How can I limit the unload slots on a basicTE

Stefan13 — Thu, 29 Aug 2024 06:32:24 GMT

[ FlexSim 24.2.0 ]

I have that turntable and I want slots 1 and 2 each to be able to unload only where they are allowed i.e. slot 1 only on 1 or 2 columns and slot 2 only on 1 or 2 columns

I want it to have the constraint exactly as in the picture above, to be able to go on the columns where arrows are indicated and that's it. I tried to create a list with the slots where to put the corresponding transfer points but it didn't work, because I still want to put round robbin Varianta_Functionala.fsm

Could this be solved by having the left/single bank only pull if the item will be loaded on the first position (which you can track using the output stats)?

I can't move the bang left or right at unload because it goes out of the maximum working stroke and I would like to avoid this by unloading in certain positions or always unloading the first box and then the second one to slide on the turntable

To me it looks like the centre set of entry transfers can receive any box, while the outside sets can only receive odd or even 'numbered' items depending on which side it is.

Yes, that's exactly right, but I don't know exactly how to do that.

Depends how exactly you want to go about it. If you leave the decision about where the items go random, then you require logic that checks if an item is forced to use one of the two slots. If a second item would need the same slot, it can't be loaded and only one item is moved that time.

Something like this:

varianta-functionala_1.fsm

You can of course also always load two items and only then where to unload them to. Possibly by having a list of entry transfers, each marked whether they can only receive items from certain slots. Then you pull one transfer for each item and unload to them. For each transfer you could have a photo eye or decision point on the conveyor that pushes the transfer back to the list once the item has passed.
