Forced
vibration
continues and
stops.
Screw supply error
It occurs when the screw cannot be detected by
the rail sensor. The probable causes are as
follows.
①
There are no screws
②
Rail vibration is inappropriate and screw flow is
poor.
③
A screw is caught on the passing plate
Perform the following processing and turn on the power again.
①
Replenish the screws.

When pushed by a subsequent screw and caught on a passing plate
・
Weaken the vibration.
・
Shorten the timer to reduce the amount of screws that ride on the
scraper.
・
Raise the passing plate.
When the misaligned screws are caught on the passing plate
・
Lower the passing plate.

Air-pressurized
delivery
continues
Intermittently.
Air-pressurized delivery of screw abnormality
It occurs when the screw count sensor of the
shoot box cannot detect the screw in the air-
pressurized delivery.
Check that the screws are jammed between the main unit and the shoot
box, and then remove the screws. For recovery, turn on the power again.
The push
cylinder do not
push out
screws
Slide cylinder sensor position error
When the slide cylinder operates, the cylinder
sensor may not be ON.
Adjust the sensor position of the slide cylinder.

The slide unit
repeats
instantaneous
operation.
Abnormality of the slide unit
