Patent number: 10518374Abstract: A chip conveyor includes: a cover body; a guide plate configured to guide chips, which are conveyed inside the cover body, so as to be directed from a chip receiving position toward a chip discharging position; a case attached to the cover body and having an internal space provided therein; and a float switch configured to detect, based on a coolant flowing from inside the cover body into the internal space, that a liquid level of the coolant inside the cover body is equal to or greater than a prescribed liquid level. The cover body includes a first space and a second space that are partitioned from each other by the guide plate. The cover body is provided with: a first opening allowing communication between the first space and the internal space; and a second opening allowing communication between the second space and the internal space.Type: GrantFiled: March 23, 2018Date of Patent: December 31, 2019Assignee: DMG MORI CO., LTD.Inventors: Tomoyoshi Matsuyama, Yuhei Kitade, Tatsuya Aizawa, Futoshi Yamazaki

Patent number: 9382071Abstract: A chip conveyor includes a pair of endless chains arranged in parallel, a drive mechanism turning the endless chains, a cover body having a chip receiving port and a chip discharge port at a beginning and an end of a forward path of the endless chains, respectively, scrapers connected to the endless chains therebetween, and a chip guide plate disposed along the endless chains to be in sliding contact with the scrapers. The chip guide plate is composed of a forward path corresponding part extending from the receiving port to the discharge port and a return path corresponding part bent toward a return path at the receiving port and extended along the return path. The scrapers are in sliding contact with both the return path corresponding part and a surface of the cover body facing the return path corresponding part when in sliding contact with the return path corresponding part.Type: GrantFiled: September 28, 2015Date of Patent: July 5, 2016Assignee: DMG MORI CO., LTD.Inventors: Tomoyoshi Matsuyama, Masahide Kakutani, Takuya Kichibayashi

Patent number: 9339907Abstract: To provide a chip disposal device of a machine tool which surely separates and collects a cutting fluid adhering to a chip lump, thereby capable of reducing an amount of the cutting fluid discharged to the outside of the machine. The chip disposal device includes a liquid separating part 65 which separates and collects a cutting fluid adhering to chips, the liquid separating part 65 has a mounting part 66 which is provided continuously from an inclined discharge surface 20a and is inclined so as to get lower as it goes more apart outward from the inclined discharge surface 20a, and to which a first chip lump a1 conveyed by a first scraping plate 36a is transferred. Then, the first chip lump a1 on the mounting part 66 stays on the mounting part 66 until dropping by being pushed by a second chip lump a2 conveyed by a second scraping plate 36b following the first scraping plate 36a.Type: GrantFiled: June 26, 2014Date of Patent: May 17, 2016Assignee: DMG MORI SEIKI CO., LTD.Inventors: Tomoyoshi Matsuyama, Masahide Kakutani, Yuhei Kitade, Ryutaro Oshima, Takuya Kichibayashi
