Tracking boxes (shift register)

Hey guys, I have to work on a project using AB plc. I have 12 indeed conveyors from which boxes are enter into the main conveyor. The main conveyor drives the boxes through a certain distance, then I have 7 out feed conveyors where the boxes are discharged.
I don't know how to go about this. I really would appreciate any info u share on this.

What you have posted is similar to asking the question, "How does an airplane fly"? and answering with "It goes up."

How is the release of the boxes controlled? How far away are the diverts? What kind of diverts do you have? Is there an encoder involved? Do the boxes have unique identifiers? What type of conveyor is used? Does the PLC have other jobs besides running this conveyor?

Think about your process and then coherently transfer the answers to a post because, if anyone else replies these questions, and more, will surely arise.

The title of the thread "Tracking boxes (shift register)"

How many different kinds of boxes are you dealing with? Does it matter what outfeed lane a certain box ends up in? Is there only one kind of box, but you want them distributed evenly to all 7 outfeed lanes. A few more details would be very helpful.

The basic idea of a bit shift is explained in this video:

Will.

for every place of the main conveyer use a byte in an array.
infeed: if inf[1] not empty AND conv [pos+1] is empty shove the box on to conveyer.
conv[pos+1] = inf[1] holdng the destination
outfeed if outf[3]= conv[pos + 103] then push off.
