Innovative Usage of Vibratory Feeders -Elscint Vibratory feeding systems for feeding Uranium Pallets

by Monish Shete 27. July 2015 02:08

Elscint recently manufactured two sets of vibratory feeding systems for feeding of uranium pallets. There were two bowl feeders per set, one to feed dia 5.6 x 6 mm pallets while the other was for feeding of dia 5.6 x 7 mm pallets. One type of pallet was to run at one time. Thereafter, they were to move on a 1500 mm long linear track. However, the first track was of 1100 mm length and the second, mounted on a separate linear vibrator was to be of 400 mm length. The first track was laser marked with a scale on both sides to ensure that the operator knows at what level the pallets were filled. There were provisions made for fixing stoppers and gauges at various points as per the customer request. Further, for ease of operator usage, the two bowl feeders were kept on an X-Y Slide provided with a handle to ensure ease of movement / changeover. The uranium pallets being radioactive, the complete system was to be kept in an enclosure with a maximum opening of 220 x 220 mm and hence, one more requirement was to ensure that the dimensions of the equipment were such that the complete unit, in semi-assembled state, would fit in the above mentioned opening. The electrical panel was housed in a separate control box with a foot pedal provided for stopping of the equipment. 

Innovative Usage of Vibratory Feeders - Elscint Vibratory Bowl Feeder for feeding plastic rivets in 6 rows

by Monish Shete 13. July 2015 11:40

Elscint recently manufactured a vibratory bowl feeder for feeding of plastic rivets in 6 rows. The rivets were small ones, having dia 10.60 mm x tail dia 6.40 mm x 12.30 mm ht. The requirement was to feed the rivets in 6 rows at a centre distance of 50.47 mm at various uneven points at a speed of 60 parts per minute per row. Elscint recommended its Model 400 HD with Linear Vibrator Model Elscint II HD. Model 400 HD has a bowl diameter of more than 700 mm ensuring a lot of loading capacity, eliminating the need of a separate hopper and level control. A speed of between 60 to 120 parts was observed in the various rows. A major requirement in case of multiple outlets is that there should be proper overflow arrangement to ensure that once a particular track is full, the excess rivets are either diverted to another track or fall back into the bowl. Elscint ensured that this was taken care off. The rivets being white in colour, Elscinthane coating was provided on the bowl to ensure that they do not get coloured or dirty during usage in the stainless steel bowl. The equipment was supplied to a customer in Canada and hence was made to work on 110 V / 60 Hz input power. Confirmation videos were sent to the customer for his approval and then the system was packed and dispatched by air freight mode to Canada.

by Monish Shete 6. July 2015 08:58

Elscint recently completed an eight vibratory bowl feeder order from a reputed machine builder. The machine builder was building a machine to assembly 12 parts of a faucet. All the parts were of plastic and of various shapes and sizes. Top cap and certain other parts were easy to orient but some like the “main body” and “nozzle” were most difficult as there was no way to hold the same. Further, along with each bowl feeder, a linear track of suitable length was supplied with auto-switch off mechanism dn mounting arrangement. The customer was mounting all the bowl feeders on his machine and hence each one was supplied on a base plate. A non-vibrating portion at the end of the linear track was provided for each unit to ensure that the customer’s pick and place mechanism could pick up the same easily without any accompanied vibrations. For ease of the customer, Elscint supplied 5 systems within 6 weeks of the order and balance after 12 weeks when rest of the assembly machine of the customer was ready.

by Monish Shete 23. June 2015 05:16

Elscint recently provided an auto loading feeding system to a reputed Duplex Grinding Machine manufacturer for feeding of bushes having dia 14 mm x 30 mm length to their duplex grinding machine. The bush ends were to be ground and hence the orientation required was “rolling”. The bushes used to come in axial direction in the bowl feeder and hence Elscint provided a special mechanism to ensure that the bushes stand up and then the same were twisted in a gravity chute to make them rolling. Proper poka yoke was provided to ensure that the components come only in the right direction. The scope of supply included, a stand to mount the vibratory bowl feeder, twisted gravity chute, noise enclosure, level control to provide indication about less parts in the bowl and a control panel with isolating transformer as the customer provided 3 Phase supply from their machine. Elscint not only supplied the equipment on time but also provided commissioning of the same at the customer’s factory. 

Elscint provides Auto Loading Feeding Systems for length shafts for a reputed Centreless Grinding Machine Manufacturer

by Monish Shete 14. June 2015 11:07

Elscint recently provided auto loading feeding systems to a reputed centerless grinding machine manufacturer for feeding of long length shafts for centreless grinding machines. The length of the shafts was                                                     between 95 mm to 120 mm but one side of the shaft was having a small chamfer which required orientation. As this orientation was not possible in a vibratory bowl feeder, Elscint recommended an Auto Loading Feeding System. The diameter of the shaft was between 8 mm to 12 mm. The equipment consisted of a pneumatic lifter unit and a belt conveyor for further feeding of the shafts to the grinding machine. The shafts had to be aligned and kept on an inclined table, from where a pneumatic cylinder singled them out and fed the shafts to a belt conveyor which further fed them to the centreless grinding machine. Proper synchronizing sensors ensured that the equipment worked without any manual intervention. Options provided included an X-Y adjustment of (+/-) 50 mm on either side, which is especially useful for wheel dressing. Height adjustment of (+/-) 50 mm too was provided to ensure that the feeding system was compatible for shafts of various diameters. The conveyor speed was kept variable by providing a VFD drive. Elscint supplied two similar systems to the Grinding Machine Manufacturer and even commissioned the systems by integrating the same with their machine at the works of the manufacturer proving the same in front of the end customer. You can watch the video of the Auto-Loading System for longer length shafts for Centreless Grinding Machines.

Innovative Usage of Vibratory Feeders - Elscint Vibratory Bowl Feeders to feed threaded stopper and hub cover

by Monish Shete 23. May 2015 06:35

Elscint has developed a lot of expertise in manufacturing vibratory bowl Feeders for blood bag components. The main requirement is for feeding of parts like the threaded stopper and hub cover, which go into the blood bag as well as saline bags. Orientation and feeding of the “threaded stopper” is quite easy but the “hub cover” is quite difficult to orient and secondly, getting the required speed / feed rate is a challenge. However, Elscint has developed a very modular design for its bowl which makes it easy to achieve various speeds. Speeds of upto 200 parts per minute are possible. Further, being medical parts, a medical grade bowl made of stainless steel with proper welding and polishing is required. In case of a recent order, the orientation required for both the parts was “rolling with pointed side towards bowl centre”. Additionally, Elscint provided a gravity chute with a sensor to ensure that the bowl feeder got switched off once the chute got full. The bowl feeders were supplied along with Frequency Controllers of suitable rating.
