Stacking system is to stack the cooled sandwich panels automatically with input quantity by operator. It can be manufactured as a vacuum pad type or a mechanical lifter type.
The vacuum pad type stacks the sandwich panels one by one through the vacuum pad equipped stacker. On the other hands, the mechanical lifter type stacks sandwich panel more than one piece through the mechanical lifter at once. After stacking process, a sandwich panel bundle is moved to wrapping process by longitudinal feeding conveyors.
In case of the corrugated roof panels, a turnover device is necessary. Because if we stack the roof panels without it from the second sandwich panel, it will be stacked on the ribs and then, the stackable quantities will decrease and the paint layer can be damaged during transport.
