supply cylinder 17 is removed from the outflow cylinder 11, the paint does not flow out from the outflow cylinder because the upper surface of the cup body is closed by the sealing lid. In this way, the paint remaining in the cup body can be preserved.

During coating, the spray coating machine sprays the coating in various directions such as diagonally upward and diagonally downward, and with this, the cup body also tilts in various directions. In this case, when the cup body tilts and a part of the paint in the main body enters the ventilation lid, it leaks out from the ventilation hole. In order to prevent this, the funnel-shaped paint leak has a downward conical surface 22 having a small hole 23 in the center, and a small-diameter cylindrical portion 24 protruding downward from the center of the conical surface and communicating with the small hole 23. The preventive tool 21 is fitted inside the ventilation lid 12, and the upper surface of the cup body is closed with the ventilation lid. If necessary, a flange 25 may be provided on the outer circumference of the upper end of the conical surface 22 to contact the upper end of the cup body. The diameter of the small hole 23 at the center of the conical surface and the inner diameter of the small-diameter cylindrical portion 24 are about 1 mm, and the paint leakage prevention tool is made of, for example, soft polyethylene.

When the paint leakage prevention tool 21 is fitted inside the ventilation lid 13 to close the upper surface of the cup body, as shown in FIG. 3, the inside of the cup body has the ventilation hole 14 of the ventilation lid and the paint. Since it communicates with the outside air through the small hole 23 and the small-diameter cylindrical portion 24 of the leak preventer, the paint in the main body flows into the suction port of the spray coating machine by gravity, and at the same time the cup main body tilts during the coating process. However, the paint in the main body cannot enter the space between the ventilation lid and the conical surface unless it passes through the small-diameter cylindrical portion 24 and the small hole 23 of the conical surface. Even if the cup body is tilted, the paint does not flow into the inner circumference of the small-diameter cylindrical portion, and it is possible to completely prevent the paint from leaking out from the ventilation hole of the ventilation lid (Fig. 4).

[0013]

[Effect of device]

 According to the first aspect, since the cup body serves as a storage container for the paint, it is possible to eliminate the trouble of transferring the paint remaining in the cup body to the storage container or washing the paint. According to the second aspect, it is possible to prevent the paint from leaking to the outside from the ventilation hole of the ventilation cover during the coating and to stain the surroundings.
