A narrow belt sorter moves product on several parallel narrow belts and diverts each item with pop-up rollers or wheels that rise between the belts. Set at 30 or 90 degrees and able to divert to either side, it sorts small to medium cartons in up to 75 percent less floor space than other sorters.

Narrow belt sorter at a glance

A narrow belt sorter, sometimes called an activated roller belt sorter, transports product across multiple parallel narrow belts. At each divert point, pop-up rollers or wheels rise between the belts and push the item off to the side. A 30 degree divert keeps product orientation and pulls minimal gaps for higher throughput, while a 90 degree divert transfers product straight off either side into a spur or workstation. The design is compact and cost-effective, using up to 75 percent less space than other sorters with close divert centers, which makes it a fit for small to medium cartons rather than large or fragile loads. Hytrol builds this as the ProSort MRT line, and HOJ integrates it to your product size and rate.

How does a narrow belt sorter work?

A narrow belt sorter runs several narrow belts side by side with gaps between them. Product rides on top of the belts, tracked by sensors to its assigned destination. At that point, a bank of powered rollers (90 degree) or angled wheels (30 degree) pops up through the gaps between the belts, lifts the item slightly, and drives it off the side of the conveyor onto a takeaway spur. Because the diverter sits between the belts and only rises when needed, divert points can be placed close together, and the sorter transfers to either one or both sides. The 30 degree version maintains the product's orientation and creates minimal gaps, which raises throughput for small cartons.

Where are narrow belt sorters used?

Order fulfillment. Diverting small to medium cartons to pack lanes in tight floor space.

Two-sided sortation. Transferring product off both sides into spurs or workstations.

Value-added stations. Routing items to ticketing, quality control, and packing positions.

Space-constrained lines. Fitting close divert centers where larger sorters will not.

Cost-sensitive operations. Sorting cartons at mid rate without a high-speed sorter's cost.

How is a narrow belt sorter different from a sliding shoe sorter?

Both are linear sorters that divert product off a straight conveyor, but they suit different product and budget. A narrow belt sorter uses pop-up rollers or wheels between parallel belts to divert small to medium cartons in a compact, lower-cost footprint at mid rate. A sliding shoe sorter slides guided shoes across slats to push product off with a gentle positive divert at higher speed, handling mixed sizes and more fragile or larger cases. Choose a narrow belt sorter for small to medium cartons, two-sided transfer, and tight space at lower cost. C

A pop-up wheel sorter, also called a belted pivot wheel sorter, diverts product with angled wheels that pivot to push totes and boxes off a powered belt. It sorts up to 90 items per minute at belt speeds to 300 feet per minute, and one drive can power many diverts, making it the lowest-cost linear sorter.

Pop-up wheel sorter at a glance

A pop-up wheel sorter moves product on a powered belt past divert stations fitted with angled wheels. At each station the wheels pivot to drive a tote or box off the line at a 30 degree angle, to the left, right, or both sides, while keeping the product's orientation. In the modern belted pivot wheel design, the wheels sit at the same height as the infeed and exit belts and only pivot, which reduces missed diverts compared with older units that raised whole wheel beds. The defining advantage is cost: a single drive can power many divert stations, often up to a dozen, and takeaway spurs can be slave driven, so a pivot wheel sorter typically runs about half the cost of a sliding shoe sorter. Hytrol builds this as the ProSort SC, and HOJ integrates it for tote and box sortation.

How does a pop-up wheel sorter work?

A pop-up wheel sorter conveys product on a belt that tracks each item to its assigned divert station. At that station, a bank of angled wheels pivots into contact with the product and drives it off the side of the conveyor onto a takeaway spur. The wheels turn at an angle to the belt, so they push the tote or box diagonally while it keeps moving forward, which maintains orientation through the divert. Because the wheel banks are slave driven from the main conveyor, one drive motor can run several divert points in sequence, and the after-sort spurs can be gravity skatewheel or powered. That shared-drive design is what keeps the cost per divert low.

Where are pop-up wheel sorters used?

Tote and box sortation. Diverting totes and flat-bottomed boxes to lanes or workstations.

Lower-rate fulfillment. Sorting at up to 90 per minute where high speed is not required.

Cost-sensitive lines. Powering many diverts from one drive to hold down system cost.

Multi-divert layouts. Placing several close divert points along a single conveyor.

Order routing. Sending totes to pick, pack, or replenishment zones.

How is a pop-up wheel sorter different from sliding shoe and narrow belt sorters?

All three are linear sorters, but they separate by rate, product, and cost. A pop-up wheel sorter is the lowest-cost option, diverting totes and boxes at up to 90 per minute with one drive powering many diverts, ideal where rate is modest and budget matters. A narrow belt sorter uses pop-up rollers between parallel belts for small to medium cartons in a compact footprint at mid rate. A sliding shoe sorter slides shoes across slats for a gentle positive divert at high speed with mixed and larger product. Choose pop-up wheel for totes and boxes at lower cost, narrow belt for small cartons in tight space, and sliding shoe for high rate and mixed product.
