Specifications

The home position switch [E] informs
the CPU when all the bins are
lowered.
To move the bins up, the bin drive
motor turns clockwise (as viewed
from the front). A timing belt [F] turns
the transfer wheels.
The transfer wheels have two slots in
them 180 degrees apart. As the
transfer wheels turn, these slots
engage the bins and lift them up.
Each time the transfer wheels turn
180 degrees, they raise one bin.
To move the bins down, the CPU
reverses the bin drive motor and the
above processes reverses.
The CPU monitors the position of the
bins through pulses generated by the
wheel switch and the actuator cam
[J]. The actuator cam has two flat
sides that are 180 degrees apart and
is mounted behind the rear transfer
wheel. A pulse is generated each
time one of the lobes of the actuator
cam passes the wheel switch.
