Patent number: 6988673Abstract: Segmental outward projections (12) are provided at radially opposite positions on the circumference of a tubular mount portion (7) of a main body (5), and truncated side portions (13) are provided between and at the opposite sides of the segmental outward projection (12). On the other hand, D-Shaped inward projections (14) are projected radially inward from a boundary portion between fore and rear inner peripheral surface portions (10B) and (10C) of a shaping air ring (10) in such a way as to define an outward projection passageway (15) conforming in shape with the segmental outward projections (12). At the time of mounting the rotary atomizing head (4) on the rotational shaft (3), the outward projections (12) are put in a conforming angular position relative to the outward projection passageway (15) to pass the inward projections (14).Type: GrantFiled: July 13, 2004Date of Patent: January 24, 2006Assignee: ABB K.K.Inventors: Masatoshi Kon, Tetsuya Sonoda

Patent number: 6557781Abstract: A main body (12) of a rotary atomizing head is provided with a hub fitting groove (13) on and around an inner peripheral surface (12F), while a hub member (14) is provided with a lid portion (15) of a circular disc-like shape, a plural number of leg portions (17) to be brought into fitting engagement with he hub fitting groove (13) through resilient deformation, and notched grooves (18) provided between the respective leg portions (17). Upon pushing in the hub member (14) against the main body (12), the leg portions (17) are fitted into the hub fitting groove (13) and the hub member (14) is mounted in position on the main body (12). In this assembled state, channel-like paint passages (19) are formed between the hub fitting groove (13) and the notched grooves (18), and an annular paint passage (20) is formed between the inner peripheral surface (12F) and the lid portion (15).Type: GrantFiled: July 2, 2002Date of Patent: May 6, 2003Assignee: ABB K.K.Inventor: Masatoshi Kon

Patent number: 6050499Abstract: A rotary atomizing head type coating machine which is capable of washing deposited paint from fore end portions of outer peripheral surface of a bell cup. Thinner passages are provided on the bell cup to communicate a paint reservoir with the outer peripheral surface of the bell cup. Thinner which flows out onto the outer peripheral surface of the bell cup through the thinner passages is guided toward the marginal releasing edge of the bell cup. To this end, assist air is spurted out through assist air outlet holes which are provided in the fore end face of a shaping air ring at positions radially on the inner side of shaping air outlet holes. Accordingly, at the time of a washing operation, the thinner which has come out onto the outer peripheral surface of the bell cup is forcibly pushed on the outer peripheral surface by the actions of assist air and shaping air as the thinner is guided toward the fore end of the bell cup to wash away deposited paint therefrom.Type: GrantFiled: August 3, 1998Date of Patent: April 18, 2000Assignee: ABB K.

Patent number: 5897060Abstract: A rotary atomizing head assembly employing a main body and a hub member which can be easily disassembled and reassembled whenever necessary. A ring engaging surface is provided on the inner peripheral side of a recessed hub socket on the main body, while a ring fitting groove is provided on the outer peripheral side of a cylindrical body portion of the hub member. With an O-ring set in the ring fitting groove, the cylindrical body portion of the hub member is fitted into the recessed hub socket, whereupon the hub member is resiliently retained on the main body of the rotary atomizing head by resilient retaining force of the O-ring. In this instance, the O-ring is pressed against the ring engaging surface to prevent dislocation of the hub member. On the other hand, the hub member can be disassembled from the main body by pulling the hub member in the axial direction to such a degree as to cause elastic deformation to the O-ring.Type: GrantFiled: August 28, 1997Date of Patent: April 27, 1999Assignee: ABB Industry K.K.Inventors: Masatoshi Kon, Hidetsugu Matsuda

Patent number: 5894993Abstract: A rotary atomizing head assembly of the present invention is capable of washing off paint deposits from outer peripheral surface of a bell cup in a reliable manner. A paint reservoir (15) which is provided on a bell cup (11) is communicated with the outer peripheral surface of the bell cup (11) through solvent passages (16), and an annular guide (17) is provided around the outer peripheral side of the bell cup (11). Therefore, at the time washing the rotary atomizing head assembly (10), a thinner which is spouted out from a nozzle (6) is introduced into a solvent diffusing chamber (18) which is formed between the bell cup (11) and a enlarged front portion (17B) of the annular guide (17), through the paint reservoir (15) and solvent passages (16).Type: GrantFiled: May 28, 1998Date of Patent: April 20, 1999Assignee: ABB Industry K.K.Inventors: Shinichi Takayama, Masatoshi Kon, Shogo Ikeda
