I have a (potential) customer who has a Bekum H-151 blow molding machine and they would like to update the controls. This machine is about 1988 vintage, and I believe it has been updated once. It now has an Invensys PC running wonderware for an operator interface, a SLC 5/04 plc, Barber Coleman controller of some kind, and a 75HP DC Motor Drive. Oh, and their is Modbus tying some of it together, some (Remote) Flex I/O and its basically a hodge-podge mess. The customer has ZERO documentation on this machine. Apparently they don't know much about their machine, either.
I have no experience with blow molders and would like to learn the basics of how this machine works. Does anyone have and manuals on this, or a similar machine, that I could look at? Bekum wants $350 for a documentation set.
Also, I'd like to learn more about the Parison control. If I'm not mistaken, there are 2, dedicated controllers, for this. What exactly do they do and would it be worth replacing them?
I'm trying to get to the point where I understand the machine enough to put an I/O list together, come up with more readily available components and create a proposal. The lack of information is holding me back.
Thanks.
