5.7 Station 7
At station 7, in order to carry out part placement, the nozzle moves up
and down and the valve turns on and off.
5.7.1 Nozzle Up/down Stroke
The nozzle places the part on the board.
The nozzle upward and downward operation is driven by a cam
mechanism. The cam drives a lever, which drives a rod, which
drives a lever, which drives the nozzle.
The stroke of the rod is a fixed value determined by the curve of the
cam.

the solenoid is not turned off, adjustment is impossible.
(3) Attach the cam handle to the cam shaft. Turn the handle until
the cam angle indicator reads 175°.
(4) With the cam angle at 175°, adjust the adjusting rod so that
there is no space between the upper surface of the nozzle clutch
and the pusher.
