(3) Sequence of Feed Suction Conveyance
This is for the operation of the up-down IP removal unit.
In this sequence, the IP sucked is removed from the cassette and fed to the grip rollers of
the IP removal unit.
This sequence is also performed during a search for any remaining IP.
Fig. 2.4.3 Feed Suction Conveyance
The grip rollers rotate
at the rate of suction
cup movement.
While the suction cups
feed the IP to the grip
rollers, the IP is
monitored so that it is
not dropped.
OPEN: IP dropped
CLOSE: IP sucked
When the leading edge
of the IP is fed to the
grip rollers, air leak occurs
so that the IP is released
from the suction cups.
