Belt Tracking - HYTROL ProSort SC1 Manual De Instalación Y Mantenimiento

• Belt Tracking

TRACKING THE BELT
The belt is tracked by one of two methods:
1. By manually adjusting drive pulley, tail pulley, return idlers, and snub
idlers.
2. By manually adjusting the diverter bank.
PRE-TRACKING INSPECTION
Before attempting to physically track the belt:
1. make sure conveyor is level across the width and length of unit Adjust sup-
ports as necessary.
2. Check to make sure: drive pulley, tail pulley, snub idlers, and all return
idlers are square with conveyor bed. See illustrations 7 thru 8B. dimension
"A" should be equal on both sides of unit.
3. make sure belt has been properly threaded through conveyor. See "Belt
Installation' page 6.
4. Check for improper loading. Feed should be in direction of belt travel,
centered on belt.
5. make sure belt lacing has been installed correctly.
TRACKING BELT THROUGH dIVERTER BANK
(SEE FIGURE 6C)
Condition 1 (When belt is running in the direction (FLOW) With the arrow, but
belt drifts towards Side "Y"):
1. Remove center bolt and nut point (A).
2. Loosen bolts and nuts points (B).
3. Loosen jam nut point (C).
4. Tighten jam nut point (d) until belt tracks to desired location. (1/16" incre-
ments). (Let belt make at least one full revolution between 1/16" adjust-
ments.)
5. Tighten jam nut point (C).
6. Tighten bolts and nuts points (B).
Condition 2 (When belt is running in the direction (FLOW) with the arrow, but belt drifts
towards Side "X"):
1. Remove center bolt and nut point (A).
2. Loosen bolts and nuts points (B).
3. Loosen jam nut point (d).
4. Tighten jam nut point (C) until belt tracks to desired location.
5 Tighten jam nut point (d).
6. Tighten bolts and nuts points (B).
Note: When belt tracking adjustments are made,they should be minor (1/16
in. at a time.)

ImPORTANT: When belt tracking adjustments are made, they should be
minor (1/16 in. at a time on idlers, etc., should be sufficient.).
Give the belt adequate time to react to the adjustments. It may take several
complete revolutions around the conveyor for the belt to begin tracking prop-
erly on long, slow conveyor lines.
A) Stand at tail pulley looking toward drive and note what direction belt is
traveling.
B) Having observed belt and determined tracking problem, follow procedures
in "How to Steer The Belt", See Figure 8C.
HOW TO STEER THE BELT
Condition 1. . .When the belt is running in the direction (FLOW) with the arrow,
but tracking (drifting) towards Side "X", move the Snub Idler nearest the
INFEEd end of Side "Y" towards the dISCHARGE end of the conveyor.
Condition 2. . . When the belt is running in the direction (FLOW) with the
arrow, but tracking (drifting) towards Side "Y", move the Snub Idler nearest
the INFEEd end of Side "X" towards the dISCHARGE end of the conveyor.
If Belt direction (FLOW) is reversed, all the above conditions will remain the
same as in Figure 8C, except you are now viewing the conveyor from the
opposite end.
If belt continues to track improperly, re-check all items covered in "Pre-
Tracking Inspection" and make corrections as necessary.
NOTE: In all conditions, you are viewing the Conveyor Belt from the INFEEd
end. All corrections will be made from the INFEEd end of conveyor.
