Simple Picking Model.fsmHello, I was trying to create a picking mechanism where packages are coming to the conveyor and are be diverted to a queue dependent on the label "type". For some reason the model only seems to be working for one package.

If you want items to exit a conveyor through an exit transfer that is not the last one point on the conveyor you have to send them there using decision points or photo eyes.
Thank you so much for the help!
I had two follow up questions
1.) I wanted to use only one exit transfer instead of using one for each queue, for this I used an expression on the exit transfer but it only send the items dependent on output connect order instead of using the input pull I had specified. Is there another way I can achieve this?
2. In case the operator isn't able to pick the package in the time(package reaches end on exit transfer- I wanted the packages to go into a buffer zone(I've used a queue for it) and the operator can then go and pick the package once its available from the queue and bring it back to the original queue . I used a photo eye, which if covered should send the item to the queue at the end. But for some reason I'm not able to make it work.Picking Model Phase 2.fsmPicking Model Phase 2.fsm
1) The pull strategy of the queues should always be used as long as it is active. If the exit transfer tries to send an item but the queue won't pull it due to the condition the item will simply not be transfered. To only use the pull strategy simply leave the send to port of the exit transfer as "First Available". (The same is true for the queue at the end)
2) I'am not completely certain on how these interact but it could be that sending the item to a different location doesn't actually cause it to "leave" the first exit transfer. The simple solution for this is to uncheck the "Stop at End" option of the exit transfer. Items that are not picked up will continue along the conveyor and exit through the transfer at the end.
