Patent number: 11938534Abstract: An opening-closing apparatus capable of, when using a robot arm to selectively open and close a component of a sliding nozzle device, reliably opening and closing the component to respective given positions. The apparatus comprises: a hand-like distal module engageable with an openable-closable component of a sliding nozzle device; a force sensor to detect a force received by the module; and a robot arm to which the module and the sensor are mounted. The robot arm is controllably operated to: move the module toward the component of the sliding nozzle device and engage the module with the component of the sliding nozzle device; then move the module to move the component, if the absolute value of the force detected by the sensor is equal to or less than a given threshold; and stop the movement of the module, when the absolute value of the force detected by the sensor reaches the threshold.Type: GrantFiled: March 19, 2020Date of Patent: March 26, 2024Assignee: KROSAKIHARIMA CORPORATIONInventors: Mamoru Yoshimura, Junichi Funato, Yusuke Yamaguchi, Toshihiro Imahase

Publication number: 20220288675Abstract: A sliding nozzle apparatus, configured to allow a drive unit to be attached to and detached from a slide metal frame, efficiently transmits a driving force of the drive unit to the slide metal frame. The sliding nozzle apparatus comprises a connection component attached to a slide metal frame and configured for connection with a drive unit. The connection component is provided with an opening with respect to which the drive unit can be attached and detached. The connection component is configured to allow the opening to be switched between a first position where the opening faces in the same direction as an opening-closing direction of the slide metal frame, and a second position where the opening faces in the same direction as an attaching-detaching direction of the drive unit.Type: ApplicationFiled: August 17, 2020Publication date: September 15, 2022Applicant: KROSAKIHARIMA CORPORATIONInventors: Takeshi FUJIMOTO, Akira OTSUKA, Toshihiro IMAHASE

Patent number: 11135646Abstract: A plate, a plate-holding apparatus, and a holding method for the plate for facilitating work to attach the plate to a plate-receiving metal frame of a sliding nozzle device. A gap is ensured between a to-be-held portion of the plate and an inner wall surface of an engagement groove such that, when the plate is held by engaging the to-be-held portion of the plate with the engagement groove of a holding portion of the plate-holding apparatus, the plate is movable in the longitudinal direction, the width direction, and the thickness direction of the plate.Type: GrantFiled: October 16, 2017Date of Patent: October 5, 2021Assignee: KROSAKIHARIMA CORPORATIONInventor: Toshihiro Imahase

Patent number: 10471504Abstract: A simplified and downsized coupling position switching mechanism capable of transmitting reliably and smoothly the driving force of the drive unit to the slide metal frame to switchably change a coupling position between the slide metal frame and the drive unit in the sliding nozzle apparatus. A coupling portion in the slide metal frame protrudes on the side of the drive unit and allows a rod head of the drive unit to be coupled thereto, and the coupling portion has a coupling space allows the rod head to be disposed movably in a sliding direction of the slide metal frame. A separator is inserted into the coupling space to divide the coupling space into first and second coupling chambers in the sliding direction of the slide metal frame. The coupling portion has a fitting section for allowing the separator to be fitted thereinto when it is inserted into the coupling space.Type: GrantFiled: December 10, 2015Date of Patent: November 12, 2019Assignee: KROSAKIHARIMA CORPORATIONInventors: Toshihiro Imahase, Junichi Funato
