Ampoule Filling & Sealing Machine

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.

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.
