Four outlet Vibratory Bowl Feeder for very small Springs exported to Canada
Elscint recently manufactured a vibratory bowl feeder for feeding of springs in four outlets. The diameter of the spring was just 2.3 mm and the length was 9 mm. The wire diameter being just 0.8 mm, these springs had a tendency of getting entangled between themselves. However, Elscint designed the bowl in such a way that the entangled springs fell back into the bowl and got disentangled while falling down. Only single disentangled springs came out of the bowl. Additionally, four tubular gravity feeder chutes were provided so that four separate outlets could be provided. At the end of the outlets, a pneumatic singulator was provided to singulate one spring from each tube for blow feed. The springs were to be transported 6 meters away and this was done by blow feeding the same. Sensors were placed on each tube to ensure that the spring was present before singulation took place. Additionally after the escapement / singulation, another set of 4 sensors were placed to check whether the springs had pashed through the blow feed. The complete system with electrical controls was designed and manufactured by Elscint and supplied to a big auto manufacturer in Canada.
