Patent ID: 6976823

Claim:
A work reversing apparatus for catching a work on a carrying table, reversing the work and placing the work back onto the carrying table, comprising: a base plate; a pair of oscillation drive units fixed to the base plate; an elevation block mounted on the base plate so as to be moved up and down; an elevation drive unit that elevates and lowers the elevation block; a pair of oscillation levers fixed to respective output shafts of the pair of oscillation drive units; a pair of guide plates fixed to the elevation block, each guide plate having a generally circular guide recess; each oscillation lever having a sliding block freely slidable in a direction through the center of oscillation, the sliding block having a guide projection slidable in the guide recess of the guide plate on the elevation block and thus sliding in a direction defined by the guide recess as the elevation block moves up or down and the oscillation levers oscillate; and a pair of clamping members mounted on the respective sliding blocks, wherein a work on the carrying table is caught by one of the clamping members, and upon operation of the elevation and oscillation drive units, the one clamping member and the other clamping member are elevated and oscillated, and upon further operation of the elevation drive unit, the pair of the clamping members move close to each other and move away from each other to catch the work by the other clamping member, and then upon operation of the elevation and oscillation drive units, the other clamping member and the one clamping member are oscillated and lowered to place the reversed work back onto the carrying table.
