Hello
Just wanted some opinions (good or bad) on the following ladder.
http://www.angelfire.com/in4/bobbyallen/ladder.html
About the process, We run cast aluminum oil pans for Honda and this particular line runs 4 models. The last process installs 2 dowel pins into the pan for alignment with the engine block, then the pan is put onto a compound jig that checks all the holes for proper location. This process is all mechanical with stationary and push pins checking the holes. They first decided to add dowel pins sensors then a week later wanted sensors to check for warpage of the pan. We use 2 seperate compound jigs, each check two different pan models. The PLC in the pin press machine was full so we installed a small plc and use output O:0/1 to feed X27 on old plc. X27 is always on unless alarm condition.
If the operator pushes a pan onto the jig and all the sensors dont come on they get a RED light. Im also checking for stuck/broke sensors. This is a small program and not much of a problem, just wanted to get ideas on other ways? Maybe bit comparisions? I know you can ask 10 people to do this and get 10 different ladders.
thanks for any pointers.
Bob
you all have a safe and happy 4th.
