Abstract
The installation according to the invention includes a cabinet for storing objects, apparatus for processing these objects, apparatus for transferring these objects between the storage cabinet and processing apparatus for the same, constituted by mobile containers and fixed containers fixed to the processing apparatus. The mobile containers can be coupled to the cabinet and to the fixed containers in order to carry out the transfer of the object to be processed. The installation also includes apparatus for ventilating the interior of the installation in order to permanently subject the objects to a very clean gas flow. This apparatus can be constituted by fans, by internal filters, or by an external pressurized ultraclean gas source.
Claims33
Installation for the storage and transfer of objects with a view to the treatment or processing thereof in an extremely clean atomosphere, said installation being adapted to be placed in a room having an average cleanness level, said installation comprising:
- (a) storage means for storing the objects;
- (b) processing means for processing the objects;
- (c) transfer means for transferring the objects between said storage means and said processing means, said transfer means comprising at least one mobile container which can be coupled to said storage means and to said processing means and at least one fixed container for the introduction of the objects into said processing means, said at least one fixed container being couplable to said at least one mobile container, said containers comprising at least one filter having an upstream face and downstream face, said containers also comprising means for producing an overpressure within said containers;
- and
- (d) ventilation means for circulating the gas contained within said containers so that the gas traverses said at least one filter from the upstream face to the downstream face thereof,
- (e) said means for producing an overpressure and said means for circulating the gas comprising an intake making it possible to link the interior of said installation with an external pressurized, ultra clean gas source.
