I have a processor that uses two types of rolls with different lengths. One roll is consumed by the machine faster than the other one because it is shorter. I built a process flow that makes the operator refill the machine with a new roll each time it has been consumed all up. However, when the operator refills the machine, he changes the two rolls, that means, he changes also the roll that hasn´t finished itself yet. So, what I need to know is how do I make the operator refill only the roll that has finished itself up. I have attached the model.
Pd: I would also want that when the operator changes the roll, the machine stops for a certain amount of time. I was thinking about including a delay, however, I´m not sure where to put it.
Thanks in advance.
