How to make the queue conditionally release the pallets

Hi,

I am working on the model where I want the queue to only release the items onto the conveyor when the first processor on the conveyor system is free for processing.

I tried to make use of the photo eye but it only stops the item from entering the particular area but doesnt stop the Queue from releasing the pallet.

Please can you help me out by letting me know how can I achieve it?

You can achieve this by using an "On Entry" trigger on Station 1 that is linked to the queue you want to close the output on. When the item enters Station 1, it will close the output of the queue and prevent the AGV from taking another item to the conveyor.

The "On Process Finish" trigger then opens up the queue's output so that items can flow again.

Unfortunately, this won't stop the queue from releasing items while there are items on the conveyor. Only while the item is in the processor will it close the output.

You could implement a "Zone" and photo eyes in Process Flow if you wanted to control a bigger area. Hopefully this at least gives you an idea. I've attached your updated model below.
