Have a project we are looking at that will be as follows.
There will be a roll of fabric that will be fed through a conveyor system that will use a set of Nip rollers to pull the fabric through. The fabric will be pulled from the roll and then a chemical will be sprayed onto the fabric. After the fabric is sprayed the first, or bottom roll of fabric will then have another roll of fabric that will be laminated to it by being pulled through the same set of Nip rollers. The second roll of top layer of the fabric will be driven by some type of motor to ensure that when it is pulled through the nip rollers that it is running the same speed as the bottom roll of fabric. The chemical that is being sprayed will cause a chemical reaction to occur and the two types of fabric will be laminated together.
I am looking at using a Allen bradley Micrologix 1400 drive to send a 4-20 ma speed reference to the Nip rollers that will be scaled to be 0-10 yards per minute.
I have looked at the Yaskawa A1000 drive and looking at possibly using it in closed loop vector control and then use the pulse signal out of that drive controlling the nip rollers to be in the input reference signal input on the second Yaskawa A1000 drive that will be controlling the top roll as they are fed together through the nip rollers.
If anyone has had any experience with this type of application could you possibly share it? I have done feed conveyors with fabric and controlled the speed of it through drying chambers etc. using Yaskawa drives and dancer switches to trim and maintain the desired speed and tension, but have never tried to mate two pieces of fabric feeding off of rolls together.
Does how I am looing at this make sense, or I am way off base.
Thanks
