How do I make items wait on a conveyor until X number are received?

Hello.

I have an example conveyor model for my question. The items are turned at the conveyor's first decision point. Then they enter a restricted area where they stop and delay at the next decision point (circled in red). After the delay, the item is released and exits the area. Then the delay and release repeats for the next item.

What I actually want is for the decision point (circled in red) to wait for all 4 items to arrive, then release them all at once instead of one by one. The only delay time at the decision point should be the time spent waiting for 4 items to accumulate. I also want this done for the next two decision points but if I can see how to do it for the first two, I can replicate it myself.

Robert,

I moved your DP1 to StraightConveyor15 and deleted the OnArrival code, added a sink at the end of the conveyors, deleted the DP at the end of the last conveyor and changed StraightConveyor7 to be a slug conveyor. See information on slug building in the User Manual here. Is this what you were looking to do?

It seems like the Slug Building options on the Conveyor would be the most direct way to solve this. On your conveyor segment where you want to collect 4 things, go to your Conveyor properties and set the Conveyor Type to Custom to activate the Slug Building options:

This is what I was looking to do. Thank you both.
