3.4 Blow station
3.4.1 Shaft-blow function
The air-blow station provides a high-pressure air blowing cleaning function to blow foreign matter from the
nozzles, inside the shafts and nozzl tip (This motion is called Nozzle Shaft blow).
The air-blow stations are installed at front and rear side of machine.
Five holes shown in the figure below are used to blow the heads separated in groups. See"3.4.2 Manual
nozzle shaft blow procedure" for practical method.
Here, components are normally disposed into the dump box. But regarding to the disposal of very small
components as such 1005 size or smaller, if some components or dust are recognized at checking after
disposal operation (by negative pressure check or side view recognition), the air-blow station continues shaft
blow dump to dispose very small components.
See the section"3.4.4 Shaft blow dump of very small components" for practical method.
