How operator can load 2 items at once by label?

[_3gsimulator]

[ FlexSim 21.2.0 ]

In the end of production line, operator must load two items - pad and chassis. I set those items label at the queue "take" but in the process flow i don't know what to put in the LOAD that it takes these items by label.

Do you know how can load 2 items? Shall I use labels, or something else? Before i had only two items so there was "token.item.first" and operators loaded only first item. But I didn't find option like: take first two items.

See attached model where I've altered your Process Flow.

The items in the queue need to be split up and sent a list. This is because there are 3 subitems loaded onto the tray object, and it makes things easier if we can pick and choose what we load.

Then we pull 2 items that have the label take = 1.

The load and unload activities are also done with subflows to handle both items.

Let me know if you have any questions! I noticed there are a few errors that are still showing up, let me know if you can't resolve them and I can take another look at them.

Thank you. Great i can see how to use subflow. Thank you for your help and time. So pushing and pulling from list is the way.

Please, can you help me to solve, how operators can unload those 2 items into the trolley together? That is it in one bay in same position like on the tray object? I tried trigger on the queque (on the elevator) - i can set location, set rotation or visual, but no way to get them together.

Thank you

If you want the items to stay together, you can change the process flow to this:

This will allow you to unload one item on the rack so it is only taking up one slot, then unload the second item onto the first.

@Parker S Thank you

The last thing I am fighting and is connected to all solved is:

The last item ("totek" = 1) when it arrives back to the begging of the line, the operator must load it and unload it into the queque7.

It shows error that the label is missing, but when i stop simulation, it is there.

The queque on the elevator pushes the token into the list "readyforpickup_1".

Can you please help me? Thank you.

@Parker S so I put in decision point option to push it in to the list. But operator on the load takes completely all pallet, not just the small tote with label name "totek"

Can you upload your model again? There seems to be an issue with the file.

Thank you very much!

Please see new model and changes to your process flow. There is no need to push the totes to a list and pull them back, you can just load and unload them directly. I didn't find Queue7, so I created a queue called "UsedTotes" that the operator unloads to.
