DESCRIPTION:
BRIEF SUMMARY
FIELD OF THE INVENTION
The present invention provides a method for maximizing the loading capacity of a wagon or wagon train when loading with pourable material from a silo. More particularly, the method utilizes a computer which determines the type of wagon to be loaded on the basis of values obtained with sensors.
BACKGROUND OF THE INVENTION
Bulk materials are normally loaded onto railway freight cars or wagons, by passing a number of mutually hitched wagons through a loading zone above which there is arranged a storage unit or silo in which bulk materials, such as ore concentrates or pellets, are stored. The material is discharged from the silo down into an underlying wagon through the medium of a chute provided with an outlet opening, referred to here as a material delivery chute. Loading of the wagons takes place automatically and the outlet end of the delivery chute is provided with a flap whose width is sufficient to cause the material pouring from the chute to be distributed uniformly in the wagon.
Australian Publication B 55576/86 teaches one such type of loading arrangement where the intention is to distribute the weight of the material equally at both ends of the wagon while, at the same time, maintaining an essentially constant height, or level of the material in the wagon, therewith to utilize the capacity of the wagon effectively. To this end, the wagon is weighed and its height is determined and also its passage through specific points. On the basis of this information, the material delivery chute is controlled to deliver a specific volume or weight of material to the wagon and to distribute the material uniformly in the wagon while levelling the material therein at the same time.
When seen against the background of the number of wagons that annually transport bulk materials of the aforesaid kind, such as ore, ore concentrates or pellets, it is a natural aim to utilize the load capacity of each wagon and each wagon train to a maximum. Wagon wheels and wagon baskets become worn and in time a wagon may become one or two tonnes lighter in weight. Its loading capacity has not diminished, however. The endeavour to constantly utilize the full load capacity of individual wagons or freight cars is readily understandable.
SUMMARY OF THE INVENTION
The present invention relates to a method which enables this to be achieved in accordance with the characterizing features set forth in the following claims.
A method of utilizing the loading capacity of a wagon and a wagon train to a maximum when loading with pourable material, particularly bulk material, from a silo with the aid of a raisable and lowerable delivery chute having an outlet opening, down into a wagon moving beneath the chute. The by-passing wagon to be filled is weighed and its empty weight registered. The method is characterized by registering the type of by-passing wagon to be filled and by feeding to a computer registered data representing the weight of an empty wagon and the type of wagon concerned. This data, in the form of signals, is fed into the computer and the computer functions to move the outlet opening of the chute to a height above the bottom of the wagon in accord with the type of wagon concerned on the basis of said data and the density of the bulk material through the medium of manoeuvering devices wherein the height at which the chute outlet opening is located above the bottom determines the volume of bulk material that corresponds to the maximum permitted total weight of this individual wagon .
