Abstract

For providing an improved weight compensation for a robot, the invention provides a weight compensation device on a robot, which is characterized by a plurality of parallel tension-proof, pressurized hose elements fixed by their ends to common fixing elements.

Claims

exact text as granted — not AI-modified
1 . Device for weight compensation on a robot, characterized by at least one tension-proof, internally pressurized hose element ( 6 ) fixed by fixing elements ( 7 ,  9 ;  8 ,  10 ).  
     
     
         2 . Device according to    claim 1   , characterized by a plurality of tension-proof, pressurized hose elements ( 6 ) fixed by their ends to common fixing elements ( 7 ,  9 ;  8 ,  10 ).  
     
     
         3 . Device according to    claim 1   , characterized in that the hose elements have a flexible, gas-tight inner hose ( 6 . 1 ) and tension-proof fibres ( 6 . 2 ) surrounding it.  
     
     
         4 . Device according to    claim 3   , characterized in that the tension-proof fibres ( 6 . 2 ) are oriented to the axis of the hose elements ( 6 ) by a finite angle not equal to 0°.  
     
     
         5 . Device according to    claim 3   , characterized in that the fibres ( 6 . 2 ) are arranged in rhombic manner.  
     
     
         6 . Device according to    claim 1   , characterized in that the hose elements ( 6 ) have an outer, flexible protective jacket ( 6 . 3 ).  
     
     
         7 . Device according to    claim 1   , characterized in that the hose elements ( 6 ) coaxially surround a central axis (B) common thereto.  
     
     
         8 . Device according to one of the preceding claims, characterized in that the fixing elements have plates ( 7 ,  8 ), with which the hose elements are connected in tension-proof, but detachable manner.  
     
     
         9 . Device according to    claim 1   , characterized in that the fixing elements have eyelet attachments ( 9 ,  10 ) for fixing to parts of a robot.  
     
     
         10 . Device according to    claim 9   , characterized in that one eyelet attachment ( 9 ) is connected to a robot carrousel and the other eyelet attachment ( 10 ) is articulated to the rocker ( 2 ) of a robot eccentric to its A2 axis.
