ABSTRACT:
A tilting tray sorting conveyor comprising a track, a plurality of carriers on said track, a conveyor interconnecting said carriers and adapted to be driven to move said carriers along said track. Each carrier has a tray pivotally mounted thereon about an axis generally parallel to said track and a tilting yoke fixed thereto. Cam means along said track engage the tilting yoke and move said yoke in one direction to tilt said tray to one side and move said yoke in the other direction to tilt said tray to the opposite side of the track. Latch means are operable to hold said tray in normal upright position or to permit the tray to be tilted to one side or the other of said track. The latch means includes an escapement member mounted for generally vertical movement on the carriage and means yieldingly urging said escapement member to a neutral position corresponding to the upright position of said tray.
Interengaging means are provided between the escapement member and the tray such that when the escapement member is in neutral position, the tray is maintained in upright position, when the escapement member is moved in one direction from neutral, the tray is permitted to tilt to one side of the track, and when the escapement member is moved in the other direction from neutral, the tray is permitted to tilt to the opposite side of the track.
