What is the fate of an accepted paper in Springer conference but not being presented?
The comments above are the answers you want. I am just reiterating them here because I think the question deserves an answer. If they accepted your paper, it means the conference organizers think it's interesting. You should mention to them your inability to attend, and if you can't for any reason publish it elsewhere, you could ask them if they are willing to review your contribution and publish it. 
Conference organizers often serve as editors of the conference proceedings, so it's entirely up to them to publish it anyway, or not. And they typically do not have any special incentive to go one way or another, so do try!
