Controlling conveyor content

I have a model where different items type a send to different belts for packing. How do I control the max content of the lane conveyor belt to be at 8 units? (if lane conveyor belt have 8 units on it, the package will carry on the main conveyor belt and make a loop until space is open up.

I tried using photo eye, but it is not very accurate because if I set the clear time too long, it will skip alot of packages, if i set it too short, it cannot control the content at 8 packages

@Roger W

You need to check the current content of the conveyor. I have attached your model with some changes.

In the attached model, In DP2>>On Arrival trigger, I wrote the below code in order to send the items to lane conveyor based on item type as well as lane conveyor current content. if the condition is not met items remains in the main conveyor. 

int laneconvcontent = content(node("Conveyor16", model()));
if (getitemtype(item) == 2  && laneconvcontent < 8) 
{
	treenode newDest = outobject(current, 1);
	conveyorsenditem(item, newDest);
}

I hope this will help you.
