How to walk the pallets when I have places empty places?

When I do not have a pallet in places enclosed in red, I need them to be covered before product reaches them.

Hi, I come from This Post.

I still not quite understand about what you want.

The pallet will stop 3 times in the conveyor, and the robots or operator will place the different number of box to the pallet each time.

Is that correct?

Maybe with this explain you can understand me better.

I want pallets in this three decision position 3(1), 1(2), 59(3).

The processor have different time of process.

If the robots or operator unload the product in pallet, it advance and the decision point request an empty pallet in the conveyor.

Conditions

1. First all decision points request a pallet.

2. The pallet in decision point 1(2) advance if robot41 unload product and if the pallet in decision point 59 (3) don’t have product wait for unload product from robot1.

3. If first the robot1 unload product in the decision point 59(3), the pallet in decision point 1(2) is released for let it pass pallet from decision point 59(3) and travel for the conveyor. Then the decision points request empty pallets.

4. If decision point 3(1) don’t have pallet, it request an empty pallet. The pallets from decision point 1(2) and 59(3) can travel to decision point 3(1).

It's a little hard to understand exactly what you want by the small amount of details that you have given. But if I understand correctly, all you want is a pallet to be at the processing location when there is a flowitem to be put on the pallet. I hope that is correct.

Attached is your model with the modifications that I have made. I deleted one of your DPs and added another DP at the very beginning of the conveyor. This is the DP (DPMain) that decides what processing location to send the pallet to.

I changed a lot of the code in the other DPs. I think I put comments in where I made changes so I'm hoping that you can follow what I have done. If not, please let me know. I also changed code in the OnMessage trigger of Processor1. I think that just about does it. Take a look at the model and see if it is doing what you are needing it to do and let me know if changes are needed.

Here is the model:
