I need some help - I'm building a machine but I'm not sure of the best way of doing it.
I have three large wire spools. Two empty and one full. The full spool (approx. 500kg) is much larger than the empty spool (100kg when full). I wish to transfer the wire from the large spool to two of the smaller spools. I want to do this regularly so I want to set up a system that will not have to be monitored but can turn itself off when the smaller spool is full and/or the larger spool is almost empty - whichever happens first.
I want to keep this as simple as possible. I currently have two parallel spindles - one for the large spool and one for the smaller spool with a third parallel shaft in between - a self-reversing screw shaft - this will run a guide back and forth in order to evenly place the wire on the smaller spool.
I'm thinking of using two DC motors (I will have to be able to adjust the speed of the motors driving the spool and self-reversing shaft):
the first motor is to turn the smaller spool, this in turn will pull the wire off the larger spool causing it to turn
and
the second motor to turn the self-reversing screw shaft to guide the wire
and
2 limit switches - one on the smaller spool and one on the larger spool.
The idea behind this is that:
when the larger spool is almost empty the limit switch on it sends a signal back to the motors to cut out
and/or
when the smaller spool is full the limit switch on it sends a signal back to the motors to cut out
Can someone please help me.
Are DC motors and limit switches the simplest, best and cheapest way of doing this or is there another way?
If DC motors and limit switches are the best how would I wire it up so that it works like I described above?
Thanks for your help.
