Hello, I have been trying to get a part of my program to function the way I need it to for 2 1/2 weeks with no success. I know it is something simple that I am not seeing. What I am trying to do is divert 1 part to one machine for every 2 parts that go past the diverter to another machine. The parts travel along a conveyor system. The problem that I am having is when I am diverting the 1 part the next part of the program that lets 2 parts go is starting. I think the problem is in my section that releases one part. WHat I think is happening is it is not getting the done signal fast enough and is repeating it self. I will attach the program in a zip file format. I have been using micro win for programming it. I am sure there will be questions. The section that you need to look at is "L10 L5 Distribution" as well as "Program Block"Attachment1020 23 conveyance rev.4.3.zip (438 Downloads) |

Thank you for taking the time to look at my program. I am pretty new when it comes to creating programs. I did not know about the SM bits so thats why I did not use them. The C6 counter is another good point. I don't even use it in the program so I will just take it out of that rung. I have changed the logic so much over the last week trying to debugg it!! I did however in the meantime get my main issue of 2 parts going to early. It was in the divertion to L10 which should only receive 1 part. Because of the travel of the part the logic was becoming true again for that rung and re staging the part. I am attaching the revised program so you can see how I got around that issue. As well I am doing a 1:1 ratio because the L10 machine was always waiting for parts. The only issue I have left is when the L5 magazine is full but the L10 infeed conveyor is not, my parts are not released from the stager to go into the L10. The only thing that happens is my gate extends.(which is one of the things I need to happen. I do not have any issues when the L10 infeed conveyor is full.The main stager will release parts the L5 magazine as needed untill full or untill the L10 needs parts again. Again, probably a simple fix that I am not seeing. Attachment1020 23 conveyance rev.4.4.zip (435 Downloads) |

Q0.5 is for the gate that extends so the part that goes to L10 can be stoped infront of the kicker. Q0.1 is the main stager that releases parts onto the conveyor. I am attaching the version that seems to be working. Thanks for your help Rosa. Attachment1020 23 conveyance rev.4.8.zip (428 Downloads) |
