Release item in conveyor

During the simulation, the souce goes on inserting new items in the conveyor. Noting that the queue which the items are being placed has a maximum capacity of 1, how can I release the box that is still waiting on the conveyor so the proccess can continue normally?

The DP's current trigger:

There are two options:

If the objective is to release the queue where items are being placed, it is necessary to add a connection after the queue. The queue has the property of holding the item, and if there is no connection after it, the item cannot exit, and the items will not allow for flow.

The second option is, in the "Send Item" trigger, to check whether the queue is empty or not. If it is empty, the robot can move the item. In case it is occupied (occupation = 1), the item must recirculate.

For this purpose, in the DP condition, it is necessary to check the occupation with the following code:

Attached is an example.

Thanks Gustavo! The idea is to recirculate in case of the Queue is full (maximum capacity of 1). Just one more thing, would be possible for you to upload your model on FlexSim 22.0.16 Version? I wasn't able to take a look on it due to it's version.

Thanks again!

Thanks again!

Testing some other methods of items arrival, noticed that depending on the arrival method or queue's maximum capacity, the trigger may fail and add more than one item on the queue. Do you have any idea on what's the problem? Or I'm actually doing something wrong?

Have a great day
