Help with loading a row of boxes from elevator onto a pallet

Hi everyone,

I'm working on a project where I need to model an automatic palletizer in FlexSim. Specifically, I want to simulate an elevator or an ASRS vehicle (I'd like to test both options) that loads an entire row of boxes onto a pallet—not one box at a time, but a full row in one movement.

The issue I'm facing is that when the row is loaded onto the pallet, all the boxes are placed in the same location, rather than being stacked properly. The result is that they overlap instead of forming a correct layer on the pallet.

How it is working:

How should be working:

What would be the correct way to configure the loading so that the boxes are placed as a row (or later stacked in layers) on the pallet?

Any suggestions or example models would be greatly appreciated!

You are not stacking the boxes on the pallet but other pallets (with the boxes on them). The stacking logic thus uses the height of those pallets for the placement.

You can use the "Pallet Stacking" stacking method (set in the FlowItemBin) so that the pallets are automatically resized to include the boxes within their bounding volume. For that to work the plane must have an actual height (something like 1mm) and the Shape Factors all need to be set to 1.

You could then also hide these 'layers' by deactivating the "Show 3D Object" option.
