Feeding of Sharpeners & Erasers
Elscint recently manufactured one more set of vibratory feeding systems for sharpeners and erasers (one set consisting of two vibratory bowl feeders, one in clockwise direction feeding erasers and the one in anti-clockwise direction feeding sharpeners. There were three types of sharpeners and 3 types of erasers which were to be fed in the same bowl feeder with the minimum changeover tooling. Model 630 Vibratory drives were used for this in order to ensure the required speed. Further one extra capacity hopper along with level controller was provided for each of the bowl feeders to ensure optimum loading quantity. From the bowl feeder, the sharpeners and erasers were taken forward through a linear vibrator onto a pushing fixture where each of sharpeners and erasers was pushed around 100 mm by a pneumatic cylinder onto the packing conveyor of the customer for packing. The requirement was for a speed of 150 parts per minute through the bowl feeder and 100 parts per minute along with pushing. The same was accomplished easily as Elscint Model 630 drives are very stable and powerful providing high speed feeding and superb performance. This matched with the excellent build quality and tooling of the bowls, which is the hallmark of Elscint products, ensured customer satisfaction to the level that the customer immediately ordered 8 more sets of equipment for each of his packaging lines.
