Abstract
A device in an industrial robot permitting rapid exchange of tools in spite of the fact that the tools require both electric and pneumatic operating pulses. The robot hand supports a housing and a tool holder attachment rotatably journalled in the housing, a tool holder being detachably arranged in the tool holder attachment. An automatically breakable electrical connection is provided between the housing and the tool holder by means of slip rings, arranged either on the housing or on the tool holder, and collector shoes, making contact with the slip rings, on the corresponding tool holder or housing.
Claims8
An industrial robot having a hand which carries a housing, a tool holder attachment rotatably journalled in said housing, and a tool holder detachably arranged in said attachment
- characterized in that
- a demountable electrical connection is provided between said housing and said tool holder by means of slip rings arranged on one of said housing and said tool holder and by means of collector shoes, making electrical contact with said slip rings, on the respective other one of said tool holder and housing.
In an industrial robot having a robot arm, supporting a hand which carries a housing in which a tool holder attachment is journalled to rotate about a rotational axis, the tool holder attachment being designed to receive a tool holder which turns with said tool holder attachment about said axis relative to the housing;
- the improvement which includes
- at least two separated rings of electrically conducting material mounted on the housing concentric with the rotational axis and, mounted on the tool holder, a respective contact shoe for each ring,
- means being provided for feeding electrical power from said contact shoe to an electrical motive means of a robot tool carried by said tool holder.
