INDUSTRIAL ROBOT

PROBLEM TO BE SOLVED: To prolong a service lifetime of a filament body by preventing the filament body arranged to the robot from being damaged. SOLUTION: A slider 4 driven by a J1 shaft is mounted to a linear guide 3 installed in a base 1. A clamp slide rail 11 engaged with a movable filament body clamp 12 is installed in the slider 4. The filament body 10 is clamped with the movable filament body clamp 12 after the U-turn in the base 1 and fixed to a clamp 13 after passing through the inside of a pipe 14 through a lower end opening of the filament body protection pipe 14. A short and flexible connecting member 15 connects between a rotatably mounted ring 16 and the movable filament body clamp 12. When a distance between the filament body protection pipe 14 and the movable filament body clamp 12 is increased by the operation of a J2 shaft, the flexible connecting member 15 is pulled and the movable filament body clamp 12 is moved. Tensile force is not applied to the filament body 10. Friction with the filament body protection pipe 14 does not occur. The movability of the movable filament body clamp can be imparted by a degree of freedom of rotation around two shafts. COPYRIGHT: (C)2005,JPO&NCIPI
