Tracking Conveyor

The conveyor is tracking correctly when it remains centered between the roller brackets on each side of the conveyor. Adjusting the tracking is only necessary if the conveyor belt starts rubbing against the roller brackets.

2.Loosen the rear adjustment nuts on both sides of the conveyor.

3.Start the conveyor belt.

4.Adjust the roller bracket that the belt is hitting by turning the front adjustment nut counter- clockwise half of a turn, and watch the belt tracking. Note—The effect of the adjustment can sometimes take two minutes before the results are fully apparent.

If the tracking was not corrected by this adjustment, proceed to step 5. If the tracking was corrected, skip to step 6.

5.On the side that the belt tracks away from, turn the front adjustment nut clockwise half of a turn, and watch the belt tracking.

If the tracking was not corrected by this adjustment, repeat step 4.

6.When the conveyor belt is tracking in the center of the roller brackets, run the con- veyor for at least two minutes to ensure that it will remain tracking correctly.

—If the tracking was not corrected by this adjustment, repeat step 4.

—If the belt is tracking in the center of the infeed roller, but not centered on the outfeed roller, go to step 7.

—If the belt is tracking in the center of both rollers, go to step 9.

7.Adjust the outfeed end of the conveyor by loosening the bolts on the outfeed bear- ing housing (similar to the bearing housing shown in Figure 63) and sliding it forward or backwards.

8.Retighten the bearing housing bolts and run the conveyor to check the tracking.

—If the tracking was not corrected by this adjustment, repeat step 7.

9.Tighten the rear adjustment nuts against the bracket plates, then tighten the front adjust- ment nuts against the bracket plates to make sure that the tracking adjustment will not slowly change during normal operation.
