Feeding of Electrical Switch Part for inspection

Elscint, recently completed a project where the requirement was to feed Plastic part of an electrical switch having sizes 40 mm length x 33 mm ht. in a bowl feeder. There were two parts which were slightly different in dimensions but due to this the orientation of both was different. The requirement was to feed both the parts in a same bowl feeder without any changeover. The part being the electrical switch, the customer did not want any scratches on the same due to rubbing on the bowl surface or due to contact between two parts. Additionally, a total of 2000 parts was to be accommodated in the bowl. Hence, Elscint recommended a slightly bigger bowl feeder for this requirement, namely, Model 630 with step / cascade type bowl a 1000 mm diameter. To ensure that the noise level would be within permissible levels, a noise enclosure lined with acoustic foam was provided for the complete bowl feeder. Ahead of the bowl feeder, a 1200 mm long conveyor was placed with variable drive on which vision inspection of the parts was to be conducted. The electrical panel was provided on a separate stand to isolate the same from vibrations of the bowl feeder. The conveyor too was completely covered to ensure that all safety requirements are taken care of. A speed of more than 70 parts per minute was achieved as against 50 parts per minute required by the customer.
