Fiberglass motor startup delay versus resin gun startup delay

    On our paint robots we have a chopper that cuts fiberglass, and a gun that sprays resin. Our chopper is not located next to the resin gun but has to travel through a pipe to intersect with the resin. Our chopper is having trouble ramping and keeping pace with the resin gun. As the chopper turns off, there is still some rotation that causes fiberglass excess to come out. With the gun turning on, it does not ramp fast enough to keep up with the resin.


    What can we do to anticipate the travel delay between the resin and the chopper? Since they are in different locations and there is travel for the glass to mix with the resin.


    We have looked at equipment characteristics for the trigger delay, and found that does not work.

    Why doesn't using Triggers work? That's purely on the robot side, so "equipment characteristics" should be irrelevant.


    It does sound as if you would need separate control signals to the chopper and the resin gun, however. Possibly that might require some re-wiring.


    Determining the timing of the Triggers would be up to you, though. And if the time delays between the two different units are not consistent, then this is not a program that can be solved programmatically.
