Roller-cam scissor lift

is based on two or more parallel belts with cylindrical rollers installed between them. In the initial state, the rollers are below the conveying level of the belts so that the goods are conveyed over them. For discharge, the rollers are lifted above the belt level and driven so that any goods on them are discharged from the conveyor at an angle of 90 degrees, depending on the direction of roller rotation.
