Patent number: 5988351Abstract: A conveyor of product units has mounting brackets extending laterally from endless chains. The mounting brackets rotatably mount two spools having axes parallel to the conveying path. The mounting brackets are displaced longitudinally one from another. Consequently, a central elongate cavity is defined along the conveying path between laterally adjacent spools. Further, lateral concavities are presented between rollers on individual spools and between rollers on separate spools. Pivotally mounted off-loading elements can be articulated to lift product units positioned on the conveying system for off-loading laterally from the conveyor. A laterally articulated actuator is located below the principal conveyor. The actuator includes laterally slidable slats which frictionally engage the overlying rollers associated with each mounting bracket. Guides are then arranged to move the slats laterally with motion of the conveyor. With lateral motion of the slats, the rollers are caused to rotate.Type: GrantFiled: February 19, 1997Date of Patent: November 23, 1999Inventor: A. James Warkentin

Patent number: 5855270Abstract: A fruit or other produce orienting device, particularly suited for orienting apples, orients a piece of fruit with its stem axis horizontal so that it can undergo quality inspections. The device employs a cylindrical drive roller which engages the fruit on one side, and causes it to rotate, and a pair of freely rotating orienting rollers which engage the fruit across from the drive roller, and cause the fruit to achieve the desired orientation as it rotates. The first orienting roller is cone shaped with a tapered flat or concave surface so that it will steer the fruit toward the second, opposing roller, which has a thin disk shaped portion with a front surface that engages the fruit. The front surface of the disk shaped portion tends to align itself with the flat edge of the fruit at its stem or calyx end, and this causes the rotating fruit to be oriented quickly with its stem axis parallel to the roller axes, and then maintains the fruit in the correct orientation once it is achieved.Type: GrantFiled: October 23, 1996Date of Patent: January 5, 1999Assignees: Cornell Research Foundation, Inc., U.S. Dept. of AgricultureInventors: James A.

Patent number: 5267654Abstract: An article-holding cup that has a pair of rotatable rollers for supporting an article thereon, an L-shaped arm extending outward and downward from one side, a second arm extending outward from an opposite side, and a pivotable connector for attaching the cup with others to one of a pair of conveyors in an article sorting apparatus for carrying in a direction of conveyance through a loading zone, a property-determining zone, and a discharge zone. The rollers rotate in response to a wheel rolling on a plate in a property-determining zone to expose different surface areas of the article to optical scanners. A scale and the optical sensor determine weight and color properties of each article during a single pass through the property-determining zone. The cups have lost motion in the vertical direction and travel on rails in the weighing zone, so that the weight of the article in each cup may be determined independently of the conveyor.Type: GrantFiled: May 26, 1992Date of Patent: December 7, 1993Assignee: Durand-Wayland, Inc.Inventor: William H.

Patent number: 5190137Abstract: This invention relates to an apparatus for orienting spherical products having at least one substantially flattened surface, such as tomatoes and the like. The apparatus comprises a roller conveyor whose rollers are rotatable about their axis, while the free space between successive rollers is smaller than the greatest diameter of the product to be oriented. The roller conveyor further comprises members projecting above the top surface of the rollers to form conveyor compartments for receiving therein one product to be oriented. According to the invention, the center-to-center distance between successive rollers of the conveyor (1) is at most equal to the diameter of the flattened surface of the product to be sorted.Type: GrantFiled: April 26, 1991Date of Patent: March 2, 1993Inventor: Adrianus W.

Patent number: 5181596Abstract: An off-loading conveyor including a support structure mounting an endless chain to extend along a conveying path. Roller carriages including roller mounts and laterally extending elements are pivotally mounted to the chain on either side thereof. The laterally extending elements and the laterally extending rollers define cavities for receipt of conveyed product units. The roller carriages and associated rollers are positionable in a first, conveying position and a second, off-loading position. The roller carriages rotate downwardly about axes extending laterally of the chain to achieve the second, off-loading position. Control members pivotally mounted to the chain selectively control rotation of the roller carriages from the first to the second positions upon actuation by a solenoid cam mechanism.Type: GrantFiled: May 8, 1991Date of Patent: January 26, 1993Inventor: A.
