CPLFRS Automatic Vial Filling with Rubber Stoppering Machine is a compact model used for filling and rubber Stoppering of Injectable liquid into vials.

The incoming dry vial (sterilized) are fed through the Un-scrambler and suitably guided on the moving delrin slat conveyor belt at the required speed of the correct placement below Filling unit.

The filling unit consists of Filling Head, Syringes & Nozzles which are used for liquid filling. The syringes are made of S.S. 316 construction and both, glass as well as S.S. syringes can be used. A Star Wheel is provided which holds the vial during filling operation. A sensor is provided for ''No Vial, No Filling'' operation. Syringes are mounted on eccentric block and driving through bottom main gear box. Volume can be either increased or decreased by increasing or decreasing stroke length of piston as per filling size. Syringes is having non return valve for sucking and delivering situation to avoid volume variation. Liquid will reach to filling nozzles through silicon transparent pipe. Nozzle will be having Up and Down movement with help of cam mechanism and it will come down when vial will be hold by star wheel for filling operation and starts filling when it starts to move up and after completion of filling operation, star wheel delivers four/six vials together on conveyor for rubber Stoppering operation.

Stoppering unit consist of Star wheel, Vibrator unit and Bowl. The sterilized/autoclaved rubber stoppers stored in the vibrator bowl moves vertically to the rubber stopper chute. The vial is hold firmly by star wheel, which will be in continuous rotary motion and vial which is coming from filling unit get in to star wheel and move in rotary direction along with star wheel, during movement it will pick up the rubber stopper from the exit end of the chute and rubber stopper will be pressed by fix pressing roller, which is spring loaded. Then vial further move on conveyor and collected on out feed star wheel for next sealing operation.

The incoming dry bottles containers are placed manually below the feed nozzle and set volume is filled through volumetric cup set fitted with adjustable disc guide. Machine is semi automatic so output will totally depend on operator efficiency. Volumetric cup filling machine is single discharge for dosing system is specially designed to best suit powder/granulate dosing mechanism. Machine is also available with automation features.

This type of filler is best suited for liquids with very thin viscosities that do not change with ambient temperature or with batch variation. This machine is also suited for applications where recirculation of the liquid in the fluid path is not desirable. Although this type of filler is used predominantly on products that do not foam, foam may be limited and controlled by subsurface/bottom-up-fill capability.

EXAMPLES:

Water, solvents, alcohol, specialty chemicals, paint, inks, corrosive chemicals i.e. acids and bleach

ADVANTAGES:

This is the most economical type of filling machine for a limited range of applications. It is especially well suited for corrosive chemicals.

Automatic Vacuum Powder Filling machine is a compact model used for filling of Powder in to Bottles / containers, The incoming dry container sterilized are fed through the in feed Un-scrambler and suitably guided on the moving S. S. / delrin flat conveyor belt at the required speed of the correct placement below powder wheel.

The powder is stored in powder hopper is agitated by pair of mechanical agitators for maintaining consistency and uniform bulk density. The 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. 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 vertically above the container. The time dose of Compressed air (Nitrogen Gas), sterilized low pressure air sequentially flushes out powder from the port of powder wheel in to the container one by one. The filled container is immediately separated on the conveyor by vial separator and moves further for operation. (Different grooves separator can be used which depends on the container diameter or multiple dosing systems).

The sterilized ampoule tray can be directly loaded in to slant hopper of the unit. The synchronized star wheel Delivers ampoules, one by one on moving eccentric ampoule rack in single or two's or four's. During the stoppage of rack sequentially pre-gassing Filling, post gassing, pre heating (for single and double head only) and final Sealing/annealing is achieved. At the end to the rack, optional synchronized pusher Pushes out ampoules in to tray in vertical position.

The basic unit fitted with parts suitable for any size of Ampoule and any one fill size syringes. In the event of change over of each size of Ampoule, following change parts are required.

The filling system includes filling syringes, made from stainless steel, pre & post gassing arrangements as well as mechanical "No Ampoule, No Filling" device. Filling is affected by aspirating filling product through the syringes, passing it by positive displacement through the non return valves, filling tubes and filling needles in to the ampoules. Fine setting of each filing syringe is possible. The machine is suitable for filling range from 1 ml to 20 ml. "No ampoule, No filling" system is advantageous to save the costly filling liquid.

The sealing station is composed of the ampoule revolving station, sealing burners as well as draw-off jaws. The regulations of burner flames are made easier with the knob.

The machine can be easily inspected and better accessed from the both the sides. The driving and controlling elements are protected from splinters, product spillage and jets of water. All the parts coming in contact with the filling liquid are made out of stainless steel 316 and can easily be cleaned and sterilized.

The ampoules which are to be treated are fed from ampoule sterilization boxes to an inclined charging hopper. Alternatively, customer can make arrangement for feeding the ampoules directly from sterilized tunnel. Through the charging hopper the ampoules are passed in to ampoule feeding Wheel, which in turn transfers the ampoules positively to the ampoule carrying rack.

Ampoules at a time are transported to the various processing stations. The ampoule carrying rack carries the ampoules at an angle of 52 degrees to the vertical, stroke wise. Two centering racks lift the ampoules from behind out of ampoule carrying rack for inert gas treatment and filling and sealing operation. The precision transport system ensures exact centering of ampoule necks at each working station.

At the filling station, ampoules are filled accurately, at a time depending on no. of syringes. Filling is affected by aspirating filling product through the syringes, passing it by positive displacement through the non return valves, filling tubes and filling needles, in to the ampoules. Filling in the stationery position and exact centering of necks at the filling and gassing stations guarantees filling without moistening ampoules necks and uniform, safe closures.

The sealing station is composed of the ampoule revolving station, burner station as well as draw off jaws. In the ampoule revolving station, the ampoules are rotated round its longitudinal axis. At sealing station, the ampoule necks are gripped by the draw off jaws and sealed when adequate plasticity of glass has been reached, the glass splinters are collected in the waste box.
