How to unload as specific trailer out of several at a specific control point

The 1st simulation file contains the main goal ...

16-12-15autoload-layout-10.fsm

The 2nd simulation file was downloaded to learn and tweak for helping complete agenda ...

agv-tote-trailors-load-boxes.fsm

AGENDA ...studying timing of pallets loaded to a pallatalizer by cycle (color coded) vs. speed compared to dolly train loaded and traveling up to pallatalizer. Once dollies (train) receives pallets at same time onto each dolly (trailer) then dolly train system drives off for delivery. There will be a total of 6-dolly trains attached with 6-dollies (trains) each for total system. I am trying to understand how to keep AGV from receiving a pallet and only the trains. Later I will need to learn how to drop off pallet from one of the specific dollies during delivery route thru manufacturing plant. This project referenced from dock door delivery from Tractor trailers.

Thanks Much for any direction ...:),

I'm still not sure I know exactly what you're asking here, could you please clarify a bit more?

I want to keep 6-dollies I have designed pulled behind Tugger (Toyota 8TB50 standup) (which I have model) ...everything has been saved as 3DS files

Ultimately, I want to use simulation package to determine how much time does it take pallets loaded (by fork truck) at rear of single tier palletizer to tranfer by powered conveyor to 6-dolly dolly location points

The tugger pulling 6-dollies will drive up ...stop along side palletizers at 6-dolly transfer locations points and receive all 6-pallets onto all 6-dollies at same time. Once pallets load to dollies ...tugger pulls away from palletizer to deliver commodities to line side within assembly plant

Once 1-dolly train system of 6-dollies functions correctly, then as many as 16-dolly trains my be included to study timing of pickup and drop off

Once this study is completed, then another study to figure how many and how fast fork trucks needed to supply pallets to palletizer. The palletizer constraint will need to include handling cycle loading (meaning the assembly line needs each dolly train loaded with specific cycle requires from production control ordering & match specific pallet loaded per dolly). Trying to keep simple as building system and add complexity later

Cycles are determined by product currently required at assembly line ...match product requirement (color. material etc ...) needing specific components delivered because no space at line side except what is needed at current timing ...LEAN MANUFACTURING

Any help gratly appreciated ...

Thanks,

Dan

@Jacob Gillespie How can we increase the dolly capacity in this model? I want to load 5 boxes in each dolly at a time.

@Chitra J,

According to the Answers Best Practices, it generally helps your question be seen if you post a new question and reference this one using a link. That way, more people will see your question. This question is very old and not as many users will see it.

For the first part of your question: "how to keep AGV from receiving a pallet and only the trains"

The AGV is the one that receives each pallet, which then moves it to a dolly.

To make it leave the station the AGV has to be full (with one pallet). So just move the pallet to the last dolly immediately after leaving the loading station (use OnAGVStartTravel).

See the attached model: 16-12-15autoload-layout-10-edit.fsm

EDIT:

It looks like you are using Process Flow for only part of the AGV stuff. I suggest you take a look at "AGV Lesson 2 Step-By-Step Model Construction" in the user manual. It tells you how to use AGV Process Flow.

I used the "AGV" Process Flow Task Executer template and then added in the dolly logic you had previously made. I then switched the queues' Use Transport to Use List > Push to Item List (No Task Sequence) using the AGVWork list. Next added a loop of NextLookForWork connections.

It now works with two trains: 16-12-15autoload-layout-10-edit2.fsm

Awsome ...checking it out now

That works perfect ...now I am working on the AGV function to allow the 2nd dolly train to retrieve pallets (currently sets at pick point) ...Thinking I need to somehow make the port not be the restriction. Thinking the Break To may have effect but not sure ...:)

Jacob Gillespie ...thanks again ...I have ready and studied the process flow & AGV functions ..."WOW" these documents and this software is extreme powerful
