Abstract
A cable arranging device for an industrial robot has a cylindrical support casing (2), a swing casing (3) supported on the support casing (2) and swingable about the axis of a swing shaft, and cables (5) interconnecting the swing casing (3) and the support casing (2). One end of a substantially C-shaped cable guide (4) is pivotally supported in the swing casing on the axis of the swing shaft, the other end of the cable guide is pivotally supported in the support casing on the axis of the swing shaft. Spaces for allowing the cable guide (4) to swing therein through a prescribed angle are defined respectively in the swing casing (3) and the support casing (2).
Claims11
A cable guiding apparatus for an industrial robot, for guiding cables interconnecting a swing shaft swingable through a prescribed angle and a support supporting the swing shaft, comprising:
- a stationary cylindrical support casing;
- a rotatable swing casing rotatably supported on said support casing;
- a cable guide, movable by abutment with the swing casing for moving and guiding the cables and having one end pivotally supported on said swing casing coaxial with said swing shaft and an opposite end pivotally supported in said support casing coaxial with said swing shaft;
- and
- openings provided in said swing casing and said support casing, respectively, for allowing said cable guide to swing therein through a prescribed angle.
A cable guiding apparatus for an industrial robot, for guiding cables interconnecting two members rotatable relative to each other through a prescribed angle, comprising:
- a stationary cylindrical support casing having a peripheral wall, a lower wall, and an upper wall;
- a rotatable swing casing having a peripheral wall, a lower wall, and an upper wall and being rotatably supported on said support casing;
- a cable guide, movable by abutment with the swing casing, for moving and guiding the cables and having one end pivotably supported on said swing casing coaxial with said swing shaft;
- the lower wall of the swing casing and the upper wall of the support casing each having an arcuate opening of a predetermined arc length for allowing said cable guide to swing therein through a prescribed angle, said arcuate opening in the lower wall of said swing casing having opposite sides which abut the cable guide for a portion of the prescribed angle of swing.
