Elscint recently manufactured a bowl feeder for feeding of 4 types of cups and 2 types of baffles. Both these types of components were from separate families and hence separate bowls were required for both these families of components. Elscint Vibratory bowl feeder Model 400 was used for this purpose. Model 400 is a full wave vibrator having rating of 780 VA, drawing just about 4 Amp current. Due to correct design and proper coating, it works very efficiently at a high speed and the noise level too is very less. The Model 400 drive unit too is CE certified for machinery safety, low voltage directive as well as the electro-magnetic compatibility. Orientation required at the outlet for the cups was open side facing sky, however, the cup needed to be first reversed to make it open side facing ground to ensure that burr and small unwanted parts are removed from the cups. Then the cup again needed to be reversed to ensure that the required orientation at the end of the bowl is realized in the “open side facing sky” manner. There were a total of 4 types of cups (diameter 14 mm x 8 mm ht., dia 18 mm x 7.5 mm ht., dia 20 mm x 7.5 mm ht. and dia 25 mm x 12 mm ht). All these parts are fed and even reversed in 360 degrees with the minimum amount of changeover parts and adjustments. A speed or feed rate of 350 parts per minute was achieved. An Elscint cast aluminium bowl Model 400 with Elscinthane PU coating and stainless steel tooling was used for this purpose. Elscinthane PU coating ensures that there is no metal to metal contact and thus reduces the noise level as well as increases the friction, thus further improving the feed rate and performance of the bowl. The life of the bowl too increases due to this type of coating. Further in the same feeder, two types of baffles were needed to be fed. However, the geometry and sizes of the baffles were totally different from that of the cups. One baffle was having diameter 38.5 mm x 2.9 mm thickness with a curved side. While the other baffle had diameter 47.4 mm x 1.75 mm thickness with an internal curve, making it very difficult to orient. For these two baffles, Elscint supplied a separate bowl which could be changed easily. This bowl too was of cast aluminium with Elscinthane PU coating and stainless steel tooling. The baffles too had to be turned around in 360 degrees as they came out naturally with the curve up. Hence, first they needed to be turned in 180 degrees to ensure that the curve side was facing ground. Then again they were turned in 180 degrees to ensure that the final orientation was the curved side up. Speed of the baffles was 60 parts per minute. The bowl feeder was supplied to a customer in Europe. The video of the bowl feeder can be watched at http://www.youtube.com/watch?v=kyJYvIjAUVo
