Elscint Vibratory Bowl Feeder to feed Bolts, Rivets and Pins in Head Down Position
Usually, parts like bolts, pins and rivets are fed in Head Up or Axial Position (Head leading or trialing) through a Vibratory Bowl Feeder. However, recently, a customer approached Elscint to feed these parts in Head Down orientation. All these parts, bolts, rivets and pins with head were to be fed to the same vision inspection machine and secondly, the number of parts of each type too was very large. Elscint took up this challenge and provided a bowl for feeding of the bolts, which were of M10 size with the head being either regular or else extra long on one side. There were a total of 5 types of bolts ranging between M10 x 40 mm to M10 x 70 mm length. For the rivets, which were having head diameter 15 mm x 20 mm to 30 mm length, Elscint provided a separate changeover bowl. The linear track of 800 mm ahead of the bowl feeder was kept the same for both the types with proper adjustment. Lastly, the pins with heads were having head diameter 5 mm to 10 mm and lengths from 30 mm to 120 mm. For these pins, again a separate change over bowl was provided with a separate linear track. The speed required was more than 150 parts per minute. This was easily achieved for all the parts except the 120 mm length pins, for which the speed achieved was 60 parts per minute. The parts were to be fed onto the glass indexing plate of the customer for inspection from all sides. You can watch the video of the bowl feeder for feeding long pins.
