12 February 1992 BIN DRIVE MECHANISM
[B]
[J]
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
[C]
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.
