Abstract
A robot with at least partly externally located cables, particularly robot tool supply cables having a length reserve in the area of the A3 axis of the robot is characterized by a base part located on the robot and having elements for guiding the supply cables and with a leg pivotable against the latter on which is located at least one of the elements for supply cable guidance.
Claims17
A robot comprising:
- a first robot arm;
- a second robot arm pivotally connected to said first robot arm about a robot axis;
- a supply cable arranged externally on one of said robot arms with a length reserve in an area of said robot axis;
- a cable holder base part mounted on said one of said robot arms, said cable holder base part including a first guide element guidable of said supply cable;
- a cable holder leg pivotally connected to said cable holder base part about an axis substantially parallel to said robot axis, said cable holder leg including a second guide element guidable of said supply cable, said base part having stops for limiting pivotability of the leg;
- a tension spring element connected to said cable holder base part and to said cable holder leg, said tension spring element biasing said cable holder leg against one of said stops with respect to said cable holder base part.

A robot comprising:
- a first elongated robot arm;
- a second elongated robot arm provided with a robot hand, the second robot arm being pivotally connected to said first robot arm about a horizontal robot axis;
- a supply cable arranged externally on at least one of said robot arms with a length reserve in an area of said robot axis;
- a cable holder having a base part and a leg, said base part being mounted on said one of said robot arms, said cable holder base part including a first guide element guidable of said supply cable, said base part having stops for limiting pivotability of the leg;
- said cable holder leg being pivotally connected to said cable holder base part about an axis substantially parallel to said horizontal robot axis, said cable holder leg including a second guide element guidable of said same supply cable;
- a tension spring element connected to said cable holder base part and to said cable holder leg, said tension spring element biasing said cable holder leg against one of said stops with respect to said cable holder base part.
