ABSTRACT:
A process and apparatus for regularly and continuously supplying articles to an evacuation conveyor from at least one feed conveyor. The articles are arranged in successive rows on each feed conveyor and are deposited onto the evacuation conveyor which moves the articles in a single longitudinally extending row. The evacuation conveyor is positioned at an acute angle relative to each of said feed conveyors and each of the article is aligned and moved through an angle on the evacuation conveyor which is substantially complementary to the acute angle. The speeds of the feed and evacuation conveyors are adjusted so that the spacing between the last article in a given row deposited from a feed conveyor onto the evacuation conveyor and the first article in a successively deposited row is substantially the same as the spacing between adjacent articles within any row. Specific relationships are given regarding the speeds of the feed and evacuation conveyors to achieve a regular and continuous supply of articles as a function of the spacing between rows on the feed conveyors; the length of the rows on the feed conveyors; the spacing between a given row of products and a following row of products after transfer to the evacuation conveyor; and the spacing between articles within a row. A specific relationship is also given with regard to the minimum width of the evacuation conveyor as a function of the length of a row of articles on the feed conveyors; the length of an article; and the angle between the evacuation conveyor and the feed conveyors.
