OPERATION
From the
sterilizing tunnel the empty sterilized vials are routed to the infeed turn
table. Guides are provided in the turn table which properly aligns the empty
vials and passes it to the conveyor. The conveyors takes the vial to the filling
unit. A chamber type arrangement is provided for the pre gasing of nitrogen into
the vials. The flushing of nitrogen takes place before the filling unit. No vial
no filling sensor is provided to avoid the wastage of costly powder. The vials
are held under the powder wheel by a pair of timed vial separators. The timing
of the vial separator are adjusted in sequence with the intermittent motion of
the powder wheel.
This machine is equipped with canister loading arrangement in which the canister
is fitted on top of the powder hopper. From the powder hopper the powder is
drawn by vacuum in to the powder wheel. Vacuum is applied through the nylon tips
filter which is fitted on top of the piston inside the powder wheel. This piston
retains the powder during indexing till it reaches exactly above the vial neck.
Instead of the front facing of the powder wheel this machine has side facing.
The conveyor moves under the powder filling unit. The powder wheel consists of
12 ports instead of 8 port standard powder wheel.
When the vial is held in position by the vial separators a signal is relayed to
the solenoid valve in the powder dosing system. This solenoid activates vacuum
which holds the powder in the port of powder wheel, duing the rotation at the
lowest end the outlet port is connected with compressed air / nitrogen and
changes to pressure. The pressure forces the powder out of the port into the
vial positioned directly below the powder fill wheel. The vial separators then
rotate and the vials are forwarded on the conveyor towards the vial liquid
filling unit.
A separate forcep type conveyor is provided for the eight head vial liquid
filling unit. Individual drive system is provided for this conveyor. Here at a
time eight vials are gets filled with liquid. Here the vials are moving and
along with the vials the diving nozzles also moves along with the vial resulting
in the pouring of liquid into the vial. In this system the syringe rotates 180°
. This system ensures that you get a perfect accuracy while filling.
In this machine you can use powder filling and liquid filling together or you
can use any one (i.e. Either powder filling or liquid filling). All the
operations are controlled through plc system. Post gasing arrangement is
provided at the rubber stoppering unit
After filling the vials moves towards the rubber stoppering unit. The sterilized
and siliconised rubber stoppers are stored in the vibrator bowl. From there the
rubber stoppers moves veritically to the chute. A fibre optic sensor is provided
in the chute which shuts down the machine when there is no rubber stopper in
chute during the operation. The vial is hold firmly between pair of timing belt
to pickup rubber stopper from exit end of the chute. Further the vials are
passed between two pressing roller for tight fixing of rubber stopper. After the
rubber stoppering the vials moves towards the next operation of sealing.
