5.10.2Nozzle Pre-switch Check
Before nozzle change is carried out at station 11, the nozzle position
is checked. This check, called the nozzle pre-switch check, uses two
sensors to detect the position of the S, M, L nozzles. Because this
check is performed, no problems arise if the nozzle position is
changed by the operator at a station before station 10.
Fig. 5-45 Nozzle Pre-switch Check Mechanism
Follow the procedure below to adjust the nozzle pre-switch check
sensors.
(1) Set the cam angle to 0° and select the L nozzle. The S and M
nozzles cannot be adjusted. If the L nozzle is not selected,
remove the Station 8 holder, select the L nozzle, then re-attach
the holder and rotate the unit forward to station 10.
(2) Set the cam angle to 235° and adjust the sensor attachment
bracket so that the distance between the nozzle change sensor
tip and the holder is 5 mm as seen from the side ( see figure 5-
47).
(3) Line up the center (looking from above) of the nozzle change
sensor and the holder (see figure 5-47).
(4) Adjust the amplifier volume. Set the "on" position of sensors 1
and 2 to the point where the LED changes from red to green,
and then set the volume to the next higher mark on the dial.

5.11 Station 11
At station 11, nozzle switching is carried out. The nozzle is selected using
Part dat and the data from station 10's pre-switch check.
The nozzle switch operation is driven by a cam mechanism. The cam
drives a lever, which drives a shaft, which drives a lever, which drives the
holder. This sequence of drive transmission combines with the action of
the cylinder.

Adjustment requires a special jig.
