Patent number: 11371909Abstract: A lifespan diagnosis device for a motion guidance device including: a stress calculating means which calculates stresses during movement for each of virtual segments, the stresses during movement being stresses that occur in each segment during a movement of the moving member; a counting means which counts, for each of the segments, on the basis of the amount of displacement, the number of occurrences of the stresses during movement which repetitively occur with waving during a movement of the moving member along the track; and a diagnostic means which calculates, for each of the segments, a lifespan exhaustion ratio on the basis of magnitudes of the stresses during movement and the number of occurrences of the stresses during movement, and which diagnoses the lifespan of the motion guidance device on the basis of the calculated lifespan exhaustion ratios of the respective segments.Type: GrantFiled: December 21, 2017Date of Patent: June 28, 2022Assignee: THK CO., LTD.Inventors: Akihiro Unno, Yuki Hayashi, Yuki Tanaka, Tomofumi Ohashi, Yusuke Asano, Katsunori Kogure

Patent number: 11226001Abstract: A machining control system for machining of a workpiece movably supported by a motion guidance device having a track member which extends along a longitudinal direction and a moving member which is arranged so as to oppose the track member via a rolling element being rollably arranged inside a rolling groove and which is relatively movable along the longitudinal direction of the track member, the machining control system including: an acquisition unit which acquires prescribed machining information related to a load applied to the motion guidance device when machining of the workpiece is performed by the machining device; and an output unit which generates machining correction information for correcting a prescribed control parameter for machining of the workpiece by the machining device on the basis of the prescribed machining information acquired by the acquisition unit and which outputs the generated machining correction information to a side of the machining device.Type: GrantFiled: January 15, 2018Date of Patent: January 18, 2022Assignee: THK CO., LTD.Inventors: Akihiro Unno, Yuki Hayashi, Yuki Tanaka, Tomofumi Ohashi, Yusuke Asano, Katsunori Kogure

Patent number: 10844904Abstract: To suitably set a control gain in feedback control while suppressing an increase in apparatus size. A workpiece transport control system includes: one or a plurality of motion guidance devices; a table on which a workpiece is to be placed; an actuator which imparts a driving force to the table; a control unit which performs transport control by feedback control; and a calculation unit which calculates a transport load applied from the workpiece to a moving member of each of the one or a plurality of motion guidance devices, wherein a control gain related to the feedback control in the transport control is adjusted on the basis of the transport load in each of the one or a plurality of motion guidance devices.Type: GrantFiled: January 16, 2018Date of Patent: November 24, 2020Assignee: THK CO., LTD.Inventors: Akihiro Unno, Yuki Hayashi, Yuki Tanaka, Tomofumi Ohashi, Yusuke Asano, Katsunori Kogure

Patent number: 10738827Abstract: In a management system which manages user equipment installed in a prescribed space managed by a user, the user equipment including a plurality of motion guidance devices each including a track member, a moving member, and a plurality of displacement sensors which detect displacements of the moving member in a prescribed number of displacement directions in the moving member, on the basis of lifespan-related information corresponding to each of the plurality of motion guidance devices, a lifespan exhaustion ratio of each motion guidance device is calculated and, on the basis of the calculated lifespan exhaustion ratio, replacement object devices to be replaced within a prescribed period which constitute a part of or all of the plurality of motion guidance devices are determined. In addition, a user is notified of a replacement timing at which all of the determined replacement object devices in the user equipment are to be replaced.Type: GrantFiled: December 21, 2017Date of Patent: August 11, 2020Assignee: THK CO., LTD.Inventors: Akihiro Unno, Yuki Hayashi, Yuki Tanaka, Tomofumi Ohashi, Yusuke Asano, Katsunori Kogure
