This system receives stacks of totes (eventually nested) and delivers emtied totes at the following system.
Stacks of totes can be loaden onto the conveyor (eventually with the help of a balancer) and the stacks are buffered. The stacks are automatically destacked and transported through a trash removing spiral. The trash which was remaining in the totes is falling out directly into a disposal container. The empty totes are now handed over to the next trajectory.
