Abstract
Abstract An industrial robot (10) having a rotary base (26) on a cylindrical stationary robot body (14), and robot arms (60,64) and a robot wrist (66) in a robot arm unit at the free end portion of the rotary base (26) is provided with a cable guide (30) along the outer side of the stationary robot body (14). The lower end portion of the cable guide (30) is pivotably connected to the stationary robot body (14) via a lower bearing member (42), and the upper end portion of the cable guide (30) to the rotary base (26) via an upper bearing member (40), in such a manner that the cable guide (30) can be turned. A robot cable (50), which has the starting point at the lower end of the stationary robot body (14), is retained by a cable holder portion (32) formed at the intermediate section of the cable guide (30), and the upper end of the robot cable (50) is guided to the robot arm unit through the rotary base (26).

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
191 words
An industrial robot comprising: .a base; a cylindrical fixed robot body fixed to the base; a swivel body mounted on the fixed robot body, and capable of swivelling about a first axis of swivel motion; a robot arm mechanism pivotally joined to the swivel body; and a cable extending means for collectively holding cables extended from the lower end of the fixed robot body toward the robot arm mechanism; characterized in that the cable extending means includes a cable guide means placed longitudinally along and outside the fixed robot body, and having an upper end pivotally supported on an upper bearing member on the first axis of swivel motion of the swivel body and the other end pivotally supported on a lower bearing member on the first axis of swivel motion of the swivel body, the cable guide means holds the cables having a starting point at the lower end of the cylindrical fixed robot body and passed through the central throughhole of the lower bearing member, and the cables are extended from the upper end of the cable guide means via a cable clamping point provided on the swivel body.
Claim 2
Dependent Claim
191 words
An industrial robot comprising: .a base; a cylindrical fixed robot body fixed to the base; a swivel body mounted on the fixed robot body, and capable of swivelling about a first axis of swivel motion; a robot arm mechanism pivotally joined to the swivel body; and a cable extending means for collectively holding cables extended from the lower end of the fixed robot body toward the robot arm mechanism; characterized in that the cable extending means includes a cable guide means placed longitudinally along and outside the fixed robot body, and having an upper end pivotally supported on an upper bearing member on the first axis of swivel motion of the swivel body and the other end pivotally supported on a lower bearing member on the first axis of swivel motion of the swivel body, the cable guide means holds the cables having a starting point at the lower end of the cylindrical fixed robot body and passed through the central throughhole of the lower bearing member, and the cables are extended from the upper end of the cable guide means via a cable clamping point provided on the swivel body.
Claim 3
Dependent Claim
69 words
An industrial robot according to Claim 1, wherein the cable guide means of said cable extending means has a cable holding section having a U-shaped cross section and extended longitudinally along the outside of said fixed robot body, and arm sections extending respectively from the upper and lower ends of the cable holding section, and the cable guide means is an integral member formed by bending a metallic plate.
Claim 4
Dependent Claim
58 words
An industrial robot according to Claim 2, wherein the .lower arm section of said cable guide means has a tongue extending through an opening formed in the fixed robot body into the interior space of the fixed robot body, and the cable guide means is joined pivotally to said lower bearing member at the end of the tongue.
Claim 5
Dependent Claim
31 words
An industrial robot according to Claim 3, wherein the angular range of swivel motion of said cable guide means is decided beforehand by the opening formed in said fixed robot body.
Claim 6
Dependent Claim
39 words
An industrial robot according to Claim 1, wherein said fixed robot body is provided with a connector box attached to the bottom thereof, said starting points of said cables are connected electrically to connectors provided on the connector box.
