Abstract

System (10) for automatically conveying photosensitive cargo containers (15) through a storage compartment (14) of a vehicle, preferably a trailer (12) and selective environmentally controlled enclosures (32,40,42) comprises a conveyor device (18) positioned in the storage compartment (14) that cooperates with interconnected conveying device (34) in the enclosures (32,40,42). Devices are provided for aligning and positioning the rear exit end (16) of vehicle (12) snugly against the entrance port (30) of a proximally positioned enclosure (32). A system control device (100) connecting the conveying means (18) and conveying device (34) enables the cargo containers (15) to be automatically conveyed from the vehicle (12), through the entrance port (30) and into the proximal enclosure (32).

Claims

1. A system for conveying cargo containers in the absence of contamination through a vehicle having a storage compartment defined by a first floor portion, a first ceiling portion and first sidewalls surrounding said first floor and first ceiling portions and then through at least two environmentally controlled enclosures:

each said environmentally controlled enclosures having a second floor portion, a second ceiling portion and adjoining second sidewalls surrounding said second floor and second ceiling portions, said system comprising;

an entrance abutting said vehicle for positioning at least one of said at least two enclosures proximate to said storage compartment of said vehicle, said entrance port comprising means for sealing an exit end of said vehicle and said at least one of said at least two enclosures against the ingress of particulate contamination;

a first means for precisely aligning and snugly positioning said exit end of said vehicle with said entrance port;

a second means operatively associated with said vehicle for conveying said cargo containers from said storage compartment of said vehicle, through said entrance port and into said proximate enclosure;

a third means in the proximal enclosure for conveying the cargo container in a predetermined direction so as to selectively load or unload the cargo containers in said proximal enclosure or into said storage compartment of said vehicle; and

,

a system control means cooperatively associated with said vehicle and said environmentally controlled enclosures for automatically actuating said second and third means once said aligning and positioning means has been confirmed.

2. The system recited in claim 1 wherein each of said environmentally controlled enclosures comprises a conveying means for transporting said cargo container therein, each of said conveying means and said second conveying means associated with said vehicle being provided with means for communicating with said system control means.

3. The system recited in claim 2 further comprising a fourth means positioned in at least one of said environmentally controlled enclosures and cooperating with the conveying means therein for cleaning said cargo container therein.

4. The system recited in claim 1 wherein said first means comprise a predetermined arrangement of guides and ramps cooperating with said vehicle, said ramps and guides being positioned so as to enable said vehicle to form an intimate seal between said exit end of said vehicle and the entrance port of at least one of said environmentally controlled enclosures.

5. The system recited in claim 1 further provided with a cargo container control means for detecting and reading bar coded indicia from the cargo container and signalling the system control means.

6. The system recited in claim 1 wherein said controller means comprises a selector switch for determining whether to load or unload cargo the containers from said vehicle.

7. The system recited in claim 6 wherein said controller means further comprises a timer means for selectively conveying said cargo containers at predetermined intervals to any one of said enclosures.
