Elscint recently supplied a vibratory bowl feeder for feeding of ceramic barrels used in manufacturing fuses. There was a variety of barrels which were to be fed in the same bowl feeder. The sizes ranged from dia 20 mm to dia 40 mm while the length was same i.e. 40 mm. Most of the barrels had the diameter less than the length, however, in one case, i.e. the largest one, the diameter was same as the length. Wherever the diameter is equal to the length, there are complications in feeding of the same. The orientation required was “rolling” and speed or feed rate required was 30 parts per minute. Elscint designed a unique concept wherein the barrels were fed axially and then rolled out centrally. The advantage of this as against that of twisting each barrel to feed the same was that the changeover required was less as the length of all the barrels was the same. A small lengthwise chute was supplied along with the bowl feeder which was adjustable for the diameter of the barrel. A speed of more than 50 parts per minute was easily achieved for all the sizes of barrels. A cast aluminium bowl was used for this application duly coated with Elscinthane PU coating. You can watch the video of the bowl feeder.
