Segbert’s Pre-Sorter VVS (Booth 3531) consists of two modules, a lift storage and a stacking system. The height of each bundle is measured at the machine entrance. While the bundle continues to move on the conveyor, the control system determines if the bundle needs to be stored, stacked or can go towards the palletizer. The control system uses an algorithm that is optimized to build stacks of a pre-determined height out of the individual stacks that come into the pre-sorter.
The lift storage system consists of several belts and each belt can store one bundle. Knowing the height of the complete bundle to be palletized, the machine calculates which bundles can be stacked together to reach the required height.
The stacking station consists of 2 lateral alignment plates, lateral fingers and stop bars in front to hold the bundle where it will be stacked. The bundle runs in, stops. At the same time the lateral alignment moves towards the bundle to hold and lift it, the lateral fingers move under the bundle to support and the bundle is lifted. As soon as the next bundle runs in, the first is positioned on the next and the procedure repeats until the required bundle height is reached and the complete bundle runs towards the palletizer in a sequence that makes it possible to palletize the highest bundles at the outer sides of the pallet and the smaller bundles in the center.
