NBS90 SP Applications
•
Matching conveyor rates before and after NBS sortation are vital to proper application decisions.
•
The transfer exit lanes from NBS SP can be gravity roller (used as a deceleration area), chutes
or powered conveyor run at a speed which allows the lane to receive products as fast as they
are transferred.
•
The maximum divert rate for a NBS SP single-direction is 120 CPM. The bidirectional rate is
120 CPM. (Contact the Customer Support group for application consideration above these
rates)
•
Induction to NBS-SP sortation must be able to singulate individual products. Minimum gap of
6"+ conveyor width at 250 FPM 10"+ conveyor with at 300 FPM.
•
Justify all products along the exit lane side of the NBS SP sortation for single direction transfers.
•
When NBS-SP over-all-length is over 50' and up to 100' in length, an addition auxiliary air take-
up is required.
•
The maximum length of a NBS SP sortation conveyor, including two air take-up units, is 100'.
•
All units require 1/2” gap before and after the unit for maintenance access to the end covers.
NBS SP ELEVATION TOP OF BELT
The minimum elevation at the discharge end of an NBS SP sortation line is 23". The end drive unit is
located at the discharge end and requires a space 23" high by 33" long.
Extra room alongside the drive should be provided to allow maintenance personnel access to either
side of the drive assembly. In order to remove air take-up from bottom side of conveyor, add 6” of
clearance and 7” for transfers.
