Hub 18 may be attached to the tip of hollow shaft 14 or the base end of bell cup 11 so as to rotate with hollow shaft 14 or bell cup 11, or it may be attached to the tip of feed tube 16 so as to be non-rotating.
- Bell cup 11 can also be made of an electrically insulating material.
- the hub 18 is also circular when viewed from the front.
- a plurality of paint discharge holes 19 are formed at a predetermined interval on the outer periphery of the hub 18, and the paint or cleaning thinner supplied from the tip of the feed tube 16 passes through the paint discharge holes 19 of the hub 18 and is guided to the paint diffusion surface 111 of the bell cup 11, where it is dispersed from the entire circumference of the tip edge 113 by centrifugal force.
- shaping air is supplied from the back side of the bell cup 11.
- inner shaping air Sin concentric with the rotation axis CL is blown out in an annular slit shape from the back side of the bell cup 11, and at the same time, outer shaping air Sout , which has a larger diameter than the inner shaping air Sin and is concentric with the rotation axis CL, is blown out in an annular slit shape.
- an air ring 20 is provided at the tip of the housing 12 so as to be concentric with the rotation axis CL and surround the bell cup 11.

- an annular second semi-closed space 26 is formed, and a plurality of through holes 27 are formed at a predetermined interval on the base end side.
- a ring-shaped slit-shaped gap is formed between the tip of the inner ring 22 and the tip edge 113 of the bell cup 11.
- this ring-shaped slit-shaped gap is used as the first air outlet 23 for blowing out the inner shaping air S in .
- a first semi-closed space 25 is formed between the inner peripheral surface of the inner ring 22, the outer surface 112 of the bell cup 11, and the housing 12, and a plurality of through holes 28 are formed at a predetermined interval on the base end side.
- Figure 3 shows the airflow generated in front of the bell cup 11, in the case where no shaping air is supplied at all.
- the bell cup 11 rotates at high speed, the air on the surface of the bell cup 11 is dragged, generating an airflow F1 that flows radially outward.
- airflow F1 is generated, air in front of the bell cup 11 is drawn in the direction of the bell cup 11, generating an airflow F2.
- Fig. 4A shows the state of the air flow generated on the front surface of the bell cup 11, in the case where only the inner shaping air Sin is supplied.
- Fig. 4B shows the case where the air flow rate is increased when only the inner shaping air Sin is supplied.
- the air flow (F1 in Fig. 3) directed radially outward from the bell cup 11 and the inner shaping air Sin join together, generating a circulating air flow F3 between the bell cup 11 and the surface of the workpiece P.
- the cross section of the coating film C has a two-humped camel shape with a concave center.
- Figure 4C is a diagram showing the film thickness distribution when only the inner shaping air S in is supplied as shown in Figures 4A and 4B, with the horizontal axis indicating the position on the surface of the object P and the vertical axis indicating the film thickness of the coating C.
- the film thickness distribution becomes a two-humped camel shape with a concave center as shown in Figure 4C, and although increasing the air flow rate causes the paint particles to gather in the center, the two-humped camel shape with a concave center remains unchanged.
- the width of the coating pattern is about 550 to 600 mm, and no significant fluctuation in the width of the coating pattern due to fluctuations in the air flow rate is observed.
- Fig. 5A shows the state of the air flow generated on the front surface of the bell cup 11, in the case where only the outer shaping air S out is supplied.
- Fig. 5B shows the case where the air flow rate is increased when only the outer shaping air S out is supplied.
- this outer shaping air S out is blown out from the outside of the first air outlet 23 of the inner shaping air S in at an angle that targets the bell edge of the bell cup 11, so a velocity component toward the central axis of the bell cup 11 is generated.
- This outer shaping air S out and the air flow (F1 in Fig.
- the cross section of the coating film C has a two-humped camel shape with a concave center, but compared to the cross section of FIG. 4A, the spacing between the raised portions is slightly smaller.
- Figure 5C is a diagram showing the film thickness distribution when only the outer shaping air S out is supplied as shown in Figures 5A and 5B, with the horizontal axis indicating the position on the surface of the object P and the vertical axis indicating the film thickness of the coating film C.
- the film thickness distribution becomes a two-humped camel shape with a concave center as shown in Figure 5C, and although increasing the air flow rate causes the paint particles to gather in the center, the two-humped camel shape with a concave center remains.
- the width of the coating pattern is about 550 to 600 mm, and it can be seen that while the film thickness at the center varies greatly with the variation in the air flow rate, the width of the coating pattern is not significantly affected.
- Fig. 6A shows the state of the airflow generated at the front of the bell cup 11, and shows the case where both the inner shaping air Sin and the outer shaping air Sout are supplied.
- the airflow (F1 in Fig. 3) directed radially outward from the bell cup 11 joins with the inner shaping air Sin and the outer shaping air Sout , and a circulating airflow F6 is generated between the bell cup 11 and the surface of the workpiece P.
- This circulating airflow F6 allows the circulating airflow F3 by the inner shaping air Sin shown in Fig.
- the paint particles gather appropriately in the center while maintaining the pattern width.
- the outer shaping air S out becomes an excess air flow F4 and diffuses to the surroundings after colliding with the surface of the workpiece P.
- the cross section of the coating film C becomes a trapezoid with the central depression eliminated.
- Fig. 6B is a diagram showing the film thickness distribution when both the inner shaping air S in and the outer shaping air S out are supplied as shown in Fig. 6A (the flow rate of the inner shaping air S in is 145 NL/min, and the flow rate of the outer shaping air S out is 175 NL/min), where the horizontal axis indicates the surface position of the workpiece P, and the vertical axis indicates the film thickness of the coating film C.
- the film thickness distribution when both the inner shaping air S in and the outer shaping air S out are supplied is such that the width of the coating pattern is about 400 mm, and the film thickness distribution of the coating pattern rises sharply toward the center, forming the side of a truncated cone. Also, the film thickness in the central part of the coating pattern becomes almost flat, and the width of the flat part expands to about 250 mm.
- the inner shaping air S in is blown out in an annular slit shape from the back surface of the bell cup 11, and at the same time, the outer shaping air S out is blown out in an annular slit shape, thereby producing a coating pattern in the shape of a truncated cone, in which the film thickness distribution in the direction perpendicular to the direction of movement is trapezoidal.
- the flow rate of the outer shaping air S out is equal to or greater than the flow rate of the inner shaping air S in .
- the outer shaping air S out can shield the mixed gas of the inner shaping air S in and the atomized coating particles so that the front of the bell cup 11 is filled with the outer shaping air S out , resulting in a coating pattern with a film thickness distribution that is steep around the periphery of a truncated cone shape and flat in the center.
- the flow velocity of the outer shaping air S out is equal to or greater than the flow velocity of the inner shaping air S in .
- the ratio of the opening cross-sectional area of the first air outlet 23, which is annular slit-shaped, to the opening cross-sectional area of the second air outlet 24, which is also annular slit-shaped is 3:1 to 4:1.
- the distance between the tip of the inner circumferential surface of the air ring 20 and the tip of the bell cup 11 does not exceed 2 mm.
- the inner shaping air Sin is non-directional with respect to the circumferential direction of the first air outlet 23.
- Non-directional with respect to the circumferential direction of the first air outlet 23 means that the blowing direction of the inner shaping air Sin is not inclined in the circumferential direction, but is blown out along the direction of the rotation axis CL of the bell cup 11.
- FIG. 7A is a diagram showing the film thickness distribution of Comparative Example 1 in which the first air outlet 23 from which the inner shaping air S in is blown out is configured with a plurality of holes instead of a slit shape
- FIG. 7B is a diagram showing the film thickness distribution of Comparative Example 2 in which the second air outlet 24 from which the outer shaping air S out is blown out is configured with a plurality of holes instead of a slit shape.
- the film thickness distribution of the coating film is not symmetrical with respect to the center of the bell cup 11. This is because the holes in Comparative Examples 1 and 2 are formed at an inclination in the circumferential direction, and the shaping air blown out from these holes has a directional property in the circumferential direction.
- the film thickness distribution of the coating film is symmetrical with respect to the center of the bell cup 11, as shown in FIG. 6B.
- Second Embodiment Fig. 2 is a cross-sectional view showing another embodiment of the rotary atomizer coating apparatus according to the present invention.
- the rotary atomizer coating apparatus 1 according to the embodiment shown in Fig. 2 is partially different from the rotary atomizer coating apparatus 1 according to the embodiment shown in Fig. 1 in the configuration of the air ring 20. Since the other configurations are the same as those of the rotary atomizer coating apparatus 1 according to the embodiment shown in Fig. 1, the same components are denoted by the same reference numerals and the description thereof will be incorporated herein.
- the air ring 20 of this embodiment is provided at the tip of the housing 12 so as to be concentric with the rotation axis CL and surround the bell cup 11, similar to the embodiment of the rotary atomizer coating device 1 shown in FIG. 1.
- the air ring 20 of this embodiment is also formed by assembling an outer ring 21 and an inner ring 22 made of a conductive material or an electrically insulating material, and the tip where the outer ring 21 and the inner ring 22 are assembled is an annular slit-shaped second air outlet 24.
- annular second semi-closed space 26 is formed, and a plurality of through holes 27 are formed at predetermined intervals on the base end side.
- a partition wall 31 that divides the second semi-closed space 26 in the circumferential direction is provided integrally with the inner ring 22.
- a plurality of through holes 32 are provided discretely in this partition wall 31 extending in the circumferential direction, and an elastic seal member 33 is interposed between the partition wall 31 and the outer ring 21.
- the sum of the cross-sectional areas of the plurality of through holes 32 is set to be larger than the opening cross-sectional area of the tip of the second air blowing port 24.
- the air ring 20 of this embodiment has a tip of the outer ring 21 set back from the tip of the inner ring 22 as shown in Fig. 2.
- the flow rate of the outer shaping air Sout increases slightly, but the responsiveness of the coating pattern distribution to fluctuations in the flow rate of the outer shaping air Sout becomes insensitive, and the coating pattern becomes stable.
- the tip of the outer ring 21 is set back from the tip of the inner ring 22, even if the second air outlet 24 is clogged with paint mist, it can be easily found by visual inspection.
- the rotary atomizer coating device 1 of this embodiment includes the bell cup 11 having the rotation axis CL, the first air outlet 23 in the form of an annular slit that is provided concentrically with the rotation axis CL and blows out the inner shaping air S in from the back surface of the bell cup 11, and the second air outlet 24 in the form of an annular slit that is provided concentrically with the rotation axis CL and has a larger diameter than the first air outlet 23 and blows out the outer shaping air S out from the back surface of the bell cup 11.
- This allows for a coating pattern in the form of a truncated cone with steep peripheral sides and a flat center.
- a coating film with a uniform thickness distribution can be obtained even with a small number of recoatings.
- the coating speed can be reduced to, for example, 600 mm/sec or less, improving the coating efficiency of the paint.
- the inner shaping air S in is non-directional in the circumferential direction of the first air outlet 23, so that the central flat portion of the coating pattern, which has a frustum shape, can be made symmetrical.
- the flow rate of the outer shaping air S out is equal to or greater than the flow rate of the inner shaping air S in , so that the outer shaping air S out shields the mixed gas of the inner shaping air S in and the atomized paint particles so that it fills the front of the bell cup 11.
- the ratio of the opening cross-sectional area of the first air outlet 23 to the opening cross-sectional area of the second air outlet 24 is 3:1 to 4:1, so a coating pattern can be created that has a truncated cone shape with steep peripheral sides and a flat center.
- the coating device further includes an air ring 20 that is concentric with the rotation axis CL and surrounds the bell cup 11, with a second air outlet 24 formed at its tip, and the annular slit-shaped gap between the tip of the inner circumferential surface of the air ring 20 and the tip of the bell cup 11 serves as the first air outlet 23, and original air that becomes the inner shaping air S in is supplied to the first semi-closed space 25 between the inner circumferential surface of the air ring 20 and the back surface of the bell cup 11, so that the first air outlet 23 can be configured with a simple structure. Also, the accumulation of paint mist that adheres to the outer surface of the bell cup 11 due to the airflow induced by the inner shaping air S in can be suppressed.
- the distance between the tip of the inner circumferential surface of the air ring 20 and the tip of the bell cup 11 does not exceed 2 mm, so the first air outlet 23 can be constructed with a simple structure.
- the air ring 20 has the second semi-closed space 26 to which the original air that becomes the outer shaping air S out is supplied, a partition wall 31 that divides the second semi-closed space 26 in the circumferential direction, and a plurality of through holes 32 provided in the partition wall 31. Since the sum of the cross-sectional areas of the through holes 32 is larger than the opening cross-sectional area of the tip of the second air outlet 24, when air is supplied from the second air supply device 30 to the through hole 27, the air is straightened by the plurality of through holes 32 formed in the partition wall 31.
- the straightened air reaches the second air outlet 24 in the shape of an annular slit formed at the tip of the air ring 20, and the outer shaping air S out is blown out from the second air outlet 24. That is, by providing the partition wall 31 having the plurality of through holes 32, the uniformity of the intervals of the second air outlet 24 in the shape of an annular slit can be ensured. Furthermore, by providing a plurality of through holes 32, the flow rate of air supplied to the second air outlet 24 can be made uniform.
- the air ring 20 is formed by assembling the outer ring 21 and the inner ring 22, the partition wall 31 is formed integrally with the inner ring 22, and an elastic seal member 33 is interposed between the partition wall 31 and the outer ring 21, so that it is possible to suppress axial misalignment when assembling the outer ring 21 and the inner ring 22. Furthermore, since the partition wall 31 extends in the circumferential direction, the rigidity of the opening of the second air outlet 24 is increased, and the deformation of the elastic seal member 33 can absorb vibrations caused by the flow velocity of the outer shaping air S out .
- the tip of the outer ring 21 is set back from the tip of the inner ring 22, the flow rate of the outer shaping air Sout increases slightly, but the responsiveness of the coating pattern distribution to fluctuations in the flow rate of the outer shaping air Sout becomes insensitive, and the coating pattern becomes stable.
- the tip of the outer ring 21 is set back from the tip of the inner ring 22, even if the second air outlet 24 is clogged with paint mist, it can be easily found by visual inspection.
