How to send empty pallet to another destination than non-empty pallet?

In my model I have pallets with boxes. After orderpicking there are two options:

Pallet still contains boxes: send pallet with boxes to rack
Pallet is empty: send pallet to empty pallet storage

How can I achieve this in a 3D model?

Refer to the attachment for a simplified version of my model.

There is another condition necessary to send items to another added output port

if (getvarnum(current,"unpack")) {  if (item.rank == 1){ // add block > curled bracket
    if (!item.subnodes.length) // empty pallet        
        return 3; // 3rd output port    
    return containerport;    
    } // close block > curled bracket  
    else   
     return contentport;} 
else
   return 0;

@Jörg Vogel Thanks a lot! For my own learning: where did you add this additional code in the model? I would like to use it in my actual model.

@Jörg Vogel

In my model I want to transport both empty and non-empty pallets on the same conveyor. Empty pallets are routed to a queue at some point. I updated my model to clarify this point a little better.

Is this possible with the solution you provided? Or do I need to add a label to empty pallets for routing on the conveyor? If yes, how can this be done?
