This continuously driven modular belt-type edge positioning conveyor is used to transport items. It only needs a 2.2Kw drive motor to transport a distance of 5m. On a straight conveyor line, the conveying speed of a unit load of 80 kg/m in conveying mode can reach 2 m/s. The conveyor can be fully or partially operated as a zero pressure accumulation conveyor. Convert the flow of parcels into a parcel flow with left and right edge spacing, prepare for subsequent DWS and sorting and supply processing steps, and ensure that parcels will not overlap or be side by side during the single-piece separation process. More importantly, these functions do not require any control system.
