High-Speed Roller Conveyor
Robust & User-Friendly
Energy Efficient & Sustainable
A 40 kg range with a 1 g minimum scale, on a 900 × 500 mm belt that hands the pack to a roller takeaway. The pack arrives from the sealer, crosses the weighing section at 10 to 30 m/min and leaves on rollers, so this frame is the weighing station of a line rather than a stand-alone machine. Weigh each pack against the target held for it, and push the short ones off.
A failed pack is pushed off the rollers rather than carried past. The pusher sits across the roller takeaway on twin guide rods, driven by a cylinder behind the frame: on NG the plate travels across the belt width and takes the pack off sideways, so nothing is caught by hand and the run keeps moving.
The same frame can be built with a flap, an air blow or a swing arm instead. All four are pneumatic, so the line needs 0.6 to 1 MPa of external air.

The band depends on the pack, not only on the load cell. A carton that arrives square and crosses the weighing section at a steady speed reads as below; a sack that drops on or comes in at an angle wants a slower belt. The 1 g scale is there so a missing screw shows up long before the total drifts out of tolerance.
Zero tracking runs continuously, with manual or automatic zero clearing following the drift as the belt turns. Up to 100 stored programmes keep the settings for each pack, recalled from the 10-inch colour touch screen, and the learning function stores a target from a run of good packs.
The weighing belt is 900 mm long and 500 mm wide in food grade PVC, so a pack up to 650 × 490 mm sits wholly on it with room to settle. Speed is adjustable from 10 to 30 m/min, which lets you trade throughput against the settling time a heavier pack needs.
Behind the belt it is a roller run, built as its own frame on its own legs — which is what lets a pack be pushed off sideways without disturbing the weighing section. A geared motor bolted to the frame drives the belt from one end.
A sensor sees the pack arrive, the weighing section is where the cell reads it, and the verdict is carried out at the end of the roller run. The cell samples continuously, so the controller holds a curve across the whole pass rather than one snapshot: the software takes the stable part of it, compares it with the target and tolerance stored for that pack, and decides good or NG. On NG the lamp reports and the pusher fires.
Weight records come out through USB, RS232 or RS485, so the data can go to a printer, a PLC or a line system.
The 40 kg range with the 900 × 500 mm belt is for cartons, sacks, drums and boxed goods up to 650 × 490 mm and 40 kg a piece, at up to about 30 packs a minute — packing halls where the check is the last guard before the pallet.
It is not the frame for sachets, small pharmaceutical packs or anything weighed in fractions of a gram; those want a narrower belt and a finer scale. Nor is it intended for pallet loads. Send the pack size and the weight per piece and we will say which frame the job belongs on.
Every unit is assembled and run on our own floor before it is packed.
Cartons, sacks, drums and boxed goods up to 650 mm long, 490 mm wide and 40 kg each.
± 5 g to ± 10 g on a pack crossing at a steady speed, with a 1 g minimum scale. Tell us what you are weighing and we will say what this frame can hold.
The lamp reports and the pusher takes it off the rollers sideways. A flap, an air blow or a swing arm can be fitted instead.
Yes. The pack is fed by conveyor and weighed in motion, so it is an auto check weigher, not a bench scale.
This frame is a checkweigher only. If you also need contamination screening, a checkweigher metal detector combination is a different build.
Belt length and width, the rejection device, the accuracy and the finish. Send the pack and the line speed and we will quote the checkweigher conveyor price against that build.
Whole machine one year, with parts replaced free inside it. It ships by sea, air or international express, and payment can go through Alibaba Trade Assurance.
Send the pack size, the weight per piece and your belt speed. We will come back on fit, on the accuracy you can hold and on how a failed pack should leave your line.
