NOTES ABOUT
"POSSIBLE PROBLEM TOOLING":*
•
A tight die, one that is not square, or has other
tooling problems, will cause significant difficulty
and downtime. Accuracy in feeding is directly
related to how easily the feeder can position the
strip in the die. Binding, bad part ejection, or
sticking parts may cause the material to "jam" in
the die.
• The Advantage Servo Roll Feed will "try" to
overcome the "jam-up" by applying more power
to the rolls.
ONE OF FOUR OUTCOMES WILL RESULT:
•
The feed will continue to try to move the strip
(if the rolls do not slip) until the feed advance
cam opens. A Sync Fault Error will occur and
the press will be stopped by the feeder.
• The feed will apply more power to the rolls,
causing them to slip on the material. This
produces a "short-feed". In reality the feeder
did not "misfeed". The rolls were positioned
properly, the strip did not keep up, causing the
die to close and a miss-hit is produced.
• The feed applies more power to a thin strip,
causing the material to buckle somewhere
between the feed and the die set. The feeder
positioned the strip accurately, it just did not
occur in the die set.
• The feed tries to apply so much power to a heavy
strip in order to move it, that excessive current is
drawn by the servo drive. This results in the
drive shutting down to protect itself and in doing
so stops the press.
NOTE: The feed detected a problem and
emergency-stopped the press before the die
closed. In using the Advantage Servo Roll Feed,
you in fact have added a "die protection" system
to your tooling.
* A tooling problem is a problem caused by tooling
and not the Feeder itself.
