bottleline simulation

I am working on the bottleline simulation for loqixpro simulator. I don't know much about bit shift instructions and how you get it to know where each bottle type is. If you have any ideas on how to keep track of the bottle types, and how you can divert each type let me know.

Link below may help you understand the bit shift instruction.

That is some good info. But i am still lost. I still don't know what instruction set i need to use after, the bit shift left instruction to know when to open the diverter gate.
