CA 2184007

Apparatus for filling sterile containers is disclosed which defines an elongated but narrow sterile zone in which a number of operating stations are disposed. An elongated vertical wall is carried by an elongated frame and a cabinet type enclosure cooperates with the vertical wall to define the sterile zone. The plurality of operating stations are disposed in sequential relation over the length of the sterile zone, and an elongated container conveyor is disposed within the sterile zone to convey the containers through the plurality of operating stations. The conveyor is vertically oriented, consisting of an endless belt mounted on end wheels that rotate on horizontal axes. Each of the operating stations includes an operating portion disposed within the sterile zone. Actuating means are included for each of the operating stations as well as the elongated conveyor, each of which is disposed outside the sterile zone. Connecting means operably connect each of the actuating means outside the sterile zone through the vertical wall to the associated operating station within the sterile zone. By orienting the conveyor vertically and disposing the various actuating means outside the sterile zone in side-by-side relation, the effective width of the sterile zone is significantly reduced. As a result, the sterile zone is more easily accessed, and also more easily drained after washdown operations. In addition, the sterile zone of reduced size results in an apparatus that is much easier to manufacture and maintain in a sterile state.

Un dispositif de remplissage de récipients stériles définit une zone longue mais étroite comportant plusieurs postes fonctionnels. Une paroi verticale de forme allongée, montée sur un châssis de forme également allongée, définit avec une armoire d'enceinte une zone stérile. Les différents postes fonctionnels sont disposés en série longitudinalement dans la zone stérile où un convoyeur à récipients transporte les récipients de poste en poste. L'ensemble convoyeur, disposé verticalement, est constitué d'une bande sans fin montée sur des roues tournant sur des axes horizontaux. Chacun des postes fonctionnels comporte une partie fonctionnelle située en zone stérile. Tous les actionneurs de chacun des postes fonctionnels ainsi que tous ceux du convoyeur longitudinal sont situés hors de la zone stérile. A travers la paroi verticale, des éléments raccords mettent en relation fonctionnelle avec son poste opérationnel chacun des actionneurs situés à l'extérieur de la zone stérile. La disposition verticale de l'ensemble convoyeur et l'implantation des différents actionneurs à l'extérieur de la zone stérile selon un plan "côte à côte", permet de réduire de façon notoire la largeur effective de la zone stérile. L'accès à la zone stérile, ainsi que son séchage après une opération de lavage, en sont donc facilités. En outre, les dimensions réduites de la zone stérile en font un appareil plus facile à fabriquer et à maintenir en état stérile.
