5. Remove the two ½ inch socket cap screws from their respective blocks. The screw and
rollers should come loose from the bottom of the channels. (
Illustrations 8.8 and 8.11
)
6.
If the bushing is still on the ½ inch screw, pull it off as well as the roller. Take careful note
to the orientation of the bearings in the rollers and how they are placed on the shafts.
7.
Place the new rollers (with bearings) onto the shafts as shown in
Illustration 8.14
. Place the
bushings back in place.
8. Carefully thread the shafts back into the blocks in the channels. The socket cap screws
should be turned enough to keep it fairly vertical and yet permit the block to be moved.
9. To properly set the rollers in position with the belts, follow the instructions in the
“
ADJUSTING THE PRESSURE BETWEEN THE COMPRESSION BELTS
”
page 32
.
8.5.4 TAKUP ROLLERS
The takeup rollers provide the tension in the compression belts. They also act as guides for the bag
tops as they begin to enter the compression process. After normal wear, the rollers and bearings
will need to be replaced. The replacement rollers come
with the bearings installed. (
Illustration 8.15
) When
replacing the rollers, always replace the front and rear
rollers at the same time. To replace the rollers, follow
these steps:
1. Turn “OFF” and lock out the electrical and
pneumatic supplies to the PBC machine.
2. Remove the fixed and swing channel shrouds. Also
remove the top cover closest to the drive motor.
3. To remove the takeup rollers, the tension in the
compression belt must first be removed. This is done
by turning the takeup block adjustment screw (
T
)
into the block. (
Illustration 8.15
) Do not turn the
screw too far into the block to the point where it
begins to tighten again.
4. Loosen the ½ inch socket cap screws (takeup block only). (
Illustration 8.15
) This is done from
the bottom of the rollers. Do not remove the screws.
5. Each takeup block is held in position by the four holding screws (
H
) on the bottom of the
channels. These screws pass through slots to allow for adjustments. Loosen the holding screws
(
H
), but do not remove them.
6. Remove the ½ inch socket cap screws from their respective blocks.
7. If the bushings are still on the screws, then remove them. (
