How to sort items in a transporter

Hello community,

we have a problem with a small modell. We can´t find a solution.

Describtion:
The model includes 3 sources, which creates 3 different labels. We need the label to send the Items into the right queue. In the example file (see attachment) we control that with an pull requirement.

Problem:
In the attached file, the transport traveled first to queue 8, then 7 and last to queue 6. How can I sort the label on the transporter, that he will going to queue 6 first.

Our solution:
First, we has tried to sort the label in the queue. We used the trigger "on exit". - problem persists
In the next step, we wanted to sort the label in the trigger "load" into the transporter. - problem persists

Thanks for answers.

Hi Michael,

please have a look into Queue 5. I'm using the flow control and "sent to port" option to control the material flow. I removed the code from the other queues.

I hope this is useful to you.

Hi Michael,

if you still want to change the order of the unloading process I have attached a small model.
The code is written mostly in the Onload-trigger of the transporter.
First the current active tasksequence ist getting a new priority, which is higher than any not started tasksequence.
The following code checks if the current loaded item is the last. It is the last if there isn't any loading capacity left or there isn't any not-started tasksequence in the tasksequencequeue.
Then is a message sent. OnMessage a preempting tasksequence is dispatched. It consists only of a delay task with no delay time. But that is enough to move the currently active tasksequence back in the tasksequencequeue.
Then all tasksequences are in the queue and the QueueStrategy choose the tasksequence of the highest priority to be executed next.

Hello Mr. Seehafer and Mr. Vogel,

many thanks for your replys. We found a solution for our problems with a mix of both example models.

Merry Christmas and a happy New Year.
Kind regards

Hello all together,

fo me it is a very interessting topic because i'm trying to simplify my self created milk run model.

Now I had some time to have a look at and I think there is a much easier solution.

If you have a look at the Unload-Trigger, you can find the option "Unload all items intended for this station". I used this comand in the sample model and removed all sorting and other coding and it worked well.

Is there anything what I have to look for? To be honest: It seems to easy for me
