Transport pallets from multiple floor storages to queues

Hi all!

I'm a new Flexsim user and I've been dealing with building a model.

I have several questions regarding the transportation of pallets (with boxes) to a system of conveyors.

My case is the following: I have a group of floor storages that have pallets with boxes. These floor storages are constantly filled. A group of 4 forklifts must be in charge of collecting the pallets with boxes (it can collect 1 pallet with boxes per trip) and taking them to a group of queues that are connected with conveyor belts that make them go through a process.

And the conveyors system looks like this:

Additionally, after the forklift leaves a pallet in one of these queues connected to conveyors, it must remove them from an exit queue (it can pick up only 1 pallet too) and leave them on racks. And repeat the process again.

I already have the part set up where the floor storages are filled with pallets, but what I can't get is for the forklift group to remove these pallets with boxes from the floorstorages to the queues that are connected with the conveyor belts.

I have made multiple attempts in process flow that include using lists and find item but they didn't work well. I think I must use them but I got stuck and I couldn't do it.

These are some of my attempts:

In this one I wanted to create something similar to a sub flow, but I didn't do it right. And I think my decide didn't work very well too. Find item helped me to find the pallets, but I didn't know how to specify the floorstorages instead of the racks.

Here I tried with an event trigered source. I think this process is better, but the problem was that the tokens never went to aquire transporter. Probably there was a problem with the source or the list?

If someone can possibly provide me with a brief demo in a simplified approach of this process, I would really appreciate it! If not, any tips or advice that can assist me with my situation will also do!

Hi Felipe,

Could you attach your model to review it? This way it is easier to see why your logic is not working.

Hi @Diego Avila, thanks for offering your help, and sorry for not having answered you before, I had problems making a simpler version of the file I wanted to share, but I decided to ask a more specific question in the next post regarding transporting pallets from a queue to racks with different dimensions:
