Definitions

  • a shuttle train consists of a plurality of cars, each car having a conveyor extending along the entire length of the car and inclined toward its rear end, each car further having a widened rear end adapted to receive the front end of the following car, so that the cars can be telescoped one into the other, the conveyors partially overlapping each other and cooperating with separating walls having projections slidable along the upper edge of the car body.
  • This invention refers to a shuttle train.
  • the invention is particularly concerned with a shuttle train having a plurality of cars each of which is provided with a conveyor extending the entire length of the car.
  • the cars can be spaced one from the other or they can be moved into a position in which they are telescoped one into the other.
  • Cars of this type are known in prior art.
  • known cars have the drawback that the front'ends of the cars must be raised before loading and unloading and that the cars must be lowered after the loading and unloading have been completed.
  • Practical experience has shown that these raising and lowering operations increase the manufacturing costs to a substantial extent and that they consume a substantial amount of time, so that the speed of operation of a train is greatly lowered.
  • An object of the present invention is to eliminate these drawbacks of existing constructions through the provision of a shuttle train which does not require the raising and lowering operations.
  • a conveyor extending with a constant inclination from the front end of a car to the rear end thereof, the car body having a widened portion at its rear end which can telescope with the front end of the following car, so that the material from the rear car can be forwarded to the front car.
  • the conveyors partially overlap each other and are adapted to cooperate with separating walls which at their upper ends are provided with projections slidable along the upper edge of the car body. The lower ends of the separating walls abut against driving pins provided in the conveyor.
  • FIG. 1 shows diagrammatically in side view a portion of a shuttle train of the present invention in a loading position
  • FIG. 2 is a top view of the train shown in FIG. 1;
  • FIG. 3 shows the same train in the driving position
  • FIG. 4 is a transverse section through the middle of a car body on an enlarged scale
  • FIG. 5 is a diagrammatic partial side view showing the separating wall of a car body.
  • FIG. 6 is a diagrammatic partial section showing driving pins engaged by rubber strips.
  • FIG. 6a is similar to FIG. 6 but shows the parts in a different position.
  • FIG. 1 The drawings show a car body 10 constituting a part of a shuttle train and having a front and a rear bogie 12, 14.
  • Each car body has a belt conveyor 16 arranged in a slightly inclined position so that the front end of the belt conveyor of each car in the loading or unloading position of the train can be guided over the rear end of the belt conveyor of the preceding car as shown in FIG. 1.
  • the angle of inclination may be about while the length of the upper conveyor belt may be about ll meters.
  • the upper part of the conveyor belt slides along the bottom 17 of the car body, as shown in FIG. 4.
  • the rear end 18 of each car body is somewhat wider than the remaining part of car body and also to a small degree higher, so that a jut will result.
  • the conveyor belts 16 are driven each by itself by means of compressed air motors, electromotors or hydraulic motors (not shown).
  • the front bogie 12 is provided with a coupling rod 19 while the other bogie 14 is provided with a coupling sleeve 20 so that the coupling rod 19 can be introduced into the sleeve 20 and locked in either loading and unloading position respectively, in which the rod 19 is set far into the sleeve 20.
  • the rod 19 is inserted into the sleeve 20 only by a length which is sufficient for locking the coupling by means of a crossbar 22 which extends through both the sleeve and the rod.
  • the coupling rod 19 can be shaped as a tube.
  • each car body At its front end the edge of each car body is provided with two vertical swingable flaps 24, the purpose of which is to close the space between the two car bodies 10 and 10' when they are telescoped into each other, as shown in FIGS. 1 and 2, so that the material to be transported is prevented from falling into this space and being squeezed therein.
  • the flaps 24 When the material is moved by means of the conveyor belt from one of the cars over to the preceding car, the flaps 24 are swung by the action of the material to abut against the inside of the end walls 18 of the preceding car.
  • the flaps 24 are spring-biassed so that they are returned automatically to the driving position (left side of FIG. 2) when the cars are moved apart from the position of FIG. 1 to the position of FIG. 3.
  • the wider portion 18 at the rear side of the car body is provided with a swinging flap 18 which can be moved outwardly to a slight extent to the position shown by broken lines in FIG. 2, in order to enable loading and unloading when the cars stand in a curve.
  • the flaps 18' may be actuated manually by means of a mechanism 26 comprising a screw spindle provided with a hand wheel placed under the flap and the jut.
  • the flaps 18' may be also operated by means of a hydraulic or air cylinder or by some other suitable means.
  • a device for preventing the material from falling out of the front end of the rear car at the passage between the two coupled cars.
  • a follower plate 28 which, according to FIG. 4, forms a separating wall within-the load space of the car body and which at its two side edges has arms 30 provided at their outer ends with projecting pivots 32 resting on and slidable along the upper edges of the car body.
  • clawlike stop pieces 34 At the front end of the cars and on the upper edge of the car body there are arranged clawlike stop pieces 34 for cooperation with the pivots 32 when the separating wall 28 is in its front end position.
  • the train consists of the two cars 10 and 10' shown in FIG. 1.
  • the separating wall 28 of the preceding car is moved to the right to the point B, the lower end of the separating wall 28 according to FIG. 5 abutting from the right against driving pins of the conveyor belt (position S) so that the separating wall cannot swing clockwise.
  • the separating wall 28 of the rear car 10 is also moved to point B where it assumes the position S.
  • the material to be transported now is loaded on the rear end of the rear car 10' against the separating wall and is gradually moved to the left by means of the conveyor belt 16.
  • a shuttle train having a plurality of cars, each of said cars comprising a car body having a front end and a rear end, a conveyor extending between said ends and being inclined downwardly toward the rear end, said rear end having a widened portion adapted to receive the front end of another car, the conveyors of two adjacent cars having overlapping end portions, separating walls swingably mounted upon said car body adjacent the ends thereof, arms carried by said walls, pivots carried by said arms and slidable along the upper edges of said car body, and pins carried by said conveyor and adapted to engage the lowerportions of said walls.
  • a shuttle train in accordance with claim 1, comprising vertical flaps swingably mounted adjacent the front end of the car body.
  • a shuttle train in accordance with claim 1, comprising flaps mounted upon the widened rear end portion of the car body and swingable outwardly relatively to the car body.
  • a shuttle train in accordance with claim 1, comprising rubber strips connected to said car body and adapted to engage said pins.
