The operator moves a batch of items

Hello,

In my model, an operator needs to transport a batch of items to a rack and unload them one by one. Currently, I am facing an issue where the operator does not return to the original location to continue loading after unloading an item. I am unsure how to initiate a new transport cycle.

Additionally, I would like the items to remain on the rack for 100 seconds before being moved away in groups of five by the same operator.

Thank you very much!

You need to release the operator again, so another token can acquire it.

Currently each item that enters Queue3 triggers the creation of a token. This token then moves 5 items. So 5 items are moved per item in Queue3 which won't hold up for long.

You can simplify your Process Flow a lot by first batching the tokens and making an array label that contains all five items while doing so.

The rest is then just running load and unload subflows for each of the items.
