  However, in the prior art described in Patent Document 1, since the container is always in contact with the contact portion at the same position, if the contact portion is worn due to the contact friction of the container, the contact between the outer surface of the container and the contact portion. There is a problem that the contact pressure of the container becomes unstable and uneven rotation occurs in the container. Further, there is a problem that the contact portion needs to be replaced as soon as the contact portion wears, and the life is short.

  Further, since the container shaft is fixed to the arm and the outer surface of the container is in contact with the contact portion, it is difficult to adjust the contact position between the outer surface of the container and the contact portion (accuracy is required). was there.

  A coating film forming apparatus 1 according to the present invention is for manufacturing titanium balls by coating titanium dioxide powder (powder) 6 on the surface of a ball-shaped substrate 4, and a motor attached to a top plate 2 above the apparatus. 3, an output shaft 5 of the motor 3, an arm 7 that intersects the output shaft 5 and is provided substantially horizontally, a swing shaft 11 that is swingably suspended from the arm 7, and a swing shaft 11 A container 9 attached to the lower end and a nylon contact portion 10 provided in an annular shape are provided. The lower end of the output shaft 5 of the motor 3 is supported by a bearing 16 of the bottom plate 14.

  The arm 7 is provided in a cross shape in plan view around the output shaft 5, and four containers 9 are suspended from the arm 7. A swing shaft 11 of the container 9 is attached to the arm 7, and a pin 12 fixed to the swing shaft 11 is pivotally supported in a shaft hole 13 formed in the arm 7.

  The container 9 includes a substantially cylindrical container main body 15 and a container holder 17 attached to the swing shaft 11. A bearing 19 is incorporated in the container holder 17, and the container 9 is attached to the swing shaft 11. It is free to rotate. The container 9 is made of a hard material such as brass, iron, copper, SUS, metal titanium, alumina, zirconia, or ceramic.

  A male screw (threaded portion) 21 is formed at the mouth of the container body 15, and a female screw (threaded portion) 23 is formed at the container holder 17. By screwing the mouth of the container body 15 into the container holder 17, The container body 15 is fixed to the container holder 17.

  A lid 25 that closes the mouth of the container main body 15 is fixed to the container holder 17 with a screw 27 to prevent the titanium dioxide powder 6 in the container main body 15 from moving toward the container holder 17, This prevents the titanium dioxide powder 6 from entering.

  A support plate 29 whose center is cut open in a circular shape is fixed to the side plate 4, and the contact portion 10 is provided along the inner peripheral side edge of the support plate 29.

  Examples of the material of the base material 4 include glass, ceramics such as silica, metals such as steel, copper, silver, and aluminum, and metal oxides such as alumina and alumina ceramics thereof, polymer resins such as ethylene and polypropylene, One of the wood materials is used.

Titanium dioxide powder 6 is a titanium dioxide powder for photocatalyst, anatase type, rutile type,
Any of brookite type may be used. In addition to the titanium dioxide powder 6, other powder raw materials may be blended within a range that does not impair the performance of the color-modified titanium. It is preferable to include an auxiliary powder that generates an electromagnetic wave having a wavelength that enhances the catalytic reaction. As a powder that generates electromagnetic waves, minerals or natural zeolites that generate low-dose microwaves, such as those found in naturally produced phyllite, minerals or natural zeolites that generate infrared or far-infrared rays found in green zeolites, etc. Etc.

The contact pressure between the contact portion 10 and the contact portion 10 is unlikely to become unstable. Therefore, rotation irregularity of the container 9 can be prevented.

  In addition, since the container 9 is swingably suspended from the arm 7, it is not necessary to adjust the contact position between the outer surface 9a of the container and the contact portion 10 as in the prior art.

  Since the revolution radius of the container 9 is expanded by the centrifugal force generated in the container 9 due to the rotation of the output shaft 5, even if the contact part 10 is somewhat worn, the contact part 10 can continue to be used without being replaced immediately. The life of the part 10 can be extended.

  Since the mouth of the container body 15 is fixed in the holder 17 by screwing, it is not necessary to connect the container body 15 and the holder using a connecting tool when the container 9 is suspended from the arm 7, and the connection work is easy. It is. Since the contact part 10 is a nylon material, it is more durable than a rubber material and can be used for a long period of time, which is economical.

  Next, another embodiment will be described.
