Tracking
If the conveyor tracks to either side, then the tracking
must be corrected or the conveyor will load up to one
side and could rip or tear and have to be replaced.
Replacing a damaged conveyor is a big job. Always be
careful to make sure that the belt does not travel too far
to one side or the other.
Tracking the conveyor is a balancing process that takes
patience and some trial-and-error. Usually you must tight
-
en the loose side (the side the belt is tracking towards)
to make the conveyor move to the middle of the rollers,
then loosen that same side to make the conveyor stay in
position. If you adjust the bolt too much either way, then
you have to repeat the process until the conveyor rides in
the middle and stays there during continuous operation.
To track the conveyor, do these steps:
1. Make sure the drums are perpendicular to the feed
direction (parallel with the conveyor roller). Go to
Page 38.
2. Turn the conveyor ON and watch it track.
3. Determine which side the conveyor is tracking towards
(the loose side) and tension the adjustment bolt on
that side until the conveyor tracks in the opposite
direction. Note: Tracking changes may take up to
three minutes before they are noticeable.
4. When the conveyor is near the middle of the rollers or
table, loosen the adjustment bolt until the conveyor
stops moving and tracks straight.
— If the conveyor tracks too far to the other side,
then adjust the bolt as necessary to bring it back
and repeat Steps 2 & 3 until the tracking is cor-
rect.
