Belt Conveyors
Use a continuous belt supported by rollers, slider beds, or other structures to move packages, parts, bulk materials, and manufactured products.
RES / CONV — MATERIAL TRANSPORT REFERENCE
Conveyor Systems.
Conveyor systems transport products, components, packages, pallets, containers, bulk materials, workpieces, and process loads between manufacturing, assembly, packaging, storage, inspection, and distribution operations. Systems may use belts, rollers, chains, screws, overhead carriers, buckets, platforms, pneumatic transport, or gravity depending on the material and required movement. Selection depends on product dimensions, weight, orientation, throughput, speed, route, incline, elevation change, accumulation, transfer points, drive requirements, belt or chain construction, frame design, controls, sensors, guarding, environmental conditions, cleaning requirements, maintenance access, and integration with upstream and downstream equipment.
OPERATING PRINCIPLE
Conveyors create a controlled path for material movement.
A conveyor supports or contains a product while a moving belt, roller, chain, screw, carrier, airflow stream, gravity force, or other mechanism advances the load along a defined route.
Powered systems commonly use electric motors, gear reducers, sprockets, pulleys, shafts, couplings, bearings, and variable-speed drives. Sensors and controls can synchronize product flow, create accumulation zones, trigger sorting, stop jams, and coordinate transfers.
Conveyor design must consider the complete material path rather than only the straight sections. Loading, discharge, transfers, curves, inclines, accumulation, merges, diverts, elevation changes, operator access, guarding, and maintenance frequently determine overall system performance.
BASIC CONVEYOR IDENTIFICATION
Load
Product weight, dimensions, shape, center of gravity, and distribution.
Speed
Linear rate at which the conveyor transports product or material.
Throughput
Quantity of material or number of units moved during a defined period.
Accumulation
Temporary storage of product on the conveyor while controlling downstream flow.
Transfer
Point where product moves from one conveyor, machine, or transport surface to another.
Drive
Motor, reducer, pulley, sprocket, shaft, or other mechanism producing conveyor movement.
SECTION / 01
Common Conveyor Types
Conveyor architecture is selected according to the product or material, transport route, required orientation, elevation, accumulation, process environment, and throughput.
Roller Conveyors
Move products across a series of rollers using gravity or powered drive mechanisms. Common loads include cartons, totes, pallets, containers, and rigid products.
Chain Conveyors
Use one or more chains to transport pallets, fixtures, heavy products, assemblies, and loads requiring durable positive engagement.
Screw Conveyors
Rotate a helical screw inside a trough or tube to move powders, granules, grains, sludge, and other bulk materials.
Overhead Conveyors
Carry suspended products above the floor and are often used through paint, coating, curing, assembly, finishing, and production processes.
Vertical Conveyors
Lift materials between different elevations using platforms, continuous carriers, buckets, spirals, or vertical lift mechanisms.
Modular Belt Conveyors
Use interlocking belt modules that can support curves, drainage, washdown, specialized surfaces, and configurable product handling.
Gravity Conveyors
Use product weight and slope rather than a powered drive to move suitable loads along rollers, wheels, or chutes.
Pneumatic Conveyors
Transport powders and bulk solids through enclosed piping using controlled airflow, pressure, or vacuum.
SYSTEM / MATERIAL PATH
Product behavior determines conveyor architecture.
The same conveyor type can perform very differently depending on product geometry, spacing, orientation, center of gravity, friction, contamination, and transfer requirements.
CONVEYOR SYSTEM CHECKPOINTS
Product
Record dimensions, weight, shape,
material, surface condition,
rigidity, stability, temperature,
and center of gravity.
Route
Define length, width, curves,
incline, decline, elevation changes,
floor constraints, and required clearances.
Throughput
Establish units per minute,
mass flow, peak demand,
spacing, accumulation,
surge conditions, and buffer requirements.
Transfers
Evaluate gaps, nose bars,
dead plates, rollers,
side transfers, lifts,
pushers, merges, diverts,
and product stability.
Drive
Size motor, gearbox, belt,
chain, pulley, sprocket,
shaft, brake, and variable-speed control.
Controls
Coordinate sensors, PLC logic,
zones, accumulation,
machine handshakes, alarms,
jam detection, and emergency stops.
Safety
Address guarding, pinch points,
rotating components, access,
crossings, emergency stops,
lockout, and maintenance procedures.
SECTION / 02
Load, Speed, Accumulation & Transfers
Conveyor performance depends on moving the required load at the required rate without creating unstable transfers, excessive wear, jams, or unsafe conditions.
Load Capacity
Frames, rollers, belts, chains, bearings, shafts, drives, and supports must carry both individual and accumulated loads.
Conveyor Speed
Speed influences throughput, product spacing, transfer stability, motor demand, control timing, wear, and operator interaction.
Accumulation
Accumulation zones allow product to buffer when downstream equipment stops or operates at a different rate.
Transfers
Small or unstable products can require carefully designed transfer geometry to prevent tipping, catching, rotating, or falling between conveyors.
SECTION / 03
Conveyor System Specifications
Conveyor replacement and integration require mechanical, electrical, material-handling, environmental, safety, and control specifications to be reviewed together.
Specification
What to Verify
Why It Matters
Load
Unit weight, total accumulated load,
dimensions, orientation,
center of gravity, and impact.
Determines frame, roller, belt,
chain, drive, and support requirements.
Width / Length
Conveyor width, usable product width,
overall length, elevation,
curves, and mounting envelope.
Geometry must fit the facility
and safely support the product.
Speed
Nominal speed, adjustable range,
acceleration, deceleration,
indexing, and synchronization.
Speed affects throughput,
controls, product stability,
and downstream machine timing.
Belt / Chain
Material, width, pitch,
surface, cleats, tracking,
tension, strength, and temperature rating.
Conveying surface must suit the load,
process, friction, environment,
and cleaning requirements.
Drive
Motor power, voltage,
gearbox ratio, pulley or sprocket,
shaft size, brake, and VFD.
Drive system must overcome friction,
incline, acceleration,
accumulated load, and duty.
Controls
Sensors, PLC I/O, zones,
variable speed, machine interface,
jam detection, alarms,
and communication protocols.
Controls determine how the conveyor
behaves within the larger production system.
Environment
Dust, moisture, oil,
chemicals, food contact,
washdown, temperature,
vibration, and outdoor exposure.
Environment influences materials,
lubrication, bearings,
motors, enclosures, and sanitation.
Safety
Guards, pinch points,
emergency stops, crossings,
access, lockout,
signage, and maintenance procedures.
Conveyor motion creates hazards
that must be addressed throughout
operation and maintenance.
Maintenance
Belt tracking, chain tension,
lubrication, bearings,
wear parts, cleaning,
inspection points, and access.
Maintainability strongly affects
uptime and long-term operating cost.
SECTION / 04
Conveyor System Selection
Start with the product and required movement, then define route, throughput, conveyor type, drive, controls, environment, safety, and maintenance requirements.
01
Define the Load
Record product dimensions, weight,
shape, orientation, stability,
temperature, surface condition,
bulk density, flowability,
or other handling characteristics.
02
Define the Route
Establish pickup and discharge points,
total travel distance, curves,
incline, decline, elevation,
floor space, overhead space,
crossings, and machine interfaces.
03
Determine Throughput
Calculate normal and peak material flow,
product spacing, line speed,
accumulation, surge capacity,
buffer requirements, cycle rate,
and downstream demand.
04
Choose Conveyor Type
Select belt, roller, chain,
screw, overhead, vertical,
modular, gravity, pneumatic,
or a combination based on
the load and process.
05
Design Drive & Controls
Size motors and gearboxes,
establish speed control,
select sensors, accumulation logic,
PLC interfaces, interlocks,
jam detection, sorting,
and machine handshakes.
06
Validate Safety & Service
Confirm guarding, emergency stops,
access, sanitation, cleaning,
maintenance clearance, lubrication,
wear-part replacement, lockout,
environmental conditions,
and operating procedures.
Compatibility / Note 22
Matching conveyor width and speed does not make two conveyor sections interchangeable.
Conveyor sections with the same nominal width can differ in frame height, roller centers, belt construction, chain pitch, pulley diameter, sprocket size, shaft dimensions, motor voltage, gearbox ratio, speed range, load capacity, mounting points, elevation, transfer geometry, sensor locations, control voltage, network interface, guarding, accumulation logic, environmental rating, and product handling behavior. A small change in transfer height or gap can also affect product stability. Verify the complete mechanical and control specification before substitution. See the Automation & Motion Systems Reference, Material Handling Systems, and Component Compatibility Guide.
