Operator movement with a capacity of 2 from different sources

I will be glad if one can support me to resolve my query. Here I am having a single operator which has to move to combiner from two different sources. In each source the flow transport is connected with this operator. Here I want that operator has to first pick the items from each source, then has to travel to the combiner in a single time and has to place both the item at once to combiner. The one where I had a problem was the operator is picking and placing the item individually for each source.

If you change the capacity of the operator to 2 it should work. capacityoperator.png

If a fixed resource doesn't behave as someone wishes you can always try to place a queue or several queues in front of this fixed resource. You can hide the content or the queue itself to optimize the visual look.

@Jörg Vogel you are right but it can/does create new problem. For instance in this situation the operator would keep walking and you create extra buffer in your system. In that case you have to start opening and closing ports again which doesn't make it easier.

@steven.hamoen

I tried by changing it but it doesn't work. As I have connected the operator to both of the sources and assigned it to their flow transport.

As it gets the trigger to send to port, the operator gets fire and it picks the item from one source and move to its outport. But I don't want to make the operator move to combiner.

Pick item from source1 ----> travel to source 2 ---> pick item from source2 ---> travel to combiner ---> unload/place both the items together to combiner

Ok I think what is wrong. The combiner excepts only 1 product at it's port 1 and until that product has arrived the other ports are not opened. So this means that only the first source creates a tasksequence and the operator has only 1 tasksequence so it can't combine the 2.

If you let a container (like a pallet) enter through port 1 and have both sources connected to port 2 and 3, it will work because it will open all those other ports at the same time. I attached a model. ( and of course if you don't need the pallet make an invisible object that you generate)

Thanks for the generosity. I am unable to open your model as I have a lower version of flexsim. Can you please illustrate through the images.

Thanks again
