Abstract:
1. A bar feeder comprising: a machine base; a feeder tube mounted to said machine base; a transmission mechanism mounted to said machine base; a driving mechanism mounted to said machine base, said driving mechanism having a rotary shaft, a coupling member disposed at said rotary shaft, and an actuating member disposed at said rotary shaft; a projecting rod mounted on said machine base and connected to said coupling member of said driving mechanism and rotatable with said rotary shaft between a first position where said projecting rod is engaged with said transmission mechanism and a second position where said projecting rod is disengaged from said transmission mechanism; a driven mechanism mounted on said machine base, said driven mechanism having a driven member arranged in a coaxial manner relative to said feeder tube; and a pushing rod mounted in said feeder tube and connected to said driven member for rotation with said rotary tube between a first position where said pushing rod is coupled to said transmission mechanism and a second position where said pushing rod is disconnected from said transmission mechanism; wherein when said pushing rod and said transmission mechanism are coupled together, said pushing rod is movable axially along said feeder tube, and said projecting rod is disconnected from said transmission mechanism and moved away from said feeder tube; when said pushing rod is disconnected from said transmission mechanism, said pushing rod is not movable axially along said feeder tube, and said projecting rod is coupled to said transmission mechanism and movable axially along said feeder tube.
