Publication number: 20230356343Abstract: A filter unit is connected between a tray and a discharging duct of a spiral conveyor. The filter unit includes a first filter (perforated metal) that is fixed at a position close to the outer periphery of a conveying spiral, and a second filter (mesh filter) that rotates on the outside of the conveying spiral and the first filter. A washing nozzle sprays a washing liquid on the second filter. The chips captured by the first filter are scraped by the rotating conveying spiral and delivered back to the conveying path and the chips passing through the first filter but captured by the second filter are removed by the washing nozzle and delivered back to the conveying path. The washing liquid is sprayed at a predetermined angle from the washing nozzle and collides with vanes arranged on the outer periphery of the second filter and provides rotational force on the second filter.Type: ApplicationFiled: May 24, 2021Publication date: November 9, 2023Inventors: Takaaki MAEDA, Yoshio WATANUKI

Patent number: 11787002Abstract: A novel structure of a spiral conveyor is provided which is also suitable for conveyance of curl-shape and permanent-shape cuttings in a lathe system while suppressing the occurrence of noise caused by vibration. At the lowest point, a conveyance spiral of this spiral conveyor for conveying chips contacts the ground (the ground point P) at the lowest point of a tray, and the conveyance spiral is not in contact with a pair of rails in opposite positions on the inner surface of the tray and extending in the length direction, and small gaps t are formed between the conveyance spiral and the rails. Because it is only at the lowest point that the conveyance spiral contacts the tray, similarly to conventional rail-less designs, a low level of noise is achieved, similar to that in the rail-less designs.Type: GrantFiled: August 18, 2020Date of Patent: October 17, 2023Assignee: TOKYO SEIMITSU HATSUJO CO., LTD.Inventors: Takaaki Maeda, Sugihide Nakashima

Patent number: 10207304Abstract: A metal plate bending device, including a lower die having a main body including a pair of arc-shaped cross-sectional recesses formed on an upper surface in a symmetric design with respect to a center line, and swingable members swingably received in said recesses respectively. An upper die is arranged above said lower die movably along said center line relative to said lower die, wherein said upper die is moved toward a metal plate mounted on said lower die causing a press-push force to said metal plate to, causing said swingable members to swing and bend said metal plate along said center line. A movable plate is slideably in planar contact with a flat upper surface of the swingable members and is a flat supporting surface. During bending, said movable plate is slideable with respect to said swingable member, and is moved together with said metal plate.Type: GrantFiled: May 25, 2017Date of Patent: February 19, 2019Assignee: TOKYO SEIMITSU HATSUJO CO., LTD.Inventor: Takaaki Maeda

Patent number: 9878359Abstract: [Problem] To provide a bending device with a novel structure capable of efficiently bending a metallic plate without scratching or denting the plate. [Solution] A device (10) for bending a metallic plate (W) mounted on a pair of movable plates (35, 35) by applying pressing force to the metallic plate by an upper die (20) along a central axis (X), wherein against the biasing force of a coil spring (45), the movable plates move with the extension of the metallic plate during bending, and therefore the metallic plate is not scratched. The upper surface of each of the movable plates is a perfect flat surface, and therefore does not dent the metallic plate being subjected to the pressing force by the upper die.Type: GrantFiled: March 3, 2015Date of Patent: January 30, 2018Assignee: TOKYO SEIMITSU HATSUJO CO., LTD.Inventor: Takaaki Maeda
