NBS 90 Transfer Roller Adjustment Procedure
NBS 90 transfers are assembled as a stand alone unit that is inserted into an NBS bed section. The height of the
roller is set by the use of a setting gauge, and adjustment is performed at each of the four corners of the unit on
the assembly bench. When the unit is inserted into the bed and secured into place, the roller heights are within
our assembly tolerance of +/- 1/32”. Depending upon the speed of the sorter, weight of the product, and condition
of the transferred product’s bottom surface, slight adjustments of the transfer rollers’ heights may be necessary to
effectively transfer these products.
Adjustment in the field is performed by the following steps:
1.
Determine which corners need height adjustments. This can be determined by placing a straight edge across
the sorter belts and measuring the distance from the bottom of the straight edge to the top-of-roller at each
transfer corner. If the transfer rollers can be forced into their up position, the straight edge can be placed on
the roller surfaces and the measurements can be made down to the belt surfaces. (The roller mounting forks
are usually in their full up adjusted position, and lowering the roller height is usually the easiest way to
adjust.)
2. Remove the two flat orange end guards from both ends of the transfer (this will allow access to the four
adjustment locations).
3. The roller mounting forks have 3/4’ long slots in their faces and are clamped between the jack bolt angle and
the longitudinal crossmember that separates the two forks.
4. Loosen the two hex head cap screws in the corner that is being adjusted as well as the jam nuts on the jack
screw. Use the jack screw jam nut that moves the fork in the direction necessary. Repeat this procedure on
each corner that needs adjustment.
5. When transfer roller are all parallel to the sorter belt surfaces, tighten all fasteners and replace the guards.
