ST_AS stacking unit

Cartons from the production line are taken from the feed belt of the stratifier.
At the end of the feed belt a pusher, working orthogonally to the direction of arrival of the cartons, moves a few at a time on a descender. As soon as the cases are received, the descender lowers to create space for a new floor. These operations are repeated until the set number of layers is created.
When the stacking operation is finished, another pusher moves the created stacks onto the stack conveyor belt, while more cases are coming in to be layered.
The pile conveyor belt provides for them to be taken out of the stratifier for later packaging
