Title:
SINGLE BALL SEPARATING DEVICE AND SINGLE BALL SEPARATING METHOD
Document Type and Number:
WIPO Patent Application WO/2008/062710
Kind Code:
A1
Abstract:
Single ball separating device and method which solve a bonding-to-slope problem that
is posed when a single ball is separated and collected out of a mixture of a single
ball, coupled balls and an abnormal ball by slope rolling, and which are provided
with characteristics of efficiently separating a single ball from a mixture
of a single ball, coupled balls and an abnormal ball. The single ball separating
device comprises a supply device for supplying balls, a slope surface along which
balls are rolled down, and a collecting unit for collecting balls jumping out
from the slope surface, all being installed in an airtight chamber, wherein the
airtight chamber has a pressure reducing device for keeping the interior of the
airtight chamber at 1000 Pa. The single ball separating method comprises, in
an airtight chamber reduced in pressure to below 1000 Pa, supplying balls from the
supply device to the slope surface to allow them to roll down along the slope surface,
separating them according to the speed difference and/or direction difference
of the balls, and collecting them at the collecting unit.
