The
incoming dry container (sterilized
and siliconised) are fed through the
infeed Turn Table with suitably guided
on the moving delrin flat conveyor
belt at the required speed for feeding
to the feed worm for correct spacing
between two bottles and get enter
into the infeed starwheel, which will
be transferred below funnel, 16 nos.
of funnel is mounted on round plate
and powder filling head is mounted
from centre pipe, which gives the
flexibility to adjust position of
wheel as per requirement and consumes
less space on machine. Machine will
be having a lifter assembly on base
of bottom plate, when bottle come
below funnel, bottom platform will
lift the bottle and insert the bottle
tight fit inside funnel. The sterilized
powder is stored in to powder hopper
is agitated by pair of mechanical
agitators for maintaining consistency
and uniform bulk density, powder wheel
rotates at the pre determined speed
below the powder hopper with practically
no clearance. Powder wheel consist
of Piston in each port and behind
the powder wheel vacuum plate is provided
there is no clearance between powder
wheel and vacuum plate due to back
spring pressure. Precise volume of
powder is sucked in to the port of
powder wheel during vacuum according
to the piston length different fill
size can be achieved. The excess powder
is doctored off by a doctor blade,
now doctor blades can be adjusted
from outside also without removing
powder hopper. When powder wheel indexes
further and remain in the port due
to the vacuum till it reaches just
vertical position. The time dose of
Compressed air, sterilized low pressure
air or Nitrogen Gas sequentially flushes
out powder from the port of powder
wheel in to the funnel. Funnel will
be equipped with square rod to break
the solid slug of powder and powder
will start to fill inside bottle,
which is moving along with funnel.
In this model Bottle is getting around
5 to 6 second filling time. Bottles
further move with funnel and reaches
to exit starwheel, which is infeed
starwheel for eight head ROPP cap
sealing machine, while rotating with
starwheel bottle picks up the cap
from exit end of chute, ROPP caps
kept in orientation unit, automatically
orient caps in right direction before
entering into delivery chute. And
Bottle is entering below the sealing
head, consist of total four rollers.
Two rollers properly Skirts, Spins
and Seals the cap and simultaneously
another two roller performs perfect
threading according to bottle neck
diameter. After sealing operation,
sealing head moves upward with help
of cam and bottle enters into exit
starwheel. Move further on conveyor
belt for next operation. |
