05Application solution

Merge, diverting & sorting

Bring multiple product streams together or route products into the right path. Well-designed flow control increases throughput, reduces intervention and downtime, and improves handling safety.

06One line, many possible paths

More productive and efficient, with less downtime.

Merge conveyors combine product streams in a processing line. Diverting and sorting conveyors route products using equipment selected for their weight, shape, required destination and available line capacity.

Merge solutions can combine two, three, four or more lines and singulate product for the next production stage. Depending on the product and application, control may be manual, motorized or pneumatic.

07Applications

Flow control across the production line.

The same core technologies support six connected handling functions, from accumulation and merging to a fully customized conveyor system.

01

Accumulation

Buffer products so upstream and downstream processes continue operating efficiently.

02

Diverting & sorting

Route products by attributes, destination or production-line capacity.

03

Merging

Consolidate multiple infeed lanes into a controlled single stream.

04

Product flow & control

Meter, gap and sequence products for the next operation.

05

Product handling

Protect stability and orientation while products change lanes or conveyors.

06

Custom conveyor systems

Combine standard and engineered components around a specific workflow.

08How merge conveyors work

Multiple lines become one controlled stream.

Merge conveyors combine two or more product lanes into a single line. The right approach depends on product geometry, stability, weight, rate and the required downstream sequence.

Automatic merging supports smooth, safe transport while reducing the manual intervention that can lead to stoppages and inconsistent product flow.

Inputs
Two, three, four or more lines
Output
One sequenced or singulated stream
Controls
Manual, motorized or pneumatic

09Source case records

Three merge challenges and their solutions.

These retained examples show how line rate, product stability and downstream equipment change the required merge design.

Case 01

Frozen pizzas: two lanes to one

A former process required an employee to intervene so frozen pizzas flowed smoothly. An automatic merge created smooth, safe transport, reducing downtime and improving productivity and efficiency.

ResultAutomatic two-to-one product flow
Case 02

High-speed parts: four lanes to one

Randomly spaced product left a cleaning and drying unit across four lanes at 40 parts per minute per lane. Sensors, servo motors and pacing conveyors gapped the product before four individual servo lanes merged it for an X-ray machine.

Result160 parts per minute after merging
Case 03

Small bottles: stable transfers

Flexible-chain mainline conveyors used a powered side guide at transfer points. A high-friction belt gripped each small plastic bottle to prevent tipping while it transferred from one conveyor to the next.

ResultControlled movement of unstable products

10Ways to merge

Select the mechanism around the product.

Each method solves a different combination of load, fragility, stability, speed control and lane-count requirements.

Product pusher merge conveyor
01 · Product pusher

Move loads into a centre conveyor.

Two infeed lines can transfer products onto a centre conveyor in front of a pusher. Source applications include heavy-duty products weighing up to 500 lb / 226.8 kg.

Powered side-guide merge conveyor
02 · Powered side guide

Assist a controlled side transfer.

Useful for heavy products requiring transfer assistance, delicate products that should not rub against a static guide, and precision applications requiring better speed control. It can also pull a gap between products.

Pneumatic gate merge conveyor
03 · Pneumatic gate

Release one line while another accumulates.

Gates at the merge point open or close, allowing one line through while product waits behind a closed gate on the other line.

Pneumatic product squeezer on a merge line
04 · Pneumatic squeezer

Hold round products without a gate.

Pneumatic squeezers hold rolls in place on one infeed, allowing that side to accumulate until the products are released.

Multi-line conveyor merge arrangement
05 · Multi-line merge

2-to-1, 3-to-1, 4-to-1 and beyond.

Custom merge systems can support five-to-one or six-to-one flow when required. A four-to-one packaging merge may combine sanitary conveyors, servo motors and photo eyes for fast, consistent throughput. Stainless-steel washdown construction supports sanitation and food safety where the application requires it.

11Diverting & sorting

Route by product attributes or line capacity.

Conveyor diverters and sorting conveyors handle products according to characteristics such as weight and shape, as well as the capacity and destination of each line.

Simple static guides and plows or dynamic gates and paddles can be added to a base conveyor. For modular applications that do not require complex control, a divert arm may provide an effective solution. Powered transfers maintain speed through the transfer, while retracting tails can extend or retract to perform several flow-control functions.

Diverting system layout
01

Diverters & gates

Static guides, plows, dynamic gates and paddles change product direction to one or multiple locations and meter flow into specific areas.

  • Separate by selected attributes
  • Use proximity switches, photo eyes or counters
  • Pneumatic or electric motion
02

Pushers

Side-mounted or overhead pushers are selected according to product and stroke length, moving products perpendicular to conveyor flow.

  • Remove or transfer parts
  • Feed other conveyors or equipment
  • Create horizontal product stacks
  • Sensor or counter control
03

Lane guiding

Guides create multiple product lanes across the width of a conveyor belt and control how products move between them.

  • Accumulate large quantities
  • Divert across lanes
  • Merge lanes into one
  • Support unstable products

12Custom system support

From production need to operating line.

A standard conveyor can be modified or combined into a fully custom merge, diverting and sorting system. Project scope should cover analysis, design, installation, training and long-term care.

01

Needs analysis

Define product, throughput, route, interface and operating requirements before the concept is selected.

02

CAD modelling

Develop the layout and check conveyor relationships, transfers, access and available space.

03

Mechanical design

Engineer the structure, controls and handling components around the application.

04

Installation

Plan delivery, staging, setup and debugging so the equipment starts efficiently and performs as intended.

05

Training

Prepare operators to use the merge, diverting or sorting equipment comfortably and efficiently.

06

Maintenance

Inspect belts, pulleys, bearings, drive trains, gearmotors and accessories; maintain tracking, tension and lubrication.

Project-specific terms

Installation, training, maintenance scope, fees, replacement parts and commercial terms are confirmed in the Roarer project proposal.
