摘要:
A robot including a forearm section (18) with a through passage (34), a wrist section (20) articulated on the forearm section, and an umbilical member (38) inserted through the through passage of the forearm section and provided along the wrist section. The robot includes a tool managing and relaying unit (46) mounted on the forearm section close to the through passage and provided with a connection part (44) to which the umbilical member is connected, and a mount mechanism (68) carrying the tool managing and relaying unit movably between a first position where the connection part is disposed adjacent to an opening of the through passage and a second position where the connection part is spaced from the opening of the through passage, and releasably securing the tool managing and relaying unit to the forearm section at the first position.

In an umbilical member processing mechanism of a robot, a working tool managing unit umbilical member (50) for supplying at least one of the power, the signal and the material to a working tool managing unit (34), is guided from a rotary barrel in the longitudinal direction of an upper arm on a side face of the upper arm (14) located on the opposite side to the side attached to the rotary barrel (12) and then guided onto a front side (18b) of a front arm (18). Next, the working tool managing unit umbilical member (50) is connected to the working tool managing unit (34) through a side of the front arm located on the opposite side to the side on which the upper arm is attached. Further, the working tool managing unit umbilical member is connected to the working tool managing unit being relayed by an umbilical member junction portion (39) attached to a side or a front side of the front arm. Due to the foregoing, even in an arm posture in which a front arm rear portion having the working tool managing unit passes through inside the upper arm, the umbilical member or the working tool managing unit does not interfere with the upper arm.

An arc welding apparatus (12) includes a single-electrode type welding torch (18), a single wire feeder (24) supplied with a plurality of welding wires and having a plurality of wire driving means for driving the plurality of welding wires, and a welding controller (26) for controlling operations of the welding torch (18) and the wire feeder (24). The welding controller (26) selectively operates any one of the plurality of wire driving means to feed only a single welding wire to the welding torch (18) and performs the arc welding. An arc welding robot system (10) includes the arc welding apparatus (12), a robot mechanical part (142,144,146,148) for holding the welding torch (18) of the arc welding apparatus (12), and a robot controller (16) for controlling operation of the robot mechanical part (142,144,146,148).

A managing structure for an umbilical member includes a flexible conduit (8) for leading an umbilical member inserted therein from a front arm (10) of a robot to a working tool (H) mounted on a wrist of the robot, a first conduit mounting portion (4a) provided adjacent to the front arm, and a second conduit mounting portion (Hc) provided adjacent to a point where the umbilical member is connected to the working tool (H). One end (8a) of the conduit (8) is attached to the first conduit mounting portion (4a), while the other end (8b) of the conduit (8) is attached to the second conduit mounting portion (Hc). The conduit (8) is laid so that a section thereof between the first conduit mounting portion (4a) and the second conduit mounting portion (Hc) does not contact the body of the robot.

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.
摘要:
An operation line tracking device for a robot for performing an operation with a tool mounted on the robot while tracking an operation line using a sensor wherein a detection failure of the sensor is restored by automatically changing or resetting a detecting condition of the sensor when the sensor fails in detecting the operation line. If a detection failure occurs for a cause of excessive or too small quantity of light impinged on light receiving elements of a laser sensor, a laser output intensity is automatically changed. If a detection failure occurs for a cause of basing of the quantity of the impinged light, an orientation of the laser sensor is automatically adjusted. If a detection failure occurs for a cause of biasing of position of the operation line in the visual field of the laser sensor, the position of the laser sensor is automatically adjusted. If a detection failure occurs for a cause of detection of an unexpected line, an algorithm for detecting the operation line is replaced with another one. Thus, the detecting condition is automatically changed or reset in accordance with the cause of the detection failure, and the tracking operation of the robot is automatically restarted.
