Basically what we want to do is have a big roll of pipe on one end, sew some fabric around it and roll it up on the other end in various lengths and widths. Perhaps the CJ1W-MCH71 might be easier as it has an actual traverse function? Initally there will be about 4 or 5 different products we make, but this could increase to about 8, and we do the the occasional custom order so it would be nice if adding new traverse settings was easy.

Some motor control units I have used before have an electronic brake and a ramp up/down function which will accellerate the motor at a set speed, rather than just apply power. Perhaps yours has this function?

Hi all, I'm still a newbie at motion control so I'd appreciate knowing if I'm heading in the right direction here! I'm currently building a traverse winding machine for plastic irrigation pipe (15mm). We need about 4 or 5 traverse patterns, selectable at startup. It seems to me that I need a CJ1M-CPU2x (encoder input and output to sewing machine motor) and a CJ1W-NC2xx (winding and traverse axis). Is this right or is there a better way?

Hi everyone, Well, I hope I'm not in over my head here, but for my first PLC project I'm building a pipe rollup machine. It's basically just a duplicate of what we already have, except the other machine I built with an embedded microprocessor based controller. Since it has customised electronics I thought I would go with a PLC system this time so I'm not the only one who can fix it when it breaks! What this machine does: On one end we have a 400m spool of 13mm polly pipe (garden irrigation stuff). This then goes past a hotmelt glue gun where a bead of glue is applied every 50cm. 80mm wide fabric is then wrapped around the pipe. This is fed past a sewing machine where the edges of the fabric are joined, and finally it is rolled up onto a spool (200m and 50m for now). Line speed past the sewing machine must remain constant, and be variable from 0 - 33m/min. In the other machine we have two SEW eurodrive units linked, but I don't like them and want to find better units. Now for the fun part: The final spool must move back and fowards so that the rolls are even and neatly rolled. In the other machine I did this by varing the speed of the motor that moved the spool, making it proportional to the product type, length and line speed. This works ok, but would be much better if I could just send a position signal rather than a speed signal. I'm looking at Omron gear at the moment, it seems the easiest to get in Australia, but other sugestions are ok. Budget is $0 or as close to it as possible! Things are very tight at the moment.
