Application Notes
1.
NBC does not singulate products.
2.
Conveyor operations before and after NBC are vital to proper application decisions.
3.
The conveyor downstream from progressive release NBC must run at a speed which allows it
to receive products as fast as they are released from the NBC conveyor.
4.
There will not be a gap or means of detecting a specific product, directly on the end of NBC
without a downstream speed-up bed.
5.
When feeding sortation from NBC, use a split metering belt to singulate individual products
when specific minimum gap is required.
6.
NBC cannot be fed from an upstream conveyor at a rate exceeding the NBC rate, especially
from a curve.
7.
Convey all products along one side of NBC unless products are nearly the same width and
closely match the conveyor width. Skewing beds are available to accomplish this.
8.
During accumulation, product density (packing) increases with product weight and speed.
9.
For all applications, Nitta belt shall be used.
10.
Under no circumstances shall a mechanical lace be used with the Nitta blue urethane welded
belt TGW P/N 1205548.
11.
NBC conveyor requires a TGW Nitta Belt Welding Tool Kit for splicing the belt. This tool kit
was
developed by Nitta Corporation for TGW NBC belt requirements and are available only
from TGW.
12.
Limit the length of NBC conveyors to 300'. If you have a requirement beyond 300' contact
Applications Engineering.
13.
Always locate the drive bed at the charge end of the primary conveyor.
14.
Totes may have up to a 2" taper on each end without affecting the function of the electronic
sensors. Customers who have tapered totes may request TGW to perform a product test with
test
product supplied by the customer.
15.
All accumulation conveyors require a discharge brake zone up to 129 FPM unless discharging
to belt unit. For speeds at 130 FPM and above, a pivoting blade stop, blade stop, or brake belt
unit
is required.
16.
Due to the direct drive train, speeds may vary +/- 10% from stated speeds.
17.
The minimum bed length for all NBC Flat Belt drives is 8'.
18.
The 250-AT30 has an air take-up with a maximum belt take-up of 30", a maximum belt pull of
250 lbs. and is used for lengths from 12' to 1
0
0'.
19.
The 500-AT has an air take-up with a maximum belt take-up of 55", a maximum belt pull of
500 lbs. and is used for lengths from 12' up to 220'.
20.
Use the NBC Application Program to determine the drive style (250-AT30 or 500-AT) and
horsepower size based on rate and speed requirements.
21.
Take away speed to be equal or greater than NBC Flat Belt.
22.
Pricing includes: bed, end assembles, and belting.
23.
Floor supports are not included. See Support and Connections for details.
24.
Maximum amount of continuous skew is 12' not including maintenance skews.
