5.6 Retaining Plate Check and Adjustment
Check the retaining plate position.
• Check that there is a clearance of about 0 to 1 mm between the head
of the working screw in the rail groove and the retaining plate.
• W ithout a clearance, screws could be stuck. Too large a clearance
could cause screws to overlap or cause them to pop out.
• If the retaining plate requires adjustment, adjust it.
• Loosen the bit guide assembly setscrew and turn the bit guide
assembly vertical adjustment screw counterclockwise with an Allen
wrench to move up the retaining plate or clockwise to move it down.
Make adjustments for a clearance of about 0 to 1 mm between the
head of the working screw.
• In clamping the bit guide assembly setscrew following the completion
of the adjustment, do so to maintain a parallel clearance between the
retaining plate and the rail.
Ensure that the clearance in the rear of the feeder is not smaller than
that in the front of the feeder.
• W hen the adjustment is complete, verify correct operations.
5.7 Timer Check and Adjustment
The working screw transfer speed varies depending on the screw type.
A longer timer interval setting is recommended for screws with a lower
transfer speed, and a shorter timer interval setting is recommended for
screws with a faster transfer speed.
• This feeder is designed to halt screw transfer with a certain delay after
a certain count of screws has accumulated at the unloading port. This
delay can be adjusted with the timer.
• A timer trimmer is found in the rear of the feeder as shown at right.
• Turn the trimmer clockwise when the feeder is viewed from the rear to
decrease the interval or counterclockwise to lengthen the interval.
• Adjust the trimmer within the range of its rotation, without using undue
force.
• Use the provided screwdriver for adjusting the timmer.
• Set an appropriate timer interval by verifying a correct feeder operation
on working screws.
