D. Conveyor Installation
1. Unfold the conveyor frame so that it lies flat on the floor. As
you unfold the frame, check that the locator pins shown in
Figure 2-8 lock into the slots on the bracket.
2. Refer to Figure 2-8. Note the locations of the four tensioning
screws (2 per side) in the slotted holes on the brackets.
Loosen these screws to allow the conveyor to be properly
tensioned.
3. Lift the conveyor belt away from the frame, as shown in
Figure 2-8, to check the belt tension. The belt should lift
between 1-2" (25-50mm).
If it is necessary to adjust the belt tension, gently push the
two conveyor frame sections closer together, or further
apart, as required. Then, re-check the tension of the
conveyor belt. Repeat this step as necessary until the
proper belt tension is achieved.
4. When the belt tension is correctly adjusted, tighten the two
tensioning screws on each side of the conveyor frame.
This fastens the two frame sections together at the correct
belt tension.
5. If it is necessary to add or remove conveyor links to achieve
the correct tension, OR if it is necessary to reverse the
conveyor belt for correct orientation, the belt will need to be
removed from the conveyor frame. If this is necessary,
perform the following procedure:
a. Remove the master links using long-nose pliers.
Then, roll up the belt along the length of the conveyor
frame.
b. Add or remove belt links as necessary to achieve the
correct belt tension.
c. Replace the belt on the conveyor frame. Check the
following:
•
The conveyor belt links must be oriented as shown
in Figure 2-9.
• The smooth side of the conveyor belt must face
UP.
d. Connect the inside master links. Check that the links
are oriented as shown in Figure 2-9.
e. Connect the outside master links. Note that the
outside master links each have an open hook on one
side. This hook aligns with the hooks along the sides
of the other conveyor links. See Figure 2-9.
