first of all: sorry for the late reply 
(I was pretty busy the last couple of days) 
and thanks a lot for the extensive replies!

If I understand correctly, James Howison's proposed solution entails 
that I would have to bind the restriction to the property. 
Since there are many
different specializations of machines which can handle very 
different kinds of objects, I'd have to introduce one property for every
machine/object combination.

I have to admit, I have no idea how to implement such statement in protege. 
But even if, wouldn't I still have to assert canisters to the
property manually?

I made a screenshot of my "problem". This is the function I am looking for, but
kind of synchronized. (It's partially in german, I hope it is understandable
though ;) )
