  • Patent number: 8376339
    Abstract: 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.

  • Patent number: 7540214
    Abstract: In a manipulator-type robot of the present invention, a manipulator base contains a connection case for making cable connections to an external device. In the connection case, a signal-line connecting section for external connection is disposed on a predetermined signal line of a cable that is routed through the inside of the manipulator. The connection case contains, other than the aforementioned signal-line connecting section for making connections to the outside, an additional signal-line connecting section.

  • Patent number: 7378613
    Abstract: A robot main body is provided with a protection cover. The robot main body can be swung by a rotary pipe shaft holding a wire feed device and including a hollow portion and is structured such that a connecting cable and/or a gas hose are guided through the hollow portion of the rotary pipe shaft and are then guided through the forearm portion and base portion thereof. The protection cover covers the portions of the connecting cable and/or gas hose ranging from the connecting portion of the wire feed device and connecting cable and/or gas hose to the rotary pipe shaft.

  • Publication number: 20060294628
    Abstract: The industrial robot has cables routed, through cable-passing holes (4a, 4b) formed in a side of an arm, between the outside and the inside of the arm. The cables contain mold guide (7) disposed inside cable-passing holes (4a, 4b); cable bundle (6) that passes through the inside of mold guide (7); and filler resin (8) applied to the inside of mold guide (7). The inside of mold guide (7) is filled with filler resin (8), so that cable bundle (6) is held in place.

  • Publication number: 20060182601
    Abstract: 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.
