Abstract

Abstract A method and apparatus for using a vibratory type conveyor means for processing discrete articles, for example elongated articles or produce, including grading the articles by length. Readily removable and adjustable tray means are carried by the conveyor means in spaced relation to a bottom wall of the conveyor means, the tray means comprising a plurality of tray sections of selected configuration and design depending upon the treatment of the article. Tray sections are designed to longitudinally orient elongated articles, certain of said tray sections having their trailing discharge edges spaced longitudinally and vertically from the adjacent end portion of the succeeding tray section. The tray section is provided with longitudinally extending fingers to span the space between adjacent ends of tray sections for retaining orientation of those articles which pass over said space, permitting articles of less than a selected length to fall to the conveyor wall there beneath for separation purposes. A tray means including a plurality of tray sections of different design and configuration for varying the treatment of articles transported by said conveyor means. A vibratory conveyor means having a resilient support means and drive means therefor to provide an efficient versatile material handling apparatus.

Dependent Claim 169 words
In a vibratory conveyor including a conveyor section with a bottom wall, resilient means supporting said conveyor section, and drive means for imparting vibrations to said conveyor section and including a drive shaft supported from the conveyor section and a stabilizer arm for the drive shaft, the combination therewith of: means carried by said conveyor section above said bottom wall for conveying and treating discrete articles and including means for orienting said articles longitudinally with respect to the conveyor section, said orienting means including orienting trays spaced from said bottom wall and positioned across said conveyor section, adjacent orienting tray portions being spaced longitudinally and vertically relative to each other to provide a longitudinally extending gap zone of selected length, and finger means extending over said gap zone to maintain orientation of oriented articles being transferred from one tray portion to another tray portion, oriented articles of selected length falling through said gap zone for travel along said bottom wall of the conveyor section to a selected discharge point.
Claim 3
Dependent Claim 28 words
In a conveyor as stated in claim 1 including tray means having perforations therein on said conveyor section for removal of unwanted substances mixed with said oriented articles.
Claim 4
Dependent Claim 19 words
In a conveyor as stated in claim 1 including means for separating oriented articles in accordance with their width.
Claim 5
Dependent Claim 114 words
Means for separating articles according to at least one dimension and including vibratory conveyor means to move said articles along a path, comprising: a plurality of tray members arranged in tandem relation to define a pathway; certain of said trays having a bottom wall provided with means for longitudinally orienting an article; said bottom wall including longitudinal corrugations; adjacent transverse edges of bottom walls of adjacent trays being spaced longitudinally and vertically selected distances; and means extending from the edge portion of the uppermost tray over the space between said trays and over the adjacent edge of the lowermost tray to laterally restrict movement of articles being separated at the gap between said trays.
Claim 6
Dependent Claim 114 words
Means for separating articles according to at least one dimension and including vibratory conveyor means to move said articles along a path, comprising: a plurality of tray members arranged in tandem relation to define a pathway; certain of said trays having a bottom wall provided with means for longitudinally orienting an article; said bottom wall including longitudinal corrugations; adjacent transverse edges of bottom walls of adjacent trays being spaced longitudinally and vertically selected distances; and means extending from the edge portion of the uppermost tray over the space between said trays and over the adjacent edge of the lowermost tray to laterally restrict movement of articles being separated at the gap between said trays.
Claim 7
Dependent Claim 119 words
Means for separating articles according to at least one dimension and including vibratory conveyor means to move said articles along a path, comprising: a plurality of tray members arranged in tandem relation to define a pathway; certain of said trays having a bottom wall provided with means for longitudinally orienting an article; said bottom wall including mesh-like openings of selected width and length; adjacent transverse edges of bottom walls of adjacent trays being spaced longitudinally and vertically selected distances; and means extending from the edge portion of the uppermost tray over the space between said trays and over the adjacent edge of the lowermost tray to laterally restrict movement of articles being separated at the gap between said trays.
Claim 8
Dependent Claim 119 words
Means for separating articles according to at least one dimension and including vibratory conveyor means to move said articles along a path, comprising: a plurality of tray members arranged in tandem relation to define a pathway; certain of said trays having a bottom wall provided with means for longitudinally orienting an article; said bottom wall including mesh-like openings of selected width and length; adjacent transverse edges of bottom walls of adjacent trays being spaced longitudinally and vertically selected distances; and means extending from the edge portion of the uppermost tray over the space between said trays and over the adjacent edge of the lowermost tray to laterally restrict movement of articles being separated at the gap between said trays.
Claim 9
