Abstract

A dynamic bladed cross~mixing and blending mechanism 1 is proposed which is particularly useful in a development system of a xerographic reproducing machine. Developer material comprising carrier particles and toner colorent particles slide down an inclined chute 2 and are received by a rotating cylinder having blades 3 and holes 4. The blades 3 extend from one end of the cylinder to the other and are inclined with respect to the axis of the cylinder. The holes 4 in the cylinder wall con~nunicatewith the blades 3 on the left side of the cylinder so that develop~ er material received by the blades passes through the holes into the interior of the cylinder. In the apparatus shown the developer material slides along the blades toward the viewer as it is received by the blades. This creates a cross-~mixingeffect. A stationary liner 5 is provided about the lower portion of the interior of the outer cylin~ der to prevent developer material from falling out of the cylinder. A paddle wheel 7 is arranged inside the outer cylinder. It rotates counter to the outer cylinder for blending the developer mixture.

A dynamic bladed cross~mixing and blending mechanism 1 is
proposed which is particularly useful in a development
system of a xerographic reproducing machine. Developer
material comprising carrier particles and toner colorent
particles slide down an inclined chute 2 and are received
by a rotating cylinder having blades 3 and holes 4. The
blades 3 extend from one end of the cylinder to the other
and are inclined with respect to the axis of the cylinder.
The holes 4 in the cylinder wall con~nunicatewith the
blades 3 on the left side of the cylinder so that develop~
er material received by the blades passes through the holes
into the interior of the cylinder. In the apparatus shown
the developer material slides along the blades toward the
viewer as it is received by the blades. This creates a
cross-~mixingeffect. A stationary liner 5 is provided
about the lower portion of the interior of the outer cylin~
der to prevent developer material from falling out of the
cylinder. A paddle wheel 7 is arranged inside the outer
cylinder. It rotates counter to the outer cylinder for
blending the developer mixture.

The developer material then flows out of the outer cylin~
der through the holes 4 on the right hand side and slides
along the blades 3 into a developer sump or other desired
location. The blades 3 on the right side of the cylinder
are inclined in the opposite di...
