Trouble
Cause
Corrective measures
Weak screw
feed on rail
Rail vibration abnormality
The rail vibration may be weakened and the screw
feed may be weakened.
Perform the following processing and turn on the power again.
①
Vibration adjustment
Refer to 6-1 Checking and adjusting rail vibration, and adjust the vibration.
②
Foreign matter mixed
There is a possibility that foreign matter has entered the gaps between
the vibrating parts and the vibration has weakened. Blow the solenoid,
rail cover, etc. with air.
③
Solenoid gap abnormality
：
Adjust the gap with a 0.5 mm shim.
④
Interference of parts
：
Check for interference with the following parts.
・
Interference caused by screws mixed in the rail vibrating part
：
Removal of screws
・
Interference between rail and slide block
：
Adj. See 6-9-5
・
Interference between the rear hopper cover and the rail
：
Adj. See 6-7
・
Interference between the scraper and the hopper wall
：
Adj. See 6-8
・
Interference between the hopper wall before and after and the rail

Slide unit does
not move
Abnormal screw outer sensor
The screw outer sensor may be detecting the
screw at all times.
A dust may have adhered to the surface or slit of the screw output sensor.
Remove the sensor and remove a dust adhering to the sensor surface and
slits. When assembling, insert the slit on the light receiving side (the
sensor surface is black).
Air-pressurized
delivery is
performed but
do not count
Abnormal of the screw count sensor of the
shoot box
The screw count sensor may be in a state where it
is constantly detecting screws.
A dust may have adhered to the surface or slit of the screw count sensor
Remove the sensor and remove a dust adhering to the sensor surface and
slits. When assembling, insert the slit on the light receiving side (the sensor
surface is black).
Small quantity taken out
Foreign matter may be mixed in. Clean the inside of the screw path. If it
recurs, please contact us.
Large quantity taken out
It is possible that the screw count sensor is abnormal or multiple screws
are stuck in the tube. If the screw count sensor is abnormal, replace the
sensor. If multiple screws are mixed, take corrective action. In case of
recurrence, please contact us
