Problems with exit transfers

Good morning,
The operators are supposed to take the boxes and place them in their corresponding pallet, but sometimes they take one that does not correspond to them and I don´t understand why.
There are superimposed exitransfers on each side of the belt where the operators are.

In the image, you can see that in the combiner 4, where only can be boxes of type 4, there is a box type 2.

Hi @Cetim C,

I made some modifications to your model that should accomplish your desired behavior. Instead of having multiple exit transfers, I changed it to have just one exit transfer and added some logic on the "Send to Port" field to send the item to the correct port. I also added some logic on the "Use Transport" field to have it dispatch the task to the correct operator.

I also modified the logic on the Decision Point and added a couple Decision Points to aid in the Send Item logic on the first DP.

I also noticed a similar problem was happening with the robot arm in addition to the operators, so I reduced the number of exit transfers to one and changed the logic on that exit transfer to send items to the correct port and use the robot arm as the transport.

I hope this helps! Let us know if you have further questions!

Hi @Cetim C,

After playing with your original model for a bit, I realized that if you adjust the positions/lengths of your original exit transfers, you can get your original model to work properly! I've attached that version of your model here:

6destination (1)-rc.fsm

I think I would still recommend my earlier solution since it seems that the exit transfers can be a bit finicky at times, but it's good to know that this other way works as well.

I hope this helps! All the best!
