Elscint Rotary Feeder for WFIs / Respules
There are certain parts which cannot be properly fed in a vibratory bowl feeder at a high speed and hence a Rotary / Centrifugal Feeder (motorised feeder) is required. For a recent project, Elscint manufactured two large Rotary / Centrifugal Feeder for feeding of WFI / Respules having sizes from 20 mm x 115 mm to 135 mm x 145 mm. There were single, double, triple and multiple sets of respules in this, upto 7 respules. These were joint and needed to be fed together, making the 7 respules upto 135 mm width x 145 mm length. The thickness too were different, making it more complicated. The speed required was between 100 to 150 respules per minute depending upon the respule size. This orientation required was lengthwise feeding. Hence, Elscint proposed two Rotary / Centrifugal Feeders. Model RF 1500 which is a double disc Model was used with a size of around 1.5 x 1.5 mtrs. In case of a Rotary / Centrifugal Feeder, one cannot load more than a few components at one time, hence, Elscint proposed a large 150 ltr. Vertical Elevator. This ensured that 2000 WFI / Respules were stored in the hopper of the elevator. The parts were loaded in the elevator. Once the level of parts in the Rotary Feeder went down, the Hopper elevator would start and stop once the particular set level was reached. This was done based on a level sensor inside the Rotary Feeder. A long gravity chute was provided to match the outlet with the belt conveyor of the customer, which took the parts further to the packing machine of the customer. The equipment was completed at Elscint works in Bhosari, Pune and shipped to the customer in Japan The equipment was manufactured with superior build quality which is the hallmark of Elscint products. This being a pharmaceutical requirement, all the parts were made in stainless steel with mirror polishing. The gear boxes used were all Elscint makes with Danfoss make VFDs used in the panel along with LOTO provision for the electrical as well as the pneumatic panels. One Rotary Feeder was made suitable for respules having 1, 2, 3 and 4 sets where the second one was for 5 to 7 sets joint together.
