Warnings & Safety Instructions
Failure to follow the instructions, warnings, cautions (throughout this booklet) and warning
labels (on the conveyor) may result in injury to personnel or damage to the equipment.
Your TGW Systems NBS Narrow Belt Sorter is powered by a motor and can be stopped only by turning
off electrical power to the motor. As with all powered machinery, the drive and driven sprockets,
chains, and pneumatically actuated devices present a danger. We have installed or provided guards to
prevent inadvertent contact with these components along with warning labels to identify the hazards.
After maintenance, REPLACE guards immediately. Keep ALL warning labels clean and clear of
any obstructions.
Be sure to read and heed all Warnings. Warnings and Cautions are included throughout this manual
and are defined as follows:
Warning ---- A notice which, if not followed, could
result in serious injury to personnel.
Caution ---- A notice which, if not followed, could
result in damage to equipment.
A thorough understanding and compliance with these Warnings and Cautions will greatly reduce the
possibility of personnel injury or equipment damage.
Never remove, deface or paint over any labels. Any damaged label will be replaced by TGW Systems
Inc. at no cost by contacting the Distributor Services Department.
WARNING
Do not perform maintenance on the conveyor until the start-up controls are locked out and cannot be
turned on by any person other than the one performing the maintenance. If more than one member of
a crew is working on the conveyor, EACH CREW MEMBER MUST HAVE A LOCK ON THE POWER
LOCK OUT. The air pressure must be turned off to the work area. All pneumatic devices must be de-
energized to prevent accidental cycling of the device.
Make sure personnel are clear of all conveyor equipment before restarting the system.
It is very important to instruct personnel in proper conveyor use including the location and function of all
controls. It is important to establish work procedures and access areas which do not require any part of
a person to be under the conveyor. It should be required that long hair is covered by caps or hair nets
and the wearing of loose clothing or jewelry when working at or near the conveyor be prohibited.
Maintain enough clearance on each side of the unit for safe adjustment and maintenance of
components. Provide crossovers at sufficient intervals to eliminate the temptation to climb over or
under any conveyor. Prohibit riding or walking on conveyor by anyone.

NBS SP Application
NBS SP SELECTION GUIDELINES
Use NBS SP When:
•Higher speed sortation then NBS is required
•Product may be same size and weight, or mixed
•Product weight: 1-20 lbs, 1000 lbs. total load
•Product size: 4" X 4" Min. -- 13" X 24" Max.
•Ambient temperature is +35° to 100°F
APPLICATION NOTES
1. Matching conveyor rates before and after NBS sortation are vital to proper application decisions.
2. 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.
3. 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)
4. Induction to NBS-SP sortation must be able to singulate individual products with a minimum gap of 6"+
conveyor width at 250 FPM 10"+ conveyor with at 300 FPM.
5. Justify all products along the exit lane side of the NBS SP sortation for single direction transfers.
6. When NBS-SP over-all-length is over 50' and up to 100' in length, an addition auxiliary air take-up is
required.
7. The maximum length of a NBS SP sortation conveyor, including two air take-up units, is 100'.
8. The gearmotors used for NBS SP drives are all VFD (variable frequency drive) rated.
CAUTION
The use of a VFD or at least a "soft start" motor drive is recommended for NBS SP drive motor control.
Ignoring this point may void the motor warranty.
GENERAL CONSIDERATIONS
ELEVATION (TOB)
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.
TRANSFER LOCATIONS
•The leading edge of the first transfer module must be a minimum of 28" from the charge end of the
sorter.
•The trailing edge of the last divert module must be at least 42" from the discharge end.
•The center line of a transfer exit lane is centered on the center line of the transfer rollers in an NBS
SP.
•Standard available coated transfer rollers widths are: 9", 12", 15", 18", & 21"
•One NBS SP transfer can transfer to up to four separate lanes of 1/2 the width of the roller length.
•Single direction transfer to two lanes is called a "Dual Transfer"

Receiving & Site Preparation
GENERAL
TGW Systems NBS Narrow Belt Sorters are shipped in subassemblies. These subassemblies are
packaged to guard against damage in shipment, when handled properly.
Examination immediately following unloading will show if any damage was caused during shipment. If
damage is evident, claims for recovery of expenses to repair damage or replace components must be
made against the carrier immediately. While unloading, a check must be made against the Bill of
Lading, or other packing lists provided, to confirm full receipt of listed items.
CAUTION
TAKE CARE DURING THE REMOVAL OF EQUIPMENT FROM THE CARRIER. Remove small items
and boxes first. Pull and lift only on the skid, not on the frame, crossmember or any part of the
equipment. Be sure the skid is free of other materials which may be on top of or against the side of the
skid to be removed.
PREPARATION OF SITE
After the conveyor is received, move it to the
installation site or designated dry storage area as soon
as possible. Clean up all packing material immediately
before parts get lost in it. Loose parts should remain
in the shipping boxes until needed.
Prior to starting assembly of the conveyor, carefully
check the installation path to be sure there are no
obstructions that will cause interference. Check for access along the path needed to bring in bed
sections and components closest to the point where they are needed. It is often necessary to give the
area along the system path a general cleanup to improve installation efficiency, access and accuracy.
PARTS INVENTORY & IDENTIFICATION
Each subassembly is shipped completely assembled except the bed joint splice plate/nuts which are
shipped with other loose parts. Identify and separate the sorter subassemblies by type or tag number,
for inventory and ease of locating during installation.
An identification label is attached to the inside of one side channel or on a crossmember, close to one
end of each conveyor bed. This label contains: job number, part number, order number, tag number (if
specified), assembler's initials and date of manufacture. On supports, the tag is located on the bottom
side of the foot. On special devices it is located on a convenient flat surface that is not offensive to the
appearance of the equipment but is still accessible for
viewing. These numbers can be cross-referenced against
the packing list. The illustrations in this manual and the part
number stickers will assist you with your inventory.
Identification Label

NBS90-SP IOM
13
NBS90-SP Rev010512
Loose parts are boxed and shipped separately. You should have all conveyor sections and supports
for a particular conveyor prior to installation. It is cost-effective to identify and procure any missing
parts before they are needed for assembly. Small items like nuts and bolts are weigh-counted and
packaged by size and type.
CAUTION
Do not remove finishing nails from rail ends. They keep the UHMW guides from sliding down to the
discharge end.

NBS90-SP IOM

NBS90-SP Rev010512
General Procedures
The following procedures are to be used as guidelines only. Specific installation methods will vary
somewhat depending on available equipment on site and each installer's preferences based on past
experience.
WARNING
The Installation Supervisor must be experienced with conveyor and qualified in the mechanics of the
equipment and enforce safe working procedures for the protection of the crew, customer, and
customer's property.
DIMENSIONAL REFERENCE POINTS
The path of each conveyor in the system is determined by establishing a reference point at each end.
The center line of the conveyor is established and a chalk line is snapped between these points.
Conveyors should be installed with the center line of the bed matching the center line of the conveyor
path. Locate and mark the center of the crossmembers at each end of the conveyor. Use a plumb line
or other acceptable means to ensure accuracy to the chalk line.
Always carry out a thorough check for any obstructions such as building columns, manholes, etc. It
may be necessary to reroute the conveyor to avoid the obstruction. In this case it would be advisable
to begin installation at this point, using the obstruction as a reference point (Datum), and install the
sections in either direction as required.
All conveyor sections must be checked for squareness prior to installation as "racking" or being
knocked out of square may have occurred during shipping and handling.
ELEVATIONS
All top-of-belt (TOB) heights should be installed in accordance with the elevations shown on the
drawings. In addition, all sortation devices must be level across both the frame width and length.
Leveling of the frames is best done using a rotating laser level along the length of the conveyor and a
builder's level across the width.
After the first elevation is established at a critical point, the elevation of all other points shall be relative
to this first point. Normal practice is to dimension the layout and measure elevations from the floor at
each point of support.
As the conveyor system proceeds onto another floor or into another building or room, a new elevation
will be measured from the floor at that point. This new elevation will then become the reference for
subsequent elevations.
When installing an overhead system, the first elevation is measured from the floor and becomes the
reference elevation point until a change in elevation is shown on the layout. Any new elevation is also
measured from the floor and becomes the new reference point. The process is repeated each time an
elevation change occurs.
CAUTION

NBS90-SP IOM
15
NBS90-SP Rev010512
Consult the building architect or a structural engineer regarding ceiling loading or structural limitations of the
building if any conveyor is ceiling hung.
COMPONENT ORIENTATION
Using your conveyor system layout drawing and the numbers on the I.D. tags on each component,
position and orient the conveyor sections. You must know:
•The direction of product flow
•The elevation height
•The drive is positioned at the discharge end
•The end pulley is positioned at the charge end
IMPORTANT! Do not make alterations to the equipment without consulting with user's representative
and TGW Systems. Unauthorized modifications to the equipment may impair its function, create a
hazardous condition, affect its useful life and/or void the warranty.

NBS90-SP Rev010512
Supporting Arrangements
FLOOR SUPPORTS
Install bolts used to attach the standhead to the frame
so the nut is on the bottom. Standhead bolts should be
left finger tight while the conveyor is being assembled
and aligned.
Floor supports are ordered by nominal height range,
which is the dimension from the floor to top of the
support. Conveyor elevations are shown on the layout
by top-of-belt elevations. The difference between top of
belt (TOB) and top of support is 7-5/8". This dimension
must be subtracted from the TOB height to set support height.
It is important that conveyor frames be installed level. Floor supports will accommodate normal
irregularities in the floor surface. Adjustment for elevation in floor supports is accomplished with metal-
on-metal bolt clamping force. To achieve the support's stated load rating, it is necessary to tighten the
elevation adjustment bolts (3/8" diameter) to 23 ft./lbs. of torque.
Supports should always be installed in the vertical position, and any variations due to conveyor pitch or
floor slope will be compensated for in the pivoting standhead of the support.
ANCHORING
Anchoring in concrete floors is accomplished by drilling into the floor and inserting the suitable anchor
bolt. The hole diameter and depth must be in accordance with the anchor bolt manufacturer's
instructions.
Anchor intermediate floor supports with two anchor bolts, one through each support foot plate using at
a minimum 3/8" diameter anchor bolts. For floor supports over 5' high or when supporting drives, use
1/2" diameter anchor bolts.
Stagger anchors from front hole on one side of the support, to rear hole on opposite side. Anchor bolts
for equipment subject to impact loads should be a minimum of 1/2" in diameter.
WARNING
Place a bolt through the frame and support immediately with finger tight nut. This will prevent the frame
from falling off the support, if bumped, and causing injury.

NBS90-SP IOM
17
NBS90-SP Rev010512
BED/SUPPORT CONNECTORS
NBS can only be supported at bed joins. Adjoining beds are connected using 3/8” thick by 10” nut
plate, 3/16” thick by 10” clamping plate and 3/8” hardware. These parts are shipped with other loose
parts. Insert 10” nut plate halfway into the formed channel end of each bed. Then mount standhead
support with two 3/8-16 X 1” hex head bolts with flat and lock washers. After that mount 10” clamp plate
to channel ends with four 3/8-16 X 1” hex head bolts with nut, flat and lock washers (see picture below).
It can be seen that a crossmember could be moved into the recessed area of the standhead support
bracket if needed.
Maintaining the rigidity and flatness of the conveying surface is the end result of proper support
installation.
ALUMINUM EXTRUSION T-NUT CONNECTORS
The aluminum extrusions that hold the UHMW belt guides are installed at the factory with tee bolts up
through their mounting crossmembers. The placement of these extrusions is gauged precisely (2-5/16"
center-to center) so that the triple T-nut connectors between the extrusions line up at installation. The
triple T-nut connectors are mounted, at the factory, flush with the ends of the aluminum extrusions on
the discharge side of all NBS bed assemblies. These triple nut connectors should be extended half-
way out of the extrusions before "plugging in" the next bed downstream during installation. After all bed
components are installed, leveled and straightened the 5/16-18 hex head bolts used in the triple T-nut
connectors should all be loosened, to straighten the aluminum extrusion joints and re-tightened.

Belt Installation
PRE-INSTALLATION
Belts, as shipped from TGW Systems, are cut to length
with lacing installed. Rolls of belting should be stored on
edge on a pallet (see belt below). Never leave a belt
where it may absorb moisture. Remove any tight shipping
banding immediately upon arrival. Lacing pins are taped
inside the lacing on each belt.
The NBS90-SP conveyor should be completely installed
and aligned before belt installation.
Remove the plexiglass side covers from the sides of the
auxiliary belt take-up frame, exposing the take-up pulleys.
Switch the take-up air switch to the un-tensioned position,
raising the take-up pulleys to the minimum take-up position. Then remove or slide covers between the
aluminum belt track extrusions so that the belt guide wheels are exposed. Do the same for each NBS
30 diverter and the charge end pulley.
Remove the o-ring from the o-ring driven gap roller.
BELT THREADING
Because NBS uses multiple narrow belts of long length, it
will be most efficient to have two people working together
during the threading process.
The belting must be uncoiled and laid out flat on the
sorter, with the smooth black carrying surface up. The
belts must not be allowed to twist along their length as
they are installed. Start at the charge end (farthest from the drive) and feed all of the belts through
together at the same time. Start the belts down between the gap roller and the end pulley. Guide the
belts under the 5" diameter end pulley and up and over the 4" diameter snub pulley, before passing
through the belt guide wheels.
All belts must pass over any return rollers positioned to minimize belt sag and through holes in crossmembers.
NBS90-SP divert rollers fit up between the narrow belts.
The black PVC surface of the belt should be up and the rough surface rides in the UHMW tracks.
Mesh the loops of the lacing on one end of the belt with the loops on the other, so the sides of the belt are even,
and install the lacing pin.
Because the different width sorters have different numbers of belts, the air pressure to properly tension the belts
is different for each width.

NBS90-SP IOM
19
NBS90-SP Rev010512
BELT TRACKING
With the belts tensioned, "bump" the motor to be sure rotation is correct, the belts are running smoothly
and maintaining their position. Most NBS90-SP conveyors do not require belt tracking. However,
each conveyor should be checked at the charge and discharge ends to be sure the belts are floating in
a neutral position not crowding the sides of the UHMW guide tracks. If the belts are out of their grooves
or riding hard to one side adjustment can be made on the driven pulley jackscrew, at the discharge end,
or the snubber roller in the end pulley assembly at the charge end, to realign them.
Reinstall the bottom pan on the end pulley assembly and access covers on the auxiliary belt take-up.
