Model a transfer shuttle with space for 2 boxes

Please help with an idea.

I have 3 conveyors witch are bringing parcels near the shuttle.

I need to make a smooth transition between the conveyors and the shuttle and for the shuttle to load 2 parcels (if there are 2 on the conveyor - if not it should load just 1 parcel and deliver to the 4th conveyor).

Can you please advise ?

Thank you so much.

Hi @Marian Cretu,

I'm not sure what exactly you mean by "smooth transition", but I've updated your model to include logic that handles the loading and unloading of up to two parcels. This is all done using Process Flow and it's not perfect logic, but it should get you started for what you need.

The first photo eye on each conveyor pushes the object to a list, making it available for pickup. The second photo eye triggers the Process Flow activities to pull from the item list then load and unload the items. In the Pull from List activity, I put 2 as the Request Number and 1 as the Require Number, meaning that the activity will pull 2 items if they are available, but only require 1 to function.

Let me know if you have any other questions how it has been set up.
