Operation
The incoming dry vials (sterilized and
siliconised) are fed through the unscrambler with suitably guided on the moving delrin flat conveyor belt at the required speed of the correct placement below
powder wheel.
The sterilized powder stored in
two powder hoppers is agitated by pair of mechanical agitators for maintaining
consistency and uniform bulk density, each powder wheel having eight ports
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, the doctor blades can also be adjusted from outside without
removing powder hopper. When powder wheel indexes further and remain in the port
due to the vacuum till it reaches just vertically above the vial. 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 container one by one.
It is a double wheel Double track machine, so each powder wheel is filling vials
alternately with double track system. The filled vials are immediately separated
on the conveyor by vial separator and moves further for stoppering operation.
(Different grooves separator can be used which depends on the container diameter
or multiple dosing system.) After separated from vial separator, vials move
further towards rubber stoppering unit and in between it will be converted in to
single track from from double track with the help of suitable guide rails on
machine conveyor.
The sterilized and siliconised
rubber stoppers stored in the vibrator bowl moves vertically to the rubber
stopper chute. The vial is hold firmly between pair or timing belt to pickup
rubber stopper from exit end of the chute. Further the vials are passed between
two pressing roller for tight fit fixing of rubber stopper. After stoppering
operation, vials will be collected in to the Scrambler and move towards sealing
machine for Vial sealing operation.
Salient Future
 |
M.S. Moulded structure duly
powder coated to avoid any vibration, with adjustable screws to adjust conveyor
height as per infeed tunnel.
|
|
|
Total cGMP model.
|
|
|
All parts and assemblies coming
in contact with powder and rubber stopper are made of S.S.316 and easily
removable for mandatory Autoclaving/Sterilisation.
|
|
|
"NO VIAL, NO FILL" System
eliminates wastage of costly powder.
|
|
|
Spring loaded Teflon top seal
for powder hopper reduces the friction between and top seal and avoid chance of
white particle shading during production.
|
|
|
Doctor blade and wiper blade
can be adjusted from outside also without disturbing any production, which saves
lot of time, powder wastage and chances of area condition disturbance.
|
|
|
All assemblies under top plate
are positioned as for easy cleaning or maintenance.
|
|
|
Multiple dosing of injectable
powder or change over of vial size and different fill size is possible by just
changing the vial separator or size of the piston respectively.
|
|
|
All driving is without High
quality imported Gear motor for better machine performance without vibration or
leakage of oil in area floor gear box.
|
|
|
Machine speed can be adjusted
through A.C. Frequency drive, which is time saving and easy to synchronise unscrambler and scrambler speed with machine speed.
|
|
|
Machine is provided with delrin
conveyor belt to avoid sticking of vial on conveyor.
|
|
|
Special clutch devices are
provided on vial separator for safety purpose.
|
|
|
Vibratory bowl for rubber
stoppering unit support to run machine with total claimed speed of machine.
|
