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.
５-３．Checking and adjusting the brush
５-２．Amount of screws to be loaded
・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.
Loaded screws
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.
Power switch
Turn On and Off the power switch to
put the brush bristles in a h o r i -
zontal position.

５-４．Checking and adjusting the passing plate
・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.
５-５．Checking and adjusting the rail vibration
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.
・After making an adjustment, do an operational check.

５-６．Checking and adjusting the 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.
５-７．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 clearance between screws loaded in the rail and the holding
plate should be 0 ～1mm.

５-８．Checking and adjusting the timer
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.
Adjust the timer with the
timer knob.
When the optical axis of the
sensor is intercepted, the timer
will function to stop the opera-
tion of the machine.

５-9．Operation
○ Loading the screws (cf. p7)
・Open the upper cover.
When the chamber plates are at their lowest position, load screws up to 2 ～3mm below the rail groove surface.
・
Check that the screws are not loaded so as to cover the upper portion of the inclined plates.
[CAUTION] Do not overload the chamber with screws otherwise it may cause a malfunction or damage the machine.
○ Turning ON the power
・Plug the attached AC adapter into the main body and power outlet.
・When the power switch is turned ON, the power switch lamp lights up. The scooping block starts to move up and
down. The rail starts to vibrate and the escaper starts rotating.
・Screws move along the rail towards the rotating escaper which selects one screw at a time.
・The escaper rotates and deposits the selected screw at the pick up site.
・At this moment, the sensor detects a screw and the screw sensor LED lights up and then the operation stops.
・Until a screw is picked up, the machine stops operating.
・When a screw is picked up, the sensor detects this and the sensor LED light goes off and the machine resumes
operation.
[CAUTION] Do not use any AC adapter other than the one included with this unit, as it may cause damage.
５-10．Maintenance
A dirty rail groove may interfere with the screw transport speed.
Clean the dirty rail with a soft, clean cloth dipped in alcohol.
If cleaning is difcult, remove the rail from the machine and clean the
rail groove. Before removing the rail from the machine, be sure to
turn off the power supply and take the screws out of the chamber.
If there is any dirt or a aw in the rail groove that may cause an
impediment in use, we recommend the user to clean or replace the rail.
Loosen the rail xing bolts and pull out the rail assem-
bly from the rear side of the machine.

○ Operation Timing After Replacing the Main Motor
・To adjust the timing of the scooping block in respect to the brush
movement, it is necessary to adjust the gear engagement.
・
When the motor has been removed from the main body, adjust the
gear engagement of the motor, as shown in the gure on the right
then the operation timing can be adjusted. After assembling the
motor, be sure to tighten the screws again.
・When it is hard to engage the driving gear, of the motor with the
driven gear, loosen the drive shaft bracket (right) then this will
facilitate the assembly. (Refer to the gure on the right.)
・After installing the motor, switch the power ON to check the
operation timing. (Check that both right and left scooping blocks
operate almost simultaneously.)
・After doing an operation check, return the wiring arrangement to its
original status. When installing the cover, be careful not to pinch any
wires. Be careful that the wiring does not hinder the operation of
moving parts. The wiring, on the inside, should not hinder
adjustments made from the outside of the machine.
NOTE:
→ To avoid breakage, do not use excessive force with the motor
wiring.
・Assemble the motor section when the scooping blocks left and
right are in the lowest position.
・To get the left and right scooping blocks at almost the same
height, clinch the drive gear of the motor shaft and the gears
on the left and right, and tighten the motor bracket.
(M2.6 x 8 - 2 pieces)
When the right
pin is vertical, the
left pin should be
inclined about 46 ° .
The left and right scooping blocks should be at the lowest position.

Check that the clearances between the outside of the rail and the robot escaper
guide are almost even on the right and on the left.
If they are in contact, the screws cannot be delivered. If there is too much
clearance on either side, screws may fall into the machine.
When the clearances are uneven, loosen the escaper bracket attaching bolt and
make adjustments so that the clearances between the outsides of the rail and the
robot escaper guide are almost even on the left and the right.
At this time, make the top surface of the escaper even to, or slightly
lower than, the rail surface. If it's too high, a screw won't enter an
escaper notch. If it's too low, a screw will not enter a notch properly.
The clearances between the sides of the rail and
the robot escaper guide should be almost even.
The escaper top surface should be the same height as the rail
top surface or slightly lower.

③．Adjust the escaper notch position.
Turn the power switch ON while covering the sensor light axis.
When the power is ON, the screw sensor LED lights up and the escaper
motor moves around to the back, to the starting point. (Reference point
run.)
When the escaper motor is at the reference point, the escaper doesn't
move.
When it is not at the starting point, the escaper motor moves oppositely
around to return to the starting point and then stops. (Reference point
run.)
※ Before adjustment, the starting point for the escaper motor and the position
of the escaper notch are not the same.
※A reference point run is the detecting of the starting point of the escaper
motor rotation.
※Cover the sensor's optical axis with a piece of paper.
When the power is on, the escaper motor has the ability to remain
stationary.
Make a reference point run-and-stop and when the escaper motor is
stationary, then you can align the position of an escaper notch with the
rail groove.
Fine adjustments can be made for the clearance between the end of the
rail and the escaper by loosening the screws, on either side of the center
of the escaper, and moving the escaper to an ideal position.
Remember to tighten the screws again.
After adjustment, turn the power switch OFF/ON in order to make a
reference point run and check that an escaper notch and the rail
groove align.
After, remove the paper blocking the sensor's optical axis and the
escaper will start rotating.
Check that all 4 notches of the escaper, each in rotation, stop at the rail
groove.
