ABSTRACT:
A method and apparatus for modified atmosphere packaging uses a rotary conveyor to transport a plurality of trays to be packaged between a plurality of stations in a circular arrangement. The trays may be loaded onto a receiving platform by depositing them over movable beds which can reciprocate downwardly in order to permit the trays to be removably held inside slots in a removable platform. Since the platform is removable from the conveyor, it may be centered in any particular station by lifting the platform from the conveyor and guiding it into a precise alignment at a particular station. The package may then be filled, its atmosphere replaced with one lower in oxygen content, and then the desired atmosphere sealed within the package. This can be done in the continuous fashion so that the film is severed from a continuous web. Advantageously, the cutting blades reciprocate with respect to a heat sealing apparatus inside an enclosed environment wherein the cutting blades have internal cooling means to prevent distortions caused by overheating. The various connections for gas and vacuum supply may be quickly disconnected, and an entire station may be changed through the use of quick disconnect connections of the apparatus of the station to a support. The unloading proceeds generally as the reverse of the loading process wherein the trays are pushed upwardly from the platforms and then slid outwardly onto a conveyor.
