(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, theescaper motor moves oppositely around to return to the starting point
and then stops. (Reference point run.)

Oval hole
Adjust an escaper notch position byloosening the screws and rotating theescaper.

* Before adjustment, the starting point for the escaper motor and the position of theescaper 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 notchwith 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 thecenter of the escaper, and moving the escaper to an ideal position.
Remember to tighten the screws again.
After adjustment, turn the power witch OFF/ON in order to make areference 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.
[Reference] It is possible to adjust, finely, the groove section as you adjust the positionof the escaper bracket. However, to do so, you must do as follows: *See ②“Check and Adjust “on page 20.
・There must not be any contact between the rail, the stopper and the escaper guideright. Being in contact stops feeding the screws.
・The escaper top surface should be the same height as the rail top surface or slightly
lower.

Cover the sensor’s optical axis with paper.
You can make fine adjustments for width clearance between the endof the rail and the escaper.
Also, you can make fine adjustments for height clearance between
the rail surface and the escaper surface.

The escaper rotates and accepts a screw from the rail.
As the escaper rotates, it brings the screw to the screw extraction site.
At this time, the sensor detects the screw, the LED lights up and theescaper stops.
When the screw is removed from the extraction site, the LED lightgoes off and the escaper rotates.

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 andthe starting point of the escaper is not alignedwith the reference point of the escaper motor.
During regular operation, as in the figure above,the escaper rotates clockwise. (cf.)

⑤ . Checking and adjusting the sensor
Check when required.
When checking is required, take the rear cover off and check thevoltage level of No.7 pin of IC4050 on the base and adjust the sensor
bracket. When measuring the voltage level, the metal part of the main
body is the ground.
When a screw is not at the extraction site, turn the power ON.
Next loosen the 2 sensor bracket attaching bolts and do the following:

Remove the rear cover of the machine.
While adjusting the sensor check the voltage of No.7 pinof IC4050.

No.7 pin of IC4050① . Pull the sensor bracket down and check if the voltage is over 4V and if thesensor light is ON. At this time, the escaper is stopped.
② . Next, while checking the voltage level, slowly push the sensor bracket
up which causes the voltage to decrease. When the voltage is around
0.25V-1.5V tighten the sensor bracket. During this procedure when thevoltage is around 2.5V, the LED screw sensor turns OFF and the escaperrotates.

When there is no screw at the extraction site, the voltage is 0.25V-1.5V
and the LED screw sensor is OFF.
When there is a screw at the extraction site and the voltage is over
3.5V, the LED screw sensor is ON. This is a general standard.
The borderline, if there is a screw in position or not, is 2.5V.

①．Push the sensor bracket down and check if the voltage is more than 4V.
②．Lift the sensor bracket up slowly to reach a voltage of
between 0.25V - 1.5V.

8. MISCELLANEOUS
8-1. Overload protective circuit
This machine is equipped with an overload protective circuit.
Normally, the driving motor rotates forward to feed screws to the escaper continuously.
However, if there is an overload at the driving section, the driving motor rotates backward for a certain amount of time andthen returns to normal rotation.
When the cause for the overload is removed, during the reverse rotation, the driving motor returns to the normal rotation.
If the cause of the overload is not removed, during the reverse rotation, the driving motor repeats the sequence of reverse
rotation/normal rotation, reverse rotation/normal rotation to shut off the power to the driving motor.
During this time, the escaper action is not stopped.
When the power to the driving motor is shut off, turn OFF the power switch and remove the cause of the overload.
For example, when too many screws are loaded into the scooping chamber, reduce the quantity of loaded screws to aproper level.
If any screw is caught in the transport section, remove it.
After removing the cause of the overload, turn ON the power switch to operate the machine. (Power reset)- 28 -
