Injectable Glass Ampoule Washing Machine

Ampoules fed from the infeed tray are received by the infeed feed worm and then transferred to the infeed star wheel. Grippers pick up each ampoule from the infeed star wheel, invert it into the neck-down position over the washing needles, and move it along with the needle bar for washing. Traveling in the neck-down position above the washing needles and moving with the needle bar ensures maximum washing time once the needles enter the ampoule neck. The machine has six different washing stations, each equipped with six needles for optimum washing; the sequence can be adjusted as required. The washer also includes an external wash for thorough cleaning of the ampoules.

At the end of the cycle, the washed ampoules are inverted back to the neck-up position and transferred to the output star wheel. Ampoules received from the output star wheel can be collected on the output tray or pushed into a tunnel. An optional separate pumping station supplies the correct volume of water at the desired pressure. In the absence of a separate pumping station, a re-circulation and siliconization system can be provided on request.

INTERNAL CLEANING: The AVRW is equipped with six internal cleaning stations, each having six cleaning needles, for a total of 36 cleaning needles. Each station is supplied through a pipe connected to the cleaning media-making washing area. This design reduces the risk of particle generation, simplifies maintenance and cleaning, and saves time.

EXTERNAL CLEANING: Three external cleaning stations are mounted in a stationary position above the ampoules and can be easily adjusted for height, angle, and lateral position. Each station receives cleaning media through a pipe connected to the cleaning media-making washing area.

CLEANING MEDIA PRINCIPLE: WFI, purified water, and air cleaning stations are synchronized with the ampoule through reciprocating motion. The design ensures that these media are used only when the needles move in the forward direction. WFI consumption is further reduced by collecting the used WFI in a re-circulating water tank for later use in the pre-washing station.
