I had exactly the same problem when i was learning and found two things that helps to sort it out. The first was to always starting by having my elbow in the right place before i started to draw the bow (while it was still down) I found the easiest way to do this was to have my arm bent slightly before i raised the bow. It was then just a matter of raising the bow without rotating the elbow out of position. you must remember to check it as you draw the string back. The second method was to move to a more open stance as this moved the arm back out of the way of the string. This vastly reduced the number of times i whacked my arm.
