Publication number: 20230271290Abstract: The present invention includes a plurality of protective bodies (13, 14, 15) sequentially connected in a moving direction of a moving body and separating a movement path of the moving body from the outside. The protective body (15) at a first end is connected to a predetermined end (12a) of an area to be protected, and the protective body (13) at a second end is connected to the moving body. The plurality of protective bodies (13, 14, 15) are configured to be expanded and contracted as a whole by movement of the moving body. A structural body (35) having a groove (35a) having a top opening and forming a flow path is provided. The structural body (35) is arranged along the protective bodies (13, 14, 15) below the protective bodies (13, 14, 15) or arranged along the protective bodies (13, 14, 15) such that the lower ends of the protective bodies (13, 14, 15) are inserted in the groove (35a) through the top opening of the groove (35a).Type: ApplicationFiled: June 22, 2021Publication date: August 31, 2023Applicant: DMG MORI CO., LTD.Inventors: Futoshi YAMAZAKI, Yohei YAMAGUCHI, Keisuke TAKAHASHI

Patent number: 10809015Abstract: A coolant supply device includes a coolant tank having first and second coolant reservoirs arranged in parallel with a predetermined space therebetween and a communicating part arranged between the first and second coolant reservoirs to allow them to communicate with each other, and formed to have a U-shaped overall shape. The coolant supply device further includes pumps pumping up coolant from the second coolant reservoir and supplying the coolant to predetermined destinations. The coolant supplied by the pumps is returned to the first coolant reservoir and flows into the second coolant reservoir through the communicating part. The first coolant reservoir has a first agitating nozzle body disposed therein for discharging coolant to assist a flow of coolant flowing toward the communicating part, and the second coolant reservoir has a second agitating nozzle body disposed therein for discharging coolant to assist a flow of coolant flowing therein from the communicating part.Type: GrantFiled: May 15, 2018Date of Patent: October 20, 2020Assignee: DMG MORI CO., LTD.Inventors: Kosuke Yamamoto, Mitsuru Taga, Futoshi Yamazaki, Yoshiaki Azuma

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
