ROBOT ARM MECHANISM, AND DIRECT-ACTING EXTENSION/RETRACTION MECHANISM

WIPO Patent Application WO/2017/150318

A1

The purpose of the present invention is to improve the workability of exchanging rollers which form a direct-acting extension/retraction mechanism of a robot arm mechanism. A direct-acting extension/retraction mechanism provided to a robot arm mechanism is provided with first and second segments (51, 52) which are respectively coupled so as to be capable of bending. An ejection mechanism (56) is provided with: a plurality of rollers (59, 62) which firmly sandwich the first and second segments (51, 52), and support the first and second segments such that the first and second segments can move back and forth; and a drive gear (64) which meshes with linear gears of the first segments (51) to the rear of the rollers (59, 62), ejects the first segments (51) forwards, and returns the first segments (51) rearwards. The ejection mechanism is formed from separate bodies, namely a roller unit (58) provided with the rollers (59, 62), and a drive unit (63) provided with the drive gear (64). The drive unit (63) is fixed to a drum body (60) of an ascending/descending part (4). The roller unit (58) is formed so as to be capable of being attached to and detached from the drive unit (63).
