Elscint recently manufactured and supplied two vibratory bowl feeders for feeding of stainless steel balls. One unit was to feed a dia 5.5 mm ball while the other one was to feed a dia 8 mm ball. The customer wanted a poka-yoke to ensure that the dia 5.5. mm ball would not be fed in the one designed for dia 8 mm ball and vice versa. The speed required was just 12 balls per minute for both the equipments. However, the customer required singulation for the same i.e. one ball to be released on receipt of a signal. This required an highly accurate singulation mechanism. This was provided with the help of a Festo make cylinder. Further good quality sensors were also required to ensure, the bowl feeder is switched off once the tube carrying the balls is full and to provide a signal to the customer once a single ball is singulated. For both these, a ring type sensor was used. The equipment was completed within the customers timeline and successfully installed at the customer’s place. You can watch the video of the vibratory ball feeder. .
