Forward-Reverse Sorting Scales

These compact dynamic sorting scales use the weighing belt itself to route a product forward or backward after the weight decision. The MQ-CW3523T1 covers 1-1,000 g at ±0.02-0.1 g and up to 35 packs/min; the MQ-CW3016F05 covers 1-500 g at ±0.06-1 g and up to 70 packs/min. They suit small parts, traditional Chinese medicine pouches and packaged goods where a compact accept/reject or under/target/over workflow is needed without a pneumatic pusher. For fish, poultry, seafood and other true multi-grade applications, use the separate multi-outlet weight sorter range.

A forward-reverse sorting scale is a dynamic checkweighing system whose conveyor changes direction after weighing. Based on the active recipe and weight limits, the belt sends a product to the designated discharge path. It is a compact alternative to a pusher or air-blast rejector for suitable products and speeds. It is not the same as a multi-grade weight sorter, which sends every item to one of several weight-class outlets.

Forward-Reverse Sorting Scales: Working Principle

Forward reverse sorting scale working principle for accept, underweight and overweight decisions

Sorting Scale Price Factors

Forward-reverse sorting scale price depends on weighing range, accuracy target, pack dimensions, required line speed, number of discharge paths and optional data, printing or code-reading functions. Because belt reversal changes the motion cycle, the correct specification must be verified with the real product and spacing. MIQI provides a configuration quote after sample and throughput review rather than using an unsupported universal price.

Forward-Reverse Sorting Applications

Small hardware and kit verification

The system uses total weight to separate complete sets from packs with missing or extra small components.

Herbal and medicine pouches

MQ-CW3016F05 is documented for traditional Chinese medicine decoction-piece packs requiring rapid weight screening.

Light packaged goods

Underweight, target and overweight decisions can be routed through a compact conveyor arrangement.

Lines without compressed air

The weighing belt provides the diverting movement, avoiding a pneumatic pusher at the sorting point.

Delicate or unstable packs

A product trial determines whether controlled belt direction is gentler and more reliable than a side-impact rejector.

Frequently Asked Questions

How does a forward-reverse sorting scale work?+

The product is weighed dynamically, the controller compares the result with the selected recipe limits, and the weighing conveyor then runs in the programmed direction to discharge the product. The exact outlet arrangement is designed around the line layout and product flow.

Is a forward-reverse sorter a food grading machine?+

It can separate a limited number of weight decisions, but it is not the correct owner for fish, poultry or seafood multi-grade searches. Those applications need the multi-outlet weight sorter range, which distributes products to several weight classes.

Why use belt reversal instead of a pusher?+

Belt reversal can remove the need for compressed air and a side-impact mechanism. It may suit compact layouts or products that should not be struck by a pusher. Speed, product stability and discharge clearance must be confirmed with samples.

Which model is more suitable for very small packs?+

MQ-CW3016F05 covers 1-500 g at up to 70 packs/min, while MQ-CW3523T1 covers 1-1,000 g at up to 35 packs/min with a finer stated accuracy range. The right choice depends on pack footprint, target tolerance and real line conditions.
