Before I get to answering your question, I would like to point something out to you that will be helpful as you continue to build models. When it comes to process flow, if you are copying and repeating a section of activities then you should rethink your process flow. In other words, if you are copying and repeating try to eliminate or reduce the repetition or copying. Often, a solution to repetition in the process flow is to take advantage of labels.
I condensed your process flow that you had. The main differnece are I used the aquire resource activity to assign an operator to pick up the item. Please take note the Travel task to the verticle conveyor has some custom code. Beyond that it's basically the same process flow you had before.
