- the liquid paint is charged and atomized by being subjected to centrifugal force as described in Japanese Patent No. 4274894, and jumps out as a liquid thread from the peripheral portion of the bell cup.
- the flying liquid paint is applied to the body by electrostatic action or the like based on the potential difference. Thereby, electrostatic coating is performed.
- the rotation speed of the bell cup is set so that the liquid paint can be scattered as a liquid thread from the peripheral edge of the bell cup.
- the appropriate number of revolutions varies depending on the required degree of atomization of the liquid paint, and is, for example, about 50000 rpm for a large one and about 10,000 rpm for a small one.
- the centrifugal force received by the liquid paint increases as the rotation speed of the bell cup increases.
- the liquid paint receives a large centrifugal force, it spreads over a wide range in the process of starting from the peripheral edge of the bell cup and reaching the workpiece. That is, the liquid paint adheres to a portion other than the portion to be coated, and the thickness of the coating film decreases at the portion to which the liquid paint adheres. For this reason, it becomes difficult to form a coating film having a desired thickness at a desired site, and it is difficult to improve the coating efficiency.

- the diameter of the bell cup is more preferably 80 to 120 mm.
- the rotation speed of the bell cup can be set to 10,000 to 25000 rpm.
- a bell cup having a large diameter is used. For this reason, when it is going to obtain the droplet diameter substantially equivalent to the droplet diameter when using a small-diameter bell cup, the rotation speed of the bell cup can be reduced. As a result, the centrifugal force acting on the liquid paint that moves along the creeping surface of the bell cup toward the peripheral edge is reduced.
- the droplet diameter when jumping out from the bell cup can be made substantially the same as when the bell cup has a small diameter, the coating film is prevented from being coarse. For this reason, it is easy to make a coating film into desired thickness.
- the plurality of lead-out holes of the hub member for leading the paint to the bell cup have the same shape and the same size and are formed along the circumferential direction.
- a liquid film in which the liquid paint is regularly dispersed is formed along the surface of the bell cup.
- a bell cup having a large diameter of 75 to 150 mm is used. For this reason, even when the rotation speed of the bell cup is reduced, a droplet diameter substantially equal to the droplet diameter when using a small-diameter bell cup can be obtained. For this reason, it is easy to obtain a coating film having a desired thickness.
- FIG. 1 is a side sectional view along the longitudinal direction of a rotary atomizing coating apparatus 10 according to the present embodiment.

- the inner peripheral wall of the insertion hole 27 and the paint supply nozzle 24 are separated from each other, and therefore, a clearance of a predetermined interval is formed between the hub member 26 and the paint supply nozzle 24.
- the hub member 26 is formed with a plurality of discharge holes 30 (outlet holes) for discharging the liquid paint stored in the paint reservoir 28.
- the discharge holes 30 have the same shape and the same dimensions, and the separation distances between the adjacent discharge holes 30, 30 are also equal.

- the second paint diffusing unit 44 is, for example, a curved surface having a predetermined radius of curvature.
- a guide groove (not shown) connected to the second paint diffusion portion 44 is formed in the vicinity of the peripheral edge portion 46.
- the diameter D (see FIG. 1) of the bell cup 20 is set to 75 to 150 mm. If it is less than 75 mm, the bell cup 20 needs to be rotated at a high speed. On the other hand, if it exceeds 150 mm, the bell cup 20 becomes large and difficult to handle.
- a more preferable range of the diameter D of the bell cup 20 is 80 to 120 mm.
- the diameter D is defined as a straight line connecting an arbitrary point on the peripheral edge 46 of the bell cup 20 and another point on the peripheral edge 46 separated by 180 ° with the rotation axis A as the axis of symmetry.

- the air supply passages 56 and 58 communicate with the inner ejection hole 66 and the outer ejection hole 68 through the first chamber 62 and the second chamber 64, respectively. Accordingly, shaping air is ejected from each of the inner ejection hole 66 and the outer ejection hole 68.
- the rotary atomizing coating apparatus 10 is basically configured as described above. Next, the function and effect will be described.
- the robot When performing coating on the workpiece W shown in FIG. 4, the robot performs an appropriate operation so that the rotary atomizing coating apparatus 10 faces the workpiece W. Next, the shaft 16, the hub member 26, and the bell cup 20 are rotated under the action of the air motor, and a negative high voltage is applied to the bell cup 20 by the high voltage generator.
- the liquid paint is discharged from the paint supply nozzle 24 toward the paint reservoir 28 of the hub member 26.
- the liquid paint flows out from the discharge hole 30 of the hub member 26 to the creeping surface 38 of the bell cup 20 and becomes a liquid film by receiving a centrifugal force from the rotating bell cup 20 to form a thin film.
- the bell cup 20 heads to the peripheral edge 46.
- all the discharge holes 30 have the same shape and the same size, and the distance between them is also equal.

- first paint diffusing part 42 and a second paint diffusing part 44 are formed on the creeping surface 38 of the bell cup 20 (see FIG. 3). Since the first paint diffusing portion 42 is a convex curved surface, the centrifugal force acting on the liquid paint passing through the first paint diffusing portion 42 is increased. Accordingly, the moving speed of the liquid paint is increased, which contributes to the thinning of the liquid paint.
- the second paint diffusing portion 44 has a concave curved surface
- a component force in a direction perpendicular to the concave curved surface is generated during the centrifugal force component. growing. Accordingly, the liquid paint is easily guided to the peripheral edge 46. Since a negative high voltage is applied to the bell cup 20, most of the liquid paint is discharged from the discharge hole 30 of the hub member 26 and charged in the process of moving along the creeping surface 38 of the bell cup 20. A part of the liquid paint is charged before being discharged from the discharge hole 30.
- shaping air is supplied from the air supply source.
- a part of the shaping air is ejected from the inner ejection hole 66 through the air supply passage 56 of the flow path forming member 48 and the first chamber 62 of the shaping air ring 50, and another part is flow path forming member. It is ejected from the outer ejection hole 68 through the 48 air supply passages 58 and the second chamber 64 of the shaping air ring 50.
- the liquid paint is ejected from the peripheral edge 46 of the bell cup 20 as liquid yarn by the shaping air ejected from the inner ejection hole 66.
- the shaping air ejected from the outer ejection hole 68 becomes an air curtain, the diffusion range of the liquid yarn is defined.
- the liquid yarn that has jumped out of the bell cup 20 flies toward the workpiece W.
- This work is electrically connected to a ground or the like in advance. For this reason, a potential difference is generated between the liquid paint and the workpiece. Therefore, the liquid paint is attracted to the work by electrostatic action and applied to the work.
- FIG. 6 is a graph showing the droplet diameter when the discharge amount of the liquid paint is changed.
- the droplet diameter when the rotation speed is 25 k (25000) rpm using the bell cup 20 having a diameter of 70 mm is approximately the same as the droplet diameter.
- the rotation speed at which the droplet diameter is equivalent is 13k (13000) rpm. That is, when the 120 mm bell cup 20 is used, the rotation speed can be set to approximately 1 ⁇ 2 of the rotation speed when the 70 mm bell cup 20 is used.
- FIG. 6 also shows changes in droplet diameter when a bell cup 20 having a diameter of 120 mm is used and the rotation speed is the same as that of the bell cup 20 having a diameter of 70 mm. At the same rotational speed, the droplet diameter decreases as the diameter of the bell cup 20 increases. In this case, the centrifugal force acting on the liquid paint is increased, and the liquid paint is sheared.
- FIGS. 7 to 9 show droplet diameters when the first to third liquid paints having different viscosities are used with the bell cup 20 having a diameter of 120 mm or 70 mm and the rotation speed is different. It is a graph which shows the change of measured value. The viscosities of the first to third liquid paints increase in the order of FIG. 7, FIG. 8, and FIG. These FIGS. 7 to 9 also show that when the bell cup 20 having a diameter of 120 mm is used, the rotational speed can be halved when a droplet diameter substantially equal to that of the bell cup 20 having a diameter of 70 mm is obtained. .
- FIG. 4 the flight path of the liquid paint when the rotation speed is set to 25 krpm using a bell cup 20 having a diameter of 70 mm is indicated by a broken line, and the rotation speed is set to 13 krpm using the bell cup 20 having a diameter of 120 mm.
- the flight path of the liquid paint is shown by a solid line. From FIG. 4, it can be seen that in the latter case, the liquid paint diffusion range can be narrowed while making the droplet diameter substantially the same as the former. In the latter, since the rotational speed is small, the centrifugal force acting on the liquid paint is small, and therefore, the force of the bell cup 20 jumping outward in the diameter direction is small.
- FIGS. 10 to 12 are graphs showing changes in coating efficiency when the first to third liquid paints shown in FIGS. 7 to 9 are used and the amount of ejection of shaping air is changed. . Note that the coating efficiency is compared under the condition that the coating width is uniform. That is, it is the coating efficiency when the width at half the maximum thickness of the coating film is the pattern width and the pattern width is 300 mm.
- FIG. 10 compares the coating efficiency when the shaping air is 200 NL / min at ⁇ 70 mm and the coating efficiency when the shaping air is 300 NL / min at ⁇ 120 mm. In this case, an improvement of 6% was observed.
- FIG. 11 shows the coating efficiency when the shaping air is 225 NL / min at ⁇ 70 mm and the coating efficiency when the shaping air is 350 NL / min at ⁇ 120 mm.
- FIG. 12 shows the coating efficiency when the shaping air is 150 NL / min at ⁇ 70 mm and the coating efficiency when the shaping air is 300 NL / min at ⁇ 120 mm. In each, an improvement of 6% and 5% is observed.
- the target droplet diameter can be obtained while reducing the rotation speed of the bell cup 20.
- the diffusion range of the liquid paint during flight can be narrowed. For this reason, the coating material used as the desired particle size can be concentrated on the desired part of the workpiece
- the present invention is not particularly limited to the above-described embodiment, and various modifications can be made without departing from the gist of the present invention.
