material is moved against gravity by a conveyor. |
| NIP POINT GUARD:
A guard placed to eliminate points or areas on the conveyor
where injuries might occur. |
| NOSE
ROLLER: A small roller, used on power belt curve
conveyors, to reduce the gap at the transfer points. |
| NOSEOVER:
A section of conveyor with transition rollers placed
in conveyor to provide transition from incline to horizontal
or horizontal to incline. |

| 0-RING:
Polyurethane bands polyurethane used to transmit drive power
from roller to roller or spool to roller. (138-SP, 190-SP) |
| OVERALL LENGTH:
(OAL) The dimension outside of pulley to outside of pulley including
belting or lagging, of any conveyor lengthwise. |
| OVERALL WIDTH:
(OAW) The dimension outside to outside of frame rails. |
| OVERHEAD DRIVE:
A drive assembly mounted over a conveyor, which allows clearance
for the product. |
|
| P |
|
| PACKAGE STOP: Any
of various devices, either manual or mechanical, used to stop
flow on a conveyor. |
| PARTS CONVEYOR:
A conveyor used to catch and transport small parts, stampings,
or scrap away from production machinery to hoppers, drums, or
other operations. (PC, PCA, PCX, PCH) |
| PHOTO
CELL: Electrical device used to sense product
location. |
| PIVOT PLATE:
The gusset that attaches the conveyor to the support leg. |
| PLASTISOL COATING:
Poly-vinyl chloride (PVC) covering for roller
tubes to prevent product damage or marking. Usually (#70 durometer)
green or (#90 durometer) red in color. |
| PLOW:
A device positioned across the path of a conveyor at the correct
angle to discharge or deflect objects. |
| POLY-TIER
SUPPORT: Supporting members capable of supporting
more than one level of conveyor at a time. Each tier has vertical
adjustment for leveling the conveyor. |
| POP-OUT ROLLER:
A roller, normally placed on the ends of a belt conveyor used
to aid in transfer, and set in a wide groove to allow it to
eject if an object comes between it and the belt. |
| PORTABLE
CONVEYOR: Any type of transportable conveyor,
usually having supports which provide mobility. |
| PORTABLE SUPPORT:
Supporting members that provide conveyor mobility by use of
casters or wheels. |
| POSITIVE CROWNED
PULLEY: A pulley that tapers equally from both
ends toward the center, the diameter being the greatest at the
center. The crown aids in belt tracking. |
| POWER
BELT CURVE: A curve conveyor that utilizes a
belt, driven by tapered pulleys. |
| POWER
CONVEYOR: Any type of conveyor that requires
power to move its load. |
| POWERED
FEEDER: A driven length of belt conveyor, normally
used to move product horizontally onto an incline conveyor |
| PRESSURE
ROLLER: A roller used for holding the driving
belt in contact with the load carrying rollers in a belt driven
live roller conveyor. |
| PRODUCT
FOOTPRINT: The surface of the product that comes
in contact with the belt rollers, or wheels of the conveyor. |
| PROXIMITY SWITCH:
An electrical device to control some function of a powered conveyor. |
| PULLEY:
A wheel, usually cylindrical, but polygonal in cross section
with its center bored for mounting on a shaft. |
| PUSH BUTTON STATION:
An electrical device that operates a magnetic
starter |
| PUSHER:
A device, normally air powered, for diverting product from one
conveyor line to another line, chute, etc. |
|
| R |
|
| RACK:
As in a curve, to bend the frame racks down in order that the
discharge elevation is lower than the infeed elevation. |
| RECEIVING END:
The end of a conveyor from which the products move toward you. |
| RETURN
IDLER: A roller that supports the return run
of the belt. |
| REVERSIBLE:
A conveyor that is designed to move product in either direction. |
| ROLLER:
A round part free to revolve about its outer surface. The face
may be straight, tapered or crowned. Rollers may also serve
as the rolling support for the load being conveyed. |
| ROLLER
BED: A series of rollers used to support a conveying
medium. (ex: Belt) |
| ROLLER
CENTERS: The distance measured along the carrying
run of a conveyor from the center of one roller to the center
of the next roller. |
| ROLLER
CONVEYOR: A series of rollers supported in a
frame over which objects are advanced manually, by gravity or
by power. |
