(4) Sequence of Load Suction Conveyance
This is for the operation of the elevation unit.
In this sequence, the IP sucked by the suction cups is loaded into the cassette. It is in the
reverse order of IP feed.

Preprocessing: Fig. 2.10.1, Fig. 5.4.1, Fig. 5.6.1, Fig. 5.7.1, and Fig. 6.3.2
The grip rollers convey
the IP in the return
direction at the same
speed of the suction cups.
The suction cups suck
the trailing edge of the
IP and load it into the
cassette
(see illustration below).
While the suction cups
load the IP into the
cassette, it is checked
if the IP is not dropped.
After the suction cups
load the IP into the
cassette and air leak
occurs, the IP is released
from the suction cups.
After load leak, the
suction cups return to
their home position.
