An apparatus and method of recycling exhaust tubes used to manufacture
optical fiber includes the automated use of 1) a machine vision system
that signals a conveyor system when to stop so that a cutting machine
will cut contaminates and discoloration from an exhaust tube at the
correct place and provides an indication on whether the exhaust tube is
reusable, 2) a conveyor system to transport reusable exhaust tubes to
different stations, and 3) a robotic arm to load exhaust tubes onto the
conveyor system, and unload exhaust tubes from the conveyor system.
