Hi:

I think, your problem is that the trigger condition of the event trigger source is to use a TransportReference, but when you finish a pallet, the robot needs to get a new pallet, then the item that enters the Queue at this time will not trigger the event trigger source.

Maybe this model meets your requirements, and some r changes have been made to your model.

@wang.w2,

Attached is your model with the changes that I've made. This is the way I would go about what you are trying to do.

To change the number of flowitems per pallet, just change the "QtyPerPallet" label on Combiner1.

Take a look at the model and see if a solution like this would work for your situation. If you have any questions or problems, please let us know.

Thanks.

@wang.w2,

Attached is the model with the additional changes that I've made.

Take a look at the model and see if it is now doing what you are wanting it to do.

I changed a lot of things around so if you have any questions or problems, please let us know. Basically all you need to do to run the model is to make sure that the label "RobotLoads" on Combiner1 is set to the number of Robot loads (you have the Robot set to hold 3 items) you want per pallet. So, as in the attached model, RobotLoads is set to 4. That means that 12 flowitems will end up on each pallet (Robot max times RobotLoads).

Again, if you have any questions or problems, please let us know.

Thanks
