Patent number: 8468908Abstract: A joint of an industrial robot that includes attaching part (23) having positioning member (22) embedded in one or both of two relatively rotating members, and guide (24) through which positioning member (22) projectably slides. Meanwhile, the side of the positioning member is provided thereon with a reservoir groove for a lubricant and a projection position marker for indicating a given projection length. This makeup provides an inexpensive, highly accurate, and extremely trouble-saving origin adjusting device.Type: GrantFiled: November 29, 2005Date of Patent: June 25, 2013Assignee: Panasonic CorporationInventors: Seiji Iwai, Takayasu Ohara

Patent number: 8376339Abstract: A positioner includes a housing, a table, a drive portion, a cylinder, a first winder, and a first cord. The cylinder includes a first opening at the rotation center of the table, and a second opening opposite and connected to the first opening. The first winder is disposed outside the second opening of the cylinder. The first cord includes a first lead-out portion and a first wound portion. The first lead-out portion enters the second opening, passes through the cylinder, and is led out from the table. The first wound portion is wound around the first winder according to the rotation of the table. Thus, the positioner can increase the number of air tubes or wires led out onto the table without increasing its size.Type: GrantFiled: July 8, 2009Date of Patent: February 19, 2013Assignee: Panasonic CorporationInventors: Takashi Nagai, Wataru Takahashi, Takayasu Ohara, Seiji Iwai

Publication number: 20060182601Abstract: In case a robot performs work inside the box-shaped workpiece held on a jig 16, it is possible to avoid interference with an interference point 18 in a curved recessed space of the arm by curving the first arm of the robot 9 in a direction of rotation with respect to a swing part 4 and in a direction opposite to the interior angle formed by the first arm 9 and the second arm 12. This allows work to be done as far as the work bottom 19. As a result, it is possible to reserve a wider work area 20 inside the workpiece than the work area inside the workpiece of a related art robot.Type: ApplicationFiled: June 9, 2005Publication date: August 17, 2006Inventors: Takashi Nagai, Yasushi Mukai, Wataru Takahashi, Toshiyuki Mishima, Takayasu Ohara
