transporting waiting.

Hi All,

I'm doing a model and I just need to program 1 thing to have it.

In the attach model the process is right until second 4900. Please run the model until this second.

Here you can see that muy transporter1 is getting two items from the processor and going to the queue4, then this both items goes automatically to the separator where they will be unload and separeted ( boxes by the crane 2 to the queue5 and pallets automatically to the queue6). This process is all correct.

But what is wrong is that, as you can see on the 4952 second, the transporter1 is going again to the queue 3 to carry two items placed there. What I need to do is that this transporter1 wait until the crane2 unload all the boxes (8 items ( four for each pallet) in the queue 5) to start this movement.

I attach here the model, some resources are not turned... but I think it's enough to understand what I want to do.

Someone can help me?

Hello @Eric C2,

I used On Process Finish triggers on Processor 4 to close the output of Queue 3 and then I created a process flow that counts the boxes unloaded into Queue5 to then decide when to open the output for Queue 3. The model runs continuously now.

Hi Jeanette,

Thank you for your answer but the solution is not good, as you can see in the image I attach, the transporter1 is moving before the crane unload the 8 items to the queue. This is not right, I need that the transporter1 wait until the crane finishes its unload.

Hello @Eric C2,

That is because the Transporter is going to Queue 6 to unload. The triggers and process flow can also close and open that Queue's output port if you would like it to.

Yes, the tranporter is going to Queue6 and I don' t want that. I want to wait and then goes to the queue 3.

Thank you.

Hi Eric,

is not completely clear to me in which conditions you don't want the transporter to do the transport task from queue3 to processor4. In the attached model, I am checking exactly what you said, after unloading, the transport will stop until queue5 has 8 items and then resume. My guess is that you need a more generic logic, but this can probably give you a trail to follow.

Hi Marcello,

Thank you for your answer.

Your model do what I want, but if you keep going the model at second 9000 it finishes, I want to keep it working.

On this second the token of the process flow stay in the wait for event you have created and don't keep going, so the model finishes working.

The transporter should wait again until the crane unload the 8 items and start again its movements and so on.

Do you know how to do it?

Thank you.
