I have an issue where the operator is unloading the machine they will hold onto a single bottle. I know this is because they are prioritizing reloading the machine but it means they are loading one at a time rather than 2 at time due to the space being used up by the processed item. I am otherwise happy with how they are behaving in that they fill them up and then work there way back up the line again unloading and reloading but I would like them to ensure that their hands are empty before they begin to reload. Is there an easy fix for this?
Any help would be appreciated.
