５－２．Basic operations
○Loading the screws
・Turn the power switch ON and OFF so that the brush stops vertically above
the rail.
・Open the top cover and load screws on the left and right side of the rail
evenly.
・Do not load screws above the surface of the rail.
・Be sure to determine the screw load by observing the machine while it is in
operation.
Screws with a diameter larger thanφ5 or longer than 20mm,
under the head, should not be loaded higher than the rail bottom.
○Turning ON the power
・Use only the adapter supplied with this machine to connect it to a wall outlet.
When you turn the power on, the switch lamp lights up, the motor rotates and
screws are scooped onto the rail.
・The rail vibrates to deliver screws towards the end of the rail, then the
escaper rotates to deliver screws to the pick up spot. When the screws come
to the stopper, the LED indicator lights up and the escaper stops rotating.

[CAUTION] Use only the AC adapter supplied with this machine
otherwise it may cause damage to the machine.
[CAUTION]
・The type and length of screw changes the load capacity so check and adjust
the load accordingly.
・Do not overload the hopper with screws otherwise it may cause a
malfunction or damage the machine.
・This machine accepts only steel screws. Plastic or stainless screws are not
accepted.

－9－
○Pick uping Screws
・Pick up the screws at the stopper with the screwdriver on the robot.
Use the bit guide to put the screwdriver down vertically into the screwhead's
slots.
・When the screwdriver is inserted into the screwhead slots, be careful that
no contact is made with the escaper or that the screw is not struck forcefully.
Using excessive force may alter the position of the escaper or cause damage
to the machine.
・Use a driver bit which corresponds with the screw's diameter.
・Read the screw pick uping robot manual for more details on how to use the
robot with this machine.
○Action of the escaper
・The escaper rotates 90° clockwise--> stops for about 0.6 seconds
--> and rotates again 90° clockwise.
When a screw is caught in the escaper and the notch position is altered, the
escaper automatically rotates to the left, as a reference point run, in order to
adjust the notch position and then returns to the right rotation.
・This machine continues its operation when no screw is found at the screw
pick up spot. The machine continues operating with a screw at the pick up
spot but will stop, after a certain lapse of time, if the screw is not picked up.
After the screw is picked up, the machine starts operating again. This time
lapse can be varied by adjusting the timer.
・When no screw is found at the pick up site after a certain lapse of time, the
rail vibration increases. (The vibration sound, also, increases however, this
is not a problem.) If no screw is still not found at the pick up site, then the
machine stops operating. At this time the escaper keeps rotating. When you
want to start operation again, turn the power switch OFF and ON again.

The rotation of the escaper, in the opposite
direction, is a reference point run of the escaper
motor.
The rotation of the escaper, in the opposite
direction, occurs when the power is turned on and
the starting point of the escaper is not alligned
with the reference point of the escaper motor.
During regular operation, as in the gure above,
the escaper rotates clockwise.

５－３．Adjusting the brush height
Load the screws into the scooping hopper, turn ON and OFF the
power switch so that screws are alligned into the rail groove.
・Turn ON and OFF the power switch in order to set the brush to
the left as shown in the gure on the right.
・Move the brush by hand to check that the screws, in the rail
groove, are in slight contact with the brush bristles and if needed
make the necessary adjustments.
・When the brush height is too high or low, this will have an
adverse e󰀨ect 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 move the brush assembly back so there is 0 mm
clearance.
・Turn ON the power switch to check that the brush operation is
normal.
Turn OFF the power switch before starting replacement and
adjustment.

Checking and adjusting the rail vibration
The amplitude and frequency of the rail vibration can be adjusted.
The vibration has been adjusted at the factory for screws that correspond with
the rail.
Put some screws into the rail and turn the power on. If they are delivered
smoothly, there is no need for adjustment.
The screw transport feed di󰀨ers depending on screw type.
For screws with a low transport speed, or screws that easily jump, perform the
adjustment according to the following procedure.

Step1: Amplitude VOL Maximum
Step2: Frequency VOL Adjust where screew ows fastest.
(Around the middle)
Step3: If the vibration is too strong, decrease the amplitude.
Use the supplied resin driver. VOL may be damaged.
・If the vibration is adjusted to a too large a value to increase the transport
speed, screws may jump from the rail and fall into the machine from the
clearance, failing to unload screws normally.
Adjust the vibration to a proper value that matches the loaded screws.
・With the accompanying screwdriver, turn the knob without using excessive
force.
・When no screws are scooped onto the rail for a certain period of time, the rail
vibration increases. If, still, no screws are scooped on to the rail, the machine
stops operating.

・If the rail comes into contact with the escaper, or the clearance between the
rail and escaper is too large, loosen the rail fixing bolt, hold the rail groove
and adjust the rail assembly either backward or forward. After making an
adjustment, be sure to tighten the rail xing bolt.
・When the rail comes in contact with the escaper, the escaper disk doesn't
rotate properly. When the clearance between the rail and the escaper is too
large, screws may fall down into the machine.
・After making an adjustment, try making a vibration readjustment by referring to
" 5-4 Checking and Adjusting the Rail Vibration".
・Check that the clearance between the rear hopper cover and the rail
assembly is about 0.2 mm.
・If the rail hits against the rear hopper cover, the vibration will become weak
and the screws will be delivered slowly. If the rear hopper cover is too high,
the slit between the rail and the scraper catches screws easily.
・If adjustment is required, loosen the rear hopper cover attaching bolts and
make an adjustment either up or down.

Check the lapse of time until the motor
stops by intercepting the front sensor.
(Use a small peice of paper to intercept
the sensor.)

the upper side, facing the rail.
５－９．Check and adjust the timer
The screw transport feed di󰀨ers 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.
５－１０．Check and adjust the scraper
・Check that the clearances, between the scraper right/left and the hopper wall right/
left, are around 0.4mm.
・When the scraper makes contact with the hopper wall, the rail vibration becomes
weak and the screws are delivered slowly. When the clearance between the scraper
and the hopper wall is too large, the screws may be caught easily.
・If any adjustment is required, loosen the scraper attaching screw and move the
scraper plate up or down.
・After such adjustments, if deformation on the plate has occurred so that proper
clearance and adjustment cannot be achieved, or scratches on the plates had
caused trouble in screw movement, please purchase replacement parts for best
results.

・This machine continues its operation when no screw is found at the screw pick up
spot. The machine continues operating with a screw at the pick up spot 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, covering one of the
sensors.
・Make an adjustment with the timer adjusting knob (the 3rd hole from the top) 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.(about 1 ～6 sec.)

7．PARTS ADJUSTMENTS AND REPLACEMENTS
The brush and main motor are consumable parts.
When using a di󰀨erent diameter of screw, the following items must be replaced: rail, escaper and passing plate.
These parts may be ordered separately.
The replacing and adjusting procedures are described on the next page.
When replacing any parts, a fine adjustment is required. Make these fine adjustments by reading the corresponding
contents carefully.
Before replacing any parts, be sure to remove all the screws from the hopper.
６．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 di󰀩cult, remove the rail from the machine and clean the rail groove.
Refer to the next section under『7-1 Replacing the rail assembly』 for replacing.
Before removing the rail from the machine, be sure to turn o󰀨 the power supply and take the screws out of the hopper.
If there is any dirt or a aw in the rail groove that may cause an impediment in use, we recommend the user to replace
the rail.

Pull the rail out.
Loosen the rail xing bolt.
The rail assembly of this machine can be easily replaced.
If there is any dirt or flaw on the rail groove that prevents a smooth
operation, we recommend the user clean or replace the rail. Use
the passing plate, escaper and rail assembly that correspond to the
diameter of the screws to be used.
①Remove the bottom front cover.
②Loosen the escaper assembly screws and pull out the escaper
assembly. Insert the accompanying Allen wrench into the left hole on
the front top cover and loosen the rail xing bolt.
③Pull out the rail assembly and replace it with a rail that corresponds
with the screws you will be using.
For reassembly, reverse the disassembly procedure.
After replacing the rail, adjustments are required.
Fix the rail so that it does not contact the escaper and make sure that
screws won't fall into the clearance between the escaper and rail.

Replacing and adjustment of the escaper
When using screws with a di󰀨erent diameter, replace the escaper, the
robot escaper guide, the rail and the passing plate.
Raise the holding plate to replace and adjust the necessary parts. After
replacement, be sure to adjust and check the parts in the area of the
escaper.
When you remove the escaper attaching screw, please use the driver
specied for M2 (bit No.0).

②Attach the robot escaper guide and the escaper that corresponds
with the screw's nominal diameter.
Assemble the escaper loosely as it will need adjusting later.
Note that the stopper should not be on top of the escaper.
The stopper should be laying at against the escaper guide-left.
If it is not laying at, bend it gently by hand to adjust it.

Check the position of the parts for smooth delivery of the screws.
Check that the clearances between the outside edges of the rail and
the robot escaper guide-right and left are almost even.
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.
At this time, make the top surface of the escaper even to or 0.1 ～
0.5mm lower than the rail surface.
If it's too high, the screw won't enter an escaper notch.
If it's too low, a screw will not enter a notch properly.
If any adjustment is required, remove the cover, loosen the escaper
bracket attaching screw and move it up or down, left or right and
tighten the screw.
The surface of the escaper
should be slightly lower than
the surface of the rail.

④Adjust the escaper notch position.
Turn the power switch ON while covering the sensor light axis with a
small piece of paper.
When the power is ON, the screw sensor LED lights up and the
escaper rotates around, to the starting point.(Reference point run.)
When the escaper stops, loosen the fixing screws and adjust the
escaper by hand so that an escaper notch and the rail groove align.
Tighten the escaper xing screws.
After adjustment, turn the power switch 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, in each rotation stop, aligns
with the rail groove.
After checking and adjusting each component, do an operational
check with screws loaded.
If any abnormality is found, make the said adjustments once again
in addition to the rail vibration and front/rear position adjustments.
When installing the cover, take care not to catch or pinch the wires.
