Patent number: 9073077Abstract: A spray gun (1) forms a desired spray pattern by atomizing by means of atomizing air (A) a spray liquid which is sprayed from a liquid ejection port (44) opened/closed by a needle valve (4), and jetting pattern air (P) to the flow of spray mist of the atomized spray liquid. A nozzle taper angle (?1) is set in a range of 5° to 15°, and a cap taper angle (?2) is set in a range of 20° to 40°. Atomizing air (A) is jetted from a nozzle insertion hole (58) toward the center of a nozzle (3). Pattern air (P) is jetted in a spreading suppressed region (R) wherein the flow of the spray mist does not spread over an area greater than or equal to a predetermined cross-sectional area, to the flow of spray mist, and as a result, the spray mist is more uniformly sprayed over a wide range.Type: GrantFiled: October 19, 2010Date of Patent: July 7, 2015Assignee: FREUND CORPORATIONInventors: Kazuomi Unosawa, Shigemi Isobe, Takerou Adachi, Hirotsune Yasumi, Kouji Fukuda, Naoya Watanabe

Publication number: 20100178202Abstract: Processing vessel (1) is formed by overlaying a filter casing (2), a spray casing (3), a material container (4) and an air supply unit (5). Airtightnesses between respective units are maintained by airtight junctions (61 to 63). In the airtight junction (61), two seal portions (91 and 92) are radially provided, and U-seals (64 and 65) are contained. The U-seals (64 and 65) vertically move within seal grooves (67 and 68) through supply and exhaust of air to/from cylinder chambers (69 and 71), to thereby attain close contact with or detachment from flange (74). During particulate material processing, the airtightness of the seal portion (91) is maintained by the U-seal (64). During processing vessel washing, the airtightness of the seal portion (92) is maintained by the U-seal (65), to thereby prevent exposure thereof. Simultaneously, the U-seal (64) is raised, to thereby attain washing of the seal portion (S1) during the particulate processing.Type: ApplicationFiled: May 21, 2007Publication date: July 15, 2010Inventors: Shigemi Isobe, Kuniaki Yamanaka, Kazuomi Unosawa, Narimichi Takei

Publication number: 20080006290Abstract: A cartridge filter 7 is vertically movably placed in a processing vessel 1 having a cylindrical profile. An ultrasonic washer 55 is fitted to the lateral wall 3a of the spray casing of the processing vessel 1. Washing liquid 56 is injected into the processing vessel 1 and the filter 7 is moved downward and immersed in the washing liquid 56. The washer 55 is activated under this condition to wash the filter 7. Since the washer 55 is arranged near the filter 7, the ultrasonic oscillation is easily transmitted to the filter 7 to efficiently remove the foreign objects adhering to the filter 7. Thus, with this arrangement, it is possible to wash the filter 7 in the processing vessel 1 without removing the filter 7 from a fluidized bed apparatus. In a filter washing apparatus 101, a cartridge filter 103 is contained in a processing vessel 102 and immersed in washing liquid 110.Type: ApplicationFiled: July 6, 2007Publication date: January 10, 2008Inventors: Kuniaki Yamanaka, Shigemi Isobe, Kazuomi Unosawa, Narimichi Takei, Yuriko Hirai, Takashi Terada

Publication number: 20070209582Abstract: A rotating drum 3 has ventilation sections 6 that can ventilate the inside of the drum and the outside of the drum in the coating processing. To the ventilation sections 6, a panel unit 41 having arranged therein plural hollow pipes 42 through which cold water passes is attached. The hollow pipes 42 are fixed to a base plate 44 in parallel with each other, and a gap “G” is provided between the adjacent pipes. The base plate 44 is provided with a communication hole 45, and the hollow pipes 42 are so arranged as to face the communication hole 45. To both ends of the hollow pipes 42, charge/discharge collecting pipes 46a and 46b are fixed. In the coating processing, cold water is arbitrarily supplied to the hollow pipes 42 through the charge/discharge collecting pipe 46a to cool the drum 3 so as to bring about the temperature difference between the inside of the drum and processing objects, which can prevent coating base materials from adhering to the inside of the drum.Type: ApplicationFiled: February 21, 2007Publication date: September 13, 2007Inventors: Narimichi Takei, Kazuomi Unosawa, Kuniaki Yamanaka, Shigemi Isobe

Publication number: 20070082045Abstract: A seamless capsule manufacturing device comprises a multiple nozzle 7 for ejecting liquid drops into hardening liquid 10 and a flow passage tube 11 for containing hardening liquid 10. The flow passage tube 11 has a deformation section 28 that includes an inlet part 25 and a formation tube part 28b showing a cross sectional area smaller than the inlet part 25. The liquid drops ejected from the multiple nozzle 7 into the hardening liquid 10 are once made to become spherical liquid drops 26 in a sol state at the inlet part 25. The liquid drops 26b are introduced from the inlet part 25 into the deformation section 28 while they are still in a sol state. As hardening liquid 10 is introduced from the inlet part 25 into the formation tube part 28b, its flow rate is changed and the liquid drops 26 are deformed due to the change in the flow rate to produce nonspherical seamless capsules SC.Type: ApplicationFiled: November 2, 2004Publication date: April 12, 2007Inventors: Kuniaki Yamanaka, Kazuomi Unosawa, Narimichi Takei, Shouji Konno, Masayuki Ikeda
