ABSTRACT:
The invention relates to an automatic packing system including a station at which a serial stream of articles are placed into stacks (one on top of another) or groups and discharged into a transversely moving tray-type package, or the like. The system includes a conveyor belt for transporting the articles, one by one, while they lie in a horizontal plane. The articles are transferred by another conveyor to a station at the end of the conveyor where the articles are stopped by protruding pins, picked up by a vacuum holding device, transferred by lever mechanisms and carried to a loading station where the articles are dropped one upon another in a stacked manner until an appropriate group has accumulated. When the appropriate group has been accumulated, the bottom of the loading station opens to release the stacked group of articles to fall into its tray-type package, which is moved transversely under the loading station in synchrony with the accumulated articles so as to be directly under the group of dropped articles.
