Diagonal sorter
First Claim
1. A switch comprising:
- an infeed conveyor conveying articles in a conveying direction;
an outbound conveyor including a plurality of outbound conveyor lanes receiving articles and conveying the articles in the conveying direction;
a sorting conveyor disposed on a diagonal oblique to the conveying direction between the infeed conveyor and the outbound conveyor and comprising a belt advancing along the diagonal and having rollers selectively rotatable transverse to the diagonal toward the outbound conveyor in roller actuation zones sequentially disposed along the length of the sorting conveyor to push the articles received from the infeed conveyor onto the outbound conveyor at a selected position along the sorting conveyor.

Abstract
In one embodiment, a conveyor system includes a conveyor belt having a plurality of conveyor belt rollers configured to divert articles on the conveyor belt, and a drive mechanism that engages the conveyor belt rollers, the drive mechanism being configured to drive the conveyor belt rollers, the drive mechanism being adjustable such that the conveyor belt rollers can be selectively driven in a first angular direction and, optionally, a second, opposite angular direction so that articles can be selectively diverted to either side of the conveyor belt at a desired diverting angle. One version of the drive mechanism has drive rollers mounted in cartridges and rack gears engaging pinion gears on the cartridges to adjust the orientation of the drive rollers relative to the belt rollers to drive them in selectively opposite angular directions. Such a conveyor system with a series of sequential roller actuation zones driven by separately actuated drive mechanisms is arranged diagonally to an infeed conveyor and a multi-lane outbound conveyor to realize a switch conveyor.

1. A switch comprising:
-
an infeed conveyor conveying articles in a conveying direction; an outbound conveyor including a plurality of outbound conveyor lanes receiving articles and conveying the articles in the conveying direction; a sorting conveyor disposed on a diagonal oblique to the conveying direction between the infeed conveyor and the outbound conveyor and comprising a belt advancing along the diagonal and having rollers selectively rotatable transverse to the diagonal toward the outbound conveyor in roller actuation zones sequentially disposed along the length of the sorting conveyor to push the articles received from the infeed conveyor onto the outbound conveyor at a selected position along the sorting conveyor. - View Dependent Claims (2, 3, 4, 5, 6, 7)

8. A switch comprising:
-
an infeed conveyor having an exit end and conveying articles in a conveying direction toward the exit end; a plurality of outbound conveyor lanes having entrance ends and conveying articles in the conveying direction from the entrance ends; a sorting conveyor extending in length diagonally between the exit end of the infeed conveyor and the entrance ends of the outbound conveyor lanes from an upstream end to a downstream end between parallel first and second sides, wherein the infeed conveyor feeds articles to the sorting conveyor over the first side at an upstream position and the outbound lanes receive articles from the sorting conveyor over the second side at the entrance ends, the sorting conveyor including; a roller belt advancing along the length of the sorting conveyor in a direction of belt travel oblique to the conveying direction and having article-supporting belt rollers selectively rotatable on axes parallel to the direction of belt travel; a series of belt-roller actuation zones underlying the roller belt along the length of the sorting conveyor to selectively rotate the belt rollers in each zone toward the second side to push supported articles toward the outbound conveyor lanes. - View Dependent Claims (9, 10, 11, 12, 13)

14. A method for making a switch, comprising:
-
providing a sorting conveyor having a belt with plurality of actuatable article-supporting rollers arranged to be selectively rotated in a direction perpendicular to a direction of belt travel in roller actuation zones sequentially disposed along the length of the sorting conveyor; arranging an infeed conveyor to feed articles onto the sorting conveyor in a conveying direction oblique to the direction of belt travel from a first side of the sorting conveyor; arranging an outbound conveyor on the opposite second side of the sorting conveyor with a plurality of lanes parallel to the conveying direction, wherein the lanes are arranged to receive articles from the sorting conveyor over the second side.
