Abstract

A locking device of a transfer feeder for preventing unexpected movement of a transfer bar or a driving part therefor and capable of locking the transfer bar at any desired position exactly. The locking device includes: a feed carrier (5a); a plurality of catching plates (8) each fixed to an equalizer bar (6) provided for a lift/clamp mechanism and having a plurality of catching holes (8a) drilled at intervals lengthwise; and a plurality of locking pins (13) fixed to a press itself at several points so as to oppose the catching plates (8) and movable right and left as well as back and forth by driving units (11, 15) so that each pin can engage with any one of the catching holes.
