Patent number: 7217229Abstract: An apparatus for automatically changing a tool tip member for a robot includes a tip member changing jig disposed in an operational area of the robot. The tip member changing jig includes a base member, a rotating member supported by the base member so as to be rotatable about a rotation axis, and tip member holding means disposed at positions that are offset from the rotation axis of the rotating member. The tip member holding means holds the tool tip member so that a central axis of relative rotation, for threadedly mounting or demounting the tool tip member on or from the tool body, extends substantially parallel to the rotation axis of the rotating member and so that rotation of the tool tip member, with respect to the rotating member, is locked.Type: GrantFiled: February 24, 2004Date of Patent: May 15, 2007Assignee: Fanuc LtdInventors: Masahiro Hagihara, Masaaki Saito, Takeshi Tsumura, Toshihiko Inoue

Patent number: 7105771Abstract: A first wrist element is provided at a distal end of a front arm of an arc welding robot rotatably about a first axial line, a second wrist element is provided on the first wrist element rotatably about a second axial line, and a welding torch is supported on the second wrist element about a third axial line. A slide mechanism which can reciprocate in a direction approximately parallel to the first axial line is provided at a proper position from an upper portion of the front arm to an upper portion of the first wrist element and a wire feeding apparatus is mounted on the slide mechanism. By sliding the position of the wire feeding apparatus in response to the attitude of the welding torch, an extending state of the torch cable can be maintained properly.Type: GrantFiled: January 9, 2004Date of Patent: September 12, 2006Assignee: Fanuc LTDInventors: Toshihiko Inoue, Kazutaka Nakayama, Masahiro Hagihara, Takeshi Tsumura

Patent number: 4729660Abstract: Light reflecting means 2R and 2L provided on both sides of a road 1 each reflect an incident light at the same angle as the angle of incidence with respect to the plane of incidence. Lights 8R and 8L emitted from a moving vehicle 3 are reflected from the light reflecting means 2R and 2L and returned again to the light emitting source and accordingly they are detected by light receivers 75R and 75L. The position of the moving vehicle 3 is calculated geometrically based on the moving distance of the moving vehicle 3 in a period obtained from the difference between the light receiving time of the light receiver 75R and that of the light receiver 75L or the light receiving angle as well as the moving direction of the moving vehicle 3 and the positions where the light reflecting means 2R and 2L are installed.Type: GrantFiled: March 20, 1986Date of Patent: March 8, 1988Inventors: Toshihiro Tsumura, Takeshi Tsumura
