Innovative Usage of Vibratory Bowl Feeders – “O Ring” Stacking Machine
Many times components are required in a stacked manner. To cater to this requirement, Elscint has developed an automatic stacking machine for stacking of O Rings. Various sizes of O Rings can be stacked in the same machine with some changeover tooling. O Rings having diameter from dia 8 mm to dia 60 mm can be stacked. Larger sizes are also possible, in case of requirement. The O Rings move upwards on the track of the bowl and are lowered into a metal magazine in front of the Elscint vibratory bowl feeder. Metal magazines, totaling 6 to 12 in number depending upon the component size are mounted on an indexing table. A sensor is mounted to sense the component level onto the metal magazine. When the components are filled upto the level sensor, then the Elscint vibratory bowl feeder is switched off and the indexing table moves to the next stage, bringing an empty magazine at the loading station. At this point the Elscint vibratory bowl feeder starts again and stacking operation continues.
The basic machine works with electrical controls while a PLC controlled version is also available. The indexing table too can be either mechanical or pneumatically operated. The advantage of this machine is to eliminate the need of stacking of O Rings manually. With the help of this equipment, the O Rings stacking can be made an off line activity with the stacked O Rings available for usage as an when required. Similarly any component having a hole in it like a bearing ring, cage, washer etc can be stacked in this machine.
