Feeder Description & Specifications
Overview of the FR-20 & FR-30
FR-20 vs. FR-30
The FR-20 & FR-30 Centrifugal Feeders unscramble, feed and
orient product. Simply put, it delivers aligned product. Except for
obtainable rates and the size of product, the FR-20 and FR-30
function identically. Generally, the FR-30 is used to handle larger
product or achieve higher output rates.
Operation
Step 1ÑThe Feeder Accepts Your Product.
Every FR-20 and
FR-30 operates in the same basic way. The feeder accepts product
from a separate bulk supply hopper or prefeeder. Product drops
randomly into the bowl, a few at a time. (Shibuya Hoppmann
centrifugal feeders function best when product is carefully metered
from bulk by a prefeeder.)
Step 2ÑThe Feeder Loads and Qualifies Your Product.
After
dropping into the bowl, product in the desired orientation is
pushed up the stationary ramp. This process may be assisted in
some applications by compressed air. After the product has been
pushed up the ramp, it is loaded onto the moving rim of the bowl.
The rim moves the product past mechanical, pneumatic and/or
optical qualifiers which reject product that are not in the desired
orientation. Improperly oriented product are recirculated.
Step 3ÑThe Feeder Delivers Your Product.
Finally, product
moves off the bowl's rim and out of the feeder in the proper
orientation, in a rapidly moving and in a randomly spaced stream.
Shibuya Hoppmann centrifugal feeders deliver product almost
immediately, so parts simply don't have time to get scuffed up.
Rate
Shibuya Hoppmann feeders typically handle product at rates
between 20 and 2000 parts per minute. Your particular product’s
characteristics and your desired production speed will affect the
output rate.
