ABSTRACT:
A work reversing system is provided which includes a pair of oscillation drive units, an elevation drive unit, an elevation block, and a pair of oscillation levers. The elevation block is moved up and down by an elevation lever of the elevation drive unit, and has fixed thereto a pair of guide plates which each have a guide recess formed therein. Each oscillation lever has a sliding block provided slidably thereon, which has a guide projection sliding in the guide recess. As the elevation block and oscillation levers are activated, the sliding block is moved in a direction defined by the guide recess. A work is caught by one of clamping members attached to the sliding blocks, and the clamping member is elevated and oscillated. The work is then caught by the other clamping member, and the clamping member is oscillated and lowered, so that the work is reversed.
