Sorter conveyor having laterally tiltable trays
First Claim
1. A sorter conveyor of the type comprising a preferably endless row of laterally tiltable trays, which are carried forwards on associated carrier means along a conveyor chassis, which in several places is provided with activating means for selective activation of a tilting mechanism for the individual by-passing trays, characterized in that the tilting mechanism for an individual tray comprises a cylinder member which is transversely oriented relative the conveying direction of the tray and is turnable about a substantially horizontal axis which is fixed relative to the carrier means of the tray, said cylinder member being equipped with obliquely extending cam guiding tracks, which cooperate with a cam member mounted track follower, radially spaced from the longitudinally extending tilting axis of the tray, on a carrier part connected to the tray, and the cylinder member having at least at one end an axially projecting pin located radially spaced from the axis of the cylinder member in such a manner that this pin by operatively engaging the said activating means can produce a turning of the cylinder member, whereby the obliquely extending cam guiding track of the cylinder member forces the said cam track follower member to carry out a transverse movement resulting in a lateral tilting of the associated tray.

Abstract
For controlling the selective lateral tilting of the conveying trays of a sorter conveyor there is provided, on each tray support, a crosswise oriented cylinder, which by a protruding radial arm, is turnable between a "normal" position and a "tilt" postion in response to the radial arm engaging with an actuated guiding track associated with the stationary conveyor chassis. The tray has a lever engaging with an oblique cam track in the surface of the cylinder, whereby the tray is tilted by the turning of the cylinder. The cam track has non-oblique end portions, which lock the tray in both its horizontal and fully tilted position, without a separate lock being required. The cylinder may be split in two individually turnable halves selectively operable to tilt the tray to either side.
