Thank you very much for selecting our Automatic Screw Feeder “NSRI Series”.
This machine can line up screws (Type M1 - M3) and supplies them one by one to
an automatic machine to help streamline screw tightening.
Different sizes of screws can be used by changing the rail, escaper, passing plate and the robot escaper guide.
It can be used wherever there is a power source for an AC adapter.

Check if the machine has the parts which match the nominal diameter
of the screws to be loaded. Check the model number of the rail,
escaper, escaper guide for the robot and passing plate by referring to
the following table. Each escaper is stamped with a model number
which matches with the type of screws that can be used. The escaper
guide for the robot is stamped with a model number which
corresponds with the types of screws that can be used.

Before delivery, each section of the machine is checked and adjusted with panhead screws matching the nominal
diameters of the ordered model.
Most screws may be usable in the initial status of adjustment however, if the height or shape of the screw head is
different or if the operation is regarded as abnormal, each section must be readjusted. If this is the case,
make the following checks and adjustments:
○ Check the screw load amount ○ Check and adjust the brush ○ Check and adjust the passing plate
○ Check and adjust the rail vibration ○ Check and adjust the holding plate
○ Check and adjust the front & rear sides of the rail ○ Check and adjust the timer
If the rail, escaper, passing plate and robot escaper guide are replaced, screws with a different nominal diameter can be
accepted. After these parts are replaced, ne adjusting is required. The respective adjusting procedures will be described
elsewhere. Please read these procedures.

Amount of screws to be loaded
．
An excessive amount of screws, loaded into the chamber, will have an
adverse effect on the screw alignment and transport.
The gure, shown at right, indicates the maximum amount of screws to be
loaded. Use this as a guide when loading the screws.
Turn the power switch ON and OFF so that the scooping block is at
・
the lower limit position.
Load screws up to approximately 2 ～ 3mm below the rail surface.
・
At this time, check that screws are not loaded so as to cover the
・
upper portion of the inclined plate.
Be sure to determine the screw load by observing the machine while it
・
is in operation.

Checking and adjusting the brush
．
Turn OFF the power supply before checking and adjusting.
Load the screws into the scooping chamber, turn ON and OFF the
power switch so that screws are aligned into the rail groove.
Turn ON and OFF the power switch so that the brush bristles are in
・
a horizontal position as shown in the gure at right.
Check that the heads of the screws, in the rail groove, are in slight
・
contact with the brush bristles.
When the brush height is too high or low, this will have an adverse
・
effect on the screw allignment and transport.
If any adjustment is necessary, loosen the brush height adjusting bolt
・
to adjust the brush height.
If the plastic portion, at the front of the brush, comes into contact
・
with the passing plate, loosen the brush assembly mounting screw
and make an adjustment either backward or forward.
Operate the machine to check that the brush operation is normal.
・
- 7 -
Screws, loaded into the chamber, must not be above the
rail-groove surface. (The maximum screw load must be
2 ～ 3mm below the rail-groove surface.)
This inclined surface, on both the right and left
inclined plates, should be visible.
Turn On and Off the power switch to
put the brush bristles in a h or izontal position.

Move the brush by hand to check
that the screws, in the rail groove,
are in slight contact with the brush
bristles and make
adjustments if necessary.

Check that the passing plate is adjusted to a height that permits
・
loaded screws to pass just within the clearance limit.
If the passing plate is too low, screws cannot pass. If the passing plate
・
is too high, it will hamper a smooth transport of the screws.
If adjustment is required, loosen the passing plate attaching bolt
・
and adjust the height.
After making an adjustment, do an operational check.
・
Note: Using the half-presses on both sides of the passing plate as
guides, slide the passing plate up or down.

This machine’s rail vibration can be adjusted.
The screw transport speed differs depending on the screw type.
Check the screw transport speed. If the rail vibration hinders a smooth
transport of the screws, it can be adjusted.
Loosen the anti-vibration screw at the rear of the machine.
・
Next, turn the vibration adjusting screw, located on the bottom of the
machine, to adjust the vibration.
When the screw is turned clockwise, as viewed from the bottom
of the machine, the vibration will increase.
When the screw is turned counterclockwise,
the vibration decreases.
If the vibration is adjusted to a too large a value to increase the
・
transport speed, the rail will hit against the escaper and screws may
fall into the machine from the clearance, failing to unload screws
normally. Adjust the vibration to a proper value that matches the
loaded screws.
(Related item: Check and adjust the front and rear positions of the rail.)
After making an adjustment, be sure to tighten the vibration plate xing bolt.

．
Holding plate
Check the position of the holding plate.
Check that the clearance between screws in the rail groove and the
・
holding plate is about 0～1mm.
If there is no clearance, a screw will be caught. If the clearance is too
・
large, a screw pile or screw jump will occur.
If any adjustment is required, loosen the holding plate attaching
・
screw and move the plate up or down.
If the holding plate makes contact with the escaper, it will affect the
・
smooth operation of the escaper movement.
After making an adjustment, check the machine operation.

Checking and adjusting the front/rear
．
positon of the rail
If the rail comes into contact with the escaper, or the clearance
between the rail and escaper is too large, when the machine is
operated, loosen the rail xing bolt and adjust the rail either backward
or forward.
After making an adjustment, be sure to tighten the rail xing bolt.
If the rail hits against the escaper, the escaper will not function
・
properly.
If the clearance between the rail and the escaper is too large,
・
screws may fall into the machine.
After making an adjustment, try making a vibration readjustment by
referring to “Checking and Adjusting the Rail Vibration”.

The screw transport feed differs depending on screw type.
This machine can make screw unloading smooth through timer adjustment. For
screws with a low transport speed, set the timer long. For screws with a high
transport speed, set the timer short.
This machine continues its operation when no screw is found at the
・
screw pick up site. The machine continues operating with a screw
at the pick up site but will stop, after a certain lapse of time, if the
screw is not picked up. This time lapse can be varied by adjusting
the timer. After the screw is picked up, the machine starts operating
again.
Check the operation by intercepting the optical axis of the sensor.
・
Make an adjustment with the timer knob at the rear of the machine
・
body (as shown in the gure on the right).
When the timer knob is turned clockwise, as viewed from the
・
rear side, the time becomes shorter. When the knob is turned
counterclockwise, the time becomes longer.
Make this adjustment, by using the accompanying screwdriver,
・
within the allowable turning range, without using excessive force.
Do an operational check with screws loaded in the scooping
・
chamber and set the timer properly.
