Elscint recently manufactured and supplied a Vibratory bowl feeder for feeding of Engine Valves having head diameter from dia 20 mm to dia 48 mm with length varying between 60 mm to 140 mm in head down orientation. The tendency of the engine valves is to come up in axial orientation, either head forward or behind. Making them in head up orientation is easy as a single slot in the wall makes them head up. Making them head down requires a different type of orientation tooling which Elscint provided in this bowl feeder. The tooling was made so versatile that all the above sizes could be accommodated without any changeover. This resulted in ease for the operator when sizes are changed. The requirement was to feed the valves for laser welding. Hence, Elscint offered a indexing table where a single engine valve was kept ready for laser welding. After the laser welding operation, the valve was released into a bin. Elscint provided the complete system, including a linear vibrator to move the valves from the bowl feeder onto the indexing table, a singulator and pusher to push the valves onto the indexing table. Thereafter, the valves were taken to the welding position. Here too, Elscint provided mounting arrangement for the laser welding machine with X-Y and Z adjustment which could be used as the valves sizes change. After the laser welding, on the next station, the valves were released into a bin. A cycle time of 30 parts per minute was achieved. The complete system was controlled through a Siemens make PLC.
