2.5 Feed Conveyance (IP Length Measurement)
(1) Overall/General Sequence
In this sequence, the IP sent from the IP removal unit is fed through the erasure conveyor to
the side-positioning conveyor.
During the conveyance, IP length measurement is performed.
If the IP length measurement is completed normally, the erasure lamp, if unlit, is lit.
Fig. 2.5.1 Passage through Before-Side-Positioning Conveyor and IP Length Measurement
(Overall Sequence)
(Sequence initiation requirement)
When the following requirement is met, the
sequence starts.
¥ IP feed conveyance permission OK: Fig. 2.9.1
To the conveyance path of the up-down IP
removal unit, the IP is not fed with the driving
motor, but with the belt drive, from the
before-side-positioning conveyor.
Data for determination of IP type is obtained.

Structure and Operation of Path Changeover Mechanism
The conveyance path of the before-side-positioning
conveyor is normally in the feed state.
Upon load request, the convergence path changeover
guide driving solenoid SOLC1 is turned ON to implement
path changeover.
After the IP has been passed (sensor SB2 is CLOSE
the solenoid is turned OFF to reset it to its original state.
