I need some help - I'm building a machine but I'm not sure of the best way of doing it.
Thanks a million for your help
Just to refresh my point - I've made one or two changes
I have two large wire spools. One 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 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'm looking to put a motor on the small spool and use this to turn the large spool through the pull of the wire
I will be using one small spool at a time along with one large spool at a time
I want the entire system to shut down once the small spool is full or the large spool is almost empty - whichever happens first
The wire in question is a high carbon wire with a very high tensile strength so this should not be a problem for the wire - I am confident hat the wire will be able to handle the pull as long as there is a slow start up and slow down
The large spool has a weight of 1100lbs (500kg), a diameter of 28 inches (70cm) and a depth of 12 inches (30cm) - in the picture attached there are two large spools stacked on top of eachother on one pallet
The small spool has a diameter of 19 inches (48cm) and a depth of 9 inches (24cm)
I want to unwind the entire contents of the large spool onto 5 smaller spools - each smaller spool will be manually lifted off and replaced with an empty spool each time the small spool is full - maximum rotational weight on the take up spool at any one time is 220lbs (100kg)
I would like to start and stop the small spool slowly - ideally a slow start/stop lasting approximately 3 to 4 seconds
I would like to turn the small spool - the one powered by a motor at between 3 to 5 revolutions per second (180 to 300 rev per minuet)
A uniform wrapping speed is not critical - I am conscious that the wrapping speed will change as the diamter of the larger spool decreases and the diameter of the smaller spool will increase. I don't need any footage count - just plain transfer from one spool to another
I do not have any motors at the moment so any suggestions would be greatly appreciated
I have access to 110 Volt, 230 Volt and 3 phase 400 Volt supply
I don't need the motors to run in reverse just in one direction
I'm hoping to get this done for as cheap as possible - at most €1500
Please give me some suggestions on how to start and stop both motors and the best type of motors for the job
Thanks very much for your help
