Why does conveyor build queue before robot will unload?

source-sink-3D (1).fsm

Hello,

I thought I posted this earlier but it doesn't appear I was successful.

I'm trying to build a simulation, showing a small segment of material flow. Pieces are created, batched into groups of 4 for combination into 1 unit, loaded onto a conveyor via robot, unloaded via robot to a separator, then separated and released individually. I did this in 3d model.

The unloading robot waits until a group of 4 units (not pieces) arrives before unloading; it needs to unload as they are presented. It's only an issue at the beginning of the model, and/or when the speed of material flow always has items waiting for it. Is this a parameter that I overlooked?

Is it advisable to do this in process flow? I began to build a second model side by side with process flow, but thought I should reach out.

Thanks for any help.

Stephen

Thank you for letting me know, @Jörg Vogel. Should work now.

Hi Stephen,

You have configured the conveyor as a slug builder with a slug size of 4 items, so it's waiting until it has a slug of 4 items before releasing them all at once.

If you uncheck Slug Builder in the properties of ConveyorType1 it will return to its default behaviour of releasing items as they arrive.

Thanks @Allister Wilson, that did the trick. Once I saw that, I remembered configuring it initially as one of my attempts to get it to work how I wanted. I (clearly) didn't go back through and uncheck it as I was making other modifications. Thank you!
