5-2. 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 figure, shownat 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 thelower limit position.
・ Load screws up to approximately 2-3 mm 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 isin operation.

5-3. 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 thepower switch so that screws are aligned into the rail groove.
・ Turn ON and OFF the power switch so that the brush bristles are in ahorizontal position as shown in the figure 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 effecton the screw alignment and transport.
・ If any adjustment is necessary, loosen the brush height adjusting bolt toadjust the brush height.
・ If the plastic portion, at the front of the brush, comes into contact with thepassing plate, loosen the brush assembly mounting screw and make anadjustment either backward or forward.

The clearance should be just enough to permit the loaded screws
to pass through the passing plate.

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 smoothtransport 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 themachine, to adjust the vibration.
When the screw is turned clockwise, as viewed from the bottom of themachine, 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 themachine from the clearance, failing to unload screws normally. Adjust thevibration 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 anti-vibration bolt.
・ After making an adjustment, do an operational check.

Turn the power switch ON while covering the sensor light axis.
When the power is ON, the screw sensor LED lights up and theescaper 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, 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.

Escaper

When the power switch is turned ON, if there is no screw at the sitewhere the screw is to be extracted, the escaper rotates with the screw
sensor LED off.

Sensor

LED screw
sensorScrew

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 to accept another screw from the rail.

This is the correct sequence of operation. Usually, there is no need toadjust the sensor as it was done when assembled in the factory.
The following are irregular situations that require adjustment:- There is no screw at the extraction site but, the LED is on and theescaper doesn’t rotate.
- There’s a screw at the extraction site, but the LED is not lit and theescaper rotates.

When a screw is not at
the extraction site,

[Reference] 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.

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 pin of IC4050.

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

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 Move the sensor bracket up slowly to reach a voltage of
between 0.25V-1.5V.

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)- 25 -
