The servo motor 127 is fixed to the frame 11, and the rack 125 is fixed to the reciprocating rail 124. The output shaft of the servo motor 127 mounts a gear that mates with the rack 125. Therefore, the reciprocating rail 124 can be linearly reciprocated by the periodical forward and reverse rotation of the servo motor 127. The gear and the rack 125 are matched to realize the linear motion of the reciprocating rail 124, so that the motion of the reciprocating rail 124 is more accurate, and meanwhile, the transfer conveying line has a longer service life.
