Sortation equipment
First Claim
1. Sortation equipment for use in continuous track sortation systems, the equipment comprising:
- a train adapted to run on a continuous track for moving loads from a master station to one or more slave stations, the train having a locomotive and one or more cars coupled to be driven along the track by the locomotive, each of the cars including a tray tiltable from a load supporting generally horizontal position to a tilted position where the tray is inclined downwardly towards a slave station which is to receive the load off the tray, a discharge mechanism movable from a neutral to an intermediate position and then to an engagement position and including tray support means holding the tray horizontal with the discharge mechanism in the neutral and intermediate positions, and means on the train operable to move the discharge mechanism between the neutral and intermediate positions and the discharge mechanism being movable between the intermediate and engagement positions by contact with fixed means on the track at the slave station to drive the discharge mechanism as the train passes said fixed means whereby, as the discharge mechanism moves towards the engagement position, the tray is tilted to unload and then moved back to horizontal as the discharge mechanism returns to the intermediate position to again support the tray in the horizontal position;
whereby when the discharge mechanism is in said neutral position, the discharge mechanism is prevented from engaging said fixed means.

Abstract
The present invention provides a novel train and track which can be used in an automated, tracked soration system which is capable of sorting and transporting high volumes ofgoods efficiently and which gives flexible system design, easy set-up, easy servicing with minimum down time, centralized control and a minimum of wiring complexity. The train includes "smart" cars and a locomotive for pulling the cars around the track. The trains are loaded with goods to be sorted and given destination addresses for the goods at a loading or master station. Once a train has left the master station, all functions including keeping track of position, regulating speed and dumping cars are to be controlled by a microprocessor placed aboard each locomotive. This "smart" design allows the track to be very simple as it need only provide a path and lower supply for the trains to run on and the train can wait at the loading station until it has a full or partial load to deliver. Power feed lines are provided associated with the track to power the locomotive, and passive destination or slave stations are positioned about the track to receive sorted goods. Each dumping car includes a tray and a discharge mechanism. The trays are pivotable about an axis longitudinal to the cars and allows dumping to the sides of the track. Pivoting of these trays are controlled by the discharge mechanism which are movable from a neutral position to an intermediate position and to an engagement position. The tray pivots to dump when the discharge mechanism contacts a fixed object on the track. The pivoting is prevented when the discharge mechanism is in the neutral position.
