I hope anyone can help me out.
I am looking for a pull control/method that allows me to Pull parts in a specific sequence over and over again (loop).
For example: There are 6 machines that produce parts. When finished, the produced part shall be put onto a conveyor belt and transported to the next machine. The sequence should be for example: (M1, M2, M6, M3, M4, M6, M5, M1, M6). The Successor of the machines (conveyor belt or the next machine) shall ask for the parts of these machines. If the part from M1, is not ready, the machine or conveyor belt shall wait for it. When it is delivered, it shall ask (pull) the next part from M2 and so on...
My programming language knowledge is not very good, so I am really looking forward for someone who can help me out. Maybe with an example of the method or the other material- or information flow parts needed.
Thanks in advance
you can see your described case implemented in the attached example. The part here is moved around by utilizing sensors on the line calling predefined methods and exit controls of the machines that are positioned in a row. Would that work for your application? If not could you provide a picture of what kind of layout you had in mind?
So from your model I see that your machines are getting parts from both their sources and also the other machines, is that correct? And the machines are supposed to be aligned relative to only one conveyor belt?
you can use an entrance control in the line to pull a part from a predecessor depend on the list with the order
(I have changed it to stations, it is easier to program)
The first time you need to call the method by the init-method to start waiting for the first part.
