misoriented or do not meet the requirements set by the wiper and
qualifier are deflected down the return chute and recirculated.
The single row of caps pass by a positive pressure sensor (the air
prox - see
Figure 1-3
). The positive pressure sensor continually
blows a low volume, low pressure stream of air at the caps.
As each cap passes the sensor, the air stream blowing down creates
a back pressure. The sensor reads the back pressure, and, if the cap
is misoriented, triggers a reject airjet to blow the cap down the
return chute. Correctly oriented caps are allowed to pass the airjet
and positive pressure sensor, and continue down the conveyor.
