Patent number: 10189093Abstract: A guide rail is provided on an outer surface of a chuck body. A pair of fingers is disposed on the guide rail. At least one of the pair of fingers is a movable finger that is movable along the guide rail. One or two cylinder apparatuses, each of which has a rod that advances and retracts in the direction of its axial line by the action of air pressure, are provided in the chuck body. The top end of the rod extends from an end of the chuck body to the outside. An end block is attached to the top end of the rod. The end block is linked to the movable finger.Type: GrantFiled: January 20, 2015Date of Patent: January 29, 2019Assignee: SMC CORPORATIONInventors: Tadashi Saito, Koji Hara, Kouichirou Ishibashi

Patent number: 9080627Abstract: A damper hole having a large-diameter section is formed inside a body which is made of metal. A flange which fits in the large-diameter section is formed in a damper which is made of rubber and is received in the damper hole. The flange defines a cushion chamber in the large-diameter section. A gap for letting air restrictively discharge from the cushion chamber is formed between an outer periphery of the flange and an inner periphery of the large-diameter section. Motion energy of a moving object colliding with the damper is absorbed by both elasticity produced by the compressed damper and an air cushion effect produced by the flange and the cushion chamber.Type: GrantFiled: January 20, 2011Date of Patent: July 14, 2015Assignee: SMC CORPORATIONInventors: Kouichirou Ishibashi, Seiji Takanashi, Motohiro Sato

Patent number: 8801045Abstract: In a pipe joint, a release bush includes a cylindrical portion and a flange portion for pressing, provided along an outer edge of the cylindrical portion. A movable portion including a part of the flange portion and a part of the cylindrical portion is formed to move with respect to a main portion including the remaining part of the flange portion and the remaining part of the cylindrical portion, via an elastically deformable portion. The cylindrical portion of the movable portion can be moved to be aligned with the cylindrical portion of the main portion along the same circumference, by an external operating force exerted on the movable portion, while the movable portion remains in a position opposing a main body of the pipe joint when an operating force is not applied, thereby inhibiting the release bush from being pressed into a chuck despite the flange portion being pressed.Type: GrantFiled: June 12, 2008Date of Patent: August 12, 2014Assignee: SMC CorporationInventors: Masaaki Muto, Hiroshi Hanne, Kouichirou Ishibashi

Publication number: 20110068573Abstract: [Object] A pipe joint is to be provided that prevents a release bush from being accidentally pressed, and that inhibits the tube from being removed from the pipe joint unless a worker uses a predetermined tool with the intention of removing the tube from the pipe joint. [Solution] In a pipe joint including a chuck 21 with a latch claw to be engaged with an outer circumferential surface of a tube T inserted in the pipe joint thereby retaining the tube, a release bush 5 to be inwardly pressed along the tube inserted through the chuck so as to disengage the chuck from the tube is configured so as to inhibit direct manipulation thereof from outside of a main body 1 of the pipe joint, and a pressing tool 7 that can inwardly press the release bush into a position where the release bush disengages the chuck from the tube is provided as a separate member.Type: ApplicationFiled: June 12, 2008Publication date: March 24, 2011Applicant: SMC CORPORATIONInventors: Masaaki Muto, Hiroshi Hanne, Kouichirou Ishibashi

Patent number: 5363741Abstract: In a slide actuator, a central guide rail having V-shaped grooves defined therein and opened at 90 degree angles, is mounted on a cylinder body. A slide table is brought into engagement with the guide rail. Guide members having V-shaped grooves defined therein are provided inside the slide table so that they are opposed to the grooves defined in the guide rail. Cylindrical roller bearings are alternately fitted at inclinations of 90.degree. in their corresponding channels defined by the opposed grooves. Thus, when the roller bearings are rolled, the slide table is displaced with higher accuracy and a load supported by the slide table is transmitted to the guide rail from the roller bearings.Type: GrantFiled: June 17, 1993Date of Patent: November 15, 1994Assignee: SMC Kabushiki KaishaInventors: Susumu Takada, Masayuki Hosono, Kouichirou Ishibashi, Koichiro Kanda

Patent number: 4892344Abstract: In this parallel gripper suitable for gripping a work for a robot or the like, in which a pair of fingers are opened and closed by keeping the parallel condition between them by the transmission of the driving force of a fluid pressure actuator to the fingers by means of a power transmission mechanism, use is made of a pair of pistons, that are relatively slidable in a single cylinder bore under the action of fluid pressure, as the fluid pressure actuator, thereby obtaining substantially twice as large gripping force as in the case of empolying a single piston.Type: GrantFiled: May 20, 1988Date of Patent: January 9, 1990Assignee: SMC CorporationInventors: Susumu Takada, Kouichirou Ishibashi
