5.2 BIN DRIVE MECHANISM

The bin drive mechanism moves the bins up and down to receive copies under the
direction of the copier CPU. The main components of this mechanism are the bin
drive gear, the transfer wheel, and the bins themselves.
Pins on either side of each bin are inserted into the front and rear slots called bin
guides. The bins slide up and down along the bin guides. The bin guide has a special
shape at the middle as shown in the figure: X, Y, and Z. The position "Y" is the
receiving position for copies. When moving up the bins, the position "X" is the bin
inlet and "Z" is the bin outlet. On the other hand when moving down the bins, the
function of "X" and "Y" is opposite.
When the bin drive motor is energized, the drive gear is driven via idle gears. Then
the front and rear drive gears on the same shaft turn the front and rear transfer
wheels together.
The transfer wheels have three slots in them 120 degrees apart. The transfer wheels
turn 120 degrees each time. As the transfer wheels turn, these slots catch the pins of
the bin at the bin inlet and move the bin to the receiving position "Y". When the
transfer wheels turn again, the bin at the receiving position is carried to the bin outlet
and the next bin is carried from the bin inlet to the receiving position.
