3.3 BIN DRIVE MECHANISM
The bin drive mechanism moves the bins up and down to receive copies.
There are four pins on each bin. Two pins fit into the slots [A] in both the front
and rear side frames; the pins slide up and down in these slots. The other
two pins fit into the slot in the helical wheels; as the helical wheels turn, these
pins move up and down, and the other pins move up and down in the slots at
the other end of the bin.
The bin drive motor [B] drives the helical wheels [C] through timing belts as
shown. When the motor rotates clockwise, the bins lift; when it rotates
counterclockwise, the bins lower. There is a wheel sensor [D] located under
the actuator [E] on the rear helical wheel; the actuator has a slot which
detects when the helical wheel has rotated once.
When the bins are advanced, the helical wheels rotate once for each step. As
the pitch of the spiral on the helical wheel is greater when the bins are at the
stapling and paper exit area than when the bins are elsewhere, the amount of
bin shift is greater when the bins are at the stapling and paper exit area. This
leaves enough space to staple and stack the copies. Also, this reduces the
total machine height.
