5 Nozzle change
A nozzle check is performed at Station 15 to establish which nozzle is currently down.
If a different nozzle is required for pick-up, the rotary head is indexed at station 14
until the required nozzle is in position.
Another check is performed at Station 15 to confirm that the correct nozzle is cur-
rently down (E).
6 Pick-up
When the selected nozzle reaches Station 1, the cam speed is adjusted and the nozzle
lowers to the pick-up position, stops and picks up the part. If pick up offsets in the Y
direction are necessary, the NY-axis performs the necessary movements prior to pick
up. (F)
