Attached is a VersaPro version 2.02 program in a zip file.
I have redone 2 machines and the 2nd machine, along with the tech/operator, offered some different insights to the machine. I have made many modifications to my original program. I have also made many efforts to organize/sequence the data to follow the machine operation. There are some minor electromechanical differences between the machines that I am working to eliminate. The program even with the differences is the same for the 2 machines I have done. I have more features to incorporate that are now self sufficient but since a plc is there it would eliminate the need for a high cost photoeye/timer (MKE-90). That part I will get to later.
What I hope is that some of you can look at the VersaPro file, I would make it a pic but havent determined how, and offer suggestions to clean it up. If needed I will offer my feeble attempt at a DWG drawing to show the system. My feeble attempt to me is a 1000% better than the way it was originally wired and drawn. I can not go into details of what I have had to do to obtain a working program that can create decent drawings but they are only available on a computer at work and I didnt think to make a copy, I will make one and load it at the first opportunity.
Most of you know that I am not a programmer, more from lack of opportunity than lack of desire, nor am I an engineer but I like the chance to do things in this area.
This program has 25 rungs for an L sealer..ie the product enters at a right angle to the pusher ram which delays (photoeye is a couple of inches before pusher) then pushes the product under a cutter head. The cutter head, as soon as the pusher ram has cleared the head, travels down. When the head is down a limit switch is made that starts the heat/seal/cut time, when this time is done then the head "dwell", time head stays after heat/seal/cut, is started. As soon as the dwell time is done then outfeed conveyor and cooling air (air blowing on seal) is started, these have there own timers to determine length they are on. ALSO in this process, at the beginning, is a pulse sequence (note: these may be name backwards) to allow the heat/cut/seal to maintain a consistent temperature. I have this set to pulse the heat at approximately the time the machine would operate if running at max capacity. The pusle does NOT operate when the head is down and the heat/cut/seal operation is in action.
Thank you for any assistance.
