Elscint recently manufactured a vibratory bowl feeder for feeding of rectangular rubber

seals having size 12.5 x 9 x 5.50 mm thk in two rows at a particular centre distance. The

requirement was for feeding of 120 seals per minute per row. Elscint used its model 250

for this purpose with a cast aluminium bowl with the tooling being in stainless steel.

Ahead of the bowl feeder, a 700 mm long double linear track was attached to convey the

rubber seals upto the pick up position of the customer. The customer also wanted the

bowl feeder and the linear vibrator completely enclosed with a top polycarbonate cover.

The whole equipment was mounted on a single post stand with an height adjustement of

(+/-) 100 mm. The seals were covered with a particular type of grease which resulted in

them sticking together and coming double. This resulted in the feed rate being very low.

However, Elscint provided an extra moving mechanism which ensured that the joint seals

were disentangled. Due to this the feed rate improved drastically and helped ensure that

all the seals came out of the bowl.
