Elscint recently manufactured and exported 7 complete feeding systems to South Africa. Each system consisted of a vibratory bowl feeder having two outlets, a linear vibrator, again with two outlets with a pneumatic escapement on each of the outlets. For extra loading capacity, a hopper too was supplied with each system. Elscint’s patented pneumatic escapement was used in this case with Festo make cylinders and reed switches. Six of the parts being fed were automobile plastic clips. There were a total of 3 types of clips which needed to be fed through 6 bowl feeders, with some clips required in multiple sets. The speed required was 30 parts per minute per outlet. Elscint could achieve a speed of 60 parts per minute per outlet. The scope of supply included the bowl feeder, linear tracks with a sensor to start / stop the vibrator along with the controller and hoppers with level controllers. Each of the sets was mounted on a separate base plate. The bowls were made of Cast Aluminium and the tooling was made of stainless steel and coated with Elscinthane PU coating. A particular centre distance too was required to be maintained between the two outlets.
You can watch the video of one of the clip feeders here and of one more.
The 7th bowl feeder was for a rectangular steel metal part which was required to be oriented in a lengthwise direction with the flange down. This too was supplied with a linear track. In this case, a cylindrical stainless steel bowl was used wherein the orientation was done on the outer track of the bowl. Further overflow provision was provided an a 800 mm long linear track was added with a pneumatic singulator at the end for ease up of pick up. This bowl too was coated with Elscinthane PU coating so that the metal to metal contact between the metal surface of the bowl and the metallic parts was eliminated and thus the noise was reduced.

The bowl feeders were completed before the committed delivery time and shipped to South Africa.
